Unique Root Anatomy Of Mandibular Second Premolars: Clinical Strategies For Effective Disinfection And Preservation Of Dentine Structure In Root Canal Treatment-A Case Report, Ji Wook Jeong, Erika Silguero Gonzalez, Scott R Makins, Timothy Kirkpatrick

Faculty, Staff and Student Publications

It is difficult to predict the outcomes of non-surgical root canal treatment (NSRCT) for mandibular second premolars with multiple root canals. In these teeth, the complicated anatomy with fin(s), or a C-shape, and possible secondary canal(s) varies unpredictably. The morphology of the root canals provides shelters for bacteria to remain, regrow, and form biofilms despite the endodontic treatment. Moreover, the prevalence of mandibular second premolars with multiple canals is extremely infrequent. Therefore, the clinical management of NSRCT in such cases is not sufficiently reported. This case report introduces two cases of NSRCT for mandibular second premolars with a radicular groove …

Faculty, Staff and Student Publications

Introduction: The human-derived amnion-chorion membrane (ACM) has endogenous antimicrobial properties, which are important for preventing the colonization and survival of oral bacteria on exposed membranes. This project aimed to decipher the underlying mechanism by identifying the components of ACM that confer antibacterial properties. In addition, the antimicrobial efficacy of these identified components on oral bacteria was assessed.

Methods: Four antimicrobial proteins, histone H2A/H2B, cathelicidin LL-37, lactoferrin, and lysozyme, were identified via mass spectrometry in ACM. These proteins were then assessed for their efficacy in killing Streptococcus gordonii Challis. Log-phased bacterial cells were cultured with the commercially available proteins that were …

Association Of Cancer Diagnosis With Disability Status Among Older Survivors Of Colorectal Cancer: A Population-Based Retrospective Cohort Study, Shiming Zhang, Lin-Na Chou, Michael D Swartz, Hemalkumar B Mehta, James S Goodwin, Yong-Fang Kuo, Sharon Hermes Giordano, Carole A Tucker, Karen M Basen-Engquist, Elizabeth J Lyons, Brian Downer, Susan K Peterson, Tru Cao, Maria C Swartz

Faculty, Staff and Student Publications

BACKGROUND: Older cancer survivors likely experience physical function limitations due to cancer and its treatments, leading to disability and early mortality. Existing studies have focused on factors associated with surgical complications and mortality risk rather than factors associated with the development of poor disability status (DS), a proxy measure of poor performance status, in cancer survivors. We aimed to identify factors associated with the development of poor DS among older survivors of colorectal cancer (CRC) and compare poor DS rates to an age-sex-matched, non-cancer cohort.

METHODS: This retrospective cohort study utilized administrative data from the Texas Cancer Registry Medicare-linked database. …

Racial And Ethnic Differences In Infant Survival For Hydrocephaly-Texas, 1999–2017, Munir Ahmed, Charles Shumate, Heidi Bojes, Ketki Patel, A J Agopian, Mark Canfield

Faculty, Staff and Student Publications

Background: Congenital hydrocephaly, an abnormal accumulation of fluid within the ventricular spaces at birth, can cause disability or death if untreated. Limited information is available about survival of infants born with hydrocephaly in Texas. Therefore, the purpose of the study was to calculate survival estimates among infants born with hydrocephaly without spina bifida in Texas.

Methods: A cohort of live-born infants delivered during 1999-2017 with congenital hydrocephaly without spina bifida was identified from the Texas Birth Defects Registry. Deaths within 1 year of delivery were identified using vital and medical records. One-year infant survival estimates were generated for multiple descriptive …

Factors Associated With Infant Sex And Preterm Birth Status For Selected Birth Defects From The National Birth Defects Prevention Study, 1997–2011, Eva M Williford, Wei Yang, Meredith M Howley, Chen Ma, Ronnie T Collins, Kari A Weber, Dominique Heinke, Julie M Petersen, A J Agopian, Natalie P Archer, Andrew F Olshan, Lindsay A Williams, Marilyn L Browne, Gary M Shaw

Faculty, Staff and Student Publications

Background: Birth defects and preterm birth co-occur, with some overlapping risk factors. Many birth defects and preterm births tend to have a male preponderance. We explored potential risk factors impacting sex and preterm (< 37 weeks of gestation) birth differences among infants with selected birth defects delivered from 1997 to 2011 using data from the National Birth Defects Prevention Study (NBDPS).

Methods: The NBDPS was a large multisite, population-based case-control study. Using random forests, we identified important predictors of male preterm, female preterm, and male term, each compared with female term births for each birth defect. Using logistic regression, we estimated odds ratios for associations between important predictors and sex-preterm birth status by birth defect.

Results: We examined 11,379 infants with nine specific birth defects. The top …

Nonlinear Changes In Facial Affect And Posttraumatic Growth: Assessment Of Ecological Momentary Assessment Video Data, Aaron M. Harwell, David Pincus, Bernard P. Ricca, Emmeline Taylor, Charles C. Benight

Psychology Faculty Articles and Research

Posttraumatic Growth (PTG), characterized by newfound meaning, perspective, and purpose for trauma survivors, remains enigmatic in its nature. This state is thought to arise from the dynamic interplay of biopsychosocial factors; however, the nature of this interplay is unclear. This study aimed to investigate the intricate relationship between PTG and facial affect dynamics, shedding light on the complex interplay of biopsychosocial factors that underpin this transformative process. We conducted a comprehensive investigation involving 19 wildfire survivors who provided daily self-reported PTG ratings alongside smartphone videos analyzed using Automated Facial Affect Recognition (AFAR) software. Our findings revealed compelling evidence of self-organization …

Associations Between Positive Affect And Physical Activity From Young Adulthood To Midlife: A 25-Year Prospective Study, Farah Qureshi, Laura D. Kubzansky, Ying Chen, Jackie Soo, Eric S. Kim, Donald Lloyd-Jones, Julia K. Boehm

Psychology Faculty Articles and Research

Objective: Positive affect may influence health by promoting physical activity, but evidence evaluating this association is mostly cross-sectional and cannot discern directionality. This study used a counterfactual-based framework to estimate the causal effect of positive affect on physical activity patterns over 25 years, accounting for potential reverse associations. Method: Data were from 3,352 participants in the Coronary Artery Risk Development in Young Adults study. Repeated assessments of positive affect and physical activity were collected from 1990 to 2016. Longitudinal associations were evaluated in two ways: (a) using baseline positive affect in traditional linear mixed models that accounted for reverse causal …

Proteoglycans In Mechanobiology Of Tissues And Organs: Normal Functions And Mechanopathology, Mary C Farach-Carson, Danielle Wu, Cristiane Miranda França

Faculty, Staff and Student Publications

Proteoglycans (PGs) are a diverse class of glycoconjugates that serve critical functions in normal mechanobiology and mechanopathology. Both the protein cores and attached glycosaminoglycan (GAG) chains function in mechanically-sensitive processes, and loss of either can contribute to development of pathological conditions. PGs function as key components of the extracellular matrix (ECM) where they can serve as mechanosensors in mechanosensitive tissues including bone, cartilage, tendon, blood vessels and soft organs. The mechanical properties of these tissues depend on the presence and function of PGs, which play important roles in tissue elasticity, osmolarity and pressure sensing, and response to physical activity. Tissue …

Revocation At The Founding, Jacob Schuman

Michigan Law Review

The Supreme Court is divided over the constitutional law of community supervision. The justices disagree about the nature of a defendant’s liberty under supervision, the rights that apply when the government punishes violations, and the relationship between parole, probation, and supervised release. These divisions came to a head in 2019’s United States v. Haymond, where the justices split 4–1–4 on whether the right to a jury trial applies to revocation of supervised release. Their opinions focused on the original understanding of the jury right at the time the Constitution was ratified.

This Article aims to settle the debate over …

Scrutinizing The Bathroom Binary: Equal Protection Theories For Nonbinary Students, Annie Schuver

Michigan Law Review

Over the past decade, transgender students have challenged discriminatory school bathroom policies under the Equal Protection Clause with varying success. But another group of students, facing similar discrimination, has yet to see its day in court. Like their transgender peers, nonbinary students often lack access to gender-appropriate restrooms at school. Many K–12 schools offer only “boys” and “girls” restrooms, ignoring the needs of students who identify as neither boys nor girls, as both of those genders, or as something else entirely. Forced to use sex-segregated bathrooms (or no bathroom at all), nonbinary students suffer adverse health, safety, and educational outcomes. …

Graduate Student Theses, Dissertations, & Professional Papers

The Serban lab has previously developed and reported on a single application drug delivery system for the treatment of otitis externa. Otitis externa also known as outer ear infections is a very common ailment that impacts large portions of both human and domestic animal populations. Typical treatment for otitis externa typically requires an extended dosing regimen over several days that is inconvenient and can lead to poor clinical outcomes due to poor patient compliance. Our delivery system employs a thixotropic gel to deliver a steady dose of medication over the duration of the infection.

Here we evaluated the reproducibility and …

“We’Re Left Picking Up The Pieces:” Use Of Grief Interventions In Rural Schools Since Covid-19 Pandemic, Jennifer Lynn Rotzal

Graduate Student Theses, Dissertations, & Professional Papers

Research has indicated that individuals who have died from the COVID-19 virus will likely leave behind several grieving family members. For every person who dies of COVID-19, it was estimated that they would leave behind 2.2 children and 4.1 grandchildren (Albuquerque & Santos, 2021). The death of a parent or other loved one is often noted as one of the most potentially traumatic experiences for a child. During the COVID-19 pandemic, death became more prominent in hundreds of thousands of children’s lives, having a profound effect on the child, as well as on their family and surrounding community (Griese et …

The Other Identity Politics: Political Turning Points And Political Identity Development In College-Going Emerging Adults, Kaetlyn Jeanette Cordingley

Graduate Student Theses, Dissertations, & Professional Papers

Emerging adulthood is a critical developmental period, especially for identity– the development of our sense of who we are internally and relative to others. This research sought to investigate one understudied aspect of identity development: political identity. Five questions guided this research: first, is political identity related to broader identity development? Second, does political identity development differ based on political ideology (liberal, moderate, conservative)? Third, do individuals’ self-identified political turning point events differ based on political ideology? Fourth, how is political identity development related to political turning point narratives? Fifth, how does meaning making interact with political identity development and …

Zooming In On A Snapshot Of Care: Adapting The Index Of Care For Historical And Modern Individuals In The Terry Collection, Felicia Robyn Sparozic

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation adapts the Index of Care (IOC), traditionally focused on prehistoric contexts, to historical (1840-1950) and modern (post-1950) individuals from the Smithsonian’s Terry Collection, to account for those individuals with extensive records. By introducing sister methodologies for both historical and modern contexts, this research bridges the methodological gap in care analysis, enhancing the original IOC with contextual environmental variables and, for modern individuals, DNA analysis.

The study utilizes a selected cohort from the Terry Collection, emphasizing the investigation of caregiving practices across different sexes and ancestral backgrounds. Contrary to initial hypotheses predicting sex-based differences in care provision, findings show …

Csn-5: A Tumor's Friend Or Foe In The C. Elegans Germline?, Kellie C. Kuch

Graduate Student Theses, Dissertations, & Professional Papers

The COP9 signalosome is a highly conserved eukaryotic complex regulating protein degradation via deneddylation of Cullin-RING E3 ligases. CSN5, the COP9’s fifth component, contains the catalytically active domain for CSN deneddylation. The complex is inactive without CSN5; however, CSN5 engages in COP9-independent binding with several other proteins, typically promoting either destruction or stabilization of its partners. Many of its confirmed interaction partners are also implicated in tumorigenesis (prominent examples being p27 and p53) and a complex cancer interactome has been established for CSN5. Additionally, CSN5 overexpression has been documented in a staggering array of cancers of diverse origins. This discovery …

The Influence Of Sex Hormones On The Physiological Response To Exercise In Females, Katherine Sue Christison

Graduate Student Theses, Dissertations, & Professional Papers

The overall aim of this dissertation was to investigate the influence of female sex hormones on the response to exercise in premenopausal and postmenopausal women. Study one examined the effect of menstrual cycle phase on thermoregulation during prolonged exercise in the heat. Notably, elevated core temperature and basal aldosterone was apparent in the mid-luteal phase corresponding with elevations in estrogen and progesterone. Aldosterone significantly increased following exercise in the heat but remained elevated in the mid-luteal phase, suggesting a previously unexplored menstrual phase-aldosterone hormonal additivity under the stress of uncompensable heat. Study two was a survey-based investigation with the aim …

No Worries, It’S Fine, Lexie E. Loader

Graduate Student Theses, Dissertations, & Professional Papers

In my MFA exhibition, no worries, it’s fine, I depict seemingly mundane objects and places in my paintings to explore underlying themes of the bittersweet. They contain both painful memories and sweet moments, and their complexity gives them authenticity. To only explore the one would be dishonest, as the bitter and the sweet are forever intertwined.

Bittersweet is tied to longing…longing for someone you love when they are not present, for better circumstances while accepting where you are. Longing can propel us forward, one step at a time. It gives us the hope that when we experience pain, the pendulum …

A Soil-Plant-Atmosphere Continuum Model To Simulate Seedling Response To Water Stress, Michael Kurt Kendree Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Most current ecohydrologic models simplify the hydraulics that are at play in plant-water relationships by assuming that the water content within the plant is static. In reality, plants have a relative water content that varies with time in response to environmental stresses. To some extent, variations in plant relative water content are regulated by changes in the osmotic potential of water within plant cells, which contributes to the resilience of plants during periods of water shortage. We present a model that simulates plant water transport and storage within the soil-plant-atmosphere continuum. The model incorporates the role of osmotic regulation in …
