Heat Shock Response Inhibition and Gene Expression in <em>Xenopus Laevis</em> Cultured Cells
(University of Waterloo, 2006)Various genes have evolved to protect the cell against stressor-induced damage or death including the heat shock proteins (HSPs). Stressor-induced HSP gene expression involves the activation of heat shock factor (HSF), ... -
Hepatic Proteome Analysis of Fathead Minnow (Pimephales promelas) Exposed to Municipal Wastewater in the Bow River
(University of Waterloo, 2019-09-27)Large quantities of contaminants enter Canadian waterways through municipal wastewater effluent (MWWE) each year. MWWE exposure can have a myriad of effects on aquatic organisms, including inducing chronic stress response ... -
Hepatic Steatosis and TNF-α Signaling
(University of Waterloo, 2007-04-24)The overall objective of this research was to investigate the status of tumor necrosis factor-α (TNF-α), and molecules associated with its signaling, in the pathological state of hepatic steatosis. The effect of NSAID ... -
Heralding Photonic Qubits for Quantum Communication
(University of Waterloo, 2016-01-22)Quantum communication attempts to harness the unique rules of quantum mechanics to perform communication tasks that are difficult or impossible using classical rules. To realize these benefits, information must be carried ... -
A Herschel/HIFI study of Water in Two Intermediate-Mass Star Forming Regions: Vela IRS 17 and Vela IRS 19
(University of Waterloo, 2013-05-27)While the single core accretion model for low mass star formation is well developed, it cannot simply be extended into the high mass star formation regime where clustered star formation dominates. The study of intermediate-mass ... -
Heterogeneous Particles with Isotropic Interactions: Investigating the Effect of Multiple Species and Particle Size Disparity on Self-Assembly
(University of Waterloo, 2015-10-21)There is much interest in using self-assembly to build materials at the microscopic level by using soft matter systems such as block copolymers and DNA coated colloids. Self-consistent field theory (SCFT) has seen much ... -
Heterostructure development and quantum control for semiconductor qubits
(University of Waterloo, 2022-01-04)States of confined electrons in semiconductors are promising candidates for quantum bits with high controllability, scalability, and coherence. Particularly, spin quantum dots offer direct integration with the modern MOS ... -
Heterothermy, body size, and locomotion as ecological predictors of migration in mammals
(Wiley, 2022-01)Migration is ubiquitous among animals and has evolved repeatedly and independently. Comparative studies of the evolutionary origins of migration in birds are widespread, but are lacking in mammals. Mammalian species have ... -
Hg2+ detection using a phosphorothioate RNA probe adsorbed on graphene oxide and a comparison with thymine-rich DNA
(Royal Society of Chemistry, 2016-06-21)Mercury is a highly toxic heavy metal and many DNA-based biosensors have been recently developed for Hg2+ detection in water. Among them, thymine-rich DNA is the most commonly used for designing Hg2+ sensors. However, the ... -
High Rate, Large Area Laser-assisted Chemical Vapor Deposition of Nickel from Nickel Carbonyl
(University of Waterloo, 2009-05-01)High-power diode lasers (HPDL) are being increasingly used in industrial applications. Deposition of nickel from nickel carbonyl (Ni(CO)4) precursor by laser-induced chemical vapor deposition (CVD) was studied with emphasis ... -
High Resolution Geophysical Characterization of a Gasoline Release into a Sand Column
(University of Waterloo, 2008-09-26)A controlled column experiment was conducted to investigate the geophysical response of gasoline spills into the partially saturated sand column. The column was 0.61 diameter (ID) and 2 m high cylindrical polyvinyl chloride, ... -
HIGH RESOLUTION MICROWAVE SPECTROSCOPY OF ULTRA COLD RYDBERG ATOMS AS A PROBE OF ELECTRIC AND MAGNETIC FIELDS
(University of Waterloo, 2003)In highly excited Rydberg atoms, the excited electron is in a large, loosely bound orbit. Hence, in contrast with the ground states, the Rydberg states are very sensitive to external electric field and can be ionized in ... -
High Resolution Packer Testing in Fractured Sedimentary Rock
(University of Waterloo, 2009-09-30)Packer tests in boreholes in fractured rock involving injection or withdrawal of water in borehole segments have been standard practice in bedrock hydraulic investigations pertaining to geotechnical and water resource ... -
High Throughput Analysis for On-site Sampling
(University of Waterloo, 2012-12-12)Until recently, multiple SPME fibres could not be automatically evaluated in a single sequence without manual intervention. This drawback had been a critical issue until recently, particularly during the analysis of numerous ... -
High Throughput Sequencing of MicroRNA in Rainbow Trout Plasma, Mucus, and Surrounding Water Following Acute Stress
(Frontiers, 2021-01-13)Circulating plasma microRNAs (miRNAs) are well established as biomarkers of several diseases in humans and have recently been used as indicators of environmental exposures in fish. However, the role of plasma miRNAs in ... -
High throughput solid phase microextraction: A new alternative for analysis of cellular lipidome?
(Elsevier, 2017-02-01)A new SPME method for untargeted lipidomic study of cell line cultures was proposed for the first time. In this study the feasibility to monitor changes in lipid profile after external stimuli was demonstrated and compared ... -
