Beyond Stabilization: Biological Healing, Structural Exclusion, And The Recovery Gap After Border-Fall Trauma At The U.S.-Mexico Border, Julia Robinson May 2026

Beyond Stabilization: Biological Healing, Structural Exclusion, And The Recovery Gap After Border-Fall Trauma At The U.S.-Mexico Border, Julia Robinson

Undergraduate Honors Theses

This honors thesis examines the biochemical, ethical, and public health consequences of insufficient post-operative follow-up care for undocumented immigrants injured in border falls. Discussing pathways of inflammation resolution, wound healing, and bone remodeling, this thesis argues that recovery depends on tightly regulated molecular and cellular processes that are highly vulnerable to disruption without continued monitoring and rehabilitation (Loi et al., 2016; Maruyama et al., 2020). When follow-up care is absent, these processes can be predicted to derail, leading to infection, impaired healing, and permanent disability (Chung & Sohn, 2025; Howard et al., 2020; Kruidenier et al., 2018). Framed through principles …

Introduction: Cocaine use disorder (CUD) is a significant public health concern in the USA, with considerable prevalence and mortality and no Food and Drug Administration (FDA)-approved pharmacotherapies. Recent advances in addiction science emphasise the need for novel, mechanism-based treatments. Glucagon-like peptide-1 receptor agonists, such as semaglutide, have shown promise in modulating reward-related behaviours and may offer therapeutic benefits for CUD. We present a study protocol evaluating semaglutide, as an adjunct to cognitive behavioural therapy (CBT), as a novel approach for treating CUD.

Methods and analysis: This is a randomised, double-blind, placebo-controlled trial enrolling 75 treatment-seeking adults with CUD. Participants will …

Background: Bipolar Disorder (BD) is a severe mental illness, often emerging during adolescence, that is associated with significant psychosocial impairment. BD risk is elevated in offspring of affected parents, particularly those with antecedent symptoms (e.g., mood lability, subthreshold manic symptoms). However, robust, replicable brain-based markers of risk in this population are lacking. We assessed the degree to which the Regional Vulnerability Index for BD (RVI-BD), quantified as an individual's brain-wide similarity to BD patterns derived from meta-analytic studies, is elevated in youth at familial risk and correlates with symptom predictors of BD.

Methods: We recruited n=82 adolescents (10-15 years old), …

Cisplatin (DDP)-based chemotherapy serves as a foundational cornerstone in the clinical management of esophageal squamous cell carcinoma (ESCC). However, intrinsic or acquired resistance to DDP persists as a significant clinical challenge, severely undermining therapeutic efficacy and contributing to unfavorable patient prognoses. Through functional screening with a CRISPR/Cas9 knockout library, transcriptomic profiling of cisplatin-resistant cell lines and clinical specimens, and in vitro/in vivo validation assays, we identified PHKG2 as a key mediator of cisplatin resistance in ESCC. Mechanistically, PHKG2-mediated cisplatin resistance is driven by the phosphorylation of IGF2BP3 at residues T225 and T306. This post-translational modification enhances IGF2BP3 phase separation, thereby …

Local dendritic computations are thought to critically influence neuronal signaling and plasticity yet remain largely unexplored in vivo due to challenges in stably imaging small structures at ultrafast timescales. We developed a 3D real-time motion correction platform for movement-stabilized, ultrafast two-photon voltage imaging. By co-labeling CA1 pyramidal neurons with voltage and calcium indicators, we simultaneously measured somato-dendritic and electro-calcium coupling at multiple dendritic sites. We characterized isolated dendritic spikes and distance-dependent backpropagation of naturally occurring and photostimulation-evoked bursts and single spikes. We found that bursts backpropagated more reliably than single spikes, validated that somato-dendritic coupling decreases with distance from soma, …

Over the past 500 years, the convergence of three distinct paths - vaginal surgery, laparoscopy, and robotic technologies - has enabled the development of robot-assisted vaginal natural orifice transluminal endoscopic surgery (RA-vNOTES). The ongoing evolution of vaginal surgery has led to contemporary procedures such as hysterectomy, myomectomy, sacrocolpopexy, adnexal interventions, and oncologic operations, applicable to a wide range of diagnoses and pathologies. This approach offers patients significant benefits, including superior cosmetic outcomes, less pain, lower infection rates, and faster recovery of baseline quality of life. Surgeons benefit from improved ergonomics, better visualization, the ability to use multiple instruments, and enhanced …

Empowering Women: Understanding Neurological Changes In The Aging Brain, Joy Mckenzie May 2026

Empowering Women: Understanding Neurological Changes In The Aging Brain, Joy Mckenzie

InnovateHER Meeting 2026

Women tend to have more neurological changes than men as they age starting in their mid-30s (Mosconi, 2024). While aging is a natural process, the neurological changes can impact a woman’s personal and professional quality of life (Faubion et al., 2023; Gravini, 2023). For years, women’s neurological symptoms have been ignored by being told that their experiences are normal and just a part of life (Haver, 2025). That narrative is starting to shift with the increased awareness of changes specific to women. There are resources to assess cognitive changes such as memory, processing speed, and word finding and strategies to …

Faculty, Staff and Students Publications

Background: Human papillomavirus (HPV) is a sexually transmitted virus that causes various oropharyngeal and anogenital cancers. The HPV vaccine provides protection against several strains of HPV and is a key preventative tool against HPV-related cancers; however, vaccination rates remain suboptimal in the United States due to variable state mandates and misperceptions of vaccine efficacy and risks. As social media becomes an increasingly popular avenue for health discussions, platforms such as Reddit offer opportunities to understand public vaccine discourse, particularly among underrepresented groups. Furthermore, vaccine hesitancy and mistrust generally increased during the COVID-19 pandemic, potentially impacting HPV vaccination rates.

Objective: This …

Background: Aortic valve calcification (AVC) is the primary process leading to aortic stenosis. We examined whether polygenic risk scores (PRS) are associated with AVC beyond traditional atherosclerotic cardiovascular disease risk factors.

Methods: We included 6812 participants in MESA (Multi-Ethnic Study of Atherosclerosis) with computed tomography-measured AVC at Visit 1. Using previously published PRS we calculated weighted PRS, standardized within each ancestry group. The cross-sectional association per 1 SD higher PRS with AVC >0 was examined using multivariable logistic regression modeling with Bonferroni correction. The mean age was 62 years old, 53% were female, and 913 (13.4%) had AVC >0 at …

In vivo microscopy (IVM) has shown great promise to improve early detection of epithelial precancer, but it suffers from fundamental trade-offs that limit the resolution, field-of-view (FOV) and depth-of-field (DOF). Here, we present PrecisionView, a compact, deep learning-enabled endomicroscope that breaks these constraints and achieves 20 mm2 FOV and 500 µm DOF with 4 µm resolution, representing approximately 5× increase in FOV and 8× larger DOF compared to conventional IVM with similar resolution. PrecisionView integrates a deep learning-optimized phase mask and real-time reconstruction, enabling rapid in vivo assessment of two key hallmarks of cancer: epithelial cell nuclear morphology and subsurface …

School of Medicine Publications

Localized chemotherapy offers a promising strategy to improve therapeutic efficacy while minimizing the systemic toxicity of conventional cancer treatment, particularly following tumor resection. Electrospun nanofibers are well suited for this purpose due to their high porosity, extracellular matrix-mimicking architecture, and capacity for localized drug release. In this study, electrospun nanofibers based on PCL and PLGA were developed for localized cancer therapy. Three distinct nanofibrous architectures were fabricated: PCL nanofibers, PCL−PLGA blended nanofibers, and PCL−PLGA multilayered (tetra-layered) nanofibers, and their encapsulation efficiency was determined by high-performance liquid chromatography (HPLC). Scanning electron microscopy confirmed uniform, bead-free nanofibrous morphologies, while Fourier transform infrared …

Patients were excluded if they required prolonged inpatient care, had a history of organ transplantation, chronic pain or narcotic use, congenital or chromosomal disorders, inability to take acetaminophen or ibuprofen, and other significant medical diagnoses that could potentially alter postoperative pain management. All patients were prescribed a standard amount of oxycodone to be used for breakthrough pain in addition to ibuprofen and …


Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez May 2026

Rhythms Of Hippocampal Function And Memory After Moderate Prenatal Alcohol Exposure, Lilliana May Sanchez

Psychology ETDs

Fetal Alcohol Spectrum Disorders involve morphologic and neurobiological abnormalities in offspring subjected to prenatal alcohol exposure. Although not as well studied as high exposure, moderate prenatal alcohol exposure represents the most common and undetected form in humans. While learning and memory deficits have been well characterized at the behavioral level in humans with Fetal Alcohol Spectrum Disorders and in animal models of moderate prenatal alcohol exposure, few studies have determined the circuit or systems level mechanisms of the behavioral deficits. A complete understanding of the neural bases of memory deficits after moderate prenatal alcohol exposure is needed to ultimately identify …

Brain-Based Mechanisms Of Behavioral Impairment In Fetal Alcohol Spectrum Disorder (Fasd): The Neuroimaging Biomarkers Of Inhibitory Control, Zinia Pervin

Biomedical Engineering ETDs

The developing brain is highly susceptible to alcohol-induced toxicity, often resulting in long-term deficits in executive function and behavioral regulation. Inhibitory control impairments are among the most prominent deficits observed in Fetal Alcohol Spectrum Disorder (FASD). This study investigated the neural mechanisms of inhibitory dysfunction using a multimodal MEG–DTI approach in 67 children aged 6–8 years (34 with FASD, 33 controls) who performed a Go/No-Go task. Source-level MEG analyses revealed reduced stimulus-locked cortical activation in the anterior cingulate cortex and significant group-by-hemisphere interactions in the superior parietal cortex and cuneus. Time–frequency analyses showed diminished response-locked beta power in the sensory-motor …

Rational adjuvant selection is a systematic approach based on adjuvant-mediated immunomodulation to identify safe vaccine regimens that enhance protective immunity. Transmitted through ticks and caused by the bacterium Borrelia burgdorferi (Bb), Lyme disease (LD) is the most common vector-borne disease in the Northern hemisphere. There are no approved human vaccines, making it suitable for testing the concept of rational adjuvant selection. Here, we formulated our previously developed and effective LD vaccine antigen, CspZ-YAC187S, with different adjuvants suitable for human use; we analyzed the immune response by transcriptomics and tested the vaccine efficacy after Bb infection. We identified Alum-CpG and Alum-αGal …

Birth Control Use Alters Memory For A Stressful Experience, Julia N. Gross, Kristie Payment, Boyd R. Rorabaugh, Phillip R. Zoladz

Aurora

Hormonal birth control methods are widely used; however, some users suffer considerable side effects. Previous research suggests oral contraceptive users exhibit a blunted cortisol response to psychosocial stressors and alterations in emotional memory, including differential recall of emotional images and details of emotional stories. However, no studies have examined how birth control influences memory for a stressful experience.

The present study analyzes data previously collected from female undergraduate students. In this study, participants reported contraceptive use, then underwent a modified version of the Trier Social Stress Test (TSST) or the friendly-TSST (f-TSST). The TSST required participants to deliver a ten-minute, …

Quality Improvement (Qi) Project Aimed At Reducing Unnecessary Antibiotic Usage Among Older Adult Patients By Addressing Inappropriate Antibiotic Prescribing In Primary And Long-Term Care Settings, Pamela M. Thomas

Seton Hall University Dissertations and Theses (ETDs)

Antibiotic overuse among older adults remains a significant patient safety and public health concern. Recent national data indicate that approximately 30%–50% of outpatient antibiotic prescriptions may be unnecessary, particularly for viral or self-limiting conditions (Chua et al., 2021). Antimicrobial resistance has been associated with more than 1.27 million deaths globally (Murray et al., 2022). This quality improvement project evaluated a multifaceted antimicrobial stewardship intervention in primary and long-term care settings. Baseline review of 167 antibiotic cases revealed 37.1% were inappropriate or questionable, and 28.7% lacked adequate diagnostic documentation. The intervention incorporated provider education, electronic health record decision-support tools, audit and …

UNLV Theses, Dissertations, Professional Papers, and Capstones

Regular exercise and physical therapy are known to increase production of neurotrophins, including brain-derived neurotrophic factor (BDNF), and anti-inflammatory cytokines. These changes combine to theoretically protect and slow the progressive loss of neurons in Parkinson’s disease (PD). The purpose of this study was to examine the effect of exercise and physical activity on various anti-inflammatory and pro-inflammatory cytokines and neurotrophins in people with PD (PwP). This was a cross-sectional design involving PwP (n=37), aged 43-85 years, who participated in two 30-minute bouts of exercise (with brief rest breaks during and pre/post blood draws) separated by a week. Measures collected prior …


Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam May 2026

Effectiveness Of Cognitive Stimulation Therapy On The Quality Of Life Of Adults With Dementia: A Secondary Analysis, Evelyn Airam

UNLV Theses, Dissertations, Professional Papers, and Capstones

This secondary analysis study evaluated the effectiveness of Cognitive Stimulation Therapy (CST) on quality of life (QoL), depressive symptoms, and cognitive function in 108 community-dwelling older adults with cognitive impairments, including dementia. Outcomes involved Quality of Life (QoL) measured by the Quality of Life in Alzheimer’s Disease (QoL-AD), symptoms of depression by the Cornell Scale for Depression in Dementia (CSDD), and cognitive function using the Saint Louis University Mental Status (SLUMS). After the CST, significant improvements were observed in QoL (p = .004), depressive symptoms (p = .002), and cognitive function (p < .001), with small effect sizes. Additionally, a significant interaction between sex and dementia diagnosis status was found in predicting cognitive changes, suggesting that the relationship between dementia diagnosis and cognitive improvement differs by sex. No between-group differences were found for QoL or depression. Findings support CST as a multidimensional, non-pharmacological intervention that improves cognitive, psychological, and social outcomes. Although effects were small, consistent improvements are clinically meaningful given the progressive nature of dementia. This study extends existing literature by demonstrating CST’s effectiveness in a community-based setting and reinforces its alignment with occupational therapy’s emphasis on participation and holistic care. Results highlight the need for early intervention and expanded access to CST programs to enhance quality of life in this population.


Thermal Physiological Ecology Of The Relict Leopard Frog At Hot And Cold Springs, Robert P. Pelletier Iii May 2026

Thermal Physiological Ecology Of The Relict Leopard Frog At Hot And Cold Springs, Robert P. Pelletier Iii

UNLV Theses, Dissertations, Professional Papers, and Capstones

The relict leopard frog (Rana onca) once ranged across drainages in southern Nevada, northwestern Arizona, and southwestern Utah. Following a decline, the species only persisted in a few geothermally influenced hot springs, which led to the perspective that hot springs were high-quality habitat. Rana onca has been under intensive, multiagency management and the species has been translocated to establish additional populations, including at cold-water sites. Three research studies are presented into the thermal physiological ecology of R. onca with the aim of informing conservation strategy. The research was focused at a thermally influenced hot spring and a cold-water spring to …


The Making Of An Extremist: How Do We Become Someone Else’S Nightmare?, María Paula Morales May 2026

The Making Of An Extremist: How Do We Become Someone Else’S Nightmare?, María Paula Morales

The Confluence

This article explores how ordinary people can be pulled into extremist movements and what psychological forces drive that process. It looks at three perspectives: social identity theory, which explains how group belonging shapes behavior, identity development, which shows how people searching for meaning may find it in extremist causes; and social neuroscience, which connects radicalization to brain activity linked to fear, loyalty, and moral judgement. Together, these approaches show that radicalization is not simply about ideology but about identity, emotion, and belonging. By understanding these dynamics, we can find better ways to prevent extremism and promote healthier, more inclusive communities.
