Examining Allostatic Load As A Biological Mechanism Linking Childhood Adversity And Pediatric Pain, Angela Pascale

Theses and Dissertations

Despite a strong literature base relating childhood adversity to pain, the biological mechanisms underlying these associations remain unclear. Theoretical and preliminary empirical evidence supports allostatic load as a potential biological mechanism, though prior studies investigating associations between childhood adversity and elevated allostatic load and/or between elevated allostatic load and poorer pain outcomes have primarily focused on adult populations and individual allostatic load indicators rather than a comprehensive index. Thus, the current study built upon prior literature by testing longitudinal relationships between childhood adversity and multiple biological indicators spanning across physiological systems (i.e., comprehensive allostatic load index) and pediatric pain outcomes …

Molecular Mechanisms Of Prdm16 As A Tumor Suppressor In Pancreatic Ductal Adenocarcinoma, Eric Hurwitz

Theses and Dissertations

The transcription factor Prdm16 functions as a potent suppressor of transforming growth factor-beta (TGF-b) signaling, whose inactivation is deemed essential to the progression of pancreatic ductal adenocarcinoma (PDAC). Using the Kras^G12D-based mouse model of human PDAC, we surprisingly found that ablating Prdm16 did not block but instead accelerated PDAC formation and progression, suggesting that Prdm16 might function as a tumor suppressor in this malignancy. Subsequent genetic experiments showed that ablating Prdm16 along with Smad4 resulted in a shift from a well-differentiated and confined neoplasm to a highly aggressive and metastatic disease, which was associated with a striking deviation …

Assessing The Relationships Between Direct And Vicarious Exposure To Healthcare Discrimination And Erasure, Mistrust In Healthcare, And The Healthcare Utilization Behaviors Among Transgender And Gender Independent Individuals, Kyle L. Mason

Theses and Dissertations

Healthcare inaccessibility through direct exposure (i.e., personal) to myriad forms of gender identity-related discrimination and erasure among the Transgender and Gender Independent (TGI) population has been documented by prior studies. The myriad barriers that individuals who embody TGI identities encounter to accessing healthcare are associated with the underutilization of healthcare, which may further exacerbate the health disparities that exist between this population and cisgender individuals in the United States (U.S.). Although the impacts of the harm that direct exposure to healthcare discrimination and erasure may have on TGI individuals are known, their exposure to such harm vicariously (i.e., through observation …

Soil Bacteria Composition In Conservation Reserve Program Grasslands Of The Great Plains, Lydia M. Kantonen

Theses and Dissertations

The Conservation Reserve Program (CRP) is a grassland restoration program that allows landowners to remove degraded land from crop production, seed it with a perennial seed mixture, and leave it fallow for the remainder of the contract, which usually ranges from 10-15 years. While some ecosystem functions quickly improve upon CRP enrollment, soil organic carbon is slow to return to pre-agricultural levels. One explanation is that particulate organic matter left by litter takes several years to degrade even with a full bacteria community. Alternatively, it is possible that different chemical components of organic matter require different bacteria communities for full …
