The Role Of Antioxidant Rich Berries In The Prevention Of Postmenopausal Bone Loss, Lydia Karimi Kaume
The Role Of Antioxidant Rich Berries In The Prevention Of Postmenopausal Bone Loss, Lydia Karimi Kaume
Graduate Theses and Dissertations
Postmenopausal osteoporosis is the most prevalent form of osteoporosis and results in fragility fractures. Smoking is one of the major risk factors for osteoporosis and is known to aggravate bone loss in postmenopausal women due to increased oxidative stress and inflammation. Diet-based interventions using berries have shown bone protective affects in animal studies partially due to antioxidant and anti-inflammatory properties of their phenolic compounds. The goal of this research was to determine the effects of antioxidant-rich fruits in the prevention of postmenopausal bone loss. Our first study examined the dose dependent effects of blackberries in preventing bone loss in an …
Effects Of Head Position And Head-Supported Mass On Nerve Function Of The Flexor Carpi Radialis Muscle In Healthy Individuals, Bethany Lauren Shivers
Effects Of Head Position And Head-Supported Mass On Nerve Function Of The Flexor Carpi Radialis Muscle In Healthy Individuals, Bethany Lauren Shivers
Graduate Theses and Dissertations
Long-term exposure to head-supported mass (HSM) has been linked with spinal degeneration including foraminal stenosis and disc deterioration. Anecdotally, HSM has also been linked to neck and arm pain and muscle atrophy, but nerve function has not been tested specifically. The combined effect of various head positions and HSM may be sufficient to compress the nerve root in aviators and Soldiers during job performance, potentially leading to short- and long-term neuromuscular effects. The Hoffmann (H) reflex, a well-established measure of nerve function, has shown to be sensitive to changes in nerve root space which occurs with different head positions. This …
The Use Of Cortisol And Hba1c As Biomarkers Of Stress In University Administrators, Jacilyn Marie Olson
The Use Of Cortisol And Hba1c As Biomarkers Of Stress In University Administrators, Jacilyn Marie Olson
Graduate Theses and Dissertations
PURPOSE: The purpose of this study was to explore the impact of perceived stress and cardiorespiratory fitness on cortisol and HbA1c, biomarkers of stress, in a group of select university administrators. The impact of gender on these relationships was of special concern. METHODS: University administrators with job titles of Chancellor, Provost, Vice Chancellors and Vice Provosts of the university, and Deans and Associate Deans at the college level were recruited. Twenty-five administrators (15 males and 10 females) agreed to participate and completed a battery of assessments that included completion of the University Administrative Concerns Questionnaire, a finger-stick blood test for …
Investigation Of A Locus On Chromosome 9 For Contributions To Pulmonary Hypertension Syndrome In Broilers, Sriram Krishnamoorthy
Investigation Of A Locus On Chromosome 9 For Contributions To Pulmonary Hypertension Syndrome In Broilers, Sriram Krishnamoorthy
Graduate Theses and Dissertations
Although the ascites syndrome in chickens has been investigated for years, it continues to inflict financial losses to the world poultry industry. It is estimated that 8% of the 361 million broiler deaths are due to ascites leading to losses of millions of dollars annually. Efforts to curb the incidence of ascites are typically designed to slow early growth. This limits the birds' ability to show its true genetic potential and impacts later yields. In 1994 lines divergent for susceptibility to ascites were established from a commercial sire line through sibling selection of birds reared at local altitude after testing …
A Role Of Environmental Components In Autoimmune Vitiligo Of Smyth Line Chickens, Lei Dong
A Role Of Environmental Components In Autoimmune Vitiligo Of Smyth Line Chickens, Lei Dong
Graduate Theses and Dissertations
The Smyth line (SL) of chickens is a well-established animal model for the study of spontaneous autoimmune vitiligo, displaying all the characteristics of human vitiligo. In humans, phenolic derivative 4-tertiary butyl phenol (4-TBP) has been shown to trigger vitiligo in susceptible individuals. In vitiligo-prone SL-chickens, live turkey herpesvirus (HVT) infection at hatch was identified as the most effective trigger of SL-vitiligo expression. This dissertation examined the role of the environmental factors 4-TBP and HVT in the etiology of SL-vitiligo. Specifically, the generation of reactive-oxygen-species by melanocyte-containing feather tissue (MC-FT) and cultured melanocytes in response to 4-TBP exposure in vitro (Study …
Interactions Of Nitric Oxide And Superoxide Pathways In Hyperglycemic Endothelial Cells, Steven Clay Rogers
Interactions Of Nitric Oxide And Superoxide Pathways In Hyperglycemic Endothelial Cells, Steven Clay Rogers
Graduate Theses and Dissertations
Cardiovascular complications arising from diabetic hyperglycemia represents one of the leading causes of death and greatest public health challenges of modern societies. Despite state-of-the-art glucose control, diabetic patients remain at a markedly increased risk of cardiovascular disease. The loss of endothelial function (the development of diabetic endothelial dysfunction) has been implicated in the development of numerous diabetic cardiovascular diseases. The endothelial cell produces many vasoactive substances, hormones and cytoprotective biological factors. Endothelial cells are also involved in and affected by the initiation of inflammatory responses through the release and interaction of cytokines and other immune system molecules. Therefore, regulation of …
