background: use of glucosamine as an alternative treatment for osteoarthritis is becoming more frequent, including in those who have diabetes at the same time. the results from in vitro and animal studies propose that glucosamine may inversely affect glucose metabolism. however, the recommended dose of oral glucosamine in healthy people or diabetics did not have such effects consistently. the a...

background: the homeostasis model assessment of insulin resistance (homa-ir) is a useful model for application at large epidemiologic studies. the aim of this study was to determine the homa cut off values to identify insulin resistance (ir) and metabolic syndrome (ms) in qazvin, central iran. methods: overall, 480 men and 502 women aged 20-72 yr attended in this cross sectional study from sept...

Objective: Adiponectin (an insulin sensitizing protein) and zinc have insulin like effect. This study was conducted to assess the effect of zinc supplementation on serum adiponectin and insulin resistance in first degree relatives of diabetic patients. Materials and Methods: This study was a randomized clinical trial performed on 58 first degree relatives of diabetic patients with normal gluco...

OBJECTIVE This study aims to investigate whether pre-operative Homeostasis Model Assessment Insulin Resistance (HOMA-IR) value is a predictor in non-diabetic coronary artery bypass grafting patients in combination with hemoglobin A1c, fasting blood glucose and insulin levels. METHODS Eighty one patients who were admitted to Cardiovascular Surgery Clinic at our hospital between August 2012 and...

Background: Obesity is a very common disorder resulting from an imbalance between food intake and energy expenditure, and it has a substantial impact on the development of chronic diseases.  The aim of this study was to examine the association of INSIG2 (rs7566605) gene polymorphism with obesity and obesity associated phenotypes in North Indian subjects. Methods: The variants were investig...

OBJECTIVE Fetuin-A is a protein secreted from the liver that inhibits arterial calcification deposition and can contribute to insulin resistance. Hyperthyroidism is also associated with insulin resistance. It is not known whether hyperthyroidism has an effect on fetuin-A levels. METHODS We measured fetuin-A levels and homeostasis model of assessment-insulin resistance before hyperthyroidism t...

Abstract Objective: Insulin resistance and hyperinsulinemia are common among the women with polycystic ovarian syndrome (PCOS). Familial aggregation of PCOS has implications on the role of heredity in this disease. The aim of this study was to evaluate insulin resistance among the fathers, mothers, and siblings of the women with PCOS referring to the clinics affiliated to Shiraz University of ...

conclusions therapeutic dose of vitamin d can improve vitamin d status and glycemic indicators. but it seems that an 8-week intervention period was not sufficient to reveal the possible effects of vitamin d on serum adiponectin levels. results after 8-week intervention, serum 25-hydroxyvitamin d significantly increased and reached the normal levels in patients receiving vitamin d (p < 0.001) an...
