Positron Emission Tomography In Oncology And Environmental Science, Samantha Delaney

Dissertations, Theses, and Capstone Projects

The last half century has played witness to the onset of molecular imaging for the clinical assessment of physiological targets. While several medical imaging modalities allow for the visualization of the functional and anatomical properties of humans and living systems, few offer accurate quantitation and the ability to detect biochemical processes with low-administered drug mass doses. This limits how physicians and scientists may diagnose and treat medical issues, such as cancer, disease, and foreign agents.

A promising alternative to extant invasive procedures and suboptimal imaging modalities to assess the nature of a biological environment is the use of positron emission …

Neuroinflammation Levels Measured By Microglial Cell Activation, Emma G. Whitlock, Linda S. Yasui

Honors Capstones

Neuroinflammation is an inflammatory response in the brain that can be caused by different stressors such as diseases and/or external factors such as traumatic brain injuries. It is important to note duration and intensity of neuroinflammation levels when determining the impacts of these stressors to the brain environment. During neuroinflammation, a type of immune cell that becomes activated in the brain is called microglial cells. Microglial cells play a role in progression of the pathophysiological effects from the brain stressor. Studying changes in microglial cell shape provides evidence of the degree of neuroinflammation in the brain. Researchers can quantify neuroinflammation …

Investigation Of Avaren-Fc's Therapeutic Potential Against Ovarian Cancer., Katarina Lee Mayer

Electronic Theses and Dissertations

This thesis describes the investigation of Avaren-Fc (AvFc), a novel lectin-based therapeutic fusion protein consisting of the recombinant Avaren lectin and the Fc region of human IgG1, against ovarian cancer. AvFc possesses selectivity toward tumor associated N-linked high-mannose-type glycans. The present study demonstrates AvFc’s in vitro activity against OVCA cell lines via antibody-dependent cell-mediated cytotoxicity and its ability to extend the survival of mice challenged with murine ID8 OVCA cells after repeated systemic administration. Furthermore, AvFc treatment in this model was found to increase the presence of peritoneal leukocytes, suggesting a shift toward an improved antitumor immune response. Another key …
