Methods Development In Inflammatory Bowel Disease, Andrew B. Steimke
Methods Development In Inflammatory Bowel Disease, Andrew B. Steimke
Theses and Dissertations (ETD)
Inflammatory bowel disease (IBD) is a disease that is classified into two subtypes: ulcerative colitis (UC) and Crohn’s disease (CD). Symptoms can range from mild discomfort to requiring surgical intervention and affects approximately 1-in-200 adults in America alone, with global incidence rates increasing. While many treatments exist for IBD, perhaps the main reason for the lack of a cure is that there are many different pathogeneses that all lead to a very similar expression of symptoms. Over 240 IBD loci have been identified to date, yet the causative allele that drives the association has only been identified in ~60 of …
Development Of A Low-Dose Radiation Therapy Device For Acute Respritory Distress Syndrome, Thomas Heath Davis
Development Of A Low-Dose Radiation Therapy Device For Acute Respritory Distress Syndrome, Thomas Heath Davis
Masters Theses
This research focuses on the development of a low dose radiotherapy (LD-RT) device for treatment of acute respiratory distress syndrome (ARDS), a respiratory illness that affects millions of people a year. The use of orthovoltage (200 – 500 keV) X-ray energy provides many advantages over traditional radiotherapy delivery with linear accelerators, such as low cost and greater accessibility. In addition, X-ray tubes have been shown throughout history to provide good treatment outcomes for pneumonia, and research has shown LD-RT to be just as effective with ARDS. This proposal summarizes my efforts in determining the dosimetric properties of a LD-RT system …

INDUCED CYOTOXICTY IN CREBBP/EP300mut HEAD AND NECK SQUAMOUS CELL CARCINOMA
Thomaia Pamplin
Advisor: Curtis Pickering, Ph.D.
Background: Head and neck squamous cell carcinoma HNSCC is the most common malignancy in the head and neck. Most cases are found in advanced stages and depending on the location can be treated with surgical resection and/or radiation (XRT), chemotherapy, or chemoradiation. Our lab groups have identified that HNSCC with a mutation in its CREBBP/EP300 genes can be sensitized to XRT when the histone acetyltransferase activity of CREBBP/EP300 is inhibited. This radiosensitization manifests in the form of increased cell death for …

Micro-Rna Analysis Of Extracellular Vesicles Secreted By Alveolar Macrophages And Epithelial Cells In Response To Cadmium, Anisha Bhakta
Biotechnology Theses
Inhalation of cadmium (Cd) has been an environmental health concern with the increase in industrial activities and smoking. Cd exposure is known to affect several organs such as lungs, kidneys, and liver. In this study, we wanted to understand if Cd inhalation exposure can affect the lungs and other organs in the body. Exosomes are extracellular vesicles secreted by all living cells and are known to carry toxicants between organs. We investigated whether Cd exposure could affect exosome biogenesis and their composition. Cd exposure did not affect the viability of A549, a lung epithelial cell line and macrophages derived from …
Hepatocellular Carcinoma Image-Guided Intervention: Quantitative Characterization Of Reagents For Thermochemical Ablation, Emily A. Thompson
Hepatocellular Carcinoma Image-Guided Intervention: Quantitative Characterization Of Reagents For Thermochemical Ablation, Emily A. Thompson
Dissertations & Theses (Open Access)
Thermochemical ablation (TCA) is a minimally invasive therapy under development for hepatocellular carcinoma, a leading cause of cancer death worldwide. TCA utilizes acid-base chemistry delivered simultaneously to induce local ablation when administered. When delivered via a mixing catheter placed directly into the tumor, acid (e.g., AcOH) and base (e.g., NaOH) react to completion at the catheter tip, producing the acetate salt, water, and releasing heat (Δ>50°C) in sufficient quantities to induce lethal osmotic and thermal stress in tumor cells. However, these two reagents are not distinguishable from tissues with noninvasive imaging modalities, which makes monitoring the delivery of TCA …

Doctor of Nursing Practice Scholarly Projects
Long-term video-electroencephalography (EEG) monitoring in the epilepsy monitoring unit (EMU) is an elective procedure and generally safe. Clinical experts determined the EMU protocols at a level-4 comprehensive epilepsy center were not followed correctly. The project is a retrospective chart audit incorporating Ray’s Bureaucratic Caring theoretical framework with Donabedian’s conceptual model. The project objective is to evaluate if safety measures protocols are implemented appropriately in the EMU and determine whether a need exists for quality improvements.
The project reviewed patients admitted to the EMU from September 2021 through November 2021 who developed a generalized tonic clonic (GTCs) seizure with electrographic epileptiform …
Impact Of Interleukin-34 On The Promotion Of Bone Osteolysis And Neuroinflammation In Experimental Models Of Alzheimer’S Disease, Anny Ho
All HCAS Student Capstones, Theses, and Dissertations
Alzheimer’s disease (AD) is a growing health concern and is the most common type of dementia worldwide. Emerging evidence indicates that aggregated amyloid-beta (Aβ) peptides, one of the hallmark features of AD neuropathology, can increase RANKL-mediated osteoclast activity leading to the prevalence and severity of inflammatory osteolysis, e.g., osteoporosis and periodontal bone loss. Conversely, osteolytic lesions are associated with increased risk of dementia diagnosis indicating that there is a direct link between dementia and inflammatory osteolysis. It was demonstrated that the neuronal cells primarily produce interleukin-34 (IL-34) and microglia, macrophages, and osteoclast precursors express colony-stimulating factor 1 receptor (CSF-1R), a …
Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley
Evaluation Of Hippocampal Allostatic Load-Associated Factors In Animal Models Of Post-Traumatic Stress Disorder: Relevance To Human Ptsd, Dennis Parker Kelley
LSU Doctoral Dissertations
Post-traumatic stress disorder (PTSD) is associated with elevated allostatic load, nearly double the risk for metabolic syndrome, reduced hippocampal volume, and contextual memory processing deficits. Emerging evidence suggests that these stress effects may predispose individuals to the development of PTSD, and there is a known relationship between chronic stress and metabolic dysfunction. In this work, we utilized two rat models of PTSD to explore these connections. We used an acute predator odor stressor to investigate the relationship between PTSD-like behaviors and mitochondrial dysfunction in the hippocampus of rats, and we observed that conditioned place avoidance was associated with reduced mitochondrial …
Investigating The Role Of Nlrp3 Inflammasome In Chemotherapy-Induced Peripheral Neuropathy, Urszula O. Warncke
Investigating The Role Of Nlrp3 Inflammasome In Chemotherapy-Induced Peripheral Neuropathy, Urszula O. Warncke
Theses and Dissertations
Paclitaxel and oxaliplatin are commonly used antineoplastic drugs that cause chemotherapy-induce peripheral neuropathy (CIPN) in up to 90% of patients. The sensory symptoms of CIPN include numbness, loss of proprioception, tingling, spontaneous burning, shooting or electric shock-like pain, mechanical and thermal allodynia, and cold hypersensitivity among others. Affected patients struggle with daily activities, have a low quality of life, and might stop cancer treatment. Unfortunately, there are no effective prophylactic or therapeutic treatments for these side effects. Many studies point to the involvement of inflammation as a major contributor of CIPN pathology. We investigated the effects of genetic (NLRP3 …

Increasing Awareness Of Personal Harm Reduction Interventions In The Clinical Setting: A Quality Improvement Project, Shawn Theberge
DNP Scholarly Projects
Abstract
The ever-rising concern for safety in the healthcare setting has become increasingly prevalent and levels of hostility and violence more publicly visible. Over the last decade both patients and clinicians have been targeted in healthcare facilities at record levels. These incidents have created an environment of not only risk but increased anxiety and feelings of uncertainty for most clinical personnel. The study will initially measure clinician’s viewpoint of the clinical setting that they work in; and over the span of the project, track and evaluate the effects of the interventions on clinicians’ overall feelings and perceptions. The expected outcome …

In this project we completed a deep dive into how the Covid-19 pandemic reshaped our mental health and has affected our preparation for careers as registered nurses through a series of auto- ethnographic narrative journals using scholarly articles to support this idea. By utilizing personal narratives, we analyzed and reflected upon the cognitive and mental changes we experienced throughout this pandemic. We fulfilled this by comprising two personal narratives with inquiries pertaining to each shared narrative by utilizing the common themes of being nursing students and living through a pandemic. Within these personal narratives, we discussed how the pandemic influenced …
Effectiveness Of Stabilized Hypochlorous Acid In Acute Peritonitis Treatment: A Murine Surgical Study, Benjamin Michael Pomeroy
Effectiveness Of Stabilized Hypochlorous Acid In Acute Peritonitis Treatment: A Murine Surgical Study, Benjamin Michael Pomeroy
MSU Graduate Theses
Peritonitis is an inflammatory condition affecting the mesothelial cells that line the peritoneal cavity and is commonly induced by bowel perforations. This medical emergency is treated through antibiotic therapy and surgical intervention followed by tissue irrigation (lavage). Acute treatments aim to remove the bacterial burden, however recurring peritoneal infections occur at high rates and contribute to patient morbidity. These recurring infections are likely due to the inability of lavage solutions to remove the entire massive intra-abdominal bacterial load due to intestinal perforation. Numerous antiseptic solutions and antibiotic additives have been evaluated in their ability to improve source control by abdominal …
