37 years of scientific activity in a Biochemistry Department in Brazil: patterns of growth and factors leading to increased productivity Anais da ABC (AABC)
Gomes,Urubatã E.; Oliveira,Diogo L. de; Berti,Luciana C.; Amaral,Olavo; Souza,Diogo O.; Wofchuk,Susana T..
Scientific activity in Brazil has experienced an accelerated growth in the past decades, with an increase in productivity that greatly surpasses the international average. This growth has occurred mostly at the expense of centers of excellence in public universities, which account for the vast majority of the country's scientific output. The aim of this study was to evaluate the production of the Department of Biochemistry of a large public university in southern Brazil (Universidade Federal do Rio Grande do Sul), as well as to identify internal and external policies that have influenced this growing production profile. We have performed a historical analysis of the scientific output of this Department of Biochemistry, which accounts for a considerable...

Antitumor and biochemical effects of Echis coloratus crude venom on Ehrlich ascites carcinoma cells in vivo J. Venom. Anim. Toxins
MADY,E. A..
The search for snake venom antitumor efficacy has attracted the interest of scientists since the beginning of last century. Snake venom possesses a wide spectrum of biological activities. In this study, we evaluated the effect of Echis coloratus crude venom on the evolution of Ehrlich ascites carcinoma cells (EAC). Normal and EAC-bearing mice were treated with 0.2 mg/kg body weight of crude venom. Crude venom was seen to suppress tumor growth by significantly decreasing EAC cell count and cell viability (p<0.01). There was also a significant increase in survival time of the venom-treated tumor-bearing mice (52.3%, p<0.05) in comparison to the non-treated tumor-bearing counterparts. The study of venom effect and/or tumor inoculation on some important...

Assessing the viability of cryopreserved coconut zygotic embryos by electrolytic conductivity and potassium leaching PAB
Gomes-Copeland,Kicia Karinne Pereira; Lédo,Ana da Silva; Almeida,Fabrício Tavares Cunha de; Miranda,Roberta Pereira; Santos,Izulmé Rita Imaculada.
The objective of this work was to adapt the application of electrolytic conductivity and potassium leaching tests to assess the viability of cryopreserved embryos of 'Anão Verde do Brasil de Jiqui' (AVeJBr) coconut. The zygotic embryos were excised, sterilized and subjected to four cryoprotectant treatments combined with three incubation times (12, 16 and 20 hours), totaling 12 treatments. The pre-treatment of mature zygotic embryos of AVeJBr coconut using a cryoprotectant with 1.75 mol L-1 of sucrose + 15% glycerol for 12 and 16 hours promoted lower embryo humidity and increased viability in electrolytic conductivity and potassium leaching tests. Samples with ten embryos are sufficient for electrolytic conductivity analysis in cryopreserved or...

Balneola vulgaris gen. nov., sp nov., a member of the phylum Bacteroidetes from the north-western Mediterranean Sea ArchiMer
Urios, Laurent; Agogue, Hélène; Lesongeur, Francoise; Stackebrandt, Erko; Lebaron, Philippe.
A novel aerobic, Gram-negative bacterium, named 13IX/A01/164(T), was isolated from surface waters in the coastal north-western Mediterranean Sea. Cells were motile, straight rods, 2-5 mu m long and 0-2 mu m wide, and formed orange colonies on marine agar medium. The G+C content of the genomic DNA of strain 13IX/A01/164T was 42 mol%. Phylogenetic analysis of the 16S rRNA gene sequence placed the strain in the phylum Bacteroidetes within the family Crenotrichaceae. On the basis of 16S rRNA gene sequence comparison and physiological and biochemical characteristics, this isolate represents a novel species of a new genus, for which the name Balneola vulgaris gen. nov., sp. nov. is proposed. The type strain of Balneola vulgaris is 13IX/A01/164T (=DSM 17893T=CIP...

Croissance, engraissement et cycle sexuel de Crassostrea gigas dans le Bassin d'Arachon: comparaison des huîtres agées de 1 et 2 ans ArchiMer
Maurer, Daniele; Borel, Michel.
Two-year-old oysters have a physiology which is reproduction-oriented, their maturation occurring synchronously among oysters from the same batch. The importance of the spring accumulation of glycogenated stocks varies through the years and correlates with the growth stage. Glucidic components are quickly used during the month preceding egg-laying and are transformed into lipid stocks for the oocytes. One-year-old oysters develop at different rates, some of them not showing any sign of maturation and the percentage of laying individuals varies through the years. Glycogenated stocks accumulate in a similar way in both age-classes and their more precocious and more intense use by young molluscs is not necessarily linked with their gametogenesis and growth,...

Donnees cytologiques, electrophysiologiques et biochimiques relatives au phenomene de fecondation chez le homard (Homarus gammarus ). Implication du processus d'activation sur le mecanisme d'attache des oeufs pondus ArchiMer
Goudeau, M; Lachaise, F; Kubisz, P; Goudeau, H.
Electrophysiological measurements and related cytological controls were done on immature and submature oocytes of Homarus gammarus . By chromatography (HPLC) and radio-immunoassays (RIA) it was established that submature oocytes displayed different ecdysteroids. Furthermore, the structure of the stalk (funiculus) for the laid eggs attachment was analyzed. it consisted of the two superimposed vitelline envelopes which were likely modified by the cortical reaction exudate during the fertilization process. In addition, the successive secretory phases, regarding to the embryonic envelopes were evidenced. Finally, the ecdysteroid titers of embryonic stages were measured.

Effects of Garlic (Alliumsativum) and chloramphenicol on growth performance, physiological parameters and survival of Nile tilapia (Oreochromis niloticus) J. Venom. Anim. Toxins incl. Trop. Dis.
Shalaby,A. M.; Khattab,Y. A.; Abdel Rahman,A. M..
We studied and compared the effects of chloramphenicol antibiotic and garlic (Allium sativum), used as immunostimulants and growth promoters, on some physiological parameters, growth performance, survival rate, and bacteriological characteristics of Nile tilapia (Oreochromis niloticus). Fish (7±1g/fish) were assigned to eight treatments, with three replicates each. Treatment groups had a different level of Allium sativum (10, 20, 30, and 40g/kg diet) and chloramphenicol (15, 30, and 45mg/kg diet) added to their diets; the control group diet was free from garlic and antibiotic. Diets also contained 32% crude protein (CP) and were administered at a rate of 3% live body weight twice daily for 90 days. Results showed that the final weight and specific growth...

Effects of microalgal diet on growth, survival, biochemical and fatty acid composition of Ruditapes decussatus larvae ArchiMer
Andres Aranda-burgos, Jose; Da Costa Gonzalez, Fiz; Novoa, Susana; Ojea, Justa; Martinez-patino, Dorotea.
Successful bivalve larval growth and survival depend on stored reserves provided by diet. The aim of this study was to evaluate the effects of microalgal diet on growth, survival, together with biochemical and fatty acid composition during larval development in grooved carpet shell (Ruditapes decussatus). Four mono- and multi-species diets were tested: (1) Isochrysis galbana, Pavlova lutheri and Chaetoceros muelleri (1:1:1, IPC); (2) I. galbana, P. lutheri and C. muelleri (1:1:2, IP2C); (3) I. galbana and P. lutheri (1:1, IP); (4) C. muelleri (C). Our results showed that feeding regime greatly influenced larval growth and survival, as well as biochemical and fatty acid composition. Higher growth and survival rates were observed in the IPC, IP2C and C...

Estimation of Parameters Responsible for the Generation of Off-Flavor in Some Indian Varieties of Soybeans Eprints@IARI
Dahuja, Anil; Madaan, T R.
Production of hydroperoxides and volatile aldehydes, having low olfactory thresholds by lipoxygenase (LOX) action, is an important problem in the effective use of soybeans as food ingredients. In this study, researchers examined sixteen soybean varieties forLOXactivity, thiobarbituric acid (TBA) number, a measure of lipid peroxides, and carbonyl value, an index of ketone compounds, responsible for off-flavor. Among the soybeans tested, PK416 and JS7015 had the lowest levels of LOX activity, TBA number as well as carbonyl value. The highest value for these parameters were observed in Pb-1 and Bragg. These results suggest that PK416 and JS7015 could be excellent soybean sources for making good quality soy products.

Evolution des acides nucleiques au cours du developpement larvaire de la crevette rose Palaemon serratus (Pennant). ArchiMer
Campillo, Albert; Regnault, M.; Luquet, P..
The evolution of nucleic acids in larvae of P. serratus reared in the laboratory from hatching to metamorphosis has been studied. From the 1st larval stage to the post-larval stage, DNA and RNA concn decrease: from 185 to 95 uMoles-bases/g PSD for DNA and from 133.5 to 78.75 uMoles-bases for RNA. The concn decrease is not regular; it is emphasized between stages 4 and 5 on the one hand, and between stage 7 and the post-larva on the other hand. The amount of DNA and RNA per larva increases proportionally to the wet weight from stage 1 to the post-larva. As the weight is multiplied by 7.6, total DNA and total RNA are multiplied by 3.80 and 4.25 respectively. The RNA/DNA ratio has a mean value of 0.77; it increases slightly from stage 1 (0.72) to the...

Hematological and biochemical features of postpartum fever in the heavy draft mare OAK
AOKI, Takahiro; KIMURA, Yuki; OYA, Anna; CHIBA, Akiko; ISHII, Mitsuo; NAMBO, Yasuo.
Heavy draft mares potentially have a higher risk of suffering from postpartum fever (PF) than light breed mares. The purpose of this study was to compare hematological and biochemical features between clinically healthy mares (n=40) and PF-affected mares (n=16). Mares were classified as having PF when their rectal temperature rose to >38.5°C within 96 hr of foaling. The numbers of leukocytes, lymphocytes, and neutrophils and the serum magnesium level were significantly lower in PF-affected mares. The serum SAA and NEFA levels were significantly higher in PF-affected mares. Strong inflammation responses, fat mobilization associated with negative energy balance and possibly endotoxin participate in hematological and biochemical features of PF in heavy...
