"I'Ve Never Felt A Pain Like This" A Dialogic Analysis Of Parent-Child Estrangement Narratives On Reddit, Grant W. Lane

Graduate Student Theses, Dissertations, & Professional Papers

How do adult children estranged from their parent(s) create meaning and make sense of their estrangement in Reddit posts on the subreddit r/EstrangedAdultChild? This study analyzed Reddit posts written by estranged adult children for a presumed audience of other estranged adult children. Using relational dialectics theory (RDT) as a lens for analysis, this research examined the competing discourses that influence the meaning-making and sense-making processes of estranged adult children in their posts when the intended audience is fellow estranged adult children. Seventy-four posts from r/EstrangedAdultChild, authored by adult children who self-identified as estranged from at least one parent, were collected …

Trace Level Benzoylecgonine Detections In Equine Plasma/Serum – A Proposed Interim Plasma Level Regulatory “Cut-Off“, Andreas F. Lehner, Kimberly Brewer, Levent Dirikolu, Abelardo Morales Briceñod, Robert Holland, George Maylin, Clara Fenger, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Cocaine is a widely used human recreational substance routinely transferring at pharmacologically irrelevant trace level amounts to non-user humans and horses. Horses and humans rapidly demethylate cocaine to benzoylecgonine which is excreted in urine at concentrations approaching two thousand times higher than the corresponding plasma cocaine concentrations. In human workplace drug testing, these usually pharmacologically irrelevant trace level urinary detections of benzoylecgonine are handled by application of a 100 ng/ml urinary “cut-off“, as presented by the Substance Abuse and Mental Health Services Administration (SAMHSA). In horse racing several American states have long used published urinary “cut-offs“ for benzoylecgonine of from …

Intercellular Mitochondrial Transfer Contributes To Microenvironmental Redirection Of Cancer Cell Fate, Julie Sofie Bjerring, Yara Khodour, Emilee Anne Peterson, Patrick Christian Sachs, Robert David Bruno

School of Medical Diagnostics & Translational Sciences Publications

The mammary microenvironment has been shown to suppress tumor progression by redirecting cancer cells to adopt a normal mammary epithelial progenitor fate in vivo. However, the mechanism(s) by which this alteration occurs has yet to be defined. Here, we test the hypothesis that mitochondrial transfer from normal mammary epithelial cells to breast cancer cells plays a role in this redirection process. We evaluate mitochondrial transfer in 2D and 3D organoids using our unique 3D bioprinting system to produce chimeric organoids containing normal and cancer cells. We demonstrate that breast cancer tumoroid growth is hindered following interaction with mammary epithelial cells …

Secondhand Tobacco Smoke Exposure And Sleep Disturbance In School-Aged Children In Appalachian Ohio, Ketrell Mcwhorter, Christine Kim, Timothy J. Hilbert, Danielle E. Mcbride, Anthony A. Mangino, Patrick J. Parsons, Kurunthachalam Kannan, Erin N. Haynes

Epidemiology and Environmental Health Faculty Publications

Introduction: Secondhand tobacco smoke (SHS) exposure remains a major public health concern for children and has been implicated in sleep disturbances through biological and behavioral mechanisms. Different methods of measuring SHS exposure have yielded inconsistent results. This study examined the relationship between SHS exposure and sleep among rural Appalachian 7–9-year-olds, utilizing three SHS measurements: natural log-transformed (ln) serum cotinine concentrations, dichotomized serum cotinine levels (≥0.05 vs. <0.05 ng/ml), and parent/caregiver report of ≥1 smoker in the home. We hypothesized SHS-exposed children would have a significantly higher prevalence of sleep disturbance—e.g., short sleep, frequent snoring, night awakenings—compared to unexposed, regardless of measurement method. Methods: We used data from the Marietta Community Actively Researching Exposure Study, a cohort of 404 children in Marietta and Cambridge, Ohio. Sleep disturbances were parent/caregiver-reported. Linear models were used for continuous outcomes to estimate beta coefficients; log-binomial models with generalized estimating equations (exchangeable correlation) were applied for dichotomized outcomes to estimate prevalence ratios (PR), each with 95% confidence intervals (CI). Results: Twenty-six percent of children had a parent/caregiver report of ≥1 sleep disturbance. There was a 35% increased prevalence of short sleep [PR = 1.35 (95%CI:1.02–1.80), p =.04] with each unit increase of ln serum cotinine levels, adjusting for age, sex, parent education, BMI percentile, and history of breathing difficulties in the past two years. Increasing ln serum cotinine levels were associated with a significant 5.5-min decrease in average sleep duration in age-adjusted models. Conclusions: Higher SHS exposure was associated with poorer sleep outcomes, with serum cotinine emerging as the only measure linked to short sleep, underscoring the importance of smoke-free environments, particularly in rural communities, and objective exposure assessment.

Oral Anticoagulation In The Era Of Continuous Rhythm Monitoring, Chu-Pak Lau, Hung-Fat Tse

Journal of the Hong Kong College of Cardiology

Background

Primary prevention of stroke using oral anticoagulants (OACs) is indicated for clinical atrial fibrillation (AF) documented on standard electrocardiogram (ECG) in those patients with a high risk of stroke. The recent availability of both external ECG monitors (either using consumer electronic or medical devices) and implantable devices have enabled earlier AF episodes to be detected before clinical AF become manifest. These episodes, often termed subclinical AF (SCAF), represent an area of controversy for the application of OAC.

Objective

The present review summarises the management of SCAF, based on recent guidelines and publications in the following areas:

Finite Element Modeling For Two-Dimensional Wireless Capsule Endoscope Manipulation System, Wael S. Abbas, Mohamed T. El-Wakad, R.R. Darwish

Trends in advanced sciences and technology

The inadequacies of traditional flexible endoscopes used in gastrointestinal diagnostic procedures, causing pain and discomfort to patients, led to the development of the wireless capsule endoscope. There are two types of wireless capsule endoscopes: passive and active. The passive wireless capsule endoscope cannot stop at a specific position for diagnostic purposes, which can lead to capsule retention. The active capsule can solve those problems. In this article, we use COMSOL Multiphysics to simulate a two-dimensional (2D) electromagnetic actuation (EMA) system for active wireless capsule endoscope. The EMA system uses a stationary two-pair coil system (Helmholtz and Maxwell). The capsule endoscope …

Complex Plant Disease Syndromes Induced By Plant Parasitic Nematodes And Phytopathogenic Bacteria: Interactions, Mechanisms And Management, Atef M. El-Sagheer, Eman A. Hammad, Radwa G. Mostafa

Trends in advanced sciences and technology

Plant-parasitic nematodes (PPNs) are among the most significant agents contributing to plant disease complexes, acting both as direct parasites and as facilitators of bacterial infections. Their interactions with phytopathogenic bacteria are multifaceted, involving mechanical wounding caused by stylet penetration, disruption of plant cell integrity, and alteration of host physiology. These changes create favourable conditions for bacterial entry, colonization, and systemic spread. Additionally, PPNs can suppress plant defines responses and modify root exudate profiles, thereby enhancing bacterial survival and virulence in the rhizosphere. Such interactions often lead to a synergistic increase in disease incidence and severity, resulting in greater yield losses …

Genetic Mutations Affecting Dentin Formation: Molecular Insights And Therapeutic Strategies, Mohamed Yehia Abdelfattah, Yara Sameh Said, Shimaa A. Elsaady, Shahenda A. Abdallahahmed, Wael Abou-Zeid

Trends in advanced sciences and technology

Writing a comprehensive review on gene mutations affecting dentin mineralization requires thorough research and organization, as each section examines how specific mutations influence this process, supported by relevant findings. Mutations in genes such as DSPP, DMP1, andMEPE impair dentin structure and mineralization by disrupting odontoblast function, dentin matrix integrity, and mineral deposition. These genetic alterations interfere with key biological processes, including odontoblast differentiation and matrix formation, through altered signaling pathways such as Wnt/β- catenin and TGF-β, contributing to dental disorders like Dentinogenesis Imperfecta (DI). Gaining molecular insights into these disruptions enhances our understanding of dentin biology and supports early diagnosis, …

Supporting Second-Year College Students In The Murky Middle, Alisha L. Kimble

University of the Pacific Theses and Dissertations

This study articulates the needs and expectations of an intersectional population of undergraduate college students: second-year students in the murky middle. Nearly half of all student dropouts occur after the first year of enrollment, with more than 45% occurring by mid-performing students. Despite this, institutions, like researchers, do not readily focus on the retention of this population of students; a Noel Levitz study (2013) found a disparity in the prevalence of retention practices for first-year students (94%-98%) and second-year students (20%-29%). This general qualitative study utilized a semi-structured interview protocol with nine participants to gather information about the participants’ needs …

The Development Of A Children’S Book Designed To Use Bibliotherapy And Mindfulness Skills To Promote Interoception In Young Children With Insecure Attachment As A Result Of Adverse Childhood Experiences, Zenaida Agramonte

University of the Pacific Theses and Dissertations

One third of children in the United States have experienced trauma known in the literature as Adverse Childhood Experiences (ACEs). The long-term outcomes of ACEs have a higher likelihood of reducing interoceptive awareness—the ability to sense internal body signals like heart rate, hunger, pain, and emotions. Research suggests that interventions, such as mindfulness and attachment therapies are useful for increasing interoceptive awareness, regulating emotions, and fostering secure attachment in adults. However, apart from attachment, interventions are lacking for young children. Bibliotherapy is one such intervention designed for young children which potentially fosters secure attachment between child and adult storytellers and …

Using Secreted Biomarkers In The Development Of The Detection Of Advanced Cancer Screening System, Elaine Vanterpool

Student Posters

An estimated 20 million people globally develop cancer every year. Furthermore, over 9.7 million people die from cancer. The best prognosis of cancer occurs when detected early. Cancer, in its early stages, usually does not display clinical symptoms and is usually not detectable by symptoms and is diagnosed later. The goal of the D.A.C.S. is to provide a screen that can detect cancer. It is hypothesized that developing a cancer detection system/technology, named D.A.C.S. (Detection of Advanced Cancer Screening) system, can help with early cancer detection, while still being affordable for the general public.

Irritable Bowel Syndrome is a disease linked with the gastrointestinal system and seen to cause bloating, abdominal pain, and harmful alterations in the digestive system. Its cause is complex and is known to have both environmental and genetic factors. Recent studies have shown that IBS occurs due to genetic variations, which leads to the pathogenesis of IBS. One gene, the EED (Embryonic Ectoderm Development) gene has been involved in various biological processes, particularly gastrointestinal functions. The purpose of this study is to explore the potential relationship between the EED gene and IBS.

Analyzing The Inhibition Of Chemical Compounds On Collagenase In P. Aeruginosa, Elaine Vanterpool, Marielle Cooper, Kiara Cameron

Student Posters

Pseudomonas aeruginosa is an opportunistic pathogen that poses significant challenges in clinical treatment due to its production of collagenase. This bacterium can cause several infections including pneumonia, meningitis, septicemia, and a host of other diseases. Collagenase acts as a key virulence factor by breaking down collagen in the host’s extracellular matrix, allowing bacteria to invade tissues. This study hypothesized that the effects of cell secreted collagenase would be inhibited by metronidazole, vanillin, and silver nanoparticles to reduce the pathogenicity of Ps. aeruginosa related infections.
