Despite the promise of immune checkpoint blockade (ICB) in head and neck squamous cell carcinoma (HNSCC), mediators of response are poorly understood. To address this, here we analyzed oropharyngeal HNSCCs treated with neoadjuvant durvalumab (anti-PDL1) alone or in combination with tremelimumab (anti-CTLA4) from the CIAO clinical trial ( NCT03144778 ). We found that only the total abundance of intratumoral bacteria predicted ICB response, which was validated in multiple independent cohorts. High intratumoral bacteria abundance was associated with an immunosuppressive tumor microenvironment, characterized by an accumulation of neutrophils coupled with depletion of T cells and other adaptive immune cells. Experimental elevation …

Meat Is Dead, Melissa D. Mortazavi

Faculty Articles

The legal and cultural landscape surrounding meat in the United States is evolving as plant-based alternatives, GMO farm animals, and cell-cultivated meat move from test tube to table. While global demand for meat rises amid environmental, ethical, and resource challenges, cell-cultivated meat emerges as a scientifically viable alternative, offering identical nutritional value without the drawbacks of conventional livestock production. Despite federal regulatory approval from USDA and FDA, multiple states have enacted unusually restrictive laws—including bans— targeting cell-cultivated meat. These are motivated largely by economic protectionism, but also deeper cultural anxieties tied to tradition and identity. This Article argues that food …

When To Bite Back: Queerness, Resistance, And Reclamation Of The Monstrous Identity In Andrew Joseph White’S Hell Followed With Us, Aster J. Mehigan Mx.

English

Who gets the right to define morality? Who gets to define what is monstrous? Frankenstein’s Creature, the vampires of Lost Boys, The Craft’s head witch Nancy Downs; these characters follow a pattern through the decades of those alienated from society, in this case being written with queer subtext, being deemed as monstrous. These queer monsters become the villains of the story, causing chaos, death and destruction in their wake, seeking revenge against a world that ostracizes them. The 2022 dystopian YA horror of Hell Followed With Us by Andrew Joseph White challenges the villanized monstrous identity through its transgender protagonist …

Dog Waste Creates A Preference-Performance Mismatch For Urban Dung Beetles, Erin L. Mccullough, Beatrice M. Altopp, Daniel F. Kellogg, Madelyn S. Mcinnis, Luna J. Pagan

Biology

Urban environments expose animals to novel conditions that may favor behavioral flexibility but can create preference-performance mismatches when attractive resources are associated with reduced reproductive success. Dung beetles are often considered dietary generalists, yet little is known about how they respond to altered food availability in human-dominated habitats. We combined field surveys and laboratory experiments using two domestic dung types to examine diet preference, maternal provisioning, and offspring performance in the urban dung beetle Onthophagus orpheus. Beetles strongly preferred dog dung over cow dung, and offspring reared on dog dung developed faster and emerged as larger adults. Despite these apparent …

Clinical Challenges Associated With Enhancing Hypertension Among The Underserved African American Population, Ashley Richardson

Doctor of Nursing Practice (DNP) Scholarly Projects

Background 

African Americans face a significantly higher prevalence of hypertension, tend to develop complications at younger ages, and have disproportionately higher mortality rates. Key social determinants of health (SDoH)—including food deserts, unequal access to healthcare, and geographic disparities in healthcare resources—contribute to these ongoing inequities. Addressing both systemic and individual barriers is crucial for effective hypertension management.

Objective

This study aims to assess the effectiveness of a culturally relevant, community-based intervention designed to reduce both systolic and diastolic blood pressure among Black adults with uncontrolled hypertension.

Biological Sciences Faculty Publications

Postsynaptic scaffolding protein SAP90/PSD95-associated protein 3 (SAPAP3) modulates cortico-striatal signalling and regulates the maintenance of synaptic structure. Notably, SAPAP3 defects have been reported in several human psychiatric disorders that share pathophysiological features with Huntington’s disease (HD), a neurodegenerative disorder characterized by the expression of mutant huntingtin (mHTT) and marked dysfunction of cortico-striatal synapses and mitochondria. However, the role of SAPAP3 in mitochondrial function and HD pathophysiology remains unexplored. SAPAP3 was extracted from striatal synaptoneurosomes and analyzed by SWATH-MS proteomics to identify potential interactors, revealing SAPAP3 association with several mitochondrial proteins, particularly Mic60. These data were further complemented with proximity ligation …

Rhetoric Of Opportunity: An Analysis Of Gullah Geechee Histories Through The Lens Of Counterstory, Xaria Arthur

Graduate Studies Theses and Dissertations 2026

Counterstory as a method/ology has been used in a variety of disciplines to share experiences of individuals and communities whose voices have been historically silenced or suppressed. Utilizing this methodological framework, my study shares the stories of six Gullah Geechee descendants with ancestral roots in the unincorporated community of Nesmith in Williamsburg County, SC. Treating these minoritized and individual stories as experiential knowledge, I trace the counterstories as topoi to introduce and develop the theoretical concept that I call the rhetoric of opportunity, which refers to memories or stories that have come to motivate individuals toward or away from …

It's All The Same, Lauren A. Bedevia

Graduate Studies Theses and Dissertations 2026

It’s All the Same is a collection of short stories that center around lesbian characters. The stories explore themes such as ambition, morality, karma, mental health, exploitation, and relationships. The collection opens with “Forget Her Inc.,” a short story that juggles an ensemble cast of lesbians and examines whether memory eraser therapy is an ethical practice for treating a broken heart. “It’s All the Same,” the titular story, uses lyricism to present the parallels between two women in terms of family dynamics, interests, and attachment styles; the story explores a loving friendship between a lesbian and a straight woman.

Carbaryl Exposure Alters Gut Microbiome Composition Without Affecting Morphometrics In Eastern Purple Martin (Progne Subis Subis) Nestlings, Stephanie A. Gaspar

Graduate Studies Theses and Dissertations 2026

Eastern purple martins (Progne subis subis) rely entirely on human-provided nesting structures throughout their breeding range in eastern North America. To control haematophagous mites that commonly infest these nests, many landlords apply the carbamate insecticide, carbaryl. Although effective at reducing ectoparasite populations, carbaryl exposure may have unintended effects on the gut microbiome, growth, and condition of developing birds. This study examined the effects of carbaryl exposure on gut microbial communities and morphometric condition in wild nestlings. Nests were experimentally treated with carbaryl, and nestling morphometrics and fecal microbiomes were compared between treated and untreated groups at 18 days …

How To Stop Mass Shootings Without Violating The Second Amendment: Designing Regulations To Prevent Acts Of Mass Violence That Pass The 6:3 History And Tradition Test, Robert D'Alessandro

Cardozo Journal of Equal Rights & Social Justice

The article proposes that states can constitutionally implement ammunition possession limits to reduce mass violence by aligning such laws with the "history and tradition" test established by the current Supreme Court. It argues that modern caps on ammunition are analogous to early American gunpowder restrictions, which were enacted for public safety to prevent catastrophic explosions in populated areas.

The Inward Gaze: Byung-Chul Han's Achievement-Subjectivity In David Foster Wallace's Short Fiction, Ivan Marquez

All Student Theses and Dissertations

David Foster Wallace stated that the aim of his fiction and art was to reflect what it meant to be alive and form a relationship with the reader. In "E Unibus Plurum", Wallace posited that the tenets of Post-Modern fiction were once used to criticize the hypocrisies of the 1950's and 60's American had been subsumed by television and were no longer effective tools of criticism. Wallace argues for a move away from irony and stunt pilotry of postmodern fiction towards a fiction which espoused "single entendre values" (Wallace 192). While Wallace advocated for a return to more traditional story-telling, …

Investigating The Potential Neurotoxic Effects Of Cell-Free Factors By Batrachochytrium Dendrobatidis On Locomotion In Xenopus Laevis, Anna Lennon, Laura K. Reinert, Louise A. Rollins-Smith, Will Best, Chase T. Kinsey Phd

Funded Scholarship

Chytridiomycosis is a contributor to amphibian population declines. Diseased amphibians show symptoms of lethargy and loss of righting reflexes, likely due to ion imbalance across the skin. However, it is possible developing zoosporangia release toxins that affect neuromuscular activity. Using Xenopus laevis as a model, we hypothesized that locomotor performance would be affected by injection of Bd supernatant factors. X. laevis were injected and then filmed performing a swimming escape response with high-speed cameras at 4 hours, 24 hours, and 1- week post-injection. Average maximum swimming velocity and escape latency were digitized using high speed video. Despite no difference in …

“Being Treated As The Expert:” A Blueprint For A Community Advisory Board Approach To Elevate The Voice Of People With Living Experience With Substance Use In Academic Research, Trevor Moffitt, Survivors Union Of The Bluegrass, Bryson Henson, April M. Young, Sharon L. Walsh, Rachel Vickers-Smith, Junior Cruz, Jeremy Byard, Brook West, Amanda Fallin-Bennett

Nursing Faculty Publications

Introduction: Researchers have traditionally engaged Community Advisory Boards (CABs) to meaningfully involve community members in the research process. However, CABs are often formed only after a grant is funded, leading to criticisms of functioning merely as “ethical approvers.” For substance use researchers, the inclusion of people with living experience (PWLE; current experience with drug use) across all stages of research is especially important as they have historically been the experts in the needs of their community.   Methods: In response to this need for community engagement in research, the University of Kentucky, in partnership with a local recovery community center (RCC; …

Comparison Of Enrichment Interaction Duration Between Male And Female Panthera Leo Leo, Maegen G. Meldrum

Undergraduate Honors Thesis Projects

African lion (Panthera leo leo) populations have declined significantly over the past century within their natural habitats, increasing the importance of effective management strategies for individuals in human care. Environment enrichment is a critical tool for promoting species typical behavior in human care; however, enrichment practices are often generalized and may not account for sex-specific differences. This study examined how sex, enrichment types, behaviors, and time of day influenced enrichment interaction duration in a small pride of African lions (n = 4) housed at the Columbus Zoo and Aquarium. Two enrichment types were evaluated: cognitive/occupational (CO, a manipulable barrel) …
