Exploring Spike-Dependent And Ace2-Independent Sars-Cov-2 Interactions With Salivary Epithelial Cells In The Absence Of Ace2, Caitlynn M L Barrows, Thaise C Geremias, Simon Young, Mary C Farach-Carson

Faculty, Staff and Student Publications

Salivary gland infection by SARS-CoV-2 requires viral entry via routes and mechanisms that remain unresolved. This study examined the expression of the angiotensin-converting enzyme 2 (ACE2) receptor in salivary tissues and basal cell-derived human salivary progenitor cells (hS/PCs), an unstudied potential entry point for SARS-CoV-2. Multiple detection modalities, including immunocytochemistry, Western blotting, flow cytometry and RT-PCR, demonstrated a consistent lack of ACE2 protein and transcript in both tissue specimens and primary salivary epithelial cells. Antigen retrieval at pH 9 was determined to be optimal for immunodetection protocols, yet ACE2 remained undetectable. Small intestine tissue served as a positive control, confirming …

Pre-Chiropractic Student Organization At The University Of Mississippi: Education Of Future Chiropractic Students And Empowerment Of The Public With Chiropractic Knowledge, Avery E. Lirette

Honors Theses

The chiropractic profession continues to grow within the allied health community, yet public understanding of its scope remains limited. Prior to the creation of the Pre-Chiropractic Student Organization (PCSO) at The University of Mississippi, students interested in pursuing chiropractic education lacked a structured support system in comparison to those available for other health professions on campus. This thesis documents the foundation, development, and impact of the PCSO as a registered student organization that was designed to educate undergraduate students about the chiropractic profession, connect them with mentors and graduate programs, and promote public awareness of chiropractic care.

Hierarchical Small Molecule Inhibition Of Myst Acetyltransferases, Xuemin Chen, Alexandra Castroverde, Minervo Perez, Ronald Holewinski, Kiall F Suazo, Rashmi Karki, Thorkell Andresson, Benjamin A Garcia, Jordan L Meier

2020-Current year OA Pubs

MYST lysine acetyltransferases (KATs) are a class of epigenetic enzymes critical for cellular function that constitute an emerging therapeutic target in cancer. Recently, several drug-like MYST inhibitors have been reported that show promise in preclinical models as well as in clinical trials of breast cancer. Understanding the specificity of these molecules is critical for their effective use as chemical probes. Here we apply an integrated profiling strategy to systematically define the potency and selectivity of drug-like MYST KAT inhibitors. First, we use optimized chemoproteomic profiling and histone acetylation biormarkers to study the industry-developed KAT inhibitor PF-9363. This reveals dose-dependent engagement …

Assessment Of Platelet Activation In Dogs With Naturally Occurring Acute Pancreatitis, Guhyun Kwon, Seulgi Bae

The Thai Journal of Veterinary Medicine

Recent studies have demonstrated that platelets are crucial in inflammation and immune responses. Alteration in platelet activity impact morbidity and survival due to the formation of intravascular clots or bleeding resulting from impaired platelet function. Aiming to evaluate changes in platelet activity in dogs with naturally occurring acute pancreatitis (AP), we identified differences in quantitative and morphological platelet indices, as well as the ratio of platelets expressing P-selectin on their surface (activated platelet ratio; APR) between dogs with naturally occurring AP and healthy dogs. The study included 9 client-owned dogs with AP (the AP group) and 28 client-owned healthy dogs …

Journal of Community Hospital Internal Medicine Perspectives

This case report underscores the critical interplay between adrenal crisis and seizure activity, emphasizing the importance of rapid recognition and management of this life-threatening condition. Adrenal crisis, characterized by severe hypotension and electrolyte disturbances, often manifests with nonspecific symptoms such as fatigue, nausea, and altered consciousness, which can obscure diagnosis, especially in pediatric and young adult populations. The report details a 21-year-old female with a complex endocrinologic background who developed seizures precipitated by an adrenal crisis triggered by gastroenteritis and compounded by medication noncompliance. Clinical findings included profound dehydration, electrolyte abnormalities, refractory hypotension, and low cortisol levels, which responded favorably …

H2ax C-Terminal Dipeptide Truncation: A Master Switch Of The Dna Damage Response, Faith M Joseph, Matthew V Holt, John M Jerome, Linda Zhang, Ashley G Boice, Patricia D Castro, Sofía I Aramburu, Ruhee Dere, Susan M Rosenberg, David R Rowley, Nicolas L Young

Faculty, Staff and Students Publications

Phosphorylation of histone H2AX at serine 139 (γH2AX) by ATM/ATR kinases is a central marker of the DNA damage response (DDR), widely used to detect DNA double-strand breaks. However, the molecular basis for tissue- and context-specific variation in γH2AX signaling remains poorly defined. Here we discover a post-translational truncation of H2AX, catalyzed by lysine demethylase 4A (KDM4A), which removes two C-terminal amino acids critical for ATM/ATR-dependent phosphorylation. This truncation renders H2AX refractory to γH2AX formation, effectively bypassing canonical DDR signaling. Truncated H2AX accumulates in select cell lines, primary cells, solid tumors, and normal tissues. Genetic knockdown or pharmacologic inhibition of …

Care, Control, And The Racial Regulation Of Black Women’S Reproduction In American Medicine, Rheya K. Wilk

Honors Thesis

Black women in the United States continue to experience disproportionately high rates of maternal mortality, negative reproductive healthcare experiences, and documented disparities in medical treatment. From slavery through the twenty-first century, American medicine has repeatedly positioned Black women’s reproduction as a site of regulation, rather than care, making medical mistrust among Black women a rational response to a long history of institutional conflict embedded in American medicine. Drawing on medical history and bioethical analysis, this thesis traces reproductive abuse across distinct, yet connected, eras. Beginning with antebellum gynecological experimentation on enslaved women, it demonstrates how racialized assumptions about pain and …

"First, Do No Harm": Ethical Failures And Preventive Solutions In The United States Pharmaceutical System - A Narrative Review, Rebekah R. Bailey

Honors Theses

The United States pharmaceutical system is highly advanced but faces growing ethical concerns related to drug development and marketing, overprescription, and high drug costs. This thesis examines how pharmaceutical marketing, regulatory practices, and prescribing behaviors may conflict with the ethical principle of “first, do no harm.”

Using a narrative review of interdisciplinary literature in public health, medical ethics, and applied ethics, this thesis analyzes patterns in drug development, marketing strategies, and regulatory oversight. The findings suggest that ethical issues are systemic, driven by commercial incentives, inconsistent regulatory standards, and an increasing reliance on pharmaceutical solutions. These factors contribute to overmedicalization, …

A History Of Native Medical Auxiliaries, Tanzania:1920s To The 1960s, Irene Gabriel Ndosi, Ashura Jackson Ngoya

Journal of Humanities and Social Sciences

This paper examines the role and evolution of Native Medical Auxiliaries (NMAs) in Kilimanjaro, Tanzania, during British colonial rule between the 1920s and 1960s. It argues that NMAs were not merely subordinates within the colonial medical system but active agents who negotiated and blended Western medical practices with indigenous healing knowledge. Drawing on archival records and oral histories, the paper finds that NMAs filled critical gaps in healthcare delivery, particularly in rural areas, while simultaneously preserving local therapeutic traditions. By applying Local Agency Theory, the paper highlights the NMAs’ strategic engagement with colonial structures and their contribution to shaping hybrid …

Expanding Expanded Access: A Case Of Onc201 And The Ethical Limitations Of Compassionate Use, Ava C. Hutchings

Honors Theses

This study examines the ethical and structural limitations of the Expanded Access program in the United States, with particular focus on its application to terminal pediatric illness. Although the program is intended to provide patients with life-threatening conditions access to investigational therapies outside of clinical trials, its effectiveness in serving critically ill children remains uncertain. This program is analyzed through careful consideration of regulatory review and ethical theory. Key policies governing Expanded Access are examined alongside scholarly discussions of pediatric autonomy and parental authority.

A case study of ONC201, a now-approved investigational drug, is used to illustrate how Expanded Access …

Values-Based Clinical Ethics: A New Model Of Health And Ethics Consultation For Patients Suffering In Extremis, Adam Trainer

Electronic Theses and Dissertations

This dissertation argues that contemporary clinical ethics is inadequately equipped to support patients suffering in extremis because it relies on an insufficiently discriminating account of health and a constrained model of moral reasoning. Drawing on Bernard Lonergan, it reconceives health as an emergent, multi-layered, heuristic notion shaped by biological, psychological, social, and existential goods. On that basis, it critiques principlism’s global applicability thesis and the undergirding claim that its principles form part of the common morality, arguing that this justificatory structure is philosophically insufficient and practically limited for clinical ethics in cases marked by profound suffering, moral plurality, and normative …

Progressive Cardiac Phenotypes And Reduced Reversibility From Long-Term Cugexp Rna Expression In A Dm1 Mouse Model, Rong-Chi Hu, Mohammadreza Tabary, Xander Ht Wehrens, Thomas A Cooper

Faculty, Staff and Students Publications

Myotonic dystrophy type 1 (DM1) is caused by an expanded CTG repeat in the DMPK gene, resulting in mutant transcripts that form expanded CUG (CUGexp) RNA foci and sequester muscleblind-like (MBNL) RNA-binding proteins. DM1 is multisystemic, with progressive worsening of disease manifestations in affected tissues. Disease progression is attributed to somatic expansion of the CTG repeats with age, resulting in production of CUGexp RNA with enhanced intrinsic toxicity due to increased MBNL sequestration. To determine the degree to which cardiac disease progression can occur independently of repeat expansion, we used a transgenic DM1 mouse model with inducible heart-specific expression of …

Identifying Novel Gene Dysregulation Associated With Opioid Overdose Death: A Meta-Analysis Of Differential Gene Expression In Human Prefrontal Cortex, Javan K Carter, Bryan C Quach, Caryn Willis, Melyssa S Minto, Dana B Hancock, Janitza Montalvo-Ortiz, Olivia Corradin, Ryan W Logan, Consuelo Walss-Bass, Brion S Maher, Eric Otto Johnson

Faculty, Staff and Student Publications

Only recently have human postmortem brain studies of differential gene expression (DGE) associated with opioid overdose death (OOD) been published; sample sizes from these studies have been modest (N = 40-153). To increase statistical power to identify OOD-associated genes, we leveraged human prefrontal cortex RNA-seq data from four independent OOD studies and conducted a transcriptome-wide DGE meta-analysis (N = 272). Using a unified gene expression data processing and analysis framework across studies, we meta-analyzed 20, 098 genes and found 335 significant differentially expressed genes (DEGs) by OOD status (false discovery rate <  0.05). Of these, 66 DEGs were among the list of 303 genes reported as OOD-associated in prior prefrontal cortex molecular studies (e.g., genes/gene families OPRK1, NPAS4, DUSP, EGR). The remaining 269 DEGs were not previously reported (e.g., NR4A2, SYT1, HCRTR2, BDNF). There was little evidence of genetic drivers for the observed differences in gene expression between opioid addiction cases and controls. Enrichment analyses for the DEGs across molecular pathway and biological process databases highlight an interconnected set of genes and pathways linked to orexin and tyrosine kinase receptors through MEK/ERK/MAPK signaling to affect neuronal plasticity.

The Ethical Imperative Of Public Health Institutions To Protect The Reproductive Autonomy Of Vulnerable Populations, Kennethea Wilson

Electronic Theses and Dissertations

This dissertation establishes the ethical responsibility of public health institutions to safeguard reproductive autonomy, especially among vulnerable populations. While reproductive decision-making is traditionally framed within individual clinical encounters, this work contends that reproductive autonomy is fundamentally a matter of public health ethics. Socioecological determinants, including social, legal, environmental, and structural factors, often constrain individuals’ ability to make meaningful reproductive choices, leading to preventable harm.

Reproductive autonomy is defined as the capacity to make informed decisions about whether and when to conceive, as well as how to parent. The dissertation critiques the sufficiency of clinical ethics frameworks, such as informed consent …

Multi-Site Dms Probing Reveals Higher-Order Structure Of Rna-Protein Complexes In Living Cells, Irfana Saleem, Thomas Miller, Lucas Kearns, Anthony Hoang, Joshua Meehan, Ritwika Bose, David Mitchell, David H Price, Calla M Olson, Chase A Weidmann, Anthony M Mustoe

Faculty, Staff and Students Publications

Identifying tertiary structures and protein binding sites in RNA molecules remains a key challenge in RNA biology. We describe multi-site dimethyl sulfate (DMS)-mutational profiling (MaP) (msDMS-MaP), a strategy that enables simultaneous measurement of RNA secondary, tertiary, and quaternary structures via a single DMS chemical probing experiment. Optimized reverse transcription decodes typically invisible DMS N7-methylguanine (N7-G) modifications via a tautomer-induced mutational signature concurrent with N1 and N3 modifications. We show that N7-G reactivity reports on higher-order RNA structures, revealing key functional motifs such as pseudoknots and protein binding sites. Using msDMS-MaP, we find that E. coli ribosomal RNAs encode numerous independently …

Neuroprotective Effects Of Estradiol And Genistein And Interactions With Aromatase Inhibitions Post Cerebellar Lesion In Male Zebra Finches, Grace E. Thompson, Anthony P. Irovic

Honors Theses

Across vertebrates, peripheral and brain-derived estradiol (E₂) promotes neuroplasticity. After injury, E₂ can be derived locally from testosterone via aromatase (AROM), an enzyme that is upregulated in glia at the site of neural injury. E₂disrupts testicular function and elevates cancer and stroke risk, primarily via binding to estrogen receptor alpha (ER α). Genistein (GEN), a phytoestrogen, is similar to E₂ but binds preferentially to estrogen receptor beta (ER β). It may offer neuroprotection without adverse effects of E₂. We used adult male zebra finches (ZF) to model neuroprotective effects of E_{2 …}

Rational Design And Efficacy Evaluation Of A Novel Solid Dispersion-Based Bempedoic Acid–Ezetimibe Fixed-Dose Combination Tablet Versus Nexlizet®, Mohamed A. Heikal, Wael Ali, Mahmoud A. Mahdy, Eman Gomaa

Nanotechnology Research Centre

Background/Objectives: For hyperlipidemic patients with statin resistance, a fixed-dose combination of a non-statin drug such as ezetimibe (EZT) and bempedoic acid (BA) provides a significant benefit. Although both drugs exhibit poor aqueous solubility, the oral bioavailability of EZT is more critically limited by dissolution, whereas BA maintains adequate absorption due to its high intestinal permeability. With regard to the reference product, Nexlizet® (180/10 mg), our study focused on developing a novel tablet with superior in vitro performance without incorporating sodium lauryl sulfate (SLS), as it may potentially alter BA absorption. Methods: The solid dispersion technique (co-precipitation) was applied using the …

The Intersection Of Faculty Perceptions Of Student Evaluations Of Teaching And Nursing Retention: The Challenges Of Undergraduate Nursing Programs In Higher Education Institutions, Melissa Wolff

Dissertations, Theses, and Projects

For over 100 years, higher education institutions in the United States of America have been using student evaluations of teaching (SET) to evaluate course effectiveness and teaching quality. SETs are used to inform faculty about areas where course improvements are needed, if course objectives have been met, and the strength of their teaching ability. Even with the longstanding integration of SETs in higher education their reliability and validity have been questioned. Various factors negatively influence student ranking of faculty including class size, faculty appearance, ethnicity, and gender. SETs also impact faculty’s ability to earn tenure and promotion, which raises concerns …

Involuntary Medication Administration Review: A Historical Look At New Jersey Psychiatric Law And Its Significance, Casey Burke, Joon Min Chun D.O., Ramya Kommidi D.O., Salvatore Montana Messina D.O.

Rowan-Virtua Research Day

The legal and ethical evolution of involuntary psychiatric medication in New Jersey has been shaped through the landmark legal cases Rennie v. Klein and Brandt v. Monte. To this effect, this poster explores how each case shaped state hospital policy and the balance between patient autonomy and clinical judgment. Rennie v. Klein (1978) established a constitutional right for involuntarily committed patients to refuse psychotropic medication, except in emergencies or with due process safeguards. Decades later, Brandt v. Monte (2006) exposed flaws in New Jersey’s administrative procedures—particularly Administrative Bulletin 78-3—which permitted coercive practices under the guise of emergency treatment and lacked …
