Effects Of Novel Dopamine D4 Receptor-Targeted Compounds On Locomotor Activity And Anxiety-Like Behavior In Male And Female Sprague Dawley Rats, Samantha Alyse Walkow, Noah A. Ivak, Daniel Chandler, John Tkaczynski, Thomas M. Keck, Comfort A. Boateng, Eleni Papadopoulos, Barry D. Waterhouse, Rachel L. Navarra

Rowan-Virtua Research Day

The consequences of modulating subtypes of G protein coupled dopamine receptors are broadly studied for their role in decision making behavior, specifically in situations involving uncertain risk and reward. The actions of dopamine D4 receptors (D4Rs) on these complex processes are the least understood, particularly due to a lack of available compounds with suitable selectivity for D4Rs. Further, current research often fails to evaluate how modulating specific dopamine receptor subtypes may affect locomotor activity and anxiety-like behavior as confounding factors prior to assessing their function in behavioral assays of higher order decision making. The goal of the current study was …

Ks151 Synergizes With Venetoclax And Abt-737 In Aml: Efficacy In Both Flt3-Wildtype And Flt3-Mutant Models, Sahil Jethi, Arnold Rojas, Omar S. Al-Odat, Krishne Gowda, Subash C. Jonnalagadda, Manoj Pandey

Rowan-Virtua Research Day

Acute myeloid leukemia (AML) is the most common leukemia in adult patients, with a 5-year survival rate of less than 30 percent. Therefore, more effective therapeutic strategies are required to prolong the survival of AML patients. Importantly, anti-apoptotic proteins, especially B-cell lymphoma 2 (Bcl-2), overexpression in AML is associated with uncontrolled growth as well as chemoresistance. Unsurprisingly, Bruton’s tyrosine kinase (BTK) overexpresses in AML and associated with poor prognosis and chemoresistance. The FDA-approved BTK inhibitor, ibrutinib, has been successful in treating other hematologic malignancies, but a proportion of patients relapse mainly because of acquired mutations at Cys481Ser (C481S) in the …

Characterizing Environmental Background Microflora And Assessing Their Influence On Listeria Persistence In Dairy Processing Environment, Vaishali Poswal, Sanjeev Anand, Brian Kraus

Dairy Science and Food Science Faculty Publications: 2022 to Present

Listeria monocytogenes (Lm) may persist in food processing environments (FPEs) alongside diverse background microflora. While microbial communities in FPEs can in- fluence Lm survival, their role in supporting or suppressing its growth remains unclear. This study aimed to characterize the microflora in floor swabs and air samples collected from a dairy processing facility across three seasons and assess their potential impact on the growth of a Lm test strain previously isolated from a dairy processing environment. A total of 167 environmental isolates, representing 30 bacterial genera, were identified. Pseudomonas was consistently prevalent across all sample types. Seasonal shifts in bacterial …

Identification And Environmental Impact Of 35 Different Cut Flower Retail Packages In The U.S.A., Mary Kathryn Gillespie

All Theses

Cut flowers represent 35-billion dollars of global spending with 10-million dollars per day in the U.S.A; each transaction involving packaging. Across the country, cut flower packaging is inconsistently sized, laminated, colored, and unlikely to be recycled. 35 unique cut flower packages were collected across 16 different marketplaces, representing 88% of top grocery retailers. Measuring the materiality of the predominately unlabeled and inconsistent packaging collected required calorimetry equipment, such as Fourier-transform Infrared Spectroscopy, Differential Scanning Calorimeter, and precision gauges.

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 …

Advancement Of Wrongful Conviction Prevention Strategies In Forensic Science, Isabella Pinto

Honors Projects

The National Registry of Exonerations (NRE) has identified 1,051 of its logged cases to involve forensic evidence in some way, nearly one-third of the total 3,600 exonerations in its database. Analysis of the NRE and Innocence Project databases revealed the most common factors in forensic-related wrongful convictions: expert testimony, flawed methodologies (most of which are no longer in use), and statistical misinterpretations of results. The majority of scholars agree that oversight in forensic casework must be improved in order to meaningfully resolve issues. Creation of commissions in each state would address all of the identified errors, though not a catch-all …

Quantifying Freshwater Salinization Impacts On Nitrate Removal Via Denitrification In Urban Streams, Brynnen Beck

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

As the urban world expands, the construction of impervious surfaces increases erosion and runoff into nearby streams. Urbanization also adds waste from human activity into the environment. One of these wastes is runoff from road salt application in winter months, which can increase stream salinization and interfere with other important ecological processes, such as denitrification. Therefore, the objective of this study was to compare nitrate removal via denitrification between two urban streams to understand the role of road salts in freshwater salinization. We compared conductivity measurements between the streams to see how background conductivity (a proxy for salinity) influences resilience …

Relationship Between Nutritional Knowledge And Eating Disorder Risk Levels, Valeria Fernandez

Human Nutrition and Hospitality Management Undergraduate Honors Theses

The prevalence of disordered eating is a critical public health concern that often progresses towards the development of a diagnosable eating disorder (ED). This, in turn, has detrimental physical and psychological consequences for individuals. Organizations such as the American Society of Parenteral and Enteral Nutrition (ASPEN) and the Academy of Nutrition and Dietetics (AND) have recognized nutrition education as a crucial component of prevention and recovery. Determining the extent to which nutrition knowledge is related to risk factors for EDs is worth investigating due to its implications for healthcare approaches – especially among adolescent and young adult populations. The goal …

The Movement Ecology, Ranging Patterns, And Territoriality Of Azara’S Owl Monkeys (Aotus Azarae) In The Argentinean Chaco Forest, Jeremy D. Pustilnik

Azara’s owl monkeys (Aotus azarae) are small, pair-living, socially monogamous primates that inhabit the Chaco Forest of South America. Their activity and life history patterns have been particularly well studied, however, their movement ecology and ranging patterns within their home ranges remains largely unknown. Herein I descriptively analyze these patterns with respect to time, space, ambient environment, and physical environment using spatial information on five owl monkey groups that were followed over the course of a year between 1998 and 1999 at a multi-decade-operating field site near Formosa, Argentina. Analysis of distance and speed moved during different diel …

Empowering Diversity: A Comprehensvie Approach To Minority Risk Management Education, Jahqethea Johnson

Applied Science Program: Theses

Federal programs are pivotal to the foundation of the United States agricultural sector. Program payments impact the economic well-being of agricultural producers, yet accessibility, outreach and education disparities remain prevalent among socially disadvantaged producer and agriculturists. From 2020-2024, an average of $21.7 billion dollars in federal agricultural payments have been paid to producers. Although federal funding historically supports commodity crops, livestock producers also depend on a distinct set of federal risk management programs, which are often less visible but pertinent for operational sustainability. There is a growing focus on the need for addressing disparities faced by socially disadvantaged producers and …

The Great Animal Rights Debate: From The Past Into The Present, Dayna Wiley

Celebrating Scholarship and Creativity Day (2018-)

Animal rights are not a novel concept, and everyone has their own beliefs about where animals should fit into the hierarchy of life. Not so different from today, a debate occurred in the ancient world between the Stoics, represented by Aristotle, and Plutarch, with each questioning whether animals are capable of rational thought or feelings, and therefore whether they are deserving of justice. There is much to learn from the ancient world about the modern debate on animal rights, and there is a striking comparison between this ancient debate and the modern questions of animal rights. But how similar are …

Investigation Into The Microbiome Of Blow Fly Eggs Using Microseqtm Id, Samantha S. Davis, Drusilla Sheridan, Jennifer Rosati

Undergraduate Research

There is little published research characterizing the microbiome associated with blow fly eggs and how they may affect the colonization behaviors of certain blow fly species. Once deposited, blow fly eggs are rapidly introduced to a diverse range of microorganisms, which can vary depending on the species of blow fly, the environment, and the decomposition stage of the substrate (Junqueira et al., 2017). Since blow flies are among the first insects to colonize decomposing remains, the microbial communities present on their eggs could serve as key indicators of the decomposition stage at the time of egg-laying, thus providing a potential …

Decoding Oncology-Focused Biotechnology Firms: Lifecycle Analysis And Predictive Insights For Valuation From A Junior Associate's Perspective, Kesav P. Chandrasekhar

Finance Undergraduate Honors Theses

Oncology-focused biotechnology firms present unique valuation challenges due to high R&D costs, long development timelines, and uncertain clinical outcomes. This thesis addresses such challenges by integrating the clinical development lifecycle with financial valuation models to provide predictive insights into company value. A structured framework is developed that primarily focuses on stage-specific probabilities of success (PoS) for drug candidates and their impact on firm valuation, embedded in techniques such sum-of-the-parts (SOTP) analysis. By quantitatively linking clinical trial phases and likelihoods of approval to cash flow projections, the model enables a more realistic, risk-adjusted estimation of a biotech firm's worth. Through lifecycle …

Dental Microwear Of Miocene Primates From The Carpathian Basin, Rudabánya, Hungary, Anna K. Wilcox

Biological Sciences Undergraduate Honors Theses

This study reconstructs and compares the dietary habits of the late Miocene primates Anapithecus hernyaki and Rudapithecus hungaricus by analyzing dental microwear patterns on fossilized teeth recovered from Rudabánya, Hungary. Previous research suggested that these sympatric species were both primarily frugivores but were unable to separate them by diet. However, earlier studies were limited by smaller sample sizes and less advanced methodologies. This study used an expanded sample and modern microwear texture analysis techniques to compare molar and incisor microwear patterns between the two species. Results revealed that Rudapithecus molars exhibited higher complexity compared to Anapithecus molar complexity, suggesting a …

Biological Sciences Undergraduate Honors Theses

Clostridioides difficile is a major cause of severe gastrointestinal infections and diseases, particularly in healthcare settings. Because of its ability to produce infectious endospores by sporulation, the protein SpoIIE, which is known to play a role in the regulation of this process, is being explored as a potential therapeutic target. In order to gain better insight into the structure and function of this protein, a concentrated and purified sample of the protein must be obtained. The goal of this study was to determine the conditions that would yield the highest amount of SpoIIE. The density of the cultures of bacteria …

Identifying Novel Molecular Targets To Induce Ferroptosis In Drug-Tolerant Cancer Cells Through Computational Modeling, Haris J. Rana

Biological Sciences Undergraduate Honors Theses

Ferroptosis is an iron-dependent, reactive oxygen species (ROS)-driven form of regulated cell death in which the cell membrane is degraded by lipid peroxidation. It is regulated by multiple enzymes, such as glutathione peroxidase 4 (GPX4), which prevents membrane degradation by reducing lipid peroxides and protecting cells from oxidative damage. When inhibitors like RSL3 target GPX4, lipid peroxides build up, and toxic ROS compromises membrane integrity. Traditional anticancer treatments, such as most chemotherapies, aim to eliminate tumor cells by damaging DNA and triggering apoptosis. However, resistance to apoptosis is a “hallmark of cancer,” often resulting in treatment failure. As a distinct …

Habitat loss, fragmentation, and land use changes in river networks are common globally. The resulting fragmentation of landscapes and riverscapes threatens biodiversity and can affect dispersal and subsequently, gene flow and genetic health of species. Headwater streams are an integral part of river networks and contribute to biodiversity by providing habitat for temporary and permanent residents, yet they are easily altered and fragmented. The sandhills chub (Semotilus lumbee) is an endemic headwater leuciscid that lives in highly fragmented streams of the sandhills ecoregion in North and South Carolina, USA. New knowledge on the population genetics of the sandhills chub is …

The Impact Of Irrigation On Agricultural Land Values In The United States Southeast And An Analysis Of Farmland Prices In South Carolina, Christopher L. Thomas

All Theses

Land is a key component of the agriculture industry in the United States. According to the United States Department of Agriculture, farm real estate (land and buildings) accounted for 82.8% of total US farm sector assets in 2022, consequently making land the largest source of wealth in a farmer’s investment portfolio and the primary source of collateral used for farm operating loans. The Southeastern region of the United States has seen rapid farmland appreciation and intense population growth in recent years. This research investigates the rising farmland prices across the Southeast from both a regional and state-level perspective. Chapter Two …

Soil-Based Emissions And Context-Specific Climate Change Planning To Support The United Nations (Un) Sustainable Development Goal (Sdg) On Climate Action: A Case Study Of Georgia (Usa), Davis G. Nelson

All Theses

Soil-based emissions from land conversions are often overlooked in climate planning. The objectives of this study were to use quantitative data on soil-based greenhouse gas (GHG) emissions for the state of Georgia (GA) (USA) to examine context-specific (temporal, biophysical, economic, and social) climate planning and legal options to deal with these emissions. Currently, 30% of the land in GA has experienced anthropogenic land degradation (LD) primarily due to agriculture (64%). All seven soil orders were subject to various degrees of anthropogenic LD. Increases in overall LD between 2001 and 2021 indicate a lack of land degradation neutrality (LDN) in GA. …

Don’T Be A Big Baby: Phenotypic Novelty In The Facultative Paedomorph Ambystoma Talpoideum., Andrew S. Kanes

All Theses

This thesis explores the relationship between heterokairy and the skin microbiota of amphibians, specifically focusing on the facultatively paedomorphic salamander, Ambystoma talpoideum. Heterokairy refers to variations in developmental timing that generate phenotypic novelty within life stages. The first chapter investigates how reordering metamorphosis relative to sexual maturation affects the skin microbiota in this species. By sampling different life stages—larval, paedomorphic, and metamorphic—results show the emergence of novel microbial combinations, resulting from both microbial gain and loss in the heterokairic paedomorphic stage. These findings suggest that changes in microbial communities may lead to phenotypic novelty and have broader eco-evolutionary implications. …

Positive Impact Of Mangroves On Periwinkle Snail (Littoraria Angulifera) Population Size, Anna Jones, Eva Kolbow, Lucy Petschel, Morgan Stone

Celebrating Scholarship and Creativity Day (2018-)

Mangroves play a crucial role as shoreline aquatic nurseries and provide infrastructure along bodies of water to protect inland areas from extreme weather and storm surges. Mangroves also provide a secure habitat for animals, and trap and filter pollutants. Their stilt roots provide shelter for fish species and are critical to the survival of many small species that use this ecosystem. We investigated mangrove periwinkle snail populations on the red mangrove species (Rhizophora mangle). Data was collected along Pigeon Creek, San Salvador Island, Bahamas in March 2025. We hypothesized that there is a relationship between mangrove density and snail population …

The Effect Of Anthropogenic Sound On Foraging Behavior In Bluegill Sunfish (Lepomis Macrochirus), Dayna Wiley

Celebrating Scholarship and Creativity Day (2018-)

Anthropogenic noise can have adverse effects on fish populations. High-amplitude noise can cause hearing damage and interfere with essential behaviors, including feeding, migration, and reproduction. Studies suggest that fish regularly exposed to boat noise in lakes exhibit different behavioral responses compared to populations in quieter environments. Bluegill sunfish (Lepomis macrochirus) were collected via angling from a “Quiet Lake” (Lake Sagatagan, Collegeville, MN) with no motor use, and a “Loud Lake” (Upper Spunk Lake, Avon, MN) with frequent motor use. Bluegill foraging behavior was examined in response to daily playback of motorboat traffic. Bluegill (n = 5 individuals per trial; n …
