Nutrition and vascular function.
… the risk of atherosclerosis through altering vascular function. Modification of dietary intake and weight loss can ameliorate these risk factors and may impede the development of atherosclerosis. CVD risk can be assessed by measurement of both traditional e.g. lipid levels, glucose and blood …

Novel Interventions to Improve Cerebral and Peripheral Vascular Function
Cardiovascular diseases (CVD) are major causes of morbidity and mortality worldwide. Complications associated with CVD encompass the entire vascular system, including blood vessels that supply brain. Impairments to cerebral blood flow (CBF) and cerebrovascular function result in increased risk of …

Exercise and peripheral vascular function in health and disease
… origin” [1]. Knowledge that one’s risk for cardiovascular events is related to the severity of endothelial dysfunction, and evidence that exercise training can improve endothelial function, has prompted speculation that measures of vascular function may serve as a “barometer” for cardiovascular …

Mechanisms of soy isoflavones in the regulation of vascular function
Cardiovascular diseases (CVD) are the leading cause of morbidity and mortality in the United States. It is also well recognized that the incidence of CVD is substantially increased in postmenopausal women due to the loss of estrogen. Experimental and clinical data support vascular protective …

Measurement of Cerebral Metabolism and Vascular Function with Magnetic Resonance Imaging
The brain relies on oxidative metabolism to function properly. Cerebral metabolic rate of oxygen (CMRO2) is thus an important marker for brain health. Existing techniques for quantification of CMRO2 with positron emission tomography (PET) or magnetic resonance imaging (MRI) involve special …

Characterisation of cardiac cellular and vascular function in Ischemic heart disease
… mostchronic cases of IHD are focused on the revascularisation of the ischemic region and the subsequentrestoration of blood flow. As such, the most prevalent therapeutic option is the coronary artery bypassgraft (CABG). In these procedures, the internal mammary artery (IMA) is deemed to be the …

Effects of Far Infrared Irradiation on Vascular Function in Healthy Subjects
… aims to investigate the effects of FIR on the vascular function in healthy subjects. This study will also explore some of the mechanisms including anti-oxidation and an endothelium-related gene that might be explained by FIR effects.<b><br/></b><b><br/></b><b>Methods</b>: in this thesis, 70 …

Understanding the Effects of Acute Stevia Consumption on Vascular Function in Humans
… sweeteners has been associated with impaired vascular functioning and other negative health outcomes (Liu et al., 2012; Meziat et al., 2016; Pearlman et al., 2017; Schiano et al., 2020; Suez et al., 2014; Weiss et al., 2008; Williams et al., 2020). The ingestion of a high-sugar beverage/meal …

Vascular Function in Women and Children Following a Pregnancy Complicated by Preeclampsia
… that preeclampsia is linked to later-life cardiovascular disease development in both mother and offspring. However, the mechanisms responsible for this phenomenon have not been determined, nor how they can be ameliorated. Non-invasive vascular assessment allows for the evaluation of subclinical …

Peripheral Vascular Function in Young Adults with Increased Risk of Cardiometabolic Disease
… suffer from peripheral vasculature dysfunction.</p> <p>Methods: Mean arterial pressure (MAP), Femoral (FBF) and Brachial Blood flow (BBF), Femoral (FVC) and Brachial Vascular Conductance (BVC), and Tissue Saturation Index (TSI) were assessed in twenty-four age (19 + 2.25 years), Sex …

Determining whether plasma levels of KATP channels are related to vascular function
… are ATP sensitive pores that are found in vascular smooth muscle cells and play an important role in regulating vascular function. They are also expressed in blood but their relationship with vascular function is unknown. This study aims to investigate the previously unknown relationship …

Role of kinins in mediating vascular function in healthy pregnancy and pre-eclampsia
… but evidence suggests that endothelial dysfunction is central to the development of the maternal syndrome. Kinins are endogenous peptides released by the endothelium that contribute to the regulation of cardiovascular homeostasis by inducing vasodilation, fibrinolysis and angiogenesis. …

The relation between sex, age and vascular function in the Framingham Heart Study
Endothelial dysfunction is a key modulator of the development of cardiovascular disease. Prior studies in selected samples have suggested that the association of age and vascular function may vary between men and women. To investigate the sex-specific patterns of this association, we utilized …

The acute effects of shear rate maniuplation on vascular function in a healthy population
Disease of the cardiovascular system is responsible for the majority of worldwide deaths. The progression of atherosclerosis is pertinent to increased risk of an acute coronary event. An understanding of all factors that contribute to the formation of atherosclerotic plaque is essential for future …

Modulation of the vascular function by cannabinoids, calcitonin gene related peptide and connexin hemichannels
… endothelial factors or factors released from perivascular nerves, thereby promoting vasodilation or vasoconstriction. Cannabinoids have been used for centuries for their psychoactive properties, but they have also a profound influence on the cardiovascular system, leading to vasodilation. …

Nutritional intake, systemic vascular function and clinical outcome in Bolivian highlanders with Chronic Mountain Sickness
… have identified that impaired systemic vascular endothelial function, subsequent to a free radical-mediated reduction in nitric oxide (NO) bioavailability [oxidative-nitrosative stress(OXNOS)], may contribute to the increased cardiovascular and potentially cerebrovascular risk. The …

Effect of a polyphenol-rich diet on vascular function and other markers of cardiovascular risk
… may have the potential to influence cardiovascular disease risk. However, there are very few polyphenol-specific dietary intervention studies, and none of sufficiently robust design that assess the effect polyphenol-rich foods on vascular function tests of known prognostic significance and …

Hyperpolarized Nuclei for NMR Imaging and Spectroscopy – Methodology and model studies of lung and vascular function
… gas. In this work, applications related to vascular imaging and lung function were investigated, using three hyperpolarized nuclei: 129Xe, 13C, and 3He. In addition, practical aspects regarding the handling and utilization of hyperpolarized substances were evaluated. The potential of …

Plasma nitrite reserve and vascular function before and after handgrip training in patients with heart failure
There is a direct relationship between vascular health and physical function. The controllers of this relationship are unclear, but appear to involve biomechanical and biochemical influences on the vascular wall. Purpose: The purpose of this dissertation was twofold: (1) to explore the relationship …
