The Post-Closet Home: Queer Domesticity, Enclosure, And Queer Southern Gothicism In Lee Mandelo's "Summer Sons", Andrew Dylan Dampier
The Post-Closet Home: Queer Domesticity, Enclosure, And Queer Southern Gothicism In Lee Mandelo's "Summer Sons", Andrew Dylan Dampier
Master's Theses
In current discussions of queer theory, terms such as “post-gay” leave room for misrepresentation. The premise behind this term serves a primarily cisgenderheterosexual agenda by promising the assimilation of queer individuals into the dominant society. For this reason, I prefer to align the term “post-closet” with the queer person’s journey towards, and past, such societal barriers while maintaining the significance of foundational queer theories. In his novel Summer Sons, Lee Mandelo depicts Andrew Blur’s journey through the grief-ridden confines of the closet as he seeks a new identity following the death of his best friend. Mandelo accomplishes this by juxtaposing …

Regulation Of Sterile Inflammatory Responses By Mitochondria-Associated Proteins, Meghana Venkatesan
Regulation Of Sterile Inflammatory Responses By Mitochondria-Associated Proteins, Meghana Venkatesan
Master's Theses
Inflammation is an important defense mechanism through which cells respond to pathogenic insults and damage/stress signals. Immune cells mediate extracellular inflammatory responses by synthesizing and releasing small proteins called cytokines, which play critical roles in modulating these responses. Specifically, key pro-inflammatory cytokines such as IL-1beta are released upon the assembly and activation of a multi-protein intracellular complex called the inflammasome, the most well-studied of which is the NLRP3 inflammasome. Several proteins have been identified as important regulators of cellular stress responses, including vacuole membrane protein 1 (VMP1). The present research shows that VMP1-depleted cells exhibit exacerbated cellular inflammation and are …
