Active clinical trials for "Metabolic Diseases"

The study will investigate if consumption of amino acid mixtures results a change in glycemic response of carbohydrate (white rice) and insulinemic response at different doses and timing (before consumption of carbohydrate).

The purpose of this study is to assess the effects of acute beetroot juice supplementation on exercise performance and cardiometabolic health in obese individuals with secondary cardiometabolic complications. Additionally, we will determine if the ergogenic health benefits of beetroot juice is due to the nitric oxide compound within the product, the antioxidant compound within the product, or a combination of the two compounds.

Wholegrain fibre is known to affect on the gut health, but also may cause intestinal discomfort. Thus, many individuals may avoid the consumption of whole grain cereals in spite of their known health benefits, and may in this regard consume more restricted diets. In the preset study the aim was to technologically modify the cereal fibres to improve its usability and to maintain its health beneficial properties. The objective was to investigate intestinal fermentation of grain dietary fibre and associated effects on gut-mediated metabolic health, such as immunological health and adipose tissue function. The hypothesis was that whole grain products maintain their original beneficial health effects and may be better tolerable when the bran is technologically modified. Additionally, it was hypothesized that gut-mediated bioavailability of plant cell wall compounds and their metabolites affect the metabolic health through their immunomodulatory effects.

Delinieation of GIP's effects during an oral glucose tolerance test (OGTT) in humans using GIP receptor antagonisation.

It has been recognized lately that sepsis and inflammation has an important impact on lipid metabolism and that the extent of hypocholesterolemia may even be a marker of severity of illness. However, the interplay between inflammation and the marked changes in lipid metabolism remain to be sufficiently understood. Importantly, the exact kinetics of lipid parameters in inflammatory conditions are yet to be explored. This study aims to investigate the interaction between inflammation and lipid metabolism using the human endotoxin model (LPS infusion) in ten healthy volunteers in a single blinded randomized placebo controlled cross-over design.

Accumulation of intramyocellular lipids (IMCLs) due to increased supply of fatty acids can induce defects in the insulin signaling cascade, causing skeletal muscle insulin resistance. However, the causes for muscle insulin resistance are not well understood. The association of elevated IMCLs and insulin resistance has been shown in obese humans and individuals with type 2 diabetes as well as several animal models of insulin resistance. Despite the strong relationship between IMCLs and insulin resistance, this suggested relationship disappears when well-trained endurance athletes are included into this consideration as this group is highly insulin sensitive. This metabolic enigma has been termed the 'athlete's paradox'. The aim of this project is to resolve the mechanisms contributing to the athlete's paradox.

Glucose-dependent insulinotropic polypeptide (GIP) is a gut-derived incretin hormone that affects glucose, lipid and bone metabolism. Secretion of GIP into the blood stream from enteroendocrine cells is stimulated bu nutrients in the gut lumen and results in potentiation of glucose stimulated insulin secretion from the pancreas. The objective of this study is to investigate the physiology of GIP(1-30)NH2 in humans with insulin secretion as the primary endpoint. Furthermore the effects on on plasma/serum levels of glucagon, C-peptide, glucose, bone markers (CTX and P1NP) will be measured.

This study tested the hypothesis that ground beef high in monounsaturated fat (MUFA) and low in saturated fat (SFA) would increase the high-density lipoprotein-cholesterol concentration and low-density lipoprotein particle diameter. In a crossover dietary intervention, 27 free-living normocholesterolemic men completed treatments in which five 114-g ground beef patties/week were consumed for 5 weeks with an intervening 4-week washout period. Patties contained 24% total fat with a MUFA:SFA ratio of either 0.71 (low MUFA, from pasture-fed cattle) or 1.10 (high MUFA, from grain-fed cattle).

This study is aimed at evaluating the hypoglycemic effects of a dietary supplement that associates the properties of two inositols (myo-inositol and D-chiro-inositol) in the ratio 40:1 to Gymnema sylvestre, alpha-lactalbumin and zinc.

Negative-calorie diet is among the popular dieting guides for weight loss; however, there is still little knowledge about this method. The present study aimed to determine the effects of negative-calorie diet on weight loss and lipid profile, and to compare its efficiency with low-calorie diet in men.
