A Pattern Matching Algorithm For Self-Adjusting Basal Rates In Insulin Pump Systems, Lauren Smith

Doctoral Dissertations

In a Type 1 Diabetic, Insulin can be administered in a pump system. There are two types of insulin that must be given: basal and bolus. Basal insulin is a long-acting form of insulin that works in the background while fasting, while Bolus insulin is rapid/short acting given in response to food to immediately begin working to lower blood sugar.

Modeling in Diabetes can be represented by algorithmic approaches ranging from simple autoregressive models of the Continuous Glucose Monitor time series to multivariate nonlinear regression techniques of machine learning. Other examples of modeling in Diabetes include prediction models of hypoglycemia …

Implantable Medical Devices For Local Drug Delivery And Tissue Regeneration To Combat Chronic Bacterial Infection, Caroline J. Billings

Doctoral Dissertations

Local drug delivery has been an area of exceptional interest in the treatment of chronic bacterial infections, particularly in areas where there are medical implants placed. Medical implants are widely utilized and are becoming increasingly popular with time. With the increasing use of medical implants, concomitant bacterial infection is also increasing, and this type of bacterial infection can be exceedingly difficult to clear. The following body of work focuses on implant-associated bacterial infection, with an emphasis on chronic Staphylococcus aureus (S. aureus) infection, particularly osteomyelitis. Specifically, this work is focused within the scope of utilizing locally implantable medical …

Anti-Inflammatory And Chemopreventive Activity Of Lunasin From Tofu Whey For The Management Of Gastrointestinal Diseases, Cindy Andrea Nieto Veloza

Doctoral Dissertations

Gastrointestinal diseases such as inflammatory bowel diseases (IBD) and colorectal cancer (CRC) are pathological conditions associated with chronic inflammation, characterized by intestinal damage, debilitating symptoms, and detrimental health consequences. The increased risk of CRC in IBD patients, and the adverse effects associated with current therapeutic strategies, point out the need for safer alternatives to reduce chronic inflammation in the bowel. Lunasin is a bioactive peptide naturally occurring in soybeans, with chemopreventive and anti-inflammatory properties demonstrated in several extra-intestinal diseases. However, to date, there is no evidence of the biological activity of lunasin on the gastrointestinal tract as a target site. …

Geographic And Socioeconomic Risk Factors For Sporadic Cryptosdporidiosis And E. Coli Infection In East Tennessee, Ingrid Elizabeth Luffman

Doctoral Dissertations

This research examines risk factors for sporadic cryptosporidiosis and Escherichia coli (E. coli) O157 infection in East Tennessee, using case-control and retrospective ecological approaches. Multiple models and approaches are used to identify risk factors for the two diseases, and to examine the effect of scale on risk for disease in the individual and in the population. Risk factors examined are animal density, land use, geology, surface water impairment, poverty rate and availability of private water supply. The research objectives are, first, to identify risk factors for E. coli O157 and cryptosporidiosis in East Tennessee by relating disease data …

Modulating T Cell Responses To Control Stromal Keratitis, Tamara Antia Veiga Parga

Doctoral Dissertations

Herpetic stromal keratitis (SK) is an immunoinflammatory corneal lesion caused by herpes simplex virus (HSV) infection. This infection, in some cases, can result in a chronic immunoinflammatory lesion that is the most common cause of infectious blindness in the developed world. Studies in animal models have revealed that SK lesions are orchestrated mainly by IFN-gamma producing CD4+ T cells (Th1) and neutrophils that infiltrate the corneal stroma.

The first part of this dissertation (I) reviews literature on HSV induced corneal SK immunopathology and the role of Tregs in viral infections. It also focuses on the understanding of HSV-1 induced immunoinflammatory …
