Faculty, Staff and Student Publications

Nexavant was reported as an alternative to the TLR3 agonist of Poly(I:C) and its derivatives. The physicochemical properties, signaling pathways, anti-cancer effects, and mechanisms of Nexavant were investigated. The distinctive characteristics of Nexavant compared to that of Poly(I:C) were demonstrated by precise quantification, enhanced thermostability, and increased resistance to RNase A. Unlike Poly(I:C), which activates TLR3, RIG-I, and MDA5, Nexavant stimulates signaling through TLR3 and RIG-I but not through MDA5. Compared to Poly(I:C), an intratumoral Nexavant treatment led to a unique immune response, immune cell infiltration, and suppression of tumor growth in various animal cancer models. Nexavant therapy outperformed anti-PD-1 …

Ewsr1::Atf1 Orchestrates The Clear Cell Sarcoma Transcriptome In Human Tumors And A Mouse Genetic Model, Benjamin B Ozenberger, Li Li, Emily R Wilson, Alexander J Lazar, Jared J Barrott, Kevin B Jones

Faculty, Staff and Student Publications

Clear cell sarcoma (CCS) is a rare, aggressive malignancy that most frequently arises in the soft tissues of the extremities. It is defined and driven by expression of one member of a family of related translocation-generated fusion oncogenes, the most common of which is EWSR1::ATF1. The EWSR1::ATF1 fusion oncoprotein reprograms transcription. However, the binding distribution of EWSR1::ATF1 across the genome and its target genes remain unclear. Here, we interrogated the genomic distribution of V5-tagged EWSR1::ATF1 in tumors it had induced upon expression in mice that also recapitulated the transcriptome of human CCS. ChIP-sequencing of V5-EWSR1::ATF1 identified previously unreported motifs …

In What Ways Does The Proliferation Of Neoliberal Reform Initiatives (Nclb) Perpetuate The Marginalization Of Students In Urban Inner-City Schools? A Critical Discourse Analysis On Supplemental Education Services (Ses) And Adequate Yearly Progress (Ayp) In Izones Schools Cohorts 1 And 2., Rodney Jarrell Rowan

Electronic Theses and Dissertations Archive

The No Child Left Behind Act (NCLB) has been cited as the pinnacle of the high-stakes accountability movement. NCLB required all students (subgroups) in public education to achieve 100% proficiency in reading and mathematics by 2014 on individual state-mandated standardized tests. The federal government authorized each state the right to define the measures that constituted proficiency (USDOE, 2002, NCLB ACT, Section 1111(2) B). This study revealed how the proliferation of neoliberal reform initiatives perpetuates the marginalization of urban inner-city school students. Under the guise of student subgroups, NCLB labeled students by race and ethnicity, academic status, and social identity. The …

Advancing Air Filtration Analysis: A Comprehensive Approach To Particle Loading Models, Gentry Nathaniel Berry

Theses and Dissertations

Fibrous air filters are commonly used to capture airborne particles due to their potential for a relatively high capture efficiency and low airflow resistance. Their performance characteristics make them ideal candidates in many instances, spanning a wide range from residential to sensitive industrial applications. However, as more particles are captured, the performance of the filter will evolve. This evolution of performance typically manifests as a higher capture efficiency and higher airflow resistance resulting from the additional particulate deposits. The prediction of fibrous filter performance has been the focus of research for many decades, resulting in numerous analytical, numerical, and empirical …

Advancing Salamander Conservation Efforts In Zoos And Aquaria Through Assisted Reproductive Technologies (Art), Devin Marie Chen

Theses and Dissertations

Salamanders are one of the most at-risk taxa in the world due to habitat destruction, pollution, climate change, invasive diseases, and more. This has led to a need for conservation breeding programs that are often associated with zoos and aquaria. Salamanders can be difficult to breed in captivity, though, due to their dependence on specific environmental cues and other unknown factors that stimulate sperm and egg production. To overcome these challenges, assisted reproductive technologies (ART) such as exogenous hormone administration, sperm cryopreservation, and in-vitro fertilization have been developed to increase offspring propagation and maintain genetic diversity. If genetically robust populations …

We Built This Country For Free – Using A Phenomenological Approach For (Re) Imagining Mississippi Black Small-Scale Farmers, Destiny Denise Crockett

Theses and Dissertations

By the early 20th century, in 1920, Black farmers owned 14% of US farmland. Today, in the 21st century, Black farmers own less than 2% of US farmland. The demise of Black farmers and Black farmland in US Agriculture is a direct result of social, political, and racial weaponization against their foodways, culture, and livelihoods. The history concerning the plight of Black farmers goes beyond USDA's historical discrimination but enters a position where racism is embedded and perpetuated within the structure of US agriculture. In effect, Black small-scale farmers have reaped the downfall of this system, enduring racial biases and …
