Targeting Cancer-Anorexia Cachexia Syndrome And Septic Inflammatory-Based Atrophy With R/S 1,3 Butanediol Acetoacetate Diester, Andrew P. Koutnik

USF Tampa Graduate Theses and Dissertations

Cancer anorexia cachexia syndrome (CACS) is a distinct atrophy disease negatively influencing multiple aspects of clinical care and patient quality of life. Although it directly causes 20% of all cancer-related deaths, there are currently no model systems that encompass the entire multifaceted syndrome, nor are there any effective therapeutic treatments. Here, we show that the VM-M3 mouse model of systemic metastasis demonstrates a novel, immunocompetent, logistically feasible, repeatable phenotype with progressive tumor growth, spontaneous metastatic spread, and the full multifaceted CACS with expected sex dimorphisms across tissue wasting. We also demonstrate that the ubiquitin proteasomal degradation pathway was significantly upregulated …

The Location Of Sensing Determines The Pancreatic Β-Cell Response To The Viral Mimetic Dsrna, Zachary R. Shaheen, Joshua D. Stafford, Michael G. Voss, Bryndon J. Oleson, Jennifer S. Stancill, John A. Corbett

Biological Sciences Faculty Research & Creative Works

Viral infection is an environmental trigger that has been suggested to initiate pancreatic β-cell damage, leading to the development of autoimmune diabetes. Viruses potently activate the immune system and can damage β-cells by either directly infecting them or stimulating the production of secondary effector molecules (such as proinflammatory cytokines) during bystander activation. However, how and where β-cells recognize viruses is unclear, and the antiviral responses that are initiated following virus recognition are incompletely understood. In this study, we show that the β-cell response to dsRNA, a viral replication intermediate known to activate antiviral responses, is determined by the cellular location …

A&P Workshop Summary—Uniting Anatomy And Physiology Through Case Studies, Angela Horner, Stuart Sumida, Tomasz Owercowicz

Q2S Enhancing Pedagogy

Introducing problem-solving based methods of pedagogy is one approach to engage students early in their careers with developing analytic and diagnostic skills. PBL approaches in anatomy and medical teaching are a logical extension of clinical case studies, wherein an example of a pathology or clinical procedure is provided, and students must ascertain the anatomical and/or physiological basis for it. Students report a deeper understanding of material presented in clinical case studies, as the ‘real world’ relevance and importance is immediately clear (Cliff and Wright, 1996).
