HDL3 Exerts a More Powerful Antiperoxidative and Protective Effect against Peroxidative Modification of LDL than HDL2 Does.

Both HDL3 and HDL2 exert a powerful anti-oxidative and protective effect against acceleration of oxidative modification of LDL by ascorbic acid.

The objective of the present study was to establish whether high-density lipoprotein 3 (HDL3) or high-density lipoprotein 2 (HDL2) might show an anti-oxidative effect on the acceleration of the oxidative modification of low-density lipoprotein (LDL) by ascorbic acid from measurement of the agarose gel electrophoretic mobility of LDL. LDL was incubated without adding transitional-metal ions for ...

Associations between small dense LDL, HDL subfractions (HDL2, HDL3) and risk of atherosclerosis in Japanese-Americans.

AIM Small dense low-density lipoprotein (sdLDL) has been suggested to be more atherogenic than large buoyant LDL. High-density lipoprotein (HDL) consists of two major subfractions (HDL2, HDL3), and just as controversy remains regarding which of the two is the more powerful negative risk factor for atherosclerosis, associations between sdLDL and these HDL subfractions are unclear. METHODS We m...

isolation of hdl2 and hdl3 assessment of concentration of cholesterol

the major lipoprotein classes are heterogenous. human serum high-density-lipoproteins (hdl) are separated into two major subfractions (hdl2, d=1.063-1.125 g/ml, hdl3, d=1.125-1.210 g/ml) by a simple double precipitation method. there was a strong inverse relation between hdl-cholesterol (hdl-c) and subfractions hdl2-c and hdl3-c with atherosclerosis. this study demonstrated that hdl-c (p<0.001)...

Adaptation as a more powerful tool than decomposition and integration

Recently a new way of building control systems, known as behavior based robotics, has been proposed to overcome the difficulties of the traditional AI approach to robotics. Most of the work done in behavior-based robotics involves a decomposition process (in which the behavior required is broken down into simpler sub-components) and in an integration approach (in which the modules designed to p...
