Disrupted Circadian Rhythms Affect Hallmark Pathologies In Alzheimer’S Disease-Related Mouse Models, Valeria Buzinova

Theses and Dissertations--Molecular and Cellular Biochemistry

Alzheimer’s Disease (AD) is a complex neurodegenerative disease with two hallmark pathologies: extracellular amyloid-b (Ab) and intracellular neurofibrillary tangles (NFTs). Ab is proteolytically processed from amyloid precursor protein (APP) by b-secretase and g-secretase as a monomeric peptide prone to aggregation. Eventually, the aggregate-prone monomers will form dense plaques that are difficult to break down and remove. These plaques begin to deposit into the cortex decades prior to the formation of NFTs and the onset of cognitive decline. NFTs are comprised of hyper-phosphorylated tau. Tau is a protein that serves to promote and stabilize the formation of microtubules. The formation of …

Characterizing The Human Metapneumovirus Matrix Protein And Its Role In Infection, Chase J. Heim

Theses and Dissertations--Molecular and Cellular Biochemistry

Human metapneumovirus (HMPV) causes severe respiratory tract infections in all cohorts, but especially in vulnerable groups such as children, older adults, and the immunocompromised. The matrix (M) protein of HMPV, like the M proteins of other members of the Mononegavirales order, is involved in virus assembly and budding. However, other functions of the HMPV M protein have yet to be elucidated. To investigate these various functions of the M protein, we used a peptide-conjugated phosphorodiamidate morpholino oligomer (PPMO) antisense agent designed to block translation of the M gene to reduce M expression during infection. Treatment with varying concentrations of an …

Duties To Yourself, Julian Sommers

2026 Research Poster Competition

I will be writing a thesis paper with the guidance of Dr. Purdy so I can graduate from the honors program with a bachelor's within philosophy. This paper is still very much in the planning stages, but we have a rough idea of what it will look like. The broad topic is moral duties one could have to themselves and potentially how that relates to duties you might have to others as well. We are interested in this project because I believe our common idea of morality excludes the self from being regarded as a person. I believe morality focuses …

Bridging The Gap In Dentistry: Harnessing Behavioral Health To Improve Oral Health Outcomes For Autistic Youth, Serenity Richardson

2026 Research Poster Competition

Background: Autistic children have unique dental healthcare needs. Oral complications stemming from poor tongue and motor coordination, high sensitivity to toothpaste and flossing, and sensory reactions to fluoride, amalgam, and other dental products are common. Autistic youth are also prone to dental-related emotional (e.g., dental fear and anxiety) and behavioral (e.g., noncompliance, disruptive behavior, avoidance) symptoms. There is also a substantial gap in pediatric and autism-focused training for dental providers, and caregivers report significant challenges in finding dental practitioners who treat autistic children. Taken together, autistic youth and their families face barriers to accessing timely, equitable oral healthcare. Unfortunately, delayed …

The Role Of Ombudsman And Social Work Protecting Rights, Roni Alicia Werner

Selected Full-Text Master Theses Collection 2018-

This thesis examines the role of the Ombudsman as an independent and impartial mechanism for addressing complaints, resolving conflicts, and promoting accountability within organizations.

Rural Women And Intimate Partner Violence: A Geographical Analysis Of Victim Service Providers In The Southern United States, Natalie O'Brien

2026 Research Poster Competition

Intimate partner violence (IPV) is a persistent public safety and public health issue in the United States. Women in rural areas, particularly in the Southern United States, experience disproportionately high levels of frequency and severity. Prior research shows that as communities become more rural, survivors face greater risks of severe violence alongside fewer available support services. This study examines how geographic location shapes help-seeking behaviors and access to victim service providers among adult IPV survivors, with particular attention to differences between rural, suburban, and urban areas in the South. Using nationally representative data from the National Crime Victimization Survey (NCVS) …

Attentional Control, Anxiety, And Depression, Anna Morgan

2026 Research Poster Competition

Anxiety and depression are among the most prevalent and debilitating mental health conditions worldwide. Research suggests that both anxiety and depression are related to deficits in the ability to focus and shift attention, known as attentional control. These effects are present in data using behavioral measures of attentional control (e.g., accuracy in resequencing alphanumeric strings) and self-report measures, though more strongly in the latter. However, studies have found little if any correlation between behavioral and self-report measures of attentional control. One possibility is that anxiety and depression are associated not only with deficits in attentional control, but also more strongly …

Social Isolation Predicts Altered Reward Circuit Connectivity And Future Behaviors In Adolescents, Mason Lucas

2026 Research Poster Competition

Adolescence is a period of transition from childhood to adulthood when people explore risky behaviors. Stressors during adolescence can change structural brain connectivity. Previous research has found weaker structural connectivity between reward circuits and future cognitive impairments among children raised in orphanages. Comparative research in mice suggests that social isolation after bullying can damage these connections and induce alcohol seeking. We tested whether social isolation was related to lower connectivity of targeted structural connections in adolescent humans. We analyzed data from the Adolescent Brain Cognitive Development study and found 130 subjects had experienced extreme social isolation. To evaluate the level …

From Chaos To Clockwork: Investigating The Role Of Circadian Genes In Metabolic Development Of 2nd And 3rd Instar Drosophila Larvae, Elliott Ruegsegger

2026 Research Poster Competition

Connecting deficits in circadian rhythm machinery to the severity of other health conditions is a common task that chronobiology, the study of physiological rhythms, undertakes. Disruptions to circadian rhythms and sleep are linked to increased risk of developing multiple different diseases, including Alzheimer’s Disease and obesity. Circadian rhythms are expressed at the molecular level through rhythmic variations in the concentration of specific proteins. While the central clock genes that produce these proteins, such as period and timeless, are evolutionarily conserved across the animal kingdom, not much is known about the consequences of disruptions in circadian rhythm machinery during early development, …

Assessing Mesenchymal Stem Cell Phenotype After Heparan Sulfate Supplementation, Isani Patel

2026 Research Poster Competition

Multiple sclerosis is an autoimmune disease that damages the protective coating of nerves, often causing lasting neurological symptoms. Current treatments slow disease activity but rarely repair existing damage. In response to this, a novel treatment option has emerged: mesenchymal stem cell (MSC) therapy. MSCs are cells found in different adult tissues like bone marrow, and they have the potential to release repair-supporting signals and moderate inflammation. Nevertheless, results in a clinical setting have been inconsistent due to variations in cell potency. As a potential strategy to enhance MSC therapeutic potential, the addition of heparan sulfate, a naturally occurring signaling molecule, …

Building Mental Health Literacy: The Impact Of Youth Mental Health First Aid On Emerging Youth Professionals, Burgin Rome

2026 Research Poster Competition

Nearly half of individuals in the United States will experience a mental health disorder during their lifetime, with many symptoms first emerging in childhood or adolescence. Adolescence is a critical developmental period characterized by emotional, social, and psychological changes that increase vulnerability to mental health challenges. Although public awareness of mental health has grown, stigma and societal taboos continue to limit open dialogue and delay intervention. As a result, many young people experience a significant gap between the onset of symptoms and receipt of professional support, which can worsen mental health concerns and contribute to long-term consequences that persist into …

Investigating Changes In White Blood Cell Composition In Wild Hosts In Response To Viral Infection, Anna Bolding

2026 Research Poster Competition

Reservoir hosts play a critical role in the persistence and spillover of zoonotic pathogens. Upon infection, reservoir hosts can shed viral loads sufficient for transmission and spillover often without displaying apparent pathogenic effects. Investigating how their immune systems control infection can provide insights into the factors that facilitate spillover events. Understanding the mechanisms that enable these infection characteristics is crucial for informing public health and conservation strategies. Though reservoir hosts’ immune responses are well-documented in controlled laboratory settings, these studies are not representative of natural populations. The bank vole - Puumala hantavirus (PUUV) system is well suited for investigating such …

Temporal Variational Graph Autoencoder For Influenza Evolution, Soumya Chauhan

2026 Research Poster Competition

Frequent mutations in influenza virus surface proteins can increase infectivity while evading human and vaccine immunity, causing seasonal epidemics. The CDC annually evaluates thousands of virus strains to predict mutated sequences likely to be dominant in the next season, which creates a need for methods that better capture how viral mutations evolve over time. In this study, we represent influenza protein sequences as a network-like graph, creating connections if sequences are collected a week apart and only differ by one mutation. This method explicitly considers time information as part of the evolution, while other existing methods analyze mutated sequences without …

Investigating The Potential Role Of Horse Flies (Diptera: Tabanidae) In The Mechanical Transmission Of Anaplasma Marginale And Theileria Orientalis To Cattle In Northwest Arkansas, Catherine Harrison

2026 Research Poster Competition

The cattle industry in Arkansas plays a significant role in the state’s agricultural economy; however, two emerging infectious diseases pose a threat to cattle health, producer livelihood, and animal welfare. The two diseases, anaplasmosis and theileriosis, are caused by organisms that enter the host’s bloodstream and infect red blood cells, leading to destruction of said cells. The shared symptoms of both diseases are fever, weakness, anemia (low red blood cell count), reduced productivity, weight loss, and possibly death. An important difference between symptoms is that, unlike anaplasmosis, theileriosis can cause abortion in cattle. Both diseases are known to spread through …

Cardiovascular Monitoring For Maternal Health Using Wearable Devices, Daniela Alejandra Vasquez

2026 Research Poster Competition

Cardiovascular disease represents the leading cause of pregnancy-related mortality in the United States, accounting for over 30% of maternal deaths, with preeclampsia and hypertensive disorders contributing significantly to this burden. In Arkansas, maternal mortality rates reach 41.9 deaths per 100,000 live births. Current prenatal care relies on intermittent office-based blood pressure measurements conducted during 12-14 clinical visits, may not capture critical cardiovascular changes in a timely manner. Preeclampsia is characterized by new-onset hypertension after 20 weeks of gestation, affects 3-7% of pregnancies, and requires early detection to enable timely intervention. The limited accessibility of ambulatory blood pressure monitoring in rural …

Predictors Of Stigma And Their Relation To Mental Health Help-Seeking Attitude In College Students, Esiquil Lara

2026 Research Poster Competition

Stigma remains a significant barrier for college students seeking mental health services, yet its predictors and impact are still not fully understood. Mental health problems are a large issue in public health, specifically college age adults are one of the most likely groups to develop such issues. This study examines key factors contributing to stigma and its relationship with help-seeking attitudes among undergraduate college students. We hypothesize that students who identify with minority ethnic groups, identify as male, and who are not seeking a career in mental health services will have higher rates of stigma and therefore be less likely …

Individuals living with Crohn’s disease, ulcerative colitis, irritable bowel syndrome (IBS), and related gastrointestinal conditions often face significant physical and emotional challenges following colostomy or ileostomy surgery. While ostomy bags are essential medical devices that support health and survival, they frequently create difficulties related to clothing fit, comfort, discretion, and self-expression. Despite growing conversations around inclusivity and adaptive apparel, the contemporary fashion market offers limited stylish, affordable, and functional clothing options for individuals with ostomies, particularly younger consumers who value both comfort and personal style. This lack of inclusive design can negatively impact confidence, body image, and overall quality of …

Testing The Effects Of Mechanical Stimulation On Mesenchymal Stem Cell Cultures, Ella Collis

2026 Research Poster Competition

Mesenchymal stem cells (MSCs) are a promising treatment option for a variety of diseases due to their ability to migrate to far-off sites, modulate inflammatory immune responses, secrete factors that aid in tissue healing, and their capacity to become several cell types. These cells can be found and isolated from various body tissues including bone marrow and adipose tissue, even so the number of cells obtained from these tissues is minimal compared to the amounts needed for their transplantation in cell therapy treatments. Therefore, their culture in plastic dishes is required to increase the number of cells and obtain the …

When Relevant Isn’T Readable: Evaluating Cognitive Accessibility In Search, Kaija Frierson

2026 Research Poster Competition

According to the World Health Organization, more than one billion people worldwide experience some form of disability. Many of them may affect cognitive processing and reading comprehension rather than vision or mobility, which creates barriers when accessing written information online. Web search is a critical modern literacy skill used for learning, decision-making, and everyday problem solving, yet most search systems are designed with the assumption that all users can process complex written language equally. As a result, people with dyslexia, other cognitive disabilities, low literacy levels, or who are English language learners may struggle to access relevant information even when …
