The Superhero Gothic: The Montrous Hero To The Heroic Monster In The Twentieth Century., John Darowski

Electronic Theses and Dissertations

The influence of Gothic literature and its adaptations on the superhero genre has been profound. Both genres have an ideological project of the restoration of normalcy and order after disruption and disorder, thereby reinforcing cultural norms. However, their themes and methodologies are diametrically opposed. The Gothic is an exploration of the negative aesthetics of terror and horror, which reveal human weaknesses. The superhero is a power fantasy that celebrates justice and morality. A synthesis of the two creates a paradox: the monstrous hero—a Hoppen stand hero who takes on the attributes of a monster—who evolves into the heroic monster—a monster …

The Examination Of Intratumoral Compression As A Mechanobiological Driver Of Glioblastoma Progression., Allison Mckenzie Johnson

Electronic Theses and Dissertations

Glioblastoma diagnosis has one of the lowest average life expectancies at only 14 months. Recurrent tumor formation and progression despite aggressive chemotherapy and radiation significantly contributes to the poor prognosis. Recurrence is likely due to mesenchymal cells breaking off from the primary tumor, infiltrating the parenchyma to establish secondary tumors. Mesenchymal cells initially undergo an epithelial to mesenchymal transition, characterized by a loss of cell-cell adhesion, increased migration and increased proliferation. While this transition can be chemically induced, there is a gap of understanding surrounding physical activation of this pathway. The tumor microenvironment is mechanically active with the cells responding …

Macrophage Polarization And Colorectal Cancer Immune Checkpoint Protein Expression., Anne Macleod

Electronic Theses and Dissertations

The majority of patients with colorectal cancer do not respond to treatment with immunotherapy. Immunotherapy requires the expression of cell surface immune checkpoint proteins (e.g. PDL1) to exert its effect. Most (>85%) of colorectal cancers do not express these proteins and this contributes in part to the poor prognosis and survival in patients with advanced disease. The patients in which immunotherapy is a potential treatment option, are a genetic subtype known as mismatch repair deficient, and have demonstrated an excellent response to anti-PD-1/PDL1 immunotherapy. A key feature of mismatch repair deficient (MMRd) cancers is their immune cell rich tumor …
