Associations Among Acculturative Stress, Body Ideal Internalization, Body Dissatisfaction And Disordered Eating Behaviors Among Cisgender Heterosexual And Lgbt People Of Color, Taryn Henning Jan 2024

Associations Among Acculturative Stress, Body Ideal Internalization, Body Dissatisfaction And Disordered Eating Behaviors Among Cisgender Heterosexual And Lgbt People Of Color, Taryn Henning

Theses and Dissertations

Research supports the relation between acculturative stress and disordered eating behaviors (DEBs) across racially and ethnically diverse groups of men and women. However, there is minimal research examining factors that further explain the relation between acculturative stress and DEBs. Also, this relation has not been evaluated in racially and ethnically diverse LGBT individuals. The current study aimed to address these gaps by examining the role of thin-, muscular-, and hourglass-ideal internalization and body dissatisfaction as mediators of the relation between acculturative stress and disordered eating behaviors among cisgender heterosexual Black, Latine, Asian American, Multiracial men and women and LGBT men …

Evaluating The Role Of Interoceptive Awareness In Insomnia And Across The Sleep Health Spectrum, Lara Lobrutto Jan 2024

Evaluating The Role Of Interoceptive Awareness In Insomnia And Across The Sleep Health Spectrum, Lara Lobrutto

Theses and Dissertations

Interoceptive awareness, characterized by a non-judgmental and trusting attitude towards body sensations, is an understudied construct that is implicated in sleep and health outcomes. Interoceptive awareness is cultivated via contemplative and mindfulness-based practices. Given that it may be utilized to reduce pre-sleep arousal, which is a key mechanism in insomnia, interoceptive awareness is posited to be a protective factor for sleep health. A cross-sectional study was conducted among undergraduate university students (N = 420) in the Mid-Atlantic region of the United States to assess the association between interoceptive awareness and sleep outcomes. Participants received a survey link and completed …


Analyzing The Role Of Slc25a32 In Hepatocellular Carcinoma, Mimansha Shah Jan 2024

Analyzing The Role Of Slc25a32 In Hepatocellular Carcinoma, Mimansha Shah

Theses and Dissertations

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and a leading cause of cancer-related deaths worldwide. Despite advances in understanding its molecular pathogenesis, treatment options for HCC remain limited, highlighting the need for identifying novel therapeutic targets. This study investigates the role of SLC25A32, a mitochondrial transporter gene located on chromosome 8q22.3, in HCC progression. SLC25A32 is involved in the transport of tetrahydrofolate (THF) and flavin adenine dinucleotide (FAD) into mitochondria, playing a crucial role in one-carbon metabolism and redox balance. Using CRISPR/Cas9 technology, we generated potential SLC25A32 knockout clones in the HCC cell line Huh-7. Quantitative PCR …


The Effect Of 17Β Estradiol On Local Production Of Active Vitamin D3 Metabolites In Laryngeal Squamous Cell Carcinoma, Tillat Batool Jan 2024

The Effect Of 17Β Estradiol On Local Production Of Active Vitamin D3 Metabolites In Laryngeal Squamous Cell Carcinoma, Tillat Batool

Theses and Dissertations

Laryngeal squamous cell carcinoma (LSCC) has garnered attention as a sex-hormone-dependent cancer with notable responsiveness to 17β-estradiol (E2), in which it’s tumorigenesis can be mediated through estrogen receptors (ER). The ESR1 gene encodes for the classical full-length ERα66, as well as splice variants ERα36 and ERα46. Previous studies have shown that an active vitamin D3metabolite, 24R,25(OH)2D3. has pro-tumorigenic or anti-tumorigenic responses in LSCC cells with different ER profiles, and that the tumor cells have the capability of localized production of vitamin D metabolites at the cellular level when treated with 25(OH)D3-d6 …

How Ebony Transcends In The Ivory Tower: Unveiling Transformational Black Women Forging Leadership Paths In Historically White Institutions, Lauren N. Jackson

Theses and Dissertations

Considerable literature has amplified the perceived challenges and deficits of Black women as they advance in their careers within historically white institutions (HWI). As a result, there is a notable absence of anti-deficit explorations of the inherent abilities and strengths that contribute to Black women’s professional mobility. Grounded in anti-deficit achievement framework and Black feminist leadership, this study aimed to illuminate the assets and factors that influence the professional ascension of seven, current/former senior-level Black women in a HWI within the Southeastern region of the U.S. By adopting a qualitative, phenomenological framework, this study provides in-depth insights into the participants’ …


Sphingosine Kinase 2 Depletion Dysregulates Hepatic Redox Metabolism And Enhances Inflammation In Early Metabolic Dysfunction-Associated Steatohepatitis (Mash), Kaitlyn Georgene Jackson Jan 2024

Sphingosine Kinase 2 Depletion Dysregulates Hepatic Redox Metabolism And Enhances Inflammation In Early Metabolic Dysfunction-Associated Steatohepatitis (Mash), Kaitlyn Georgene Jackson

Theses and Dissertations

Metabolic dysfunction-associated steatotic liver disease (MASLD) currently affects one in three people worldwide; its prevalence is growing alongside other cardiometabolic disorders. Aberrations to redox and sphingolipid metabolism contribute to MASLD pathologic progression. Sphingosine-1-phosphate (S1P) is an active lipid, meaning that S1P participates in biochemical processes within the cell. S1P is generated by two distinct isoenzymes, sphingosine kinase (SphK)1 and SphK2. The localization of the SphK enzyme dictates S1P function. While cytosolic SphK1-generated S1P is well-characterized, nuclear and mitochondrial SphK2-generated S1P is less known. Moreover, SphK2 depletion effects on cellular redox processes and inflammation are not well-defined.

This study defines the …

Longitudinal Analysis Of Maternal Depression, Physical Work Demand, And Working Hours Before, During, And After Pregnancy On Offspring Blood Pressure Trajectories, Medhin Tsegaye Haile

Theses and Dissertations

Overall Abstract

Background: Pediatric high blood pressure (BP) is a growing global concern, with 1 in 7 adolescents in the U.S. experiencing elevated BP or hypertension. Maternal lifestyle factors, including depressive symptoms, physically demanding work, and work hours during pregnancy, may influence offspring BP trajectories. However, prior studies often focus on single time points or specific age groups, limiting understanding of long-term effects. This study investigates the associations between maternal depressive symptoms, physically demanding work-related factors, and work hours before, during, and after pregnancy with offspring systolic blood pressure (SBP) trajectories from early childhood to adolescence.

Methods: We utilized …


Observed Parent And Child Differences In Black Mothers Of Children With And Without Attention-Deficit/Hyperactivity Disorder, Sydney E. Padgett Jan 2024

Observed Parent And Child Differences In Black Mothers Of Children With And Without Attention-Deficit/Hyperactivity Disorder, Sydney E. Padgett

Theses and Dissertations

Attention-Deficit/Hyperactivity Disorder (ADHD) is childhood's most common neuro- developmental disorder, mainly distinguished by a pattern of inattention, hyperactivity and/or impulsivity. Compared to the plethora of research on White children with ADHD, the research on Black children with ADHD is limited. Looking more closely at the functions related to parenting children with ADHD, there is even less information known on the interactions between Black children and their parents compared to White children and their parents. The primary aim of the thesis study was to compare observed parenting and child behaviors between Black mother/child dyads of children with and without ADHD. This …


Cellular Metabolism Is A Viable Therapeutic Target For Radiation-Induced Pulmonary Fibrosis, Josly Pierre-Louis Odoom Jan 2024

Cellular Metabolism Is A Viable Therapeutic Target For Radiation-Induced Pulmonary Fibrosis, Josly Pierre-Louis Odoom

Theses and Dissertations

Herein, we provide evidence for cellular metabolic reprogramming as a driver of radiation-induced pulmonary fibrosis (RIPF). We are the first to identify a distinct metabolic signature for RIPF in a cohort of patients with radiographic sequela. We also used a RIPF mouse model to detect the metabolic pathways that enrich during pathogenesis. Our previous work highlighted the importance of lactate, a derivative of the glycolysis end-product pyruvate. Consequently, we took a special interest in the effects of radiation on the glycolysis pathway. We learned that radiation accelerates and reprograms glycolysis to an anabolic state in a pyruvate kinase M2 (PKM2)-dependent …


A Multilevel, Mixed Methods Examination Of Food Insecurity, Housing Instability, And Cardiovascular Health, Sarah Collins Jan 2024

A Multilevel, Mixed Methods Examination Of Food Insecurity, Housing Instability, And Cardiovascular Health, Sarah Collins

Theses and Dissertations

BACKGROUND

Housing instability and food access are both robust risk factors for cardiovascular disease (CVD), which claims more lives annually in the U.S. than cancer and chronic lung disease combined. We hypothesized that experiencing both housing instability and food insecurity would have an additive effect on CVD risk, resulting in elevated blood pressure (BP) and perceived stress among young adults (YA).

METHODS

This research examined the relationships between food insecurity, housing instability, stress, and cardiovascular disease risk through three aims. First, multivariate linear regression was used to assess associations among YA, focusing on eviction, food insecurity, and blood pressure. Second, …


The Role Of Hdac6 In Periodontal Inflammation, Hannah S. Lohner Jan 2024

The Role Of Hdac6 In Periodontal Inflammation, Hannah S. Lohner

Theses and Dissertations

Periodontal disease is a polymicrobial infection-induced chronic inflammatory disease and results in irreversible tissue damage and bone loss. While bacteria play a large role in the initiation of this disease, excessive and prolonged inflammatory immune responses are fundamental for its progression, making host directed therapy (HDT) a possible and potentially valuable treatment. Histone Deacetylase 6 (HDAC6) is an enzyme that removes acetyl groups from both histone and non-histone proteins, giving it a potential role in regulating inflammation initiated by pathogenic oral bacteria. Previous studies indicated that HDACs act as a bivalent regulator in inflammatory responses; however, the role that HDAC6 …


Correlates Of Coffee And Energy Drink Use Among Individuals With Severe Alcohol Use Disorder, Enkelejda Ngjelina Jan 2024

Correlates Of Coffee And Energy Drink Use Among Individuals With Severe Alcohol Use Disorder, Enkelejda Ngjelina

Theses and Dissertations

Research on caffeine consumption among college students and young adults has primarily focused on caffeinated energy drinks (EDs) and their combination with alcohol, demonstrating a strong association with heavy and problematic alcohol use. However, little attention has been directed toward older adults. Furthermore, studies have shown that regular ED consumers are more likely to meet the criteria for alcohol dependence compared to their peers. Despite this association, little is known about ED consumption among individuals with Alcohol Use Disorder (AUD), particularly those undergoing treatment, and even less is understood about other caffeine sources such as coffee. This study aimed to …


Role Of Human Intermediate Form Prl Receptor I-Tail In The Pathogenesis Of Breast Cancer, Shanwei Shen Jan 2024

Role Of Human Intermediate Form Prl Receptor I-Tail In The Pathogenesis Of Breast Cancer, Shanwei Shen

Theses and Dissertations

Breast cancer continues to be the second most common cancer in women in the United States. The neuroendocrine hormone human prolactin (hPRL) plays an important role in normal mammary gland development and growth, stimulating normal breast tissue proliferation and differentiation. Considerable evidence has shown that hPRL is involved in the malignant transformation of human breast tissue. hPRL enhances viability, invasiveness, and proliferation of breast cancer cells in vitro. Evidence from epidemiologic and genetic studies also implicates role of hPRL in the pathogenesis of breast cancer. Its cognate receptor the human prolactin receptor (hPRLr) is required for the action of hPRL. …


Repeated-Measures Latent Profile Analyses Of Intervention Fidelity To A Teacher-Delivered Intervention Program For Children At Elevated Risk For Emotional And Behavioral Disorders, Katrina A. Markowicz Jan 2024

Repeated-Measures Latent Profile Analyses Of Intervention Fidelity To A Teacher-Delivered Intervention Program For Children At Elevated Risk For Emotional And Behavioral Disorders, Katrina A. Markowicz

Theses and Dissertations

Teachers have difficulty delivering Tier-2 intervention programs for preschoolers at elevated risk for socioemotional and behavioral disorders with high intervention fidelity (Durlak, 2010; Sutherland et al., 2018). Several proximal factors that impact program fidelity have been identified, which may undermine program effects (Domitrovich et al., 2008; McLeod et al., 2022; Sutherland et al., 2018). Therefore, researchers have identified strategies, such as practice-based coaching, to improve intervention fidelity and support teachers (Hemmeter et al., 2015; Synder et al., 2015). Most of the field's knowledge of these topics is limited to variable-centered approaches (Fettig et al., 2022; Low et al., 2016). However, …


Acute Effects Of An Oral Nicotine Pouch In People Who Use Smokeless Tobacco, Alisha Eversole Jan 2024

Acute Effects Of An Oral Nicotine Pouch In People Who Use Smokeless Tobacco, Alisha Eversole

Theses and Dissertations

People who use smokeless tobacco (SLT) are exposed to a variety of carcinogenic toxicants, yet, despite health risks, nearly 6 million people in the US use SLT. SLT contains and delivers nicotine, a psychostimulant that causes dependence and hinders cessation efforts. An orally-administered nicotine pouch marketed as “tobacco-free” recently has become available for purchase in the US. However, there are very few non-industry-sponsored studies regarding the effects of these oral nicotine pouches.

The current study used clinical laboratory methods to determine the acute effects of an oral nicotine pouch in people who use SLT. Participants completed four sessions (within subjects, …


Assessing Providers’ Readiness To Integrate Mat Services In A Primary Care Setting, Carmen Ingram-Thorpe Jan 2024

Assessing Providers’ Readiness To Integrate Mat Services In A Primary Care Setting, Carmen Ingram-Thorpe

Theses and Dissertations

Opioid use disorder is a growing concern in the United States. Despite medication-assisted treatment (MAT) being a more effective treatment option than behavioral treatment alone, primary care providers’ rate of adoption and utilization of MAT has not matched the demand of the opioid crisis. The largest barrier facing our local community is the availability of organizations and providers that can and will actually provide MAT services. The purpose of this study was to identify factors that impact primary care providers’ readiness to treat individuals with opioid use disorder (OUD) using MAT. This study used the ADKAR model as framework, which …

Theses and Dissertations

Artificial Intelligence's (AI) rise has created value for organizations and society, prompting scholars to study its spread across many areas. However, the impact of AI adoption on governmental organizations still needs to be explored. Governmental entities face unique challenges distinct from private organizations, and existing research often focuses on the perspectives of AI experts or senior management, neglecting the insights of lower-level employees who will use the system daily.

This study investigates the multifaceted factors influencing the intention to adopt AI tools within a governmental auditing bureau in Saudi Arabia. To the best of our knowledge, no previous study has …


Memory Impairments Due To Binge Ethanol Are Impacted By Age And Sex, Maria Alexis M. Bent Jan 2024

Memory Impairments Due To Binge Ethanol Are Impacted By Age And Sex, Maria Alexis M. Bent

Theses and Dissertations

Ethanol is the most consumed drug among adolescents, which can cause long-term effects on memory and changes in gene and protein expression. While both adolescents and adults engage in binge drinking, the neurological and behavioral effects differ, with adolescents showing fewer adverse physiological effects but greater memory deficits than adults. Sex differences related to ethanol occur with women showing higher BEC than men and similar cognitive deficits despite fewer years of ethanol consumption. During adolescence the mPFC and dHPC undergo maturation development with both brain regions playing a role in spatial and recognition memory. Proteins critically involved in memory and …


Latent Profiles Of Child Coping And Perception Of Experience Processes To Predict Long-Term Symptoms Of Depression, Intrusive Grief, And Suicidality Outcomes In Parentally Bereaved Children, Rebecca Hoppe Jan 2024

Latent Profiles Of Child Coping And Perception Of Experience Processes To Predict Long-Term Symptoms Of Depression, Intrusive Grief, And Suicidality Outcomes In Parentally Bereaved Children, Rebecca Hoppe

Theses and Dissertations

Childhood bereavement is a significant public health issue and the most distressing form of childhood trauma. The death of a parent can disrupt the course of a children's development and potentially predispose them to enduring adverse mental health outcomes, such as depression, intrusive grief, and suicidality. Recognizing grief as a dynamic process, theories have suggested that children’s unique coping and perceptions of experience can contribute to variations in individual adaptations to the death and the onset of mental health problems. The goals of this study were to (a) use latent profile analysis to empirically group recently bereaved children into distinct …


Exploring The Role Of Senescence In Disuse-Induced Bone Loss And Therapeutic Strategies For Prevention, Steven J. Meas Jan 2024

Exploring The Role Of Senescence In Disuse-Induced Bone Loss And Therapeutic Strategies For Prevention, Steven J. Meas

Theses and Dissertations

Both age-related and disuse-related bone loss result in decreases in bone mineral density, cortical thickness, and trabecular thickness and connectivity. Disuse induces physiological changes in bone similar to those seen with aging. This study compared age- and disuse-related bone loss using C57BL/6J mice of various ages that were hind-limb unloaded (HLU). In male and female mice, HLU induced a bone phenotype between those of 6-month-old and 22-month-old control mice. Gene analysis suggested that HLU leads to mitochondrial dysfunction, while aging primarily downregulates cell cycle processes. Although, the specific response to HLU appeared to be dependent on age. The study identified …


A Qualitative Analysis Of Section 1983 Filings By Incarcerated Plaintiffs, Hollie Macdonald Jan 2024

A Qualitative Analysis Of Section 1983 Filings By Incarcerated Plaintiffs, Hollie Macdonald

Theses and Dissertations

The onset of the COVID-19 pandemic was a “watershed moment" in human history, transcending its role as a mere health crisis to reveal deeper fissures within societies. The present retrospective longitudinal study examined COVID-19 as an “era” of complexity utilizing it as an intermediate construct that delineates “pre-COVID” and “post-COVID.” In order to understand the impact of the COVID-19 era, the design of the study and hypotheses stem from an assumption of the interconnectedness of issues related to health, social justice, racial justice, politics, and information dissemination.

This study utilized both manifest and latent content analysis to explore the most …


The Relationship Between Outcomes Associated With Patient Blood Management Programs And Transfusion Safety Officers, Gary Morral Jan 2024

The Relationship Between Outcomes Associated With Patient Blood Management Programs And Transfusion Safety Officers, Gary Morral

Theses and Dissertations

BACKGROUND: Patient Blood Management (PBM) has become the standard of care for transfusion services in hospitals. Transfusion Safety Officers (TSOs) have been identified by some as being a crucial part of a successful PBM program; however, no studies have been done to show their effectiveness, or if there is even a relationship between having a TSO and outcomes associated with PBM programs. The purpose of this study was to describe and test the relationship between having a TSO and six outcomes associated with PBM programs including blood product wastage (red blood cells, plasma, and platelets), hospital lengths of stay, rates …


Exploring Emerging Adults' Consideration Of Future Cancer Risk Reduction: Opportunity For Shifting Prevention Paradigms?, Jacqueline Knight Wilt Jan 2024

Exploring Emerging Adults' Consideration Of Future Cancer Risk Reduction: Opportunity For Shifting Prevention Paradigms?, Jacqueline Knight Wilt

Theses and Dissertations

Background
Early onset colorectal cancer (EOCRC) among individuals younger than age-based population prevention screening guidelines has been linked to lifestyle-related risk factors. Emerging adulthood (18-25 years) is when elevated autonomy can alter health behaviors with implications for future health. Greater consideration of future consequences for behavior predicts several lifestyle health behaviors. Future consideration is sensitive to resource availability, and thus may differ between students who are first-generation and/or from low-income households (FGLI) compared to Non-FGLI. This dissertation study aimed to (1) characterize college students’ consideration of future cancer risk (CFC-Cancer), perceived colorectal cancer (CRC) risk and associations with EOCRC risk …


Investigation Of Brain Function And Structural Development As Risk Factors Of Suicidal Thoughts And Behaviors, Yi Zhou Jan 2024

Investigation Of Brain Function And Structural Development As Risk Factors Of Suicidal Thoughts And Behaviors, Yi Zhou

Theses and Dissertations

Background: Identifying risk factors for suicidal thoughts and behaviors, especially causal ones, will be imperative to improving screening and treatment interventions. To identify replicable brain-based risk factors, there is increasing evidence indicating the need for large sample sizes, in the hundreds to thousands, in order to achieve a sufficient level of statistical power to detect them. Furthermore, longitudinal studies of brain and behavioral factors will be essential to understanding how suicide develops, especially the transition from suicide ideation to attempt. While experimental studies may not be feasible or ethical, genetically informed methods for testing evidence for causation are an alternative …

Enhancing Chemotherapeutic Efficacy Of Doxorubicin Through Combination Therapy With Rapamycin And Sildenafil, While Providing Cardioprotection In Breast Cancer Models, Rebecca Mathew

Theses and Dissertations

Doxorubicin (DOX) is a common chemo-drug for breast cancer, but it causes severe cardiotoxicity. This study explores combining Sildenafil (Sild) and Rapamycin (Rapa), which inhibit phosphodiesterase-5 (PDE5) and mTOR, respectively, to boost DOX’s anticancer, but provide cardioprotection. Triple negative human (MDA-MB-231) and murine (4T1) breast cancer cells were treated with DOX (1 µM) with/without Rapa (100 nM) and Sild (10 µM) for 24-72 hours to analyze cell death, cell viability assays and protein expression. Human epidermal growth factor receptor 2-positive breast cancer (SKBr3) spheroids were treated with the same concentrations of DOX and/or AG825 (5µM) with/without Rapa and/or Sild for …


Behavioral Effects Of Adolescent Social Isolation Stress And/Or Binge Drinking And The Role Of The Vhip --> Mpfc Circuit, Jyoti Lodha Jan 2024

Behavioral Effects Of Adolescent Social Isolation Stress And/Or Binge Drinking And The Role Of The Vhip --> Mpfc Circuit, Jyoti Lodha

Theses and Dissertations

Adolescence is characterized by heightened social interaction and risk-taking behavior. Disruptions to cortical development by binge ethanol or social isolation can lead to attention, social, and cognitive deficits later in life, and increase risk for alcohol use disorders. During adolescence, proper development of a monosynaptic connection from the ventral hippocampus (vHip) to the medial prefrontal cortex (mPFC) is critical to proper social and working memory. We ask whether these factors affect neurobiological factors such as gene expression and the role of the vHipmPFC circuit in these behaviors. Social stress was modeled by social isolation (aSI) during adolescence. We expect aSI …
