Filter by:The objectives of the proposed study are to assess whether the metabolic effects of walnut consumption depends on which food components the walnuts substitute (i.e. carbohydrates; saturated fatty acids) and whether it is important to consume walnuts as snacks or with meals.
Evaluate the performance of a cryolipolysis system using a colder treatment parameter for non-invasive reduction of subcutaneous fat in the lateral thighs.
Background: - Genes are the instructions our body uses to function. Researchers can look for changes, or variants, in the genes. The goal of this study is to find new gene changes that lead to lipid disorders. Older research methods looked at one or a few genes at a time. Genomic sequencing looks at most of the genes at once. Genomic sequencing may find the cause researchers haven t been able to find from past methods. Objectives: - To better understand genetic causes of lipid disorders through genomic sequencing. Eligibility: - People age 2 and older with unusual lipid disorders, and their relatives. Design: - Participants will be screened with a physical exam and medical history. They will have blood taken. They may give a saliva sample. - Based on the screening test, researchers will chose 3-5 family members to perform the genomic sequencing. The sequencing will be done on a sample of DNA collected during the blood draw and saliva sample. - Participants may be invited to take part in other protocols that may involve imaging of their heart or blood vessels. They do not have to participate. If they do, they will sign a separate consent for those tests. - If a participant s family member cannot travel to the NIH, the NIH documents and consent will be reviewed during a teleconference. A blood or sputum kit will be mailed to them.
The aim of this study is to assess whether high intensive statin therapy could regress carotid atherosclerotic plaques as determined by High-Resolution Contrast Enhanced Magnetic Resonance imaging (CE-MRI). Enrolled patients have a baseline CE-MRI examination for screening carotid atherosclerotic plaques and are randomized to either low dose of Rosuvastatin (5mg) group or high dose of Rosuvastatin (20mg) group. After 26 weeks, all patients received CE-MRI examination again and each pair of baseline and follow-up CE-MRI assessments was analyzed in a blinded fashion. Moreover, lipid level and major adverse cardiovascular events are also evaluated during follow-up.
Study to Evaluate Non-Invasive Subcutaneous Fat Reduction in the Submental Area using Cryolipolysis. Healthy adult men and women with submental skin fold thickness > 1cm who desire reduction of submental fat.
Pycrinil® is a purified extract of the artichoke leaf. Artichoke leaf extract (ALE) has some clinical trial data suggesting benefit in the treatment of cholesterol disorders in several countries, but this effect has not been studied in a U.S. population. The investigators will give ALE or a placebo to overweight men and women with low "good" cholesterol to see if ALE increases their good cholesterol. The investigators will also make sure that ALE is safe.
The objective of the study is to assess the effect of two diets with different fat composition on cholesterol metabolism. The study was a randomized cross-over trial where volunteers follow two study periods with different types of meat (lean and fat red meat) separately by a ten days wash-out period. At the beginning of the study and after the study periods the following parameters are determined: anthropometric (weight, waist, circumference and body mass index), blood pressure, dietary (72-hours dietary registry) and exercise assessments and biochemical analysis (total cholesterol, triglycerides, HDL cholesterol, LDL cholesterol, apolipoprotein A1, apolipoprotein B, iron, transferring, ferritin, uric acid, glucose, HbA1c and insulin). Serum concentration of non cholesterol sterols (sitosterol, campesterol, stigmasterol, desmosterol and lanosterol) and oxysterols (24S-hydroxycholesterol, 27-hydroxycholesterol and 7α-hydroxycholestenone) were measured by High Performance Liquid Chromatography tandem Mass Spectrometry in these subjects throughout along the study in order to demonstrate the effect of different red meat on the hepatic metabolism of cholesterol.
Rationale: Increased intakes of n-3 long chain polyunsaturated fatty acids eicosapentanoic acid (EPA) and docosahexaenoic acid (DHA), mainly found in fatty fish, are recommended for the prevention of coronary heart disease. Alpha-linolenic acid (ALA, C18:3n-3) is the most common vegetable-oil based n-3 fatty acid. Evidence exists that ALA supplementation can also have a protective effect on the development on cardiovascular disease, but may exert its cardio protective effects through different routes. The benefit may (partly) be due to blood pressure lowering. However, evidence for beneficial effects of ALA on blood pressure is conflicting. Therefore, we propose to investigate the effect of flaxseed oil, high in ALA, using a study powered on 24-hour blood pressure, in a population with high normal blood pressure and mild hypertension. Objective: To study the effects of flaxseed oil, rich in ALA on 24h-ambulatory mean arterial pressure (MAP) in men and women with high-normal blood pressure and mild hypertension compared to high oleic sunflower oil, poor in ALA. Study design: Using a double blind randomized, placebo-controlled parallel design, subjects will receive at random daily 10 g of flaxseed oil or a high-oleic acid sunflower oil (HOSF) as control for twelve weeks, with a run-in period of 14 days in advance. Study population: 72 men and women, aged 40-70 years, with untreated high-normal blood pressure and stage I hypertension and a body mass index between 25 and 35 kg/m2 will participate in the run-in and intervention period. It is estimated that 144 subject have to be screened to find 72 subjects that will enter the run-in period. Intervention: During the run-in period, subjects will receive daily 10 g of palm super olein oil. During the intervention period subjects receive either 10 g of HOSF or flaxseed oil. All oils are provided in bottles of 5 g, one will be consumed at breakfast or lunch and one at dinner. Main study parameters/endpoints: The main study parameter is the change in 24h-ambulatory mean arterial pressure (MAP)
