13. The Effects of Different Amount of Protein and Vitamin e Supplementation in Rations on Lipid and Antioxidant Metabolism of Broilers Exposed to Heat Stress
ABSTRACT Heat stress, causes economic losses and has negative effects on both broiler husbandry and animal welfare. Nutritional strategies are applied for minimizing the negative effects of heat stress. In the present study, at the finishing period (24-39 days of age) of heat stress, the effects of diet involving 21% and 19% proteins and vitamin E on lipid m

14. Methionine + cystine levels and vitamin B6 supplementation on performance and enzyme expression of methionine metabolism of gilts from 75 to 100 kg
ABSTRACT This study was carried out to evaluate the effect of different levels of standardized ileal digestible (SID) methionine + cystine (Met+Cys) and vitamin B6 supplementation on the performance, blood variables, and gene expression of enzymes involved in methionine metabolism in female pigs between 75 and 100 kg. Fifty six female pigs were used (Talent

15. Non-clinical studies in the process of new drug development - Part II: Good laboratory practice, metabolism, pharmacokinetics, safety and dose translation to clinical studies
The process of drug development involves non-clinical and clinical studies. Non-clinical studies are conducted using different protocols including animal studies, which mostly follow the Good Laboratory Practice (GLP) regulations. During the early pre-clinical development process, also known as Go/No-Go decision, a drug candidate needs to pass through severa

16. Determination of the regulatory properties of Yucca schidigera extracts on the biochemical parameters and plasma hormone levels associated with obesity
ABSTRACT Yucca schidigera Ortgies, Asparagaceae, is a herbaceous plant. Due to the high saponin content the powdered branches and leaves are used as natural food additive for human and animal. The aim of this study was to investigate the effects of Y. schidigera extracts on plasma leptin, ghrelin, adiponectin, insulin, thyroid hormones and some biochemical p

17. Models of protein and amino acid requirements for cattle
Protein supply and requirements by ruminants have been studied for more than a century. These studies led to the accumulation of lots of scientific information about digestion and metabolism of protein by ruminants as well as the characterization of the dietary protein in order to maximize animal performance. During the 1980s and 1990s, when computers became

18. Different true-protein sources do not modify the metabolism of crossbred Bos taurus × Bos indicus growing heifers
The present study was conducted to investigate the effect of alternative true-protein sources to soybean meal, with different ruminal degradability, using a sugarcane-based diet, on nutrient digestion, ruminal fermentation, efficiency of microbial protein synthesis and passage rate in prepubertal dairy heifers. Eight crossbred rumen- and duodenum-cannulated

19. What makes the heart of Boa constrictor (Squamata: Boidae) beat faster?
Body size is highly correlated with metabolism, which in turn influences physiological rates such as heart rate. In general, heart rate is negatively influenced by the size of animal's body, but there is insufficient data corroborating this pattern in snakes. This study evaluated how body size affects heart rate in captive Boa constrictor Linnaeus, 1758. We

20. Antioxidant effect of mogrosides against oxidative stress induced by palmitic acid in mouse insulinoma NIT-1 cells
Excessive oxidative stress in pancreatic β cells, caused by glucose and fatty acids, is associated with the pathogenesis of type 2 diabetes. Mogrosides have shown antioxidant and antidiabetic activities in animal models of diabetes, but the underlying mechanisms remain unclear. This study evaluated the antioxidant effect of mogrosides on insulinoma cells un

21. Classes of secondary metabolites identified in three legume species
The objective of this study was to identify secondary metabolite classes of tropical kudzu, perennial soybean and archer legumes through identification by phytochemical screening and confirmation by infrared (IR), ¹H and carbon-13 NMR spectroscopy of fractions obtained by organic solvents partition of crude extracts. These analyses allowed for proposing the

22. Efeitos da suplementação com melatonina e do treinamento físico aeróbio sobre o perfil metabólico de ratos diabéticos induzidos por estreptozotocina. / Effects of melatonin supplementation and physical training on metabolic profile in diabetic rats induced by streptozotocin.
A prevalência do diabetes mellitus tem aumentado exponencialmente, o estilo de vida noturna e o avanço na idade estão envolvidos neste mecanismo, influenciando também a produção de melatonina. O animal pinealectomizado apresenta resistência insulínica e redução na síntese de GLUT4. Mostramos que no músculo sóleo, houve um aumento na taxa de oxid

23. Efeito de duas variedades de feijão (Phaseolus vulgaris) no metabolismo lipídico de hamsters / Effect of two beans varieties (Phaseolus vulgaris) in hamster lipid metabolism [Dissertation].
Carioca and black beans are the varieties of Phaseolus vulgaris most consumed on Brazil Southwest. It is well described that some legumes, as soy and cowpea beans, have hypocholesterolaemic effects. To test cholesterol-lowering properties of carioca and black beans, two biological assays were conducted. Golden Syrian hamsters, 21 days old, were housed indivi
