Filter by: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.
In this study the investigators want to compare glucose handling (insulin secretion and insulin sensitivity) in 100 persons with low and 50 persons with normal-high levels of vitamin D, using a hyperglycemic clamp technique, were sugar is given intravenously for 3 hours in order to keep the blood sugar level at 10 mmol/L. Those with low vitamin D levels will be randomized to treatment with vitamin D3 (cholecalciferol) 40 000 IU/week or placebo for 6 months before a new clamp is performed. The study hypothesis is that persons with low vitamin D levels have impaired glucose handling which might be improved by vitamin D supplementation.
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.
This clinical, randomized, cross-over study in obese healthy subjects aimed to analyse the acute effects of the incretin hormon Glucose Dependent Insulinotropic Polypeptide (GIP) on metabolic parameters and gene expression in subcutaneous adipose tissue.
The purpose of this study was to evaluate the effects of 12 weeks' increased daily physical activity versus diet restriction on regional fat distribution, insulin sensitivity and adipokines including retinol binding protein-4 (RBP-4), leptin, adiponectin, and a new marker, adiponectin to leptin ratio (AL ratio), in type 2 diabetic women.
Persistent low-grade inflammation and impaired fibrinolysis, are independent predictors of several chronic diseases highly prevalent in the older Veteran population including cardiovascular disease (CVD), stroke, and diabetes. Inflammation is likely to be a causative underlying mechanism of insulin resistance. Lifestyle changes such as weight loss and physical activity are advocated for the treatment of these chronic diseases and endpoints, and data are emerging which suggest that these treatments may be beneficial, in part, due to their anti-inflammatory effects. Identification of effective therapies that reduce chronic inflammation for Veterans is important given the widespread adverse health effects of a chronically elevated inflammatory state.
This study will include subjects with an abnormal glucose tolerance test. Using a crossover design, we will evaluate the insulin sensitivity and intracellular lipid content of the heart, liver and skeletal muscle of subjects before and after therapy with Rosiglitazone and placebo. We hypothesize that Rosiglitazone will improve insulin sensitivity in association with reduced muscle lipid content that may arise either from increased lipid oxidation or enhanced storage of fat in adipose tissue.
The purpose of this research study is to determine if adding Metformin, a drug that reduces insulin resistance, to birth control pills will reduce the risk of developing type 2 diabetes, high blood pressure. high lipid levels and heart disease in women with PCOS
