Food Shopping Habits And The Association With Diet, Crystal Danielle West

Theses and Dissertations--Nutrition and Food Systems

Research suggests that the connection between poor diet and obesity among rural residents may be partially explained by limited access to healthy foods including fruits and vegetables (F&V). Based on federal suggestions to improve access, the purpose of this study was to assess the relationship between food shopping habits food venues and dietary intake of residents in rural counties of Kentucky. In May, 2013, a telephone survey was conducted using random-digit dial methods among n=149 participants in all three counties. Results showed that grocery shopping at supermarkets had a moderate positive correlation with F&V intake (r=.357, .348). These findings suggest …

The Role Of Angiotensinogen In Atherosclerosis And Obesity, Congqing Wu

Theses and Dissertations--Nutritional Sciences

Angiotensinogen is the only known precursor in the renin-angiotensin system, a hormonal system best known as an essential regulator of blood pressure and fluid homeostasis. Angiotensinogen is sequentially cleaved by renin and angiotensin- converting enzyme to generate angiotensin II. As the major effector peptide, angiotensin II mainly function through angiotensin type 1 receptor.

Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and more recently renin inhibitors are widely known as the 3 classic renin-angiotensin system inhibitory drugs against hypertension and atherosclerosis. Here, we developed an array of regents to explore the effects of angiotensinogen inhibition. First, we demonstrated that genetic deficiency of …

Leptin Resistance Induced Obesity And Diabetes Promote Neuropathological Changes In The Aging Brain, Thomas Platt

Theses and Dissertations--Molecular and Cellular Biochemistry

The aging brain is prone to the development of pathology and dementia. With a rapidly growing elderly population diagnoses of neurodegenerative diseases, such as Alzheimer’s disease (AD), frontotemporal dementia (FTD), and Parkinson’s disease are on the rise. Additionally, diabetes and obesity are linked to an increased risk of dementia. The convergence of this increasingly aged population with the obesity and diabetes epidemic give rise to new concerns regarding the future of prevention and treatment of neurodegenerative diseases. Our lab has previously shown that leptin, an adipokine involved in signaling satiety to the hypothalamus, can modulate the generation of the amyloid …
