Dopaminergic signaling is one of the regulatory pathways being investigated for its implication in glucose metabolism. The aim of this study was to determine the effect of cabergoline on biochemical and anthropometric parameters in prediabetes stage (impaired fasting glucose and impaired glucose tolerance). In this double blind, placebo-controlled, pilot study, 27 prediabetic adults were random...

BACKGROUND The definition and treatment of glucose intolerance during pregnancy are matters of intense controversy. Our goal was to examine the value of the 75-g oral glucose tolerance test (OGTT) in terms of its ability to predict birth weight percentile in a group of women with singleton pregnancies who received minimal treatment for their glucose intolerance. METHODS We reviewed the result...

The secretion of leptin is dually regulated. In fasting animals, plasma leptin concentrations reflect body fat stores, whereas the incremental leptin response to fasting or refeeding most likely reflects insulin-mediated energy flux and metabolism within adipocytes. Impaired secretion of leptin in either pathway could result in obesity. We therefore measured plasma leptin concentrations in fast...

BACKGROUND Patients with dyslipidemia have an increased risk of developing type 2 diabetes, and diabetic patients often have dyslipidemia. Potential genetic connections of fasting plasma glucose with plasma lipid profile were evaluated using hyperlipidemic mice. METHODS 225 male F2 mice were generated from BALB/cJ (BALB) and SM/J(SM) Apoe-deficient (Apoe-/-) mice and fed a Western diet for 5 ...

OBJECTIVE To evaluate the role of adiposity in the relationship between specific and surrogate estimates of insulin-mediated glucose uptake (IMGU) in a large nondiabetic population. RESEARCH DESIGN AND METHODS Healthy volunteers were classified by BMI into normal weight (<25.0 kg/m(2), n = 208), overweight (25.0-29.9 kg/m(2), n = 168), and obese (>or=30.0 kg/m(2), n = 109) groups. We then ass...

BACKGROUND Helicobacter pylori infection raises basal and meal stimulated serum gastrin concentrations and lowers iron stores, which may in turn reduce fasting plasma glucose concentrations in the population. AIM To determine whether H pylori infection leads to lower fasting plasma glucose concentrations in the population. METHODS One hundred and seventy three women and 165 men, randomly se...

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...

results thirty-four patients were hyperglycemic and 127 non diabetic. sensitivity, specificity, positive predictive value and negative predictive value of fdg-pet/ct were 90%, 88%, 87% and 91% in non diabetic and 82%, 92%, 95% and 73% in hyperglycemic patients, respectively. overall, the accuracy was higher in non diabetic than hyperglycemic patients (89% vs. 85%). conclusions accuracy of fdg-p...

AIMS/INTRODUCTION Studies suggest that salivary proteins can be used as potential non-invasive markers for clinical diagnosis and screening for diabetes. Previous reports showed that plasma alpha 2-macroglobulin (A2MG) levels were higher in diabetic patients, especially with diabetic complications. We investigated the relationship between salivary A2MG values and clinical characteristics in pat...

There is a high incidence of glucose intolerance in essential hypertension. Overactivation of the sympathetic system is one of important causes of essential hypertension. Whether sympathetic system affects glucose metabolism in patients with essential hypertension has never been reported previously. The aim of this study was to explore the association between the sympathetic system activity and...
