The Relationship Among Wellness, Severity Of Disturbance, And Social Desirability Of Entering Master's-Level Counseling Students, Heather Smith

Electronic Theses and Dissertations

A wellness paradigm may hold promise for unifying and strengthening the identity of the counseling profession. The construct of wellness may also hold implications for assessment of entering master's-level counseling students, as a tool for continuous evaluation of students, or for overall program evaluation. In this study, the only counseling-based wellness assessment measure, the Five Factor Wellness Evaluation of Lifestyle, was tested for its relationship to two other constructs: psychological disturbance and social desirability. In order to test the research hypotheses, a total of nine programs (in five states) and 204 entering master's-level counseling students completed instrumentation packets comprised of …

Minority Physician Job Satisfaction: A Content Analysis Of Written Responses To Open-Ended Survey Questions About Professional A, Devorah Daniels-Kranz

Electronic Theses and Dissertations

Few interpersonal and organizational communication studies examine the professional and organizational aspects of career satisfaction among minority physicians. Due to the underrepresenation of minority physicians, most studies resort to comparing aggregate groups of minority physicians in juxtaposition to non-minority physicians. These studies fail to uncover possible communication differences, which originate from cultural dissimilarities between disaggregate racial/ethnic groups. Even fewer studies examine physicians' written communication to open-ended survey questions about career satisfaction/dissatisfaction between disaggregate racial/ethnic minority groups and non-minorities. This study specifically examines written responses to two open-ended survey questions about professional and organizational dissatisfaction and compares responses from disaggregate minority …

Molecular And Biochemical Changes In The Ileum Of Weanling Pigs Fed Antibiotics As Growth Promotant And In Germ-Free Conditions, Sajan George

Electronic Theses and Dissertations

Antibiotics are routinely fed as growth promoters to weanling pigs for the past 50 years. However, frequent use of feed antibiotics potentially results in emergence of drug resistance in microbes, which could be transferred to human pathogens and would interfere with the effective use of therapeutic antimicrobials in human medicine. Such health concerns about the use of antibiotics in animal feeds have led to considerable scientific research and debates. Recently, use of antibiotics in animal feeds has been banned in the European Union and would possibly impact US agriculture soon. This study was conducted to understand the molecular mechanisms of …

Characterization Of Microbial Communities In Karstic Sediments : A Study Of Cave Bacteria In Central Kentucky., Justine Kay Roback 1964-

Electronic Theses and Dissertations

Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters. Here, bacterial communities from four distinct cave sediments collected in central Kentucky and adjacent surface streams were compared using a combination of culture and molecular methods. Predictions were that: 1) Cave communities will have unique community structures when compared to those of nearby surface sediments, and 2) Genetic diversity of bacterial communities in cave sediments will be higher than those in nearby surface sediments. Since diversity and community structure …

Induction Of Lineage And Differentiation Of Adult Human Neuroepithelial Progenitors In Vitro., Xiaodong Zhang 1968-

Electronic Theses and Dissertations

Neurosphere forming cells (NSFCs) have been derived from cultures of adult olfactory neuroepithelium obtained from patients and cadavers in serum rich medium. These neural progenitors remain undifferentiated when maintained in serum rich medium but have the potential to differentiate along glial or neuronal lineages. A totally defined medium (DM) was employed to examine their proliferation, lineage restriction and differentiation. None of the neurotrophic factors evaluated increased NSFCs viability or lineage restriction under the defined experimental conditions. Few of NSFCs ever express mature neuronal or glial markers in DM. To evaluate the potential of NSFCs to form oligodendrocytes, transcription factors, Olig2, …

Effects Of Food Deprivation On Blood Lipid Concentration And Composition In Steller Sea Lions (Eumetopias Jubatus), Michelle Lea Berman

Electronic Theses and Dissertations

Steller sea lions, the largest Otariid, fast during their breeding season; during this time they refrain from ingesting food for a period of 12-43 days. Fasting, while undertaking an extremely energetically demanding activity (breeding and pupping), requires specific physiological adaptations. This study examined the physiological response to fasting of two age classes, juveniles and sub-adults, during the breeding and non-breeding seasons to determine how these animals utilize lipids and the pattern of fatty acid mobilization from lipid stores during fasting. Four juveniles and 5 sub-adults were fasted for one and two weeks, respectively, and blood samples were collected approximately every …

Novel Protein-Protein Interactions Regulate The Proteolytic Activity Of The Pro- Apoptotic Serine Protease, Omi/Htra2, Supriya Singh

Electronic Theses and Dissertations

Omi/HtrA2 is a mitochondrial serine protease with high homology to the bacterial HtrA proteins. Omi promotes caspase-dependent apoptosis by binding and degrading IAPs-inhibitor of apoptosis proteins. Omi can also induce caspase-independent apoptosis but the actual mechanism is still unknown. IAP's are not the only substrates cleaved by Omi. There are at least two more known substrates of Omi, the HAX-1 and the ped/pea-15 proteins. HS1-associated protein X-1 (HAX-1) is a mitochondrial protein, degraded by Omi after induction of caspase-dependent apoptosis. Ped/pea-15 is also an anti-apoptotic protein and is cleaved by Omi after induction of caspase-independent apoptosis. The proteolytic activity of …

Selenotrisulfide Derivative Of Alpha-Lipoic Acid: Evaluation In A Cell Culture Model For Potential Use As A Topical Antioxidant, Melenie Lee Alonis

Electronic Theses and Dissertations

Selenium is a required micronutrient in mammalian cells. It is incorporated in the form of selenocysteine into selenoenzymes such as glutathione peroxidase and thioredoxin reductase, and is absolutely required for activity. Thioredoxin reductase is necessary for reduction of oxidized thioredoxin and therefore plays a major role in maintaining the redox status of the cell. Glutathione peroxidase is responsible for reducing peroxides into their corresponding alcohols and water. Together, these selenoenzymes constitute a significant part of the cell's arsenal to defend itself against oxidative stress. Exogenous sources of oxidative stress, such as UV radiation, are capable of generating reactive oxygen species …

Life Event Perception: A Structural Equation Modeling Approach To The Antecedents Of The Life Stress Response, Christopher Aaron Myers

Electronic Theses and Dissertations

It has been often argued that life events have an impact on our physical and psychological well-being. In general, research supports this connection between life events and general health, though some argue that simply experiencing life events has a measurable and predictable impact our health, while others contend that this effect is mediated by the appraisal process. Further, research has identified a number of different factors (hypothetically stratified into pre-existing beliefs, external resources and demands, and behavioral activation and coping strategies) that may influence appraisal and general health. The current study attempts to integrate these findings by testing structural models …
