Filter by:The objective of this trial is to examine the long-term effects of a diet low in carbohydrates, as compared to one low in fat, on cardiovascular disease risk factors, including blood pressure (BP), body weight and composition, serum lipids, plasma glucose, insulin, adipocytokines (adiponectin, leptin, resistin), and C-reactive protein (CRP) among obese adults. The investigators will test the following hypotheses: Hypothesis 1: Compared to a low fat diet, a diet low in carbohydrates will reduce systolic and diastolic BP over 12 months; Hypothesis 2: Compared to a low fat diet, a diet low in carbohydrates will reduce body weight, total percent body fat, and waist circumference over 12 months; Hypothesis 3: Compared to a low fat diet, a diet low in carbohydrates will reduce serum levels of LDL-cholesterol and triglycerides and increase serum levels of HDL-cholesterol over 12 months; Hypothesis 4: Compared to a low fat diet, a diet low in carbohydrates will reduce plasma levels of glucose and insulin levels over 12 months; and Hypothesis 5: Compared to a low fat diet, a diet low in carbohydrates will reduce plasma levels of leptin, resistin, and CRP and increase plasma levels of adiponectin over 12 months.
Combinded therapy with folic acid and enalapril may significantly decrease plasma total homocysteine level and had beneficial effect on blood pressure reduction and glycometabolism.
The primary purpose of the study is to demonstrate a blood pressure lowering effect of CasiGold and CasiMax in subjects with high-normal blood pressure or mild hypertension. The secondary purpose is to collect human safety data after treatment with CasiGold and CasiMax, to gain insight into potential mechanisms by measurement of renin and angiotensin I and II, and to evaluate the genetic determinants of the individual BP lowering response by measurement of specific genetic polymorphisms.
To determine racial/ethnic differences in preference for group visits in veterans with poorly controlled hypertension (State 2 hypertension) and determine the effect of group visits on health outcomes among veterans with poorly controlled hypertension.
The objective of this intervention study is to examine the effect of whole cow's milk versus infant formula as primary milk sources with or without supplements of n-3 LCPUFA for growth, nutritional status, development, risk factors for later diseases and the impact on the intestinal microbiota and inflammation in 9 - 12 months old infants.
This is a research project to test two study techniques among healthy adults. The procedures look at how blood flow is controlled by substances in blood vessels.
The purpose of this study is to determine the amount of cardiac work as measured by heart rate and blood pressure during physical exertion compared to sexual activity.
