Evops: Evolutionary Patch Selection In The Embedding Space Of Whole Slide Images, Saya Hashemian
Evops: Evolutionary Patch Selection In The Embedding Space Of Whole Slide Images, Saya Hashemian
Theses and Dissertations (Comprehensive)
Computational pathology increasingly relies on the analysis of Whole-Slide Images (WSIs), which capture tissue specimens at gigapixel resolution. Because a single slide is far too large to process directly, the
prevailing paradigm decomposes each WSI into thousands of small patches and encodes them as high- dimensional feature embeddings using deep learning backbones. While effective, this paradigm carries a
substantial cost: the resulting collections of patch embeddings are computationally expensive to store and process, and they are frequently dominated by redundant, homogeneous, or otherwise uninformative tissue regions that dilute the diagnostic signal. Existing patch selection methods largely depend on heuristic or …

Independent Animal Chiropractic Practice: An Evidence-Based Argument For Autonomy Beyond Veterinary Supervision, Montana Adams
Independent Animal Chiropractic Practice: An Evidence-Based Argument For Autonomy Beyond Veterinary Supervision, Montana Adams
Undergraduate Honors Theses
Animal chiropractic is a growing form of conservative care used to improve mobility, reduce pain, and support neuromusculoskeletal function in animals. Despite evidence suggesting it is both effective and low risk, access remains limited due to inconsistent state regulations. Many jurisdictions require chiropractors to obtain veterinary supervision, referral, or licensure, even when they have completed specialized training and certification in animal chiropractic. This paper evaluates the effectiveness and safety of animal chiropractic while analyzing the impact of current regulatory policies. Research indicates that chiropractic care can improve mobility and reduce spinal conditions in animals when performed by trained professionals. However, …
Mitochondria As Primary Cause Of Neurodegeneration: Evaluating Causality Across Amyotrophic Lateral Sclerosis (Als), Alzheimer's, And Parkinson’S Diseases, Makenzie G. Johnson
Mitochondria As Primary Cause Of Neurodegeneration: Evaluating Causality Across Amyotrophic Lateral Sclerosis (Als), Alzheimer's, And Parkinson’S Diseases, Makenzie G. Johnson
Undergraduate Honors Theses
Neurodegenerative diseases like Alzheimer's Disease (AD), Parkinson’s Disease (PD) and Amyotrophic Lateral Sclerosis (ALS) have historically been explained through alternate hypotheses despite shared clinical hallmarks that lead to neuron loss. However, these varying explanations could not account for how disease onset begins among other individual issues. This thesis aims to show that mitochondrial dysfunction is a primary driver of neurodegeneration as well as a unifying mechanism shared between the three diseases. Evidence presented in this thesis will show that many issues can arise in mitochondria including issues with energy production, mitochondrial DNA (mtDNA), apoptosis activation, and calcium regulation. These issues …

Acute Responses To Low-Intensity Aerobic Exercise With Continuous And Intermittent Blood Flow Restriction, James Brown, Jakob D. Lauver, Timothy R. Rotarius, Justin P. Guilkey
Kinesiology
Introduction: This study examined muscular and cardiovascular responses to light-intensity aerobic exercise with different blood flow restriction (BFR) protocols. Methods: Ten males performed four protocols on the cycle ergometer: low-intensity exercise with no BFR (LIE), LIE with continuous BFR (CONT-BFR), LIE with intermittent BFR (INT-BFR), and high-intensity exercise (HIE). Each protocol consisted of five 2-min work intervals (INT) at 35% of peak work rate for LIE, CONT-BFR, and INT-BFR and 70% of peak work rate for HIE. During CONT-BFR, cuffs were inflated to 60% of arterial occlusion pressure (AOP) at the start of INT 1 and remained inflated until the …

Fisheries Research Report No. 359: Metropolitan Monitoring Program 2025, Alissa Tate, Claire B. Smallwood, Karina L. Ryan, Troy Matthews
Fisheries Research Reports
Ongoing monitoring of recreational fisheries in the Perth Metropolitan zone is essential to ensure the sustainable use of fisheries resources. Surveys of shore- and boatbased recreational fishers within the Metropolitan zone of the West Coast bioregion provide information on human dimensions and catch-per-fisher as well as mean length and weight of key recreationally caught species. For shore-based fishers, estimates of fishing effort, catch and harvest are also presented for key nearshore species. This information is used to support ongoing assessments for key nearshore species and the development and evaluation of harvest strategies and other management actions, such as for Australian …

Juvenile idiopathic arthritis (JIA) is a chronic autoimmune disease that negatively affects ~100,000 children under the age of 16 in the United States. About ~30% of these patients fail first-line drug therapy with low-dose methotrexate (MTX) due to poor tolerability or lack of efficacy. The SLCO1B1*14 allele is associated with increased MTX clearance and has been linked to reduced overall drug exposure and nonresponse to MTX in JIA patients. Herein, we describe transgenic hSLCO1B1*14 and hSLCO1B1*1 DBA1/J mSlco1b2 knock-out mice, which we used to assess arthritic response to MTX using the collagen-induced arthritis model. Mass spectrometry-based proteomics analysis revealed that …

Plants carrying a mutation in S-nitrosoglutathione reductase 1 (GSNOR1) accumulate high nitric oxide (NO) and exhibit impaired immunity characterized by reduced pathogen-responsive salicylic acid (SA) accumulation and failure to activate normal SA signaling. We show that this reduced SA responsiveness in gsnor1 plants arises from impaired vascular-associated movement of SA, thereby compromising systemic acquired resistance (SAR). Elevated NO perturbs cellular pH homeostasis, acidifying the apoplast and alkalinizing the cytosol, which likely interferes with phloem-associated SA movement and renders gsnor1 plants unresponsive to foliar SA. In contrast, SA supplied via root drench restores SA signaling and SAR in gsnor1, …
Evaluation And Enhancement Of Suspected Opioid Overdose Definitions In Emergency Medical Services Data Using Machine Learning With Natural Language Processing, Peter Rock, Svetla Slavova, Sharon L. Walsh, Julia Martin, Daniel R. Harris
Evaluation And Enhancement Of Suspected Opioid Overdose Definitions In Emergency Medical Services Data Using Machine Learning With Natural Language Processing, Peter Rock, Svetla Slavova, Sharon L. Walsh, Julia Martin, Daniel R. Harris
Institute for Biomedical Informatics Faculty Publications
Background: Fatal and non-fatal drug overdoses have evolved into a critical public health crisis, with over a 50% increase in the rate of fatal drug overdose since 2019. Emergency Medical Services (EMS) data has advantages over traditional emergency department data, including timeliness and captured non-transport encounters. However, there is no consensus EMS definition for suspected opioid overdose (SOO), and currently implemented knowledge-based (KB) definition may miss ambiguous cases. Machine learning with natural language processing (ML-NLP) has the potential to enhance SOO identification.
Methods: Secondary data originated from an oversampled dataset of 2,327 weighted encounters from Kentucky State EMS data (2018–2022). …

Temporal Evolution Of Brain Inflammation In The Bilateral Common Carotid Artery Stenosis Model Of Chronic Cerebral Hypoperfusion, Makayla F. Cox, Jill M. Roberts, Ryan K. Shahidehpour, David L. Dornbos Iii, Adam D. Bachstetter
Neuroscience Faculty Publications
Chronic cerebral hypoperfusion is a major contributor to vascular cognitive impairment and dementia, primarily through its disruption of white matter integrity and promotion of neuroinflammatory cascades. The bilateral common carotid artery stenosis (BCAS) model has emerged as the predominant experimental approach for studying the effects of chronic cerebral hypoperfusion, particularly in aging-relevant contexts. This review synthesizes current knowledge of inflammatory responses in the BCAS model, with an emphasis on their temporal progression and functional consequences. We begin by outlining the clinical burden of hypoperfusion, the rationale for BCAS, and the hemodynamic phases it produces. We then examine early neurovascular unit …

Artificial light at night (light pollution) is widespread but understudied in the context of Alzheimer’s disease (AD). Sleep and circadian disruption have been linked to amyloid-β (Aβ) accumulation and neuroinflammation, but whether dim light at night (dLAN) modifies these processes remains unclear. We tested whether chronic dLAN exposure (8 lux during the dark phase, 8 weeks) alters circadian rhythms, amyloid pathology, and neuroinflammation in 12–13 month-old humanized APP knock-in (KI) mice. hAPPSAA KI mice, which develop plaques, were compared with hAPPWT KI controls carrying only a humanized APP sequence. dLAN reduced circadian rhythm amplitude and stability while increasing …

Toxicology and Cancer Biology Faculty Publications
Brain-Derived Extracellular vesicles (BDEVs) are emerging mediators of intra- and interorgan communication in neurodegenerative diseases (NDs) such as Alzheimer’s Disease (AD) and Parkinson’s Disease (PD). A growing body of evidence suggests that BDEVs play an important role in modulating intercellular communication within the central nervous system in the pathogenesis of many NDs. By transporting non-coding RNAs (e.g., miRNAs) and important pathological proteins, BDEVs also influence peripheral organs and contribute to the progression of disease in the central nervous system (CNS). This review extends the understanding of NDs beyond solely brain dysfunction and gives a novel framework for the progression of …

Organophosphate flame retardants (OPFRs) are used in many consumer products, and their presence in our environment raises concerns about potential health dangers. In humans, exposure to OPFRs, such as tris(1,3-dichloro-2-propyl) phosphate (TDCPP) is associated with metabolic disorders such as obesity, hyperglycemia, and insulin resistance. Our current study seeks to determine how TDCPP exposure affects body composition, glucose homeostasis, and energy balance in a rodent model. C57Bl/6 J mice were divided into two weight-matched groups and fed purified low phytoestrogen diets containing either 0.1 % DMSO (control) or TDCPP 415 mg/kg resulting in an approximate exposure of 50 mg/kg/day. Both male …
Contribution Of Metabolism-Independent Glucose Sensing To Metabolic Homeostasis, Nadia Rashid, Kavaljit H. Chhabra
Contribution Of Metabolism-Independent Glucose Sensing To Metabolic Homeostasis, Nadia Rashid, Kavaljit H. Chhabra
Pharmacology and Nutritional Sciences Faculty Publications
Glucose sensing and signaling are central to cellular metabolic machinery for the regulation of metabolic homeostasis. Glucose sensing has been almost always assumed to be coupled with glucose metabolism; however, recent findings have unraveled metabolism-independent sensing mechanisms. Here, we discuss whether glucose transporters (GLUTs) and sodium-glucose co-transporters (SGLTs) may also function as glucose sensors independent of their roles in transporting glucose. Moreover, we review the emerging roles of G protein-coupled receptors (GPCRs) in sensing glucose and, consequently, initiating its signaling pathways in a cell-specific manner. Altogether, this review offers insights into the newly identified glucose sensing mechanisms and highlights the …

Anatomical Atlas Of Kinase Responsiveness To Weight Gain: Adipose Depot Reprogramming In Diet-Induced Adiposity, Wang-Hsin Lee, Zachary A. Kipp, Sally N. Pauss, Genesee J. Martinez, Mei Xu, Terry D. Hinds, Jr.
Pharmacology and Nutritional Sciences Faculty Publications
Background/Objectives: Adipose tissue depots located at different anatomical sites exert differential functions in response to adiposity and glucose intolerance. These fat depots exhibit distinct metabolic signaling patterns that may influence pathological fat accumulation, thereby affecting the efficacy of anti-obesity interventions. Nonetheless, the mechanisms underpinning depot-specific signaling and pathway responsiveness remain insufficiently understood.
Methods: Kinase activity was characterized during the progression of adiposity across five adipose tissue depots in obese versus lean mice using the advanced PamGene kinome technology. Furthermore, kinase pathways in human preadipocytes and mouse 3T3-L1 preadipocytes were analyzed and compared with those in their differentiated, mature adipocytes. The …

Effects Of Rnai Of Ribophorin 1, Eukaryotic Translation Initiation Factor 2 Beta, And Peptidylprolyl Isomerase A In Acyrthosiphon Pisum, Brandon L. Kennemer
Master's Theses or Doctor of Nursing Practice
Three genes found in the Unfolded protein response, Ribophorin 1, Eukaryotic translation initiation factor 2 beta, and Peptidylprolyl isomerase A are thought to be potential targets for RNA Interference (RNAi) in Acyrthosiphon pisum. Ribophorin 1 (RPN1) is a transmembrane glycoprotein that assists in anchoring ribosomes to the rough endoplasmic reticulum membrane. It acts as a substrate-specific chaperone. It facilitates N-glycosylation by delivering newly synthesized proteins to the oligosaccharyltransferase (OST) complex. Eukaryotic translation initiation factor 2 beta (eIF2B) is a key component of the eIF2 heterotrimer that facilitates protein synthesis initiation by binding GTP and recruiting a specific transfer RNA to …
Buzzes Over Burrows: Bats And Black-Tailed Prairie Dogs In Western Kansas, Patrick L. Geyer
Buzzes Over Burrows: Bats And Black-Tailed Prairie Dogs In Western Kansas, Patrick L. Geyer
Master's Theses or Doctor of Nursing Practice
The native grasslands of the Great Plains and the organisms that inhabit them are threatened by the anthropogenic disturbance of land-use change; prairie dogs (Genus Cynomys) are one such example. These mammals are considered ecosystem engineers due to their behaviors that physically modify the areas they inhabit, directly affecting the resources available to surrounding organisms. Much research exists on established or potential relationships between black-tailed prairie dogs (Cynomys ludovicianus) and other taxa; until recently, one taxon group absent from mentions of an association with black-tailed prairie dogs was bats (Order Chiroptera). Results of acoustic studies in eastern …

Genomic Characterization Of A Novel Bloom-Forming Cyanobacterial Species From Western Kansas., Louisa Acquah
Master's Theses or Doctor of Nursing Practice
Harmful cyanobacterial blooms are a danger to freshwater systems, particularly in water limited regions such as western Kansas, yet the genetic identity and diversity of bloom-forming taxa in this region remain poorly characterized. In this study, I investigated a cyanobacterial bloom in Horsethief Reservoir (Kansas, USA) in summer 2024 with the aim of resolving the taxonomic identity and genomic features of the dominant organism. Bloom water samples were collected, and the dominant cyanobacterium was enriched and rendered nearly axenic through controlled cultivation and repeated subculturing. Preliminary 16S rRNA gene sequencing indicated affiliation with the genus Limnothrix, but with notable …

Exploring The Link Between Soil Microbes, And Land Use Through A One Health Lens, Yaw A. Antwi
Master's Theses or Doctor of Nursing Practice
The diversity of microbes within the soil plays an essential role in soil ecosystem
functioning. However, these microbes may also serve as environmental reservoirs for antibiotic resistance genes. The study examined the diversity of bacteria that are found in soil across Rural/Agricultural and Rural/Nonagricultural landscapes within some selected counties in Kansas and its associated antibiotic resistance genes taxa. A total of twenty-four soil samples was collected and analyzed using 16S rRNA gene amplicon sequencing which targeted the V3-V4 regions. Statistical analysis revealed that the alpha diversity metrics (Chao1 richness and Shannon evenness) showed no significant difference in microbial structure (p=0.693, …
The Role Of Tumor Microenvironment In Glioblastoma Multiforme(Gbm) Therapeutic Resistance, Kwesi E. Taylor
The Role Of Tumor Microenvironment In Glioblastoma Multiforme(Gbm) Therapeutic Resistance, Kwesi E. Taylor
Master's Theses or Doctor of Nursing Practice
Despite significant advances in cancer research and treatment, Glioblastoma multiforme (GBM) remains one of the most difficult cancers to treat effectively, with minimal improvement in long-term survival rates over the past few decades. This is largely attributed to tumor heterogeneity and the ability of tumor cells to develop adaptive resistance mechanisms supported by the tumor microenvironment (TME). Although the TME is recognized as a key contributor to tumor progression and therapeutic resistance, the underlying molecular pathways and regulatory genes remain incompletely understood. This study investigated the role of the tumor microenvironment in GBM therapeutic resistance using a bioinformatics approach. Single-cell …
Floodwater Salinity And Flood Duration Regulate Greenhouse Gas Production In High- Latitude Coastal Wetland And Tundra Soils, Mia J. Dicianna
Floodwater Salinity And Flood Duration Regulate Greenhouse Gas Production In High- Latitude Coastal Wetland And Tundra Soils, Mia J. Dicianna
Electronic Theses and Dissertations
Coastal high-latitude ecosystems are increasingly flooded from storm surges associated with climate change, exposing soils that were historically infrequently inundated to higher-salinity waters for longer durations. Sub-Arctic wetlands and tundra store large amounts of carbon, yet how flooding characteristics, particularly flood duration, influence microbial mineralization and, consequently, greenhouse gas (GHG) production in these soils remains poorly understood. We conducted a full-factorial microcosm incubation experiment in which coastal wetland and tundra soils were subjected to simulated flooding with three durations (1, 3, and 10 days) and four salinity treatments (unflooded, freshwater, 3 ppt, and 12 ppt) and measured carbon dioxide (CO2) …
An Integrated Evaluation Of Trace Mineral Status, Regional Variation, And Supplementation Effects On Circulating Mineral And Reproductive Performance In American Plains Bison, Bailey M. Rodriguez
An Integrated Evaluation Of Trace Mineral Status, Regional Variation, And Supplementation Effects On Circulating Mineral And Reproductive Performance In American Plains Bison, Bailey M. Rodriguez
Electronic Theses and Dissertations
The continued expansion of the American Plains Bison (Bison bison) industry has increased the need for science-based nutritional recommendations tailored specifically to the species, due to limited species-specific research. Because trace minerals influence immune function, growth, and reproductive performance, establishing baseline mineral status and evaluating responses to supplementation are critical for advancing bison production and conservation efforts. This thesis integrates two complementary investigations to evaluate trace mineral status in American Plains bison at both regional and herd management levels. First, a herd level comparison evaluated the influence of differing mineral supplementation strategies on circulating mineral concentrations, herd performance, and reproductive …

Winter-Feeding High Forage Vs. High Concentrate Diets To Beef Cows: Effects On Placental Transcriptomics, Lactation Capacity, And Enteric Methane Emissions, Megan Ann Wehrbein
Electronic Theses and Dissertations
Nutritional management and lactation performance are critical factors influencing productivity in cattle. This research includes two complementary studies. The first study was a meta-analysis to develop a lactation curve for Bos taurus cattle in North America using data from machine or hand milked cows. Data from 7 studies were used resulting in 1340 cow-day observations. Milk yield was analyzed by parity (primiparous or multiparous) and feeding management (non-nutrient restricted or nutrient restricted), revealing that primiparous cattle peaked earlier and at lower yields than multiparous cattle, and nutrient restriction reduced peak milk yield. Overall, Bos taurus cattle followed lactation trends similar …

The Critical Role Of Near-Surface Dynamics In Identifying Spawning Areas Of Atlantic Bluefin Tuna In The Gulf Of Mexico, Donald R. Johnson, William J. Teague, Harriet Perry, James S. Franks
Gulf and Caribbean Research
Atlantic Bluefin Tuna, Thunnus thynnus (ABFT), migrate long distances to broadcast spawn in the Gulf of Mexico (GOM) basin, the Mediterranean Sea and the Slope Sea (NW Atlantic). These areas have commonalities including a highly dynamic upper ocean eddy environment that draws nutrients from shallow thermoclines and adjacent continental shelves and can provide temporal sanctuaries from some larval predators. In the GOM basin, the Loop Current (LC) and its energetic spin—off eddies sweep weak swimming predators such as jellyfish (Pelagia noctiluca) into lines and aggregations, leaving relatively open areas as temporal sanctuaries for ABFT larvae during the vulnerable …

Oyster Drill (Stramonita Haemastoma Complex) Habitat Preferences In A Shallow Coastal Estuary, Coen Mcgarrah, Cynthia Lupton, Eric Sparks, Jennifer L. Debose
Gulf and Caribbean Research
Southern oyster drill snails (Stramonita haemastoma complex) are nuisance organisms within the Gulf of Mexico. This is due to their damaging impact on recovering and farmed oyster (Crassostrea virginica) populations, which are one of the drills’ main food sources. Oyster reef recovery and increased aquaculture production are priorities for Mississippi and the wider northern Gulf coast. The Grand Bay National Estuarine Research Reserve (NERR) hosts multiple oyster reef restoration sites within its boundaries, yet no comprehensive survey of oyster drill abundance has been conducted in this area to date. Additionally, knowledge of oyster drill preferences for sediment …

Between 2006 and 2012, seagrass coverage across Sarasota Bay expanded by 1,108 ha, a 28% increase. During the subsequent years of 2012−2020, 830 ha of seagrass were lost, a 16% decline. In response to these findings, resource management efforts focused on determining the likely reason(s) why those 2 periods had such contrasting trends, to come up with strategies to reverse these losses. Based on results from the seagrass data, the 7—y period of 2006−2012 was designated a “reference period” and water quality data were compared against the subsequent 7—y designated “degraded period” of 2013−2019. Annual average chlorophyll-a (chl-a …

The increasing abundance of ticks poses a growing public health concern due to heightened human exposure to tick bites. The lone star tick (Amblyomma americanum: Ixodida: Ixodidae), a common human-biting species in the United States, has expanded its range in recent years. However, how its different life stages vary across time, habitats, and locations remains insufficiently understood. We analyzed tick abundance data collected in southeastern Virginia between 2009 and 2018, focusing on larval, nymphal, and adult life stages. A Bayesian multivariate modelling framework was used to examine seasonal patterns, habitat effects, spatial variation, and biological links between life stages. Two …

Left In The (Road) Dust: Analyzing Advanced Clean Cars Ii In California’S Disadvantaged Communities, Jj Hoffman
Pomona Senior Theses
Across the United States, air pollution disproportionately impacts minority groups. California’s Advanced Clean Cars II (ACC II) waiver was positioned to lead to significant environmental justice impacts, such as reductions in emissions and adverse health outcomes, by establishing stricter regulations for vehicle emissions and ensuring that 100 percent of new passenger vehicle sales are zero-emission by 2035. As the federal government recently nullified ACC II, pollution, and by extension health, could worsen, especially in disadvantaged communities. The thesis established several important relationships, including how disadvantaged communities experienced higher traffic, pollution, and worse health outcomes than non-disadvantaged communities. Though the results …
