Transporters involved in glucose and water absorption in the Dysdercus peruvianus (Hemiptera: Pyrrhocoridae) anterior midgut
(ELSEVIER SCIENCE INC, 2010)
Little is known about insect intestinal sugar absorption, in spite of the recent findings, and even less has been published regarding water absorption. The aim of this study was to shed light on putative transporters of ...
Transporte jejunal eletrogênico da glicose em ratos com deficiência de niacina.
The active electrogenic absorption of glucose was studied in 12 niacin deficient rats using a method for measuring changes in transmural potential difference across jejunal mucosa. The glucose was infused in 6 different ...
Paracellular absorption in laboratory mice: Molecule size-dependent but low capacity
Water-soluble nutrients are absorbed by the small intestine via transcellular and paracellular processes. The capacity for paracellular absorption seems lower in nonfliers than in fliers, although that conclusion rests ...
Cinética do transporte jejunal de glicose em ratos com deficiência de niacina.
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 ...
Intestinal perfusion indicates high reliance on paracellular nutrient absorption in an insectivorous bat Tadarida brasiliensis
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)
