Filter by:The pathogenesis of nonalcoholic fatty liver disease has not been fully elucidated. The most widely supported theory implicates insulin resistance as the key mechanism leading to hepatic steatosis, and perhaps also to steatohepatitis. Selenoprotein P(SeP) is a secretory protein primarily produced by the liver. Previous studies demonstrated that SeP, a liver-derived secretory protein, causes insulin resistance. Therefore, the purpose of this study is to determine the different Sep levels between healthy normal group and NAFLD group.
The aim of the present study was to investigate the effects of Gynostemma Pentaphyllum tea on insulin sensitivity in drug-naïve type 2 diabetic patients.
Food products derived from cereal grains constitute a major part of the daily diet of many Americans . For example, a typical Chinese American eats rice about 9.5 times a week on an average. However, most of these foods are derived from refined grain. During the refining process grains are stripped of their bran and germ which results in depletion of several biologically active constituents including fiber, anti-oxidants, phytoestrogens and minerals. From observational studies there is evidence for a protective effect of whole-grain foods with regard to the development of type 2 diabetes. More recently, higher intake of whole grains was also associated with decreases in insulin resistance - a risk factor related to the development of type 2 diabetes. In this randomized study the investigators plan to replicate this beneficial effect of improving insulin sensitivity in patients with pre-diabetes and go a step further by exploring the potential mechanisms by which this benefit may occur. The investigators will assess the effect of consuming a whole-grain-rich diet on levels of advanced glycation endproducts (AGE), RAGE (receptor for AGE) and markers of inflammation and oxidative stress - all of which have been shown to play an important role in the pathogenesis of diabetes mellitus. The investigators will also look for correlations between the levels of these markers with insulin sensitivity to identify potential mechanisms of pathogenesis.
The study is being conducted to find out why too much fat in your blood stream may cause insulin resistance in your muscles. Insulin is the hormone, produced normally by your body, which causes your blood sugar to return to normal after you eat.
0-hypothesis: advisory support does not 1. prolong the the breast-feeding period 2. minimize the risk of obesity and metabolic dysfunction in infants of obese mothers
This study aims to explore time-dependent effects of lipid infusion an intramyocellular lipid metabolites and the induction of impaired insulin signaling.
The present study was conducted to test whether a fish gelatin supplement combined with an omega-3 polyunsaturated fatty acid supplement can exert beneficial and sex-specific effects on insulin sensitivity, glucose tolerance, indicators of insulin secretion, blood pressure, lipid metabolism, inflammation and energy intake in obese or overweight insulin-resistant men and women. The investigators hypothesis is that fish gelatin improves insulin sensitivity, glucose tolerance, lipid profile and reduces inflammation in obese or overweight insulin-resistant men and women.
This study will investigate the non-growth-hormone-dependent metabolic effects of the hormone Ghrelin in growth hormone deficient subjects by examining the insulin tolerance as well as signal proteins in fat and muscle biopsies.
Stress hyperglycemia during myocardial infarction (MI) is related to mortality at short and long term. Recent studies, however, revealed that chronic statin treatment may decrease both insulin sensitivity and secretion immediately after statin therapy initiation. This study aim was to investigate the dose-dependent effect of statins on insulin sensitivity in patients in the acute phase of MI.
The aim of this study is primarily to investigate the ability of antioxidants found in orange juice (OJ) to increase the body's sensitivity to the hormone insulin. Overweight or mildly obese women, who are otherwise healthy, will be recruited. The time commitment for subjects is ~14wks. Subjects will attend the laboratory on 5 occasions after fasting from midnight. The 1st is a medical screening. Laboratory visits 2 & 5 will take ~5hrs and will be separated by 3 months, during which time subjects will consume 250ml of an orange drink (either OJ or an orange flavoured control drink) once a day. During visits 2 & 5, subjects will have a scan to assess their %body fat using a low-dose x-ray machine, and have their insulin sensitivity measured using a technique called a 'Glucose Clamp'. During the 3hr glucose clamp, subjects receive an infusion of the hormone insulin and a glucose solution directly into their blood stream, with insulin sensitivity determined from the amount of glucose required to maintain blood glucose at normal levels. In addition, a small sample of fat tissue (about the size of a haricot bean) will be taken from underneath the skin of the belly. Subjects will record their food intake for 3-days in weeks 3, 7 and 11 of consuming the drink, and come to the lab for visits 3&4 during weeks 4&8. Laboratory visits 3&4 repeat measurements taken in the 1st (screening) visit.
