The Role Of Histone Deacetylase Complexes In Cardiomyocyes And Heart Diseases, Meimei Wang

All ETDs from UAB

Histone deacetylase complexes play pivotal roles in cardiac biology, however their specific functions in cell fate transitions and adult heart maintenance re-main unclear. We identified the role of HDAC complex in vitro during direct cardiac repro-gramming and in vivo through specific cardiomyocyte deletion of ELMSAN1, a core component of the MiDAC complex. We perform direct cardiac reprogram-ming using a polycistronic construct (hMGT133) expressing MEF2C, GATA4, TBX5, and miR-133. MEF2C expression peaked early, while cardiac markers such as cardiac troponin and α-actinin emerged by Day 9. HDAC1 levels and global histone acetylation (H3K9ac, H3K14ac, H3K27ac) declined over time. An RNAi screen …

Exploring The Influence Of Leadership On The Organizational Performance Of Federally Qualified Health Centers In The United States Through The Lens Of The Upper Echelons Theory, Devdutt Shriram Upadhye

All ETDs from UAB

This study examines the influence that leaders have on the performance of Federally Qualified Health Centers (FQHCs) in the US. The framework through which the study examines this relationship is the Upper Echelons Theory (UET), which posits that managers and leaders take actions that shape the organization they lead, and these actions are based on a confluence of experiential and characteristic factors. The current study focuses on a leader’s influence through three proxies, viz. educational background, role tenure, and sex, on the organizational performance of FQHCs. Performance is captured using both financial and quality metrics. Data for the study was …

Immune And Endothelial Cell Mechanisms Of Cardiovascular And Kidney Disease Risk In Obesity, Claudia Edell

All ETDs from UAB

Obesity is a major risk factor for cardiovascular and chronic kidney disease. Both inflammation and endothelial dysfunction are hallmark signs of adverse health outcomes in obesity. Previous data from our lab has shown that a 2-week time restricted feeding (TRF) intervention reduces kidney CD3+ (T) cells and fibrosis and improves endothelial function in a mouse model of diet induced obesity (DIO). There is little known about kidney damage and T cells in obesity. We hypothesized that TRF reduces kidney damage in obese mice through mitigating T cell inflammation. We use a 20-week DIO model, with 18 weeks of ad libitum …

All ETDs from UAB

Effects of Probiotic Lactobacilli on Streptococcus mutans: Implications for Early Childhood Caries WALAA MOHIEDEN AL TURKI DENTISTRY ABSTRACT Purpose: Probiotic Lactobacillus species have been shown to have beneficial effects against early childhood caries (ECC) by inhibiting the growth of cariogenic bacteria. However, the acidogenicity of Lactobacillus spp. could have potential carcinogenic effect. The objective of this study was to investigate the effects of probiotic lactobacilli and cariogenic lactobacilli on the growth, biofilm formation, and acid production of Streptococcus mutans (S. mutans). Methods: Growth competition between probiotic L. rhamnosus GG (L-GG) or caries-associated L. rhamnosus M72-26 (L-M72) and S. mutans UA159 …

The Role Of The Glycerol Metabolism Regulator Glpr On Pseudomonas Aeruginosa’S Physiology, Nicholas Jordan Evans

All ETDs from UAB

Chronic infections with Pseudomonas aeruginosa are a leading cause of morbidity and mortality in people with cystic fibrosis. P. aeruginosa persists in the CF lung through adaptations, including altering the expression of metabolic genes to acquire nutrients that are abundant in the CF airway. Glycerol in the airway is imported and metabolized by proteins encoded in the glp regulon, which is regulated in part by GlpR. The loss of GlpR was previously shown to increase biofilm development in a P. aeruginosa CF isolate compared to a wound isolate. In the first half of this work, we investigated the influence that …

A Short Trip: A Mixed Methods Investigation Of The Perceived Effects Of Vaporized Dmt Vs Vaporized 5-Meo-Dmt, Cynthia Estrella Ortiz

All ETDs from UAB

The rise in psychedelic use has been accompanied by increased interest in alternative routes of administration, including vaporization. However, little is known about the characteristics and outcomes associated with vaporized forms of N,N-dimethyltryptamine (DMT) and 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT). This mixed-methods study examined the subjective experiences and mental health correlates of individuals who reported using vaporized DMT, vaporized 5-MeO-DMT, or psilocybin mushrooms in the past six months. A total of 209 adults completed an online survey assessing demographic variables, substance use, and psychological functioning, including measures of global health (PROMIS), subjective happiness, magical ideation, spiritual connection, psychosis-like experiences (CAPE-42), and hypomanic symptoms. …

Pao Induces Er Stress In Endothelial Cells Leading To Barrier Function Dysfunction And Inhibition Of Brd4 Prevents Lewisite-Induced Peribronchial Fibrosis, Huaxiu Zeng

All ETDs from UAB

Arsenicals are members of one of the most important global environmental vesicants and are a persistent bio accumulative carcinogen. One of the vesicants and chemical warfare agents is lewisite, which causes lung injury with pulmonary edema, hemorrhage, and respiratory failure. A single cutaneous exposure to lewisite in mice induces systemic lung injury through arsenical-mediated mechanisms. Some subjects develop Bronchiolitis Obliterans Syndrome (BOS) where there is evidence of airway dysfunction and pathologic narrowing of the airways with extracellular protein deposition and fibroblast invasion. In vitro for human lung endothelial cells, Phenyl arsine Oxide (PAO) exposure, as surrogate of lewisite, leads to …

Water Absorption, Surface Roughness And Flexural Strength Assessment Of Peek With And Without Aging., Pranjal Ramchandra Daundakr

All ETDs from UAB

Polymethyl methacrylate (PMMA) has been the primary material for complete denture bases since its introduction in 1936 due to its esthetics, affordability, and ease of processing. However, PMMA demonstrates well-documented shortcomings, including relatively low flexural strength, high water absorption, and susceptibility to surface wear. These limitations lead to fractures, loss of occlusal vertical dimension (OVD), frequent relines, and compromised esthetics. Even advanced formats such as CAD-CAM milled and 3D printed PMMA remain prone to dimensional instability, microbial colonization, and long-term degradation. Polyetheretherketone (PEEK), a high-performance thermoplastic originally used in orthopedic and spinal implants, has recently been introduced into dentistry as …

In-Vitro Antimicrobial Activity, Demineralization Inhibition Potential, And Staining Effects Of Three Silver Fluoride Materials, Quiesly Torres

All ETDs from UAB

Background: Dental caries is a worldwide preventable public health problem. It affects any individuals regardless of their gender, age, ethnicity, and socioeconomic status. Silver diamine fluoride (SDF) has been extensively used for preventing cavities, but it has side effects; therefore, some other biocompatible antimicrobial and remineralization-inducing alternative materials have been developed. Purpose: This study aims to assess the in vitro antimicrobial activity, demineralization inhibition potential, and staining effect of SDF, Nano Silver Fluoride (NSF), and silver fluoride + potassium iodide (SF/KI). Methods: Three silver diamine fluoride-based materials were tested: SDF 38% (Advantage Arrest®, Elevate Oral Care, USA), 1500 ppm NSF …

The Meaning Of Christian Suffering In Aquinas, Pedro Cardoso Figueiredo Santiago

Seton Hall University Dissertations and Theses (ETDs)

This thesis investigates the theological meaning of Christian suffering in the thought of Thomas Aquinas. While much attention has been given to Aquinas’s treatment of the problem of evil, little has been written on the positive and salvific meaning of suffering as it appears in his Christology, sacramental theology, and moral theology. This study aims to demonstrate that for Aquinas, suffering—when united to Christ—acquires a redemptive value that transforms human pain into a means of configuration to the crucified and risen Lord.

The first chapter develops the Christological foundation of Christian suffering. Drawing primarily from Summa Theologiae III, q. 69, …

The Hepatic Glucagon Receptor As A Novel Regulator Of Lifespan, Alexander Tate Lasher

All ETDs from UAB

In developed nations the average lifespan has nearly doubled over the last 200 years, and the proportion of humans living into old age is ever increasing. While this is certainly a testament to the effectiveness of modern medicine and infrastructure, it presents a unique challenge to public health. Gains to health have not necessarily kept pace with the gains in lifespan, and the expanding aged population positions age-associated diseases to reach unprecedented prevalence. In light of this challenge, a mechanistic understanding of the aging process is necessary to identify factors that control longevity and to ultimately develop strategies for healthy …

Interactions Between Staphylococcus Aureus And Corynebacterium Species In The Context Of Chronic Rhinosinusitis, Joshua Tucker Huffines

All ETDs from UAB

Chronic rhinosinusitis (CRS) is a complex inflammatory disease affecting the upper respiratory tract (URT) for a large portion of the populace, leading to significant economic burdens. Staphylococcus aureus is considered as a significant contributor to CRS inflammation through the production of toxins regulated through quorum sensing (QS). Microbiome studies have characterized the microbial communities present in the healthy URT and in CRS. These studies show that the genus Corynebacterium is associated with the healthy URT, decreased in CRS, and has a negative correlation with S. aureus regardless of health status. A few studies have partially characterized a mechanism to explain …

Mechanism Of Targeted Cancer Therapeutics-Induced Cardiotoxicity, Angelica Toro-Cora

All ETDs from UAB

Targeted cancer therapies are known to cause cardiovascular (CV) complications in human patients. Agents such as osimertinib, a tyrosine kinase inhibitor (TKI), as well as immune checkpoint inhibitors (ICIs) have been demonstrated to induce severe cardiotoxicities, including heart failure and myocarditis. Nevertheless, the mechanisms of TKIs and ICIs-induced cardiotoxicity remain poorly understood. Herein, we developed the first in vivo preclinical model of osimertinib-induced cardiotoxicity using a transverse aortic constriction (TAC) mouse model. Osimertinib-treated mice displayed severe cardiac dysfunction, elevated markers of heart failure and fibrosis, and failed to undergo compensatory hypertrophic remodeling, resulting in cardiomyocyte death. Mechanistically, we identified suppression …

Mechanistic Rationale For Toxic Aerosol Formation From Vaping And Dabbing With A Focus On Ketene Formation From Semi-Synthetic Cannabinoids, Kaelas Ryan Munger

Dissertations and Theses

Cannabis vaping is a relatively new route of administration that is increasingly common among youth and young adults. Cannabis vaping has been associated with cases of acute lung injury, especially among youth, and most often involves the heating and aerosolization of high-potency products having cannabinoid concentrations of ~ 50 % - 98 % w/w. Proponents argue that vaping is safer than smoking due to the characteristically lower temperatures and fewer plant materials. However, the extreme cannabinoid concentrations, along with non-natural formulations having undisclosed additives, require studies of the health effects of these products. Despite the popularity of cannabis concentrate vaping, …

How Medical Mistrust Serves As A Barrier To Mental Health Treatment In The African American Community, Nicholas Young

Journal of Social, Behavioral, and Health Sciences

Throughout history, research has depicted the notion that African Americans do not make use of mental health treatment, even when their mental health status may deem it clinically necessary. One of the most prevalent deterrents to African Americans seeking treatment is the mistrust of the medical system. In the African American community, medical mistrust has a longstanding history that stems from the discrimination, racism, lack of representation in the field, and medical mistreatment that African Americans received as test subjects by the medical community over time. Various instances, throughout history, of African Americans being unjustly treated— for the sake of …

Racial Discrimination And Inflammation In Adolescence: Ethnic/Racial Processes As Moderators, Queenisha Crichlow

All ETDs from UAB

Discrimination and other psychosocial stressors contribute to chronic disease by dysregulating neuroendocrine and immune systems, which often leads to increased levels of inflammation. Given that inflammation is a key biological pathway associated with the development of chronic diseases, it has been proposed as a potential mechanism linking racial discrimination to poorer health. Most studies linking racial discrimination with inflammation have focused on adults, despite the fact that children and adolescents also experience discrimination. This dissertation explores the association between racial discrimination and inflammation, measured via salivary C-reactive protein (CRP) and proinflammatory cytokines, among Black and Hispanic adolescents. It also examines …

Identifying The Neurobiological Substrates Of Gulf War Illness, Chloe Lisette Jones

All ETDs from UAB

Gulf War Illness (GWI) affects approximately 30% of veterans who served in the 1991 Persian Gulf War and is characterized by chronic pain and fatigue, as well as cognitive, mood, gastrointestinal, and respiratory symptoms. Animal research has suggested that GWI is caused by a combination of neurotoxicants such as nerve gas, anti-nerve agent pills, and pesticides, though a definitive pathophysiological model has not been established. In this human observational study, 20 veterans with GWI and 20 healthy Gulf War veterans (HV) underwent whole-brain magnetic resonance spectroscopy (MRS) to non-invasively measure several metabolites associated with neuroinflammation. Whole blood was also collected …

A High-Salt Diet Modulates Renal Afferent Nerve Activity; Potential Role Of The Endothelin System, Jiaxi Shen

All ETDs from UAB

Hypertension is a prevalent disease around the world. Increased blood pressure leads to a higher risk of stroke and coronary heart disease. Diet, lifestyle, and gene regulation are potential causative factors, and salt-sensitive hypertension is one common types of hypertension. In response to a high-salt diet, blood pressure may elevate with increasing risks of cardiovascular disease (CVD). Endothelin-1, which binds to endothelin A (ETA) and B (ETB) receptors, is strongly involved in controlling the blood vessels and sensory nerve signaling pathway between the kidney and the central nervous system during high salt dietary challenge. The function of the ETB receptor …

Moving Beyond M1/M2: Xenoline-Polarized Macrophages As A Physiologically Relevant Model Of Tumor-Associated Macrophages In Glioblastoma, Hasan Alrefai

All ETDs from UAB

Glioblastoma (GBM) remains one of the most treatment-refractory cancers, with few therapeutic advances translating into survival benefit. With a median survival of just 15-18 months, the need for effective therapies is urgent. A key obstacle is the underutilization of tumor-associated macrophages (TAMs) in preclinical models. TAMs account for a sizable proportion of GBM by mass and drive malignant behaviors such as angiogenesis, invasion, and resistance to chemoradiotherapy, making them attractive therapeutic targets. Unfortunately, most in vitro GBM-TAM models are inadequate, as they fail to capture the cellular heterogeneity and microenvironmental interactions that drive tumor progression, therapeutic resistance, and immune evasion. …

Probiotic Biogeography In The Neonatal Intestine, Sierra Hansen

All ETDs from UAB

Neonatal infection remains a leading cause of both neonatal morbidity and mortality worldwide, particularly in preterm infants. Probiotic bacteria have been demonstrated to protect against the development of neonatal intestinal dysbiosis, however, formulations and efficacy vary substantially, highlighting a critical gap in the current understanding of the mechanisms governing probiotic efficacy in this population. This gap is exacerbated by regulatory standards which favor economic expansion over scientific rigor. Furthermore, current studies on probiotic efficacy largely rely on indirect or relative readouts of intestinal bacterial burden. Herein, we directly quantify the probiotic effects of Ligilactobacillus murinus V10 and Escherichia coli Nissle …

Structural Basis For Promoter Recognition By Pseudomonas Phage Dev Virion Associated Rna Polymerase, Brittney Bird

All ETDs from UAB

Bacteriophage DEV, a member of the Schitoviridae family, encodes a large virion-associated RNA polymerase (vRNAP) and shows significant potential for use in phage therapy. However, many aspects of DEV’s biology remain poorly understood, especially how it regulates transcription once inside the host. Recent work in our lab suggests that gene product 71 (gp71) functions as a DNA-dependent vRNAP. Analogous to the vRNAP of coliphage N4, gp71 likely initiates transcription by recognizing single-stranded DNA templates that contain early gene hairpin promoters. Based on this, my working hypothesis is that specific interactions between gp71 and the DEV early promoters PE1 and PE5 …

Characterizing The Role Of Pneumococcal Surface Protein A And Humoral Immunity To Biofilm Antigens During Streptococcus Pneumoniae Colonization, Jessica Lane

All ETDs from UAB

Streptococcus pneumoniae (Spn), or “the pneumococcus”, is a Gram-positive bacterium that colonizes the upper respiratory tract as a pathobiont. Spn is a deadly human pathogen, and one of the leading etiological agents of community-acquired pneumonia (CAP). One virulence factor of Spn is pneumococcal surface protein A (PspA), a choline-binding protein (CBP) at the surface of the bacteria that interacts with the host environment. Here, we demonstrated a novel role for PspA involving adhesion to dying host nasal epithelial cells via a multimeric complex with host lactoferrin (LF) and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). We found that the PspA-GAPDH complex aggregated the bacteria …

Understanding Clinical Tool Adoption In Primary Care: A Case Study Of The Cmds Care Pathway, Khushbu Khatri Park

All ETDs from UAB

The rising prevalence of obesity, diabetes, and cardiovascular disease (CVD) places increasing strain on healthcare systems and primary care providers (PCPs). In response, the University of Alabama at Birmingham (UAB) adapted the Cardiometabolic Disease Staging System (CMDS), a validated clinical decision support tool, designed to stratify patient risk and guide evidence-based treatment. Embedded within the electronic health record (EHR) as a Care Pathway, the CMDS was designed for real-time use during primary care visits. This dissertation examines utilization of the CMDS in a two-phase case study, guided by the Adult Learning Theory, Group Dynamics Theory, Force Field Theory and Change …

The Association Of Resilience Factors With Mental Health Outcomes Among Middle-Aged And Older People Living With Hiv, Jeremy Delgadillo

All ETDs from UAB

Research suggests that people living with HIV (PLWH), an aging chronic health population, have higher prevalence rates and severity of mental health and substance use disorders compared to people living without HIV (PLWoH). Cross-sectional and longitu-dinal studies have suggested intrapersonal resilience factors may serve a protective function in reducing the prevalence and severity of mental health and substance use outcomes among PLWH. The purpose of the current study was two-fold. The first aim was to systematically review the current state of the literature from 2000 to present that examined the associations between intrapersonal resilience factors and mental health outcomes among …

Influenza A Virus Increases Susceptibility To Streptococcus Pneumoniae By Damaging The Airway Epithelium, Erin Yepsen Earnhardt

All ETDs from UAB

Influenza A Virus (IAV) is commonly complicated by secondary bacterial infections with Streptococcus pneumoniae (Spn), leading to increased morbidity and mortality. Recent work from our lab demonstrates that an IAV-induced loss of cystic fibrosis transmembrane conductance regulator (CFTR) in the airway disrupts the rheostatic properties of the airway surface liquid (ASL). In cystic fibrosis, caused by mutations in the CFTR gene, there is an increase in the bacterial burden of the airway. However, the underlying mechanisms and damage caused by IAV-induced CFTR dysfunction in the airway remains unknown. Using a primary differentiated human bronchial airway epithelial cell culture (HBEC) system, …

Lineage-Associated Zinc Metalloprotease B And Its Impact On Cardiac Damage Elicited During Invasive Pneumococcal Disease, Jennifer Nichelle Luck

All ETDs from UAB

During invasive disease, certain strains of Streptococcus pneumoniae (Spn) can invade the myocardium, damaging cardiomyocytes and predisposing patients to life-threatening cardiac complications. To identify genetic loci involved in pneumococcal cardio-virulence, we performed a bacterial genome-wide association study using 825 genomes corresponding to 17 distinct Spn lineages associated with varying rates of cardiac complications during hospitalization for pneumonia. This led to the identification of an allele of zmpB, the gene encoding Zinc metalloprotease B (ZmpB). Infection of mice with a ZmpB deficient mutant, i.e., TIGR4ΔzmpB, found that ZmpB was required to form foci of infection in the heart, i.e., cardiac microlesions. …
