Active clinical trials for "Insulin Resistance"

Probiotics are defined as live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Smectite is a natural silicate clay belonging to the dioctahedral smectite class formed from aluminomagnesium silicate. It is not absorbed from the gastrointestinal tract, but binds to intestinal mucous, forms multilayer structure with high plastic viscosity and powerful coating properties hence preserving integrity of the mucus, and has the ability to absorb directly bacterial toxins, bacteria, viruses and bile salts. The current study aim was to conduct placebo-controlled randomize clinical trial for the efficiency of a combination of multiprobiotics with smectite (Symbiter-Forte formulation) as an adjunction to the standard anti-diabetic therapy on IR, glycemic control parameters, β-cells functional activity, anthropometric parameters and markers of a chronic systemic inflammatory response in type 2 diabetes patients.

The aim of this project is to determine role for ET-1 in individuals with obesity.

The purpose of this study is to measure the metabolic and behavioral effects of a 12-week yoga program coupled to health education (HED) compared to HED alone.

The objectives of this study are to evaluate the safety and tolerance of 20 mg (10 mg BID) of HE3286 when administered orally over 28 days to obese insulin-resistant adult subjects and, to assess the activity of HE3286 on insulin sensitivity and hepatic glucose production in obese insulin-resistant adult subjects.

The study is designed to test the following primary hypothesis: Aerobic exercise training will improve insulin sensitivity in insulin resistant subjects through changes in the major cellular signaling pathways and and/or their regulators. Accordingly, the proposed study is designed to accomplish the following specific aims: Quantitate how exercise training improves insulin sensitivity and decreases cardiovascular risk factors in a general population of lean, nondiabetic, insulin resistant subjects. Effects on known cardiovascular risk factors including blood pressure and serum lipoproteins will be evaluated. Change in regional adiposity will also be measured Determine the effects of a program of regular aerobic exercise on in the insulin receptor signaling pathway. Biopsies of vastus lateralis muscle from insulin resistant subjects will be obtained before and after a hyperinsulinemic glucose clamp. This procedure will take place in the untrained state and after exercise training. The investigators will measure changes in the insulin receptor and the activity of the major components of the intracellular insulin signaling pathway. The investigators will also look intracellular proteins that regulate this signaling pathway.

Dietary strategies for alleviating the metabolic complications such as diabetes associated with obesity are actively being pursued as alternatives to pharmaceutical interventions The genus Vaccinium (e.g. blueberry, blaeberry, cranberry) has been used traditionally as a source of folk remedies for established diabetic symptoms, primarily as leaf or stem infusions or decoctions. Berries from this family such as blaeberry (BL) and blueberry (BB) are enriched in anthocyanins, polyphenolics recognized for their ability to provide and activate cellular antioxidant protection, inhibit inflammatory gene expression, and consequently protect against oxidant-induced and inflammatory cell damage and cytotoxicity. The association of obesity with adipose tissue stress, macrophage recruitment, and inflammatory gene expression suggests that eating edible berries from this genus might provide an effective alternative or supplementary intervention to attenuate obesity- associated inflammation and the associated insulin resistance. The aim of this study is to determine the effects of anthocyanin supplementation in the form of a concentrated blaeberry extract on insulin resistance and inflammation particularly in the adipose tissue following a three week supplementation period.

Stress hyperglycemia during myocardial infarction (MI) is related to mortality at short and long term. Recent studies, however, revealed that chronic statin treatment may decrease both insulin sensitivity and secretion immediately after statin therapy initiation. This study aim was to investigate the dose-dependent effect of statins on insulin sensitivity in patients in the acute phase of MI.

The purpose of this research study is to test an automated blood glucose control system that includes a new component designed to adapt to stress. The importance of this component is that when Type 1 Diabetics are stressed (for example, from illness or infection), their body is resistant to the effects of insulin. The investigators will be adjusting their blood glucose using insulin and glucagon and making their body less sensitive to insulin with a steroid, hydrocortisone. Insulin is a hormone that lowers blood glucose. Glucagon raises blood glucose when it is low. Both are natural hormones made by people without diabetes. Hydrocortisone is a steroid that will increase their blood glucose temporarily and will be given every 4 hours. All subjects will participate in two 33 hour experiments. One experiment will use the adaptive version of the sensor-based glucose control system. The other study will use the original version of the control system, without the adaptive component, for the first 13 hours. Then, the adaptive component will be added to the glucose control system for the remaining 20 hours of the study. Our primary goal is to assess the effectiveness of the adaptive component to control glucose levels in the presence of steroid-induced insulin resistance in persons with Type 1 Diabetes Mellitus.

Hypothesis: Chronic intake of pistachios improves glucose metabolism and insulin resistance status thus contributing to decrease the risk of type 2 diabetes mellitus and its associated abnormalities.

The purpose of this research is to study the effects of Vitamin D supplementation on the body's response to insulin (a hormone that controls blood sugar), on inflammation, and on specific cells and processes in fat tissue.
