Abstract:
Chylomicron remnants labelled biologically with [3H]cholesterol were efficiently taken up by freshly isolated hepatocytes during a 3 h incubation in Krebs bicarbonate medium. Their [3H]cholesteryl ester was hydrolysed (74% net hydrolysis), and 0.1 mM-chloroquine could partially inhibit this hydrolysis, provided that hepatocytes were first preincubated for 2 h 30 min at 37 degrees C. This hydrolysis was also measured in preincubated cells with remnants double-labelled (3H and 14C) on their free cholesterol moiety; [3H]cholesterol arising from [3H]cholesteryl ester hydrolysis was recovered in th

Abstract:
Methimazole-treated hypothyroid rats were injected intravenously with triacylglycerol/cholesteryl oleate/cholesterol/phospholipid emulsions designed to model the composition of chylomicrons. Compared with controls, hypothyroidism decreased the clearance rates of emulsion cholesteryl oleate. Clearance of emulsion triolein was affected much less and could be accounted for by residual triolein in remnants, suggesting that triacylglycerol lipolysis by lipoprotein lipase was unaffected by hypothyroidism but that clearance of remnants from plasma was decreased.

We aimed to investigate the metabolism of chylomicron remnants in the postabsorptive state employing a new stable isotope breath test in centrally obese men without overt hyperlipidaemia. Groups of 12 centrally obese and 12 non-obese men of similar age and with similar plasma cholesterol and triacylglycerol (triglyceride) levels were studied. The catabolism of chylomicron remnants was measured using an intravenous injection of a remnant-like emulsion containing cholesteryl [13C]oleate.

Abstract:
Abstract Background: Triglyceride-rich lipoprotein remnants are atherogenic, and this may be particularly important in visceral obesity. We investigated remnant metabolism in obese men by measuring remnant-like particle-cholesterol (RLP-C), apolipoprotein (apo) B-48, apoC-III, and the clearance of a labeled remnant-like emulsion. Methods: Fasting RLP-C, apoB-48, and apoC-III concentrations were measured in 48 viscerally obese men and 10 lean controls. RLP-C was determined by immunoseparation assay, apoB-48 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and enhanced chemiluminesce

Labelled remnants from butter fat and fish oil were removed more rapidly from the perfusate than remnants derived from olive, corn and palm oil.

Abstract Background: Quantification of triglyceride-rich lipoprotein (TRL) remnants is useful for risk assessment of coronary artery disease and the diagnosis of type III hyperlipoproteinemia.

The dysmetabolic syndrome of insulin resistance and visceral obesity is characterized by elevated plasma concentration of triacylglycerol-rich lipoprotein (TRL) remnants that may be related to increased cardiovascular risk.

Abstract:
Lipids are carried in plasma as microparticles, lipoproteins, composed of a core of hydrophobic lipids and a surface of amphipathic lipids. In addition, the particles carry proteins (i.e. apolipoproteins). The proteins have key functions in the metabolism as receptor ligands, enzymes or activators. Lipoproteins are classified based on density into: chylomicrons, VLDL, IDL, LDL, and HDL. Retention of apoB-containing lipoproteins (LDL, IDL, and VLDL) in the arterial intima is the initiating event in the development of atherosclerosis. Retention is mediated by binding of apoB to structural proteo

High blood cholesterol and high blood triglycerides are causal risk factors for atherosclerotic cardiovascular disease, which remains the leading cause of death in the developed world.

The pressure pulse wave augmentation index and the pulse wave velocity increase.
