An Obese Genotype Affects Apoptosis Related Gene Expression
(University of Waterloo, 2009-01-15)Apoptosis is a genetically regulated form of cell death that occurs when the cell is exposed to physiological, pathogenic, or cytotoxic stimuli. Unregulated apoptosis (too much or too little apoptosis) at any time from ... -
An Obese Genotype Affects the Sphingolipid Signaling Pathway
(University of Waterloo, 2008-01-24)Sphingolipids are important signaling molecules regulating cell growth, cell death and differentiation, thus making them important molecules in determining the fate of a cell and in the pathogenesis of chronic illnesses. ... -
Obesity associated colon tumorigenesis: An assessment of tumor phenotype
(University of Waterloo, 2006)Colon cancer and obesity are two significant and related pathological states with multiple etiological factors. In this dissertation, it was hypothesized that tumor growth is accelerated in the altered state of obesity ... -
Objective assessment of Visual acuity in infants
(University of Waterloo, 2013-08-06)Purpose Early detection of abnormal visual acuity (VA) is crucial in the identification and management of ocular and visual abnormalities in infants. Currently, the Teller Acuity Cards (TACs) are considered the gold ... -
Observation of Resonant Electric Dipole-Dipole Interactions Between Cold Rydberg Atoms Using Microwave Spectroscopy
(University of Waterloo, 2006)This thesis reports the first observation of the resonant electric dipole-dipole interaction between cold Rydberg atoms using microwave spectroscopy, the observation of the magnetic field suppression of resonant interactions, ... -
Observations of Atmospheric Gases Using Fourier Transform Spectrometers
(University of Waterloo, 2007-10-23)Remote sensing of atmospheric gases improves our understanding of the state and evolution of the Earth’s environment. At the beginning of the thesis, the basic principles for the retrieval of concentrations of atmospheric ... -
The Occurrence and Behavior of Rainfall-Triggered Landslides in Coastal British Columbia
(University of Waterloo, 2009-06-19)This thesis seeks to analyze the occurrence and behavior of rainfall-triggered landslides in coastal British Columbia. In particular, it focuses on the analysis of landslide temporal and spatial distributions occurrence ... -
Occurrence and Seasonal Variability of Selected Pharmaceuticals in Southern Ontario Drinking Water Supplies
(University of Waterloo, 2007-04-27)The presence and seasonal variability of human and veterinary pharmaceuticals in surface water (raw water) and treated water samples from two drinking water facilities in Southern Ontario was investigated. Water samples ... -
Occurrence, Fate, and Mobility of Antibiotic Resistant Bacteria and Antibiotic Resistance Genes among Microbial Communities Exposed to Alternative Wastewater Treatment Systems
(University of Waterloo, 2012-08-29)The ubiquitous nature of antibiotic resistance and antibiotic resistance genes (ARGs) among environmental pathogens from a variety of wastewater effluents, suggests that the aquatic environment, and specifically alternative ... -
Octupolar Ordering in the b>0 Bilinear-Biquadratic Heisenberg Pyrochlore
(University of Waterloo, 2019-01-25)We investigate the bilinear-biquadratic Heisenberg model on the pyrochlore lattice. While negative biquadratic couplings result in a first-order transition into a nematic ordered state with spins aligned mutually ... -
Ocular Discomfort Upon Tear Drying
(University of Waterloo, 2003)<b>Purpose:</b> Assess the relationship between tear film drying and sensation between blinks. <b>Methods:</b> MATLAB sampled a slitlamp video camera, a potentiometer and a microphone while subjects kept one eye open ... -
Ocular impression-taking - which material is best?
(Wolters Kluwer, 2019-01)Objectives: To assess the efficacy and effect on clinical signs of a polyvinylsiloxane (Tresident; Shütz Dental Group GmbH, Germany) compared with an irreversible hydrocolloid (Orthoprint; Zhermack SpA, Badia Polesine, ... -
Ocular Perfusion Pressure in Spaceflight-Associated Neuro-Ocular Syndrome
(University of Waterloo, 2020-10-26)Purpose: Spaceflight associated neuro-ocular syndrome (SANS) is considered by the National Aeronautics and Space Administration (NASA) as one of the most significant barriers to long term space exploration (Larkin, 2018). ... -
Ocular Surface Sensory Processing and Signal Detection Theory
(University of Waterloo, 2021-09-28)Purpose: The main aim of the experiments in this thesis is to evaluate the feasibility of using signal detection theory (SDT) to determine the detectability and bias of various ocular surface pneumatic stimuli. Chapter ... -
OEP15-1 and OEP7.3 Localize to the Outer Envelope of Chloroplasts Using a Novel and Uncharacterized Targeting Pathway
(University of Waterloo, 2021-09-27)Chloroplasts originated from an endosymbiotic event where a Gram-negative cyanobacterium was engulfed by an ancestral eukaryotic cell. The genome of the endosymbiont has since gone through extensive gene transfer to the ... -
An off-lattice derivation and thermodynamic consistency consideration for the Sanchez-Lacombe equation of state
(University of Waterloo, 2017-11-09)The application of the Sanchez-Lacombe equation of state (SL-EOS) to homogeneous polymeric mixtures is requisite for the application of some types of Self-Consistent Field Theory (SCFT) to inhomogeneous mixtures. It has ... -
An Off-Lattice Model of the Sanchez-Lacombe Equation of State for Polymers with Finite Flexibility
(University of Waterloo, 2020-05-19)An extension to the off-lattice Sanchez Lacombe equation of state is proposed by including internal degrees of freedom to account for the finite flexibility of polymer molecules. The extension allows polymer molecules to ... -
Oligomerization and hemolytic properties of the C-terminal domain of pyolysin, a cholesterol-dependent cytolysin
(NRC Research Press, 2013-04)Pyolysin (PLO) belongs to the homologous family of the cholesterol-dependent cytolysins (CDCs), which bind to cell membranes containing cholesterol to form oligomeric pores of large size. The CDC monomer structure consists ... -
