HDL metabolism and atherosclerosis were studied in apo E knockout (KO) mice overexpressing human apo AI, a des- (190-243)-apo AI carboxyl-terminal deletion mutant of human apo AI or an apo AI-(1-189)-apo AII-(12-77) chimera in which the carboxyl-terminal domain of apo AI was substituted with the pair of helices of apo AII. HDL cholesterol levels ranked: apo AI/apo E KO approximately apo AI-(1-1...

We have reported previously on two truncations of apolipoprotein B (apo B-40 and apo B-89) in a kindred with hypobetalipoproteinemia. Premature stop codons were found to be responsible for both apo B-40 and apo B-89, but the physiologic mechanisms accounting for the reduced plasma concentrations of these proteins have not been determined in vivo. This study investigates the metabolism of apo B-...

lipoprotein (a) [lp (a) is formed by assembly of ldl-particles and the carbohydrate rich protein, apolipoprotein (a) [apo (a)]. elevated plasma lp (a) levels are an independent predictor of the development of premature coronary artery disease (cad), but is not clear whether the apo (a) isoform plays on additional and independent role or not. to investigate the possible effect of apo (a) isoform...

BACKGROUND VLDL and chylomicrons may interfere with measurements of apolipoprotein B (apo B) on LDL particles. Ultracentrifugation of samples enriched in chylomicrons and VLDL and subsequent measurement of apo B in the infranate fraction [density (d) = 1.006] removes this interference. This apo B fraction is called "LDL-apo B." METHODS We retrospectively analyzed 64 895 measurements of trigly...

Apo A-IMilano is a mutant form of apo A-I in which cysteine is substituted for arginine at amino acid 173. Subjects with apo A-IMilano are characterized by having low levels of plasma HDL cholesterol and apo A-I. To determine the kinetic etiology of the decreased plasma levels of the apo A-I in these individuals, normal and mutant apo A-I were isolated, radiolabeled with either 125I or 131I, an...

Bu çalışma, %4 kadife çiçeği (Tagetes erecta), 0 ve 100 mg/kg sentetik apo-ester içeren diyetlerle 60 gün beslenen sarı prenses balığının (Labidochromis caeruleus) deri rengi yetiştiricilik parametreleri üzerindeki etkilerini belirlemek amacıyla gerçekleştirilmiştir. Deri rengi, kolorimetrik yöntemle bir yansıtma spektroskopisi kullanılarak ölçülmüştür. Kadife apo-esterin balıkların renk (L*,a*...
