Influence of short-term submaximal exercise on parameters of glucose assimilation analyzed with the minimal model.

After exercise, glucose uptake in tissues increases by insulin-dependent and -independent mechanisms. We evaluated whether these two effects of exercise on glucose disposal can be detected with the minimal model technique. Seven healthy volunteers were submitted at random order to two frequently sampled intravenous glucose tolerance test (FSIVGTTs), one at rest and the other 25 minutes after a 15-minute exercise test.

Protective effect of gamma-hydroxybutyrate and nicotinamide on low-dose streptozotocin-induced diabetes in mice.

The purpose of this study was to investigate the effect of a treatment by gamma-hydroxybutyrate (GHB) and nicotinamide (NA) on low-dose streptozotocin (STZ)-induced diabetes in mice. Mean plasma glucose level was significantly elevated in mice given STZ by day 12 after the first STZ injection compared to controls (15.0 +/- 4.

Effects of oral zinc gluconate on glucose effectiveness and insulin sensitivity in humans.

Zinc improves both insulin secretion and insulin sensitivity, and exerts insulin-like effects. We investigated its acute effects on the parameters of glucose assimilation determined with the minimal model technique from frequent sampling intravenous glucose tolerance test (FSIVGTT) in seven healthy volunteers. FSIVGTTs (0.
