Filter by:Bacoxy_I study aims to evaluate the efficacy of a standardized Bacopa monnieri extract, Bacopa-400®, on vascular oxidative stress.
The purpose of this clinical trial is to investigate the efficacy and safety of continuous intravenous administration of low dose iloprost versus placebo for 72-hours, in 450 mechanically ventilated patients with infectious respiratory failure. The study hypothesis is that iloprost may be beneficial as an endothelial rescue treatment as it is anticipated to deactivate the endothelium and restore vascular integrity in patients suffering from respiratory failure caused by endothelial breakdown, ultimately improving survival.
Plasma cardiac troponin (cTn) elevation is an indicator of increased mortality in patients with sepsis yet the underlying cause of troponin elevation in sepsis is not known. The COMTESS study investigates whether elevated high-sensitive cardiac Troponin T (hs-cTnT) levels in hemodynamically unstable patients with sepsis can be explained by an underlying coronary artery disease or a process within the coronary microcirculation. Fifty patients with sepsis and with hs-cTnT elevation (>15 ng/L) will undergo coronary angiography, including an assessment of coronary flow using a method called thermo-dilution to record the index of microcirculatory resistance (IMR) in the left anterior descending artery (LAD). The relationship between IMR and hs-cTnT will subsequently be analysed. It is important to identify the underlying causes of elevated cTn during sepsis to target further research with an aim to improve the survival in patients suffering from this condition.
The study aims to check the influence of krill oil on markers of intestinal injury and intoxication. Research group: the research will be conducted in a homogeneous group of professional rowers (N=30), all competitors qualified for the Polish Youth Rowing Team, aged 18 - 24. The sample size was confiremed in statistical analyses. Rowing performance test will be conducted at the beginning and at the end of the training camp. Participants will perform a test on a rowing ergometer (Concept II, USA); each subject will have to cover a distance of 2000 m in the shortest possible time which is the distance starting in rowing competitions. The results of both tests will be considered in the selection for the championship team; therefore, athletes will be well motivated to perform both tests with maximum effort. Hypotesis: The krill oil will infleunce the gut barier integrity.
The investigators aimed to reveal the relationship between serum markers of pyroptosis, GVHD biomarkers and endothelial damage markers in patients who were planned for allogeneic stem cell transplantation for AML and developed GVHD during follow-up. Secondary outcomes of the study were to demonstrate the role of pyroptosis in the pathophysiology of GVHD and transplantation-associated endothelial injury using serum plasma samples; the efficacy of GVHD biomarkers used to demonstrate organ-specific involvement; and the efficacy of GVHD biomarkers and endothelial injury markers in predicting the development of GVHD, transplantation-associated endothelial injury and non-relapse mortality.
This research is being done to determine whether acute exercise causes differences in numbers of novel blood factors associated with vascular health in college-aged adults across different physical activity habits. As only ~50% of cardiovascular (CV) events can be explained by traditional CV risk factors such as high blood pressure and high cholesterol, it is anticipated that this research will provide a more comprehensive look into novel risk factors that may better explain CV risk and that may be modifiable through regular physical activity.
This is a pilot clinical trial to test the efficacy of intermittent treatment with the flavonoid compound fisetin for improving vascular endothelial function and reducing aortic stiffness in older adults. This trial will also determine the potential mechanisms by which fisetin may improve vascular function, including by decreasing mitochondrial oxidative stress, cellular senescence and senescence-associated secretory phenotype (SASP) factors in circulation. Lastly, safety, tolerability and adherence of fisetin treatment will be assessed.
The glycocalyx serves as the interface between flowing blood and endothelial cells, the single cell layer that lines blood vessels, and is crucial for normal blood vessel function. Specifically, the glycocalyx protects endothelial cells from oxidative stress and inflammation and enables blood vessel dilation, which is largely dependent on the bioavailability of the vasodilatory molecule nitric oxide. Importantly, glycocalyx thickness decreases with age and is predictive of major adverse cardiovascular events in older adults free of cardiovascular disease. Therefore, interventions aimed at restoring glycocalyx thickness in older adults are desperately needed. Endocalyx Pro is a commercially available glycocalyx precursor supplement, manufactured by Microvascular Health Solutions, designed to 1) repair a damaged glycocalyx, 2) protect against damage to the glycocalyx, and 3) synthesize new glycocalyx components, and has been used to increase glycocalyx thickness in humans. However, no study has tested if glycocalyx thickness restores glycocalyx thickness in older adults and improves blood vessel function. Thus, the purpose of this investigation is to determine if 12-weeks of Endocalyx Pro supplementation alters glycocalyx thickness and blood vessel function in older adults. The investigators will use a camera placed under the tongue to determine glycocalyx thickness. The investigators will measure blood vessel function by measuring brachial artery dilation with ultrasound and arterial stiffness using pressure probes placed on the carotid and femoral artery.
Bacoxy_II study aims to evaluate the efficacy of a standardized Bacopa monnieri extract, KeenMind®, on vascular oxidative stress.
This research study seeks to determine the effects of an enzyme in the human body called NADPH oxidase (NOX) on blood flow. In addition, the study will investigate the benefits of creatine monohydrate, a common sports performance supplement, on blood food and vessel function. Participants will undergo two study arms, one in which they consume a high carbohydrate meal pre- and post-creatine monohydrate supplementation and one in which they will consume a high carbohydrate meal pre- and post-placebo supplementation. Blood flow and endothelial function will be assessed before and for 4 hours following the consumption of a high-carbohydrate meal pre and post-supplementation (creatine monohydrate and placebo).
