Sense Of Belonging As Behaviorist Construct: “Doing Belonging” And Its Application For College Students With Disabilities, Chris Parthemos Phd

Theses and Dissertations

Sense of Belonging has been widely linked to academic performance, retention and persistence for college students. Students with disabilities are less likely to enroll than peers, and are more likely to drop out. Similar to other historically-marginalized groups, these students report lower sense of belonging than peers. Research with this population suggests that they may be seeking ways of building community and belonging at their universities which are self-driven. This notion of “doing belonging”, as it is described in the sociological literature, appears at first glance to be compatible with behaviorist approaches to student support. Although not without controversy, behavior …

Formation Of Vasculogenic Mimicry: Role Of Melanoma Differentiation Associated Gene-9 In Human Melanoma, Jinkal Shah

Theses and Dissertations

Malignant melanoma (MM) is the most aggressive skin cancer and the most frequent skin disorder in Caucasians. MM is associated with aggressive and progressive disease states, leading to major cancer-related morbidity and mortality. Recent investigations identify an alternative pathway -vasculogenic mimicry (VM), which is considered a cancer hallmark that can independently facilitate tumor neovascularization by the formation of fluid-conducting and vascular endothelial cells. MM cells undergoing VM can dedifferentiate into numerous cellular phenotypes and acquire endothelial-like features, resulting in the formation of the de novo matrix-rich vascular-like networks, such as plasma and red blood cells. The co-generation of endothelial cells, …

Incorporating A Developmental Perspective Into Gene Identification Models For Alcohol Use Behaviors, Nathaniel S. Thomas

Theses and Dissertations

Frequent alcohol use can lead to alcohol use disorder, which accounts for three million deaths and over 133 million life years lost to disability and death worldwide per year.

Alcohol use behaviors are also under genetic influence. Genome-wide association represents the state-of-the-science statistical methodology for identifying genes associated with alcohol use outcomes. However, contemporary genome-wide association study (GWAS) methods typically do not account for variability in genetic effects throughout development. In this project, I applied novel multivariate genomic methods to combine …

Exploring The Effect Of Early Motor Delay And Physical Therapy Interventions On The Parent-Child Relationship, Rebecca Molinini

Theses and Dissertations

Emotional availability (EA) or the ability of the parent-child dyad to engage emotionally and partake in congruent and mutually enjoyable interactions, is essential for familial health and well-being. EA is considered the “connective tissue” of healthy parent-child relationships and is associated with secure attachment, maternal mental health, and children’s adaptive development. Most evidence supporting the integral role of EA on healthy outcomes is supported by typically developing populations in which adults present with a social or biological risk factor such as experiencing past traumas of adversities with mental health. In line with the transactional model of development, children are equal …

Examining Psychosocial Factors Of Chronic Disease Control To Improve Outcomes For Patients With Multiple Chronic Conditions, Kristen O'Loughlin

Theses and Dissertations

Psychosocial needs are associated with worse health outcomes for patients with multiple chronic conditions (MCC). The Biopsychosocial Model provides a framework for conceptualizing the influence that psychosocial factors have on the management of disease. To date, research has primarily focused on examining the relation between psychosocial factors and chronic disease onset. Therefore, the temporal relation between psychosocial factors and disease management remains poorly understood. The current study aimed to 1) describe patients’ psychosocial needs and their prioritization, 2) examine reciprocal relations between anxious symptoms, depressive symptoms, social needs, and MCC management, and 3) qualitatively explore patient definitions of health in …

Age-Associated Collagen Crosslinking And Its Role In Skeletal Muscle Regeneration, Lucas C. Olson

Theses and Dissertations

Advanced glycation end-products (AGEs) non-enzymatically accumulate on skeletal muscle collagen in old age via the Maillard reaction, causing an increase in intramuscular collagen and a stiffening of the muscle’s microenvironment. AGEs abrogate muscle regeneration through stiffening the muscle stem cell (MuSC) microenvironment and by binding to the receptor for advanced glycation end products (RAGE). Stiffer substrates promote MuSC proliferation at the expense of differentiation, and soluble AGEs are known to abrogate myogenic differentiation. Previously our group has demonstrated that decellularized muscle matrix (DMM), a type of extracellular matrix (ECM) scaffold extracted from skeletal muscle, encourages regeneration in a challenging rat …

Exploring The Relationship Between The Epigenome And Metabolism In Mycn-Amplified Neuroblastoma, Krista M. Dalton

Theses and Dissertations

High risk neuroblastoma (NB) is responsible for nearly 15% of all cancer related deaths in the pediatric population. The transcription factor MYCN is the most studied oncogene in NB, automatically conferring high-risk and has been found to be difficult to target. One way that MYCN amplification in NB functions to support tumorigenicity is through altered metabolism, satisfying the demand for rapid proliferation by increasing the nutrient flux through biosynthetic pathways. We performed an unbiased screen on select metabolic targeted therapy combinations and correlated sensitivity with over 20 subsets of cancer. We found that MYCN-amplified NB is hypersensitive to the …
