Stress And Coping In Adults With Type 2 Diabetes Who Initiate Insulin Therapy, Maureen A. Loft

Electronic Thesis and Dissertation Repository

Type 2 diabetes affects 90% of people who live with this chronic disease. A primary goal of healthcare professionals is to assist patients with Type 2 diabetes to achieve optimal glycemic control to prevent the devastating complications of this disease. Research has demonstrated that optimal glycemic control can minimize or prevent macrovascular complications such as heart attack or stroke and the microvascular complications of retinopathy, nephropathy, and neuropathy. Historically insulin has been one of the last agents to be added in type 2 diabetes despite its efficacy and long term treatment data. Reluctance by both patients and clinicians to add …

Planting The Chalcone Reductase Family Tree: Identification And Characterization Of Chalcone Reductase Genes In Soybean, Caroline Julia Sepiol

Electronic Thesis and Dissertation Repository

Soybean (Glycine max [L.] Merr) is an important crop grown in Canada, generating $2.4 billion in sales. Though this number may be promising, soybean farmers lose about $50 million worth of yield annually due to root and stem rot disease caused by Phytophthora sojae. Many strategies have been developed to combat the infection; however, these methods are prohibitively expensive. A ‘cost effective’ approach to this problem is to select a trait naturally found in soybean that can increase resistance. One such trait is the increased production of root glyceollins. One of the key enzymes exclusively involved in glyceollin …

Interactions Between The Basolateral Amygdala And Ventral Striatum During Probabilistic Learning In Children And Associations With Individual Differences In Free Cortisol, Haley J. Fallowfield

Electronic Thesis and Dissertation Repository

Stress can drastically alter the behavioural and functional correlates of feedback learning; however, the functional correlates of these effects are poorly understood, particularly in children. In the present study, typically developing children between the ages of 9- and 11-years-old completed a probabilistic learning task with both appetitive and aversive outcomes in a magnetic resonance imaging scanner. Anticipatory stress to the experimental environment was measured via salivary cortisol at baseline and prior to completion of the task. Although baseline and pre-MRI cortisol values were not reliably different at the group level, subsequent analyses revealed that the basolateral amygdala was less responsive …

Nursing Students' Understanding And Enactment Of Resilience: A Grounded Theory Study, Andrew T. Reyes

Electronic Thesis and Dissertation Repository

The purpose of this study was to explore nursing students’ understanding and enactment of resilience. Stress is considered to be a major factor affecting the health, well-being, and academic performance of nursing students. Resilience has been extensively researched as a process that allows individuals to successfully adapt to adversity and develop positive outcomes as a result. However, relatively little is known about the resilience of nursing students. A constructivist grounded theory study design was used. In-depth individual interviews were conducted with 38 nursing students enrolled in a four-year, integrated baccalaureate nursing degree program at a university in Ontario, Canada. Face-to-face …
