Apolipoproteins are associated with survival among patients on hemodialysis (HD), but these associations might be influenced by dysfunctional (oxidized) high-density lipoprotein (HDL). We assessed associations among apolipoproteins and oxidized HDL, mortality and cardiovascular disease (CVD) events in patients on HD. This prospective observational study examined 412 patients on prevalent HD. Bl...

Deficiency of the cholesteryl ester transfer protein (CETP) in humans is characterized by markedly elevated plasma concentrations ofHDL cholesterol and apoA-I. To assess the metabolism ofHDL apolipoproteins in CETP deficiency, in vivo apolipoprotein kinetic studies were performed using endogenous and exogenous labeling techniques in two unrelated homozygotes with CETP deficiency, one heterozygo...

CONTEXT Associations of major lipids and apolipoproteins with the risk of vascular disease have not been reliably quantified. OBJECTIVE To assess major lipids and apolipoproteins in vascular risk. DESIGN, SETTING, AND PARTICIPANTS Individual records were supplied on 302,430 people without initial vascular disease from 68 long-term prospective studies, mostly in Europe and North America. Dur...

The major function of the lipoproteins is to provide the organism with a transport system for triacylglycerol and cholesterol. This system appears to be both highly effective and dynamic in normal subjects. While about 150 g of fat per day are fully absorbed from the gut, the plasma triglyceride pool in the blood is approximately 3 g in the fasting state and does not exceed 12 g in the postabso...

Synthesis and secretion of apolipoproteins in pig small intestine was studied by pulse-chase labeling of jejunal segments, kept in organ culture. Apo A-1 and apo B-48 were the two major proteins released, constituting 25 and 10%, respectively, of the total amount of labeled protein in the mucosal-side medium where they appeared with a t1/2 of 50-60 min. Using tissue from fasting animals, > 85% ...

Addition of sucrose (413-825 mmol/L) to human serum allows plasma lipoproteins to be lyophilized without denaturation. A control serum so prepared is especially suited for use in monitoring determinations of apolipoproteins and quantitative lipoprotein electrophoresis. It is clear upon reconstitution; hence, the described procedure may also be useful for preparation of control sera for general ...

objectives: this study was performed to investigate the effect of ω-3 fatty acids on lipid profiles, lipoprotein (a), apolipoprotein a-1 and apolipoprotein b, fasting glucose and insulin, and insulin resistance in a group of iranian elderly subjects. methods & materials: in this clinical trial, 124 elderly residents of the kahrizakcharity foundation, aged 65 and older were divided into two inte...

We describe the resolution of the plasma apolipoproteins with molecular weights from 8,800 to greater than 550,000, using a 3.5% sodium dodecyl sulfate-glycerol polyacrylamide slab gel system. The simplicity of this system and the resolution of proteins over a broad range of molecular weights will make it particularly useful in investigations of apolipoprotein composition of plasma lipoproteins.
