Filter by:The purpose of this study is to evaluate 1) the incidence of insulin resistance (a pre-diabetic state) in patients with pulmonary hypertension, and 2) test the utility of a validated PH therapy (Tracleer) versus Pioglitazone in the treatment of those patients found to have insulin resistance.
Definition: the overall objective is to examine childhood obesity with focus on NAFLD and its treatment. Further, we aimed to investigate the impact of genetic variation on obesity. The specific aims are to; - describe the degree of NAFLD among overweight and obese, Danish children. (hypothesis; the degree for pediatric NAFLD among Danish Children was equal that found in other Caucasian paediatric study populations). - investigate the effect of a multidisciplinary intervention treatment of 1 year on liver fat content. (hypothesis; the intervention could reduce the liver fat percentage and a reduction in BMI SDS would associate with a reduction in liver fat content) - Analyze changes in liver fat content in relation to changes in levels of fasting blood variables to see if any of them could be used as a clinical tool for monitoring hepatic steatosis in the clinic. (hypothesis; serum aminotransferases (separately and their ratio, respectively), serum insulin, and HOMA-IR could predict improvement in liver fat content - Investigate the association between genetic variants and obesity.
This study will critically evaluate the effects of a novel dietary fiber administered to subjects at high risk for developing diabetes to determine if this intervention will improve insulin sensitivity compared to control product administration and, thus, decrease risk for developing diabetes. The hypothesis is that consuming this novel fiber twice a day for 12 weeks will significantly decrease fasting plasma glucose, insulin and glycosylated hemoglobin values in pre-diabetic subjects (i.e. subjects with fasting plasma glucose levels 95-140 mg/dl at screening) compared to consumption of the control product.
The purpose of the study is to evaluate whether the addition of Diamel, a nutritional supplement, to hypocaloric diet and exercise could improve the histological results (steatosis, necro-inflammatory activity and fibrosis), insulin resistance, aminotransferase levels and anthropometric measures in comparison with a placebo-controlled group with hypocaloric diet and exercise during 52 weeks of treatment in patients with nonalcoholic steatohepatitis.
The incretin effect is markedly reduced in patients with type 2 diabetes. Data support the notion that this deficiency is a consequence of the diabetic state. However, the impact of insulin resistance on the incretin effect in obese individuals who uphold a normal glucose tolerance (NGT) despite their insulin resistant state remains to be elucidated. The primary aim of the present study is to evaluate the separate impact of one of the cornerstones of type 2 diabetic pathophysiology, namely insulin resistance, on the incretin effect in lean and obese patients with type 2 diabetes and in two matched normal-glucose tolerant groups of healthy control subjects.
Obese individuals have fewer striatal dopamine type 2 receptors (DRD2) than normal weight individuals. Lower DRD2 levels are associated with addiction and a decreased sense of pleasure.Obesity is also associated with insulin resistance (poor insulin action).We propose that insulin resistance and low DRD2 are associated. Using PET imaging,we aim to determine DRD2 binding potential (BP) in the brain is associated with insulin resistance and neuroendocrine hormone levels. Obese participants will be compared to lean, gender and age similar participants. We also aim to determine the effect of caloric restriction on DRD2 BP in obese subjects
The main purpose of this project is to investigate the effects of an exercise program on arterial function and cardiovascular diseases risk factors in obese and lean pre-pubertal children. This information will be used to underpin prevention strategies to reduce cardiovascular diseases in overweight youth.
Clearly the effects of diet and exercise are beneficial for obese persons, but the underlying mechanisms for the improvements in metabolic health are not completely clear. Although mounting evidence suggests that alterations in lipid metabolism in persons with abdominal obesity are associated with a several medical complications, including diabetes, little is known about the factors responsible for this effect. The project in this application is designed to examine how the addition of endurance exercise training to a weight-loss program alters whole-body fatty acid availability, uptake, and oxidation as well as the expression of cellular factors that regulate these processes. In addition, we will evaluate whether these alterations are associated with improvements in insulin sensitivity. In the end, these experiments will provide insight into the cellular and whole-body adaptations in fatty acid metabolism in response to weight-loss and exercise training that may lead to enhancement of insulin sensitivity. Identifying relationships between gene expression, whole-body fatty acid metabolism and clinical outcome measurements, such as insulin sensitivity, may lead to improvements in the therapeutic and/or the preventative approach to obesity and its co-morbidities.
Recently EPO receptors have been found in human muscle tissue, but what is still not known is the physiological role of these receptors. In this study the researchers want to investigate if there is any effect of a acute administration of EPO on insulin resistance and/or substrate metabolism in muscle tissue.
The purpose of this study is to examine whether there is a causal relationship between insulin resistance and/or glucose intolerance in the development of a defect incretin effect.
