Identification and characterization of toxic cyanobacteria in two forested maritime watersheds in North America
(University of Waterloo, 2021-06-01)Healthy forested watersheds naturally provide high quality drinking water to communities. However, the integrity and quality of these water sources may be threatened by climate change-exacerbated disturbances such as ... -
Identification of genes regulated by the Drosophila transcription factor Hindsight
(University of Waterloo, 2013-05-24)Hindsight (HNT) is a zinc finger transcription factor that is required for morphogenesis of the Drosophila embryo, having roles in germ band retraction (GBR) as well as dorsal closure (DC). HNT expression is also found in ... -
Identification of MH Class IIβ alleles conferring resistance/susceptibility to Flavobacterium psychrophilum in Oncorhynchus mykiss families
(University of Waterloo, 2014-12-11)Flavobacterium psychrophilum is the causative agent of bacterial cold water disease (BCWD), which is a major concern for aquaculture and fish health, with mortality rates of 20-30%. Without a commercially approved vaccine, ... -
Identification of Oil Sands Naphthenic Acid Structures and Their Associated Toxicity to Pimephales promelas and Oryzias latipes
(University of Waterloo, 2013-01-25)The oil sands, located in north-eastern Alberta, are one of the largest deposits of oil worldwide. Because the Alberta Environmental Protection and Enhancement Act prohibits the release of oil sands process-affected material ... -
Impact of Cadmium On The Hypothalamus-Pituitary-Interrenal Axis Function in Rainbow Trout
(University of Waterloo, 2013-04-30)Cadmium (Cd) is a nonessential metal present in sublethal concentrations within the aquatic environment. Cd is an endocrine disruptor and high concentrations of this metal suppress stressor-induced cortisol production in ... -
Impact of non-steroidal anti-inflammatory drugs on the adaptive responses to stress in rainbow trout
(University of Waterloo, 2007-06-19)Pharmaceutical drugs are used extensively by humans and domestic animals. The detection of compounds such as non-steroidal anti-inflammatory drugs (NSAIDs) in effluents of sewage treatment plants and surface waters has ... -
Impact of sex and pathophysiology on optimal drug choice in hypertensive rats: Quantitative insights for precision medicine
(Elsevier, 2021-04)Less than half of all hypertensive patients receiving treatment are successful in normalizing their blood pressure. Despite the complexity and heterogeneity of hypertension, the current antihypertensive guidelines are not ... -
Impact of the antidepressant venlafaxine on the hypothalamus-pituitary-interrenal axis function in rainbow trout
(University of Waterloo, 2014-05-27)Over the recent years, venlafaxine has become the predominant antidepressant drug detected in municipal wastewater effluents (MWWE) and aquatic systems. However, very little is known about the effect of this drug in the ... -
Impact of water activity on microbial growth in bentonite clay
(University of Waterloo, 2023-08-11)Canada is in the process of designing and implementing a deep geological repository (DGR) for long-term storage of used nuclear fuel. This proposed storage structure will be a multi-barrier system placed 500-800 metres ... -
Impacts of acute and anthropogenic stress on fish microRNA
(University of Waterloo, 2021-12-21)Fishes play crucial roles in the ecology of aquatic environments and contribute to the multi-billion-dollar fisheries industry. The integrity of their populations and health needs to be maintained for future generations ... -
Impacts of Low Temperature on the Teleost Immune System
(Multidisciplinary Digital Publishing Institute, 2017-11-22)As poikilothermic vertebrates, fish can experience changes in water temperature, and hence body temperature, as a result of seasonal changes, migration, or efflux of large quantities of effluent into a body of water. ... -
Impacts of Mixtures of Copper and 1,2-dihydroxyanthraquinone on Physiology and Gene Expression in Lemna gibba L.G-3
(University of Waterloo, 2008-08-21)Polycyclic aromatic hydrocarbons (PAHs) and metals are co-contaminants of aquatic environments near industrial and urbanized areas. Mixtures could result in synergistic toxicity impairing macrophyte growth and potentially ... -
Impacts of temperature on Asian Carp life history and population growth
(University of Waterloo, 2021-12-21)Asian carp (bighead carp, Hypophthalmichthys nobilis; black carp, Mylopharyngodon piceus; grass carp, Ctenopharyngodon idella; and silver carp, H. molitrix) are a group of invasive species predicted to cause ecological and ... -
Impacts of wastewater treatment plant effluent and pharmaceutical exposure on innate cytokine expression of darters (Etheostoma spp.) in the Grand River
(University of Waterloo, 2022-08-10)Aquatic organisms, such as fish, are in constant contact with various stressors and antigenic material present within their environments. The impact of stressors associated with wastewater-exposed environments on native ... -
Impacts of wastewater treatment plant effluent on energetics and stress response of rainbow darter (Etheostoma caeruleum) in the Grand River watershed
(Elsevier, 2018-10)The objective of this study was to assess the effects of municipal wastewater treatment plant effluent on the energetics and stress response of rainbow darter (Etheostoma caeruleum). Male and female rainbow darter were ... -
