Hepatic lipase (HL) is a key enzyme catalyzing the hydrolysis of triglycerides (TG) and phospholipids (PLs) in several lipoproteins. It is generally recognized that HL is involved in the remodeling of remnant, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and the production of small, dense low-density lipoproteins (sd-LDLs).On the other hand, it is unclear whether HL accelerates...

accumulating evidence suggest that in patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. to evaluate the association of oxidized low- density lipoprotein (ox-ldl) with the development of diabetic nephropathy, plasma level of ox-ldl were measured in 70 diabetic patients with macro and 63...

liver secretes a large range of very low density lipoprotein (vldl) particles of different sizes and svedberg flotation rates (sf). in plasma vldl is converted to low density lipoprotein (ldl)which in turn plays an important role in the development of atherosclerotic diseases; however,triglyceride (tg) rich vldl1 has been shown to be more deleterious than cholesteryl ester (ce) rich vldl2. ther...

Background and Aims: Small dense  low-density lipoproteins (sd-LDL) particles are smaller and heavier than typical LDL ones. They can penetrate into the endothelium of coronary arteries more easily because of their small size. Diabetes mellitus is accompanied by dyslipidemia such as increasing concentration of plasma very low density lipoprotein and sd-LDL. Peroxisome proliferator activated rec...

Human plasma contains a multivalent, Kunitz-type proteinase inhibitor termed tissue factor pathway inhibitor (TFPI), which specifically inhibits the action of the factor VII(a)-tissue factor complex in coagulation. In the present study, we examined the distribution and anticoagulant activity of TFPI among plasma lipoprotein subspecies separated by isopycnic density gradient ultracentrifugation;...

Dyslipidemia is a heterogeneous metabolic condition; high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very-low-density lipoprotein represent families of lipoprotein particles that differ in size and composition and vary in atherogenicity. Lipoprotein subclasses containing apolipoprotein B promote atherosclerosis, of which the most atherogenic appear to be the small, dense LDL ...
