| 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... |

| 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... |

| 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... |

| 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,... |

| ABSTRACT The aim of this study was to investigate the effects of dietary fumaric acid (FA) on the growth performance, hematological parameters and serum biochemistry in broilers under heat stress (HS) condition. A total number of 200 broilers were allocated to five treatments including the thermoneutral group, which was reared at standard ambient temperature and fed basal diet (CONT) and four heat-stressed groups, which were held at 32 ± 1ºC aged from 22 to 42 days and fed the basal diet supplemented with 0, 5, 10 and 15 g/kg FA, respectively. On day 42, body weight and feed intake were measured and feed conversion ratio was calculated. Blood was collected for the estimation of hematological and biochemical parameters. HS impaired the growth performance,... |

| 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... |

| 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... |

| Durante la Tercera Expedición Ecuatoriana a la Antártida en enero-febrero de 1991, como parte de los estudios de evaluación del impacto ambiental, se ha iniciado un reconocimieno físico, químico y biológico de un cuerpo de agua dulce en Punta Fort Williams, Isla Greenwich, Shetland del Sur. Se escogió un lago formado en una depresión del terreno con aporte de tipo glacial, expuesto al viento por tres de sus lados, poca profundidad por lo que es bién oxigenado y existe disponibilidad de nutrientes por degradación de materia orgánica vegetal proveniente de los alrededores y acarreada por los vientos. El lago es oligotrófico, sin aporte significativo de excretas de aves y mamíferos. Del plancton estudiado se define que hay un importante componente... |

| 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... |
