Staphylococcus Aureus Evasion Of The Innate Immune System, James Paul Grayczyk

Dissertations

Upon entry into the host, pathogens must overcome innate immunity in order to cause disease. The innate immune system represents a fast-acting initial line of defense to prevent infection. In order to withstand innate defenses, bacterial pathogens like the Gram-positive bacterium Staphylococcus aureus, produce a wide array of virulence factors that can inhibit innate immune cell recruitment and antimicrobial activity, or directly target and kill phagocytic leukocytes thereby facilitating pathogenesis. Infection with S. aureus can cause disease in virtually any tissue site and is a significant burden to human health. In this dissertation, we sought to understand how S. aureus …

Modulating The Tumor Microenvironment To Induce Cross-Priming For Cancer Immunotherapy, Erica Fleming-Trujillo

Dissertations

Adoptive cell transfer (ACT) using T cells engineered to express tumor-specific T cell receptors (TCR) holds great promise in treating cancer patients. ACT involves the in vitro generation of large numbers of tumor-specific T cells, which are then administered back to the patient, to establish an in vivo response and effective tumor control. Our lab conducted a phase I clinical trial in which metastatic melanoma patients received systemic infusions of autologous T cells transduced to express a tyrosinase-specific TCR (TIL 1383I). We observed tumor regression in one of seven patients and the development of vitiligo, indicative of T cell-mediated killing …

Academic Libraries And Toxic Leadership, Alma C. Ortega

Dissertations

Toxic leadership has yet to be officially recognized as an area of inquiry in the field of library and information studies. Indeed, the literature on academic libraries is only now beginning to address the topic. None of this should be surprising because leadership, in general, continues to be an under-discussed topic in the library and information studies literature.

The topic of leadership, of course, is the central theoretical construct of the leadership studies field, and, in this field, toxic leadership has been systematically studied and discussed. This literature reveals the negative consequences of having a toxic leader as the head …

Liberal Democratic Civic Education And Rampage School Gun Violence: Why We Need An Alternative Theory Of Democracy To Guide Contemporary Civic Education, Samantha Deane

Dissertations

In this dissertation, which relies on philosophical inquiry, I use the case of rampage school gun violence to explore democratic education. Drawing a distinction between liberal-foundational democratic education, which aims to educate the individual on how to become an autonomous rational agent and pragmatic-antifoundational democratic education, which looks to help individuals to understand agency as shared, I argue antifoundational democratic education teaches individuals how to affect their environment and take responsibility for the renewal of their democratic society. Rather than allocating blame in the singular individual, antifoundational democracy teaches citizens how to share the blame, take responsibility for unacceptable violence, …

Aerococcus Urinae: Establishing The Pathogenesis Of An Emerging Uropathogen, Evann E. Hilt

Dissertations

Urinary tract infection (UTI) is the world's most common bacterial infection. Much is known about the infectious process (pathogenesis) of a few of the bacteria that cause these infections, especially E. coli. Unfortunately, the pathogenesis of E. coli and other uropathogenic bacteria was explored almost exclusively in the belief that the bladder is supposed to be sterile. Our recent evidence, however, debunks this dogma. We used modern methods to reveal diverse bacterial communities in the bladders of adult women. These communities differ in women with and without lower urinary tract symptoms (LUTS), including UTI and urinary incontinence (UI). Many bacteria …

Retrieving And Reimagining Sanctuary And Solidarity: Racial Disparities In Infant Mortality, Alyson Capp

Dissertations

In Milwaukee, Black babies die before their first birthday nearly three times as often as White and Hispanic babies. Prematurity is the major cause of infant mortality, and social determinants of health play a large role. Commitments from within Christian bioethical traditions can critique ethical frameworks commonly in use in US bioethics by calling for the incorporation of analysis of social power dynamics that is necessary for addressing this issue. Original ethnographic fieldwork that listens closely to Black mothers and health professionals uncovers key themes related to women's and infant health at the intersection of race, class, and gender. By …

Regulation Of Acetyl Phosphate-Dependent Acetylation And Identification Of Novel Lysine Acetyltransferases In Escherichia Coli, David George Christensen

Dissertations

Over billions of years, organisms have organized chemical reactions into metabolic pathways to sustain life. However, metabolic substrates can undergo many uncatalyzed, extra-metabolic reactions. Acetyl phosphate (AcP), an intermediate of the acetate fermentation pathway in E. coli, is one such metabolite that has been shown to non-enzymatically acetylate hundreds of proteins. This diverse set of targets suggests that acetylation could be a way for the cell to sense its nutritional status and regulate protein activity accordingly. However, how E. coli regulates acetylation, if at all, is unknown.Previous work showed that acetylation becomes pronounced in stationary phase cells. I determined that …

Structure-Guided T Cell Receptor Mutations That Alter Antigen Specificity, Cross-Reactivity, And Polyfunctional Phenotypes In Gene-Modified T Cells, Kendra Foley

Dissertations

Adoptive cell transfer of T cell receptor (TCR) gene-modified T cells targeting specific tumor antigens is currently in clinical trials for patients with advanced malignancies. Despite the clinical responses, there are still hurdles to be overcome in achieving an effective and safe therapy. One of the limitations in the success of this type of therapy is the potential for cross-reactivity and unanticipated off-target reactivity which could lead to autoimmunity. Adverse events encompassing these "off-target, off-tumor" cross-reactivities leading to autoimmunity have been seen in patients in different clinical trials. Here, we demonstrate a novel approach to improve antigen specific reactivity and …

Sources And Atmospheric Oxidation Of Sulfur Dioxide And Formaldehyde Based On Wintertime Aircraft Observations Over The Eastern United States, Jaime R. Green

Dissertations

Plume intercepts from flights on the NSF-C-130 during the Wintertime Investigation of Transport, Emission and Reactivity (WINTER) campaign were used to estimate (1) the oxidation rates of Sulfur Dioxide (SO₂) under wintertime conditions and the factors that determine SO₂ removal; and (2) to examine the oxidation, lifetime and source apportionment of formaldehyde (HCHO). Observations suggest that OH governs the rate SO₂ oxidation in the eastern United States during winter. The range of mean oxidation rates during the day from power plants were 0.22–0.71%/hr, producing SO₂ lifetimes of 13–43 days, if SO₂ consumption is assumed …

Assessing The Temporal Dynamics Of The Lower Urinary Tract Microbiota And The Effects Of Lifestyle, Travis Kyle Price

Dissertations

Urinary tract infections (UTIs) are among the most common bacterial infections in humans, accounting for $3.5 billion in health care expenditures yearly in the United States alone. Yet, treatments for UTI have seen little innovation over the past decade. As demonstrated in other body sites, such as the vagina and gastrointestinal (GI) tract, acute and infectious diseases often have indirect microbial contributions which serve as intriguing new targets for therapies. The recent discovery of the existence of a resident community of bacteria (i.e., microbiota) in the bladders of both women and men, represents a novel avenue for targeting UTIs. However, …

Hierarchical Cluster Analysis: A New Type Of Ranking Criteria Based On Arwu Ranking Data, Zhengshuo Li

Dissertations

The advent of big data leads to many applications of Machine Learning techniques. University rankings is one of the applicable domains, which is currently playing a crucial role in the assessment of the universities' performance. Currently, the rankings are usually carried out by some authoritative ranking institutions by means of weighting techniques and the results are conveyed in numerical rankings. Three of the most famous university ranking institutions have been introduced from a technical perspective. However, these institutions have been proven to be subjective in relation to their data selection and weighting method.

Comparing Defeasible Argumentation And Non-Monotonic Fuzzy Reasoning Methods For A Computational Trust Problem With Wikipedia, Ryan Kirwan

Dissertations

Computational trust is an ever-more present issue with the surge in autonomous agent development. Represented as a defeasible phenomenon, problems associated with computational trust may be solved by the appropriate reasoning methods. This paper compares two types of such methods, Defeasible Argumentation and Non-Monotonic Fuzzy Logic to assess which is more effective at solving a computational trust problem centred around Wikipedia editors. Through the application of these methods with real-data and a set of knowledge-bases, it was found that the Fuzzy Logic approach was statistically significantly better than the Argumentation approach in its inferential capacity.
