Emotional Content In Working Memory Processes: An Fmri Study., Manal Zafar

Electronic Theses and Dissertations

Working memory (WM) is a dynamic system that processes and manipulates both goal-relevant and goal-irrelevant information, integral to higher-level cognition and executive control (Fujii, 2001; Nyberg & Erikkson, 2016). The processing and manipulation of representations is modulated by the affective nature of the information (Pessoa, 2009) such that negative information can either impair or enhance WM processing. WM impairments are seen commonly across clinical disorders such as depression, anxiety, PTSD and schizophrenia (Levens & Gotlib, 2010; Joorman et a., 2011; Brodziak et al., 2015). Specifically, negative information is known to have differential processing in WM compared to neutral and positive …

Relations Between Discrimination, Negative Attribution Style, Cortisol, And Depressive Symptoms In Adolescents., Hannah Widmer

Electronic Theses and Dissertations

The aim of our study was to integrate the chronic stressor of Perceived Everyday Discrimination (PED) into the Hopelessness Theory of Depression with a focus on the comorbidity between physical and mental health by way of depressive symptoms and cortisol in adolescents. Research has shown that cognitive diatheses mediate the relation between stress and depressive symptoms and cortisol predicts depression. We hypothesized that Negative Attribution Style (NAS) and cortisol would mediate the relation between PED and depressive symptoms. Altogether, 99 adolescents (mean age: 14.10 years, 36.4% female; 63.6% male; ethnicity: 2% Latinx; 98.2 % non-Latinx; race: 41.4% Black, 34.8% White, …

Examining The Role Of Presence Of Meaning In Life On Wellbeing In Emerging Adulthood., Hannah K. Heitz

Electronic Theses and Dissertations

Emerging adults face numerous challenges and stressors, such as financial stress, which often accompanies the experience of educational and occupational transitions. As such, it is important to identify personal resources, or protective factors, to help emerging adults buffer the experience of financial stress. Presence of meaning in life has been identified as a resource that can buffer the negative effects of stressors on wellbeing among adults and adolescents, yet there is little empirical evidence for its moderating effect among emerging adults. There is some evidence in the literature that suggests that emerging adults experience presence of meaning in life differently …

The Role Of Matrix Metalloproteinase-9 Gene Ablation In Preserving Ejection Fraction During Chronic Volume Overload-Induced Heart Failure., Oluwaseun Ebenezer Akinterinwa

Electronic Theses and Dissertations

Heart failure is a prevalent cause of hospitalization globally, especially among older adults. The ejection fraction is a critical parameter in assessing and managing heart failure patients. As we age, the cardiovascular system undergoes changes that increase the risk of cardiovascular morbidity and mortality. One of the most significant structural features that occur with age is reduced or impaired contractility of the left ventricular wall of the heart. Matrix metalloproteinases (MMPs) play a crucial role in tissue remodeling, and their latency is linked with nitric oxide (NO). In the context of heart failure and constant stress, tissue remodeling leads to …

In recent years, deep learning models have shown promise in accurately detecting and characterizing prostate lesions using advanced imaging …

Racial Identity & Psychological Distress: The Mediating Role Of Sense Of Community And Spiritual Struggles Among Black Christians., Adebayo Ajibade

Electronic Theses and Dissertations

Religious practice and church membership have historically been protective and critical in Black communities in the United States and across the African diaspora. Demographic studies have shown a consistent decline in religious adherence and practice across racial and ethnic groups in the United States. However, the decline in religious practice and participation in religious communities has been less pronounced among individuals of African descent. Participation in one’s religious community is often a source of positive social engagement and can foster positive intrapersonal outcomes (e.g., wellbeing). However, religious communities and religious practice can also be the source of conflict and emotional …

Unraveling The Complex Dynamics Of Cardiac Fibrosis: Ccn1 As A Novel Regulator Of Scar Collagen Architecture And Structural Integrity In Myocardial Infarction., Annalara Garland Fischer

Electronic Theses and Dissertations

Expansion of the extracellular matrix (ECM), known as fibrosis, accompanies nearly all forms of cardiac disease; however, its most significant and complex manifestations arise following a myocardial infarction (MI). This process, principally led by fibroblasts, constitutes a necessary and adaptive response acutely to fill the void from cardiomyocyte necrosis following ischemic injury due to the heart’s lack of regenerative capacity. This acute response never fully resolves and contributes to ongoing collagen accumulation in non-infarcted regions, leading to diminished ventricular compliance, ongoing myocyte loss, and attrition in function—culminating in heart failure. Further, recent research demonstrates that concomitant with progressive increases in …

Exosomal Cannabidiol: A Promising Candidate For Targeted Oral Delivery Against Breast Cancer., Disha Nagesh Moholkar

Electronic Theses and Dissertations

Cancer therapies are limited by lack of specificity, selectivity and numerous adverse effects. Repurposing potential anticancer compounds with appropriate drug carriers can help overcome these drawbacks. In our present study, we address the major obstacle for cannabidiol (CBD): its low oral bioavailability, using exosomes. Exosomes (Exo) are promising non-toxic and biocompatible drug delivery vehicles Our project aims are to address the research gap by formulating exosomal cannabidiol (ExoCBD): a tumor-targeted oral delivery system for the treatment of breast cancer. The targeting approach relies on the overexpression of folate receptors at the tumor site by using folic acid functionalized exosomes (FA-Exo). …

Contested Spaces: Unhoused Black Men And Their Survival Within The Urban Landscape., Jonathan Riley Ellis

Electronic Theses and Dissertations

Thousands of unhoused Black men sleep, live and eat on the streets daily. Many lack the essential resources to survive through the elements. However, little is known about how unhoused Black men share space with the public, businesses, law enforcement and each other. Furthermore, little is known about how unhoused Black men access services once displacement has occurred. Drawing on participant observation and in-depth interviews, I examine how unhoused Black men navigate occupied urban spaces. I find that unhoused Black men regularly encounter contested spaces with businesses, the public, hospitals, and law enforcement. Additionally, unhoused Black men must navigate through …

Regulation And Mechanisms Of Ocular Dominance Plasticity At Cellular Resolution., Thomas Christopher Brown

Electronic Theses and Dissertations

Sensory systems throughout the brain require experience to aid in proper wiring during development. While forming, many sensory systems have periods of heightened sensitivity where alterations in the quality of experience can have a profound impact on cortical responses throughout life. These periods of heightened sensitivity have been coined critical periods. In the visual system of mice a critical period for ocular dominance has been well studied and defined between postnatal days nineteen and thirty-six. During this critical period, altering visual experience by suturing one eye closed called monocular deprivation (MD) shifts responses in cortex towards the non-deprived eye. Similar …

Health Professions Education And Critical Action Engagement: A Mixed Method Analysis., Leonda Richardson

Electronic Theses and Dissertations

Poorer health outcomes disproportionately impact racial/ethnically minoritized (e.g., Black Indigenous People of Color, or BIPOC) populations in the U.S. One plausible reason for the persistence of poorer health outcomes among this population is the teaching of racialized curricular content within academic health professions programs. This includes the absence of appropriate context through explicit socio-political curricular content (SPC) and critical pedagogy (i.e., social and structural determinants of health, history of racism in health care, social justice concepts; dialogue and reflective writing). Racialized curriculum is thought to initiate and/or exacerbate existing racial biases, cultural incompetence, and perpetuate dominant medical ideologies and myths …

Examination Of Model Minority Myth, Mentorship, University Environment, And Sense Of Belonging On The Well-Being Of Asian American Undergraduate And Graduate Students., Stephanie Chin, Stephanie Chin

Electronic Theses and Dissertations

Even though Asian Americans continue to demonstrate academic excellence and have the highest rates of completion in higher education, their psychological well-being and the factors impacting it are often overlooked due to the model minority myth (Poon et al., 2016; Mahalingham, 2013). Higher education research mainly focuses on academic outcomes (e.g., persistence and retention) and less so on psychological outcomes. This study explored and examined psychosociocultural factors, specifically internalization of the model minority myth stereotype, mentorship, university environment, and sense of belonging on psychological (eudaimonic) well-being, in order to provide a more holistic and contextualized perspective of Asian American students’ …

Molecular Mechanisms Of Exercise-Stimulated Resolution Of Inflammation And Its Dietary Dependence., Ernesto H. Pena Calderin

Electronic Theses and Dissertations

Diet-induced obesity and adipose tissue (AT) inflammation that ensues sets the stage for systemic metabolic inflammation, disrupted insulin signaling, and eventual type 2 diabetes (T2D) development. At the center of this pathology lies a disruption in endogenous inflammation resolution pathways characterized by an imbalance in lipid mediator production (greater abundance of pro-inflammatory to pro-resolving lipids). Additionally, obese states are characterized by adrenergic deficiency, especially in response to physical activity. Inflammatory processes have been experimentally mitigated by either the pharmacological inhibition of pro-inflammatory signals (i.e., Leukotriene B₄ (LTB₄) and its receptor BLT1, which establishes a potent chemotactic stimulus …

Epidural Stimulation For Urogenital Dysfunction In The Spinal Cord Injured Rat., Natasha Lorraine Wilkins

Electronic Theses and Dissertations

Spinal cord injury (SCI) is a devastating, life changing event that greatly impacts quality of life. SCI can have body-wide, multi-system consequences including dysfunction within the urogenital system. Challenges with the urinary system include urinary incontinence, urine retention, and detrusor-sphincter dyssynergia all of which require maintenance through the regular use of catheters. Sexual dysfunction in men, who comprise nearly 80% of the SCI population, includes erectile dysfunction, anejaculation, retrograde ejaculation, poor expulsive force during ejaculation, and poor sperm quality. The treatment for sexual function in SCI men is focused more on fertility through the collection of sperm for insemination procedures …

Associations Of Natural Vegetation In Relation To Colorectal Cancer Hotspots And Colorectal Cancer Survival., Johnnie Newton

Electronic Theses and Dissertations

Background: Across Kentucky, county-level geographic disparities in colorectal cancer (CRC) incidence and outcomes exist. Given the heterogeneity of lifestyle, socioeconomic (SES), and environmental factors within a county, more granular approaches should be used to identify local areas with a high CRC burden and identify the area-level factors that may contribute to geographic disparities. Studies reported that living in greener areas is associated with beneficial health outcomes, including lower mortality. Despite growing evidence that natural vegetation (greenness) exposure is associated with increased physical activity and obesity, two well-known CRC risk factors, epidemiological studies investigating the association of residential greenness exposure with …

Establishing A Mouse Model Of Cerebral/Cortical Visual Impairment., Dana K. Oakes

Electronic Theses and Dissertations

Cerebral/cortical visual impairment (CVI) is a disorder most often caused by perinatal hypoxic injury to the developing brain. CVI is the leading cause of childhood visual impairment in developed nations, encompassing deficits in many aspects of vision including visual acuity, contrast sensitivity, and object recognition. The pathophysiology of CVI is not well understood because no animal model currently exists to study this disorder. Because there is no animal model, the pathophysiology of CVI is poorly understood. Here, we developed a murine early postnatal hypoxic model of CVI by exposing mice to 9.5% O₂ at postnatal day (P)3 for a …

Housing Policy And Eviction: An Iterative Process., Oleksandra Maksymivna Belinova

Electronic Theses and Dissertations

Previously, eviction has been perceived as a legal problem rather than a social issue. Previous literature examines eviction as a social problem and the role of program administrators in policy implementation. Through a mixed-methods study of in-depth semi structured interviews and secondary descriptive analysis of eviction data, this study serves explores program administrators’ perspectives on housing policy and eviction practices and the impact these perspectives have on policy implementation and eviction prevention. The results indicate that program administrators view eviction as a legal phenomenon influenced by housing market dynamics with eviction prevention efforts limited by data collection and the lack …

Examining Associations Between Parental Meta-Emotion, Child Adhd Symptoms, And Socioemotional Impairments., Meaghan Flynn

Electronic Theses and Dissertations

Children with elevated attention-deficit/hyperactivity disorder (ADHD) symptoms are at increased risk for social and emotional problems compared to typically developing peers. Emerging research has suggested targeting parental emotion socialization practices to enhance socioemotional development among this population. Interventions have explored how targeting specific emotion socialization behaviors may promote emotional and social functioning for youth with ADHD; however, little research has evaluated how underlying parental attitudes may influence these behaviors and outcomes. Parental meta-emotion philosophy (PMEP) refers to an organized set of thoughts and beliefs on how parents view the purpose of emotions, expression of emotions, and how these beliefs are …

Risk Perception, Diabetes Risk Knowledge, And Fatalism In Adults At Risk For Type 2 Diabetes: A Self-Determination Theory Perspective., Cassandra M. Gonzalez

Electronic Theses and Dissertations

Introduction: Rising rates of diabetes in the U.S. indicate an urgent need to explore and understand factors that elucidate individual diabetes risk. Research of fatalism, the belief that events are predetermined, suggests that fatalistic beliefs influence, shape, and potentially determine health behavior and decision-making. The Theory of Self-Determination posits the importance of motivation and competence in health behavior outcomes. The present study aimed to expand fatalism research by examining associations among fatalism and diabetes-related beliefs and knowledge, including perceived risk and risk knowledge, within the Self-Determination theoretical framework. Methods: Participants were 130 adults aged 26 to 64 without diabetes at …

Coproduction Revisited: From Theory To Practice., Brenton Clarke Hereford

Electronic Theses and Dissertations

Coproduction, or the interaction of citizens with their public service provider, has been used in policy responses to a myriad of service delivery problems, especially policing. This dissertation uses a three-manuscript approach to revisit coproduction both as a theory and a practice. The first manuscript tracks the evolution of coproduction as a theory from three different disciplines: economics, urban theory, and public administration. In addressing the three disciplines, the manuscript explains what broadly united the coproduction literature and the differences that hindered the early development of the concept. It concludes with how the concept is used today, and how future …

Enhancing The Anticancer Effects Of Apiaceae Spice Phytochemicals., Jared Lee Scott

Electronic Theses and Dissertations

Breast cancer (BC) is a leading contributor to the death of women and is the most common type of cancer. Many chemotherapy drugs are developed from plants, and some plant extracts can exhibit significant anticancer activities while also having less toxic side effects. The Apiaceae plant family consists of several species that are used as culinarily spices which have demonstrated antioxidant, chemopreventive, and anticancer activities. The encapsulation of anticancer phytochemicals into naturally produced membrane-bound nanoparticles known as exosomes could improve their systemic distribution and efficacy. Exosomes are involved in cell-to-cell communication through the delivery of proteins, nucleic acids, and small …
