High-density lipoprotein (HDL) plays a major role in vasodilation and in the reduction of low-density lipoprotein (LDL) oxidation, inflammation, apoptosis, thrombosis, and infection; however, HDL is now less functional in these roles under certain conditions. This paper focuses on HDL, its anti-inflammation behavior, and the mechanisms by which HDL interacts with components of the innate and ad...

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-...

CETP is a hydrophobic glycoprotein secreted by the liver and is predominantly associated with apo A-I containing lipoproteins in the plasm. CETP plays important roles in modulating vascular lipoproteins. It facilitates the redistribution of cholesterol esters, phospholipids, and triglycerides between plasma lipoproteins. As a consequence of CETP-mediated transfer of cholesterol esters from HDL(...

Overview: Lipoproteins are spherical particles that carry lipids, particularly cholesterol and triglyceride, in the plasma. There is a well-established association between dyslipidemias, or disorders of lipoprotein metabolism, and coronary heart disease (CHD): elevated levels of blood cholesterol, especially low-density lipoprotein cholesterol (LDL-C), and low levels of high-density lipoprotein...

It is believed that the cyclic variations in sex hormones across the menstrual cycle may have effects on the lipid profile and hence on cardiovascular health. Thus, the purpose of study was to find out the serum levels of lipids and lipoprotein ratios in different phases of menstrual cycle in eumenorrheic women. One hundred and twenty young healthy female subjects of reproductive age group (17-...

The major lipoprotein density classes (chylomicrons-VLDL, LDL, HDL(2) and HDL(3)) were isolated from human plasma in a two-step ultracentrifugal procedure using the Ti-14 zonal rotor. The isolation of the two major high density lipoprotein subclasses (HDL(2) and HDL(3)) was achieved in a 24-hr run using a nonlinear NaBr gradient in the density range of 1.00-1.40. The lipoproteins with a density...

Lipoprotein cholesterol and triglyceride concentrations were compared in diabetic and nondiabetic Pima Indians, a homogeneous population with a high occurrence of noninsulin-dependent diabetes mellitus. Data were available on 690 subjects with diabetes or impaired glucose tolerance. Total and very low density lipoprotein (VLDL) triglycerides were approximately 150% of the nondiabetic values, bu...

CONTEXT Systemic inflammatory diseases are associated with proatherogenic lipoprotein profile, but there is a lack of information regarding overall distributions of lipoprotein subclasses in sarcoidosis. OBJECTIVE To investigate whether patients with sarcoidosis have altered distributions of plasma low-density lipoprotein (LDL) and high-density lipoprotein (HDL) particles. DESIGN Seventy-se...
