Utilizing The K18-Hace2 Mouse Model To Develop Protective Covid-19 Vaccines, Ting Y. Wong

Graduate Theses, Dissertations, and Problem Reports (ETD)

The ongoing Coronavirus Disease 2019 (COVID-19) pandemic is caused by the respiratory virus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Similar to other respiratory viruses, SARS-CoV-2 is transmitted through inhalation of respiratory droplets and aerosols from infected individuals. Once inhaled, SARS-CoV-2 utilizes the receptor binding domain (RBD) on the spike protein to bind to human Angiotensin Converting Enzyme 2 (hACE2) receptor to gain entrance into host cells to begin viral replication. SARS-CoV-2 infection can result in mild to severe cases of COVID-19 ranging from asymptomatic infections, cold or flu like symptoms to respiratory failure. The onset of the pandemic in …

Small Mammal Communities Of Restored And Natural Wetlands In West Virginia, Krista Noe

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wetland restoration is commonly practiced as part of conservation programs or wetland mitigation, which attempts to offset human-created losses of natural wetlands. However, because of the intrinsic and human-derived value of wetlands, it is critical to determine whether these wetlands truly act similarly to natural wetlands. One role of wetlands is to provide habitat for a diverse array of wildlife species. Small mammals are often overlooked taxa in wetland restoration efforts. However, they are essential to the wetland system because they influence vegetation and are prey for higher trophic level wildlife. I discuss considerations of restored wetlands, wildlife responses to …

Transitions Between The Steps Of Group Iic Intron Forward And Reverse Splicing And Integration Into Dna, Claire Mae Smathers

Graduate Theses, Dissertations, and Problem Reports (ETD)

Group II introns are ancient ribozymes capable of self-excision and mobility into new genomic locations. As the ancestors of both the eukaryotic spliceosome and eukaryotic retroelements, these simple RNA machines serve as excellent models for understanding the mechanisms of both gene splicing and retroelement activity in eukaryotes. Although group II introns have been studied for decades, knowledge of the most unique and arguably evolutionarily relevant class of group II introns, IIC, is limited. Our knowledge is especially limited in terms of understanding how IIC introns mediate the transition between the two transesterification steps of forward splicing and reverse splicing into …

Phenomic And Genetic Controls Of The Drought Stress Response In Sorghum, Melissa A. Lehrer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Drought, one of the most common abiotic stressors, is a result of the precipitation and temperature fluctuations influenced by climate change. As consistent weather patterns are crucial for the maintenance of crop yield, drought threatens food security through its impact on plant growth and development. It is essential to ensure the quality, availability, and affordability of grain-based products in the face of climate change due to expectations of population growth. Therefore, shedding light on the mechanisms associated with drought tolerance is integral to maintaining agricultural production under water-limited conditions. My dissertation work aimed to uncover the morphological, physiological, and genetic …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Triple-wash with a mixture of peroxyacetic acid and H2O2 (SaniDate-5.0) during post-harvest processing of fresh produce has been recommended by West Virginia Small Farm Center to improve microbial safety. It has been well recognized that the washing of produce is more important for preventing cross-contamination than reducing foodborne pathogens. Furthermore, it may help improve public confidence in that the produce they obtain from locally grown farmers is safe for their consumption. determine the efficacy of SaniDate-5.0 for reducing the survival and preventing cross-contamination of the Salmonella surrogate Enterococcus faecium on tomatoes during triple-wash.

E. faecium ATCC-8459 (resistant to 100-ppm nalidixic-acid) …

Exploiting Modulation Of The Blood-Brain And Blood-Tumor Barrier Permeability By Translational Focused Ultrasound For Therapeutic Delivery To Cns Metastases, Tasneem A. Arsiwala

Graduate Theses, Dissertations, and Problem Reports (ETD)

Transcranial low-intensity focused ultrasound is a unique technology to modulate the integrity of tight endothelial junctions and transiently increase BBB/BTB permeability to enhance therapeutic delivery. Despite promising early studies, present literature lacks agreement on key experimental conditions, which restricts our knowledge and the technique's widespread translation. This dissertation first provides a critical review of the current gaps in knowledge regarding the universal use of LiFUS in preclinical and clinical use. We then identify key parameters for translational and predictable opening of the BBB using a 3T MRI coupled with a clinical device. Our investigation highlights that passive permeability of the …

A Novel Computational Network Methodology For Discovery Of Biomarkers And Therapeutic Targets, Qing Ye

Graduate Theses, Dissertations, and Problem Reports (ETD)

Lung cancer has the second highest cancer incidence rate and the top cancer-related mortality worldwide. An estimate from the American Cancer Society shows that, in 2022, there will be about 236,740 lung cancer cases (117,910 men and 118,830 women) in the US. To date, there are no prognostic/predictive biomarkers to select chemotherapy, immunotherapy, and radiotherapy in individual non-small cell lung cancer (NSCLC) patients. There is an unmet clinical need to identify patients with early-stage NSCLC who are likely to develop recurrence and to predict their therapeutic responses. This dissertation developed a novel computational methodology for modeling molecular gene association networks …

The Musashi Rna Binding Proteins Are Regulators Of Alternative Splicing And Protein Expression In Photoreceptor Cells, Fatimah Kh. Matalkah

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Musashi (Msi) family of RNA binding proteins consists of two paralogs, Msi1 and Msi2, that are highly conserved across species. The two paralogs have emerged as factors that promote stem cell proliferation by post-transcriptionally regulating translation. In addition to their expression in stem cells, the Musashi proteins are also expressed in postmitotic neurons, including the photoreceptor cells. The Musashi proteins have been observed to maintain high expression levels in the postmitotic photoreceptors within the eye of both invertebrates and vertebrates. These observations suggest an additional role in the maintenance of terminally differentiated neurons.

Building upon these observations, we investigated …

Mechanistic Insight Into Chronic Stress-Induced Cerebrovascular Dysfunction, Emily Nicole Burrage

Graduate Theses, Dissertations, and Problem Reports (ETD)

Despite decades of research psychological stress remains a prevalent problem in society, often diminishing quality of life and increasing the risk of developing dementia. The brain plays a central role in the response to stress and as it is unable to store energy substrates, the brain relies heavily on dynamically regulated blood flow. Therefore, it is important that there is a tight coupling between neural activity and cerebral blood flow to meet metabolic demands and maintain critical brain function. It has been established that chronic psychological stress has detrimental effects on cerebrovascular function, potentially through increased superoxide anion production through …

Examining Development And Function Of Pretectal Visual Neural Circuits In Gs Homeobox 1 Mutant Zebrafish, Alexandra Rose Schmidt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Brain development requires a coordinated genetic code to regulate initial cell identity determination, migration, and connectivity, to establish function of neural circuits. Independent neural circuits underlie our ability to produce both complex and innate behavioral responses to sensory stimuli that are often conserved across vertebrate organisms. Sensory processing disruptions are associated with several neurodevelopmental disorders (NDDs). Therefore, gene mutations altering neurodevelopment can lead to changes influencing structure and function of individual neural circuits, causing behavioral deviations in sensory responsiveness. Crucial gene networks that define functional properties of sensory domains are often explored using non-mammalian vertebrate models, such as the zebrafish. …

Investigating The Interplay Of The Immune System, Skin Barrier, And Microbiome Following Dermal Exposure To Triclosan, Rachel Baur

Graduate Theses, Dissertations, and Problem Reports (ETD)

Triclosan is an antimicrobial chemical used in healthcare products that are applied to the skin. However, exposure to triclosan has been positively associated with food allergy, aeroallergy, and asthma severity in humans. In mice, dermal triclosan exposure, although not directly sensitizing, has been shown to augment the allergic response in a model of asthma. Furthermore, exposure to triclosan on mouse skin has been demonstrated to be immunomodulatory through the activity of thymic stromal lymphopoietin and S100 calcium-binding protein A8. The skin barrier and microbiome are known to interact with the immune system and disruptions in barrier integrity and the microbiome …

Aging, A Pathological Factor In Neurological Injury, Aruvi Vijikumar

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the main reasons for CNS drugs to fail in clinical development is not considering age as a risk factor while studying chronic age-related neurological/neurodegenerative diseases in preclinical studies. We first set out to gain a comprehensive understanding of the impact of age on various aspects (anatomical, immunological, and biochemical) in rodents that play a key role in determining the onset, progression, and evolution of disease severity. With advancing age, the vascular structure and function are compromised which is hypothesized to accelerate cognitive decline. The initial step toward developing novel therapeutics is to characterize the age-related vascular modifications. Utilizing …

Reproductive Rates, Kitten Survival, And Den Site Selection Of Bobcats (Lynx Rufus) In The Black Hills, South Dakota, Erin E. Morrison

Graduate Theses, Dissertations, and Problem Reports (ETD)

The bobcat (Lynx rufus) is an important furbearer in South Dakota. However, management of bobcats can be difficult because of their elusive nature and lack of demographic information. In particular, managers lack information on abundance, survival, and reproductive rates necessary to ensure sustainable harvests and stable populations through time. Additionally, cause-specific mortality can provide insight into the factors influencing bobcat kitten survival rates, as well as reveal actions managers could take to improve survival. Bobcat resource selection can vary depending on spatial scale and it is important to understand how denning may result in different selection patterns at …

Actin Cytoskeletal Regulation And Matrix Metalloproteinase Targeting In Head And Neck Squamous Cell Carcinoma (Hnscc) Progression, Jessica Lea Allen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Head and neck squamous cell carcinoma (HNSCC) is a cancer originating from the epithelial lining of the oral cavity, larynx, and pharynx. HNSCC is associated with extensive locoregional invasion and tissue destruction. Invasive processes underlying HNSCC contribute to poor prognosis and decreased quality of life. Amplification of chromosome 11q13 is the most common DNA aberration in human papilloma virus negative (HPV^-) HNSCC. This region includes various genes known to drive tumor progression. CORO1B (coronin 1B) flanks the core 11q13 region and is amplified in 7-14% of HNSCC. Coronin 1B is essential for mesenchymal cell motility by promoting turnover …

Internalization Of Appearance Ideals And Not Religiosity Indirectly Impacts The Relationship Between Acculturation And Disordered Eating Risk In South And Southeastern Asian Women Living In The United States, Sonakshi Negi, Erik M. Benau, Megan Strowger, Anne Claire Grammer, C. Alix Timko

Psychology Faculty Publications

Objective: Studies that examine disordered eating in samples of Asian individuals living in the United States frequently combine all individuals of Asian descent into a single group, which can obscure important differences between groups and their experiences of acculturation. The goal of the present study was to establish the relation of acculturation, internalization of appearance ideals, and religiosity as predicting body dissatisfaction and disordered eating in women of South and Southeast Asian (SSEA) descent.

Method: Women of SSEA descent (N = 112) aged 18–51 years (M = 23.10, SD = 6.4) completed a battery of questionnaires that inquire about these …

Bartley, Rosario Pintos Lobo, Lauren D. Hill-Bowen, Taylor Sato, Erica D. Musser, Matthew T. Sutherland, Angela R. Laird

Psychology Faculty Publications

Background: Post-traumatic stress disorder (PTSD) is a debilitating disorder defined by the onset of intrusive, avoidant, negative cognitive or affective, and/or hyperarousal symptoms after witnessing or experiencing a traumatic event. Previous voxel-based morphometry studies have provided insight into structural brain alterations associated with PTSD with notable heterogeneity across these studies. Furthermore, how structural alterations may be associated with brain function, as measured by task-free and task-based functional connectivity, remains to be elucidated.

Methods: Using emergent meta-analytic techniques, we sought to first identify a consensus of structural alterations in PTSD using the anatomical likelihood estimation (ALE) approach. Next, we generated functional …

For Whom The Bell Tolls: Psychopathological And Neurobiological Correlates Of The Dna Methylation Index Of Time-To-Death, Sage E. Hawn, Xiang Zhao, Danielle R. Sullivan, Mark Logue, Dana Fein-Schaffer, William Milberg, Regina Mcglinchey, Mark W. Miller, Erika J. Wolf

Psychology Faculty Publications

Psychopathology is a risk factor for accelerated biological aging and early mortality. We examined associations between broad underlying dimensions of psychopathology (reflecting internalizing and externalizing psychiatric symptoms), PTSD, and age-adjusted GrimAge (“GrimAge residuals”), a DNA methylation biomarker of mortality risk relative to age. We also examined neurobiological correlates of GrimAge residuals, including neurocognitive functioning, blood-based biomarkers (of inflammation, neuropathology, metabolic disease), and cortical thickness. Data from two independent trauma-exposed military cohorts (n = 647 [62.9% male, M_age = 52], n = 434 [90% male, M_age = 32]) were evaluated using linear regression models to test associations between …

Rationale And Design Of An Ecological Momentary Assessment Study Examining Predictors Of Binge Eating Among Sexual Minority And Heterosexual Young Women: Protocol For The Health And Experiences In Real Life (Her Life) Study, Kristin E. Heron, Abby L. Braitman, Charlotte A. Dawson, Cassidy M. Sandoval, Lauren V. Butler, Alicia Moulder, Robin J. Lewis

Psychology Faculty Publications

Background: Previous research has identified health disparities between sexual minority and heterosexual women, including increased rates of obesity and binge eating in sexual minority women. Established predictors of binge eating behavior include negative emotions and sociocultural processes; however, these studies are generally conducted in samples of young women where sexual identity is not known or reported. There is a dearth of research evaluating how sexual minority–specific factors (eg, minority stress and connectedness to the lesbian, gay, bisexual, transgender, and queer community) may affect binge eating in sexual minority women. In addition, no studies have examined these processes in racially diverse …

Smallmouth Bass (Micropterus Dolomieu) Population Characteristics And An Evaluation Of Management Responses In Two West Virginia Watersheds, Jacob D. Harrell

Graduate Theses, Dissertations, and Problem Reports (ETD)

Smallmouth Bass (Micropterus dolomieu) population characteristics were examined within the Tygart and Cheat River watersheds of north-central West Virginia. Growth, mortality and recruitment were examined for each individual population prior to modeling potential effects of various management schemes. Smallmouth Bass were sampled for total length and weight, aged using sagittal otoliths and sexed through observations of gonadal or ovarian development. Growth for each population was examined using von Bertalanffy growth models and assessed for variation among populations. Population demographic characteristics differed between and among populations, most noticeably between riverine and lacustrine habitat, whereby growth, mortality and recruitment were higher …

Assessment Of The Geographic Distribution And Tools To Assist With Conservation Of Spotted Turtles (Clemmys Guttata) In West Virginia, Joel Leal Mota

Graduate Theses, Dissertations, and Problem Reports (ETD)

Turtles are one of the most globally threatened vertebrate groups, largely due to habitat loss, commercial exploitation, climate change, disease, and invasive species. In the United States, the spotted turtle (Clemmys guttata) is among over 50 amphibian and reptile species recently petitioned to be listed under the Endangered Species Act of 1973 (ESA). The U.S. Fish and Wildlife Service subsequently determined the spotted turtle to be a candidate species for listing. Historically, spotted turtles were known to occur at a few locations in the eastern panhandle region of West Virginia. However, previous attempts to determine the distributional extent …

Summer Habitat Use, Home Range, And Effect Of Catch And Release Mortality On The Trophy Potential Of Muskellunge, (Esox Masquinongy, Mitchill, 1824), In A Southern Reservoir Population, Peter Isaac Jenkins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Research on Muskellunge (Esox masquinongy, Mitchill, 1824) catch-and-release mortality has been historically focused on the Midwest, Great Lakes, and Ontario. In the southern portion of their range, which we consider to be the portion of the species distribution south of the Mason-Dixon Line (~40°N), Muskellunge, may experience significantly warmer temperatures than those in previous studies and anglers have expressed concern about summer catch-and-release mortality. As part of a broader study to quantify catch-and-release summer mortality in the southern range of Muskellunge, we utilized radio telemetry and active tracking to verify individual movement and survival of Muskellunge in Stonewall …

Ecology Of Black-Legged Ticks (Ixodes Scapularis) At Fort Drum Military Installation, New York, Lucas Eli Price

Graduate Theses, Dissertations, and Problem Reports (ETD)

The number of confirmed cases of Lyme disease in the United States of America has risen from 12,801 cases reported in 1997, which is the earliest year these data are available, to 23,453 confirmed cases in 2019. In the eastern United States, black-legged ticks (Ixodes scapularis) are the primary vector of Lyme disease, which is caused by the spirochete bacterium, Borrelia burgdorferi. Tick abundance tends to be highest in dense forest habitats and where wildlife diversity is low. Because wildlife species have varying levels of competency as reservoir hosts, sources of tick bloodmeals influence Lyme disease ecology. …

Genetic Underpinnings Of Novel Trait Development In A Euwallacea-Fusarium Mutualism, Elaina J. Spahr

Graduate Theses, Dissertations, and Problem Reports (ETD)

Evolutionary Developmental Biology seeks to answer fundamental questions about the mechanisms underlying the evolution and innovation towards increasing structural complexity within the body plan. The ambrosia symbiosis, a polyphyletic group of xylem-feeding beetles, provides a wealth of diversity in novel pouch-like structures called mycangia. This diversity could serve as a rich model for understanding how mutualisms may prompt structural innovation and diversification in a host organism. The ambrosia symbiosis has become a fast-growing research subject in entomology and forest pathology but has yet to experience the same attention under the lens of evolutionary developmental genetics.

Development of mycangia was examined …

Factors Influencing Brook Trout Population Dynamics And Resilience In Central Appalachian Headwater Streams, Christopher W. Schwinghamer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Central Appalachia has a unique history of human perturbation due largely to its historical economic reliance on extractive industry and timber harvest. Legacy impacts from these historic disturbances along with contemporary stressors in the form of continued industry, changing climates, altered land use, habitat fragmentation, and introduced species can present great threats to the region’s aquatic ecosystems. Brook Trout Salvelinus fontinalis are a species that has recreational and economic importance to the communities of central Appalachia but declines in size and abundance have been observed. Given the disturbances that threaten Brook Trout populations, understanding how their populations will respond to …

Analyzing The Viability Of Direct Pcr For Use In Conjunction With Cyanoacrylate Enhanced Fingerprints, Coral M. Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Efficient methods for DNA analysis are desperately needed in laboratories due to the influx in DNA analysis requests. The current DNA processing methods are costly, time consuming, and involve multiple tube changes, increasing the risk of contamination. However, the use of direct PCR can simplify the DNA analysis process by eliminating the extraction, purification and quantitation steps. Presently, the FBI Quality Assurance Standard 9.4 requires all evidence samples to be quantitated. As a result, the direct PCR method of DNA processing cannot be implemented on evidence samples at this time. Direct PCR presents the opportunity to provide efficient DNA analysis, …

Mtdna Heteroplasmy In Hair Shafts Versus Buccal Swabs For Forensic Applications, Sara R. Bodnar

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mitochondrial DNA (mtDNA) analysis has several forensic applications such as criminal investigations, identification of human remains, and missing person investigations. It is also the only type of DNA that is available from certain sample types such as hair shafts. The presence of mtDNA heteroplasmy within and between tissue types can lead to mtDNA sequence differences when comparing samples originating from the same individual. Studies on mtDNA heteroplasmy are increasingly being carried out for their implications in forensic interpretation of mtDNA sequences. Specifically, mtDNA in buccal swabs compared to hair samples from one individual may show differences in sequence due to …

Evaluating Muskellunge (Esox Masquinongy) Catch-And-Release Mortality At Elevated Summer Water Temperature, Ian Taylor Booth

Graduate Theses, Dissertations, and Problem Reports (ETD)

Angling for Muskellunge (Esox masquinongy) has become widespread and increasingly popular throughout the fish’s range. Current management strategies for Muskellunge include high minimum harvest lengths (>1016mm), closed seasons, and catch-and-release regulations. Due to these strategies and angler sentiments, up to 97% of Muskellunge caught today are released by anglers assuming they will live and be caught again in the future. Previous research on catchand-release mortality in Muskellunge has suggested relatively low mortality rates (0%-5%). However, these studies were all conducted within the fish’s thermal optimum and generally at water temperatures25°C during the summer months, representing a need to evaluate …
