Sox2 Regulates Foregut Squamous Epithelial Homeostasis And Is Lost During Barrett’S Esophagus Development, Ramon U Jin, Yuanwei Xu, T Mamie Lih, Yang-Zhe Huang, Toni M Nittolo, Blake E Sells, Olivia M Dres, Jean S Wang, Qing K Li, Hui Zhang, Jason C Mills

Faculty, Staff and Students Publications

Esophageal adenocarcinoma is increasingly prevalent and is thought to arise from Barrett's esophagus (BE), a metaplastic condition in which chronic acid and bile reflux transforms the esophageal squamous epithelium into a gastric-intestinal glandular mucosa. The molecular determinants driving this metaplasia are poorly understood. We developed a human BE organoid biobank that recapitulates BE's molecular heterogeneity. Bulk and single-cell transcriptomics, supported by patient tissue analysis, revealed that BE differentiation reflects a balance between SOX2 (foregut/esophageal) and CDX2 (hindgut/intestinal) transcription factors. Using squamous-specific inducible Sox2-KO (Krt5CreER/+ Sox2Δ/Δ ROSA26tdTomato/+) mice, we observed increased basal proliferation, reduced squamous differentiation, and expanded metaplastic glands at …

A Study Of Wear Measurement And Life Prediction Of Insert Chute Liner On Gold Ore Processing, Ferry Ardika Natanael, Nony Maulidya, Dedi Priadi

Journal of Materials Exploration and Findings

Chutes are critical materials handling assets to transport solid particles from one process step to another in mineral processing, coal mining and cement industries. The material transport, because of material characteristics, cause severe wear on internal lining of chutes or bins’ structure. The wear problem on internal lining of bins or chutes needs to be checked to keep production efficiency. Therefore, not checked wear rate causes liner replacement schedule becomes unpredictable. It leads to production loss and highly cost maintenance in industry. This study shows that condition-based maintenance through regular thickness measurement using Ultrasonic Transducer (UT) to predict life service …

Autonomous Uav Swarm Formation Utilizing Gradient-Driven Contour Mapping For Radiation Source Localization, Edgar Amalyan

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis presents a drone swarm for radiation mapping to aid source localization. The Department of Energy advocates employing UAVs for this task, but existing approaches remain inefficient and impractical in real-world scenarios. Three custom drones are built and flight-tested. A control algorithm to follow a contour, a constant-intensity path, is designed using a gradient fit. By knowing the source’s direction, the drone swarm can fly in the optimal trajectory at every step, leaving nothing to assumption. A program is created that implements formation flight and autonomous navigation. It is tested via a software-in-the-loop simulation utilizing radiation sources and detectors …

An Examination Of The Purity Culture Beliefs Scale And The Interaction Of Religiosity, Purity Culture Beliefs, And Pornography Use In A Census-Matched United States Sample, Kaelyn R. Griffin

UNLV Theses, Dissertations, Professional Papers, and Capstones

The impacts of purity culture have been documented in the prevalence of abstinence-only sex education, perception of personal value tied to virginity, and shame and guilt related to sexual behavior. Similarly, models of moral incongruence often examine religiosity as a contributor of distress related to sexual behavior and pornography use, likely tapping into the influence of purity culture without directly naming its presence. This distinction is crucial due to the variety of religious beliefs and practices, some including purity culture and those without sexually restrictive beliefs and practices. Despite this, standardized measures for researching purity culture are limited. Ortiz (2018) …

Ecological Momentary Assessment Of Mood, Affect, And Perceived Criticism: Investigation Of Daily Patterns And Family Impact, Kayla Mcginty

UNLV Theses, Dissertations, Professional Papers, and Capstones

Perceived criticism (PC) is a component of expressed emotion (EE) that assesses an individual’s perceptions of the criticism that they are exposed to within their interpersonal relationships. PC is elevated among individuals with mood disorders, and mood and mood symptoms act as both a predictor and an outcome of PC. However, few studies have examined the relationship between PC and affect, a more momentary measure of emotion that can serve as a guide to underlying mood. Additionally, limited research has examined how PC within family relationships compares to other interpersonal interactions. Understanding the relationship between momentary affect and PC and …

Error Processing In Psychopathy: An Analysis Of Event Related Brain Potentials And Post-Error Task Behavior, Ananda Liz Peixoto Couto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Performance monitoring and error processing are crucial for learning from mistakes, adjusting responses, and adapting to the environment. Individuals with psychopathy present with failures in performance monitoring, particularly a failure to learn from experience, and error processing deficits have been reported in this population. Error processing literature has investigated its underlying mechanisms via two prongs, namely behavioral measures and electroencephalography (EEG) indicators. Behaviorally, error processing literature has focused on post-error slowing (PES) and post-error accuracy (PEA). Meanwhile, EEG research has identified two components of error-related brain potentials (ERPs) in error processing: error-related negativity (ERN) and error positivity (Pe). This study …

The Compositional And Dynamical Properties Of Exoplanets, Cody James Shakespeare

UNLV Theses, Dissertations, Professional Papers, and Capstones

The solid surface density profile of protoplanetary discs, and the composition of these solids, can be formed through sequential condensation models of dust precipitating from the cooling gas of the solar nebula. I continue developing a code that reproduces the chemical compositions of most chondrites as well as the bulk compositions of the rocky planets using our partial condensation model with an evolving disc. I extend this validated code to exoplanet systems with different initial elemental ratios, like the carbon-to-oxygen ratio and estimated stellar abundances over the age of the universe. I have improved this dust condensation code to include …

Understanding The Role Of Drug Offenses And The Death Penalty In Iran, Cyrus Zarganj

UNLV Theses, Dissertations, Professional Papers, and Capstones

Since the 1979 revolution, the Islamic Republic of Iran has been governed by Islamic laws devised by Shia Muslim clerics, significantly influencing the nation's legal framework in both criminal and civil contexts. The death penalty in Iran covers a broad spectrum of offenses, many of which would not be considered capital crimes or even crimes globally. This extensive application of the death penalty is an instrument of social control during periods of political tension, indicating a direct relationship between the regime's stability and the enforcement of extreme punitive measures. Despite some reduction in the visibility of executions due to international …
