The presence of oral inflammation has recently been linked with the pathogenesis of cardiovascular diseases. Endothelial dysfunction is considered one of the pathogenetic mechanisms of a whole range of cardiovascular diseases. In the study describes links between periodontitis and endothelial dysfunction. 32 patients (16 boys and 16 girls) with periodontitis and 60 healthy children were examined. Flow-mediated vascular dilatation data were measured in all patients. Flow-mediated dilatation was 9,78±3,16% in children with periodontitis, and 12,85±3,48% in healthy children (p<0,05). Area under the dilation curve was larger in healthy children, then in children with periodontitis, 710±121%·с in comparison with 519±175%·с (p<0,05). An inverse correlation was found between flow-mediated dilatation, area under the dilation curve and periodontitis duration (r = -0,71, -0,77). A negative correlation was found between flow-mediated dilatation, area under the dilation curve and worsening of periodontitis (r = -0,70, -0,71). This study did not demonstrate association between periodontal disease in children and arterial hypertension, coronary heart disease, heart failure. However, the identified endothelial dysfunction requires protective therapeutic and preventive measures. Given the insignificant symptoms of chronic periodontitis in the examined children, it is important to activate efforts aimed at early detection and treatment of this disease. Further research is needed to clarify the prognostic role of endothelial dysfunction in chronic periodontitis.

Cardiovascular diseases (CVDs) are the most common cause of morbidity and mortality worldwide. The potential benefits of natural antioxidants derived from supplemental nutrients against CVDs are well known. Remarkably, natural antioxidants exert cardioprotective effects by reducing oxidative stress, increasing vasodilation, and normalizing endothelial dysfunction. Recently, considerable evidence has highlighted an important role played by the synergistic interaction between endothelial nitric oxide synthase (eNOS) and sirtuin 1 (SIRT1) in the maintenance of endothelial function. To provide a new perspective on the role of natural antioxidants against CVDs, we focused on microRNAs (miRNAs), which are important posttranscriptional modulators in human diseases. Several miRNAs are regulated via the consumption of natural antioxidants and are related to the regulation of oxidative stress by targeting eNOS and/or SIRT1. In this review, we have discussed the specific molecular regulation of eNOS/SIRT1-related endothelial dysfunction and its contribution to CVD pathologies; furthermore, we selected nine different miRNAs that target the expression of eNOS and SIRT1 in CVDs. Additionally, we have summarized the alteration of miRNA expression and regulation of activities of miRNA through natural antioxidant consumption.

The endothelium plays a pivotal role in vascular homeostasis, and endothelial dysfunction is a major feature of cardiovascular diseases, such as arterial hypertension, atherosclerosis, and diabetes. Recently, uridine adenosine tetraphosphate (Up4A) has been identified as a novel and potent endothelium-derived contracting factor (EDCF). Up4A structurally contains both purine and pyrimidine moieties, which activate purinergic receptors. There is an accumulating body of evidence to show that Up4A modulates vascular function by actions on endothelial and smooth muscle cells. In this paper, we discuss the effects of Up4A on vascular function and a potential role for Up4A in cardiovascular diseases.

BACKGROUND Endothelial dysfunction is an early event in the development and progression of a wide range of cardiovascular diseases. Various human studies have identified that measures of endothelial dysfunction may offer prognostic information with respect to vascular events. Microparticles (MPs) are a heterogeneous population of small membrane fragments shed from various cell types. The endothelium is one of the primary targets of circulating MPs, and MPs isolated from blood have been considered biomarkers of vascular injury and inflammation. CONTENT This review summarizes current knowledge of the potential functional role of circulating MPs in promoting endothelial dysfunction. Cells exposed to different stimuli such as shear stress, physiological agonists, proapoptotic stimulation, or damage release MPs, which contribute to endothelial dysfunction and the development of cardiovascular diseases. Numerous studies indicate that MPs may trigger endothelial dysfunction by disrupting production of nitric oxide release from vascular endothelial cells and subsequently modifying vascular tone. Circulating MPs affect both proinflammatory and proatherosclerotic processes in endothelial cells. In addition, MPs can promote coagulation and inflammation or alter angiogenesis and apoptosis in endothelial cells. SUMMARY MPs play an important role in promoting endothelial dysfunction and may prove to be true biomarkers of disease state and progression.

Epilepsy is a disease arising from morphological and metabolic changes in the brain. Approximately 60% of patients with seizures can be controlled with 1 antiepileptic drug (AED), while in others, polytherapy is required. The AED treatment affects a number of biochemical processes in the body, including increasing the risk of cardiovascular diseases (CVDs). It is indicated that the duration of AED therapy with some AEDs significantly accelerates the process of atherosclerosis. Most of AEDs increase levels of homocysteine (HCys) as well as may affect concentrations of new, nonclassical risk factors for atherosclerosis, that is, asymmetric dimethylarginine (ADMA) and homoarginine (hArg). Because of the role of these parameters in the pathogenesis of CVD, knowledge of HCys, ADMA, and hArg concentrations in patients with epilepsia treated with AED, both pediatric and adult, appears to be of significant importance.

Introduction: The review provides relevant information about arginase 2, the role of this enzyme in the formation of endothelial dysfunction and, as a consequence, the development of cardiovascular diseases. History of the discovery of arginase and its functions: The discovery of arginase took place long before its active study as a substance that affects the formation of endothelial dysfunction. Role of arginase 2 in the development of a number of cardiovascular diseases: The role of NO synthase and arginase 2 in the formation of oxidative stress is determined. The pathophysiological mechanisms of the development of a number of cardiovascular diseases, such as coronary heart disease, atherosclerosis, and aortic aneurysm, are described. The modern possibilities of treatment of endothelial dysfunction in the pathology of the cardiovascular system and the possibility of creation of new drugs are considered. An increase in the activity of arginase 2 was proven to occur in the case of the development of coronary heart disease (CHD), hypertension, type II diabetes mellitus, hypercholesterolemia, as well as in the process of aging. According to the WHO, coronary heart disease and apoplectic attack have topped the list of causes of death worldwide over the past 15 years. Arginase 2 as a potential pharmacological target: The purpose of this literature review is to determine the possibilities of use of arginase 2 as a new target for the pharmacological correction of cardiovascular diseases.

Cardiovascular disease remains the leading cause of mortality accounting up to 40% of all deaths, but, currently, cancer is prominent cause of death globally. Anthracyclines are the cornerstone of chemotherapy in women with breast cancer. However, its clinical use is limited by their cardiotoxic effects that can trigger heart failure development. Vascular toxicity of chemotherapy may be linked with endothelial dysfunction because anthracycline damage of endothelial cells can lead to the development and progression of cardiomyopathy by decreasing the release and activity of endothelial factors and, ultimately, endothelial cell death. These processes suppress anti-inflammatory and vascular reparative functions and initiate the development of future cardiovascular events. Recent studies have shown that chemotherapy may induce toxicity in the vascular endothelium and is accompanied by systemic endothelial dysfunction in patients with diagnosed cardiovascular diseases. Because the initial endothelial cell insult is likely asymptomatic, there is often a long delay between the termination of doxorubicin therapy and the onset of vascular disorders. In this case, genetic susceptibility factor will help to identify susceptible patients in the future. The objectives of this study were to evaluate prognostic role of molecular (endothelin-1) and genetic factors (gene polymorphisms of endothelial nitric oxide (NO) synthase (NOS3, rs1799983), endothelin-1 receptor type A (EDNRA, C+70G, rs5335) and NADPH oxidase (C242T, rs4673) in development of endothelial dysfunction and anthracycline-induced cardiotoxicity in women without cardiovascular diseases.

Many factors have been implicated in the pathogenesis of hypertension, including changes in intracellular concentrations of calcium, sodium, potassium, and magnesium. There is a significant inverse correlation between serum magnesium and incidence of cardiovascular diseases. Magnesium is a mineral with important functions in the body such as antiarrhythmic effect, actions in vascular tone, contractility, glucose metabolism, and insulin homeostasis. In addition, lower concentrations of magnesium are associated with oxidative stress, proinflammatory state, endothelial dysfunction, platelet aggregation, insulin resistance, and hyperglycemia. The conflicting results of studies evaluating the effects of magnesium supplements on blood pressure and other cardiovascular outcomes indicate that the action of magnesium in the vascular system is present but not yet established. Therefore, this mineral supplementation is not indicated as part of antihypertensive treatment, and further studies are needed to better clarify the role of magnesium in the prevention and treatment of cardiovascular diseases.
