Integrating the Genetic and Metabolic Faces of Obesity
Insulin ResistanceObesity1 moreThe goal of this study is to determine why some obese individuals develop insulin resistance and others do not. We hypothesize that an impairment in differentiation of fat cells (adipocytes) is responsible for the development of insulin resistance in select obese individuals. This study will evaluate obese individuals at baseline with respect to characteristics of adipocytes, including gene expression, and will then entail randomizing subjects to either weight loss or treatment with an insulin sensitizing drug (pioglitazone). Changes in insulin resistance will be associated with changes in adipocyte morphology and gene expression.
The Incidence and Treatment of Insulin Resistance Among Men With Erectile Dysfunction
Erectile DysfunctionMetabolic Syndrome1 moreDetermine if men with erectile dysfunction (ED) are more likely to have insulin resistance compared to healthy controls.
Examining the Link Between Trace Elements and Cardiovascular Disease Risk Factors in Young Adults...
Cardiovascular DiseasesMetabolic Syndrome X3 moreCardiovascular disease (CVD) affects millions of people in the United States; each year, more people die from CVD than from any other disease. There are many dietary and lifestyle factors that may increase the risk of developing CVD. Preliminary research has shown that the presence of certain trace elements may be associated with the development of CVD. This study will examine toenail clippings and laboratory data to evaluate the link between trace elements and CVD risk factors in young adults.
A Study of the Function of Hormones Present In Taste Buds
DiabetesObesity2 moreThe purpose of this study is to find out whether the hormones in the taste buds are affected by tasting and eating food, and also whether these hormone levels are affected by an increase in body weight or type 2 diabetes.
Epidemiology of Stress and the Metabolic Syndrome
Cardiovascular DiseasesHeart Diseases5 moreTo examine the effects of psychological stress on the metabolic syndrome.
Behavioral Factors in Coronary Heart Disease
Cardiovascular DiseasesHeart Diseases2 moreTo elucidate the role of biobehavioral factors in the etiology, pathogenesis and course of coronary heart disease (CHD) and to use this knowledge to devise more effective prevention, treatment and rehabilitation approaches.
Genetics of the Metabolic Syndrome in Japanese Americans
Cardiovascular DiseasesCoronary Disease6 moreTo investigate the genetic influence of candidate gene polymorphisms on risk factors for the metabolic insulin resistance syndrome in Japanese American sibships and kindreds. The original grant in 1994 had as its objective to understand the genetic epidemiology of coronary heart disease (CHD) risk factors in Japanese- American families with probands living in Seattle, Washington.
Study of Metabolic Homeostasis in Chinese
HealthyMetabolic SyndromeIn this open-label, acute intervention study, we will recruit 120 sex-matched participants aged 20-70 years (100 normal or overweight/obese subjects and 20 Mets subjects). They will be assigned to one of the six groups according to age, BMI and with and without MetS and have a standardized mixed macronutrient tolerance test (MMTT) by orally administered a 400-ml beverage (75g glucose, 60g lipid, and 20g protein). Fasting and postprandial blood, and urine and fecal samples will be collected. The primary aim is to establish a more comprehensive system to quantify different aspects of metabolic health based on fasting and postprandial data. The study protocol has been approved by the Ethics Committee of Shanghai Institutes for Biological Sciences.
Sympathetic Activity and Cardiometabolic Complications
Catecholamine; OverproductionCatecholamine; Secretion6 moreRecent studies on catecholamine physiology have shown a direct correlation with arterial hypertension, overcoming the exclusive role in the diagnosis and follow-up of chromaffin tumors. Nevertheless, in literature, few studies explore and reveal the utility of testing metanephrines for the evaluation of sympathetic activity and its associated cardiometabolic complications in patients with essential hypertension.
Developing and Testing a Technology-Based Translation of the DPP to Address Prediabetes in a Primary...
PreDiabetesMetabolic Syndrome1 moreDPPFit is a Healthy Lifestyle Intervention designed to reformat the effective strategies of the Diabetes Prevention Program (NDPP) into a tool for use in a primary care setting. DPPFit is a 16-week technology-based intervention for diabetes prevention. In keeping with the National DPP educational sessions, the intervention weeks follow the order and presentation of the N-DPP 16 session topics. The goal is to develop a pragmatic translation of the DPP that is effective in the real-world setting of primary care clinic. The hope is that in doing so, those at risk of developing type II diabetes mellitus will have evidenced-based prevention methods at their disposal.
