We undertook a genome-wide association study (GWAS) of parental longevity in European descent UK Biobank participants. For combined mothers' and fathers' attained age, 10 loci were associated (p<5*10-8), including 8 previously identified for traits including survival, Alzheimer's and cardiovascular disease. Of these, 4 were also associated with longest 10% survival (mothers age ≥90 years, fathers ≥87 years), with 2 additional associations including MC2R intronic variants (coding for the adrenocorticotropic hormone receptor)...

Populations living in radiation-contaminated territories, such as Chernobyl and Fukushima, are chronically exposed to external gamma radiation and internal radionuclide contamination due to the large amount of 137Cs released in the environment. The effect of chronic low-dose exposure on the development of cardiovascular diseases remains unclear. Previously reported studies have shown that low-dose radiation exposure could lead to discrepancies according to dose rate. In this study, we examined the effect of very low-dose and dose-rate chronic external exposure on atherosclerosis development...

Bioactive polyphenolic compounds derived from plants are being utilized for prevention of various chronic diseases including cancer and cardiovascular disorders. Quercetin, a potential poly-phenolic flavonol, found in onions, apples and berries, has been implicated against cancer proliferation, chronic inflammation and various other oxidative manifestations. Evidences suggested that quercetin negatively regulates the numerous crucial signaling pathways associated with life-threatening diseases. Major signaling pathways including NF-κB, MAPK, PI3K-AKT and mTOR are found to be regulated by quercetin...

Systemic inflammation induced by bacterial infection is one of several causative agents for cardiovascular disorders in patients with periodontal disease. Experimental results indicate that miRNAs play important roles in systemic inflammation induced by endotoxins. Further evidence states that stem cell based therapy shows potential in the treatment of inflammatory responses induced by sepsis. This study investigates if stem cells show protective effects on cardiomyocyte damage induced by porphyromonas gingivalis-LPS (Pg-LPS) through regulating miRNAs...

BACKGROUND: Endothelial progenitor cells (EPCs) repair damaged vascular endothelium and low circulating EPC levels have been associated with cardiovascular disease (CVD). CD34+/KDR+ EPCs are commonly reported in literature and CD34+/CD133+/KDR+ EPCs are rare in circulation but highly specific for endothelial lineage. HIV-infected (HIV+) adults have chronic inflammation and increased CVD risk, but the relationship between CVD, vascular inflammation and EPCs in HIV remains unclear. METHODS: In a pilot study, EPCs were measured in 57 HIV+ men (≧50 years old, HIV-1 RNA <50 copies/mL on ART) by real-time flow cytometry using cellular immaturity (CD34 and/or CD133) and endothelial commitment (KDR) markers...

BACKGROUND: Homoarginine (hArg) is known to have an impact on nitric oxide (NO) metabolism. It seems to increase NO generation and/or availability, thereby enhancing endothelial function. In addition, hArg is connected to energy metabolism since the key enzyme, L-arginine-glycine amidinotransferase (AGAT) for hArg synthesis in the kidneys, is also involved in the synthesis of energy metabolites like guanidinoacetate. Former studies indicate that low levels of hArg are linked to cardiovascular disease and increased all-cause mortality...

Hepatitis C (HCV) infection has an estimated global prevalence of 2.5%, causing chronic liver disease in 170 million people worldwide. Recent data has identified HCV infection as a risk factor for subclinical and clinical cardiovascular disease (CVD), but these data have been mixed and whether HCV is an independent risk factor for development of CVD remains controversial. In this review, we present the literature regarding the association of HCV with subclinical and clinical CVD and the possible underlying mechanisms leading to increased CVD among those infected with HCV...

Background: Cardiovascular disease is the most common cause of mortality in haemodialysis (HD) patients and is highly predicted by markers of chronic inflammation. Regular exercise may have beneficial anti-inflammatory effects, but this is unclear in HD patients. This study assessed the effect of regular intradialytic exercise on soluble inflammatory factors and inflammatory leucocyte phenotypes. Methods: Twenty-two HD patients from a centre where intradialytic cycling was offered thrice weekly and 16 HD patients receiving usual care volunteered...

Abdominal aortic aneurysm (AAA) is a fatal disease that is associated with chronic inflammation in the vessel wall. Cortistatin is implicated in inflammation, vascular smooth muscle cell migration and other cardiovascular pathologies. But, the hypothetical effect of cortistatin on AAA remains uncertain. We investigated the effect of cortistatin administration to angiotensin (Ang) II-induced AAA formation in apolipoprotein E deficient (Apoe-/-) mice. We showed that cortistatin administration significantly suppresses incidence and severity of AAA in Apoe-/- mice...

ETHNOPHARMACOLOGICAL RELEVANCE: Tartary buckwheat is a food medicine dual-use crop with healing effects on cardiovascular diseases and type2 diabetes. It has been proposed that endothelial dysfunction is the initial lesion in these diseases and it's associated with mitochondrial dysfunction, endoplasmic reticulum (ER) stress and inflammation. D-chiro-inositol (DCI) is a bioactive compound of Tartary buckwheat and is always deficit in type2 diabetes. However, it remains unknown whether DCI-enriched Tartary buckwheat extract can ameliorate mitochondrial dysfunction, ER stress and inflammation in the endothelium...

A wide variety of chronic diseases, such as neurodegenerative and cardiovascular disorders, diabetes mellitus, osteoarthtitis, obesity and various cancers, are now being treated with cost effective phytomedicines. Since synthetic medicines are very expensive, concerted efforts are being made in developing and poor countries to discover cost effective medicines for the treatment of non-communicable diseases (NCDs). Understanding the underlying mechanisms of bioactive medicines from natural sources would not only open incipient avenues for the scientific community and pharmaceutical industry to discover new drug molecules for the therapy of NCDs, but also help to garner knowledge for alternative therapeutic approaches for the management of chronic diseases...

Currently, there is increasing attention towards flavonoids and phenolic compounds of plant origin because of their association with decrease in the incidence of cardiovascular diseases and different types of cancer. The present study investigates the protective effect of Clerodendrum volubile (C. volubile) methanolic extracts against carbon tetrachloride (CCl4)-induced hepatotoxicity in rats. Control rats (group I) received olive oil (1 mL/kg, i.p.), group II received CCl4 in olive oil (1 ml/kg, i.p.) to induce hepatotoxicity, groups III, IV and V were pretreated with leaf extract of C...

Effective pharmaceutical treatments for age-related cognitive decline have proved elusive. There is, however, compelling evidence that nutritional status and supplementation could play crucial roles in modifying the expression of cognitive change through the lifespan. Subjective memory impairment and mild cognitive impairment can be harbingers of dementia but this is by no means inevitable. Neurocognitive change is influenced by a variety of processes, many of which are involved in other aspects of systemic health, including cardiovascular function...

Cytosine methylation has been shown to have a role in a host of biological processes. In mammalian biology these include stem cell differentiation, embryonic development, genomic imprinting, inflammation, and silencing of transposable elements. Given the central importance of these processes, it is not surprising to find aberrant cytosine methylation patterns associated with many disorders in humans, including cancer, cardiovascular disease, and neurological disease. While whole genome shotgun bisulfite sequencing (WGBS) has recently become feasible, generating high sequence coverage data for the entire genome is expensive, both in terms of money and analysis time, when generally only a small subset of the genome is of interest to most researchers...

There is evidence for blood inflammatory abnormalities in patients with first-episode psychosis (FEP). The monocyte- and neutrophil-to-lymphocyte ratios (MLR; NLR) are markers of inflammation and endothelial dysfunction, and predictors of cardiovascular disease, the leading cause of death in schizophrenia. We investigated relationships between white blood cell (WBC) counts and hemodynamic parameters associated with cardiovascular disease risk in 25 subjects age 18-50 hospitalized for FEP and 44 controls. Subjects had a blood draw, vital signs, and medical history...

Obesity is a high risk factor for diseases such as cardiovascular, metabolic syndrome and asthma. Obese-asthma is another emerging phenotype in asthma which is typically refractive to steroid treatment due to its non-classical features such as non-eosinophilic cellular inflammation. The overall increased morbidity, mortality and economical burden in asthma is mainly due to steroid resistant asthma. In the present study, we used high fat diet induced obese mice which when sensitized with house dust mite (HDM) showed steroid resistant features...

Exposure to psychosocial stress is a risk factor for cardiovascular disease, including vascular aging and regeneration. Dipeptidyl peptidase-4 (DPP-4) exerts many physiological and pharmacological functions by regulating its extremely abundant substrates [e.g., glucagon-like peptide-1 (GLP-1), stromal cell-derived factor-1α/ C-X-C chemokine receptor type-4, etc.]. Over the past decade, emerging data revealed unexpected roles for DPP-4 and GLP-1 in intracellular signaling, oxidative stress production, lipid metabolism, cell apoptosis, immune activation, insulin resistance, and inflammation...

OBJECTIVE: We aimed at summarizing current evidence about mechanisms for potentially harmful effects of proton pump inhibitors (PPIs). METHODS: A Pubmed search was performed, and 207 studies concerning the relationship between use of PPIs and cardiovascular diseases, kidney impairment, nutritional disorders, fractures, infections, functional decline, and mortality were selected and reviewed. RESULTS: PPIs may cause potentially harmful effects by several mechanisms, including endothelial dysfunction, hypomagnesemia, drug interactions, reduced absorption of selected nutrients, increased gastric microbiota and small intestine bacterial overgrowth, reduced immune response, tubular-interstitial inflammation, increased bone turnover, accumulation of amyloid in the brain...

Exposure to dioxins and related persistent organic pollutants likely contributes to cardiovascular disease (CVD) risk through multiple mechanisms including the induction of chronic inflammation. Epidemiological studies have shown that leaner individuals may be more susceptible to the detrimental effects of lipophilic toxicants because they lack large adipose tissue depots that can accumulate and sequester these pollutants. This phenomenon complicates efforts to study mechanisms of pollutant-accelerated atherosclerosis in experimental animal models where high-fat feeding and adipose expansion limit the bioavailability of lipophilic pollutants...

Sex-related differences in cardiovascular health and disease have been identified with males having a higher incidence of cardiovascular events but females more likely to develop arrhythmias. Adverse fetal environments are now accepted as a cause for the development of cardiovascular diseases in adulthood but sex-related differences in response to adverse fetal environments have not been extensively explored. The combination of both in utero and postnatal exposure to inflammation is highly clinically relevant for the infant that is born preterm or has clinical complications at birth or early postnatal life...
