Background: High-fat meals induce postprandial inflammation. Resveratrol is a polyphenol known to prevent comorbidities associated with cardiovascular disease and exerts an anti-inflammatory action. There is also an increasing body of evidence supporting the role of curcumin, a polyphenol from the curcuminoid family, as a modulator of proinflammatory processes. Objective: The objectives of this study were to investigate the following: 1) the bioavailability of resveratrol consumed in combination with curcumin after consumption of a high-fat meal; and 2) the acute combined effects of this combination on the postprandial inflammatory response of subjects with abdominal obesity...

Neonatal necrotizing enterocolitis (NEC) is a severe acquired disease that predominantly affects the small intestine of neonates. NEC is caused by a combination of metabolic products, dysfunctions of the blood vessels, mucus and other unknown factors. Berberine may induce beneficial effects on necrotic and cardiovascular diseases due to its anti-inflammatory and anti-apoptotic effects on epithelial cells. In the present study, the therapeutic effects of berberine were investigated and the potential mechanisms by which it functions within a neonatal NEC mouse model were analyzed...

Tissue Factor is a cell-surface glycoprotein expressed in various cells of the vasculature and is the principal regulator of the blood coagulation cascade and hemostasis. Notably, aberrant expression of Tissue Factor is associated with cardiovascular pathologies such as atherosclerosis and thrombosis. Here, we sought to identify factors that regulate Tissue Factor gene expression and activity. Tissue Factor gene expression is regulated by various transcription factors, including activating protein-1 and nuclear factor-kappa B...

Background and objective: Chronic inflammatory is involved in the development of salt-sensitive hypertension and other cardiovascular diseases. PSGL-1 plays an important role in the inflammatory response. Methods and results: In this study, we used PSGL-1-/- and PSGL-1+/+ mice fed with high salt diet to measure the blood pressure, inflammatory response and vascular injury. We found that, in PSGL-1+/+ mice, high salt diet resulted in high blood pressure with the increased expression of serum inflammatory cytokines IL-6, IL-1β and TNFɑ, vascular injury markers MCP-1, ET-1, and VWF, and renal macrophages and T cells infiltration, and endothelium-dependent acetylcholine vasodilation dysfunction...

Hypertension is a leading cause of cardiovascular mortality, but only about half of patients on antihypertensive therapy achieve blood pressure control. Preeclampsia is defined as pregnancy-induced hypertension and proteinuria, and is associated with increased maternal and perinatal mortality and morbidity. Similarly, a large number of patients with preeclampsia are non-responsive to antihypertensive therapy. Pharmacogenomics may help to guide the personalized treatment for non-responsive hypertensive patients...

Metabolic, inflammatory and functional changes occur in cardiovascular aging which may stem from oxidative stress and be remediable with antioxidants. Glutathione, an intracellular antioxidant, declines with aging, and supplementation with glutathione precursors, N-Acetyl Cysteine (NAC) and Glycine (Gly), increases tissue glutathione. Thirty month-old mice were fed diets supplemented with NAC or NAC+Gly and, after seven weeks, cardiac function and molecular studies were performed.The NAC+Gly supplementation improved diastolic function, increasing peak early filling velocity, and reducing relaxation time, left atrial volume, and left ventricle end diastolic pressure...

Heart failure (HF) is a leading cause of morbidity and mortality in the western world. Although optimal medical care and treatment is widely available, the prognosis of patients with HF is still poor. Toll-like receptors (TLRs) are important compartments of the innate immunity. Current studies have identified TLRs as critical mediators in cardiovascular diseases. In the present study, we investigated the involvement of TLRs and interferon (IFN) regulatory factors (IRFs) in different experimental HF models including viral myocarditis, myocardial ischemia, diabetes mellitus, and cardiac hypertrophy...

OBJECTIVE: Endothelial dysfunction is central to the pathogenesis of many rheumatic diseases, typified by vascular inflammation and damage. Immunosuppressive drugs induce disease remission and lead to improved patient survival. However, there remains a higher incidence of cardiovascular disease in these patients even after adequate disease control. The purpose of this study was to determine the effect of mycophenolic acid (MPA), a commonly used immunosuppressive drug in rheumatology, on blood vessel or circulating endothelial colony forming cell number and function...

BACKGROUND: Late exercise preconditioning (LEP) is confirmed to have a protective effect on acute cardiovascular stress. However, the mechanisms by which mitophagy participates in EP-induced cardioprotection remain unclear. LEP may involve mitophagy mediated by the receptors PARK2 gene-encoded E3 ubiquitin ligase (Parkin) and BCL2/adenovirus E1B 19 kDa protein-interacting protein 3 (Bnip3) to scavenge damaged mitochondria. METHODS: Our exercise preconditioning (EP) protocol involved four 10-minute periods of running, separated by 10-minute recovery intervals, plus a period of exhaustive running at 24 hours after EP...

α1A- and α1B-adrenoceptors (α1A-AR and α1B-AR) are closely related G protein-coupled receptors (GPCRs) that modulate the cardiovascular and nervous systems in response to binding epinephrine and norepinephrine. The GPCR gene super-family is made up of numerous sub-families that, like α1A-AR and α1B-AR, are activated by the same endogenous agonists but may modulate different physiological processes. A major challenge in GPCR research and drug discovery is determining how compounds interact with receptors at the molecular level, especially to assist in the optimization of drug leads...

Alternative splicing (AS) of protein-coding messenger RNAs is an essential regulatory mechanism in eukaryotic gene expression that controls the proper function of proteins. It is also implicated in the physiological regulation of mitochondria and various ion channels. Considering that mis-splicing can result in various human diseases by modifying or abrogating important physiological protein functions, a fine-tuned balance of AS is essential for human health. Accumulated data highlight the importance of alternatively spliced isoforms in various diseases, including neurodegenerative disorders, cancer, immune and infectious diseases, cardiovascular diseases, and metabolic conditions...

BACKGROUND AND AIMS: Uncorrected obesity contributes to cardiac remodeling and contractile dysfunction although the underlying mechanism remains poorly understood. Mitochondrial aldehyde dehydrogenase (ALDH2) is a mitochondrial enzyme with some promises in a number of cardiovascular diseases. This study was designed to evaluate the impact of ALDH2 on cardiac remodeling and contractile property in high fat diet-induced obesity. METHODS: Wild-type (WT) and ALDH2 transgenic mice were fed low (10% calorie from fat) or high (45% calorie from fat) fat diet for 5 months prior to the assessment of cardiac geometry and function using echocardiography, IonOptix system, Lectin, and Masson Trichrome staining...

Surveys indicated that 24% of military personnel are current cigarette smokers. Smoking is well known to increase the risk of cancers, cardiovascular and respiratory diseases, reproductive problems, and other medical maladies, but one of the little known effects of smoking is that on injuries. There is considerable evidence from a variety of sources that (1) smoking increases overall injury risk, (2) the greater the amount of smoking, the higher is the injury risk, and (3) smoking is an independent injury risk factor...

The "HDL hypothesis" supporting that an elevation in HDL cholesterol (HDL-C) levels by drugs or by life style changes should be paralleled by a decrease in the risk for Cardiovascular Disease (CVD) has been challenged by recent epidemiological and clinical studies using HDL-raising drugs. HDL components such as proteins, lipids or small RNA molecules, but not cholesterol itself, possess various atheroprotective functions in different cell types and accumulating evidence supports the new hypothesis that HDL functionality is more important than HDL-C levels for CVD risk prediction...

Background: Familial hypercholesterolemia (FH) is a disorder that is inherited by autosomal dominant pattern. The main cause of FH disease is the occurrence of mutations in low-density lipoprotein receptor (LDLR) gene sequence, as well as apolipoprotein B and proprotein convertase subtilisin/kexin type 9 genes, located in the next ranks, respectively. Materials and Methods: Forty-five unrelated Iranian patients with FH were screened using a high-resolution melting (HRM) method for exon 9 along with intron/exon boundaries of LDLR gene...
