Investigators examined patients' use, knowledge and perceptions of pharmacy compounding at an independent compounding pharmacy in Mandeville, Louisiana. Data were collected using a self-administered survey that patients could complete in hard-copy in the pharmacy or at home, or online using Qualtrics. Investigators found that, in some instances, patients who use compounded medications, or have a member of their household who uses compounded medications, may be more knowledgeable or have more positive perceptions of compounded medications. However, patients who did not have experience with compounds were not unknowledgeable about the practice and did not report any negative perceptions of compounding. These …

Evaluation And Enhancement Of Physical Stability Of Amorphous Solid Dispersions, Xin Feng

Electronic Theses and Dissertations

A major concern during formulation development has been to enhance the dissolution rate and bioavailability of poorly water-soluble drugs.[1],[2] The amorphous forms of APIs have attracted considerable attention as the amorphous forms tend to exhibit significantly higher levels of supersaturation in aqueous media when compared to the crystalline forms.[3],[4] For drugs which bioavailability is limited by aqueous solubility (biopharmaceutical classification system (BCS) class II drugs), which is a significant number of recently discovered drug candidates, the improved solubility may lead to enhanced bioavailability.[5-7] Oral absorption of APIs depends on two broad, but crucial, events, namely drug solubilization and gastrointestinal permeation.[8] …

Social Problems, Biomedical Answers? How Causes Of Social Problems Affect Choice Of Solutions, Bianca C. Dreyer

Theses and Dissertations (Comprehensive)

With rapid advances in behavioural genetics, scientists are identifying an increasing array of genetic influences on human behaviour. Public misconceptions about the function of genes often lead to the oversimplification of the role of genes in behaviour (Dar-Nimrod & Heine, 2011). To date, no study has systematically investigated whether simply learning about genetic causes of behaviour affects people’s preferred solutions to problematic behaviours. The present research program includes three studies that were designed to examine the psychological effects of exposure to genetic etiology for problematic behaviour, in particular aggression, and investigated how this information influences endorsement of solutions, rating of …

Wake Me When It's Over- Bacterial Toxin-Antitoxin Proteins And Induced Dormancy, Nathan P. Coussens, Dayle A. Daines

Biological Sciences Faculty Publications

Toxin-antitoxin systems are encoded by bacteria and archaea to enable an immediate response to environmental stresses, including antibiotics and the host immune response. During normal conditions, the antitoxin components prevent toxins from interfering with metabolism and arresting growth; however, toxin activation enables microbes to remain dormant through unfavorable conditions that might continue over millions of years. Intense investigations have revealed a multitude of mechanisms for both regulation and activation of toxin-antitoxin systems, which are abundant in pathogenic microorganisms. This minireview provides an overview of the current knowledge regarding type II toxin-antitoxin systems along with their clinical and environmental implications.

Relational Intelligence: A Framework To Enhance Interprofessional Collaborative Care, Elizabeth Ekole

Walden Dissertations and Doctoral Studies

Many studies have reported that the training for practitioners does not stimulate reflexes that contribute to the tenets of teamwork and collaboration. No studies were found to investigate relational intelligence (RQ) in pharmacist-physician relationships as a catalyst for collaborative and hence cost effective quality care. This study addressed the role and potential opportunity to promote RQ as a critical leadership skill in the collaboration between pharmacists and physicians. Using RQ as the conceptual framework, this phenomenological study explored how pharmacists and physicians in a hospital setting perceive RQ as a leadership skill when working collaboratively. A total of 10 participants …

School of Medical Diagnostics & Translational Sciences Publications

In this study, we used extracellular matrix (ECM) gels and human bone allograft as matrix vehicles to deliver the sphingolipid growth factor FTY720 to rodent models of tibial fracture and a critical-sized cranial defect. We show that FTY720 released from injectable ECM gels may accelerate callous formation and resolution and bone volume in a mouse tibial fracture model. We then show that FTY720 binds directly to human trabecular allograft bone and releases over 1 week in vitro. Rat critical-sized cranial defects treated with FTY720-coated grafts show increases in vascularization and bone deposition, with histological and micro-computed topography (microCT) evidence of …

Exploration In The Effectiveness Of Solid Lipid Nanoparticle Formulations In Enhancing Ocular Delivery Of Win 55, 212 In The Management Of Glaucoma, Emily Ann Nesbit

Honors Theses

Glaucoma is a progressive and degenerative ocular disease which, without proper treatment, can result in permanent blindness. Due to a complex organization of lipophilic and hydrophilic ocular membranes, topical delivery of therapeutic agents has also proved to be a challenging task. Cannabinoids, such as Δ9-Tetrahydrocannabinol (THC), have intraocular pressure (IOP) lowering and neuroprotective capabilities. Due to the unfavorable physiochemical characteristics of these molecules, delivery into the eye through a topical route is very difficult. Previous research has shown that prodrug derivatization and formulations such as solid lipid nanoparticles (SLNs) improve the physiochemical characteristics and ocular bioavailability of such molecules. WIN …

Identification Of Inhibitors Of Fxii, Alexandra C. Bensel

Honors Theses

Hereditary angioedema is characterized by recurrent swelling of the extremities, larynx, and gastrointestinal tract. While type I and type II hereditary angioedema result from a C1-inhibitor deficiency, a new variant of the disease, type III hereditary angioedema, was recently discovered in individuals with functioning levels of the C1-inhibitor. Ongoing research has postulated that increased activity of factor XII is responsible for this new form of hereditary angioedema because it causes overproduction of bradykinin. The purpose of the experiment was to identify inhibitors of factor XII. One hundred and seventy six molecules were screened through a dose response using Human Factor …
