Characterization And Investigation Of Cold Atmospheric Plasma And Its Effects On Cancer Cell Biology, Thomas M. Ritrosky Jan 2023

Characterization And Investigation Of Cold Atmospheric Plasma And Its Effects On Cancer Cell Biology, Thomas M. Ritrosky

Theses and Dissertations

Modern cancer treatment uses radiation therapy in over 50% of patient cases. It is an e↵ective way of treating tumors because the mechanisms of cell killing are well known through the damage that ionizing radiation does to DNA. The amount of radiation can be tracked through measuring the dose of the clinical photon or electron beam used. However, there are limitations in the usage of radiation therapy, for example, a tumor can create hypoxic areas that become radioresistant leading to complete ine↵ectiveness of further radiation treatment. This project looks into the application of cold atmospheric plasma as an adjuvant therapy …

Inherited ophthalmic diseases impact individuals around the globe. Inherited retinal diseases (IRDs) are the leading cause of blindness in individuals aged 15 to 45. The personal, social, and economic impact of vision loss is profound. Due to individual differences, symptoms can be variable, and …


Interactions Between Hiv And Opioids On Antiretroviral Accumulation, The Blood Brain Barrier, And The Inflammatory Response In The Brain., Kara Rademeyer Jan 2023

Interactions Between Hiv And Opioids On Antiretroviral Accumulation, The Blood Brain Barrier, And The Inflammatory Response In The Brain., Kara Rademeyer

Theses and Dissertations

The complex mechanisms related to HIV infection, neurodegeneration, and chronic neuroinflammation collectively describe neuroHIV (Hauser et al. 2007; Chang et al. 2014; Smith et al. 2014). Specifically, opioid abuse, poor penetration of antiretroviral (ARV) drugs, chronic inflammation and neuronal injury/degeneration are all implicated in neuroHIV (Fantuzzi et al. 2003; Letendre et al. 2004; Verani et al. 2005; Duncan and Sattentau 2011; Hong and Banks 2015; Simoes and Justino 2015; Olivier et al. 2018; Murphy et al. 2019; Osborne et al. 2020). For the first time, we demonstrate that morphine, fentanyl, and methadone in vivo alter the brain accumulation of ARVs, …


Prospective Investigation Of Insomnia Symptoms And Sleep Duration As Risk Factors For Stroke Incidence And All-Cause Mortality In U.S Adult, Wendemi Sawadogo Jan 2023

Prospective Investigation Of Insomnia Symptoms And Sleep Duration As Risk Factors For Stroke Incidence And All-Cause Mortality In U.S Adult, Wendemi Sawadogo

Theses and Dissertations

Background and Objectives: Stroke is the second leading cause of death in the world. In the United States, on average, someone has a stroke every 40 seconds and someone dies as a result of stroke every 3.5 minutes. Identifying modifiable risk factors of stroke is therefore a public health priority. The purpose of this study was to investigate the extent to which insomnia symptoms and sleep duration contribute to stroke incidence, all-cause mortality, and explore potential causal pathways.

Methods: The Health and Retirement Study (HRS) and the REasons for Geographic And Racial Differences in Stroke (REGARDS) study were …
