37. Tenacidade e investimento em seda em aranhas de teia orbicular / Tenacity and silk investment in orb web spiders
The origin of the most diverse branch of orbweavers, the Araneoidea, coincides with the origin of the viscid silk in the group Orbiculariae. Many hypotheses were proposed to explain the increased diversity in Araneoidea, however none of them explain this phenomena completely. The present work investigates a new hypothesis: the disappearance of the cribellate

38. Influência do ácido orótico no metabolismo energético cardíaco de ratos
The functional cardiac performance is closely related to energetic metabolism. Studies have shown that the disarrangements usually associated to ischemia and reperfusion, such as ionic imbalance and impairment of contratiles proteins, are consequence of installed metabolic changes, associated with a reduction of ATP levels. Several experimental and clinical

39. Adaptações coordenadas da função do pâncreas endócrino e da ação da insulina em músculo esquelético contribuem para a regulação da homeostasia glicêmica no período perinatal. / Coordenated adaptations of endocrine pancreas and skeletal muscle insulin action contribute to the regulation of glycemic homeostasis during peripartum period.
Na gravidez, o aumento da resistência à insulina é compensado por alterações morfo-funcionais na ilhota pancreática, como o aumento da proliferação e da secreção de insulina. Após o parto ocorre retorno do pâncreas às condições basais e aumento simultâneo da sensibilidade periférica à insulina. Neste trabalho estudamos os mecanismos molecul

40. Influence of stress on gene expression and broiler meat quality / Influência do estresse pré-abate na expressão gênica e qualidade da carne de frango (Gallus gallus)
Brazilian broiler production yields a considerable amount of income for the nation. Brazil is currently the world's third broiler producer and the first chicken meat exporter, contributing with 41% of the whole world market. To reach new market frontiers it is inevitable the improvement of meat quality. Among the reasons that influences final products qu

41. O papel dos lipídios na reorganização metabólica associada à dormência sazonal no lagarto teiú Tupinambis merianae (Sauria, Teidae) / The role of lipids in the metabolic reorganization associated to seasonal dormancy in tegu lizards, Tupinambis merianae (Sauria, Teiidae)
O jejum prolongado associado `a dormência sazonal é um fenômeno característico de diversos grupos de vertebrados, e os lipídios tem se mostrado bastante importantes na manutenção destes animais. No presente estudo pretendeu-se caracterizar a reorganização metabólica no jejum de 3-4 meses associado à dormência e depressão metabólica acentuada em

42. Gene Expression in Xanthomonas axonopodis pv. citri Mediated by Plant Inducible Promoter (PIP-box) / "Expressão gênica em Xanthomonas axonopodis pv. citri controlada por promotores induzidos pela planta hospedeira"
The citrus canker, caused by the bacterial pathogen Xanthomonas axonopodis pv citri (Xac), is considered worldwide as one of the most important disease of citrus crop due to the lack of resistance in citrus plants and to the absence of efficient methods to control the disease. It was already shown that several genes involved in virulence and pathogenicity in

43. Globlal gene expression analysis during germination of the aquatic fungus Blastocladiella emersonii / Análise da expressão gênica global durante a germinação do fungo aquático Blastocladiella emersonii
We conducted large scale cDNA sequencing from libraries obtained using RNA from germinating cells of the aquatic fungus Blastocladiella emersonii. Data obtained in this work, along with cDNAs from sporulating cells, lead to the discovery of nearly 4.900 different genes from B. emersonii (Ribichich et al., 2005). The putative genes were annotated and associat

44. Respostas ao estresse osmótico e hipóxico em traíra, Hoplias malabaricus (Teleostei, Erythrinedae) aspectos fisiológicos e adaptativos.
The stress level, via change in the plasma concentration of cortisol and the physiological and metabolic responses caused by osmotic shock and hypoxia and the effect of cortisol injection on theses responses, were studied in traíra, Hoplias malabaricus, injected and non-injected with cortisol exogenous (IC) and maintained in water similar to it natural envi

45. Physical training associated to tumor growth and nutritional suplementation in Walker 256 tumor-bearing rats / Atividade fisica associada ao crescimento tumoral e suplementação nutricional : estudo experimental em ratos jovens portadores do carcinossarcoma de Walker 256
The intense nutrients mobilisation of the host carcass tissue, in function of the neoplastic growth, leads to the host cachexia. Present in most of the patients with cancer, the cachexia is the state characterized by the involuntary weight loss that overtakes the protein muscle depletion increasing the degradation and/or decreasing the protein synthesis proc

46. Efeito comparativo de repositores energéticos sobre as concentrações plasmáticas de glicose e ácidos graxos livres de corredores de longa distância / Comparative effects of energetic repositors on plasma free-fatty acids and glucose of long distance runners
A reposição de glicogênio pós treino foi investigada usando uma mistura de ambos, glicose e glicose-frutose, como repositores, em atletas corredores de longa distância. Dez corredores competitivos (30±4,7 anos) foram avaliados para composição corporal e consumo alimentar antes do exercício de 90 minutos em esteira elétrica a 70% V02máx. Amostras d

47. Determination of the energetic value of corn, soybean meal and micronized full fat soybean for newly hatched chicks
There are some evidences described in the literature showing reduced energy metabolizability of ingredients for newly hatched chicks. Hence, a metabolism trial was carried out with the objective of determining the metabolizable energy of corn grain, soybean meal and micronized full fat soybean for newly hatched chicks. The method of total excreta collection

48. Reduction of the protein and phosphorus levels in diets with phytase for broilers: performance, digestibility and excretion of nutrients / ReduÃÃo dos nÃveis de proteÃna e fÃsforo em raÃÃes com fitase para frangos de corte: Desempenho,digestibilidade e excreÃÃo de nutrientes
Experiments were conducted in the Poultry Farming Sector at the Animal Science Department of the Federal University of Lavras, to evaluate the effect of the reduction of the levels of crude protein (CP) and available phosphorus(AP) in broilers diets with phytase on the performance, carcass traits, pollutant excretion, nutrient digestibility and energetic val
