Biphasic Effects Of Vanadium Sulfate On Cerebrovascular Endothelial Cell Barrier Integrity, Yoselin Ordonez Suarez

Pharmaceutical Sciences ETDs

The objective of this study was to investigate the biphasic effects of vanadyl sulfate in cerebral vascular endothelial cells with a focus on understanding the mechanisms underlying vanadyl sulfate benefits. To first address the effects of vanadyl sulfate on endothelial permeability, mouse cerebrovascular endothelial cells were grown to confluence in 96-well electrode ECIS plates and treated with three different vanadium containing compounds: vanadyl sulfate, vanadium pentoxide, and ammonium metavanadate. Resistance of the endothelial cell monolayer was measured at 4kHz for 24 hours for different concentrations of vanadium containing compounds. The mouse cerebrovascular endothelial cells were also treated with different concentrations …

Serotonin Syndrome And/Or Opioid Withdrawal After The First Dose Of Naltrexone Hcl/Bupropion Hcl: An Observational Study, Stefanie J. Logothetis

Pharmaceutical Sciences ETDs

In 2014, the Food and Drug Administration approved naltrexone HCl/bupropion HCl, a combination of an antidepressant and an opioid antagonist for chronic weight management therapy. Concurrent use of antidepressants and opioids has the potential to cause drug interactions involving serotonin syndrome. Our primary objective is to identify cases of serotonin syndrome and/or opioid withdrawal after initiation of naltrexone HCl/bupropion HCl. Our secondary objective is to assess which specific opioids are more likely to cause a drug interaction with naltrexone HCl/bupropion HCl. We performed an observational study by reviewing cases in the RADARS^® database from January 2014 through December 2018. …

The Development Of Hybrid Process Control Systems For Fluidized Bed Pellet Coating Processes, Hanzhou Feng

Electronic Theses and Dissertations

The conventional basic control for pharmaceutical batch processes has several drawbacks. The basic control often uses constant process settings discovered by trial and error. The rigid process operation provides limited process understanding and forgoes the opportunities of process optimization. Product quality attributes are measured by the low efficient off-line tests, therefore these cannot be used to monitor and inform the process to make appropriate adjustments. Frequent reprocessing and batch failures are possible consequences if the process is not under effective control. These issues raise serious concerns of the process capability of a pharmaceutical manufacturing process.

An alternative process control strategy …

Modeling And Prediction Of Amorphous Solid Dispersion Formation Using A Molecular Descriptor, Kevin Deboyace

Electronic Theses and Dissertations

Poor aqueous solubility of an active pharmaceutical ingredient (API) is a significant hurdle during drug development. Delivering a drug in its amorphous solid-state is a potential method to overcome this issue, since the amorphous form has increased apparent aqueous solubility. However, the amorphous state is only metastable, and is thermodynamically driven to recrystallize. As a result, pure amorphous drugs are seldom used in marketed products. Intimately mixing a drug in its amorphous form with a polymer, known as an amorphous solid dispersion (ASD), has the potential to significantly extend the physical stability of the amorphous form, while maintaining the benefit …

A Multifaceted Approach To Antibiotic Stewardship In The Outpatient Clinical Setting For Bronchitis, Elizabeth A. Weaver

Evidence-Based Practice Project Reports

Antimicrobial resistance is a world-wide health crisis (Infectious Disease Society of America [IDSA], 2016; World Health Organization [WHO], 2017) expedited by the overuse/inappropriate use of antibiotics. In the outpatient setting it has been determined that approximately 60% of antibiotic therapies are prescribed (Centers for Disease Control and Prevention [CDC], 2016). Antibiotic stewardship is the coordinated effort to improve the use of antibiotic therapies, minimize misdiagnosis and delayed diagnosis and select appropriate antibiotic drug regimens (IDSA, 2016). The purpose of this evidence-based practice project was to evaluate the effects of an antibiotic stewardship program (presentation, survey collection, bimonthly e-mail reminders, patient …

A Comprehensive Examination Of University Of Mississippi Early Entry Students’ Perceptions Of Mental Illness, Brianna Gray

Honors Theses

Mental disorders affect nearly 1 in 5 adults in the United States in a given year, and that number is steadily increasing. Pharmacists, being some of the most accessible and frequently contacted health care professionals, must be prepared to provide support for these patients. They can play a key role in whether or not there is a positive patient outcome. Education can play a role in pharmacists’ comfort with and knowledge of mental illness. The primary objective of this study was to determine if University of Mississippi early-entry pharmacy students’ mental illness knowledge, familiarity, and acceptable social distance affected their …

Neurotoxic Effects Of Hiv-1 Gp120 And Interaction With Allopregnanolone, Kimberly A. Thornton

Honors Theses

With increasing incidence of HIV and its associated neurocognitive disorders, there has emerged a need for an antiviral with improved delivery to the CNS. In searching for drug candidates that meet these criteria, some have noted that certain steroid hormones like estrogen and progesterone that naturally accumulate in the CNS show neuroprotective effects in cells exposed to HIV proteins. This investigation focused on testing the potential protective effects of the progesterone metabolite, allopregnanolone (AlloP), against HIV protein gp120-mediated neurotoxicity. Experiments were conducted using SH-SY5Y neuroblastoma cells that were exposed to varying concentrations of AlloP (0-100 nM) in conjunction with one …

Deregulation Of A Network Of Mrna And Mirna Genes Reveals That Ck2 And Mek Inhibitors May Synergize To Induce Apoptosis Kras-Active Nsclc, Madeline Krentz Gober, Robert M. Flight, Joshua W. Lambert, Hunter N. B. Moseley, Arnold Stromberg, Esther P. Black

Pharmaceutical Sciences Faculty Publications

KRAS-activation mutations occur in 25% to 40% of lung adenocarcinomas and are a known mechanism of epidermal growth factor receptor inhibitor (EGFRI) resistance. There are currently no targeted therapies approved specifically for the treatment of KRAS-active non–small cell lung cancers (NSCLC). Attempts to target mutant KRAS have failed in clinical studies leaving no targeted therapy option for these patients. To circumvent targeting KRAS directly, we hypothesized that targeting proteins connected to KRAS function rather than targeting KRAS directly could induce cell death in KRAS-active NSCLC cells. To identify potential targets, we leveraged 2 gene expression data sets derived from NSCLC …

Introduction: Antibiotic use is an important risk factor for Clostridium difficile infection (CDI). Prior meta-analyses have identified antibiotics and antibiotic classes that pose the greatest risk for CDI; however, CDI epidemiology is constantly changing and contemporary analyses are needed.

Objectives: The objective of this study was to evaluate the association between CDI and important antibiotic classes in recent years using the FDA Adverse Event Report System (FAERS).

Methods: FAERS reports from January 1, 2015 to December 31, 2017 were analyzed. The Medical Dictionary for Regulatory Activities (MedDRA) was used to identify CDI cases. We computed the Reporting Odds Ratios (RORs) …

Development Of Approaches Of Tumor Trapping Enhanced Bb2r-Targeted Radiopharmaceuticals For Prostate Cancer, Wenting Zhang

Theses & Dissertations

The Gastrin-Releasing Peptide Receptor (BB2r) has been intensively investigated as a cancer target over the years. Numerous diagnostic and therapeutic BB2r-targeted agents have been developed for various solid tumors, including prostate cancers, due to the high expression level of BB2r on neoplastic relative to normal tissues. The development of those targeted agents have mainly utilized the modified c-terminal of bombesin(BBN), a peptide that has nanomolar binding affinity to human BB2r. However, a major issue that hinders the clinical translational potential of low-molecular weight, receptor-targted agents, is their short residence time at tumor tissues due to the intrinsically high diffusion and …

Synthesis And Characterization Of A Long-Acting Emtricitabine Prodrug Nanoformulation, Ibrahim M. Ibrahim

Theses & Dissertations

The introduction of highly active antiretroviral therapy led to a paradigm shift in the management of HIV/AIDS changing a disease considered “a death sentence” to “a manageable chronic disease”. Nevertheless, challenges exist for successful treatment of HIV, including patient adherence to the complex daily regimens and the inability of current formulations to target viral sanctuaries. Introduction of nanoformulated antiretroviral therapy (ART) is a promising alternative to tackle these challenges. Our laboratory has been focusing on developing long-acting (LA) nanoformulated antiretrovirals and has succeeded in developing LA integrase inhibitors. However, challenges for this approach extend to a range of short-acting hydrophilic …

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 …

Development Of Macromolecular Prodrug Conjugates For The Treatment Of Inflammatory Diseases, Gang Zhao

Theses & Dissertations

Inflammation is the complex biological response to the stimuli triggered by various factors like pathogens, damaged cells, or irritants. Constant uncontrolled acute inflammation may become chronic conditions, leading to significant tissue damage, contributing to a series of chronic inflammatory diseases. Our lab has been working on the different types of inflammatory diseases and has developed multiple macromolecular prodrug conjugates for the better therapeutic efficacy and reduced toxicity. The general approach we have taken is to incorporate small molecules containing monomers into water-soluble and biocompatible polymers, such as N-(2-Hydroxypropyl) methacrylamide (HPMA) copolymers. The superior and the sustained efficacy of those macromolecular …

Ethnic And Demographic Differences In Colectomy Rates And Timing For Ulcerative Colitis: 2007-2014, Daniel Bodek, Alana Persaud, Brian Blair, Ahlawat Sushil

Rowan-Virtua Research Day

Ulcerative Colitis (UC) is a chronic inflammatory disease of the bowel, with one third of patients requiring a colectomy for fulminant disease and tissue dysplasia. In 2007, infliximab was approved for induction and maintenance of remission in UC, with some evidence to suggest a potential reduction in colectomies. The aim of this study is to examine relative colectomy rates for UC among different ethnicities from 2007 to 2014 in order to evaluate for development of new trends or disparities.

Discrepancies in colectomy rates and timing are seen in our models which mirror closely findings in a prior study from 1999-2003 …

Integration Of Native American Medicinal Plants Into The Heber W. Youngken Jr. Garden, Emily Lyn Murray

Senior Honors Projects

Healthcare among Native American tribes was focused on all aspects of a patient’s life, such as physical, spiritual, and environmental elements. Healthy outcomes were obtained by maintaining a balance among all of these components. This “bio-psycho-socio-spiritual” approach to healthcare was thought to not only play a role in the health of a certain individual, but the health of the tribe as a whole. An illness was not only precipitated by a physical source, but by an imbalance of these components. Medicinal plants served as an integral role in direct physical healing, as well as an important element for the execution …

© 2019, Mary Ann Liebert, Inc., publishers 2019. Purpose: Cannabidiol (CBD), active component of plant Cannabis sativa, has anti-inflammatory properties that could potentially help treat diabetic retinopathy-induced pain and inflammation. However, CBD is a lipophilic molecule making its topical delivery to back of the eye challenging. This study aims at improving ocular penetration of CBD by means of analog derivatization. Methods: Analogs were designed using various ligands, such as amino acids (AAs) and dicarboxylic acids (DCAs) and their combinations. Select analogs were screened in vitro with respect to their stability in ocular tissue homogenates. Based on in vitro stability, analogs …

Δ9-Tetrahydrocannabinol Leads To Endoplasmic Reticulum Stress And Mitochondrial Dysfunction In Human Bewo Trophoblasts., Tina Lojpur, Zachary Easton, Sergio Raez-Villanueva, Steven Laviolette, Alison C Holloway, Daniel B Hardy

Physiology and Pharmacology Publications

While studies have demonstrated that the main psychoactive component of cannabis, Δ9-tetrahydrocannabinol (Δ9-THC) alone induces placental insufficiency and fetal growth restriction, the underlying mechanisms remain elusive. Given that both (i) endoplasmic reticulum (ER) stress in pregnancy and (ii) gestational exposure to Δ9-THC leads to placental deficiency, we hypothesized that Δ9-THC may directly induce placental ER stress, influencing trophoblast gene expression and mitochondrial function. BeWo human trophoblast cells treated with Δ9-THC (3-30 μM) led to a dose-dependent increase in all ER stress markers and CHOP; these effects could be blocked with CB1R/CB2R antagonists. Moreover, expression of ER stress-sensitive genes ERRγ, VEGFA, …

Effects Of Renal Ischemia-Reperfusion Injury On Cytochrome P450 Activity, Milleah Sawtelle

Senior Honors Projects

Approximately 2 million people worldwide and more than 670,000 Americans are affected by end-stage renal diseases (ESRD). The current standard of care for ESRD is kidney transplantation. However, the surgical procedure of kidney transplantation inherently involves ischemia, which interrupts blood flow and reduces oxygen, during kidney graft preservation. The ischemic period is followed by reperfusion (the restoration of blood flow to the transplanted graft), resulting in varying degrees of ischemia and reperfusion (I/R) injury. I/R injury is a leading cause of both organ dysfunction and graft failure. Furthermore, kidney I/R injury has been shown to cause remote organ damage, especially …

Identification Of Molecules By Spectral Imaging, Qamar Alshammari

Pharmaceutical Sciences (MS) Theses

Spectral imaging is a powerful technique which uses the wavelength to identify/quantify the exact location and amount of the molecules. It facilitates the identification of materials and studying their properties through analyzing the way they interact with light. The study of light interaction with elements is called spectroscopy; spectroscopy examines how light behaves in the target and recognizes materials based on their spectral signatures. Spectral signatures can be compared to fingerprints which can be used to identify a person; spectral signatures can be used to identify materials. Therefore, we hypothesize that identifying the exact location and quantity of molecules present …
