A Robust Convnext-Based Framework For Efficient, Generalizable, And Explainable Brain Tumor Classification On Mri, Kirti Pant, Pijush Kanti Dutta Pramanik, Zhongming Zhao

Faculty, Staff and Student Publications

Background: Accurate and dependable brain tumor classification from magnetic resonance imaging (MRI) is essential for clinical decision support, yet remains challenging due to inter-dataset variability, heterogeneous tumor appearances, and limited generalization of many deep learning models. Existing studies often rely on single-dataset evaluation, insufficient statistical validation, or lack interpretability, which restricts their clinical reliability and real-world deployment.

Methods: This study proposes a robust brain tumor classification framework based on the ConvNeXt Base architecture. The model is evaluated across three independent MRI datasets comprising four classes-glioma, meningioma, pituitary tumor, and no tumor. Performance is assessed using class-wise and aggregate metrics, including …

A Bovine Cell Line Resistant To Japanese Encephalitis Virus Entry But Permissive To Post-Entry Replication, Sang-Im Yun, Young-Min Lee

Animal, Dairy, and Veterinary Science Faculty Publications

Japanese encephalitis virus (JEV) is a mosquito-borne zoonotic orthoflavivirus that poses a significant global health threat. It causes severe neuroinflammatory disease in humans and reproductive failure in swine. Because of the broad host range and cell tropism of JEV, identifying animal cell lines resistant to infection has been a persistent challenge. In this study, we demonstrate that Madin–Darby bovine kidney (MDBK) cells are resistant to JEV infection yet remain fully permissive to viral replication when transfected with viral genomic RNA. Using immunoblotting, immunofluorescence, and flow cytometry, we show that MDBK cells, unlike the highly susceptible baby hamster kidney (BHK-21) cells …

Association Of Hair Shedding Level With Cow–Calf Performance In Summer-Bred Dexter Cattle, Ichard Browning Jr, Emily G. Hayes, Kaylee S. Hillin, Maria Lenira Leite-Browning

Food and Animal Sciences Faculty Research

Reduced winter hair shedding in beef cows through the spring and summer months may contribute to heat stress and reduced performance in spring-calving herds. This study evaluated the relationship of hair shedding with the fertility and maternal performance of 72 Dexter cows. Hair shedding data for 20 May, 3 June, 17 June, and 1 July in 2019 were used to classify cows as high or low hair shedders. Hair shedding levels were lower (p < 0.05) for 2-year-old cows than for cows 7+ years of age for the first three dates and lower (p ≤ 0.05) for lactating cows than for dry cows on the first two dates. Concurrent and four years of historical performance records were used to assess the associations between hair shedding and cow–calf performance. Data from 230 natural matings in July and August from 2015 to 2019 were analyzed. Birth to weaning weight data were recorded from 2016 to 2019 on 124 spring-born calves. Cow fertility was higher (p < 0.05) for high-shed cows than for low-shed cows for the 1 July classification. When the records from cows that were dry in 2019 were excluded from testing, fertility was higher (p < 0.05) for high-shed cows than for low-shed cows at all four scoring dates. The associations of cow hair shedding levels with preweaning calf performance were minimal. Dexter cows exhibiting higher hair shedding levels in the spring and summer expressed higher summer fertility.

Integrated Proteomics To Understand The Role Of Neuritin-1 (Nrn1) As A Molecular Mediator Of Synaptic Resilience In Alzheimer’S Disease, Derian Pugh

ETDs from 2020-2029

Alzheimer’s disease (AD) is the leading cause of dementia in adults over the age of 65, and currently affects approximately 6.9 million people in the United States. By 2060, the number of people age 65 and older with AD is projected to reach 13.8 million, barring the development of disease-altering therapies to prevent, slow or cure AD. Thus, there is a need for progress in the understanding of AD pathophysiology, as well as in the development of diagnostic and therapeutic interventions. Approximately one-third of individuals without dementia at the time of death are found to harbor high levels of amyloid-beta …

Analysis Of Activated Carbon Fiber (Acf) As Particulate Filtration And Volatile Organic Compound (Voc) Media For The Development Of A Dual-Air Purifying Facepiece Respirator, Brie Mcmahan

ETDs from 2020-2029

Exposure to particulate matter (PM) and volatile organic compounds (VOCs) in occupational or public settings poses adverse health outcomes such as respiratory, cardiovascular, reproductive, neurological, carcinogenic morbidity and mortality. Many occupational settings expose workers to PM and VOC concurrently, yet most commercially available respirators are designed to address either particulates or vapors alone. This includes air-purifying respirators (APRs), powered air-purifying respirators (PAPRs), and filtering facepiece respirators (FFRs) with nuisance-level vapor protection, often limited by bulk, discomfort, high pressure drop, and misuse. We identified a need for alternative dual-exposure media and a respiratory protection device that is lighter, and more comfortable …

The Global Extent Of The Grassland Biome And Implications For The Terrestrial Carbon Sink, A S. Macdougall, B Vanzant, J Sulik, S Bagchi, D Naidu, T O. Muraina, E. Hersch-Green

Michigan Tech Publications

Land cover data are commonly used to model the terrestrial carbon (C) sink, yet these data have wide margins of error that significantly alter estimates of global C storage. Here we demonstrate this data vulnerability in grasslands, which are critical to C cycling but whose estimated distribution has varied by >50 million km (3.5-42% of the Earth's terrestrial surface). Comparing multiple high-resolution land cover products with expertly annotated grassland data from six continents, we show sources of mapping error and discuss C implications based on 2023 United Nations (UN) FAO estimates. Past misidentification arose from inconsistent definitions on grassland identity …

Modulation Of The Cgas-Sting Inflammation Pathway In Mouse Models Of Accelerated And Slowed Aging, Benjamin David Heckman

ETDs from 2020-2029

Chronic sterile inflammation (inflammaging) is a core pillar of aging, and the cGAS-STING innate immune pathway has emerged as a key driver of this process. However, how this pathway intersects with systemic endocrine signaling remains poorly understood. Here, we investigated the intersection of endocrine signaling and cGAS-STING activation using two complementary mouse models with opposing lifespan phenotypes: a short-lived, liver-specific glucagon receptor knockout (LKO) mouse and a long-lived growth hormone-releasing hormone knockout (GHRH-KO) mouse. We demonstrate that despite presenting with a metabolically healthy phenotype, female LKO mice exhibited a significantly reduced lifespan. We link this premature mortality to a sex …

Clinical Decision Support Using Medical Imaging Artificial Intelligence, Yun-Chi Lin

ETDs from 2020-2029

Medical imaging plays a central role in modern clinical decision-making, yet its effective integration with artificial intelligence (AI) remains challenged by real-world clinical constraints. This dissertation investigates how medical imaging-based AI frameworks can be strategically designed to support clinical decision-making for two distinct but clinically critical scenarios: acute pandemic care and chronic neurodegenerative disease management. In acute pandemic settings, such as the COVID-19 crisis, healthcare systems face an urgent need for rapid risk stratification under conditions of data scarcity and operational stress including surges in patient volume and limited medical resources. This work explores strategies for developing deep learning models …

Coexisting Salps Exhibit Distinct Feeding Selectivity On Microorganisms In The North Pacific Subtropical Gyre, Anne W. Thompson, Kylee Lamberson, Kelly R. Sutherland

Biology Faculty Publications and Presentations

Mortality mechanisms play an important role in how oceanic microorganisms contribute to global biogeochemical cycles. Salps are widespread pelagic tunicates known to remove phytoplankton from coastal and high-latitude waters, but their interaction with microorganisms in the vast tropical and subtropical gyres is not well quantified. Using quantitative measurements of six major marine microorganisms in the guts of six distinct but co-occurring salp species from the North Pacific Subtropical Gyre, we examined the impact and dynamics of salp feeding on marine microorganisms in a vast open ocean region. All salps preferentially removed prey greater than 1 μm in diameter, including marine …

Beyond Neurons: Impact Of Cannabidiol On Glial Cells In Ischemic Stroke, Victória Linden De Rezende, Khiany Mathias, Cinara Ludvig Gonçalves, Rafael Mariano De Bitencourt, Tatiana Barichello, Fabricia Petronilho

Faculty, Staff and Student Publications

Ischemic stroke triggers a complex cascade of events involving inflammation, oxidative stress, and glial cell dysfunction, all of which contribute to neuronal damage and impaired recovery. Glial cells (e.g., astrocytes, microglia, and oligodendrocytes) play key roles in neuroinflammatory responses, making them attractive targets for therapeutic modulation. Cannabidiol, a non-psychoactive phytocannabinoid from Cannabis sativa, exhibits anti-inflammatory, antioxidant, and neuroprotective properties. Preclinical evidence indicates that cannabidiol attenuates glial reactivity, reduces pro-inflammatory signaling, mitigates oxidative stress, and preserves blood-brain and intestinal barrier integrity in stroke models. Moreover, cannabidiol modulates key molecular pathways (e.g., nuclear factor-κB, tumor necrosis factor, and calcium-related signaling), contributing to …

Differentiation In The Human Urothelia Is Defined By Distinct Alternative Polyadenylation, Ninh B Le, Surbhi Sona, Briana Santo, Yi Zhang, Rosie Ou, R Allen Schweickart, Veena Kochat, William I Padron, Kunal Rai, Shih-Han Lee, Joo Mi Yi, Oliver Wessely, Byron H Lee, Angela H Ting

Faculty, Staff and Student Publications

Distinct epithelial cell states arise during differentiation, but mechanisms generating transcriptomic diversity among them remain poorly defined. The human ureter urothelium contains basal progenitor, intermediate cells, and terminally differentiated umbrella cells. Prior single-cell RNA sequencing revealed similar global gene expression profiles across these states, raising the question of how distinct identities emerge. Here, we show that alternative cleavage and polyadenylation (APA) introduces a major layer of transcriptomic diversity during urothelial differentiation, largely independent of changes in mRNA levels. Analysis of 13,544 urothelial cells identified hundreds of differentiation-associated APA events. Single-cell imaging revealed spatially specific APA patterns, and reporter assays demonstrated …

Blinking Without Eyelids: First Video-Documented Evidence Of A Blink-Like Reflex In Ophisops Elegans (Reptilia: Lacertidae), Turan Meri̇ç Çelebi̇, Yusuf Çeli̇kaği, Tuana Kinay, Arda Cem Kuyucu, Muammer Kurnaz, Mehmet Kürşat Şahi̇n

Turkish Journal of Zoology

Eyelids play a crucial role in protecting the eyes of vertebrates; however, certain  reptile species, such as Ophisops elegans, completely lack movable eyelids. In this  study, we present the first video-documented evidence of a blink-like reflex in O.  elegans, captured through endoscopic field observations and corroborated by laboratory video analysis. The observed movement consisted of a brief convex  deformation of the ocular surface, lasting approximately 0.3 s and resembling a blink  despite the presence of a fixed transparent brille. This behavior was observed once in  the field and twice under controlled laboratory conditions. We propose that O.  elegans may employ …

Habitat Diversity Or Altitudinal Gradient? Which Factor Better Explains Ground Beetle (Coleoptera: Carabidae) Biodiversity? A Case Study From Davraz Mountain (Isparta, Türkiye), Ebru Ceren Fi̇dan, Ali̇ Gök

Turkish Journal of Zoology

Ground beetle (Carabidae) species diversity and spatial distribution were surveyed  across five habitat types along an elevational gradient on Davraz Mountain, a  biogeographical transition area in southwestern Türkiye. The analyses showed that  habitat heterogeneity—particularly soil moisture and texture—exerts a stronger  influence on carabid diversity than elevation. Sørensen’s and Jaccard similarity  indices showed strong faunal overlap between some sampling areas, while  multivariate principal components and canonical correspondence analyses verified  distinct environmental gradients influencing community structure. Diversity indices  indicated varying levels of species richness and evenness across sampling areas.  The data highlight the importance of fine-scaled habitat features in driving ground  beetle …

All Peer-Reviewed Publications

Human activities, either intentional or unintentional, have significantly influenced the global distribution and genetic composition of many species. The black soldier fly (Hermetia illucens; BSF) is a species native to North America that has rapidly gained commercial importance due to its bioconversion efficiency, upcycling organic waste into higher-value products. Through human-mediated dispersal associated with trade and insect farming, BSF has been introduced widely across the Old World, including Africa, where both wild and captive populations are now established. Despite its expanding global distribution, the demographic history and genomic consequences of these introductions remain poorly understood, particularly in Africa. This work …

Agronomic, Nitrogen Use, And Economic Efficiency Of Winter Wheat (Triticum Aestivum L.) Under Variable-Rate Versus Uniform Nitrogen Fertilization, Judith Ntow Oppong, Clement Elumpe Akumu, Felix Ogunmokun, Stephanie Anyanwu, Chaz Hardy

Agricultural and Environmental Sciences Faculty Research

Efficient nitrogen (N) management is essential for sustaining crop productivity while minimizing environmental impacts associated with excessive fertilizer use. Variable-rate application (VRA) offers a precision-based approach to matching N inputs with crop demand, yet winter wheat responses to reduced N rates are still underexplored. This study evaluated winter wheat (Triticum aestivum L.) performance under variable and uniform N application strategies using canopy greenness (NDVI), grain yield, plant N content, nitrogen use efficiency (NUE), and fertilizer costs as indicators. Reduced N treatments (40% and 60% VRA rates) were compared with a uniform (100%) application. Canopy greenness increased across all treatments over …
