Cell Type-Specific Roles Of Stat3 Signaling In The Pathogenesis And Progression Of K-Ras Mutant Lung Adenocarcinoma, Michael J Clowers, Seyed Javad Moghaddam

Faculty, Staff and Student Publications

Worldwide, lung cancer, particularly K-ras mutant lung adenocarcinoma (KM-LUAD), is the leading cause of cancer mortality because of its high incidence and low cure rate. To treat and prevent KM-LUAD, there is an urgent unmet need for alternative strategies targeting downstream effectors of K-ras and/or its cooperating pathways. Tumor-promoting inflammation, an enabling hallmark of cancer, strongly participates in the development and progression of KM-LUAD. However, our knowledge of the dynamic inflammatory mechanisms, immunomodulatory pathways, and cell-specific molecular signals mediating K-ras-induced lung tumorigenesis is substantially deficient. Nevertheless, within this signaling complexity, an inflammatory pathway is emerging as a druggable target: signal …

Attempted Synthesis & Antibacterial Properties Of Apt-6k Against Ndm-1 K. Pneumoniae, Alec Bofetiado

Honors Theses

NDM-1 K. pneumoniae is a highly resistant bacterial organism that is capable of causing debilitating nosocomial infections in immunocompromised patients. Only "last-resort" antibiotics--such as colistin--work against this organism. Therefore, new antibiotics are needed to help fight against these types of infections. APT-6K is a novel compound that was demonstrated to be effective against MRSA with nanomolar concentrations in a prior study. Novel methods of APT-6K synthesis and its testing for antibiotic effects against NDM-1 K. pneumoniae were attempted in this research. APT-6K synthesis was unsuccessful. Commercially-prepared APT-6K also did not demonstrate growth inhibition against NDM-1 K. pneumoniae nor against a …

Exploring The Relationship Between Student Expected Engagement And Referrals To The Behavioral Intervention Team, Makenzie R. Schiemann

USF Tampa Graduate Theses and Dissertations

Higher education administrators are tasked with supporting and retaining students with increasing needs. These needs often include emotional and mental health issues but can worsen to include suicidality and violence toward others. Traditional campus approaches for supporting students and intervening for violence, such as counseling and campus safety, have been reactionary rather than proactive. Behavioral Intervention Teams (BITs) have emerged as a mechanism for heading off violence before it occurs while also supporting students who may never engage in violence but need support. These teams were born out of the concept that violence is preventable and have grown into a …
