Vaccines for finfish aquaculture: What do we need to know to make them work?
(Elsevier, 2012-08-08)Aquaculture still faces serious economic impacts due to the loss of animals to disease. A conservative estimate of 5% losses due to disease means that the finfish aquaculture industry loses over $1 billion annually on a ... -
Variation in fish fatty acid concentrations among lakes in the Dehcho region of the Northwest Territories
(University of Waterloo, 2020-12-22)Background: In the subarctic Dehcho region of the Northwest Territories, many remote communities rely on traditional foods, including fish, to supplement more expensive store-bought options. Fish are an excellent source ... -
Variations in Northern Dolly Varden (Salvelinus malma malma) total mercury concentrations from the northwestern Canadian Arctic
(University of Waterloo, 2014-10-22)Mercury (Hg) is a ubiquitous contaminant with harmful impacts on the aquatic ecosystem as well as human health. Studies to date of the bioaccumulative effects of Hg on northern fishes have focussed on all but one of the ... -
Vegetation Based Assessment of Wetland Condition in the Prairie Pothole Region
(University of Waterloo, 2018-01-22)The northern prairie pothole region (NPPR) in central and southern Alberta contains numerous shallow, open-water pothole wetlands that provide important ecosystem services to the region, such as flood mitigation. To address ... -
Vegetation diversity in mountain peatland systems
(University of Waterloo, 2021-01-14)Mountain valley bottom peatlands are poorly studied systems, particularly in Alberta, Canada, where the provincial inventory has neither mapped nor characterized them. Nonetheless, these ecosystems provide valuable ecosystem ... -
VER-155008 induced Hsp70 proteins expression in fish cell cultures while impeding replication of two RNA viruses
(Elsevier, 2019-02-01)The heat-shock protein 70 (Hsp70) inhibitor, VER-155008 (VER), was explored as a potential antiviral agent for two RNA viruses important to fish aquaculture, viral hemorrhagic septicemia virus (VHSV) and infectious pancreatic ... -
Wastewater to clinical case (WC) ratio of COVID-19 identifies insufficient clinical testing, onset of new variants of concern and population immunity in urban communities
(medRxiv, 2022-04-20)Clinical testing has been the cornerstone of public health monitoring and infection control efforts in communities throughout the COVID-19 pandemic. With the extant and anticipated reduction of clinical testing as the ... -
The water-sediment interactions for Hyalella azteca exposed to uranium-spiked or contaminated sediments and different overlying water chemistries
(University of Waterloo, 2009-07-07)In comparison with other metals such as Cd, Cu, Pb, Ni, and Zn, little is known about uranium (U) toxicity to Hyalella azteca. There is even no national U water or sediment quality guideline yet for the protection of aquatic ... -
Wetland birds and invasive plant management
(University of Waterloo, 2022-08-31)The Great Lakes coastal wetlands are some of the most diverse ecosystems in Ontario. However, their ecological integrity is continually threatened by development, nutrient pollution, and invasive species. Over the past two ... -
Wild fish responses to wastewater treatment plant upgrades in the Grand River, Ontario
(University of Waterloo, 2020-09-24)Municipal wastewater treatment plant (WWTP) effluent is a major point source of contaminants (nutrients, pharmaceuticals, estrogens, etc.) which can harm aquatic life. Many studies have investigated the effects of WWTP ... -
α-Dystroglycan is essential for the induction of Egr3, a transcription factor important in muscle spindle formation
(University of Waterloo, 2009-10-20)Muscle spindle fibers are specialized stretch receptors that allow the perception and coordination of limb movement. Differentiation of muscle spindles is initiated by signals derived from the in growing Ia sensory neurons ... -
β2-microglobulin distribution in trout body fluids and release from intestinal epithelial cells in response to plant meal components
(University of Waterloo, 2011-08-04)β2-microglobulin (β2m) exists free of the major histocompatibility complex class I (MHC I) receptor in many bodily fluids. The amount of protein present in these fluids has been found to be a useful prognostic marker for ... -
β‐Parvin Mediates Novel Integrin Signaling Pathways During Early Xenopus laevis Development.
(University of Waterloo, 2019-01-24)Crosstalk between cell adhesion molecules is critical for the cell rearrangements that occur during early Xenopus laevis development. Cells primarily use integrin receptors to adhere to and interpret the extracellular ...
