A gueroba (Syagrus oleracea Becc.) nas comunidades rurais II: sistema de producao e avaliacao economica. Infoteca-e
AGUIAR, J. L. P. de; ALMEIDA, S. P. de.
A gueroba, guariroba ou gariroba e uma palmeira importante para a populacao do Cerrado, sendo extraido dela um palmito de sabor amargo muito apreciado na culinaria regional. Esse produto e comercializado, geralmente, in natura e sua industrializacao ainda e artesanal. Seu principal mercado localiza-se nos Estados de Goias, Tocantins, Mato Grosso, Mato Grosso do Sul, algumas regoes da Bahia e de Minas Gerais e no Distrito Federal. Com a exploracao predatoria e a acelerada destruicao da vegetacao nativa por meio da expansao da fronteira agricola, a oferta do produto, oriunda do extrativismo, vem sendo reduzida substancialmente. No entanto, tem-se observado o cultivo dessa palmeira em alguns Estados, principalmente em Goias que, em 1999, cultivava 4.499...

A stochastic viability approach to ecosystem-based fisheries management ArchiMer
Doyen, Luc; Thebaud, Olivier; Bene, Christopher; Martinet, V.; Gourguet, S.; Bertignac, Michel; Fifas, Spyros; Blanchard, Fabian.
Academia and management agencies show a growing interest for ecosystem-based fishery management (EBFM). However, the way to operationalize this approach remains challenging. The present paper illustrates how the concepts of stochastic co-viability, which accounts for dynamic complexities, uncertainties, risk and sustainability constraints, can be useful for the implementation of EBFM. In the present case, this concept is used to identify fishing strategies that satisfy both ecological conservation and economic sustainability in a multi-species, multi-fleet context. Economic Viability Analysis (EVA) and the broader Co-Viability Analysis (CVA), are proposed to expand the usual Population Viability Analysis (PVA) and precautionary approach. An illustration is...

Algumas características da reprodução e ontogênese de Epilachna paenulata (Germar) (Coleoptera, Coccinellidae, Epilachninae) Zoologia
Ganho,Norma G.; Marinoni,Renato C..
Epilachna paenulata (Germar, 1824) was reared feeding on pumpkin leaves (Cucurbita pepo Lourt.) in laboratory conditions at temperatures of 20±0,5ºC, relative humidity of 65±0,5% and 12 hour photoperiod. Groups of fecunded and non-fecunded females were studied. The ovarioles showed four developing stages during egg production, morphologically alike for fecunded and non-fecunded females, but differing in the duration time of the stages. Each ovarium has 24 ovarioles on average, less than any other species known into the genus, and all ovarioles are physiologically active at each oviposition. The mean number of ovarioles is lower when compared with the other species of Epilachninae known. Fecunded and non-fecunded females showed a similar preoviposition...

ALT-C, a disintegrin-like Cys-rich protein from Bothrops alternatus, increases skeletal myoblast viability J. Venom. Anim. Toxins incl. Trop. Dis.
Mesquita-Ferrari,RA; Moraes,CK de; Micocci,KC; Selistre-de-Araújo,HS.
ALT-C, an ECD motif (glutamic acid, cysteine, aspartic acid) disintegrin from Bothrops alternatus snake venom, induces α2β1 integrin-mediated signaling and neutrophil chemotaxis. In vitro, in human umbilical vein endothelial cells (HUVEC), ALT-C induces cell proliferation, thus showing an interesting potential for tissue regeneration studies. This work aimed to evaluate the influence of ALT-C in myoblast viability and differentiation. Myoblasts were obtained from hind limb muscles of 3 to 4-day old Wistar rats. The cells were incubated with ALT-C at different concentrations and incubation periods were followed by total RNA isolation. cDNA synthesis and real time polymerase chain reaction (PCR) were performed with primers of myoD as well as of both (slow...

ANÁLISE COMPARATIVA DA VIABILIDADE ECONÔMICA DOS SISTEMAS DE PRODUÇÃO CONVENCIONAL E INTEGRADO DE CAFÉ AgEcon
Pereira, Vanessa da Fonseca; Mendonca, Talles Girardi de; Reis, Bricio dos Santos.
Due to growing consumer demands regarding product quality and the social and environmental aspects of the production process, there is a need to redefine the agricultural productive structure so as to make it sustainable. The Integrated Production System in Coffee (CIP) aims to meet these new requirement standards. The system, however, is still very recent and requires more detailed studies to identify its strengths and weaknesses. Therefore, the objective of this work is to carry out a comparative analysis of the economic viability and the risk associated to the conventional and integrated systems of coffee production in the farm property of São João, in the Coimbra district in Minas Gerais state. The method used was the calculation of the viability and...

Assessment of viability in the bacterial standing stock of the Antarctic sea from the Indian side ArchiMer
Loka Bharathi, Pa; Nair, S; Bd De Souza, Mj; Chandramohan, D.
During the austral summer, we examined the bacterial population along the cruise track extending from 70degrees S and 18degrees E to 30degrees S and 35degrees E. During the cruise, three distinct fractions of the bacterioplankton viz. total count, total direct viable and retrievable counts were simultaneously enumerated in these waters. In the stations south of the convergent region designated as section I the population ranged within 10(8-9) L-1 whereas in the north of the region designated as section 11 they were one order higher and ranged from 10(9-10) L-1. The percentage of viability in the region was high corresponding to the generally high chlorophyll and primary productivity encountered in the eastern Aghulas bank. The study substantiates the...

ATP content and viability of spermatozoa drive variability of fertilization success in the Pacific oyster ( Crassostrea gigas ) ArchiMer
Boulais, Myrina; Soudant, Philippe; Le Goic, Nelly; Quere, Claudie; Boudry, Pierre; Suquet, Marc.
Fertilization of the oocyte is a critical process of sexual reproduction depending among other factors on spermatozoa functionality. Mitochondria participate in many crucial processes for spermatozoa motility and fertilizing ability. The Pacific oyster, Crassostrea gigas, is characterized by a high inter-individual variability of its reproductive success which has been shown to be partially due to the variability of gamete quality. The present study explored spermatozoa characteristics such as: i) relationships among mitochondrial functionality (ATP content, mitochondrial membrane potential (MMP), reactive oxygen species production); sperm viability (percentages of live, dying, and dead); and motility; and ii) their involvement in inter-oyster variability...

COSTA, N. P. da; MESQUITA, C. M.; HENNING, A. A..
A colheita mecanica da soja acarreta perda de sementes que sao deixadas na superficie do solo. Alem disso, os impactos dos mecanismos da colhedeira sobrea semente afetam a sua qualidade fisiologica, de imediato ou de forma gradativa, durante a armazenagem. Visando avaliar a dimensao desses fenomenos, buscou-se determinar os indices de perdas na colheita mecanica e avaliar os efeitos desse processo sobre a qualidade fisiologica das sementes, em tres niveis de umidade. Apos seis meses de armazenamento, foi reavaliada a qualidade fisiologica das amostras e tambem comparados os niveis de infeccao das sementes colhidas manual e mecanicamente. Os dados foram levantados em 41 propriedades das principais regioes produtoras do Estado do Parana. Em cada propriedade,...

Beijerinckia derxii stimulates the viability of non-N2-fixing bacteria in nitrogen-free media BJM
Barbosa,Heloiza R.; Thuler,Daniela Strauss; Shirakawa,Márcia Aiko; Miyasaka,Natália R. S..
The interactions between the nitrogen-fixing microorganism Beijerinckia derxii with two non-diazotrophic bacteria, either Escherichia coli or a facultative sulphur-oxidizing chemolitotroph, were studied in mixed cultures. Direct and indirect contact between B. derxii and E. coli were tested. B. derxii increased CFU numbers and/or maintained the viability of the non-diazotrophic bacteria, but neither growth nor nitrogenase activity of the nitrogen-fixing bacterium were affected by either partner.

DRESCH,DAIANE M.; MASETTO,TATHIANA E.; SCALON,SILVANA P.Q..
The aim of this study was to evaluate the sensitivity of Campomanesia adamantium seeds to desiccation by drying in activated silica gel (fast) and under laboratory conditions (slow). To assess the sensitivity of the seeds to desiccation, we used drying with silica gel and drying under laboratory conditions (25 °C), in order to obtain seeds with moisture content of 45, 35, 30, 25, 20, 15, 10 and 5%. The physiological potential of the seeds after desiccation was evaluated by measuring primary root protrusion, percentage of normal seedlings, germination seed index, seedling length, total seedling dry mass, electrical conductivity and DNA and RNA integrities. The C. adamantium seeds were sensitive to desiccation and to a reduction in moisture content to 21.1%...

Cross-disciplinary approaches for measuring parasitic helminth viability and phenotype Anais da ABC (AABC)
Peak,Emily; Hoffmann,Karl F.
Parasitic worms (helminths) within the Phyla Nematoda and Platyhelminthes are responsible for some of the most debilitating and chronic infectious diseases of human and animal populations across the globe. As no subunit vaccine for any parasitic helminth is close to being developed, the frontline strategy for intervention is administration of therapeutic, anthelmintic drugs. Worryingly, and unsurprising due to co-evolutionary mechanisms, many of these worms are developing resistance to the limited compound classes currently being used. This unfortunate reality has led to a renaissance in next generation anthelmintic discovery within both academic and industrial sectors. However, a major bottleneck in this process is the lack of quantitative methods for...

Cytotoxicity Assessment of a Poly(methyl methacrylate) Synthesized for the Direct Fabrication of Bone Tissues BABT
Linan,Lamia Zuniga; Lima,Nadson Murilo Nascimento; Benatti,Carol; Xavier,Mariana; Rodrigues,Ana A.; Manenti,Flavio; Jardini,Andre; Maciel Filho,Rubens; Gilioli,Rovilson.
ABSTRACT A cytotoxicity study is performed on a poly(methyl methacrylate) polymer (PMMA) to be used for the fabrication of bone tissue by Rapid Prototyping (RP). The solution polymerization is conducted in a pilot plant reactor using more appropriated reagents in consideration of the medical application. Moreover, the polymer is efficiently handled to avoid the side effect of the monomer, reducing the concentration of this specie to 287,731 µg MMA/kg PMMA. The cytotoxicity of the polymer is determined through growth monitoring, adherence and morphology of L-929 cells. Additionally, MTT and LIVE/DEAD tests are performed. The results showed continuous and progressive growth of the cells on the surface of the specimens. Moreover, the material did not...
