Understanding acute stress-mediated immunity in teleost fish
(Elsevier, 2021-12)The abilities and ways in which organisms respond to stress have long been demonstrated to affect the immune response of the organism. In mammalian studies, researchers have observed that chronic/long-term stress has a ... -
Understanding species life-history and ecology for improved conservation and recovery of the threatened Silver Shiner, Notropis photogenis
(University of Waterloo, 2022-06-03)Conservation and recovery strategies are typically developed with the best available information. However, for many imperilled small-bodied freshwater fish species there is often a lack of basic information available on ... -
Use of Fish Cell Cultures for the Study and Cultivation of Microsporidia
(University of Waterloo, 2011-08-26)Microsporidia are a group of obligate intracellular fungal parasites that infect a wide range of vertebrates and invertebrates, and are of economic and academic interest. Some areas of their economic impact are in aquaculture ... -
Use of fish cell lines to compare the cytotoxicity of Tetrabromobisphenol A with its degradation products and with an alternative brominated flame retardant
(University of Waterloo, 2011-08-22)Tetrabromobisphenol A, (TBBPA or Br4BPA), is a widely used brominated flame retardant (BFR). Although TBBPA and its breakdown products been found in river sediments, the environmental impact of their contamination is largely ... -
Use of Non-linear Models Based on Saturation Kinetics to Determine Chronic Co, Se or Zn Toxicity for Either Exposure or Body Burden in Hyalella azteca
(University of Waterloo, 2018-03-26)Water chemistry can influence the bioavailability, and therefore the toxicity, of metals and other elements. Water chemistry measurements have been incorporated into many water guidelines for the concentration of metals ... -
The use of plant growth promoting rhizobacteria to enhance phytoremediation of petroleum hydrocarbon-impacted soils
(University of Waterloo, 2011-09-30)Phytoremediation is a cost-effective and environmentally conscious technology that utilizes plants to remediate a variety of contaminants from the soil. Petroleum hydrocarbons (PHC), as a result of their widespread use are ... -
The Use of Plant Growth-Promoting Rhizobacteria (PGPR) and an Arbuscular Mycorrhizal Fungus (AMF) to Improve Plant Growth in Saline Soils for Phytoremediation
(University of Waterloo, 2008-01-18)Upstream oil and gas production has caused soil salinity problems across western Canada. In this work we investigated the use of ACC (1-aminocyclopropane-1-carboxylate) deaminase-producing plant growth-promoting rhizobacteria ... -
Use of prospective and retrospective risk assessment methods that simplify chemical mixtures associated with treated domestic wastewater discharges
(Wiley, 2018-03-01)A framework is presented that is intended to facilitate the evaluation of potential aquatic ecological risks resulting from discharges of down-the-drain chemicals. A scenario is presented using representatives of many of ... -
Use of rainbow trout cell lines to delineate the roles of p53 in fish and to evaluate the toxicity of emerging environmental contaminants, benzotriazoles and benzothiazoles
(University of Waterloo, 2015-05-01)Epithelial cell lines, RTgill-W1 and RTL-W1 from respectively the gill and liver of rainbow trout, Onchorhynchus mykiss (Walbum), were used to investigate the role of p53 in the cellular survival pathways of fish and to ... -
Use of Rainbow Trout Liver Cell Line (RTL-W1) to evaluate the toxicity of Heavy Fuel Oil 7102
(University of Waterloo, 2013-02-25)A rainbow trout liver cell line, RTL-W1, was used to evaluate the toxic potential of a heavy fuel oil (HFO) HFO 7102, and its fractions, which together with the HFO are referred to as the oil samples. The fractions were ... -
Use of Water Isotope Tracers to Characterize the Hydrology of Prairie Wetlands in Alberta
(University of Waterloo, 2018-01-22)Our understanding of prairie wetland hydrology comes primarily from a handful of long-term research stations, but generalizing from a few intensively monitored areas to the entire prairie pothole region requires assumptions ... -
Use of water isotope tracers to elucidate hydrological conditions of lakes in the Peace-Athabasca Delta over space and time: A foundation for lake ecosystem monitoring
(University of Waterloo, 2022-01-17)Hydrological monitoring in complex, dynamic northern floodplain landscapes is challenging but increasingly important as these ecosystems come under threat from multiple stressors, including climate-driven decline in ... -
Using cell lines to study factors affecting transmission of fish viruses
(University of Waterloo, 2014-01-02)Factors that can influence the transmission of aquatic viruses in fish production facilities and natural environment are the immune defense of host species, the ability of viruses to infect host cells, and the environmental ... -
Using Chemical Crosslinking and Mass Spectrometry for Protein Model Validation and Fold Recognition
(University of Waterloo, 2006)The 3D structures of proteins may provide important clues to their functions and roles in complex biological pathways. Traditional methods such as X-ray crystallography and NMR are not feasible for all proteins, while ... -
Using Folsomia candida to Test the Toxicity of Weathered Petroleum-impacted Field Soils before and after Phytoremediation
(University of Waterloo, 2014-05-01)The Canadian Council of Ministers of the Environment (CCME) developed guidelines for petroleum hydrocarbon (PHC) impacted field soils based on the “worst case” scenario of a fresh petroleum spill (CCME, 2001b; CCME, 2008b). ... -
