Barrett’S Esophagus-Associated Genetic Loci In African Americans: A Case-Control Study Using The All Of Us Research Program, Ashwin Rao, Jinyoung Byun, Aaron P Thrift, Hashem B El-Serag

Faculty, Staff and Students Publications

Background and aims: Barrett's esophagus is the only known precursor lesion to esophageal adenocarcinoma (EAC). Barrett's esophagus and EAC are less common in African Americans than in non-Hispanic Whites. Studies in European populations have identified Barrett's esophagus-associated risk loci; however, none have examined loci in African Americans cohorts. We conducted a case-control targeted replication study to investigate previously identified Barrett's esophagus risk loci in an African Americans cohort in the All of Us (AoU) Research Program.

Methods: We abstracted phenomic and genomic data from 108 African Americans with Barrett's esophagus and 778 African Americans controls in the AoU database. We …

Treatment Of Obsessive-Compulsive Disorder Via Mental Health Technology, Erika S Trent, Nisha Jagannathan, Eric A Storch

Faculty, Staff and Students Publications

Obsessive-compulsive disorder (OCD) is a debilitating neuropsychiatric disorder that remains chronic unless intervened with evidence-based intervention. Cognitive behavioral therapy (CBT) with exposure and response prevention is the gold-standard psychological intervention for OCD, but many individuals do not receive this intervention due to barriers to accessing treatment. Mental health technology tools such as telehealth, computerized programs, internet-delivered CBT, and mobile applications have been adopted to expand the accessibility of CBT. An up-to-date summary of the evidence base of technology-mediated formats of CBT for OCD treatment is provided. Clinical benefits offered by such approaches, current limitations, and future research directions are discussed.

Rooted In Hillsboro: An Urban Tree Protection Project, Leandre Mills, Aidan Mcclinton, Aria Shopbell, Karl Coppock, Wally Mcallister

Master of Urban and Regional Planning Workshop Projects

The Canopi team and the City of Hillsboro Urban Forestry Program completed this project to evaluate and strengthen municipal tree protection policies. Current regulations rely heavily on tree replacement rather than retention, contributing to loss of mature canopy and reduced climate, infrastructure, and equity benefits. In many cases, mature trees removed during development or infrastructure projects are replaced with small-caliper plantings that do not provide equivalent environmental or community value for decades.

As Hillsboro grows, the city faces increasing climate pressures, including urban heat island effects, stormwater impacts, invasive pests, and uneven canopy distribution across historically underserved neighborhoods. These challenges …

Over the past 15 years, genetic studies of psychiatric disorders have provided important insight into the contribution of both common variants of small effect, as well as rare exonic and copy number variants with large effect sizes. Genome-wide association studies (GWAS) allow us to understand the intricate polygenicity characteristic of many psychiatric disorders. However, a considerable proportion of single nucleotide polymorphisms (SNPs) implicated in these disorders localize to the non-coding regions of the genome. Unraveling the molecular mechanisms that underlie the etiology of psychiatric illnesses requires integration using functional genomics approaches. Functional genomics methods are critical for developing a mechanistic …

BACKGROUND:

Identifying genetic variants conferring resilience to Alzheimer’s disease and related dementia (ADRD) may hold promise for developing therapeutics.

OBJECTIVE:

To determine genetic associations with being dementia-free at age 85 (DF85).

METHODS:

We examined genetic associations, using whole genome sequencing data, with DF85 in three Trans-Omics for Precision Medicine cohorts and the Alzheimer’s Disease Sequencing Project Phenotype Harmonization Consortium. We tested common variants individually and aggregation of rare (MAF≤1%) coding and non-coding variants in DF85 participants (n=3,657) against individuals who were not DF85 (n=20,010). We verified associations using a stricter control set who developed dementia before age 85 (n=5,552).

The Hippo pathway effector YAP promotes spontaneous proliferation of Müller glia (MG), suggesting that bypassing Hippo signaling and activating YAP could enhance retinal regeneration. However, whether proliferative adult MGs retain meaningful neurogenic competence remains unclear. Here, using viral delivery of a Hippo-resistant YAP variant to wild-type adult MGs, we achieved transient YAP activation in adult MGs, inducing proliferation followed by cell-cycle withdrawal and differentiation. Intersectional genetic lineage tracing and EdU labeling, combined with transcriptomic analyses, revealed that YAP-activated MGs predominantly regenerate MGs, whereas only a subset gives rise to bipolar cell-like neurons. These results indicate that proliferative MGs acquire a …

Consciousness is a fundamental component of cognition1, but the degree to which higher-order pattern recognition relies on it remains disputed2,3. Here we demonstrate the persistence of oddball discrimination, semantic processing and online prediction in individuals under general-anaesthesia-induced loss of consciousness4,5. Using high-density Neuropixels microelectrodes6 to record both single-unit and local-field-potential neural activity in the human hippocampus while playing a series of tones to anaesthetized patients, we found that hippocampal neurons and local oscillations retained some detection of oddball tones. This effect size grew over the course of the experiment …

Application Of Information Literacy Skills To Everyday Life Information Seeking In College Students: Implications For Instruction, Stephanie Ward, Rachel Dineen, Darren Ilett

Communications in Information Literacy

Academic librarians who teach information literacy (IL) skills hope students will transfer those skills to their information seeking in everyday life. However, there is little evidence that students are transferring what they learn about research to their lives outside college. This study aims to find out what search and evaluation strategies college students who have had IL instruction apply to their own personal information seeking behaviors. To do this, a talk-aloud protocol was used to record participants’ thoughts and actions as they navigated scenarios that required them to select a source that met a non-academic information need. The findings indicate …

Chronic lung allograft dysfunction (CLAD) limits long-term lung graft survival, yet its specific gene expression profiles remain unclear. We performed comprehensive spatial transcriptomic analyses of human lungs from CLAD patients, non-CLAD transplant recipients, and non-transplanted controls. In CLAD, AP-1 target genes, including JUNB and FOS, were significantly upregulated in both the epithelium and endothelium, whereas anti-fibrotic genes such as A2M and surfactant proteins (SFTPA1,2) were upregulated in non-CLAD. The lymphocyte population in CLAD was predominantly composed of T cells, with elevated JAK3-IL7R signaling. TNF and IL-17 signaling pathways were commonly activated in both the epithelium and endothelium, with JUNB and …

Generation And Characterization Of Twist1 Acetyl-Mimic And Acetyl-Deficient Mouse Models, Mary Elmeniawi, Xiaobin Yu, Samuel Wen, Gunjan A Bhatia, Lan Liao, Jianming Xu, Walid D Fakhouri

Faculty, Staff and Students Publications

TWIST1 encodes a highly conserved basic helix–loop–helix transcription factor essential for embryonic development from Drosophila to humans. TWIST1 activity is regulated by post‐translational modifications, including phosphorylation during development and cancer metastasis. Recent cancer studies identified acetylation of lysines K73 and K76 as a novel regulatory modification that shifts TWIST1 from a repressive to an activating state during epithelial‐to‐mesenchymal transition (EMT). However, the developmental and in vivo functions of TWIST1 acetylation remain unknown. To investigate the physiological role, we generated the first acetyl‐deficient Twist1 K73,76R K73,76R and acetyl‐mimic Twist1 K73,76Q K73,76Q mouse models using CRISPR/Cas9‐mediated genome editing. Targeted sequencing confirmed substitutions, …

Anterior Cutaneous Nerve Entrapment Syndrome From Glucagon-Like Peptide-1 Receptor Agonist Injection, Neha Singh, Elisa Chaparro, Jordan Michael Shapiro, Emanuel Narcis Husu

Faculty, Staff and Students Publications

Anterior cutaneous nerve entrapment syndrome (ACNES) is an underdiagnosed cause of abdominal pain. We report the first documented ACNES case following subcutaneous administration of glucagon-like peptide-1 receptor agonist. A 44-year-old man developed focal, neuropathic abdominal pain coinciding with initiation of tirzepatide injections. Clinical examination confirmed ACNES diagnosis, and pain improved after relocating injections away from the abdomen and initiating multimodal pharmacotherapy. This case emphasizes the need to consider ACNES in patients endorsing focal abdominal pain with concurrent use of glucagon-like peptide-1 therapy and highlights injection site modification as a simple, effective management strategy while exercising self-restraint with respect to workup.

As digital communication becomes unavoidable at work, notifications have become one of the most common and overlooked sources of interruption. Drawing from current technostress literature, this study investigates how notifications impact acute and perceived stress as well as task speed and accuracy. In an experimental setting, employed university students (N = 35) completed a data-entry task while receiving either no notifications, task-relevant notifications or task-irrelevant notifications to examine how different types of digital interruptions influenced stress and performance. Stress was measured through a pre- and post-task survey and performance was assessed through both speed and accuracy. Although results showed significant …

The Dolor: How A Generation Of Women Quietly Lost Their Children, Alexis Mclean

University Honors Theses

This thesis is an exploration of the phenomenon of increased adoption rates between the years of 1945 and 1973 and attempts to establish a cohesive explanation for and image of the experience of these birth mothers. My research found that adoptions during this time period are generally characterized by the utilization of maternity homes, coercion, and secrecy. The typical birth mother during this time was white and middle class, emblematic of the motivations of their adoptions: to maintain an idealist image of their motherhood and maintain socioeconomic status. Despite this position framed by privilege, these women too often report having …

Birth Satisfaction, As Measured By The Birth Satisfaction Scale–Revised (Bss-R), And Its Role In Predicting Breastfeeding Duration, Maternal-Infant Attachment, And Postpartum Depression, Molly Parker

University Honors Theses

Birth satisfaction has been consistently associated with improved maternal outcomes such as reduced postpartum depression (PPD), stronger maternal-infant attachment, and longer breastfeeding duration. However, the extent to which birth satisfaction independently predicts these outcomes remains unclear. This study examined whether birth satisfaction, as measured by the Birth Satisfaction Scale–Revised (BSS-R), predicts postpartum depression, maternal-infant attachment, and breastfeeding duration in a longitudinal cohort.

Data were drawn from the Prenatal Environmental And Child Health (PEACH) study. Birth satisfaction was assessed at 12 months postpartum using the BSS-R. Postpartum depression was measured using the Edinburgh Postnatal Depression Scale (EPDS), maternal-infant attachment using the …
