Examination of curcumin-induced heat shock protein gene expression in Xenopus laevis A6 kidney epithelial cells
(University of Waterloo, 2010-08-11)The heat shock response is a cellular homeostatic mechanism that is activated in response to stressful stimuli (e.g. heat shock, heavy metals, disease states etc.), which causes an increase in unfolded protein, which ... -
Examination of sodium arsenite- and cadmium chloride-induced HSP accumulation and inhibition of proteasome activity in Xenopus laevis A6 kidney epithelial cells
(University of Waterloo, 2011-09-28)Sodium arsenite (NA) and cadmium chloride (CdCl2) are two relatively abundant environmental toxicants that have numerous detrimental effects on living organisms. At the cellular level, NA and CdCl2 produce reactive oxygen ... -
Examination of the effect of the natural plant extract, withaferin A, on heat shock protein gene expression in Xenopus laevis A6 cells
(University of Waterloo, 2010-09-03)In eukaryotes, the ubiquitin-proteasome system (UPS) degrades most cellular protein. Inhibition of the UPS has been associated with different disease states and can affect various intracellular processes including the ... -
Examination of the expression of the heat shock protein gene, hsp110, in Xenopus laevis cultured cells and embryos
(University of Waterloo, 2008-01-16)Prokaryotic and eukaryotic organisms respond to various stressors with the production of heat shock proteins (HSPs). HSP110 is a large molecular mass HSP that is constitutively expressed in most adult mammalian tissues. ... -
Examining Cell Movements in the Neurulating Chick Embryo
(University of Waterloo, 2008-01-24)The avian embryo is a popular animal model because it is widely available (Antin et al., 2004), it is easily manipulated, and it can provide important insights into normal and abnormal embryo development (Kulesa, 2004). ... -
Examining Hydrogeological Processes in Freezing Soils using Remote Geophysical and Numerical Techniques
(University of Waterloo, 2019-02-11)The work presented in this thesis aimed to demonstrate the use of remote geophysical methods and numerical modelling to address questions related to hydrogeological processes in freezing soils. Two different study areas ... -
Examining oil sands dissolved carbon and microbial degradation using stable isotope analysis
(University of Waterloo, 2007-05-22)Oil sands mining operations in northeastern Alberta are rapidly expanding. Upgrading and extracting the bitumen from the sand requires large volumes of water generating large quantities of oil sands process water/materials ... -
Examining the growth and stable isotopes of phytoplankton and periphyton communities exposed to oil sands reclamation strategies
(University of Waterloo, 2013-01-28)The impacts of oil sands processed materials (OSPM) on phytoplankton and periphyton community growth and stable carbon and nitrogen isotopes were examined. Estimates of plankton and periphyton community growth, measured ... -
Examining the taxonomic identity of the green alga Oophila amblystomatis (Chlamydomonadales), the biogeography of its symbiont Ambystoma maculatum (Amphibia), and the response of the green alga to two herbicides
(University of Waterloo, 2016-09-02)The yellow spotted salamander (Ambystoma maculatum) shares a unique endosymbiotic relationship with the unicellular green alga Oophila amblystomatis. Though a number of studies have isolated and identified O. amblystomatis, ... -
Exercise-Induced Fatigue and Caffeine Supplementation Affect Psychomotor Performance but Not Covert Visuo-Spatial Attention
(Public Library of Science, 2016-10-21)Fatigue resulting from strenuous exercise can impair cognition and oculomotor control. These impairments can be prevented by administering psychostimulants such as caffeine. This study used two experiments to explore the ... -
Exodermal Function and Suberin Chemistry
(University of Waterloo, 2010-05-18)The thesis work concerns the multiseriate exodermis (MEX), an outermost cortical layer (two or more cell layers thick) characterized by Casparian bands and suberin lamellae. Diverse aspects of Iris germanica's MEX were ... -
Exotic Circuits for Enhanced Quantum Algorithms and Computation
(University of Waterloo, 2023-08-09)Quantum circuits play an essential role in many disciplines of quantum information science. They can not only be represented in the traditional gate-based paradigm, but also an alternative measurement-based paradigm. The ... -
