Omega-3 polyunsaturated fatty acids (n-3 PUFA) enriched eggs are an increasingly important contributor to the egg industry due to the health benefits of n-3 PUFA. During storage and cooking, n-3 PUFA could undergo oxidation and further cause cholesterol oxidation. This study examined stability of...

Glomus cells of the carotid body are peripheral chemoreceptors that detect changes in arterial oxygen levels. Hypoxia suppresses oxygen-sensitive K+ channels in glomus cells, resulting in cytosolic Ca2+ ([Ca2+]i) elevation in glomus cells via the activation of voltage-gated Ca2+ channels. The...

I investigated, water, invertebrates and fishes from lakes in Banff National Park and Kananaskis Country, Alberta for selenium (Se), an element known to be toxic to vertebrates. At some depths, Se concentrations in sediment exceeded recognized thresholds for bird and fish reproductive...

The first chapter of this thesis describes the development of a general route for the generation of selenium stabilized carbanions via a method that bypasses acid catalyzed formation of selenoacetals. Aldehydes are first converted into α-hydroxystannanes by nucleophilic addition of Bu3SnLi. The...

Arsenic is a potent environmental contaminant and human carcinogen, occurring naturally in the earth’s crust and entering the food chain through leeching into the water supply. Upon entering the body, inorganic arsenic is methylated to mono- and di-methylated forms, the trivalent versions of...

Unique cellular interactions between the obligate intracellular bacteria Wolbachia pipientis and its insect host
DownloadFall 2011
Wolbachia are maternally inherited obligate intracellular bacteria found in arthropods, where they induce feminization, male-killing, parthenogenesis, and cytoplasmic incompatibility (CI). CI is conditional male sterility, in which Wolbachia-infected males successfully mate with infected females,...

Water-Dispersible Magnetic Particle-Graphene Oxide Composites: Synthesis, Characterization and Application in the Removal of Selenium Oxyanions
DownloadSpring 2014
Selenium is toxic in excess with a high mobility in water. Existing adsorbents only show some removal capacity for selenite but perform poorly (typical removal percentage < 50 %) for selenate, the more bioavailable and soluble species. In this thesis, two Magnetic particle-Graphene Oxide...
