MicroRNAs (miRNAs) exhibit various roles in multiple biological processes and abnormal expression of miR-182-5p has been involved in many diseases. However, the role miR-182-5p in Atherosclerosis (AS) remains poorly understood. In our current investigation, an AS model was established by using oxidized low-density lipoprotein (ox-LDL) in RAW264.7 cells. miR-182-5p was markedly decreased in AS model dose-dependently and time-dependently. Additionally, CD36, oil-red staining levels, TC and TG were inhibited by miR-182-5p mimics, meanwhile ROS levels, MDA and cell apoptosis were also restrained with an enhancement of SOD activity...

Vascular endothelial dysfunction plays an important role in the process of atherosclerosis up to the final stage of plaque rupture. Vascular endothelial dysfunction is reversible, and can be recovered by medications and life-style changes. Improvement in endothelial function may reduce cardiovascular events and improve long-term prognosis. A total of 50 patients with stable angina and dyslipidemia were enrolled, including patients who had not received prior treatment with statins and had serum LDL-C levels ≥ 100 mg/dL, and patients who had previously received statin treatment...

Based on the existing data in grapes and wine, the aim of the present study was to investigate the probability that raisins improve clinical features and markers of oxidative stress, inflammation and arterial function in healthy smokers. Thirty-six apparently healthy smokers were recruited to an open-label and randomized, controlled, 4-week prospective intervention. All participants were reported to consume less than the recommended amount of five servings fruits and vegetables daily. Participants in the intervention were instructed to consume raisins equal to five fruit servings (90g/d)...

The study was conducted to evaluate the effect of dietary phospholipids (PLs) on growth, lipid metabolism, and antioxidative status of hybrid snakehead (Channa argus × Channa maculata). Five isonitrogenous and isolipidic diets with graded levels of PLs (8.5, 19.3, 30.7, 41.5, and 50.8 g kg(-1)) were fed to triplicate groups of juveniles (initial body weight 12.6 ± 0.23 g) for 8 weeks. Results showed that dietary PL supplementation significantly improved growth of juveniles. The final body weight (FBW) and specific growth rate (SGR) significantly increased with dietary PLs increasing from 8...

Diabetes is often associated with decreased melatonin level. The aim was to investigate the effects of different dosage of melatonin on glucose hemostasis, antioxidant ability and adipokines secretion in diabetic institute for cancer research (ICR) mice. Forty animals were randomly divided into five groups including control (C), diabetic (D), low-dosage (L), medium-dosage (M), and high-dosage (H) groups. Groups L, M, and H, respectively, received oral melatonin at 10, 20, and 50 mg/kg of BW (body weight) daily after inducing hyperglycemia by nicotinamide (NA)/ streptozotocin (STZ)...

Vulnerable plaque disruption was suggested as a primary cause of acute coronary syndrome. This study investigated the impact of malondialdehyde-modified low-density lipoprotein (MDA-LDL) on whole coronary plaque vulnerability, based on multislice-computed tomography (MSCT). We included 197 patients that were not receiving lipid-lowering therapy. We retrospectively analyzed MSCT and MDA-LDL measurements. We defined a CT-derived vulnerable plaque as a plaque with a remodeling index > 1.10 and a mean CT density value < 30 HU...

This study was to develop a novel strategy for the simultaneous consumption of soluble soybean polysaccharides (SSPS) to enhance the absorption of genistein and its protective effects against high l-carnitine-induced hepatic injury in mice. UPLC-qTOP/MS measurements showed that SSPS observably increased the urinary concentration of genistein and its metabolites in mice. The mice fed with 3% l-carnitine water for 12 weeks experienced a disturbance of the hepatic lipid metabolism, oxidative stress and inflammation, which was evidenced by abnormal TC, LDL, RAHFR and MDA levels, unusual AST, ALT, ALP, SOD and GSP-Px activities, and increased IF-1, IF-6 and TNF-α expressions...

Wheat bran, an abundant byproduct of the milling industry, comprises fat-soluble bioactives and fibers. In the present study, two concentrates were prepared from wheat bran oil (WBO) using silicic acid coupled with acetone (WBA) and hexane (WBH). WBA extract had enhanced color and viscosity and was enriched with fat-soluble bioactives (sterols, oryzanol-like compounds, tocopherols, and carotenoids) as evidenced from NMR and other techniques. In in vitro studies, WBA exhibited significant free radical scavenging activity, limited DNA and LDL oxidation, and inhibiting HMG-CoA reductase and lipase activity better than WBH and WBO...
