very-low-density lipoproteins
1. Human total HDL (high-density lipoprotein), HDL2 and HDL3 were labelled in vitro by incubation with lipoproteindeficient serum (LPDS) which contained either [3H]cholesteryl oleate or [14C]cholesterol under different conditions. The lipoproteins were then subfractionated by heparin-Sepharose column chromatography, and three subfractions (A, B and C) were successively eluted from each preparat...
متن کاملOxidized Low Density Lipoproteins
The direct vasoactive effects of native and oxidatively modified low density lipoproteins as well as their effects on endothelium-dependent relaxations to 5-hydroxytryptamine were studied in isolated rings of pig right coronary artery. Slowly developing contractions were caused by native low density lipoproteins (100 gg protein/ml). The contractions were more pronounced in the absence than in t...
متن کاملA new apoprotein of human plasma very low density lipoproteins.
A new apoprotein has been isolated from delipidated human very low density lipoproteins by Sepharose 6B chromatography in 6 Y guanidine hydrochloride. This water-insoluble protein was noted to be unique to the plasma very low density and chylomicron fractions. This protein was shown to be homogeneous by urea-DEAE-cellulose chromatography, rechromatography in a guanidine-Sepharose system, sodium...
متن کاملDevelopment of an integrated model for analysis of the kinetics of apolipoprotein B in plasma very low density lipoproteins, intermediate density lipoproteins, and low density lipoproteins.
To quantify more precisely the metabolism of apolipoprotein B (apo B) in human beings, an integrated model was developed for the analysis of the isotope kinetics of apo B in very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), and low density lipoproteins (LDL). The experimental basis for model development was a series of 30 triple-isotope studies in which patients rec...
متن کاملAnalytical capillary isotachophoresis of total plasma lipoproteins: a new tool to identify atherogenic low density lipoproteins.
Plasma low density lipoproteins from 20 patients were separated by capillary isotachophoresis (ITP). In each patient the apparent diameter of the predominant LDL peak on whole plasma was also determined by nondenaturing gradient gel electrophoresis. Furthermore the concentration of the more electronegatively charged in vivo oxidized LDL- was accomplished using anion exchange high pressure liqui...
