The Role Of Occupational Therapy In Postnatal Mental Health: An Eight-Week Postpartum Program, Paola Quiroz

OT Doctoral Capstones

Postpartum mental health includes various conditions such as postpartum anxiety and postpartum depression amongst others (Barbic Skye et al., 2021). Rates of postpartum depression (PPD) have been increasing in recent years, impacting mothers, children and entire families by changing the way a mother interacts with others (WHO, 2024). Postpartum mothers face unique challenges when transitioning into motherhood resulting in increased maternal stress and ultimately leading to PPD or PPA. Although rates of PPD and PPA are increasing, there is limited research involving non-pharmaceutical treatment options for new mothers.

Occupational therapy (OT) plays a vital role in maternal mental health because …

Reclaiming Control: A Self-Management Education Program For Cancer Survivors, Monica Elisa Gutierrez

OT Doctoral Capstones

Cancer survivors face physical, emotional, and cognitive side effects after cancer treatment which negatively affects their quality of life (QOL).

A remote 6-week self-management program was implemented to educate survivors on how to manage these challenges. Comparison of pre- and post-program surveys demonstrated increased confidence in managing side effects after participation in the program, indicating that self-management interventions can effectively enhance survivors’ symptom management skills. The Self-Management Program is effective in empowering cancer survivors, improving self-efficacy, and enhancing QOL.

Strength-Based Peer Mentoring To Empower Independence For Adults With Autism, Annmarie De La Rosa

OT Doctoral Capstones

Adults with autism face disproportionately high rates of unemployment or underemployment, limited engagement in post-secondary education, and restricted opportunities for social participation. This is largely due to the abrupt discontinuation of services after high school—often referred to as the “service cliff” (Roux, 2015). The loss of structured supports can result in a decline in functional independence, increased mental health concerns such as anxiety and depression, and heightened social isolation (Chun et al., 2023; Schiltz et al., 2021).

This Capstone project aimed to address the unmet post-secondary needs of young adults with autism by implementing a peer mentoring program grounded in …

Optimization Of Proximity Labeling In Endothelial Cells: Overcoming Endogenous Biotin Interference And Cost Barriers, Ying Jiang, Kuizhi Qu, Mengjun Dai, Yan-Ning Rui, Zhen Xu

Faculty, Staff and Student Publications

Proximity labeling has become a powerful technique for mapping protein-protein interactions under physiologically relevant conditions, with TurboID offering high enzymatic activity and rapid labeling. However, its application in endothelial systems has been limited, partly due to the presence of endogenous biotin in specialized media, which reduces labeling specificity. Here, we optimized TurboID-mediated proximity labeling in brain microvascular endothelial cells by addressing two key challenges: endogenous biotin interference and cost-effective depletion. We discovered that endothelial cell medium contains substantial biotin levels, which saturate TurboID labeling and obscure the effects of exogenous biotin. Using High Capacity NeutrAvidin

Mechanisms Of How Sarcopenia Affects Functional Outcomes In Acute Ischaemic Stroke, Dong-Seok Gwak, Jinyong Chung, Dawid Schellingerhout, Hyerin Oh, Sang-Wuk Jeong, Ji Sung Lee, Dong-Eog Kim

Faculty, Staff and Student Publications

Sarcopenia, a common geriatric condition characterized by the loss of skeletal muscle mass and function, can negatively affect functional outcomes in acute ischaemic stroke; however, the underlying mechanisms remain unclear. We hypothesized that sarcopenia affects post-stroke outcomes, mediated through its impact on dysphagia, early neurological deterioration, or post-stroke recovery, particularly in patients with motor deficits. To explore this hypothesis, we included 600 consecutive elderly (≥65 years) patients with acute (< 1 week) ischaemic stroke and assessed: (i) the relationships sarcopenia has with dysphagia, early neurological deterioration and various phases of recovery after stroke (in-hospital, post-discharge [up to 3 months], and chronic [3 months to 1 year]) and (ii) whether either presenting symptoms or lesion locations modify the impact of sarcopenia on stroke outcomes. Temporal muscle thickness, a marker of sarcopenia, was measured by brain magnetic resonance imaging and dichotomized into low versus high temporal muscle thickness at the 25th percentile cut-off point. Logistic regression analysis, mediation analysis and statistical brain mapping were conducted. Mean age was 75.3 ± 6.1 years and 303 (50.5%) were male. Low temporal muscle thickness (< 5.1 mm) was independently associated with dysphagia (adjusted odds ratio 1.89 [95% confidence interval 1.06–3.37], P = 0.03), early neurological deterioration (adjusted odds ratio 2.75 [95% confidence interval 1.61–4.71], P < 0.001) and post-discharge recovery (adjusted odds ratio 0.56 [95% confidence interval 0.34–0.94], P = 0.03) but not with in-hospital or chronic recovery. In addition, dysphagia, early neurological …

Recovery Of Verbal Working Memory Depends On Left Hemisphere White Matter Tracts, Randi C Martin, Junhua Ding, Ali I Alwani, Steve H Fung, Tatiana T Schnur

Faculty, Staff and Student Publications

Researchers propose that the recovery of language function following stroke depends on the recruitment of perilesional regions in the left hemisphere and/or homologous regions in the right hemisphere. Many investigations of recovery focus on changes in gray matter regions, whereas relatively few examine white matter tracts and none address the role of these tracts in the recovery of verbal working memory. The present study addressed these gaps, examining the role of left versus right hemisphere tracts in the longitudinal recovery of phonological and semantic working memory. For 24 individuals with left hemisphere stroke, we assessed working memory performance within 1 …

Ai/Ml-Empowered Approaches For Predicting T Cell-Mediated Immunity And Beyond, Cheng-Chi Chao, Yulun Chiu, Lucas Yeung, Cassian Yee, Chongming Jiang, Xiling Shen

Faculty, Staff and Student Publications

T cells play a dual role in various physiopathological states, capable of eliminating tumors and infected cells, while also playing a pathogenic role when activated by autoantigens, causing self-tissue damage. The regulation of T cell-peptide/major histocompatibility complex (TCR-pMHC) recognition is crucial for maintaining disease balance and treating cancer, infections, and autoimmune diseases. Despite efforts, predictive models of TCR-pMHC specificity are still in the early stages. Inspired by advances in protein structure prediction via deep neural networks, we evaluated AlphaFold 3 (AF3)-based AI computation as a method to predict TCR epitope specificity. We demonstrate that AlphaFold can model TCR-pMHC interactions, distinguishing …

The Primary Cilia: Orchestrating Cranial Neural Crest Cell Development, Hiroyuki Yamaguchi, Matthew D Meyer, William B Barrell, Maryam Faisal, Rebecca Berdeaux, Karen J Liu, Yoshihiro Komatsu

Faculty, Staff and Student Publications

Primary cilia (hereafter "cilia") are microtubule-based antenna-like organelles projecting from the surface of vertebrate cells. Cilia can serve as cellular antennae controlling cell growth and differentiation. Absent or dysfunctional cilia frequently lead to craniofacial anomalies known as craniofacial ciliopathies. However, the detailed pathological mechanisms of craniofacial ciliopathies remain unclear. This perspective discusses our current understanding of the role of cilia in cranial neural crest cells. We also describe potential mechanisms of ciliogenesis in cranial neural crest cells, which may contribute to unraveling the complex pathogenesis of craniofacial ciliopathies.

Inducing Hypertension In Myh11r247c/R247c Mice Triggers Aortic Dissections With Increased Focal Adhesion Kinase Signaling, Callie S Kwartler, Shanzhi Wang, Zhen Zhou, Pujun Guan, Yang Yu, Xue-Yan Duan, Theodore Zhang, Jiyuan Chen, Elaine C Davis, Dianna M Milewicz

Faculty, Staff and Student Publications

Objective: We sought to determine if hypertension in combination with a "variant of uncertain significance" that disrupts protein function, MYH11 p.Arg247Cys, would induce aortic dissections in a mouse model.

Approach and results: Administration of L-NAME via drinking water and a high salt diet increased blood pressure in WT and Myh11R247C/R247C mice and triggered type A dissections with cardiac tamponade in 20% of the Myh11R247C/R247C mice. Myh11R247C/R247C aortas have aberrant smooth muscle contractile unit-elastin connections by transmission electron microscopy, along with increased focal adhesion signaling at baseline, which further increases with hypertension.

Conclusion: Gene-environment interactions trigger aortic dissections in Myh11R247C/R247C mice.

Exploring The Role Of Reward Functioning In The Overlap Of Post-Traumatic Stress And Cocaine Use Disorder, Kate Hull, Hanaan Bing-Canar, Krista Miloslavich, Christopher Holden, Aneet Ahluwalia, Scott D Lane, Joy M Schmitz, Margaret C Wardle

Faculty, Staff and Student Publications

Background: Posttraumatic stress disorder (PTSD) symptoms are common in people with cocaine use disorder (CUD), and even sub-threshold PSTD symptoms result in worse treatment outcomes. Difficulties with reward functioning may drive this comorbidity. Impairments in reward functioning are prominent in both PTSD and CUD and contribute to development of substance use problems after trauma. There are three distinct reward processes that may be involved in the PTSD/CUD overlap: consummatory reward (ability to experience pleasure), motivational reward (willingness to exert effort for rewards), and reward learning (adapting behavior based on reward history). Here we test whether impairments in these reward functions …
