Sex Differences In The Use Of Cognitive Strategies In Brown-Headed Cowbirds (Molothrus Ater), Nicole E. Robinson Ms.

Theses and Dissertations (Comprehensive)

Cognition is widely believed to be adaptive, yet few studies directly show that variation in cognitive performance is related to fitness. Brown-headed cowbirds (Molothrus ater) provide a powerful system for addressing this gap because brood parasitism creates strikingly different reproductive problems for females and males. Females face the spatial demands of nest-prospecting, whereas males face social and competitive demands associated with access to mates. Across five experiments, cowbirds were tested on an outdoor foraging task designed as an analogue of nest prospecting, with manipulations of retention interval, cue conflict, and breeding condition, followed by observations of reproductive behaviour. …

The Power Of Letting Go: The Role Of Goal Adjustment Capacities Across Future And Daily Perspectives Of Chronic Illness, Alexandra Dagher, Meaghan Barlow

Theses and Dissertations (Comprehensive)

Goal adjustment capacities are self-regulatory processes that protect psychological well-being by allowing individuals to disengage from unattainable goals and reengage in new attainable ones. Although research has shown that these capacities are beneficial in the context of chronic illness, little is known about how their effectiveness may differ across various aspects of the chronic illness experience. The present research consisted of two distinct yet complementary studies examining the role of goal adjustment capacities in two chronic illness contexts. Study 1 (N = 149) prompted participants to imagine the future progression of a chronic illness, whereas Study 2 (N …

Pharmacogenetic Hslco1b1*14-Guided Dosing Of Methotrexate In Transgenic Arthritic Mice Normalizes Exposure And Response., Felicia Gooden, Brennan D. Meier, Griffin D. Shaffer, Kim Gibson, Paul Toren, Nieko C. Punt, Sandhya Subash, Dilip K. Singh, Bhagwat Prasad, Laura Ramsey, Zachary L. Taylor

Manuscripts, Articles, Book Chapters and Other Papers

Juvenile idiopathic arthritis (JIA) is a chronic autoimmune disease that negatively affects ~100,000 children under the age of 16 in the United States. About ~30% of these patients fail first-line drug therapy with low-dose methotrexate (MTX) due to poor tolerability or lack of efficacy. The SLCO1B1*14 allele is associated with increased MTX clearance and has been linked to reduced overall drug exposure and nonresponse to MTX in JIA patients. Herein, we describe transgenic hSLCO1B1*14 and hSLCO1B1*1 DBA1/J mSlco1b2 knock-out mice, which we used to assess arthritic response to MTX using the collagen-induced arthritis model. Mass spectrometry-based proteomics analysis revealed that …

Mitochondrial diseases are a complex group of conditions exhibiting significant phenotypic and genetic heterogeneity. Genomic testing is increasingly used as the first step in the diagnostic pathway for mitochondrial diseases. We used next-generation sequencing followed by bioinformatic data analysis to identify potentially damaging variants in the POLRMT gene (NM_005035.4) in six new affected individuals. Structural protein analysis predicted the detrimental impact of variants on POLRMT protein structure. Patients show extended phenotypic abnormalities often presenting early in life with features including global developmental delay, cognitive impairment, short stature and muscular hypotonia. This study expands the genetic and phenotypic landscape of mitochondrial …

A Comparison Of Poly(Methyl Methacrylate) And Silorane-Based Cements As Carriers For Local Doxorubicin Delivery., Grahmm A. Funk, Elizabeth M. Menuey, Zachary D. Denton, Dalan M. Pittz, Alejandro Parrales, Tomoo Iwakuma, Kathleen V. Kilway, Terence E. Mciff

Manuscripts, Articles, Book Chapters and Other Papers

Orthopedic osteosarcomas and metastatic lesions can be difficult to treat with systemically delivered chemotherapy agents alone. Following removal of the primary tumor, implantation of cement to fill the lesion is often done to stabilize weight-bearing bones. One of the commonly used treatments to address osteosarcoma is systemic delivery of doxorubicin. Therefore, research on the incorporation and release of efficacious doxorubicin for local delivery from cement is important. Poly(methyl methacrylate) (PMMA)-based bone cements are the gold standard in orthopedics but have inherent disadvantages. Efforts to overcome some of these deficiencies led to the development of a novel silorane-based biomaterial (SBB). This …

The prevalence of iron acquisition virulence genes which contribute to pathogenicity outcomes in these strains has also not been described in detail.Aim. To evaluate bovine lactoferrin's (bLF) effects on the in vitro growth of neonatal septicaemia E. coli isolates, and to determine the presence of iron acquisition virulence …

Identification Of Neural Crest And Melanoma Cancer Cell Invasion And Migration Genes Using High-Throughput Screening And Deep Attention Networks., J C Kasemeier-Kulesa, S Martina Perez, R E Baker, Paul M. Kulesa

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Cell migration and invasion are well-coordinated in development and disease but remain poorly understood. We previously showed that the neural crest (NC) cell migratory wavefront shares a 45-gene panel with other cell invasion phenomena. To rapidly and systematically identify critical genes, we performed a high-throughput siRNA screen and statistical and deep learning analyses to determine changes in NC- versus non-NC-derived human cell line behaviors.

RESULTS: We find 14 out of 45 genes significantly reduced c8161 melanoma cell migration; four of the 14 genes altered leader cell motility (BMP4, ITGB1, KCNE3, and RASGRP1). Deep learning identified marked disruptions in cell-neighbor …

Optimizing Healthy Aging: A Preventative Approach To Support Community-Dwelling Older Adults, Jada Welke

Occupational Therapy Capstones

Introduction: Healthy aging is a complex and multidimensional process influenced by physical, cognitive, psychosocial, environmental, and lifestyle factors across the lifespan. Increasing evidence from researchers suggests that many health care systems continue to rely on reactive models that address decline only after functional limitations emerge. Preventive interventions initiated in midlife have the potential to significantly influence long-term health outcomes, independence, well-being, and quality of life. As a result, there is growing recognition that multidimensional, proactive screening and intervention should begin earlier, before age-related conditions become clinically significant.

Purpose: The purpose of this scholarly project was to address this need through …

Family-Centered Programming For A Rural Midwest Emergency Shelter: An Occupational Lens, Ariel Kathryn Tix

Occupational Therapy Capstones

Introduction: After a period of decline in homelessness, a startling trend reversal occurred between 2023 and 2024; there was a 39% increase in families experiencing homelessness in the United States (de Sousa & Henry, 2024). Rural homelessness is less visible and often looks different from urban homelessness, which presents challenges that require a different approach (Brott et al., 2019). Individuals experiencing homelessness have challenges in every area of occupation and could benefit from novel strategies and resources. Challenges include parenting, accessing medical care, obtaining permanent housing, community mobility, and meaningful routine development (American Occupational Therapy Association, 2020; Brott et al., …

Cultivating Connections: Empowering Agricultural Community Members Through Collaborative Care, Kearyn E. Nelsen

Occupational Therapy Capstones

Background: Agriculture and mental health – two words not typically used in the same sentence; however, considering the rate of suicide among those working in the agriculture profession is significantly higher than the general population, the need for both awareness and action is critically important. Despite a lack of research specific to occupational therapy and the agricultural population, occupational therapists on an interprofessional healthcare team are uniquely positioned to serve this population. Interprofessional collaboration is essential when serving agricultural community members, whose needs involve a complexity of physical, mental, social, and environmental factors, each impacting the overall health and well-being …

Holistic Occupational Therapy Approach In Addressing Women’S Health Needs & Access To Care, Lilja Jurva

Occupational Therapy Capstones

Background: As women across the lifespan experience complex physical, emotional, and occupational challenges related to maternal transitions, mental health needs, chronic conditions, and rural healthcare disparities, occupational therapy is uniquely equipped to address the complex challenges. Services have been proven to be directly correlated to lower incidence of preterm birth, cesarean delivery, low birth weight, excessive gestational weight gain, diabetes mellitus, and hypersensitive disorders, and higher incidence of vaginal delivery. A clear gap for maternal support services was identified in the Grand Forks community through literature review, interviews, and community engagement, leading to the development of NoDak Therapy and Wellness. …

Empowering Caregivers: An Occupational Therapy-Informed Educational Program For Dementia Care In Rural Communities, Maria Lynn Johnson

Occupational Therapy Capstones

Purpose: Hospitalization presents significant risks for individuals with dementia, including increased behavioral and psychological symptoms (BPSD), delirium, functional decline, and reduced occupational engagement (Boltz et al., 2023; Teichmann et al., 2019; Zwingmann et al., 2020). Acute care environments are often overstimulating, unfamiliar, and task-oriented, which can exacerbate cognitive impairment and contribute to caregiver distress. Despite strong evidence supporting nonpharmacological, occupation-based interventions, structured engagement opportunities are rarely integrated into acute care workflows (Burgdorf et al., 2023; Faeder et al., 2023). This doctoral capstone project aimed to develop occupation-based dementia activities for use during hospitalization while equipping formal and informal caregivers with …

This study evaluates the current and future performance of Indiana’s EV charging infrastructure using Multimodal Energy-Efficient Trip Simulation in Real Time (METS-R), a high-resolution simulation platform. Five EV adoption scenarios, ranging from pessimistic to optimistic, are modeled for the years 2024 through 2031, to assess spatial and temporal variations in public charging demand. Results reveal increasing public charging demand under high adoption scenarios, with significant disparities between urban and non-urban areas. Accessibility to public charging is found to be uneven …

Advancing Culturally Sustaining Stem Instruction For Latinx Secondary Students: From Research To Practice Through The Monarch Migration, Maryam Saberi, Noushin Nouri

Teaching and Learning Faculty Publications

This chapter presents the development of a research-based STEM curriculum for Latinx students using Monarch butterfly migration phenomenon as context. Based on a systematic review of 196 articles, the study first maps eight STEM research categories for Latinx populations. It then conducts a meta-synthesis of 23 successful interventions to create a Latinx-Affirming STEM (La-STEM) curriculum framework organized around Akker's ten curriculum elements. Finally, it translates these theoretical foundations into practical implementation through a detailed Monarch butterfly migration curriculum. The Monarch phenomenon, chosen for its deep cultural resonance and scientific richness, demonstrates how each curriculum element can integrate STEM concepts with …

Changing Student Perspectives On Alcohol, Smoking & Vaping Through The Use Of Tetrahymena, Courtney Hausner, Douglas L. Chalker, Alexandra Forgerson, Carol E. Colaninno, Alison Brockhouse, Rachel Ruggirello

Institute for School Partnership: Research & Publications

We describe the redesign and classroom testing of an Advancing Secondary Science Education through Tetrahymena (ASSET) module addressing adolescent alcohol, smoking, and vaping. Using the 5E instructional model, the module has students investigate how alcohol, cigarette smoke extract, and vape extract affect the ciliated protozoan Tetrahymena, an accessible proxy for effects on ciliated human respiratory cells. Students analyze public health data, conduct guided and self-designed investigations, and create outreach posters communicating evidence-based risks to peers. We report on observations from two classroom implementations, describing gains in students' ability to articulate toxicology concepts, connect cellular findings to whole-body health, and express …
