Study Of The Effects Of Chronic Cadmium Exposure On The Pathogenesis Of Pulmonary Arterial Hypertension., Dakotah Dominique Cathey

Electronic Theses and Dissertations

We reported pulmonary artery hypertension (PAH) patients had elevated levels of Cd in both blood and urine, therefore, this study tested whether Cd directly induces PAH or facilitates PAH pathogenesis in mouse models. C57/6J mice were initially exposed to drinking water with or without 5ppm Cd for 8 weeks. Then, half the mice in both control and Cd groups were given SU5416 and hypoxia (SuHx) for 4 weeks to induce PAH, resulting in 4 subgroups: Control, Cd, PAH, and Cd+PAH. Diastolic and systolic functions of the left and right ventricles (LV, RV) were examined with echocardiography before and after PAH. …

The Interplay Between Lung Adenocarcinoma, Nutrient Availability, And The Microbiome., Alexis A. Vega

Electronic Theses and Dissertations

Lung cancer is one of the most common forms of cancer diagnosed, and has the highest lethality rate across all other forms of cancer in the U.S. While current therapeutic options include chemo-, immuno-, and radio-therapy, the benefits of caloric or nutrient restriction on cancer cells has also been investigated. Due to the many biological functions associated with methionine, many have proposed a methionine restricted diet would lead to favorable outcomes when combating cancer. Although our cells are incapable of synthesizing methionine, the bacteria found in our microbiome can. Furthermore, recent discoveries suggest an independent microbiome found within tumors that …

Genetically Engineering Gingipains For High Yield Large Scale Purification., Andrew E. Fuchs

Electronic Theses and Dissertations

Porphyromonas gingivalis is a keystone oral pathogen in the progression of periodontal disease and has been implicated in the etiology of many other systemic human diseases. P. gingivalis produces primary virulence factors termed the gingipains, a group of cysteine proteases. There is a high demand for high purity gingipains for downstream in vitro studies where P.g. is implicated, both oral and systemic. Gingipain production candidate mutant P.g. strains were generated to isolate each gingipain for large scale purification and the purified gingipains characterized. Two mutants were determined not to be viable for large scale purification of gingipains, each for different …

“I Became Myself”: Exploring Cultural Learning Through Stories And Storytelling., Leah Halliday-Johnson

Electronic Theses and Dissertations

Despite broad acknowledgement in education that culturally responsive teaching is essential to meeting learners’ needs, defining and operationalizing culturally responsive teaching remains a challenge. Along with being designed to meet the needs of students from diverse racial and cultural backgrounds who have traditionally been underserved, one commonly identified feature of culturally responsive teaching is building on students’ cultural assets to promote their learning. And while stories and storytelling are among the most common teaching tools, storytelling pedagogies tend to use stories to deliver content or to assess student learning. This dissertation explores collaborative story sharing as an approach to helping …

Investigating The Effects Of Subchronic Dietary Zinc Supplementation On Diet-Induced Metabolic Dysfunction-Associated Steatotic Liver Disease., Oluwanifemi Esther Bolatimi

Electronic Theses and Dissertations

Zinc deficiency is associated with metabolic dysfunction-associated steatotic liver disease (MASLD). Previous studies show zinc supplementation improves steatosis, but its therapeutic effects in established MASLD remain unclear. We developed a model to characterize the effects of zinc supplementation on high-fat diet (HFD) induced MASLD and hypothesized established MASLD would be attenuated. Mice were fed control diet or HFD for 12 weeks and then grouped into normal or zinc-supplemented diets for 8 additional weeks. At euthanasia, plasma and liver tissues were collected for phenotypic analysis. Twelve weeks of HFD altered glucose clearance and body composition. Eight weeks of subsequent zinc supplementation …

The Impact Of Environmental Pollutants On Alcohol-Associated Liver Disease Pathogenesis., Tyler Charles Gripshover

Electronic Theses and Dissertations

Steatotic liver disease is brought upon by differing etiologies and its global prevalence is expected to keep increasing over the next several decades. Particularly, alcohol-associated liver disease (ALD) manifests from excessive alcohol consumption where the liver retains lipids and progresses with metabolic dysfunction. Previous studies have demonstrated that environmental pollutants, polychlorinated biphenyls (PCBs) promote metabolic dysfunction associated steatotic liver disease (MASLD), in diet-induced obesity models. However, it is unknown if environmental pollutants may also promote ALD pathogenesis. Thus, this dissertation focuses on characterizing the effects of PCB126 in a rodent ALD model followed by multiple ‘Omics approaches to identify mechanisms …

From "Smart Talk" To "Living Well": Commonplaces And Their Role In Narratives Of Rare Disease., Caitlin E. Ray

Electronic Theses and Dissertations

As healthcare becomes more complex, automated, and bureaucratic, patients often suffer from a lack of resources, agency, and visibility when seeking medical care. Rhetoric and Composition, specifically the subfield of Rhetoric of Health and Medicine (RHM), is interested in studying and intervening into such issues. One way to challenge our current understanding of healthcare is to consider how the rare disease patient experience reveals the gaps, limitations, and assumptions of illness and health. I argue here that through rare diseases, rhetoricians of health and medicine can better understand the representation, advocacy, and patient experience within healthcare, and potentially lead to …

A View From Within: Timbre As An Analytical Tool In Contemporary Viola Music, Ash Mach

Electronic Theses and Dissertations

Timbre is an elusive musical parameter that musicians, physicists, and cognitive scientists have been grappling with for centuries. While timbre can roughly be defined as an auditory attribute that distinguishes one tone color from another, this definition does not capture the complexities of sound and our perceptions thereof. Research on timbre has flourished since the 20th century, however, timbre studies has largely gone unnoticed within the viola community. This study, “A View from Within,” helps close the gap between timbre studies and viola repertoire scholarship by presenting analyses of three pieces from the 20th and 21st centuries through a timbre …

Representing The Mixed Plate: Involving Descendant Communities And Kānaka Maoli In Hawai’I Plantation Museums, Amanda Ku’Ualohalanileimakamae Lane

Electronic Theses and Dissertations

This thesis explores the ways that the involvement of diverse stakeholders at Hawai’i plantation museums affects representations of Hawai’i’s plantation history. Plantations in Hawai’i had a direct colonizing effect on Kānaka Maoli (Native Hawaiians), displacing them from their lands, replacing them with immigrant laborers, and putting into motion the chain of events that led to Hawai’i’s annexation in 1898. The current-day population in Hawai’i continues to reflect these significant changes in the society and culture of the islands. Hawai’i’s plantation museums traverse topics of labor, immigration, indentured servitude, and colonization. Simultaneously, these museums advance stories of perseverance, celebration, and multiculturalism. …

Reevaluating The God-Human Relationship Through The Psychological Origin Of Sin: A Comparative Theology Of Schleiermacher And Kierkegaard On The Doctrine Of Sin, Brandon Tsark

Electronic Theses and Dissertations

In his The Concept of Anxiety, Kierkegaard’s decision to have Haufniensis acknowledge Schleiermacher’s contribution to the doctrine of sin continues to raise questions regarding Schleiermacher’s influence on Kierkegaard’s intellectual development. These questions also serve to underscore the general need to locate Kierkegaard properly within the larger context of religious and theological studies in the nineteenth century. Our project here seeks to address these questions with a comparative theology of Schleiermacher and Kierkegaard on the Christian doctrine of sin. I argue that Kierkegaard is right to credit Schleiermacher as a source of inspiration in The Concept of Anxiety because of …

Material Culture In The Mediterranean: An Exploration And Examination Of Anti-Judaic And Antisemitic Spanish Medieval Cultural History, Madison Elizabeth Tarleton

Electronic Theses and Dissertations

Author Gavin Langmuir produced two monographs during his career, both published in 1990. Across both texts, one a proper monograph and one a compilation of essays, he offers a bifurcation of anti-Judaism and antisemitism. These texts illuminate his definitions of the terms and his differentiations on the basis of reason and rationality. Using the bones of these theories, I propose a different kind of bifurcation of these terms as it relates to Mediterranean (medieval) material culture using a cultural historical lens. By applying Gavin Langmuir's theoretical model of nonrational anti-Judaism and irrational antisemitism to material culture, I argue that visual …

Divergence: Toward A Neurodivergent Latinx Liberative Social Ethic, Rudolph P. Reyes Ii

Electronic Theses and Dissertations

A significant problem facing neurodivergent Latinxs is the invisibility of their marginalization and oppression. Neurodivergent Latinxs are invisible in dominant society and theological discourse. While neurodivergence and disability are not synonymous, the failure to recognize the marginalization of disability contributes to neurodivergent invisibility. Disability is depoliticized when disability is conceived as an issue of individual embodiment rather than a social issue of acceptance, accessibility, and equality. Neurodivergent Latinxs are erased, and the physical, epistemic, and institutional violence against them go unnamed.

This research project uses the hermeneutical circle for ethics in formulating praxis in combating the oppression of neurodivergent Latinxs. …

Ex Post Facto Study Of The Effect Of Generational Cohort And Employment Tenure On Employee Satisfaction Of United States Federal Employees, Justin Lee Reed

Electronic Theses and Dissertations

Generational differences and the socialization process within the workplace are often seen as opposing theoretical approaches when attempting to explain or understand employee satisfaction. Generational cohort theory asserts that the perceptions and outlooks developed during an individual’s formative years are based on historical events and location, which become instrumental in how they see and interact with the world around them. Social identity theory asserts that exposure and inclusion into a group or organization creates acceptance for the individual and this assists in structuring their outlook. The purpose of this quantitative ex post facto study was to determine if and to …
