Filter by:This study will investigate the effects of 6 week Nicotinamide Riboside supplementation (1000 mg/day) on metabolic health in healthy (pre)obese humans. The primary objective will be hepatic and whole body insulin sensitivity. Secondary objectives, to provide information about the underlying mechanism, will be muscle mitochondrial function, brown fat activity, ectopic lipid accumulation, energy metabolism, cardiovascular risk parameters, body composition and acetylcarnitine levels.
This is a single blind randomised controlled clinical trial in uncontrolled type 2 Diabetes mellitus patients on oral glucose lowering agents, and naive to incretinomimetic. Participants will be randomised in two Arms : arm 1 receiving Liraglutide at 1,2 mg/day and arm 2 Vildagliptine at 100mg/day over 14 days. The two arms will be compared for 14-day changes in insulin secretion and insulin sensitivity.
This study was aimed at assessing the effects of non-surgical periodontal treatment (NSPT) of chronic periodontitis on insulin sensitivity, glucose tolerance, and serum C-reactive protein(CRP) level amongst non-diabetic subjects.
The primary aim of the current study is to clarify whether serum vitamin D levels [25(OH)D3] have a temporal association with insulin resistance and/or insulin sensitivity in PCOS women versus healthy ones. To achieve this aim, the investigators will conduct a prospective observational study involving obese and lean PCOS women in comparison to obese and lean healthy subjects living in Cairo, Egypt.
The purpose of this study is to determine the effects of a low carbohydrate diet vs a low fat diet on improvement in aminotransferases, hepatic fat infiltration, markers of inflammation, insulin resistance, and body composition in obese adolescents with non-alcoholic fatty liver disease (NAFLD).
The study team will investigate the racial differences in the metabolic and clinical responses to Medium chain triglycerides (MCT) between African American and Caucasian American subjects.
Growth hormone (GH) is essential for longitudinal bone growth and somatic development. These protein anabolic effects require sufficient nutritional supply. During fasting and caloric restriction GH predominantly promotes fat metabolism. GH counteracts the effect of insulin in many tissues, of which insulin-stimulated glucose uptake in skeletal muscle has been most extensively studied. Substrate competition between elevated free fatty acids and glucose is suggested as a mechanism, and this hypothesis can be tested mechanistically by means of acipimox, which is a nicotinic acid that suppresses the fat metabolizing effects of GH. The hypothesis is, that the suppressive effect of GH on insulin-stimulated glucose uptake in skeletal muscle is obviated by acipimox-induced inhibition of fat metabolism. In order to investigate this, eight adult hypopituitary patients with documented GH-deficiency will be studied in the presence and absence of GH and acipimox, respectively, and biopsies from skeletal muscle and subcutaneous adipose tissue will be analyzed. Knowledge of the effects of growth hormone and fat metabolism can in shot-sight as well as in long-sight have great importance for the understanding of growth disorders from overweight and type 2 diabetes to malnutrition and eating disorders.
The aim of this research is to explore changes in peripheral/cerebrovascular function and insulin sensitivity after a 7-day combination of physical activity reduction (-50% steps per day) and overfeeding (+50% kcal per day, comprising 65% fat) in healthy male volunteers, and examine whether daily intake of tea can prevent such changes.
The Metabolic Syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers the disease. Banaba has shown evidence that has on metabolic syndrome, insulin sensitivity and insulin secretion. The investigators hypothesis was that the the administration of resveratrol modifies the metabolic syndrome, insulin sensitivity and insulin secretion.
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age. Hyperandrogenism is the central feature of PCOS. Studies on isolated ovarian theca-interstitial cells indicate that resveratrol, a natural polyphenol, reduces androgen production. This study is designed to evaluate the endocrine and metabolic effects of simvastatin and resveratrol on PCOS. Methods: A randomized (1:1) double-blind, placebo-controlled trial will evaluate the effects of administering 20 mg of simvastatin daily and 500 mg of resveratrol daily, or administering 20 mg simvastatin and the placebo to women with PCOS at an academic hospital. PCOS is defined according to the Rotterdam criteria. Evaluations are performed at baseline and repeated after 3 and 6 months of treatment. The main outcome is a change of the serum total testosterone and the fasting insulin level.
