The purpose of the present study was to investigate the effect of endurance (ET), resistance (RT) and concurrent training (CT) on plasma levels of visfatin, insulin, glucose and insulin resistance of non-athlete men with Obesity. It was a semi-experimental study. Thirty six men [age: 21.48 (0.25), and BF%: 27.39 (0.52)], voluntarily participated in this study after public announcement in univer...

1. Whole-body, hind-limb and uterine tissue metabolism of glucose was studied using a combination of isotopic and arterio-venous difference techniques in shorn and unshorn pregnant sheep over the final 4 weeks of pregnancy. This was combined with the measurement of the concentrations of oxygen and carbon dioxide in arterial blood and plasma concentrations of lactate, acetate, non-esterified fat...

CONTEXT Women with previous gestational diabetes mellitus (pGDM) are at high risk of developing type 2 diabetes mellitus in the future. The role of adipokines in women with pGDM has not been established. OBJECTIVE We investigated whether circulating adipokine concentration is associated with abnormal glucose homeostasis in women with pGDM. DESIGN, SETTING, PATIENTS, AND MAIN OUTCOME MEASURES:...

BACKGROUND Accumulating data suggest a novel role for bile acids (BAs) in modulating metabolic homeostasis. BA treatment has been shown to improve glucose tolerance and to increase energy expenditure in mice. Here, we investigated the relationship between fasting plasma BAs concentrations and metabolic parameters in humans. FINDINGS Fasting plasma glucose, insulin and lipid profile were measu...

Adenosine A(1) and A(2A) receptor subtypes modulate metabolism in adult mammals. This study was designed to determine the role of these receptors in regulating plasma levels of insulin, glucose, and lactate in 20 chronically catheterized fetal sheep (>0.8 term). In normoxic fetuses (Pa(O(2)) approximately 24 Torr), systemic blockade of A(1) receptors with DPCPX (n = 6) increased plasma concentr...

The effects of infusion of clonidine, an a2-adrenergic agonist, on plasma insulin-like growth factor-I (IGF-I) concentrations were investigated with a single growth hormone (GH) injection in pigs. Four barrows were subjected to four treatments: saline infusion with a vehicle injection, clonidine infusion (0.5 nmol/kg/min for 8 h) with a vehicle injection, saline infusion with a bovine GH (bGH:1...

OBJECTIVE We tested the hypotheses that in nondiabetic individuals, partial inhibition of insulin secretion with the ATP-sensitive K(+) channel agonist (opener) diazoxide, compared with placebo, results in higher plasma glucose and higher plasma glucagon concentrations after a mixed meal and after administration of the sulfonylurea glimepiride. RESEARCH DESIGN AND METHODS Plasma glucose, insu...

objective(s):in insulin resistance, the insulin action in liver, muscles and adipocytes decreases and result in hyperglycemia, dyslipidemia and hyperinsulinemia. in this study we evaluate the effect of zataria multiflora extract on insulin sensitivity in high fructose fed insulin resistant rats, since this extract was shown antihyperglycemic effect in streptozotocin induced diabetes in rats.   ...
