Filter by:Raised plasma Homocysteine (Hcy) was 1st proposed as a cause of vascular pathology in patients with inherited disorders of Homocysteine metabolism.leading to the hypothesis that individuals with slight to moderate elevated levels of Homocysteine may have an increased hazard for vascular disease. As an amino acid with a reactive sulfhydryl group, homocysteine has been proposed to intermediate vascular inflammation and damage by stimulating oxidative stress secondary to reactive oxygen species accumulation. which in turn leads to an rise in cardiac and vascular disease risk by stimulating endothelial dysfunction, smooth muscle cell proliferation, and vascular calcification. Consistent with this hypothesis, hyperhomocysteinemia a has been associated with an increased risk for coronary heart disease (CHD), heart failure, atrial fibrillation, stroke, and mortality.
The objective of the trial is to assess the effect of single subcutaneous doses of dasiglucagon versus placebo on post-prandial plasma glucose nadir following a Mixed Meal Test in Roux-en-Y Gastric Bypass (RYGB) subjects
The investigators of the study want to investigate the complex interactions between glucose metabolism, food intake/weight loss, and different appetite regulating hormones after ESG in comparison with conventional laparoscopic sleeve gastrectomy (LSG).
The purpose of this study is to determine the safety, tolerability, action and effectiveness of repeated doses of Erythrocyte Encapsulated Thymidine Phosphorylase (EE-TP) for the treatment of patients with Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE). MNGIE is a rare inherited disease that mainly affects the digestive and nervous system and is caused by a defect in the function of an enzyme called thymidine phosphorylase. This loss of function causes certain molecules (thymidine and deoxyuridine) to accumulate in cells which leads to toxic damage to these cells. The disease can be confirmed by detecting variations (mutations) in the thymidine phosphorylase gene (TYMP). Currently there are no specific treatments for patients with MNGIE, whose effectiveness has been shown through clinical trials. The potential treatment for MNGIE offered in this trial is an enzyme replacement therapy, i.e. replacing functional thymidine phosphorylase. This treatment uses the patients own red blood cells in which thymidine phosphorylase is encapsulated to produce EE-TP (the study drug). EE-TP is created using a machine named a Red Cell Loader (RCL) and is then administered back to the patient.
There is a growing body of evidence suggesting low water intake and elevated levels of the hormone vasopressin exacerbate glucose regulation. This project will examine the physiological mechanism by which low water intake impairs glucose homeostasis. In the current proposal we aim to: 1) quantify the degree of glucose impairment as a response to elevated vasopressin due to low water intake and 2) identify the physiological mechanism by which elevated vasopressin, as a response to low water intake, impairs glucose regulation
It is believed that important brain centers send signals through the vagus nerve to the liver to suppress the amount of glucose (sugar) that gets produced. People who have received liver transplants have had their vagus nerve cut during transplantation, and many of these individuals have diabetes at one year post-transplant. The goals of this study are: to see whether metabolic control centers in the brain can still be activated normally with the medication diazoxide in patients who have had a liver transplant, and to understand whether disrupting the vagus nerve would result in excess glucose being produced by the liver (ie. a potential mechanism for why these patients develop diabetes).
This study will assess the effect of treatment for hepatitis C virus (HCV) on cardiovascular disease risk. The study will enroll men and women who are infected with HCV and have underlying metabolic disease. All participants will receive a 12-week course of an HCV treatment (elbasvir/grazoprevir). Cardiovascular disease risk will be evaluated at baseline, week 4 on treatment, 12 weeks post-treatment, and 52 weeks post-treatment through noninvasive measurements of endothelial function, insulin resistance, liver fibrosis and steatosis, and circulating blood biomarkers.
Caffeine containing energy drinks (CCED) are beverages that typically contain mixtures of simple sugars, caffeine and may contain vitamin, mineral and/or herbal preparations. In Canada, the consumption of CCEDs among adolescents is a regular occurrence and a common part of the everyday diet. Contributing to the obesity epidemic in youth is the consumption of energy drinks; yet no data on the metabolic responses to CCEDs exists. This study will examine the metabolic implications of CCED consumption in adolescents, aged 13-19 years. The investigators hypothesize that CCEDs will impair glucose tolerance by ~30% in lean adolescents and the primary cause of the insulin resistance will be caffeine. Obese individuals will experience a similar level of glucose impairment, but a greater rise in blood glucose compared to their lean counterparts (i.e. higher starting glucose level). For many, this additional, caffeine-induced rise will expose them to hyperglycemia, putting some individuals in the glucose intolerant or transient diabetic range. It is hypothesized that continued metabolic insult resulting from CCEDs may predispose susceptible individuals to chronic metabolic diseases later in life. The investigators will also examine the genetic basis of caffeine-induced glucose intolerance. This gene-diet interaction could explain why caffeine may be much more metabolically harmful for some individuals compared to others. The study of 'metabolomics' will also be utilized to analyze caffeine and caffeine metabolites such as theobromine, theophylline, and xanthine. This will be accomplished using Nuclear Magnetic Resonance (NMR) spectroscopy. Results from this study will have the potential to alter current perceptions that CCED are 'harmless' and will have far reaching implications for both medical professionals and legislators alike.
Development of a new MS-based biomarker for the early and sensitive diagnosis of Tyrosinemia type 1 from blood (plasma)
The aim of this study is to compare the effect of fixed and free combination of atorvastatin/perindopril/amlodipine on blood pressure and lipid levels.
