Nuclear-Targeted Gold Nanoparticles Enhance The Effects Of Radiation Therapy With And Without Liposomal Delivery, Maureen Aliru

Dissertations & Theses (Open Access)

Less that 10% of pancreatic cancer patients are eligible for curative resection, and clinical trials evaluating chemoradiation in locally advanced patients with unresectable disease have been largely disappointing. New and creative therapeutic approaches are needed to address the unment need for treatment options. The objective of this thesis is to advance radiosensitization of treatment-resistant densely desmoplastic pancreatic cancer using nanoparticles to surmount biological barriers to effective particle distribution for DNA-targeting.

Clinical translation of radiosensitizing nanoparticles has stalled owing to technical challenges. Current strategies to use AuNPs for radiosensitization require large quantities of gold, kilovoltage x-rays, immediate irradiation after intravenous administration, …

Modeling Anatomic Changes For Adaptive Radiotherapy In Locally Advanced Lung Cancer Patient Population, James Alexander Kavanaugh

LSU Doctoral Dissertations

Anatomic changes occurring mid-treatment for patients undergoing radiation therapy for locally advanced lung cancer can degrade the quality of the intended treatment plan. These changes include tumor regression, geometric misalignment, and lung density changes (atelectasis and pleural effusion), and are visible on the daily 3D cone beam CT (CBCT). To maintain the intended treatment quality, adaptive radiotherapy (ART) can be employed to modify the treatment plan to account for these anatomic changes. However, the evaluation on when to adapt is currently completed manually by the treating clinicians, resulting in a subjective and inconsistent application. To address these limitations, a series …

Chronic Pain, Sleep Disruption, And Work Performance In The Military, Jeffrey Ransom

Dissertations

Abstract

Background and Significance: Managing pain is a challenge for many organizations, including the U.S. military. The added complication of managing sleep disruption compounds the issue. Examining pain and sleep disruption in the context of work performance within the military is critical to understanding the impact of these conditions on our nation’s fighting forces.

Purpose: Examine the associations of chronic pain and sleep disruption in the context of work performance among active duty military service members.

Research Aims: 1) Describe sociodemographic characteristics, military service characteristics, clinical characteristics, and work performance of active duty service members, 2) Examine relationships between these …

The Use Of Animal-Assisted Therapeutic Interventions In The Hospital Setting During The Covid-19 Pandemic, Alicia Cesare

MSU Graduate Theses

Handlers of therapy and/or facility dogs working within hospital settings have experienced various barriers and challenges within their practice during the COVID-19 pandemic. Animal-assisted interventions, specifically therapeutic working dogs, are a valued source of support to individuals, communities, hospital settings, and disaster sites during times of community distress. The purpose of this study was to identify barriers and solutions to the continued use of animal-assisted therapeutic interventions in support of patients and families within the hospital setting during the COVID-19 pandemic. This researcher’s position within the research is the knowledge and experience of being a facility dog handler within the …

A Protocol Driven Stroke Code's Impact On Door-To-Needle Times, Jesse Osborne

Electronic Theses and Dissertations

Tissue plasminogen activator (tPA) is most effective the faster it is able to be administered to a patient that has been affected by stroke. A Stroke Code is a strategy that acute care facilities implement to reduce the time from diagnosing a stroke to administering tPA. The purpose of this study was to determine if the initiation of a Stroke Code in an acute care hospital reduces the door-to-needle time for patients affected by a stroke. In particular, does a Stroke Code reduce door-to-needle times. The research was conducted using data from April 1, 2014 to December 31, 2014 (pre-Stroke …

Developing A Novel Bioink From Hyaluronic Acid-Alginate-Silk Fibroin (Ha- Alg-Sf) For Cartilage 3d Printing, Truc Thanh Nguyen

Chulalongkorn University Theses and Dissertations (Chula ETD)

In the development of a bioink for cartilage 3D printing, Hyaluronic acid (HA), Alginate (Alg) were modified into amine-hyaluronic acid (HA-NH2) and aldehyde alginate (Alg-CHO). Magnetic Nuclear Resonance (NMR) and Fourier Transform Infrared Spectroscopy (FTIR) confirmed the successful modification of HA-NH2 and Alg-CHO. The hydrogel HA-Alg was crosslinked as a result of Schiff's base reaction, between primary amines and aldehydes to form imine bonds. By varying volume ratios, the optimal hydrogel HA-Alg (5:5) exhibited its printability, biocompatibility, and functionality as a bioink for cartilage tissue. HA-Alg (5:5) was printable with a custom-made extrusion 3D printer, had slow degradation, shear-thinning behavior, …
