Hijamah or cupping therapy has a therapeutic effect on cholesterol. However, there is still lack of studies that investigate the potential in managing apolipoprotein B as proatherogenic agent and A-1 an anti-proatherogenic agent. This study aims to explore lipid profiles apolipoproteins hypercholesterolemic patients. A pre-post experimental design without controls were used. Consecutive samplin...

Lipoprotein retention in the vascular extracellular matrix (ECM) plays a critical role in atherogenesis. Previous studies demonstrated the presence of apo A-I and E in atherosclerotic lesions, suggesting that HDL may be trapped by the artery wall. We sought to determine mechanisms by which HDL could be bound and retained by the arterial wall, and whether apo E was a principal determinant of thi...

The effects of lipolysis of human plasma very low density lipoprotein (VLDL) on the structure and composition of high density lipoproteins (HDL) have been investigated. Lipolysis was performed in a controlled system in vitro containing VLDL (d less than 1.006 g/ml) and HDL3 (d = 1.125-1.210 g/ml) from human plasma and lipoprotein lipase (EC 3.1.1.34) purified from bovine milk. Lipolysis of VLDL...

Scavenger receptor class B type I (SR-BI) mediates the selective uptake of HDL cholesteryl esters (CEs) by the liver. LPL promotes this selective lipid uptake independent of lipolysis. In this study, the role of SR-BI in the mechanism of this LPL-mediated increase in selective CE uptake was explored. Baby hamster kidney (BHK) cells were transfected with the SR-BI cDNA, and significant SR-BI exp...

ApoE synthesis and secretion, as a function of cellular cholesterol content and cholesterol efflux, was studied in thioglycolate-elicited mouse peritoneal macrophages. As expected, loading elicited macrophages with cholesterol induced a 5-fold increase in apoE secretion and a 2.5-fold increase in cellular apoE content over a 5-h period. Treatment of cholesterol-loaded cells with HDL3 further in...

Ultracentrifugally isolated high density lipoprotein (HDL) particles of d greater than 1.125 g/ml promote net transport of cholesterol from cultured cells. Consequently, when cultured human fibroblasts and arterial smooth muscle cells were incubated with HDL3 (d = 1.125-1.21 g/ml) and "very high" density lipoprotein (VHDL, d = 1.21-1.25 g/ml), low density lipoprotein (LDL) receptor activity was...

Intake of a high dosage of baicalin has previously been shown to attenuate hyperlipidemia induced by a high-fat diet. Baicalin functions as an activator of peroxisome proliferator-activated receptor-γ (PPAR-γ), which is the key regulator of reverse cholesterol transport (RCT). The present study aimed to test the hypothesis that baicalin could promote cholesterol efflux in macrophages through ac...
