We previously showed that injection of recombinant human group IIA secreted phospholipase A2 (hGIIA sPLA2) to Plasmodium chabaudi-infected mice lowers parasitaemia by 20%. Here, we show transgenic (TG) overexpressing hGIIA sPLA2 have a peak about 30% lower than WT littermates. During infection, levels circulating sPLA2, enzymatic activity and plasma lipid peroxidation were maximal at day-14, th...

Background and Aims: Type and saturation of fatty acids can have an important impact on the level of triglyceride, cholesterol, very low and low-density lipoproteins in the blood and thus affect the development of atherosclerosis. Saturated fatty acids have an additive effect on blood cholesterol while for unsaturated fatty acids, a lowering effect has been reported. Fatty acids can have differ...

Abstract Background The second-generation antipsychotics (SGAs) are a group of antipsychotic drugs, used to treat psychiatric conditions. SGAs have been shown precipitate rapid weight gain and dyslipidemia, as well promote insulin resistance, leading the emergence type 2 diabetes metabolic syndrome. Prescriptions in children increased 6- 10-fold during last decade. This research work designed f...

In subjects with insulin-dependent diabetes mellitus, microalbuminuria has been associated with increased triglyceride and lipoprotein (a) (Lp[a]) concentrations and increased blood pressure. However, few studies have examined whether this association is present in subjects with non-insulin-dependent diabetes mellitus (NIDDM). We measured lipids, lipoproteins, Lp(a), blood pressure, and albumin...

High blood pressure and lipoprotein abnormalities were identified by many cohort studies as the major risk factors for cardiovascular disease. Laboratory experiments apparently confirmed their role in the causation of atherosclerosis, but a proof of concept requires the corroboration by clinical trials in human beings. The size of benefit in clinical trials regarding the control of high blood p...

background: this study was done to test the notion that opium can reduce serum lipids and decrease the risk of ischemic heart disease (ihd) in opium addicts; we made a comparison between the lipid profiles of opium addicts and non-addicts.   methods: in this study, we compared 100 male opium addicts (according to the icd-10 criteria) who had referred to addiction treatment centers with 75 healt...

Bacterial endotoxin (lipopolysaccharide [LPS]) is known to interact with numerous components of blood, including erythrocytes, mononuclear cells, platelets, neutrophils, lipoproteins, and plasma proteins. The relative affinities of LPS for these elements, and the distribution of LPS between them, are unknown. Cross-linked stroma-free hemoglobin (SFH), a potential substitute for erythrocyte tran...

The triacylglycerol content of chylomicrons and VLDL (very-low-density lipoprotein) compete for the same lipolytic pathway in the capillary beds. Although chylomicron triacylglycerols appear to be the favoured substrate for lipoprotein lipase, VLDL particles compete in numbers. Methods to quantify the specific triacylglycerol removal from VLDL and chylomicrons may involve endogenous labelling o...

This memoir provides a history of the triglyceride-rich lipoproteins of blood plasma over the last half-century. As precursors of low-density lipoproteins and in their own right, triglyceride-rich lipoproteins are essential to the formation of atherosclerotic plaques and to consequent ischemic vascular disease. The author recounts research at the National Heart Institute during 1953 to 1956 and...

Polyacrylate (PAA) adsorbents selectively bind low density lipoproteins (LDL) from human plasma and blood, whereas very low density lipoproteins (VLDL) are only minimally adsorbed. The adsorption of cholesterol-rich lipoproteins to PAA adsorbents is related to the molecular weight (mw) of the polyanion ligand. Ca(++) and Mg(++) inhibit the binding of LDL to PAA adsorbents. The chemical composit...
