Bound By Brotherhood: Social Networks Predict Job Satisfaction And Trust Among Frefighters, Ashley Frost

Posters - 2026

The primary purpose of this study was to better understand the correlation between the social support networks among firefighters, also known as “brotherhood”, and their job satisfaction. The secondary goal was to explore potential indicators of what traditions entailed within the fire department and their significance in fostering brotherhood. Former research has articulated the bonds within the fire service and how team comradery and job satisfaction influence brotherhood, however; limited research has investigated how traditions within the fire service influence brotherhood. It was expected that brotherhood would have a positive correlation with job satisfaction (H1), that there would be a …

The Relationship Between Environmental Cues And Emotional Responses, Isbella Cantrell, Ashley Frost, Mark Sanchez

Posters - 2026

The purpose of this study was to better understand if the environment influenced an individual’s emotions by observing horror and non-horror video games and coding the frequency of observed reactions. Former research illustrates that emotional arousal during video games may activate defensive behaviors similar to real-life threats. Three different YouTube streamers were observed playing one horror and two non-horror video games. All three streamers played the same three games. It was expected that all three players would have more frequent reactions to horror games as opposed to non-horror games (H1), that anger reactions would occur more frequently than sympathetic reactions …

Visible And Invisible Empires: The Revival Of The Ku Klux Klan 100 Years Ago, Christian Molina

Posters - 2026

Hatred and violence breed division, and that division breeds more hatred and violence. 1920s American politics was characterized by name-calling, finger-pointing, scapegoating, whataboutisms, and violence. The nation entered a self-perpetuating cycle. Groups keen for growth, power, and profit captured the angry, stressed, and less-informed with lies and misleading numbers. In particular, the Ku Klux Klan captured nearly 4 million Americans, roughly 1 in 12 men at the time. But the Klan, large as it was on a local level, was led and masked by a handful of national leaders. The Klan was not just bands of rogue vigilantes cruising the …

Posters - 2026

Since its founding in 1852, St. Mary’s University has evolved from a small institution into a diverse and inclusive community that has worked to overcome discriminatory barriers. Originally founded to serve Mexican students in underserved communities, the university has reflected San Antonio’s Cultural diversity since its earliest years. Its founder, Reverend John Marie Odin, envisioned supporting a “melting pot” of cultures within the city (Flores, 2019). While the university has grown significantly in enrollment, Hispanic culture and traditions have remained a central part of its identity. Today, with over two thousand students enrolled, St. Mary’s University continues to not only …

Effects Of Tubulin-Binding Medications On Microplastic Uptake And Cyotoskeletal Functionality Across Diverse Cell Types, Alejandra D. Favela Santos

Posters - 2026

• Microtubules are composed of of a- and b- tubulin heterodimers, vital for cell structure, shape, and intracellular transport • Microtubules are also useful as they separate chromosomes during cell division • Microplastics (< 5 mm) are considered a health threat and have been found throughout the whole body (1) o In several studies, microplastics have been correlated to higher rates cardiorespiratory issues, endocrine disruption, and cancer (1) • Tubulin-binding medications are widely used as chemotherapeutic agents as they are known for disrupting cell division and targeting tubulin (2,3) o In this study, these medications were used to determine whether microtubules play a role in microplastic uptake § Colchicine typically binds to tubulins and arrests polymerization and growth § Nocodazole disrupts polymerization and prevents spindle formation § Vinblastine inhibits microtubule assembly and disruptions miotic spindle formation.

• The purpose of this study was to determine if different concentrations of tubulin-binding medications affect microplastic uptake o C2C12, RAW 264.7, and MOVAS cell lines were used to evaluate whether these changes are cell type specific 

If microtubule dynamics are disrupted, microplastic uptake can be affect in a concentration-dependent and cell type- specific manner.

Development Of A Dendritic Cell Model To Unravel The Secrets Of Cards Toxin, Lizbeth Gomez

Posters - 2026

Dendritic cells (DCs) are derived from hematopoietic stem cells of the bone marrow. They are the most efficient antigen presenting cell, presenting antigens to T cells to initiate clonal expansion and differentiation of the T cells into memory and effector cells. Thus, activating the effector functions of T cells in cell-mediated and humoral immune responses (2). Community-acquired respiratory distress syndrome (CARDS) toxin is produced by Mycoplasma pneumoniae that causes acute and chronic lung infections (4). Dendritic cells play a key role in the immune response to respiratory mycoplasmas (3). However, the mechanism underlying in DC and CARDS toxin interactions are …

Signaling Response Of Epinephrine Treated Cards Toxin-Infected Thp-1 Macrophages, Trinity Martinez

Posters - 2026

Aspiration pneumonia is a common mild case of pneumonia, a disease where the lungs are inflamed and filled with fluid, compromising respiration and gas exchange. One common cause of mild pneumonia is bacterial infection via a pathogen known as Mycoplasma pneumoniae. M. pneumoniae causes a variety of respiratory illness- ranging from pharyngitis, tracheobronchitis, mild pneumonia- and in rare cases encephalitis. M. pneumoniae produces the CARDS toxin, which participates in ADP-ribosylation and vacuolization (Kannan et al., 2006)1. The CARDS toxin causes aspiration pneumonia by paralyzing the cilia that lines the respiratory tract. Epinephrine, or Adrenaline- is a hormone that is medically …

G-Quadruplex Dna-Driven Genomic Instability Under Ber Loss, Addison Belick, Claryssa Gutierrez, Joslynn Rosas, Andrea Vargas

Posters - 2026

Base Excision Repair (BER) is a cellular tool that can repair damaged DNA (Hindi et al., 2022, Cellular and Molecular Life Sciences). G-quadruplexes (G4s) are unique 4-stranded structures in DNA or RNA that are rich in guanine (Gray et al., 2023, Nat. Chem. Biol). The purpose of this study is to understand whether BER contributes to the removal of G4s in DNA. This will determine if the BER-deficient yeast is more sensitive to treatment with G4-binding drugs than the BER-proficient yeast. We will replace the APN1 gene in the yeast genome with the URA3 gene, because the wild type yeast …

Healthcare Systems & Policy Implications For Tele-Dentistry Policies On Access To Dental Care For Underserved Populations In The United States, Deeya Bhadresa

Posters - 2026

Access to dental care remains a significant public health challenge for people in rural and low-income communities. Tele dentistry has shown the ability to expand preventive services, improve care coordination, and reduce geographic barriers. However, inconsistent Medicaid coverage, limited infrastructure, and low provider participation restrict its impact. The main recommendation is standardizing Medicaid tele dentistry coverage and reimbursement across states to improve access and equity. Action is needed now to preserve post–COVID-19 telehealth gains and address persistent oral health disparities.

Evaluating The Effects Of Akt Knockdown And Everolimus Treatment On Ewing Sarcoma, Arisha Arif, Alfie Barcenez, Nicole Vanegas-Riddick

Posters - 2026

The purpose of this study is to use the gene AKT1, due to the interest in AKT1’s role in cancer cell proliferation, and the drug Everolimus, to determine if combined targeted therapy works as a more efficient therapeutic approach. We hypothesize that the knockdown of AKT1 will increase the sensitivity of Ewing sarcoma cells to Everolimus, resulting in reduced proliferation and/or survival compared to drug treatment alone. This would suggest that AKT1 normally protects cells from drug-induced stress. Ewing Sarcoma has been connected to chromosomal translocations and most common in pediatric patients. It is most often treated with chemotherapy and …

Inflammation is a critical biological response that enables the immune system to react to infections, injuries, or stressful situations. However, chronic or excessive inflammation can lead to tissue damage and contribute to a wide range of diseases, including neurodegenerative disorders, metabolic syndromes, and immune dysregulation. 3,4 Interleukin-1 beta (IL-1β) is a key pro-inflammatory cytokine that plays a central role in initiating and amplifying the immune response. 1,2 It is primarily produced by activated monocytes and macrophages in response to stimuli such as pathogens or stress signals. In addition, IL-1β acts on the hypothalamus to induce fever, which creates an environment …

Sirna Knockdown Of Rptor Alters Gene Expression In Ewing Sarcoma Cells, Sergio Cipriano, David Leavitt, Michael Oliva, Liam Valdez

Posters - 2026

Ewing sarcoma is a highly aggressive cancer that primarily affects children and young adults. Although treatment options exist, many patients do not respond effectively, showing the need for improved targeted therapies¹. RPTOR is a key in mTORC1 complex which regulates cell growth, proliferation, and survival². LY2874455 is a selective pan-FGFR inhibitor that targets growth factor signaling pathways involved in tumor progression³, and FGFR signaling interacts with pathways such as mTOR, making it a potential target for combination therapies. We hypothesized that silencing RPTOR in Ewing sarcoma cells would disrupt mTOR signaling and alter expression of genes linked to cell survival …

Libertatis Cunabula: Slavery In San Antonio, Makayla Hernandez

Posters - 2026

This research on the taxes collected by our city and county exposes the pervasiveness of slavery in San Antonio. This truth is shockingly new for San Antonio. No marker nor plaque nor historical commemoration exists to honor the memory and contributions of enslaved San Antonians, nor to force a reckoning with the legacy of prominent enslavers among San Antonio’s leading families and Alamo heroes. This research project recovers every person listed as enslaved in the Bexar County Tax Assessment Records from 1837 to 1862 and names their enslavers. It immediately counters the assumption and assertion that slavery was insignificant in …

Ultragps: A Low-Cost, Open-Source Ultrasonic Positioning System, Scott Roelker Murillo, Nnamdi Jesse Onwuzurike

Posters - 2026

We want to raise the bar in high school robotics. In Texas, and likely in many other states as well, high school robotics has reached a roadblock when it comes to autonomous navigation. In many competitions, the autonomous portion sees few, teams successfully completing tasks that require positioning and guidance. In modern robotics, it is no longer sufficient for a robot merely be “remote controlled.” They need to be able to navigate independently and adapt to the environment around them. To achieve this goal a positioning system is needed to develop the foundational algorithms for autonomous controls. However, these systems …

The Invisible Filipina Migrant Worker In Saudi Arabia: Analyzing The Perpetuation Of Colonial Power Dynamics Through The Feminization Of Migrant Care Labor, Allyson Collado

Posters - 2026

Every year, over a million Filipino women move overseas as domestic migrant workers, sending remittances that sustain almost a tenth of the Philippine economy. The Philippine government glorifies these Overseas Filipino Workers (OFWs) as heroesm, but they are still under-protected and treated as invisible, replaceable commodities in nations like Saudi Arabia.

This paper argues that the exploitation of Filipina migrant care workers is not just a side effect of neoliberal globalization, but a perpetuation of colonial power relations that is built into Philippine labor export policy and Saudi Arabia's legal architecture.

Take A Hit? Take A Hit: Quantifying Cell Death In E-Cigarette Exposed Bronchial Epithelial Cells Following Cards Toxin Treatment, Truman Havrda, Hannah Jiron, Sierra Trevino

Posters - 2026

The rapid rise of e-cigarette use among young adults has created a significant public health challenge, as the popularity of "vaping" has grown faster than our understanding of its long term cellular consequences. Current research indicates that e-cigarette vapor (ECV) induce high levels of oxidative stress and impair the lungs' ability to clear bacterial pathogens. Furthermore, ECV exposure upregulates specific receptors on the surface of airway cells, essentially making it easier for bacteria to adhere to and infect the lungs. While we know that both e-liquids and vapor trigger inflammatory responses and cytotoxicity, there is limited data on how these …

Code switching is the combination of two or more languages spoken due to the proximity of communities (Zentella, 1997). Code switching is very common in areas with a majority Hispanic community (Devan et al., 2024). Although Spanglish is highly controversial, it is widely used through multiple parts of Texas (Stavans, 2008) Spanish in San Antonio is very different than Mexico Spanish according to Mexican-Americans (Gillespie-Duelos, 1975)

A Research Proposal: Gender Differences In The Experience And Impact Of Fear Of Missing Out (Fomo), Valeria Garcia, Yesenia De Leon

Posters - 2026

Fear of Missing Out (FoMO) is the anxiety individuals feel when they believe others are having rewarding experiences without them, a feeling that has increased with the rise of social media. Constant exposure to others' curated lives can lead to social comparison, increased social media use, and negative outcomes such as decreased academic focus and poorer mental health. Research suggests that FoMO may be experienced differently across genders due to differences in social expectations and online behaviors. For example, women may be more likely to engage in social comparison and seek validation, while men may use social media for different …

Property Taxes And Educational Inequality: How Funding Structures Perpetuate Social Class Divides In San Antonio, Texas, Kristanna Martinez, Camila Ore

Posters - 2026

The U.S education system relies heavily on property taxes, creating an unhealthy dependence where property value dictates the quality of education depending on the school district

• In the historical case Edgewood v. Kriby, the Texas Supreme Court ruled that the reliance on local property taxes for school funding was unconstitutional, as it violated the state requirement that all children receive a “thorough and efficient” education. The court ruled that every district must be provided the same ability to obtain educational funds regardless of their local property wealth. • The purpose of this study is to examine if the 2025-2026 …

Between Boots And Beaches: A Study Of Spanglish Across The Souothwest, Payton Mayfield, Kaylynn Perez, Demetri Zoutis, Sandra Villarreal

Posters - 2026

When two living organisms reproduce, they create new life—an entity that is distinct, yet traceable to its origins through inherited traits. While languages are not biological, a similar process of creation can occur through contact and convergence. When two languages interact, a new vernacular may emerge, shaped by its linguistic “parentage” while developing its own structures, meanings, and cultural significance. Spanglish represents one such linguistic evolution. This study examines the development of Spanglish across the United States mid-West, with a focus on communities spanning from Texas to California. By comparing these regions, the research identifies both shared patterns and regional …

Healthcare Systems & Policy Implications For The Impact Of State Medicaid Reimbursement Rates On Access To Primary Care Services In Rural Communities: Turning Knowledge Into Action, Miriam Martinez

Posters - 2026

• Where a child lives can determine whether they receive care or go without it. • Access to primary care is essential for prevention, early diagnosis, and treatment, but rural areas face persistent challenges such as provider shortages and geographic isolation. • Medicaid serves as the primary source of health coverage for low-income children; however, reimbursement rates vary by state and are often lower than other forms of insurance. • This study examines how Medicaid reimbursement policy contributes to disparities in access to care for rural children and reflects broader structural inequalities within the healthcare system.
