Cinética do transporte jejunal de glicose em ratos com deficiência de niacina.
(1990-10-01)
The kinetic of jejunal glucose transport was studied using perfused rat jejunum in vivo. Ninety rats were fed a diet deficient in niacin and 90 a control diet. The jejunal loops of 7 groups of animal were infused each group ...
Intestinal paracellular absorption is necessary to support the sugar oxidation cascade in nectarivorous bats
(Company of Biologists, 2016-03)
We made the first measurements of the capacity for paracellular nutrient absorption in intact nectarivorous bats. Leptonycteris yerbabuenae (20 g mass) were injected with or fed inert carbohydrate probes L-rhamnose and ...
A comprehensive study of glucose transfer in the human small intestine using an in vitro intestinal digestion system (i-IDS) based on a dialysis membrane process
(Elsevier B.V., 2018)
Human digestion is a complex process that involves several phenomena: chemical and enzymatic reactions, absorption, hydrodynamic processes, and mass transfer. The most accurate way to determine the bioavailability of ...
In vivo measurement of the rate constant of liver handling of glucose and glucose uptake by insulin-dependent tissues, using a mathematical model for glucose homeostasis in diabetic rats
(Academic Press Ltd - Elsevier Science Ltd, 2018-02)
Diabetes mellitus is a disease that affects glucose homeostasis. The World Health Organization informs that there are over 347 million people in the world with diabetes. The diagnosis and characterization of glucose ...
Intestinal perfusion indicates high reliance on paracellular nutrient absorption in an insectivorous bat Tadarida brasiliensis
(Elsevier, 2013-03)
Flying vertebrates have been hypothesized to have a high capacity for paracellular absorption of nutrients. This could be due to high permeability of the intestines to nutrient-sized molecules. We performed intestinal ...
Effect of Walker 256 tumor growth on intestinal absorption of leucine, methionine and glucose in newly weaned and mature rats
(Associação Brasileira de Divulgação Científica, 1998)
High paracellular nutrient absorption in intact bats is associated with high paracellular permeability in perfused intestinal segments
(Company Of Biologists Ltd, 2014-09-01)
Water-soluble nutrients are absorbed by the small intestine via transcellular and paracellular mechanisms. Based on a few previous studies, the capacity for paracellular nutrient absorption seems greater in flying mammals ...
Influence of nutrition on the glucose absorption and tolerance test in horses submitted to different fasting periods
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 1998-12-01)
Four groups of horses of Brasileiro de Hipismo bred were submitted to fasting for 24 and 48 hours in order to study the absorption capacity of the small intestine. Two groups were fed with coast cross grass (Cynodon dactylon) ...
The capacity for paracellular absorption in the insectivorous bat Tadarira brasiliensis.
(Springer, 2013-02)
Water-soluble nutrients are absorbed by the small intestine via transcellular and paracellular processes. The capacity for paracellular absorption seems greater in fliers than in nonfliers, although that conclusion rests ...
