Utilization Of Romosozumab During Covid-19 Pandemic Among U.S. Medicare Beneficiaries, Ye Liu
Utilization Of Romosozumab During Covid-19 Pandemic Among U.S. Medicare Beneficiaries, Ye Liu
All ETDs from UAB
Osteoporosis is increasingly recognized as a major public health issue in the aging U.S. population. Shortly after the licensure of romosozumab, an injectable medication indi-cated for women with postmenopausal osteoporosis at high risk of fracture administered by health care provider monthly, the COVID-19 pandemic broke out, which caused ma-jor disruptions to the delivery of health care across the nation. The pandemic dispropor-tionately affected minority and economically disadvantaged communities, exacerbating many pre-existing health disparities. Romosozumab has the highest dosing frequency among common injectable osteoporosis medications in the U.S. that require an office visit for injection, making romosozumab adherence more susceptible to …
Education Attainment And Health: Outside The Gender Binary, Brianna Patterson
Education Attainment And Health: Outside The Gender Binary, Brianna Patterson
All ETDs from UAB
Transgender and gender nonbinary individuals, hereafter referred to as trans, report worse health outcomes than trans individuals whose gender identity matches their sex assigned at birth, hereafter referred to as cisgender (Bauer, Hammond, Travers et al. 2009, Cicero, Reisner, Merwin et al. 2020). Past research has indicated that social determinants of health, such as education attainment, may be responsible for these inequities (Low 2006, The Lancet Public 2020). Education’s influence on health is well known from previous research, but the association is not distributed equally. In the United States (US) educational system, state and local governments have control, not the …
Genotype And Sex Specific Effects Of Methionine Restriction On The Life And Healthspan Of Drosophila Melanogaster, Joshua Robert Smith
Genotype And Sex Specific Effects Of Methionine Restriction On The Life And Healthspan Of Drosophila Melanogaster, Joshua Robert Smith
All ETDs from UAB
Reduced dietary intake of the amino acid methionine has been reported to significantly extend the lifespan of common laboratory model organisms including Saccharomyces cerevisiae, Mus musculus, and Drosophila melanogaster. Methionine restriction (MR) has also been achieved via non-dietary means such as metabolite supplementation and CRISPR-Cas9 gene editing. MR along with protein and calorie restriction are known as dietary interventions capable of producing pro-longevity benefits through regulation of nutrient sensing pathways. Recent studies in model organisms have also identified beneficial effects of a low methionine diet on aging-associated phenotypes and markers of overall healthspan. However, the effects of this intervention on …

Growing Need For A Standardized Response To Radiopharmaceutical Extravasations, Michael Richard Drelich
Growing Need For A Standardized Response To Radiopharmaceutical Extravasations, Michael Richard Drelich
All ETDs from UAB
Extravasations are medical occurrences where an injected or infused pharmaceutical is unintentionally deposited into the soft tissue near the injection site, rather than into the bloodstream. With radiopharmaceuticals, extravasations can result in potentially large radiation doses to skin and tissue. The current rate of extravasations in clinical settings is estimated to be between 3-23%. In the interest of patient safety, a clearer understanding of the dosimetry and differences in extravasation scenarios to simplify dose estimation is needed. Similarly, the NRC is considering modifying regulations to include extravasations as reportable medical events rather than to continue considering them as patient interventions. …

Investigating The Electrostatics Of Mucins As Key Contributors To Mucus Stasis In Cystic Fibrosis, Elex Skylar Rose
Investigating The Electrostatics Of Mucins As Key Contributors To Mucus Stasis In Cystic Fibrosis, Elex Skylar Rose
All ETDs from UAB
Cystic fibrosis (CF) is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which encodes a channel responsible for the transport of chloride and bicarbonate ions across the apical cell surface. In the respiratory tract, defective CFTR results in viscous and adherent mucus that becomes static within the airway, which leads to chronic infections, progressive lung damage, and early mortality. Historically, CF mucus stasis has been attributed to significant airway dehydration; however, growing evidence has demonstrated that aberrant electrostatic properties of mucins also contribute to mucus stasis in CF. Mucins are large, polymeric glycoproteins …

"Stitched By An Indifferent Hand: Recognizing The Marginal In Cormac Mccarthy's 'Suttree'", Michael Wayne Boody
All ETDs from UAB
For centuries, philosophers have been kept busy by the question of what it means to be recognized. In the early 1990’s the Critical theorist Axel Honneth synthesized ideas put forth by Hegal and George Herbert Mead to propose his theory of Recognition, which suggests that society advances forward when humans exercise moral recognition of each others’ positive attributes; only then can people within society achieve a positive-relation-to-self. While Recognition is not greatly applied to literary theory, I believe that we can use it to explain the main character’s interactions with the people in his community in Cormac McCarthy’s Suttree (1979). …
Environmental Influences On The Physiology Of Cnidarians And Their Symbionts, Shelby Gantt
Environmental Influences On The Physiology Of Cnidarians And Their Symbionts, Shelby Gantt
All ETDs from UAB
Corals and other cnidarians maintain complex symbioses that include photosynthetic endosymbiotic dinoflagellates (Symbiodiniaceae), protozoans, fungi, bacteria, archaea, and other metazoans, collectively known as the holobiont. The stability of these associations is crucial for holobiont resilience and adaptation to environmental conditions and are the results of long-term ecological and evolutionary processes. Environmental factors such as light availability, seasonal environmental fluctuations, and warmer, more acidic conditions can disrupt these symbiotic associations and alter holobiont functioning. To understand the influence of different environments on cnidarian host and symbiont physiology, two framework coral species (Acropora palmata and Orbicella faveolata) from nursery-raised and wild populations …

“Then Let Them Use Us Well”: How The Folger Edition Of Shakespeare’S Othello Limits Sexuality And Character Agency, Ann Elizabeth Mulherin
All ETDs from UAB
Since Shakespeare’s first folio and quartos were initially published directly after his death in the early seventeenth century, various editors have altered his plays for their desired goals. With this in mind, the primary focus of my thesis centers around the Updated Folger edition of The Tragedy of Othello, the Moor of Venice, edited by Barbara Mowat and Paul Werstine, which was published in 2017. The Folger edition repeatedly points out that they have tailored their rendition of Othello to allow modern audiences to understand Shakespeare’s language; they present the intention to accurately and helpfully gloss confusing, antiquated, or significant …

[Mis]Representing “India” And Other Colonial Territories In Donne’S Poetry: An Insight Into Colonialism’S Multifaceted Aspects, Urnisha Dutta
All ETDs from UAB
Colonial objects in Donne’s poems embrace multifaceted attributes, offering diverse reading perspectives. Considering their multifaceted aspects, it becomes impossible for a reader to ignore his poems’ interdisciplinary qualities. They often embrace philosophical, religious, political, and historical connotations. The colonial objects, appearing as “black” characters, silent women, or colonized territories in his poems, generate East-West binaries, Western subject consciousness, Eastern [mis]representations, world polarizations, and color contrasts. His female bodies’ misogynistic/sexual portrayal frequently ends in pulling up colonial references, associating their bodies with colonial landmasses. They often associate with his spiritual consciousness, complicating reading and textual interpretations. Critics thus cannot take a …

A Thematic Analysis Of Health Literacy And Education Disparities Regarding Medical Needs For Transgender Individuals, Rachel Mcmullen
All ETDs from UAB
Transgender individuals experience many challenges within the healthcare system including discrimination, socioeconomic struggles, financial strains, a lack of educated healthcare providers, and a health system framework that makes it even more challenging for them to receive their medical needs (Korpaisarn and Safer). One contributing factor to this lack of education is that on average medical schools in the United States only spend approximately five hours total on the health needs related to lesbian, gay, bisexual, transgender, and queer (LGBTQ) individuals (Miller et al.). Another contributing factor is the stigma around LGBTQ individuals within the medical community. The stigma is concerning …

Filing The Serial Numbers Off: The Role Of The Author In Fanfiction Published As Original Fiction, Lauren Mcinnis
All ETDs from UAB
With the increase of authors altering and publishing fanfiction as original works of fiction, the practices and attitudes of fan communities cross over into the realm of traditional fiction. Throughout its history, fandom is a community built on the shared love of a piece of media or celebrity. The importance of community appears in fanfiction through Author’s Notes and comments sections; both of which traditionally published novels generally lack. When authors choose to make the transition to traditional publication which provides legitimacy that fanfiction lacks, they must remove most of their own identity and the fan-community that they originally relied …

Comparative Enzymatic Analysis Of Different Isoforms Of Group A Streptococcal Bacteriophage H4489a Hyaluronidase, Urvi Prakash Rawal
All ETDs from UAB
The Hyaluronate Lyase derived from Group A streptococcal bacteriophage H4489A gene (HylP) is known for cleaving the glycosidic bonds of high molecular weight hyaluronic acid (HMWHA), a substance often overexpressed in certain types of cancer cells. This enzymatic action produces HA oligosaccharides. Previous research, conducted by our team, has demonstrated that these oligosaccharides play a significant role in reducing the invasion, migration, and proliferation of breast cancer cells. This effect occurs through the disruption of Erk1/2 activation and RhoA expression. This bacteriophage hyaluronate lyase (HylP), a 40kDa protein, possesses a unique collagen-like sequence, consisting of 30 amino acids in a …
