Plasma glucose, insulin, and C-peptide concentrations were determined in response to graded infusions of glucose, and insulin secretion rates were calculated over each sampling period. Measurements were also made of insulin clearance, resistance to insulin-mediated glucose, uptake, and the plasma glucose, insulin, and C-peptide concentrations at hourly intervals from 8:00 AM to 4:00 PM in respo...

In this study, the effects of late gestational undernutrition (LGU) on plasma concentration of insulin-like growth factor 1 (IGF-I), leptin, insulin and glucose in subsequent sucking lambs was investigated. Ten twin-bearing ewes were fed either restrictedly (Restricted) or adequately (Control) during the last six weeks of gestation and were fed ad libitum after parturition. Blood samples were t...

1. Danazol elevates plasma insulin, plasma glucagon and serum low-density lipoprotein concentrations and reduces the serum high-density lipoprotein concentration. 2. Associations between these disturbances were studied in 17 women receiving danazol therapy for endometriosis. Eleven women underwent intravenous glucose tolerance tests with measurement of plasma glucose, insulin, C-peptide and glu...

Plasma glucose concentrations are tightly regulated and maintained within a narrow range in non-diabetic individuals. Maintenance of this physiological state is primarily a function of the ability of the pancreatic β-cells to modify insulin secretion rate (ISR), thus preventing wide-swings in plasma glucose concentrations. As a consequence, and in contrast to plasma glucose concentrations, plas...

Ketosis is an important metabolic disease of high milk-producing cows. There are significant changes in many metabolite and hormonal concentrations in metabolic diseases. This study was carried out to assess the concentrations calcium (Ca), selenium (Se), total antioxidant (TAOC), insulin, free triiodothyronine (fT3) and free thyroxine (fT4) in cows with subclinical and clinical ketosis. This s...

OBJECTIVE Overfeeding is associated with insulin resistance. Studies on animals suggest this is likely due to disruption of fatty acid metabolism and increased plasma free fatty acid (FFA) availability during the night. We tested the hypothesis that overfeeding induces insulin resistance and increases nocturnal but not daytime plasma FFA availability in human subjects. DESIGN AND METHODS We m...

background and aim: the aim of this study was to determine the effect of legume intake in therapeutic lifestyle change (tlc) on fasting insulin, fasting blood glucose, hba1c and homeostasis model assessment insulin resistance (homa-ir) in patients with type 2 diabetes. materials and methods: in this randomized crossover trial, 31 subjects with type 2 diabetes in the age range of 50 to 80 years ...

objectives insulin resistance has been considered as the most important component of type 2 diabetes mellitus (dm2). plants used in folk medicine to treat diabetes mellitus represent a viable alternative for the control of this disease. this study was aimed to examine the antidiabetic effects of three iranian medicinal plants i.e. urtica dioica, trigonella foenum-graecum and fumaria officinalis...
