The purpose of this study is to evaluate the multiple-dose pharmacokinetic characteristics and pharmacologic activity of gemcabene.

Objective: To investigate the effect of 5 weeks dapagliflozin 10 mg once daily treatment on glucose and lipid fluxes in patients with type 2 diabetes. Study design: Single center single arm (mechanistic) intervention trial. Study Population: Male or postmenopausal female patients with type 2 diabetes BMI > 25 kg/m2and more than 12 weeks a stable dose of metformin treatment > 1500mg, HbA1C ≥6.5% - <8.5%, Fasting Plasma Glucose (FPG) <13.2 mmol/l, LDL cholesterol >2.5 mmol/l, willing to switch to rosuvastatin 10mg once daily for 4 weeks, and then receive 10 mg dapagliflozin once daily orally, for 5 weeks. Treatment: After a statin washout fase of 4 weeks, baseline cholesterol synthesis will be measured (2H3 Leucine, 2H2O deuterated water). Then, treatment with rosuvastatin 10mg for 4 weeks will be initiated after which, patients will undergo glucose (2H2enriched glucose) and lipid flux (2H3 Leucine, 2H2O deuterated water and oral 1,2,3,4-13C16 - palmitate enrichment measurements) followed by 5 weeks treatment with dapagliflozin 10mg once daily. In the final week glucose/lipid flux measurements will be repeated. Sample Size: 12 DM2 subjects. Outcome measures: The primary endpoint is effect of 5 weeks Sodium-Glucose Linked co-transporter (SGLT) 2 inhibition on LDL cholesterol synthesis in patients with DM2. Secondary endpoints are effect of SGLT2 inhibition on triglyceride and cholesterol fluxes as well as (hepatic and peripheral) insulin sensitivity and energy expenditure. Finally, effect of SGLT2 inhibition on dietary intake, liver fat content (MRI liver) and fecal microbiome will be studied at these timepoints.

The objective of this research project is to investigate the ability to affect cardiovascular disease (CVD) risk factors through a novel, easily implemented functional food-based approach. The goal of the proposed project is to evaluate the effect of a range of proprietary products specifically formulated to deliver convenient pre-packaged condition-specific foods to positively impact blood cholesterol levels in statin intolerant and/or statin unwilling participants. The specific aim of this project is to evaluate the changes in serum low-density lipoprotein (LDL)-cholesterol, triglyceride (TG) glucose, insulin and high-sensitivity C-reactive protein (hsCRP) concentrations over a 4 week regimen using healthy tasty foods which are self-selected by a statin intolerant patient group.

Background: Circulating osteoprogenitors and RANKL expression in immune cells have been implicated in the pathogenesis of osteoporosis and vascular calcification. The role played by statin therapy in the bone-vascular axis is unknown. Methods: Twenty naïve post-menopausal osteoporotic hypercholesterolemic women will be treated with Atorvastatin 40 mg/day for three months. Blood samples will be collected at baseline and at the end of the treatment. Gene expression analysis will be performed to assess modification in OPG/RANK/RANKL expression in isolated T-cells and monocytes. A flow cytometry analysis will be used to study changes in the levels of circulating osteoprogenitor cells.

The study was designed to answer the primary question: the consumption of one apple three times daily between meals reduces serum levels of cholesterol above 240 mg/dL in overweight women? The second and important hypothesis was designed for evaluate the reduction in body weight by intakes of fruits. Therefore, the increased consumption of apples could displace the consumption of other foods and promoting satiety and input significant reduction in body weight compared to other fruit (Pear) of similar nutritional composition or food (cookies) made from oats with fiber and total calories similar to those observed in these fruits. To demonstrate the effectiveness of these supplements we used a clinical trial with three arms (apple, pear and oatmeal cookies).

The purpose of this study is to investigate the cholesterol lowering effect of a drinkable low fat fermented milk enriched with plant sterol after 3 and 6 weeks of daily consumption in midly hypercholesterolemic people not treated by statins.

Diets rich in fruit and vegetables reduce the risk of strokes and heart attacks, however the exact cause of this beneficial effect is uncertain. Evidence suggests that certain vegetables, including beetroot and the green leafy vegetables, possess high inorganic nitrate concentrations. The investigators recent evidence suggests that inorganic nitrate provides a source of gas called nitric oxide in the body that exerts a number of beneficial effects upon the heart and blood vessels . The investigators have previously shown that beetroot juice ingestion improves blood vessel (vascular endothelial) and platelet function in healthy volunteers. Studies by the investigators show that these effects are due to conversion of nitrate to nitrite by symbiotic (helpful) bacteria (located on the tongue) and subsequent conversion of nitrite to nitric oxide in blood vessels. The investigators now wish to explore whether dietary nitrate, via its beneficial effects on platelets and blood vessels, might improve indices of atherosclerotic disease progression in high risk individuals (hypercholesterolemics). Recruits will have high cholesterol and no known atherosclerosis and will not yet be on any anti-cholesterol medications. Volunteers will consume a daily dose of beetroot juice or placebo nitrate-free juice for six weeks. Vascular function will be assessed using non-invasive techniques at the beginning and at the end of the study using ultrasound measurement of flow mediated dilatation (FMD) of the brachial artery in the arm and pulse wave analysis (PWA) and pulse wave velocity (PWV) to measure arterial compliance. To assess impact on platelet function, blood samples will also be taken at the start and at the end of the study.

The objective of this study is to investigate the effect of consumption of a low-fat, no added sugar, dairy fermented product enriched with plant sterols and policosanols at two doses, on LDL-cholesterol concentration in hypercholesterolaemic adults after 3 weeks of product consumption versus active control product.

The main aim of the study is to investigate, in humans, the effect of plant sterols on vascular function by measuring flow-mediated dilation (FMD). This study also aims to study the effect of plant sterols on pulse wave velocity (PWV), aortic augmentation index (Aix), central blood pressure (CBP), office blood pressure (BP), blood lipids and plasma plant sterol concentration. At last, the effects of plant sterols on z-scores of circulating biomarkers of endothelial dysfunction and low-grade inflammation will be assessed. For all study outcomes, effect sizes and 95% confidence intervals will be estimated. Hypothesis: Based on available evidence, it is hypothesized that plant sterols modestly increase FMD.

Primary Objective: To assess the relative bioavailability of a single subcutaneous dose of alirocumab SAR236553 (REGN727) administered at 3 different injection sites in healthy subjects. Secondary Objectives: To assess the pharmacodynamic effect of a single subcutaneous dose of alirocumab SAR236553 (REGN727) on serum low-density lipoprotein cholesterol and other lipids and apolipoproteins. To assess the safety of a single subcutaneous dose of alirocumab SAR236553 (REGN727). To assess the immunogenicity of a single subcutaneous dose of alirocumab SAR236553 (REGN727).
