Effect of combined sodium arsenite and cadmium chloride treatment on heat shock protein gene expression in Xenopus laevis A6 kidney epithelial cells
(University of Waterloo, 2013-09-26)Sodium arsenite and cadmium chloride are two widespread environmental toxicants which have deleterious effects on living organisms. At the cellular level, sodium arsenite and cadmium chloride cause oxidative stress, ... -
Effect of composting and amendment with biochar and woodchips on the fate and leachability of pharmaceuticals in biosolids destined for land application
(Elsevier, 2022-03)Land application of biosolids can improve soil fertility and enhance crop production. However, the occurrence and persistence of pharmaceutical compounds in the biosolids may result in leaching of these contaminants to ... -
Effect of Dissipation on the Dynamics of Superconducting Single Electron Transistors
(University of Waterloo, 2012-08-30)In this thesis, I will present the experimental results of the dynamics of superconducting single electron transistors (sSETs), under the influence of tunable dissipation. The sSET, consisting of two dc SQUIDs in series ... -
Effect of ethanol on BTEX biodegradation in aerobic aquifer systems
(University of Waterloo, 2008-01-04)Ethanol can affect the biodegradation of gasoline hydrocarbons in groundwater. High concentrations of ethanol can be toxic to subsurface microorganisms that are otherwise capable of degrading hydrocarbons, such as benzene, ... -
The Effect of Freezing on the Elution of PVA from Contact Lenses
(University of Waterloo, 2024-04-30)Contact lenses are widely used, with over 140 million wearers globally. Wearing contact lenses can cause symptoms of discomfort and dryness, which affect nearly half of all wearers. To address this concern, this thesis ... -
Effect of Fuel Ethanol on Subsurface Microorganisms and its Influence on Biodegradation of BTEX Compounds.
(University of Waterloo, 2000)Ethanol is used as fuel in neat form in some countries (Brazil and India) or blended with gasoline (Europe, Canada and the United States). The benefits of ethanol use include octane enhancement, a cleaner environment and ... -
Effect of Gemini Surfactants on Amyloid Beta Aggregation
(University of Waterloo, 2013-09-27)Alzheimer’s disease (AD) is a progressive dementia affecting cognition, behavior, and functional status and there is no cure which exists for it. In AD, Amyloid Beta (Aβ) peptides form aggregates that are neurotoxic in the ... -
The effect of glyphosate on bacteria and archaea community composition in freshwater biofilms
(University of Waterloo, 2022-04-04)Glyphosate-based herbicides are some of the most widely used herbicides in the world today, however, there is still much to learn about how glyphosate affects non-target ecosystems. Specifically, freshwater aquatic biofilms ... -
Effect of H2 Pressure on Hydrogen Absorption and Granular Iron Corrosion Rates
(University of Waterloo, 2014-01-08)Hydrogen gas production occurs in permeable reactive iron barriers (PRBs) due to the anaerobic corrosion of granular iron. Once produced, this hydrogen gas can have detrimental physical effects on PRB performance. ... -
Effect of heat shock factor inhibitor, KNK437, on stress-induced hsp30 gene expression in Xenopus laevis A6 cells
(University of Waterloo, 2008-05-01)Prokaryotic and eukaryotic organisms respond to various stresses with the production of heat shock proteins (HSPs). HSPs are molecular chaperones that bind to unfolded proteins and inhibit their aggregation as well as ... -
The effect of hematocrit on solid-phase microextraction
(Elsevier, 2018-02-25)Solid-phase microextraction (SPME) is an approach to sample preparation that has demonstrated its appropriateness for isolating/enriching analytes present in complex biofluids with minimum sample pre-treatment. Several ... -
Effect of hemin and baicalein on heme oxygenase-1 accumulation and function in Xenopus laevis cultured cells
(University of Waterloo, 2018-04-26)Heme oxygenase-1 (HO-1) is a stress-inducible enzyme that catalyzes the rate-limiting step in the hemin degradation pathway. Studies in mammalian systems determined that HO-1 promoted cell survival by reducing oxidative ... -
Effect of hemin, baicalein and heme oxygenase-1 (HO-1) enzyme activity inhibitors on Cd-induced accumulation of HO-1, HSPs and aggresome-like structures in Xenopus kidney epithelial cells
(Elsevier, 2018-08-01)Cadmium is a highly toxic environmental pollutant that can cause many adverse effects including cancer, neurological disease and kidney damage. Aquatic amphibians are particularly susceptible to this toxicant as it was ... -
Effect of heterophoria type and myopia on accommodative and vergence responses during sustained near activity in children
(Elsevier, 2012-03-15)The influence of phoria-type and myopia on changes to vergence and accommodation during prolonged near-task was examined in 53 children. Participants were classified into phoria and refractive categories based on near ... -
