Satisfaction With Physician Communication, Joyce Ho

2026 Research Poster Competition

Problem. Provider-patient communication can be sorted into two approaches: patient-centered communication (PCC) and doctor-centered communication (DCC). PCC is characterized by a patient focus, in which patients are encouraged to participate in decisions regarding their care, while DCC is characterized by a doctor focus, in which the physician acts as an informational source for patients (Bientzle et al. 2017). Physician communication style is known to be influenced by gender. Female physicians are more likely to utilize PCC than their male counterparts (Roter 2004). Female patients are more likely to have higher measures of PCC in interactions with their physicians (Bertakis et …

C/Ebpα Is Essential For Gonadal But Not Inguinal White Adipose Tissue Formation In Mice, Krista Y. Hu, Yu-Lin Ma, Esme A. Dodge, Olivia A. B. Maguire, Caio V. Matias, Ryan K. Barney, Hector S. Himede, Juliana Gomez Pardo, Miriam Cepeda, Scott M. Gordon, Robert C. Bauer

Physiology Faculty Publications

Objective: The distribution of excess white adipose tissue (WAT) in obesity correlates with risk for comorbidities. Thus, understanding depot-specific WAT developmental mechanisms is translationally relevant. SNPs near the gene CEBPA associate with waist to hip ratio, and while C/EBPα is a recognized regulator of adipogenesis, there is no previously known role for C/EBPα in regulating adipose distribution.

Methods: We crossed Cebpa floxed mice to the AdipoQ-Cre transgenic mouse strain, generating mice with adipocyte-specific knockout of Cebpa (Cebpa_ASKO). Mice were phenotyped on a chow diet and after prolonged high-fat diet (HFD) feeding.

Results: Cebpa_ASKO mice almost entirely lack gonadal …

Early Microglial Response To Amyloid Plaques Drives Sleep Loss In Alzheimer’S Disease, Nicholas J. Constantino, Riley E. Irmen, Matthew J. Lanning, Sierra M. Turner, Clair C. Ashley, Caitlin M. Carroll, Evan M. Neary, Dave Rubinow, J. Andy Snipes, Shannon L. Macauley

Physiology Faculty Publications

Introduction: Sleep disruption is an early feature of Alzheimer's disease (AD), but the cellular mechanisms linking amyloid pathology to sleep loss remain unclear.

Methods: Electroencephalography/electromyography (EEG/EMG) recordings, quantitative EEG analysis, and sleep deprivation were performed in APPswe/PSEN1dE9 (APP/PS1) mice at different stages of pathology relative to normal aging. Amyloid burden and microglial density were quantified with whole-brain light-sheet microscopy. CSF1R-mediated microglial depletion explored effects of microglia on sleep loss.

Results: Amyloid plaques caused non–rapid eye movement (NREM) sleep loss that did not worsen with increased plaque burden. Aging reduced REM sleep and eliminated sleep rebound. Amyloid pathology was associated with …

Agricultural Evidence Synthesis At A Critical Juncture: Quality Gaps And Implications For Evidence-Based Agriculture, Chao Cai, Jane Yatcilla, Justyna Czader, Sylvie Brouder, Jeffrey Volenec

Libraries Faculty and Staff Scholarship and Research

Systematic reviews and meta-analyses have become essential tools for synthesizing evidence to guide agricultural policy and practice, yet whether these syntheses are themselves conducted with sufficient rigor has rarely been systematically assessed. This study provides a field-wide assessment of reporting quality in agricultural evidence synthesis, examining whether existing reviews are conducted with sufficient transparency and rigor to support the policy and practice decisions they are meant to inform. We drew a random sample of 244 systematic reviews and meta-analyses from a bibliometric dataset of 1,709 articles published between 1997 and 2023, evaluating reporting quality using a 12-indicator rubric across four …

The Forensic Implications Of Hydrochloric Acid (Hcl) Exposure On Dna Preservation In Human Teeth, Shaelyn Lee Zimmerman

Graduate Student Theses, Dissertations, & Professional Papers

Identity is a human right, and forensic anthropological methods are often aimed at returning identity to decedents. Three main pathways are used for the identification of human remains: fingerprints, dental records, and DNA analysis. Identification efforts may be hindered when perpetrators attempt to obscure the victim’s identity. In cases where corrosive substances, such as hydrochloric acid (HCl) are used, dental comparison and fingerprinting often fail and genetic analysis becomes the best chance of achieving personal identification.

Previous studies have shown teeth are an excellent source of DNA. Large, multi-rooted teeth, such as molars, are often preferred because they contain the …

Reframing Sexual Assault And Intimate Partner Violence Through A Maternal And Child Health Lens: Implications For Integrated Prevention, Policy, And Practice, Daija C. Gibson

Theses and Dissertations

Sexual assault and intimate partner violence remain persistent public health concerns in the United States, with significant consequences for individual health, family stability, and population well-being. Although these forms of violence are frequently addressed through criminal justice and behavioral health frameworks, less attention has been given to their implications within maternal and child health, where relational dynamics, life course development, and intergenerational outcomes are central. This study reframed SA and IPV as core MCH issues to examine how integrated, systems-based approaches can strengthen prevention efforts. A structured literature review and systematic synthesis of peer-reviewed studies published between 2015 and 2026 …

Searching For Cause Of Unexplained Protein Interaction With Multiple Assembly Methods, Gavin Anderson

Master's Projects

Research into colistin adjuvants has identified interactions between a host of proteins and proteins found within certain strains of bacteria. BLAST, a widely adopted local sequence alignment tool, was used to create a database containing the genomes of relevant bacterial strains, which would then be used to query against the previously identified proteins. Many of these strains do not have publicly available assemblies, which makes database construction difficult. CATwalk, a new naïve fragment extender, is first described in this paper and used to extend fragments of interest. BLAST results first identified short fragments with sufficient similarity, which can then be …

Detection And Characterization Of Cancer Using Cfdna Fragmentomic Analysis, Guneet Bhogal

Master's Projects

Cell-free DNA (cfDNA) fragmentomics has emerged as a promising non-invasive approach for detecting and characterizing cancer by analyzing DNA fragmentation patterns. These fragment patterns are unique and can be used to distinguish between tumor and healthy DNA. This paper uses machine learning models to detect cancer by evaluating Shannon entropy of fragment lengths at the first coding exon 1 regions and correlating them to targeted cancer genes. This approach was applied to two datasets consisting of samples with prostate, breast, and lung cancers. Our results indicated that exon 1 fragmentation entropy captures biologically relevant differences in cancer-specific chromatin organization and …

Combining Crispr And Nanoasv To Uncover The Rare Bacterial Communities Of The Human Oral Microbiome, Gilma Ruth Sevilla Alvarez

Master's Projects

Studying the oral microbiome is vital because its health implications are not contained to the mouth. Cariogenic bacteria cause tooth demineralization and oral microbes that translocate to extra-oral organ systems are linked to conditions like Alzheimer’s disease, heart disease, diabetes, and cancer. Some of these pathogens belong to the most abundant phyla in the oral cavity: Bacillota, Pseudomonadota, Bacteroidota, Actinomycetota, Spirochaetota, and Fusobacteriota, which together comprise 94% of the oral microbiome. This project uses CRISPR-Cas9 to deplete sequences from highly abundant phyla and the Eubacteria domain, enriching the remaining 6% of rarer taxa. Paired with NanoASV for single-nucleotide resolution, this …

Bees Carry More Exposed Pollen Than Flies And On Body Regions Well Placed For Floral Contact, Robert Warren

Biology Faculty Datasets

Pollination studies generally emphasize bees, although flies are abundant flower visitors and may remain active under conditions in which bees do not forage. Pollination success depends not only on how much pollen is carried but also if the pollen is carried on body surfaces likely to contact flower stigmas. We compared exposed pollen load and its body placement on 527 bee (Hymenoptera) and fly (Diptera) specimens collected in a commercial apple orchard. Pollen was quantified by direct microscope counts for 376 specimens and hemocytometer wash counts for an additional 151 specimens. Pollen concentrated within scopae and corbiculae, which is less …

Synaptic Connectivity Of Rod Bipolar Cells In The Mouse Retina: A Connectomic Analysis Using Webknossos, Harold F. Eshun

Williams Honors College, Honors Research Projects

Rod bipolar cells (RBCs) are key interneurons in the mouse retina that transmit signals from rod photoreceptors to downstream amacrine and ganglion cells under scotopic (low-light) conditions. Although their general morphology and function are well established, the fine-scale organization of their synaptic inputs and outputs remains incompletely characterized. This project aims to map the pre- and postsynaptic partners of a fully reconstructed rod bipolar cell using the Yu volume, a serial block-face electron microscopy dataset from the ventral retina of an adult wild-type mouse. Using the webKnossos platform, I identify synaptic ribbons in the axon terminals of the rod bipolar …

Additionally, peptide Hv1a has promising effects as a more narrow-spectrum pesticide.

Pipeline Corrosion And Relevant Microbial Influence, Renee E. Bamberger

Williams Honors College, Honors Research Projects

This study investigated the role of microbial activity and oxygen availability in the corrosion of carbon steel pipelines with a focus on microbially influenced corrosion (MIC). Sediment collected from Old Woman Creek, Ohio, was used to simulate natural soil conditions, and carbon steel coupons were incubated under four treatments: nonsterile oxic, nonsterile anoxic, autoclaved oxic, and autoclaved anoxic over 85 days. Corrosion was assessed through mass loss measurements and the analysis of pH, sulfate, chloride, and dissolved iron concentrations. The greatest mass loss was observed in autoclaved oxic conditions, contrary to the initial hypothesis that microbial activity would greatly enhance …

Reconnecting The Body With Nature: Inspired By Advances In Biomimicry, Elyse M. Orosa

Williams Honors College, Honors Research Projects

Reconnecting the Body with Nature: Inspired by Advances in Biomimicry will visually address the symbiotic relationship between nature and humans. The drawing series is inspired by the growing design field of biomimicry and its technological and architectural innovations influenced by nature’s systems and physical adaptations. Just as nature is limited by human misuse, humans are physically and neurologically limited by the state of the environment, and with this, form and function of both nature and humans will be equally represented and explored throughout the body of work presented. Biomimicry can help solve environmental issues such as rising CO2 emissions and …

Effects Of Warmer Springs And Urbanization On The Nest Choice Of Temnothorax Ants, Keana Royce

Williams Honors College, Honors Research Projects

Climate change is altering winter and spring conditions in northeast Ohio, with urbanization and the urban heat island effect likely intensifying these changes. This preliminary study examined how Temnothorax ants alter nest-site preference in response to climate change and urbanization. I hypothesized that colonies exposed to warmed treatments would select hickory nuts to buffer against thermal/urban stressors. Identical in situ experimental setups were deployed at a rural site and an urban site and data collection occurred from late winter to early spring. Control colonies experienced ambient temperatures while experimental colonies were warmed +4°C above ambient temperatures. Colonies had the choice …

C. Difficile Detection Method For First Responder Glove Application, Alli N. Senedak

Williams Honors College, Honors Research Projects

Clostridioides Difficile (C. diff) is a Anaerobic Gram-positive bacillus that is capable of spore formation, making it difficult to control its spread and duration in clinical environments. This phenomenon can provide danger to first responders, healthcare workers, and patients. The goal of this project is to create a biosensor capable of detecting C. diff in a clinical setting that can be applied to a glove apparatus. The project will involve the use of C. diff aptamers activated on the surface of an electrode. Once surface activation has been verified via surface analysis, the electrodes will be exposed to C. diff …

Repurposing Cyclin-Dependent Kinase Inhibitors For The Discovery Of Novel Antiplasmodial Compounds, Ritam Bhowmik

Honors Undergraduate Theses

Malaria remains a major global health burden with over 282 million cases annually and rising resistance to artemisinin-based combination therapies. Plasmodium falciparum, the most lethal malaria parasite species in humans, relies on tightly regulated cell cycle progression during replication within red blood cells. Cyclin-dependent kinases (CDKs) are central regulators of eukaryotic cell division and transcription, and several CDK-like enzymes in P. falciparum, including Pfmrk and PfPK6, are essential for parasite growth and structurally distinct from human kinases. This study evaluated whether commercially available human CDK inhibitors (CDKIs) targeting cancer pathways could be repurposed as novel antimalarial compounds. A library of …

Manuka Honey Modulates Oxidative Stress In Neuro2-A Cells Through Mitochondrial Regulation, Rachel Abramovici

Honors Undergraduate Theses

Manuka honey is known for its vital usage in wound healing, being an agonist towards fighting infections, and is an acting antioxidant [32]. Its main constituents are flavonoids and phenolic compounds, with methyl syringate (MSYR) being a major active ingredient. The specific compounds responsible for these antioxidant effects, particularly in the CNS, remain unclear. It is hypothesized that pre-treatment of mouse neuroblastoma cells with MSYR followed by hydrogen peroxide exposure will activate the AMPK/SIRT1/PGC-1a pathway, due to MSYR’s phenolic structure, and thus reduce oxidative stress and improve mitochondrial biogenesis. Hydrogen peroxide is a standard reactive oxygen species (ROS) treatment to …

Multicomponent Deoxyribozyme Probes For Targeted Detection Of Cancer Associated Gene Insertions, Samuel R. Veleke

Honors Undergraduate Theses

Insertions and deletions (indels) in DNA sequences of genes are linked with cancers such as glioblastoma (GB). Thus, indels may be used as potential cancer biomarkers. In the NANOG gene, its pseudogene NANOGP8 has a 22 base pair insertion sequence for GB patients. In this work, the NANOG gene and the insertion sequence were detected in one sample using a dual-fluorescent assay containing two multicomponent split deoxyribozyme (Dz) probe complexes. One complex used TXR fluorescence to detect the gene regardless of the insertion’s presence. The other complex used fluorescein (FAM) fluorophore to detect the insertion. The probes were able to …

Evaluation Of Tactile Cueing Embedded In An Aviation Headset On Pilot Altitude Control, Nicholas D. Wilson, Jessica Van Bree, Matthew Cleveland, Sunny Charakuru, Thomas Petros, Richard Ferraro, Kouhyar Tavakolian

Journal of Aviation/Aerospace Education & Research

This study evaluated the effectiveness of tactile cueing integrated into a pilot’s headset on pilot altitude control during simulated instrument conditions. Pilots typically rely on visual and auditory inputs to maintain situational awareness, but in high-workload or instrument meteorological conditions (IMC), these channels can become overloaded. One underutilized alternative for alerting is a tactile cueing apparatus. Using an X-Plane simulation of a Piper Archer equipped with a G-1000 avionics suite, 39 FAA-certified pilots flew two precision approaches. The experimental group (n = 20) received haptic cues via ear seal-embedded tactors when deviating from assigned altitude or glideslope. The control group …

Investigating The Interaction Of Gram-Positive Lactobacillus Species With Mucin In The Context Of Barrett's Esophagus, Ritisha Suresh

Honors Undergraduate Theses

Gastroesophageal Reflux Disease (GERD) can progress to the precancerous Barrett’s Esophagus (BE) condition, in which the normal esophageal squamous epithelium is replaced with a columnar epithelium containing goblet cells. Mucins, sticky substances, are secreted in response to bile acid exposure during reflux episodes to protect the esophageal epithelium. Goblet cells secrete these mucins, which can also scaffold microbial colonization. Probiotic Lactobacillus bacteria can use glycosidase enzymes to process mucin and metabolize them into their component sugars (glycans). This project aims to identify the role of the Lactobacillus-mucin interaction in BE, as glycan availability could confer an advantage to Lactobacillus …

Activity-Dependent Remodeling Of Muscle Architecture During Distinct Locomotor Behaviors In Caenorhabditis Elegans, Adina Fazyl, Akash Anbu, Sabrina Kollbaum, Andres G. Vidal-Gadea

Faculty Publications – Biological Sciences

Muscle structure is dynamically shaped by mechanical use, yet how distinct locomotor behaviors influence sarcomere organization remains poorly understood. In Caenorhabditis elegans, crawling and swimming constitute discrete gaits that differ in curvature, frequency, and mechanical load, providing a tractable model for studying activity-dependent remodeling. Using confocal imaging of phalloidin-stained body-wall myocytes, we quantified myocyte geometry, sarcomere length, and sarcomere number across anterior, mid-body, and posterior regions in animals reared exclusively under crawling or swimming conditions. Quantification and hypothesis testing used linear mixed models that accounted for repeated myocyte measurements within animals, with interaction terms testing region-specific effects of locomotor …

To Flea Or Not To Flea: Abiotic And Biotic Factors Driving Flea Parasitism On Wild Deer Mice, Parker Todd, Angela Luis, Mike Kinsella

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Deer mice (Peromyscus maniculatus) are an abundant North American rodent and the primary reservoir for Sin Nombre virus (SNV), a hantavirus with a 30-40% case fatality rate in humans. While ectoparasites, such as fleas, are not considered vectors of SNV, their bites may indirectly affect the transmission of SNV by impacting host condition or immune function. These impacts could potentially lead to an increase in host susceptibility and/or an increase in viral shedding, yet there is still little knowledge on what influences flea parasitism on deer mice in western Montana. This study looks to examine how mouse sex, …

The Sub-Lethal Effects Of Trematode Parasites On The Migratory Behavior Of Lesser Scaup (Aythya Affinis), Scott Alan Herman

Graduate Research Theses & Dissertations

The introduction of the invasive freshwater faucet snail (Bithynia tentaculata) and its associated parasites in the Upper Mississippi River and Great Lakes Region provides the opportunity to investigate how anthropogenic stressors impact the life history of lesser scaup (Aythya affinis) using the Mississippi Flyway. To understand the life histories and interactions between lesser scaup and faucet snails we examined historical records, research, and ecology textbooks. Our literature review identified critical knowledge gaps in lesser scaup literature surrounding population dynamics, reproduction, and migration. Specifically, the sub-lethal effects of invasive trematodes on the migratory behavior of lesser scaup in the Upper Mississippi …
