Giant HeLa cells, having a spread diameter of about 200 micrometers, were briefly surface-labeled at 0 degree C with 125I-labeled transferrin, low density lipoprotein, anti-HeLa cell antibody, or concanavalin A. The cells were washed at 0 degree C, fixed, and autoradiographed. The distribution of grains when either anti-HeLa cell antibodies or concanavalin A was used was roughly as expected: th...

low density lipoprotein (ldl) subclass pattern b is characterized by predominance of small dense ldl. subjects with pattern b tend to have higher triglyceride (tg) and lower levels of high density lipoprotein cholesterol (hdl-c). small dense ldl is associated with increased risk of coronary disease. in this study, effect of non-insulin dependent diabetes mellitus (niddm) on ldl size, plasma tg ...

Treatment of postmenopausal women with low doses of estradiol-17 beta (1 mg/d) and dl-norgestrel (0.075 [corrected] mg/d) significantly reduced fasting serum levels of low density lipoprotein (LDL) cholesterol and lowered very low density lipoprotein (VLDL) triglycerides in four of five subjects. To explain these results, the kinetics of VLDL and LDL apolipoprotein (apo) B turnover were studied...

The low density lipoprotein (LDL) receptor mediates the cellular uptake of plasma lipoproteins that are derived from very low density lipoproteins (VLDL). Most of the functional LDL receptors in the body are located in the liver. Here, we describe a radionuclide scintiscanning technique that permits the measurement of LDL receptors in the livers of intact rabbits. 123I-labeled VLDL were adminis...

background: dyslipidemia is considered an independent risk factor for coronary heart disease (chd). in the present study, we examined lipid profiles and paraoxonase 1 (pon1) activity and atherogenic indexes status and the relationship of pon1 activity by high-density lipoprotein (hdl) and atherogenic indexes in chd patients and healthy people. methods: the aim of the study was to compare pon1, ...
