Effects of soy and milk ferments on measures of innate immunity: a comparison of effects in normal and microgravity conditions
(2010-07-01)Probiotics can influence intestinal responses and mucosal immunity either directly or indirectly through transient modulation of the endogenous microenvironment or the immune system. During space travel, astronauts experience ... -
The toxicity of Harmony Landfill Leachate to Green Hydra (Hydra viridiisma)
(2010-08-01)Harmony Landfill is a former industrial waste disposal site located adjacent to Harmony Creek in Oshawa, Ontario, Canada. During active disposal, from 1957 until 1980, approximately 1 million tonnes of waste were land-filled ... -
A geophysical and biochemical investigation of buried remains in contrasting soil textures in southern Ontario
(2010-08-01)Ground penetrating radar (GPR) is a non-invasive, geophysical tool used for the detection of clandestine graves. GPR operates by detecting density differences in soil by the transmission of high frequency electromagnetic ... -
Molecular characterization of the binding site of nematode GABA-A receptors
(2010-08-01)Haemonchus contortus is a parasitic nematode that is controlled in large part by nematocidal drugs that target receptors of the parasitic nervous system. Hco-UNC-49 is a nematode GABA receptor that has a relatively low ... -
The Pharmacological Characterization of Hco-UNC-49, a GABA-gated Chloride Channel from the Parasitic Nematode Haemonchus contortus
(2010-08-01)Compared to mammals, nematodes appear to exhibit a unique GABAergic nervous system. Haemonchus controtus is a parasitic nematode that infects ruminants worldwide. Hco-UNC-49 is a H. contortus GABA-gated chloride channel ... -
A survey of algebraic algorithms in computerized tomography
(2010-08-01)X-ray computed tomography (CT) is a medical imaging framework. It takes measured projections of X-rays through two-dimensional cross-sections of an object from multiple angles and incorporates algorithms in building a ... -
Physical and chemical analysis of pig carcass decomposition in a fine sand
(2010-08-01)The development and improvement of methods used for the estimation of the postmortem interval (PMI) is a common area of research in forensic science. This research was conducted to physically and chemically analyze pig ... -
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 ... -
Characterization of novel genetic alleles of cellulose synthase
(2011-01-01)Cellulose is the most abundant polymer on earth. Despite this, relatively little is known about the proteins and biochemical mechanisms governing cellulose biosynthesis. Only in the past 10 years since the sequencing of ... -
CBPsp: complex business processes for stream processing
(2011-04-01)This thesis presents the framework of a complex business process driven event stream processing system to produce meaningful output with direct implications to the business objectives of an organization. This framework is ... -
Graphene and graphane functionalization using hydrogen and nitrogen electronic optical and vibrational signatures
(2011-04-01)Hydrogen is added to Graphene in various compositions and configurations to modify the band structure to produce a suitable band gap for microelectronic applications. Optical and vibrational spectra are calculated as a ... -
Cellulose biosynthesis inhibitors modulate defense transcripts and regulate genes that are implicated in cell wall re-structuring in arabidopsis
(2011-06-01)The cell wall is a multifunctional structure which is implicated in plant growth and development as well as responding to any environmental changes including biotic and abiotic stresses. One of the practical approaches in ... -
A novel method of generating Dendritic cells in vitro using the KG-1 cell line and its use as a model for testing effects of lactic acid bacteria
(2011-08-01)Dendritic cells (DCs) are prime mediators of innate and adaptive immunity. In humans the DC population comprise only 0.1% of all leukocytes, making their isolation and ex vivo manipulation difficult. Since study of DC ... -
The anti-estrogenic and liver metabolic effects of DHAA in rainbow trout (oncorhynchus mykiss)
(2011-08-01)Recent studies have shown that dehydroabietic acid (DHAA), a resin acid present in pulp and paper mills, may have anti-estrogenic effects in fish. A chronic-exposure toxicity experiment using immature rainbow trout (Oncorhynchus ... -
Effects of chronic exposure to ibuprofen and naproxen on Florida flagfish (Jordanella floridae) over one complete life-cycle
(2011-08-01)Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of drugs prescribed to relieve pain, fever and inflammation, and are among the most commonly consumed medications in Ontario. Approximately 70% of the ingested dose ... -
Use of bioelectrical impedance analysis (BIA) to predict water and energy content of juvenile Rainbow Trout (Oncorhynchus mykiss)
(2011-08-01)Accurate measurements of energy content and body composition are essential to effectively assess the well-being of fish. Bomb calorimetry and proximate analysis are currently the most dependable and accurate methods to ... -
