A Novel Role For Osteopontin In Facilitating West Nile Virus Neuroinvasion, Amber M. Paul

Dissertations

West Nile virus (WNV) is a positive-sensed, single-stranded RNA flavivirus that can cause human neuroinvasive diseases, including encephalitis, meningitis, and flaccid paralysis. The mechanisms by which WNV enters the central nervous system and the host-factors that are involved in WNV-neuroinvasiveness are not completely understood. Osteopontin (OPN), a multifunctional glycoprotein, has been implicated as a bio-marker for a number of neuroinflammatory diseases. In particular, secreted (s)OPN has been implicated to participate in recruitment of polymorphonuclear neutrophils (PMN) to sites of its expression, while PMNs have been suggested to act as WNV reservoirs. Therefore, sOPN recruitment of PMNs may contribute to neuroinvasive …

Defining Deliberate Practice In Supervised Dietetics Education, Kevin D. Haubrick

Dissertations

Deliberate practice serves as a potential framework to understand what activities, attributes, and characteristics make an individual an expert in their chosen field or profession.

Deliberate practice has never been defined within the context of supervised dietetics education; therefore, the purpose of this research was to develop a valid and reliable instrument to define deliberate practice in supervised dietetics practice, based on the opinions of practitioners and educators in dietetics and allied health professions. Segment one of the research …

The Design Of An Instrument To Assess Clinical Laboratories Efficacy Post Implementation Of The Patient Protection Affordable Care Act, Harry Mcdonald Jr.

Dissertations

The healthcare system in the United States has undergone substantial changes in support of the Patient Protection and Affordable Care Act (PPACA). On March 23, 2010, the implementation of the new healthcare law brought universal healthcare access to all Americans, while attempting to increase quality and decrease medical costs. The new law promotes more of a quality-focused, outcome-based model rather than a pay-for-fee service model; thus, moving the paradigm from infrequent to preemptive healthcare. The PPACA postulates as the only way to achieve cost savings while increasing quality and access. Never before has there been such an extensive change to …

Elucidating The Role Of Interleukin-17a In West Nile Virus Infection, Dhiraj Acharya

Dissertations

West Nile virus (WNV) is a neurotropic flavivirus of significant public health importance for which no therapeutics and vaccine are currently available. Interleukin-17A (IL-17A) is an inflammatory cytokine that regulates diverse immune functions, while its role is unclear in host’s immune response to WNV. Furthermore, CD8⁺ T cells are crucial components of immunity and play a vital role in recovery from WNV infection. Here, we report a previously unrecognized function of IL-17A in regulating CD8⁺ T cell cytotoxicity. We show that WNV induces the expression of IL-17A in both mouse splenocytes and human peripheral blood mononuclear cells cultured …

Study Of Rickettsia Parkeri Colonization And Proliferation In The Tick Host Amblyomma Maculatum (Acari: Ixodidae), Khemraj Budachetri

Dissertations

Amblyomma maculatum (Gulf coast tick) ticks are prevalent across the Atlantic to Gulf Coast region of United States. These ticks are recognized vectors of Rickettsia parkeri, a spotted fever group of Rickettsia (SFGR) known to cause American boutonneuse fever associated with fever and eschar rashes localized to the site of bites. We hypothesized that Rickettsia parkeri colonization and proliferation in the tick vector involve pathogen-symbiont dynamics and tick-pathogen interactions, which influence rickettsial transmission to the victims after tick bites. The rickettsial infection is maintained across the tick life cycle for many generations due to transovarial and transstadial transmission of …

A Motivational Profile Of Nurses Who Pursue Doctoral Education, Tomekia Yvette Luckett

Dissertations

The need for nurses to pursue doctoral education is imperative to the professionalization of the discipline of nursing in light of the changing healthcare environment. Presently, < 1% of the nursing workforce possesses a doctoral degree (“Transforming Nursing Education,” 2016), albeit recommendations from the Institute of Medicine (IOM) (2010) admonish the need to increase the number of doctoral-prepared nurses. The need to understand characteristics of nurses who seek doctoral education is critical in planning long-term strategies for nursing education in the United States (US) (Kovner, Brewer, Katigbak, Djukic, & Fatehi, 2012). In conjunction with describing characteristics of nurses pursuing doctoral education, this research describes the motivational orientation and factors of registered nurses (RNs) pursuing doctoral education.

A descriptive correlational design was utilized to examine concepts relating to motivational orientation of RNs pursuing doctoral education. Participants were divided into two categories: (a) RNs seeking the Doctor of Philosophy (Ph.D.) degree and (b) RNs pursuing the Doctor of Nursing Practice (DNP) degree. A total of 173 RNs enrolled in either a Ph.D. or DNP program in the Gulf South region of the US comprised the final sample. Binary logistic regression was utilized …
