Filter by:Magnesium is the second most abundant ion in human cells and plays fundamental roles in several enzymatic reactions: it is involved in ATP production, in the phosphorylation of proteins, in glucose metabolism and in the contraction of cytoskeleton. Several epidemiological studies demonstrated that low dietary magnesium intake is inversely associated with diabetes mellitus, hypertension and metabolic syndrome. Magnesium could be related to important haemodynamic and metabolic anomalies: at vascular level it acts as an antagonist of calcium, especially in vascular smooth muscle cells, thus its deficit could enhance vascular contraction; with regard to glucose metabolism, magnesium is involved in the physiopathological mechanism of insulin resistance, through a reduction in cellular uptake of glucose. This condition and the subsequent compensatory hyperinsulinemia can ultimately lead to increased synthesis of proinflammatory cytokines and to endothelial dysfunction. Thus, magnesium depletion and subsequent alterations can increase the risk of developing vascular disease such as atherosclerosis and has been associated with cardiovascular events. Several clinical trials have explored the possible beneficial effect of magnesium supplementation on blood pressure, plasma lipids and insulin resistance but the results are often contradictory. One of the possibilities for these unclear results could be that in some of them the interventions started too late when haemodynamic and metabolic changes are more difficult to revert. The investigators hypothesis is that magnesium supplementation in a population at increased genetic risk of developing metabolic syndrome but without it could improve blood pressure and the other metabolic syndrome related components. Thus, the aim of the present study is to evaluate the effect of oral supplementation of magnesium (16.2 mmol/day of magnesium pidolate) on metabolic syndrome's components in a sample of 15 subjects who are at increased risk of developing metabolic syndrome since have a positive familiar history of type II diabetes mellitus and/or metabolic syndrome(AHA/NHLBI criteria).
The purpose of this study is to determine whether probiotic treatment of overweight volunteers consuming high fat diet is able to reduce plasma lipopolysaccharide concentration.
The study is a survey to answer the specific question, "What is the prevalence of metabolic syndrome in maintenance hemodialysis patients?" Metabolic syndrome is a cluster of conditions that increase an individual's risk for developing cardiovascular disease and diabetes.
The investigators hope to learn about the effects of soy nuts on markers of health. When some people eat soy foods, their gut bacteria make equol. Equol is a soy metabolite (small molecule made during metabolism). The investigators will be testing blood samples to determine if markers of health are different for people who make equol versus people who do not make equol.
The purpose of this study is compare the effects of consuming glucose- and fructose-sweetened beverages on appetite, body weight, body fat, and the amount of energy the body burns as well as effects on blood pressure, hormones, blood triglycerides and cholesterol, and the body's sensitivity to the insulin.
Cardiovascular disease (CVD) represents the first cause of mortality in industrialized countries such as Canada and the United States. In that regard, it is being increasingly recognized that a significant proportion of CVD events may be attributable to the presence of a cluster of metabolic and physiological perturbations defined as the metabolic syndrome (MetS). The National Cholesterol Education Program- Adult Treatment Panel III (NCEP-ATP III) has recently proposed a clinical definition to identify individuals with the MetS. This definition is based on the presence of at least three of the following five characteristics: 1- abdominal obesity, 2- hypertriglyceridemia, 3- reduced plasma HDL-C levels, 4- high blood pressure, 5- high fasting blood glucose levels. Recent data have suggested that the MetS based on this definition was associated with a 2 to 5 fold increase in the risk of CVD in men as well as in women. These are alarming figures since it has been suggested that as much as 35 to 45% of female aged > 65 years in the US may have the MetS. It is therefore imperative to develop new preventive strategies that will be efficacious in attenuating the impact of the MetS on the progressing rates of CVD in women. In that context, there is accumulating evidence to suggest that milk and dairy products may beneficially modify several components of the MetS. However, most of the available data to date are based on observational studies or interventional studies with minimal nutritional control. Thus, metabolically controlled studies that document the impact of milk consumption on cardiovascular risk factors associated with the MetS in women defined a priori as having the MetS are utterly lacking. The purpose of this study was to investigate the impact of milk consumption on features of the MetS in menopausal women presenting one or more features of the MetS.
The study is designed to answer the following questions: 1. Is hypogonadism a cause for the metabolic syndrome ? 2. What is the effect of testosterone replacement on the metabolic parameters ?
The purpose of this study is to evaluate the influence of hyperuricemia treatment compared with placebo on participants with high risk of hypertension and metabolic syndrome.
The aim of this study is to explore if a 8-weeks dietary intervention with polyphenols and omega 3 fatty acids (alone or combined) may be effective on postprandial lipids metabolism and other cardiovascular risk factors in people at high cardiovascular risk.
Insulin resistance is a common condition that can lead to type 2 diabetes. One of the commonly prescribed diabetes medications, called rosiglitazone, works by decreasing insulin resistance. Rosiglitazone appears to work on fat cells. Animal studies suggest that rosiglitazone may work by increasing blood vessel growth in fat cells. The purpose of this research is to see if rosiglitazone also increases blood vessel growth in human fat cells. The investigators will compare results from before and after being on rosiglitazone for 6 weeks.
