The characterization of γH2AX and p53 as biomarkers of genotoxic stress in a rainbow trout (Oncorhynchus mykiss) brain cell line
(Elsevier, 2018-06-01)Rainbow trout cell cultures were exposed to three genotoxicants and examined for effects on γH2AX and p53 levels by western blotting and on cell viability using the indicator dyes Alamar Blue (AB) for energy metabolism and ... -
The characterization of γH2AX as a biomarker of genotoxicity in Oncorhynchus mykiss
(University of Waterloo, 2017-05-19)Environmental contamination due to by-products and waste from industrial activities is a growing universal concern, especially regarding the impact on water and the aquaculture industry. Conventional tests to diagnose ... -
Characterization on PAR-3 in early Xenopus laevis development
(University of Waterloo, 2013-01-24)Polarized cell movements are essential to the cell rearrangements that occur during morphogenesis. In Xenopus, cell polarity is reflected in the directional cell intercalations that drive the morphogenetic movements ... -
Characterization, Quantification and Modification of Starch Nanoparticles
(University of Waterloo, 2014-09-22)Natural polymers, such as polysaccharides, have the potential to replace petroleum-based polymers in certain industrial applications. Ecosphere® starch nanoparticles (ENPs), produced by EcoSynthetix Inc., are starch-based ... -
Characterization, Verification and Control for Large Quantum Systems
(University of Waterloo, 2015-03-31)Quantum information processing offers potential improvements to a wide range of computing endevaors, including cryptography, chemistry simulations and machine learning. The development of practical quantum information ... -
Characterizing a role for α-parvin in Xenopus laevis Development
(University of Waterloo, 2021-09-20)In metazoans dynamic regulation of cell adhesion is critical for the cell movements that characterize gastrulation. It is clear that the adhesive property of cells is modulated in a highly coordinated spatial and temporal ... -
Characterizing and Modelling Tailings Hydrogeochemistry Under a Composite Cover at the Abandoned Kam Kotia Mine, ON
(University of Waterloo, 2023-01-09)A principal environmental concern associated with mining is the weathering of mine waste in the presence of oxygen and water that generates acid mine drainage (AMD) concentrated in toxic elements. Installation of composite ... -
Characterizing Aspects of Groundwater Flow in Discontinuous Permafrost Terrain, Within the Central Mackenzie Valley, NWT
(University of Waterloo, 2021-05-26)With recent developments in oil and gas exploration technologies that have opened regions of Canada’s northern territories and the threat of climate change, uncertainties around how these factors may impact the environment ... -
Characterizing Changes in Dipeptidyl Peptidase IV/CD26 on Colon Carcinoma Cells in Response to Prostaglandin Treatment
(University of Waterloo, 2018-08-01)Dipeptidyl peptidase IV (DPPIV) – also known as CD26 – is a multifunctional transmembrane protease found on the surface of most human cells, and shows variable expression between different types of cancer. DPPIV activity ... -
Characterizing Chromium Isotope Fractionation During Reduction of Cr(VI): Batch and Column Experiments
(University of Waterloo, 2012-02-22)Chromium (VI) is a pervasive groundwater contaminant that poses a considerable threat to human health. Remediation techniques have focused on the reduction of the highly mobile Cr(VI) to the sparingly soluble, and less ... -
Characterizing current and past hydroecological conditions in shallow tundra ponds of the Hudson Bay Lowlands
(University of Waterloo, 2012-01-10)Due to accelerated climatic warming during the past fifty years, interest and concerns have been growing about changes in the ecological integrity of shallow freshwater ponds that dominate the landscape of the Hudson Bay ... -
Characterizing Errors in Quantum Information Processors
(University of Waterloo, 2016-05-12)Error-free computation is an unattainable ideal, yet our world now contains many computers that appear error-free to their users. That such things are possible is explained by sophisticated theorems that demonstrate the ... -
Characterizing Humulone Content in Beer Using Differential Mobility Spectrometry
(University of Waterloo, 2018-09-19)Beer is a complex fermented beverage and several hundreds of components have been identified erenow. Hops are extremely important to beer’s organoleptic qualities, especially bitterness. Bitterness, a distinguishing component ... -
