Targeting Sphingosine Kinase 2 As A Treatment For Cholangiocarcinoma, Anthony D. Stillman

Theses and Dissertations

Cholangiocarcinoma (CCA) has a high mortality rate and its occurrence is rising. This increase prompts the need for improved CCA treatments. Studies have suggested that CCA is highly reliant on the sphingosine-1-phosphate-receptor-2 (S1PR2) and sphingosine kinase 2 (SphK2). Recently, a competitive SphK2 inhibitor, ABC294640, has been approved for clinical trial. ABC294640 has the potential to treat CCA, which is support by a phase I clinical study that was able to temporarily treat a patient suffering from metastasized CCA with ABC294640. To determine the viability of ABC294640 as a treatment for CCA, this study focused on determining the effects of ABC294640 …

2nd Tier Assay For The Detection Of Congenital Adrenal Hyperplasia By Virginia’S Newborn Screening Laboratory: Steroid Profile By Hplc-Ms/Ms, Christopher E. Nixon

Theses and Dissertations

Congenital Adrenal Hyperplasia (CAH) encompasses several disorders related to disruptions in the adrenal steroid production pathway. These disruptions may cause virilization of the external female sex organs, incorrect gender assignment, precocious puberty, and in the most severe form, may cause life-threatening salt wasting and adrenal crisis if not detected and treated early in the newborn period.

17α-Hydroxyprogesterone (17-OHP) is the primary target for immunofluorescence detection of CAH from dried blood spots in newborn screening (NBS). Unfortunately, current immunoassay techniques for the detection of CAH suffer from high false positive rates. The primary factors contributing to false positive determinations can include …

The Influence Of Training On Kinematics Related To Knee Injury In Novice Runners, Kathryn Harrison

Theses and Dissertations

Running is known to provide important health benefits. However, the incidence of injury among runners is high, particularly among novice runners, which discourages long term participation in the sport. The knee is the most commonly injured joint in novice runners. In general, aberrant frontal and transverse plane kinematics are associated with the development of knee injuries in runners. It was unknown whether the high rate of knee injury in novice runners was due to abnormal kinematics. Further, it was unclear whether these risk factors for injury could be improved. This dissertation includes four studies investigating kinematics in novice runners, how …

Motivational Interviewing In A Team-Based Wellness Clinic: Perceptions And Fidelity, Jodi M. Winship

Theses and Dissertations

INTRODUCTION: Motivational Interviewing (MI) is an evidenced based counseling style to elicit health behavior change. Team-based student clinics are an ideal climate for students to learn and practice team-based care, yet little is understood as to how client-centered communication styles such as MI are implemented in a team setting.

PURPOSE: The purpose of this dissertation was to conduct an exploratory study using mixed methods to better understand how an MI training translates to team-based communication with clients, the factors impacting team-based implementation of MI, and how team-based MI impacts clients’ perceived autonomy at a student-led, interprofessional, team-based wellness clinic for …

Stat5b And Stat5 Tetramers Are Essential For Ige-Mediated Mast Cell Function, Kasalina N. Kiwanuka

Theses and Dissertations

Signal Transducers and Activators of Transcription (STATs) are latent transcription factors that mediate several cellular responses. This protein family consists of seven members, STAT1 – 6 including two closely related molecules, STAT5a and STAT5b, that show 96% amino acid sequence homology and are critical for lymphoid, myeloid and erythroid cell development and function. Activated STAT proteins dimerize and translocate to the nucleus, where they bind to high-affinity DNA motifs to modulate gene expression. We recently identified STAT5b as the critical regulator of IgE-mediated cytokine production in mast cells. STAT5b knockout (KO) cells show decreased sensitivity to IgE-mediated passive systemic anaphylaxis …

An Evaluation Of Differences In Motivations To Receive Cervical Cancer Screening And Follow-Up Care Between Black And White Women, Ashlee Sawyer

Theses and Dissertations

Background: Cervical cancer among Black women is a major individual and public health concern. Despite advancements in medical technology and policy, disparities in cervical cancer diagnosis and mortality still exist between White and Black women, with Black women having higher rates of diagnosis (10.0 vs 7.1 per 100,000) and mortality (4.1 vs 2.0 per 100,000). Previous studies have focused heavily on barriers to obtaining cervical cancer screening among Black women and efforts to improve screening rates. Despite speculation by researchers that gaps in receipt of quality follow-up care may contribute to disparities, its role in disparate mortality rates between Black …

Pharmacological Assessment Of Adjuncts To Enhance Mu-Opioid Receptor Agonist Antinociception In Male Rhesus Monkeys: Does One + One = Three?, Jeremy Cornelissen

Theses and Dissertations

Mu-opioid receptor (MOR) agonists are effective agents for pain management, but are also limited by a number of undesirable effects. One approach to enhance the therapeutic effects and minimize the undesirable effects of MOR agonists may be to combine MOR agonists with an adjunct targeting a different receptor system. This targeted medical approach, known as “combination therapy”, aims to augment the desired effects of the MOR agonist (i.e. antinociception) and/or diminish the undesirable deleterious side effects of the MOR agonist. This dissertation investigated the utility of this approach in an assay of thermal nociception and schedule-controlled responding in male rhesus …

Examining Sleep And Family Functioning In Pediatric Craniopharyngioma Using Ecological Momentary Assessment, Nour Al Ghriwati

Theses and Dissertations

Craniopharyngiomas are among the most common brain tumors in children and are associated with greater rates of sleep problems compared to other pediatric cancers. However, research examining sleep among youth with craniopharyngioma has been limited by a reliance on retrospective reports or sleep studies. Families also play a crucial role in children’s adjustment following a pediatric cancer diagnosis, yet remarkably little is known about transactional associations between family functioning and sleep in pediatric cancer. This study examined cross-sectional and daily associations among family functioning, affect, and sleep difficulties for youth with pediatric craniopharyngioma using retrospective reports and ecological momentary assessment …

Molecular Pharmacology Of Non-Phyto-Cannabinoid Approaches For Treatment Of Neuropathic Pain, Nadejda A. Blajkevich

Theses and Dissertations

Approximately twenty million people in United States have some form of peripheral neuropathy. It has been shown that the CB₂ cannabinoid receptor is upregulated when there is peripheral nerve injury and activating the CB₂ receptor produces anti-inflammatory effects that translate to a reduction in signs of “neuropathic pain” in animal models. Elevating endogenous cannabinoids by inhibiting degradative enzymes has also been used to reduce neuropathic pain signs in laboratory animal models of pain. We hypothesize that the molecular pharmacology of these two approaches can be leveraged to optimize CB₁/CB₂ activation to improve non-phyto-cannabinoid treatments for …

The Effect Of Quercetin In Periodontal Inflammation, Sara Holden

Theses and Dissertations

Purpose: To determine the effect of Quercetin, a plant based over the counter flavonoid, on periodontal inflammation in a murine model of periodontitis.

Methods: Periodontitis was induced in age and gender matched mice (C57BL/6) using ligatures on the left side of the maxilla and right side was left un-ligated as baseline control. The animals received daily Quercetin gavage or Phosphate Buffered Saline (PBS) starting 5 days prior to ligation which continued throughout the experimental protocol. Micro-computed tomography (micro CT) imaging was used to determine alveolar bone loss. Real Time quantitative (qRT) PCR was used to determine level of gingival tissue …
