BACKGROUND Alirocumab, a monoclonal antibody to proprotein convertase subtilisin/kexin type 9 (PCSK9), lowers plasma low-density lipoprotein (LDL) cholesterol and apolipoprotein B100 (apoB). Although studies in mice and cells have identified increased hepatic LDL receptors as the basis for LDL lowering by PCSK9 inhibitors, there have been no human studies characterizing the effects of PCSK9 inh...

OBJECTIVE The American College of Cardiology and American Heart Association have issued guidelines indicating that the contribution of apolipoprotein B-100 (ApoB) to cardiovascular risk assessment remains uncertain. The present analysis evaluates whether lipoprotein particle measures convey risk of coronary heart disease (CHD) in 4679 Multi-Ethnic Study of Atherosclerosis (MESA) participants. ...

AIM Evaluation of serum lipoprotein profiles including triglyceride (TG)-rich lipoprotein, that is, intermediate-density lipoprotein (IDL), very low-density lipoprotein (VLDL), and chylomicron (CM) remnant is important to manage coronary heart disease (CHD) risk. The purpose of this study was to investigate CHD or cardiovascular disease (CVD) risk scores with cholesterol levels of six fractiona...

INTRODUCTION Premature development of atherosclerosis in systemic lupus erythematosus has been widely reported. Anti-lipoprotein lipase antibody may be one cause contributing to this disorder. OBJECTIVE To assess the extent of coronary risk due to autoimmune antibodies in terms of carotid plaque in lupus patients. PATIENTS AND METHODS We compared 114 documented lupus patients with 111 norma...

We assessed lipid and lipoprotein levels in 100 women taking low-dose COCs and a control group of 100 non-users attending the family planning centre Basra Maternity and Child Hospital, Iraq. Venous blood was collected after 12-14 hours fasting, and serum triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and very ...

Lipoprotein(a) [Lp(a)] represents a class of low density lipoprotein (LDL) particles that have as a protein moiety apolipoprotein B-100-linked covalently to a single molecule of apolipoprotein(a) [apo(a)], a specific multikringle protein of the plasminogen family. Lp(a) is polymorphic in density because of either the density heterogeneity of constitutive LDL, apo(a) size, or both. Authentic LDL...

Small, dense, electronegative low density lipoprotein [LDL(-)] is increased in patients with familial hypercholesterolemia and diabetes, populations at increased risk for coronary artery disease. It is present to a lesser extent in normolipidemic subjects. The mechanistic link between small, dense LDL(-) and atherogenesis is not known. To begin to address this, we studied the composition and dy...

Background: Dyslipidemia is a lipid metabolism disorder that causes changes in plasma lipoprotein function and/or levels of Triglycerides (TG), total cholesterol (TC), Low-Density Lipoprotein (LDL), and High-Density (HDL). Administration Medium Chain Triglyceride (MCT) non-pharmacological therapy effectively improves profiles reduces the risk dyslipidemia. Objectives: This study aimed to conduc...

Density gradient ultracentrifugation (DGUC) and gel electrophoresis are conventionally used to obtain lipoprotein profiles of animals. We recently applied high-performance liquid chromatography with a gel permeation column (GP-HPLC) and an on-line dual enzymatic system to dogs for lipoprotein profile analysis. We compared the GP-HPLC with DGUC as a method to obtain a feline lipoprotein profile....

BACKGROUND: Cholesterol ester transfer protein (CETP) plays a major role in regulating the levels of LDL- and HDL-cholesterol. We previously observed a fish-oil-induced elevation of low-density lipoprotein (LDL)-and very-low-density lipoprotein (VLDL)-cholesterol concentrations and a decrease in high-density lipoprotein (HDL)-cholesterol concentration in F1B hamsters. The molecular mechanism/s ...
