Producing A Subunit Vaccine For Porcine Epidemic Diarrhea Virus, Zayn Khamis Dec 2016

Producing A Subunit Vaccine For Porcine Epidemic Diarrhea Virus, Zayn Khamis

Electronic Thesis and Dissertation Repository

Porcine epidemic diarrhea virus (PEDv) causes disease and mortality to piglets worldwide. Most vaccines used to combat the disease have been ineffective live attenuated virus vaccines. The goal of this project was to produce a plant-made subunit vaccine based off the membrane protein of the virus. This is the first time this protein has been produced in plants. An elastin-like polypeptide fusion membrane protein accumulated up to 0.8 mg/g of fresh leaf weight when transiently expressed in Nicotiana benthamiana. Virus-like particles were also produced for the first time for PEDv, and were able to form with just the membrane …


Is Online Motor Control Really Impaired In Parkinson's Disease?, Kate E. Merritt Aug 2016

Is Online Motor Control Really Impaired In Parkinson's Disease?, Kate E. Merritt

Electronic Thesis and Dissertation Repository

Patients with Parkinson’s disease (PD) are thought to be selectively impaired in consciously-mediated online automatic motor control, whereas the ability to perform subconscious online adjustments remains intact. This present study evaluates the hypothesis that the previously alleged deficits in online motor control in PD are not due to the consciousness of the correction, but rather are attributable to aspects of the prior experimental designs disproportionately penalizing patients for PD-related bradykinesia. Here, we implemented a modified traditional double-step paradigm to investigate consciously-mediated online motor control in PD, in a manner that would be unconfounded by disease-related bradykinesia. Further, we investigated the …


Panx1 And Panx3 Regulate Adipocyte Development And Fat Accumulation In Vivo, Vanessa R. Lee Aug 2016

Panx1 And Panx3 Regulate Adipocyte Development And Fat Accumulation In Vivo, Vanessa R. Lee

Electronic Thesis and Dissertation Repository

The obesity epidemic is a growing concern due to its various comorbidities and associated risk factors. Pannexins 1 and 3 (Panx1 and Panx3), are members of a family of channel-forming glycoproteins that have been reported to be important in paracrine signaling and development. Panx1 and Panx3 are homologous and are regulated in many different cell types, mediating cell proliferation and differentiation. We have shown that Panx1 and Panx3 are expressed in adipocytes and adipose-derived stromal cells (ASCs) throughout the process of differentiation. Mice globally lacking Panx1 (Panx1 KO) have significantly greater total fat mass compared to wildtype (WT) mice under …


Beta Blocker Dialyzability And Effectiveness In Chronic Hemodialysis Patients, Alvin Tieu Jul 2016

Beta Blocker Dialyzability And Effectiveness In Chronic Hemodialysis Patients, Alvin Tieu

Electronic Thesis and Dissertation Repository

Of the minimal information describing drug dialyzability, the majority was obtained prior to modern hemodialysis membranes. This study characterized the dialyzability of the most commonly prescribed beta blockers in patients undergoing high-flux hemodialysis. Eight subjects were recruited to a pharmacokinetic, 4-way crossover trial. Drug concentrations were measured using mass spectrometry and dialyzability determined by the arterial-venous difference and recovery clearance methods. A provincial-wide retrospective cohort study was designed to determine the effect of dialyzability on adverse clinical outcomes. Beta blocker efficacy can be hindered if substantial clearance occurs during dialysis. Our results demonstrate atenolol and metoprolol are extensively cleared during …


Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock Jul 2016

Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock

Electronic Thesis and Dissertation Repository

We conducted a randomized controlled trial to evaluate patients undergoing a total hip arthroplasty (THA) who were discharged from the hospital either on the day of surgery (outpatient) or were admitted overnight following surgery (inpatient). Our primary outcome was the rate of serious adverse events during the first three months postoperatively. Secondary outcome measures included cost, patient satisfaction, functional outcomes, quality of life and pain. We found no statistically significant difference between the two groups in serious adverse events. We found that outpatient THA was less expensive from the perspectives of the hospital and ministry of health; but the difference …
