Plankton Metabolic Balance and its Controlling Factors in the Coastal Zone of the Laurentian Great Lakes
(University of Waterloo, 2007-10-01)Plankton metabolic balance (PMBm) of the surface mixed layer was calculated as the ratio of areal rates of gross photosynthesis (AGP) to community respiration (AR), and estimated for four Laurentian Great Lakes coastal ... -
Plant Growth-Promoting Bacterial Endophytes that contain ACC Deaminase: Isolation, Characterization, and Use
(University of Waterloo, 2013-04-26)Bacteria that provide benefit to plants are considered to be plant growth-promoting bacteria (PGPB) and can facilitate plant growth by a number of different mechanisms. Plant growth-promoting bacteria that are able to ... -
Plant Growth-Promoting Rhizobacteria (PGPR) Enhanced Phytoremediation of DDT Contaminated Soil
(University of Waterloo, 2008-05-21)Although the pesticide DDT has been banned from use in Canada for more than three decades, DDT still persists in Canadian farmlands at detectable levels. Much effort, such as incineration, thermal desorption, and bioremediation, ... -
Plant growth-promoting root-colonizing bacterial endophytes
(Elsevier, 2021-12)The development of an environmentally friendly agricultural system as opposed to conventional methods using chemical fertilizers and pesticides for improved crop productivity is a promising aspect of modern agricultural ... -
Plant-Growth Promoting Rhizobacteria Enhanced Phytoremediation of Saline Soils and Salt Uptake into Plant Biomass
(University of Waterloo, 2011-07-19)Soil salinity affects an estimated one billion hectares worldwide. Excess salinity inhibits plant growth, limiting crop production. This is caused by osmotic stress in saline soil, nutrient imbalance and specific ion ... -
Polymeric rapid prototyping for inexpensive and portable medical diagnostics
(Society of Photo-optical Instrumentation Engineers, 2012-10-24)The advent of inexpensive CO2 laser systems has led to a wide range of demonstrations of microfabricated lab on chip systems built of acrylic. However, there has been little application of these systems to building ... -
Population Differentiation of Ontario Lake trout (Salvelinus namaycush) using the Major Histocompatibility Complex class II β gene
(University of Waterloo, 2014-06-19)The lake trout (Salvelinus namaycush) is a coldwater salmonid with an extensive native distribution across formerly glaciated regions of North America. Lake trout are known to be a glacial ‘relict’ species and evolved as ... -
Potential Roles for the Neurotrophic Molecules Agrin and Neuregulin in Regulating Aspects of the Inflammatory Response
(University of Waterloo, 2014-05-22)Agrin and neuregulin are neurotrophic molecules well known for their roles at synapses in the peripheral and central nervous systems. The expression of these two molecules is not restricted to these sites however, as they ... -
Potential use of the Oncorhynchus mykiss checkpoint proteins Rad1 and Hus1 as genotoxicity biomarkers
(University of Waterloo, 2011-01-13)Cell-cycle checkpoint proteins help maintain genomic integrity by sensing damaged DNA and initiating DNA repair or apoptosis. Checkpoint protein activation to cell-cycle damaging agents can involve post-translational ... -
A preclinical study of SG pseudopeptide amyloid-β inhibitors for the treatment of Alzheimer’s disease: single molecule force spectroscopy and cell viability
(University of Waterloo, 2017-08-23)Alzheimer's disease (AD) is one of the single greatest healthcare challenges facing our society today with no treatments available that cure, prevent or slow the disease. Neurodegeneration in AD is observed alongside ... -
A preliminary investigation into the ecological significance of headwater drainage features in Southern Ontario
(University of Waterloo, 2010-05-21)Within Southern Ontario urban development is rapidly devouring headwater systems, and this can have significant repercussions to the health of entire river networks. The ecological contributions of headwaters to downstream ... -
Preparative isolation, fractionation and chemical characterization of dissolved organics from natural and industrially derived bitumen-influenced groundwaters from the Athabasca River watershed
(Elsevier, 2021-07-10)Recent analytical advances have provided evidence that groundwater affected by oil sands process-affected water (OSPW) is reaching the Athabasca River at one location. To understand and discriminate the toxicological risks ... -
Primary and Auxiliary Subunits of Sodium Channel Nav1 in Lymnaea Stagnalis
(University of Waterloo, 2014-11-24)Voltage gated sodium channels (Nav ) are major contributors in the neuronal signal transduction, responsible for the action potential upstroke. They are members of the large 4x6 ion channel family, which also include the ... -
Primary Production by Phytoplankton in Lake Simcoe 2010-2011
(University of Waterloo, 2013-05-07)Degradation of water quality, introduction of dreissenid mussels (notably <i>Dreissena polymorpha</i>) and depletion of oxygen concentrations in the hypolimnion in Lake Simcoe, Ontario prompted a study of phytoplankton ... -
The production and fate of picoplankton and protozoa in the pelagic food web of Napoleon Gulf, Lake Victoria, East Africa
(University of Waterloo, 2004)The importance of the microbial food web and how it interplays with the classical food chain has gained considerable attention in temperate lakes. However its role in carbon transfer from pico- and nanoplankton to ... -
Profiling skin-associated archaea and bacteria with 16S rRNA and cpn60 genes
(University of Waterloo, 2021-08-13)As the largest organ of the mammalian body, skin is associated with commensal microorganisms that impact host health. Characterizing host-microbe associations is critical to our understanding of skin health, function, and ... -
