Characterization of the ACC-1 Family of cys-loop ligand gated ion channels from the parasitic nematode Haemonchus contortus.
(2020-12-01)Nematode cys-loop ligand-gated ion channels (LGICs) have been extensively studied for decades because of their role in current anthelmintic action and potential as targets for future drugs. Many families of cys loop receptors ... -
Characterization of two component systems of Acinetobacter baumannii.
(2014-10-01)Acinetobacter baumannii is an important opportunistic pathogen of hospital acquired infection, particularly in intensive care units. The emergence and rapid spread of multidrug-resistant A. baumannii strains has become a ... -
Characterization of xylan degradation systems in streptomyces
(2012-07-01)Plant biomass serves as a carbon and energy source for Streptomyces spp. which secrete degradative enzymes capable of breaking down the complex plant biomass into simple saccharides. Hemicellulose is a major component of ... -
Characterizing blood plasma proteins from organ tissue in rainbow trout (Oncorhynchus mykiss) using a non-targeted proteomics approach
(2021-12-01)Protein expression patterns adapt to various cues to meet the needs of an organism. The dynamicity of an organism’s proteome can therefore reveal information about an organism’s health. Proteome databases contain limited ... -
Characterizing immunomodulatory activity of lactic acid bacteria on cell types involved in innate immunity: analysis of the effects of Lactobacillus rhamnosus R0011-derived milk ferments on macrophage polarization and of secretome effects on intestinal epithelial cell cytokine production
(2015-07-01)Probiotic lactic acid bacteria have been associated with a wide array of host-immune modulatory effects including down-regulation of pro-inflammatory gene transcription and expression following pro-inflammatory challenge, ... -
Characterizing Plankton communities in Lake Ontario coastal wetlands along an urban land-use gradient
(2020-04-01)This thesis presents the results of a study on the effect of habitat condition and water quality on plankton communities across an urban land-use gradient in the Lake Ontario coastal wetlands: Frenchman’s Bay, Lynde Marsh, ... -
Characterizing the potential energy surface of two dimensional and bulk materials using high dimensional neural network potentials
(2018-08-01)Computing material properties at the ab-initio level of detail is computationally prohibitive for large systems or long timescales. As a result, such methods cannot be used to efficiently sample configuration space. Force ... -
Characterizing water-metal interfaces and machine learning potential energy surfaces
(2017-08-01)In this thesis, we first discuss the fundamentals of ab initio electronic structure theory and density functional theory (DFT). We also discuss statistics related to computing thermodynamic averages of molecular dynamics ... -
Chronic effects of single intra-peritoneal injection of endosulfan on rainbow trout (Oncorhynchus mykiss) and field observations of caged rainbow in Oshawa Creek
(2009-08-01)The organochlorine pesticide endosulfan has been shown to be highly toxic to fish and there is some evidence to support that it may act as an endocrine disrupting chemical. Juvenile rainbow trout (Oncorhynchus mykiss) were ... -
Chronic toxicity of phthalates, biphenol and a Canadian bottled water stored under different light regimes using the Cnidarian Hydra Viridissima©
(2009-08-01)There is general concern whether human exposure to selected Canadian bottled waters and the chemicals which may leach from them, could potentially cause deleterious effects. This research was designed to determine whether ... -
Cloning and characterization of AdeMNO RND efflux pump of Acinetobacter baumannii
(2010-11-01)Acinetobacter baumannii is an opportunistic pathogen which has been implicated in a variety of nosocomial infections among immunocompromised patients worldwide. Recently, Multi-drug resistant (MDR) isolates of A. baumannii ... -
Cluster techniques and prediction models for a digital media learning environment
(2012-08-01)The present work applies well-known data mining techniques in a digital learning media environment in order to identify groups of students based on their pro le. We generate identi able clusters where some interesting ... -
Cluster-based target tracking in vehicular ad hoc networks
(2015-01-01)Recently Vehicular Ad-hoc Networks (VANETs) have drawn the attention of academic and industry researchers due to their potential applications in enabling Intelligent Transportation System (ITS), including safe driving, ... -
Cognitive function during exertional heat stress assessed using traditional and serious game technology
(2016-06-01)Firefighting is a physically demanding occupation requiring intermittent bouts of work resulting in increased levels of cardiovascular and thermal strain, while making decisions requiring higher order cognitive abilities ... -
A coherent point drift algorithm for breast image registration via surface markers
(2017-03-01)Breast Magnetic Resonance Imaging (MRI) is a reliable imaging tool for localization and evaluation of lesions prior to breast conserving surgery (BCS). MR images typically will be used to determine the size and location ... -
A "Communication Skills for Computer Scientists" Course
(ACM, 2009-07)This paper describes "Communication Skills for Computer Scientists," a novel undergraduate course at the University of Toronto. We describe in detail the three major instructional streams of the course: writing, speaking, ... -
Community-oriented architecture for smart cities
