The Effectiveness Of A Preoperative Multimodal Antiemetic Regimen On Reducing Early Postoperative Nausea And Vomiting In Total Joint Arthroplasty Patients, Jerry Mosley

Doctoral Projects

Postoperative nausea and vomiting (PONV) occurs frequently in all types of surgeries including after total joint orthopedic procedures. The resulting PONV can lead to many unwanted occurrences including immobilization, distress, and many serious adverse health complications. These unwanted occurrences may then lead to increased cost to the patient and healthcare facility. Administration of a preoperative multimodal regimen known to reduce PONV has the potential to reduce such unwanted anesthetic side effects influencing a reduction in overall healthcare cost. The purpose of this study is to determine the effectiveness of the preoperative kit which includes the administration of metoclopramide, famotidine, ondansetron, …

Targeting Oncogenic Mirnas With Small Molecules For Breast Cancer Therapy, Paloma Del C. Monroig

Dissertations & Theses (Open Access)

The crucial role of microRNAs (miRNAs) in cancer pathobiology has driven the introduction of new drug development approaches such as miRNA inhibition. In order to advance miRNA-therapeutics, there is a need to develop screening strategies that can target tumors in a specific way. Small molecule inhibitors represent an attractive approach to pursue this. However, the absence of molecular structures for most of the miRNAs makes it very difficult to predict which inhibitors can bind to them. Herein we designed a strategy to screen for small molecules by assesing whether they could directly bind/ interact with miR-10b/miR-21. As part of our …

Instituting Patient-Self Test Meters In Adults On Warfarin In A Cardiology Practice, Melvyn Grace Manzano Rabanal

Doctor of Nursing Practice Final Manuscripts

Background: Warfarin is the oral anticoagulant that is most commonly used to control and prevent thromboembolic disorders. It requires meticulous testing and dosing adjustments to attain therapeutic international normalized ratio (INR) levels. Patient self-testing (PST) is associated with a reduced risk of all-cause mortality and lower rates of thromboembolism and bleeding. PST meters offers convenience and promotes self-initiative of care.

Purpose: The purpose of the project is to evaluate the effectiveness of INR PST in adult patients diagnosed with atrial fibrillation, deep vein thrombosis, and mechanical heart valve on warfarin therapy in a Cardiology practice compared to traditional …

Dual Pi3k/Mtor Inhibition With Bez235 Augments The Therapeutic Efficacy Of Doxorubicin In Cancer Without Influencing Cardiac Function, David E. Durrant

Theses and Dissertations

Cancer continues to be a leading cause death in the United States despite improved treatments. Cancerous lesions form after acquiring oncogenic driver mutations or losing tumor suppressor function in normal cells. Traditional therapies have included use of genotoxic substances that take advantage of the increased growth rate and loss of tumor suppressor function to cause cell death. One such drug is the anthracycline antibiotic doxorubicin (DOX). DOX interchelates into DNA and disrupts transcriptional machinery while also poisoning topoisomerase II. This results in single and double stranded DNA breaks, which if severe enough leads to either necrotic or apoptotic cell death. …

The Effect Of Cannabinoids On Triple Negative Breast Cancer Cells, Haley Dahl

Honors Theses

Triple Negative Breast Cancer (TNBC) is a difficult type of cancer to treat because it is negative for progesterone, estrogen, and HER-2 receptors. Because TNBC is negative for these three receptors, it does not respond to normal hormonal therapies. The purpose of my experiment is to see if different cannabinoids, compounds from the cannabis plants, could be used as alternative treatment options. These experiments employed three different cannabinoids: ajulemic acid, cannabidiol, and hemp oil. Cell viability was measured after 72 hours of treatment using a MTT assay. The results showed that the three cannabinoids could be used to effectively destroy …

Chronic Behavioral And Cognitive Deficits In A Rat Survival Model Of Organophosphate Toxicity, Beverly Huang

Theses and Dissertations

Organophosphates (OPs) are a major class of pesticides and nerve agents that elicit acute toxicity by inhibiting acetylcholinesterase (AChE), the enzyme responsible for the degradation of the neurotransmitter acetylcholine in the central and peripheral nervous systems. Acetylcholine accumulation following extensive AChE inhibition leads to an acute cholinergic syndrome characterized by autonomic dysfunction, involuntary movements, muscle fasciculations, respiratory distress, and seizures. Despite their classification as moderate to highly toxic, OP pesticides are the most widely used class of insecticides in the U.S., and are even more commonly used worldwide. Additionally, there is a growing concern that OP nerve agents could be …

Drug Interactions With Glutaredoxin Orthologues, Kahlilah R. Napper, Thomas C. Leeper, Ram Khattri, Daniel Morris, Caroline Davis

Williams Honors College, Honors Research Projects

Glutaredoxin, an enzymatic protein, is an important component of cell viability and function. It catalyzes reactions involved in DNA synthesis and innate immunity [1,4]. Glutaredoxin is also essential in antibiotic resistance in pathogenic bacterial species. Pseudomonas aeruginosa in particular is responsible for infecting the lung tissue of its human hosts, resulting in the development of pneumonia and cystic fibrosis [3]. Because glutaredoxin is pertinent in cell proliferation of eukaryotic and bacterial cells alike, medicinal fragments that take advantage of the subtle differences in protein structure of the orthologous proteins can be synthesized and enhanced to bind bacterial glutaredoxins, without inhibiting …
