Orange juice (OJ) is regularly consumed worldwide, but its effects on plasma lipids have rarely been explored. This study hypothesized that consumption of OJ concentrate would improve lipid levels and lipid metabolism, which are important in high-density lipoprotein (HDL) function in normolipidemic (NC) and hypercholesterolemic (HCH) subjects. Fourteen HCH and 31 NC adults consumed 750 mL/day O...

Low plasma levels of total cholesterol (TC) with or without hypertriglyceridemia have been frequently described in a variety of hematologic disorders in which anemia is a prominent feature.2,3 It is well established that β-thalassemia is associated with changes in plasma lipids and lipoproteins. In β-thalassemia major, low cholesterol levels caused by a significant reduction of both low-density...

BACKGROUND The role of lipoprotein disturbances in the development of peripheral vascular disease (PVD) has not been sufficiently clarified. METHODS AND RESULTS The relations among concentrations of intermediate density lipoproteins (IDL), apoprotein (apo) B, apo E, and other lipoproteins were studied in 102 men with PVD and 100 healthy men who formed the control group. Patients with PVD had ...

A cross-sectional study of a random sample of 976 coloureds (mixed race) of the Cape Peninsula, ages 15 to 64 years old, revealed a population with unexpectedly high levels of high density lipoprotein (HDL) cholesterol. The mean level for men was 55.4 +/- 16.1 mg/dl (SD) and for women, 60.8 +/- 16.0 mg/dl. The ratio of HDL cholesterol to total cholesterol expressed as a percentage was 26.3% +/-...

Elevated levels of low-density lipoprotein cholesterol (LDL-C) increase the risk of coronary heart disease (CHD), but pharmacologic therapy to decrease LDL-C significantly reduces the risk of cardiovascular events. Despite the effectiveness of statin therapy, there remains significant residual cardiovascular risk. A low plasma concentration of high-density lipoprotein cholesterol (HDL-C) is ass...

A low level of high-density lipoprotein (HDL) cholesterol is characteristic of insulin resistance and hypertriglyceridemia and likely contributes to the increased risk of cardiovascular disease associated with these conditions. One pathway involves enhanced clearance of lipolytically modified HDL particles, but the underlying mechanisms remain poorly understood. Here, we examine the effect of t...

  Purpose: Ascorbic acid has protective effects against coronary heart disease. These effects are   attributed to its antioxidant properties and its relation to plasma lipids. This study investigated the   effects of supplementing one gram of vitamin C per day on the serum serum lipoproteins of   healthy 18 to 55 years old individuals in Iran.   Materials and Methods: This study was conducted o...

Vitamin D is associated with established cardiovascular risk factors such as low density lipoprotein (LDL) in adults. It is unknown whether these associations are present in early childhood. To determine whether serum 25-hydroxyvitamin D (25(OH)D) is associated with serum non-high density lipoprotein (non-HDL) cholesterol during early childhood we conducted a cross-sectional study of children a...

High-density lipoprotein (HDL3) particles bind to a cell surface receptor, thereby promoting the efflux of cholesterol from extrahepatic nonsteroidogenic cells. This receptor appears to be upregulated by increased cell cholesterol content and also may be responsive to the growth state of cells. Because insulin can be mitogenic, the effect of insulin on HDL-receptor function was tested. HDL-rece...
