background: it has been established that hyperlipidemia increases the  incidence and mortality associated with coronary heart disease. in this study, the effects of dill (anethum graveolens) were evaluated on lipid profile of hypercholesterolemic patients. materials and methods: in this clinical study, 91 hyperlipidemic patients were randomly designated into two groups. one group received gemfi...

Phospholipid transfer protein gene knock-out (Pltp KO) mice have defective transfer of very low density lipoprotein (VLDL) phospholipids into high density lipoprotein (HDL) and markedly decreased HDL levels (Jiang et al. 1999. J. Clin. Invest. 103: 907-914). These animals also accumulated VLDL- and LDL-sized lipoproteins on a high saturated fat diet. The goals of this study were to further char...

Changes in lipid fractions were evaluated in young guinea pigs when infected with 1 ml of 7 day old live cultures of leptospira interrogans serovars australis, canicola and icterohaemorrhagiae. Statistically significant elevation in triglycerides, very low density lipoprotein and phospholipid and a significant reduction in high density lipoprotein (HDL) in all the groups was observed. Cholester...

High density lipoproteins (HDL) have been reported to inhibit oxidation of low density lipoproteins (LDL) based in part on observations that oxidative changes occur more slowly in LDL-HDL mixtures than in LDL alone. In the current studies, we developed an approach to discern particle-specific oxidation kinetics within mixed particle systems using the oxidation-labile fluorescent probe parinaric...

T he importance of lipid, lipoprotein, and apolipoprotein risk factors in the prediction, prevention, and regression of atherosclerosis is now well established. The role of elevated low density lipoprotein cholestexol (LDL C) in the development of coronary heart disease (CHD) is supported by evidence from numerous epidemiologic studies, clinical trials, and genetic studies.1-3 High density lipo...

When cultured human fibroblasts were incubated with medium of varying composition, the activity of the low density lipoprotein (LDL) receptor was strongly correlated with the amount of cholesterol that egressed from the cell. Particles isolated from lipoprotein-deficient serum (d > 1.25) by anti-apoprotein (apo) A-I affinity chromatography were as effective as the d > 1.25 serum in activating t...

Background: Serum lipids abnormalities have been observed in various forms of cancers including acute leukemia. Investigators report decreased total cholesterol and HDL, and elevated triglyceride in leukemic patients. Limited studies had been performed to discover the correlation between abnormal lipids profile and disease activity in leukemic patients in Iran. This study was done to evaluate t...

The dual-precipitation method for measurement of cholesterol in high-density lipoprotein subfractions HDL2 and HDL3 (Warnick et al., Clin Chem 1982;28:1574) was compared with quantification of cholesterol in HDL2 and HDL3 by zonal ultracentrifugation (Patsch et al., J Lipid Res 1974;15:356-66). For 39 plasma specimens differing widely in their HDL subfraction cholesterol concentration, the coef...

The release of secretory phospholipase A2 (SPLA,) into the mammalian circulation may contribute to the development of hemorrhagic and inflammatory diseases. sPLA, has previously been shown t o alter the behavior of platelets, leukocytes, and endothelial cells, although the molecular basis for these cellular effects has not been established. Our studies indicate that the inhibition of platelet a...
