Nitric oxide activates guanylate cyclase to form cGMP, comprising a signalling system that is believed to be a distinct mechanism for increasing glucose transport and metabolism in skeletal muscle. The effects of a selective cGMP phosphodiesterase inhibitor, zaprinast, on basal glucose utilization was investigated in incubated rat soleus muscle preparations isolated from both insulin-sensitive ...

Background: To compare the chromium picolinate with metformin in Clomiphene citrate resistant PCOS patients. Materials and Methods: This was a randomized clinical trial being performed at university affiliated clinics including 92 women with Clomiphene citrate-resistant PCOS who were randomly assigned to receive chromium picolinate (200 μg daily) or metformin (1500 mg daily) for 3 months. Anthr...

Insulin resistance is caused by the inability of target tissues to respond to insulin. Bay leaf (Eugenia polyantha Wight) extract has been used for the treatment of insulin-resistant type-2 diabetes mellitus (IRDM), but it has low solubility and bioavailability. To overcome these problems, chloroform extract of bay leaves was formulated into a self-microemulsifying drug delivery system (SMEDDS)...

Whilst the human body expends energy constantly, the human diet consists of a mix of carbohydrates and fats delivered in a discontinuous manner. To deal with this sporadic supply of energy, there are transport, storage and utilisation mechanisms, for both carbohydrates and fats, around all tissues of the body. Insulin-resistant states such as type 2 diabetes and obesity are characterised by red...

Alterations in the production of or the sensitivity to leptin, the protein encoded by the ob gene, cause obesity and diabetes in rodents. We evaluated the isolated relationship between leptin and insulin sensitivity in lean and obese humans. Three groups of subjects who were carefully matched for either insulin sensitivity (determined by the modified intravenous glucose tolerance test and minim...

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.   ...

Increasing evidence points to insulin resistance as a primary etiologic factor in the development of nonischemic heart failure (HF). The myocardium normally responds to injury by altering substrate metabolism to increase energy efficiency. Insulin resistance prevents this adaptive response and can lead to further injury by contributing to lipotoxicity, sympathetic up-regulation, inflammation, o...
