The Effects Of Exercise On Innate Lymphoid Cell Metabolism And Function In Cancer, Eunhan Cho

LSU Doctoral Dissertations

Immunosenescence refers to the gradual decrease in immune competency over time, which is strongly associated with increased risk of cancer and a rise in morbidity and mortality among the elderly. Regular physical activity can be beneficial to the immune system by potentially decreasing the frequency of senescent immune cells and reducing mortality risk in cancer patients and survivors. However, less is known on the impact of acute exercise on “aggressive” cancers, such as hormone receptor negative breast cancers. Further, the mechanistic underpinnings of the exercise-associated improvements in the immune response to cancer remains unclear. In this context, past studies have …

Prevalence Of Mortality Among Covid-19 Patients In Kurdistan Region And Various Parts Of The World And The Role Of Ecological And Environmental Factors In Shaping Sars-Cov-2 Virulence, Muayad A. Mahmud

Polytechnic Journal

Evolutionary theories predict that virulence (host death due to a pathogen) positively associates with the pathogen transmission rates to new susceptible hosts. Severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2), the causative agent of coronavirus disease 2019 (covid-19) pandemic, like other RNA viruses, has quite variable genetic content due to its unique nucleus enzymes thus mutations can continuously occur during viral replications. Phenotype variations among new viral progeny can include individuals with different replication rates, infectivity, stability in the abiotic environment, and transmission rate. Here, the rate of transmission to new susceptible hosts may be affected by the pathogen’s vitality …

Without Permanence: Mapping Multi-Genre, Cross-Disciplinary Frameworks For Trans* Studies, Jesse Jack

Electronic Theses and Dissertations

This project takes a cross-disciplinary and multi-genre approach to Transgender (Trans*) Studies to proliferate diverse and ambiguously-gendered representations of trans* experiences across time. It identifies the emergence of rhetorical intertextuality in recent trans* literatures as a discursive response to the biopolitical regulation and erasure of ambiguously-gendered, trans* experiences. It identifies the intersecting influences of twentieth- and twenty-first-century medical paradigms, surveillance apparatuses, popular trans* autobiographies, and archives in representing and exceptionalizing certain trans* experiences over others. In contrast, this project engages in a close reading of Pajtim Statovci’s Crossing (2016) and Andrea Lawlor’s Paul Takes the Form of a Mortal Girl …

Novel Signal Sequences And Fusion Partners For Paratransgenesis In Asaia, Christina Grogan

Electronic Theses and Dissertations

Mosquitoes transmit many pathogens that cause human disease. One such disease, malaria, is caused by parasites in the genus Plasmodium, infecting over 200 million people and killing over 600,000 per year. Current strategies to control vector-transmitted diseases are increasingly undermined by mosquito and pathogen resistance. Research has turned to additional and novel methods of control, such as altering the microbiota of the vectors. In this method, called paratransgenesis, symbiotic bacteria are genetically modified to affect the mosquito’s phenotype by engineering them to deliver antiplasmodial molecules into the midgut to kill parasites. These molecules must be released by the …
