Filter by:This is a pilot study to determine the optimum time and dose to draw blood samples using a tracer for HDL kinetics.
The main goal of the present study was to provide a technical basis for future studies assessing the role of cardiac lipids. More specifically, non-invasive MR-Spectroscopy (MRS) techniques will be used in this study to: 1. assess the methodological reproducibility of MRS-measurements of cardiac lipids in humans 2. investigate physiological variations of cardiac lipids by measuring day-to-day changes under identical conditions 3. determining diurnal variations of cardiac lipids in humans
A high-calcium intake can accelerate fat loss under energy-restricted diets. Part of this may be due to a shift in substrate metabolism where there is an increase in the rate of fat oxidation. However, whether high-calcium intake can influence substrate metabolism during exercise is not known. Accordingly, we aim to investigate the effect of 2 weeks of high-calcium intake on substrate metabolism during exercise.
Background: - Glucocorticoids are primary stress response hormones released from the adrenal gland when an individual is under stress. Chronic or ongoing elevation of these hormones due to prolonged stress or medical treatments can have numerous harmful effects. Researchers are interested in learning more about how these hormones affect cell growth, development, and death. To study glucocorticoid hormones, researchers plan to use the medication dexamethasone, which affects the parts of cells that respond to glucocorticoid hormones. Objectives: - To study glucocorticoid stress hormones in healthy individuals before and after receiving dexamethasone. Eligibility: - Healthy individuals at least 18 years of age. - Participants must not be using certain medications that may affect the dexamethasone test, including hormonal contraception, steroid-based drugs, and some antidepressants. Design: - This study will require an initial screening visit and a second study visit. The visits are estimated to require about 1 to 2 hours of participation over a period of up to 14 days. - Participants will be screened at visit 1 with a full physical examination and medical history, and an initial blood sample for testing. - For visit 2, participants will be asked to abstain from all food and drinks except for water for 12 hours before the appointment, and will take one tablet of dexamethasone 9 hours before the appointment. - Participants will have a second blood sample taken during visit 2, and will receive a snack after the blood is drawn.
EDUFIT is a group-Randomized Controlled Trial specifically designed to enhance physical fitness and other health-related factors in a school setting in adolescents.
The purpose of this study is to determine the partitioning of exogenous lipids in the postprandial period while a study of overfeeding. The method is based on the incorporation of a stable isotopic tracer (d31_palmitic acid, d31_C16) in lipoprotein triglycerides (TG-CHYLOMICRON and TG-VLDL) and in free fatty acids (FFA).
It has been widely documented that fructose overfeeding increases plasma triglycerides and hepatic de novo lipogenesis, and impairs insulin sensitivity in healthy male volunteers. The effect of gender on the metabolic responses to fructose remains an important open question, however. The objective of this study is to compare the effect of an acute oral fructose load on carbohydrate and lipid metabolism in healthy young males and females.
The purpose of this study is to evaluate the metabolic and anti-inflammatory effects of eccentric endurance exercise and to compare them with those of concentric exercise in healthy sedentary individuals.
This study is a randomised, placebo-controlled study of the effect of treatment with the HMG-CoA reductase inhibitor, pravastatin, in HIV-infected, protease inhibitor treated patients with high serum cholesterol. We hypothesise that pravastatin will result in greater reductions in cholesterol than placebo when used in conjunction with appropriate dietary advice.
