The effects of altered gastric emptying on glucose absorption and kinetics are not well understood in nondiabetic obese adults. The aim of this work was to develop a physiology-based model that can characterize and compare interactions among gastric emptying, glucose absorption, and glycemic control in nondiabetic obese and lean healthy adults. Dynamic glucose, insulin, and gastric emptying (me...
background: one of the major sources of drinking water contamination is nitrate. nitrate concentrations of more than the standard levels (45mgl -1 based on nitrate) could cause methemoglobinemia in children. the aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (gfh). also in this study, the effect of factors such as initial concentration of nitrate, contac...
The hypocholesterolemic activities of pamaqueside and tiqueside, two structurally similar saponins, were evaluated in cholesterol-fed rabbits. The pharmacological profiles of the saponins were virtually identical: both dose-dependently decreased the intestinal absorption of labeled cholesterol 25-75%, increased fecal neutral sterol excretion up to 2.5-fold, and decreased hepatic cholesterol con...
Studies on the kinetics of gas-phase chemical reactions currently rely calculations or simulations and lack simple, fast, accurate direct measurement methods. We developed a tunable laser molecular absorption spectroscopy system to achieve measurements such by using wavelength modulated performed online diagnostics concentration, reaction temperature, pressure change during redox ozone with nit...
We have investigated the mechanism responsible for the diffusive component of intestinal glucose absorption, the major route by which glucose is absorbed. In perfused rat jejunum in vivo, absorption was strongly inhibited by phloretin, an inhibitor of GLUT2. The GLUT2 level at the brush-border membrane increased some 2-fold when the luminal glucose concentration was changed from 0 to 100 mM. Th...
