Evaluation Of The Role Of Microvascular Pathology On Peripheral Artery Disease, Constance Mietus
Evaluation Of The Role Of Microvascular Pathology On Peripheral Artery Disease, Constance Mietus
Theses & Dissertations
Background: Peripheral Artery Disease (PAD) begins with atherosclerotic narrowing of arteries, including those that supply the legs. Individuals with PAD experience pain during walking, which becomes increasingly limiting. Studies from our group and others have shown that a myopathy is present in the skeletal muscle of PAD patients, and is characterized by myofiber degeneration, fibrosis, and remodeling of vessels ranging from 50 – 150 mm in diameter. However, microvascular pathology, particularly of the smallest microvessels (5 – 15 mm in diameter) remains poorly characterized. Furthermore, little is known about the relationships between microvascular architecture, microperfusion, and patient walking performance. We …
Monocyte Anti-Inflammatory Activity Is Dictated By Metabolic Status During Staphylococcus Aureus Biofilm Infection, Kelsey J. Yamada
Monocyte Anti-Inflammatory Activity Is Dictated By Metabolic Status During Staphylococcus Aureus Biofilm Infection, Kelsey J. Yamada
Theses & Dissertations
Staphylococcus aureus biofilms represent a significant cause of morbidity and economic burden and are often associated with nosocomial infections, including medically implanted devices. In particular, prosthetic joint infections (PJIs) are a growing concern due to the continued increase in orthopedic procedures. Staphylococcal species cause >50% of all PJIs, while S. aureus represents the most invasive and associated with the most morbidity. S. aureus-associated biofilm infections are recalcitrant to antibiotic therapy, due to both the acquisition of genetic elements and metabolic dormancy. Furthermore, S. aureus biofilm infections remain chronic because they cannot be cleared by the immune system. Recent studies …
Neurological Balance Assessment To Screen Fall Risk: A Methodological Study, Yiwen Xia
Neurological Balance Assessment To Screen Fall Risk: A Methodological Study, Yiwen Xia
Theses & Dissertations
According to the World Health Organization, falls are the second leading cause of accidental or unintentional injury deaths worldwide. The medical cost on fall related injuries becomes a huge financial burden. In order to prevent falls and fall related injuries, fall risk assessment becomes a routine practice for healthcare providers. In most clinics, practitioners conduct a quick neurological balance assessment in the room or along the hallway to determine abnormal gait pattern, indicating increased risk of falls. However, the validity of such subjective assessment is questionable. The purpose of this study was to identify a single feasible neurological balance task …
The Role Of Ros In The Progression And Treatment Of Castration-Resistant Prostate Cancer, Dannah R. Miller
The Role Of Ros In The Progression And Treatment Of Castration-Resistant Prostate Cancer, Dannah R. Miller
Theses & Dissertations
Prostate cancer is the second leading cause of cancer-related deaths in U.S. men, primarily due to the development of castration-resistant (CR) prostate cancer (PCa), of which there are no effective treatment options. Reactive oxygen species (ROS) plays a critical role in prostate carcinogenesis, including the progression of the CR PCa phenotype. ROS regulates both cell proliferation and apoptosis; a moderate increase in ROS can promote proliferation; however, a substantial rise in ROS levels will result in apoptosis. Oxidase p66Shc is elevated in clinical PCa cells and has been associated with a metastatic phenotype of CR PCa cells, promoting PCa cell …

Human Immunodeficiency Virus Theranostics, Christopher J. Woldstad
Theses & Dissertations
RATIONALE: Long-acting slow effective release antiretroviral therapy (LASER ART) was developed to improve patient regimen adherence, prevent new infections, and facilitate drug delivery to human immunodeficiency virus cell and tissue reservoirs. However, maintenance of sustained plasma drug levels, for weeks or months, after a single high-level dosing, could improve regimen adherence but, at the same time, affect systemic toxicities. Of these, the most troubling are those that affect the central nervous system (CNS) In an effort to facilitate LASER ART development, “multimodal imaging theranostic nanoprobes” were created. These allow combined bioimaging, drug pharmacokinetics and tissue biodistribution tests in animal …

Polymeric Chloroquine: Modifying An Old Drug To Make It A Little Sweeter, Richard Sleightholm

Hydroxyethyl starch (HES) is a clinically used polysaccharide colloidal plasma volume expander. The goal of this study was to synthesize HES modified with hydroxychloroquine (HCQ) as a novel polymeric drug with the ability to inhibit the invasive character of pancreatic cancer (PC) cells. HES was conjugated with HCQ using a simple carbonyldiimidazole coupling to prepare Chloroquine-modified HES (CQ-HES). CQ-HES with various degrees of HCQ substitution were synthesized and characterized. In vitro studies showed CQ-HES to have a similar toxicity profile as HCQ. Confocal microscopy revealed the propensity of CQ-HES to localize to lysosomes, and mechanistic studies confirmed the ability of …
