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...

An organocatalyzed one-pot sequential deracemization of aromatic ketones bearing a stereogenic center at the α-position was achieved thanks to an acid-base strategy involving enantioselective protonation reaction as key step. This simple and efficient protocol yields enantioenriched in up 89% ee without need isolate sensitive intermediates such silyl enolates. The role water this process underl...

BACKGROUND Oxidized lipoprotein(a) [ox-Lp(a)] and oxidized low density lipoprotein (ox-LDL) levels have been reported to be useful predictors of cardiovascular events. The study developed a chemiluminescence (CL) imaging immunoassay method for simultaneously detecting serum concentrations of ox-Lp(a) and ox-LDL. METHODS Ox-Lp(a) and ox-LDL levels were measured by CL imaging immunoassay using ...

Objective(s) Oxidized low-density lipoproteins (ox-LDLs) appear to play a significant role in atherogenesis. In fact, circulating ox-LDL concentrations have been recognized as a risk factor for cardiovascular disease (CVD). The main objectives of this study were to assess the effects of antioxidant vitamins on ox-LDL as a biomarker of CVD in male subjects with CVD risk factors. Materials and ...

Background: Sperm cryopreservation is an important tool for breed improvement, nonetheless, spermatozoids of rams are extremely sensitive to cryopreservation. Aims: The present research was to compare a liposome-based (OptiXcell: OX) diluent, a commercial TRIS-egg yolk (Optidyl: OP) and a citrate egg yolk-based (CY) diluent on ovine semen quality through the cr...

STUDY OBJECTIVES Orexin peptides activate orexin 1 and orexin 2 receptors (OX(1)R and OX(2)R), regulate locomotion and sleep-wake. The dual OX(1)R/OX(2)R antagonist almorexant reduces activity and promotes sleep in multiple species, including man. The relative contributions of the two receptors in locomotion and sleep/wake regulation were investigated in mice. DESIGN Mice lacking orexin recep...

Background: Hyperlipidemia and oxidized-low-density lipoproteins (Ox-LDL) are important independent cardiovascular risk factors that have been shown to stimulate vascular smooth muscle cell (VSMC) proliferation. The purpose of the present study was to investigate the effect of vitamin E on Ox-LDL, lipid profile, C-reactive protein (CRP), and VSMC proliferation of rat aorta. Methods: Male Wistar...

objective: in patients with diabetes mellitus, increased rate of lipoprotein oxidation and oxidative stress have important role in diabetic angiopathy, including nephropathy. we designed a study for comparing the level of ox-ldl in diabetic patients with macro-albuminuria, micro-albuminuria, versus normo-albuminuric. materials and methods: one hundred and thirty five patients with type 2 diabet...

Polysaccharide from Fuzi (FPS) is a water‑soluble polysaccharide isolated from the traditional Chinese herbal medicine Fuzi. It has been demonstrated to protect hepatocytes against ischemia‑reperfusion injury through its potent antioxidant effects, and to attenuate starvation‑induced cytotoxicity in H9c2 cells by increasing autophagic activity. In the present study, Alizarin Red S staining was ...
