Becoming Mandan: The Collaborative Life History Of Robert O’Brien, Douglas D. Meigs May 2026

Becoming Mandan: The Collaborative Life History Of Robert O’Brien, Douglas D. Meigs

Sociology and Anthropology Theses, Dissertations, and Student Creative Activity

This thesis examines how separation from—and later discovery of—an Indigenous family and culture shapes ethnic identity formation. Grounded in Charles Horton Cooley’s theory of the looking-glass self, it uses collaborative life history methodology to analyze the process of Indigenous identity formation experienced by Robert O’Brien, a Native American orphan who discovered his Mandan, Hidatsa, and Arikara (MHA) heritage as an adult. Drawing on two decades of reflexive research, unstructured interviews, participant observation, and archival documents, the case study shows how O’Brien’s sense of identity developed in response to shifting and often contradictory social mirrors.

Invasive Macrofungi In The United States: A Mushrooming Crisis, Emily Torres May 2026

Invasive Macrofungi In The United States: A Mushrooming Crisis, Emily Torres

Student Theses 2015-Present

Globalization has accelerated the spread of invasive species, making them one of the largest contributors to biodiversity loss worldwide. While invasive macrofungi remain largely absent from scientific discourse on invasive species, they represent a growing ecological concern throughout the United States. Invasive macrofungi disrupt forest ecosystems, alter soil communities, and displace native fungi. Beyond these ecological impacts, their presence and establishment profoundly affect human-nature relationships, most notably mushroom foraging and cultivation practices. This paper adopts a multidisciplinary approach to examine the ecological, economic, and anthropogenic impacts of invasive macrofungi in the United States. Chapter 1 provides a quantitative overview of …

Sonidegib (Lde225) Reduces Inflammatory Signaling And Preserves Taste Buds In A Sepsis Mouse Model, Ashlyn Mcclelland, Murod Khikmatov, Archana Kumari, Gabrielle Audu, Isaiah Nawaz, Kingsley Yin May 2026

Sonidegib (Lde225) Reduces Inflammatory Signaling And Preserves Taste Buds In A Sepsis Mouse Model, Ashlyn Mcclelland, Murod Khikmatov, Archana Kumari, Gabrielle Audu, Isaiah Nawaz, Kingsley Yin

Rowan-Virtua Research Day

Background:

Sepsis triggers a complex and widespread inflammatory response that disrupts multiple organ systems, including the taste organ. Loss of taste is a symptom recognized in sepsis survivors and has the potential to contribute to further complications such as anorexia. Prior work from our lab demonstrated that cecal ligation and puncture (CLP) in mice induces immune cell infiltration and alters taste bud morphology in the fungiform papillae located in the anterior tongue. We hypothesize that similar deleterious effects occur in the circumvallate papillae (CVP) of the posterior tongue and that the usage of the smoothened inhibitor, sonidegib, could reduce these …

Rowan-Virtua Research Day

Title: Atomoxetine enhances specific dimensions of cognitive performance in a rodent strategy shifting assay

Authors: Jessica Ivanov, Christopher P. Knapp, Barry D. Waterhouse, Rachel L. Navarra

Objective: Cognitive flexibility, a domain of executive function, supports adaptive shifts in behavior in response to changing environmental demands and task contingencies. Deficits in this capacity are common to neuropsychiatric disorders such as Attention Deficit Hyperactivity Disorder (ADHD), where improper regulation of the catecholamine transmitters dopamine (DA) and norepinephrine (NE) within the prefrontal cortex (PFC) has been implicated. Atomoxetine (ATX), a selective NE transporter (NET) inhibitor, elevates levels of NE and DA in the …


Phytomining Potential Of Native Rocky Mountain Plants, Halle Cogley May 2026

Phytomining Potential Of Native Rocky Mountain Plants, Halle Cogley

Honors Theses

Standard mining practices of the past have left valuable, critical minerals remaining within mine waste and tailings piles. Phytoremediation, or the use of plants to uptake and store heavy metals, has grown in popularity for these sites. A new technology, phytomining, is being developed that not only offers the benefits of phytoremediation but also allows a new pathway to extract and generate revenue from these untouched critical minerals. Certain plants have been identified as hyperaccumulators with the ability to bioaccumulate a high level of certain minerals in their plant tissue. This study explored different species of native plants within the …

Paqr7 and paqr8 are genes encoding membrane progestin receptor αand β (mPRα and mPRβ, respectively), which are currently classified as members of the progestin and adipoQ receptor (PAQR) family. For mPRα, the first identified mPR gene, there are two paralogs in zebrafish, paqr7a and paqr7b. In order to elucidate the physiological functions of the mPR subtypes, we created gene knockout (KO) fish by editing seven paqr genes in zebrafish and analyzing their phenotypes. The null-mutant strains of paqr7a, paqr7b, and paqr8 presented no significant abnormalities in reproductive functions. Thus, we generated a triple-gene knockout (TKO) strain of …


Developing A Computational Pipeline For Biomarker Discovery In Ischemic Reperfusion Injury, Surabhi Panda, Kaitlyn Insana, Dimitri Pestov May 2026

Developing A Computational Pipeline For Biomarker Discovery In Ischemic Reperfusion Injury, Surabhi Panda, Kaitlyn Insana, Dimitri Pestov

Rowan-Virtua Research Day

Background: Ischemia-reperfusion injury (IRI) contributes significantly to tissue damage in cardiovascular disease. During IRI, stressed and dying cells release ribosomal RNA, which exhibits distinct fragmentation patterns that may serve as potential diagnostic biomarkers. Although these patterns have been observed using low-resolution biochemical techniques, there is currently no standardized computational approach to quantify and visualize RNA fragmentation for clinical interpretation.

Hypothesis: A computational pipeline can be developed to visualize and analyze ribosomal RNA fragmentation patterns, enabling identification of distinct fragmentation hotspots associated with ischemic conditions and potential biomarker discovery.

Methods: RNA fragmentation datasets generated from ribosomal RNA experiments in a Saccharomyces …


Cannabis Use Disorder And Executive Function - A Literature Review, Jonathan Perumpail May 2026

Cannabis Use Disorder And Executive Function - A Literature Review, Jonathan Perumpail

Rowan-Virtua Research Day

Cannabis use disorder (CUD) is recognized as a psychiatric condition characterized by persistent and problematic cannabis consumption that leads to marked functional impairment. Growing evidence suggests that chronic CUD exerts significant effects on executive functions such as inhibitory control, cognitive flexibility, goal-directed behavior, and decision-making. This literature review integrates findings from 25 studies focusing specifically on individuals with objectively diagnosed CUD to explore the effects on cognition in this patient population. Across studies, deficits in executive function are consistently observed, with adolescents and early-onset users demonstrating increased vulnerability. Neuroimaging studies reveal structural and functional alterations in the prefrontal cortex and …

Rowan-Virtua Research Day

Background: Post-Traumatic Stress Disorder (PTSD) is a prevalent and debilitating condition, and is most often associated with sleep disturbances such as nightmares, flashbacks, and heightened arousal. Prazosin, an alpha-1 adrenergic antagonist, has been widely used for PTSD symptoms, however findings across studies are variable and limited, and the scope of existing evidence is not well established.

Objective: This scoping review aims to systematically map the literature on the use of prazosin in individuals with PTSD across diverse populations, settings, and study designs.

Methods: The scoping review will be conducted in accordance with JBI methodology and reported following PRISMA-ScR guidelines. A …


Invisible Shipwrecks And Neurological Endangerment: The Trade-Off In Seeking Asylum - Reframing The Neurobiological Cost Of Forced Migration, Eisha Giran May 2026

Invisible Shipwrecks And Neurological Endangerment: The Trade-Off In Seeking Asylum - Reframing The Neurobiological Cost Of Forced Migration, Eisha Giran

CISLA Senior Integrative Projects

Forced migration along the Spain–Morocco route represents one of the most visible humanitarian crises of the twenty-first century, yet its neurological dimensions remain insufficiently examined. This paper investigates how prolonged displacement and trauma reshape neural systems involved in stress regulation, memory, and emotional processing. It introduces the concept of neurological endangerment, defined as a condition of prolonged and inescapable threat exposure during forced migration in which stress-response systems remain chronically activated, opportunities for recovery are structurally constrained, and cumulative neurobiological risk persists beyond the period of immediate danger.

To address the gap between biological measurement and lived experience, this paper …

Case Report: Acute Encephalopathy Revealing Severe Babesiosis With Lyme Co-Infection, Czarina Gebrelle K. Soriano, James Espinosa, Alan Lucer May 2026

Case Report: Acute Encephalopathy Revealing Severe Babesiosis With Lyme Co-Infection, Czarina Gebrelle K. Soriano, James Espinosa, Alan Lucer

Rowan-Virtua Research Day

Acute confusion in older adults is a common emergency department presentation with a broad differential diagnosis. Tick-borne illnesses can cause significant systemic disease and may present with nonspecific neurologic or constitutional symptoms, making early recognition challenging. Babesiosis is a tick-borne parasitic infection transmitted by Ixodes ticks and may occur concurrently with other infections such as Lyme disease, further complicating diagnosis. We present a case of a 67-year-old male who presented with acute confusion and was found to have concurrent babesiosis and Lyme disease. This case highlights the importance of maintaining a high index of suspicion for tick-borne co-infections in patients …


Anticipating Animal Ethics Concerns In Islet Xenotransplantation, Sheetal Mohanty, Daniel J. Hurst, Amy Glasofer May 2026

Anticipating Animal Ethics Concerns In Islet Xenotransplantation, Sheetal Mohanty, Daniel J. Hurst, Amy Glasofer

Rowan-Virtua Research Day

Type 1 diabetes mellitus (T1D) necessitates life-sustaining insulin therapy or, in select cases, islet allotransplantation, which is limited by donor scarcity. Islet xenotransplantation (XTx; genetically modified pig-to-human transplant) is one potential alternative. Patient perceptions about islet XTx are largely unexplored. This study examined patient support for XTx when T1D patients learned that 25-50 pigs may be needed to treat one adult. Patient viewpoints toward islet XTx suggest animal ethics concerns may extend to the magnitude of animals required to treat a single patient. As clinical trials advance, addressing these values and risk tolerances is essential for developing informed consent frameworks …

Identification Of Genes Regulating The Gli Protein Tra-1 In ​Caenorhabditis Briggsae Through A Genetic Suppressor Screen​, Alexander Glenn Cabrera, Sanese Brown-White, Ronald Ellis May 2026

Identification Of Genes Regulating The Gli Protein Tra-1 In ​Caenorhabditis Briggsae Through A Genetic Suppressor Screen​, Alexander Glenn Cabrera, Sanese Brown-White, Ronald Ellis

Rowan-Virtua Research Day

BACKGROUND:
Gli proteins are conserved transcription factors that regulate cell fate, proliferation, and patterning. In Caenorhabditis briggsae, the Gli protein TRA-1 functions as the terminal regulator of the sex-determination pathway to control sexual development. These nematodes lack Hedgehog signaling, so TRA-1 is regulated by other factors. The missense mutation tra-1(v48) disrupts TRA-1 activator function, resulting in complete feminization of XX animals, which would otherwise be hermaphrodites.

HYPOTHESIS:
Suppressor screens using tra-1(v48) mutants will identify novel cofactors required for TRA-1–mediated Gli activation and spermatogenesis.

METHODS:
Ethyl methanesulfonate (EMS) mutagenesis was performed on tra-1(v48) strains to induce random mutations. Dominant suppressors were …

Adolescent Opioid Use And Prefrontal Cortex Development - A Systematic Review, Jonathan Perumpail, Liam Kerrick, Shreya Kadi May 2026

Adolescent Opioid Use And Prefrontal Cortex Development - A Systematic Review, Jonathan Perumpail, Liam Kerrick, Shreya Kadi

Rowan-Virtua Research Day

Adolescence represents a critical period of neurodevelopment characterized by ongoing maturation of the prefrontal cortex (PFC), a brain region essential for executive function, impulse control, and behavioral regulation. Exposure to opioids during this vulnerable window may disrupt neural development and lead to long-term consequences. This review synthesizes current preclinical and human evidence examining the effects of adolescent opioid exposure on PFC development. Across rodent models, opioid exposure is associated with impaired synaptogenesis, altered dopaminergic signaling, and dysregulation of the prefrontal-mesolimbic circuits involved in decision making. Human studies showed reduced functional connectivity and white matter changes in those with opioid use …

Mathematics and Statistics Faculty Research & Creative Works

Down syndrome (DS) is caused by the triplication of human chromosome 21 (Hsa21), resulting in skeletal insufficiency (low bone mineral density) and altered bone development. DS mouse models recapitulate these deficits, including sexual dimorphism in long bone alterations. Historically, Ts65Dn mice provided much of the insight behind DS-related skeletal deficits with ∼100 trisomic orthologous genes, but there are concerns about the genetic fidelity in this model due to the included triplication of genes not homologous to Hsa21. A new DS model, Ts66Yah, subtracted the non-Hsa21 homologous trisomic genes from Ts65Dn but has not been evaluated for long bone deficits. Comparing …


Parlache: The Spread Of Narco(Tics) Slang And Its Impact On The Colombian Lexicon And Culture, Savannah E. Taylor May 2026

Parlache: The Spread Of Narco(Tics) Slang And Its Impact On The Colombian Lexicon And Culture, Savannah E. Taylor

The Corinthian

The current paper details the emergent use of Parlache, a unique Colombian urban slang, which has become popular among the low-income barrios, or slums, of Medellin and other cities in Colombia. Parlache was born largely out of the necessity for the Medellin Cartel to remain undetected by law enforcement, in conjunction with a major socioeconomic crisis that tore through urban sprawl in the 1980s. Much of its vocabulary is comprised of code words born in the cartel, however, has also been incorporated into popular urban culture in written and spoken form, such as songs, TV shows, day to …


Acquisition Behavior Response: Investigating The Ability Of Leptoglossus Phyllopus To Choose Between A “Good” Versus “Sub-Optimal” Strain Of Caballeronia, Irene L. Pham May 2026

Acquisition Behavior Response: Investigating The Ability Of Leptoglossus Phyllopus To Choose Between A “Good” Versus “Sub-Optimal” Strain Of Caballeronia, Irene L. Pham

2026 Spring Honors Capstones Projects

Leptoglossus phyllopus is a polyphagous pest that primarily feasts on citrus, tomatoes, and legumes. They must form a mutualistic symbiosis with Caballeronia every generation by ingesting the bacterium from their environment. However, not all species of Caballeronia confer the same fitness on the L. phyllopus host, raising the question of whether L. phyllopus possesses a partner choice mechanism that would allow it to distinguish between a good (GAOX1) and a suboptimal (Lep1P3) symbiosis partner. This was examined by conducting a choice experiment in which the two symbionts (GAOX1 vs. Lep1P3) were placed in a plastic box, and the bug’s roaming …
