To evaluate the roles of hyperglycemia and increased plasma FFA level in the development of insulin resistance, we examined the effects of phlorizin and acipimox treatments on tissue sensitivity to insulin in streptozotocin(STZ)-diabetic rats. Insulin sensitivity was assessed with the glucose-insulin clamp technique. Blood glucose concentration was clamped at basal levels of control and diabeti...

of baseline measurements, a 7-day control diet, pre HFD measurements, a 5-day HFD period, and post HFD measurements. Studies 1 and 2 differed in that study 1 included an IVGTT on day 8 and 14, whereas study 2 included a high fat meal challenge on day 8 and 14. Intravenous glucose tolerance test (IVGTT). All volunteers were fasted and placed in the supine position prior to the IVGTT, before high...

The kinetics of nonesterified fatty acid (NEFA) metabolism in humans requires quantification to facilitate understanding of diseases like type 1 and 2 diabetes, metabolic syndrome, and obesity, and the mechanisms underpinning various interventions. Oral glucose tolerance tests (OGTT) and glucose meal tolerance tests (MTT) are potentially useful procedures for enabling quantification of NEFA kin...

The study goals were to (1) establish the variability in postprandial glucose control in healthy young people consuming a mixed meal and, then (2) determine the acute and residual impact of a single exercise bout on postprandial glucose control. In study 1, 18 people completed two similar mixed meal trials and an intravenous glucose tolerance test (IVGTT). There were strong test-retest correlat...

Several studies have shown that stress has major effects on metabolism. There is also some evidence indicating that stress may induce diabetes mellitus. The present study has investigated the role of chronic psychological stress on carbohydrate metabolism in male Wistar rats (250 ± 50 g). Animals were divided into control and test groups (n = 8/group). Blood samples were obtained by tail snippi...
