Glioblastoma Multiforme: A Pathologic Breakdown Of One Of Neuro-Oncology's Greatest Challenges, Rosemary Westphal, Ms

Student Papers, Posters & Projects

Glioblastoma multiforme is the most common adult primary tumor with a grim median survival time of 14.6 months. It is characterized by rapid progression, diffuse infiltration, and rather poor clinical outcomes. The WHO classifies GBM as a grade 4 diffuse astrocytic tumor with distinctive histopathological features including high mitotic activity, marked cellular atypia, microvascular proliferation, and necrosis. Advances in molecular diagnostics have further classified GMB into IDH-wild type and IDH-mutant subtypes, with important therapeutic and prognostic implications. Key genetic alterations, such as EGFR amplification, PTEN loss, TP53 mutations, TERT promoter mutations, and MGMT methylations, have been identified as contributing to …

Predicting Ventilation From Single Breathing Phase Non-Contrast Ct Using Swin Transformers, Yi-Kuan Liu, Hsu-Ting Kuo, Alaa Melek, Richard Castillo, Yevgeniy Vinogradskiy, Lili Zhao, Girish Nair, Edward Castillo

Department of Radiation Oncology Faculty Papers

BACKGROUND: Pulmonary ventilation imaging enables functional avoidance radiotherapy treatment plans by quantifying regional lung function. However, current clinical standards, such as 99𝑚Tc-based single-photon emission computed tomography (SPECT), rely on radioactive tracers, which can introduce imaging deposition artifacts. CT ventilation imaging (CTVI) methods based on both physical models and deep learning approaches currently require multiple CT images as input, such as the inhale/exhale phases of a 4DCT. While the theoretical foundation of physics-based CTVI is built on multi-phase information, the feasibility of single-phase deep learning CTV models has not been determined.

PURPOSE: While deep learning methods have predicted SPECT ventilation from …

Computed Tomography For Four-Dimensional Dose Calculation: Effect Of Detector Array Length, Inhwan Yeo, Qianyi Xu

Department of Radiation Oncology Faculty Papers

PURPOSE: Four-dimensional computed tomography (4DCT) is susceptible to a geometrical error when respiration changes upon patient shift. 4DCT using 16-cm detector arrays, not needing the shift, has been shown to improve geometrical accuracy, compared with a conventional 4DCT (4-cm array), albeit with some Hounsfield unit discrepancies. The 4DCTs were validated for 4D planning.

MATERIALS AND METHODS: A lung-mimicking phantom containing a spherical target with ten respiratory traces and three tumor-shaped targets with their traces was respectively imaged when, to each of the ten-positions/phases, the lung was moved (1) step-wisely by helical scan at each movement (ground truth; 4DCT_GT), …

Effects Of Kiwifruit Extract On Apoptosis And Cytokine Production In Inflamed Thp-1-Derived Macrophages, Adrian Cruz, Isbella Brigman

Posters - 2026

White blood cells are essential components of the immune system involved in helping defend the body against infections. Macrophages are a type of white blood cell that play a major role in stimulating and regulating the inflammatory response. Inflammation is a natural response of the immune system to infection, injury, or harmful stimuli. Scientific research commonly studies inflammation by exposing immune cells to lipopolysaccharide (LPS). Macrophages stimulated with LPS undergo changes in cell processes such as apoptosis which is programmed cell death. Apoptosis is crucial for the immune system that helps eliminate infected or damaged cells to prevent the spread …

The CIM framework integrates Critical Race Theory, Intersectionality, and Culturally Responsive Pedagogy to reframe mentoring as a social justice practice grounded in equity, empowerment, and relational trust. Using qualitative content analysis of pláticas, the study uncovers three key …

Who's Qualified? Examining Attorney Perspectives On Lpcs In The Legal System, Becca Wilson, Bernave Vega

Posters - 2026

Legal cases frequently intersect with mental health concerns, positioning Licensed Professional Counselors (LPCs) to contribute clinical expertise in custody disputes, trauma documentation, and psychological functioning. As mental health issues become increasingly central to both civil and criminal proceedings, the working relationship between attorneys and counselors carries real consequences for clients, yet LPCs entering legal settings often face challenges related to role clarity, courtroom preparation, and professional credibility. Existing research has focused primarily on counselors' forensic experiences, leaving attorney perspectives on LPC involvement largely unexplored. This gap is meaningful, as attorneys serve as gatekeepers to expert involvement and their perceptions of …

• This research investigated how daily stress levels influence the intensity of dreams. The study aimed to clarify the relationship between stress and dream intensity, enhancing understanding of stress’s broader effects on mental health. • Building on Rush’s concept of a “goldilocks zone” in the stress scale, where moderate stress benefits well-being while too little or too much stress can cause harm (2024). The current study used the hallucination model of dreaming from Gillespie and Trakas (2024), which views dreams as vivid, perception-like experiences that can amplify emotions. Drawing on Gessert’s methods for measuring stress and nightmare frequency, stress is …

Impact Of Liver-Secreted Small Extracellular Vesicles On Myotube Funcation, Tatiana Barrantes, Ioannis Tsialtas, Qing Zhang, Kevin Koronowski

Posters - 2026

Extracellular vesicles (EVs) mediate intercellular communication by transferring molecular signals between tissues. Liver-derived EVs contribute to metabolic regulation and have been implicated in tissue cross-talk during health and disease. Skeletal muscle is a highly metabolic tissue that depends on mitochondrial respiration for energy production. However, whether liver-secreted EVs influence myotube mitochondrial function remains unclear. Here, we investigate the impact of liver-derived EVs on myotube mitochondrial respiration.

America First: U.S Justification For Intervention In Latin America, Lenardo Buentello

Posters - 2026

In November 2025, the United States released a new National Security Strategy that strongly focuses on securing key resources before rival countries, especially in the Western Hemisphere. This approach is like policies like the Monroe Doctrine, which emphasized U.S. influence in the region. This strategy is already being put into action in Venezuela, where U.S. forces captured President Nicolás Maduro and his wife on drug trafficking charges. These actions reflect the strategy’s focus on national security and resource control. Many countries question whether the U.S. acted legally and argue that it ignored international norms. Latin America has become a region …

The Effects Of Sour & Spicy Food On Visual & Auditory Reflexes, Aditi Kumar, Alondra-Sophia Martinez, Magdalena E. Saad, Emma J. Welsch

Posters - 2026

• The reflex reaction time measures how quickly the nervous system can respond to a stimulus. • In the experiment, both visual and auditory reflexes were measured to evaluate differences in reaction time after the consumption of sour and spicy foods. • Spices and herbs produce different signals that interact with the nervous system. (McMullen 2024) • Comparing the response times from before and after consumption, this experiment allowed us to determine if different tastes affect reflex reaction times.

Evaluation Of An Affordable Prosthetic Liner In Resource Limited Settings, Samerial Brown

Posters - 2026

The lower limb prosthesis is an important assistive technology for persons with limb amputations and differences. The interface (prosthetic liner) between the rigid prosthetic socket and the residual limb is often made of silicone, urethane or thermoplastic elastomer gel. This material provides cushioning and support as well as suspension for the transtibial (below knee) prosthetic leg. Unfortunately the cost of liners range from $3-$600. This cost precludes its use in resource limited settings such as Sri Lanka. As a result patients are fit with a foam liner which has less cushioning and suspension capabilities than a gel type liner. This …

Does The Placenta Predict Depression During Pregnancy? Investigating Hormonal Links In High-Risk Pregnancies, Sonia Cerrillo, Hanne Hoffmann Phd

Posters - 2026

• Perinatal depression is a common disorder that affects maternal and infant well-being.

• Serotonin is an important mood-regulating neurotransmitter, and reduced serotonin signaling has been linked to depressive symptoms.

• Tryptophan (TRP) is the precursor for serotonin, where most TRP is metabolized through the kynurenine pathway.

• TPH supports serotonin synthesis, while IDO and TDO drive kynurenine production.

• During pregnancy, inflammation and stress may shift TRP away from serotonin, creating a placental “tryptophan steal.”

• We examined whether placental DNA methylation of these genes differs in high-risk pregnancies.

• We hypothesized that placental DNA methylation of genes in …

Existing research suggests that telehealth occupational therapy can produce similar outcomes to in-person care in certain populations; however, variability in patient characteristics, technological readiness, intervention demands, and environmental contexts influences its suitability, and limited research examines how practitioners determine the appropriate service delivery model. The purpose of this qualitative study is to explore the factors that influence occupational therapy practitioners within a Veterans Affairs healthcare setting in South Carolina when determining the appropriateness of telehealth, in-person, or hybrid service delivery …

Visual And Tactile Motion Cues Enhance The Categorisation Of Novel Object Shapes, Martina A. Seveso, Rebecca J. Hirst, Alan O’Dowd, Ivan Camponogara, Fiona N. Newell

All Works

Object categorisation is a fundamental cognitive process, involving the integration of information across the senses. We investigated, using smartphones, whether visual and tactile motion cues could enhance object category learning and generalisation to novel object shapes. Two categories of similar shapes were associated with specific correlated visual and tactile vibration motion cues. After learning object categories, participants were assessed on categorisation of learned and novel objects across four cue conditions: shape-only, shape-visual motion, shape-tactile motion, and shape-visual and tactile motion. We also assessed if accuracy was influenced by blocked versus interleaved cue-conditions at test. In Experiment 1, we found more …
