The use of rhetoric can be a powerful tool to persuade individuals. Politicians are no stranger to using this tool and often employ it when speaking to their constituents. One politician who utilized his own forms of rhetoric is former President Ronald Reagan. Reagan used rhetoric to discuss major issues with the American public, including the AIDS epidemic. This thesis analyzes Reagan and his administration’s use of rhetoric regarding the AIDS epidemic in order to answer the research question: How did the Reagan administration’s use of rhetoric further marginalize the risk groups associated with the AIDS epidemic? Although previous literature …


The Diversity And Evolution Of Phenazine Biosynthesis Pathways In Enterobacterales, Christian Leise May 2021

The Diversity And Evolution Of Phenazine Biosynthesis Pathways In Enterobacterales, Christian Leise

Honors Theses

Enterobacterales is an order of Gram-negative bacteria that encompasses plant and animal pathogens and organisms of industrial importance. Some of these bacteria produce secondary metabolites classified as phenazines (Phz). Studies in other groups of microorganisms revealed that phenazines are redox-active and exhibit broad antibacterial, antifungal, and antiparasitic activity. Enterobacterales are known to produce phenazines, but details about the diversity, biochemistry, and function of phenazine metabolites in these organisms are missing. In this work, we screened the National Center for Biotechnology Information (NCBI) GenBank for genome sequences of phenazine-producing (Phz+) Enterobacterales. Additionally, genomes of Phz+ strains Pectobacterium carotovorum cc303 and …

The Impact Of Oxygen Availability And Oxidative Stress On Regulation Of Cyclic-Dimeric-Gmp In Listeria Monocytogenes Strain F2365, Anna G. Welch

Honors Theses

Listeria monocytogenes is a gram-positive foodborne pathogen that results in the infectious disease listeriosis. The second messenger molecule cyclic-dimeric-GMP has been found to be responsible for the regulation of expression of many of its virulence factors with diguanylate cyclases and phosphodiesterases regulating the intracellular concentration of cyclic-di-GMP through synthesis and degradation, respectively. This study investigated the possibility that the availability of oxygen is the environmental signal crucial to the regulation of these enzymes. Prior research in our laboratory has demonstrated that the intracellular concentration of cyclic-di-GMP is elevated when exposed to anaerobic conditions. Due to this, it was hypothesized that …


Study Of The Role Of The Msaabcr Operon In Tricarboxylic Acid Cycle Activity And Persister Cell Formation In Staphylococcus Aureus, Karsen Motter May 2021

Study Of The Role Of The Msaabcr Operon In Tricarboxylic Acid Cycle Activity And Persister Cell Formation In Staphylococcus Aureus, Karsen Motter

Honors Theses

Staphylococcus aureus is an important human pathogen that causes wide arrays of infections ranging from minor skin infections to lethal systemic conditions such as infective endocarditis, osteomyelitis, sepsis and pneumonia. These systemic diseases are often difficult to treat due to the presence of persister cells. Persister cells are a phenotypic variant of the bacterial population that exhibit extreme and transient antibiotic tolerance accompanied by a transient halt in growth. Upon cessation of antibiotic treatment, however, persisters resume growth which results in recurrence of infections. This characteristic of persister cells therefore displays high clinical significance. In this study, we show the …

Determine The Effects Of Propionate On The Interactions Between Macrophages And Listeria Monocytogenes, Stephanie M. Johnson May 2021

Determine The Effects Of Propionate On The Interactions Between Macrophages And Listeria Monocytogenes, Stephanie M. Johnson

Honors Theses

Listeria monocytogenes is an opportunistic and intracellular foodborne pathogen that can be deadly in high risk populations. During infection in the human body, L. monocytogenes may encounter macrophages, a type of white blood cell that is critical in innate immune response both by directly targeting invading pathogens and by eliciting adaptive immune responses. During intestinal as well as peripheral infections, both L. monocytogenes and macrophages may encounter propionate, a common gut microbiome metabolite. Although propionate is shown to have various regulatory and nutritional functions, its effects on infection outcome is not well understood. Therefore, the goal of this research is …

Research shows that adapting existing buildings to the WELL Building Standard improves air quality, promotes clean contact, and strengthens immune systems (The International WELL Building Institute, 2020). Additionally, adapting existing historic structures maintains cultural significance within the community. This thesis creates a hypothetical adaptive reuse plan for adapting Engel Stadium in Chattanooga, Tennessee into Engel Concourse, a gathering place for students, UTC faculty, and community …


Being Female And Indigenous: Barriers To Reducing Bolivia's Maternal Mortality Rates Under Evo Morales, Channell Cole May 2021

Being Female And Indigenous: Barriers To Reducing Bolivia's Maternal Mortality Rates Under Evo Morales, Channell Cole

Honors Theses

This thesis seeks to answer the question: What are the barriers to attempts to reduce Bolivia’s maternal mortality rate under Evo Morales? While Morales’ presidency began in 2006, the timeline is from 2004 to the present to account for changes due to his policy. Using activity theory and social capital theory, I argue that machismo and racism are two social factors that are barriers to efforts to reduce the maternal mortality rate. Machismo manifests itself uniquely in Bolivia, as I argue through a comparison to Paraguay. Machismo is also riddled with a history of anti-indigenous racism. I examine the Rockefeller …

Overdose Prevention Sites Placement Informed By Simulation, Jing Dong Apr 2021

Overdose Prevention Sites Placement Informed By Simulation, Jing Dong

Honors Theses

In Philadelphia, people are experiencing the greatest opioid crisis in a century. Plac- ing the Overdose Prevention Site (OPS) can alleviate this crisis. However, the journey to the successful launch of the first OPS in the USA is rough. It was first accused of having a collision with federal drug laws. While Safehouse won the lawsuit and the OPS was judged to be legal in 2020, other pressure rose afterward such as the against from the public and the COVID19, which delayed the plan to open the OPS. Without solid research on the effectiveness of OPS, we thought it is …


Art And Aids: Viral Strategies For Visibility, Stephen Baylor Pillow Apr 2021

Art And Aids: Viral Strategies For Visibility, Stephen Baylor Pillow

Honors Theses

“Art & AIDS: Viral Strategies for Visibility” examines the complex relationships between social stigma, healthcare, homophobia, and mortality, and how these impacted the lives of Western artists and manifested in their works. Most of the art discussed in this thesis was produced during the height of the AIDS crisis (late-1980s to mid-1990s). During this period, gay artists and their allies employed new strategies in their work to inspire activism, and convey intense emotions –– predominantly frustration, grief, and anxiety –– associated with HIV/AIDS. In the U.S., the inaction of the Reagan administration was largely due to widespread homophobia kindled by …


Potential Interactions Between Gper1 And Hiv Tat-Mediated Neurotoxicity, Shiwani Thapa Apr 2021

Potential Interactions Between Gper1 And Hiv Tat-Mediated Neurotoxicity, Shiwani Thapa

Honors Theses

Great advances have been made in the treatment of HIV, however, new infections remain consistent each year with no effective cure. The early entry of HIV virus into the central nervous system is thought to contribute to the development of HIV-associated neurocognitive disorders. One of the mechanisms of neurological impairment may involve actions of the neurotoxic HIV viral protein, trans-activator of transcription (Tat). Tat can be secreted from infected cells and acts as an excitotoxin, increasing the intracellular flux of Ca2+ , promoting mitochondrial dysfunction, and neural cell damage/death. Previous experiments have shown that steroid hormones such as estrogen can …

Xenophobia In The Covid-19 Era, Joanne Jeya Apr 2021

Xenophobia In The Covid-19 Era, Joanne Jeya

Honors Theses

COVID-19 has altered people's daily lives across the globe and heightened tensions in response to changing economic, social, and political conditions. In the United States, xenophobia has seemingly escalated in the COVID-19 era, particularly towards Asians and people of Asian descent. The assumed reasoning for this rise in anti-Asian sentiment is tied to the presumed origins of the Severe Acute Respiratory Syndrome‐Coronavirus‐2 (SARS-CoV-2) virus, first detected in Wuhan, China, prompting some to initially call the disease the Wuhan or Chinese virus, among other racialized terms like the "Kung-flu." It remains to be seen if xenophobic acts have increased throughout the …

The Relationship Between Glucocorticoids And The Humoral Immune Response To Mycoplasma Gallisepticum Challenges In Eastern Bluebirds, Joshua Smith May 2020

The Relationship Between Glucocorticoids And The Humoral Immune Response To Mycoplasma Gallisepticum Challenges In Eastern Bluebirds, Joshua Smith

Honors Theses

Numerous studies have examined relationships between adrenal glucocorticoids and the immune system’s ability to fight disease. The relationship can vary, with glucocorticoids having either stimulatory or inhibitory effects. The pathogenic bacterium Mycoplasma gallisepticum (MG) elicits an adaptive immune response in birds, in which B cells produce MG-specific antibodies to fight the infection and prevent reoccurrence. Previous research found that Eastern Bluebirds that produce the most antibodies in response to MG infection also have the highest glucocorticoid levels. This finding led to the current study investigating whether corticosterone, the primary glucocorticoid in birds, stimulates production of antibodies in response to immune …
