Anti-Atherosclerotic and Anti-Inflammatory Effects of Curcumin on Hypercholesterolemic Male Rabbits

AbstractCurcumin has a potent antioxidant and anti-inflammatory properties that may suppress inflammatory component of atherosclerosis. It has been demonstrated that curcumin derivatives can reduce the formation of arterial fatty streaks in cholesterol-fed rabbits. Therefore in this study we evaluated the protective effects of Curcumin on the progression of atherosclerosis. 20 mature rabbits were included for this study; they were randomly divided into four groups each of 5. Group 1: (normal control) were fed corn pellets diet and tab water, group 2: (high cholesterol diet control) were kept on cholesterol rich diet (2% cholesterol) and tab water. Group 3: (cholesterol and rosuvastatin treated group) were kept on cholesterol rich diet (2% cholesterol) and 2.5  mg/kg/day Rosuvastatin dispersed in DW and given orally, group 4: (cholesterol and curcumin treated group) were kept on cholesterol rich diet (2% cholesterol) and 0.2% curcumin added with corn pellets. The study continued for 12 weeks then assessment of serum level of high sensitive C-reactive pr otein, ICAM1, VCAM1 and PCSK9 was carried out at the end of the study. Total antioxidant activity of curcumin was also determined. Histopathological examination of aortic tissues for atherosclerotic changes was also carried out. Atherogenic (cholesterol rich diet) induced an increment in serum level of TC, LDL, VLDL and TG with concomitant decrement in serum level of HDL and increased atherogenic index. Treatment with...

Authors: Schulte C, Zeller T Abstract Cardiovascular (CV) risk assessment is based on the utilization of risk scores, enabling clinicians to estimate an individual's risk to develop CV pathologies and events. Such risk scores comprise classic CV risk factors such as smoking, diabetes, hypertension, and blood cholesterol levels. Recently, other CV biomarkers such as cardiac troponins have been suggested and evaluated as alternative biomarkers not only in the acute diagnostic setting of myocardial infarction, but also as markers for risk stratification in the general population. In this review, we summarize the curre...

Publication date: Available online 7 December 2019Source: Microbial PathogenesisAuthor(s): Philippe Bercier, Marcelo Gottschalk, Daniel GrenierAbstractStreptococcus suis is a bacterial pathogen that mainly colonizes the upper respiratory tract of pigs. It is known to cause severe infections such as septicemia, meningitis, arthritis, and endocarditis in pigs and to be responsible for major economic losses in the swine industry worldwide. To better understand the interactions between S. suis and the porcine respiratory epithelium, we investigated the ability of this pathogen to cause damage to the tracheal epithelial barrier...

ViraniBackgroundStatin use remains suboptimal in patients with atherosclerotic cardiovascular disease (ASCVD). We assessed if the frequency of visits with primary care providers (PCPs) is associated with higher use of evidence-based statin prescriptions and adherence among patients with ASCVD.MethodsWe identified patients with ASCVD aged ≥18 years rec...

CONCLUSIONS: This study did not support an association between statin use and diagnostic conversion but suggested a possible association between statin use and cognitive change in EMCI. Additional randomized clinical trials of statins may be warranted in the prodromal EMCI stage of AD. PMID: 31806426 [PubMed - as supplied by publisher]

Authors: Sevim E, Willis R, Erkan D Abstract Antiphospholipid syndrome (APS) is a systemic autoimmune disorder characterized by thrombosis, pregnancy morbidity, or nonthrombotic manifestations in patients with persistently positive antiphospholipid antibodies (aPL). Conventional APS treatment focuses on antithrombotic strategies, which are usually ineffective for the microvascular and nonthrombotic manifestations of aPL. Using a case-based presentation, this review focuses on the role of immunosuppression in nonobstetric APS, including B-cell inhibition (rituximab, belimumab, and bortezomib), complement inhibition ...

In this study we investigated the interaction of astringent polyphenols, namely ECG, EGCG, procyanidin B4 and PGG, with lipids in model membranes by spectroscopic techniques. The membrane model was built varying the cholesterol content to mimic mouth regions and experiments were conducted at pH 5 to mimic the pH drop at the moment of beverage (e.g. green tea, red wine) intake.Fluorescence quenching results conducted on LUVs with cholesterol molar fractions ranging between 0.34
