A Retrospective Analysis of the Safety and Efficacy of a 6-Week Pulmonary Rehabilitation Program in Patients with Severe Pulmonary Arterial Hypertension
DownloadSpring 2014
Pulmonary Arterial Hypertension (PAH) is progressive disease characterized by reduced exercise capacity and decreased quality of life. Despite the availability of disease targeted therapies outcomes remain sub-optimal. Pulmonary Rehabilitation has proven to improve outcomes in other chronic...

Are Sex and Estrogen Modulators of Sympathetic Vascular Control in Resting and Contracting Skeletal Muscle?
DownloadSpring 2018
The purpose of this thesis was to investigate whether sex and estrogen modulate sympathetic neurovascular control in resting and contracting skeletal muscle. This thesis also investigated the hypothesis that the effects of sex and estrogen on neurovascular control would be mediated by the signal...

Spring 2012
Human cytomegalovirus (HCMV) is implicated in several vascular diseases through endothelial dysfunction. Most of the research on CMV has focused on either congenital CMV infections or CMV disease in immunocompromised hosts; however, CMV has also been associated with vascular diseases in...

Effect of dietary nitrate on sympathetic vasoconstriction in resting and contracting skeletal muscle
DownloadFall 2015
Dietary nitrate (NO3-) may increase nitric oxide (NO) bioavailability and alter the control of blood flow at rest and during exercise. This thesis investigated the effect of dietary NO3- supplementation on sympathetic mediated control of skeletal muscle blood flow in resting and contracting...

Fall 2022
Contraction-mediated inhibition of sympathetic vasoconstriction (sympatholysis) is enhanced in female compared with male rats. Acute pharmacological blockade of nitric oxide (NO) production abolished the sex difference in sympatholysis, indicating that NO-mediated sympatholysis is elevated in...

Skeletal Muscle Sympathetic Vasoconstrictor Control Following Short-Term Mild- and Heavy-Intensity Exercise Training
DownloadFall 2013
The purpose of this thesis was to investigate the effects of short-term endurance exercise training (ET) on sympathetic vasoconstriction in resting and contracting skeletal muscle. To achieve these aims, rats were exercise trained on a motorized treadmill and an anesthetised whole animal in situ...

The effect of aerobic fitness on the cardiovascular and sympathetic nervous system response to physiological stress at rest and during dynamic exercise
DownloadFall 2012
A cardio-protective adaptation associated with aerobic fitness may be an attenuated sympathetic nervous system (SNS) and cardiovascular response to stress. The hypothesis that the cardiovascular and SNS responses to physiological stress at rest and during exercise would be a function of...

The effect of eight weeks of home based aerobic exercise training on peak exercise oxygen consumption, six-minute walk test distance, thigh muscle mass, and health related quality of life in Child Pugh class A and B cirrhosis patients
DownloadFall 2017
Purpose: Cirrhosis patients have reduced peak aerobic power (peak VO2) that is associated with reduced survival. Supervised endurance training is an effective therapy to increase exercise tolerance in cirrhosis. The effect of home-based endurance exercise training (HET) on improving peak VO2 in...

Spring 2022
Background: Carbon monoxide alters cardiovascular function through its actions as a signaling molecule and by limiting oxygen delivery in the blood, favouring pro-dilatory and anti-constrictor effects within the vasculature. The impacts of mild carbon monoxide exposure on vascular responses to...

Βeta-adrenergic receptors and opposition of evoked sympathetic vasoconstriction: Effects of sex and exercise training
DownloadFall 2016
Stimulation of the sympathetic nervous system evokes the release of neurotransmitters and produces vasoconstriction that is primarily mediated by the binding of norepinephrine (NE) to alpha-adrenergic receptors. However, NE may also bind to beta (β)-adrenergic receptors and produce vasodilation...
