Alterations In Rhythmic Licking Behaviors Following Fibrosis In The Rat Mylohyoid Muscle., Brittany Fletcher May 2019

Alterations In Rhythmic Licking Behaviors Following Fibrosis In The Rat Mylohyoid Muscle., Brittany Fletcher

Electronic Theses and Dissertations

Muscle injury is a common side effect of radiation treatment for head and neck cancer. To increase understanding of muscle injury related dysfunction, we investigated the effects of oral swallowing function after cryoinjury to mylohyoid muscle in rats. The hypothesis is that injury to the mylohyoid delays the temporal licking pattern, resulting in aberrant drinking behaviors. Six rats received bilateral mylohyoid injuries by applying a 3mm cryoprobe. Licking behavior was measured by electrophysiological recordings of rhythmic tongue movements in a ten-minute drinking session taken pre-and post-injury (one-and two-weeks). Lick frequency and total licks per cluster decreased significantly one-and two-weeks post-injury …


The Shape Study : The Survey Of Health And The Perceived Environment Study., Colette Patrice Davis May 2019

The Shape Study : The Survey Of Health And The Perceived Environment Study., Colette Patrice Davis

Electronic Theses and Dissertations

Introduction: Few studies have considered how an individual’s perception of their built environment may be a risk factor for being overweight or obese. Adolescents may be particularly vulnerable in the context of “impoverished environments”, which they may perceive to be difficult, dangerous, resource deficient, and unaesthetic. This study aids in clarifying how the built environment influences the risk of obesity among adolescents residing in a neighborhood in Louisville, KY. Objective: The overall objective was to conduct a cross-sectional epidemiologic pilot study among adolescents aged 12-17 years residing in West Louisville, Kentucky to evaluate the association between perceptions of …


Synthesis, Characterization, And Evaluation Of Metal Complexes With Cancer Selective Anti-Proliferative Effects And Hydrogen Evolution Catalytic Properties., Nicholas Vishnosky May 2019

Synthesis, Characterization, And Evaluation Of Metal Complexes With Cancer Selective Anti-Proliferative Effects And Hydrogen Evolution Catalytic Properties., Nicholas Vishnosky

Electronic Theses and Dissertations

Bis-thiosemicarbazones (BTSC) and their metal chelates have properties that are useful in several different scientific fields. These systems have already received attention in major fields of biology and engineering. Hydrogen evolution reaction (HER) catalysts need to be cheap and operate under minimal overpotentials with a long lifetime. The treatment of cancer requires, novel agents that have potent cytotoxic activity against cancer cells while displaying minimal side effects. In this dissertation the modular synthesis of these bis-thiosemicarbazone systems is utilized to regulate the redox chemistry for employment in the desired sector of chemistry. The ligand and metal chelates synthesized were characterized …


An Evaluation Of The Supply And Demand Of Radiation Oncology Medical Physicists In The United States., Christine Marie Swanson May 2019

An Evaluation Of The Supply And Demand Of Radiation Oncology Medical Physicists In The United States., Christine Marie Swanson

Electronic Theses and Dissertations

Background: This dissertation is a mixed methods evaluation of the radiation oncology medical physics workforce in the United States. Radiation oncology medical physicists serve a vital role in the safe treatment of patients with radiation therapy. While cancer incidence continues to rise, the pathways to board certification in radiation oncology medical physics continue to narrow causing a potential shortage of radiation oncology physicists in the United States. While there is no lack of data about the medical physics community it has scarcely been used to evaluate the current state of the workforce. In order to ensure patient safety, appropriate physics …


Hemoglobin A1c Levels And Sport Participation In Children With Type 1 Diabetes., Amy Kozerski May 2019

Hemoglobin A1c Levels And Sport Participation In Children With Type 1 Diabetes., Amy Kozerski

Electronic Theses and Dissertations

This study’s purpose was to determine a possible difference in hemoglobin A1c levels and sport participation in children with type 1 diabetes. Patients with provided consent via an iPad electronic informed consent/assent (preamble) completed a physical activity and sport participation survey. The survey was linked to their medical chart including demographic and diabetes medical history (e.g. HbA1c). The analyses provided a sample of 120 participants, 40 in the no sport participation group and 78 in the sport participation group with 56 females and 64 males, with an average age12.94±2.8 years. An independent sample t-test, removing one outlier from the …


Innovation And Equity In Public Health Research : Testing Arts-Based Methods For Trauma-Informed, Culturally-Responsive Inquiry., Tasha Golden May 2019

Innovation And Equity In Public Health Research : Testing Arts-Based Methods For Trauma-Informed, Culturally-Responsive Inquiry., Tasha Golden

Electronic Theses and Dissertations

As the field of Public Health has shifted from a biomedical paradigm to a social ecological approach, focusing on health equity and social determinants of health, it has increasingly acknowledged the roles of culture and trauma in health outcomes. The field has responded by modifying some research practices, but continues to prioritize conventional methodologies—with few options designed to foreground trauma- and cultural-responsiveness. Unfortunately, to the extent that conventional approaches require health to be defined, communicated, or valued according to dominant norms, they risk perpetuating inequities. Health equity therefore requires the development of research methodologies that increase inclusivity and access, elicit …


Development Of A Lectin-Fc Fusion Protein With Antiviral And Anti-Cancer Activity., Matthew William Dent May 2019

Development Of A Lectin-Fc Fusion Protein With Antiviral And Anti-Cancer Activity., Matthew William Dent

Electronic Theses and Dissertations

This thesis describes the development of a novel lectin-Fc fusion protein and its antiviral and anti-cancer activity. The molecule, Avaren-Fc (AvFc), is a fusion of a variant of the actinomycete lectin actinohivin (Avaren) and the Fc region of human IgG1, and is selective for the terminal α1,2-mannose residues found at the ends of high-mannose-type glycans that can be found on the surface of certain heavily glycosylated viruses and cancer cells. Here, AvFc was found to be able to neutralize simian immunodeficiency virus as well as Hepatitis C virus with nanomolar IC50 values. Furthermore, AvFc recognizes a number of cell …


The Impact Of Palm Cooling Gloves On Cardiovascular, Thermoregulatory, Metabolic, Perceptual, And Ergogenic Responses Produced From Rowing Ergometry., Ian O'Brien May 2019

The Impact Of Palm Cooling Gloves On Cardiovascular, Thermoregulatory, Metabolic, Perceptual, And Ergogenic Responses Produced From Rowing Ergometry., Ian O'Brien

Electronic Theses and Dissertations

Subjects (n = 34) did three rowing workouts of up to eight 2- minute stages separated by 45-60 second rests. Cardiovascular, ergogenic, thermoregulatory, perceptual and metabolic responses to workouts may be aided by intermittent palm cooling. Subjects received one of the following treatments per workout in a randomized sequence: no palm cooling, intermittent palm cooling during workouts, or palm cooling applied intermittently during workouts and post-exercise recovery. Methods: Palm cooling entailed intermittent cold (8-11o C) against the palmar surface of subject’s hands. Workouts began with 10 minutes of rest, followed by a 10-minute low- intensity warm-up and the workout, concluding …
