Cardiovascular Outcomes Following Xenobiotic Pulmonary Exposures
… the synergistic relationship between PM exposures and CVD is crucial. As a result, investigations of PM-induced mechanisms of toxicity have grown in kind. Despite this effort the putative mechanisms that underlie CVD and exposure to PM remain elusive. We set out to explore the potential …

Stability of Field Emitter Arrays to Oxygen Exposures
… molybdenum based field emitter arrays to oxygen exposures and to improve the overall reliability. In addition, we also evaluated the emission current stability of gold-coated field emitter arrays to oxygen exposures. oxygen at 1x10-6 torr was introduced into the chamber through a leak valve for …

Aetiological role of early lifestyle exposures in puberty timing
Amidst the global secular trends towards earlier timing of pubertal development, there are abundant evidence from various populations that early puberty timing is associated with higher risks for a wide range of subsequent adverse physical and mental health outcomes. Despite the increasing …

Lucky exposures: diffraction limited astronomical imaging through the atmosphere
… reference stars used for our method (the Lucky Exposures technique) can generally be fainter than those required for the natural guide star adaptive optics approach or those required for other speckle imaging techniques. The low complexity and low instrumentation costs associated with the Lucky …

Yeast-based impedance biodosimetry for retrospective assessment of radiation exposures
… dosimeters for retrospective assessments of exposures following radiological accidents using impedance biodosimetry. The radiation response of S. cerevisiae was examined by using cellular metabolic activity and impedance as a means to evaluate dose. A novel dosimeter design was developed to …

Indoor biological exposures : what can HVAC filter dust tell us?
… the potential health impacts of biological exposures that occur in the home is crucial. Recently, rapid advances in high-throughput DNA sequencing technology have spurred increased study of the relationships between the human and built environment microbiomes. HVAC filters hold promise as …

Characterizing Lung Inflammation in Agricultural Respiratory Exposures Between the Sexes
… to reveal the impact to the lungs of such exposures. Overall, we observed that female mice, exposed to an agriculturally relevant concentration combining LPS plus glyphosate for 5 days, exhibited respiratory inflammatory effects significantly different compared to each single exposure. …

Investigating the impact of pharmacological exposures on the developing epigenome
… following environmental or pharmacological exposures. In this thesis, I characterise the impact of pharmacological exposures on imprinted gene regulation in vitro. 5-azacytidine (AZA) and decitabine (DAC) are both cytidine nucleoside analogues used in the treatment of acute myeloid …

Chemical exposures in drinking water: contaminant analysis and physicochemical behavior
Environmental chemical exposures pose an understudied risk to human health. The quality and accessibility of data on occurrence in the environment and physicochemical behavior of industrial chemicals are integral for accurate exposure risk assessment. In this dissertation, analytical chemistry …

Cellular Reprogramming in Skeletal Muscle after Repeated Exposures to Endotoxin
Obesity-related metabolic derangements have been linked to toll-like receptor 4 (TLR4), an innate immune system receptor, due to its role in proinflammatory pathways. Lipopolysaccharide (LPS), a gram-negative bacteria cell wall component, is the ligand for TLR4, and has been shown to be elevated in …

Trauma Exposures Across the Life Course for Individuals Who Experience Incarceration
… exist, however, documenting the types of trauma exposures and the developmental timing of the trauma exposures experienced by incarcerated individuals, especially men, as most trauma research to date has focused on incarcerated women. In order to develop appropriate interventions that increase …

Health hazards and cancer in relation to occupational exposures among Swedish seafarers
… to asbestos were up to 5 fibre-years. Other exposures were carcinogenic PAHs and nitroarenes. A web-based survey to active seafarers in the Swedish merchant fleet revealed noise, the risk of accidents, whole-body vibrations and ergonomic strain as main work environment problems. General …
