Role Of Ethanol As A Cofactor In Haart Induced Hepatic Steatosis And Injury., Hridgandh Donde
Electronic Theses and Dissertations
Highly Active Antiretroviral Therapy (HAART) has led to a significant increase in the life expectancy of HIV patients; however, there are significant side effects including lipodystrophy and hepatotoxicity. Alcohol abuse is highly prevalent in HIV infected individuals and hence may be a significant negative cofactor in HAART induced hepatotoxicity. The present study examines the mechanisms underlying HAART and alcohol induced hepatotoxicity. The effects of HAART drugs (azidothymidine, and Indinavir sulphate) in combination with alcohol were examined in in vivo animal model. Alcohol and HAART drug interactions and hepatotoxicity were also assessed in-vivo using an animal model of chronic alcohol feeding. …

Ncaa Division I Head Coaches' Experiences With Eating Disorders And Disordered Eating In Female Athletes: A Qualitative Analysis, Caitlyn Pecinovsky
Ncaa Division I Head Coaches' Experiences With Eating Disorders And Disordered Eating In Female Athletes: A Qualitative Analysis, Caitlyn Pecinovsky
Electronic Theses and Dissertations
In today's sport, NCAA Division I female athletes are under a constant pressure to reach an elite level of perfection in athletic performance, frequently adhering to the assumption that there is an inverse relationship between body size and performance level (Petrie & Sherman, 2007). Additionally, coaches have unrealistic expectations about weight and body image, which adds pressure on athletes to conform to certain weight or image driven standards. Perceptions that coaches hold about eating disorders and disordered eating present a set of risk factors that may increase the likelihood of female athletes developing maladaptive eating patterns (Scoffier, Maiano, & d'Arripe-Longueville, …

Improving Chronic Kidney Disease Care With Group Visits, Vicki Montoya
Improving Chronic Kidney Disease Care With Group Visits, Vicki Montoya
Electronic Theses and Dissertations
First year death rates remain unacceptable high for the end-stage renal disease (ESRD) population. New effective methods are vital to improve first year morbidity and mortality outcomes for the population transitioning from Stage 4 chronic kidney disease (CKD) to ESRD)/Stage 5 CKD. Based on current methods, evidence-based recommendations made by nephrology providers are frequently not heeded by patients in Stage 4 CKD. Low levels of patient knowledge, self-efficacy, and a poor ability to self-manage CKD negatively influence a patient’s ability to follow provider recommendations. The group visit (GV) intervention has demonstrated improvements in disease-related outcomes through increased levels of patient …
Ventilator-Associated Complications In The Mechanically Ventilated Veteran, Joan Grano
Ventilator-Associated Complications In The Mechanically Ventilated Veteran, Joan Grano
Electronic Theses and Dissertations
Surveillance of ventilator-associated pneumonia (VAP) has been the common outcome measurement used for internal and external benchmarking for mechanically ventilated patients; and although not a clinical definition, it is commonly used as an outcome measurement for research studies. Criteria in the VAP definition include both subjective and objective components, leading to questions of validity. In addition, recent legislation has mandated the public reporting of healthcare-associated infections, including VAP, in many states. Infectious disease experts have recently recommended monitoring a new outcome, ventilator-associated events (VAE), that contain specific objective criteria. The Centers for Disease Prevention and Control (CDC) have refined this …

Molecular Modeling And Sar Studies Of Cdk5/P25 Selective Inhibitors, Arindam Chatterjee
Electronic Theses and Dissertations
Alzheimer's disease (AD) is one of the most dreaded forms of progressive neurodegenerative diseases. The two main hallmarks of AD are the formation of amyloid senile plaques and neurofibrillary tangles. Cyclin dependent kinase 5 (CDK5) is a proline directed serine/threonine kinase, which expressed primarily in the central nervous system. In the biochemical process the CDK5-natural activator, p35 is cleaved by calpain to a shorter protein p25, which in turn hyperphosphorylates Tau, forms neurofibrillary tangles and causes AD. CDK5 deregulation is also indicated in other neurodegenerative diseases, such as Huntington's chorea, stroke, Parkinson's disease, amyotrophic lateral sclerosis, major depression and substance …

Structural Characterization And Bioactivity Of Cranberry Oligosaccharides, Kimberly M. Auker
Electronic Theses and Dissertations
Complex carbohydrates from plant sources, such as the fruits of cranberry (Vaccinium macrocarpon Aiton), promote human health in a variety of ways. However, complete studies of carbohydrate function often hinge on a detailed understanding and thorough elucidation of the chemical structure. Several methods have been used in the structure elucidation of cranberry oligosaccharides, such as derivatization folloby analysis using gas chromatography-mass spectrometry (GC-MS). In this manner, the identity and quantity of glycosyl units within two cranberry oligosaccharides were investigated through hydrolysis of the oligomers and subsequent synthesis of trimethylsilyl and alditol acetate derivatives. Further analysis using partially methylated alditol acetate …

Scaffold Perception, Compharmacophore Model Development, And Quantitative Structure-Affinity Relationships Of Sigma Site Ligands, David Enos Watson
Electronic Theses and Dissertations
Sigma receptors are endogenous proteins with potential utility in treating psychological disorders, ischemia, the psychological and convulsive effects of drugs of abuse, and as an imaging agent for cancerous tissues, among others. Drug design efforts targeting these receptors have been hindered by a lack of structural information of the receptors themselves. Traditional ligand-based approaches have succeeded in generating many compounds with high affinity, and quite a few with selectivity for σ-1 receptors. There are few selective ligands for use as pharmacological probes for the σ-2 receptor. Much effort has gone into exploring the structure activity relationships of ligands targeting these …
Early And Intermediate Hospital-To-Home Transition Outcomes Of Older Adults Diagnosed With Diabetes, Jacqueline Lamanna
Early And Intermediate Hospital-To-Home Transition Outcomes Of Older Adults Diagnosed With Diabetes, Jacqueline Lamanna
Electronic Theses and Dissertations
Over 5 million older adults with diabetes are hospitalized each year. Though typically not the index condition that leads to hospitalization, diabetes control often decompensates during the course of an admission and necessitates changes in home self-management plans. The specific transitional care needs of older adults with diabetes have been largely unstudied. Transition theory provided the guiding framework for this research and proposes that each transition is a complex process created by the continuous interaction of personal, community, and societal-level conditions that facilitate or inhibit the health of a transition. Hospitalization has been described as a series of three successive, …
The Impact Of Dietary And Exercise Habits On College Students' Life Satisfaction, Megan L. Marsh
The Impact Of Dietary And Exercise Habits On College Students' Life Satisfaction, Megan L. Marsh
Electronic Theses and Dissertations
A majority of college students do not maintain healthy lifestyle practices. Few college students achieve recommendations for adequate nutrition and instead typically consume diets high in fat, sodium, and sugar and low in fruits and vegetables. In addition, few college students meet current physical activity recommendations, and 40-50% do not exercise at all. Life satisfaction is associated with low levels of stress, academic achievement, goal progression, and personal growth initiative, all of which contribute to success in college as well as the transition from college into the working world. Exercise, fruit and vegetable intake, and avoidance of fat intake are …
