Filter by:In Romania, the diseases of the circulatory system account for 59.3% of deaths, representing the main cause of morbidity and mortality. Barriers of current pharmacological treatments materialized in side effects and limited actions on risk factors increase the necessity of finding more effective, multi-target and less toxic therapeutic strategies. Considering the well-known benefits, natural compounds represent a very important source for drug candidates. The latest in vitro and in vivo studies on Aronia melanocarpa (Michx.) Elliott have highlighted its antioxidant, anti-inflammatory, anti-proliferative, anti-atherosclerotic, hypotensive, antiplatelet, lipid and glucose reduction properties, making it an excellent candidate for the prevention and treatment of cardiovascular and metabolic disorders. The aim of this study is to comprehensive evaluate (in vivo) the Aronia melanocarpa bio juice, obtained from Romania on blood pressure levels and endothelial damage.
A controlled clinical intervention study is proposed to determine the effect of black garlic consumption on biomarkers of cardiovascular function and associated pathologies in a healthy population at risk for cardiovascular disease. Black garlic is the result of a fermentation process of common white garlic in which the temperature and humidity are kept constant over a long period of time. Black garlic is particularly rich in phenolic compounds such as S-allylcysteine or S-allyl-mercaptocysteine, with antioxidant action. It also provides vitamin C and other valuable antioxidant substances such as flavonoids.
Inorganic nitrate can protect blood vessels from the damage that occurs during cardiovascular disease. Early experimental work suggests that nitrate-induced improvements in vascular function relate to the suppression of inflammatory pathways. Whether this protection against inflammation-induced damage to the blood vessel wall might also be functional in the setting of COVID-19 vaccination will be investigated. Vascular function will be assessed before and after the healthy participant has received their COVID-19-vaccination. Whether there might be differences in the response to the vaccine between the sexes and whether a dietary nitrate intervention impacts upon the effects of vaccination will be investigated. The study is in two parts: Part A: To assess sex differences in the vascular response to COVID-19 vaccination. Part B: To assess whether inorganic nitrate, in the form of dietary inorganic nitrate supplementation compared to placebo control, can raise circulating plasma nitrite levels and thereby prevent the systemic inflammation that causes vascular dysfunction.
The purpose of the study is to find out the effects of neighborhood disadvantage and sleep disparities contribute to racial disparities in cardiometabolic health and blood pressure in young adults.
Exercise training improves walking capacity and regional perfusion in patients with Intermittent Claudication (IC). Endothelial Progenitor Cells (EPCs) and Endothelial Microparticles (EMPs) could play an important role in this process, promoting the healing of the diseased endothelium. The investigators are going to measure EPCs and EMPs in a group of patients with IC and in a control group of healthy individuals before a treadmill test and 2, 24, and 48 hours after the test. Subsequently, a group of IC patients will be randomly assigned to perform a 12-week home-based exercise training program. The investigators expect a significant increase of EMPs and EPCs after acute and chronic physical activity. We expect also a correlation between the increase of EMPs and EPCs and the improvement in walking capacity. Aim of the study is to demonstrate that acutely performed aerobic exercise could be able to promote the mobilization of EMPs and EPCs in patients with IC and that endothelial progenitor cells mobilization could play a pivotal role in exercise induced improvement of walking performance and endothelial function in subjects with IC.
Eligible candidates will be recruited within the children with overweight and obesity having a metabolic risk evaluation before treatment in the period 2006 and 2010 at the pediatric clinic of the UZ Brussel In total 60 participants will be investigated. Firstly, 30 participating patients with initially elevated hsCRP will be selected at random ( following the date of their initial investigation) and afterwards matched for age, BMI z-score, and blood pressure with the same number of patients without initially elevated hCRP values Data will be collected as follows: - questionnaires - clinical examination/ anthropometry - blood sample (hsCRP) - peripheral arterial tonometry (endoPAT)
The aim of this observative, prospective study is to evaluate if and to what extent glycocalyx damage/microcirculation data at admission in the ICU as well as during ICU stay can be predictive of mortality and clinical course in patients presenting with the suspicion of sepsis/septic shock. Therefore, the enrollment of ca 100 ICU patients is planned.
This study investigates the effect of dietary inorganic nitrate supplementation on 1) large elastic artery stiffness and hemodynamics and 2) cerebrovascular function in middle-aged and older adults. Participants will be randomized to consume either nitrate-containing or nitrate-depleted beetroot juice.
The proposed research is clinical study evaluating the therapeutic benefits of resveratrol on vascular function in patients with chronic kidney disease (CKD). The study aims to establish that resveratrol will improve endothelial function and functional performance by reducing oxidative stress and in conjunction with lowering markers of inflammation and oxidative stress.
The purpose of this study is to investigate the effects of acute intravenous iron administration on the endothelial function in non-dialysis Chronic Kidney Disease stages G3-G5 patients with anemia and iron deficiency, in relation to changes in oxidative and nitrosative status.
