The OLR1 gene encodes the oxidized low-density lipoprotein receptor (LOX-1), which is responsible for the cellular uptake of oxidized LDL (Ox-LDL), foam cell formation in atheroma plaques and atherosclerotic plaque rupture. Alternative splicing (AS) of OLR1 exon 5 generates two protein isoforms with antagonistic functions in Ox-LDL uptake. Previous work identified six single nucleotide polymorp...

OBJECTIVE Chronic infection has long been postulated as a stimulus for atherogenesis. Pseudomonas aeruginosa infection has been associated with increased atherosclerosis in rats, and these bacteria produce a quorum-sensing molecule 3-oxo-dodecynoyl-homoserine lactone (3OC12-HSL) that is critical for colonization and virulence. Paraoxonase 2 (PON2) hydrolyzes 3OC12-HSL and also protects against ...

OBJECTIVE Oxidized LDL cholesterol (ox-LDL-C) is considered to be a key factor of initiating and accelerating atherosclerosis (AS). The purpose of this study is to elucidate the sensitivity and specificity of ox-LDL and oxidation ratio of LDL in the diagnosis of coronary artery disease (CAD). For the first time, we investigated the ratio of ox-LDL to ALB(ox-LDL/ALB). METHODS AND RESULTS Blood...

OBJECTIVE Wnt5a is a secreted glycoprotein highly present in atherosclerotic lesions. Uptake of oxidized-low density lipoprotein (ox-LDL) by monocytes/macrophages plays a critical role in atherosclerosis. The objective of this study was to determine if Wnt5a mRNA expression correlates with the severity of atherosclerotic lesions, and if, ox-LDL can induce Wnt5a mRNA in macrophages. METHODS Wn...

The mechanism(s) of inhibition of endothelium-dependent relaxation (EDR) by oxidized low-density lipoprotein (Ox-LDL) was examined in isolated porcine coronary arteries and rabbit aortas. Incubation with Ox-LDL but not native LDL caused the inhibition of thrombin- or acetylcholine-induced EDR, whereas A23187-induced EDR was preserved after incubation with Ox-LDL. Lysophosphatidylcholine (lysoPC...

BACKGROUND Oxidized low-density lipoprotein (oxLDL) leads to atherosclerosis and cardiovascular disease, the most frequent causes of death worldwide. After menopause, lipid and lipoprotein metabolism changes and women are at greater risk of cardiovascular disease compared to fertile women. The aim of this study was to determine the prevalence of serum oxLDL in postmenopausal women and to identi...

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...

abstract probiotic products highly affect the health of consumers by reducing the risk of heart attacks and improving of desirable microflora in intestinal tract. in this study the effect of yogurt (500g/d for 3 wk) enriched with either bifidobacterium bifidum or lactobacillus acidophilus on the level of cholesterol, low density lipoprotein (ldl) and high density lipoprotein (hdl) of serum and ...

background: the association between the lipid profiles level and the incidence and severity of coronary heart disease (chd) is very pronounced in epidemiological studies, and an inverse relation between physical fitness and the incidence of coronary heart disease has been observed in many studies. the aim of this study was to investigate the impact of a soccer match on lipid parameters of profe...

introduction: abnormal lipid profile causes maternal mortality and impairs fetal development. this study investigated the effect of ramadan fasting on plasma lipid profile in pregnant women. material and methods: this self-control, cohort study was performed in healthy volunteer fasted pregnant women. serum cholesterol, triglyceride (tg), low density lipoprotein (ldl), high density lipoprotein ...
