Faculty Research ​and Publications

Helicobacter pylori (H. pylori) remains a significant global health concern, affecting nearly half the world’s population and contributing to peptic ulcer disease, gastritis, and gastric cancer. The management of H. pylori infection has evolved over time, with preferred treatment regimens changing due to increasing􀀠antibiotic resistance and the emergence of novel therapies. The American College of Gastroenterology (ACG) recently released its 2024 guidelines, refining the treatment approach to improve eradication rates and reduce antibiotic resistance-related failures.

Assessing The Prevalence Of Ehrlichia Spp. In Ticks Associated With Canids In Arkansas, Eva J. Berryhill

Animal Science Undergraduate Honors Theses

Canine ehrlichiosis is a disease that is commonly seen in dogs. In previous studies, the southeastern part of the United States has been identified as an area of high prevalence. Arkansas was included in the region where the prevalence is high. Changes in climate, household income, and tick population were identified as factors contributing to this high prevalence. Canine ehrlichiosis is caused by three Ehrlichia spp., which are E. canis, E. ewingii, and E. chaffeensis. Ticks are responsible for transmitting the disease, specifically R. sanguineus, D. variabilis, and A. americanum. For this study, the goal was to determine the prevalence …

A Review On Treatment, Prevention, And Research Of Worldwide Parasitic Disease: Toxoplasmosis, Hannah Skinner

All Theses

Toxoplasmosis is a worldwide, yet often overlooked, parasitic disease caused by the protozoan parasite, Toxoplasma gondii. The parasite is capable of infecting humans and almost all warm-blooded vertebrates. Over a million people are infected in the United States with toxoplasmosis each year. Most infections are asymptomatic but severe cases can lead to vision impairment, neurological disorders, and congenital birth defects. T. gondii is transmitted through undercooked meat, infected feline feces, or contaminated water and soil. The burden of T. gondii infection is most notable in livestock, felines, and immunocompromised humans. Despite being a widespread disease, toxoplasmosis is neglected in …

Investigating Fatty Acid Influence On West Nile Virus In Mosquitoes And Birds, Hayley Moree

Honors Program: Senior Projects (Public)

Vector-borne diseases, including Zika virus (ZIKV), Dengue virus (DENV), and West Nile virus (WNV), pose considerable global health threats, accounting for over 400 million infections and more than 700,000 deaths annually. Many vector-borne diseases are within the Flaviviridae family. Despite this, effective treatments have not been found for some flaviviruses. Flaviviruses exploit host cellular machinery to facilitate their replication and survival, reprogramming metabolic pathways, including lipid metabolism. Lipids play essential roles in the viral life cycle, providing structural components for the viral envelope, enabling membrane rearrangements for replication complexes, and supplying energy resources necessary for particle assembly.

Targeting lipid metabolism …

Novel Chloroviruses With Unique Glycans On Their Major Capsid Proteins, Cayden J. Homolka

Honors Program: Senior Projects (Public)

Chloroviruses, of the family Phycodnaviridae, are large, dsDNA viruses with a genome of 290 to 410 kb. These virus genomes are so large that they are classified as “giant viruses”. Within this genome, up to 16 tRNAs and 330 to 450 proteins are encoded. Among the massive amounts of genes and proteins are unique carbohydrate synthesis/metabolism genes, which are responsible for the glycosylation of chloroviruses major capsid proteins. In most viruses, these proteins are glycosylated by the host enzymes located in the endoplasmic reticulum. Instead, Chloroviruses encode their own glycosylation machinery; essentially decorating themselves. Furthermore, these chlorovirus glycans are unlike …

Effects Of Intradermal Injections Of Lipopolysaccharide On The Local And Systemic Acute Inflammatory Responses In Turkeys, Delaney F. Roberts

Poultry Science Undergraduate Honors Theses

In chickens, the growing feather (GF) pulp has been established as a cutaneous bioassay to monitor and assess tissue/cellular immune activities in response to intradermal (i.d.) injections of test materials. The objective of this pilot study was to determine the suitability of the GF bioassay in turkeys by examining the acute inflammatory responses initiated by i.d. GF-pulp injections of lipopolysaccharide (LPS). For this, three, 5-wk-old turkey poults were used. Two poults had 8 GFs injected (10 μL/GF) with low (L)-LPS (0.1 μg/GF) and 8 GFs with high (H)-LPS (1 μg/GF), while a third poult had 8 GFs injected with endotoxin-free …

The Impact Of Public Health Authority On Emergency Response In State Health Departments, Jessica L. Baggett

Dissertations: Doctor of Public Health

Background

Public health authority plays a crucial role in enabling state health officials to implement emergency response measures such as isolation, quarantine, and vaccination campaigns. However, legislative changes following the COVID-19 pandemic have significantly curtailed these authorities in many states, raising concerns about the ability of public health officials to respond effectively to future health crises. The erosion of public health authority has highlighted gaps in the legal literacy of health officials and underscored the need for enhanced training in navigating political and legal challenges.

Purpose

The purpose of this study is to assess legal literacy among state health officials, …

Tennessee Science Teachers’ Views, Challenges, And Practices Addressing Scientific Misinformation In The Science Classroom, Lauren Wilmoth

Ed.D. Dissertations

Scientific misinformation was a major threat to society in the 2020s because individuals often made ill-informed decisions impacting their well-being and the well-being of others. Because of the unique nature of scientific misinformation, key stakeholders advocated for science education to incorporate skills associated with identifying scientific misinformation into science curricula. Despite the call for action, there was little extant research about how high school science teachers addressed and felt about addressing scientific misinformation. Therefore, the purpose of my interpretive qualitative study was to determine Tennessee high school science teachers’ views, challenges, and practices addressing scientific misinformation in the science classroom. …

Clonal Dynamics And Somatic Evolution Of Haematopoiesis In Mouse., Chiraag D Kapadia, Nicholas Williams, Kevin J Dawson, Caroline Watson, Matthew J Yousefzadeh, Duy Le, Kudzai Nyamondo, Sreeya Kodavali, Alex Cagan, Sarah Waldvogel, Xiaoyan Zhang, Josephine De La Fuente, Daniel Leongamornlert, Emily Mitchell, Marcus A Florez, Krzysztof Sosnowski, Rogelio Aguilar, Alejandra Martell, Anna Guzman, David E Harrison, Laura J Niedernhofer, Katherine Y King, Peter J Campbell, Jamie Blundell, Margaret A Goodell, Jyoti Nangalia

Faculty Research 2025

Haematopoietic stem cells maintain blood production throughout life1 . Although extensively characterized using the laboratory mouse, little is known about clonal selection and population dynamics of the haematopoietic stem cell pool during murine ageing. We isolated stem cells and progenitors from young and old mice, identifying 221,890 somatic mutations genome-wide in 1,845 single-cell-derived colonies. Mouse stem cells and progenitors accrue approximately 45 somatic mutations per year, a rate only approximately threefold greater than human progenitors despite the vastly different organismal sizes and lifespans. Phylogenetic patterns show that stem and multipotent progenitor cell pools are established during embryogenesis, after which they …

Low, Michael V. Wiles, David Nemazee, Frode L Jahnsen, John Torgils Vaage, Kenneth A Howard, Inger Sandlie, Leo C James, Gunnveig Grødeland, Fridtjof Lund-Johansen, Jan Terje Andersen

Faculty Research 2025

Although vaccines are usually given intramuscularly, the intranasal delivery route may lead to better mucosal protection and limit the spread of respiratory virus while easing administration and improving vaccine acceptance. The challenge, however, is to achieve delivery across the selective epithelial cell barrier. Here we report on a subunit vaccine platform, in which the antigen is genetically fused to albumin to facilitate FcRn-mediated transport across the mucosal barrier in the presence of adjuvant. Intranasal delivery in conventional and transgenic mouse models induces both systemic and mucosal antigen-specific antibody responses that protect against challenge with SARS-CoV-2 or influenza A. When benchmarked …

Metachronous Periprosthetic Joint Infection In Patients With Multiple Arthroplasties At Index Infection, Devin Young, Daniel Nikolaidis, Andrew Steffensmeier, Robert Runner, Mark Karadsheh

Posters

Periprosthetic joint infection (PJI) is a devastating complication of one of the most successful surgeries in medicine. About 1% to 2% of patients will develop PJI after primary total hip arthroplasty (THA) or primary total knee arthroplasty (TKA) [1]. The 5-year patient survival rate of THA PJI is estimated to be worse than that of common cancers, such as breast cancer [2]. The burden of this disease is likely to increase exponentially as the population ages and the number of patients undergoing total joint arthroplasties increases in the future [3].

Most devastating is what Murray et al deem as metachronous …

Inflammatory Response In Ucd200/206 Scleroderma-Prone Chickens To Intradermal Injection Of Silikon 1000, Katee L. Johnson

Animal Science Undergraduate Honors Theses

Intradermal injections of silicone materials have resulted in chronic inflammation and fibrotic reactions in some individuals. The UCD200/206 line of chickens is characterized by spontaneous development of scleroderma/systemic sclerosis (SSc), a fibrotic autoimmune disease. This longitudinal study examined the cellular inflammatory activity initiated by SILIKON 1000 (a silicone product used as a filler in human skin) at the site of intradermal (i.d.) injection and in the peripheral blood in the SSc-prone UCD 200/206 (UCD) chickens and healthy White Leghorn (WL) controls. Specifically, the pulps of growing feathers (GFs) were i.d. injected with SILIKON or endotoxin-free, sterile PBS (8 and 3 …

The Effect Of 1,25-Dihydroxyvitamin D3 Supplementation On Humoral Immunity Against Bacterial Chondronecrosis With Osteomyelitis Lameness In Broiler Chickens, Bailey Herberger

Animal Science Undergraduate Honors Theses

Bacterial chondronecrosis with osteomyelitis (BCO) lameness, the most predominant locomotive illness in fast-growing broilers, causes substantial animal well-being issues and affects broiler production, leading to huge financial losses. Several strategies, including feed supplementations using organic trace minerals, vitamin D, probiotics, and prebiotics, have been utilized to alleviate BCO lameness incidences in broiler chickens. Previous studies have indicated that feeding an additive of Panbonis^®-G-1,25(OH)₂D₃ from Solanum glaucophyllum containing 1 µg/kg G-1,25(OH)₂D₃ to broilers for the first 28 days of their production cycle reduced BCO lameness by more than 50%. In this study, we …

Who Was Skull #0025336? A Forensic Anthropological Analysis Of Human Remains, Evelyn R. Wendland

Undergraduate Honors Theses

Biological anthropology identifies human remains to learn more about the individual or the ancient community from which they originate. Two subdisciplines of biological Anthropology that focus on osteology—the study of bones— are Forensic Anthropology and Biorchaeology. Forensic anthropology is the study of human remains associated with the legal process. They specifically analyze remains from post-1950. Biorchaeology also looks at human remains but in a historical and/or archaeological context. As osteologists analyze human remains, they typically try to create a biological profile. The biological profile includes classifications of ethnicity (ancestry), age, sex, and stature, as well as aspects of pathology and …

A Tale Of Two Asters: Resolving The Plant And Microbial Community Structure Of An Invasive And Native Forb, William Cartelli

Theses, Dissertations and Culminating Projects

Old fields dominated by flowering forbs are frequent targets for ecological restoration, particularly because they are often inhabited by invasive species whose ecological effects remain context dependent and widely debated. While native plants are typically favored in restoration efforts, and invasive species viewed as threats to biodiversity, such classifications may oversimplify ecological function. This study investigates two dominant genera of the Asteraceae family —Centaurea stoebe (L) (non-native) and Solidago spp. (S. rugosa and S. canadensis, both native)—to examine whether biogeographic origin or ecological strategy more strongly influences their impact on above and below ground community structure. Despite their contrasting origins, …

Comparing Regression Methods To Interpretable Machine Learning In The Prediction Of Infrequent Events In The Social And Psychological Sciences, Brian Lieberman

Theses, Dissertations and Culminating Projects

The following study seeks to answer the question of whether traditional regression models and more complex machine learning models can predict rare and infrequent events in the social and psychological sciences. Part of the study sought to compare the performance of regression models to more complex models, in an effort to determine whether the use of more complex models (which are harder to interpret and configure) is even necessary. This study explored this question via two studies. The first, being a study on workplace misconduct, in which 363 participants in the United States were surveyed as to their workplace experiences …

The Reentry Experience Of Returning Citizens From Prison, Christina M. Kadelski

Theses, Dissertations and Culminating Projects

In 2022, over 1.2 million individuals were housed in federal or state prisons in the U.S., in addition to over 514,000 individuals housed in local jails at mid-year (Bureau of Justice, 2024). As released individuals return to their communities, they face the daunting task of re-integration into the community. The purpose of this study was to identify how returning citizens experience reentry to their communities upon release from prison, their perceptions about their reentry experience, and to learn about their unique responses to the reentry process. This study aimed to explore the experience of these individuals to better understand counseling …

Evaluation Of Human Mesenchymal Stromal Cells (Msc) As An Adjuvant Therapeutic For Chronic Lyme Disease, Matthew Teryek

Rowan-Virtua Research Day

Background: Lyme disease, caused by the spirochetal bacterium Borrelia burgdorferi, is the most prevalent vector-borne illness in the Northern Hemisphere. If undiagnosed or untreated, the disease progresses through multiple stages of increasing clinical severity. While antibiotics such as doxycycline and ceftriaxone are the current standard of care, patients with chronic or late-stage Lyme disease may require additional therapeutic interventions.

Rationale: Human mesenchymal stem cells (MSCs) are of growing clinical interest due to their immunomodulatory properties, low immunogenicity, and potential to promote tissue repair. These characteristics position MSCs as promising adjuvant therapies for chronic Lyme disease, with the potential to …

Igg4-Related Autoimmune Pancreatitis In Patients With Prior Occupational Exposure: A Case Report And Review Of Risks Concerning Blue-Collared Workers, Zachary A. Coren, Justin Le, Jason Tran, Nicholas Moscardelli, Krish Patel, Joshua Coren

Rowan-Virtua Research Day

Autoimmune pancreatitis (AIP), a manifestation of IgG4-related disease (IgG4-RD), is a rare, often misdiagnosed condition that can closely mimic pancreatic cancer, particularly in its clinical and radiographic presentation. We report the case of a 76-year-old retired plumber who presented with painless jaundice and was initially suspected to have pancreatic cancer based on imaging findings. Subsequent endoscopic evaluation, biopsy, and markedly elevated serum IgG4 levels led to a diagnosis of type 1 AIP. Treatment with corticosteroids resulted in rapid clinical improvement and reduction in IgG4 levels, confirming the diagnosis.

This case highlights the diagnostic challenges of AIP, especially among blue-collar workers …

A Ticking Time Bomb: An Overview Of A Case Report Of Neutropenic Fever Secondary To Tick-Borne Illness, Yasemin Galiboglu, Danielle Thor, Joann Ha, Kristine Wong, Cindy Hou

Rowan-Virtua Research Day

The advent of immunomodulatory therapies and their ever-expanding number of treatment indications necessitates the understanding of their associated complications. Neutropenic fever serves as an example of these complications often encountered in clinical practice. Although neutropenic fever can result from virtually any pathogen, episodes of the syndrome secondary to tick-borne illness remain relatively undocumented in the scientific literature. In the case presented, a 77-year-old female with a pertinent past medical history of smoldering IgG multiple myeloma on active immunosuppressive therapy presented with a first-time episode of neutropenic fever likely secondary to tick-borne illness. Through this overview of a broader report, attention …

Case Report: Pigtail Suprapubic Catheter Placement In A Patient With Acute Urinary Retention And Abdominal Mesh, Clara Keum, Zamran Masih, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Acute urinary retention (AUR) is a urological emergency that requires immediate bladder decompression and management of the underlying condition to prevent further complications such as urinary tract infection and renal failure. When standard urethral catheterization is not feasible, a suprapubic catheter can be used to achieve adequate bladder drainage. However, in patients with structural or anatomical challenges, such as the presence of surgical mesh, suprapubic catheter placement can be difficult. This case report presents the successful placement of an 8.5 French pigtail catheter and urinary drainage in an 86-year-old male with abdominal mesh who presented with AUR.

An Unusual Cause Of Sepsis: Capnocytophaga Canimorsus, Capnocytophaga, Christopher Dellmyer, Kishan B. Patel

Rowan-Virtua Research Day

Septic shock can be caused by numerous different pathogens. A few of the more common causes are Streptococcus Pneumoniae, Staphylococcus Aureus, Escherichia Coli, Pseudomonas Aeruginosa, and Candida Albicans. Although these are the pathogens involved in the majority of septic shock cases, it is imperative to take the entire clinical picture into account when treating a patient with septic shock. Here we will discuss a seemingly unimpressive dog bite leading to Capnocytophaga canimorsus bacteremia, septic shock and end organ failure.

Case Report: Haemophilus Influenzae Meningitis In A 65 Year Old Female, Kaywan Saed, Russell Mordecai

Rowan-Virtua Research Day

We report a case of a 65-year-old female who presented with fever, altered mental status, and neck stiffness. Cerebrospinal fluid (CSF) analysis confirmed Haemophilus influenzae meningitis. The differential diagnosis of bacterial meningitis in older adults is broad and includes Streptococcus pneumoniae, Neisseria meningitidis, Listeria monocytogenes, and Haemophilus influenzae. However, in the post-Hib vaccine era, non-typeable H. influenzae has emerged as a significant cause of invasive disease in older adults, particularly in those with underlying comorbidities.

Older patients often present with atypical symptoms, which may delay diagnosis and treatment. In this case, early recognition and prompt administration of empiric antibiotic therapy …

The Impact Of Emergency Room Overcrowding On The Incidence Of Healthcare-Acquired Infections Among Patients, Hayya Ali

Rowan-Virtua Research Day

Emergency department (ED) visits are vital components of healthcare delivery, serving as the primary site for acute medical care, particularly for individuals with urgent medical needs. The ED is among the most crowded hospital units. The fast-paced setting and over-crowdedness of an emergency room have become the reality of every hospital across the United States. Overcrowding causes problems for patients and staff, which include the risk of contracting healthcare-acquired infections. This is due to several factors that in most cases lead to an increase in the number of people within the ED, an increase in mortality and morbidity, and a …
