BACKGROUND HDL cholesterol (HDL-C) is an established marker of cardiovascular risk with significant genetic determination. However, HDL particles are not homogenous, and refined HDL phenotyping may improve insight into regulation of HDL metabolism. We therefore assessed HDL particles by NMR spectroscopy and conducted a large-scale candidate gene association analysis. METHODOLOGY/PRINCIPAL FIN...

Clinical studies indicate that levels of apolipoprotein A-I (apo A-I), the major protein moiety of the high density lipoprotein (HDL) particle, may provide more information concerning the risk of future cardiovascular disease than do levels of HDL cholesterol (HDL-C). Therefore, the relationship of HDL-C to apo A-I levels was examined in a biracial sample of 2849 5- to 17-year-olds. The mean HD...

Clinical studies Indicate that levels of apolipoprotein A-l (apo A-l), the major protein moiety of the high density lipoprotein (HDL) particle, may provide more Information concerning the risk of future cardiovascular disease than do levels of HDL cholesterol (HDL-C). Therefore, the relationship of HDL-C to apo A-l levels was examined In a blraclal sample of 2849 5to 17-year-olds. The mean HDL-...

Negative relationship between plasma high-density lipoprotein (HDL) levels and risk of cardiovascular disease (CVD) is a firmly established medical fact, but attempts to reproduce protective properties of HDL by pharmacologically elevating HDL levels were mostly unsuccessful. This conundrum presents a fundamental question: were the approaches used to raise HDL flawed or the protective effects o...

Mutations in the CETP gene resulting in defective CETP activity have been shown to cause remarkable elevations of plasma HDL-C levels, with the accumulation in plasma of large, buoyant HDL particles enriched in apolipoprotein E. Genetic CETP deficiency thus represents a unique tool to evaluate how structural alterations of HDL impact on HDL atheroprotective functions. Aim of the present study w...

The concentration dependence and tissue distribution of high density lipoprotein (HDL) cholesteryl ester and apolipoprotein (apo) transport were determined in apoA-I knockout mice (apoA-I-/-) that lack normal HDL in plasma. Rates of HDL cholesteryl ester clearance were highly sensitive to plasma HDL cholesteryl ester concentrations with clearance rates falling by 80% in the liver and by 95% in ...

Indonesia dianugerahi keanekaragaman hayati yang melimpah, salah satunya tanaman obat. Andong merah merupakan satu obat banyak digunakan masyarakat Indonesia. Penelitian eksperimental laboratorium ini bertujuan untuk menentukan aktivitas ekstrak daun andong terhapap kadar kolesterol, Low Density Lipoprotein (LDL), dan High (HDL) pada mencit hiperkolesterol. menggunakan 4 kelompok hewan uji, yai...

In a prospective epidemiologic study in company employees in Westfalia aimed at improving early diagnosis of coronary heart disease in 3069 men and 1387 women, concentrations of HDL-apolipoprotein A-I and HDL-cholesterol were measured and the results were correlated with several risk factors of coronary heart disease. A negative correlation between hypertriglyceridaemia and HDL-cholesterol (r =...

High-density lipoprotein (HDL) is highly heterogeneous in its size and composition. Till now, the link of HDL subfractions to coronary risk is less clear. We aimed to investigate the associations of HDL subfractions with traditional risk factors (RFs), coronary severity, and outcomes in a cohort of nontreated patients with stable coronary artery disease (CAD). We prospectively enrolled 591 elig...

BACKGROUND High-density lipoproteins (HDL) are structurally and metabolically heterogeneous and subclasses with differential effects on coronary heart disease (CHD) might exist. Apolipoprotein (apo) C-III, a small proinflammatory protein that resides on the surface of lipoproteins, enhances the atherogenicity of VLDL and LDL particles, but little is known about the role apoC-III on HDL. We inve...
