Commentary On Immune System Associated Diseases Caused Byviruses: The Role Of Ebv, Dale L. Barnard, J. K. Li

Animal, Dairy, and Veterinary Science Faculty Publications

In her review using the human Epstein–Barr virus (EBV) as an example, Dr. Chen intends to illustrate how host immune systems have evolved in response to pathogens or in many cases co-evolved with pathogens. She discusses why EBV in most people causes what appears to be a self-limiting lymphoproliferative disease (or is it? See her discussion of autoimmune diseases and EBV), but in a very small proportion of individuals the virus causes malignant diseases of severe consequence. She reviews some of the plausible explanations that may include interactions of environmental and host genetic factors resulting in EBV associated malignancies. She …

Expression And Regulation Of Survivin In Prostate Cancer, Maygen K. Cardona

McNair Scholars Research Journal

Survivin is an Inhibitor of Apoptosis Protein (IAP), which makes it responsible for cell proliferation and survival by inhibiting regulated cell death and promoting mitosis. The exact role that it plays in prostate cancer is not yet fully understood; expression and regulation of Survivin is the primary focus of my project. The way Survivin was studied was through fractionating various cancer cells lines (LaPC-4, PC-3 E+, VCAP, C4-2 and DU145-Spindle, Round and Tight) and isolating the nuclear and cytosolic components. These fractionated samples were then treated and analyzed using Western Blot analysis being probed for nuclear and cytoplasmic Survivin, respectively. …

Issues In The Development Of Location Privacy Theory, Robert Minch

IT and Supply Chain Management Faculty Publications and Presentations

Issues in the development of location privacy theory are identified and organized based on both technological considerations and more general privacy theories. Three broad categories containing six issues are described: location (including sensing methods and location properties), privacy (including definition and subject identification), and information flows (from location information acquisition through storage, use, and sharing). An influence diagram model is presented which relates these issues in context and may serve as a basis for further theory development, empirical research, and public policy discussion.

Numerical Solutions For A Model Of Tissue Invasion And Migration Of Tumour Cells, Mikhail Kolev, Barbara Zubik-Kowal

Mathematics Faculty Publications and Presentations

The goal of this paper is to construct a new algorithm for the numerical simulations of the evolution of tumour invasion and metastasis. By means of mathematical model equations and their numerical solutions we investigate how cancer cells can produce and secrete matrix degradative enzymes, degrade extracellular matrix, and invade due to diffusion and haptotactic migration. For the numerical simulations of the interactions between the tumour cells and the surrounding tissue, we apply numerical approximations, which are spectrally accurate and based on small amounts of grid-points. Our numerical experiments illustrate the metastatic ability of tumour cells.

Subthalamic Nucleus Deep Brain Stimulation Changes Velopharyngeal Control In Parkinson’S Disease, Michael J. Hammer, Steven M. Barlow, Kelly E. Lyons, Rajesh Pahwa

Department of Special Education and Communication Disorders: Faculty Publications

Purpose

Adequate velopharyngeal control is essential for speech, but may be impaired in Parkinson’s disease (PD). Bilateral subthalamic nucleus deep brain stimulation (STN DBS) improves limb function in PD, but the effects on velopharyngeal control remain unknown. We tested whether STN DBS would change aerodynamic measures of velopharyngeal control, and whether these changes were correlated with limb function and stimulation settings.

Methods

Seventeen PD participants with bilateral STN DBS were tested within a morning session after a minimum of 12 h since their most recent dose of anti-PD medication. Testing occurred when STN DBS was on, and again 1 h …
