Thermostability Of The Coating, Antigen And Immunostimulator In An Adjuvanted Oral Capsule Vaccine Formulation, Stephanie Longet, Vincenzo Aversa, Daire O'Donnell, Joshua Tobias, Monica Rosa, Jan Holmgren, Ivan Coulter, Ed Lavelle

Articles

Oral vaccines present an attractive alternative to injectable vaccines for enteric diseases due to ease of delivery and the induction of intestinal immunity at the site of infection. However, susceptibility to gastrointestinal proteolysis, limited transepithelial uptake and a lack of clinically acceptable adjuvants present significant challenges. A further challenge to mass vaccination in developing countries is the very expensive requirement to maintain the cold chain. We recently described the effectiveness of a Single Multiple Pill® (SmPill®) adjuvanted capsule approach to enhance the effectiveness of a candidate enterotoxigenic Escherichia coli (ETEC) oral vaccine. Here it was demonstrated that this delivery system …

Molecular Characterization Of The Opioid Receptors: Design, Development, And Preclinical Evaluation Of Salvinorin A-Based Molecular Probes., Adam Keasling

Electronic Theses and Dissertations

The field of salvinorin chemistry represents a novel and emerging field of opioid research. The novelty is derived from the lead pharmacophore: salvinorin A — a neoclerodane diterpenoid natural product isolated from Salvia divinorum. Salvinorin A represents a pharmacologically unique compound in that it is the first known non-nitrogenous KOR subtype-selective agonist, exhibits a comparatively safe physiological profile with no reports of toxicological effects in clinical trials, and, most importantly, has a steadily growing body of literature indicating potentially useful clinical applications (e.g. antinociceptive, anti-addictive, antipruritic, neuroprotective, etc.). This has encouraged the development of analogues as essential molecular probes to …

Development Of Phenotypic Drug Discovery Models For Tropical Parasitic Diseases, Surendra Kumar Jain

Electronic Theses and Dissertations

Malaria and visceral leishmaniasis are major killer parasitic diseases. These diseases though occur primarily in tropical countries; economic burden and overall health impacts of malaria and leishmaniasis are global. The emergence of drug-resistant and more-virulent strains of the pathogens has further amplified the problems. New drug discovery approaches primarily rely on in vitro and in vivo models of the disease. The pathogens causing leishmaniasis and malaria are intracellular. Leishmania parasite grows as amastigotes in macrophages cells, and malaria parasite grows within the hepatocytes or erythrocytes. The intracellular forms of the pathogens are responsible for the pathophysiology of the diseases. New …

Phytochemical Investigation Of Psychoactive Medicinal Plants For The Treatment Of Neurological Disorders, Vedanjali Gogineni

Electronic Theses and Dissertations

Neurological disorders include disorders such as migraine, tension-type headaches, Parkinson’s disease (PD), epilepsy, dementia, and Alzheimer’s disease (AD). Globally, PD is the second most comneurodegenerative disorder following AD. In developed countries, PD affects 1% of all population over 60 years of age. The prevalence of PD is increasing over the years and is expected to double by 2030. It is proposed that combination of dopaminergic drugs with monoamine oxidase B (MAO-B) inhibitors, anticholinergics, catechol-O-methyl transferase inhibitors, and other non-dopaminergic drugs can better alleviate levodopa-induced motor complications along with better control of motor symptoms. MAO-B inhibitors play a significant role in …

Study Of Molecular Interactions Of Glycosaminoglycans And Glycosaminoglycan Mimetics With Their Protein Targets, Daniel K. Afosah

Theses and Dissertations

Glycosaminoglycans (GAGs) are complex linear chain carbohydrate molecules found on virtually all animal cell surfaces. Owing to their negatively charged nature, GAGs interact with a number of different proteins. Thus, although they have great potential as therapeutic agents, their apparent promiscuous interactions increase their side effect risk. GAG mimetics, including GAG oligosaccharides and non-saccharide GAG mimetics (NSGMs) are viable approaches to address this. This work discusses sulfated benzofuran thrombin inhibitors with submaximal protease inhibition, sulfated diflavonoid inhibitors of plasmin and GAG oligosaccharides with selectivity for human neutrophil elastase (HNE).

Anticoagulants are very important for the treatment of thrombotic diseases. The …

Department of Food Science and Technology: Faculty Publications

In December 2016, a panel of experts in microbiology, nutrition and clinical research was convened by the International Scientific Association for Probiotics and Prebiotics to review the definition and scope of prebiotics. Consistent with the original embodiment of prebiotics, but aware of the latest scientific and clinical developments, the panel updated the definition of a prebiotic: a substrate that is selectively utilized by host microorganisms conferring a health benefit. This definition expands the concept of prebiotics to possibly include non-carbohydrate substances, applications to body sites other than the gastrointestinal tract, and diverse categories other than food. The requirement for selective …

Applying Clinical Guidelines To Curtail Opioid Overprescribing In Primary Care, Glenda Leflore

Walden Dissertations and Doctoral Studies

The purpose of this scholarly project was to evaluate an evidence-based quality improvement program implemented in 2016 in a clinical practice setting to curtail overprescribing of opioids for noncancer pain management. In 2001, the National Pharmaceutical Council and The Joint Commission on Accreditation and Hospital Accreditation initiated a standard of practice for opioid use in noncancer pain management that resulted in opioid overprescribing and a 200% increase in opioid-related deaths and incalculable societal costs. Primary care providers including nurse practitioners issue the greatest number of opioid prescriptions; therefore, to address the problem of opioid overprescribing, the 2016 Centers for Disease …

Infusion Of Essentail Oils In Agarose Gels To Create Antimicrobial Surfaces, Simran Guron

Honors College Theses

The current use of antibiotics is very excessive in multiple settings, from treating patients to being present in cleaning products. This overuse of antibiotics is resulting in multiple consequences, ranging from having a negative impact on human health to breeding antibiotic-resistant strains of microorganisms. Antimicrobial surfaces are useful today to aid in sterilization, especially in the medical setting. This would help prevent the spread of infection of microorganisms in these settings. In our research, agarose acts as the antimicrobial surface and essential oils would act as the solution incorporated into the surface that has the antimicrobial properties. Agarose is a …

A Case Of Amlodipine Overdose: Role Of High Dose Insulin Therapy, Kelvin Tran, Thinh Tang, Tarris Webber, Paul J. Kalekas, Quang T. Nguyen

College of Osteopathic Medicine (TUN) Publications and Research

Introduction: High dose insulin (HDI) therapy, defined as > 0.5 units/kg/hour, has been postulated to improve hemodynamics in both calcium channel blocker (CCB) and beta-blocker overdose. Proposed benefits of HDI include coronary and systemic vasodilation due to enhancement of nitric oxide synthase activity leading to improved contractility and decreased systemic vascular resistance, respectively. HDI also directly improves cardiac contractility by increasing glucose uptake and improving calcium handling within cardiac cells. We present a case of a patient with amlodipine overdose and her response to HDI therapy.

Case presentation: A 52 year old female presented with amlodipine overdose after suicide attempt leading …

Synthesis Of Ag10 Analogs And Optimization Of Ttr Ligands For Half-Life Enhancement (Tlhe) Of Peptides, Raghavendra Jampala

University of the Pacific Theses and Dissertations

The misassembly of soluble proteins into toxic aggregates, including amyloid fibrils, underlies a large number of human degenerative diseases. Cardiac amyloidosis, which is most commonly, caused by aggregation of Immunoglobulin (Ig) light chains or transthyretin (TTR) in the cardiac muscle, represent an important and often underdiagnosed cause of heart failure. TTR-mediated amyloid cardiomyopathies are chronic and progressive conditions that lead to arrhythmias, biventricular heart failure, and death. As no Food and Drug Administration-approved drugs are currently available for treatment of these diseases, the development of therapeutic agents that prevent TTR-mediated cardiotoxicity is desired. AG10 is a potent and selective kinetic …

Chemoselective And Stereoselective Exploration Of The Chemical Reactivity Space Of Castagnoli-Cushman-Derived Allylic Lactamoyl Esters: Application To The Synthesis Of Aza-Polycyclic Architectures, Brandon Joseph Mansker

All Master's Theses

The synthesis and evaluation of structure-activity relationships of saturated nitrogen heterocycles is the focal point of various pharmaceutical companies thanks to the high biological activity of previously isolated azacycles. Here, we describe an operationally simple and highly efficient approach to macrocyclic lactams bearing vicinal stereocenters and a challenging cycloalkyne motif. The outcomes are achieved through a novel [4 + 2] cycloaddition reaction between an N-iodoarylated-1,3-azadiene and cyclic anhydrides, followed by interception of the cycloadducts in cross-coupling manifolds (e.g., Sonogashira coupling) and concomitant lithiation-cyclization of the tethered alkyne. An unprecedented example of a hydroamino alkylation that is transition …
