2,6-di-hidroxiacetofenona no enraizamento de estacas semilenhosas de pessegueiro
Provedor de dados: 94
Autores: Tofanelli,Mauro Brasil Dias; Ono,Elizabeth Orika; Rodrigues,João Domingos.
A propagação do pessegueiro no Brasil baseia-se na enxertia de cultivares-copa em porta-enxertos propagados por sementes, e uma alternativa de propagação para esta frutífera poderia ser a estaquia. O objetivo deste trabalho foi avaliar o potencial de enraizamento de estacas semilenhosas de cultivares de pessegueiro através da aplicação de 2,6-di-hidroxiacetofonona (2,6-DHAP) antes do tratamento com AIB (ácido indolbutírico). As estacas foram preparadas a partir de ramos coletados das cultivares Delicioso Precoce, Jóia 1 e Okinawa, em dezembro de 2001, para serem tratadas na base com 2,6-DHAP (0 e 300mg L-1), por 4h, em aeração e depois com AIB (200mg L-1 e 2500mg L-1). As estacas foram plantadas em bandejas de poliestireno expandido com vermiculita fina e...

4-Aminopyridine inhibits the neuromuscular effects of nitric oxide and 8-Br-cGMP
Provedor de dados: 56
Autores: Queiroz,R.N.; Ramos,E.R.P.; Alves-Do-Prado,W.
The effects induced by nitric oxide (NO) in different tissues depend on direct and/or indirect interactions with K+ channels. The indirect interaction of NO is produced by activation of guanylyl cyclase which increases the intracellular cGMP. Since NO, cGMP and 4-aminopyridine alone induce tetanic fade and increase amplitude of muscular contractions in isolated rat neuromuscular preparations, the present study was undertaken to determine whether or not the neuromuscular effects of NO and 8-Br-cGMP can be modified by 4-aminopyridine. Using the phrenic nerve and diaphragm muscle isolated from male Wistar rats (200-250 g), we observed that L-arginine (4.7 mM) and 8-Br-cGMP (18 µM), in contrast to D-arginine, induced an increase in the amplitude of muscle...

5-HT1A autoreceptor modulation of locomotor activity induced by nitric oxide in the rat dorsal raphe nucleus
Provedor de dados: 56
Autores: Gualda,L.B.; Martins,G.G.; Müller,B.; Guimarães,F.S.; Oliveira,R.M.W.
The dorsal raphe nucleus (DRN) is the origin of ascending serotonergic projections and is considered to be an important component of the brain circuit that mediates anxiety- and depression-related behaviors. A large fraction of DRN serotonin-positive neurons contain nitric oxide (NO). Disruption of NO-mediated neurotransmission in the DRN by NO synthase inhibitors produces anxiolytic- and antidepressant-like effects in rats and also induces nonspecific interference with locomotor activity. We investigated the involvement of the 5-HT1A autoreceptor in the locomotor effects induced by NO in the DRN of male Wistar rats (280-310 g, N = 9-10 per group). The NO donor 3-morpholinosylnomine hydrochloride (SIN-1, 150, and 300 nmol) and the NO scavenger...

A 28-fold increase in secretory protein synthesis is associated with DNA puff activity in the salivary gland of Bradysia hygida (Diptera, Sciaridae)
Provedor de dados: 56
When the first group of DNA puffs is active in the salivary gland regions S1 and S3 of Bradysia hygida larvae, there is a large increase in the production and secretion of new salivary proteins demonstrable by [3H]-Leu incorporation. The present study shows that protein separation by SDS-PAGE and detection by fluorography demonstrated that these polypeptides range in molecular mass from about 23 to 100 kDa. Furthermore, these proteins were synthesized mainly in the S1 and S3 salivary gland regions where the DNA puffs C7, C5, C4 and B10 are conspicuous, while in the S2 region protein synthesis was very low. Others have shown that the extent of amplification for DNA sequences that code for mRNA in the DNA puffs C4 and B10 was about 22 and 10 times,...

A brief inventory of sand flies (Diptera, Psychodidae) from the National Forest of the Rio Preto, state of the Espírito Santo, southeastern Brazil
Provedor de dados: 49
Autores: Pinto,Israel de Souza; Tonini,João Filipe Riva; Ferreira,Adelson Luiz; Falqueto,Aloísio.
The inventories on sand flies are usually conducted for a long period in leishmaniasis-endemic regions. Thus, there is little data on the sand fly fauna in areas where no leishmaniasis cases have been reported. Therefore, we conducted an inventory to study the sand fly fauna in the National Forest of Rio Preto (NFRP). We carried out a brief inventory by using four CDC light traps in 2009 during winter and summer. We collected 1,403 sand flies belonging to 11 genera and 22 species. As expected, we did not find in the NFRP region sand flies species that have been reported as vectors of Leishmania. However, we found some species of sand flies with few records and that rarely have been reported in southeastern Brazil. Nevertheless, the diversity and species...

A calcineurin inhibitory protein overexpressed in Down's syndrome interacts with the product of a ubiquitously expressed transcript
Provedor de dados: 56
Autores: Silveira,H.C.S.; Sommer,C.A.; Soares-Costa,A.; Henrique-Silva,F.
The Down's syndrome candidate region 1 (DSCR1) protein, encoded by a gene located in the human chromosome 21, interacts with calcineurin and is overexpressed in Down's syndrome patients. As an approach to clarifying a putative function for this protein, in the present study we used the yeast two-hybrid system to identify DSCR1 partners. The two-hybrid system is a method that allows the identification of protein-protein interactions through reconstitution of the activity of the yeast GAL 4 transcriptional activator. The gene DSCR1 fused to the GAL 4 binding domain (BD) was used to screen a human fetal brain cDNA library cloned in fusion with the GAL 4 activation domain (AD). Three positive clones were found and sequence analysis revealed that all the...

A comparative study of eleven protein systems in tamarins, genus Saguinus (Platyrrhini, Callitrichinae)
Provedor de dados: 54
The genetic variability of six tamarin taxa, genus Saguinus, was analyzed comparatively using protein data from eleven systems coded by 15 loci. S. fuscicollis weddelli and S. midas midas were the most polymorphic taxa, and S. bicolor the least. The results of the phylogenetic analyses (UPGMA and neighbor-joining) and the genetic distances between taxa were generally consistent with their geographic and probable phylogenetic relationships. Analyses of the S. bicolor and S. midas populations suggested that they represent no more than three subspecies of a single species, S. midas, with the bicolor forms belonging to a single subspecies, S. midas bicolor. If supported by additional studies, this would have important implications for the conservation of the...

Autores: Arraes,L.C.; de Souza,P.R.; Bruneska,D.; Castelo Filho,A.; de Souza Cavada,B.; de Lima Filho,J.L.; Crovella,S.
We report a fast (less than 3 h) and cost-effective melting temperature assay method for the detection of single-nucleotide polymorphisms in the MBL2 gene. The protocol, which is based on the Corbett Rotor Gene real time PCR platform and SYBR Green I chemistry, yielded, in the cohorts studied, sensitive (100%) and specific (100%) PCR amplification without the use of costly fluorophore-labeled probes or post-PCR manipulation. At the end of the PCR, the dissociation protocol included a slow heating from 60º to 95ºC in 0.2ºC steps, with an 8-s interval between steps. Melting curve profiles were obtained using the dissociation software of the Rotor Gene-3000 apparatus. Samples were analyzed in duplicate and in different PCR runs to test the reproducibility of...

A direct contact between astrocyte and vitreous body is possible in the rabbit eye due to discontinuities in the basement membrane of the retinal inner limiting membrane
Provedor de dados: 56
Autores: Haddad,A.; Salazar,J.J.; Laicine,E.M.; Ramírez,A.I.; Ramírez,J.M.; Triviño,A.
Different from most mammalian species, the optic nerve of the rabbit eye is initially formed inside the retina where myelination of the axons of the ganglion cells starts and vascularization occurs. Astrocytes are confined to these regions. The aforementioned nerve fibers known as medullated nerve fibers form two bundles that may be identified with the naked eye. The blood vessels run on the inner surface of these nerve fiber bundles (epivascularization) and, accordingly, the accompanying astrocytes lie mostly facing the vitreous body from which they are separated only by the inner limiting membrane of the retina. The arrangement of the astrocytes around blood vessels leads to the formation of structures known as glial tufts. Fragments (N = 3) or whole...

A exploração da fauna silvestre no Brasil: Jacarés, sistemas e recursos humanos
Provedor de dados: 49
Autores: Verdade,Luciano M.
A conservação da vida silvestre normalmente necessita de estudos caso a caso porque a população - e não a espécie - deve ser na maioria das vezes a unidade do manejo. No Brasil, a falta de uma categoria profissional específica, como a dos wildlife biologists norte-americanos, dificulta a implantação de programas de conservação e manejo de vida silvestre. O preconceito contra o uso da fauna como recurso natural renovável, o abuso da criação em cativeiro e a noção de que o país não é capaz de implantar com sucesso um programa de fiscalização eficaz impedem a implantação de sistemas biologicamente sustentáveis, economicamente viáveis e socialmente justificáveis de uso da fauna silvestre. Isto só poderá mudar através da formação adequada de recursos humanos,...

On 06 October 2012 a pod of Rough-toothed Dolphins Steno bredanensis (Delphinidae) was observed catching and tearing apart several Castin Leatherjacks Oligoplites saliens (Carangidae) near Montão de Trigo Island, northern coast of São Paulo, Brazil. The resulting floating masses of viscera attracted a feeding aggregation of 120-150 Wilson's Storm-petrels Oceanites oceanicus (Hydrobatidae), a transequatorial migrant passing through the area during October. This interspecific association has not been recorded before, although it could be expected given that S. bredanensis feeds on large fish and O. oceanicus is a known scavenger of kills made by cetaceans such as Killer Whales.

A high-fructose diet induces changes in pp185 phosphorylation in muscle and liver of rats
Provedor de dados: 56
Autores: Ueno,M.; Bezerra,R.M.N.; Silva,M.S.; Tavares,D.Q.; Carvalho,C.R.; Saad,M.J.A.
Insulin stimulates the tyrosine kinase activity of its receptor resulting in the tyrosine phosphorylation of pp185, which contains insulin receptor substrates IRS-1 and IRS-2. These early steps in insulin action are essential for the metabolic effects of insulin. Feeding animals a high-fructose diet results in insulin resistance. However, the exact molecular mechanism underlying this effect is unknown. In the present study, we determined the levels and phosphorylation status of the insulin receptor and pp185 (IRS-1/2) in liver and muscle of rats submitted to a high-fructose diet evaluated by immunoblotting with specific antibodies. Feeding fructose (28 days) induced a discrete insulin resistance, as demonstrated by the insulin tolerance test. Plasma...

A holoparasitic plant severely reduces the vegetative and reproductive performance of its host plant in the Caatinga, a Brazilian seasonally dry forest
Provedor de dados: 39
Autores: Cruz Neto,Oswaldo; Leal,Inara Roberta; Santos,Jean Carlos; Lopes,Ariadna Valentina.
ABSTRACT Host-parasite interactions between plants may reduce the vegetative and reproductive performance of the host plant. Although it is well established that parasitic plants may negatively affect the metabolism and the number of vegetative/reproductive structures of their hosts, the effects of this interaction on the reproductive characteristics of the host plant are poorly understood. Here we document the interaction between Cuscuta partita (Convolvulaceae) and its main host, Zornia diphylla (Fabaceae), in the Caatinga of northeastern Brazil. We measured diverse reproductive/vegetative attributes of Z. diphylla in 60 plots randomly distributed in patches that were parasitized and not parasitized by C. partita. Both vegetative and reproductive...

A laboratory cage for foster nursing newborn mice
Provedor de dados: 56
Autores: Marques-de-Araújo,S.; Cardoso,M.A.
We describe a cage to be used for foster nursing in order to guarantee that original mother's colostrum is not ingested by the newborn mice. A common (30.5 cm x 19.5 cm x 12.0 cm) mouse cage was fitted with a wire net tray with a mesh (1 cm x 1 cm), which divides the cage into an upper and a lower compartment. Mice born to females placed in the upper compartment pass through the mesh and fall into the lower compartment, where another lactating female with one or two of its own pups are. Of a total of 28 newborn mice of C3H/He and Swiss strains, 23 were successfully fostered. Important observations are presented to show that this is a valuable alternative for foster studies without great suffering on the part of the female.

Provedor de dados: 56
Autores: Gomes-Marcondes,M.C.C.; Ventrucci,G.; Toledo,M.T.; Cury,L.; Cooper,J.C.
Cancer cachexia induces host protein wastage but the mechanisms are poorly understood. Branched-chain amino acids play a regulatory role in the modulation of both protein synthesis and degradation in host tissues. Leucine, an important amino acid in skeletal muscle, is higher oxidized in tumor-bearing animals. A leucine-supplemented diet was used to analyze the effects of Walker 256 tumor growth on body composition in young weanling Wistar rats divided into two main dietary groups: normal diet (N, 18% protein) and leucine-rich diet (L, 15% protein plus 3% leucine), which were further subdivided into control (N or L) or tumor-bearing (W or LW) subgroups. After 12 days, the animals were sacrificed and their carcass analyzed. The tumor-bearing groups showed a...

Provedor de dados: 56
Autores: Cardoso,T.C.; Mouro-Sousa,R.L.; Oliveira,C.; Stringhini,G.; Augusto-Pinto,A.
A liquid phase blocking ELISA (LPB-ELISA) was developed for the detection and measurement of antibodies against infectious bronchitis virus (IBV). The purified and nonpurified virus used as antigen, the capture and detector antibodies, and the chicken hyperimmune sera were prepared and standardized for this purpose. A total of 156 sera from vaccinated and 100 from specific pathogen-free chickens with no recorded contact with the virus were tested. The respective serum titers obtained in the serum neutralization test (SNT) were compared with those obtained in the LPB-ELISA. There was a high correlation (r2 = 0.8926) between the two tests. The LPB-ELISA represents a single test suitable for the rapid detection of antibodies against bronchitis virus in...

A liver metalloendopeptidase which degrades the circulating hypotensive peptide hormones bradykinin and atrial natriuretic peptide
Provedor de dados: 56
Autores: Carvalho,K.M.; Nava,R.A.; França,M.S.F.; Medeiros,M.A.S.; Camarão,G.C.; Juliano,L.
A new metalloendopeptidase was purified to apparent homogeneity from a homogenate of normal human liver using successive steps of chromatography on DEAE-cellulose, hydroxyapatite and Sephacryl S-200. The purified enzyme hydrolyzed the Pro7-Phe8 bond of bradykinin and the Ser25-Tyr26 bond of atrial natriuretic peptide. No cleavage was produced in other peptide hormones such as vasopressin, oxytocin or Met- and Leu-enkephalin. This enzyme activity was inhibited by 1 mM divalent cation chelators such as EDTA, EGTA and o-phenanthroline and was insensitive to 1 µM phosphoramidon and captopril, specific inhibitors of neutral endopeptidase (EC 3.4.24.11) and angiotensin-converting enzyme (EC 3.4.15.1), respectively. With Mr 85 kDa, the enzyme exhibits optimal...

Provedor de dados: 56
Autores: Lopes,A.A.; Soares,R.P.S.; Maeda,N.Y.
The objective of the present study was to establish a method for quantitative analysis of von Willebrand factor (vWF) multimeric composition using a mathematical framework based on curve fitting. Plasma vWF multimers from 15 healthy subjects and 13 patients with advanced pulmonary vascular disease were analyzed by Western immunoblotting followed by luminography. Quantitative analysis of luminographs was carried out by calculating the relative densities of low, intermediate and high molecular weight fractions using laser densitometry. For each densitometric peak (representing a given fraction of vWF multimers) a mean area value was obtained using data from all group subjects (patients and normal individuals) and plotted against the distance between the peak...

A moderate decrease in temperature inhibits the calcium signaling mechanism(s) of the regulatory volume decrease in chick embryo cardiomyocytes
Provedor de dados: 56
Autores: Souza,M.M.; Boyle,R.T.
Chick cardiomyocytes, when submitted to hyposmotic swelling, exhibit a partial regulatory volume decrease (RVD). A Ca2+ influx by stretch-activated channels signals a taurine efflux and the RVD at 37°C. We evaluated the cell's performance at room temperature. Cardiomyocytes isolated and cultured from 11-day-old chick embryos were submitted to a hyposmotic solution (180 mOsm/kg H2O) at 37°C and at room temperature (26°C). Under these conditions we measured the changes in cell volume as well as the intracellular free Ca2+ (using fura-2). During hyposmotic swelling, cells at 37°C displayed a peak relative volume of 1.61 ± 0.03 and recovery to 1.22 ± 0.04 (N = 14), while cells at 26°C presented a peak swell relative volume of 1.74 ± 0.06 and did not recover...

The stingless bee species Melipona quadrifasciata includes two subspecies, Melipona quadrifasciata anthidioids and Melipona quadrifasciata quadrifasciata. The morphological difference between the two subspecies is the presence of three to five continuous yellow stripes on the terga on the 3rd to 6th segments in workers and males of M. q. quadrifasciata, and two to five interrupted bands in M. q. anthidioides. We identified a DNA marker which is present in M. q. quadrifasciata and absent in M. q. anthidioides. Only one among the M. q. quadrifasciata colonies did not present the marker. It was also absent in bees collected in northern Minas Gerais State (Brazil), despite their morphological resemblance to M. q. quadrifasciata. The marker can be used for...

A recessive mutant cell line, B7, which is partially responsive to both interferon (IFN)-&lt;FONT FACE="Symbol"&gt; a&lt;/font&gt; and IFN-&lt;FONT FACE="Symbol"&gt;g&lt;/font&gt; is described. B7 was FACS sorted from a cellular pool, which was obtained from the parental cell line 2C4, after several rounds of mutagenesis. The partial responsiveness to IFN was observed both in terms of expression of cell surface markers (CD2, class I and II HLAs) and mRNA expression of IFN-stimulated genes (9-27; 6-16; 2'-5' OAS; GBP and HLA-DRa). A genetic cross with the U4 mutant (JAK1-, a member of the Janus family of nonreceptor tyrosine kinase) did not restore full IFN-responsiveness to B7, and JAK1 cDNA transfection into B7 restored the wild phenotype of the cell...

An alternative device for the immobilization of the hind limb of the rat was developed to study the effects of chronic disuse on the soleus and tibialis anterior muscles, maintained for 3 weeks in the shortening and the stretching positions, respectively. The proposed device is made of steel mesh and cotton materials, and has some advantages when compared to cast or plaster cast: it is cheaper, lighter (12 g or 4% of the body weight of the rat) and the same unit can be easily adjusted and used several times in the same animal or in animals of similar size. Immobilization is also useful to restrain the movements of the hip, knee, and ankle joints. Male rats (291 ± 35 g and aged 14 ± 2 weeks) were used to develop and test the model.

ABSTRACT Herein, we report a new record of the milk frog Trachycephalus coriaceus for the Brazilian southern Amazonia and provide an updated geographic distribution map. We collected one specimen of T. coriaceus on 8 november 2016, during a nocturnal survey inside a dense ombrophilous forest in the right bank of the Teles Pires River, municipality ofJacareacanga, southern of Pará State. The record of T. coriaceus to Jacareacanga is the first to the State. The disjoint geographic distribution of this species along de Amazonia may just reflect the paucity of amphibian knowledge throughout this biome and the difficulty to detect this species in the field, given its explosive reproductive behavior.

A new technique in the excavation of ground-nest bee burrows (Hymenoptera: Apoidea)
Provedor de dados: 92
Autores: Marinho,Diego; Andrade,Juliana; Araujo,Rodrigo O.; Vivallo,Felipe.
ABSTRACT Bees have a diversified natural history, thus the methods applied to study such diversity are varied. When it comes to studies of nesting biology, bees which nest in pre-existing cavities have been reasonably well studied since researchers started using trap-nests. However, bees whose nests are built underground are poorly studied due to the difficulty of finding natural nesting areas and the absence of a method that facilitates bee nest excavation. The latter is evidenced by the lack of accurate descriptions in literature of how nests are excavated. In this study we tested cylindrical rubber refills of eraser pen as a new material to be used as a tracer of underground nest galleries in a natural nesting area of two species of Epicharis Klug, 1807...

A novel c.197T ® A variant among Brazilian neonates with glucose-6-phosphate dehydrogenase deficiency
Provedor de dados: 74
Autores: Moura Neto,José Pereira de; Dourado,Marcos Vinícius; Reis,Mitermayer Galvão dos; Gonçalves,Marilda Souza.
Glucose-6-phosphate dehydrogenase (G6PD, EC 1.1.1.49) deficiency is the most common enzyme deficiency worldwide, causing a spectrum of diseases including neonatal hyperbilirubinemia and acute or chronic hemolysis. We used the methemoglobin reduction test and G6PD electrophoresis to screen 655 neonates (354 females and 301 males) for common G6PD mutations in the city of Salvador in the Northeastern Brazilian state Bahia and found that 66 (10.1%) were G6PD-deficient (41 females and 25 males). The 66 (10.1%) G6PD-deficient neonates were assessed for the c.376 A -&gt; G (exon 5) and c.202 G -&gt; A (exon 4) mutations using the polymerase chain reaction and restriction enzyme fragment length polymorphism (PCR-RFLP) analysis and the results validated by DNA...

A novel missense mutation p.L76P in the GJB2 gene causing nonsyndromic recessive deafness in a Brazilian family
Provedor de dados: 56
Autores: Batissoco,A.C.; Auricchio,M.T.B.M.; Kimura,L.; Tabith-Junior,A.; Mingroni-Netto,R.C.
Mutations in the GJB2 gene, encoding connexin 26 (Cx26), are a major cause of nonsyndromic recessive hearing loss in many countries. We report here on a novel point mutation in GJB2, p.L76P (c.227C&gt;T), in compound heterozygosity with a c.35delG mutation, in two Brazilian sibs, one presenting mild and the other profound nonsyndromic neurosensorial hearing impairment. Their father, who carried a wild-type allele and a p.L76P mutation, had normal hearing. The mutation leads to the substitution of leucine (L) by proline (P) at residue 76, an evolutionarily conserved position in Cx26 as well as in other connexins. This mutation is predicted to affect the first extracellular domain (EC1) or the second transmembrane domain (TM2). EC1 is important for...

A novel polymorphism in the coding region of the vasopressin type 2 receptor gene
Provedor de dados: 56
Nephrogenic diabetes insipidus (NDI) is a rare disease characterized by renal inability to respond properly to arginine vasopressin due to mutations in the vasopressin type 2 receptor (V2(R)) gene in affected kindreds. In most kindreds thus far reported, the mode of inheritance follows an X chromosome-linked recessive pattern although autosomal-dominant and autosomal-recessive modes of inheritance have also been described. Studies demonstrating mutations in the V2(R) gene in affected kindreds that modify the receptor structure, resulting in a dys- or nonfunctional receptor have been described, but phenotypically indistinguishable NDI patients with a structurally normal V2(R) gene have also been reported. In the present study, we analyzed exon 3 of the...

A novel postharvest rot of okra pods caused by Rhizoctonia solani in Brazil
Provedor de dados: 102
Autores: Henz,Gilmar P.; Lopes,Carlos A.; Reis,Ailton.
Okra pods with unusual brown lesions and rot were collected in a local supermarket in Brasília DF. The objective of this paper was to characterize the causal agent, to fulfill Koch's postulates and to determine some conditions conducive to disease. The pathogen was identified as Rhizoctonia solani based on morphological characteristics which fitted the fungus description, such as pale to brown hyphae, with nearly right-angled side branches constricted at the base, hyphal cells 6-10 µm wide with a septum near the base. Five isolates were obtained from infected pods and identified as AG 1-IB anastomosis group. Wounded or unwounded okra pods cv. Santa Cruz 47 were inoculated with mycelium disks of R. solani and kept in humid chambers at 12 ºC or 25 ºC. After...

A polymerase chain reaction-based assay to identify genotype F of hepatitis B virus
Provedor de dados: 56
Autores: Moraes,M.T.B.; Niel,C.; Gomes,S.A.
We have developed a polymerase chain reaction (PCR) assay which distinguishes genotype F from the other genotypes of hepatitis B virus (HBV). The method was used to characterize HBV strains isolated in urban areas of the Brazilian Amazon. DNA was amplified in 54 of a total of 78 HBsAg-positive serum samples, using universal, non-genotype-specific primers. Only 4 (7.4%) were identified as genotype F by our genotype-specific PCR assay. This proportion is notably lower than that previously reported in Argentina, Venezuela, Peru, and Central America.

A practical method for screening for beta-galactosidase secreting microbial colonies
Provedor de dados: 58
Autores: Barreto,Eriana S.; Silva,Daison O.; Passos,Flavia M. Lopes.
Microbial colonies were replicated on YNB® agar plates overlaid with soft agar containing the glucose-oxidase/peroxidase (BIOTROL®) system. The pink color developed around the colonies was the result of the reaction of the glucose generated by the extracellular hydrolysis of lactose by beta-galactosidase, indicating secretion of this enzyme. This method proved to be very convenient for testing hundreds of colonies grown on agar plates for beta-galactosidase secretion by microbial cells.

Autores: Liu,Xiao Lei; Liu,Su Lin; Liu,Min; Kong,Bi He; Liu,Lei; Li,Yan Hong.
Investigating the endophytic bacterial community in special moss species is fundamental to understanding the microbial-plant interactions and discovering the bacteria with stresses tolerance. Thus, the community structure of endophytic bacteria in the xerophilous moss Grimmia montana were estimated using a 16S rDNA library and traditional cultivation methods. In total, 212 sequences derived from the 16S rDNA library were used to assess the bacterial diversity. Sequence alignment showed that the endophytes were assigned to 54 genera in 4 phyla (Proteobacteria, Firmicutes, Actinobacteria and Cytophaga/Flexibacter/Bacteroids). Of them, the dominant phyla were Proteobacteria (45.9%) and Firmicutes (27.6%), the most abundant genera included Acinetobacter,...

Autores: Brenha-Nunes,Marina R.; Contente,Riguel F.; Rossi-Wongtschowski,Carmen L.D.B.
ABSTRACT We present a protocol for measuring spatial variables in large (&gt;50 m2) soft-sediment tide pool. Secondarily, we present the fish capture efficiency of a sampling protocol that based on such spatial variables to calculate relative abundances. The area of the pool is estimated by summing areas of basic geometric forms; the depth, by taken representative measurements of the depth variability of each pool's sector, previously determined according to its perimeter; and the volume, by considering the pool as a prism. These procedures were a trade-off between the acquisition of reliable estimates and the minimization of both the cost of operating and the time spent in field. The fish sampling protocol is based on two con secutive stages: 1) two...

A pulsatile flow model for in vitro quantitative evaluation of prosthetic valve regurgitation
Provedor de dados: 56
Autores: Giuliatti,S.; Gallo Jr.,L.; Almeida-Filho,O.C.; Schmidt,A.; Marin-Neto,J.A.; Pelá,C.A.; Maciel,B.C.
A pulsatile pressure-flow model was developed for in vitro quantitative color Doppler flow mapping studies of valvular regurgitation. The flow through the system was generated by a piston which was driven by stepper motors controlled by a computer. The piston was connected to acrylic chambers designed to simulate "ventricular" and "atrial" heart chambers. Inside the "ventricular" chamber, a prosthetic heart valve was placed at the inflow connection with the "atrial" chamber while another prosthetic valve was positioned at the outflow connection with flexible tubes, elastic balloons and a reservoir arranged to mimic the peripheral circulation. The flow model was filled with a 0.25% corn starch/water suspension to improve Doppler imaging. A continuous flow...

The Philadelphia chromosome is observed in 5% of pediatric acute lymphocytic leukemia (ALL) and in 25% to 50% of adult ALL cases, and is associated with poor prognosis. Double Ph in a hyperdiploid karyotype is common in chronic myeloid leukemia (CML), but rarely found in ALL. We report here the case of a girl diagnosed with ALL at 7 years of age. After treatment with the pediatric protocol BFM 83 for ALL, she stayed in continuous complete remission for nine years. At age 19, she was re-admitted with a white blood cell count of 6.8 x 10(9)/L with 3% blasts, and a platelet count of 65 x 109/L. Bone marrow aspirate showed 92.6% lymphoid blast cells, and chromosome analysis after G-banding revealed the karyotype...

Due to failures of infection after mechanical inoculation of begomovirus on tomato (Lycopersicon esculentum Mill.) plants, an efficient and reliable begomovirus inoculation method was developed using the whitefly vector (Bemisia tabaci). Virus acquisition was carried out using a 'Tube-cage', made of a polypropylene tube, containing one to two day-old whiteflies and a tomato plant apex infected with a begomovirus isolate. After 48 h of acquisition access period, inoculation was done using a 'Ring-cage', containing viruliferous whiteflies, attached to the abaxial side of the leaf of young tomato plants. 48 hours after acquisition, the whiteflies were eliminated and the inoculated plants were incubated for 28 days under greenhouse conditions.

A single-step purification of bothropstoxin-1
Provedor de dados: 56
Autores: Spencer,P.J.; Aird,S.D.; Boni-Mitake,M.; Nascimento,N.; Rogero,J.R.
Bothrops venoms are complex mixtures of components with a wide range of biological activities. Among these substances, myotoxins have been investigated by several groups. Bothropstoxin-1 (Bthtx-1) is a phospholipase A2-like basic myotoxin from Bothrops jararacussu. The purification of this component involves two chromatographic steps. Although providing a pure material, the association of these two steps is time consuming and a single-step method using high performance chromatography media would be useful. In the present study, we describe a single-step purification method for Bthtx-1. Bothrops jararacussu venom was dissolved in 1 ml buffer. After centrifugation, the supernatant was injected into a Resource-S cation exchange column connected to an FPLC...

A spontaneous body color mutation in Drosophila nappae (Diptera, Drosophilidae)
Provedor de dados: 92
Autores: Rampasso,Augusto Santos; Vilela,Carlos Ribeiro.
ABSTRACT A yellow-bodied male appeared spontaneously in an isofemale line of Drosophila nappae established from a wild-caught female collected at the Forest Reserve of the Instituto de Biociências da Universidade de São Paulo, Cidade Universitária "Armando de Salles Oliveira", São Paulo city, state of São Paulo, Brazil. This is the first mutation found in D. nappae, a species belonging to the tripunctata group. The yellow male was isolated and individually crossed to two wild-type (brown-colored) virgin females from the same generation, yielding numerous offspring. All F1 individuals were wild-type, but the phenotypes yielded in the F2 generation were wild-type females, and both wild-type and yellow-bodied males. The latter yellow male mutants backcrossed...

A strategy for obtaining social benefits from the gene revolution
Provedor de dados: 56
Autores: Castro,L.A.B. de.
The strategy described in the present paper offers details about the possibility for Brazil to play a more substantial role in the gene revolution. If successfully applied, the powerful science-based technology currently available in Brazil can contribute to extend the benefits of the gene revolution to the poorest countries, very much like the Green Revolution did in the past, thereby reducing the hunger syndrome which claimed the lives of millions of people in some Asian countries, particularly Pakistan and India, decades ago. In his visit to Brazil in February 2004, Norman Borlaug had the opportunity to witness the success of Brazilian agriculture. At a Conference held at ESALQ - Superior School of Agriculture Luiz de Queiroz in Piracicaba, SP, Brazil,...

Podemos imaginar agora uma pedra, não muito grande e arredondada, atirada de longe por alguém no meio de suas águas calmas. Que esta seja uma metáfora proveitosa a um convite a pensar as dimensões de algumas possíveis respostas à dupla pergunta: "a quem dirijo o que pesquiso e quem lê o que eu escrevo?". Entre a solidão da pedra em seu vôo antes de cair nas águas, e as ondas concêntricas que ela criará ao mergulhar até o fundo do rio, podemos desenhar uma seqüência de círculos de interlocutores de documentos de original vocação...

Autores: Gonzalez,T.P.; Mucenic,T.; Brenol,J.C.T.; Xavier,R.M.; Schiengold,M.; Chies,J.A.B.
P-glycoprotein (Pgp), the ABCB1 gene product, acts as an efflux pump that transports a large variety of substrates and is a mechanism of cell protection against xenobiotics. An increasing number of studies have shown that some ABCB1 polymorphisms may affect Pgp expression and activity, as well as affecting the development and susceptibility to diseases and pharmacological response. High activity of Pgp has been detected in systemic lupus erythematosus (SLE) patients. The C1236T, G2677T/A, and C3435T are the most commonly studied single nucleotide polymorphisms in the ABCB1 gene. Therefore, their frequencies were determined in Brazilian individuals with European ancestry (N = 143) and in SLE patients (N = 137). Genotyping was performed by PCR-RFLP analysis...

Autores: Carvalho,Nayara; Raizer,Josué; de Aquino Ribas,Augusto Cesar; Delatorre,Milena.
Aranhas caçando sobre flores podem mudar o comportamento de polinizadores e, em consequência, alterar o sucesso reprodutivo das plantas. No entanto, ainda não é perfeitamente conhecido como diferentes grupos de polinizadores reagem à presença de aranhas e em quais circunstâncias ocorre redução no sucesso das plantas. Neste estudo, avaliamos a frequência de visitas florais e o comportamento de abelhas Apis mellifera L. (Apidae) frente ao risco de predação simulado por modelos de aranhas feitos de resina epóxi. A presença destes modelos reduziu o número de visitas em flores de macrófitas aquáticas Ludwigia tomentosa (Cambess.) (Onagraceae) e aumentou a proporção de comportamentos de refugo, em que as abelhas abandonavam repentinamente as flores sem acessar...

Abstract The purpose of this study was to assess the risk of abnormal anal cytology in women with known genital squamous intraepithelial lesion. This study evaluated 200 women with and without genital squamous intraepithelial lesion who were recruited for anal Pap smears. Women who had abnormal results on equally or over atypical squamous cells of undetermined significance were classified as having abnormal anal cytology. A multiple logistic regression analysis (stepwise) was performed to identify the risk for developing abnormal anal cytology. Data were analyzed using the SPSS 20.0 program. The average age was 41.09 (±12.64). Of the total participants, 75.5% did not practice anal sex, 91% did not have HPV-infected partners, 92% did not have any anal...

Autores: Vargas,A.M.; Barros,R.P.A.; Zampieri,R.A.; Okamoto,M.M.; de Carvalho Papa,P.; Machado,U.F.
The GLUT4 transporter plays a key role in insulin-induced glucose uptake, which is impaired in insulin resistance. The objective of the present study was to investigate the tissue content and the subcellular distribution of GLUT4 protein in 4- to 12-year-old control, obese and insulin-treated diabetic mongrel female dogs (4 animals per group). The parametrial white adipose tissue was sampled and processed to obtain both plasma membrane and microsome subcellular fractions for GLUT4 analysis by Western blotting. There was no significant difference in glycemia and insulinemia between control and obese animals. Diabetic dogs showed hyperglycemia (369.9 ± 89.9 mg/dl). Compared to control, the plasma membrane GLUT4, reported per g tissue, was reduced by 55% (P...

ABSTRACT Seed germination is an important step for plants without vegetative propagation and is a physiological process that begins with specific environmental cues resulting in biochemical responses. Breaking-dormancy is necessary to study germination in dormant seeds with asynchronous germination. We investigated the processes of breaking dormancy and germination of Butia capitata (Arecaceae) seeds, in which germination is slow and asynchronous, by operculum removal. This treatment increased germination of B. capitata to 90 %. Embryos of dry, imbibed, 24-hours post-operculum removal and early-germinated seeds were collected for biochemical analysis of the following: quantification of abscisic acid (ABA) and hydrogen peroxide (H2O2), activities of...

Occult hepatitis B virus (HBV) infection has been reported as cases in which HBV DNA was detected despite the absence of any HBV serological markers or in cases in which anti-HBc antibody was the sole marker. The aim of the present study was to determine, using the polymerase chain reaction (PCR), whether HBV infection occurs in hepatitis C and non-A-E hepatitis patients without serological evidence of hepatitis B infection in São Paulo State. Two different populations were analyzed: 1) non-A-E hepatitis patients, including 12 patients with acute and 50 patients with chronic hepatic disorders without serological evidence of infection with known hepatitis viruses; 2) 43 patients previously diagnosed as hepatitis C with positive results for anti-HCV and HCV...

Butyrylcholinesterase (BChE; EC 3.1.1.8; Online Mendelian Inheritance in Man (OMIM) number 177400) is an enzyme found in many human tissues and encoded by the BCHE gene, of which 65 variants have been identified. In a recent study we found that the -116A variant of exon 1 of the BCHE gene was associated with lower mean BChE activity. The present study analyzed the -116 single nucleotide polymorphism (SNP) in 253 Guarani Amerindian Brazilians from the state of Mato Grosso do Sul (148 Guarani-Kaiowá, 83 Guarani-Ñandeva and 22 Kaiowá-Ñandeva descendants) and verified that they were all homozygotic for the -116G variant. A comparative analysis of the -116 site in nine vertebrate species indicated the -116A variant as the ancestral type. This is the first study...

Absence of the A4 peptide in the G4 glycinin subunit of soybean cultivar Enrei is caused by a point mutation in the Gy4 gene
Provedor de dados: 74
Autores: Yu,Kangfu; Poysa,Vaino; Haffner,Margaret; Zhang,Bailing; Woodrow,Lorna.
Functional properties of soy proteins for food are closely related to the composition of their storage protein subunits. Using base excision sequence scanning (BESS), we show that the absence of the A4 peptide in the G4 glycinin subunit of the soybean (Glycine max L.) cultivar Enrei was caused by the same point mutation in the Gy4 gene as previously reported in the soybean cultivar Raiden. Although the genetic relationship between Raiden and Enrei is not known, the same point mutation in their Gy4 genes may indicate that they probably share a related origin. The application of BESS to identify single nucleotide polymorphisms (SNPs) as co-dominant markers for marker-assisted selection (MAS) of a recessive null allele is also discussed.

Academic writing, and how to write in a clear and comprehensible way
Provedor de dados: 63
Autores: Kozak,Marcin.
ABSTRACT An intrinsic part of our lives as scientists, academic writing strongly affects our careers. Even great researchers are much more likely to be successful if they are also proficient writers. Unfortunately, many researchers prefer long hours spent in the field or laboratory to writing. Often, this is a result of their reluctance towards writing, something that characterizes not only scientists, but many people in general. But many researchers do not like writing because they do not know how to do it well—academic writing is not that simple. In this paper, I show how to improve your academic writing skills. I do not teach writing; instead, I share my experience about learning how to write.

Acción de los anticuerpos antifosfolípidos sobre los mecanismos inhibitorios del factor X activado: Posible mecanismo fisiopatológico del síndrome antifosfolípido
Provedor de dados: 38
Autores: Forastiero,Ricardo Raúl; Martinuzzo,Marta Elba.
El síndrome antifosfolípido es una enfermedad autoinmunológica que se define por la presencia de anticuerpos antifosfolìpidos (aFL) en el plasma de pacientes con complicaciones trombóticas tanto en territorio venoso como arterial y/o con morbilidad obstétrica. Los mecanismos patogénicos que han sido propuestos para los aFL se pueden agrupar en dos categorías: 1) efectos inhibitorios sobre los sistemas antitrombóticos fisiológicos y 2) efectos que conducen a la activación celular. En esta revisión se presentan los datos de la acción de los aFL sobre los mecanismos inhibitorios del factor X activado, especialmente lo relacionado al sistema del inhibidor de la vía del factor tisular y del sistema proteína Z e inhibidor de proteasas dependiente de proteína Z.

Accuracy of replication in the polymerase chain reaction. Comparison between Thermotoga maritima DNA polymerase and Thermus aquaticus DNA polymerase
Provedor de dados: 56
Autores: Diaz,R.S.; Sabino,E.C.
For certain applications of the polymerase chain reaction (PCR), it may be necessary to consider the accuracy of replication. The breakthrough that made PCR user friendly was the commercialization of Thermus aquaticus (Taq) DNA polymerase, an enzyme that would survive the high temperatures needed for DNA denaturation. The development of enzymes with an inherent 3' to 5' exonuclease proofreading activity, lacking in Taq polymerase, would be an improvement when higher fidelity is needed. We used the forward mutation assay to compare the fidelity of Taq polymerase and Thermotoga maritima (ULTMA™) DNA polymerase, an enzyme that does have proofreading activity. We did not find significant differences in the fidelity of either enzyme, even when using optimal...

RESUMO O objetivo desta pesquisa foi avaliar o tempo de ação do Lactobacillus plantarum no trato intestinal, assim como em qual frequência esse probiótico deve ser oferecido para tilápia-do-nilo (Oreochomis niloticus). Quarenta e oito tilápias foram alimentadas com ou sem probiótico, durante 14 dias. Após esse período, os peixes foram esviscerados, e amostras do trato intestinal foram semeadas em ágar TCBS, cetrimide e MRS. Esse procedimento foi repetido dois, quatro e seis dias após o 14º dia. Depois disso, 252 tilápias foram divididas em quatro tratamentos, peixes alimentados com probiótico suplementado em 100%, 50%, 25% e 0% (controle) das alimentações. Após nove semanas, os índices zootécnicos foram avaliados. No dia zero, verificou-se maior...

The effects of schistosomiasis on microsomal enzymes were studied on post-infection day 90 when accumulated damage and fibrosis are most intense but granulomatous reaction around the eggs harbored in the liver is smaller than during the earlier phases. Swiss Webster (SW) and DBA/2 mice of either sex (N = 12 per sex per group) were infected with 100 Schistosoma mansoni cercariae on postnatal day 10 and killed on post-infection day 90. Cytochrome P-450 (CYP) concentration and alkoxyresorufin-O-dealkylases (EROD, MROD, BROD, and PROD), p-nitrophenol-hydroxylase (PNPH), coumarin-7-hydroxylase (COH), and UDP-glucuronosyltransferase (UGT) activities were measured in hepatic microsomes. Age-matched mice of the same sex and strain were used as controls. In S....

As semeadoras-adubadoras à taxa variável (TV) estão presentes em estudos focados em atributos do sistema de produção, fazendo com que o conhecimento desenvolvido acerca da qualidade da dosagem dessas máquinas esteja ainda incipiente. No entanto, os dados disponíveis podem ser utilizados para aprofundar a discussão da acurácia, que é o erro percentual entre a dose planejada e a obtida. Dessa maneira, procedeu-se a uma avaliação a partir da meta-análise de dados das publicações oficiais, qualificando a acurácia da dosagem de sementes em diferentes culturas. Dentre os experimentos disponíveis, apenas em um caso a acurácia manteve-se abaixo do valor máximo recomendado de 3%; com operação estável e sem tendências de distorção da dosagem ao longo das densidades...

Autores: Farah,V.M.A.; Moreira,E.D.; Ushizima,M.; Cestari,I.A.; Irigoyen,M.C.; Krieger,E.M.
To assess the role of angiotensin II in the sensitivity of the baroreflex control of heart rate (HR) in normotensive rats (N = 6) and chronically hypertensive rats (1K1C, 2 months, N = 7), reflex changes of HR were evaluated before and after (15 min) the administration of a selective angiotensin II receptor antagonist (losartan, 10 mg/kg, iv). Baseline values of mean arterial pressure (MAP) were higher in hypertensive rats (195 ± 6 mmHg) than in normotensive rats (110 ± 2 mmHg). Losartan administration promoted a decrease in MAP only in hypertensive rats (16%), with no changes in HR. During the control period, the sensitivity of the bradycardic and tachycardic responses to acute MAP changes were depressed in hypertensive rats (~70% and ~65%, respectively)...

Acute buspirone abolishes the expression of behavioral dopaminergic supersensitivity in mice
Provedor de dados: 56
Autores: Queiroz,C.M.T.; Alcântara,F.B.; Yagüe,A.M.L.; Bibancos,T.; Frussa-Filho,R.
Previous studies have shown that rats withdrawn from long-term treatment with dopamine receptor blockers exhibit dopaminergic supersensitivity, which can be behaviorally evaluated by enhanced general activity observed in an open-field. Recently, it has been reported that co-treatment with the non-benzodiazepine anxiolytic buspirone attenuates the development of haloperidol-induced dopaminergic supersensitivity measured by open-field behavior of rats. The aims of the present study were: 1) to determine, as previously reported for rats, if mice withdrawn from long-term neuroleptic treatment would also develop dopaminergic supersensitivity using open-field behavior as an experimental paradigm, and 2) to examine if acute buspirone administration would...

Acute effects of selective serotonin reuptake inhibitors on neuroleptic-induced catalepsy in mice
Provedor de dados: 56
Autores: Pires,J.G.P.; Bonikovski,V.; Futuro-Neto,H.A.
Depression found in Parkinson disease (PD) usually responds to selective serotonin reuptake inhibitors (SSRIs). Drugs that modify experimental neuroleptic catalepsy (NC) might affect extrapyramidal symptoms in PD. Therefore, the effects of SSRIs on NC were tested in mice, 26-36 g, separated by sex. Catalepsy was induced with haloperidol (H; 1 mg/kg, ip) and measured at 30-min intervals using a bar test. An SSRI (sertraline, ST; paroxetine, PX; fluoxetine) or vehicle (C) was injected ip 30 min before H. Dunnett's test was used for comparison of means. ST (1-5 mg/kg) or PX (1-5 mg/kg) attenuated NC, with a similar inhibition found in both sexes (5 mg/kg, 180 min: ST - males: 124 ± 10 vs 714 ± 15 s in C; females: 116 ± 10 vs 718 ± 6 s in C; PX - males: 106 ±...

Autores: Ahmed,Muhammad; Azmat,Aisha; Khan,Salahuddin.
ABSTRACT The aim of this study is to investigate the effectiveness of intravenous administration of Berberis vulgaris root bark aqueous extract (BRBD) on the cardiovascular and renal functions of healthy normotensive rats. The different doses of BRBD 1, 10 and 20 mg/kg were administered intravenously (i.v) in normal rats. Blood pressure, diuretic activity and serum renal profile were analyzed. Intravenous injection of BRBD at the different doses of 1, 10 and 20 mg/kg showed a dose-dependent reduction in mean arterial blood pressure (P&lt;0.001). At different doses of 1, 10 and 20 mg/kg, the hypotensive effect remained for more than one hour. Single dose administration of BRBD at doses of 10 and 20 mg/kg caused a significant increase in urine output...

Adaptaciones y contraadaptaciones entre el Tordo Pico Corto (Molothrus rufoaxillaris) y el Tordo Músico (Agelaioides badius)
Provedor de dados: 68
Autores: De Mársico,María Cecilia; Reboreda,Juan Carlos.
Las aves parásitas de cría obligadas explotan el cuidado parental de individuos de otras especies (hospedadores) que crían a la progenie parásita a expensas de su propio éxito reproductivo. Los costos del parasitismo de cría seleccionan defensas antiparasitarias en la pobla­ción hospedadora (i.e., adaptaciones que reducen el impacto del parasitismo). Esto, a su vez, puede favorecer contraadaptaciones en la población parásita, conduciendo a un proceso coevolutivo de tipo "carrera armamentista" entre parásito y hospedador. En este trabajo se revisan las adapta­ciones recíprocas entre un parásito especialista, el Tordo Pico Corto (Molothrus rufoaxillaris), y su principal hospedador, el Tordo Músico (Agelaioides badius). Las defensas del Tordo Músico incluyen...

Addisonia enodis (Vetigastropoda: Lepetelloidea) associated with an elasmobranch egg capsule from the South Atlantic Ocean and the discovery of the species from deep waters off northeastern Brazil
Provedor de dados: 49
Autores: Lima,Silvio Felipe Barbosa; Simone,Luiz Ricardo Lopes; Guimarães,Carmen Regina Parisotto.
Abstract A gastropod specimen of the subfamily Addisoniinae Dall, 1882 is reported here for the first time associated with an elasmobranch egg capsule from the South Atlantic Ocean. A specimen of Addisonia enodis Simone, 1996 was found living inside an egg capsule of Atlantoraja castelnaui (Miranda Ribeiro, 1907) (Arhynchobatidae Fowler, 1934) from shallow waters off southeastern Brazil. Previous studies have reported the association of members of the genus Addisonia Dall, 1882 only with the egg capsules of sharks from the family Scyliorhinidae Gill, 1862 and skates from the family Rajidae de Blainville, 1816. Other specimens of A. enodis are also here reported to occur off northeastern Brazil based on shells found in deep waters off the state of Sergipe,...

RESUMO Em seres humanos, a adiponectinemia está associada à obesidade e ao risco aumentado a uma ampla variedade de cânceres. Embora o papel dessa adipocina esteja bem documentado na patogênese do câncer em humanos, tal associação permanece a ser determinada em cães. Nesses animais, a relação da adiponectina com a carcinogênese parece ser ainda meramente especulativa. Nesse contexto, buscou-se nesta investigação comparar os níveis séricos de adiponectina em fêmeas hígidas e em portadoras de carcinomas mamários com diagnóstico histopatológico de carcinoma mamário tubular simples estágio 4, com comprometimento de linfonodos, porém sem metástases a distância detectadas. Foi observado que as cadelas diagnosticadas com carcinoma mamário tiveram níveis séricos...

Adiponectina: una adipocitoquina con múltiples funciones protectoras
Provedor de dados: 38
Autores: Elissondo,Natalia; Gómez Rosso,Leonardo; Maidana,Patricia; Brites,Fernando.
Actualmente, se considera que el tejido adiposo es un órgano dinámico involucrado en muchos procesos fisiológicos y metabólicos. Expresa y secreta una gran variedad de péptidos activos conocidos como adipocitoquinas que actúan en forma local y sistémica. Además, expresa numerosos receptores que le permiten responder a señales aferentes de diferentes órganos endocrinos y del sistema nervioso central. La adiponectina es una hormona de 30 kDa producida exclusivamente por el tejido adiposo. A diferencia de las demás adipocitoquinas conocidas, sus niveles se encuentran disminuídos en estados asociados con resistencia insulínica, tal como obesidad, diabetes tipo 2 y síndrome metabólico. A esta proteína se le ha atribuído un rol antidiabético, antiinflamatorio y...

Os metais pesados podem ser encontrados naturalmente em solos, em baixas concentrações, podendo ter seus teores intensificados por meio de ações antrópicas, tornando-se um dos entraves no manejo de solos tropicais. Esses elementos químicos podem ser encontrados na constituição de adubos orgânicos e inorgânicos, inseticidas, fungicidas, rejeito de mineração e lixo urbano, podendo causar sérios danos ao ambiente e à saúde humana. Nesse sentido, estudos de adsorção são imprescindíveis na avaliação do comportamento de metais pesados no solo. O objetivo deste trabalho foi avaliar a influência dos atributos químicos, granulométricos e mineralógicos sobre a adsorção de Cd, avaliados pelos modelos de Langmuir e de Freundlich, em Latossolos que sofreram ou não ação...

Advertisement and courtship calls of Dendropsophus nanus (Boulenger, 1889) (Anura: Hylidae) from its type locality (Resistencia, Argentina)
Provedor de dados: 49
Autores: Teixeira,Bernardo Franco da Veiga; Zaracho,Víctor Hugo; Giaretta,Ariovaldo Antonio.
Abstract Dendropsophus nanus was described from Resistencia, Argentina. The species distribution is widespread in South America east of the Andes. Despite its wide distribution, little information about its advertisement call is available in the literature. Call descriptions from type localities are especially important for the resolution of taxonomic issues, as well as for intraspecific comparisons. Herein we describe the advertisement and the male courtship calls of D. nanus from its type locality. The advertisement call of D. nanus is composed of two types of pulsed notes, herein referred to as “note A” (long note) and “note B” (short note), both with similar dominant frequencies, but different durations. The courtship call is formed by notes that are...

Aedes aegypti survival in the presence of Toxorhynchites violaceus (Diptera: Culicidae) fourth instar larvae
Provedor de dados: 103
Autores: Albeny,Daniel S; Martins,Gustavo F; Andrade,Mateus R; Krüger,Rodrigo F; Vilela,Evaldo F.
The mosquito Aedes aegypti (Linnaeus, 1762) is the main vector of dengue and yellow fever viruses. Different methods have been used to control A. aegypti, including chemical and biological tools. However, chemical control can lead to a subsequent increase in the mosquitoes' insecticide resistance, and biological control represents an important method as an alternative to insecticide usage. Larvae from the Toxorhynchites genus (Diptera: Culicidae) are predators of other mosquitoes and represent a potential natural biocontrol agent of A. aegypti larvae. In the present work, A. aegypti larval survival was studied in the presence of the neotropical Toxorhynchites violaceus (Wiedemann, 1821) fourth instar larvae. Toxorhynchites violaceus consumption of A....

Agmatine inhibits hypoxia-induced TNF-alpha release from cultured retinal ganglion cells
Provedor de dados: 47
Autores: Hong,Samin; Park,Kyoungsoo; Kim,Chan Yun; Seong,Gong Je.
The effect of hypoxia on the release of tumor necrosis factor-alpha (TNF-alpha) in transformed rat retinal ganglion cells (RGCs) and the effect of agmatine on the hypoxia-induced production of TNF-alpha in RGCs were evaluated. RGCs were cultured under hypoxic conditions with 5% oxygen, with or without 100&amp;#956;M agmatine. The expression levels of TNF-alpha and its receptor-1 (TNF-R1) were investigated by Western blot analysis. After 6 hours of hypoxia, we noted an increase in TNF-alpha production in RGCs. Agmatine significantly reduced TNF-alpha level after 12 hours of hypoxic treatment. The expression of TNF-R1 was not affected by the hypoxia or agmatine treatment. Our results show that agmatine inhibits the TNF-alpha production of RGCs in hypoxic...

Agricultura, população e dinâmica macroeconômica de municípios rurais: um estudo em Lagoa dos Três Cantos (RS)
Provedor de dados: 123
Autores: Silva Neto,Benedito; Figueiredo,José Wnilson.
Os municípios com menos de 20.000 habitantes do Rio Grande do Sul abrigam mais de um terço da população total do estado. A partir da hipótese de que a distribuição de renda, a população e a dinâmica da agricultura podem desempenhar um papel importante no desenvolvimento desses municípios, foi elaborado um modelo macroeconômico que permitisse analisar a influência desses fatores sobre economias locais. Simulações efetuadas com esse modelo, aplicado a um pequeno município agrícola do norte do estado (Lagoa dos Três Cantos), indicaram que uma distribuição de renda mais equânime associada a uma diversificação da produção provocariam um aumento significativo da demanda de bens e serviços destinados ao consumo interno, com efeitos benéficos sobre o...

Provedor de dados: 74
Autores: Limeira,Daniel M.; Renesto,Erasmo; Zawadzki,Cláudio H.
Two allopatric morphotypes of the genus Rinelocaria were compared through the allozyme electrophoresis technique: one morphotype, R. pentamaculata, from the Keller River in the middle stretch of the Ivaí River basin and the other, R. aff. pentamaculata, from the São João River in the upper portion of the Ivaí River basin. The morphotype from the São João River was collected upstream from the São João waterfall, which is about 80 m deep. Twelve enzymatic systems (AAT, ADH, EST, GCDH, G3PDH, GPI, IDH, LDH, MDH, ME, PGM and SOD) were analyzed, which allowed to score 22 loci. Only loci Aat-2, Est-3 and Mdh-C showed polymorphism. The two samples differed in allele frequencies at the three polymorphic loci. The average expected heterozygosity for all loci was...

This study aimed to evaluate the extract of Aloe vera (AV) associated or not with 10% Dimethylsulfoxide (DMSO) in cryopreservation of tambaqui semen. For the formation of the pools (n= 14), 30 males were hormonally induced twice. Each pool had the objective motility, curvilinear velocity, straight-line velocity, average path velocity and morphology analyzed before and after cryopreservation of semen. The means for cryopreservation were constituted of Powder Coconut Water-104 diluent added DMSO and/or AV (5 or 10%). After cryopreservation, motility, velocities and morphology were reduced significantly when compared to fresh semen. For sperm motility the best treatment was that using only DMSO (20,86±8,31) and DMSO + 5% AV (15.71±9.77). For the velocities,...

Aluminum induces lipid peroxidation and aggregation of human blood platelets
Provedor de dados: 56
Aluminum (Al3+) intoxication is thought to play a major role in the development of Alzheimer's disease and in certain pathologic manifestations arising from long-term hemodialysis. Although the metal does not present redox capacity, it can stimulate tissue lipid peroxidation in animal models. Furthermore, in vitro studies have revealed that the fluoroaluminate complex induces diacylglycerol formation, 43-kDa protein phosphorylation and aggregation. Based on these observations, we postulated that Al3+-induced blood platelet aggregation was mediated by lipid peroxidation. Using chemiluminescence (CL) of luminol as an index of total lipid peroxidation capacity, we established a correlation between lipid peroxidation capacity and platelet aggregation. Al3+...

Amino acid composition of parturient plasma, the intervillous space of the placenta and the umbilical vein of term newborn infants
Provedor de dados: 56
Autores: Camelo Jr.,J.S.; Jorge,S.M.; Martinez,F.E.
The objective of the present study was to determine the levels of amino acids in maternal plasma, placental intervillous space and fetal umbilical vein in order to identify the similarities and differences in amino acid levels in these compartments of 15 term newborns from normal pregnancies and deliveries. All amino acids, except tryptophan, were present in at least 186% higher concentrations in the intervillous space than in maternal venous blood, with the difference being statistically significant. This result contradicted the initial hypothesis of the study that the plasma amino acid levels in the placental intervillous space should be similar to those of maternal plasma. When the maternal venous compartment was compared with the umbilical vein, we...

Provedor de dados: 74
Autores: Sastre,Darío A.; Argaraña,Carlos E.; Heller,Viviana B.; Gallo,Mónica; Fernández,Enrique N.; Rodríguez,Cecilia M.
In this work, we describe the advantages of multiplex-PCR in the specific detection of BCR-ABL transcripts in different hematological disorders and its sensitivity compared to nested PCR. Fifty-three patients were studied for the presence of BCR-ABL transcripts: 24 patients with chronic myeloid leukemia (CML), 20 with acute leukemia (AL), and 9 patients with other hematological disorders. A variant rearrangement (b3a3) was found in a single case of CML (4.2%). Four out of the 20 patients with AL (20.0%) (14 adults, 6 children) were bcr-abl(+), and in this group three cases were classified as B-acute lymphoblastic leukemia (B-ALL), and one as acute myeloblastic leukemia (AML). Two of the three patients with B-ALL were positive for b2a2 and the other one for...

Autores: Fontenelle,L.F.; Mendlowicz,M.V.; Moreira,R.O.; Appolinario,J.C.
The International Classification of Diseases, 10th edition (ICD-10) defines atypical bulimia nervosa (ABN) as an eating disorder that encompasses several different syndromes, including the DSM-IV binge eating disorder (BED). We investigated whether patients with BED can be differentiated clinically from patients with ABN who do not meet criteria for BED. Fifty-three obese patients were examined using the Structured Clinical Interview for DSM-IV and the ICD-10 criteria for eating disorders. All volunteers completed the Binge Eating Scale (BES), the Beck Depression Inventory, and the Symptom Checklist-90 (SCL-90). Individuals fulfilling criteria for both ABN and BED (N = 18), ABN without BED (N = 16), and obese controls (N = 19) were compared and contrasted....

An improved in vivo method for atrioventricular node ablation via thoracotomy
Provedor de dados: 56
Autores: MacIver,R.H.; Stewart,R.D.; Backer,C.L.; Tsao,S.; Harrington,D.A.; Mavroudis,C.
The atrioventricular (AV) node is permanently damaged in approximately 3% of congenital heart surgery operations, requiring implantation of a permanent pacemaker. Improvements in pacemaker design and in alternative treatment modalities require an effective in vivo model of complete heart block (CHB) before testing can be performed in humans. Such a model should enable accurate, reliable, and detectable induction of the surgical pathology. Through our laboratory’s efforts in developing a tissue engineering therapy for CHB, we describe here an improved in vivo model for inducing chronic AV block. The method employs a right thoracotomy in the adult rabbit, from which the right atrial appendage may be retracted to expose an access channel for the AV node. A...

AN in vivo METHOD FOR ESTIMATING THE CONCENTRATION OF CROTAMINE IN A SOLUTION
Provedor de dados: 79
Autores: HAMPE,O. G.; BELLÓ,A. A.
very sensitive method for estimating the concentration of crotamine in a solution was developed. This method was based on the time required for the appearance of permanent hyperextension of the rear legs of mice as a function of the dose administered. This method can be used to determine toxin doses as low as 0.32 mg/kg&lt;img SRC="http:/img/fbpe/jvat/v3n1/image2875.gif"&gt; . Its high specificity for crotamine means that it can be used to measure toxin concentrations in the presence of other proteins and polypeptides.

An MD-PhD program in Brazil: students’ concepts of science and of common sense
Provedor de dados: 56
Autores: Oliveira,R.V.; Campos,P.C.C.; Mourão,P.A.S.
In 1995, a pioneering MD-PhD program was initiated in Brazil for the training of medical scientists in experimental sciences at the Federal University of Rio de Janeiro. The program’s aim was achieved with respect to publication of theses in the form of papers with international visibility and also in terms of fostering the scientific careers of the graduates. The expansion of this type of program is one of the strategies for improving the preparation of biomedical researchers in Brazil. A noteworthy absence of interest in carrying out clinical research limits the ability of young Brazilian physicians to solve biomedical problems. To understand the students’ views of science, we used qualitative and quantitative triangulation methods, as well as...

An optically coupled power stimulus isolation unit with high voltage and fast rise time output
Provedor de dados: 56
Autores: Brasil,R.O.; Leal-Cardoso,J.H.
Recent technological developments have created new devices that could improve and simplify the construction of stimulus isolators. HEXFET transistors can switch large currents and hundreds of volts in nanoseconds. The newer opto-isolators can give a pulse rise time of a few nanoseconds, with output compatible with MOSFET devices, in which delays are reduced to nanoseconds. Integrated DC/DC converters are now available. Using these new resources we developed a new electrical stimulus isolator circuit with selectable constant-current and constant-voltage modes, which are precise and easy to construct. The circuit works like a regulated power supply in both modes with output switched to zero or to free mode through an opto-isolator device. The isolator...

An unusual reproductive mode in Hypsiboas (Anura: Hylidae)
Provedor de dados: 103
Autores: Moura,Mário Ribeiro de; Motta,Ana Paula; Feio,Renato Neves.
We report an unusual reproductive behavior of Hypsiboas pardalis (Spix, 1824). Species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles. Herein, the bromeligenous behavior is reported for the first time in Hypsiboas Wagler, 1830. Although this reproductive behavior has been observed more than once here, we believe that it is not typical of Hypsiboas, being better characterized as an unusual reproductive mode for Hypsiboas, indicating the presence of plasticity in the reproductive modes of H. pardalis

Analysis of Africanized honey bee mitochondrial DNA reveals further diversity of origin
Provedor de dados: 74
Autores: Sheppard,Walter S.; Rinderer,Thomas E.; Garnery,Lionel; Shimanuki,Hachiro.
Within the past 40 years, Africanized honey bees spread from Brazil and now occupy most areas habitable by the species Apis mellifera, from Argentina to the southwestern United States. The primary genetic source for Africanized honey bees is believed to be the sub-Saharan honey bee subspecies A. m. scutellata. Mitochondrial markers common in A. m. scutellata have been used to classify Africanized honey bees in population genetic and physiological studies. Assessment of composite mitochondrial haplotypes from Africanized honey bees, using 4 base recognizing restriction enzymes and COI-COII intergenic spacer length polymorphism, provided evidence for a more diverse mitochondrial heritage. Over 25% of the "African" mtDNA found in Africanized populations in...

Provedor de dados: 56
Autores: Duch,C.R.; Figueiredo,M.S.; Ribas,C.; Almeida,M.S.S.; Colleoni,G.W.B.; Bordin,J.O.
It is well established that interleukin-6 (IL-6) is an essential growth factor for multiple myeloma (MM) and patients with increased IL-6 levels have a poor prognosis. In healthy subjects, the presence of the C allele at a polymorphic site (-174 G/C) of the IL-6 gene is related to low IL-6 levels. In view of the potential association of this particular polymorphism with IL-6 concentration, and the relevance of IL-6 in MM pathogenesis, the objective of the present study was to investigate the prevalence of IL-6 (-174 G/C) promoter polymorphism and its association with development of MM in Brazilian individuals. We investigated the prevalence of these alleles in 52 patients and 60 healthy subjects (matched by age, sex, and race) of a Brazilian population....

Autores: Scavone,Márcia Denise da Paixão; Oliveira,Claudio; Bagagli,Eduardo; Foresti,Fausto.
The synaptonemal complex (SC) of three specimens of the nine-banded armadillo (Dasypus novemcinctus) was analyzed. Thirty-two bivalents (2n = 64) were observed, 31 of them being autosomes and one an XY sexual bivalent. Chromosome synapsis processes and nucleolus structure changes were analyzed in zygotene and pachytene cells, allowing a detailed description of the beginning of meiotic prophase in this species. There was complete synapsis of X and Y chromosomes. Some abnormalities in SC were observed in cells during zygotene and at the beginning of pachytene, but not in cells in the middle and late pachytene, suggesting the occurrence of synaptic adjustments in their SC.

There are often discrepancies when using different methods to measure anti-Toxoplasma gondii IgG levels in patient samples. The diagnostic performance of a chemiluminescent immunoassay (CLIA) and an enzyme-linked fluorescent assay (ELFA) used as confirmatory tests for samples identified as positive or equivocal by an electrochemiluminescent immunoassay (ECLIA) were examined. Cut-off values were those stated by the manufacturer, and Western blot was used to confirm the results of all methods. All samples identified as positive by ECLIA (n = 93) were confirmed as positive by Western blot, as were 14 of the 28 samples identified as equivocal. When these 121 samples were retested, the sensitivities of CLIA and ELFA were 64.4% and 73.8%, respectively. Both...

Bradykinin has been reported to act as a growth factor for fibroblasts, mesangial cells and keratinocytes. Recently, we reported that bradykinin augments liver regeneration after partial hepatectomy in rats. Angiotensin-converting enzyme (ACE) is also a powerful bradykinin-degrading enzyme. We have investigated the effect of ACE inhibition by lisinopril on liver regeneration after partial hepatectomy. Adult male Wistar rats underwent 70% partial hepatectomy (PH). The animals received lisinopril at a dose of 1 mg kg body weight-1 day-1, or saline solution, intraperitoneally, for 5 days before hepatectomy, and daily after surgery. Four to six animals from the lisinopril and saline groups were sacrificed at 12, 24, 36, 48, 72, and 120 h after PH. Liver...

Anhydrobiosis in yeast: activation effect
Provedor de dados: 56
Intracellular substances released into the medium during rehydration of dry yeast cells can significantly improve the quality of a synthetic medium. Acceleration of yeast growth in this medium and increased yield of biomass are observed simultaneously. The change in the molecular arrangement of intracellular membranes as a result of the strong dehydration of live organisms is a negative phenomenon that reduces the level of cell viability. However, this phenomenon also represents an adaptive mechanism which facilitates the maintenance of population viability as a whole under extreme environmental conditions

Animal models of anxiety: an ethological perspective
Provedor de dados: 56
In the field of anxiety research, animal models are used as screening tools in the search for compounds with therapeutic potential and as simulations for research on mechanisms underlying emotional behaviour. However, a solely pharmacological approach to the validation of such tests has resulted in distinct problems with their applicability to systems other than those involving the benzodiazepine/GABAA receptor complex. In this context, recent developments in our understanding of mammalian defensive behaviour have not only prompted the development of new models but also attempts to refine existing ones. The present review focuses on the application of ethological techniques to one of the most widely used animal models of anxiety, the elevated plus-maze...

Autores: Silveira,Silvaldo F.; Harrington,Thomas C.; Mussi-Dias,Vicente; Engelbrecht,Christine J. B.; Alfenas,Acelino C.; Silva,Carolina R.
Mango branch blight disease, caused by Ceratocystis fimbriata, is endemic to the municipality of São Fidelis in northern Rio de Janeiro State. In addition to mango, C. fimbriata was found associated with sugar apple trees (Annona squamosa) showing symptoms of branch blight in São Fidelis. Sugar apple and mango isolates from the same region had the same morphology and showed similar ITS-rDNA sequences. These sequences were also similar to other Brazilian isolates of C. fimbriata sensu stricto. Cross inoculation of such isolates obtained from diseased sugar apple and mango resulted in diseased symptoms on both plant species. This is the first record of A. squamosa as a host for C. fimbriata.

Annual changes in a bird assembly on artificial perches: Implications for ecological restoration in a subtropical agroecosystem
Provedor de dados: 49
Autores: Vogel,Huilquer Francisco; Spotswood,Erica; Campos,João Batista; Bechara,Fernando Campanhã.
Artificial perches are used in tropical forest restoration projects to increase the dispersal of seeds into restored areas. The ability of perches to enhance seed deposition depends on their ability to attract seed dispersing birds, as well as the correlation between the season of bird visits to perches and the phenology of fruit production in adjacent forests. Using data collected from a large-scale restoration project, we characterized the community of birds that utilize artificial perches over the course of one year. We hypothesized that the structure of a bird assemblage that uses artificial perches is affected by seasonal variation. We aimed to describe the richness, abundance and diversity of a bird assemblage on artificial perches in a subtropical...

Ant fauna associated with Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae) fern galls
Provedor de dados: 92
Autores: Santos,Marcelo Guerra; Porto,Gabriela Fraga; Lancellotti,Isabella Rodrigues; Feitosa,Rodrigo M.
Abstract Galls are neoformed plant structures created by cell hyperplasia and hypertrophy induced by a number of organisms, especially insects. After adult insects hatch, senescent galls may remain on the host plant and be occupied by a succession of fauna, the most important and dominant being ants. This study aimed at characterizing the ant fauna successor of stem galls induced by microlepidoptera in Microgramma squamulosa (Kaulf.) de la Sota (Polypodiaceae). Four collections were carried out in the municipality of Nova Friburgo, Rio de Janeiro state, Brazil. The galls were packed in plastic bags and taken to the laboratory. Ants were euthanized and conserved in 70° GL alcohol and later identified. A total of 49 stem galls were collected and analyzed, 15...

Antagonic effect of the inhibition of inducible nitric oxide on the mortality of mice acutely infected with Escherichia coli and Bacteroides fragilis
Provedor de dados: 56
Autores: Astolfi,R.S.; Khouri,D.G.; Brandizzi,L.I.V.; Ávila-Campos,M.J.; Andrade Jr.,H.F. de.
Sepsis, the leading cause of death in intensive care units, is associated with overproduction of nitric oxide (NO) due to inducible NO synthase (iNOS), responsible for some of the pathologic changes. Aminoguanidine (AG) is a selective iNOS inhibitor with reported inconsistent actions in sepsis. To investigate the influence of iNOS, we studied models of acute bacterial sepsis using acute challenges with aerobic (Escherichia coli) and anaerobic (Bacteroides fragilis) bacteria in the presence of AG. Six-week-old, 23 g, male and female BALB/c and C57Bl/6j mice, in equal proportions, were inoculated (ip) with bacteria in groups of 4 animals for each dose and each experiment in the absence or presence of AG (50 mg/kg, ip, starting 24 h before challenge and daily...

Antagonism by hemoglobin of effects induced by L-arginine in neuromuscular preparations from rats
Provedor de dados: 56
Autores: Ambiel,C.R.; Alves-Do-Prado,Wilson.
Nitric oxide (NO)-synthase is present in diaphragm, phrenic nerve and vascular smooth muscle. It has been shown that the NO precursor L-arginine (L-Arg) at the presynaptic level increases the amplitude of muscular contraction (AMC) and induces tetanic fade when the muscle is indirectly stimulated at low and high frequencies, respectively. However, the precursor in muscle reduces AMC and maximal tetanic fade when the preparations are stimulated directly. In the present study the importance of NO synthesized in different tissues for the L-Arg-induced neuromuscular effects was investigated. Hemoglobin (50 nM) did not produce any neuromuscular effect, but antagonized the increase in AMC and tetanic fade induced by L-Arg (9.4 mM) in rat phrenic nerve-diaphragm...

Five species of edible mushrooms, Lentinula edodes, Pleurotus ostreatus, Pholiota nameko, Macrolepiota bonaerensis and Agaricus blazei, were tested for their potential to inhibit the in vitro growth of the pathogenic yeast Candida albicans. Only L. edodes had a fungistatic effect on this human pathogen. The inhibitory compound was produced intra and extracellularly in submersed L. edodes culture, and was also present in fresh and dehydrated mushroom basidiocarps. The fungistatic compound was heat sensitive and lost activity after 72 hours.

Anterograde effects of a single electroconvulsive shock on inhibitory avoidance and on cued fear conditioning
Provedor de dados: 56
Autores: Oliveira,M.G.M.; Bueno,O.F.A.; Gugliano,E.B.
A single electroconvulsive shock (ECS) or a sham ECS was administered to male 3-4-month-old Wistar rats 1, 2, and 4 h before training in an inhibitory avoidance test and in cued classical fear conditioning (measured by means of freezing time in a new environment). ECS impaired inhibitory avoidance at all times and, at 1 or 2 h before training, reduced freezing time before and after re-presentation of the ECS. These results are interpreted as a transient conditioned stimulus (CS)-induced anxiolytic or analgesic effect lasting about 2 h after a single treatment, in addition to the known amnesic effect of the stimulus. This suggests that the effect of anterograde learning impairment is demonstrated unequivocally only when the analgesic/anxiolytic effect is...

Crematogaster ants use their contact venoms to compete with other ants. Although those venoms are used primarily as repellent and toxic secretions, they may have other functions. The present study aimed to test the antibacterial property of abdominal venom of three neotropical Crematogaster ant species (C. distans, C. pygmaea and C. rochai) against gram-negative (Escherichia coli and Pseudomonas aeruginosa) and gram-positive (Enterococcus faecalis and Staphylococcus aureus) bacteria. Sterile filter paper was soaked with C. distans, C. pygmaea or C. rochai crude venom and placed on an agar dish that was inoculated with bacterial suspensions. The agar dish was incubated overnight at 37ºC and examined for zones of growth inhibition. For each tested venom and...

Autores: Antunes,Lusânia M. Greggi; Darin,Joana D.C.; Bianchi,Maria de Lourdes P.
The ability of vitamin C (VC) to protect against the clastogenic action of the chemotherapeutic agent cisplatin (DDP, cis-diamminedichloroplatinun II) in rat bone marrow cells was evaluated. DDP was administered to Wistar rats either alone or after treatment with VC. The rats were treated with VC (50, 100 or 200 mg/kg body weight) by gavage 10 min before the administration of DDP (5 mg/kg body weight, ip) and then sacrificed 24 h after treatment. VC significantly reduced (by about 70%) the clastogenicity of DDP in rat bone marrow cells. The antioxidant action of VC presumably modulates the clastogenic action of DDP.

Since November 2007 until May 2009, 1,778 serum samples of cattle from dairy herds of the Southwest of Paraná State, Brazil, were used for search of anti-Neospora caninum antibodies. The frequency of seropositive animals, assessed by IFAT, was 24.2% (431/1,178), showing a relatively high occurrence in the studied population. These results show that Neospora caninum is widely distributed in the dairy cattle in the Southwest of Paraná State. The presence of Neospora caninum in a herd is worrisome, since this protozoan is closely related with reproductive disorders and low milk production in cattle.

The prevalence of small ruminant lentivirus (SRL) infection was evaluated in goats and sheep in two counties of Pernambuco State, Brasil. Seriological examinations were performed from a total of 672 goats and 325 sheep, one year of age and older, at two abattoirs. Sera were analyzed by agar gel immunodiffusion using Maedi-Visna K-1514 antigens. There were 42 reactive samples (95% confidence interval 3.6% to 4.9%) in both slaughter houses. In São Lourenço da Mata county, 3.2% and 4.0% of goat and sheep sera were responsive, whereas in Paulista county, 5.1% of goat samples and 8.2% of sheep were reactive. Thus, the prevalence of small ruminant lentivirus was low in goats and sheep sampled from the region.

The occurrence of serum antibodies to Borrelia burgdorferi in professionals in close contact with wild animals was determined. Seventy eight technicians workers coming from two São Paulo public institutions housing wild animals had their blood collected (serum samples). All samples were submitted to ELISA for IgM and IgG antibodies against Borrelia burgdorferi. The results showed five positive (6.4%), two suspect (2.6%) and 71 negatives (91%) samples. Based on positive results it is concluded that the infection level is higher to that detected in the general population and similar to values of endemic areas, concluding that this assessed population could be considered at risk for Lyme disease.

It has been reported that lead can cause behavioral impairment by inhibiting the N-methyl-D-aspartate (NMDA) receptor complex. MK-801, a noncompetitive NMDA receptor antagonist, exhibits an antidepressant-like action in the forced swimming test. The purpose of the present study was to determine whether subacute lead exposure in adult male Swiss mice weighing 30-35 g causes an antidepressant-like action in a forced swimming test. Mice were injected intraperitoneally (ip) with 10 mg/kg lead acetate or saline daily for 7 consecutive days. Twenty-four hours after the last treatment, the saline and lead-treated mice received an injection of MK-801 (0.01 mg/kg, ip) or saline and were tested in forced swimming and in open-field tests.

Autores: Oliveira,R.; Prado,W.A.
Electroacupuncture has been proposed to be a low cost and practical method that allows effective pain management with minimal collateral effects. In this study we have examined the effect of electroacupuncture against the hyperalgesia developed in a model of post-incisional pain in rats. A 1-cm longitudinal incision was made through the skin and fascia of the plantar region of the animal hind paw. Mechanical hyperalgesia in the incision was evaluated 135 min after the surgery with von Frey filaments. The tension threshold was reduced from 75 g (upper limit of the test) to 1.36 ± 0.36 g (mean ± SEM) in control rats. It is shown that a 15-min period of electroacupuncture applied 120 min after surgery to the Zusanli (ST36) and Sanyinjiao (SP6) points, but not...

Anti-inflammatory activity of the apolar extract from the seaweed Galaxaura marginata (Rhodophyta, Nemaliales)
Provedor de dados: 80
Autores: Rozas,E.; Freitas,J. C.
The red seaweed Galaxaura marginata (Ellis &amp;amp; Solander) Lamouroux, well known by the antibacterial activity of its polar extract and the cytotoxic activity of its oxygenated desmosterol, showed anti-inflammatory action in its apolar fraction. Topical anti-inflammatory activity was observed in samples collected at São Sebastião channel, northern littoral of São Paulo State, Brazil. The apolar extract and its fractions obtained through Thin-Layer Chromatography (TLC) reduced the topical inflammation produced by croton oil in mouse ear. Such data indicated that the apolar extract from the marine red alga G. marginata displayed anti-inflammatory activity (since 1mg/ear extract reduced 95±0.5% inflammation), which could be the result of the synergic...

Anti-leishmania antibodies in cerebrospinal fluid from dogs with visceral leishmaniasis
Provedor de dados: 56
Autores: Lima,V.M.F.; Gonçalves,M.E.; Ikeda,F.A.; Luvizotto,M.C.R.; Feitosa,M.M.
Visceral leishmaniasis in Brazil is caused by Leishmania (Leishmania) chagasi and the dog is its most important reservoir. The clinical features in dogs include loss of weight, lymphadenopathy, renal failure, skin lesions, fever, hypergammaglobulinemia, hepatosplenomegaly, anemia, and, rarely, neurological symptoms. Most infected animals develop active disease, characterized by high anti-leishmania antibody titers and depressed lymphoproliferative ability. Antibody production is not primarily important for protection but might be involved in the pathogenesis of tissue lesions. An ELISA test was used to determine if there is an association between neurological symptoms and the presence of anti-L. chagasi antibodies in cerebrospinal fluid (CSF). Thirty serum...

Visceral leishmaniasis (VL), also known as kala-azar, is an important public health problem. If not treated, virtually all clinically symptomatic patients die within months. The diagnosis is based on the Montenegro skin test (MST) and anti-Leishmania titers. Nevertheless, the time required for cured individuals living in a leishmaniasis-endemic area to present a positive skin test and negative anti-Leishmania serology is known. To determine the cellular and humoral immune response profile in relation to different times post-VL cure, a cross-sectional study was conducted on subjects from a kala-azar endemic area in Paço do Lumiar, MA, Brazil, on the basis of 1995-2005 notifications reported by the National Health Foundation/Regional Coordination of...

Provedor de dados: 55
Autores: Frazão,Miliane R.; Andrade,Leonardo N.; Darini,Ana L.C.; Falcão,Juliana P.
Abstract Some studies evaluated the resistance profile of the Y. enterocolitica strains isolated in diverse countries. However, in Brazil the isolation and the study of Y. enterocolitica are not common and therefore information about the antimicrobial resistance profile of this species in this country is scarce. Therefore, the aim of this study was to evaluate the antimicrobial resistance of Y. enterocolitica of biotypes 1A, 2 and 4 isolated from clinical and non-clinical sources between 1979 and 2012, in Brazil. This study showed that some Yersinia enterocolitica of different biotypes remain susceptible to antimicrobials used for gastroenteritis treatment. Moreover, neither acquired resistance genes nor diversity of plasmids replicons were found; however,...

Antimicrobial treatment is often indicated to neutropenic patients. Although renal failure is a common complication of many antibiotics, no information could be found in the literature defining which are the best screening criteria for detecting renal injury. In this paper, the authors aim to assess the progress to renal failure in neutropenic patients on antimicrobial use and to compare different diagnostic criteria of renal failure in association to antimicrobial agents used. This is a cohort study conducted from February to August 2006 at the Hospital das Clínicas of the Universidade Federal de Minas Gerais, which included patients with neutropenia and antimicrobial therapy for the treatment of Healthcare Associated Infections notified by the Hospital...

Anting behavior by the White-bearded Manakin (Manacus manacus, Pipridae): an example of functional interaction in a frugivorous lekking bird
Provedor de dados: 49
Autores: Cestari,César.
Behavioral studies of birds have reported several functions for active anting. Maintenance of plumage and prevention from ectoparasites are some examples. In this context, anting by males may be of particular importance in a classical lek mating system, where male-male competition is common and individuals with higher fitness may be more successful at attracting of females. In the present note, I describe the anting behavior of White-bearded Manakin (Manacus manacus) and I relate it to lek breeding and feeding (frugivory) habits of the species. Males used up to seven Solenopsis sp. ants. They rubbed each small ant from 4 to 31 times on undertail feathers until the ants were degraded; ants were not eaten. Males then searched for a new ant in the court....

Autores: Tabarelli,Z.; Berlese,D.B.; Sauzem,P.D.; Mello,C.F.; Rubin,M.A.
Surfactants are frequently used to improve solubilization of lipophilic drugs. Cremophor EL (CrEL) is a polyoxyethylated castor oil surfactant used to solubilize water-insoluble drugs such as anesthetic, antineoplastic, immunosuppressive and analgesic drugs, vitamins and new synthetic compounds, including potential analgesics. The antinociceptive effect of CrEL (3.2, 6.4 and 10.6 g/kg, in 10 ml/kg body weight, by gavage) on the abdominal writhing response induced by intraperitoneal administration of acetic acid (0.8%, 10 ml/kg body weight) and on the tail immersion test was investigated in mice. Control animals received castor oil (10 ml/kg body weight) or saline (0.9% NaCl, 10 ml/kg body weight). CrEL reduced nociception in a dose-dependent manner in both...

Mentha x villosa Huds (Labiatae) is an aromatic herb widely used in folk medicine. Since the essential oil of the herb has many pharmacological activities, including antispasmodic effects, we determined whether the oil and its major constituent, piperitenone oxide (PO), have antinociceptive activity. The essential oil of M. x villosa (EOMV) and PO administered orally at 200 mg/kg (vehicle: 0.1% Tween 80 in water) significantly reduced the writhings induced by acetic acid from control values of 59.5 ± 3.1 s (N = 10) to 31.9 ± 2.8 s (N = 10) and 23.8 ± 3.4 s (N = 10), respectively. When administered at 100 and 200 mg/kg, EOMV reduced the paw licking time for the second phase of the formalin test from the control value of 20.6 ± 2.1 s (N = 13) to 5.3 ± 2.2 s...

We have investigated the antinociceptive effects of the essential oil of Ocimum gratissimum L. (Labiatae) (EOOG) in two classical models of pain in male Swiss mice (25-35 g), the writhing test and the formalin test. At doses of 30, 100 and 300 mg/kg (po), EOOG produced a dose-dependent inhibition (from 58.3 ± 4.4 to 40.7 ± 6.3, 36.4 ± 3.6 and 24.6 ± 3.6, respectively; N = 8-10, P&lt;0.05) of acetic acid-induced writhing, causing up to a ~60% inhibition at the highest dose used, comparable to that obtained with indomethacin (10 mg/kg, po). At the same doses, EOOG predominantly inhibited the late (inflammatory) phase of the formalin-induced pain response (from 59.3 ± 8.3 to 40.4 ± 4.8, 23.2 ± 2.8 and 25.3 ± 5.5, respectively; N = 6, P&lt;0.05), with a...

Anuran captured in pitfall traps in three agrossystem in Northwestern São Paulo State, Brazil
Provedor de dados: 49
Autores: Silva,Fernando Rodrigues da; Santos,Rodrigo Souza; Nunes,Maria Andréia; Rossa-Feres,Denise de Cerqueira.
Although it is generally assumed that agriculture negatively influences amphibian populations, few studies on the effects of agricultural cultivations on neotropical anuran have been conducted. As a contribution to the knowledge about anuran in agriculture, the present study sought to identify the anuran species present in three different agrossystems. We used data from anurans captured in pitfall traps initially proposed for a survey of harvestmen fauna in three agrossystems (corn, soybean, and rubber tree). Four anuran species found in the pitfall traps belong to two Families: Leptodactylidae: Leptodactulus fuscus and L. mystacinus; and Leiuperidae: Eupemphix nattereri and Physalaemus cuvieri. In corn plantation, four species and 30 individuals were...

Anxiolytic effect of methylene blue microinjected into the dorsal periaqueductal gray matter
Provedor de dados: 56
Autores: de-Oliveira,R.W.; Guimarães,F.S.
The dorsal periaqueductal gray (DPAG) has been implicated in the behavioral and autonomic expression of defensive reactions. Several results suggest that, along with GABA, glutamate and serotonin, nitric oxide (NO) may play a role in defense reactions mediated by this region. To further investigate this possibility we microinjected methylene blue (MB; 10, 30 or 100 nmol/0.5 µl) into the DPAG of rats submitted to the elevated plus-maze test, an animal model of anxiety. MB has been used as an inhibitor of soluble guanylate cyclase (sGC) to demonstrate cGMP-mediated processes, and there is evidence that NO may exert its biological effects by binding to the heme part of guanylate cyclase, causing an increase in cGMP levels. The results showed that MB (30 nmol)...

Anxiolytic effects of repeated treatment with an essential oil from Lippia alba and (R)-(-)-carvone in the elevated T-maze
Provedor de dados: 56
Autores: Hatano,V.Y.; Torricelli,A.S.; Giassi,A.C.C.; Coslope,L.A.; Viana,M.B.
Lippia alba (Mill.) N.E. Brown (Verbenaceae) is widely used in different regions of Central and South America as a tranquilizer. The plant’s anxiolytic properties, however, merit investigation. The present study evaluated the effects of repeated daily (14 days) intraperitoneal (ip) treatment with an essential oil (EO) from a chemotype of L. alba (LA, chemotype II, 12.5 and 25 mg/kg; N = 6-8) and (R)-(-)-carvone (25 mg/kg; N = 8-12), the main constituent of this chemotype, on male Wistar rats (weighing 250 g at the beginning of the experiments) submitted to the elevated T-maze (ETM). The ETM allows the measurement of two defensive responses: inhibitory avoidance and one-way escape. In terms of psychopathology, these responses have been related to...

The pharmacological effects of 4-phenyl-2-trichloromethyl-3H-1,5-benzodiazepine hydrogen sulfate (PTMB), a novel synthetic benzodiazepine, were examined in mice. In the elevated plus-maze test of anxiety, 0.3-1 mg/kg diazepam ip (F(3,53) = 3.78; P&lt;0.05) and 1-10 mg/kg PTMB ip increased (F(5,98) = 3.26; P&lt;0.01), whereas 2 mg/kg picrotoxin ip decreased (F(3,59) = 8.32; P&lt;0.001) the proportion of time spent in the open arms, consistent with an anxiolytic action of both benzodiazepines, and an anxiogenic role for picrotoxin. In the holeboard, 1.0 mg/kg diazepam ip increased (F(3,54) = 2.78; P&lt;0.05) and 2 mg/kg picrotoxin ip decreased (F(3,59) = 4.69; P&lt;0.01) locomotor activity.

APOA1/C3/A4 gene cluster variability and lipid levels in Brazilian children
Provedor de dados: 56
Autores: França,E. de; Alves,J.G.B.; Hutz,M.H.
Genetic studies have suggested that polymorphisms of genes coding for apolipoproteins are significant determinants of serum lipoprotein and lipid levels in adults. However, only a few studies have investigated the association of these polymorphisms in children. Therefore, in the present investigation we studied the distribution of APOA1 -75 G&gt;A, +83 C&gt;T, APOC3 -482 C&gt;T, -455 T&gt;C and 3238 C&gt;G, and APOA4 Q360H and T347S polymorphisms and their influence on plasma lipoprotein levels in children from a Brazilian northeastern admixed population. The seven polymorphic sites were genotyped in 414 children aged 5 to 15 years (mean 8.9 ± 2.9). The genotypes of the seven polymorphic sites were assessed by PCR-RFLP methods. The frequencies of the less...

Autores: Garda,Horacio Alberto; Toledo,Juan Domingo; González,Marina Cecilia; Prieto,Eduardo Daniel; Cuellar,Luz Ángela; Cabaleiro,Laura Virginia; Chirillano,Lucio Alfonso; Almeyra,Carla Mariel.
La apolipoproteína A-I (apoAI) es el componente proteico mayoritario de las lipoproteínas de alta densidad (HDL), cuyo nivel sérico se correlaciona inversamente con el riesgo aterogénico. Las propiedades antiaterogénicas son atribuidas en gran parte al rol protagónico que tiene en el transporte reverso de colesterol (RCT), proceso que remueve el exceso de colesterol de los tejidos periféricos. La apoAI es una proteína anfitrópica formada casi en exclusividad por a-hélices anfipáticas y presenta una gran flexibilidad conformacional que es crucial para su ciclo funcional, en el que se interconvierte entre diferentes estados: libre, unida a membranas, o a una gran variedad de complejos lipoproteicos de diferente tamaño, morfología y composición.

Apoptosis of sensory neurons and satellite cells after sciatic nerve transection in C57BL/6J mice
Provedor de dados: 56
Autores: Oliveira,A.L.R.
The rate of axonal regeneration, after sciatic nerve lesion in adult C57BL/6J mice, is reduced when compared to other isogenic strains. It was observed that such low regeneration was not due just to a delay, since neuronal death was observed. Two general mechanisms of cell death, apoptosis and necrosis, may be involved. By using the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) technique, we demonstrated that a large number of sensory neurons, as well as satellite cells found in the dorsal root ganglia, were intensely labeled, thus indicating that apoptotic mechanisms were involved in the death process. Although almost no labeled neurons or satellite cells were observed one week after transection, a more than ten-fold increase in...

Application of the comet assay in erythrocytes of Oreochromis niloticus (Pisces): a methodological comparison
Provedor de dados: 74
Autores: Christofoletti,Cintya A.; David,José Augusto O.; Fontanetti,Carmem S.
The present study applied the comet assay to erythrocytes of Oreochromis niloticus with the aim of improving protocols to detect DNA damage in these cells, by using two distinct pHs (pH = 12.1 and pH &gt; 13) and evaluating whether there is a correspondence between silver and ethidium bromide staining. Comets were visually examined and, the frequency of cells with and without damage was obtained, as well as the distribution of classes and scores. By using the Kruskal-Wallis test, our results revealed that pH 12.1 is more effective, although both pHs can be used. Our findings also suggest that silver staining can substitute ethidium bromide, an expensive and highly toxic stain that requires specific equipment for examination.

ABSTRACT The use of traps is extremely important in several types of ecological studies, and may assist in the capture of individuals in areas that are difficult to access. In the present study, we compared the effectiveness of wooden (Schramm) versus "Tomahawk" traps to capture Salvator merianae (Duméril &amp; Bibron, 1839) lizards. The study was conducted in Eldorado do Sul, Rio Grande do Sul, Brazil. Field data were collected from August 2013 to March 2015, during the reproductive period of the species. The study involved two types of baited traps: i) "Tomahawk", made of galvanized steel; and ii) Schramm, a wooden trap. The capture rate of the Schramm wooden traps was 1.63 individuals/day, and of the "Tomahawk" was 0.36 individuals/day. These results...

Provedor de dados: 63
Autores: Soares,Ana Cristina Fermino; Martins,Marco Antônio; Mathias,Lêda; Freitas,Marta Simone Mendonça.
Composition and the role of root flavonoids in the regulation of mycorrhizal symbiosis are still poorly understood. Several flavonoids stimulate spore germination, mycelia growth and root colonization by arbuscular mycorrhizal fungi (AMF), and both root colonization and flavonoid composition are affected by plant nutritional status. Effects of AMF on the occurrence and content of aromatic secondary metabolites in the roots of passion fruit seedlings grown under two levels of phosphorus (P) fertilization (10 and 50 mg kg-1 of phosphorus) was studied. Seedlings were inoculated with Glomus clarum and a population of native fungi from a passion fruit plantation. Methanolic extracts of passion fruit seedlings roots were analyzed by high performance liquid...

Soil information is needed for managing the agricultural environment. The aim of this study was to apply artificial neural networks (ANNs) for the prediction of soil classes using orbital remote sensing products, terrain attributes derived from a digital elevation model and local geology information as data sources. This approach to digital soil mapping was evaluated in an area with a high degree of lithologic diversity in the Serra do Mar. The neural network simulator used in this study was JavaNNS and the backpropagation learning algorithm. For soil class prediction, different combinations of the selected discriminant variables were tested: elevation, declivity, aspect, curvature, curvature plan, curvature profile, topographic index, solar radiation, LS...

A seven month old female goat showed neck swelling, apathy, appetite and weight loss, restlessness, increased salivation, cough, and regurgitation episodes which occurred post feeding. The animal was evaluated through both clinical and radiographic examinations. Plain radiography was performed and contrasted X-ray was done using barium sulfate. For radiological examination, the lateral projection was used for analysis. The results showed a radiopaque content in the esophageal lumen dorsally positioned to heart with density and appearance similar to the rumen. A dilation of the esophagus was reported and a diagnosis of megaesophagus was made. In conclusion, contrast esophagography must be included in the diagnosis of megaesophagus in goats.

Antiretroviral (ARV) therapy has dramatically reduced morbidity and mortality in human immunodeficiency virus 1 (HIV-1) infected children. However, development of ARV resistance in these children is a major public health problem due to lack of availability of and access to new drugs. This study was conducted in order to identify circulating HIV subtypes and recombinant forms and evaluate the drug resistance mutation patterns in 18 HIV-1 infected children failing ARV treatment in Kelantan, Malaysia. Genotyping for codon 1-99 of protease (PR) and 1-250 of reverse transcriptase (RT) were performed by polymerase chain reaction (PCR) amplification and DNA sequencing. Subsequently, these were phylogenetically analyzed to determine the subtypes. CRF33_01B (44.4%)...

Assessment of the degree of contamination of rat germ cell preparations using specific cDNA probes
Provedor de dados: 56
Recent reports showing a decrease in sperm count in men have brought new concerns about male infertility. Animal models have been widely used to provide some relevant information about the human male gamete, and extrapolations are made to men and to the clinical context. The present study assesses one of the methods used for separation of germ cells of the adult rat testis, namely centrifugal elutriation followed by density gradients (Percoll®). This method was chosen since it presents the best results for cell purity in separating germ cells from the rat testis. A comparison between continuous and discontinuous Percoll® gradients was performed in order to identify the best type of gradient to separate the cells. Maximal cell purity was obtained for...

Autores: Somavilla,Alexandre; Fernandes,Itanna Oliveira; Oliveira,Marcio Luiz de; Silveira,Orlando Tobias.
Some neotropical vespids are known for their association with other insects and vertebrate taxa. In the present study about the wasp diversity in the Ducke Reserve, Manaus, Brazil five active colonies and an abandoned one of Polybia rejecta, and one active colony of Synoeca virginea were found associated with ant nests of Azteca aff. chartifex (Formicidae). A single colony of Polybia rejecta was found beside nests of Cacicus cela (Passeriformes: Icteridae). These associations appear to be related both to protection of the wasps nests by the ants and the protection of the ants nests by the wasps, as well as to protection of the bird nests by the wasps. The wasps take advantage of the tolerance of the ants, nesting near their colonies to obtain protection,...

Association between polyclonal B cell activation and the presence of autoantibodies in mice infected with Yersinia enterocolitica O:3
Provedor de dados: 56
Eight-week old conventional female Swiss mice were inoculated intravenously with Yersinia enterocolitica O:3. A second group of normal mice was used as control. Five mice from each group were bled by heart puncture and their spleens were removed for spleen cell collection on the 3rd, 5th, 7th, 10th, 14th and 21st day after infection. Immunoglobulin-secreting spleen cells were detected by the isotype-specific protein A plaque assay. Total immunoglobulin levels were determined in mouse serum by single radial immunodiffusion and the presence of autoantibodies was determined by ELISA. We observed a marked increase in the total number of cells secreting immunoglobulins of all isotypes as early as on the 3rd day post-infection and the peak of secretion occurred...

The genetic basis for dementias is complex. A common polymorphism in the apolipoprotein E (APOE) gene is considered to be the major risk factor in families with sporadic and late-onset Alzheimer's disease as well as in the general population. The distribution of alleles and genotypes of the APOE gene in late-onset Alzheimer's disease (N = 68), other late-life dementias (N = 39), and in cognitively normal controls (N = 58) was determined, as also was the risk for Alzheimer's disease associated with the epsilon4 allele. Peripheral blood samples were obtained from a total of 165 individuals living in Brazil aged 65-82 years. Genomic DNA was amplified by the polymerase chain reaction and the products were digested with HhaI restriction enzyme. APOE epsilon2...

Association of hepatic nuclear factor-4 in the apolipoprotein B promoter: a preliminary report
Provedor de dados: 56
Autores: Nóvak,E.M.; Dantas,K.C.; Charbel,C.E.; Bydlowski,S.P.
Previous studies have examined the arrangement of regulatory elements along the apolipoprotein B (apoB) promoter region (-3067 to +940) and a promoter fragment extending from nucleotides -150 to +124 has been demonstrated to be essential for transcriptional activation of the apoB gene in hepatic and intestinal cells. It has also been shown that transcriptional activation of apoB requires a synergistic interaction between hepatic nuclear factor-4 (HNF-4) and CCAAT/enhancer-binding protein a (C/EBPa) transcription factors. Here, we have examined the hypothesis that HNF-4 factor binding to DNA may induce a DNA helix bend, thus facilitating the communication with a C/EBPa factor located one helix turn from this HNF-4 factor in the apoB promoter. A gel...

Association of leprosy with HLA-DR2 in a Southern Brazilian population
Provedor de dados: 56
The association between HLA specificities and leprosy was investigated in a Southern Brazilian population. One hundred and twenty-one patients and 147 controls were typed for HLA-A, B, Cw, DR and DQ. Patients were subdivided into the following subgroups, according to clinical, histological and immunological criteria: lepromatous (N = 55), tuberculoid (N = 32), dimorphous (N = 20), and indeterminate (N = 14). The frequencies of HLA specificities were compared between the total group of patients and controls, and between the same controls and each subgroup of patients. After correction of the probabilities, deviations were not significant, except for the DR2 specificity, which presented a frequency of 44.2% in the total group of patients and 56.3% in the...

Association of loss of heterozygosity with cytogenetic abnormalities in acute myeloid leukemia and myelodysplastic syndrome
Provedor de dados: 56
Autores: Pinheiro,R.F.; Serio,F.M.; Silva,M.R.R.; Briones,M.R.S.; Chauffaille,M.L.L.F.
Deletions on chromosomes 5 and 7 are frequently seen in myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). It is assumed that these deletions indicate loss of tumor suppressor genes on these chromosomes and until these tumor suppressor genes are identified, the functional consequences of these deletions and the molecular basis of these myeloid disorders cannot be completely understood. We evaluated loss of heterozygosity (LOH) in 44 patients (18 MDS and 26 AML, diagnosed according to WHO classification criteria) at diagnosis, using a four-microsatellite marker panel: an intragenic marker on the 7th intron of gene IRF-1 of the 5q31.1 region and three markers located inside the 7q31.1 region and correlated the LOH with karyotype abnormalities....

RESUMODiversidade genética de Mycoplasma hyopneumoniae tem sido relatada em análise múltipla de repetições em tandem em número variável (MLVA). O objetivo deste estudo foi descrever a distribuição espacial e a heterogeneidade genética de tipos de M. hyopneumoniae no Brasil, bem como investigar a correlação entre regiões de repetição 1 (RR1) e 3 (RR3) de duas adesinas importantes (P97 e P146). Foram identificados 39 tipos de MLVA baseados no número de repetições em tandem em P97 RR1 e RR3 P146. A correlação negativa significativa (Spearman's rho = -0,26; P = 0,022) entre P97 RR1 e RR3 P146 foi observada, o que sugere um possível mecanismo compensatório que permitiria a bactéria manter a sua capacidade de adesão.

Autores: Yeh,E.; Kimura,L.; Errera,F.I.V.; Angeli,C.B.; Mingroni-Netto,R.C.; Silva,M.E.R.; Canani,L.H.S.; Passos-Bueno,M.R.
Association studies between ADIPOR1 genetic variants and predisposition to type 2 diabetes (DM2) have provided contradictory results. We determined if two single nucleotide polymorphisms (SNP c.-8503G&gt;A and SNP c.10225C&gt;G) in regulatory regions of ADIPOR1 in 567 Brazilian individuals of European (EA; N = 443) or African (AfA; N = 124) ancestry from rural (quilombo remnants; N = 439) and urban (N = 567) areas. We detected a significant effect of ethnicity on the distribution of the allelic frequencies of both SNPs in these populations (EA: -8503A = 0.27; AfA: -8503A = 0.16; P = 0.001 and EA: 10225G = 0.35; AfA: 10225G = 0.51; P &lt; 0.001). Neither of the polymorphisms were associated with DM2 in the case-control study in EA (SNP c.-8503G&gt;A: DM2...

This study analyzed associations between the occurrence of mastitis, metritis and retained placenta with the reproductive performance and milk production of four Holstein dairy herds of southern Brazil. Calving-to-conception intervals (CCI) and daily milk production were compared across herds, number of artificial inseminations and clinical occurrences and occurrence of mastitis, metritis and retained placenta. The CCI of cows with three or more clinical occurrences was longer than for those with no occurrences, but shorter for cows with retained placenta than for those without it. Cows with clinical mastitis up to 60 days post-partum had shorter CCI than those with mastitis after 60 days. Cows with retained placenta also had higher frequency of metritis....

Acute promyelocytic leukemia (APL) is characterized by the expansion of blasts that resemble morphologically promyelocytes and harbor a chromosomal translocation involving the retinoic acid receptor a (RARa) and the promyelocytic leukemia (PML) genes on chromosomes 17 and 15, respectively. The expression of the PML/RARa fusion gene is essential for APL genesis. In fact, transgenic mice (TM) expressing PML/RARa develop a form of leukemia that mimics the hematological findings of human APL. Leukemia is diagnosed after a long latency (approximately 12 months) during which no hematological abnormality is detected in peripheral blood (pre-leukemic phase). In humans, immunophenotypic analysis of APL blasts revealed distinct features; however, the precise...

Atrial natriuretic peptide and feeding activity patterns in rats
Provedor de dados: 56
This review presents historical data about atrial natriuretic peptide (ANP) from its discovery as an atrial natriuretic factor (ANF) to its role as an atrial natriuretic hormone (ANH). As a hormone, ANP can interact with the hypothalamic-pituitary-adrenal axis (HPA-A) and is related to feeding activity patterns in the rat. Food restriction proved to be an interesting model to investigate this relationship. The role of ANP must be understood within a context of peripheral and central interactions involving different peptides and pathways

Adult Lymnaea acuminata (average length 20-22 mm) were collected locally from lakes and low-lying submerged fields from Gorakhpur. The chemoattraction studies were made in round glass aquaria measuring 30 cm in diameter and filled to a depth of 10 mm with 500 ml dechlorinated tap water. Each aquarium was divided into four concentric zones. At the starting time of the assay 10 snails were placed on the circumference of outermost zone 0. Snail attractant pellets (SAP) were added simultaneously in the center of central zone 3. SAP of different amino acids were prepared at concentrations of 10, 20, 50, 80 and 100 mM/2% agar solution and, subsequently, spread to a uniform thickness of 5 mm. After cooling, SAP were cut in small pieces of 5 mm in diameter....

Chronic idiopathic urticaria (CIU) is a dermatological syndrome, characterized by raised erythematous skin lesions, that affects 20% of the general population and has been associated with autoimmunity. However, some reports have also suggested a close relationship between CIU and Helicobacter pylori infection, which is endemic in developing countries and associated with chronic gastritis, peptic ulcer disease, and gastric carcinoma. In the present study, we investigated the occurrence of autoantibodies in sera from 23 CIU subjects infected with H. pylori and from 23 CIU subjects without this infection. The presence of anti-thyroid antibodies was determined by indirect hemagglutination assay and the presence of autoantibodies to IgE and C1INH was determined...

Autores: Weirich Neto,Pedro H.; Meer,Roderik W. V. D.; Vink,Peter; Justino,Altair; Garcia,Luiz C.
The use of precision farming tools in pesticide application technology can improve the techniques effectiveness during the spraying. Thus, this study aimed to compare automatic and manual systems to interrupt the syrup flow in the spray bar sections when applied in overlapped areas. The sprayings were carried out in eight places in completely randomized design. It was compared the spray consumption and the sprayed area in relation to the total area. The results indicated that in sprays performed with the automatic system there was an average savings of 17.2% of the sprayed volume. The sprayed area using the bar section's automatic control was an average 6.1% lower than the sprayed area with manual control.

Provedor de dados: 56
Autores: Mazzei de Davila,C.A.; Davila,D.F.; Donis,J.H.; Gonzalo,X.
The medical records of ten pediatric patients with a clinical diagnosis of tetanus were reviewed retrospectively. The heart rate and blood pressure of all tetanus patients were measured noninvasively every hour during the first two weeks of hospitalization. Six of ten tetanus patients presented clinical evidence of sympathetic hyperactivity (group A) and were compared with a control group consisting of four children who required mechanical ventilation for diseases other than tetanus (group B). Heart rate and blood pressure simultaneously and progressively increased to a maximum by day 7. The increase over baseline was 43.70 ± 11.77 bpm (mean ± SD) for heart rate (P&lt;0.01) and 38.60 ± 26.40 mmHg for blood pressure (P&lt;0.01). These values were higher and...

Autonomic processing of the cardiovascular reflexes in the nucleus tractus solitarii
Provedor de dados: 56
The nucleus tractus solitarii (NTS) receives afferent projections from the arterial baroreceptors, carotid chemoreceptors and cardiopulmonary receptors and as a function of this information produces autonomic adjustments in order to maintain arterial blood pressure within a narrow range of variation. The activation of each of these cardiovascular afferents produces a specific autonomic response by the excitation of neuronal projections from the NTS to the ventrolateral areas of the medulla (nucleus ambiguus, caudal and rostral ventrolateral medulla). The neurotransmitters at the NTS level as well as the excitatory amino acid (EAA) receptors involved in the processing of the autonomic responses in the NTS, although extensively studied, remain to be...

ABSTRACT The objective of this paper was to investigate the availability of betaine present in fine wheat bran (FWB) in diets for growing pigs. We used thirty crossbred intact males, housed individually in metabolic cages and distributed in a randomized block design, with five treatments and six replicates. Blocks consisted of two periods of 15 days. Average initial body weights were 32.00±1.30 and 44.90±1.32 kg, in the first and second periods, respectively. Treatments were modified only at the level of methionine plus cysteine (Met+Cys) required and the Met+Cys sources, consisting of a negative control (NC), formulated with 80% of Met+Cys requirements, and four positive controls (PC): PCMet - NC supplemented with 1.2 g kg−1 of DL-methionine; PCBet - NC...

Avaliação da capacidade de rebrotamento pós-distúrbio das plantas lenhosas típicas dos campos rupestres
Provedor de dados: 67
Autores: de Carvalho Barbosa,Bárbara; Siqueira Cappi,Viviane; Pontes Ribeiro,Sérvio; Wilson Fernandes,G.
As plantas possuem eficientes mecanismos a fim de se estabelecerem e permanecerem no ambiente. Um desses mecanismo é capacidade de rebrotamento que algumas espécies apresentam, muitas delas associadas à ambientes propensos à queimadas como é o caso dos ambientes dos campos rupestres. Nesse trabalho foi avaliado a capacidade e morfologia de rebrotamento pós distúrbio em duas populações típicas nos campos rupestres da Serra do Cipó, testando a hipótese de que o fogo (agente do distúrbio) é um agente seletivo dessas espécies e que elas apresentam então esse mecanismo de rebrotamento pós-distúrbio. Para o trabalho foram escolhidas as populações de Dalbergia miscolobium e de Vochysia thyrsoideae que perderam biomassa sobre o solo devido à intensa queimada na...

ABSTRACT Visceral leishmaniasis is a zoonosis in which the dog appears as the main source of infection in urban areas. Its diagnosis is complex and the cytopathological exam is a fast and cheap alternative to parasite direct visualization and its sensitivity can be increased by immunocytochemistry, though with a higher cost. The accuracy of such methods is dependent on the microscopist's experience and therefore, this study evaluated the reliability of such techniques between two observers, from bone marrow aspirates of 50 dogs from an endemic area for the disease. The parasitological culture in Novy-MacNeal-Nicolle medium was used as the reference standard. Among the main findings, the sensitivities obtained by observers I and II were respectively 62.5%...

ABSTRACT Tonic immobility (TI) is a way to measure fear, as characterized by the reduced capacity to respond to external stimuli. The time spent in TI indicates the level of fear. Since TI is measured as the time until event occurrence, survival analysis stands out as a suitable statistical method to treat these data. We aimed to investigate the influence of possible factors (lines, sex and age) on fear behavior in meat quail (Coturnix coturnix) measured through TI by using survival analysis (non parametric Kaplan-Meyer method via logrank test). The dataset was composed by TI information provided by 50 animals from each line (UFV1 and UFV2) in each age (14 and 28 days of age), totalizing 200 records. Despite the slight difference between the two evaluated...

Nineteen sera and blood samples from wild feline kept in captivity were tested for Toxoplasma gondii antibody and presence of feline immunodeficiency virus (FIV) DNA, respectively. Eighteen (94.7%) of the them were seropositive for toxoplasma. However, the only negative animal, a Leopardus pardalis, was the only FIV positve. These results suggest that the infection by FIV may have compromised its immune system and interfered with antibody production for toxoplasma.

Bait traps remain attractive to euglossine bees even after two weeks: a report from Brazilian Atlantic forest
Provedor de dados: 92
Autores: Coswosk,Judson Albino; Soares,Elaine Della Giustina; Faria,Luiz R.R.
ABSTRACT Bait traps are effective and commonly used method in the studies of orchid bees. Important questions in the context of this method, including those related to bait dispersion, how long baits remain attractive, the distance from which males are supposed to be attracted to lures and so on, are still open subjects. Data on the attractiveness of bait traps that have remained in the field during two weeks in a large Atlantic forest preserve are presented. Four main results emerge from the data: (i) the abundance of specimens collected per day decreased in all the attractants as the traps were left on the field; (ii) despite this decrease, the absolute number of individuals collected after eight and fifteen days is remarkably, mostly in eugenol and...

We analyzed the trends of scientific output of the University Hospital, Federal University of Rio de Janeiro. A total of 1420 publications were classified according to pattern and visibility. Most were non-research publications with domestic visibility. With time, there was a tendency to shift from non-research (or education-oriented) publications with domestic visibility to research publications with international visibility. This change may reflect new academic attitudes within the institution concerning the objectives of the hospital and the establishment of scientific research activities. The emphasis of this University Hospital had been on the training of new physicians. However, more recently, the production of new knowledge has been incorporated as...

Brazil has a unique position in the world. It is one of the few countries that can be one of the most important producers of food, fiber and biofuel and at the same time maintain its mega biodiversity endowment and vital ecosystems services properly running. This is a challenge that only can be achieved by recognizing the importance of agribusiness sector to the Brazilian economy, but also that ecosystems have limits and we should not endless expand agriculture in the name of "development". Ecosystem services have to be recognized also as a "development" to be kept for the next generations. Agriculture only exists where ecosystems are able to maintain its basic functioning. Therefore, a well preserved nature it is the most precious asset of agriculture.

Ballast water: a review of the impact on the world public health
Provedor de dados: 80
Autores: Takahashi,CK; Lourenço,NGGS; Lopes,TF; Rall,VLM; Lopes,CAM.
Since the nineteenth century ships have been using ballast water (BW) for safety, stability, propulsion and maneuverability, as well as to redress loss of fuel weight and water consumption, and to maintain structural stress at acceptable levels. Ballast water has been spreading many non-native species around the globe, but little is known about the extent and potential significance of ship-mediated transfer of microorganisms. The global movements of ballast water by ships create a long-distance dispersal mechanism for human pathogens that may be important in the worldwide distribution of microorganisms, as well as for the epidemiology of waterborne diseases. Only a few studies have been carried out on this subject, most of them involving ballast water...

Autores: Almeida,Wellington Romualdo de; Guimarães,Silvia Maria Pita de Beauclair; Moura,Carlos Wallace do Nascimento.
We report here the first occurrence of Bangiopsis subsimplex (Mont.) F.Schmitz (Rhodophyta) for the northeastern coast of Brazil. The specimen was isolated from a laboratory sample of mollusk shells collected in Baía de Todos os Santos (Bimbarras Island, Brazil) and was held in sterilized seawater (33 UPS) enriched with 25% Provasoli solution. In the American Atlantic region, B. subsimplex presents a northern distribution limit at French Guiana and a southern limit at São Paulo. We conclude that the distribution of B. subsimplex has expanded, since the species was once known only to the southeastern Brazil, specifically to São Paulo.

Batch ethanol fermentation: the correlation between the fermentation efficiency and the biomass initial concentration depends on what is considered as produced ethanol
Provedor de dados: 58
Autores: Borzani,Walter.
Although numerous studies have examined many of the factors that affect the efficiency of batch ethanol fermentation, little attention has been paid to the influence of the biomass concentration on this efficiency. This paper shows that the influence of the biomass initial concentration on the fermentation efficiency depends on what is considered "produced ethanol". If only the ethanol present in the medium aqueous phase at fermentation completion is considered, the fermentation efficiency linearly decreases when the biomass initial concentration increases. If, however, the intracellular ethanol is also considered as produced ethanol, the fermentation efficiency is not affected by the biomass concentration.

Bats used as hosts by Amblyomma sculptum (Acari: Ixodidae) in Northeastern Brazil and its implications on tick-borne diseases
Provedor de dados: 103
Autores: Novaes,Roberto Leonan M.; Alves,Fernanda M.; Souza,Renan F.; Laurindo,Rafael S.; Moratelli,Ricardo.
ABSTRACT Amblyomma Koch, 1844 is distributed worldwide, with ca. 130 species currently recognized. These ticks are vectors of pathogens to animals and humans, including the causative agent of the New World Rocky Mountain spotted fever. Species of the Amblyomma parasitize a wide range of organisms, especially medium and large terrestrial mammals. Here we report for the first time the association of Myotis lavali Moratelli, Peracchi, Dias &amp; Oliveira, 2011, Noctilio albiventris Desmarest, 1818 and Noctilio leporinus (Linnaeus, 1758) as hosts for Amblyomma sculptum Berlese, 1888. The ticks were originally identified as Amblyomma cajennense (Fabricius, 1787), in 2011. However, a later taxonomic review indicated that the species of the A. cajennense complex...

BCG lymphadenopathy detected in a BCG-vaccinated infant
Provedor de dados: 56
Autores: Barouni,A.S.; Augusto,C.; Queiroz,M.V.N.P.; Lopes,M.T.P.; Zanini,M.S.; Salas,C.E.
Large-scale vaccination with BCG, the live attenuated strain of Mycobacterium bovis, is being adopted around the world, although sporadic complications have occurred after the procedure. Lymphadenopathy is not uncommon especially in babies under one year (0.73% of vaccinated infants), but the swelling subsides within 2 months in most cases, with no medical or surgical treatment. Brazil adopted BCG vaccination program earlier in the seventies and by 1995 more than 96% of the infant population received this immunization. We report here the occurrence of lymphadenopathy in a two-year-old child vaccinated with the Brazilian BCG strain. The diagnosis was made using a lymph node biopsy and intestinal aspirates that yielded a positive mycobacterial culture. The...

Autores: Ferraz,Patricia F. P.; Yanagi Junior,Tadayuki; Alvarenga,Talita A. C.; Reis,Gregory M.; Campos,Alessandro T.
In the first week of a chick life, broilers are very sensitive to different conditions outside their thermoneutral zone. Thus, the goal of this study was to evaluate the behaviors and productive responses of broilers subjected to conditions of thermal comfort or challenge at different intensities (27, 30, 33 and 36ºC) and durations (1, 2, 3 and 4 days starting on the second day of life). In the experiment, ten minutes of images from each hour of each treatment were analyzed to evaluate the key behaviors of the birds. Similar behavior at different dry-bulb air temperatures were identified by using Ward's method of cluster analysis. These behaviors were grouped by dendograms in which the similarity of these data was qualified. Feed intake, water intake and...

Autores: Santana,A.N.C.; Trindade-Filho,E.M.; Cunha,R.B.; Sousa,M.V.; Cavalheiro,E.A.; Carvalho,K.M.
In this study, the behavioral and electroencephalographic (EEG) analysis of seizures induced by the intrahippocampal injection in rats of granulitoxin, a neurotoxic peptide from the sea anemone Bunodosoma granulifera, was determined. The first alterations occurred during microinjection of granulitoxin (8 µg) into the dorsal hippocampus and consisted of seizure activity that began in the hippocampus and spread rapidly to the occipital cortex. This activity lasted 20-30 s, and during this period the rats presented immobility. During the first 40-50 min after its administration, three to four other similar short EEG seizure periods occurred and the rats presented the following behavioral alterations: akinesia, facial automatisms, head tremor, salivation,...

Besleria longimucronata (Gesneriaceae) y sus ladrones de néctar: ¿cuáles son las consecuencias sobre el éxito reproductivo en esta supuesta interacción negativa?
Provedor de dados: 67
Autores: de Avila Jr,Rubém Samuel.
Las interacciones antagonistas suelen ser clasificadas como negativas para el éxito reproductivo de los individuos. Entre estas interacciones, el comportamiento de pillaje de néctar floral por distintos grupos animales es una de las más frecuentes en las angiospermas. Los antagonismos constituyen importantes fuerzas selectivas de las características florales, del tipo y cantidad de recurso ofrecido, y del período de floración. Por esta razón es necesario analizar las distintas etapas reproductivas de las plantas considerando el posible efecto negativo de los pilladores de néctar, y así comprender mejor su impacto sobre el éxito reproductivo. Las flores de Besleria longimucronata presentaron una gran tasa de pillaje en observaciones efectuadas en 2005. El...

Bicarpellate gynoecium in two species of Senna (Fabaceae, Caesalpinioidae, Cassiinae)
Provedor de dados: 39
Autores: Almeida,Natan Messias; Siqueira Filho,José Alves; Oliveira,Paulo Eugênio; Novo,Reinaldo Rodrigo; Castro,Cibele Cardoso.
ABSTRACT Flowers of species of Senna are very morphologically diverse, however, nothing has been reported regarding variation in the presence of a unicarpellate gynoecium, which is characteristic of the group. This study reports the occurrence of a bicarpellate gynoecium in two enantiostylous species of Senna in an area of dry forest (Caatinga) in NE Brazil. Observations of floral morphology and estimates of the proportions of floral morphs in the populations were performed. The species produce three floral types: left (L), right (R) and bicarpellate (B). The proportion of these floral morphs were similar in the populations of Senna macranthera var. micans, but the number of B flowers in populations of S. trachypus was lower than that recorded for L and R...

Biflavonoids inhibit the production of aflatoxin by Aspergillus flavus
Provedor de dados: 56
Autores: Gonçalez,E.; Felicio,J.D.; Pinto,M.M.
The biflavonoids 6,6"-bigenkwanin, amenthoflavone, 7,7"-dimethoxyagastisflavone and tetradimethoxybigenkwanin isolated from Ouratea species were tested for inhibitory activity on Aspergillus flavus cultures. Suspensions of Aspergillus flavus spores were inoculated into 50 ml of YES medium at different biflavonoid concentrations: 5 and 10 µg/ml for 6,6"-bigenkwanin, amenthoflavone and 7,7"-dimethoxyagastisflavone, and 5, 10, 15 and 20 µg/ml for tetradimethoxybigenkwanin. The four biflavonoids showed inhibitory activity on aflatoxin B1 and B2 production (P&lt;0.001), but did not inhibit fungal growth at the concentration tested (P&gt;0.05). These results show that biflavonoids can be used for the development of agents to control aflatoxin production.

Binding sites and actions of Tx1, a neurotoxin from the venom of the spider Phoneutria nigriventer, in guinea pig ileum
Provedor de dados: 56
Autores: Santos,R.G.; Diniz,C.R.; Cordeiro,M.N.; De Lima,M.E.
Tx1, a neurotoxin isolated from the venom of the South American spider Phoneutria nigriventer, produces tail elevation, behavioral excitation and spastic paralysis of the hind limbs after intracerebroventricular injection in mice. Since Tx1 contracts isolated guinea pig ileum, we have investigated the effect of this toxin on acetylcholine release, as well as its binding to myenteric plexus-longitudinal muscle membranes from the guinea pig ileum. [125I]-Tx1 binds specifically and with high affinity (Kd = 0.36 ± 0.02 nM) to a single, non-interacting (nH = 1.1), low capacity (Bmax 1.1 pmol/mg protein) binding site. In competition experiments using several compounds (including ion channel ligands), only PhTx2 and PhTx3 competed with [125I]-Tx1 for specific...

Autores: Amini,Marzyeh; Nahrevanian,Hossein; Khatami,Shohreh; Farahmand,Mahin; Mirkhani,Fatemeh; Javadian,Seifoddin.
Several enzymes that contribute to immune system responses require zinc and copper as trace elements for their activity. We examined zinc and copper levels in two susceptible Balb/c mouse lines and resistant C57bl/6 mice infected with Leishmania major MRHO/IR/75/ER, a prevalent strain that causes cutaneous leishmaniasis in Iran. Serum Zn and Cu were determined by flame atomic absorption spectrophotometry. Higher Cu levels were found in infected C57bl/6 mice and higher Zn levels were found in infected Balb/c mice. Also, Cu/Zn ratios were increased in both the Balb/c and the C57bl/6 mice. We conclude that concentrations of essential trace elements vary during cutaneous leishmaniasis infection and that this variation is associated with...

Autores: Yilmaz,O.; Yurt Lambrecht,F.; Soylu,A.; Durkan,K.; Kavukcu,S.
The distribution of creatinine, one of the toxic guanidine compounds, in various tissues has not been studied in detail by using radiolabeled creatinine. Our objective was to investigate the biodistribution of creatinine labeled with 99m technetium (99mTc) by the stannous (II) chloride method in healthy male Wistar rats. Quality controls were carried out by radio thin layer chromatography, high-performance liquid chromatography, and paper electrophoresis. The labeling yield was 85 ± 2% under optimum conditions (pH 7 and 100 µg stannous chloride). Rats (N = 12) were injected intravenously with 99mTc-creatinine and their blood and visceral organs were evaluated for 99mTc-creatinine uptake as percent of the injected dose per gram wet weight of each tissue...

Patients expressing estradiol receptors in melanoma cells have been reported to have a better prognosis. We therefore decided to investigate the in vitro effects of ß-estradiol and tamoxifen on the growth and tyrosinase activity of SK-Mel 23 human melanoma cells. Twenty-four-hour treatment with 0.4 nM ß-estradiol inhibited cell proliferation in 30% (0.70 ± 0.03 x 10(5) cells) and increased tyrosinase activity in 50% (7130.5 ± 376.5 cpm/10(5) cells), as compared to untreated cells (1.0 ± 0.05 x 10(5) cells and 4769 ± 25.5 cpm/10(5) cells, respectively). Both responses were completely (100%) blocked by 1 µM tamoxifen. Higher concentrations (up to 1.6 nM) or longer treatments (up to 72 h) did not result in a larger effect of the hormone on proliferation or...

Diatraea flavipennella (Box) (Lepidoptera, Crambidae) is one of the most destructive pests in sugarcane plantations in the Northeast Region of Brazil. Developmental characteristics and parasitism potential of the egg parasitoids Telenomus alecto Crawford (Hymenoptera, Scelionidae) and Trichogramma galloi Zucchi (Hymenoptera, Trichogrammatidae) were compared with the aim of selecting a suitable species for biological control of D. flavipennella. Both T. alecto and T. galloi developed well and were readily adapted to D. flavipennella eggs as host. Although, T. galloi presented higher viability, with more adults emerging per host egg and higher sex ratio, the developmental period (egg-adult) was shorter in T. alecto and female longevity was extended. In...

Provedor de dados: 103
Autores: Rondineli,Giulianna; Carmassi,Alberto Luciano; Braga,Francisco Manoel de Souza.
Taunayia bifasciata (Eigenmann &amp;amp; Norris, 1900) is a small catfish that inhabits headwater streams of the Tietê and Paraíba do Sul river basins, southeastern Brazil, being restricted to the Atlantic rain forest. The species is found on lists of threatened species of Brazil and the state of São Paulo. Despite that, there is no literature information about the biology of the species. In the present study we endeavored to collect data on the biology of T. bifasciata. A total of 37 specimens were captured in two streams, Piracuama and Oliveiras. Of those, 22 were females, 14 were males and 1 specimen was immature. Adults with mature gonads were captured in all samples excepting the last, suggesting that T. bifasciata has a long reproductive season. The...

BIOTA/FAPESP, Brazil's model program for assessing global biodiversity
Provedor de dados: 49
Autores: Staley,James T.
Brazils state of São Paulo ranks among the few governments that has recognized the importance of biodiversity. It has successfully launched Biota as part of its FAPESP program in biology. The Biota program has been in operation for three years now, long enough to pose questions about its promise. The questions I will try to address here are: What attributes of the Biota progam have allowed it to succeed where others have failed? Can the Biota program serve as a global model for biodiversity efforts?

Autores: De Angelis,K.; Gama,V.M.; Farah,V.A.M.; Irigoyen,M.C.
The use of colored microspheres to adequately evaluate blood flow changes under different circumstances in the same rat has been validated with a maximum of three different colors due to methodological limitations. The aim of the present study was to validate the use of four different colors measuring four repeated blood flow changes in the same rat to assess the role of vasopressor systems in controlling arterial pressure (AP). Red (150,000), white (200,000), yellow (150,000), and blue (200,000) colored microspheres were infused into the left ventricle of 6 male Wistar rats 1) at rest and 2) after vasopressin (aAVP, 10 µg/kg, iv), 3) renin-angiotensin (losartan, 10 mg/kg, iv), and 4) sympathetic system blockade (hexamethonium, 20 mg/kg, iv) to determine...

Body orientation for thermoregulation and daily activity cycle of Mabuya macrorhyncha (Squamata: Scincidae)
Provedor de dados: 103
Autores: Maia-Carneiro,Thiago; Winck,Gisele R.; Pereira,Mariana Rodrigues; Rocha,Carlos Frederico Duarte.
ABSTRACT We investigated the daily activity and thermoregulatory body orientation of Mabuya macrorhyncha (Hoge, 1947), a lizard species that occurs in the Brazilian Atlantic Forest. We conducted this investigation in a sandy coastal dune remnant (“restinga” ecosystem) in Grussaí, state of Rio de Janeiro, Brazil, during the summer. The daily activity cycle of the lizards started around 6:00 am and ended before 7:00 pm. This is longer than observed in other populations of M. macrorhyncha (approximately 7:00 am to 5:00 pm). The activity cycle of the lizards was bimodal, with the first peak between 6:00 and 11:00 am and the second from 2:00 to 7:00 pm. This contrasts with observations on other populations of this species, which revealed an unimodal pattern....

Bombus brasiliensis Lepeletier (Hymenoptera, Apidae) infected with Nosema ceranae (Microsporidia)
Provedor de dados: 92
Autores: Plischuk,Santiago; Lange,Carlos E.
ABSTRACT Heavy infections caused by a microsporidium were detected in midgut epithelium cells of two adult workers of the bumble bee Bombus brasiliensis Lepeletier collected near Puerto Iguazú, Misiones province, Argentina. Microsporidium rRNA (16S small subunit) was amplified by 218MITOC primers and produced amplicons indicating presence of Nosema ceranae Fries et al., a virulent pathogen of more than 20 bee species, possibly involved in Apis mellifera L. Colony Collapse Disorder. Campaigns in search of B. brasiliensis between 2008 and 2015 have revealed a possible narrower range in the southeastern area of its known distribution. Effects of N. ceranae infections could be modulating their populations and should not be overlooked. In addition, the wide...

Autores: Roodt,Adolfo R.
Se presentan imágenes de Bothrops ammodytoides ("yarará ñata"), mostrando su patrón de coloración característica y los rasgos que permiten diferenciarla de otras especies de Bothrops que se encuentran en la Argentina. Esta serpiente venenosa es la más austral del mundo y la única serpiente venenosa autóctona de Argentina. Son serpientes pequeñas, sin embargo su mordedura puede producir envenenamientos en seres humanos con riesgo de muerte. Si bien es conocida por su nariz respingada, algunos ejemplares no manifiestan en demasía esa característica, situación que no impide que se la pueda diferenciar de otras especies de Bothrops presentes en el territorio argentino. Aunque los antivenenos de uso corriente para tratar envenenamientos botrópicos en la...

Bradykinin enhances membrane electrical activity of pancreatic beta cells in the presence of low glucose concentrations
Provedor de dados: 56
Autores: Moura,A.S.
In most of cells bradykinin (BK) induces intracellular calcium mobilization. In pancreatic beta cells intracellular calcium is a major signal for insulin secretion. In these cells, glucose metabolism yields intracellular ATP which blocks membrane potassium channels. The membrane depolarizes, voltage-dependent Ca2+ channels are activated and the intracellular calcium load allows insulin secretion. Repolarization occurs due to activation of the Ca2+-dependent K+ channel. The insulin secretion depends on the integrity of this oscillatory process (bursts). Therefore, we decided to determine whether BK (100 nM) induces bursts in the presence of a non-stimulatory glucose concentration (5.6 mM). During continuous membrane voltage recording, our results showed...

Brazilian cleaner birds: update and brief reappraisal
Provedor de dados: 49
Autores: Sazima,Ivan; Sazima,Cristina.
Some bird species feed on external parasites, such as ticks and flies, on the body of mammals (hosts or clients). So called cleaner birds that occur in Brazil were reviewed recently, but gathering of significant new data indicates the need for an update and a brief reappraisal of such association. New records raise the number of known clients for some cleaning birds. The Southern Caracara (Caracara plancus) picks ticks on cattle, and the Black Caracara (Daptrius ater) picks ticks on capybaras. The Wattled Jacana (Jacana jacana) picks ticks, horseflies, arthropods and organic debris on capybaras, and tick-picking on capybaras by the Shiny Cowbird (Molothrus bonariensis) is substantiated by photographs. The Cattle Tyrant (Machetornis rixosa) deftly catches...

Brazilian medical publications: citation patterns for Brazilian-edited and non-Brazilian literature
Provedor de dados: 56
Autores: Cunha-Melo,J.R.; Santos,G.C.; Andrade,M.V.
Today, the quality of a scientific article depends on the periodical in which it is published and on the number of times the article is cited in the literature. In Brazil, the criteria for the evaluation of this scientific production are improving. However, there is still some resistance, with authors arguing that Brazilian publications must be preferentially addressed to the national readers and, therefore, they should ideally be written in Portuguese. In order to determine the kind of scientific journals cited in the reference lists of articles published in medical periodicals edited in Brazil, in the present study we determine the rate of Portuguese/English citations. Three issues of 43 periodicals (19 indexed in SciELO, 10 in PubMed, 10 in LILACS, and...

Bringing to light the molecular evolution of GUX genes in plants
Provedor de dados: 74
Autores: Gallinari,Rafael Henrique; Coletta,Rafael Della; Araújo,Pedro; Menossi,Marcelo; Nery,Mariana Freitas.
Abstract Hemicellulose and cellulose are essential polysaccharides for plant development and major components of cell wall. They are also an important energy source for the production of ethanol from plant biomass, but their conversion to fermentable sugars is hindered by the complex structure of cell walls. The glucuronic acid substitution of xylan (GUX) enzymes attach glucuronic acid to xylan, a major component of hemicellulose, decreasing the efficiency of enzymes used for ethanol production. Since loss-of-function gux mutants of Arabidopsis thaliana enhance enzyme accessibility and cell wall digestion without adverse phenotypes, GUX genes are potential targets for genetically improving energy crops. However, comprehensive identification of GUX in...

Autores: Bueno,Carlos Roberto; Weigel,Peter.
Summary Rhizomes of aria (Calathea allouia) normally have low viability or slow shoot Iniciation. Various treatments were used to accelerate water penetration in order to stimulate iniciation. The rhizomes were immersed in a hot water (48°C) for 10. 20 or 30 minutes or cold water (ambient temperature) for 24. 48, 96 or 168 hours and compared with a control. The results show a significant increase in percentage of shoot iniciation when the rhizomes were immersed in hot water foi 10 minutes. Orther treatments did not stimulate iniciation and in some cases negative effects were observed. However, leaf number, 90 days after planting, did not vary significatly between treatments.

ABSTRACT  In recent years, platycarpa peaches have reached high prices due to their good acceptance in the international market. However, the great majority of the released varieties are high chill and do not adapt to Brazilian conditions except on a few microclimes of high altitudes. The cultivar BRS Mandinho is the first peach cultivar of the botanical variety platicarpa, released in Brazil and adapted to subtropical conditions. The plants are vigorous and, in the state of Rio Grande do Sul, the blooming occurs on the second half of July. The fruits are sweet and ripe in November with an average weight of 55.3 g.

Abstract  Even though the peach tree was introduced in Brazil during the XVI century, it was only on the 1940’s that the first peach breeding program started in the country. Later on, other programs started being, until now, the largest ones, and the programs that gave more significant contributions to the peach crop development those from the Instituto Agronômico de Campinas and from Embrapa Temperate Agriculture. Presently, peach is cultivated not only in the colder areas of the South but also in the subtropics and high altitude areas of the tropics, due to dozens of cultivars released by these breeding programs. Peaches are sold entirely in the domestic market and in the largest consumers market, State of São Paulo, the preference is for white sweet...

Ca2+ dependence of gluconeogenesis stimulation by glucagon at different cytosolic NAD+-NADH redox potentials
Provedor de dados: 56
The influence of Ca2+ on hepatic gluconeogenesis was measured in the isolated perfused rat liver at different cytosolic NAD+-NADH potentials. Lactate and pyruvate were the gluconeogenic substrates and the cytosolic NAD+-NADH potentials were changed by varying the lactate to pyruvate ratios from 0.01 to 100. The following results were obtained: a) gluconeogenesis from lactate plus pyruvate was not affected by Ca2+-free perfusion (no Ca2+ in the perfusion fluid combined with previous depletion of the intracellular pools); gluconeogenesis was also poorly dependent on the lactate to pyruvate ratios in the range of 0.1 to 100; only for a ratio equal to 0.01 was a significantly smaller gluconeogenic activity observed in comparison to the other ratios. b) In the...

Autores: Silvarolla,Maria Bernadete; Mazzafera,Paulo; Lima,Marinez Muraro Alves de.
The coffee germplasm bank of the Instituto Agronômico de Campinas has many Coffea arabica accessions from Ethiopia, which is considered the primary center of genetic diversity in coffee plants. An evaluation of the caffeine content of beans from 99 progenies revealed intra- and inter-progeny variability. In 68 progenies from the Kaffa region we found caffeine values in the range 0.46-2.82% (mean 1.18%), and in 22 progenies from Illubabor region these values ranged from 0.42 to 2.90% (mean 1.10%). This variability could be exploited in a breeding program aimed at producing beans with low-caffeine content.

Calcium handling by vascular myocytes in hypertension
Provedor de dados: 56
Calcium ions (Ca2+) trigger the contraction of vascular myocytes and the level of free intracellular Ca2+ within the myocyte is precisely regulated by sequestration and extrusion mechanisms. Extensive evidence indicates that a defect in the regulation of intracellular Ca2+ plays a role in the augmented vascular reactivity characteristic of clinical and experimental hypertension. For example, arteries from spontaneously hypertensive rats (SHR) have an increased contractile sensitivity to extracellular Ca2+ and intracellular Ca2+ levels are elevated in aortic smooth muscle cells of SHR. We hypothesize that these changes are due to an increase in membrane Ca2+ channel density and possibly function in vascular myocytes from hypertensive animals. Several...

Can calories from ethanol contribute to body weight preservation by malnourished rats?
Provedor de dados: 56
Autores: Aguiar,A.S.; Da-Silva,V.A.; Boaventura,G.T.
Our objective was to compare the use of calories from ethanol by well-nourished and malnourished rats in terms of body weight. Female Wistar rats weighing 170-180 g at the beginning of the study were used. The animals were divided into two groups (N = 12 each): group W received water ad libitum and group E an ethanol solution ad libitum as the only source of liquid throughout the experiment. The concentration of ethanol was increased weekly from 0 to 5, 10, 20 and 40% (v/v). In the well-nourished phase (A), all rats received food ad libitum (AW and AE). Ethanol treatment (AE) was then interrupted and water was offered to both groups. After 2 weeks both AW and AE rats were submitted to food restriction (50% of group AW food consumption), thus initiating the...

Provedor de dados: 56
Autores: Soares,L.L.; Lucas,A.M.M.; Boaventura,G.T.
We evaluated the protein quality of organic and transgenic soy fed to rats throughout life. Thirty female Wistar rats were divided into three groups (N = 10): organic soy group (OSG) receiving organic soy-based diet, genetically modified soy group (GMSG) receiving transgenic soy-based diet, and a control group (CG) receiving casein-based diet. All animals received water and isocaloric diet (10% protein), ad libitum for 291 days. After this, the weight of GMSG animals (290.9 ± 9.1 g) was significantly lower (P &lt;= 0.04) than CG (323.2 ± 7.9 g). The weight of OSG (302.2 ± 8.7 g) was between that of the GMSG and the CG. Protein intake was similar for OSG (308.4 ± 6.8 g) and GMSG (301.5 ± 2.5 g), and significantly lower (P &lt;= 0.0005) than the CG (358.4 ±...

Can Sarcophagidae (Diptera) be the most important entomological evidence at a death scene? Microcerella halli as a forensic indicator
Provedor de dados: 92
Autores: Vairo,Karine Pinto; Caneparo,Maria Fernanda da Cruz; Corrêa,Rodrigo César; Preti,Daniel; Moura,Mauricio Osvaldo.
Abstract Although a corpse can harbor several species of flies, only a few have been sufficiently studied to be used as forensic indicators. Sarcophagidae are an example of how the forensic use of insects can be impaired by taxonomic and biological data limitation. This manuscript provides the first record of the Neotropical flesh fly Microcerella halli (Engel, 1931) on a human body and its use in forensics. M. halli and Sarconesia chlorogaster (Widemann, 1830) were sampled from a body located indoors at 20 °C. Only M. halli was used to estimate the mPMI (minimum post mortem interval) because it was the oldest larval stage on the corpse. Based on the development time of M. halli we estimate an mPMI of at least 10 days. In addition, we provide for the first...

Autores: Palmero,Edenir Inêz; Campacci,Natalia; Schüler-Faccini,Lavinia; Giugliani,Roberto; Rocha,José Claudio Casali da; Vargas,Fernando Regla; Ashton-Prolla,Patricia.
Abstract In Brazil, the population in general has little knowledge about genetic risks, as well as regarding the role and importance of the Cancer Genetic Counseling (CGC). The goal of this study was to evaluate cancer-related worry and cancer risk perception during CGC sessions in Brazilian women at-risk for hereditary breast cancer. This study was performed in 264 individuals seeking CGC for hereditary breast cancer. Both cancer-affected and unaffected individuals were included. As results, individuals with and without cancer reported different motivations for seeking CGC and undergoing genetic testing. A correlation was observed between age at the first CGC session and age at which the closest relative was diagnosed with cancer. Multivariate analysis...

Yeasts are becoming a common cause of nosocomial fungal infections that affect immunocompromised patients. Such infections can evolve into sepsis, whose mortality rate is high. This study aimed to evaluate the viability of Candida species identification by the automated system Vitek-Biomerieux (Durham, USA). Ninety-eight medical charts referencing the Candida spp. samples available for the study were retrospectively analyzed. The system Vitek-Biomerieux with Candida identification card is recommended for laboratory routine use and presents 80.6% agreement with the reference method. By separate analysis of species, 13.5% of C. parapsilosis samples differed from the reference method, while the Vitek system wrongly identified them as C. tropicalis, C....

Capacidade máxima de adsorção de fósforo e constante de energia em Latossolo Bruno em razão de diferentes ajustes do modelo Langmuir
Provedor de dados: 90
Autores: Oliveira,Clovisson Menotti Boeira de; Gatiboni,Luciano Colpo; Miquelluti,David José; Smyth,Thomas Jot; Almeida,Jaime Antonio.
A capacidade máxima de adsorção de fósforo (CMAP) é um parâmetro bastante útil para caracterizar a capacidade de adsorção de fósforo (P) do solo e, por isso, o modelo de Langmuir, que possibilita essa estimativa, é bastante difundido. Porém, se o ajuste da equação for realizado por modelos não lineares ou linearizados, ou se forem escolhidos modelos de região única ou múltiplas, nem sempre os valores estimados da CMAP e da constante de energia de ligação (k) são semelhantes. O objetivo deste trabalho foi avaliar o efeito do uso de diferentes métodos de ajuste do modelo de Langmuir sobre os valores estimados de CMAP e k. Para isso, utilizouse um único solo de alta capacidade de adsorção de P, o qual foi misturado a quantidades crescentes de areia lavada,...

ABSTRACT Pregnancy can cause several physiologic changes in mares, including modifications in cardiac output and heart positioning. Therefore, these changes could influence electrocardiographic parameters in various stages of pregnancy. This study aimed to evaluate the electrocardiogram of Crioulo mares in different pregnancy stages. Nine non pregnant mares (G0), 11 mares at three months (G3), 11 mares at six months (G6) and 11 mares at 10 months of pregnancy (G10) were submitted to electrocardiographic evaluation. There was higher (P= 0,002) heart rate of G10 (60.45±12.16bpm) when compared to other groups (G0=45.67±10.75bpm; G3=44.91±7.91bpm; G6=46.91±9.12bpm), probably because of an increase in cardiac output to uterine perfusion at the end of pregnancy....

This study evaluated the clonal spread of carbapenem-resistant P. aeruginosa producing SPM-1 type metallo-Î²-lactamase (MBL), at the university hospital of Florianópolis, Santa Catarina, Brazil, compared to an epidemic clone previously reported, as well as strains collected in other three Brazilian states. Among the isolates, 17 (62%) were clonal and highly related to strains from other regions of Brazil. Six clonal strains harbored the blaSPM-1 gene. The finding of a unique SPM-1 producer clone suggests that its dissemination has contributed to the high resistance to carbapenems in Brazilian hospitals

Autores: VECCELLI,JULIANA CRISTINA; SIQUEIRA,DALMO LOPES DE.
ABSTRACT  The aim of this study was to evaluate the response of mango plants ( L) ‘Mangifera indicaTommy Atkins’ cultivar to different NaCl concentrations. In this experiment, plants were grown in pots with washed sand and nutrient solution with 0, 10, 20 and 30 mM NaCl for 120 days. After this period, young leaves from the last growth spurt were harvested in a randomized block design, dried at 65 °C for 72 h and ground in a ball mill. Samples were dried again in an oven at 60 °C for 24 h and then the relative abundance of 13C and 12C isotopes was determined using mass spectrometer Sercon 20-20 isotope ratio model. Data were used to determine the carbon isotopic discrimination (?). It was concluded that ‘Tommy Atkins’ mango trees submitted to 30 mmol L-1...

Carbon sequestration in the rain forest: alternatives using environmentally friendly biotechnology
Provedor de dados: 49
Autores: Buckeridge,Marcos S.; Aidar,Marcos P.M.
As carbon dioxide increases on Earth atmosphere, the rise in average temperatures may provoke changes in the environment that could damage civilisation as we know it. As a result, the need to sequester carbon becomes urgent, and one of the options we have is to use the potential of the forests to do it by enhancing assimilation of CO2 through photosynthesis. However, if we consider the use of plants to increase carbon sequestration, a problem that looms is that species often acclimate and actually reduce CO2 assimilation through feedback mechanisms of the sugars that are the product. In the present article, we propose that some biochemical pathways, such as those in control of photosynthesis, carbohydrate metabolism and assimilation, and cellulose and...

Carbon Sequestration: what really matters? - A reply to Buckeridge &amp;amp; Aidar

This is a reply to Buckeridge &amp;amp; Aidar's (2002) Point of View on the possible usefulness of GMOs (genetically modified organisms) built to increase carbon sequestration, and Plant Gene Therapy (PGT), particularly in rain forests, as future tools to reduce excessive atmospheric CO2. We argue that the alternatives to carbon sequestration they presented should not be treated as scientific or political priority, since their arguments have major ecological and socio-political flaws, such as ecological unpredictability, the existence of an already high potential for carbon sequestration by native non-manipulated plants, and the relevance of scientific and political sovereignty in regard to the global change issue.

A case of urethral carcinoma in 15-year-old mongrel male dog is described. Signs of dysuria, urethral obstruction, tenesmus, pain and cough were mentioned. Clinically, the animal was undernourished and showed signs of pain and bladder repletion during the palpation of the abdominal region. Other complementary exams were made such as routine urinalyses, X-ray, ultrassonography and measurement of blood urea and creatinine. Macroscopically, the mucous membrane of pelvic urethra was somewhat irregular, due to the presence of several small white irregular and ulcerated nodules of imprecise boundaries. Similar nodules were found in the lungs and heart. Histologically, transitional cell carcinoma of urethra with metastasis to lung and heart was detected.

Cardiovascular complications and increased levels of circulating modified low density lipoprotein in HIV patients and patients with lipodystrophy
Provedor de dados: 56
Autores: Ronchini,K.R.O.M.; Duarte,A.J.S.; Casseb,J.S.R.; Gidlund,M.
The introduction of highly active antiretroviral therapy (HAART) for patients infected with HIV has significantly prolonged the life expectancy and to some extent has restored a functional immune response. However, the premature introduction of HAART has led to a significant and alarming increase in cardiovascular complications, including myocardial infarction and the appearance of abnormal distribution of body fat seen as lipodystrophy. One key element in the development of ischemic coronary artery disease is the presence of circulating and tissue-fixed modified low density lipoprotein (mLDL) that contributes to the initiation and progression of arterial lesions and to the formation of foam cells. Even though not completely elucidated, the most likely...

Carotenoides en quimioprevención: Licopeno
Provedor de dados: 38
Autores: Vitale,Arturo Alberto; Bernatene,Eduardo Alberto; Pomilio,Alicia Beatriz.
Las frutas y hortalizas son una rica fuente de carotenoides que proporcionan beneficios para la salud debido a que disminuyen el riesgo de varias enfermedades, en particular, ciertos tipos de cáncer y enfermedades cardiovasculares y oculares, lo cual está corroborado por una extensa observación epidemiológica. Los carotenoides que han sido más estudiados en este sentido son beta-caroteno, licopeno, luteína y zeaxantina. La rápida y elevada cantidad de evidencias experimentales ha determinado que una dieta que contenga tomate o productos derivados del mismo, causa disminución de varios tipos de cáncer. Esto ha estimulado una amplia investigación de laboratorio y clínica, así como mucho entusiasmo comercial y público. Sin embargo, las evidencias son...

Case-case-control study of risk factors for nasopharyngeal colonization with methicillin-resistant Staphylococcus aureus in a medical-surgical intensive care unit
Provedor de dados: 55
Autores: Melo,Edson Carvalho de; Fortaleza,Carlos Magno Castelo Branco.
Nasopharyngeal colonization with methicillin-resistant Staphylococcus aureus (MRSA) often precedes the development of nosocomial infections. In order to identify risk factors for MRSA colonization, we conducted a case-case-control study, enrolling 122 patients admitted to a medical-surgical intensive care unit (ICU). All patients had been screened for nasopharyngeal colonization with S. aureus upon admission and weekly thereafter. Two case-control studies were performed, using as cases patients who acquired colonization with MRSA and methicillin-susceptible S. aureus (MSSA), respectively. For both studies, patients in whom colonization was not detected during ICU stay were selected as control subjects. Several potential risk factors were assessed in...

Cassava starch extraction effluent treatment in a one phase tubular horizontal pilot reactor with support medium
Provedor de dados: 70
Autores: Kuczman,Osvaldo; Tavares,Maria H. F.; Gomes,Simone D.; Guedes,Luciana P. C.; Grisotti,Geovane.
The cassava starch industries generate a large volume of wastewater effluent that, stabilized in ponds, wastes its biogas energy and pollutes the atmosphere. To contribute with the reversion of this reality, this manipueira treatment research was developed in one phase anaerobic horizontal pilot reactor with support medium in bamboo pieces. The reactor was excavated into the ground and sealed with geomembrane in HDPE, having a volume equal to 33.6 m³ and continuous feeding by gravity. The stability indicators were pH, volatile acidity/total alkalinity ratio and biogas production. The statistical analyses were performed by a completely randomized design, with answers submitted to multivariate analysis. The organical loads in COD were 0.556; 0.670; 0.678 and...

Catabolism of Ap4A and Ap5A by rat brain synaptosomes
Provedor de dados: 56
Autores: Emanuelli,T.; Bonan,C.D.; Sarkis,J.J.F.; Battastini,A.M.O.
Adenosine 5',5'''-P1,P4-tetraphosphate (Ap4A) and adenosine 5',5'''-P1,P5-pentaphosphate (Ap5A) are stored in and released from rat brain synaptic terminals. In the present study we investigated the hydrolysis of dinucleotides (Ap4A and Ap5A) in synaptosomes from the cerebral cortex of adult rats. Ap4A and Ap5A, but not Ap3A, were hydrolyzed at pH 7.5 in the presence of 20 mM Tris/HCl, 2.0 mM MgCl2, 10 mM glucose and 225 mM sucrose at 37oC. The disappearance of the substrates measured by FPLC on a mono-Q HR column was both time and protein dependent. Since synaptosome integrity was at least 90% at the end of the assay, hydrolysis probably occurred by the action of an ecto-enzyme. Extracellular actions of adenine dinucleotides at central nervous system...

Causes of hospitalization among extra-European Union children in a large hospital of Northern Italy, in a five-year observation period
Provedor de dados: 55
Autores: Sabbatani,Sergio; Baldi,Elena; Manfredi,Roberto.
The hospitalizations of 1,239 patients aged 14 years or less and immigrated from extra-European Union countries in Italy were assessed in the 6-year period, from 1999 to 2004. The main demographic and clinical features were analyzed according to several variables, also distiguishing patients aged less than one year, from those aged 1-14 years. The introduction of a deed of indemnity law in 2001 profoundly changed the pattern of admissions and health care needs and exploitation during subsequent years, leading to a massive regularization of clandestine immigrants.

CCR5 genotype and plasma ß-chemokine concentration of Brazilian HIV-infected individuals
Provedor de dados: 56
Autores: Mikawa,A.Y.; Tagliavini,S.A.; Costa,P.I.
The 32-bp deletion in the HIV-1 co-receptor CCR5 confers a high degree of resistance to HIV-1 infection in homozygous individuals for the deleted allele and partial protection against HIV-1 during disease progression in heterozygotes. Natural ligands for CCR5, MIP-1alpha, MIP-1ß and RANTES, have been shown to inhibit HIV replication in CD4+ T cells. In the present study, we examined the CCR5 genotype by PCR and the plasma levels of RANTES and MIP-1alpha by ELISA among blood donors (N = 26) and among HIV-1-infected individuals (N = 129). The control group consisted of healthy adult volunteers and HIV-1-infected subjects were an asymptomatic and heterogeneous group of individuals with regard to immunologic and virologic markers of HIV-1 disease.

Autores: Costa,F.A.L.; Guerra,J.L.; Silva,S.M.M.S.; Klein,R.P.; Mendonça,I.L.; Goto,H.
Renal involvement in visceral leishmaniasis (VL) is very frequent. The renal lesions of humans and dogs are similar but their pathogenesis has not been clearly elucidated. There is growing evidence that the cellular immune response is involved in the pathogenesis of immunologically mediated glomerulonephritis. Since T cells could participate in the pathogenesis of nephropathy, in the present study we investigated the possible involvement of CD4+ and CD8+ T cells in the nephropathy of canine VL. Six dogs naturally infected with Leishmania (Leishmania) chagasi from the endemic area in the Northeast of Brazil, the town of Teresina in the State of Piauí, were studied. An expressive inflammatory infiltrate of CD4+ T cells both in glomeruli and in interstitium...

We investigated the effectiveness of celecoxib in reducing symptoms in patients with difficult chronic pelvic pain syndrome (CPPS), NIH category IIIA. Sixty-four patients with category IIIA CPPS were randomized into two groups of 32 subjects each. One group was treated with celecoxib (200 mg daily) and the other with placebo. All patients underwent treatment for 6 weeks and were evaluated clinically before (baseline) and after 1, 2, 4, 6, and 8 weeks of treatment. The evaluation included the NIH Chronic Prostatitis Symptom Index (NIH-CPSI) and a subjective global assessment (SGA). Repeated measures analysis of variance was used to evaluate treatment and time effects and their interaction. A decrease (means ± SD) in total NIH-CPSI score from 23.91 ± 5.27 to...

Cell fusion and chromatin degeneration in an inbred line of maize
Provedor de dados: 74
Autores: Caetano-Pereira,Creuci Maria; Pagliarini,Maria Suely; Brasil,Edward Madureira.
A large number of maize genotypes are currently being evaluated to determine the effect of environmental stress caused by the aluminum found in cerrado soils on meiotic behavior. In the present study we report the occurrence of cell fusion followed or not by chromatin degeneration in meiocytes of some plants of an inbred line of maize grown on acid and corrected soil in the Brazilian central plateau. The results suggest the absence of any soil effect on the irregularities observed since the number of affected plants was higher among those grown on corrected soil. The possible causes of these irregularities and their influence on male sterility are discussed.

We have demonstrated that acute third ventricle injections of lead acetate (PbAc) exert a powerful antidipsogenic effect and induce a significant increase in renal sodium excretion. In the present study we confirm the antidipsogenic effect of lead and demonstrate that central administration of this metal, in minute amounts, significantly reduces salt intake both during dehydration and after central angiotensinergic stimulation. Adult male Wistar rats had the third ventricle cannulated seven days before the experiments. During this period they had free access to distilled water and hypertonic saline solution (1.5%). After a 24-h period of fluid deprivation, experimental animals received third ventricle injections of PbAc (0.3, N = 8 and 3.0 nmol/rat, N =...

ABSTRACT Bloodstream and venous catheter-related corynebacterial infections in paediatric patients with haematological cancer were investigated from January 2003 to December 2014 at the Brazilian National Cancer Institute in Rio de Janeiro, Brazil. We observed that during cancer treatment, invasive corynebacterial infections occurred independent of certain factors, such as age and gender, underlying diseases and neutropenia. These infections were ssscaused by Corynebacterium amycolatum and other non-diphtherial corynebacteria. All cases presented a variable profile of susceptibility to antimicrobial agents, except to vancomycin. Targeted antibiotic therapy may contribute to catheters maintenance and support quality of treatment. Non-diphtherial...

Provedor de dados: 59
Autores: Raddi,Maria Stella G.; Lorencetti,Nancy C.
Microbiological routine exams of endocervix and vaginal specimens of 22 women with clinical history of recent spontaneous abortion or premature rupture of membranes were accomplished. Chlamydia trachomatis, Streptococcus pyogenes, Streptococcus agalactiae, Candida sp and Gardnerella vaginalis were recovered from 54.5% (12) of the women. Ureaplasma urealyticum was frequently isolated (45.5%) but 5 out of 22 had U. urealyticum only. Our report stands for the importance of quantitative as well as qualitative investigation on genital microflora in pregnant women, since it is likely to influence on pregnancy outcome.

Autores: Chaves,A.C.; Pinto,R.N.; Lourenço,M.T.; Mari,J.J.
The prevalent rate of psychiatry morbidity amongst patients with cancer reported in various studies ranges from 5 to 50%, a variation that can be attributed to differences in sample size, the disease itself and treatment factors. The objectives of the present study were to determine the frequency of psychiatric morbidity amongst recently diagnosed cancer outpatients and try to identify which factors might be related to further psychological distress. Two hundred and eleven (70.9%) female patients and 87 (29.1%) male patients from the chemotherapy unit of the Cancer Hospital A.C. Camargo (São Paulo) completed a questionnaire that featured data on demographic, medical and treatment details. The Self Reporting Questionnaire (SRQ-20) was administered to the...

In contrast to most developed countries, most patients with primary hyperparathyroidism in Brazil are still symptomatic at diagnosis. However, we have been observing a change in this pattern, especially in the last few years. We evaluated 104 patients, 77 females and 27 males aged 11-79 years (mean: 54.4 years), diagnosed between 1985 and 2002 at a University Hospital. Diagnosis was made on the basis of clinical findings and of high total and/or ionized calcium levels, high or inappropriate levels of intact parathyroid hormone and of surgical findings in 80 patients. Patients were divided into three groups, i.e., patients diagnosed from 1985 to 1989, patients diagnosed from 1990 to 1994, and patients diagnosed from 1995 to 2002. The number of new cases...

Changes of ongoing activity in Cebus monkey perirhinal cortex correlate with behavioral performance
Provedor de dados: 56
Autores: Lima,B.; Fiorani,M.; Gattass,R.
A Cebus apella monkey weighing 4 kg was trained in a saccadic eye movement task and while the animal performed the task we recorded the extracellular activity of perirhinal cortical neurons. Although the task was very simple and maintained at a constant level of difficulty, we observed considerable changes in the performance of the monkey within each experimental session. The behavioral states responsible for such variation may be related to arousal, motivation or attention of the animal while engaged in the task. In approximately 20% (16/82) of the units recorded, long-term direct or inverse correlations could be demonstrated between the monkey's behavioral state and the cells' ongoing activity (independent of the visual stimulation or of the specific...

After the advent of HAART, the clinical course of HIV infection has dramatically improved. Therefore, it seems appropriate to reevaluate the performance of bone marrow biopsy (BMB) as a diagnostic tool. The aim of the present study was to compare the reasons for performing a BMB and its diagnostic yield in HIV-patients before and after HAART. A total of 165 BMB specimens obtained from HIV-infected patients receiving care at the Hospital of Universidade Federal do Rio de Janeiro in two different periods (1986-1994 and 1999-2004) were analysed. The main reason for BMB examination in the first period was fever (88%), which decreased in the second period (57%, p &lt; 0.0001), when cytopenia (51%) was the leading reason for BMB, whereas in the first period it...

Characterization of angiotensin-converting enzymes 1 and 2 in the soleus and plantaris muscles of rats
Provedor de dados: 56
Autores: Fernandes,T.; Hashimoto,N.Y.; Oliveira,E.M.
Angiotensin-converting enzymes 1 (ACE1) and 2 (ACE2) are key enzymes of the renin-angiotensin system, which act antagonistically to regulate the levels of angiotensin II (Ang II) and Ang-(1-7). Considerable data show that ACE1 acts on normal skeletal muscle functions and architecture. However, little is known about ACE1 levels in muscles with different fiber compositions. Furthermore, ACE2 levels in skeletal muscle are not known. Therefore, the purpose of this study was to characterize protein expression and ACE1 and ACE2 activities in the soleus and plantaris muscles. Eight-week-old female Wistar rats (N = 8) were killed by decapitation and the muscle tissues harvested for biochemical and molecular analyses. ACE1 and ACE2 activities were investigated by a...

Provedor de dados: 56
The presence of inhibitory nonadrenergic noncholinergic (NANC) intrinsic innervation of the circular muscle of the gastrointestinal sphincters of the South American (SA) opossum was investigated in vitro. Isolated circular muscle strips from the esophagogastric and ileocolonic junctions but not from the gastroduodenal (pylorus) region developed spontaneous tension. Tetrodotoxin (TTX, 1 µM) augmented the spontaneous tension only in the ileocolonic junction strips. Electrical field stimulation of esophagogastric and ileocolonic junction strips caused frequency-dependent responses consisting of a relaxation at lower frequencies (&amp;lt;1 Hz) and a biphasic response or contraction at higher frequencies. In the strips from the pyloric region electrical field...

Characterization of ribosomal DNA (rDNA) in Drosophila arizonae
Provedor de dados: 74
Autores: Javier Tovar,Francisco; Silva,Luiz Antônio Ferreira da; Rodarte,Renato Santos; Leoncini,Orilio.
Ribosomal DNA (rDNA) is a multigenic family composed of one or more clusters of repeating units (RU). Each unit consists of highly conserved sequences codifying 18S, 5.8S and 28S rRNA genes intercalated with poorly conserved regulatory sequences between species. In this work, we analyzed the rDNA of Drosophila arizonae, a member of the mulleri complex (Repleta group). Using genomic restriction patterns, cloning and mapping of some representative rDNA fragments, we were able to construct a representative restriction map. RU in this species are 13.5-14 kb long, restriction sites are completely conserved compared with other drosophilids and the rDNA has an R1 retrotransposable element in some RU. We were unable to detect R2 elements in this species.

Characterization of the interdependency between residues that bind the substrate in a β-glycosidase
Provedor de dados: 56
Autores: Tomassi,M.H.; Rozenfeld,J.H.K.; Gonçalves,L.M.; Marana,S.R.
The manner by which effects of simultaneous mutations combine to change enzymatic activity is not easily predictable because these effects are not always additive in a linear manner. Hence, the characterization of the effects of simultaneous mutations of amino acid residues that bind the substrate can make a significant contribution to the understanding of the substrate specificity of enzymes. In the β-glycosidase from Spodoptera frugiperda (Sfβgly), both residues Q39 and E451 interact with the substrate and this is essential for defining substrate specificity. Double mutants of Sfβgly (A451E39, S451E39 and S451N39) were prepared by site-directed mutagenesis, expressed in bacteria and purified using affinity chromatography. These enzymes were characterized...

Sprouting or germination in wheat takes place as a result of the rupture of the dormancy in grain, expressed in physiological terms as the increase of &amp;#945;-amylases and proteases activity, which has been associated with low values of falling number. Grain sprouting has been related with high moisture and temperature at harvest and it is a serious problem in the north of Argentina. The objectives of this study were to characterize introduced and local wheat cultivars for sprouting response through falling number and, tentatively, to identify adapted materials with good behavior for this trait. A set of thirty introduced and local late and early heading wheat varieties was tested through falling number in two experiments conducted at Marcos Juárez,...

ABSTRACT  Fruits of the Brazilian cerrado usually have typical flavor and high levels of nutrients; however, many of these fruits are little known and marketed. The aim of this study was to chemically and bioactively characterize guapeva fruit, according to standard methodologies. Guapeva has high moisture (65 %) and minerals (1%) content and significant content of phenolic compounds (220 GAE/100g) and consequent antioxidant activity (329.29 µmol/ Trolox eq). This fruit has desirable features to compose a healthy diet and should be further explored in research and economically.

Chill-induced changes in fatty acid composition of tonoplast vesicles from hypocotyls of Vigna unguiculata (L.) Walp.
Provedor de dados: 61
Autores: Oliveira,Luciana M. N. de; Sobreira,Alana C. de M.; Monteiro,Fernando de P.; Melo,Dirce F. de.
The present study was undertaken to investigate the changes induced by chilling on fatty acid composition of tonoplast vesicles from hypocotyls of Vigna unguiculata (L.) Walp. The 7 day-old control seedlings were grown at 25°C while treated seedlings were submitted to low temperatures (10°C and 4°C) for 4 days after 3 days germination. The chilling stress resulted in a differential inhibition of plant growth at 10°C and 4°C. Following chilling at 10°C and 4°C, the rate of unsaturated to saturated fatty acids increased under chilling stress. Our results suggest that the increase of unsaturated fatty acids content as well as the higher rate unsaturated/saturate fatty acidsmight be used by V. unguiculata plants as an adaptation mechanism likely to maintain...

Cholesterol changes the fatty acid composition of rat enterocytes
Provedor de dados: 56
Autores: Gazzola,J.; Martins,E.F.; Miyasaka,C.K.; Palanch,A.C.; Vecchia,M.G.; Curi,R.
The effect of free cholesterol on the fatty acid composition and growth of rat fetal enterocytes was investigated in the absence and presence of 10% (v/v) fetal calf serum. Cholesterol caused a significant reduction of cell number after 6 and 12 h in culture. The fatty acid composition of enterocytes cultured in the presence of serum was also changed by the presence of 20 µM cholesterol. The fatty acid profile was determined by HPLC using fluorescence detection (325 nm excitation and 395 nm emission). Cholesterol (20 µM) increased the proportion (given in percentage of the total fatty acids) of the following fatty acids in cultured cells: lauric (by 42%), oleic (by 34%), linoleic (by 44%) and gamma-linolenic (by 20%) acids and reduced the proportion of...

Chromosomal damage in air crew members of international flights: A preliminary report
Provedor de dados: 74
Autores: Picco,S.J.; De Luca,J.C.; MacIntyre,C.; Dulout,F.N.
Air crew members of international flights are exposed to ionizing radiations originated from the collision of cosmic particles with atoms of the atmosphere. The degree of exposure varies according to the altitude, latitude, and solar activity. The cytogenetical analysis showed a significant increase of dicentric chromosomes (14.5 ± 0.76 per 1,000 cells) in active air crew members as well as in retired air crew members (7.5 ± 0.59 per 1,000 cells) in relation to controls (0.5 ± 0.05 per 1,000 cells). In active members the frequency of ring chromosomes was also increased (2.0 ± 0.31 per 1,000 cells) but not found in retired crew members. These observations suggest a high degree of exposure to ionizing radiations of air crew personnel. Consequently, the...

Autores: Ogliari,Juliana Bernardi; Guimarães,Marco Antônio; Camargo,Luis Eduardo Aranha.
We used 125 microsatellite markers to genotype the maize (Zea mays L.) near isogenic lines (NIL) L30HtPHtPRtRt and L30htphtpRtRt and the L40htphtprtrt line which contrast regarding the presence of the recently described dominant HtP and the recessive rt genes that confer resistance to Exserohilum turcicum. Five microsatellite markers revealed polymorphisms between the NIL and were considered candidate linked markers for the HtP resistance gene. Linkage was confirmed by bulked segregant sample (BSS) analysis of 32 susceptible and 34 resistant plants from a BC1F1 population derived from the cross (L30HtPHtPRtRt x L40htphtprtrt) x L40htphtprtrt. The bnlg198 and dupssr25 markers, both located on maize chromosome 2L (bin 2.08), were polymorphic between bulks....

Autores: Carvalho de Souza,Patrícia; Salim Khayat,André; Chamon Seligmann,Igor; Rodríguez Burbano,Rommel Mario.
The collared peccary (Tayassu tajacu) is widely distributed over the American continent, being found from the south of the USA to the north of Argentina. In Brazil, it is spread all over the country, being one of the potential species to be raised in captivity. Therefore, the cytogenetic techniques could be a potential tool for reproductive monitoring of animals raised in captivity, mainly when destined for commercial purposes. This study had the objective of determining the chromosome number of two populations raised in captivity and characterizing them by GTG banding. For this purpose, an analysis was made of mitotic metaphases obtained from lymphocyte cultures made from blood samples of 11 animals, six of which from the Northeast and five from the North...

Chromosome number in germplasm accessions of Paspalum notatum (Gramineae)
Provedor de dados: 54
Chromosome numbers are reported for 127 germplasm accessions of Paspalum notatum maintained by EMBRAPA (Empresa Brasileira de Pesquisa Agropecuária) in two research centers in Brazil. Most accessions were collected in their natural habitats in Southern Brazil. Tetraploidy (2n = 40 chromosomes) was predominant (91% of the accessions studied), confirming previous reports for the species. Eleven accessions with 2n = 20 chromosomes, although collected in the wild, are possibly derived from 'Pensacola' bahiagrass, commonly cultivated in the area since its introduction from the United States in the 60's, for the establishment of permanent pastures.

Chromosome polymorphism in Ctenomys minutus (Rodentia-Octodontidae)
Provedor de dados: 54
A sample of 101 specimens of Ctenomys minutus was collected along its geographic range. Eight karyotypes (2n = 42, 45, 46a, 46b, 47, 48, 49 and 50) were found. The chromosome polymorphisms were due to Robertsonian rearrangements and tandem fusions. The distribution of polymorphisms indicated three population blocks: northern (2n = 49 and 50), central (2n = 46a, 47, and 48) and southern (2n = 42, 45, and 46b). These findings suggest that this species is undergoing a speciation process due to geographic isolation.

Chromosome sensitivity to bleomycin in G2 lymphocytes from Down syndrome patients
Provedor de dados: 54
Several studies have demonstrated that lymphocytes from patients with Down syndrome (DS) exhibit an increased frequency of chromosome aberrations when they are exposed to ionizing radiation or to chemicals at the G0 or G1 phases of the cell cycle, but not at G2, when compared to normal subjects. To determine the susceptibility of DS lymphocytes at G2 phase, bleomycin, a radiomimetic agent, was used to induce DNA breaks in blood cultures from 24 Down syndrome patients. All the patients with DS showed free trisomy 21 (47,XX + 21 or 47,XY + 21). Individuals that showed an average number of chromatid breaks per cell higher than 0.8 were considered sensitive to the drug. No control child showed susceptibility to bleomycin, and among the 24 patients with DS,...

Circadian rhythms in blood pressure in free-ranging three-toed sloths (Bradypus variegatus)
Provedor de dados: 56
Autores: Duarte,D.P.F.; Silva,V.L.; Jaguaribe,A.M.; Gilmore,D.P.; Da Costa,C.P.
Blood pressure (BP) profiles were monitored in nine free-ranging sloths (Bradypus variegatus) by coupling one common carotid artery to a BP telemetry transmitter. Animals moved freely in an isolated and temperature-controlled room (24ºC) with 12/12-h artificial light-dark cycles and behaviors were observed during resting, eating and moving. Systolic (SBP) and diastolic (DBP) blood pressures were sampled for 1 min every 15 min for 24 h. BP rhythm over 24 h was analyzed by the cosinor method and the mesor, amplitude, acrophase and percent rhythm were calculated. A total of 764 measurements were made in the light cycle and 721 in the dark cycle. Twenty-four-hour values (mean ± SD) were obtained for SBP (121 ± 22 mmHg), DBP (86 ± 17 mmHg), mean BP (MBP, 98 ±...

Circulating forms of parathyroid hormone detected with an immunofluorometric assay in patients with primary hyperparathyroidism and in hyperparathyroidism secondary to chronic renal failure
Provedor de dados: 56
Autores: Kunii,I.S.; Vieira,J.G.H.
In patients with uremia, intact parathyroid hormone (PTH) measurement appears to overestimate the biologically active hormone in circulation. The recent description of the accumulation in these patients of a non-intact PTH form measured by the standard immunometric assays, re-opened the question. In this study we submitted serum samples from 7 patients with primary hyperparathyroidism (PHP) and from 10 patients with hyperparathyroidism secondary to chronic renal failure (SHP) to preparative HPLC in order to discriminate the molecular forms measured by our currently used immunofluorometric assay for intact PTH. The elution profile obtained with the HPLC system showed two clearly defined peaks, the first one corresponding to a lower molecular weight form,...

The aim of this work was to verify the occurrence of bovine and swine cysticercosis in animals slaughtered at the Abatedouro Municipal de Sabáudia, Paraná State. The number of daily-abated animals, the number of animals with cysticercus and the number and location of the cysticercus in the animals in a period of twelve months were collected. From 1046 swines slaughtered none showed cysticercus, but 36/out of 389 bovines (9.3%) were contaminated. Head was the most parasited region, followed by heart, tongue and liver. The absence of contamination observed in swines and the low contamination of the bovines reinforce the efficiency of the control measures accomplished in Paraná State.

Citations to papers from Brazilian institutions: a more effective indicator to assess productivity and the impact of research in graduate programs
Provedor de dados: 56
Autores: Meneghini,R.
A recent assessment of 4400 postgraduate courses in Brazil by CAPES (a federal government agency dedicated to the improvement of the quality of and research at the postgraduate level) stimulated a large amount of manifestations in the press, scientific journals and scientific congresses. This gigantic effort to classify 16,400 scientific journals in order to provide indicators for assessment proved to be puzzling and methodologically erroneous in terms of gauging the institutions from a metric point of view. A simple algorithm is proposed here to weigh the scientometric indicators that should be considered in the assessment of a scientific institution. I conclude here that the simple gauge of the total number of citations accounts for both the productivity...

Clastogenic effects of different Ureaplasma urealyticum serovars on human chromosomes
Provedor de dados: 56
The possibility that Ureaplasma urealyticum might play an important role in human infertility was first raised more than 20 years ago, but this association remains speculative. Considering the hypothesis that the pathogenicity of Ureaplasma urealyticum may depend on its serotypes, the clastogenic effects of different strains of Ureaplasma urealyticum, at concentrations of 103 CCU (color changing units)/ml, 104 CCU/ml and 105 CCU/ml, were evaluated in vitro in short-term cultures of human lymphocytes. Total or partial mitotic inhibition was produced by Ureaplasma urealyticum serotypes 2, 3 and 10 independent of the concentration (103 CCU/ml, 104 CCU/ml or 105 CCU/ml) of the microorganisms employed. In contrast, the clastogenic effects observed with...

Clearing and dissecting insects for internal skeletal morphological research with particular reference to bees
Provedor de dados: 92
Autores: Porto,Diego Sasso; Melo,Gabriel A.R.; Almeida,Eduardo A.B.
ABSTRACT A detailed protocol for chemical clearing of bee specimens is presented. Dry specimens as well as those preserved in liquid media can be cleared using this protocol. The procedure consists of a combined use of alkaline solution (KOH or NaOH) and hydrogen peroxide (H2O2), followed by the boiling of the cleared specimens in 60–70% EtOH. Clearing is particularly useful for internal skeletal morphological research. This procedure allows for efficient study of internal projections of the exoskeleton (e.g., apodemes, furcae, phragmata, tentoria, internal ridges and sulci), but this process makes external features of the integument, as some sutures and sulci, readily available for observation as well. Upon completion of the chemical clearing process the...

Climatic changes: what if the global increase of CO2 emissions cannot be kept under control?
Provedor de dados: 56
Autores: Barreto de Castro,L.A.
Climatic changes threaten the planet. Most articles related to the subject present estimates of the disasters expected to occur, but few have proposed ways to deal with the impending menaces. One such threat is the global warming caused by the continuous increase in CO2 emissions leading to rising ocean levels due to the increasing temperatures of the polar regions. This threat is assumed to eventually cause the death of hundreds of millions of people. We propose to desalinize ocean water as a means to reduce the rise of ocean levels and to use this water for populations that need good quality potable water, precisely in the poorest regions of the planet. Technology is available in many countries to provide desalinated water at a justifiable cost...

El melanoma es un tumor maligno originado en los melanocitos, cuya incidencia y mortalidad han aumentado en las últimas décadas. Sus factores de riesgo más importantes son la susceptibilidad genética relacionada con sensibilidad al sol (capacidad para broncearse y tendencia a las quemaduras) y con ciertos genes especíLcos; factores ambientales tales como la exposición a la radiación UV, latitud y una combinación de ambos, como la cantidad de nevos. Sus formas clínicas son: melanoma extensivo superLcial (70%), nodular (15-30%), lentigo maligno (10-15%) y acrolentiginoso (5%). De todas las características histológicas, el espesor de Brelow (medido en mm desde la granulosa hasta el punto más profundo de penetración tumoral) es el predictor de sobrevida más...

Limited information is available regarding AmpC β-lactamase (ABL)-producing Enterobacteriaceae compared to extended-spectrum β-lactamase-producing enterobacteria. Since ABL-producing organisms are often resistant to multiple antimicrobial agents, therapeutic options against these pathogens are limited. Among 230 clinical Enterobacteriaceae isolates, 64 (27.8%) were found to produce ABL in our study. Escherichia coli (83.9%) was a predominant pathogen, followed by Citrobacter freundii (5.2%). A significant proportion of ABL-producing isolates (81.3%) were found to be multidrug resistant against commonly used antibiotics. Univariate analysis showed that prior history of taking antibiotics (odds ratio [OR], 5.278; confidence interval [CI], 2.838-9.817; p &lt;...

Autores: Ferraro,G. C.; Moraes,J. R. E.; Pereira,G. T.; Moraes,F. R.; Bueno de Camargo,M. H.
The aim of this study was to evaluate the effect of snake venom derived fibrin glue on the healing of the deep digital flexor tendon, during three periods. The tendon of the 2nd digit of 30 thoracic limbs of dogs was partially sectioned for glue application. Biopsies were performed 7, 15, and 30 days post surgery for the clinical and morphological study of tendons. Analysis of the results showed that 73.3% of the tendons showed stump retraction and 16.6% moderate to excessive adherence, which affected sliding. There was a significant difference in the number of inflammatory cells among the three studied periods, being the highest on day 15. The morphological analysis revealed a typical tendon healing process with a lower level of inflammation in the acute...

Descrevem-se seis casos de alteração fibroadenomatosa mamária felina (AFAMF) associada à administração de uma única injeção de acetato de medroxiprogesterona (AMP) na dose recomendada pelos fabricantes. A doença foi observada em gatas jovens não-castradas atendidas em dois hospitais veterinários de 1999 a 2001. O diagnóstico de AFAMF foi feito com base no histórico, sinais clínicos e achados macroscópicos e confirmado histologicamente em quatro dos seis casos. Sugere-se que a ocorrência da AFAMF esteja associada ao efeito prolongado de uma única injeção de AMP de depósito administrada em situações nas quais o emprego dessa terapia não é recomendado.

Enterococcus spp bacteremia is associated with high mortality and the appearance of high-level gentamicin resistance (HLGR) created additional challenges for the treatment of these infections. We evaluated the epidemiological and clinical characteristics of patients with bacteremias caused by HLGR and non_HLGR Enterococcus faecalis isolates at a teaching hospital in the State of São Paulo, Brazil. Patients with bacteremia due to E. faecalis diagnosed between January 1999 and December 2003 were included in the study. We collected clinical, epidemiological, and microbiological data from medical records. Banked isolates were typed using pulsed-field gel electrophoresis. We identified 145 cases of E. faecalis bacteremia: 66 (45.5%) were caused by HLGR isolates...

Nosocomial dissemination of glycopeptide-resistant enterococci represents a major problem in hospitals worldwide. In Brazil, the dissemination among hospitals in the city of São Paulo of polyclonal DNA profiles was previously described for vancomycin-resistant Enterococcus faecium. We describe here the dissemination of VanA phenotype E. faecalis between two hospitals located in different cities in the State of São Paulo. The index outbreak occurred in a tertiary care university hospital (HCUSP) in the city of São Paulo and three years later a cluster caused by the same strain was recognized in two patients hospitalized in a private tertiary care hospital (CMC) located 100 km away in the interior of the state. From May to July 1999, 10 strains of...

ABSTRACT Vancomycin-resistant Enterococcus faecium (VREfm) has emerged as an important global nosocomial pathogen, and this trend is associated with the spread of high-risk clones. Here, we determined the genetic and phenotypic features of 93 VREfm isolates that were obtained from patients in 13 hospitals in Vitória, Espírito Santo, Brazil, during 2012-2013. All the isolates were vancomycin-resistant and harbored the vanA gene. Only 6 (6.5%) of the VREfm isolates showed the ability to form biofilm. The 93 isolates analyzed belong to a single pulsed-field gel electrophoresis lineage and presented six subtypes.

Cloning of a chitinase gene from Ewingella americana, a pathogen of the cultivated mushroom, Agaricus bisporus
Provedor de dados: 74
Autores: Inglis,P.W.; Peberdy,J.F.; Sockett,R.E.
We have isolated a gene encoding a chitinase (EC 3.2.1.14) from Ewingella americana, a recently described pathogen of the mushroom Agaricus bisporus. This gene, designated chiA (EMBL/Genbank/DDBJ accession number X90562), was cloned by expression screening of a plasmid-based E. americana HindIII genomic library in Escherichia coli using remazol brilliant violet-stained carboxymethylated chitin incorporated into selective medium. The chiA gene has a 918-bp ORF, terminated by a TAA codon, with a calculated polypeptide size of 33.2 kDa, likely corresponding to a previously purified and characterised 33-kDa endochitinase from E. americana. The deduced amino acid sequence shares 33% identity with chitinase II from Aeromonas sp. No. 10S-24 and 7.8% identity with...

Clostridium difficile contamination in retail meat products in Brazil
Provedor de dados: 55
Autores: Pires,Renata N.; Caurio,Cassia F.B.; Saldanha,Gabriele Z.; Martins,Andreza F.; Pasqualotto,Alessandro C.
ABSTRACT  Introduction Clostridium difficile is an important cause of diarrhoea, particularly in patients receiving antibiotic therapy. Recent studies have shown that a substantial proportion of C. difficile infections are acquired in the community, as a zoonotic disease. Brazil is a large exporter of meat and so far no study has evaluated meat contamination with C. difficile spores.  Methods Here we analysed 80 retail meat products purchased from local supermarkets in a Brazilian metropolis (Porto Alegre, Southern Brazil). Samples from these products were grown in anaerobic conditions, and tested with a real time polymerase chain reaction test.  Results Contamination with C. difficile spores was not found in the study. Bacteria isolated from meat included...

Cockayne syndrome: report of a Brazilian family with confirmation of impaired RNA synthesis after UV-irradiation
Provedor de dados: 74
Autores: Karam,Simone M.; Costa,Jaderson C.; Jardim,Laura; Pires,Ricardo F.; Lehmann,Alan R.; Giugliani,Roberto.
Cockayne syndrome (CS) is an autosomal recessive disorder characterized by dwarfism, growth deficiency, neurological deterioration, skin photosensitivity and a characteristic progressive facial appearance. In the present study we report the first Brazilian CS family in which diagnosis was confirmed by the demonstration of decreased RNA synthesis in cultured fibroblasts exposed to UV-C radiation. Despite the progressive course of the disease and the unavailability of an effective treatment, diagnosis may be very important for the benefits to be gained by the afflicted family from genetic counseling and/or prenatal diagnosis.

COD, TSS, nutrients and coliforms removals in UASB reactors in two stages treating swine wastewater
Provedor de dados: 70
Autores: Ramires,Roseane Del'Arco; Oliveira,Roberto Alves de.
The performance of two upflow anaerobic sludge blanket (UASB) reactors was evaluated in pilot scale (908 and 188 L), installed in series (R1 and R2), fed with swine wastewater with TSS around 5 and 13 g L-1. The UASB reactors were submitted to HDT of 36 and 18 h with VOL of 5.5 to 34.4 g COD (L d)-1 in the R1 and HDT of 7.5 e 3.7 h with VOL from 5.1 to 45.2 g COD (L d)-1 in the R2. The average removal efficiencies of COD ranged from 55 to 85% in the R1 and from 43 to 57% in the R2, resulting in values from 82 to 93% in the UASB reactors in two stage. Methane concentrations in the biogas were 69 to 74% with specific production from 0.05 to 0.27 L CH4 (g removedCOD)-1 in the R1 and of 0.10 to 0.12 L CH4 (g removedCOD)-1 in the R2. The average removal...

Co-evolution model of Colletotrichum lindemuthianum (melanconiaceae, melanconiales) races that occur in some Brazilian regions
Provedor de dados: 74
Autores: Alzate-Marin,Ana Lilia; Barros,Everaldo Gonçalves de; Moreira,Maurílio Alves.
Colletotrichum lindemuthianum, the causal agent of anthracnose in the common bean (Phaseolus vulgaris L.), displays a high level of virulence diversity, which explains the large number of existing pathotypes. Several lines of evidence indicate that such diversity is, at least in part, due to plant and pathogen co-evolution. A co-evolution model based on the binary classification of 25 races identified in Brazil by inoculation of differential cultivars and random amplified polymorphic DNA (RAPD) data is proposed. In this model, races 8 and 64 that infected bean cultivar Cornell 49-242 (Are gene) and Mexico 222 (Mexico I gene) are considered to be sources of two important evolutionary routes. Inferences about undescribed races from Brazil could be made.

ABSTRACT The biotechnology used in tendon, bone and joint recoveries in Equine Medicine has improved in recent years. The most used are platelet rich plasma and stem cells from adipose tissue and bone marrow. However, recent studies have shown that stem cells can be found in the bloodstream, also named peripheral blood progenitor cells (CPP). This note aims at reporting the feasibility of automated collection of CPP in horses. The procedure was conducted in an equine, female, Quarter Horses, 2 years old, 385kg. The automated collection of CPP was conducted using apheresis equipment Fresenius- Kabi coupled to C4Y kit. The procedure lasted two hours and 30 minutes without complications, processing 5054mL of whole blood and obtaining 351mL of CPP. Upon...

Autores: Dieter,Tatiana; Matte,Ursula da Silveira; Schwartz,Ida Vanessa; Tomatsu,Shunji; Giugliani,Roberto.
Morquio A Syndrome (mucopolysaccharidosis IVA - MPS IVA, OMIM# 253000) is an autosomal recessive inborn error of metabolism caused by the deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS). We investigated five unrelated Brazilian MPS IVA families for mutations in exons 4, 5, 9 and 10 of the GALNS gene. Six out of the 10 mutant alleles were identified. Taken together with a previous study, which included six unrelated families, common mutations among Brazilian patients were p.N164T, p.G116S and p.G301C. Among one hundred control subjects three novel silent mutations were found (p.A107A; GCC -&gt; GCT, p.Y108Y; TAC -&gt; TAT, p.P357P; CCG -&gt; CCA). Screening starting with exons 4, 5, 9, 10 and 11 may be a good strategy for genotyping of...

Provedor de dados: 49
Autores: Gnocchi,Ariana Pignaton; Srbek-Araujo,Ana Carolina.
Abstract There are few studies on the diet of Common Vampire Bat (Desmodus rotundus), despite its wide geographic distribution. The species is considered exclusively hematophagous, and medium and large-sized mammals are their main prey. In this study we report evidences of Common Vampire Bat feeding on Lowland Tapir (Tapirus terrestris) in a protected area located in the north of the state of Espírito Santo, southeastern Brazil, from camera trap records. The bat tried to access the Lowland Tapir by the posterior dorsolateral side of the body, and used the mean stratum of the vegetation as a point of support and observation between the consecutive offensives on the prey. In the same reserve, there were also two events of bat offensives on domesticated ox...

Abstract Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) have increasingly been reported in healthy communities. This study aimed to assess the rate of S. aureus in general and MRSA in particular from nasal secretion of children in daycare centers in Vitória da Conquista, Brazil. The isolates were identified based on morphology, biochemical tests and by PCR. Detection of virulence genes, biofilm production, and susceptibility test by disk diffusion agar were performed. MRSA isolates were characterized by spa, SCCmec, and multilocus sequence typing (MLST). S. aureus were recovered from 70 (47.3%) of 148 children. Among the 11 MRSA strains (15.7%), two SCCmec types (IV and V) were detected. MLST identified four STs related to three...

Autores: Oliveira,Luiz F. C. de; Fioreze,Ana P.; Medeiros,Antonio M. M.; Silva,Mellissa A. S.
A falta de registro de dados de precipitação em estações pluviométricas relativa a problemas com os aparelhos de coleta e a ausência do operador em determinadas épocas, comprometem a continuidade das informações. Para que se possa aplicar um tratamento estatístico em uma série histórica de precipitação deve-se proceder ao preenchimento das falhas existentes. Os métodos mais usuais nesta etapa são: ponderação regional (PR), regressões linear (RM) e potencial (RP) múltiplas, ponderação regional com base em regressões lineares (RS) e vetor regional (VR). Empregando-se séries históricas de precipitação total anual com 22 anos de observação para 6 estações pluviométricas localizadas no Estado de Goiás, fez-se uma análise comparativa entre os métodos de...

Comparação entre métodos de avaliação de transmissão de Pyricularia grisea através de sementes em triticale
Provedor de dados: 102
Autores: Martins,Thais Dias; Lavorenti,Norberto A.; Urashima,Alfredo S.
Triticale (X. triticosecale) é o mais novo hospedeiro de Magnaporthe grisea (Pyricularia grisea), agente causal da brusone, no estado de São Paulo. Extensas áreas da cultura no sul do estado sofreram severas perdas no ano de 2001. Especula-se que sementes infetadas tenham sido de vital importância na ocorrência e disseminação do fungo. Entretanto, a transmissão do patógeno das sementes para plântulas ainda é motivo de controvérsia, tanto para brusone do arroz (Oryza sativa) como para brusone do trigo (Triticum aestivum). Um dos fatores para tal controvérsia pode estar nos métodos empregados nos diferentes estudos. O presente trabalho visou examinar a transmissão de P. grisea a partir de sementes de triticale, através de quatro diferentes metodologias, com...

DNA samples of six bovines obtained from three tissues (blood, semen and hair) were extracted using two different techniques. After the extraction procedures the samples were divided in six fractions. Three were stored at -20° C and three at 4° C. Every three months one sample of each tissue/extraction procedure was analyzed in spectrophotometer, to determine the quantity of the DNA and the extract was amplified using the primer RM 29. No differences in the DNA quantity or in the level of protein contamination among the three periods of analyses were observed. All the DNA extracted by quick extraction technique showed good amplification patterns during the nine months, meaning that this technique can be used in laboratory routine instead of the permanent...

Abstract The genus Rhinella is one of the most diverse groups of bufonid toads, currently composed by 93 valid species and naturally distributed throughout different Neotropical ecoregions. Here, we analyze nine Brazilian populations of toads representing species of the Rhinella margaritifera and Rhinella marina groups. These new data include the first description of the R. hoogmoedi and R. proboscidae karyotypes, as well as other taxonomically unresolved forms. Chromosomal analysis of the populations revealed pronounced chromosomal uniformity (2n=22), including the diploid number and chromosomal morphology. Three different NOR-bearing chromosomes were identified: in the subterminal region of pair 10q in R. hoogmoedi, Rhinella sp. 1 and Rhinella sp. 2, in...

Autores: Faro,L.R.F.; Rodrigues,K.J.A.; Santana,M.B.; Vidal,L.; Alfonso,M.; Durán,R.
The present study was carried out in order to compare the effects of administration of organic (methylmercury, MeHg) and inorganic (mercury chloride, HgCl 2 ) forms of mercury on in vivo dopamine (DA) release from rat striatum. Experiments were performed in conscious and freely moving female adult Sprague-Dawley (230-280 g) rats using brain microdialysis coupled to HPLC with electrochemical detection. Perfusion of different concentrations of MeHg or HgCl 2 (2 µL/min for 1 h, N = 5-7/group) into the striatum produced significant increases in the levels of DA. Infusion of 40 µM, 400 µM, or 4 mM MeHg increased DA levels to 907 ± 31, 2324 ± 156, and 9032 ± 70% of basal levels, respectively. The same concentrations of HgCl 2 increased DA levels to 1240 ± 66,...

Many studies have attempted to evaluate the importance of airborne fungi in the development of invasive fungal infection, especially for immunocompromised hosts. Several kinds of instruments are available to quantitate fungal propagule levels in air. We compared the performance of the most frequently used air sampler, the Andersen sampler with six stages, with a portable one, the Reuter centrifugal sampler (RCS). A total of 84 samples were analyzed, 42 with each sampler. Twenty-eight different fungal genera were identified in samples analyzed with the Andersen instrument. In samples obtained with the RCS only seven different fungal genera were identified. The three most frequently isolated genera in samples analyzed with both devices were Penicillium,...

Comparing the artificial neural network with parcial least squares for prediction of soil organic carbon and pH at different moisture content levels using visible and near-infrared spectroscopy
Provedor de dados: 90
Autores: Tekin,Yücel; Tümsavas,Zeynal; Mouazen,Abdul Mounem.
Visible and near infrared (vis-NIR) spectroscopy is widely used to detect soil properties. The objective of this study is to evaluate the combined effect of moisture content (MC) and the modeling algorithm on prediction of soil organic carbon (SOC) and pH. Partial least squares (PLS) and the Artificial neural network (ANN) for modeling of SOC and pH at different MC levels were compared in terms of efficiency in prediction of regression. A total of 270 soil samples were used. Before spectral measurement, dry soil samples were weighed to determine the amount of water to be added by weight to achieve the specified gravimetric MC levels of 5, 10, 15, 20, and 25 %. A fiber-optic vis-NIR spectrophotometer (350-2500 nm) was used to measure spectra of soil samples...

Autores: Santos,N.A.; Simas,M.L.B.; Nogueira,R.M.T.B.L.
The aim of the present study was to measure contrast sensitivity curves for angular frequencies in the range between 2 and 96 cycles/360º in older human adult volunteers and to compare these measurements with the more usual contrast sensitivity functions for sine-wave gratings. All subjects were free of identifiable ocular disease and had normal acuity. We measured the contrast thresholds for young adults (N = 6; age range, 20-26 years) and older adults (N = 6; age range, 60-67 years) using the psychophysical forced-choice method. In this paradigm the volunteers had to choose the stimulus containing a test frequency at low contrast (e.g., either a sine-wave grating or an angular frequency stimulus), or another neutral stimulus at mean luminance (without...

ABSTRACT Intravesical botulinum toxin A (BoNTA) injection has been widely used for the treatment of detrusor overactivity in patients with neurogenic bladder due to spinal cord injury who do not respond to conventional treatment. There is no consensus about antibiotic prophylaxis for this procedure. We conducted a retrospective analysis of medical records of adult patients with spinal cord injury who underwent detrusor BoNTA injection between January of 2007 and December of 2013 in a rehabilitation hospital. Occurrence of symptomatic urinary tract infection (UTI) was assessed in 3 groups in accordance with their use of antibiotics (prophylactic dosage, 3 days, more than 3 days) for the treatment of asymptomatic bacteriuria. All patients were performing...

The extract of Ascaris suum suppresses the humoral and cellular immune responses to unrelated antigens in the mouse. In order to further characterize the suppressive components of A. suum, we produced specific monoclonal antibodies which can provide an important tool for the identification of these proteins. The A. suum immunosuppressive fractions isolated by gel filtration from an extract of adult worms were used to immunize BALB/c mice. Popliteal lymph node cells taken from the immunized animals were fused with SP2/O myeloma cells and the cloned hybrid cells obtained were screened to determine the specificity of secreted antibodies. Three monoclonal antibodies named MAIP-1, MAIP-2 and MAIP-3 were selected and were shown to react with different epitopes...

Autores: Leite,D.C.A.; Balieiro,F.C.; Pires,C.A.; Madari,B.E.; Rosado,A.S.; Coutinho,H.L.C.; Peixoto,R.S.
Many studies have evaluated the effects of biochar application on soil structure and plant growth. However, there are very few studies describing the effect of biochar on native soil microbial communities. Microbial analysis of environmental samples requires accurate and reproducible methods for the extraction of DNA from samples. Because of the variety among microbial species and the strong adsorption of the phosphate backbone of the DNA molecule to biochar, extracting and purifying high quality microbial DNA from biochar-amended soil is not a trivial process and can be considerably more difficult than the extraction of DNA from other environmental samples. The aim of this study was to compare the relative efficacies of three commercial DNA extraction...

Myelodysplastic syndrome (MDS) patients with a normal karyotype constitute a heterogeneous group from a biological standpoint and their outcome is often unpredictable. Interphase fluorescence in situ hybridization (I-FISH) studies could increase the rate of detection of abnormalities, but previous reports in the literature have been contradictory. We performed I-FISH and conventional karyotyping (G-banding) on 50 MDS patients at diagnosis, after 6 and 12 months or at any time if a transformation to acute myeloid leukemia (AML) was detected. Applying a probe-panel targeting the centromere of chromosomes 7 and 8, 5q31, 5p15.2 and 7q31, we observed one case with 5q deletion not identified by G-banding. I-FISH at 6 and 12 months confirmed the karyotype...

A new scientometric indicator, the h-index, has been recently proposed (Hirsch JE. Proc Natl Acad Sci 2005; 102: 16569-16572). The index avoids some shortcomings of the calculation of the total number of citations as a parameter to evaluate scientific performance. Although it has become known only recently, it has had widespread acceptance. A comparison of the average h-index of members of the Brazilian Academy of Sciences (BAS) and of the National Academy of Sciences of the USA (NAS-USA) was carried out for 10 different areas of science. Although, as expected, the comparison was unfavorable to the members of the BAS, the imbalance was distinct in different areas. Since these two academies represent, to a significant extent, the science of top quality...

In the present study we evaluated the precision of the ELISA method to quantify caffeine in human plasma and compared the results with those obtained by gas chromatography. A total of 58 samples were analyzed by gas chromatography using a nitrogen-phosphorus detector and routine techniques. For the ELISA test, the samples were diluted to obtain a concentration corresponding to 50% of the absorbance of the standard curve. To determine whether the proximity between the I50 of the standard curve and that of the sample would bring about a more precise result, the samples were divided into three blocks according to the criterion of difference, in modulus, of the I50 of the standard curve and of the I50 of the sample. The samples were classified into three...

Comparison of the quantitative competitive and semiquantitative RT-PCR methods for the determination of interferon-gamma mRNA levels in AIDS-free HIV-infected individuals
Provedor de dados: 56
Autores: Barabás,É.; Nagy,K.; Várkonyi,V.; Horváth,A.
IFN-gamma mRNA expression was evaluated in nonstimulated peripheral blood mononuclear cells (PBMC) of HIV-infected and seronegative individuals using quantitative competitive and semiquantitative RT-PCR and the sensitivity of these methods was compared. A significant correlation was found between quantitative competitive and semiquantitative RT-PCR in samples of both HIV-seronegative (P = 0.004) and HIV-infected individuals (P = 0.0004). PBMC from HIV-infected individuals presented a remarkable increase of IFN-gamma mRNA expression, as determined by both types of RT-PCR methods. Semiquantitative RT-PCR even without an internal standard is also acceptable for measuring cytokine mRNA expression, but less reliable if small amounts are quantified. Moreover, we...

Comparison of two slide agglutination serotyping methods and PCR-based capsule typing for the characterization of Haemophilus influenzae serotypes
Provedor de dados: 58
Autores: Silva,Maria E.N. Bonifácio da; Silva,Paulo da; Medeiros,Marta I.C.; Neme,Suzel N.; Macedo,Claudia; Marin,José Moacir.
Ninety-three nasopharyngeal Haemophilus influenzae isolates were serotyped by two slide agglutination methods (SAST 1 and SAST 2) and the results compared with those obtained by capsule type-specific PCR. SAST 1 presented a low correlation with results obtained by PCR (75.2%) while SAST 2 showed a better agreement with the molecular technique results (93.5%). These findings suggest that SAST 2 could be an alternative method for adequate detection of H.influenzae type b.

Complications of surgical treatment of cervical carcinoma
Provedor de dados: 56
A total of 302 patients with stage Ib and IIa cervical carcinoma were submitted to radical hysterectomy and lymphadenectomy during the period from 1980 to 1994. The morbidity rate was 37.5% and the mortality rate 0.6%. The most common intraoperative complications were injuries to the great pelvic vessels and the most frequent postoperative complications involved the urinary tract. The leading causes of morbidity were urinary infection (20.8%), bladder dysfunction (9.2%) and ureteral fistulas (2.9%). Although the rate of complications was high, morbidity has been decreasing over the last five years. Thus, radical hysterectomy continues to be one of the methods for the treatment of early cervical carcinoma that presents an acceptable 5-year survival rate.

Os itens que compõem a dieta das espécies são peças fundamentais na definição de sua dimensão de nicho e interferem, em última análise, em processos de estruturação das comunidades. As necessidades relacionadas à alimentação direcionam o modo pelo qual as espécies usam o ambiente. Apesar de se tratar de uma espécie com ampla distribuição geográfica, existem poucos estudos a respeito da biologia geral e do comportamento alimentar de Liophis jaegeri. Os estudos disponíveis indicam se tratar de uma espécie associada à ambientes alagados, porém, a importância de presas aquáticas na dieta desta serpente tem recebido pouca atenção. Em geral os estudos disponíveis sugerem que a presença de presas aquáticas (peixes e girinos) no trato digestivo de indivíduos...

O cultivo do coqueiro na região Centro-Oeste pode tornar-se importante opção devido à crescente demanda por água de coco e à necessidade de os produtores diversificarem as atividades e melhorarem a renda. A demanda é totalmente atendida até hoje pela oferta de frutos de outros estados, tendo sido comercializadas 1.700 t via CEASA-DF, em 1994. Apesar da importância econômica, a produtividade nacional é baixa pelo uso de genótipos não selecionados e pouca informação a respeito das práticas culturais.Com o objetivo de avaliar cultivares e híbridos de coqueiro quanto ao crescimento vegetativo, a Embrapa Cerrados-DF, em parceria com a Embrapa Tabuleiros Costeiros, desenvolve o experimento em delineamento de blocos ao acaso, com quatro e dois tratamentos,...

ABSTRACT This paper describes a case of malignant melanoma in brown coat horse, which had ataxia and proprioceptive deficits in hind limbs, progressing to permanent decubitus. The animal was euthanized and the final diagnosis was based on necropsy and histopathology. At necropsy different masses and / or nodules in skeletal muscle, bone, abdominal cavity, lungs, heart, spleen, liver, adrenal gland, lymph nodes, brain and cerebellum were found. Neurological clinical signs presented by the animal were justified by spinal cord compression caused by melanocytic mass invading the medullary canal of the flow segment of the thoracic spine (between 15th and 18th thoracic vertebrae). This is the first case report of melanoma leading to spinal cord compression in a...

Provedor de dados: 56
Autores: Vincent,M.B.; White,L.R.; Bakken,I.J.; Sjaavaag,I.
Concentration-response curves of isometric tension studies on isolated blood vessels are obtained traditionally. Although parameters such as Imax, EC50 and pA2 may be readily calculated, this method does not provide information on the temporal profile of the responses or the actual nature of the reaction curves. Computerized data acquisition systems can be used to obtain average data that represent a new source of otherwise inaccessible information, since early and late responses may be observed separately in detail

Comunidades infaunales asociadas a la almeja Ensis macha: impacto de la pesca por hidrojet
Provedor de dados: 67
Autores: Mendez,María M; Robledo,Jorgelina; Van der Molen,Silvina.
La almeja navaja (género Ensis) se explota en todo el mundo mediante una variedad de artes de pesca. Los impactos ambientales asociados a estas pesquerías incluyen cambios en las características físicas del sedimento y en la columna de agua, también efectos sobre las comunidades asociadas y sobre las mismas especies objetivo. El impacto producido depende principalmente del arte de pesca, del tipo de hábitat y de la intensidad de pesca. Los marisqueros del Golfo San José (Península Valdés, Chubut) emplean el hidrojet, una técnica que implica la inyección de agua en el sustrato para extraer navajas en distintos bancos. Si bien la explotación de este recurso en el Golfo San José aún es incipiente, resulta clave el estudio del impacto de esta pesquería para...

Autores: Coelho,Eugênio F.; Andrade Neto,Torquato M. de; Barros,Damiana L.
The Fertigation is the combined application of water and nutrients to a crop. It can be adapted to all types of agricultural crops. The objective of this study was to evaluate the effect of urea concentration in irrigation water on electrical conductivity of the soil solution and saturation extract along the first cycle of banana cv. Terra Maranhão. The experiment followed a completely randomized design with six treatments and ten replications. Treatments regarded for using three urea concentrations (1.0; 2.5 and 4.0 g L-1) in irrigation water applied by two micro irrigation systems (microsprinkler and drip). Results showed that there was a linear elevation of electrical conductivity of saturation extract and soil solution with the increase on...

Autores: Uchoa,Breno Kristoffer Beleza; Albério,Carlos Augusto Abreu; Pinto,Ana Carla Godinho; Lucena,Stefania de Medeiros Araujo; Vieira,José Luiz Fernandes.
ABSTRACT Rifampicin is used in both phases of treatment for tuberculosis. In chronic use, the short half-life and the self-induction of metabolism can decrease the levels of the drug below the minimal inhibitory concentration. The aim of the study was to investigate whether plasma concentrations of rifampicin are sustained above 0.5 µg/mL in patients with tuberculosis using 600 mg/day. Rifampicin was measured in plasma by high-performance liquid chromatography and a sputum smear microscopy was performed in all days of the study. A total of 44 male patients completed the study. On days 31, 61 and 91, the mean plasma concentrations of rifampicin were 0.6 (0.5) µg/mL, 0.55 (0.5) µg/mL and 0.46 (0.4) µg/mL. There was a high variation of rifampicin levels...

Confidencialidade e sigilo profissional em estudos sobre caça
Provedor de dados: 49
Autores: Verdade,Luciano Martins; Seixas,Cristiana Simão.
No Brasil informações sobre atividades ligadas à caça ilegal dificilmente são levantadas em função da falta de um mecanismo legal de confidencialidade e sigilo profissional que assegure ao pesquisador os princípios do direito. Sem isso, tal coleta de dados é passível de ser considerada crime ou cumplicidade criminosa, podendo o pesquisador sofrer as mesmas penalidades legais que os próprios caçadores. Este procedimento é questionável do ponto de vista filosófico, legal e técnico. A sustentabilidade biológica da caça, legal ou ilegal, só poderá ser avaliada por meio de pesquisas sobre o tema, envolvendo coleta de dados. A fim de mudar tal cenário, é necessário que biólogos tenham o direito ao sigilo profissional e à confidencialidade em pesquisas sobre a...

Autores: Cardoso,Márcio Zikán; Brito,Marcos Roberto; Lion,Marília Bruzzi.
Abstract Heliconius nattereri C. Felder &amp; R. Felder, 1865 is an enigmatic and rarely collected species. Because of severe habitat reduction, the species is currently listed as endangered. We here report the confirmation of a northernmost population. This collection and further observations reported here add two more known localites to the distribution of the species. Two of the three confirmed locations are in protected areas. We worry that the northern population may be at great risk because it is not formally protected. We urge conservation efforts to preserve the local forests where the species is found.

Autores: Silva,S.M.M.S; Ferreira,L.H; Souza,F.A.L; Nascimento,E.F; Costa,E.A; Paixão,T.A; Santos,R.L.
Conidiobolomycosis is an infection caused by fungi of the genus Conidiobolus spp. that is associated with a granulomatous rhinitis in humans and animals. In sheep, the disease is clinically characterized by respiratory changes, exophthalmia, craniofacial asymmetry, and fever. Microscopically, there are multifocal granulomas containing intralesional hyphae. For a long time, this disease was diagnosed as Enzootic Ethmoid Tumor. This report described three cases of conidiobolomycosis that had been previously diagnosed as Enzootic Ethmoid Tumor. Samples of nasal cavity, lung, parotid gland, and lymph node from three sheep submitted to histopathological examination in 1979 were retrieved in 2010 for a new histological, histochemical, and immunohistochemical...

Connections: can the 20th century coronary heart disease epidemic reveal something about the 1918 influenza lethality?
Provedor de dados: 56
Autores: Azambuja,M.I.
This essay proposes that the ecologic association shown between the 20th century coronary heart disease epidemic and the 1918 influenza pandemic could shed light on the mechanism associated with the high lethality of the latter. It suggests that an autoimmune interference at the apoB-LDL interface could explain both hypercholesterolemia and inflammation (through interference with the cellular metabolism of arachidonic acid). Autoimmune inflammation, then, would explain the 1950s-60s acute coronary events (coronary thrombosis upon influenza re-infection) and the respiratory failure seen among young adults in 1918. This hypothesis also argues that the lethality of the 1918 pandemic may have not depended so much on the 1918 virus as on an immune vulnerability...

Connexin domains relevant to the chemical gating of gap junction channels
Provedor de dados: 56
Most cells exchange ions and small metabolites via gap junction channels. These channels are made of two hemichannels (connexons), each formed by the radial arrangement of six connexin (Cx) proteins. Connexins span the bilayer four times (M1-M4) and have both amino- and carboxy-termini (NT, CT) at the cytoplasmic side of the membrane, forming two extracellular loops (E1, E2) and one inner (IL) loop. The channels are regulated by gates that close with cytosolic acidification (e.g., CO2 treatment) or increased calcium concentration, possibly via calmodulin activation. Although gap junction regulation is still unclear, connexin domains involved in gating are being defined. We have recently focused on the CO2 gating sensitivity of Cx32, Cx38 and various...

Conservação dos recursos hídricos em brejos de altitude: o caso de Brejo dos Cavalos, Caruaru, PE
Provedor de dados: 91
Autores: Braga,Ricardo A. P.; Cabral,Jaime J.S.P.; Montenegro,Suzana M.G.L.; Perrier Júnior,Geraldo S.
Brejos de altitude são formações vegetais disjuntas da Mata Atlântica, que ocorrem no Agreste de Pernambuco e Paraíba, como ilhas de umidade no ambiente semi-árido da Caatinga. O Parque Vasconcelos Sobrinho, situado na Serra dos Cavalos, em Caruaru, PE, é um exemplo do pouco que resta desses brejos na região. Com 359 ha, abriga uma floresta exuberante e diversos corpos d'água, porém vem sofrendo intenso processo de degradação, em decorrência da agricultura irrigada em seu interior e da exploração de argila no entorno. Para uma caracterização dos recursos hídricos foram obtidos, no período de 1998 a 2000, dados de chuva, de vazão nos riachos do Chuchu e Capoeirão, e de qualidade da água, nos dois cursos d'água e nos três maiores reservatórios existentes no...

Considerations regarding the dominance of Cylindrospermopsis raciborskii under low light availability in a low phosphorus lake
Provedor de dados: 39
Autores: Tonetta,Denise; Hennemann,Mariana Coutinho; Brentano,Débora Monteiro; Petrucio,Mauricio Mello.
ABSTRACTAlthough many studies have shown that the dispersion, increased abundance and dominance of cyanobacteria can be attributed to nutrient enrichment, we discuss features contributing to the dominance of Cylindrospermopsis raciborskii in a shallow, polymictic, subtropical coastal lake with low phosphorus and light limitation (Peri Lake). The presence and dominance of C. raciborskii in an environment with such characteristics emphasizes the idea that nutrients alone do not explain the high density of this cyanobacterium. Other features should be considered in explaining this species dominance, such as phosphorus storage and physiological flexibilitywhich seem to be key features to high densities in low phosphorus systems.

RESUMO A vacinação é a forma mais utilizada para prevenir a bronquite infecciosa causada pelo vírus da bronquite infecciosa das galinhas (IBV). Contudo, as vacinas convencionais são incapazes de diferenciar aves infectadas de vacinadas. No presente trabalho foi construído, caracterizado, e avaliado como candidato vacinal, um adenovírus recombinante expressando o gene N do IBV. O gene N foi clonado em um adenovírus humano tipo 5 defectivo e transfectado para as células HEK-293A para gerar rAd5_N. Após o vetor ser obtido como esperado e a confirmação da expressão da proteína N em HEK-293ª, foi realizada inoculação pela via oculo-nasal na dose de 10  7 TCID  50 /0,1mL para imunização de galinhas livres de patógenos específicos (SPF).

Control del arrastre de sedimentos post-incendio: efectividad de fajinas en un bosque seco montañoso (Salta, Argentina)
Provedor de dados: 67
Autores: Tálamo,Andrés; Arévalo,Eliana V; Martínez Gálvez,Fernanda M; Harmann,Salomé C; Díaz Leguizamón,Marina A; Croce,Joanna.
Los incendios forestales en bosques montañosos pueden modificar las tasas de infiltración y de escorrentía, lo cual aumenta el arrastre de sedimentos ladera abajo. Por lo tanto, es urgente diseñar e implementar técnicas de control de sedimentos en laderas incendiadas. Una metodología sencilla y económica es la construcción de fajinas (i.e., una empalizada de forma cilíndrica construida con ramas trenzadas). Nuestro objetivo fue evaluar la efectividad de colocar distintos números de fajinas (0, 2 y 3) en distintas posiciones de la ladera para controlar el arrastre de sedimentos en una ladera quemada (Serranía de Tres Cerritos, Salta- Argentina). Encontramos que a mayor número de fajinas, y ubicándolas en las partes bajas e intermedias de la ladera, el...

Control of the phosphorylation of the astrocyte marker glial fibrillary acidic protein (GFAP) in the immature rat hippocampus by glutamate and calcium ions: possible key factor in astrocytic plasticity
Provedor de dados: 56
The present review describes recent research on the regulation by glutamate and Ca2+ of the phosphorylation state of the intermediate filament protein of the astrocytic cytoskeleton, glial fibrillary acidic protein (GFAP), in immature hippocampal slices. The results of this research are discussed against a background of modern knowledge of the functional importance of astrocytes in the brain and of the structure and dynamic properties of intermediate filament proteins. Astrocytes are now recognized as partners with neurons in many aspects of brain function with important roles in neural plasticity. Site-specific phosphorylation of intermediate filament proteins, including GFAP, has been shown to regulate the dynamic equilibrium between the polymerized and...

The objective of the present study was to evaluate the risk factors associated with the presence of coronary artery calcification (CAC) in patients with type 1 diabetes (T1D). A cross-sectional study was conducted on 100 consecutive T1D patients without coronary artery disease, with at least 5 years of diabetes and absence of end-stage renal disease. Mean age was 38 ± 10 years and 57% were males. CAC score was measured by multidetector computed tomography (Siemens Sensation 64 Cardiac). The insulin resistance index was measured using the estimated glucose disposal rate (eGDR). The eGDR was lower among CAC-positive patients than among CAC-negative patients, suggesting an increased insulin resistance. In a logistic regression model adjusted for age (at...

The objective of this work was to compare the values of milk somatic cell counts (SCC) using the Somacount 300, and two detergents for sample preparation. The equipment was calibrated using the detergent RBS 35. Forty independent milk samples were analyzed. Each sample was randomly divided into two subsamples, and each subsample was analyzed after preparation with either RBS 35 or Extram MA 01 Alkaline detergents. The correlation coefficient between the two methods was high (0.998). This finding suggests the possibility of substitution of RBS 35 for an economical alternative.

RESUMO A presente comunicação objetivou avaliar a quantificação do caseínomacropeptídeo (CMP), bem como diferenciá-lo (devido à adulteração com soro) do pseudo-CMP (devido à proteólise bacteriana) em amostras de leite cru coletadas nos domicílios do sul do Brasil. Os resultados reforçam a necessidade de práticas higiênicas durante a ordenha e estocagem do leite. As amostras de leite estudadas não estavam adulteradas por adição de soro, mostrando que a análise por cromatografia de exclusão por tamanho deve ser complementada a fim de revelar a identidade do peptídeo (CMP ou pseudo-CMP). A contagem bacteriana total (TBC) também se mostrou útil como indicador da contaminação do leite por micro-organismos proteolíticos, uma vez que uma relação diretamente...

The aim of this study was to determine how different types of P. vivax affect clinical symptoms and parasitaemia clearance. Blood was collected from individuals from Pará State, Brazil. The patients were treated as chloroquine plus primaquine. P. vivax were typed daily till D7 and again on D30. Now we can confirm a previously reported correlation between P. vivax genotype and response to chloroquine. Clinical symptoms do not allow for objective identification of different P. vivax types in the Brazilian Amazon, since the VK247 and P. vivax-like have only been detected in mixed infections.

ABSTRACT This study aimed to assess the prevalence and influence of urinary tract infection on the reproductive performance of sows. The animals underwent urine tests using reagent strips and diagnosed as positive or negative. They were then divided into two groups of 30 positive and 30 negative sows for urinary tract infection. Each sow was considered an experimental unit and was followed from labor to weaning. The animals were assessed for their reproductive performance (labor duration, number of live births, mummified piglets, and stillbirths, and postpartum diseases). After weaning, the weaning-estrus interval and rate of return to estrus were assessed. A thermographic camera was used to identify hyperthermia of the mammary system and its relation with...

ABSTRACT Rahnella aquatilis is an environmental Gram-negative bacillus that is rarely reported as human pathogen, being mainly associated with infections in immunocompromised patients. Herein we describe two cases ofR. aquatilis isolates recovered from endotracheal aspirate cultures of different patients in a tertiary hospital located in the city of São Paulo, Brazil. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rDNA gene sequencing were performed to confirm bacterial identification after the isolates being erroneously identified as Pantoea spp. by automated system. Both isolates showed the same PFGE pattern and presented the ß-lactamase encoding geneblaRAHN-1, responsible for resistance to cephalothin. The isolates...

Coupling of palmitate to ovalbumin inhibits the induction of oral tolerance
Provedor de dados: 56
Autores: Oliveira,F.M.; Silva-Neto,A.F.; Silva,C.A.; Gontijo,C.M.
Oral tolerance is a phenomenon that may occur in animals exposed to protein antigens for the first time by the oral route. They become unable to produce immune responses at the levels normally observed when they are immunized parenterally with antigen in the presence of adjuvants. Lipids have been used as adjuvants for both parenteral and oral immunization. In the present study we coupled ovalbumin with palmitate residues by incubating the protein with the N-hydroxysuccinimide palmitate ester and tested the preparation for its ability to induce oral tolerance. This was performed by giving 20 mg of antigen to mice by the oral route 7 days prior to parenteral immunization in the presence of Al(OH)3. Mice were bled one week after receiving a booster that was...

Cover plants are essential for the sustainability of no-tillage systems in tropical regions. However, information on the effects of these plants and N fertilization on soil organic matter fractions is still scarce. This study evaluated the effect of cover crops with different chemical composition and of N topdressing on the labile and humified organic matter fractions of an Oxisol of the Cerrado (savanna-like vegetation). The study in a randomized complete block design was arranged in split-plots with three replications. Four cover species were tested in the plots and the presence or absence of N topdressing in the subplot. The following cover species were planted in succession to corn for eight years: Urochloa ruziziensis; Canavalia brasiliensis M. ex...

Creatinina en sangre: calidad analítica e influencia en la estimación del Índice de Filtrado Glomerular
Provedor de dados: 38
Autores: Perazzi,Beatriz; Angerosa,Margarita.
La medición real del Índice de Filtrado Glomerular (IFG) es aceptada como el mejor método para evaluar la función renal. Diversas organizaciones y sociedades científicas nacionales e internacionales recomiendan el uso de ecuaciones que estiman el IFG a partir del valor sérico de creatinina, para facilitar la detección, evaluación y manejo de la Enfermedad Renal Crónica (ERC). La política establecida por el National Kidney Disease Education Program (NKDEP) es la de estimar el IFG en base a la ecuación Modification Diet Renal Disease (MDRD). En esta ecuación, el único parámetro medido es la creatinina sérica. Es importante ajustar la metodología de la creatinina dado que el sesgo producido en valores que están dentro del rango 0,95 - 1,7 mg/dL,...

Crotoxin, the major toxin from the rattlesnake Crotalus durissus terrificus, inhibits ³H-choline uptake in guinea pig ileum
Provedor de dados: 56
Autores: Kattah,L.S.; Santoro,M.M.; Diniz,C.R.; De Lima,M.E.
We examined the effect of crotoxin, the neurotoxic complex from the venom of the South American rattlesnake Crotalus durissus terrificus, on the uptake of ³H-choline in minces of smooth muscle myenteric plexus from guinea pig ileum. In the concentration range used (0.03-1 µM) and up to 10 min of treatment, crotoxin decreased ³H-choline uptake by 50-75% compared to control. This inhibition was time dependent and did not seem to be associated with the disruption of the neuronal membrane, because at least for the first 20 min of tissue exposure to the toxin (up to 1 µM) the levels of lactate dehydrogenase (LDH) released into the supernatant were similar to those of controls. Higher concentrations of crotoxin or more extensive incubation times with this toxin...

Soros de aves experimentalmente infectadas, contendo espiroquetas viáveis, foram submetidos a dois procedimentos antes da criopreservação: glicerol na diluição de 1/2 (v/v), designado como soro com glicerol a 50% (GS), e dimetilsulfóxido na proporção de 1/10 (v/v), designado como soro com DMSO a 10% (DS). Após 15 meses de estocagem em nitrogênio líquido, amostras dos tratamentos GS e DS foram descongeladas e suas infectividades foram testadas em frangos susceptíveis. Apesar de ambos os procedimentos terem mantidos a infectividade da bactéria, DMSO a 10% no soro de frango apresentou-se mais satisfatório como criopreservante.

Provedor de dados: 102
Autores: Blum,Luiz E. B.; Amarante,Cassandro V. T.; Valdebenito-Sanhueza,Rosa M.; Guimarães,Letícia S.; Dezanet,Alexandre; Hack Neto,Pedro.
As podridões pós-colheita podem ocasionar perdas substanciais em maçãs (Malus domestica). O mofo azul (Penicillium expansum), a podridão amarga (Glomerella cingulata) e a podridão olho-de-boi (Pezicula malicorticis) estão entre as mais comuns. Grande atenção tem sido dada ao uso de alternativas de controle às doenças pós-colheita. A aplicação pós-colheita de leveduras, como o Cryptococcus laurentii, é uma das opções. Neste estudo testou-se a eficiência de C. laurentii (isolado 36) para o controle de podridões em maçãs 'Fuji' e 'Gala'. Após aplicação dos produtos, através de imersão, os frutos foram armazenados em laboratório (15-20 ºC / 60-70% UR) ou em câmara fria (1 ºC / 90-95% UR). Os patógenos foram inoculados na concentração de 10² conídios ml-1, a...

Current aspects of antibiotic prophylaxis for upper gastrointestinal bleeding in cirrhosis patients
Provedor de dados: 55
Autores: Almeida,Delvone; Paraná,Raymundo.
Bacterial infection is a common complication in cirrhotic patients. The portal hypertension as well as the immune depression observed in these patients can explain this high incidence of bacterial infection. Because of the high probability of cirrhotic patients to develop infections, antibiotic prophylaxis is warranted in some conditions, such as upper gastrointestinal bleeding or after spontaneous bacterial peritonitis. Nevertheless, antibiotic prophylaxis is not widely recommended for cirrhotic patients.

ABSTRACT Biosynthesized from very long-chain fatty acid wax precursors, n-alkanes make a valuable contribution to the taxonomy of plants. The alkane components of foliar epicuticles of seven Neotropical species of Lecythidaceae were investigated: Bertholletia excelsa, Cariniana legalis, Couroupita guianensis, Eschweilera alvimii, Eschweilera ovata, Gustavia augusta and Lecythis pisonis. Specimens were collected in the metropolitan area of Recife, Pernambuco, and their n-alkane fractions were analyzed by gas chromatography. The chemical relationships among the species were then evaluated using cophenetic correlation and UPGMA. Among the seven species, a total of 15 n-alkanes, with 21-35 carbon atoms, were identified and formed a consistent group of B....

Cyclosporin A preferentially attenuates skeletal slow-twitch muscle regeneration
Provedor de dados: 56
Autores: Miyabara,E.H.; Aoki,M.S.; Moriscot,A.S.
Calcineurin, a Ca2+/calmodulin-dependent phosphatase, is associated with muscle regeneration via NFATc1/GATA2-dependent pathways. However, it is not clear whether calcineurin preferentially affects the regeneration of slow- or fast-twitch muscles. We investigated the effect of a calcineurin inhibitor, cyclosporin A (CsA), on the morphology and fiber diameter of regenerating slow- and fast-twitch muscles. Adult Wistar rats (259.5 ± 9 g) maintained under standard conditions were treated with CsA (20 mg/kg body weight, ip) for 5 days, submitted to cryolesion of soleus and tibialis anterior (TA) muscles on the 6th day, and then treated with CsA for an additional 21 days. The muscles were removed, weighed, frozen, and stored in liquid nitrogen. Cryolesion did...

Cyclosporin inhibits hyperalgesia and edema in arthritic rats: role of the central nervous system
Provedor de dados: 56
Since arthritis induced by Mycobacterium products (adjuvant) in rats is considered to be immunologically driven, the objective of the present study was to determine if the immunosuppressor drug cyclosporin could affect hindpaw edema and joint hyperalgesia simultaneously. Female Holtzman rats (140-170 g) presented hyperalgesia and edema on the 8th and 12th day following adjuvant injection. Daily systemic (oral or intramuscular) administration of cyclosporin (0.5-5.0 mg kg-1 day-1) or dexamethasone (0.01-0.1 mg kg-1 day-1) for 15 days starting on day zero dose-dependently inhibited the hindpaw edema and hyperalgesia in arthritic rats. However, hyperalgesia but not edema could be detected two days after cyclosporin withdrawal. We concluded that a) the...

Autores: Ribeiro,H.F.; Alcântara,D.F.A.; Matos,L.A.; Sousa,J.M.C.; Leal,M.F.; Smith,M.A.C.; Burbano,R.R.; Bahia,M.O.
Gastric cancer is the fourth most frequent type of cancer and the second cause of cancer mortality worldwide. The genetic alterations described so far for gastric carcinomas include amplifications and mutations of the c-ERBB2, KRAS, MET, TP53, and c-MYC genes. Chromosomal instability described for gastric cancer includes gains and losses of whole chromosomes or parts of them and these events might lead to oncogene overexpression, showing the need for a better understanding of the cytogenetic aspects of this neoplasia. Very few gastric carcinoma cell lines have been isolated. The establishment and characterization of the biological properties of gastric cancer cell lines is a powerful tool to gather information about the evolution of this malignancy, and...

Autores: Burbano,R.R.; Lima,E.M.; Khayat,A.S.; Barbieri Neto,J.; Cabral,I.R.; Bastos Jr.,L.; Bahia,M.O.; Casartelli,C.
Twelve breast fibroadenomas were analyzed cytogenetically and only four were found to have clonal alterations. The presence of chromosomal alterations in fibroadenomas must be the consequence of the proliferating process and must not be related to the etiology of this type of lesion. In contrast, the few fibroadenomas that exhibit chromosomal alterations are likely to be those presenting a risk of neoplastic transformation. Clonal numerical alterations involved chromosomes 8, 18, 19, and 21. Of the chromosomal alterations found in the present study, only monosomy of chromosomes 19 and 21 has been reported in breast fibroadenomas. The loss of chromosome 21 was the most frequent alteration found in our sample. The study of benign proliferations and their...

Cytotoxic activity of BCG-activated macrophages against L929 tumor cells is nitric oxide-dependent
Provedor de dados: 56
Autores: Nascimento,F.R.F.; Ribeiro-Dias,F.; Russo,M.
The tumoricidal activity of activated macrophages has been attributed largely to the release of tumor necrosis factor (TNF), or to the production of reactive oxygen or nitrogen intermediates. The L929 tumor cell line (a murine fibroblast-like cell) when treated with actinomycin D (ActD) has been used to measure TNF&lt;FONT FACE="Symbol"&gt;a&lt;/FONT&gt; cytotoxicity. In the present study, we determined the cytotoxic activity of BCG-activated peritoneal macrophages against ActD-untreated L929 tumor cells. Furthermore, we measured the production of hydrogen peroxide (H2O2), nitric oxide (NO) and TNF by macrophages cultured in the presence or absence of L929 cells. As expected, BCG-activated macrophages produced significant amounts of H2O2 (16.0 ± 3.0 µM),...

The cytotoxic activity of amino (3a-e), aza-1-antraquinone (4a-e) lapachol derivatives against Ehrlich carcinoma and human K562 leukemia cells was investigated. Cell viability was determined using MTT assay, after 48 (Ehrlich) or 96 h (K562) of culture, and vincristine (for K562 leukemia) and quercetin (for Ehrlich carcinoma) were used as positive controls. The results showed dose-dependent growth-inhibiting activities and that the amino derivatives were active against the assayed cells, whereas the 4a-e derivatives were not. The allylamine derivative 3a was the most active against Ehrlich carcinoma, with IC50 = 16.94 ± 1.25 µM, and against K562 leukemia, with IC50 = 14.11 ± 1.39 µM.

Abstract Culture supernatant of sepsis-associated Escherichia coli (SEPEC) isolated from patients with sepsis caused loss of intercellular junctions and elongation of human umbilical vein endothelial cells (HUVEC). The cytotoxic factor was purified from culture supernatant of SEPEC 15 (serogroup O153) by liquid chromatography process. PAGE (polyacrylamide gel electrophoresis) showed that the purified SEPEC cytotoxic factor had a molecular mass of ∼150 kDa and consisted of at least two subunits. At the concentration of 1 CD50 (40 μg/mL) did facilitate transcytosis through the HUVEC cells monolayer of SEPEC 15 as much as E. coli K12 within 30 min without affecting cell viability. These results suggest that this cytotoxic factor, named as SPF (SEPEC's...

Dangerous neighborhood: saurophagy between syntopic Tropidurus lizards
Provedor de dados: 49
Autores: Passos,Daniel Cunha; Monteiro,Felipe Augusto Correia; Nogueira,Carlos Henrique de Oliveira.
Saurophagy constitutes an important source of mortality among lizards and has been reported for the genus Tropidurus. However, the extension of this behavior remains unknown. Herein, we record the predation of T. jaguaribanus by its congener T. hispidus. This is the first report of saurophagy among different species of syntopicTropidurus. Furthermore, whereas published records of saurophagy tend to be directed against juveniles, this case involved two adult individuals.

Dangerous snakes, deadly snakes and medically important snakes
Provedor de dados: 80
Autores: Silva,Anjana.
This correspondence argues that the dangerousness of a venomous snake species is not solely determined by the venom characteristics or the lethality of the snake, and recognizes that medical importance comprises a key variable as well. The medical importance of a snake is determined by several factors - including frequency of medical attention after a bite, local or systemic envenomation provoked by the bite, fatal bites, long term consequences, availability of antivenom therapy as well as the size of the population at risk - that may vary from one region to another.

ABSTRACT  Introduction: This study aimed to characterize Staphylococcus aureus isolates from bloodstream infections in patients attending a teaching hospital, between 2011 and 2015.  Methods: The minimum inhibitory concentration for daptomycin, linezolid, oxacillin, teicoplanin, vancomycin, and trimethoprim/sulfamethoxazole was accessed by broth microdilution. SCCmec type and clonal profile were determined by molecular tests. Vancomycin heteroresistance was evaluated using screening tests and by population analysis profile/area under the curve.  Results: Among 200 S. aureus isolates, 55 (27.5%) were MRSA, carrying SCCmec II (45.5%) or IV (54.5%). The most frequent MRSA lineages were USA100 (ST5-II) (45.5%) and USA800 (ST5-IV) (30.9%). Six isolates were...

Decomposição da fitomassa de plantas de cobertura e liberação de nitrogênio em função da quantidade de resíduos aportada ao solo sob sistema plantio direto
Provedor de dados: 65
Autores: Acosta,José Alan de Almeida; Amado,Telmo Jorge Carneiro; Silva,Leandro Souza da; Santi,Anderson; Weber,Mirla Andrade.
O sucesso do sistema plantio direto (SPD) está alicerçado na rotação de culturas, que proporciona elevada adição de diferentes tipos de resíduos culturais ao solo. Entretanto, cada resíduo cultural tem uma cinética específica de decomposição, o que é determinante na mineralização e imobilização líquida de nitrogênio (N) no solo. Este trabalho teve como objetivo avaliar a taxa de decomposição e a liberação de N de plantas de cobertura de inverno, quando diferentes quantidades de fitomassa da parte aérea foram aportadas à superfície do solo. O experimento foi conduzido em Argissolo arênico na área do Departamento de Solos da Universidade Federal de Santa Maria (UFSM), com delineamento experimental de blocos ao acaso, com três repetições, durante as safras de...

We studied the effect of complete spinal cord transection (SCT) on gastric emptying (GE) and on gastrointestinal (GI) and intestinal transits of liquid in awake rats using the phenol red method. Male Wistar rats (N = 65) weighing 180-200 g were fasted for 24 h and complete SCT was performed between C7 and T1 vertebrae after a careful midline dorsal incision. GE and GI and intestinal transits were measured 15 min, 6 h or 24 h after recovery from anesthesia. A test meal (0.5 mg/ml phenol red in 5% glucose solution) was administered intragastrically (1.5 ml) and the animals were sacrificed by an iv thiopental overdose 10 min later to evaluate GE and GI transit. For intestinal transit measurements, 1 ml of the test meal was administered into the proximal...

Reported neuroimaging studies have shown functional and morphological changes of temporal lobe structures in panic patients, but only one used a volumetric method. The aim of the present study was to determine the volume of temporal lobe structures in patients with panic disorder, measured by magnetic resonance imaging. Eleven panic patients and eleven controls matched for age, sex, handedness, socioeconomic status and years of education participated in the study. The mean volume of the left temporal lobe of panic patients was 9% smaller than that of controls (t21 = 2.37, P = 0.028). In addition, there was a trend (P values between 0.05 and 0.10) to smaller volumes of the right temporal lobe (7%, t21 = 1.99, P = 0.06), right amygdala (8%, t21 = 1.83, P =...

Elephantgrass shows a high stocking rate only during the rainy season. Forage production is drastically reduced in the dry season. One of the alternatives to minimize this problem is the supplementation with sugarcane plus urea. In this trial the main goal was to estimate the dry matter intake (DMI) of elephantgrass, chopped sugarcane plus 1% urea and their degradability in three lactating (11.6kg/milk/day) rumen fistulated crossbred cows (472kg/L.W.) grazing elephantgrass during the dry season. The cows had access during three consecutive night to the paddocks grazed every 30 days in a stocking rate, of 4.5 cows/hectare. Between the two milking times, cows received chopped sugarcane plus 1% urea. The DMI was on average 1.01%/L.W. for the elephantgrass and...

Delay in gallbladder emptying during the perimenopausal period
Provedor de dados: 56
Autores: Petroianu,A.; Oliveira,L.C.; Vieira,M.I.
A pilot study has ascribed an important role in gallbladder motility and emptying to the perimenopausal period. To assess the effect of this period on gallbladder emptying and cholelithogenesis, 25 women in the perimenopausal period without gallbladder disease were submitted to cholangiography and two ultrasound exams. The time for gallbladder emptying and the presence of cholelithiasis were assessed. All patients presented a delay in gallbladder emptying with no relationship to the pre- or postmenopausal period. This finding was not related to lithogenesis. Gallbladder emptying time is longer during the perimenopausal period.

Demographic response to the manipulation of adult females in corn mouse populations
Provedor de dados: 67
Autores: Gómez,María D; Steinmann,Andrea R; Priotto,José W.
Variation in population abundance is a consequence of changes in demographic parameters such as survival and recruitment. These demographic parameters can be affected by intraspecific competition, thus adults may play an important role infl uencing the survival and/or reproduction of juvenile individuals in many species of small mammals. We present an analysis of Calomys musculinus populations using capturemark- recapture models in order to evaluate the effect of female removal on their demography. The study was carried out in four enclosures during two different periods: a reference period and a treatment period, with the removal of adult females. Reference period was analyzed to describe population demography without manipulations. In treatment period,...

Autores: Periago,María E; Leynaud,Gerardo C.
The fecal pellet group count technique was used to estimate gray brocket deer density in a protected area in the west of Córdoba province (Chancaní Reserve), Argentina. Seventy plots were surveyed for brocket pellets on two occasions: summer (February) and winter (August). The density of brockets recorded were 4.41 individuals/km² in summer and 5.12 individuals/km² in winter. It was the first count of the species density in the Reserve and constitutes an important management tool for monitoring the population of this species within this protected area, as well as in other similar habitats in the arid Chaco.

Abstract Ocelots play a key role in ecological communities as mesopredators affecting the lower trophic level and other mesopredators. They show great variability in ecological traits across their distribution, but knowledge of this species is missing in several regions where it occurs. Here, we present the first study of ocelot in the Brazilian semiarid of Caatinga. Arid habitats might keep carnivore population density low and therefore vulnerable to environmental shocks and to human-induced changes, at risk of local extinction. To assess their population status, we used camera traps between September 2009 and January 2010. We estimated the density of ocelots using a spatially explicit capture-recapture method (SECR) to be 3.16 ± 0.46 individuals per 100...

Depressive symptoms and C-reactive protein in a Brazilian urban community
Provedor de dados: 56
Autores: Dressler,W.W.; Balieiro,M.C.; Ribeiro,R.P.; Dos-Santos,J.E.
Psychological depression is an independent risk factor for coronary artery disease. C-reactive protein has been implicated as a mediator of the effect of psychological depression. Several studies have found that individuals, especially men, who report higher levels of psychological depression also have higher levels of C-reactive protein. The current study was undertaken to replicate these results in a Brazilian population, in which there is a much wider range of variation in both background characteristics (such as socioeconomic status) and coronary artery disease risk factors. A sample of 271 individuals was interviewed using the Center for Epidemiological Studies Depression Scale. Fasting blood samples were obtained and evaluated for C-reactive protein...

Provedor de dados: 56
Autores: Chiossi,M.P.V.; Costa,R.S.; Roselino,A.M.F.
Pemphigus foliaceus (PF) is an autoimmune bullous disease endemic in Brazil. Since serum IL-12 is increased in patients with PF and Langerhans cells (LC) produce IL-12, we titrated serum autoantibodies by indirect immunofluorescence, and quantified epidermal dendritic cells, known as LC, and dermal dendritic cells (DC). Biopsies of blistering lesions were obtained from 22 patients, 13 of whom were submitted to biopsy of both injured and of apparently healthy skin. The control groups consisted of skin from 8 cadavers and from 12 women submitted to breast plastic surgery. LC and DC were identified with anti-CD1a antibody and quantified by morphometric analysis. LC number in the lesion and in apparently healthy skin from PF patients was similar to that of...

El conocimiento sobre la reproducción del Burrito Negruzco (Porzana spiloptera) es escaso. En este trabajo se describe el pichón de esta especie, detallándose el patrón de coloración del pico, que es diagnóstico en Rallidae. Se compara este carácter con el de otras especies de burritos pequeños, en particular con Laterallus jamaicensis, que posee vocalizaciones muy similares. Se descarta la posibilidad de que un espécimen de pichón de Rallidae sin asignación de especie depositado en el Museo Argentino de Ciencias Naturales "Bernardino Rivadavia" corresponda a Porzana spiloptera.

Provedor de dados: 45
Autores: Bastos,P.; Reis,I.M.M. dos; Costa,R.L.; Ferreira,J.F.
ABSTRACT The octopus Octopus cf. vulgaris is a potential species to diversify aquaculture. Due to absence of balanced commercial diet, growth of the O. cf. vulgaris is based on natural diet with local and low-cost inputs. In Brazil, studies on experimental octopus ongrowing are recent and there is little available data. We evaluated the performance, survival and food consumption of O. vulgaris fed on mussel Perna perna   for 20 days. Six octopuses with initial weight of 415±12.73g (mean±standard deviation) were divided into two groups (n=3 octopuses/group) according to the diet: MC Group (frozen mussels) and MV Group (live mussels). The Weight Gain of octopuses was 273.33±94.52g and 340.00±26.46g; the Absolute Growth Rate was 13.67±4.73 and...

Desenvolvimento de marcadores moleculares para análogos a genes de resistência em Arachis spp. silvestres
Provedor de dados: 102
Autores: Guimarães,Patrícia M.; José,Ana Carolina F.V.; Proite,Karina; Bertioli,David J.; Leal-Bertioli,Soraya C. M.
O maior grupo de genes de resistência de plantas já clonados codifica para proteínas com um sítio de ligação a nucleotídios (NBS) na região N-terminal, e um domínio rico em repetições de leucina (LRR) na região C-terminal. Genes desta classe conferem resistência a diversos patógenos incluindo vírus, bactérias, fungos e nematóides. Para diferentes espécies do gênero Arachis, primers de "polymerase chain reaction" (PCR) degenerados foram construídos para a região NBS, e o produto de tradução putativo indicou similaridade com proteínas de resistência conhecidas sendo denominados análogos a genes de resistência (RGAs). Doze destes RGAs foram utilizados para o desenvolvimento de marcadores moleculares baseados em seus padrões de hibridização com DNA de Arachis...

Desinserção proximal do músculo sartório na correção da luxação patelar medial graus III e IV, em cães
Provedor de dados: 45
Autores: Tudury,E.A; Figueiredo,M.L; Kemper,B; Araújo,F.P; Chioratto,R; Marques,N.B; Fernandes,T.H.T.
Six surgical corrections were performed with techniques of bone and soft tissue reconstruction, according to the individual presentation of each patient, in four Toy breed dogs, which had grades III and IV luxation, two of them bilaterally operated. During the recovery excessive medial tension associated to the Sartorius muscle was detected, which motivated its release at the iliac insertion. The animals had a functional recovery of the limb after 15 days, and complications or loss of function related to the release of the Sartorius muscle were not observed even after six months. It is believed that the proximal disinsertion of this muscle can be necessary and effective in some patients as a complementary technique to release medial tension in dogs with...

This paper reports the detection of bovine herpesvirus type 5 (BoHV-5) by a specific nested PCR assay. Samples were collected from the central nervous system (CNS) of cattle from Minas Gerais and São Paulo States, Brazil. All animals died presenting neurological symptoms. Nineteen frozen CNS samples analyzed had been previously tested by fluorescence antibody test for rabies virus and showed negative results. Three paraffin-embedded brain tissue samples were examined by histopatology and the observed alterations suggested nonsuppurative meningoencephalitis. BoHV-5 was detected in five (22.7%) among 22 tested samples. The occurrence of BoHV-5 infection is reported in the Southeast region of Brazil, indicating that epidemiological studies should be carried...

Apoptosis is a well-known specific process of cell death that normally occurs in physiological situations such as tissue or organ development and involution. During tumor growth there is a balance between proliferation and cell death which involves apoptotic mechanisms. In the present study genomic DNAs from 120 breast tumor biopsies were analyzed by agarose gel electrophoresis and none of them presented the fragmentation pattern characteristic of the apoptosis process. However, 33% of the 105 breast cancer patients clearly showed the apoptotic pattern when DNA from blood cells was analyzed. None of the DNAs from healthy volunteer blood cells showed any trace of apoptosis. Since the breast cancer patients were not receiving chemo- or hormone therapy, the...

ABSTRACT This work performed a phenotypic and genotypic characterization of 79 clinical isolates of Enterobacteriaceae and Pseudomonadaceae collected in hospitals of Southern Ecuadorin 2013. Our results showed a high incidence of β-lactamases and ESBLs with blaTEM and blaCTX-M as the prevalent genes, respectively. By direct sequencing of PCR amplicons, the different β-lactamases and variants of the genes were also distinguished. Our results revealed a predominance of TEM-1 β-lactamase and the presence of different CTX-M variants with a prevalence of CTX-M-15. Two infrequent CTX-M variants in South America were also identified. To the best of our knowledge, this is one of the first studies describing the genetic characteristics of β-lactamases in Ecuador.

Provedor de dados: 102
Autores: Carmona,Marcelo A.; Zweegman,Juan; Reis,Erlei M.
Detection, symptoms and symptomless transmission of Drechslera avenae (teleomorph Pyrenophora avenae) from seed were investigated. The present study reported that the D. avenae is frequently found in oat (Avena sativa) seed in Argentina. The prevalence of the seed lot infected was 54%. The incidence of seeds infected by D. avenae in the various seed lots from different regions ranged from 0 to 52% (overall mean of 7%). Besides conidia on conidiophore and immature pseudothecia, D. avenae produced small, spherical to pear-shape picnidia containing tiny conidia, on the seed surface. The pathogen was efficiently transmitted at a rate of 55% from seed to coleoptile tips in symptomless seedlings and at 12.5% to plumules. The importance of the infected seed and...

Detection of areas of endemism on two spatial scales using Parsimony Analysis of Endemicity (PAE): the Neotropical region and the Atlantic Forest
Provedor de dados: 49
Autores: Sigrist,Mário Sérgio; Carvalho,Claudio José Barros de.
An important biological challenge today is the conservation of biodiversity. Biogeography, the study of the distribution patterns of organisms, is an important tool for this challenge. Endemism, the co-occurrence of several species unique to the same area, has important implications for the preservation of biodiversity, since many areas of endemism are also areas with large human impact. More rigorously defined, areas of endemism are historical units of distributional congruence of monophyletic taxa. These areas often assumed to be due to nonrandom historical events that favored conditions associated with high rates of speciation. Thus, understanding endemism and the delimitation of endemic areas has important implications for conservation. Today, most...

Autores: Nikbakhtzadeh,M. R.; Ebramihi,B.
Cantharidin is mainly found in the beetle families Meloidae and Oedemeridae (Insecta: Coleoptera) which are the natural producers of this terpene anhydride. Most studies to date have focused on cantharidin distribution in blister beetles, with few reports on recently found cantharidin-related compounds (CRCs). Using gas chromatography-mass spectrometry (GC-MS), the present work reported cantharidin and two CRCs, palasonin and cantharidinimide from Mylabris impressa stillata (Baudi, 1878) which was collected from Toyserkan county, Hamedan Province, Iran. Ionization provided mass spectra with characteristic fragments of cantharidin at m/z 96 and 128, demethylcantharidin at m/z 82 and 114, and cantharidinimide at m/z 70, 96 and 127.

Cryptosporidium is an emergent pathogen that causes profuse diarrhea in humans. Outbreaks of human cryptosporidiosis have implicated water as a possible source of contamination. In this study the presence of Cryptosporidium sp. oocysts was investigated as well as the fecal contamination in groundwater for consumption in Itaquaquecetuba - São Paulo. Therefore, it was possible to notice that the septic tanks were located close to the wells, exposing them to risk of contamination. As a consequence of these results and observations efficient disinfecting practices and groundwater monitoring are recommended.

Detection of immunoglobulin G in the lung and liver of hamsters with visceral leishmaniasis
Provedor de dados: 56
Autores: Mathias,R.; Costa,F.A.L.; Goto,H.
Several organs are affected in visceral leishmaniasis, not only those rich in mononuclear phagocytes. Hypergammaglobulinemia occurs during visceral leishmaniasis; anti-Leishmania antibodies are not primarily important for protection but might be involved in the pathogenesis of tissue lesions. The glomerulonephritis occurring in visceral leishmaniasis has been attributed to immune complex deposition but in other organs the mechanism has not been studied. In the current study we demonstrated the presence of IgG in the lung and liver of hamsters with visceral leishmaniasis. Hamsters were injected intraperitoneally with 2 x 10(7) amastigotes of Leishmania (Leishmania) chagasi and the presence of IgG in the liver and lung was evaluated at 7, 15, 30, 45, 80 and...

This paper reports what is apparently the first observation of Mycoplasma pneumoniae in association with Chlamydia pneumoniae in thrombosed ruptured atheromas. We performed electron microscopy and in situ hybridization in specimens from three patients who died of acute myocardial infarction. These patients had typical symptoms of acute ischemic syndrome. Mycoplasmas were present mainly in the lipid core of the ruptured thrombosed plaque. Vulnerable atheromas are rich in cholesterol and may favor the growth of mycoplasmas, the only microorganisms that require cholesterol for survival. We suggest that the association of Mycoplasma pneumoniae and Chlamydia pneumoniae may increase the virulence of these microorganisms, favoring proliferation, plaque...

Detection of point mutations by non-isotopic single strand conformation polymorphism
Provedor de dados: 56
Autores: Pinheiro,N.A.; Moura,R.P.; Monteiro,E.; Villa,L.L.
We have developed a procedure for nonradioactive single strand conformation polymorphism analysis and applied it to the detection of point mutations in the human tumor suppressor gene p53. The protocol does not require any particular facilities or equipment, such as radioactive handling, large gel units for sequencing, or a semiautomated electrophoresis system. This technique consists of amplification of DNA fragments by PCR with specific oligonucleotide primers, denaturation, and electrophoresis on small neutral polyacrylamide gels, followed by silver staining. The sensitivity of this procedure is comparable to other described techniques and the method is easy to perform and applicable to a variety of tissue specimens.

Activation of Th1 or Th2 cells is associated with production of specific immunoglobulin isotypes, offering the opportunity to use antibody measurement for evaluation of T cell function. Schistosomiasis and visceral leishmaniasis are diseases associated with Th2 activation. However, an IgE response is not always detected in these patients. In the present study we evaluated specific IgE antibodies to S. mansoni and L. chagasi antigens by ELISA after depletion of serum IgG with protein G immobilized on Sepharose beads or RF-absorbent (purified sheep IgG antibodies anti-human IgG). In schistosomiasis patients, specific IgE to SWAP antigen was demonstrable in only 10 of 21 patients (48%) (mean absorbance ± SD = 0.102 ± 0.195) when unabsorbed serum was used....

Autores: Colariccio,Addolorata; Chaves,Alexandre L.R.; Eiras,Marcelo; Chagas,César M.; Roggero,Piero.
During surveys undertaken from 1998 to 2003 in the major vegetable growing areas of the city of São Paulo green belt, lettuce (Lactuca sativa) and endive (Cichorium endivia) plants were observed, which showed chlorotic thickening of foliar veins, defective growth and, in some cases, failure to form complete heads. Biological and serological [DAS-Enzyme linked immunosorbent assay (Elisa)] tests together with electron microscope observations, revealed the presence of Lettuce big-vein virus and Mirafiori lettuce virus, in these plants both responsible for the lettuce big-vein syndrome.

Autores: CARVALHO,ALFREDO O.R. DE; VIEIRA,LUIZ G.E.
A técnica PCR-RAPD tem sido amplamente empregada em estudos genéticos de populações de vários organismos. Entretanto, devido às interações entre os componentes da reação de PCR é improvável que uma única condição de amplificação possa ser adequada para todas as situações. Com o objetivo de determinar as condições ótimas para a utilização da técnica PCR-RAPD em análises taxonômicas do gênero Atta, foram analisados os fatores: concentrações de MgCl2, DNA, BSA, programas de temperaturas e métodos de extração de DNA, utilizando-se os delineamentos Fatorial Fracionado e o Central Composto. Dentre os fatores avaliados, o método de extração de DNA teve pouca influência na reação, enquanto que o programa de temperatura apresentou o maior efeito. Embora a...

Determination of anaerobic threshold in rats using the lactate minimum test
Provedor de dados: 56
Autores: Voltarelli,F.A.; Gobatto,C.A.; Mello,M.A.R. de.
The break point of the curve of blood lactate vs exercise load has been called anaerobic threshold (AT) and is considered to be an important indicator of endurance exercise capacity in human subjects. There are few studies of AT determination in animals. We describe a protocol for AT determination by the "lactate minimum test" in rats during swimming exercise. The test is based on the premise that during an incremental exercise test, and after a bout of maximal exercise, blood lactate decreases to a minimum and then increases again. This minimum value indicates the intensity of the AT. Adult male (90 days) Wistar rats adapted to swimming for 2 weeks were used. The initial state of lactic acidosis was obtained by making the animals jump into the water and...

Determination of macromolecular exchange and PO2 in the microcirculation: a simple system for in vivo fluorescence and phosphorescence videomicroscopy
Provedor de dados: 56
Autores: Torres,L.N.; Torres Filho,I.P.
We have developed a system with two epi-illumination sources, a DC-regulated lamp for transillumination and mechanical switches for rapid shift of illumination and detection of defined areas (250-750 µm²) by fluorescence and phosphorescence videomicroscopy. The system permits investigation of standard microvascular parameters, vascular permeability as well as intra- and extravascular PO2 by phosphorescence quenching of Pd-meso-tetra (4-carboxyphenyl) porphine (PORPH). A Pechan prism was used to position a defined region over the photomultiplier and TV camera. In order to validate the system for in vivo use, in vitro tests were performed with probes at concentrations that can be found in microvascular studies. Extensive in vitro evaluations were performed...

Provedor de dados: 56
Autores: Dos Santos,L.; Mello,A.F.S.; Antonio,E.L.; Tucci,P.J.F.
Triphenyltetrazolium chloride (TTC) staining and echocardiography (ECHO) are methods used to determine experimental myocardial infarction (MI) size, whose practical applicability should be expanded. Our objectives were to analyze the accuracy of ECHO in determining infarction size in rats during the first days following coronary occlusion and to test whether a simplified single measurement by TTC correctly indicates MI size, as determined by the average value for multiple slices. Infarction was induced in female Wistar rats by coronary artery occlusion and MI size analysis was performed after the acute (7th day) and chronic periods (after 4 weeks) by ECHO matched with TTC. ECHO and TTC showed similar values of MI size (% of left ventricle perimeter) in...

Determination of the activity of standard anti-tuberculosis drugs against intramacrophage Mycobacterium tuberculosis, in vitro: MGIT 960 as a viable alternative for BACTEC 460
Provedor de dados: 55
Autores: Jhamb,Sarbjit Singh; Goyal,Amit; Singh,Prati Pal.
BACTEC 460 has now been phased out, so the search for an alternative is imperative. We have determined the activity of standard anti-tuberculosis drugs against intramacrophage Mycobacterium tuberculosis, in vitro, by using BACTEC 460 and MGIT 960 methods. The minimum inhibitory concentrations of isoniazid, rifampicin, ethambutol and streptomycin against intracellular M. tuberculosis H37Rv were found to be 0.2, 0.8, 8.0, and 5.0 µg/mL, respectively, by both methods. These results show a significant (p &lt; 0.001) concordance between minimum inhibitory concentrations obtained by these two different methods. MGIT 960 system uses a robust florescence quenching-based oxygen sensor, requires no radioisotope, is safe, and relatively easy to operate. Apparently,...

Determining micro- and mesofaunal composition through the analysis of South American grey fox's feces in two different semiarid habitats
Provedor de dados: 67
Autores: Núñez,María B; Mangione,Antonio.
Information obtained from carnivorous´ scats when used for determining faunal composition in different habitats could be confusing if the carnivore does not depose its feces in the same habitat it is feeding or if the prey's home range is larger than the fox´s foraging habitat. In this study, the use of the presence and frequency of mammalian hair in the feces of the South American grey fox, Pseudalopex griseus, are proposed as indicators of the micro- and mesofaunal composition in two habitats (Creosote bush flats and Sierra) in a semidesert environment in central Argentina. These results are then compared to faunal composition determined by live trapping and tracks. The microfauna present was confirmed by using Sherman live traps, while the mesofauna was...

Determining mutations in G6PC and SLC37A4 genes in a sample of Brazilian patients with glycogen storage disease types Ia and Ib
Provedor de dados: 74
Autores: Carlin,Marcelo Paschoalete; Scherrer,Daniel Zanetti; Tommaso,Adriana Maria Alves De; Bertuzzo,Carmen Silvia; Steiner,Carlos Eduardo.
Glycogen storage disease (GSD) comprises a group of autosomal recessive disorders characterized by deficiency of the enzymes that regulate the synthesis or degradation of glycogen. Types Ia and Ib are the most prevalent; while the former is caused by deficiency of glucose-6-phosphatase (G6Pase), the latter is associated with impaired glucose-6-phosphate transporter, where the catalytic unit of G6Pase is located. Over 85 mutations have been reported since the cloning of G6PC and SLC37A4 genes. In this study, twelve unrelated patients with clinical symptoms suggestive of GSDIa and Ib were investigated by using genetic sequencing of G6PC and SLC37A4 genes, being three confirmed as having GSD Ia, and two with GSD Ib. In seven of these patients no mutations...

We report data showing that developed pressure (DPmax) may lead to opposite conclusion with respect to maximal developed circumferential wall stress (&lt;FONT FACE="Symbol"&gt;s&lt;/FONT&gt;max) when used to assess contractile function in left ventricle isovolumic preparations. Isovolumetric left ventricle preparations of rats with cardiac hypertrophy (H; N = 10) induced by isoproterenol administration showed higher DPmax (174 ± 14 mmHg) than control (C; N = 8) animals (155 ± 12 mmHg) or rats with regression (R; N = 8) of hypertrophy (144 ± 11 mmHg). In contrast, the estimated &lt;FONT FACE="Symbol"&gt;s&lt;/FONT&gt;max for C (145 ± 26 kdynes/cm2) and R (133 ± 17 kdynes/cm2) was higher than for H (110 ± 13 kdynes/cm2).

Background The Amazon as a whole is the largest reservoir of arboviruses worldwide, while the Brazilian Amazon hosts the largest variety of arboviruses isolated to date. In this study, the results of an indirect sandwich IgG ELISA, standardized for 19 arbovirustypes circulating among horses in Brazilian Amazon, were compared to results of the hemagglutination inhibition test. A screening test assessed the conditional probability distribution and a Pearson linear correlation test determined the correlation strength among the absorbance values recorded for viruses from the same family.Findings Sensitivity varied between 40.85 and 100%; the specificity was low and ranged from 39.71 to 67.0%; and the accuracy varied between 41 and 65.2%.

Diagnosis of the fragile X syndrome in males using methylation-specific PCR of the FMRI locus
Provedor de dados: 74
Autores: Pena,Sérgio D.J.; Sturzeneker,Rosane.
We have developed a non-isotopic technique based on methylation-specific PCR (MSP) of the FMR1 promoter for the identification of fragile X full mutations among men. DNA samples were first treated with sodium bisulfite to convert unmethylated, but not methylated, cytosines to uracil, followed by PCR amplification with oligonucleotide primers specific for methylated versus unmethylated DNA. We designed two primer pairs: one produced a 142-bp fragment from the bisulfite-treated methylated CpG island, while the other generated an 84-bp product from the treated non-methylated promoter. In normal males only the 84-bp fragment was seen, while the diagnosis of FRAXA was doubly indicated by the appearance of a 142-bp product together with absence or weak...

Did Sutton and Boveri propose the so-called Sutton-Boveri chromosome hypothesis?
Provedor de dados: 74
Autores: Martins,L.A.-C.P.
The "Sutton-Boveri chromosome hypothesis" attempted to establish a parallel between cytological chromosome behavior and the principles followed by Mendelian factors. Today, this hypothesis is well accepted; however, it was not completely accepted at its proposal (1902-3). The aim of the present study is to elucidate the meaning of the chromosome hypothesis based on the original scientific works, taking into account the scientific context of that time. The negative treatment this hypothesis received is evaluated. I conclude that it was unfair to include Boveri's name beside that of Sutton's as one of the proponents of the chromosome hypothesis of Mendelian heredity, because he did not publish any hypothesis of that kind during the relevant period...

Abstract: The species Boana bischoffi and Boana marginata are endemic to the Atlantic Forest, where they often occur in sympatry. There is a large gap in the knowledge of natural history of both species. In this study, we aimed to describe and compare the diet composition of B. bischoffi and B. marginata in the southern domain of the Brazilian Atlantic Forest. We analyzed the gastrointestinal contents of 43 individuals of B. bischoffi and 30 individuals of B. marginata. Both showed a high trophic niche overlap (0.90 Ojk). The most important prey categories for both species belonged to the orders Araneae and Coleoptera. The species niche breadth (Bsta) varied from 0.35 to 0.42, suggesting a generalist feeding behavior for both species. Our data provide...

Provedor de dados: 49
Autores: Gibran,Fernando Zaniolo; Ferreira,Katiane Mara; Castro,Ricardo M. C.
We qualitatively studied the gut contents of 20 specimens (36.1-71.3 mm standard length) of the pike cichlid Crenicichla britskii from a 100 m stretched second order stream running inside a small gallery forest in a large pasture area of Rio Aguapeí basin, State of São Paulo, southeastern Brazil. The diet, in terms of per cent composition, constituted primarily of aquatic insects (50%) (mostly immature forms), crustaceans (14.3%), unidentified organic material and filamentous green algae (both with 10.7%), followed by fishes and arachnids (both with 7.1%). Diet analysis indicates that C. britskii is a generalist insectivore with a relatively short digestive tube, which feeds on autochthonous items captured in a broad array of habitats such as in the water...

Autores: Bianchi,Rita de Cassia; Rosa,Aline F; Gatti,Andressa; Mendes,Sérgio L.
This study identifies the food habits of the margay, Leopardus wiedii (Schinz, 1821), and the jaguarundi, Puma yagouaroundi (É. Geoffroy Saint-Hilare, 1803), in the Vale do Rio Doce Natural Reserve and in the Sooretama Biological Reserve, Espírito Santo, Brazil. We determined the diet of both species by the analysis of scats. Fecal samples were collected from April 1995 to September 2000 and identified based on the presence of hairs that were ingested during self-grooming. Scats were oven-dried and washed on a sieve, and the screened material was identified using a reference collection. Of the 59 fecal samples examined, 30 were confirmed to be from the margay and nine of them from the jaguarundi. Mammals were the most consumed items in the diet of the...

Diet plus insulin compared to diet alone in the treatment of gestational diabetes mellitus: a systematic review
Provedor de dados: 56
Autores: Giuffrida,F.M.A.; Castro,A.A.; Atallah,A.N.; Dib,S.A.
Fetuses of mothers with gestational diabetes mellitus are at increased risk to develop perinatal complications mainly due to macrosomia. However, in view of the marked heterogeneity of this disease, it seems difficult to set guidelines for diagnosis and treatment. This complicates the choice of assigning patients either to diet or to insulin therapy. Also of concern is how much benefit could be expected from insulin therapy in preventing fetal complications in these patients. In a systematic review of the literature assessing the efficacy of insulin in preventing macrosomia in fetuses of mothers with gestational diabetes, we found six randomized controlled trials comparing diet alone to diet plus insulin. The studies included a total of 1281 patients (644...

Autores: Catani,M.; Amâncio,O.M.S.; Fagundes-Neto,U.; Morais,M.B.
The objective of the present study was to determine the effect of cellulose on intestinal iron absorption in rats during recovery from iron deficiency anemia. Twenty-one-day-old male Wistar-EPM rats were fed an iron-free ration for two weeks to induce anemia. At 5 weeks of age, the rats were divided into two groups (both groups receiving 35 mg of elemental iron per kg diet): cellulose group (N = 12), receiving a diet containing 100 g of cellulose/kg and control (N = 12), receiving a diet containing no cellulose. The fresh weight of the feces collected over a 3-day period between the 15th and 18th day of dietary treatment was 10.7 ± 3.5 g in the group receiving cellulose and 1.9 ± 1.2 g in the control group (P&lt;0.001).

This study was conducted to verify the effects of dietary crude protein reduction on growth and carcass performance of 22-42-day-old broilers reared under different temperatures. Treatments were set up in a five by two factorial arrangement, with five crude protein levels (220, 210, 200, 190 and 184 g/kg) and two temperatures (21.6 and 32.2 ºC). Diets were isocaloric and essential amino acid-to-lysine ratio was maintained constant in all treatments. There was no interaction between crude protein reduction and environmental temperature for any of the parameters evaluated. Crude protein had no influence on feed intake. Nevertheless, weight gain and feed conversion ratio were linearly influenced by crude protein reduction. Worse performance was also observed...

Autores: De Souza,R.R.; Gama,E.F.; Silva,R.D.A.; Heimann,J.C.; Maifrino,L.B.M.; Liberti,E.A.
In the present study we investigated the effect of salt intake on myenteric neuron size of the colon of adult male Wistar rats. The animals were placed on either a high-salt (HS; 8%; 12 animals) or a low-salt diet (LS; 0.15%; 12 animals) for 15 or 52 weeks and blood pressure was measured. The sizes of myenteric neurons of the distal colon from both groups were measured. No difference in neuron size was observed between the HS and LS groups after 15 weeks. After 52 weeks on HS, neuron size was increased (P&amp;lt;0.005) when compared with the LS group. The rats also presented hypertension, which was significantly different at 52 weeks (142 ± 11 vs 119 ± 7 mmHg). These results suggest that a long time on an HS diet can significantly increase myenteric nerve...

Autores: CASELA,CARLOS R.; FERREIRA,ALEXANDRE S.; SANTOS,FREDOLINO G.
Mixtures of races of Colletotrichum graminicola, causing sorghum (Sorghum bicolor) anthracnose and differing in their virulence range, were inoculated for five and six generations on the susceptible sorghum cultivar BR009 (Tx623), in two experiments in a greenhouse. In each generation a sample of 50 single spore isolates was obtained and inoculated on a standard differential set to determine the proportion of each race in the mixture. Isolates of the race 30A, with the narrowest virulence range, predominated over isolates of the more complex races 31B, 31C and 31E indicating the existence of differences in the survival ability among races of this pathogen.

Differences in larval emergence chronotypes for sympatric Rhagoletis brncici Frías and Rhagoletis conversa (Bréthes) (Diptera, Tephritidae)
Provedor de dados: 92
Autores: Frías-Lasserre,Daniel; S,Andrea Luna; Villagra,Cristian A.
ABSTRACT In central Chile, Rhagoletis brncici and R. conversa, can be found in sympatry, associated with the fruit of their native host plants: Solanum tomatillo and S. nigrum (Solanaceae), respectively. Third-stage larvae must emerge from its host in search of pupation sites, and during this period larvae must find an appropriate pupation microhabitat while avoiding predation and adverse abiotic factors. In this study, we explored whether these sympatric species differ in terms of the timing of their larval exit from the host fruit in search of pupation sites. Field-collected fruits from host plants were checked daily for larval emergence, within 24 h, under laboratory conditions, in order to determine the time of the event. We found that these species...

Different responses of the GlnB and GlnZ proteins upon in vitro uridylylation by the Azospirillum brasilense GlnD protein
Provedor de dados: 56
Autores: Araújo,L.M.; Huergo,L.F.; Invitti,A.L.; Gimenes,C.I.; Bonatto,A.C.; Monteiro,R.A.; Souza,E.M.; Pedrosa,F.O.; Chubatsu,L.S.
Azospirillum brasilense is a diazotroph found in association with important agricultural crops. In this organism, the regulation of nitrogen fixation by ammonium ions involves several proteins including the uridylyltransferase/uridylyl-removing enzyme, GlnD, which reversibly uridylylates the two PII proteins, GlnB and GlnZ, in response to the concentration of ammonium ions. In the present study, the uridylylation/deuridylylation cycle of A. brasilense GlnB and GlnZ proteins by GlnD was reconstituted in vitro using the purified proteins. The uridylylation assay was analyzed using non-denaturing polyacrylamide gel electrophoresis and fluorescent protein detection. Our results show that the purified A. brasilense GlnB and GlnZ proteins were uridylylated by...

Differential effects of isoproterenol on the activity of angiotensin-converting enzyme in the rat heart and aorta
Provedor de dados: 56
Autores: Busatto,V.C.W.; Cunha,V.; Cicilini,M.A.; Mill,J.G.
The excessive stimulation of beta-adrenergic receptors in the heart induces myocardial hypertrophy. There are several experimental data suggesting that this hypertrophy may also depend, at least partially, on the increase of local production of angiotensin II secondary to the activation of the cardiac renin-angiotensin system. In this study we investigated the effects of isoproterenol on the activity of angiotensin-converting enzyme (ACE) in the heart and also in the aorta and plasma. Male Wistar rats weighing 250 to 305 g were treated with a dose of (±)-isoproterenol (0.3 mg kg-1 day-1, N = 8) sufficient to produce cardiac hypertrophy without deleterious effects on the pumping capacity of the heart. Control rats (N = 7) were treated with vehicle (corn...

Autores: de Oliveira,F.S.; Viana,M.R.; Antoniolli,A.R.; Marchioro,M.
We studied the effects of chronic intoxication with the heavy metals lead (Pb2+) and zinc (Zn2+) on memory formation in mice. Animals were intoxicated through drinking water during the pre- and postnatal periods and then tested in the step-through inhibitory avoidance memory task. Chronic postnatal intoxication with Pb2+ did not change the step-through latency values recorded during the 4 weeks of the test (ANOVA, P&gt;0.05). In contrast, mice intoxicated during the prenatal period showed significantly reduced latency values when compared to the control group (day 1: q = 4.62, P&lt;0.05; day 7: q = 4.42, P&lt;0.05; day 14: q = 5.65, P&lt;0.05; day 21: q = 3.96, P&lt;0.05, and day 28: q = 6.09, P&lt;0.05).

Provedor de dados: 56
Autores: Batista,S.S.; Pires,R.S.; Britto,L.R.G.
Glutamate receptors have been often associated with developmental processes. We used immunohistochemical techniques to evaluate the expression of the AMPA-type glutamate receptor (GluR) subunits in the chick optic tectum (TeO). Chick embryos from the 5th through the 20th embryonic day (E5-E20) and one-day-old (P1) chicks were used. The three types of immunoreactivity evaluated (GluR1, GluR2/3, and GluR4) had different temporal and spatial expression patterns in the several layers of the TeO. The GluR1 subunit first appeared as moderate staining on E7 and then increased on E9. The mature GluR1 pattern included intense staining only in layer 5 of the TeO. The GluR2/3 subunits presented low expression on E5, which became intense on E7. The staining for...

We studied the effects of infusion of nerve growth factor (NGF) into the hippocampus and entorhinal cortex of male Wistar rats (250-300 g, N = 11-13 per group) on inhibitory avoidance retention. In order to evaluate the modulation of entorhinal and hippocampal NGF in short- and long-term memory, animals were implanted with cannulae in the CA1 area of the dorsal hippocampus or entorhinal cortex and trained in one-trial step-down inhibitory avoidance (foot shock, 0.4 mA). Retention tests were carried out 1.5 h or 24 h after training to measure short- and long-term memory, respectively. Immediately after training, rats received 5 µl NGF (0.05, 0.5 or 5.0 ng) or saline per side into the CA1 area and entorhinal cortex. The correct position of the cannulae was...

Digestive and regenerative cells in the midgut of haploid and diploid males of the stingless bee Melipona quadrifasciata anthidioides (Hymenoptera: Apidae)
Provedor de dados: 103
Autores: Fernandes,Kenner M.; Martins,Gustavo F.; Serrão,José E.; Neves,Clóvis A.
In eusocial bees, workers and queens are diploid (2n), whereas males are haploid (n). However, in some species, including the stingless bee Melipona quadrifasciata anthidioides Lepeletier, 1836, 2n males arise from fertilized eggs resulting from the crossing between a queen and her brother. In the present study, we provide a comparative analysis of the digestive and regenerative cells in n and 2n pupae and adult males of M. quadrifasciata anthidioides. In n and 2n pupae and adult males, the number of regenerative cells/nest was similar. In n and 2n pupae, the mean number of digestive cells/midgut area was 2076 ± 0.60, whereas in adults it was 1234 ± 1.42 digestive cells/midgut area. The nuclear area of the digestive cells was also similar in both n and 2n...

In 1999, a case of diphtheria in a 32-year-old woman was reported. The patient developed a sore throat immediately after participating of a five-day meeting with European workers in Rio de Janeiro. Her history included complete pediatric immunization (DTP) and three doses of adult formulation tetanus and diphtheria toxoid (dT) two years earlier. Clinical diagnosis of diphtheria was not made until microbiologic examination of specimens confirmed toxigenicity of Corynebacterium diphtheriae var. gravis, a biotype currently found circulating within Europe where diphtheria remains epidemic. This case reinforces the potential susceptibility of Brazilian adults to epidemic diphtheria in the vaccine era.

Serologic data on diseases that are preventable by vaccines are necessary to evaluate the success of immunization programs and to identify susceptible subgroups. In the present study, we determined serum IgG levels against diphtheria toxin of military and civilian blood donors (N = 75; 69.3% males and 30.7% females) aged 18-64 years, from the Brazilian Army Biology Institute, Rio de Janeiro, using a commercial diphtheria kit (Diphtheria IgG ELISA; IBL, Germany). Most (63%) unprotected military donors were from the older age group of 41 to 64 years. In contrast, the majority (71%) of young military donors (18 to 30 years) were fully protected. About half of the military donors aged 31 to 40 years were protected against diphtheria. Among the civilians, about...

ABSTRACT Bloodstream infections (BSIs) are among the most concerning bacterial infections. They are one of the leading causes of morbidity and mortality, and occur in 30-70% of critical care patients. The prompt identification of the causative microorganism can help choosing the appropriate antimicrobial therapy that will lead to better clinical outcomes. Blood culture is one of the most relevant tests for microbiological diagnosis of bacterial infections. The introduction of the MALDI-TOF microbiological diagnosis significantly decreased the time of identifying microorganisms. However, it depends on the growth on solid culture medium. In this study, 538 bottles of positive blood cultures were evaluated to test the accuracy of an in house modified...

Scinax aromothyella is a recently described hylid frog. Its distribution is not well known. There are records for Misiones, Argentina and for southeastern Uruguay. Here we report a new record of S. aromothyella from Aceguá, Cerro Largo Department, Uruguay (31° 53' 39" S and 54° 9' 17" W), based in tadpoles collected on the 15 of August, 2007. This new record extends the distribution of S. aromothyella in approximately 100 km north from previous reports in Uruguay. The samples were collected in a site located 2 km away from the border line with Brazil, reinforcing the idea that S. aromothyella might occur in Rio Grande do Sul.

Hepatitis C virus (HCV) infection is widespread and responsible for more than 60% of chronic hepatitis cases. HCV presents a genetic variability which has led to viral classification into at least 6 genotypes and a series of subtypes. These variants present characteristic geographical distribution, but their association with different responses to treatment with interferon and severity of disease still remains controversial. The aim of this study was to investigate the patterns of distribution of HCV genotypes among different exposure categories in Brazil. Two hundred and fifty anti-HCV positive samples were submitted to HCV-RNA detection by RT-PCR and their genotype was determined by restriction fragment length polymorphism (RFLP) analysis. In addition,...

The achievement of complete cure in dogs with visceral leishmaniasis is currently a great challenge, since dogs are the main reservoir for the transmission of visceral leishmaniasis to humans and they respond poorly to conventional treatment with pentavalent antimonials. In order to improve the efficacy of treatment, we developed a novel formulation for meglumine antimoniate based on the encapsulation of this drug in freeze-dried liposomes (LMA). The aim of the present study was to evaluate the biodistribution of antimony (Sb) in dogs following a single intravenous bolus injection of LMA. Four healthy male mongrel dogs received LMA at 3.8 mg Sb/kg body weight and were sacrificed 3, 48 and 96 h and 7 days later. Antimony was determined in the blood, liver,...

A mutation described as a G-to-A transition has been reported in SDF-1 gene (SDF1-3'A), being prevalent in all ethnic groups, except in Africans. This mutation is associated with the onset of AIDS progression. Our aim was to identify the frequency of this allele in different groups from Brazil: Tiriyó and Waiampi Amerindian tribes (Asian ancestry); selected blood donors from Joinville (German descendents); and from Salvador (predominance of African and Portuguese mixture). SDF1-3'A was screened by PCR/RFLP with MspI enzyme. Our results showed a high allelic frequency in Tiriyó tribe (0.24) and Joinville population (0.21), and a frequency of 0.17 and 0.05 in the Salvador population and in the Waiampi tribe, respectively. There was no statistical difference...

Distribution of water in sandy soil applied by drip
Provedor de dados: 70
Autores: Gonçalves,Antônio C. A.; Alves,Daniel S.; Marques,Patricia A. A.; Folegatti,Marcos V.; José,Jefferson V.
The search for the use of water with high levels of efficiency has motivated the use of drip irrigation in several agricultural systems. However, for the efficiency be ensured, it is necessary that the water distribution in the soil profile must to be known in more details. As it is a highly variable process, function of the local characteristics, is essential the study of each case. The objective of this research was evaluating the water distribution in the soil profile, from drippers installed in surface and 0.15 m below the soil surface. The experiment was realized in the Technical Center of Irrigation (TCI) of the State University of Maringá - PR. The water monitoring in the soil profile was done with TDR probes installed in a box containing sandy...

Diurnal frugivores on the Bromeliaceae Aechmea depressa L.B. Sm. from Northeastern Brazil: the prominent role taken by a small forest primate
Provedor de dados: 49
Autores: Fontoura,Talita; Cazetta,Eliana; Nascimento,Wander do; Catenacci,Lilian; De Vleeschouwer,Kristel; Raboy,Becky.
Little is known about frugivory of epiphytes. We investigated diurnal frugivores consuming Aechmea depressa, an endemic species from Southern Bahia, Brazil, through 67 hours of observation on three fruiting individuals. Infructescences were visited for 2% of the time and only by golden-headed lion tamarins (GHLTs; Leontopithecus chrysomelas). Aechmea depressa invests on physical defense to retain fruits for prolonged periods, however, GHLTs used their small size and dexterity to remove rigid bracts and extract fruits from the infructescence. Prior studies indicate GHLTs disperse Aechmea seeds. Given the low visitation rates and probability that few frugivores successfully manipulate A. depressa fruits, we suggest that GHLTs are extremely important to...

Diversity among satellite glial cells in dorsal root ganglia of the rat
Provedor de dados: 56
Autores: Nascimento,R.S.; Santiago,M.F.; Marques,S.A.; Allodi,S.; Martinez,A.M.B.
Peripheral glial cells consist of satellite, enteric glial, and Schwann cells. In dorsal root ganglia, besides pseudo-unipolar neurons, myelinated and nonmyelinated fibers, macrophages, and fibroblasts, satellite cells also constitute the resident components. Information on satellite cells is not abundant; however, they appear to provide mechanical and metabolic support for neurons by forming an envelope surrounding their cell bodies. Although there is a heterogeneous population of neurons in the dorsal root ganglia, satellite cells have been described to be a homogeneous group of perineuronal cells. Our objective was to characterize the ultrastructure, immunohistochemistry, and histochemistry of the satellite cells of the dorsal root ganglia of 17 adult...

The genomes of 10 equine herpesvirus 1 (EHV-1) strains isolated in Argentina from 1979 to 1991, and a Japanese HH1 reference strain were compared by restriction endonuclease analysis. Two restriction enzymes, BamHI and BglII, were used and analysis of the electropherotypes did not show significant differences among isolates obtained from horses with different clinical signs. This suggests that the EHV-1 isolates studied, which circulated in Argentina for more than 10 years, belong to a single genotype.

Gamma-glutamyltranspeptidase (GGT-EC 2.3.2.2) activity and glutathione (GSH) content were measured in livers of female weanling Wistar rats (N = 5-18), submitted to rice-and-bean diets (13 and 6% w/w protein), both supplemented or not with DL-methionine (0.5 and 0.23 g/100 g dry diet, respectively). After 28 days, the rats on the rice-and-bean diets showed significantly higher levels (four times higher) of liver GGT activity and a concomitant 50% lower concentration of liver GSH in comparison with control groups feeding on casein. The addition of DL-methionine to rice-and-bean diets significantly increased the liver GSH content, which reached levels 50% higher than those found in animals on casein diets. The increase in GSH was accompanied by a decrease in...

ABSTRACT The tropical anguillid eel, Anguilla bicolor McCelland, 1844, includes two subspecies, Anguilla bicolor bicolor McCelland, 1844 and Anguilla bicolor pacifica Schmidt, 1928, and is distributed across the Indo-Pacific region. Although A. bicolor is widely distributed and recognized as an important fish resource in the Indo-Pacific region, few studies have been conducted on its genetic variation and population structure. DNA barcoding of A. bicolor specimens collected in the Indo-Pacific region was carried out in this study using mitochondrial cytochrome c oxidase subunit I. Anguilla bicolor was found to diverge genetically, which supported its classification into two different subspecies. In addition, our study showed that A. bicolor bicolor had two...

Autores: Choudhary,Vivek; Kumar,Pushpendra; Bhattacharya,Tarun K.; Bhushan,Bharat; Sharma,Arjava.
Leptin plays an important role in the regulation of feed intake, energy metabolism, growth and reproduction of cattle. We used the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique to screen for DNA polymorphisms of the leptin gene in 403 cattle belonging to various breeds of Bos indicus (Hariana, Sahiwal, Gir and Nimari cattle), Bos taurus (Holstein Friesian (HF) and Jersey cattle) as well as Bos taurus x Bos indicus crossbreds (½ HF x ½ Hariana). In all the cattle we amplified two regions of the leptin gene, a 522 bp fragment comprising the partial intron 2 and exon 3 and another 94 bp fragment consisting of part of exon 2. Digestion of 522 bp PCR products with the BsaAI restriction enzyme revealed three genotypes in...

Autores: Grynberg,N.F.; Carvalho,M.G.; Velandia,J.R.; Oliveira,M.C.; Moreira,I.C.; Braz- Filho,R.; Echevarria,A.
Topoisomerase inhibitors are agents with anticancer activity. 7"-O-Methyl-agathisflavone (I) and amentoflavone (II) are biflavonoids and were isolated from the Brazilian plants Ouratea hexasperma and O. semiserrata, respectively. These biflavonoids and the acetyl derivative of II (IIa) are inhibitors of human DNA topoisomerases I at 200 µM, as demonstrated by the relaxation assay of supercoiled DNA, and only agathisflavone (I) at 200 µM also inhibited DNA topoisomerases II-alpha, as observed by decatenation and relaxation assays. The biflavonoids showed concentration-dependent growth inhibitory activities on Ehrlich carcinoma cells in 45-h culture, assayed by a tetrazolium method, with IC50 = 24 ± 1.4 µM for I, 26 ± 1.1 µM for II and 10 ± 0.7 µM for IIa....

Autores: Barbosa,A.A.; Pedrazzoli,M.; Koike,B.D.V.; Tufik,S.
The Period 3 and Clock genes are important components of the mammalian molecular circadian system. Studies have shown association between polymorphisms in these clock genes and circadian phenotypes in different populations. Nevertheless, differences in the pattern of allele frequency and genotyping distribution are systematically observed in studies with different ethnic groups. To investigate and compare the pattern of distribution in a sample of Asian and Caucasian populations living in Brazil, we evaluated two well-studied polymorphisms in the clock genes: a variable number of tandem repeats (VNTR) in PER3 and a single nucleotide polymorphism (SNP) in CLOCK. The aim of this investigation was to search for clues about human evolutionary processes related...

Do we underestimate the impact of roads on arboreal animals? Roadkill as an important threat to Chaetomys subspinosus (Mammalia: Rodentia)
Provedor de dados: 49
Autores: Srbek-Araujo,Ana Carolina; Alvarenga,Aline de Castro; Bertoldi,Ariane Teixeira.
Abstract: The Thin-spined Porcupine (Chaetomys subspinosus) is a medium-sized and mainly arboreal rodent, endemic to the Brazilian Atlantic Forest, and threatened with extinction. Habitat loss, hunting, forest fires, agriculture and livestock are threats identified for the species. Here we raise the alert to the impact of roads on remaining populations of C. subspinosus based on roadkill records from the state of Espírito Santo, southeastern Brazil. Mortality due to roadkill is likely to impact C. subspinosus in different regions of the state, and is a widespread problem, not unique to a single location or population. The pattern of roadkills in the studied regions suggest that the species is more susceptible to collisions with vehicles in the breeding...

Um período de incubação de cinco dias significa, no contexto da epidemiologia de doenças de plantas, que as infecções que deram origem aos sintomas visualizados no tempo t ocorreram no tempo t-5. Há um grupo de doenças, no entanto, que se comporta de modo diferente, isto é, o momento da infecção não pode ser inferido a partir da visualização dos sintomas. Esse grupo de doenças pode ser dividido, para fins didáticos, em função do órgão da planta que exibe os sintomas: (i) brotações jovens; (ii) perfilhos jovens; (iii) frutos recém-amadurecidos. Nesses três subgrupos, a expressão dos sintomas é função do estádio fenológico do órgão afetado e tem pouca relação com o momento da infecção.

Does habitat specificity by frugivorous birds result in uneven seed rain within Bolivian mixed plantations?
Provedor de dados: 67
Autores: Montaño-Centellas,Flavia A.
Small-scale habitat specificity by frugivorous birds might affect their patterns of use of space and, consequently, may influence the range of habitats over which seeds are disseminated. These differences may translate into non-redundancy among bird assemblages using different habitats. I tested this hypothesis by capturing birds in two habitats within shaded mixed plantations in a Bolivian Andean forest (plantation interior and plantation edges with the forest matrix) and comparing the seeds found in their droppings. I found that, despite differences in bird assemblage composition and activity, the overall seed rain was similar among habitats: the seed rain in edges was only slightly richer in species than in the plantation interior, but species...

ABSTRACT We compared the discriminatory capacity of the sequential organ failure assessment (SOFA) versus the systemic inflammatory response syndrome (SIRS) score for predicting ICU mortality, need for and length of mechanical ventilation, ICU stay, and hospitalization in patients with suspected infection admitted to a mixed Brazilian ICU. We performed a retrospective analysis of a longitudinal ICU database from a tertiary hospital in Southern Brazil. Patients were categorized according to whether they met the criteria for sepsis according to SOFA (variation ≥2 points over the baseline clinical condition) and SIRS (SIRS score ≥2 points). From January 2008 to December 2014, 1487 patients were admitted to the ICU due to suspected infection. SOFA ≥2...

Dopamine constitutes about 80% of the content of central catecholamines and has a crucial role in the etiology of several neuropsychiatric disorders, including Parkinson's disease, depression and schizophrenia. Several dopaminergic drugs are used to treat these pathologies, but many problems are attributed to these therapies. Within this context, the search for new more efficient dopaminergic agents with less adverse effects represents a vast research field. The aim of the present study was to report the structural design of two N-phenylpiperazine derivatives, compound 4: 1-[1-(4-chlorophenyl)-1H-4-pyrazolylmethyl]-4-phenylhexahydropyrazine and compound 5: 1-[1-(4-chlorophenyl)-1H-1,2,3-triazol-4-ylmethyl]-4-phenylhexahydropyrazine, planned to be dopamine...

Dormición y tipo de suelo como determinantes de la germinación y establecimiento de Chloris berroi en la Pampa Deprimida
Provedor de dados: 67
Autores: Bolaños,Víctor A.; Vecchio,M. Cristina; Golluscio,Rodolfo A.
En los pastizales halófitos de la Pampa Deprimida la historia pastoril habría inducido deterioros en la diversidad florísticos y propiedades edáficas. La recuperación de las especies nativas de alto valor forrajero constituye una valiosa estrategia para la regeneración forrajera del sistema. Ello requiere un profundo conocimiento de los aspectos ecológicos de estas especies que, en el caso de Chloris berroi, nativa y potencial regeneradora de ambientes degradados, es desconocido. En este trabajo evaluamos dos hipótesis: (1) la dormición de C. berroi se debe a las estructuras que recubren la cariópside e inhiben su germinación durante un cierto período después de la cosecha y (2) el establecimiento de plántulas de C. berroi es afectado por el tipo de suelo....

The in vitro ability of Pothomorphe umbellata ethanolic crude extract to inhibit matrix metalloproteinase (MMP) in normal cornea and in cornea after alkali injury was demonstrated. Corneas of albino rabbits were injured with 1 N NaOH for 20 s. After 48 h the corneas were excised, homogenized and analyzed for MMP-9 (92 kDa), pro-MMP-2 (72 kDa) and MMP-2 (67 kDa) activity by gelatin zymography. The activity was also measured in untreated corneas. After electrophoresis of 20 µg protein, gels were incubated with 50, 100, or 250 µg/mL lyophilized hydroethanolic (1:1) root crude extract of P. umbellata standardized for 4-nerolidylcatechol (7.09%). The activity of the enzymes was compared with that of untreated gel. At 48 h after injury, the activity of all MMPs...

Autores: Cechin,E.M.; Quevedo,J.; Barichello,T.; Machado-Vieira,R.; Gentil,V.; Kapczinski,F.
We evaluated the effects of the neuroleptic agent propericiazine on animal models of anxiety and memory. Adult male Wistar rats (250 to 350 g) received intraperitoneal injections of propericiazine (0.05, 0.075 and 0.1 mg/kg), diazepam (1 mg/kg), saline, or diazepam vehicle (20% propylene glycol and 80% saline) 30 min prior to the experimental procedure. Animals (10-15 for each task) were tested for step-down inhibitory avoidance (0.3-mA footshock) and habituation to an open-field for memory assessment, and submitted to the elevated plus-maze to evaluate the effects of propericiazine in a model of anxiety. Animals treated with 0.075 mg/kg propericiazine showed a reduction in anxiety measures (P&lt;0.05) similar to that observed in those treated with...

Dose-response effects of systemic anandamide administration in mice sequentially submitted to the open field and elevated plus-maze tests
Provedor de dados: 56
Autores: Ribeiro,A.; Ferraz-de-Paula,V.; Pinheiro,M.L.; Palermo-Neto,J.
The endocannabinoid system is involved in the control of many physiological functions, including the control of emotional states. In rodents, previous exposure to an open field increases the anxiety-like behavior in the elevated plus-maze. Anxiolytic-like effects of pharmacological compounds that increase endocannabinoid levels have been well documented. However, these effects are more evident in animals with high anxiety levels. Several studies have described characteristic inverted U-shaped dose-response effects of drugs that modulate the endocannabinoid levels. However, there are no studies showing the effects of different doses of exogenous anandamide, an endocannabinoid, in animal models of anxiety. Thus, in the present study, we determined the...

Double-blind trial of the efficacy of pentoxifylline vs thalidomide for the treatment of type II reaction in leprosy
Provedor de dados: 56
Autores: Sales,A.M.; Matos,H.J.de; Nery,J.A.C.; Duppre,N.C.; Sampaio,E.P.; Sarno,E.N.
Type II reaction in leprosy, or erythema nodosum leprosum (ENL), is often characterized by severe clinical symptoms together with nerve function impairment leading to permanent disabilities. Thalidomide has been shown to be a highly effective drug for the treatment of ENL. It is, however, contraindicated for women of childbearing age due to its teratogenicity. On the other hand, pentoxifylline, used to treat hypercoagulable states, is not teratogenic and, like thalidomide, can inhibit the synthesis of tumor necrosis factor-a and other cytokines. In the present randomized double-blind clinical study we compared the effectiveness of orally administered pentoxifylline vs thalidomide in treating type II reaction in 44 patients. Daily doses of 300 mg...

We have shown that myocardial dysfunction induced by food restriction is related to calcium handling. Although cardiac function is depressed in food-restricted animals, there is limited information about the molecular mechanisms that lead to this abnormality. The present study evaluated the effects of food restriction on calcium cycling, focusing on sarcoplasmic Ca2+-ATPase (SERCA2), phospholamban (PLB), and ryanodine channel (RYR2) mRNA expressions in rat myocardium. Male Wistar-Kyoto rats, 60 days old, were submitted to ad libitum feeding (control rats) or 50% diet restriction for 90 days. The levels of left ventricle SERCA2, PLB, and RYR2 were measured using semi-quantitative RT-PCR. Body and ventricular weights were reduced in 50% food-restricted...

Abstract The strain BR 3262 was isolated from nodule of cowpea (Vigna unguiculata L. Walp) growing in soil of the Atlantic Forest area in Brazil and it is reported as an efficient nitrogen fixing bacterium associated to cowpea. Firstly, this strain was assigned as Bradyrhizobium elkanii, however, recently a more detailed genetic and molecular characterization has indicated it could be a Bradyrhizobium pachyrhizi species. We report here the draft genome sequence of B. pachyrhizi strain BR 3262, an elite bacterium used as inoculant for cowpea. The whole genome with 116 scaffolds, 8,965,178 bp and 63.8% of C+G content for BR 3262 was obtained using Illumina MiSeq sequencing technology. Annotation was added by the RAST prokaryotic genome annotation service and...

Early myelin breakdown following sural nerve crush: a freeze-fracture study
Provedor de dados: 56
Autores: Martinez,A.M.B.; Canavarro,S.
In this study we describe the early changes of the myelin sheath following surgical nerve crush. We used the freeze-fracture technique to better evaluate myelin alterations during an early stage of Wallerian degeneration. Rat sural nerves were experimentally crushed and animals were sacrificed by transcardiac perfusion 30 h after surgery. Segments of the nerves were processed for routine transmission electron microscopy and freeze-fracture techniques. Our results show that 30 h after the lesion there was asynchrony in the pattern of Wallerian degeneration, with different nerve fibers exhibiting variable degrees of axon disruption. This was observed by both techniques. Careful examination of several replicas revealed early changes in myelin membranes...

Early-onset breast cancer patients in the South and Southeast of Brazil should be tested for the TP53 p.R337H mutation
Provedor de dados: 74

Abstract Germline TP53 mutations are associated with Li-Fraumeni syndrome (LFS), a disease that predisposes carriers to a wide variety of early onset tumors. In southern and southeastern Brazil, a high frequency of a germline TP53 mutation, p.R337H, was diagnosed in 0,3% of the population due to a founder effect. Carriers are at risk for developing cancer but the penetrance is lower than in typical DNA binding domain mutations. To date, only a few families were detected and diagnosis of carriers remains a challenge. Therefore, the inclusion of additional criteria to detect p.R337H carriers is necessary for the Brazilian population. We assessed the A.C. Camargo Cancer Center Oncogenetics Department database in search of common characteristics associated...

Ecological aspects of Langsdorffia hypogaea (Balanophoraceae) parasitism in the Pantanal wetlands
Provedor de dados: 39
Autores: Lehn,Carlos Rodrigo; Salis,Suzana Maria; Mattos,Patrícia Póvoa.
Most studies on holoparasitic plants have focused on taxonomic or systematic issues. The objective of this study was to examine the ecological aspects of parasitism of Langsdorffia hypogaea (Balanophoraceae) in the Pantanal wetlands. Individuals of L. hypogaea were dug out by hand and the host trees were identified. Eighty-eight percent of host trees exhibited zoochory dispersal syndrome. Protium heptaphyllum and Cordiera sessilis represented 50% of the sampled trees. Both species are evergreen and are preferentially shade-tolerant species growing under the canopy of other trees. Fecal sample of collared peccaries (Pecari tajacu) had seeds from both the host tree (Protium sp.) and the parasite L. hypogaea. We therefore propose the hypothesis that P. tajacu...

¿Ecólogos o Ególogos? Cuando las ideas someten a los datos
Provedor de dados: 67
Autores: Farji-Brener,Alejandro G.
Algunos ecólogos se apasionan tanto por sus ideas que terminan manipulando la información para que los resultados se ajusten a sus predicciones. En este trabajo describo ciertas características de estos investigadores (denominados ególogos porque viven el fracaso de sus hipótesis como una derrota de su ego) y detallo las formas mediante las cuales logran someter a los datos por las ideas. La manipulación de datos raros y la inquisición estadística (torturar los datos hasta que confiesen lo que se desea escuchar) son algunos de los procedimientos más comunes. Para comprender mejor el funcionamiento de la naturaleza, los ecólogos deberíamos ser esclavos de los datos y no de las hipótesis que guiaron su recolección.

Ecólogos y mega-minería, reflexiones sobre por qué y cómo involucrarse en el conflicto minero-ambiental
Provedor de dados: 67
Autores: Donadio,Emiliano.
La minería a gran escala (mega-minería) está recibiendo un impulso importante en Argentina. Esta actividad, cuyo desarrollo requiere el sacrificio de áreas extensas y la utilización de sustancias toxicas, ha generado conflictos socio-ambientales de diversa magnitud, sobre los que diferentes sujetos sociales han hecho pública su postura. Por el contrario, algunas asociaciones profesionales (i.e., Asociación Argentina de Ecología [ASAE] y Sociedad Argentina para el Estudio de los Mamíferos [SAREM]), con participación activa de Ecólogos, se han mantenido al margen de ese debate. En este trabajo sostengo que la ASAE y la SAREM deben involucrarse en el debate minero-ambiental no sólo para cumplir con sus objetivos de creación (contribuir a la protección y...

Ectoparasites of Nasua nasua (Carnivora, Procyonidae) from an urban forest in Southeastern Brazil
Provedor de dados: 45
Autores: Rodrigues,A.F.S.F.; Daemon,E.; Massard,C.L.
Em um fragmento de mata na área urbana de Juiz de Fora (MG) foram capturados 15 quatis com armadilha e ceva, para estudo dos seus ectoparasitos. Outros quatro animais, atropelados no entorno, foram também examinados imediatamente após o atropelamento, e incluídos na análise. Os ectoparasitos foram removidos com a utilização de pinça e pente-fino e acondicionados em etanol 70°GL. Pulgas e piolhos foram clarificados e montados para análise em microscopia. Os ixodídeos foram identificados sob estereoscopia. Não foram encontrados carrapatos adultos. Larvas e ninfas de carrapatos foram encontradas, respectivamente, em 36,8% e 63,1% dos hospedeiros examinados. Ninfas que sofreram muda foram identificadas como Amblyomma cajenennse. A espécie de piolho...

Epiphytes are common in the canopy of temperate and tropical forests, where they substantially contribute to species diversity and to key ecosystem processes. However, little is known about the effects caused by deforestation on this group of species, especially in northeastern Brazil, an area experiencing intense anthropogenic pressure. This study aimed to evaluate the effect of environmental variables on the structure of assemblies of vascular epiphytes in a fragment of open ombrophilous forest, Areia, northeastern Brazil. Sixty 10 × 10 m sampling plots were installed to cover different environments within the fragment. The relationship between environmental variables and species composition was evaluated by means of a generalized linear mixed model. The...

Autores: Strieder Philippssen,Juliana; Soares Angeoletto,Fábio H; Santana,Rosangela G.
The relationship between people and the environment is critical for the development of projects and actions towards the sustainable use of nature resources. This study investigated the relationship between a number of socio-demographic variables and environmental awareness in two cities of southern Brazil (Maringá and Sarandí). We found that levels of education and income were positively associated with environmental awareness. Individuals with higher level of education were 3.2 times more likely to have good environmental awareness than individuals with a lower level. Our results contribute to understand social-ecological interactions of urban citizens from this region and to develop management actions to involve urban residents into environmental...

Simultaneous measurements of EEG-functional magnetic resonance imaging (fMRI) combine the high temporal resolution of EEG with the distinctive spatial resolution of fMRI. The purpose of this EEG-fMRI study was to search for hemodynamic responses (blood oxygen level-dependent - BOLD responses) associated with interictal activity in a case of right mesial temporal lobe epilepsy before and after a successful selective amygdalohippocampectomy. Therefore, the study found the epileptogenic source by this noninvasive imaging technique and compared the results after removing the atrophied hippocampus. Additionally, the present study investigated the effectiveness of two different ways of localizing epileptiform spike sources, i.e., BOLD contrast and independent...

Efecto del ácido indolbutírico (AIB) y de la presencia de hojas en el arraigamiento de estacas de Nothofagus glauca (Phil.) Krasser cosechadas en dos épocas diferentes
Provedor de dados: 67
Autores: Santelices,Rómulo.
Nothofagus glauca (Phil.) Krasser es una especie endémica de la zona mesomórfica de Chile que ha estado sujeta a una intensa presión antrópica. Producto de la fuerte reducción de la superficie de sus bosques la especie se encuentra en un delicado estado de conservación y aún no se conocen bien todos los factores que inciden en su propagación vegetativa. Este trabajo estudió la capacidad de arraigamiento de estacas de tallo colectadas de rebrotes de tocón de árboles de más de veinte años de edad de la zona precordillerana de la provincia de Talca. La cosecha se efectuó en enero de 1996 y noviembre de 1997 y, a través de ensayos independientes entre sí, se analizó el efecto del AIB (0; 0.5; y 1.5%) y de la presencia de hojas (con y sin hojas) en el proceso...

O Brasil apresenta uma diversidade de frutas regionais, principalmente nas regiões Norte e Nordeste. Dentre estas, destaca-se o cupuaçu, que é uma fruta considerada exótica e de grande potencial comercial nos mercados dos estados do Sudeste do Brasil e dos países europeus. A polpa e a semente são importantes para o desenvolvimento de produtos industriais. A polpa tem sido estudada como matéria-prima para néctar; entretanto, é usada em sorvetes, geléias, purês e polpa enlatada. Atualmente, o processo de extração da polpa ainda é feito de maneira empírica, utilizando-se de acessórios como facas, colheres ou tesouras de uso doméstico, devido à forte aderência da mesma ao caroço, causando baixo rendimento no produto final. Com o objetivo de aumentar o...

Efeito da época de aplicação e dosagem do acibenzolar- S-metil na indução de resistência à murcha-de-Verticillium em cacaueiro
Provedor de dados: 102
Autores: Cavalcanti,Leonardo S.; Resende,Mário Lúcio V.
A resistência induzida representa uma medida promissora no manejo de doenças como a murcha-de-Verticillium do cacaueiro (Theobroma cacao), visto que possibilita a exploração de cultivares com boas características agronômicas, porém apresentando suscetibilidade a doenças. Grande avanço nessa área ocorreu com a utilização do éster S-metil do ácido benzo-(1-2-3)-tiadiazole-7-carbotióico (acibenzolar-S-metil, ASM). Contudo, a eficiência desse composto é função, principalmente, da época de aplicação e dosagem utilizada. O presente trabalho teve como objetivo identificar a melhor época de aplicação e dosagem do ASM na interação cacaueiro x Verticillium dahliae. O ASM foi pulverizado via foliar nas concentrações de 20 ou 60 g do ingrediente ativo (i. a.)/100 l de...

Efeitos do Pronaf sobre a pobreza rural no Brasil (2001-2009)
Provedor de dados: 123
Autores: Batista,Henrique Rogê; Neder,Henrique Dantas.
O objetivo deste trabalho é analisar os efeitos do Programa Nacional de Fortalecimento da Agricultura Familiar (Pronaf) sobre a pobreza rural (Índice FGT) no Brasil no período de 2001-2009. Para isto, são geradas estimativas das elasticidades (modelo de painel dinâmico: GMM-Sistema) Pronaf-renda e Pronaf-desigualdade. O trabalho parte do pressuposto que a variável Pronaf não afeta diretamente a pobreza rural e o faz a partir da variação da renda e/ou da variação na desigualdade de renda. A revisão da literatura indica que o aumento na renda per capita ou o decréscimo no Índice de Gini levam a uma redução da pobreza e, além disto, não há um consenso entre o efeito da variação nos repasses do Pronaf sobre a renda, desigualdade e pobreza rural. Os resultados...

Autores: Ventrucci,G.; Mello,M.A.R.; Gomes-Marcondes,M.C.C.
Cancer patients present high mobilization of host protein, with a decrease in lean body mass and body fat depletion occurring in parallel to neoplastic growth. Since leucine is one of the principal amino acids used by skeletal muscle for energy, we investigated the changes in body composition of pregnant tumor-bearing rats after a leucine-supplemented diet. Sixty pregnant Wistar rats divided into six groups were fed a normal protein diet (18%, N) or a leucine-supplemented diet (3% L-leucine, L). The pregnant groups were: control (CN), Walker 256 carcinoma-bearing rats (WN), control rats pair-fed with tumor-bearing rats (pfN), leucine-supplemented (CL), leucine-supplemented tumor-bearing (WL), and leucine-supplemented rats pair-fed with tumor-bearing rats...

The pathogenesis of nonsteroidal anti-inflammatory drug (NSAID) enteropathy is a complex process involving the uncoupling of mitochondrial oxidative phosphorylation and inhibition of cyclooxygenase (COX). Rofecoxib, a selective inhibitor of COX-2, has shown less gastric damage, but the same beneficial effect is not clear in the case of the small bowel. Fifty-seven male Wistar rats (250-350 g) were divided into three groups (N = 19 each) to evaluate the effect of this NSAID on the rat intestine. The groups received 2.5 mg/kg rofecoxib, 7.5 mg/kg indomethacin or water with 5% DMSO (control) given as a single dose by gavage 24 h before the beginning of the experiment. A macroscopic score was used to quantify intestinal lesions and intestinal permeability was...

To extend this research, 7-month-old male EPM-1 mice (N = 30) were divided into two groups: 1) inoculated with tumor cells previously incubated with submaxillary salivary gland extract (SGE) in PBS for 30 min at 37%; 2) inoculated with tumor cells previously incubated with PBS, under the same conditions. Animals were inoculated into the footpad with 40 µl of a suspension containing 4.5 x 107 tumor cells/ml, and footpad thickness was measured daily for 10 days. Sections and smears of tumor cells were prepared from the tumor mass to determine mitosis frequency, percent of...

Rotaviruses are the major cause of viral diarrhea in humans and animals. Actinomycin D (Act D) is an antibiotic that intercalates DNA and therefore inhibits DNA-dependent transcription. The current study was carried out to assess the influence of Act D on the replication of simian rotavirus (SA11) in cell culture. Virus-infected MA-104 cell cultures were studied in the presence of Act D at concentrations of 1.25 and 2.5 µg/ml. Treatment of rotavirus-infected cells with 2.5 µg/ml Act D 48 h post-infection reduced the cytoplasmic metachromasia after staining with acridine orange by 25%. Viral RNA labeled with ³H-uridine in the presence of the drug was separated by polyacrylamide gel electrophoresis. Viral RNA replication was not affected by Act D, but...

Autores: Torres,I.L.S.; Gamaro,G.D.; Silveira-Cucco,S.N.; Michalowski,M.B.; Corrêa,J.B.; Perry,M.L.S; Dalmaz,C.
It has been suggested that glucocorticoids released during stress might impair neuronal function by decreasing glucose uptake by hippocampal neurons. Previous work has demonstrated that glucose uptake is reduced in hippocampal and cerebral cortex slices 24 h after exposure to acute stress, while no effect was observed after repeated stress. Here, we report the effect of acute and repeated restraint stress on glucose oxidation to CO2 in hippocampal and cerebral cortex slices and on plasma glucose and corticosterone levels. Male adult Wistar rats were exposed to restraint 1 h/day for 50 days in the chronic model. In the acute model there was a single exposure. Immediately or 24 h after stress, the animals were sacrificed and the hippocampus and cerebral...

Autores: Onusic,G.M.; Nogueira,R.L.; Pereira,A.M.S.; Viana,M.B.
We investigated the effect of acute oral treatment with a water-alcohol extract of the inflorescence of Erythrina mulungu (EM, Leguminosae-Papilionaceae) (100, 200 and 400 mg/kg) on rats submitted to different anxiety models: the elevated T-maze (for inhibitory avoidance and escape measurements), the light/dark transition, and the cat odor test. These models were selected for their presumed capacity to demonstrate specific subtypes of anxiety disorders as recognized in clinical practice. Treatment with 200 mg/kg EM impaired avoidance latencies (avoidance 1 - 200 mg/kg EM: 18 ± 7 s, control group: 40 ± 9 s; avoidance 2 - 200 mg/kg EM: 15 ± 4 s, control group: 110.33 ± 38 s) in a way similar to the reference drug diazepam (avoidance 1: 3 ± 0.79 s; avoidance...

ABSTRACT This study analyzed the adenosine concentration on quality of ram semen in different refrigerated storage times at 5 °C. The design was in blocks with repeated-measures factorial design. Five levels of adenosine and four refrigeration times were considered as fixed effects and the animal as random effect (block). Ram semen was diluted with Andromed® diluent (control) and increasing adenosine levels (0.5, 0.75, 1, and 1.5%). The samples were taken from refrigeration after 4, 8, 12, and 16 h and evaluated for progressive rectilinear sperm motility, sperm vigor, and membrane integrity (supravital test). Data were subjected to analysis of variance with Tukey's test. The regression analysis was conducted to evaluate behavior of adenosine levels. Factor...

Effect of angiotensin-(1-7) on reperfusion arrhythmias in isolated rat hearts
Provedor de dados: 56
There is increasing evidence that angiotensin-(1-7) (Ang-(1-7)) is an endogenous biologically active component of the renin-angiotensin system (RAS). In the present study, we investigated the effects of Ang-(1-7) on reperfusion arrhythmias in isolated rat hearts. Isolated rat hearts were perfused with two different media, i.e., Krebs-Ringer (2.52 mM CaCl2) and low-Ca2+ Krebs-Ringer (1.12 mM CaCl2). In hearts perfused with Krebs-Ringer, Ang-(1-7) produced a concentration-dependent (27-210 nM) reduction in coronary flow (25% reduction at highest concentration), while only slight and variable changes in contraction force and heart rate were observed. Under the same conditions, angiotensin II (Ang II; 27 and 70 nM) produced a significant reduction in coronary...

Effect of chronic oral administration of a low dose of captopril on sodium appetite of hypothyroid rats: Influence of aldosterone treatment
Provedor de dados: 56
Autores: Ventura,R.R.; Olivares,E.L.; Passos Junior,D.B.; Ramalho,M.J.; Antunes-Rodrigues,J.; Reis,L.C.
Rats rendered hypothyroid by treatment with methimazole develop an exaggerated sodium appetite. We investigated here the capacity of hypothyroid rats (N = 12 for each group) to respond to a low dose of captopril added to the ration, a paradigm which induces an increase in angiotensin II synthesis in cerebral areas that regulate sodium appetite by increasing the availability of circulating angiotensin I. In addition, we determined the influence of aldosterone in hypothyroid rats during the expression of spontaneous sodium appetite and after captopril treatment. Captopril significantly increased (P&lt;0.05) the daily intake of 1.8% NaCl (in ml/100 g body weight) in hypothyroid rats after 36 days of methimazole administration (day 36: 9.2 ± 0.7 vs day 32: 2.8...

Animal models of gentamicin nephrotoxicity present acute tubular necrosis associated with inflammation, which can contribute to intensify the renal damage. Hydrogen sulfide (H2S) is a signaling molecule involved in inflammation. We evaluated the effect of DL-propargylglycine (PAG), an inhibitor of endogenous H2S formation, on the renal damage induced by gentamicin. Male Wistar rats (N = 8) were injected with 40 mg/kg gentamicin (im) twice a day for 9 days, some of them also received PAG (N = 8, 10 mg·kg-1·day-1, ip). Control rats (N = 6) were treated with saline or PAG only (N = 4). Twenty-four-hour urine samples were collected one day after the end of these treatments, blood samples were collected, the animals were sacrificed, and the kidneys were removed...

Effect of epithelial debridement on human cornea proteoglycans
Provedor de dados: 56
Autores: Soriano,E.S.; Campos,M.S.Q.; Aguiar,J.A.K.; Michelacci,Y.M.
Corneal transparency is attributed to the regular spacing and diameter of collagen fibrils, and proteoglycans may play a role in fibrillogenesis and matrix assembly. Corneal scar tissue is opaque and this opacity is explained by decreased ultrastructural order that may be related to proteoglycan composition. Thus, the objectives of the present study were to characterize the proteoglycans synthesized by human corneal explants and to investigate the effect of mechanical epithelial debridement. Human corneas unsuitable for transplants were immersed in F-12 culture medium and maintained under tissue culture conditions. The proteoglycans synthesized in 24 h were labeled metabolically by the addition of 35S-sulfate to the medium. These compounds were extracted...

Effect of FSH and insulin on lipogenesis in cultures of Sertoli cells from immature rats
Provedor de dados: 56
Follicle-stimulating hormone (FSH) and insulin regulate glycide metabolism in Sertoli cells, thus stimulating lactate production. These stimulatory effects of FSH and insulin do not require protein synthesis, suggesting a modulation of enzyme activity and/or regulation of glucose transport. The present investigation was performed to characterize the hormonal control of lipid metabolism in Sertoli cells. The data indicate that FSH and insulin have a regulatory effect on lipid metabolism in Sertoli cells. After 8 h of preincubation with insulin (5 µg/ml), the activity of the enzyme ATP-citrate lyase in cultured Sertoli cells was increased from 0.19 to 0.34 nmol NAD+ formed µg protein-1 min-1. FSH (100 ng/ml) had no effect on this enzyme. Glycerol phosphate...

Effect of gamma irradiation on the behavioral properties of crotoxin
Provedor de dados: 56
Crotoxin has been detoxified with gamma radiation in order to improve crotalic antiserum production. Nevertheless, present knowledge of the biological characteristics of irradiated crotoxin is insufficient to propose it as an immunizing agent. Crotoxin is known to increase the emotional state of rats and to decrease their exploratory behavior (Moreira EG, Nascimento N, Rosa GJM, Rogero JR and Vassilieff VS (1996) Brazilian Journal of Medical and Biological Research, 29: 629-632). Therefore, we decided 1) to evaluate the effects of crotoxin in the social interaction test, which has been widely used for the evaluation of anxiogenic drugs, and 2) to determine if irradiated crotoxin induces behavioral alterations similar to those of crotoxin in the social...

Effect of high temperature on germination of four legumes from a forest-grassland mosaic in Southern Brazil
Provedor de dados: 49
Autores: Silveira,Fernanda Schmidt; Overbeck,Gerhard Ernst.
Passage of a fire can break dormancy of the seeds of many plant species in fire-prone ecosystems. This response to fire is especially well known for the Fabaceae family, but has been poorly studied in Southern Brazil. We collected seeds of four Fabaceae species present in grasslands-forest mosaics of Southern Brazil: Mimosa bimucronata, Desmodium barbatum, Sesbania virgata and Collaea stenophylla. Seeds were exposed to different heat treatments (exposure to 60° and 80 °C for 5 minutes, to 100 °C for 2 minutes, control without heat treatment); not all species were tested in all treatments. After the treatment, the seeds were kept in a germination chamber with a light period of 12/12 hours and temperature of 25 °C. Germinated seeds were counted every 2 days....

Effect of Host Plant on the Fecundity of Spittlebug Deois flavopicta Stal (Homoptera: Cercopidae): Implications on Population Dynamics
Provedor de dados: 82
Autores: SUJJI,E.R.; PIRES,C.S.S.; FONTES,E.M.G.; GARCIA,M.A.
The spittlebug Deois flavopicta Stal (Hom.: Cercopidae) occurs naturally on native grasses in Central Brazil in low population densities. After the introduction of African grasses, mainly of the genus Brachiaria, for cattle raising, D. flavopicta began to produce population outbreaks and became a pest. Two studies were conducted, aiming to estimate the effects of a native and an exotic host plant on the fecundity of this insect. Females of D. flavopicta maintained during the adult stage on Brachiaria ruziziensis produced more eggs and lived longer than those maintained on Axonopus marginatus (a native grass widely distributed in Brazil), independently of the host plant on which the nymphs were reared. Due to the severe damage produced by adult D....

Effect of hydroxyurea on G gamma chain fetal hemoglobin synthesis by sickle-cell disease patients
Provedor de dados: 56
Autores: Teixeira,S.M.; Cortellazzi,L.C.; Grotto,H.Z.W.
Hydroxyurea is used for sickle-cell disease patients in order to increase fetal hemoglobin synthesis and consequently decrease the severity of pain episodes. Fetal hemoglobin, which is formed by gamma-globin chains A and G, is present in a constant composition throughout fetal development: about 75% of Ggamma and 25% of Agamma. In contrast, adult red cells contain about 40% of Ggamma and 60% of Agamma. In the present study, we analyzed the effect of hydroxyurea induction on the gamma chain composition of fetal hemoglobin in 31 sickle-cell disease patients treated with hydroxyurea. The control group was composed of 30 sickle-cell disease patients not treated with hydroxyurea in clinical steady state. The patients were older than 13 years and were not...

Effect of hydroxyurea on the intracellular multiplication of Toxoplasma gondii, Leishmania amazonensis and Trypanosoma cruzi
Provedor de dados: 56
Autores: Melo,E.J.T.; Beiral,H.J.
Toxoplasma gondii, Leishmania amazonensis and Trypanosoma cruzi are obligate intracellular parasites that multiply until lysis of host cells. The present study was undertaken to evaluate the effect of hydroxyurea (an inhibitor of cell division at the G1/S phase) on the multiplication of L. amazonensis, T. gondii, and T. cruzi in infected host cells. Infected cells were treated with hydroxyurea (4 mM) for 48 h. Hydroxyurea arrested intracellular multiplication of all infective forms of the parasites tested. In treated cultures, the percent of infected host cells decreased (50-97%) and most intracellular parasites were eliminated. Ultrastructural observations showed no morphologic change in host cells while intracellular parasites presented drastic...

Glutamate receptors have been implicated in memory formation. The aim of the present study was to determine the effect of inhibitory avoidance training on specific [3H]-glutamate binding to membranes obtained from the hippocampus or parietal cortex of rats. Adult male Wistar rats were trained (0.5-mA footshock) in a step-down inhibitory avoidance task and were sacrificed 0, 5, 15 or 60 min after training. Hippocampus and parietal cortex were dissected and membranes were prepared and incubated with 350 nM [3H]-glutamate (N = 4-6 per group). Inhibitory avoidance training induced a 29% increase in glutamate binding in hippocampal membranes obtained from rats sacrificed at 5 min (P&amp;lt;0.01), but not at 0, 15, or 60 min after training, and did not affect...

Effect of intracerebroventricularly injected insulin on urinary sodium excretion by cerebroventricular streptozotocin-treated rats
Provedor de dados: 56
Autores: Macedo,R.F.; Furlan,F.C.; Marshall,P.S.; Michelotto,J.B.; Gontijo,J.A.R.
Recent evidence suggests that insulin may influence many brain functions. It is known that intracerebroventricular (icv) injection of nondiabetogenic doses of streptozotocin (STZ) can damage insulin receptor signal transduction. In the present study, we examined the functional damage to the brain insulin receptors on central mechanisms regulating glomerular filtration rate and urinary sodium excretion, over four periods of 30 min, in response to 3 µl insulin or 0.15 NaCl (vehicle) injected icv in STZ-treated freely moving Wistar-Hannover rats (250-300 g). The icv cannula site was visually confirmed by 2% Evans blue infusion. Centrally administered insulin (42.0 ng/µl) increased the urinary output of sodium (from 855.6 ± 85.1 to 2055 ± 310.6 delta%/min; N =...

Effect of metabolic acidosis on renal tubular sodium handling in rats as determined by lithium clearance
Provedor de dados: 56
Autores: Menegon,L.F.; Figueiredo,J.F.; Gontijo,J.A.R.
Systemic metabolic acidosis is known to cause a decrease in salt and water reabsorption by the kidney. We have used renal lithium clearance to investigate the effect of chronic, NH4Cl-induced metabolic acidosis on the renal handling of Na+ in male Wistar-Hannover rats (200-250 g). Chronic acidosis (pH 7.16 ± 0.13) caused a sustained increase in renal fractional Na+ excretion (267.9 ± 36.4%), accompanied by an increase in fractional proximal (113.3 ± 3.6%) and post-proximal (179.7 ± 20.2%) Na+ and urinary K+ (163.4 ± 5.6%) excretion when compared to control and pair-fed rats. These differences occurred in spite of an unchanged creatinine clearance and Na+ filtered load. A lower final body weight was observed in the acidotic (232 ± 4.6 g) and pair-fed (225 ±...

The aim of the present study was to assess the reproductive parameters of obese Wistar rats and to determine the frequency of their obese adult offspring. Neonatal rats were divided into two groups: F1 generation, induced to obesity by monosodium glutamate (MSG; F1MSG, N = 30), and rats given saline (F1CON, N = 13). At 90 days of age all animals were mated, producing the F2 offspring (F2CON, N = 28; F2MSG, N = 15). Reproductive parameters (fertility, pregnancy, and delivery indexes) were evaluated in F1 rats. F2 newborns were weighed, and the obesity parameter for F1 and F2 generations was determined from months 5 to 7 of life. At month 7, periovarian fat was weighed and no differences were found. Mean newborn weight also did not differ. The F1 and F2MSG...

Autores: Calil-Elias,S.; Thattassery,E.; Martinez,A.M.B.; Melo,P.A.
The effect of dose and volume of a perimuscular injection of Bothrops jararacussu venom on myonecrosis of skeletal muscle was studied in mice. An increase of the venom dose (0.25 to 2.0 µg/g) at a given volume (50 µl) resulted in an increase in plasma creatine kinase (CK) levels 2 h after injection. Plasma CK activity increased from the basal level of 129.27 ± 11.83 (N = 20) to 2392.80 ± 709.43 IU/l (N = 4) for the 1.0 µg/g dose. Histological analysis of extensor digitorum longus muscle 4 h after injection showed lesion of peripheral muscle fibers, disorganization of the bundles or the complete degeneration of muscle fibers. These lesions were more extensive when higher doses were injected. Furthermore, an increase in volume (12.5 to 100 µl) by dilution of...

Potassium participates in the essential processes in plant physiology, however, the effects of K sources on plant metabolism have been little studied. Also, in certain cases, K sources and concentrations may cause undesirable effects, e.g., soil salinization. The objective was to evaluate the effect of K sources and levels on the enzyme activity of the antioxidant system and protein content in eggplant (Solanum melongena L.) leaves and to determine the most suitable K sources for these physiological characteristics. The experiment was conducted in randomized blocks, in a 2 × 4 factorial design, consisting of two K sources (KCl and K2SO4) and rates (250, 500, 750, and 1000 kg ha-1 K2O), with four replications.

Effect of prostaglandin A1 in the induction of stress proteins in Aedes albopictus cells
Provedor de dados: 56
Autores: Barbosa,J.A.; Rebello,M.A.
Prostaglandins are natural fatty acid derivatives with diverse physiological effects, including immune function and the control of cell growth. While the action of prostaglandins in the induction of stress proteins in vertebrate cells is well documented, their functions in invertebrate cells have been poorly investigated. The purpose of the present study was to investigate the effect of prostaglandin A1 (PGA1; 0.25, 1.25 and 12.5 µg/ml) on protein synthesis during the growth of Aedes albopictus cells. We found that PGA1 stimulates the synthesis of several polypeptides with molecular masses of 87, 80, 70, 57, 29, 27 and 23 kDa in Aedes albopictus cells. When the proteins induced by PGA1 and those induced by heat treatment were compared by polyacrylamide gel...

Provedor de dados: 56
Autores: Torres,I.L.S.; Vasconcellos,A.P.; Silveira Cucco,S.N.; Dalmaz,C.
There is extensive evidence that acute stress induces an analgesic response in rats. On the other hand, repeatedly stressed animals may present the opposite effect, i.e., hyperalgesia. Furthermore, exposure to novelty is known to induce antinociception. The effects of repeated restraint stress on nociception after exposure to novelty, as measured by the tail-flick latency (TFL), were studied in adult male rats. The animals were stressed by restraint 1 h daily, 5 days a week for 40 days. The control group was not submitted to restraint. Nociception was assessed with a tail-flick apparatus. After being familiarized with the TFL apparatus, each group was subdivided into two other groups, i.e., with or without novelty. Animals were subjected to the TFL...

Autores: Bassani,J.W.M.; Godoy,C.M.G.; Bassani,R.A.
Evidence has indicated that the sarcoplasmic reticulum (SR) might be involved in the generation of spontaneous electrical activity in atrial pacemaker cells. We report the effect of disabling the SR with ryanodine (0.1 µM) on the sinus node recovery time (SNRT) measured in isolated right atria from 4-6-month-old male Wistar rats. Electrogram and isometric force were recorded at 36.5oC. Two methods for sinus node resetting were used: a) pulse: a single stimulus pulse interpolated at coupling intervals of 50, 65 or 80% of the regular spontaneous cycle length (RCL), and b) train: a 2-min train of pulses at intervals of 50, 65 or 80% of RCL. Corrected SNRT (cSNRT) was calculated as the difference between SNRT (first spontaneous cycle length after stimulation...

Autores: Itoyama,Mary Massumi; Bicudo,Hermione Elly Melara de Campos.
The present study analyzed the number of progeny of stannous chloride- and/or caffeine-treated Drosophila prosaltans. A significant decreasing effect was observed in every case when compared to the control, except for the smallest stannous chloride dose used. Combinations of both substances using two different stannous chloride doses did not differ significantly from each other but number of progeny decreased 15% with the higher concentration combination when compared with caffeine-treated flies. The present results and data in the literature indicate that the effects of continuous ingestion of stannous chloride should be studied.

The effects of strenuous exercise before and during pregnancy on the renal function and morphological alterations of the progeny were determined in a study on female Wistar rats. This research was done based on a previous study carried out in our laboratory, which showed morphological alterations in rats submitted to this kind of exercise. As the form is related to the function, the physiological relevance of submitting a pregnant female to a high-intensity exercise training regimen could be explained by the fact that morphological alterations can influence kidney function. The animals were assigned to one of two groups: control animals that did not exercise during pregnancy and trained animals that swam for 120 min 5 days a week for 8 weeks before...

Provedor de dados: 56
Autores: Arruda,E.Z.; Silva,N.M.V.; Moraes,R.A.M.; Melo,P.A.
We investigated the protective effect of suramin, an enzyme inhibitor and an uncoupler of G protein from receptors, on the myotoxic activity in mice of different crotalid snake venoms (A.c. laticinctus, C.v. viridis, C.d. terrificus, B. jararacussu, B. moojeni, B. alternatus, B. jararaca, L. muta). Myotoxicity was evaluated in vivo by injecting im the venoms (0.5 or 1.0 mg/kg) dissolved in physiological saline solution (0.1 ml) and measuring plasma creatine kinase (CK) activity. Two experimental approaches were used in mice (N = 5 for each group). In protocol A, 1 mg of each venom was incubated with 1.0 mg suramin (15 min, 37ºC, in vitro), and then injected im into the mice at a dose of 1.0 mg/kg (in vivo). In protocol B, venoms, 1.0 mg/kg, were injected...

Effect of temperature and substrate moisture on group survival of Constrictotermes sp. (Isoptera: Termitidae) under laboratory conditions
Provedor de dados: 92
Autores: Ferreira,Dinamarta V.; Cruz,Joseane S.; Sacramento,Jailton J.M.; Rocha,Marcos Leandro C.; Cristaldo,Paulo F.; Araújo,Ana Paula A.
ABSTRACT Laboratory bioassays should be performed under appropriate conditions that minimize stress and promote greater longevity to tested animals. For social insects, for instance, the stress triggered by removal individuals from nests may result in changes in their survival and behavior. Here we analyzed the effects of variations of different combinations of temperature and substrate moisture (mL of water/g of nest substrate) on group survival of Constrictotermes sp. (Termitidae: Nasutitermitinae). In general, lower substrate moisture resulted in faster mortality. On the other hand, groups survival longer at a temperature of 26 ºC and under higher substrate moisture (2–3 mL/7 g of nest substrate). The result of this study may contribute to the...

Effect of the aerobic capacity on the validity of the anaerobic threshold for determination of the maximal lactate steady state in cycling
Provedor de dados: 56
Autores: Denadai,B.S.; Figueira,T.R.; Favaro,O.R.P.; Gonçalves,M.
The maximal lactate steady state (MLSS) is the highest blood lactate concentration that can be identified as maintaining a steady state during a prolonged submaximal constant workload. The objective of the present study was to analyze the influence of the aerobic capacity on the validity of anaerobic threshold (AT) to estimate the exercise intensity at MLSS (MLSS intensity) during cycling. Ten untrained males (UC) and 9 male endurance cyclists (EC) matched for age, weight and height performed one incremental maximal load test to determine AT and two to four 30-min constant submaximal load tests on a mechanically braked cycle ergometer to determine MLSS and MLSS intensity. AT was determined as the intensity corresponding to 3.5 mM blood lactate. MLSS...

Effect of the consumption of tomato paste on plasma prostate-specific antigen levels in patients with benign prostate hyperplasia
Provedor de dados: 56
Autores: Edinger,M.S.; Koff,W.J.
The consumption of tomatoes and tomato products has been associated with a reduced risk of prostate cancer. We observed a decrease of 10.77% in prostate-specific antigen (PSA) levels in patients with benign prostate hyperplasia who were submitted to daily ingestion of tomato paste. This was an experimental rather than a controlled study with a sample of 43 men ranging in age from 45 to 75 years, all with histological diagnoses of benign prostate hyperplasia and plasma PSA levels of 4-10 ng/mL. All patients received 50 g of tomato paste once a day for 10 consecutive weeks and PSA levels were analyzed before, during and after the consumption of tomato paste. ANOVA for repeated measures was used to compare PSA levels before, during and after the consumption...

Autores: Castro,L.; Varjão,B.; Silva,I.; Duque,B.; Batista,A.; Santana,R.; Luz,P.; Rocha Junior,M.A.; Fregoneze,J.B.; De Castro-e-Silva,E.
We demonstrate here that acute third ventricle injections of GR 113808, a highly selective 5-HT4 antagonist, decrease water intake induced by a previous salt load while potentiating drinking elicited by hypovolemia induced by previous subcutaneous administration of polyethylene glycol in male Wistar rats (200 ± 20 g). At the dose of 160 nmol/rat, third ventricle injections of GR 113808 induced a significant reduction of water intake in salt-loaded animals after 120 min as compared to salt-loaded animals receiving third ventricle injections of saline (salt load + GR = 3.44 ± 0.41 ml, N = 12; salt load + saline = 5.74 ± 0.40 ml, N = 9). At the dose of 80 nmol/rat, GR 113808 significantly enhanced water intake in hypovolemic animals after 120 min as compared...

ABSTRACT The objective of this study was to evaluate the effect of temperature-humidity index (THI) on the milk coagulation properties of Holstein-Friesian dairy cattle from northeast part of Italy. A total of 592 individual milk samples from six dairy herds were evaluated. The milk coagulation properties traits analysed were milk rennet coagulation time and curd firmness, as well as the fat, protein, and casein contents, pH, milk aptitude to coagulate (IAC), and the somatic cell count. The THI was determined during the periods of sample collection. The THI results showed that values of up to 75 did not significantly change the IAC values; however, when the THI values were above 75, the IAC decreased significantly. The control of THI can be used to...

Effect of urea on biomimetic aggregates
Provedor de dados: 56
The effect of urea on biomimetic aggregates (aqueous and reversed micelles, vesicles and monolayers) was investigated to obtain insights into the effect of the denaturant on structured macromolecules. Direct evidence obtained from light scattering (static and dynamic), monolayer maximum isothermal compression and ionic conductivity measurements, together with indirect evidence from fluorescence photodissociation, fluorescence suppression, and thermal reactions, strongly indicates the direct interaction mechanism of urea with the aggregates. Preferential solvation of the surfactant headgroups by urea results in an increase in the monomer dissociation degree (when applied), which leads to an increase in the area per headgroup and also in the loss of...

Effect of ventilation on systemic blood flow evaluated by echodopplercardiography
Provedor de dados: 56
Systemic blood flow (Q) was measured by echodopplercardiography in 5 normal young adult males during apnea, eupnea and tachypnea. Measurements were made in a recumbent posture at 3-min intervals. Tachypnea was attained by doubling the respiratory frequency at eupnea at a constant tidal volume. An open glottis was maintained during apnea at the resting respiratory level. The Q values were positively correlated with the respiratory frequency, decreasing from eupnea to apnea and increasing from eupnea to tachypnea (P&amp;lt;0.05). These data demonstrate that echodopplercardiography, a better qualified tool for this purpose, confirms the positive and progressive effects of ventilation on systemic blood flow, as suggested by previous studies based on diverse...

The aim of this work was to evaluate the ash toxicity from the Puyehue-Cordón Caulle volcanic complex on the survival of two Orthopteran species: the grasshoper Dichroplus vittigerum and the green locust Brugilis sp. Two grain size were used to evaluate the effect of volcanic eruption on these insects. Chemical analyses from this eruption proved that the ashes were very abrasive and predominantly composed of silica shards (SiO2) and aluminia (Al2O3), two substances with insecticidal properties. In northern Patagonia, both orthopteran species are polyphagous chewers on grasses and dicots. The laboratory data showed that sustained exposure to volcanic ash induced mortality in adult grasshoppers. Survival of D. vittigerum significantly decreased once exposed...

In tumor-bearing rats, most of the serum amino acids are used for synthesis and oxidation processes by the neoplastic tissue. In the present study, the effect of Walker 256 carcinoma growth on the intestinal absorption of leucine, methionine and glucose was investigated in newly weaned and mature rats. Food intake and carcass weight were decreased in newly weaned (NT) and mature (MT) rats bearing Walker 256 tumor in comparison with control animals (NC and MC). The tumor/carcass weight ratio was higher in NT than in MT rats, whereas nitrogen balance was significantly decreased in both as compared to control animals. Glucose absorption was significantly reduced in MT rats (MT = 47.3 ± 4.9 vs MC = 99.8 ± 5.3 nmol min-1 cm-1, Kruskal-Wallis test,...

Controversy still exists concerning the potential ergogenic benefit of caffeine (CAF) for exercise performance. The purpose of this study was to compare the effects of CAF ingestion on endurance performance during exercise on a bicycle ergometer at two different intensities, i.e., approximately 10% below and 10% above the anaerobic threshold (AT). Eight untrained males, non-regular consumers of CAF, participated in this study. AT, defined as the intensity (watts) corresponding to a lactate concentration of 4 mM, was determined during an incremental exercise test from rest to exhaustion on an electrically braked cycle ergometer. On the basis of these measurements, the subjects were asked to cycle until exhaustion at two different intensities, i.e.,...

Effects of chronic corticosterone and imipramine administration on panic and anxiety-related responses
Provedor de dados: 56
Autores: Diniz,L.; dos Reis,B.B.; de Castro,G.M.; Medalha,C.C.; Viana,M.B.
It is known that chronic high levels of corticosterone (CORT) enhance aversive responses such as avoidance and contextual freezing. In contrast, chronic CORT does not alter defensive behavior induced by the exposure to a predator odor. Since different defense-related responses have been associated with specific anxiety disorders found in clinical settings, the observation that chronic CORT alters some defensive behaviors but not others might be relevant to the understanding of the neurobiology of anxiety. In the present study, we investigated the effects of chronic CORT administration (through surgical implantation of a 21-day release 200 mg pellet) on avoidance acquisition and escape expression by male Wistar rats (200 g in weight at the beginning of the...

ABSTRACT Leaf-cutting ants live symbiotically with a fungus that they cultivate on the plant leaves that they cut. The innumerous studies on the plant selection mechanism used by leaf-cutting ants show the researchers’ interest in this issue. Many classical studies propose that plants are selected according to the fungus garden nutritional needs and the absence of potentially harmful substances. This hypothesis is corroborated by behavioral experiments using cycloheximide (fungicide) with citric pulp or forage plants greatly accepted by leaf-cutting ants. According to this hypothesis, under the action of a fungicide, the fungus emits an allomone that informs worker ants that some food is inadequate to its growth. Although some authors state that the...

Normal aging is accompanied by renal functional and morphological deterioration and dietetic manipulation has been used to delay this age-related decline. We examined the effects of chronic administration of diets containing 5% lipid-enriched diet (LD, w/w) on renal function of rats at different ages. Three types of LD were tested: canola oil, fish oil and butter. Mean systemic tail-cuff blood pressure and glycemia remained within the normal range whatever the age and the diet of the animals. Proteinuria began to rise from the 8th month in the groups ingesting LD, while in the control group it increased significantly (above 10 mg/24 h) only after the 10th month. With age, a significant and progressive decline in glomerular filtration rate (GFR) and renal...

Autores: Machado,E.F.A.; Normand,A.C.R.; Nunes,L.A.S.; Brenzikofer,R.; Macedo,D.V.
Anesthetics can affect the structure and biological function of tissues and systems differentially. The aim of the present study was to compare three injectable anesthetics generally used in experiments with animals in terms of the degree of hemolysis and glycogenolysis occurring after profound anesthesia. Twenty-four male Wistar rats (330-440 g) were divided into three groups (N = 8): chloral hydrate (CH), ketamine + xylazine (KX), Zoletil 50® (zolazepam and tiletamine) + xylazine (ZTX). After deep anesthesia, total blood was collected. The liver and white (WG) and red gastrocnemius (RG) muscles were also immediately removed. The degree of serum hemolysis was quantified on the basis of hemoglobin concentration (g/L). Hepatic and muscular glycogen...

Effects of double-stranded RNA on virulence of Paecilomyces fumosoroseus (Deuteromycotina: Hyphomycetes) against the silverleaf whitefly, Bemisia tabaci strain B (Homoptera: Aleyrodidae)
Provedor de dados: 74
Autores: Azevedo,Andréia Cristiane Souza; Sosa-Gómez,Daniel Ricardo; Faria,Marcos Rodrigues; Fungaro,Maria Helena Pelegrinelli.
Bands of double-stranded RNA (dsRNA) were detected in three out of twelve isolates of Paecilomyces fumosoroseus. Identity of these bands was confirmed by RNAse, DNAse and S1 nuclease treatments. The cure of dsRNA for one isolate (P92) was successfully carried out for a single conidium subculture. Isogenic strains, with or without dsRNA, were submitted to virulence tests against the whitefly Bemisia tabaci strain B. In contrast to findings for some phytopathogenic fungi, these dsRNA fragments did not cause hypovirulence in P. fumosoroseus.

Effects of emotional reactivity on inhibitory avoidance in the elevated T-maze
Provedor de dados: 56
Autores: Conde,C.; Costa,V.; Tomaz,C.
The possibility of the presence of inter-individual emotional differences and the memory performance of rats was examined in the elevated T-maze. Two kinds of aversively motivated behaviors, inhibitory avoidance and escape learning, were measured. Based on the number of trials to achieve a learning criterion, rats were divided into two subgroups with either low or high avoidance reactivity (LAR or HAR, respectively). Retention test avoidance latencies showed that HAR animals had better avoidance memory (Mann-Whitney rank sum test, P = 0.0035). No such differences were found for the escape component of this test. These data suggest that individual emotional differences affect inhibitory avoidance performance, which may help to explain the dispersion of the...

Effects of entorhinal cortex lesions on memory in different tasks
Provedor de dados: 56
Lesions of the entorhinal cortex produce retrograde memory impairment in both animals and humans. Here we report the effects of bilateral entorhinal cortex lesions caused by the stereotaxic infusion of N-methyl-D-aspartate (NMDA) in rats at two different moments, before or after the training session, on memory of different tasks: two-way shuttle avoidance, inhibitory avoidance and habituation to an open field. Pre- or post-training entorhinal cortex lesions caused an impairment of performance in the shuttle avoidance task, which agrees with the previously described role of this area in the processing of memories acquired in successive sessions. In the inhibitory avoidance task, only the post-training lesions had an effect (amnesia). No effect was observed...

Estragole, a relatively nontoxic terpenoid ether, is an important constituent of many essential oils with widespread applications in folk medicine and aromatherapy and known to have potent local anesthetic activity. We investigated the effects of estragole on the compound action potential (CAP) of the rat sciatic nerve. The experiments were carried out on sciatic nerves dissected from Wistar rats. Nerves, mounted in a moist chamber, were stimulated at a frequency of 0.2 Hz, with electric pulses of 50-100-µs duration at 10-20 V, and evoked CAP were monitored on an oscilloscope and recorded on a computer. CAP control parameters were: peak-to-peak amplitude (PPA), 9.9 ± 0.55 mV (N = 15), conduction velocity, 92.2 ± 4.36 m/s (N = 15), chronaxy, 45.6 ± 3.74 µs...

Effects of ethanol intake on retinol concentration in the milk of lactating rats
Provedor de dados: 56
Autores: Albuquerque,K.T.; Ramalho,R.A.; Soares,A.G.; Tavares-do-Carmo,M.G.
The effect of the consumption of ethanol (5%) on retinol concentration in milk was studied in the rat on day 12 after delivery, together with the evolution of dam body weight and pup growth rate. Female Wistar rats receiving alcohol (5%) in drinking water during lactation (N = 7) were compared to normal controls fed ad libitum (N = 6). The mean maternal alcohol intake was 3.96 ± 0.23 g/kg body weight per day. To determine retinol levels in milk we used the Bessey and Lowry method, modified by Araújo and Flores ((1978) Clinical Chemistry, 24: 386-392). The pups were separated from dams for a 2-4-h period, after which the dams were injected intraperitoneally with anesthetic and oxytocin. The concentration of retinol in milk was 162.88 ± 10.60 µg/dl in the...

ABSTRACT This study was carried out to to evaluate how feed restriction and different forage:concentrate ratios affect digestibility, methane emission (using the SF6 technique), and energy utilization of Anglo-Nubian goats. Fifteen (15) dry and non-pregnant Anglo Nubian goats, averaging 30±2.9 kg body weight, were used. The experiment was divided into two trials, the first of which was designed to study the effects of feed restriction (0% or ad libitum; 15% of feed restriction or equivalent to 85% of ad libitum intake; and 40% of feed restriction or equivalent to 60% of ad libitum intake) and the second, to study the effects of forage:concentrate (F:C) ratios (75:25, 54:46, and 25:75) in the diet. The sulfur hexafluoride (SF6) tracer gas method was used to...

Effects of formaldehyde on the frog's mucociliary epithelium as a surrogate to evaluate air pollution effects on the respiratory epithelium
Provedor de dados: 56
Autores: Fló-Neyret,C.; Lorenzi-Filho,G.; Macchione,M.; Garcia,M.L.B.; Saldiva,P.H.N.
The increasing use of alcohol as an alternative fuel to gasoline or diesel can increase emission of formaldehyde, an organic gas that is irritant to the mucous membranes. The respiratory system is the major target of air pollutants and its major defense mechanism depends on the continuous activity of the cilia and the resulting constant transportation of mucous secretion. The present study was designed to evaluate the effects of formaldehyde on the ciliated epithelium through a relative large dose range around the threshold limit value adopted by the Brazilian legislation, namely 1.6 ppm (1.25 to 5 ppm). For this purpose, the isolated frog palate preparation was used as the target of toxic injury. Four groups of frog palates were exposed to diluted Ringer...

Effects of L-arginine on the diaphragm muscle twitches elicited at different frequencies of nerve stimulation
Provedor de dados: 56
Autores: Queiroz,R.N.; Alves-Do-Prado,Wilson.
In rats, the nitric oxide (NO)-synthase pathway is present in skeletal muscle, vascular smooth muscle, and motor nerve terminals. Effects of NO were previously studied in rat neuromuscular preparations receiving low (0.2 Hz) or high (200 Hz) frequencies of stimulation. The latter frequency has always induced tetanic fade. However, in these previous studies we did not determine whether NO facilitates or impairs the neuromuscular transmission in preparations indirectly stimulated at frequencies which facilitate neuromuscular transmission. Thus, the present study was carried out to examine the effects of NO in rat neuromuscular preparations indirectly stimulated at 5 and 50 Hz. The amplitude of muscular contraction observed at the end (B) of a 10-s...

Lead has been shown to produce cognitive and motor deficits in young rats that could be mediated, at least in part, by inhibition of the zinc-containing heme biosynthetic enzyme delta-aminolevulinate dehydratase (ALA-D). In the present study we investigated the effects of lead and/or zinc treatment during the second stage of rapid postnatal brain development on brain, kidney and blood ALA-D specific activity, as well as the negative geotaxis behavior of rats. Eight-day-old Wistar rats were injected intraperitoneally with saline, lead acetate (8 mg/kg) and/or zinc chloride (2 mg/kg) daily for five consecutive days. Twenty-four hours after treatment, ALA-D activity was determined in the absence and presence of DL-dithiothreitol (DTT). The negative geotaxis...

Effects of naltrexone and cross-tolerance to morphine in a learned helplessness paradigm
Provedor de dados: 56
Opiates have been implicated in learned helplessness (LH), a phenomenon known to be related to opiate stress-induced analgesia (SIA). In the present study, we investigated the role of opiates in the induction of LH and SIA under different conditions. Adult female Wistar rats were trained either by receiving 60 inescapable 1-mA footshocks (IS group, N = 114) or by confinement in the shock box (control or NS group, N = 92). The pain threshold of some of the animals was immediately evaluated in a tail-flick test while the rest were used 24 h later in a shuttle box experiment to examine their escape performance. The opiate antagonist naltrexone (0 or 8 mg/kg, ip) and the previous induction of cross-tolerance to morphine by the chronic administration of...

Effects of ouabain on vascular reactivity
Provedor de dados: 56
Ouabain is an endogenous substance occurring in the plasma in the nanomolar range, that has been proposed to increase vascular resistance and induce hypertension. This substance acts on the&lt;FONT FACE="Symbol"&gt; a&lt;/font&gt;-subunit of Na+,K+-ATPase inhibiting the Na+-pump activity. In the vascular smooth muscle this effect leads to intracellular Na+ accumulation that reduces the activity of the Na+/Ca2+ exchanger and to an increased vascular tone. It was also suggested that circulating ouabain, even in the nanomolar range, sensitizes the vascular smooth muscle to vasopressor substances. We tested the latter hypothesis by studying the effects of ouabain in the micromolar and nanomolar range on phenylephrine (PE)-evoked pressor responses. The...

Autores: Kuriyama,S.N.; De-Oliveira,A.C.A.X.; Fidalgo-Neto,A.A.; Paumgartten,F.J.R.
Xenobiotic metabolism is influenced by a variety of physiological and environmental factors including pregnancy and nutritional status of the individual. Pregnancy has generally been reported to cause a depression of hepatic monooxygenase activities. Low-protein diets and protein-energy malnutrition have also been associated with a reduced activity of monooxygenases in nonpregnant animals. We investigated the combined effects of pregnancy and protein-energy malnutrition on liver monooxygenase O-dealkylation activity. On pregnancy day 0 rats were assigned at random to a group fed ad libitum (well-nourished, WN) or to a malnourished group (MN) which received half of the WN food intake (12 g/day). WN and MN rats were killed on days 0 (nonpregnant), 11 or 20...

Autores: Cavalcanti,Liana Monique Paiva; Paiva,Luciana Vieira de; França,Leonardo Fernandes.
ABSTRACT In semi-arid ecosystems, birds commonly use rainfall as a reliable environmental cue to adjust the timing and strength of their reproductive activity. Here we evaluate this hypothesis for a community of birds in the Caatinga (the semi-arid region of northeastern Brazil), using brood patch information and nest abundance. Sampling occurred every 14 days between September 2012 and August 2013 (brood patch), and every three or four days during the reproductive period (nests). Abundance of brood patches and nests were correlated, and all brood patches were recorded between March and July (4.5 to 5.0 months). We recorded three peaks of brood patch abundance: the first 28 days after the first rains, the second 14 days after the second rainfall peak, and...

Effects of reversible inactivation of the dorsomedial hypothalamus on panic- and anxiety-related responses in rats
Provedor de dados: 56
Autores: Nascimento,J.O.G.; Zangrossi Jr.,H.; Viana,M.B.
The medial hypothalamus is part of a neurobiological substrate controlling defensive behavior. It has been shown that a hypothalamic nucleus, the dorsomedial hypothalamus (DMH), is involved in the regulation of escape, a defensive behavior related to panic attacks. The role played by the DMH in the organization of conditioned fear responses, however, is less clear. In the present study, we investigated the effects of reversible inactivation of the DMH with the GABA A agonist muscimol on inhibitory avoidance acquisition and escape expression by male Wistar rats (approximately 280 g in weight) tested in the elevated T-maze (ETM). In the ETM, inhibitory avoidance, a conditioned defensive response, has been associated with generalized anxiety disorder. Results...

Autores: Torres,P.M.M.; Guilarducci,C.V.V.; Araujo,E.G.
Schwann cells produce and release trophic factors that induce the regeneration and survival of neurons following lesions in the peripheral nerves. In the present study we examined the in vitro ability of developing rat retinal cells to respond to factors released from fragments of sciatic nerve. Treatment of neonatal rat retinal cells with sciatic-conditioned medium (SCM) for 48 h induced an increase of 92.5 ± 8.8% (N = 7 for each group) in the amount of total protein. SCM increased cell adhesion, neuronal survival and glial cell proliferation as evaluated by morphological criteria. This effect was completely blocked by 2.5 µM chelerythrine chloride, an inhibitor of protein kinase C (PKC). These data indicate that PKC activation is involved in the effect...

The medial septum participates in the modulation of exploratory behavior triggered by novelty. Also, selective lesions of the cholinergic component of the septohippocampal system alter the habituation of rats to an elevated plus-maze without modifying anxiety indices. We investigated the effects of the intraseptal injection of the cholinergic immunotoxin 192 IgG-saporin (SAP) on the behavior of rats in an open-field. Thirty-nine male Wistar rats (weight: 194-230 g) were divided into three groups, non-injected controls and rats injected with either saline (0.5 µl) or SAP (237.5 ng/0.5 µl).

Autores: Costa,R.A.; Ruiz-de-Souza,V.; Azevedo Jr.,G.M.; Vaz,N.M.; Carvalho,C.R.
Round holes in the ears of MRL mice tend to close with characteristics of regeneration believed to be absent in other mouse strains (e.g., C57BL/6). We evaluated the kinetics and the histopathology of ear wound closure in young (8 weeks old) C57BL/6 and BALB/c mice. We also used middle-aged (40 weeks old) C57BL/6 mice to evaluate the influence of aging on this process. A circular through-and-through hole was made in the ear, photographs were taken at different times after injury and wound area was measured with digital analysis software. The percentages of closed area measured on day 100 were: 23.57 ± 8.66% for young BALB/c mice, 56.47 ± 7.39% for young C57BL/6 mice, and 75.31 ± 23.65% for middle-aged C57BL/6 mice. Mice were sacrificed on days 1, 3, 5, 25,...

Lime application recommendations for amendment of soil acidity in sugarcane were developed with a burnt cane harvesting system in mind. Sugarcane is now harvested in most areas without burning, and lime application for amendment of soil acidity in this system in which the sugarcane crop residue remains on the ground has been carried out without a scientific basis. The aim of this study was to evaluate the changes in soil acidity and stalk and sugar yield with different rates of surface application of calcium, magnesium silicate, and gypsum in ratoon cane. The experiment was performed after the 3rd harvest of the variety SP 81-3250 in a commercial green sugarcane plantation of the São Luiz Sugar Mill (47º 25' 33" W; 21º 59' 46" S), located in Pirassununga,...

Effects of systemic administration of ciliary neurotrophic factor on Bax and Bcl-2 proteins in the lumbar spinal cord of neonatal rats after sciatic nerve transection
Provedor de dados: 56
Autores: Rezende,A.C.S.; Vieira,A.S.; Rogério,F.; Rezende,L.F.; Boschero,A.C.; Negro,A.; Langone,F.
Ciliary neurotrophic factor (CNTF) is a cytokine that plays a neuroprotective role in relation to axotomized motoneurons. We determined the effect of daily subcutaneous doses of CNTF (1.2 µg/g for 5 days; N = 13) or PBS (N = 13) on the levels of mRNA for Bcl-2 and Bax, as well as the expression and inter-association of Bcl-2 and Bax proteins, and the survival of motoneurons in the spinal cord lumbar enlargement of 2-day-old Wistar rats after sciatic nerve transection. Five days after transection, the effects were evaluated on histological and molecular levels using Nissl staining, immunoprecipitation, Western blot analysis, and reverse transcriptase-polymerase chain reaction. The motoneuron survival ratio, defined as the ratio between the number of...

Effects of terpineol on the compound action potential of the rat sciatic nerve
Provedor de dados: 56
Autores: Moreira,M.R.; Cruz,G.M.P.; Lopes,M.S.; Albuquerque,A.A.C.; Leal-Cardoso,J.H.
Terpineol, a volatile terpenoid alcohol of low toxicity, is widely used in the perfumery industry. It is an important chemical constituent of the essential oil of many plants with widespread applications in folk medicine and in aromatherapy. The effects of terpineol on the compound action potential (CAP) of rat sciatic nerve were studied. Terpineol induced a dose-dependent blockade of the CAP. At 100 µM, terpineol had no demonstrable effect. At 300 µM terpineol, peak-to-peak amplitude and conduction velocity of CAP were significantly reduced at the end of 180-min exposure of the nerve to the drug, from 3.28 ± 0.22 mV and 33.5 ± 7.05 m/s, respectively, to 1.91 ± 0.51 mV and 26.2 ± 4.55 m/s. At 600 µM, terpineol significantly reduced peak-to-peak amplitude...

Effects of the European hornet ( Vespa crabro Linnaeus 1761) crude venom on its own species
Provedor de dados: 80
Autores: Nadolski,Jerzy.
Background Lethal dose 50% is a classical index of toxicity that usually employs small rodents as experimental animals. Therefore, scarce data are available on the effects of venom on invertebrates, particularly the impact of wasp venom on its own species. Findings In the present study, the lethality of Vespa crabro venom on its own species was studied. Lethal dose 50% values of crude venom on workers of hornet Vespa crabro were estimated to be 4.0 mg/kg of body weight. Conclusions Wasps can use their venom apparatus effectively when attacking foreign workers that appear in the immediate vicinity of their nest. The toxins released during stinging are potent enough to kill. The result of this study eliminates the popular myth that venomous animals can be...

Efficacy of HUMN criteria for scoring the micronucleus assay in human lymphocytes exposed to a low concentration of p,p'-DDT
Provedor de dados: 56
Autores: Garaj-Vrhovac,V.; Gajski,G.; Ravlić,S.
The cytokinesis-block micronucleus (CBMN) assay is one of the standard cytogenetic tools employed to assess chromosomal damage subsequent to exposure to genotoxic/cytotoxic agents, and is widely applicable to plant, animal and human cells. In the present study, the CBMN assay was used to assess the baseline damage in binuclear human peripheral blood lymphocytes exposed to 25 µg/L p,p'-DDT for 1, 2, 24, and 48 h by measuring the frequency of micronuclei, nucleoplasmic bridges and nuclear buds. These new scoring criteria facilitated the detection of different types of clastogenic and aneugenic effects induced by this type of pollutant. With these criteria, CBMN can also be used to measure nucleoplasmic bridges which are considered to be consequences of...

Efficiency of the induced mating technique for Toxorhynchites theobaldi (Diptera, Culicidae)
Provedor de dados: 92
Autores: Albeny-Simões,Daniel; Cassol,Angélica Soligo; Breaux,Jennifer A.; Andrade,Mateus R.; Lima,Eraldo; Vilela,Evaldo.
Toxorhynchites mosquitoes play important ecological roles in aquatic microenvironments, and are frequently investigated as potential biological control agents of mosquito disease vectors. Establishment of Toxorhynchites laboratory colonies can be challenging because for some species, mating and insemination either do not occur or require a prohibitive amount of laboratory space for success. Consequently, artificial insemination techniques have been developed to assist with mass rearing of these species. Herein we describe an adapted protocol for colony establishment of T. theobaldi, a species with broad distribution in the Neotropics. The success of the technique and its implications are discussed.

Autores: Souza,Richard Matos de; Sobral,Lafayette Franco; Viégas,Pedro Roberto Almeida; Oliveira Junior,Adilson de; Carvalho,Maria da Conceição Santana.
No Brasil, a maioria dos trabalhos sobre a aplicação de fosfatos de rocha foi realizada em solos do Cerrado com pH menor que 5,5 e baixos teores de Ca trocável. Estudos em condições diferentes dessa, além de raros, têm sido desestimulados, pois esses solos podem apresentar-se restritivos à dissolução dessas fontes, a depender da espécie cultivada e da natureza geológica do fosfato aplicado. Um experimento para estudar a eficiência agronômica dos fosfatos de Bayóvar e Itafós, aplicados por meio da adubação corretiva, foi implantado em um Cambissolo Háplico Ta eutrófico vertissólico de elevado teor de Ca trocável e pH 6.

Provedor de dados: 82
Autores: SANTOS,ADÃO V.; ALBUQUERQUE,GILBERTO S.
Para avaliar os benefícios do cuidado maternal em Antiteuchus sepulcralis (Fabricius), foram realizados estudos de campo, em árvores da planta hospedeira Hibiscus pernambucensis Arruda (Malvaceae). Utilizaram-se três tipos de gaiolas de exclusão: sem o acesso de inimigos naturais (=controle); acesso apenas a parasitóides e acesso a todos os inimigos naturais, além de um tratamento onde as posturas foram avaliadas sem gaiola. Para cada tratamento, usou-se uma condição onde a fêmea protegia a postura e uma onde esta foi removida. Para avaliar a taxa de parasitismo em ambiente natural, foram coletadas posturas no campo em três épocas diferentes. A taxa de predação nas posturas desprovidas de cuidado maternal foi de 100%, em um período inferior a 24 h,...

Provedor de dados: 123
Autores: Silva,Jorge Luiz Mariano da; Sampaio,Luciano Menezes Bezerra.
Este artigo analisou a eficiência técnica de pequenos e médios produtores de camarão no Rio Grande do Norte em duas etapas. Na primeira, foram obtidos escores de eficiência por meio da estimação de fronteiras de produção não paramétricas DEA (Análise de Envoltória de Dados) e FDH (livre descarte). Em seguida, através da estimação de um modelo de regressão censoriada (Tobit) determinou-se a associação dos escores de eficiência com indicadores de gestão dos carcinicultores e a localização de suas fazendas. Os níveis de eficiência técnica foram mais altos para os sistemas de produção extensivo e semi-intensivo. Os resultados também revelaram que algumas práticas de gestão estão associadas aos escores de eficiência. Além disso, produtores localizados em...

El Aguilucho Cola Corta (Buteo brachyurus) en la región chaqueña argentina
Provedor de dados: 68
Autores: Roesler,Ignacio.
La presencia del Aguilucho Cola Corta (Buteo brachyurus) en la Región Chaqueña argentina es muy poco conocida y está basada en pocos datos concretos. En este trabajo se presentan nueve registros nuevos para las provincias de Chaco, Formosa y Santiago del Estero, siendo este último el primero para la provincia. Buteo brachyurus parece no ser tan rara ni ocasional en la Región Chaqueña argentina como se sugiere en la bibliografía actual, sino que existiría regularmente en los distritos Oriental y Occidental. También se sugiere que el morfo oscuro podría ser más común que en otras áreas como en la provincia de Misiones o en el sur de Brasil.

El efecto invernadero producido por el CO2 atmosférico: una nueva interpretación termodinámica
Provedor de dados: 67
Autores: Abril,Eduardo R.
La utilización de modelos para diagnosticar las causas del cambio climático y sus efectos sobre los procesos ecológicos globales ha permitido mejorar nuestra comprensión del fenómeno. Sin embargo, hay evidencias de que los modelos actuales no siempre logran simular los cambios ya documentados alrededor del mundo, posiblemente, debido a que muchos de los procesos que pueden generar cambios climáticos todavía no están totalmente entendidos. En el presente trabajo se presenta una interpretación termodinámica-cinética del efecto invernadero producido por el CO2 desde un nuevo enfoque, el que vincula la temperatura y el calor, y se basa en el criterio corpuscular de la energía. La teoría del complejo activado de la cinética química es interpretada con un...

Los aspectos técnicos, políticos y administrativos del Ordenamiento Territorial Rural (OTR) están estrechamente enlazados, y difícilmente se pueden tratar de forma aislada. Incorporar a la Ciencia y a los científicos en el proceso de OTR permite mejorar algunos factores que definen la calidad del proceso (e.g., acceso a la información, percepción de los problemas, etc.), pero no otros (e.g., disputas de valores e intereses o asimetrías de poder). En su condición de conocimiento sistematizado, la Ciencia aporta un "banco de conocimientos" indispensable. A su vez, puede jugar otro papel clave al ofrecer esquemas de pensamiento y acción, en los cuales los criterios de verdad se asocian a evidencias empíricas y lógicas y no al principio de autoridad o al...

Electrical field stimulation improves bone mineral density in ovariectomized rats
Provedor de dados: 56
Autores: Lirani-Galvão,A.P.R.; Bergamaschi,C.T.; Silva,O.L.; Lazaretti-Castro,M.
Osteoporosis and its consequent fractures are a great social and medical problem mainly occurring in post-menopausal women. Effective forms of prevention and treatment of osteoporosis associated with lower costs and the least side effects are needed. Electrical fields are able to stimulate osteogenesis in fractures, but little is known about their action on osteoporotic tissue. The aim of the present study was to determine by bone densitometry the effects of electrical stimulation on ovariectomized female Wistar rats. Thirty rats (220 ± 10 g) were divided into three groups: sham surgery (SHAM), bilateral ovariectomy (OVX) and bilateral ovariectomy + electrical stimulation (OVX + ES). The OVX + ES group was submitted to a 20-min session of a low-intensity...

Electrocardiographic changes during low-dose, short-term therapy of cutaneous leishmaniasis with the pentavalent antimonial meglumine
Provedor de dados: 56
Autores: Ribeiro,A.L.P.; Drummond,J.B.; Volpini,A.C.; Andrade,A.C.; Passos,V.M.A.
The pentavalent antimonial (Sb5+) meglumine is the drug of choice for the treatment of cutaneous leishmaniasis (CL) in Brazil. Although the cardiotoxicity of high-dose, long-term Sb5+ therapy is well known, the use of low-dose, short-term meglumine has been considered to be safe and relatively free from significant cardiac effects. In order to investigate the cardiotoxicity of low-dose, short-term therapy with meglumine in cutaneous leishmaniasis, 62 CL patients treated with meglumine were studied. A standard ECG was obtained before and immediately after the first cycle of treatment (15 mg Sb5+ kg-1 day-1). The electrocardiographic interpretation was carried out blindly by two investigators using the Minnesota Code. There were no significant differences in...

Autores: Silva,E.M.; Duarte,D.P.F.; da Costa,C.P.
Electrocardiograms (ECG) obtained with standard limb leads and augmented unipolar limb leads were recorded from 17 unanesthetized adult sloths. The animals were held in their habitual position in an experimental chair. We determined heart rate and rhythm from the R-R intervals, the amplitude and duration of each wave, and the duration of the segments and intervals of the ECG. The mean electrical axes of P and T waves and QRS complex were calculated on the basis of the amplitude of these waves in leads I, II, III, aV R, aV L, and aV F. The P wave appeared positive in most tracings with low amplitude in lead II, the QRS complex was generally negative in leads aV R, III and aV F, and no arrhythmias were observed. With a mean ± SD heart rate for all recordings...

Electrolocation-communication discharges of the fish Gymnotus carapo L. (Gymnotidae: Gymnotiformes) during behavioral sleep
Provedor de dados: 56
Autores: Stopa,R.M.; Hoshino,K.
Technical problems have hampered the study of sleep in teleosts. The electrical discharges of Gymnotus carapo L. (Gymnotidae: Gymnotiformes) were monitored to evaluate their ease and reliability as parameters to study sleep. The discharges were detected by electrodes immersed in a glass aquarium and were recorded on a conventional polygraph. G. carapo showed conspicuous signs of behavioral sleep. During these periods, opercular beat rates were counted, electric discharges recorded, and the "sharp discharge increase" (SDI) of the orienting reflex was investigated. All 20 animals monitored maintained electrical discharges during behavioral sleep. The discharge frequencies during sleep (50.3 ± 10.4 Hz) were not significantly different from those observed when...

Autores: Allodi,S.; Taffarel,M.
Invertebrate glial cells show a variety of morphologies depending on species and location. They have been classified according to relatively general morphological or functional criteria and also to their location. The present study was carried out to characterize the organization of glial cells and their processes in the zona fasciculata and in the protocerebral tract of the crab Ucides cordatus. We performed routine and cytochemical procedures for electron microscopy analysis. Semithin sections were observed at the light microscope. The Thiéry procedure indicated the presence of carbohydrates, particularly glycogen, in tissue and in cells. To better visualize the axonal ensheathment at the ultrastructural level, we employed a method to enhance the...

Electro-oscillographic correlation between dorsal raphe nucleus, neocortex and hippocampus during wakefulness before and after serotoninergic inactivation
Provedor de dados: 56
Autores: Fonoff,E.T.; Silva,C.P.C.; Ballester,G.; Timo-Iaria,C.
Theta rhythm in many brain structures characterizes wakefulness and desynchronized sleep in most subprimate mammalian brains. In close relation to behaviors, theta frequency and voltage undergo a fine modulation which may involve mobilization of dorsal raphe nucleus efferent pathways. In the present study we analyzed frequency modulation (through instantaneous frequency variation) of theta waves occurring in three cortical areas, in hippocampal CA1 and in the dorsal raphe nucleus of Wistar rats during normal wakefulness and after injection of the 5-HT1a receptor agonist 8-OH-DPAT into the dorsal raphe. We demonstrated that in attentive states the variation of theta frequency among the above structures is highly congruent, whereas after 8-OH-DPAT injection,...

Electrophysiological evidence for the presence of NR2C subunits of N-methyl-D-aspartate receptors in rat neurons of the nucleus tractus solitarius
Provedor de dados: 56
Autores: Baptista,V.; Ogawa,W.N.; Aguiar,J.F.; Varanda,W.A.
The nucleus tractus solitarius (NTS) plays an important role in the control of autonomic reflex functions. Glutamate, acting on N-methyl-D-aspartate (NMDA) and non-NMDA ionotropic receptors, is the major neurotransmitter in this nucleus, and the relative contribution of each receptor to signal transmission is unclear. We have examined NMDA excitatory postsynaptic currents (NMDA-EPSCs) in the subpostremal NTS using the whole cell patch clamp technique on a transverse brainstem slice preparation. The NMDA-EPSCs were evoked by stimulation of the solitary tract over a range of membrane potentials. The NMDA-EPSCs, isolated pharmacologically, presented the characteristic outward rectification and were completely blocked by 50 µM DL-2-amino-5-phosphonopentanoic...

Electrophysiological measurements of spectral sensitivities: a review
Provedor de dados: 56
Spectral sensitivities of visual systems are specified as the reciprocals of the intensities of light (quantum fluxes) needed at each wavelength to elicit the same criterion amplitude of responses. This review primarily considers the methods that have been developed for electrophysiological determinations of criterion amplitudes of slow-wave responses from single retinal cells. Traditional flash methods can require tedious dark adaptations and may yield erroneous spectral sensitivity curves which are not seen in such modifications as ramp methods. Linear response methods involve interferometry, while constant response methods involve manual or automatic adjustments of continuous illumination to keep response amplitudes constant during spectral scans. In DC...

Elevated atmospheric CO2 increases Eucalyptus urophylla S. T. Blake stem diameter by stimulating cell proliferation and reducing lignin deposition
Provedor de dados: 39
Autores: Innocente,Patricia Sitta; Teixeira,Simone Pádua; Balbuena,Tiago Santana.
ABSTRACT In 2019, the atmospheric CO2 concentration exceeded the 415 ppm milestone for the first time in the human history. According to projections of the Intergovernmental Panel on Climate Change (IPCC), CO2 levels will continue to rise in the future, potentially affecting all living organisms. Plants with C3 metabolism may benefit from rising CO2 levels because the significant losses of photosynthesis, driven by photorespiration could be diminished under this scenario. This study addressed the anatomical changes in the stems of young Eucalyptus urophylla plants induced through cultivation in elevated CO2 (eCO2). Plants cultivated under eCO2 showed increased stem diameter (i.e., radial width of the secondary xylem, secondary phloem and cortex tissues)....

Provedor de dados: 56
Autores: Facundo,H.T.F.; Brandt,C.T.; Owen,J.S.; Lima,V.L.M.
Schistosoma mansoni causes liver disease by inducing granulomatous inflammation. This favors formation of reactive oxygen species, including superoxide ions, hydrogen peroxide and hydroxyl radicals all of which may induce lipid peroxidation. We have evaluated lipid peroxidation in 18 patients with hepatosplenic schistosomiasis mansoni previously treated with oxamniquine followed by splenectomy, ligature of the left gastric vein and auto-implantation of spleen tissue, by measuring levels of erythrocyte-conjugated dienes and plasma malondialdehyde (MDA). Age-matched, healthy individuals (N = 18) formed the control group. Erythrocyte-conjugated dienes were extracted with dichloromethane/methanol and quantified by UV spectrophotometry, while plasma MDA was...

Elimination of micronuclei from microspores in a Brazilian oat (Avena sativa L.) variety
Provedor de dados: 74
Autores: Baptista-Giacomelli,Flávia Roseli; Pagliarini,Maria Suely; Almeida,Juliano Luiz de.
Chromosome elimination in interspecific hybrids is a powerful tool in breeding programs. Of 12 Brazilian oat varieties recommended for cultivation in southern Brazil, one variety, UFRGS 15, presented a new type of chromosome elimination never described in any other species. Chromosomes that produced micronuclei during meiosis were eliminated from microspores as microcytes. The micronucleus reached the microspore wall and formed a kind of bud, separated from the microspore. The eliminated microcytes gave origin to small and sterile pollen grains. The possible applications of this finding for oat breeding are discussed.

An indirect ELISA for the detection of japanese quail IgG specific to Newcastle disease virus (NDV) was developed. The secondary anti-quail IgG was produced in Balb/c mice, by inoculating Freund's complete adjuvant emulsified japanese quail-IgG extract. The purification of IgG was achieved using the caprilic acid method. The ELISA was compared to the haemagglutination-inhibition (HI) test for antibodies to NDV. ELISA cut-off point was established through TG-ROC analysis. Total correlation was observed between the ELISA and the HI, being the ELISA efficient in the identification of positive and negative sera, with high sensitivity and specificity (100%). These results validate the use of the indirect ELISA as an alternative for the detection of NDV-specific...

Abstract Native grasslands in the Campos de Cima da Serra, Brazil, are being converted at speed for exotic tree plantations and cropland. The impact of modified and novel soil conditions on the establishment of native grassland species is unknown; establishment of non-native species, deliberately or accidentally introduced, could be favoured. In a common garden composed of fully randomized replicate samples of soils collected from remnant grassland, former cropland and pine plantations, we tested emergence and establishment of five cold-season species: Native low-tussock grass Piptochaetium montevidense (Spreng.) Parodi; native legume Trifolium riograndense Burkart; naturalized low-tussock grass Vulpia bromoides (L.) Gray; low-tussock grass Holcus lanatus...

Abstract Colistin resistance involving Gram-negative bacilli infections is a challenge for health institutions around of the world. Carbapenem-resistance among these isolates makes colistin the last therapeutic option for this treatment. Colistin resistance among Enterobacteriaceae, Acinetobacter spp., and Pseudomonas spp. was evaluated between 2010 and 2014 years, at Hospital das Clínicas, São Paulo, Brazil. Over five years 1346 (4.0%) colistin resistant Gram-negative bacilli were evaluated. Enterobacteriaceae was the most frequent (86.1%) pathogen isolated, followed by Acinetobacter spp. (7.6%), and Pseudomonas spp. (6.3%). By temporal analysis there was a trend for an increase of colistin resistance among Enterobacteriaceae, but not among...

Autores: Chiappe,Luis M.; Vargas,Alexander.
Desde el inicio del pensamiento evolutivo, el origen de las aves ha constituido uno de los problemas más polémicos de la biología evolutiva. En la actualidad, un gran cúmulo de evidencia indica que dicho problema se encuentra de gran manera resuelto. La evidencia osteológica, oológica, etológica y tegumentaria sustenta fuertemente la hipótesis que las aves descienden de dinosaurios terópodos, en particular a partir de formas clasificadas dentro de Maniraptora. Los contados investigadores que hoy en día se oponen a dicha hipótesis han sustentado sus críticas en observaciones erróneas o dentro de un marco teórico obsoleto. Este trabajo ofrece una breve discusión tanto de las principales líneas de evidencia en sustento de esta hipótesis filogenética como de...

Energy density of freshwater Patagonian organisms
Provedor de dados: 67
Autores: Ciancio,Javier; Pascual,Miguel.
We assessed by using a bomb calorimeter the energy density of the main species of Patagonian freshwater ecosystems, including fish, crustaceans, gastropods, oligochaetes, and insects. Fish (5048-5789 Cal/g) were the most energy density group, followed by insects (5062- 5232), crustaceans (3364-3994), oligochaetes (3471) and gastropods (1143). These data consist on the first direct energy density estimations of freshwater species and are intended as a baseline information for modelling the energy fluxes in Patagonian freshwater ecosystems.

Enganche aéreo de garras entre un Aguilucho Andino (Buteo albigula) y un Aguilucho Común (Buteo polyosoma) en el centro-sur de Chile
Provedor de dados: 68
Autores: Figueroa Rojas,Ricardo A.
Durante el verano de 2002 observé un contacto agresivo directo entre un Aguilucho Andino y un Aguilucho Común en el centro-sur de Chile. Ambas aves, en vuelo, se engancharon de sus garras y empujaron sus pies en el sentido de su contrincante, girando brevemente a modo de "rueda de carreta". Después de eso, ambas aves desengancharon sus garras. Ningún daño físico ni pérdida del control aerodinámico fueron visibles. Este tipo de demostración agresiva, utilizado presumiblemente como defensa territorial, sería el primero documentado para Falconiformes en Chile.

Enhanced anti-tumor effect of a gene gun-delivered DNA vaccine encoding the human papillomavirus type 16 oncoproteins genetically fused to the herpes simplex virus glycoprotein D
Provedor de dados: 56
Autores: Diniz,M.O.; Ferreira,L.C.S.
Anti-cancer DNA vaccines have attracted growing interest as a simple and non-invasive method for both the treatment and prevention of tumors induced by human papillomaviruses. Nonetheless, the low immunogenicity of parenterally administered vaccines, particularly regarding the activation of cytotoxic CD8+ T cell responses, suggests that further improvements in both vaccine composition and administration routes are still required. In the present study, we report the immune responses and anti-tumor effects of a DNA vaccine (pgD-E7E6E5) expressing three proteins (E7, E6, and E5) of the human papillomavirus type 16 genetically fused to the glycoprotein D of the human herpes simplex virus type 1, which was administered to mice by the intradermal (id) route...

Autores: Camargo,I.L.B.C.; Barth,A.L.; Pilger,K.; Seligman,B.G.S.; Machado,A.R.L.; Darini,A.L.C.
In 2000, Enterococcus faecalis resistant to vancomycin was first reported at a tertiary hospital in Porto Alegre, southern Brazil. The resistance spread to other hospitals and surveillance programs were established by hospital infection committees to prevent the spread of vancomycin-resistant enterococci. In February 2002, an isolate initially identified at the genus level as Enterococcus was obtained by surveillance culture (rectal swab) from a patient admitted to a hospital for treatment of septic arthritis in the shoulder. The isolate proved to be resistant to vancomycin by the disc diffusion method and confirmed by an E-test resulting in a minimal inhibitory concentration of  &gt; or = 256 µg/ml. This isolate was sent to a reference laboratory...

Provedor de dados: 55
Autores: Albuquerque,Silvia Eduara Kennerly de; Cavalcante,Ricardo de Souza; Ponce,Daniela; Fortaleza,Carlos Magno Castelo Branco.
Patients submitted to hemodialysis are at a high risk for healthcare-associated infections (HAI). Presently there are scarce data to allow benchmarking of HAI rates in developing countries. Also, most studies focus only on bloodstream infections (BSI) or local access infections (LAI). Our study aimed to provide a wide overview of HAI epidemiology in a hemodialysis unit in southeastern Brazil. We present data from prospective surveillance carried out from March 2010 through May 2012. Rates were compared (mid-p exact test) and temporally analyzed in Shewhart control charts for Poisson distributions. The overall incidence of BSI was 1.12 per 1000 access-days. The rate was higher for patients performing dialysis through central venous catheters (CVC), either...

Epidemiology of Staphylococcus aureus infections and nasal carriage at the Ibn Rochd University Hospital Center, Casablanca, Morocco
Provedor de dados: 55
Autores: Zriouil,Sanaâ Bouhali; Bekkali,Mohammed; Zerouali,Khalid.
Infections caused by Staphylococcus aureus are a major problem in hospitals. The multidrug resistance and the nasal carriage of S. aureus play a key role in the epidemic of these infections. In this prospective study, 160 S. aureus strains were isolated from pathological samples of patients (79 cases) and nasal swabs (81) of cases and controls from January to July 2007. The susceptibility to 16 antibiotics, including cefoxitin, was determined by the agar diffusion method, and methicillin resistance was confirmed by amplifying the mecA gene by polymerase chain reaction (PCR). The prevalence of methicilin-resistant S. aureus (MRSA) was high in the burns (57.7%) and dermatology (39.4%) wards, and the MRSA strains isolated were extremely multi-resistant, but...

Episodes of water deprivation enhance daily hypertonic NaCl intake in rats
Provedor de dados: 56
Autores: Pereira,D.T.B.; David,R.B.; Menani,J.V.; De Luca Jr.,L.A.
Water and 1.8% NaCl intake was recorded daily in adult male rats (N = 6) submitted to four water deprivations plus four sodium appetite tests, each at the end of each 7-day interval, or in controls (non-deprived, N = 6). Water deprivation was achieved by removing water and 1.8% NaCl for 24 h. Water was then offered for 2 h. At the end of this period, 1.8% NaCl was also offered in addition to water (sodium appetite test). Average daily 1.8% NaCl intake was enhanced from 5.2 ± 1.0 to 15.7 ± 2.5 ml from the first to the fifth week in the experimental group and was unchanged in the control group. Daily water intake was not altered in either group. Thus, repeated episodes of water deprivation enhance daily NaCl intake.

Epitope of dengue virus E protein detect human antibodies associated with mild disease: a potential peptide for vaccine development
Provedor de dados: 55
Autores: Sánchez-Burgos,Gilma; Herrera-Nájera,Carla; Cedillo-Rivera,Roberto; Dumonteil,Eric.
ABSTRACT The antigenic potential of seven immunogenic peptides of the dengue virus was evaluated in the sera of patients with dengue confirmed by IgM/IgG serology. Antibodies IgM and IgG against dengue virus peptides were analyzed by ELISA in 31 dengue sero-positive and 20 sero-negative patients. The P5 peptide showed significant IgG immunoreactivity mostly in the sera of patients with dengue without warning signs in comparison with patients with dengue with warning signs, correlating with mild disease. This finding suggests that the low antibody response against P5 epitope could be a risk factor for higher susceptibility to dengue virus infection with warning signs, and that P5 could be a potential antigen for vaccine development.

Provedor de dados: 74
Autores: Vinocur,Myriam E.; Brass,Karin E.; Caetano,Alexandre R.; Silva,Letícia F.; Silva,Aline C.; Silva,Carlos A.M.
The protease inhibitor system (PI) was investigated to ascertain if it can be used as a marker of chronic obstructive pulmonary disease (COPD) in thoroughbred horses. Serum samples were taken from healthy thoroughbreds (n = 13) and those diagnosed as having COPD (n = 24) or inflammatory airway disease (IAD, n = 38) as well as from 3,600 undiagnosed thoroughbred horses. PI allelic and genotypic frequencies were estimated using protein electrophoresis on starch and polyacrylamide gels. The four groups of horses showed high genotypic similarity and none of the observed alleles or genotypes of the equine PI system were found to be associated with COPD.

Helicobacter pylori (HP) infection is endemic worldwide. The proposed treatment is expensive and there are few reports regarding reinfection rates in Brazil. The aim of this study was to compare the eradication rates obtained with two therapeutic options and to evaluate reinfection one year after treatment. This was a prospective randomized trial with 55 patients. Thirty-nine patients had active duodenal ulcer (DU) and 16 non-ulcer dyspepsia (NUD), and all tested positive for HP. Diagnosis was based on at least two positive tests: ultrarapid urease test, histology and/or culture. Patients were randomized to two groups: group OMC treated with 40 mg omeprazole (once a day), 500 mg metronidazole and 250 mg clarithromycin (twice daily) for 7 days, or group NA...

Autores: Schick,Jefferson; Bertol,Ildegardis; Cogo,Neroli Pedro; González,Antonio Paz.
A estimativa de perdas de solo é fundamental para o planejamento conservacionista. Com essa finalidade, destaca-se no Brasil o uso da Equação Universal de Perdas de Solo (USLE), para cuja utilização há escassez de dados obtidos de acordo com o método-padrão desse modelo. Entre os fatores que compõem a USLE, a erodibilidade do solo (fator K) é de difícil obtenção em razão da necessidade de conduzir experimentos em campo por longo tempo sob chuva natural. Com o objetivo de quantificar a erodibilidade do solo em um Cambissolo Húmico em Lages, SC, utilizando-se do método-padrão da USLE, quantificaram-se a erosividade (EI30) das chuvas naturais e as respectivas perdas de solo durante o período de 1993 a 2012. A erodibilidade foi determinada pelo quociente entre...

Erythrocyte glucose-6-phosphate dehydrogenase activity assay and affinity for its substrate under "physiological" conditions
Provedor de dados: 56
Autores: Leite,A.A.; Barretto,O.C. de O.
Glucose-6-phosphate dehydrogenase (G6PD) activity and the affinity for its substrate glucose-6-phosphate were investigated under conditions similar to the physiological environment in terms of ionic strength (I: 0.188), cation concentration, pH 7.34, and temperature (37oC). A 12.4, 10.4 and 21.4% decrease was observed in G6PD B, G6PD A+ and G6PD A- activities, respectively. A Km increase of 95.1, 94.4 and 95.4% was observed in G6PD B, G6PD A+ and G6PD A-, respectively, leading to a marked decrease in affinity. In conclusion, the observation of the reduced activity and affinity for its natural substrate reflects the actual pentose pathway rate. It also suggests a much lower NADPH generation, which is crucial mostly in G6PD-deficient individuals, whose NADPH...

Erythrocyte glucose-6-phosphate dehydrogenase from Brazilian opossum Didelphis marsupialis
Provedor de dados: 56
Autores: Barretto,O.C. de O.; Oshiro,M.; Oliveira,R.A.G.; Fedullo,J.D.L.; Nonoyama,K.
In a comparative study of erythrocyte metabolism of vertebrates, the specific activity of glucose-6-phosphate dehydrogenase (G6PD) of the Brazilian opossum Didelphis marsupialis in a hemolysate was shown to be high, 207 ± 38 IU g-1 Hb-1 min-1 at 37ºC, compared to the human erythrocyte activity of 12 ± 2 IU g-1 Hb-1 min-1 at 37ºC. The apparent high specific activity of the mixture led us to investigate the physicochemical properties of the opossum enzyme. We report that reduced glutathione (GSH) in the erythrocytes was only 50% higher than in human erythrocytes, a value lower than expected from the high G6PD activity since GSH is maintained in a reduced state by G6PD activity. The molecular mass, determined by G-200 Sephadex column chromatography at pH 8.0,...

Erythrocytes may contain a ouabain-insensitive K+-ATPase which plays a role in internal K+ balance
Provedor de dados: 56
Autores: Seguro,L.F.B.C.; Seguro,D.L.B.C.; Helou,C.M.B.
Erythrocytes are useful in evaluating K+ transport pathways involved in internal K+ balance. Several forms of H+,K+-ATPase have been described in nephron segments active in K+ transport. Furthermore, the activity of a ouabain-insensitive isoform of H+,K+-ATPase expressed in collecting duct cells may be modulated by acid-base status. Various assays were performed to determine if a ouabain-insensitive K+-ATPase is present in rat erythrocytes and, if so, whether it plays a role in internal K+ balance. Kinetic studies demonstrated that maximal stimulation of enzyme activity was achieved with 2.5 mM K+ at pH 7.4. Subsequent experiments were performed on erythrocyte membranes collected from animals submitted to varying degrees of K+ homeostasis: control rats,...

Escala de notas para quantificação da ferrugem em Eucalyptus
Provedor de dados: 102
Autores: Junghans,Davi T.; Alfenas,Acelino C.; Maffia,Luiz A.
Utilizando tamanho de pústulas e número de soros como critérios para avaliar a severidade, estabeleceu-se a seguinte escala de notas para quantificação da ferrugem causada por Puccinia psidii em mudas inoculadas de Eucalyptus sp.: S0 = imunidade ou reação de hipersensibilidade, com necrose ou "fleck"; S1 = pústulas puntiformes, &lt; 0,8 mm de diâmetro; S2 = pústulas medianas, de 0,8 a 1,6 mm de diâmetro; e S3 = pústulas grandes, &gt; 1,6 mm de diâmetro. Aferiu-se essa escala mediante o uso do marcador RAPD AT9/917, geneticamente ligado a um gene de resistência à ferrugem, em uma progênie de E. grandis. Apenas as plantas das classes S0 e S1 apresentaram o referido marcador e foram consideradas resistentes. A inconsistência na classificação de plantas...

ABSTRACT Non-native species are a major driver of biodiversity loss. Aquaculture activities play a key role in introductions, including the escape of fishes from fish farm facilities. Here, the impact of flooding due to El Niño rains in 2015/2016 in the Lower and Middle Paranapanema River basin, southern Brazil, was investigated by evaluating fish escapes from 12 fish farms. The flooding resulted in the escape of approximately 1.14 million fishes into the river, encompassing 21 species and three hybrids. Non-native species were the most abundant escapees, especially Oreochromis niloticus (Linnaeus, 1758) and Coptodon rendalli (Boulenger, 1897) (96% of all fish). Only seven native fishes were in the escapee fauna, comprising 1% of all fish. Large floods,...

RESUMO Uma avestruz-do-pescoço-vermelho, com dois anos de idade, apresentava um nódulo no terço médio do esôfago e foi submetida a procedimento cirúrgico. Histologicamente, observou-se uma área focalmente extensa de necrose estendendo-se da túnica mucosa à muscular, e, em algumas secções, à túnica adventícia. Circundando a área de necrose, observou-se uma reação inflamatória composta principalmente por granulócitos e macrófagos, associada à fibroplasia e neovascularização. Em meio às áreas de necrose e inflamação, verificavam-se numerosas imagens negativas de hifas em seções longitudinais e transversais, melhor apreciadas pela coloração de metenamina nitrato de prata de Grocott. O diagnóstico definitivo de infecção por Pythium insidiosum foi confirmado por...

Essays on the history of brazilian dipterology: III. Three remarkable notices from the 18th century, mainly related to myiasis-producing flies (Cochliomyia and Dermatobia)
Provedor de dados: 92
Autores: Papavero,Nelson; Couri,Márcia Souto.
This paper registers reports about dipterans made by three Portuguese who lived in Brazil during the 18th century. Luiz Gomes Ferreira, in his book "Erário mineral" ["Mineral revenue"], wrote curious passages related with myiasis-causing flies of the genus Cochliomyia. José Rodrigues de Mello registered, in Latin verses, the folklore for curing myiases caused by Cochliomyia hominivorax in cattle. Luiz dos Santos Vilhena, in the last of his twenty letters dealing with several aspects of life in Brazil, made reference to horseflies, human bot flies and mosquitos.

Autores: Carbayo,Fernando; Froehlich,Eudóxia Maria.
Nas últimas décadas tem crescido o esforço internacional para conhecer a biodiversidade mundial visando a criação de políticas públicas de conservação. O Brasil vem participando deste esforço, como evidenciam as recentes publicações sobre o estado do conhecimento de vários táxons de organismos. Os macroturbelários (Polycladida e Tricladida, Platyhelminthes) fazem parte da fauna mundialmente menos estudada. Neste trabalho inventariamos por regiões a diversidade da fauna brasileira conhecida de macroturbelários e comparamos esta diversidade com a do resto do mundo. Analisamos também a atividade dos taxonomistas brasileiros do grupo no contexto mundial. Os resultados mostram que praticamente a totalidade das 246 espécies nominais descritas procede das regiões...

Esterase profile in a pyrethroid-resistant Brazilian strain of the cattle tick Boophilus microplus (Acari, Ixodidae)
Provedor de dados: 74
Autores: Baffi,Milla Alves; Pereira,Cícero Donizete; Souza,Guilherme Rocha Lino de; Bonetti,Ana Maria; Ceron,Carlos Roberto; Gourlart,Luiz Ricardo.
The cattle tick Boophilus microplus causes great damage in livestock and is considered one of the most important tropical ectoparasites. The traditional method of control is based on the intensive use of pesticides, however the indiscriminate use of these compounds over the years has led to the selection of resistant ticks. Hydrolases, particularly esterases (EST), have been reported to be associated with acaricide resistance in B. microplus. We compared the esterase profile of susceptible and cypermethrin-resistant strains of adult B. microplus and a pyrethroid susceptible reference strain (the Mozzo strain) using polyacrylamide gel electrophoresis and specific staining. The electrophoretic profiles of protein extracts revealed the presence of four...

Estimating the relative abundance of small mammals when there is no record of catching effort
Provedor de dados: 103
Autores: Cerqueira,Rui; Kajin,Maja.
ABSTRACT Estimates of local population abundances, which require carefully designed sampling procedures, can provide valuable information on population size and density. Even though small mammals are one of the most widely studied vertebrate groups, many surveys have not recorded basic information to estimate local abundances, for instance catching effort. Here we suggest a simple comparative trapping frequency index that can be used as an alternative to the relative abundance index in data sets that only contain the number of species and individuals collected, thus lacking information on sampling effort. To compare trapping frequency and relative abundances we used capture records from more than four years, from seven species of rodents and two marsupial...

Estimation of field capacity from ring infiltrometer-drainage data
Provedor de dados: 90
Autores: Ottoni Filho,Theophilo Benedicto; Ottoni,Marta Vasconcelos; Oliveira,Muriel Batista de; Macedo,José Ronaldo de.
Field capacity (FC) is a parameter widely used in applied soil science. However, its in situ method of determination may be difficult to apply, generally because of the need of large supplies of water at the test sites. Ottoni Filho et al. (2014) proposed a standardized procedure for field determination of FC and showed that such in situ FC can be estimated by a linear pedotransfer function (PTF) based on volumetric soil water content at the matric potential of -6 kPa [θ(6)] for the same soils used in the present study. The objective of this study was to use soil moisture data below a double ring infiltrometer measured 48 h after the end of the infiltration test in order to develop PTFs for standard in situ FC. We found that such ring FC data were an...

Estimation of leaf area for greenhouse cucumber by linear measurements under salinity and grafting
Provedor de dados: 63
Autores: Blanco,Flávio Favaro; Folegatti,Marcos Vinícius.
The measurement of leaf area by linear parameters is a useful tool when plants cannot be destroyed for direct measurement. The objectives of this study were to establish equations to estimate the leaf area of greenhouse-cucumber and to evaluate the effects of salinity and grafting on this estimative. Non-grafted cucumber seedlings, cv. 'Hokushin', were transplanted in a greenhouse and were irrigated with water of different salinities (1.0, 3.2 and 5.0 dS m-1). In the second growing period, the same cultivar was grafted on Cucurbita spp. and the plants were irrigated with water of 1.4, 3.0 and 5.3 dS m-1. Leaves of different sizes were collected from both experiments and leaf area was determined by an integrating area meter. Leaf length (L) and width (W)...

Autores: Coelho Filho,Maurício Antonio; Angelocci,Luiz Roberto; Vasconcelos,Marcos Roberto Baptista; Coelho,Eugênio Ferreira.
O objetivo desse estudo foi avaliar métodos não-destrutivos para a determinação da área foliar de plantas jovens de lima ácida 'Tahiti'(Citrus latifolia Tan.), em campo. Foram utilizadas informações de variáveis biométricas de 28 plantas jovens (0,07 a 1,44 m²) e imagens digitais da área frontal de cada planta (silhueta de copa). Essas variáveis foram correlacionadas com medidas diretas (contagem total de folhas x área foliar média). Como resultado, foi possível estimar a área foliar total das plantas (AFT) com base na equação: AFT = 88,936 x DI - 1,4017 (R²=0,75), em que DI representa o diâmetro do caule 5 cm abaixo do ponto em que a copa foi enxertada, e a silhueta da planta em m² (IM): AFT = 2,4951 x IM (R²=0,72). A área foliar dos ramos secundários das...

Autores: Francisco,Y.A.; Dantas,A.P.V.; Carvalho,M.H.C.; Laurindo,F.R.M.
The complete spectrum of estrogen vascular effects remains unclear. In particular, estrogen effects in the vascular response to profound injury in males have not been explored in detail. Therefore, we submitted 44 male New Zealand rabbits weighing 3.4 ± 0.6 kg to overdistention balloon injury of the right iliac artery. Rabbits were given 17ß-estradiol (5.45 µmol/day, sc) or vehicle for 7 days before and 14 days after injury, when the arteries were examined by post-mortem histomorphometry. Arteriographic caliber was assessed in vivo at baseline and before sacrifice. On day 14 after injury, in vivo arteriographic caliber (baseline = 2.44 ± 0.43 mm) was decreased by 23.1 ± 0.1% in controls and by 44.5 ± 0.1% in estrogen-treated rabbits (P &lt; 0.001). Neither...

Autores: Aguiar,A.C.S.; Machado,V.M.V.; Santos,R.V.; Puoli Filho,J.N.P.; Mota,M.D.S.; Vulcano,L.C.
In this study, 14 "post mortem" equine metacarpal bones were evaluated to correlate the medial III metacarpus perimeter to dorsal bone density of the same region using Computed Tomography and Quantitative Ultrasound (QUS). According to Pearson's test, there were not correlations between these variables. Considering there are few bone densitometry studies in horses and there are many variables that can interfere with bone mineralization, new studies on equine bone density applying standard variables are recommended.

Ethanol-induced colitis prevents oral tolerance induction in mice
Provedor de dados: 56
Autores: Andrade,M.C.; Vaz,N.M.; Faria,A.M.C.
The gut mucosa is a major site of contact with antigens from food and microbiota. Usually, these daily contacts with natural antigens do not result in inflammatory reactions; instead they result in a state of systemic hyporesponsiveness named oral tolerance. Inflammatory bowel diseases (IBD) are associated with the breakdown of the immunoregulatory mechanisms that maintain oral tolerance. Several animal models of IBD/colitis are available. In mice, these include targeted disruptions of the genes encoding cytokines, T cell subsets or signaling proteins. Colitis can also be induced by intrarectal administration of chemical substances such as 2,4,6-trinitrobenzene sulfonic acid in 50% ethanol. We report here a novel model of colitis induced by intrarectal...

Autores: Carneiro,Marco Antonio A.; Cangussú,Silvia D.; Fernandes,G. Wilson.
Problems regarding the order of authorship of scientific papers have become more frequent and more abusive. These problems may have heightened due to the ever increasing pressure to "publish or perish" in the academic world, given that the publication of scientific articles has become the benchmark of success in a field with few job opportunities. This article reviews the abuses in the authorship of scientific papers. Different examples are given of the most common problems and recommendations are provided for authors and journal editors.

Desde 1995, pastos formados com Brachiaria brizantha cv. Marandu vêm sendo devastados por uma doença cujo sintoma típico é a morte de touceiras. Das amostras de plantas coletadas nos municípios de Paragominas (PA), Carutapera (MA) e Araguaína (TO), exibindo sintomas iniciais da doença, bem como, de sementes obteve-se quatro isolados de Pythium spp. e um de Rhizoctonia solani associados aos tecidos doentes. Os resultados dos testes de patogenicidade comprovaram que o principal agente da podridão do coleto do capim-braquiarão é Pythium periilum. A infestação do solo com mistura de inóculo dos três isolados de P. periilum e de R. solani resultou em elevada quantidade de doença (p&lt;0,01). Na presença de alta população de R. solani, no solo, a associação...

Abscisic acid (ABA) regulates stress responses in plants, and genomic tools can help us to understand the mechanisms involved in that process. FAPESP, a Brazilian research foundation, in association with four private forestry companies, has established the FORESTs database (&lt;A HREF="https://forests.esalq.usp.br"&gt;https://forests.esalq.usp.br&lt;/A&gt;). A search was carried out in the Eucalyptus expressed sequence tag database to find ESTs involved with 9-cis epoxycarotenoid dioxygenase (NCED), the regulatory enzyme for ABA biosynthesis, using the basic local BLAST alignment tool. We found four clusters (EGEZLV2206B11.g, EGJMWD2252H08.g, EGBFRT3107F10.g, and EGEQFB1200H10.g), which represent similar sequences of the gene that produces NCED. Data...

Autores: Reyna,P; Rodríguez Pardina,P.
Los métodos tradicionales de diagnóstico son inespecíficos para la identificación de begomovirus. Actualmente se usan técnicas moleculares, que requieren equipamientos sofisticados o procedimientos complejos. La técnica de amplificación mediante recombinasa y polimerasa (RPA) es similar a la reacción en cadena de la polimerasa (PCR), sensible, específica, pero opera a temperatura constante. Con el fin de evaluar la utilización de esta técnica para la detección de begomovirus presentes en soja y poroto en Argentina, se diseñaron iniciadores específicos. Se probaron inicialmente por PCR, con clones de virus detectados en el país, y se logró amplificar una banda de 371 pb.

Evaluación preliminar de las poblaciones de Pyrrhura orcesi en remanentes boscosos de la provincia de El Oro, Ecuador
Provedor de dados: 68
Autores: Echeverría Vaca,Gabriela; Garzón Santomaro,César.
El Perico de El Oro (Pyrrhura orcesi) es una especie endémica de Ecuador que se encuentra en peligro de extinción. La principal amenaza para la especie es la fragmentación del hábitat. Se evaluó la abundancia de Pyrrhura orcesi en tres áreas no protegidas ubicadas en los bosques nublados de la provincia de El Oro mediante observaciones directas y registros auditivos en puntos fijos de conteo. El número máximo registrado para las tres áreas fue de 254 individuos. La abundancia relativa fue similar en las tres áreas. La abundancia no estuvo asociada con la cobertura de bosque. Los resultados del trabajo muestran el valor que tienen los remanentes boscosos en el área de estudio, en los cuales Pyrrhura orcesi puede persistir a pesar no tener ninguna protección.

Autores: Barboza,L.A.; Ghisi,N.C.
Huntington disease (HD) is an incurable neurodegenerative disorder caused by a dominant mutation on the 4th chromosome. We aim to present a scientometric analysis of the extant scientific undertakings devoted to better understanding HD. Therefore, a quantitative study was performed to examine the current state-of-the-art approaches that foster researchers’ understandings of the current knowledge, research trends, and research gaps regarding this disorder. We performed literature searches of articles that were published up to September 2016 in the “ISI Web of Science™” (http://apps.webofknowledge.com/). The keyword used was “Huntington disease”. Of the initial 14,036 articles that were obtained, 7732 were eligible for inclusion in the study according to...

The Horne-Östberg questionnaire partly covers some factors that may be important determinants of peak time and characterize patterns of behavior. We conducted a study for the evaluation of self-reported behavioral states (hunger sensation, availability for study, physical exercise, solving daily problems, and time preferences) as expressions of underlying cyclic activity. Three hundred and eighteen community subjects without history of medical, psychiatric, or sleep disorders were evaluated in a cross-sectional design. A self-report about daily highest level of activity was used to categorize individuals into morning, evening, and indifferently active. Time-related behavioral states were evaluated with 23 visual analog questions. The responses to most...

Eighty-six newly diagnosed multiple myeloma (MM) patients from a public hospital of São Paulo (Brazil) were evaluated by cIg-FISH for the presence of del(13)(q14), t(4;14)(p16.3;q32) and del(17)(p13). These abnormalities were observed in 46.5, 9.3, and 7.0% of the patients, respectively. In order to identify the possible role of del(13)(q14) in the physiopathology of MM, we investigated the association between this abnormality and the proliferative and apoptotic indexes of plasma cells. When cases demonstrating t(4;14)(p16.3;q32) and del(17)(p13) were excluded from the analysis, we observed a trend towards a positive correlation between the proportion of cells carrying del(13)(q14) and plasma cell proliferation, determined by Ki-67 expression (r = 0.23, P...

Abstract Tuberculosis (TB) is still considered a major global public health problem in the world and there is a concern about the worldwide increase of drug-resistance (DR). This paper describes the analysis of three Mycobacterium tuberculosis isolates from a single patient collected over a long treatment period of time. DR was initially investigated through phenotypic testing, followed by line probe assays (LPAs) and whole genome sequencing (WGS). It presents an intriguing situation where a multidrug-resistant (MDR-) TB case was diagnosed and treated based only on late phenotypic drug susceptibility testing of isolate 1. During the treatment, another two isolates were cultivated: isolate 2, nine months after starting MDR-TB treatment; and isolate 3,...

Evaluation of soil-microbial communities by their CLPP: Standardization of a laboratory technique to replace commercial available microplates
Provedor de dados: 67
Autores: Di Salvo,Luciana P.; García De Salamone,Inés E.
Variation of soil-microbial communities are good bioindicators of human impacts in soils, such as different soils management or contamination. Considering that traditional methods of isolation and taxonomic analysis do not consider the functionality of the microbial community, Community-Level Physiological Profiles (CLPP) emerged as a complementary methodology to study microbial communities. Several studies have shown that Biolog® EcoPlates® are very useful for determining physiological differences between communities from different samples. However, commercial microplates have some disadvantages which led us to the idea of replacing them by microplates prepared in the laboratory (Laboratory's). Here, we compared both types of microplates using soil...

Provedor de dados: 56
Autores: Bayeux,M.C.; Fernandes,A.T.; Foglio,M.A.; Carvalho,J.E.
The species Cordia curassavica (Boraginaceae), known popularly as "erva baleeira", is used in folk medicine for the treatment of several inflammatory processes and as a healing agent. The objective of the present study was to evaluate the antiedematogenic activity of crude dichloromethane extracts of Cordia curassavica and of the artemetin-enriched fraction. The crude extract and artemetin fraction were tested in the model of carrageenin-induced paw edema in male Swiss mice (25-30 g). The crude dichloromethane extract (300 and 1000 mg/kg, po, N = 6) showed significant antiedematogenic activity, reducing the edema by 42, 57 and 45% and 46, 62 and 69%, 3, 4 and 5 h after carrageenin administration, respectively. Indomethacin (10 mg/kg, po, N = 6) reduced the...

Autores: Peng,Yunping; Wu,Junlin; Liu,Xiaoyun; Wang,Jihua; Li,Wenmei.
Influenza viruses cause significant morbidity and mortality in both children and adults during local outbreaks or epidemics. Therefore, a rapid test for influenza A&amp;B would be useful. This study was conducted to evaluate the clinical performance of the Wondfo influenza A&amp;B test for rapid diagnosis of influenza A H1N1 Infection. The rapid testing assay could distinguish infection of influenza A and B virus. The reference viral strains were cultured in MDCK cells while TCID50 if the viruses were determined. The analytical sensitivity of the Wondfo kit was 100 TCID50/ml. The Wondfo kit did not show cross reactivity with other common viruses. 1928 suspected cases of influenza A (H1N1) virus infection were analyzed in the Wondfo influenza A&amp;B test...

Provedor de dados: 56
Autores: Siebra,M.X.; Santos,M.A.; Almeida,T.L.P.; Leite,A.C.R.M.; Cunha,F.Q.; Rocha,F.A.C.
Pemphigus is an inflammatory autoimmune disorder of the skin. Nitric oxide (NO) is an inflammatory mediator linked to a variety of physiological and pathophysiological phenomena that include skin tumors, psoriasis, urticaria, and atopic dermatitis. Inflammatory cells present in pemphigus lesions are important sources of NO production. We investigated whether NO is involved in pemphigus. A prospective cohort study was conducted at the Dermatology Service of the Hospital Universitário Walter Cantídio of the Federal University of Ceará. All patients seen at the outpatient clinic between August 2000 and July 2001, with a clinically and histologically confirmed diagnosis of pemphigus were included. The median age was 42.5 years (range: 12-69 years) with a male...

Evidence of ectopic recombination and a repeat-induced point (RIP) mutation in the genome of Sclerotinia sclerotiorum, the agent responsible for white mold
Provedor de dados: 74

Abstract Two retrotransposons from the superfamilies Copia and Gypsy named as Copia-LTR_SS and Gypsy-LTR_SS, respectively, were identified in the genomic bank of Sclerotinia sclerotiorum. These transposable elements (TEs) contained direct and preserved long terminal repeats (LTR). Domains related to codified regions for gag protein, integrase, reverse transcriptase and RNAse H were identified in Copia-LTR_SS, whereas in Gypsy-LTR_SS only domains for gag, reverse transcriptase and RNAse H were found. The abundance of identified LTR-Solo suggested possible genetic recombination events in the S. sclerotiorum genome. Furthermore, alignment of the sequences for LTR elements from each superfamily suggested the presence of a RIP (repeat-induced point mutation)...

Evidence that blood pressure remains under the control of arterial baroreceptors in renal hypertensive rats
Provedor de dados: 56
Autores: Trindade Jr.,A.S.; Moreira,E.D.; Silva,G.J.J.; Krieger,E.M.
The purpose of the present study was to determine the range of the influence of the baroreflex on blood pressure in chronic renal hypertensive rats. Supramaximal electrical stimulation of the aortic depressor nerve and section of the baroreceptor nerves (sinoaortic denervation) were used to obtain a global analysis of the baroreceptor-sympathetic reflex in normotensive control and in chronic (2 months) 1-kidney, 1-clip hypertensive rats. The fall in blood pressure produced by electrical baroreceptor stimulation was greater in renal hypertensive rats than in normotensive controls (right nerve: -47 ± 8 vs -23 ± 4 mmHg; left nerve: -51 ± 7 vs -30 ± 4 mmHg; and both right and left nerves: -50 ± 8 vs -30 ± 4 mmHg; P &lt; 0.05).

Evidence that urocortin is absent from neurons of the Edinger-Westphal nucleus in pigeons
Provedor de dados: 56
Autores: Cavani,J.A.; Reiner,A.; Cuthbertson,S.L.; Bittencourt,J.C.; Toledo,C.A.B.
The Edinger-Westphal nucleus (EWN) is a central preganglionic parasympathetic cell group that gives rise to cholinergic input to the ciliary ganglion, thereby regulating several neurovegetative ocular functions. Recently, the supposed presence of the neuropeptide urocortin (UCN) has been reported in EWN neurons in rodent brain. The purpose of the present study was to examine the distribution of UCN in avian brain and to investigate by immunohistochemical analysis the possible use of this substance as an EWN marker in a non-mammalian class of vertebrates. Brain tissue of pigeons was incubated with a specific antibody against UCN and the results showed labeling of many small neurons, forming a double wing in the dorsal mesodiencephalic transition area.

Evolution of circadian organization in vertebrates
Provedor de dados: 56
Circadian organization means the way in which the entire circadian system above the cellular level is put together physically and the principles and rules that determine the interactions among its component parts which produce overt rhythms of physiology and behavior. Understanding this organization and its evolution is of practical importance as well as of basic interest. The first major problem that we face is the difficulty of making sense of the apparently great diversity that we observe in circadian organization of diverse vertebrates. Some of this diversity falls neatly into place along phylogenetic lines leading to firm generalizations: i) in all vertebrates there is a "circadian axis" consisting of the retinas, the pineal gland and the...

The objectives of this overview are to describe the past and potential contributions of birth cohorts to understanding chronic disease aetiology; advance a justification for the maintenance of birth cohorts from low- and middle-income countries (LMIC); provide an audit of birth cohorts from LMIC; and, finally, offer possible future directions for this sphere of research. While the contribution of birth cohorts from affluent societies to understanding disease aetiology has been considerable, we describe several reasons to anticipate why the results from such studies might not be directly applied to LMIC. More than any other developing country, Brazil has a tradition of establishing, maintaining and exploiting birth cohort studies. The clear need for a...

Neste artigo procura-se mostrar a heterogeneidade da agricultura brasileira, que está composta por um segmento altamente produtivo e eficiente, de tipo patronal empresarial; um segmento também eficiente e rentável, de tipo familiar empresarial; e um segmento de agricultores familiares pobres ou camponeses que produz para autoconsumo, mora no estabelecimento, gera emprego para os filhos, e que não migra porque seu custo de oportunidade para migrar é baixo. A inexistência de economias de escala na agricultura, a baixa lucratividade da atividade em função da baixa rotatividade do capital fixo, o ambiente concorrencial do mercado agrícola e os riscos que atingem a atividade (clima, pragas e preços) fazem com que não haja interesse em monopolizá-lo por um setor...

Entrapment neuropathy is a group of clinical disorders involving compression of a peripheral nerve and interference with nerve function mostly through traction injury. We have investigated the chronic compression of peripheral nerves as an experimental procedure for detecting changes in ultrastructural nerve morphology. Adult hamsters (Mesocricetus auratus, N = 30) were anesthetized with a 25% pentobarbital solution and received a cuff around the right sciatic nerve. Left sciatic nerves were not operated (control group). Animals survived for varying times (up to 15 weeks), after which they were sacrificed and both sciatic nerves were immediately fixed with a paraformaldehyde solution. Experimental nerves were divided into segments based upon their distance...

Provedor de dados: 56
Autores: Machado-Pinheiro,W.; Faria Jr.,A.J.P.; Gawryszewski,L.G.; Ribeiro-do-Valle,L.E.
Previous studies have shown that saccadic eye responses but not manual responses were sensitive to the kind of warning signal used, with visual onsets producing longer saccadic latencies compared to visual offsets. The aim of the present study was to determine the effects of distinct warning signals on manual latencies and to test the premise that the onset interference, in fact, does not occur for manual responses. A second objective was to determine if the magnitude of the warning effects could be modulated by contextual procedures. Three experimental conditions based on the kind of warning signal used (visual onset, visual offset and auditory warning) were run in two different contexts (blocked and non-blocked). Eighteen participants were asked to...

Experimental myocardial hypertrophy induced by a minimally invasive ascending aorta coarctation
Provedor de dados: 56
Autores: Martins,A.S.; Aguilera,N.W.; Matsubara,B.B.; Bregagnollo,E.A.
Ascending aorta coarctation was produced by a minimally invasive technique in rabbits. Animal mortality was 5%. Morphometric and hemodynamic parameters were evaluated. A parabiotically isolated heart model was used to assess the hemodynamic parameters. Left ventricular weight/body weight ratio and muscle area showed clear evidence of hypertrophy when compared to control. The hemodynamic changes in the isolated heart model suggested decreased diastolic and systolic function in the coarcted group. The present model produced hypertrophy with low mortality rates as a result of its less invasive nature.

Autores: Berchieri Júnior,Angelo; Oliveira,Gláucia Helaine de; Pinheiro,Lucas Augusto Soeiro; Barrow,Paul A.
Although the epidemiology of fowl typhoid in chickens supposedly involves a vertical transmission stage, a previous work run by the authors has suggested that this did not happen in a commercial line of laying hens highly susceptible to systemic disease with Salmonella Gallinarum. A new experiment was carried out in two other lines of commercial layers, considerably more resistant than those used in the previous study. Clinical fowl typhoid was not observed, but Salmonella Gallinarum was isolated from the spleen and liver four weeks after infection and, sporadically, from the ovary.

Expression and characterization of an N-truncated form of the NifA protein of Azospirillum brasilense
Provedor de dados: 56
Autores: Nishikawa,C.Y.; Araújo,L.M.; Kadowaki,M.A.S.; Monteiro,R.A.; Steffens,M.B.R.; Pedrosa,F.O.; Souza,E.M.; Chubatsu,L.S.
Azospirillum brasilense is a nitrogen-fixing bacterium associated with important agricultural crops such as rice, wheat and maize. The expression of genes responsible for nitrogen fixation (nif genes) in this bacterium is dependent on the transcriptional activator NifA. This protein contains three structural domains: the N-terminal domain is responsible for the negative control by fixed nitrogen; the central domain interacts with the RNA polymerase σ54 co-factor and the C-terminal domain is involved in DNA binding. The central and C-terminal domains are linked by the interdomain linker (IDL). A conserved four-cysteine motif encompassing the end of the central domain and the IDL is probably involved in the oxygen-sensitivity of NifA. In the present study,...

Autores: Figueiredo,L.T.M.; Moreli,M.L.; Borges,A.A.; Figueiredo,G.G.; Souza,R.L.M.; Aquino,V.H.
Hantavirus cardiopulmonary syndrome (HCPS) has been recognized as an important public heath problem. Five hantaviruses associated with HCPS are currently known in Brazil: Juquitiba, Araraquara, Laguna Negra-like, Castelo dos Sonhos, and Anajatuba viruses. The laboratory diagnosis of HCPS is routinely carried out by the detection of anti-hantavirus IgM and/or IgG antibodies. The present study describes the expression of the N protein of a hantavirus detected in the blood sample of an HCPS patient. The entire S segment of the virus was amplified and found to be 1858 nucleotides long, with an open reading frame of 1287 nucleotides that encodes a protein of 429 amino acids. The nucleotide sequence described here showed a high identity with the N protein gene...

The purpose of the present study was to investigate the expression (mRNA) of CD40 ligand (CD40L), interferon-gamma (IFN-gamma) and Fas ligand (FasL) genes in human cardiac allografts in relation to the occurrence of acute cardiac allograft rejection as well as its possible value in predicting acute rejection. The mRNA levels were determined by a semiquantitative reverse transcriptase-polymerase chain reaction method in 39 samples of endomyocardial biopsies obtained from 10 adult cardiac transplant recipients within the first six months after transplantation. Biopsies with ongoing acute rejection showed significantly higher CD40L, IFN-gamma and FasL mRNA expression than biopsies without rejection. The median values of mRNA expression in biopsies with and...

Expression of DLK1 and MEG3 genes in porcine tissues during postnatal development
Provedor de dados: 74
Autores: Oczkowicz,Maria; Piestrzyska-Kajtoch,Agata; Piórkowska,Katarzyna; Rejduch,Barbara; Rózycki,Marian.
The Drosophila-like homolog 1 (DLK1), a transmembrane signal protein similar to other members of the Notch/Delta/Serrate family, regulates the differentiation process in many types of mammalian cells. Callipyge sheep and DLK1 knockout mice are excellent examples of a fundamental role of the gene encoding DLK1 in muscle growth and fat deposition. DLK1 is located within co-regulated imprinted clusters (the DLK1/DIO3 domain), along with other imprinted genes. Some of these, e.g. the RNA coding MEG3 gene, presumedly interfere with DLK1 transcription. The aim of our study was to analyze DLK1 and MEG3 gene expression in porcine tissues (muscle, liver, kidney, heart, brain stem) during postnatal development. The highest expression of both DLK1 and MEG3 variant 1...

Expression of dorsal-ventral genes during early development of Rhynchosciara americana embryos
Provedor de dados: 56
Autores: Carvalho,J.C.; Rocha,D.N.; Bruno,R.V.; Vanario-Alonso,C.E.; Abdelhay,E.
The establishment of dorsal-ventral polarity in Drosophila is a complex process which involves the action of maternal and zygotically expressed genes. Interspecific differences in the expression pattern of some of these genes have been described in other species. Here we present the expression of dorsal-ventral genes during early embryogenesis in the lower dipteran Rhynchosciara americana. The expression of four genes, the ventralizing genes snail (sna) and twist (twi) and the dorsalizing genes decapentaplegic (dpp) and zerknüllt (zen), was investigated by whole-mount in situ hybridization. Sense and antisense mRNA were transcribed in vitro using UTP-digoxigenin and hybridized at 55°C with dechorionated fixed embryos. Staining was obtained with...

Grapevine leafroll-associated virus 3 (GLRaV-3), the main viral species of the grapevine leafroll complex, causes yield and quality reduction in grapes (Vitis spp.). The coat protein gene was RT-PCR-amplified from total RNA extracted from infected grapevine leaves and the amplified fragment was cloned and completely sequenced. The fragment was subsequently subcloned into the pRSET-C expression vector. The recombinant plasmid was used to transform Escherichia coli BL21:DE3 and express the capsid protein. The coat protein, fused to a 6 His-tag, was purified by affinity chromatography using an Ni-NTA resin. The identity of the purified protein was confirmed by SDS-PAGE and Western blot. The in vitro-expressed protein was quantified and used for rabbit...

Autores: Oliveira,M.C.; Marroni,C.P.; Pizarro,C.B.; Pereira-Lima,J.F.; Barbosa-Coutinho,L.M.; Ferreira,N.P.
Inactivating mutations of TP53, a tumor suppressor gene, are associated with abnormal cell proliferation. Although p53 expression is common in many human malignancies, p53 protein has seldom been evaluated in pituitary tumors. When detected, the percentage of p53-positive cells is low, and, in general, it is exclusive for invasive lesions. The aim of the present study was to use immunohistochemistry to determine the presence of p53 protein in pituitary adenomas from tumor samples of 163 surgeries performed in 148 patients (40% male, 60% female). In 35% of the cases the adenoma was nonfunctional, while in the others it was associated with PRL, GH and/or ACTH endocrine hypersecretion syndrome. Macroadenomas were observed in 83.2% of the cases with available...

Leprosy is caused by Mycobacterium leprae, which induces chronic granulomatous infection of the skin and peripheral nerves. The disease ranges from the tuberculoid to the lepromatous forms, depending on the cellular immune response of the host. Chemokines are thought to be involved in the immunopathogenesis of leprosy, but few studies have investigated the expression of chemokine receptors on leukocytes of leprosy patients. In the present study, we evaluated 21 leprosy patients (M/F: 16/5) with a new diagnosis from the Dermatology Outpatient Clinic of the University Hospital, Federal University of Minas Gerais. The control group was composed of 20 healthy members (M/F: 15/5) of the community recruited by means of announcements. The expression of CCR2,...

Autores: Biagolini-Jr,Carlos; Costa,Mariellen C.; Perrella,Daniel F.; Zima,Paulo V.Q.; Ribeiro-Silva,Lais; Francisco,Mercival R.
ABSTRACT Over the last two decades, several studies have shown that the mating systems of various birds are more complex than previously believed, and paternity tests performed with molecular techniques have proved, for instance, that the commonly observed social monogamy often presents important variations, such as extra-pair paternity. However, data are still largely biased towards temperate species. In our study, at an area of the Brazilian Atlantic Forest, we found broods containing at least one extra-pair young (EPY) in the socially monogamous White-necked Thrush Turdus albicollis (Vieillot, 1818). Paternity tests using six heterologous microsatellite loci revealed that four of 11 broods (36.4%) presented at least one extra-pair young (EPY). This rate...

We investigated the association of eye color with the dominant-subordinate relationship in the fish Nile tilapia, Oreochromis niloticus. Eye color pattern was also examined in relation to the intensity of attacks. We paired 20 size-matched fish (intruder: 73.69 ± 11.49 g; resident: 75.42 ± 8.83 g) and evaluated eye color and fights. These fish were isolated in individual aquaria for 10 days and then their eye color was measured 5 min before pairing (basal values). Twenty minutes after pairing, eye color and fights were quantified for 10 min. Clear establishment of social hierarchy was observed in 7 of 10 pairs of fish. Number of attacks ranged from 1 to 168 among pairs. The quartile was calculated for these data and the pairs were then divided into two...

Autores: ALMEIDA,ANA CARLA L.; OLIVEIRA,ELIZABETH; RESENDE,RENATO O.
O mosaico comum do milho (Zea mays) destaca-se, atualmente, entre as doenças mais importantes dessa cultura, sendo causada por um complexo de potyvirus transmitido por afídeos. Esse trabalho teve por objetivo a identificação de fatores que podem contribuir para a incidência dessa virose e disseminação do seu agente causal. Plântulas de 115 cultivares dos Ensaios Nacionais de Milho-Centro foram submetidas a quatro inoculações com o complexo viral, utilizando-se, em cada uma, parcelas com cinco plantas de cada cultivar. A maioria das cultivares mostrou-se suscetível, apresentando sintomas da virose, aos 15 dias após a inoculação. Espécies de gramíneas também foram inoculadas e mostraram-se hospedeiras desses vírus. Através do teste dot-ELISA, a presença dos...

Autores: Mühlbauer,M.; Duarte,D.P.F.; Gilmore,D.P.; da Costa,C.P.
The present study was carried out to assess the possibility of measuring fecal steroid hormone metabolites as a noninvasive technique for monitoring reproductive function in the three-toed sloth, Bradypus variegatus. Levels of the estradiol (E2) and progesterone (P4) metabolites were measured by radioimmunoassay in fecal samples collected over 12 weeks from 4 captive female B. variegatus sloths. The validation of the radioimmunoassay for evaluation of fecal steroid metabolites was carried out by collecting 10 blood samples on the same day as defecation. There was a significant direct correlation between the plasma and fecal E2 and P4 levels (P &lt; 0.05, Pearson's test), thereby validating this noninvasive technique for the study of the estrous cycle in...

Feeding dynamics of Cichla kelberi Kullander &amp;amp; Ferreira, 2006 introduced into an artificial lake in southeastern Brazil
Provedor de dados: 83
Autores: Villares Junior,Gilberto Aparecido; Gomiero,Leandro Muller.
The objective of this study was to characterize the seasonally of the diet of Cichla kelberi in an artificial lake in Leme-SP, determining the food items and their relation to the sex and gonadal maturity of the fish sampled. The diet of C. kelberi presents a dynamic in three different periods: winter months were characterized by low feeding activity and a high concentration of undetermined fish; increase in feeding activity occurred in the spring, with Tilapia sp. being the dominant food item; and a high rate of cannibalism was observed in the summer and early fall. The plasticity in the composition of the diet was marked by quantity of prey available during the different periods of the year, and the reproductive period.

Female novelty and the courtship behavior of male guinea pigs (Cavia porcellus)
Provedor de dados: 56
Autores: Cohn,D.W.H.; Tokumaru,R.S.; Ades,C.
In several rodent species, an increase or recovery of sexual behavior can be observed when sexually satiated males are placed in contact with a novel mate. In order to assess the influence of female novelty on the courtship behavior of guinea pigs (Cavia porcellus), four adult males were observed during four daily 15-min sessions while interacting with the same pregnant female (same-female sessions). A new female was presented during the fifth session (switched-female session). The duration of behavioral categories was obtained from videotape records using an observational software. From the first to the second session, all males decreased the time allocated to investigating (sniffing and licking), following, and mounting the female, and that response did...

Fertility of male adult rats submitted to forced swimming stress
Provedor de dados: 56
Autores: Mingoti,G.Z.; Pereira,R.N.; Monteiro,C.M.R.
We investigated whether stress interferes with fertility during adulthood. Male Wistar rats (weighing 220 g in the beginning of the experiment) were forced to swim for 3 min in water at 32ºC daily for 15 days. Stress was assessed by the hot-plate test after the last stressing session. To assess fertility, control and stressed males (N = 15 per group) were mated with sexually mature normal females. Males were sacrificed after copulation. Stress caused by forced swimming was demonstrated by a significant increase in the latency of the pain response in the hot-plate test (14.6 ± 1.25 s for control males vs 26.0 ± 1.53 s for stressed males, P = 0.0004). No changes were observed in body weight, testicular weight, seminal vesicle weight, ventral prostate weight...

Autores: Domingues,Renan Barros; Santos,Márcio Vega dos; Leite,Fernando Brunale Vilela de Moura; Senne,Carlos.
ABSTRACT The precise diagnosis of bacterial meningitis is essential. Cytological and biochemical examination of cerebrospinal fluid (CSF) are not specific. Conventional methods for bacterial meningitis lack sensitivity or take too long for a final result. Therefore, other methods for rapid and accurate diagnosis of central nervous system infections are required. FilmArray meningitis/encephalitis (ME) panel is a PCR multiplex for simultaneous and rapid identification of 14 pathogens, including 6 bacteria, 7 viruses, and Cryptococcus. We evaluated 436 CSF samples submitted to FilmArray ME Panel. Among them, 25 cases were positive for bacteria, being Streptococcus pneumonia the most frequent (48 %). Among positive cases for bacteria, 60 % were positive only...

Autores: Helene,A.F.; Xavier,G.F.
Graduate programs provide the highest level of formal education and thus are crucial for the development of any country. However, official Brazilian data clearly show a dramatic decrease in the number and values of scholarships available to graduate programs in Brazil over the last few years, despite the importance and growth of such programs. Between 1995 and 2004, investment by the Coordenadoria de Aperfeiçoamento de Pessoal do Ensino Superior (CAPES, subordinate to the Ministry of Education and Culture) in funding scholarships, corrected for inflation in the period, actually decreased by 51%. In addition, during the period between 1994 and 2004, there was a loss of about 60% in the purchasing power of the graduate scholarships provided by CAPES and the...

Firewood as a pathway for insect introductions: What are the risks of ant invasions in Patagonia?
Provedor de dados: 67
Autores: Werenkrut,Victoria; Pirk,Gabriela I; Lescano,María N; Benclowicz,José D; Elizalde,Luciana.
Firewood can act as a long-distance dispersal vector for wood-infesting insects both within and among countries. Recently, we detected the alien carpenter ant Camponotus mus in firewood transported from central Argentina to Patagonia. This species generates significant economic losses in its native range and has invader potential. Moreover, global warming and the increasing anthropogenic disturbance in Patagonian ecosystems make them highly susceptible to insect invasions. This is especially alarming considering the current lack of sanitary controls of incoming goods into the region. To prevent insect introductions via firewood, it is crucial to implement a joint efort among the scientific community, control organisms, government and end user.

A clinical Providencia stuartii isolate SM662 was recovered from a patient hospitalized in the intensive care unit at the Military hospital, Tunisia. This isolate was resistant to penicillins, cephalosporins, aminoglycosides and fluoroquinolones. A marked in vitro synergy between ceftazidime or cefotaxime and amoxicillin-clavulanic acid on Mueller-Hinton agar plates suggested the presence of an extended-spectrum-β-lactamase. In addition, an unusual synergy was found between cefepime or aztreonam, and cefoxitin or imipenem on a double disk synergy test suggesting a VEB-type extended-spectrum-β-lactamase. The characterization of β-lactamases and associated resistance genes was performed by isoelectric focusing, polymerase chain reaction and nucleotide...

Autores: Pastori,M.C.; Fenocchio,A.S.; López,P.A.
Thirty-six specimens of Schizodon nasutus (Anostomidae-Characiformes) from the middle Paraná River (Posadas, Argentina) were analyzed cytogenetically. The karyotype of this species was similar to those described for this species in the literature. C-banding technique showed a rich heterochromatic pattern relative to other Anostomidae species. The NORs were located on one chromosome pair in terminal position and showed a very marked size heteromorphism. A microchromosome was observed with a frequency of about 20% in the sample studied. This additional element was punctiform, negative C-band, and constant in all metaphase plates of the seven carriers. The present study is the first karyotypic approach to Schizodon nasutus from Argentina and the first...

First experimental evidence that a harvestman (Arachnida: Opiliones) detects odors of non-rotten dead prey by olfaction
Provedor de dados: 103
Autores: Costa,Thaiany Miranda; Willemart,Rodrigo Hirata.
Harvestmen feed on live, dead and fresh, or decomposing animals, fungi, and plant matter, being very dependent on chemoreception to find food. Herein we performed an experiment to test if individuals of Discocyrtus pectinifemur Mello-Leitão, 1937 (Gonyleptidae) (n = 23) behave differently when in contact with olfactory cues from different sources (rotten prey, non-rotten prey and a control). Using dead crickets in a box covered with a mesh, and recording the time the harvestmen spent in the vicinities of the box, we show that D. pectinifemur detects non-rotten prey and stays longer on it than on the other two treatments. Our results contrast with a previous study on another species, showing that we should not generalize results obtained for one species....

First field record of mangrove crab Ucides cordatus (Crustacea: Decapoda: Ucididae) recruits co-inhabiting burrows of conspecific crabs
Provedor de dados: 103
Autores: Schmidt,Anders Jensen; Diele,Karen.
Recruits of the mangrove crab Ucides cordatus (Linnaeus, 1763), rarely encountered in the field were found co-inhabiting burrows of larger male and female conspecifics in the mangrove forest. They were located in the sediment of the inner walls and burrow plugs. Average carapace width (CW) of the hosting and co-inhabiting crabs was 3.8 ± 0.20 and 0.9 ± 0.03, respectively. As shown by the size-frequency distribution, while most recruits leave the conspecific burrows after reaching 1.0 cm CW, some stay until they reach a size of 2.5 cm CW. The results of this study contribute to a better understanding of recruitment patterns in this ecologically and economically important mangrove crab species. Follow-up studies are however needed to fully determine the role...

First high-altitude record of Bucculatrix mirnae Vargas and Moreira (Lepidoptera, Bucculatricidae) on a newly documented host plant: the importance of host plant distribution for conservation on the western slopes of the Andes mountains of northern Chile
Provedor de dados: 92
Autores: Vargas,Héctor A.; Mundaca,Enrique A.
ABSTRACT Bucculatrix mirnae Vargas and Moreira, 2012 (Lepidoptera, Bucculatricidae) is a micromoth native to the coastal valleys of the Atacama Desert previously known to occur only in the type locality of the Azapa Valley, close to sea level. Its immature stages are associated with the shrub Baccharis salicifolia (Ruiz &amp; Pav.) Pers. (Asteraceae). We report data on the occurrence of B. mirnae found for the first time at 3500 m above sea level on the western slopes of the Andes mountains of northern Chile. In addition, Baccharis alnifolia Meyen &amp; Walp. is recorded as a new host plant for B. mirnae. The implications of this finding for conservation in the arid western slopes of the Andes habitats in northern Chile are discussed.

First host plant record for Strymon davara (Hewitson) (Lepidoptera, Lycaenidae) in the highly human-modified coastal valleys of the Atacama Desert
Provedor de dados: 92
Autores: Vargas,Héctor A.; Duarte,Marcelo.
ABSTRACT Some native plants can survive the disturbances associated with agricultural activities, sometimes being considered weeds and objects of control practices. However, these plants can be very important to support populations of native insects in disturbed habitats. Alternanthera halimifolia (Lam.) Standl. (Amaranthaceae) is locally considered a weed, and here it is reported as the first host plant known for the Neotropical hairstreak Strymon davara (Hewitson, 1868) based on research performed in the coastal valleys of the Atacama Desert of northern Chile. Furthermore, field observations suggest that this is the only host of S. davara in this area. This case provides an example of the importance of a weed in the conservation of local populations of a...

First record in Argentina of a plant-insect association, with interest in biological control
Provedor de dados: 67
Autores: Turienzo,Paola.
The species Chrysolina quadrigemina (Suffrian) (Coleoptera: Chrysomelidae) is recorded for the first time in Argentina, this being also the first record of this genus in the country. Its host plant, Hypericum perforatum L. (Clusiaceae) is native from Asia, Europe and Africa, and has behaved as a strong invader in several countries of the world where the implementation of a biological control program was necessary. The only country in South America that implemented such a control was Chile, in 1953. The arrival of C. quadrigemina to southern Argentina is probably due to natural dispersion from Chile. This record increases the number of Chrysomelidae species in the country.

Autores: Ribeiro,Leandro do Prado; Netto,Alexandre Carlos Menezes; Jochims,Felipe; Haseyama,Kirstern Lica Follman; de Carvalho,Claudio J.B.
ABSTRACT Bermudagrass (Cynodon dactylon cv. Jiggs) is an important food source for dairy cattle in the semi-intensive milk production systems most often used in southern Brazil. Although many insect pests are associated with feed grasses, we report here the first occurrence of the fly Atherigona (Atherigona) reversura Villeneuve, 1936 (Diptera: Muscidae) feeding on bermudagrass in Brazil. This potential pest was observed in April 2015 in three localities (Abelardo Luz, Palmitos, and Videira) in western Santa Catarina, in southern Brazil. The infested plants had senescent and necrotic terminal leaves that reduced plant growth. New growth had to sprout new tillers from basal nodes, which resulted in a reduced plant growth rate.

We provide the first record of breeding of the Ornate Hawk-Eagle (Spizaetus ornatus) for southern Brazil. In September 2005 a nest was found inside the reservoir of the Barra Grande Hydroelectric Power Station, northern Rio Grande do Sul. On the nest there was a nestling around two months old. Based in prey remains collected on the nest, birds were the main item in diet. This is an endangered species in the Atlantic Rain Forest biome in Brazil and the presence of the nest and nestling offer evidence of reproduction in Southern Brazil.

First record of endoparasitism of Pycnogonida in Hydrozoan polyps (Cnidaria) from the Brazilian coast
Provedor de dados: 49
Autores: Bettim,Ariane Lima; Haddad,Maria Angélica.
Despite the relatively high number of recent studies on Cnidaria off the Brazilian coast, we have observed only two records of parasitism on macromedusae and none on polyps. Endoparasitic associations between Pycnogonida larvae and hydroids have been well known since the early 20th century. Protonymph larvae develop inside the gastrovascular cavity of polyps, typically gastrozooids, which are then called gallzooids. This short communication is an unprecedented record of parasitism on the polyps of Brazilian cnidarian fauna. The parasitic association between Pycnogonida Anoplodactylus stictus and a new hydroid species of Podocoryna has been casually detected on the encrusting communities of experimental polyethylene plates installed at the Paranaguá Yacht...

ABSTRACT The widespread cultivation of transgenic soybeans has caused significant changes in the spectrum of Lepidoptera larvae, both in the number of species as well as on their densities in the field. Transgenic crops producing Bacillus thuringiensis (Bt) insecticidal proteins have successfully reduced the incidence of the most common caterpillars infesting soybeans, namely Anticarsia gemmatalis (Lepidoptera: Erebidae) and Chrysodeixis includens (Lepidoptera: Noctuidae). However, lepidopteran species not previously recorded on the crop have been recently found, and are of concern due to the possibility of adaptation to the genetically modified cultivars. The occurrence of Peridroma saucia Hübner (Lepidoptera: Noctuidae) is described for the first time in...

Provedor de dados: 49
Autores: Pérez,Carlos Daniel; Gomes,Paula Braga.
The polychaete Hermodice carunculata is a voracious predator of several benthic organisms and one of the preferential groups in its diet is that of the cnidarians. This note presents the first record of a fireworm preying on the calcified hydroid Millepora alcicornis. The fireworm engulfs the terminal branches of the fire coral and spends several minutes scraping the surface and removing the soft tissues. Despite this being one of the most common calcified hydroids of the Brazilian northern and northeastern regions (and home to a vast associated community), this kind of association had never been recorded. This discovery points to the need of studying such associations because the damage caused by this polychaete is irreversible and depending on the amount...

Incidence of parasitoid Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) was assessed between November 2015 and March 2016, in Letamendi, Febres-Cordero and Tarqui, urban districts of Guayaquil. Highest incidence of parasitism occurred in those regions and seasons of the year with the highest temperatures commensurate with increase of citrus plant shoots. Similar to their host, these parasitoids appear to have established in Ecuador by accident, and were not the result of purposeful introduction. This...

First records of the Crested Black-Tyrant (Knipolegus lophotes, Tyrannidae) in the State of Mato Grosso do Sul, Brazil
Provedor de dados: 49
Autores: Godoi,Maurício Neves; Costacurta,Marco de Barros; Nunes,Alessandro Pacheco; Patrial,Eduardo Weffort; Morante Filho,José Carlos.
The Crested Black-Tyrant (Knipolegus lophotes) is a member of the Tyrannidae family that occurs throughout open areas in central, southeastern and southern Brazil. Although this species occurs in regions that surround the state of Mato Grosso do Sul, there had never been a recorded sighting in the state. Thus, information on its distribution across Brazil's midwestern region is scarce. In this study, we report the first sightings of K. lophotes in Mato Grosso do Sul. These records extend the known distribution range of the species in midwestern Brazil and contribute to expanding knowledge of bird species composition in this region. We believe that the absence of K. lophotes from the lists of bird species recorded in different localities in Mato Grosso do...

First report of black rot of Colocasia esculenta caused by Ceratocystis fimbriata in Brazil
Provedor de dados: 102
Autores: Harrington,Thomas C.; Thorpe,Daniel J.; Marinho,Vera Lucia A.; Furtado,Edson L.
Ceratocystis fimbriata was found sporulating in gray to black discolored areas on edible corms of Colocasia esculenta found in supermarkets in the states of São Paulo, Rio de Janeiro, Bahia, Rondônia and the Distrito Federal. In most cases the corms were grown in the state of São Paulo. The black rot appeared to occur post-harvest. Sequences of rDNA indicated that the Colocasia sp. isolates belong to the Latin American clade of the C. fimbriata complex, but the isolates were more aggressive than isolates from Ficus carica and Mangifera indica, in pseudopetioles of C. esculenta.

ABSTRACT In 2013, soursop trees showing symptoms of root rot were observed in a field in Maceió, state of Alagoas, Brazil. It was isolated Phytophthora sp. which pathogenicity was confirmed in the host seedlings. Morphological and physiological characteristics in carrot-agar modified medium were consistent with Phytophthora nicotianae description. The PCR sequences products obtained with ITS1/ITS4 primers were compared to sequences of ribosomal DNA of Phytophthora species from the GenBank database observing high identity with other P. nicotianae isolates. A phylogenetic tree was performed to compare the isolate with other sequences of P. nicotianae, which clustering has been verified with 99% of bootstrap, confirming the morphophysiological studies.

Provedor de dados: 49
Autores: França,Filipe M.; Korasaki,Vanesca; Louzada,Julio; Vaz-de-Mello,Fernando Z.
This is the first study to address the dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) diversity in intra-Amazonian savannahs in the state of Roraima, Brazil. Our aim was to survey the dung beetle fauna associated with these savannahs (regionally called 'lavrado'), since little is known about the dung beetles from this environment. We conducted three field samples using pitfall traps baited with human dung in savannah areas near the city of Boa Vista during the rainy seasons of 1996, 1997, and 2008. We collected 383 individuals from ten species, wherein six have no previous record in intra-Amazonian savannahs. The most abundant species were Ontherus appendiculatus (Mannerheim, 1829), Canthidium aff. humerale (Germar, 1813), Dichotomius nisus (Olivier,...

Autores: Martins,E.A.N.; Camargo,L.M.
A six-month-old 245 kg male Simmental calf was referred to the Veterinary Hospital in Cuiabá, MT, with closed comminuted diaphyseal fracture in metacarpus. It was given preference to external fixation as means of fracture immobilization, and transcortical pins and fiberglass cast were used. This technique showed effective immobilization of the fracture, less expensive and feasible to be done in the field.

Fixed bin frequencies for the VNTR loci D2S44, D4S139, D5S110, and D8S358 were determined in a Minas Gerais population sample. The data were generated by RFLP analysis of HaeIII-digested genomic DNA and chemiluminescent detection. The four VNTR loci have met Hardy-Weinberg equilibrium, and there was no association of alleles among VNTR loci. The frequency data can be used in forensic analyses and paternity tests to estimate the frequency of a DNA profile in the general Brazilian population.

Flagging a species as threatened: the case of Eptesicus taddeii, an endemic bat from the Brazilian Atlantic Forest
Provedor de dados: 49
Autores: Bernard,Enrico; Nascimento,Jorge Luiz do; Aguiar,Ludmilla Moura de Souza.
The IUCN Red List is an important conservation tool. Although its criteria are used worldwide, in most cases the classification process per se is restricted to a group of experts with restricted or no participation of the general public. This may raise concerns from final Red List users, which, without knowing the data or procedures adopted by the experts, may argue on the outcomes, final classification adopted, or the overall use of the lists. IUCN recommends that all assessments must be backed up by data and justifications, making them as accurate and transparent as possible. We describe here the assessment of Eptesicus taddeii, a bat species endemic to the southern Atlantic Forest of Brazil, indicating how and why the species was flagged as Vulnerable -...

Provedor de dados: 68
Autores: Dellacasa M,Varia A; Figueroa R,Ricardo A; Alvarado O,Sergio A; Schlatter,Roberto P.
We describe the flight behaviour of the Red-backed Hawk (Buteo polyosoma) during summer in Nevados de Chillán, Chile. Flight types most often used were gliding, wind-hovering and soaring (36.7%, 29.4% and 27.8% of the flying time, respectively). Spent time in gliding and wind-hovering peaked at mid-afternoon (17:00-19:00 h). Conversely, soaring was highest between mid-morning (10:00-11:00 h) and mid-day (13:00-14:00 h). Red-backed Hawk individuals appeared to use these flight types in an opportunistically manner using advantageous microclimatic and topographic conditions.

Autores: Silva,Juliana Silvestre; Felfili,Jeanine Maria.
Cerradão vegetation shares many species with savanna and forest areas and is one of the most vulnerable phytophysiognomies in the Cerrado (Brazilian savanna) biome. The floristic composition of the Cerradão Biological Reserve was examined between September/2007 and November/2008. A total of 282 species distributed among 194 genera and 75 families were encountered, demonstrating proportions of 0.91 herbaceous species and 0.54 shrub species for each tree species. Fabaceae, Asteraceae, Rubiaceae, Poaceae, Myrtaceae, Malpighiaceae, and Melastomataceae were the most species-rich families. Fully 72.3% of the species of this dystrophic cerradão were shared by cerrado and forest vegetations, while 60.43% were shared by other cerradão sites, although the largest...

The Pacific white shrimp, Litopenaeus vannamei (Penaeidae), represents about 95% of all Brazilian shrimp production. The Brazilian L. vannamei foundation broodstock was made up of specimens collected from different American Pacific sites, but little information was collected on the genetic structure of the broodstock. We used the fluorescence amplified fragment length polymorphism (fAFLP) method to study the genetic diversity of L. vannamei broodstock lines 03CMF1 and 03CBF1 originally produced by breeder-shrimps imported mainly from Panama and Ecuador, although wild individuals from other localities may also have been used in producing these two lines. Our results showed a total of 93 polymorphic bands ranging from 50 to 500 bp, the mean Nei's genetic...

Foliar phosphorus supply and CO2 assimilation in common bean (Phaseolus vulgaris L.) under water deficit
Provedor de dados: 61
Autores: Santos,Mauro G. dos; Ribeiro,Rafael V.; Teixeira,Marcelo G.; Oliveira,Ricardo F. de; Pimentel,Carlos.
Two common bean cultivars were grown in pots under greenhouse conditions. Plants were submitted to a foliar Pi spray two days before suspending irrigation, what enhanced net CO2 assimilation rate of Ouro Negro cultivar but did not change significantly the photosynthesis of Carioca cultivar under both water deficit and rehydration periods. The results revealed that a foliar Pi spray induced an up-regulation of photosynthesis in common bean under mild water deficit, with this effect being genotype-dependent.

Forced copulation attempt in the Blue-tailed Lizard, Micrablepharus maximiliani (Reinhardt &amp;amp; Luetken, 1862) (Squamata, Gymnophthalmidae) in the Caatinga of Northeastern Brazil
Provedor de dados: 49
Autores: Gogliath,Melissa; Ribeiro,Leonardo Barros; Freire,Eliza Maria Xavier.
Forced copulation is characterized by jerky and rapid movements performed by a female in an apparent attempt to escape from a mounting male. This short communication reports a forced copulation attempt by the gymnophthalmid lizard Micrablepharus maximiliani in a forest enclave inside the Caatinga biome, Tenente Laurentino Cruz municipality, Rio Grande do Norte, Brazil. The rejection behavior of the female consisted of running, pushing and hiding from the mounting male. Although the causes of female mate rejection remain unclear, it may be possible that on this occasion the female M. maximiliani may not have been reproductively active and/or avoided the male deliberately.

Autores: Fabbri,Liliana Teresa; Ploschuk,Edmundo Leonardo; López,María Virginia; Insausti,Pedro; Rua,Gabriel Hugo.
Morphological and physiological responses to freezing were evaluated in two ecotypes of the perennial turfgrass Paspalum vaginatum. Leaf extension rate, number of active meristems, leaf water potential and net photosynthesis were measured on plants of both a commercial cultivar, 'Sea Isle 2000', and a wild ecotype from the Flooding Pampa grasslands of Argentina. Plants were propagated by cloning, cultivated in pots, and examined during 18 consecutive days under two treatments: a non-frozen control treatment (15.5±7 ºC) and a frozen treatment with two stages: Stage 1 with four hours of freezing stress for 10 nights (-5ºC), and Stage 2 with 12 hours of freezing stress for eight nights (five nights at -5ºC and three nights at -8ºC). After these treatments,...

ABSTRACT  Planting new types of tangerines is an interesting alternative for Brazilian citrus growers due to the increasing domestic market. Thus, the aim of this study was to evaluate a less exploited variety of tangerine, the Fremont. The physics and chemical quality of the fruit and juice (mass, peel color, juice yield, acidity, soluble solids and maturation index) was evaluated, followed by sensory testing for ranking of difference and preference to Nules clementine and Ponkan tangerine varieties. The Fremont tangerine produces fruits that meet the standards required by the Brazilian consumer market, with an appropriate mass for sale of the fresh fruit, a suitable juice yield, and early to mid-season maturation. Furthermore, et the preference, together...

Frequency of B cells in normal mice which recognize self proteins
Provedor de dados: 56
The mechanism whereby the immune system avoids self-aggression is one of the central issues of Immunology. The discovery of natural autoantibodies, mainly of IgM isotype, and of idiotypic interactions between antibodies indicates that elements of the immune system interact with self constituents and with themselves. Results of studies with soluble antibodies have indicated that the pool of circulating IgM represents the end result of a highly selective process of B cells activation and differentiation by self proteins resulting in the formation of a network. The objective of the present work was to determine the frequency of self-reacting B cells in normal mice. We were able to detect B cells that recognize self proteins present in extracts of different...

Autores: Vargas,A.E.; Marrero,A.R.; Salzano,F.M.; Bortolini,M.C.; Chies,J.A.B.
A sample of 103 randomly chosen healthy individuals from Alegrete, RS, Brazil, was tested for the CCR5delta32 allele, which is known to influence susceptibility to HIV-1 infection. The CCR5delta32 allele was identified by PCR amplification using specific primers flanking the region of deletion, followed by electrophoresis on a 3% agarose gel. The data obtained were compared to those reported for other populations and interpreted in terms of Brazilian history. The individuals studied came from a highly admixed population. Most of them were identified as white (N = 59), while blacks and browns (mulattoes) were N = 13 and N = 31, respectively. The observed frequencies, considering the white, black and brown samples (6.8, 3.8, and 6.4%, respectively), suggest...

Frequency of leucism in a colony of Anoura geoffroyi (Chiroptera: Phyllostomidae) roosting in a ferruginous cave in Brazil
Provedor de dados: 49
Autores: Reis,Aline da Silva; Zampaulo,Robson de Almeida; Talamoni,Sônia Aparecida.
Abstract: We provide the first report of the frequency of leucism for a species of Neotropical bat. Leucism is an anomaly of the skin pigmentation of an animal that manifests itself as the total or partial loss of the natural color of the species, and can affect part of or the entire body. During a study involving capture and marking individuals of a population of A. geoffroyi residing in a cave in the Brazilian state of Minas Gerais, seven individuals with some degree of depigmentation were recorded out of 616 individuals marked, for a frequency of 1.1%. Since leucism is due to recessive gene expression, these findings may indicate that the population is isolated and possesses a high level of endogamy. Factors that may be responsible for this condition in...

Abstract  In Brazil there are still few studies on the post-harvest quality of low-chill blueberry cultivars, which have been recently introduced in the country. ‘Snowchaser’ blueberries were evaluated during a six-day storage period regarding fruit physical and chemical properties, and its antioxidant capacity. During fruit storage there was an increased weight loss and maintenance of some skin color properties such as luminosity (L*) and b*, whereas the values of parameter a* decreased and chroma (C) values increased. The levels of anthocyanins and flavonoids in the pulp increased, as well as the antioxidant activity. Maximum fruit shelf life at room temperature was six days without reduction on the antioxidant activity along the period, which is...

A better understanding of dendritic cell (DC) involvement in responses to haptenic drugs is needed, because it represents a possible approach to the development of an in vitro test, which could identify patients prone to drug allergies. There are two main DC subsets: plasmacytoid DC (pDC) and myeloid DC (mDC). β-lactams form hapten-carrier conjugates and may provide a suitable model to study DC behavior in drug allergy reactions. It has been demonstrated that drugs interact differently with DC in drug allergic and non-allergic patients, but there are no studies regarding these subsets. Our aim was to assess the functional changes of mDC and pDC harvested from an amoxicillin-hypersensitive 32-year-old woman who experienced a severe maculopapular exanthema...

Autores: Serrão,F.V.; Foerster,B.; Spada,S.; Morales,M.M.B.; Monteiro-Pedro,V.; Tannús,A.; Salvini,T.F.
The present study evaluated functional changes of quadriceps muscle after injury induced by eccentric exercise. Maximal isometric torque of quadriceps and the surface electromyography (root mean square, RMS, and median frequency, MDF) of the vastus medialis oblique (VMO) and vastus lateralis (VL) muscles were examined before, immediately after and during the first 7 days after injury. Serum creatine kinase (CK) levels and magnetic resonance imaging (MRI) were used to identify muscle injury. The subject was used as her own control and percent refers to pre-injury data. Experiments were carried out with a sedentary 23-year-old female. Injury was induced by 4 bouts of 15 maximal isokinetic eccentric contractions (angular velocity of 5º/s; range of motion from...

Functional evidence that the central renin-angiotensin system plays a role in the pressor response induced by central injection of carbachol
Provedor de dados: 56
We investigated the effects of losartan, an AT1-receptor blocker, and ramipril, a converting enzyme inhibitor, on the pressor response induced by angiotensin II (ANG II) and carbachol (a cholinergic receptor agonist). Male Holtzman rats (250-300 g) with a stainless steel cannula implanted into the lateral ventricle (LV) were used. The injection of losartan (50 nmol/1 &amp;amp;micro;l) into the LV blocked the pressor response induced by ANG II (12 ng/1 &amp;amp;micro;l) and carbachol (2 nmol/1 &amp;amp;micro;l). After injection of ANG II and carbachol into the LV, mean arterial pressure (MAP) increased to 31 &amp;amp;plusmn; 1 and 28 &amp;amp;plusmn; 2 mmHg, respectively. Previous injection of losartan abolished the increase in MAP induced by ANG II and...

Provedor de dados: 39
Autores: Fernandes,Elio Gomes; Valério,Henrique Maia; Duarte,Karen Luiza Rodrigues; Capuchinho,Lauany Matos de Novais; Fagundes,Marcílio.
ABSTRACT Copaifera oblongifolia is a recurrent plant species in degraded areas yet there is little information about its seed biology and interactions with fungi. The aims of this study were to identify the fungal community (endophytic and non-endophytic) associated with C. oblongifolia seeds and to test the effects of these different fungal species on germination. In general, germination of C. oblongifolia seeds was high (about 85 %), initiating four days after sowing and continuing for a total of 20 days. External asepsis with sodium hypochlorite did not influence germinability of C. oblongifolia. Seed infestation with Aspergillus niger, A. flavus, Mucor sp. and Rhizopus stolonifer did not affect the time required for germination, however, infection with...

Autores: Berto,A.G.A.; Oba,S.M.; Michelacci,Y.M.; Sampaio,L.O.
In many tumors, the amount of chondroitin sulfate in the extracellular matrix has been shown to be elevated when compared to the corresponding normal tissue. Nevertheless, the degree of chondroitin sulfate increase varies widely. In order to investigate a possible correlation between the amount of chondroitin sulfate and tumor size, several individual specimens of human leiomyoma, a benign uterine tumor, were analyzed. The glycosaminoglycans from eight tumors were extracted and compared with those from the respective adjacent normal myometrium. The main glycosaminoglycan found in normal myometrium was dermatan sulfate, with small amounts of chondroitin sulfate and heparan sulfate. In leiomyoma, both dermatan sulfate and chondroitin sulfate were detected...

Abstract In Argentina, five galling species of the family Cecidosidae (Lepidoptera), including Cecidoses eremita Curtis and Eucecidoses minutanus Brèthes, have been cited. This note reports a preliminary study of their galls in "molles" (Schinus longifolius (Lindl.) Speg.) of Magdalena (Buenos Aires, Argentina). In April 2013, galls of C. eremita and E. minutanus were censused in randomly selected "molles". In April and December 2013, randomly selected galls were then collected and transported to our laboratory in hermetic bags, and conserved at -18 ºC until examination. Maximum diameter and wall thickness of collected galls were measured. About 84% of the observed "molles" (103/123) had galls of C. eremita and/or E. minutanus. The median of galls per tree...

Gap effect and reaction time distribution: simple vs choice manual responses
Provedor de dados: 56
Autores: Machado-Pinheiro,W.; Gawryszewski,L.G.; Ribeiro-do-Valle,L.E.
It is well known that saccadic reaction times (SRT) are reduced when the target is preceded by the offset of the fixation point (FP) - the gap effect. Some authors have proposed that the FP offset also allows the saccadic system to generate a separate population of SRT, the express saccades. Nevertheless, there is no agreement as to whether the gap effect and express responses are also present for manual reaction times (MRT). We tested the gap effect and the MRT distribution in two different conditions, i.e., simple and choice MRT. In the choice MRT condition, subjects need to identify the side of the stimulus and to select the appropriate response, while in the simple MRT these stages are not necessary. We report that the gap effect was present in both...

Gel mobility shift scanning of pectin-inducible promoter from Penicillium griseoroseum reveals the involvement of a CCAAT element in the expression of a polygalacturonase gene
Provedor de dados: 74
Autores: Ribon,Andréa de O.B.; Ribeiro,João Batista; Gonçalves,Daniel B.; Queiroz,Marisa V. de; Araújo,Elza F. de.
Previous reports have described pgg2, a polygalacturonase-encoding gene of Penicillium griseoroseum, as an attractive model for transcriptional regulation studies, due to its high expression throughout several in vitro growth conditions, even in the presence of non-inducing sugars such as sucrose. A search for regulatory motifs in the 5' upstream regulatory sequence of pgg2 identified a putative CCAAT box that could justify this expression profile. This element, located 270 bp upstream of the translational start codon, was tested as binding target for regulatory proteins. Analysis of a 170 bp promoter fragment by electrophoretic mobility shift assay (EMSA) with nuclear extracts prepared from mycelia grown in pectin-containing culture medium revealed a high...

The creatine kinase-isoenzyme MB (CK-MB) mass assay is one of the laboratory tests used for the diagnosis of myocardial infarction. It is recommended, however, that reference limits should take gender and race into account. In the present study, we analyzed the plasma CK-MB mass and troponin levels of 244 healthy volunteers without a personal history of coronary artery disease and with no chronic diseases, muscular trauma or hypothyroidism, and not taking statins. The tests were performed with commercial kits, CK-MB mass turbo kit and Troponin I turbo kit, using the Immulite 1000 analyzer from Siemens Healthcare Diagnostic. The values were separated according to gender and showed significant differences by the Mann-Whitney test. Mean (± SD) CK-MB mass...

In breast cancer patients submitted to neoadjuvant chemotherapy (4 cycles of doxorubicin and cyclophosphamide, AC), expression of groups of three genes (gene trio signatures) could distinguish responsive from non-responsive tumors, as demonstrated by cDNA microarray profiling in a previous study by our group. In the current study, we determined if the expression of the same genes would retain the predictive strength, when analyzed by a more accessible technique (real-time RT-PCR). We evaluated 28 samples already analyzed by cDNA microarray, as a technical validation procedure, and 14 tumors, as an independent biological validation set. All patients received neoadjuvant chemotherapy (4 AC). Among five trio combinations previously identified, defined by nine...

Autores: Guidetti-Gonzalez,Simone; Freitas-Astúa,Juliana; Amaral,Alexandre Morais do; Martins,Natália F.; Mehta,Angela; Silva,Marilia Santos; Carrer,Helaine.
Plants are continuously exposed to pathogen attack, but successful infection is rare because they protect themselves against pathogens using a wide range of response mechanisms. One of them is the hypersensitive response (HR), which is a form of cell death often associated with plant resistance to pathogen infection to prevent the spreadsebpg@cnpq.br sebpg@cnpq.br of the potential pathogen from infected to uninfected tissues. Cell death is activated by recognition of pathogen-derived molecules by the resistance (R) gene products, and is associated with the massive accumulation of reactive oxygen species (ROS), salicylic acid (SA), and other pro-death signals such as nitric oxide (NO). The analysis of the citrus EST (CitEST) database revealed the presence...

The cauliflower (Brassica oleracea var. botrytis) is an annual vegetable cultivated in Southern and Southwestern Brazil with limited production in the Northeast and Centralwest. A variety of Chinese kale, "kaai laan" or "gaillon" (Brassica oleracea var. alboglabra), produces seeds at high temperatures and therefore can do so in North and Northeastern Brazil. Gaillon and cauliflower were crossed 55 times using 10 gaillon plants as mothers and 4 cauliflower plants as pollen donors. From these crosses, in the F2 generation, 612 plants with inflorescence like gaillon and 48 plants with inflorescence like cauliflower were obtained, in a proportion similar to 15:1, implying that 2 pairs of genes entered into formation of the cauliflower inflorescence type.

ABSTRACT Global dissemination of mcr-like genes represents a serious threat to public health since it jeopardizes the effectiveness of colistin, an antibiotic used as a last-resort treatment against highly antibiotic-resistant bacteria. In 2017, a mcr-1-positive isolate of Escherichia coli was found in Chile for the first time. Herein we report the genetic features of this strain (UCO-457) by whole-genome sequencing (WGS) and conjugation experiments. The UCO-457 strain belonged to ST4204 and carried a 285 kb IncI2-type plasmid containing the mcr-1 gene. Moreover, this plasmid was transferred by conjugation to an E. coli J53 strain at high frequency. The isolate harbored the cma, iroN, and iss virulence genes and did carry resistance genes to...

Autores: Médici,K.C.; Barry,A.F.; Alfieri,A.F.; Alfieri,A.A.
Group B rotaviruses (RV-B) were first identified in piglet feces, being later associated with diarrhea in humans, cattle, lambs, and rats. In human beings, the virus was only described in China, India, and Bangladesh, especially infecting adults. Only a few studies concerning molecular analysis of the RV-B NSP2 gene have been conducted, and porcine RV-B has not been characterized. In the present study, three porcine wild-type RV-B strains from piglet stool samples collected from Brazilian pig herds were used for analysis. PAGE results were inconclusive for those samples, but specific amplicons of the RV-B NSP2 gene (segment 8) were obtained in a semi-nested PCR assay. The three porcine RV-B strains showed the highest nucleotide identity with the human WH1...

Abstract Scinax (Anura: Hylidae) is a species-rich genus of amphibians (113 spp.), divided into five species groups by morphological features. Cladistic analyses however revealed only two monophyletic clades in these groups: Scinax catharinae and Scinax ruber. Most species from the S. catharinae clade are found in Atlantic rainforest, except for Scinax canastrensis,S. centralis, S. luizotavioi, S. machadoi,S. pombali and S. skaios. In the present work, specimens of Scinax collected in Chapada dos Guimarães, central Brazil, were morphologically compatible with species from theS. catharinae group. On the other hand, genetic analysis based on mitochondrial (16S and 12S) and nuclear (rhodopsin) sequences revealed a nucleotide divergence of 6 to 20% between...

Autores: PRABHU,ANNE S.; FILIPPI,MARTA C.; ARAUJO,LEILA G.; FARIA,JOSIAS C.
An epidemic of rice (Oryza sativa) blast occurred on cultivars Epagri 108 and 109 in the municipalities of Lagoa da Confusão and Duerê in the State of Tocantins, during the rice-growing season 1998-99. DNA fingerprinting and virulence phenotype analysis were utilized to determine the diversity of Pyricularia grisea isolates collected from these cultivars in one epidemic year. Rep-PCR analysis of isolates was done by using two primer sequences from Pot2. Two distinct fingerprint groups or lineages were identified among 53 isolates collected from nine different commercial fields. The virulence pattern of isolates retrieved from these two cultivars was analyzed in artificial inoculation tests utilizing 32 genotypes in the greenhouse. A dendrogram constructed...

The genetic characterization of dengue virus type 3 (DEN-3) strains isolated from autochthonous cases in the State of Rio de Janeiro, Brazil, in 2001 is presented. Restriction site-specific (RSS)-PCR performed on 22 strains classified the Brazilian DEN-3 viruses as subtype C, a subtype that contains viruses from Sri Lanka, India, Africa and recent isolates from Central America. Nucleic acid sequencing (positions 278 to 2550) of one DEN-3 strain confirmed the origin of these strains, since genotype III - classified by sequencing - and RSS-PCR subtype C are correlated. This genetic subtype has been associated with hemorrhagic dengue epidemics and the information provided here could be useful to implement appropriate prevention and control measures.

Genetic control of characters associated with bean golden mosaic geminivirus resistance in Phaseolus vulgaris L.
Provedor de dados: 54
Bean golden mosaic is the most important viral disease of the bean crop (Phaseolus vulgaris L.) in Latin America. The genetics of resistance to a Brazilian strain of bean golden mosaic virus (BGMV), was studied in a 4 x 4 diallel cross without reciprocals, among the parental genotypes DOR 303, EMGOPA 201 Ouro, Carnaval, and Redlands Greenleaf C. Seedlings of the four parents, six F1 hybrids, 12 backcrosses, and F2 generations for each combination were inoculated on the eighth day after sowing by exposure to a viruliferous whitefly (Bemisia tabaci Genn.) population for 24 h, in a glasshouse, prior to transplantation to field conditions. The full set of two parents, F1, F2 and respective backcrosses for each combination was considered to be a family. Data...

Autores: Camargo,Carlos Eduardo de Oliveira; Ferreira Filho,Antonio Wilson Penteado.
Wheat cultivars should have long primary roots to allow good crop establishment, considering the short crop establishment season (April) in the State of São Paulo, Brazil, where the occurrence of water stress is frequent. This paper demonstrates the control and type of inheritance of the primary root growth trait. Crosses were made between genotypes, BH-1146 and KAUZ "S"/IAC-24 M4 with strong and reduced primary root growth, respectively. F2 and F3 generation seeds from these crosses and F2 generation seeds from the backcrosses of both parents were also obtained. Seedlings from these genotypes plus the parentals were evaluated in relation to primary root growth in complete nutrient solutions containing 3.875 mg L-1 phosphorus, at pH 4.0 and a temperature...

Genetic divergence among populations and accessions of the spineless peach palm from Pampa Hermosa landrace used in the heart-of-palm agribusiness in Brazil
Provedor de dados: 74
Autores: Alves-Pereira,Alessandro; Clement,Charles R.; Picanço-Rodrigues,Doriane.
Although originally domesticated for its fruit, exploitation of the peach palm (Bactris gasipaes Kunth) in the production of gourmet heart-of-palm has also become an important activity, hence the need for improved material for large-scale production, on employing the Pampa Hermosa landrace as the seed source. In this study 11 microsatellite markers were used to evaluate genetic divergence among 96 elite plants representing four populations of spineless peach palm from the above cited source. Genetic variability was high (H T = 0.82). The low levels of divergence [F ST (0.023), G ST' (0.005)] and the high number of migrants (Nm -3.8 to 52.2) indicated significant interpopulation gene flow. Some of the plants presented high levels of genetic divergence, but...

Genetic divergence of a newly documented population of the cecidogenous micromoth Eugnosta azapaensis Vargas &amp;amp; Moreira (Lepidoptera: Tortricidae) in the Atacama Desert of northern Chile
Provedor de dados: 92
Autores: Escobar-Suárez,Scott; Huanca-Mamani,Wilson; Vargas,Héctor A.
Abstract Eugnosta azapaensis Vargas and Moreira, 2015 (Lepidoptera: Tortricidae) is a micromoth native to the Atacama Desert whose larvae induce fusiform galls in shoots of Baccharis salicifolia (Ruiz &amp; Pav.) Pers. (Asteraceae). The presence of this cecidogenous tortricid was previously recorded only from the type locality, the Azapa Valley, Arica Province, northern Chile. However, fusiform galls on shoots of B. salicifolia were recently found in Chaca, another coastal valley of the Atacama Desert. The adults obtained from these galls were preliminarily identified as E. azapaensis based on morphology. Subsequently, to assess an additional source of evidence for the taxonomic identification of E. azapaensis in this new locality, sequences of the DNA...

Autores: Santos,Silvia Correa; Carvalho,Raquel dos Santos; Davide,Livia Maria Chamma.
Abstract  The genus Anacardium presents nine species, of these, three have sub-bush size, common in the Cerrado of the Center-West of Brazil. The objective of this work was to evaluate the genetic variability of the species, collected in eleven provenances, using RAPD markers. Genomic DNA from 122 accessions was extracted and amplified with 25 decamer primers. The results indicated polymorphism, ranging from 77.71% to 96.18%. The distribution of genetic diversity among and within populations shows that 27.14% of the variability is found between populations and 37.44% within the populations, suggesting the existence of genetic variability that may be related to the reproductive strategies adopted by the species throughout its evolution. The index of...

Provedor de dados: 74
Autores: Sofia,Silvia H.; Paula,Francine M. de; Santos,Aline M. dos; Almeida,Fernanda S.; Sodré,Leda M.K.
Random amplified polymorphic DNA (RAPD) markers were used to analyze the genetic structure of Eufriesea violacea populations in three fragments (85.47, 832.58 and 2800 ha) of Atlantic rainforest located in the north of the Brazilian state of Paraná. A total of twelve primers produced 206 loci, of which 129 were polymorphic (95% criterion). The proportions of polymorphic loci in each population ranged from 57.28% to 59.2%, revealing very similar levels of genetic variability in the groups of bees from each fragment. Unbiased genetic distances between groups ranged from 0.0171 to 0.0284, the smallest genetic distance occurring between bees from the two larger fragments. These results suggest that the E. violacea populations from the three fragments have...

Genetic variability and efficiency of DNA microsatellite markers for paternity testing in horse breeds from the Brazilian Marajó archipelago
Provedor de dados: 74
Autores: Reis,Sávio P.; Gonçalves,Evonnildo C.; Silva,Artur; Schneider,Maria P.C.
In this study, 15 microsatellite DNA loci used in comparative tests by the International Society for Animal Genetics were applied to the evaluation of genetic diversity and management, and the efficiency of paternity testing in Marajoara horses and Puruca ponies from the Marajó Archipelago. Based on the genotyping of 93 animals, mean allelic diversity was estimated as 9.14 and 7.00 for the Marajoara and Puruca breeds, respectively. While these values are similar to those recorded in most European breeds, mean levels of heterozygosity were much lower (Marajoara 49%, Puruca 40%), probably as a result of high levels of inbreeding in the Marajó populations. The mean informative polymorphic content of this 15-marker system was over 50% in both breeds, and was...

Genetically modified corn on fall armyworm and earwig populations under field conditions
Provedor de dados: 65
Autores: Frizzas,Marina Regina; Silveira Neto,Sinval; Oliveira,Charles Martins de; Omoto,Celso.
The effects of corn MON810 on the Spodoptera frugiperda (J.E. Smith) and the earwig Doru luteipes (Scudder) were tested under field conditions in Brazil. Results from MON810 corn fields were compared with those fields of conventional corn with and without the application of insecticides in four harvests in the region of Barretos, SP. It was assessed the damage to S. frugiperda via direct counts of the number of fall armyworms and adults and nymphs of the predator D. luteipes on corn plants. The rate of S. frugiperda damage and the average numbers of larvae (large and small) were lower in the MON810 corn field relative to the control plot. There were no differences (P&gt;0.05) between treatments regarding the predator abundance in corn plants. The second...

Genetics of resistance to soybean cyst nematode, Heterodera glycines ichione (Race 3), in a brazilian soybean population
Provedor de dados: 74
Autores: Mauro,Antonio Orlando; Oliveira,Antonio Luiz de; Mauro,Sonia Marli Z.
A study was made of the genetics of resistance to the soybean cyst nematode, race 3, in a population derived from crosses between the Brazilian soybean genotypes BR 90-4722 and FT-Cristalina. Crosses between the two parents were made, the F1 and F2 generations were obtained and the population was analyzed for the number of cysts found in each plant of each generation as well as the type of reaction to the nematode. The results showed that resistance to the cyst nematode in this soybean population is of a qualitative nature and conditioned by three genes, one dominant and two recessives. The heritability of the character was very high (0.96), with minimum environmental effect, which means that this population is suitable for the development of soybean...

Genome size of three Brazilian flies from the Sciaridae family
Provedor de dados: 74
Autores: Saccuti,Cecília Ferreira; Soares,Maria Albertina de Miranda; Falco,José Ricardo Penteado; Fernandez,Maria Aparecida.
We determined the genome size of the Brazilian sciarid flies Bradysia hygida, Rhynchosciara americana and Trichosia pubescens (Diptera: Sciaridae) using absorbance measurements of Feulgen-stained nuclei belonging to these species (and chicken erythrocytes as a standard) to calculate the amount of DNA in picograms (pg) and the number of base pairs (bp), or C-value, for each of these species. The C-values were: 3 x 10(8) bp (0.31 pg) for B. hygida; 3.6 x 10(8) bp (0.37 pg) for R. americana; and 1 x 10(9) bp (1.03 pg) for T. pubescens. The sciarids investigated in this work had considerably higher C-values than the average for previously described dipteran species, including D. melanogaster.

Genomic characterization of Brazilian hepatitis C virus genotypes 1a and 1b
Provedor de dados: 56
Parts of 5' non-coding (5' NC) and of E1 envelope regions of the hepatitis C virus (HCV) genome were amplified from sera of 26 Brazilian anti-HCV antibody-positive patients using the reverse transcription-polymerase chain reaction (RT-PCR). Fourteen samples were PCR positive with primers from the 5' NC region and 8 of them were also positive with primers from the E1 region. A genomic segment of 176 bp from the E1 region of 7 isolates was directly sequenced from PCR products. The sequences were compared with those of HCV strains isolated in other countries and the Brazilian isolates were classified by phylogenetic analysis into genotypes 1a and 1b. This could have a clinical importance since it has been shown that individuals infected with type 1 viruses...

The availability of the genome sequence of the bacterial plant pathogen Xylella fastidiosa, the causal agent of citrus variegated chlorosis, is accelerating important investigations concerning its pathogenicity. Plant vessel occlusion is critical for symptom development. The objective of the present study was to search for information that would help to explain the adhesion of X. fastidiosa cells to the xylem. Scanning electron microscopy revealed that adhesion may occur without the fastidium gum, an exopolysaccharide produced by X. fastidiosa, and X-ray microanalysis demonstrated the presence of elemental sulfur both in cells grown in vitro and in cells found inside plant vessels, indicating that the sulfur signal is generated by the pathogen surface....

Cystic fibrosis (CF) is caused by CFTR (cystic fibrosis transmembrane conductance regulator) gene mutations. We ascertained five patients with a novel complex CFTR allele, with two mutations, H939R and H949L, inherited in cis in the same exon of CFTR gene, and one different mutation per patient inherited in trans in a wide population of 289 Caucasian CF subjects from South Italy. The genotype-phenotype relationship in patients bearing this complex allele was investigated. The two associated mutations were related to classical severe CF phenotypes.

Methicillin-resistant Staphylococcus aureus (MRSA) is a major agent of hospital infections worldwide. In Brazil, a multiresistant MRSA lineage (ST239-SCCmecIIIA), the so-called Brazilian epidemic clone (BEC), has predominated in all regions. However, an increase in nosocomial infections caused by non-multiresistant MRSA clones has recently been observed. In the present study, 45 clinical isolates of MRSA obtained from a university hospital located in Natal city, Brazil, were identified by standard laboratory methods and molecularly characterized using staphylococcal chromosome cassette mec (SCCmec) typing and pulsed-field gel electrophoresis. Antimicrobial susceptibility testing was carried out using CLSI methods. The MRSA isolates studied displayed a...

Autores: Sales,Raul F.D.; Andrade,Maria J.M. de; Jorge,Jaqueiuto da S.; Kolodiuk,Miguel F.; Ribeiro,Matheus M.; Freire,Eliza M.X.
The Neotropical lizard Mabuya agmosticha Rodrigues, 2000 is a habitat-specialist of thorny bromeliads in rocky outcrops of northeastern Brazil. Its distribution in the Caatinga Domain is most likely relictual. In recent years, new surveys conducted in northeastern Brazil have revealed new records of the species in the Caatinga and also in the Atlantic Forest Domain. In this study, we add four new records for M. agmosticha, extending its known geographic range in the states of Rio Grande do Norte and Paraíba. In addition, we investigated the potential geographical distribution of the species using ecological niche modeling (ENM), which combines the available occurrence records with environmental variables. Our model revealed a continuous range of areas with...

Autores: Bittencourt,Mário Lúcio de Carvalho; Dias,Denise Cunha Fernandes dos Santos; Dias,Luiz Antônio dos Santos; Araújo,Eduardo Fontes.
The osmotic conditioning or priming is considered a promising technique to speed up germination and to improve seed performance. Four seed lots of asparagus, Mary Washington cultivar, were primed at 25°C for seven or 14 days using PEG 6000 at -1.0 or -1.2 MPa, or sea water at -3.3 MPa; or for three days in distilled water. The physiological quality of the seeds was evaluated by standard germination, first count germination, speed of seedling emergence, and germination percentage and seedling fresh and dry weights after controlled deterioration test. Primed seeds presented higher germination speed, independently of their initial physiological quality. Beneficial effects of priming on germination and vigour were more expressive in the seed lot of low...

Argyrophilic grain disease (AGD) is a progressive neurodegenerative disease of the human brain that has never been associated to a particular gene locus. In the present study, we report the results of a CNV investigation in 29 individuals whose anatomopathologic investigation of the brain showed AGD. Rare CNVs were identified in six patients (21%), in particular a 40 kb deletion at 17p13.2 encompassing the CTNS gene. Homozygote mutations in CTNS are known to cause cystinosis, a disorder characterized by the intralysosomal accumulation of cystine in all tissues. We present the first CNV results in individuals presenting AGD and a possible candidate gene implicated in the disorder.

Autores: Valois,Marcely; Tinôco,Ricardo; Chia,Gilson; Vaz-de-Mello,Fernando; Grossi,Paschoal; Silva,Fernando.
ABSTRACT The oil palm is an economically important crop cultivated in the North of Brazil. Damage caused by insects is one of the main causes of reduced productivity for the oil palm. Before this research, only the beetles of the family Curculionidae were considered to be oil palm pests in Brazil. However, for the first time, we report on the damage caused by a giant rhinoceros beetle to oil palm plantations in Pará, Brazil. The beetle was identified as Golofa claviger (Linnaeus, 1771), which has a single record in Brazil (Pará) but is widely distributed in South America. The species occurs in an unprecedentedly high abundance of local specimens. The attacks are concentrated on the central cluster of young palms. Feeding behavior is identified as the main...

OBJECTIVE: In order to evaluate the potential zoonotic transmission of Giardia duodenalis, isolates from humans and dogs in the Northwestern region of the São Paulo State, Brazil were characterized based on the β-giardin gene. METHODS: The samples were analyzed by sequencing of the Nested-PCR products. RESULTS: The A1 and A2 subgenotypes were detected in human and dogs. Cysts of assemblage B, C and D have not been found in any isolates studied. CONCLUSIONS: These results are consistent with the view that giardiasis in the largest endemic region of the Brazil should not be seen as a single entity.

Ginkgo biloba leaf extract (EGb 761) enhances catalepsy induced by haloperidol and L-nitroarginine in mice
Provedor de dados: 56
Autores: Fontana,L.; Souza,A.S.; Del Bel,E.A.; Oliveira,R.M.W. de.
Ginkgo biloba extract EGb 761 has been reported to have therapeutic effects which have been attributed to anti-oxidant and free radical-scavenging activities, including a direct action on nitric oxide production. L G-nitro-arginine (L-NOARG), a nitric oxide synthase inhibitor, and haloperidol, a drug that blocks dopamine receptors, are both known to induce catalepsy in rodents. Nitric oxide has been shown to influence dopaminergic transmission in the striatum. The purpose of the present study was to evaluate the effect of the extract obtained from leaves of Ginkgo biloba tree EGb 761 on catalepsy induced by haloperidol or by L-NOARG. Albino Swiss mice (35-45 g, N = 8-12) received by gavage a single or repeated oral dose (twice a day for 4 days) of EGb 761...

Glass pipette-carbon fiber microelectrodes for evoked potential recordings
Provedor de dados: 56
Autores: Moraes,M.F.D.; Garcia-Cairasco,N.
Current methods for recording field potentials with tungsten electrodes make it virtually impossible to use the same recording electrode also as a lesioning electrode, for example for histological confirmation of the recorded site, because the lesioning procedure usually wears off the tungsten tip. Therefore, the electrode would have to be replaced after each lesioning procedure, which is a very high cost solution to the problem. We present here a low cost, easy to make, high quality glass pipette-carbon fiber microelectrode that shows resistive, signal/noise and electrochemical coupling advantages over tungsten electrodes. Also, currently used carbon fiber microelectrodes often show problems with electrical continuity, especially regarding electrochemical...

Provedor de dados: 56
Autores: Luque,A.; Shimizu,M.H.M.; Andrade,L.; Sanches,T.R.; Seguro,A.C.
Mechanical ventilation has been associated with organ failure in patients with acute respiratory distress syndrome. The present study examines the effects of tidal volume (V T) on renal function using two V T values (8 and 27 mL/kg) in anesthetized, paralyzed and mechanically ventilated male Wistar rats. Animals were randomized into two groups of 6 rats each: V T8 (V T, 8 mL/kg; 61.50 ± 0.92 breaths/min; positive end-expiratory pressure, 3.0 cmH2O; peak airway pressure (PAW), 11.8 ± 2.0 cmH2O), and V T27 (V T, 27 mL/kg; 33.60 ± 1.56 breaths/min; positive end-expiratory pressure, none, and PAW, 22.7 ± 4.0 cmH2O). Throughout the experiment, mean PAW remained comparable between the two groups (6.33 ± 0.21 vs 6.50 ± 0.22 cmH2O). For rats in the V T27 group,...

Glucocorticoids, master modulators of the thymic catecholaminergic system?
Provedor de dados: 56
Autores: Pilipović,I.; Kosec,D.; Radojević,K.; Perišić,M.; Pešić,V.; Stojić-Vukanić,Z.; Leposavi,G.
There is evidence that the major mediators of stress, i.e., catecholamines and glucocorticoids, play an important role in modulating thymopoiesis and consequently immune responses. Furthermore, there are data suggesting that glucocorticoids influence catecholamine action. Therefore, to assess the putative relevance of glucocorticoid-catecholamine interplay in the modulation of thymopoiesis we analyzed thymocyte differentiation/maturation in non-adrenalectomized and andrenalectomized rats subjected to treatment with propranolol (0.4 mg·100 g body weight-1·day-1) for 4 days. The effects of β-adrenoceptor blockade on thymopoiesis in non-adrenalectomized rats differed not only quantitatively but also qualitatively from those in adrenalectomized rats. In...

Glutamatergic transmission in the nucleus tractus solitarii: from server to peripherals in the cardiovascular information superhighway
Provedor de dados: 56
Afferent nerves carrying signals from mechanoreceptors in the aortic arch and carotid sinus terminate predominantly in the nucleus tractus solitarii (NTS). Signal transduction and neurotransmission in the NTS are critical for central cardiovascular reflex control, but little was known about either until the late 1970's. None of the numerous neuroactive chemicals found in the NTS had met strict criteria as a neurotransmitter in the baroreflex arc until data suggested that the excitatory amino acid L-glutamate (GLU) might be released from baroreceptor afferent terminals in the NTS. In anesthetized animals microinjection into the NTS of GLU, which can be demonstrated in terminals in the NTS, produces cardiovascular responses like those seen with activation of...

Great unexpected differences between two populations of the intertidal crab Neohelice granulata inhabiting close but contrasting habitats (Crustacea: Decapoda: Brachyura)
Provedor de dados: 103
Autores: Spivak,Eduardo D.; Bas,Claudia C.; Luppi,Tomás A.
ABSTRACT Two populations of the Southwestern Atlantic burrowing crab, Neohelice granulata (Dana, 1851), are separated by only 190 km. They inhabit bays that drain into a Patagonian gulf in the southernmost limit of the geographical distribution of the species: San Antonio Bay (SAO) and San José Gulf (RSJ). The population from SAO has been extensively studied, whereas that of RSJ has not. The main goal of this study is to compare the ecological and habitat characteristics of the two populations, based on samples collected on successive days during the middle of the reproductive season of the crab. The substrate of SAO is composed of a high proportion of gravel and scarce organic matter, whereas the substrate of RSJ presents twice as much silt and clay, and...

Green turtles (Chelonia mydas) foraging at Arvoredo Island in Southern Brazil: genetic characterization and mixed stock analysis through mtDNA control region haplotypes
Provedor de dados: 74
Autores: Proietti,Maíra Carneiro; Lara-Ruiz,Paula; Reisser,Júlia Wiener; Pinto,Luciano da Silva; Dellagostin,Odir Antonio; Marins,Luis Fernando.
We analyzed mtDNA control region sequences of green turtles (Chelonia mydas) from Arvoredo Island, a foraging ground in southern Brazil, and identified eight haplotypes. Of these, CM-A8 (64%) and CM-A5 (22%) were dominant, the remainder presenting low frequencies (&lt; 5%). Haplotype (h) and nucleotide ( π) diversities were 0.5570 ± 0.0697 and 0.0021 ± 0.0016, respectively. Exact tests of differentiation and AMOVA ΦST pairwise values between the study area and eight other Atlantic foraging grounds revealed significant differences in most areas, except Ubatuba and Rocas/Noronha, in Brazil (p &gt; 0.05). Mixed Stock Analysis, incorporating eleven Atlantic and one Mediterranean rookery as possible sources of individuals, indicated Ascension and Aves islands...

ABSTRACT  Yellow passion fruit grafting on other Passiflora spp. may be an alternative technique for the production under biotic stresses, especially soil-borne diseases. This study evaluated the survival of yellow passion fruit to fusariosis grafted onto P. edulis, P. alata, P. gibertii and P. cincinnata, in the field in Cruz das Almas, State of Bahia, Brazil. Horticultural performance was evaluated as plant growth, flowering and fruit set up to 13 months after transplanting. The apical cleft hipocotyledonar grafting was used. Survival analysis to fusariosis was based on the detection of typical visual symptoms. Grafting in species of wild passifloras did not influence on the stem diameter or fruit set of the yellow passion fruit, even though the...

Provedor de dados: 74
Autores: Gomes,Marcus Vinícius de Matos; Santos,Sílvio Avelino dos; Ramos,Ester Silveira.
Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth disorder of complex and heterogeneous etiology involving alterations in genomic imprinting. The cause of isolated hemihyperplasia (IHH) is unknown but might be due to partial or incomplete expression of BWS because both these conditions share predisposition for the same types of neoplasias. We investigated the methylation pattern of the putative imprinting control region H19DMR using peripheral blood from 12 patients, six with clinical features of BWS and six with IHH. All the patients had normal karyotypes and paternal uniparental disomy (UPD) was excluded in 10 informative cases. The normal H19DMR methylation pattern was found in eight informative patients, indicating that H19DMR methylation...

Hawksbill turtles visit moustached barbers: cleaning symbiosis between eretmochelys imbricata and the shrimp stenopus hispidus
Provedor de dados: 49
Autores: Sazima,Ivan; Grossman,Alice; Sazima,Cristina.
This seems to be the first record of cleaning symbiosis between marine turtles and shrimps. During their foraging on the reef flat, the turtles regularly visited and posed at the stations. The same stations were visited by a few species of reef fishes, which posed and were cleaned by the shrimps. We suggest that cleaning symbiosis between turtles and shrimps is widespread and went unrecognised due to the superficial resemblance between a resting turtle and a posing and cleaned one. Additionally, we submit a putative origin for the cleaning symbiosis between marine turtles and cleaner shrimps following a few simple behavioural steps.

Hb Köln [a2b298(FG5) val-met] identified by DNA analysis in a Brazilian family
Provedor de dados: 54
Autores: Miranda,Silvia R.P.; Fonseca,Silvana F.; Figueiredo,Maria S.; Yamamoto,Myoko; Grotto,Helena Z.W.; Saad,Sara T.O.; Costa,Fernando F.
Hb Köln was identified by DNA analysis in a Brazilian patient. A four-year old Brazilian female, with jaundice since birth, presented an abnormal band, between A2 and S, in hemoglobin electrophoresis on a cellulose acetate membrane, and a band with electrophoretic migration similar to Hb C on agar gel. Thermic instability and isopropanol precipitation tests were positive. Heinz bodies were observed in the patient’s peripheral blood. Sequencing of the three exons of the &lt;FONT FACE="Symbol"&gt;b&lt;/font&gt; globin gene detected a transition from G to A in the first position of codon 98. This alteration does not create or abolish any known restriction site. In this case, confirmation of the mutation was accomplished by allele-specific oligonucleotide...

Autores: Dell'Aglio,Denise Dalbosco; Toma,Tiago Shizen Pacheco; Muelbert,Adriane Esquivel; Sacco,Anne Gomes; Tozetti,Alexandro Marques.
Anti-predator mechanisms in snakes are diverse and complex, including mimetic behavior. Some snakes triangulate their head, probably mimicking other more dangerous snakes. However, there is a lack of studies that demonstrate the effectiveness of this behavior with natural predators. The aim of this study was to verify, using artificial snakes, if snakes with triangular heads are less susceptible to attack by predators, and if predatory attack is targeted to the head of serpents. Artificial snakes were systematically arranged on a road border. The rate of attacked models was 48.71%. Number of attacks on models with rounded head was significantly higher than in models with triangular head. There was a significant difference between the places of attack on...

Heat storage rate and acute fatigue in rats
Provedor de dados: 56
Autores: Rodrigues,L.O.C.; Oliveira,A.; Lima,N.R.V.; Machado-Moreira,C.A.
Thermal environmental stress can anticipate acute fatigue during exercise at a fixed intensity (%VO2max). Controversy exists about whether this anticipation is caused by the absolute internal temperature (Tint, ºC), by the heat storage rate (HSR, cal/min) or by both mechanisms. The aim of the present study was to study acute fatigue (total exercise time, TET) during thermal stress by determining Tint and HSR from abdominal temperature. Thermal environmental stress was controlled in an environmental chamber and determined as wet bulb globe temperature (ºC), with three environmental temperatures being studied: cold (18ºC), thermoneutral (23.1ºC) or hot (29.4ºC). Six untrained male Wistar rats weighing 260-360 g were used. The animals were submitted to...

Em setembro de 2003, em Manaus, Amazonas, foram observadas manchas foliares, muito semelhantes àquelas de sigatoka-negra causada por Mycosphaerella fijiensis em folhas de Heliconia psittacorum. Efetuou-se o isolamento do patógeno e, para o teste de patogenicidade, foi utilizada a técnica de inoculação cruzada com os isolados de H. psittacorum e de bananeira (Musa spp.) da cv. Prata Anã. Em ambas as espécies o teste foi positivo. Com o auxílio do microscópio óptico, da literatura disponível e dos testes de patogenicidade, confirmou-se que H. psittacorum é hospedeira de M. fijiensis, sendo este o primeiro relato da ocorrência de M. fijiensis em helicônias.

Provedor de dados: 56
Autores: Perícole,F.V.; Alves,M.A.V.R.; Saad,S.T.O.; Costa,F.F.
Patients with chronic renal insufficiency (CRI) have reduced hemoglobin levels, mostly as a result of decreased kidney production of erythropoietin, but the relation between renal insufficiency and the magnitude of hemoglobin reduction has not been well defined. Hereditary hemochromatosis is an inherited disorder of iron metabolism. The importance of the association of hemochromatosis with treatment for anemia among patients with CRI has not been well described. We analyzed the frequency of the C282Y and H63D mutations in the HFE gene in 201 Brazilian individuals with CRI undergoing hemodialysis. The analysis of the effects of HFE mutations on iron metabolism and anemia with biochemical parameters was possible in 118 patients of this study (hemoglobin,...

Autores: Franco,C.R.C.; Rocha,H.A.O.; Trindade,E.S.; Santos,I.A.N.; Leite,E.L.; Veiga,S.S.; Nader,H.B.; Dietrich,C.P.
We have examined the role of cell surface glycosaminoglycans in cell division: adhesion and proliferation of Chinese hamster ovary (CHO) cells. We used both wild-type (CHO-K1) cells and a mutant (CHO-745) which is deficient in the synthesis of proteoglycans due to lack of activity of xylosyl transferase. Using different amounts of wild-type and mutant cells, little adhesion was observed in the presence of laminin and type I collagen. However, when fibronectin or vitronectin was used as substrate, there was an enhancement in the adhesion of wild-type and mutant cells. Only CHO-K1 cells showed a time-dependent adhesion on type IV collagen. These results suggest that the two cell lines present different adhesive profiles. Several lines of experimental...

We infected NIH germ-free female mice with Helicobacter trogontum, a recently described intestinal bacterium of rats, in order to study the lesions it induced in the liver of this host. Fifteen mice were challenged with a single dose of H. trogontum (test group) and killed 6, 12 and 18 months after inoculation (5 animals/group). Nine animals were challenged with 0.85% saline alone (control group) and killed at the same times. Fragments from the liver, cecum and colon were obtained for microbiologic and histologic examination. Stool samples were also collected. H. trogontum was detected in the cecum, colon and/or stool samples of all test mice. As expected, the bacterium was not isolated from any specimen obtained from the control animals. On the other...

Um jabuti (Geochelone carbonaria) de 30 anos de idade foi encaminhado ao setor de patologia para exame post mortem. À necropsia, foi observada ascite acentuada. O fígado apresentava-se diminuído de volume e com vários nódulos firmes entre 0.3 e 1.0 cm de diâmetro distribuídos por todo o órgão. À microscopia, esses nódulos eram constituídos externamente por espessa camada de tecido conjuntivo fibroso envolvendo hepatócitos dilatados e vacuolizados na sua porção central. A cirrose conseqüente à lipidose hepática foi provavelmente causada por níveis baixos de proteína na dieta.

Abstract The six-banded armadillo (Euphractus sexcinctus) stands out among wild mammals due to the rare occurrence of spontaneous metabolic diseases. When altered, the liver, which is important in metabolism, may trigger a dysfunctional cascade, leading to hepatic steatosis. Here we describe a case of hepatic steatosis in a six-banded armadillo living in captivity. The female specimen was captured and donated to the Federal University of Piaui under SISBIO authorization nº53303. The animal was first referred for a veterinary clinical evaluation, and then euthanized following the ethical standards of the Federal Council of Veterinary Medicine. At the start of the dissection, the abdominal cavity was accessed and sections of all ex situ liver lobes, spleen...

ABSTRACTIn coinfected HBV/HCV patients, HBV replication is usually suppressed by HCV over the time. No study to date has evaluated the HBV viremia in long-term follow-up after HCV treatment in hemodialysis patients with HBV/HCV coinfection. This study aimed to assess the evolution of HBV viremia after HCV treatment in this special population. Ten hemodialysis patients with HBV/HCV coinfection with dominant HCV infection (HBV lower than 2000 IU/mL) and significant fibrosis were treated with interferon-alpha 3 MU 3×/week for 12 months and could be followed for at least 36 months after HCV treatment. Six cases of HBV reactivation (60%) during follow-up were observed and 5/6 had been successfully treated for HCV. Patients with HBV reactivation received...

Abstract To assess the prevalence of hepatitis C virus infection among men who have sex with men (MSM) in Central Brazil, a cross-sectional study was conducted in the City of Goiânia, Central Brazil, using Respondent-Driven Sampling (RDS). All serum samples were tested for anti-HCV and also for alanine aminotransferase (ALT). Anti-HCV positive samples and/or those with elevated ALT were tested for HCV RNA and genotyped. Of the 522 participants, four were found to be anti-HCV positive, and one was also HCV RNA positive (active HCV infection). Elevated ALT was found in 14 individuals. Of these, one showed evidence of acute HCV infection (HCV RNA positive and anti-HCV negative). Therefore, five MSM were positive for either anti-HCV and/or HCV RNA, giving a...

Hepatitis C virus core antigen assay: can we think beyond convention in resource limited settings?
Provedor de dados: 55
Autores: Chakravarti,Anita; Chauhan,Mayank S.; Dogra,Gaurav; Banerjee,Sayantan.
ABSTRACT Hepatitis C virus infects over 15 million patients from India and 2.86 million from Brazil. Detection of anti-hepatitis C virus antibodies has limited sensitivity during acute phase: the pre-seroconversion window period. Hepatitis C virus-RNA detection techniques are used to overcome this shortfall, but are costly and unavailable widely in developing countries. Estimation of hepatitis C virus core-antigen, a protein with highly conserved sequence, by enzyme-immunoassays is an economic and simpler alternative to RNA detection. This study was conducted in Delhi, involving 300 acute and chronic liver disease patients, tested for anti-hepatitis C virus 3rd-generation ELISA, hepatitis C virus core-antigen-ELISA and hepatitis C virus-RNA reverse...

Autores: Barbosa,V.S.; Silva,N.A. da; Martins,R.M.B.
Many extrahepatic manifestations, including rheumatic diseases, have been reported to be associated with hepatitis C virus (HCV) infection. In order to investigate the prevalence of HCV infection among patients with rheumatic diseases, in the present study we interviewed 367 patients and tested their blood samples for HCV antibodies (anti-HCV) by an enzyme-linked immunosorbent assay. Anti-HCV-reactive samples were retested for confirmation by a line immunoassay and also for HCV RNA detection by the polymerase chain reaction. HCV RNA-positive samples were genotyped by INNO-LIPA. An overall HCV infection prevalence of 1.9% (7/367) was found. Of the 7 HCV-infected patients, 4 had systemic lupus erythematosus and 3 rheumatoid arthritis, resulting in positivity...

Autores: Zandoná,Carla; Novaes,Tanara G.; Mehta,Yeshwant R.; Schuster,Ivan; Teixeira,Eliria A.; Cunha,Hélio.
A ramulose do algodoeiro (Gossypium hirsutum) causada por Colletotrichum gossypii var. cephalosporioides é responsável por danos apreciáveis no rendimento de algodão. O patógeno ataca toda a parte aérea das plantas provocando manchas nas folhas e no colmo, e superbrotamento da planta. Plantas severamente infetadas normalmente mostram nanismo. Devido a carência de informação sobre o mecanismo de resistência, o processo de produção de novas cultivares com resistência a ramulose é algo prejudicado. O objetivo do presente trabalho foi compreender o mecanismo de herança a ramulose em duas cultivares resistentes (BRS ANTARES e IAC 23) quando cruzadas com uma cultivar suscetível (STO 474).

HERBASPIRILLUM-LIKE BACTERIA IN BANANA PLANTS
Provedor de dados: 58
Autores: Weber,Olmar B.; Cruz,Leonardo M.; Baldani,José I.; Döbereiner,Johanna.
Diazotrophic bacteria isolated from banana plants were characterized by morphological and physiological aspects. Three different groups of these plant-bacteria could be established. Two of them showed similarity to species of the Herbaspirillum genus. The third one was different because used only a few carbon substrates and produced water diffusible compounds that fluoresced under UV light. All three bacterial groups were thin rods with mono or bipolar flagella, presented negative reaction in Gram stain, showed catalase activity, were able to reduce nitrate and grew better in semi-solid JNFb medium at 31ºC. The nitrogenase activity was detected in semi-solid N-free JNFb medium and expressed higher values when pH ranged from 6.5 to 7.0 (groups I and II) and...

Autores: Albuquerque,I.R.L.; Queiroz,K.C.S.; Alves,L.G.; Santos,E.A.; Leite,E.L.; Rocha,H.A.O.
Fucan is a term used to denote a family of sulfated L-fucose-rich polysaccharides which are present in the extracellular matrix of brown seaweed and in the egg jelly coat of sea urchins. Plant fucans have several biological activities, including anticoagulant and antithrombotic, related to the structural and chemical composition of polysaccharides. We have extracted sulfated polysaccharides from the brown seaweed Dictyota menstrualis by proteolytic digestion, followed by separation into 5 fractions by sequential acetone precipitation. Gel electrophoresis using 0.05 M 1,3-diaminopropane-acetate buffer, pH 9.0, stained with 0.1% toluidine blue, showed the presence of sulfated polysaccharides in all fractions. The chemical analyses demonstrated that all...

Heteroptera as vectors of plant pathogens
Provedor de dados: 82
Autores: Mitchell,Paula L.
The ability of piercing-sucking insects to transmit plant disease is closely linked to feeding mode and target tissue. The true bugs (Heteroptera) are generally considered to be of minimal importance as vectors of plant pathogens, although they share similar feeding behaviors with homopterans. Modes of feeding in Heteroptera include "lacerate-and-flush", intracellular penetration to vascular tissue, and an osmotic pump mechanism to acquire cell contents without penetrating the cell membrane. The relationship between heteropteran taxonomy, feeding mode, and the type of pathogens transmitted is explored through a literature survey of feeding behavior and vectoring capability. Transmission by true bugs of fungal pathogens, bacteria, viruses, phytoplasmas, and...

Hiding in plain sight: an evolutionary approach to the South American Zika outbreak and its future consequences
Provedor de dados: 103
Autores: Apari,Péter; Bajer,Katalin; Brooks,Daniel R.; Molnár,Orsolya.
ABSTRACT Emerging Infectious Diseases (EID) pose a world-wide health and socio-economic threat. Accelerating climate change and globalization are exposing unforeseen ways that pathogens cope with their surroundings. The 2015 Zika virus (ZIKV) outbreak was an example of expansion into previously inaccessible fitness spaces, causing a sudden epidemic. Recent studies indicating the subsequent decrease in symptomatic cases means the virus is in remission, currently poses little threat, and therefore can be ignored. We present an evolutionary scenario derived from the Stockholm Paradigm, of oscillating phases of expansion and isolation, accompanied by changes in transmission, persistence, virulence, and pathology. Chief among these is the likelihood that...

Autores: Buassi,N.
This study evaluates the influence of different concentrations of calcium on blood pressure of normotensive rats. Four groups of Wistar rats (A, B, C and D) had free access to modified isocaloric and isoproteic diets containing 0.2, 0.5, 2 and 4 g% calcium as calcium carbonate for a period of 30 days. Systolic and diastolic arterial blood pressures were monitored in awake rats by the indirect tail cuff method using a Physiograph equipped with transducers and preamplifiers. Body weight and length and food intake were monitored. Under the conditions of the present experiment, the systolic and diastolic arterial blood pressures of group D rats fed a diet containing 4 g% calcium were significantly (P&amp;lt;0.05) lower compared to rats of the other groups.

High frequency of the CCR5delta32 variant among individuals from an admixed Brazilian population with sickle cell anemia
Provedor de dados: 56
Autores: Chies,J.A.B.; Hutz,M.H.
Homozygous sickle cell disease (SCD) has a wide spectrum of clinical manifestations. In Brazil, the main cause of death of individuals with SCD is recurrent infection. The CCR5delta32 allele, which confers relative resistance to macrophage-tropic HIV virus infection, probably has reached its frequency and world distribution due to other pathogens that target macrophage in European populations. In the present investigation a relatively higher prevalence (5.1%) of the CCR5delta32 allele was identified, by PCR amplification using specific primers, in 79 SCD patients when compared to healthy controls (1.3%) with the same ethnic background (Afro-Brazilians). Based on a hypothesis that considers SCD as a chronic inflammatory condition, and since the CCR5...

Abstract Brazil is one of the 22 countries that concentrates 80% of global tuberculosis cases concomitantly to a large number of hepatitis C carriers and some epidemiological risk scenarios are coincident for both diseases. We analyzed tuberculosis cases that occurred during α-interferon-based therapy for hepatitis C in reference centers in Brazil between 2001 and 2012 and reviewed their medical records. Eighteen tuberculosis cases were observed in patients submitted to hepatitis C α-interferon-based therapy. All patients were human immunodeficiency virus-negative. Nine patients (50%) had extra-pulmonary tuberculosis; 15 (83%) showed significant liver fibrosis. Hepatitis C treatment was discontinued in 12 patients (67%) due to tuberculosis reactivation and...

High levels of serum mannose-binding lectin are associated with the severity of clinical signs of leptospirosis
Provedor de dados: 56
Autores: Miranda,K.A.; Vasconcelos,L.R.S.; Coelho,L.C.B.B.; Lima Filho,J.L.; Cavalcanti,M.S.M.; Moura,P.
The clinical heterogeneity observed in leptospirosis may be associated with host factors or bacteria virulence. Human serum mannose-binding lectin (MBL) recognizes many pathogens, and low levels of this lectin are associated with susceptibility to infection. MBL is also implicated in the modulation of the inflammatory process. We determined the levels of serum MBL during leptospirosis infection. A double-antibody sandwich ELISA was used to detect the immunoreactive serum MBL. The ELISA plates were coated with monoclonal antibody to MBL and bound MBL or recombinant human MBL were detected by rabbit anti-human MBL serum. HRPO-conjugated goat anti-rabbit antibody was used for detection of the reaction. Two groups of patients seen at referral hospitals in...

Abstract  In Brazil, the main cultivated passion fruit species is Passiflora edulis, which is affected by Fusarium soil fungus. P. mucronata species stands out because it presents resistance to this fungus, being thus an alternative rootstock to yellow passion fruit. Therefore, the aim of this study was to evaluate the anatomy of mini-grafting by top cleft grafting and simple English type grafting, using shoot tips of adult P. edulis plants in clonal rootstocks of P. mucronata. When the rootstocks reached approximately 2.5 mm in diameter and 20 cm in height, grafting was carried out with Parafilm® tape fasteners and silicone clip. At the end of 60 days, histological analysis of the grafting region was performed to verify the formation of the scarring...

Histomorphometric and functional studies of the rat thyroid throughout the estrous cycle
Provedor de dados: 45
Autores: Serakides,R.; Nunes,V.A; Nascimento,E.F.; Serra,G.V.
The influence of the estrous cycle on the thyroid gland was studied. Twenty one five-to-seven-month-old Wistar female rats were divided according to the stage of the estrous cycle in two groups: metaestrus-diestrus and proestrus-estrus. After gross inspection, the thyroids were weighed, sampled, and processed for staining with hematoxilyn-eosin. Seric concentrations of total T4, free T4, total T3, TSH, progesterone, and estradiol were measured. The values of estradiol were significantly higher in the proestrus-estrus stage. However, no significant differences in the plasmatic concentrations of progesterone, free T4, total T4 and TSH throughout the cycle were found. The results of the morphometric study of the thyroid did not indicate any significant...

In order to assess the molecular epidemiology of HIV-1 in two neighboring cities located near the epicenter of the HIV-1 epidemics in Brazil (Santos and São Paulo), we investigated 83 HIV-1 strains obtained from samples collected in 1995 from intravenous drug users. The V3 through V5 region of the envelope of gp 120 was analyzed by heteroduplex mobility analysis. Of the 95 samples, 12 (12.6%) were PCR negative (6 samples from each group); low DNA concentration was the reason for non-amplification in half of these cases. Of the 42 typed cases from São Paulo, 34 (81%, 95% confidence limits 74.9 to 87.0%) were B and 8 (19%, 95% confidence limits 12.9 to 25.0%) were F, whereas of the 41 typed cases from Santos, 39 (95%, 95% confidence limits 91.6 to 98.4%)...

HLA-B*5701 frequency in Chilean HIV-infected patients and in general population
Provedor de dados: 55
Autores: Poggi,Helena; Vera,Alejandra; Lagos,Marcela; Solari,Sandra; Rodríguez P,Luis; Pérez,Carlos M.
It has been demonstrated that HLA-B*5701 screening reduces the risk for hypersensitivity reaction to abacavir in HIV-infected patients. Since B*5701 prevalence varies among different populations, it is important to determine the carrier frequency prior to its use for the screening of HIV-infected patients.The aim of this study was to determine HLA-B*5701 carrier frequency in Chilean general population and HIV-infected patients referred for B*5701 typing. For that purpose 300 blood bank donors and 492 abacavir-naïve HIV-infected patients from Chile were screened for B*5701 by a sequence specific primer PCR.We detected 14/300 (4.7%) B*57-positive individuals in the Chilean general population, 11 (3.7%) were B*5701 positive, and 3 (1%) had another subtype.All...

HLA-DQA1 allele typing by nonisotopic PCR-LIS-SSCP
Provedor de dados: 56
Autores: Abba,M.C.; Gómez,M.A.; Golijow,C.D.
In the present study we used a simple and reliable method for HLA-DQA1 allele typing based on the single-stranded conformation polymorphism (SSCP) properties of DNA molecules obtained by PCR. The technique consists of PCR amplification of a DNA fragment comprising the second exon of the HLA-DQA1 gene, amplicon denaturation using a low ionic strength solution (LIS), and electrophoresis on a small native polyacrylamide gel, followed by a rapid silver staining procedure. In order to validate the technique and to obtain the allele patterns for the DQA1 gene, 50 cervical samples were typed using this methodology and the commercial Amplitype® HLA DQA1 Amplification and Typing kit. All the alleles detected with the kit were characterized by the LIS-SSCP approach....

Provedor de dados: 94
Autores: MARTIGNAGO,MIRELI; MARTINS,RAFAEL; HARTER-MARQUES,BIRGIT.
ABSTRACT  The production of fruits and seeds of many crops is increased when bees visit their flowers pollinating them. The aim of this study was to evaluate the effect of different pollination treatments on ‘Bordô’ grapevine (Vitis labrusca L.) fruit quantity and quality. Quantitative and qualitative fruit production parameters of plants visited by Apis mellifera L., manually self- and cross-pollinated plants and plants without pollination were analyzed and compared. Fruit production was high for all treatments and all fruits presented four seeds per fruit, on average, confirming that this grape cultivar is autogamous. However, fruit set after spontaneous self-pollination was statistically lower than that of all other treatments, and pollination by A....

Hormone replacement therapy (HRT) reduces cardiovascular risks, although the initiation of therapy may be associated with transient adverse ischemic and thrombotic events. Antibodies against heat shock protein (Hsp) and oxidized low density lipoprotein (LDL) have been found in atherosclerotic lesions and plasma of patients with coronary artery disease and may play an important role in the pathogenesis of atherosclerosis. The aim of the present study was to assess the effects of HRT on the immune response by measuring plasma levels of antibodies against Hsp 65 and LDL with a low and high degree of copper-mediated oxidative modification of 20 postmenopausal women before and 90 days after receiving orally 0.625 mg equine conjugate estrogen plus 2.5 mg...

The skin and mucous membranes of healthy subjects are colonized by strains of Staphylococcus epidermidis showing a high diversity of genomic DNA polymorphisms. Prolonged hospitalization and the use of invasive procedures promote changes in the microbiota with subsequent colonization by hospital strains. We report here a patient with prolonged hospitalization due to chronic pancreatitis who was treated with multiple antibiotics, invasive procedures and abdominal surgery. We studied the dynamics of skin colonization by S. epidermidis leading to the development of catheter-related infections and compared the genotypic profile of clinical and microbiota strains by pulsed field gel electrophoresis.

Abstract In this study, we evaluated trends in hospitalization rates, length of stay and in-hospital mortality in a cohort of HIV-infected patients in Rio de Janeiro, Brazil, from 2007 through 2013. Among the 3991 included patients, 1861 hospitalizations occurred (hospitalization rate of 10.44/100 person-years, 95% confidence interval 9.98–10.93/100 person-years). Hospitalization rates decreased annually (per year incidence rate ratio 0.92, 95% confidence interval 0.89–0.95) as well as length of stay (median of 15 days in 2007 vs. 11 days in 2013, p-value for trend &lt; 0.001), and in-hospital mortality (13.4% in 2007 to 8.1% in 2013, p-value for trend = 0.053).

The effect of temporary host deprivation on the reproduction and survival of Trichogramma kaykai Pinto &amp;amp; Stouthamer was determined by comparing a Wolbachia-infected (thelytokous) and an arrhenotokous line of T. kaykai when reared on Trichoplusia ni Hübner (Lepidoptera: Noctuidae) eggs. The progeny produced by both arrhenotokous and thelytokous females decreased with increasing periods of host deprivation, but arrhenotokous females produced significantly more progeny than thelytokous females regardless of the period of host deprivation (0 to 10 days). They also produced more daughters. Host deprivation did not affect brood size within arrhenotokous or thelytokous lines. However, fewer wasps emerged from hosts parasitized by Wolbachia-infected than...

Provedor de dados: 82
Autores: FERREIRA,SORAIA A.; VASCONCELLOS-NETO,JOÃO.
The grasshopper Cornops aquaticum (Bruner) lives permanently on aquatic macrophytes in floodplains of tropical South America. Its host plants and feeding preference were determined by field observations, crop analysis and feeding tests in the laboratory. Macrophytes were sampled and their petioles were examined for potential egg deposition in order to reveal host plant specificity. Sub-samples were dissected in the laboratory and eggs were counted directly whereas the rest of the sample was kept in net-covered water tanks aiming to verify hatching of nymphs. C. aquaticum fed and oviposited on Eichhornia azurea and Pontederia cordata (Pontederiaceae) in the field. Out of 140 fore-guts analyzed from free-living grasshoppers, 75% contained Pontederiaceae...

How are antibodies involved in the protective mechanism of susceptible mice infected with T. cruzi?
Provedor de dados: 56
Autores: Umekita,L.F.; Mota,I.
Host resistance to Trypanosoma cruzi is dependent on both natural and acquired immune responses. During the acute phase of the infection the presence of IFN-&lt;FONT FACE=Symbol&gt;g&lt;/font&gt;, TNF-&lt;FONT FACE=Symbol&gt;a&lt;/font&gt;, IL-12 and GM-CSF has been closely associated with resistance, whereas TGF-ß and IL-10 have been associated with susceptibility. Several investigators have demonstrated that antibodies are responsible for the survival of susceptible animals in the initial phase of infection and for the maintenance of low levels of parasitemia in the chronic phase. However, how this occurs is not yet understood. Our results and other data in the literature support the hypothesis that the protective role of antibodies in the acute phase of...

The fact that the rate of improvement in crop performance has plummeted in a number of important crops is discussed. To revert this situation, in my opinion, a truly interdisciplinary approach should be applied to the breeding process, making use of the vast amount of knowledge recently generated in the areas of genomics, ecophysiology, statistics, bioinformatics, etc. . Moreover, a special emphasis should be put on phenotyping which -in my opinion- is the new bottleneck, considering the increasingly fast pace and continuously decreasing costs of genotypic data generation. In the meanwhile, a...

How much effort should be employed for surveying a low-diversity Amazonian mammal assemblage using line-transects?
Provedor de dados: 103
Autores: Mourthé,Ítalo.
Line-transect surveys are commonly used for sampling large mammals, but estimates of the effort needed to reliably surveying low-diversity assemblages of mammals are scarce. Using data from line-transects and species accumulation curves, I examined whether or not a sampling effort previously suggested to survey mammals elsewhere (ca. 85-100 km) would be satisfactory for surveying a low-diversity assemblage of large mammals in the Rio Negro basin in northern Amazonia. In total, 14 mammals were recorded after an accumulated effort of 690 km walked. The desired threshold of completeness was only achieved in one of six transects after an average effort of 115 km surveyed. Considering the entire landscape (all transects pooled), survey completeness was reached...

Abstract Presarcopenia and sarcopenia were evaluated in HIV-infected individuals and in healthy elderly controls according to the consensus definitions of the European Working Group on Sarcopenia in Older People. Bioelectrical impedance, a hydraulic hand dynamometer, and gait speed were used to evaluate muscle mass, muscle strength, and physical performance, respectively. Adjusted and unadjusted binary logistic regression predicted the risk of sarcopenia. Predictor contribution was assessed by the Wald test. Significance was established at p ≤ 0.05. The HIV-infected group consisted of 33 patients on treatment (42.4% women; mean age 59 ± 7 years; mean BMI 25 ± 6 kg/m2; viral load undetectable in 30 cases).

Abstract Mesenchymal stem cells (MSCs) are known for their important properties involving multilineage differentiation potential., trophic factor secretion and localization along various organs and tissues. On the dark side, MSCs play a distinguished role in tumor microenvironments by differentiating into tumor-associated fibroblasts or supporting tumor growth via distinct mechanisms. Cisplatin (CIS) is a drug widely applied in the treatment of a large number of cancers and is known for its cytotoxic and genotoxic effects, both in vitro and in vivo. Here we assessed the effects of CIS on MSCs and the ovarian cancer cell line OVCAR-3, by MTT and comet assays. Our results demonstrated the resistance of MSCs to cell death and DNA damage induction by CIS,...

Abstract Mucolipidosis II and III (ML II and III) alpha/beta and ML III gamma are lysosomal diseases caused by GlcNAc-1-phosphotransferase deficiency. Previous data indicate that MLII patients have functionally impaired immune system that contributes to predisposition to infections.We evaluated the immunological phenotype of three Brazilian patients with ML III gamma. Our data suggest that the residual activity of GlcNAc-1-phosphotransferase in patients with ML III gamma is enough to allow the targeting of the lysosomal enzymes required for B-cell functions maintenance.

Humpback whale Megaptera novaeangliae (Cetartiodactyla: Balaenopteridae) group sizes in line transect ship surveys: An evaluation of observer errors
Provedor de dados: 103
Autores: Bortolotto,Guilherme A.; Danilewicz,Daniel; Andriolo,Artur; Zerbini,Alexandre N.
ABSTRACT Accurate estimates of group sizes through line transect sampling methods are important to correctly ascertain the abundance of animals that occur in groups. Since the average observed group size is a component of the distance sampling formula, bias in these data leads to biased abundance estimates. This study aimed to evaluate the potential errors in group size estimation during line transect ship surveys to estimate abundances of the humpback whale, Megaptera novaeangliae (Borowski 1781). In a research cruise along the Brazilian coast, an experiment to collect group size information was conducted from two different sighting platforms on the same vessel. Group sizes were recorded by primary observers at first sighting (PO1) and, in some cases,...

Xylanase activity was isolated from crude extracts of Trichoderma harzianum strains C and 4 grown at 28oC in a solid medium containing wheat bran as the carbon source. Enzyme activity was demonstrable in the permeate after ultrafiltration of the crude extracts using an Amicon system. The hydrolysis patterns of different xylans and paper pulps by xylanase activity ranged from xylose, xylobiose and xylotriose to higher xylooligosaccharides. A purified ß-xylosidase from the Trichoderma harzianum strain released xylose, xylobiose and xylotriose from seaweed, deacetylated, oat spelt and birchwood xylans. The purified enzyme was not active against acetylated xylan and catalyzed the hydrolysis of xylooligosaccharides, including xylotriose, xylotetraose and...

Hyperalgesic effect induced by barbiturates, midazolam and ethanol: pharmacological evidence for GABA-A receptor involvement
Provedor de dados: 56
The involvement of GABA-A receptors in the control of nociception was studied using the tail-flick test in rats. Non-hypnotic doses of the barbiturates phenobarbital (5-50 mg/kg), pentobarbital (17-33 mg/kg), and thiopental (7.5-30 mg/kg), of the benzodiazepine midazolam (10 mg/kg) or of ethanol (0.4-1.6 g/kg) administered by the systemic route reduced the latency for the tail-flick response, thus inducing a 'hyperalgesic' state in the animals. In contrast, non-convulsant doses of the GABA-A antagonist picrotoxin (0.12-1.0 mg/kg) administered systemically induced an increase in the latency for the tail-flick response, therefore characterizing an 'antinociceptive' state. Previous picrotoxin (0.12 mg/kg) treatment abolished the hyperalgesic state induced by...

Hypercaloric cafeteria-like diet induced UCP3 gene expression in skeletal muscle is impaired by hypothyroidism
Provedor de dados: 56
Autores: Christoffolete,M.A.; Moriscot,A.S.
The uncoupling protein UCP3 belongs to a family of mitochondrial carriers located in the inner mitochondrial membrane of certain cell types. It is expressed almost exclusively at high levels in skeletal muscle and its physiological role has not been fully determined in this tissue. In the present study we have addressed the possible interaction between a hypercaloric diet and thyroid hormone (T3), which are strong stimulators of UCP3 gene expression in skeletal muscle. Male Wistar rats weighing 180 ± 20 g were rendered hypothyroid by thyroidectomy and the addition of methimazole (0.05%; w/v) to drinking water after surgery. The rats were fed a hypercaloric cafeteria diet (68% carbohydrates, 13% protein and 18% lipids) for 10 days and sacrificed by...

Transposable elements (TE) are major components of eukaryotic genomes and involved in cell regulation and organism evolution. We have analyzed 123,889 expressed sequence tags of the Eucalyptus Genome Project database and found 124 sequences representing 76 TE in 9 groups, of which copia, MuDR and FAR1 groups were the most abundant. The low amount of sequences of TE may reflect the high efficiency of repression of these elements, a process that is called TE silencing. Frequency of groups of TE in Eucalyptus libraries which were prepared with different tissues or physiologic conditions from seedlings or adult plants indicated that developing plants experience the expression of a much wider spectrum of TE groups than that seen in adult plants. These are...

Abstract Cashew, Anacardium occidentale L. (Anacardiaceae), is one of the most important sources of agricultural income in northeastern Brazil, but many of the arthropods associated with the crop have yet to be identified. We describe here for the first time the damage caused by Holopothrips fulvus (Morgan) (Thysanoptera: Phlaeothripidae) to dwarf-cashew trees cultivated in the municipality of Pacajús, Ceará, Brazil. Leaf tissue injuries were caused by the sucking mouthparts of the insect and were characterized by dark necrotic spots on the epidermis that resulted in yellowing, wilting and, ultimately, abscission of the leaves. H. fulvus also fed on developing kernels and pseudofruits producing injuries that manifested in the form of chlorotic specks....

Autores: Marães,V.R.F.S.; Silva,E.; Catai,A.M.; Novais,L.D.; Moura,M.A.S.; Oliveira,L.; Gallo Jr.,L.
The objective of the present study was to characterize the heart rate (HR) patterns of healthy males using the autoregressive integrated moving average (ARIMA) model over a power range assumed to correspond to the anaerobic threshold (AT) during discontinuous dynamic exercise tests (DDET). Nine young (22.3 ± 1.57 years) and 9 middle-aged (MA) volunteers (43.2 ± 3.53 years) performed three DDET on a cycle ergometer. Protocol I: DDET in steps with progressive power increases of 10 W; protocol II: DDET using the same power values as protocol 1, but applied randomly; protocol III: continuous dynamic exercise protocol with ventilatory and metabolic measurements (10 W/min ramp power), for the measurement of ventilatory AT. HR was recorded and stored beat-to-beat...

RESUMO As serpentes vindas da natureza e encaminhadas para centros de reabilitação ou de pesquisa têm uma idade incerta. Na natureza, esses animais, muitas vezes atingem um tamanho corpóreo menor do que os indivíduos cativos devido a uma menor frequência de alimentação. Assim, a idade de uma cobra recém-chegada da natureza é geralmente estimada com base em seu tamanho corpóreo, o qual é comparado com dados em cativeiro. A utilização dos meios de diagnóstico por imagem tem auxiliado a medicina na análise das serpentes em cativeiro, mediante avaliação da estrutura óssea, dos órgãos e de alterações. Este trabalho relata o uso de diagnóstico por imagem (radiografia e ultrassonografia) para identificar a presença de microchips e, consequentemente, estimar a...

Identifying reasons for failure in biomedical research and publishing
Provedor de dados: 56
Autores: Bousfield,D.
The regular assessment of Brazilian scientific output means that individual university departments need to constantly improve the quantity and quality of their scientific output. A significant proportion of this output involves the work of Master’s and Doctoral students, but getting this work published in a suitable journal can often prove to be a challenge. Although students’ lack of fluency in English is a contributing factor, many of the problems observed have an early origin in the formulation of the research problem and its relevance to current research trends in the international literature. In short, more time needs to be spent in the library and less in the laboratory, and more effort needs to be made in teaching students basic research skills such...

Lipase from Fusarium solani FS1 was immobilized by covalent attachment to polyacrylamide beads and onto magnetized Dacron, retaining 12% and 97% of activity, respectively. Lipase was also entrapped within polyacrylamide beads, retaining 53% of activity. Investigations of the kinetic characteristics of the immobilized derivatives using triolein as substrate showed that lipase immobilized onto polyacrilamide beads and Dacron did not follow Michaelis-Menten kinetics.

Immunization by subcutaneous implants of polyester-polyurethane sponges coupled with antigen
Provedor de dados: 56
Autores: Lima,S.L.; Machado,C.B.; Pereira,M.A.C.; Cara,D.C.; Velarde,D.T.; Andrade,S.P.; Gontijo,C.M.
A new protocol is described for immunization of outbred Swiss mice. The procedure is based on subcutaneous implantation of antigen-coupled polyester-polyurethane sponges cut into disks of 10 mm in diameter vs 2 mm in thickness. Antigen coupling was performed by overnight incubation of the sponge with a solution of ovalbumin (Ova) (2 mg/ml) diluted in sodium carbonate buffer, pH 9.6. The amount of ovalbumin that was taken up by the sponge was between 71.4 to 82.5 µg. This was estimated by comparing the Ova absorbance at 280 nm in coating buffer solutions before and after incubation. To compare the efficiency of the proposed method, experimental groups immunized with the antigen in the presence of adjuvants (10 µg in Al(OH)3 or 100 µg in complete Freund's...

Immunodominance: a new hypothesis to explain parasite escape and host/parasite equilibrium leading to the chronic phase of Chagas' disease?
Provedor de dados: 56
Autores: Rodrigues,M.M.; Alencar,B.C.G. de; Claser,C.; Tzelepis,F.
Intense immune responses are observed during human or experimental infection with the digenetic protozoan parasite Trypanosoma cruzi. The reasons why such immune responses are unable to completely eliminate the parasites are unknown. The survival of the parasite leads to a parasite-host equilibrium found during the chronic phase of chagasic infection in most individuals. Parasite persistence is recognized as the most likely cause of the chagasic chronic pathologies. Therefore, a key question in Chagas' disease is to understand how this equilibrium is established and maintained for a long period. Understanding the basis for this equilibrium may lead to new approaches to interventions that could help millions of individuals at risk for infection or who are...

Autores: Atta,A.M.; Sousa,C.P.; Carvalho,E.M.; Sousa-Atta,M.L.B.
Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by intense polyclonal production of autoantibodies and circulating immune complexes. Some reports have associated SLE with a Th2 immune response and allergy. In the present study 21 female patients with SLE were investigated for total IgE and IgE antibodies to dust house aeroallergens by an automated enzyme-linked fluorescent assay, and were also evaluated for antinuclear IgE autoantibodies by a modified indirect immunofluorescence test using HEp-2 cells as antigen substrate. Additionally, immunocapture ELISA was used to investigate serum anti-IgE IgG autoantibodies. Serum IgE above 150 IU/ml, ranging from 152 to 609 IU/ml (median = 394 IU IgE/ml), was observed in 7 of 21 SLE...

Autores: Amaral,J.F.; Foschetti,D.A.; Assis,F.A.; Menezes,J.S.; Vaz,N.M.; Faria,A.M.C.
Most contacts with food protein and microbiota antigens occur at the level of the gut mucosa. In animal models where this natural stimulation is absent, such as germ-free and antigen-free mice, the gut-associated lymphoid tissue (GALT) and systemic immunological activities are underdeveloped. We have shown that food proteins play a critical role in the full development of the immune system. C57BL/6 mice weaned to a diet in which intact proteins are replaced by equivalent amounts of amino acids (Aa diet) have a poorly developed GALT as well as low levels of serum immunoglobulins (total Ig, IgG, and IgA, but not IgM). In the present study, we evaluated whether the introduction of a protein-containing diet in 10 adult Aa-fed C57BL/6 mice could restore their...

Immunological effects of donor lymphocyte infusion in patients with chronic myelogenous leukemia relapsing after bone marrow transplantation
Provedor de dados: 56
Autores: Castro,F.A.; Palma,P.V.B.; Morais,F.R.; Voltarelli,J.C.
Allogeneic bone marrow transplantation (alloBMT) is the only curative therapy for chronic myelogenous leukemia (CML). This success is explained by the delivery of high doses of antineoplastic agents followed by the rescue of marrow function and the induction of graft-versus-leukemia reaction mediated by allogeneic lymphocytes against host tumor cells. This reaction can also be induced by donor lymphocyte infusion (DLI) producing remission in most patients with CML who relapse after alloBMT. The immunological mechanisms involved in DLI therapy are poorly understood. We studied five CML patients in the chronic phase, who received DLI after relapsing from an HLA-identical BMT. Using flow cytometry we evaluated cellular activation and apoptosis, NK...
