German Cockroach Allergen Mitigation, Olivia Katz

Theses and Dissertations--Entomology

German cockroaches (Blatella germanica L.) remain one of the most challenging indoor pests to manage, due in large part to their cryptic nature, rapid reproduction, and resistance to insecticides. Because of their close proximity to humans, they also pose several serious health threats, including the production and dissemination of several potent allergens linked to asthma development and exacerbation. Given the risks associated with cockroach allergens, we examined the longevity of two distinct cockroach allergens (Bla g 1 and Bla g 5) in the home environment and the efficacy of cleaners at removing these allergens. Our findings show that Bla …

Seasonal Variation Of The Stream’S Autogenic Sediment Transport Regime, Melissa Beckman

Theses and Dissertations--Civil Engineering

This thesis investigates the autogenic sediment transport regime in a low-gradient stream system in the inner bluegrass region of central Kentucky, USA The seasonality of sediment transport seasonality was not well addressed in prior research for baseflow and low flow periods, to our knowledge, due to the assumption that low flows do not account for considerable fluid transport capacity to move sediment. The hypothesis is that during the autogenic regime the sediment transport in the low-gradient system is being driven by geophysical, biogeochemical, and biological processes. We hypothesize that crayfish are one mechanical driver of sediment transport during these periods. …

Investigation Of Arm Stiffness Modulation During Overground Physical Human-Human Interaction, Henry Tien

Masters Theses

The vision of advancing robots capable of direct physical engagement with humans begins with an understanding of how humans interact with each other. Even rudimentary interactive tasks, such as shaking hands, provides tremendous challenges for modern robotics and current research into the biomechanics of such interactions is limited. Thus, further analysis of physical Human-Human Interaction (pHHI) will bolster efforts to enhance collaborative robot capabilities. To this end, a custom Force Perturbation Handle (FPH) was developed, including the requisite mechanical, electrical, and software systems, to investigate the unique role of arm stiffness modulation in haptic communication between humans. The novel device …

Biosystems and Agricultural Engineering Faculty Publications

The potential benefits of nanopesticide use over standard pesticides include more precise application at reduced application rates, lower premature degradation, and decreased direct impacts to target organisms. However, field scale investigations of the fate and transport of common nanopesticides such as copper (II) hydroxide and imidacloprid combinations, remain limited. A field study evaluating nano-scale copper (II) hydroxide (Cu), standard imidacloprid (I), nanoimidicloprid (NI), and nano-scale copper (II) hydroxide and imidacloprid (CuNI) compared to control (C) plots was conducted using thirty 14.6 m² field plots to determine the impacts of nanopesticide applications on nutrient cycling and quantify the persistence of …

Sam Altman, Openai, And The Importance Of Corporate Governance, Lawrence J. Trautman, Larry D. Foster Ii

Journal of Law, Technology, & the Internet

The sudden firing of CEO Sam Altman by OpenAI’s three independent directors highlights concerns about whether a leading AI company, susceptible to internal conflict and unclear accusations, can be trusted to develop a technology with far-reaching consequences for billions of people.

This paper examines how OpenAI’s board of directors terminated CEO Sam Altman’s employment, a decision that risked hundreds of highly skilled employees walking out the door, disrupted billions of dollars in value, and jeopardized critical knowledge of this important technology. It is hoped that corporate directors—whether at for-profit and non-profit companies—along with venture capitalists, technologists, and government regulators can …

The Effects Of Prenatal Alcohol And Nicotine Exposure On Later-Life Drug-Seeking Behavior And Memory Performance, Zoe Campanella

West Chester University Master’s Theses

Alcohol and nicotine are the two most commonly consumed licit substances among pregnant individuals, and the potential consequences of prenatal exposure to each drug include a variety of neurological and behavioral alterations. These may include an increased likelihood of developing a substance use disorder (SUD) and/or cognitive impairments later in life. However, 30% of pregnant individuals who report consuming alcohol also report consuming nicotine, yet the potential consequences of combined prenatal exposure are not understood. Furthermore, 40% of pregnancies in the U.S. are unplanned, meaning that drug exposure most commonly occurs during the first trimester. However, there is limited research …

Unveiling The Bacterial Communities Of Aphaenogaster: Taxonomic Composition, Developmental And Species Influences, And The Impact Of Climate Change, Lily Kelleher

West Chester University Master’s Theses

Ants are vital keystone species in many ecosystems because they provide ecosystem services such as: seed dispersal, soil bioturbation, and pest control. However, ant bacterial symbioses remain largely unstudied, but these interactions are crucial because microbes play a vital role in the ants’ overall health. Today, global climate change is impacting our biodiversity, and we can use information about how changing temperatures impact the symbiotic bacterial communities associated with ants to predict future impact. Aphaenogaster rudis and A. fulva remain understudied in terms of their bacterial community and are important North American species. For this study, ants from several colonies …

The Physiological Effects Of Anabolic Steroids On The Human Body, Aedan Kerr

Undergraduate Honors Theses

Anabolic-androgenic steroids (AAS) are synthetic derivatives of testosterone used both medically and illicitly for their muscle-building and performance-enhancing properties. While clinically prescribed for conditions like hypogonadism, osteoporosis, and muscle-wasting diseases, AAS are frequently abused by athletes and recreational lifters seeking rapid physical gains. AAS increase muscle protein synthesis via androgen receptor-mediated gene transcription, but they also predispose users to tendon ruptures and various organ functions. AAS abuse is strongly associated with a host of side effects including gynecomastia, male-pattern hair loss, infertility, hepatotoxicity, erythrocytosis, dyslipidemia, insulin resistance, and hypogonadism. Cardiovascular complications such as left ventricular hypertrophy, cardiomyopathy, and myocardial infarctions …

Accurate crop monitoring is essential for optimizing agricultural productivity and ensuring food security. This study presents a comprehensive deep learning framework for image crop type recognition, health status prediction, and disease detection using multiple Convolutional Neural Network (CNN) models. The proposed approach uses open-source datasets consisting of five crop types (apple, corn, grape, potato, tomato), varying health conditions, and common diseases. By deploying specialized CNN architecture focused on each task, the system achieves a high accuracy of 99.25% in classifying crop types, identifying health status, and detecting specific diseases. Compared to a single CNN model, the use of the proposed …

Spectral Divergence Prioritizes Key Classes, Genes, And Pathways Shared Between Substance Use Disorders And Cardiovascular Disease., Everest Castaneda, Elissa J Chesler, Erich Baker

Faculty Research 2025

Introduction: Substance use disorders (SUDs) are heterogeneous diseases with overlapping biological mechanisms and often present with co-occurring disease, such as cardiovascular disease (CVD). Gene networks associated with SUDs also implicate additional biological pathways and may be used to stratify disease subtypes. Node and edge arrangements within gene networks impact comparisons between classes of disease, and connectivity metrics, such as those focused on degrees, betweenness, and centrality, do not yield sufficient discernment of disease network classification. Comparatively, the graph spectrum's use of comprehensive information facilitates hypothesis testing and inter-disease clustering by using a larger range of graph characteristics. By adding a …

Neurological, Metabolic And Inflammatory Phenotypes In A Mouse Model Of Echs1 Deficiency., Meghan M Eller, Aamir Zuberi, Xiaorong Fu, Alina P Montalbano, Felix Nitschke, Shawn C Burgess, Cathleen Lutz, Rachel M Bailey

Faculty Research 2025

ECHS1 deficiency (ECHS1D) is a rare and devastating neurometabolic disease that currently has no defined treatments. This disorder results from missense loss-of-function mutations in the ECHS1 gene that results in severe developmental delays, encephalopathy, hypotonia and early death. ECHS1 enzymatic activity is necessary for the beta-oxidation of fatty acids and the oxidation of branched-chain amino acids within the inner mitochondrial matrix. The pathogenesis of disease remains poorly understood. To expand our knowledge on disease mechanisms, we generated a novel mouse model of ECHS1D that possesses a disease-associated variant knocked-in (KI) the Echs1 allele and a knock-out (KO) of the other …

INTRODUCTION: Marmosets spontaneously develop pathological hallmarks of Alzheimer's disease (AD) including amyloid beta plaques. However, tau expression in the marmoset brain has been understudied.

METHODS: Isoforms of tau were examined by western blot, mass spectrometry, immunofluorescence, and immunohistochemical staining.

RESULTS: 3R and 4R tau isoforms are expressed in marmoset brains at both the transcript and protein levels across ages. Mass spectrometry analysis revealed that tau peptides in marmoset corresponded to the 3R and 4R peptides in human brain, with 3R predominating at birth and an ≈40%:60% 3R:4R ratios in adolescents and adults; tau was distributed widely in neurons, with localization …

Merritt-Putnam Symposium | Developmental And Epileptic Encephalopathies-Current Concepts And Novel Approaches., Rodney C Scott, Jenny Hsieh, Amy Mctague, J Matthew Mahoney, Catherine A Christian-Hinman

Faculty Research 2025

Developmental and epileptic encephalopathies (DEEs) are among the most severe and difficult to treat epilepsies. Two broad strategies for understanding the etiology and impacts of DEEs include genetic and complex adaptive systems approaches. This review, inspired by the 2024 Merritt-Putnam Symposium, describes current perspectives of DEE, identifies limitations of current views, and discusses potential novel ways forward. First, we discuss the rationale for a reevaluation of the role of seizures in the pathogenesis of cognitive and behavioral impairments in DEE. Second, we discuss newly emerging methods employing neural organoids to study brain development and DEE in vitro. Third, we present …

Comprehensive Single-Cell Aging Atlas Of Healthy Mammary Tissues Reveals Shared Epigenomic And Transcriptomic Signatures Of Aging And Cancer., Brittany Lynn Angarola, Siddhartha Sharma, Neerja Katiyar, Hyeon Gu Kang, Djamel Nehar-Belaid, Sunghee Park, Rachel Gott, Giray N Eryilmaz, Mark A Labarge, Karolina Palucka, Jeffrey Chuang, Ron Korstanje, Duygu Ucar, Olga Anczuków

Aging is the greatest risk factor for breast cancer; however, how age-related cellular and molecular events impact cancer initiation is unknown. In this study, we investigated how aging rewires transcriptomic and epigenomic programs of mouse mammary glands at single-cell resolution, yielding a comprehensive resource for aging and cancer biology. Aged epithelial cells exhibit epigenetic and transcriptional changes in metabolic, pro-inflammatory and cancer-associated genes. Aged stromal cells downregulate fibroblast marker genes and upregulate markers of senescence and cancer-associated fibroblasts. Among immune cells, distinct T cell subsets (Gzmk⁺, memory CD4⁺, γδ) and M2-like macrophages expand with age. …

Reproductive Experience Drives Changes In Behaviour And Physiology In Male California Mice, Peromyscus Californicus, Maria E. Colt, Priyanka Agarwal, David Kolb, Erica Glasper, Heidi Fisher

Faculty Research 2025

Paternal experience improves memory and reduces anxiety-like behaviour in males, but it is unclear whether these changes are due to mating, siring offspring or caregiving behaviour. Likewise, paternal males have larger testes, a measure of sperm production, but again, the effects of siring and caregiving experience are difficult to disentangle. We examined behavioural and physiological outcomes in three groups of male mice: (1) virgins, (2) males paired with sterile females (‘nonfathers’) and (3) experienced fathers (experiment 1). Compared to virgins and nonfathers, experienced fathers exhibited increased recognition memory (novel object recognition) and decreased anxiety-like behaviour (elevated plus maze). Virgin males, …

The sudden rise of the SARS-CoV-2 virus and the delay in development of effective therapeutics for mitigation made evident a need for ways to screen compounds that can block infection and prevent further pathogenesis and spread. However, identifying effective drugs that are efficacious against viral infection and replication with minimal toxicity for the patient can be difficult. Monoclonal antibodies were shown to be effective, but as the SARS-CoV-2 mutated, these antibodies became ineffective. Small-molecule antivirals were identified using pseudovirus constructs to recapitulate infection in nonhuman cells, such as Vero E6 cells. However, the impact was limited due to poor translation …

Faculty Research 2025

Antibody–drug conjugates (ADCs) combining monoclonal antibodies with cytotoxic payloads are a rapidly emerging class of immune‐based therapeutics with the potential to improve the treatment of cancer, including children with relapse/refractory acute lymphoblastic leukemia (ALL). CD123, the α subunit of the interleukin‐3 receptor, is overexpressed in ALL and is a potential therapeutic target. Here, we show that pivekimab sunirine (PVEK), a recently developed ADC comprising the CD123‐targeting antibody, G4723A, and the cytotoxic payload, DGN549, was highly effective in vivo against a large panel of pediatric ALL patient‐derived xenograft (PDX) models (n = 39). PVEK administered once weekly for 3 weeks resulted …
