Candidate Interaction Partners Of Calpain-5 Suggest Clues To Its Involvement In Neovascular Inflammatory Vitreoretinopathy, Jozsef Gal, Vimala Bondada, Rachel Crasta, Dorothy E. Croall, Calvin P. Vary, James W. Geddes

Spinal Cord and Brain Injury Research Center Faculty Publications

Although calpain-5/CAPN5 is widely expressed in mammals, little is known regarding its functions. Pathogenic mutations of CAPN5 are causal for a devastating autoimmune eye disease, neovascular inflammatory vitreoretinopathy (NIV). To provide insight into both the physiological and pathological roles of CAPN5, it is essential to identify candidate interaction partners and possible substrates. Human SH-SY5Y neuroblastoma cells, transfected with full-length catalytically dead (Cys81Ala) CAPN5-3×FLAG, were used for anti-FLAG co-immunoprecipitation (co-IP) and quantitative proteomics using Sequential Window Acquisition of all THeoretical mass spectra (SWATH-MS). Fifty-one proteins were enriched at least four-fold, p < 0.01, relative to cells transfected with an empty FLAG vector. A high proportion (24/51) of candidate CAPN5 interaction partners are associated with protein quality control, including components of the chaperonin, chaperone, and ubiquitin–proteasome systems. Additional candidate interactors include tubulins, kinases, phosphatases, G proteins, and mitochondrial proteins. CAPN5 interactions for 14 of the candidate proteins were confirmed by co-IP and immunoblotting. Of these 14 proteins, 11 exhibited in vitro calcium-induced proteolysis following co-IP with WT CAPN5-3×FLAG. Impaired calcium-induced proteolysis of co-IP proteins was observed for the pathogenic CAPN5 variants R243L and R289W. Further studies are needed to validate the association of candidate CAPN5 interactors with proteins and complexes suggested by the SWATH-MS and co-IP results, and the possible role of CAPN5 within such complexes. The possible involvement of CAPN5 in protein quality control is relevant to NIV, as defects in protein quality control have been implicated in inherited retinal disorders. Proteomic data are available via ProteomeXchange with identifier PXD068008.

An Unbiased Molecular Characterization Of Peripartum Cardiomyopathy Hearts Identifies Mast Cell Chymase As A New Diagnostic Candidate, J. F. Mulvey, C. Sailer, J. S. Achter, Gregory Nathaniel Milburn, R. C. Bretherton, K. Kahnert, S. Erbil Bilir, H. Hvid, C. Pyke, F. Gustafsson, L. Adamo, Kenneth S. Campbell, K. M. Herum, A. Lundby

Internal Medicine Faculty Publications

Peripartum cardiomyopathy (PPCM) is a rare form of acute heart failure that develops in women toward the end of pregnancy or early postpartum. No effective, specific treatment for PPCM is available and heart transplantation or mechanical circulatory support may be required in severe cases where drug treatment for heart failure is insufficient. The mechanisms through which the disease progresses are not well understood, and despite similar clinical characteristics to dilated cardiomyopathy of other etiologies (nonperipartum cardiomyopathy; NPCM) it is not known how the molecular remodeling differs between these groups. We aimed to provide insight into the human PPCM heart using …

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 …

Social Engagement Moderates The Relationship Between Cognitive Functioning, Depressive Symptoms, And Restless Sleep In Older Black Adults, Sunkanmi Folorunsho, Olufunmilola Abraham, Darlingtina K. Esiaka

Pharmacy Practice and Science Faculty Publications

INTRODUCTION: Older Black adults face higher dementia risk, but it is unclear whether social engagement offsets the effects of depression and restless sleep.

METHODS: We analyzed 1,905 Black adults aged 50+ from the 2016-2020 Health and Retirement Study (HRS). Linear mixed-effects models tested how depressive symptoms, restless sleep, and social engagement predicted baseline cognition and cognitive decline.

RESULTS: Higher depressive symptoms and restless sleep were associated with lower baseline cognition (about 0.2 and 0.5 points lower) and faster decline (β×time ≈ −0.07 and −0.05). Greater social engagement predicted higher baseline cognition (about 0.6 points higher) and slower decline (β×time ≈ …

Developing Curcumin Analogues For Treating Breast Cancer, Tulasi Laxmi Nutalapati

Theses, Dissertations and Capstones

Breast cancer is still one of the most common types of cancer and one of the most common causes of cancer-related deaths in women around the world. Despite significant advances in early detection and treatment strategies, drug resistance, systemic toxicity, and poor outcomes in aggressive subtypes continue to limit the overall effectiveness of cancer therapy. Natural compounds have become promising anticancer agents because they can target many different things and are not very toxic. Curcumin has shown promise as an anticancer drug, but it cannot be used in the clinic because it does not absorb well, breaks down quickly, and …

Dino-Lg: Enhancing Vision Transformers With Label Guidance For Coronary Artery Calcium Detection, Mahmut Selman Gokmen, Caner Ozcan, Moneera N. Haque, Steve W. Leung, Seth Parker, Brent Seales, Cody Bumgardner

Biomedical Engineering Faculty Publications

Coronary artery disease (CAD), one of the leading causes of mortality worldwide, necessitates effective risk assessment strategies, with coronary artery calcium (CAC) scoring via computed tomography (CT) being a key method for prevention. Traditional methods, primarily based on UNET architectures implemented on pre-built models, face challenges like the scarcity of annotated CT scans containing CAC and imbalanced datasets, leading to reduced performance in segmentation and scoring tasks. In this study, we address these limitations by introducing DINO-LG, a novel label-guided extension of DINO (self-distillation with no labels) that incorporates targeted augmentation on annotated calcified regions during self-supervised pre-training. Our three-stage …

The purpose of this study was to assess the validity and reliability of force insoles in calculating vertical ground reaction force and center of pressure during return-to-sport jump testing. Ten healthy individuals performed double- and single-leg vertical and horizontal jumps on an instrumented treadmill while wearing instrumented force insoles. Vertical ground reaction force and anterior–posterior and medial–lateral center of pressure were collected at peak vertical ground reaction force from both devices. Repeat testing occurred 7 ± 5 days following the …

Non-Contact Optical Spectroscopy For Metabolic And Vascular Characterizations Of Orthotopic Tongue Cancer Models In Vivo, Md Zahid Hasan, Jing Yan, Sumit Sarker, Pranto Soumik Saha, Caigang Zhu

Biomedical Engineering Faculty Publications

Most tissue optical spectroscopy platforms use a fiber probe for light delivery and collection, while the inconsistent probe-sample contact could induce significant distortions in the measured optical signals, which consequently bring analysis errors. Moreover, it will be practically difficult to use a fiber probe for measurements in some cases such as oral cancer investigations using small animal models. To address the critical challenge, we report a portable, lens-based, optical spectroscopy device capable of quantifying key vascular and metabolic parameters in vivo without probe-sample contact. We combined lenses based diffuse reflectance and fluorescence spectroscopy into one portable platform to enable multi-parametric …

Stuart Nelson, Bahman Anvari

Pediatrics Faculty Publications

Objectives: Cryogen spray cooling (CSC) is critical for protecting the epidermis during laser dermatologic procedures. The widely used cryogen, R134a, has a high global warming potential (GWP), motivating interest in environmentally favorable alternatives such as HFO-1234ze. This study evaluated whether HFO-1234ze provides epidermal protection comparable to R134a during laser exposure and investigated the mechanistic basis underlying any differences in cooling performance.

Methods: Laser-induced epidermal injury in conjunction with two cryogens was assessed in K14-SCF Mc1r^e/e mice with pharmacologically controllable interfollicular epidermal pigmentation. Laser treatment sites were assigned fluences relative to baseline skin lightness (L*) to span subthreshold …

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

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 …

The Effects Of Childhood Maltreatment On Executive Functioning: The Difference Between Cumulative Trauma, Abuse Severity, And Neglect, Kelly Krehbiel

Master's Theses or Doctor of Nursing Practice

Childhood maltreatment is prevalent in the United States with around 558,899 children being victims of abuse in 2022 (U.S Department of Health & Human Services, 2024). Neglect is the most common form of abuse with around 74 percent of abused children being neglected; however, neglect tends to be the least researched form of abuse. Childhood maltreatment has long-term effects on a person’s mental, physical, and cognitive health. Previous research suggests that childhood maltreatment leads to severe deficits in executive functioning skills such as working memory and cognitive flexibility. Executive functioning skills are important for almost every aspect of life including …

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

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 …

Examining Obsessive-Compulsive Symptomatology And Maternal Functioning During The Postpartum Period: Implications For Disclosure And Assessment, Meghan Collins

PCOM Psychology Dissertations

Maternal mental health is a significant global health concern, with nearly one in five new mothers experiencing a mental health disorder during the perinatal period. Timely screening, assessment, and treatment are critical for the well-being of both mother and infant, given the potential adverse effects of unaddressed mental health concerns. While much of the existing literature has focused on perinatal depression and anxiety, research specifically examining obsessive-compulsive symptoms and unwanted or intrusive thoughts remains limited. The present study investigated the relationship between obsessive-compulsive symptoms and maternal functioning, as well as experiences related to the assessment and disclosure of intrusive thoughts. …

Lymphedema is a chronic and incurable condition associated with significant physical and psychosocial challenges, including depression, anxiety, social isolation, and reduced quality of life. Despite increasing recognition of these concerns, limited interventions exist that specifically address the psychosocial needs of individuals living with lymphedema. Additionally, individuals within this population often report limited provider awareness of lymphedema within the healthcare system. The purpose of this doctoral capstone project, Harmony in Healing: Addressing the Psychosocial Needs of Individuals Living with Lymphedema, was to promote well-being, improve quality of life, and increase awareness of the psychosocial implications of lymphedema through occupational therapy intervention. …

Sex Equality After Skrmetti, Naomi Schoenbaum

GW Law Faculty Publications & Other Works

The Supreme Court’s decision in United States v. Skrmetti upholding a ban on gender-affirming medical care for minors marked a foundational shift in constitutional sex equality doctrine. Rather than recognize the challenged ban’s sex-based line-drawing, the Court recast the statute as a neutral regulation of medical purpose and age. In so doing, it narrowed the definition of what constitutes a sex-based classification and embraced a conception of biological sex as a natural kind—objective, apolitical, and outside the scope of constitutional scrutiny.

The Article identifies this move as a doctrinal departure and a conceptual reconfiguration. The law’s challengers argued that it …

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

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 …

Evaluating Methodologies For Estimating Enteric Emissions And Modeling Greenfeed Technology Utilization In Extensive Beef And Bison Grazing Systems, Aletta Laura Husmann

Electronic Theses and Dissertations

Greenhouse gas (GHG) emissions from grazing ruminants represent a significant component of U.S. agricultural emissions. However, enteric methane (CH4) from cow– calf systems on extensive rangelands pose substantial measurement and management challenges. The Northern Great Plains (NGP) supports nearly one-quarter of the U.S. beef cow population, yet regionally representative, herd-level enteric emission data from commercial ranches remain limited. This thesis integrates empirical field measurements with modeling approaches to evaluate the feasibility of quantifying enteric emissions on extensive rangelands and to examine system-level drivers influencing data yield, costs, and operational performance. Enteric methane and carbon dioxide (CO2) emissions were measured from …

Constraining The Tectono-Climatic Evolution Of The Northern Rocky Mountains: Insights From Volcanic Glass, Leaf Water, And Leaf Wax Hydrogen Isotopes, Rijumon Nandy

Earth & Environmental Sciences Dissertations

The Eocene-Oligocene period in the North American Cordillera represents a period of great intrigue with complex interactions among tectonics, climate, and surface processes. Although this period is generally associated with synorogenic extension associated with gravitational collapse of the Cordillera, the paleotopographic history remains debated. Existing studies offer conflicting interpretations, suggesting either sustained elevations or modest uplift during this time. Notably, recent reconstructions based on volcanic glass δD values have proposed renewed uplift during the early Oligocene, which needs to be tested with a more extensive and robust dataset. Concurrently, global cooling and aridification during this interval may have been amplified …

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 …
