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...

Assessing the relationships between weather, food limitation and breeding ecology in an Arctic top predator
DownloadSpring 2016
A long term project being conducted on a population of Peregrine Falcons (Falco peregrinus) breeding near Rankin Inlet, Nunavut, Canada, has chronicled a steady decline in annual productivity over 30 years. By documenting the direct effects of summer rainfall on nestling mortality, a recent study...

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...

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...

The prevalence and determinants of adequate vitamin D intake and supplementation among Canadian children
DownloadFall 2016
Most Canadian children are not meeting the dietary recommendations for vitamin D and have not enough sun exposure to synthesize vitamin D in their skin. Vitamin D supplementation therefore seems a necessity. However, no study has examined whether vitamin D from diet and supplements combined is...

Understanding the role of Clostridioides difficile and Vitamin D supplementation in shaping the gut microbiome of Canadian infants
DownloadSpring 2019
Introduction: The gut microbiome is shaped during infancy and has an important role in the development of both the immune and metabolic systems. Many early life exposures and events contribute to the composition of this complex intestinal environment, notably early infant diet and breastfeeding....

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...
