13. Bioatividade do grão de amaranto : avaliação in vitro da atividade ligante de acidos biliares e inibidora da enzima conversora de angiotensina. / Bioactivity of the amaranth grain : in vitro assessment of the binding bile acids and inihibitory activity of the angiotensin converting enzyme.
Amaranth has been highlighted as an excellent alternative or complementary source of food protein due to its balanced amino acid composition. The culture of amaranth has been introduced into Brazil on account of its optimum nutritional (high protein content and better biological quality than that of cereal protein) and functional quality, apart from its agri

14. Study of the nutritionals effects of the pulp flour and muciagens extracted from okra (Hibiscus esculentus L.). / Estudo dos efeitos nutricionais da farinha de polpa e mucilagem extraida do quiabo (Hibiscus esculentus L.).
Dietary fiber is understood as any polymer normally occurring in foods, generally of carbohydrate nature, that is not digested and absorbed in the upper digestive tract and that is responsible for various physiological and biochemical effects in the lower gastrointestinal tract and the rest of the body, including alteration of the distribution of the bowel m

15. Parameters of security and functionality of the Bifidobacterium isolated from newborn, with potential of use as probiotics in human milk banks / Parâmetros de segurança e funcionalidade de bactérias bífidas isoladas de recém-nascidos, com indicação de uso como probiótico em bancos de leite humano
The objective of this study was to evaluate some parameters of security and functionality currently recommended for validation of probiotics. The parameters evaluated were antimicrobial susceptibility, antagonism to the growth of pathogens, oral chronic toxicity and bacterial translocation of new lineages of Bifidobacterium breve isolated from newborn, with

16. Antiulcerogenic effect of Chlorella vulgaris extract / Efeito anti-ulcerogenico do extrato de Chlorella vulgaris
About 10%of the world?s population suffer from peptic ulcer, within this percentage we find thousands of Brazilians. This pathology is caused by an unbalance between the protection and attack mechanisms of the stomach lining, and is the result of the association of various endogenous attack factors (pepsin, acid, bile), exogenous factors pertaining to life s

17. Influences of alpha-tocopherol on cholesterol metabolism and fatty streak development in apolipoprotein E-deficient mice fed an atherogenic diet
Although the role of oxidized lipoproteins is well known in atherogenesis, the role of vitamin E supplementation is still controversial. There is also little information about cholesterol metabolism (hepatic concentration and fecal excretion) in the new models of atherosclerosis. In the present study, we evaluated the effect of moderate vitamin E supplementa

18. Formation of delta 2- and delta 3-cholenoic acids from bile acid 3-sulfates by a human intestinal Fusobacterium strain.
We isolated two strains of an unnamed Fusobacterium species from human intestinal microflora, which stereospecifically transformed bile acid 3-sulfates into C-3-unsubstituted, ring A-unsaturated bile acids. Both 3 alpha- and 3 beta-sulfates of 5 beta-bile acids were metabolized to delta 3-5 beta-cholenoic acids; 3 beta-sulfates of 5 alpha-bile acids were con

19. Bile acid excretion: the alternate pathway in the hamster.
The quantitative significance of renal excretion of bile acid ester sulfates as an alternate excretory pathway was evaluated in hamsters. After bile duct ligation, total serum bile acid fell from a mean level of 454 microgram/ml at 24 h to 64 microgram/ml by 96 h. During this period the bulk of the bile acid pool could be accounted for as esterified bile aci

20. Effect of Glycine-Conjugated Bile Acids with and without Lecithin on Water and Glucose Absorption in Perfused Human Jejunum
Perfusion studies were performed in healthy volunteers to test whether the secretory effect of conjugated bile acids, previously shown for the colon, was also present in the jejunum. A perfusion system with a proximal occlusive balloon (and continuous aspiration of duodenal secretions) was used; isotonic test solutions contained glycine-conjugated bile acids

21. Bile acids: regulation of synthesis
Bile acids are physiological detergents that generate bile flow and facilitate intestinal absorption and transport of lipids, nutrients, and vitamins. Bile acids also are signaling molecules and inflammatory agents that rapidly activate nuclear receptors and cell signaling pathways that regulate lipid, glucose, and energy metabolism. The enterohepatic circul

22. Role of primary and secondary bile acids as feedback inhibitors of bile acid synthesis in the rat in vivo.
The effect of various primary and secondary bile acids on the rates of synthesis of all major bile acids was studied in the live rat with an extracorporal bile duct. Bile acid synthesis was determined using HPLC based on mass or by isotope dilution. Derepressed rates of bile acid synthesis (30-54 h) were inhibited by an infusion of taurocholic acid only at a

23. Effects of acute changes of bile acid pool composition on biliary lipid secretion.
To elucidate the mechanism responsible for the bile acid-induced changes of biliary lipid secretion, we evaluated bile flow and biliary output of bile acids, cholesterol, phospholipids, and alkaline phosphatase activity in seven cholecystectomized subjects with a balloon occludable T-tube during two experimental periods: (a) depletion of the endogenous bile

24. Production of thermostable direct hemolysin by Vibrio parahaemolyticus enhanced by conjugated bile acids.
The effects of conjugated bile acids, glycocholic acid, and taurocholic acid (TC) on production of thermostable direct hemolysin (TDH) by Vibrio parahaemolyticus were determined by a reversed passive latex agglutination assay against TDH. The amount of TDH excreted in growth medium containing either glycocholic acid or taurocholic acid (5 mM/liter) was, on a
