Filter by:Gymnema sylvestre has demonstrated promising effects in the treatment of obesity, dyslipidemia, hypertension, insulin secretion, among others. The above mentioned findings show that Gymnema sylvestre has an excellent potential for the prevention and treatment of metabolic syndrome.
The purpose of this study is to assess the safety, tolerability, and the effect of food on KQ-791. Each participant may receive up to 3 single doses of KQ-791 (at up to 3 different dose levels) and 1 placebo dose over the course of the study. Up to 6 escalating dose levels may be studied, in two distinct groups or cohorts.
The metabolic syndrome is a high prevalence disease worldwide. About a quarter of the adult population suffers from the disease and predispose the onset of diseases like cardiovascular disease and diabetes mellitus type 2. The first line of treatment for metabolic syndrome is diet and exercise but patients have a low attachment to the treatment, so pharmacologic therapy is required. There is no a single drug that could help to the treatment of all metabolic syndrome components. Irvingia gabonensis, better known as African mango, is widely consumed in central and western Africa, mainly the fruit and seeds. Besides being part of the diet of African the seeds have been used for the treatment of diseases such as dysentery, diabetes and as an analgesic. Resent investigations have demonstrated that an extract of African mango seeds induce significantly weight loss in subjects with obesity, and also improves some biochemical parameters such as glucose and the lipid profile. The aim of this study is to evaluate the effect of Irvingia gabonensis on metabolic syndrome, insulin secretion and insulin sensitivity.
Advanced glycation end products (AGE) result from a chemical reaction between the carbonyl group of reducing sugar and the nucleophilic NH2 of a free amino acid or a protein; lysine and arginine being the main reactive amino acids on proteins. Following this first step, a molecular rearrangement occurs, rearrangement of Amadori resulting to the formation of Maillard products.
The overall objective of the current proposal is to strengthen the putative link between FFA induced insulin resistance and atherosclerotic vascular disease (ASVD). To this end, the investigators will test the following hypotheses: 1) that FFA induced activation of protein kinase C βII (PKC β II) and δ and other serine kinases such as IκB kinase (IKK) in human muscle is associated with a decrease in insulin stimulated tyrosine phosphorylation of the insulin receptor substrate-1 (IRS-1) and of IRS-1 associated phosphatidylinositol 3 (PI3) kinase; 2) that these changes precede the development of insulin resistance; 3) that the decrease in IκB-α results in activation of nuclear factor κB (NFκB) and the expression of adhesion molecules and cytokines; 4) that PKC and IKK are involved in producing insulin resistance and activation of the IκB/ NFκB pathway and lastly 5) that the same mechanisms operative in healthy volunteers are also operative in patients with T2DM.The investigators will test these hypotheses in normal (current) and diabetic volunteers (previously completed) . Euglycemic-hyperinsulinemic clamps will be performed with and without co-infusion of lipid plus heparin (to raise FFAs) and by obtaining serial muscle and fat biopsies and blood samples will be obtained for measurement of substrates, hormones, enzymes and metabolites.
The metabolic syndrome is characterized by the presence of overweight/obesity, insulin resistance, hyperglycemia, dyslipidaemia and hypertension and an inflammatory state, which together increase the risk of developing cardiovascular disease (CVD) or diabetes mellitus type 2 (DM2). It is also characterized by a decreased insulin sensitivity, namely, lower ability of insulin to metabolize glucose, key in the physiopathogeny of disease process. In the search for a pharmacological agent that can attend more components of the metabolic syndrome and above all improve insulin sensitivity to effectively prevent the development of CVD and DM2, ursolic acid is a promising compound. Ursolic acid is a pentacyclic carboxylic acid present in medicinal herbs, parts of some fruits like apple peel, and plants such as rosemary. There is scientific evidence of important benefits of ursolic acid level in vitro and in vivo on insulin, metabolism of lipids and glucose, as well as on the body weight and metabolic parameters. However, the results are not clear and the mechanisms are not fully elucidate. The aim of this study is to evaluate the effect of ursolic acid on the insulin sensitivity and metabolic syndrome.
The purpose of this study is to investigate the effects of dietary exposure to artificial sweeteners on taste sensitivity, preference and brain response in adults. The investigators hypothesize that dietary exposure to artificial sweeteners (sucralose) will decrease sensitivity to taste, shift preference of sweet and savory taste to a higher dose, and reduce brain response in amygdala to sweet taste compared to sucrose.
A Phase 2a, randomized, double-blind, placebo-controlled, multi-center study of cenicriviroc (CVC) to be conducted in approximately 50 adult obese subjects [body mass index (BMI) ≥ 30 kg/m^2] with prediabetes or type 2 diabetes mellitus and suspected NALFD.
The term prediabetes has been used to encompass the first alterations on glucose metabolism such as impaired fasting glucose and glucose intolerance, and its early detection and treatment could prevent the appearance of diabetes mellitus type 2, a high prevalence disease worldwide. Artemisia dracunculus, also known as estragon, has been used in Ayurvedic medicine for the treatment of diabetes. Different in vitro and in vivo studies have shown that Artemisia dracunculus increases insulin signaling and improves insulin sensitivity. The aim of this study is evaluate the effect of Artemisia dracunculus on glucose intolerance, insulin sensitivity and insulin secretion.
The purpose of this study is to determine whether pharmacologic inhibition of Toll-like receptor 4 (TLR4) with eritoran for injection (E5564) prevents lipid-induced insulin resistance in lean, normal glucose tolerant (NGT) subjects.
