The aim of this work is to develop novel formulations based on an In Situ Implant (ISI) systems to provide a modified vaccine release and altered immune response, which could act as a booster administration. This type of system was selected because ISI systems are used for long acting administration of various drugs and ease of administration. A typical ISI system is comprised of hydrophilic organic …

Analysis Of Ligand Bias In Functional Studies Involving The Allosteric Modulation Of G Protein- Coupled Receptors, Frederick J. Ehlert, Michael T. Griffin

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Introduction

The affinity constants of a ligand for active and inactive states of a receptor ultimately determine its capacity to activate downstream signaling events. In this report, we describe a reverse-engineering strategy for estimating these microscopic constants.

Methods

Our approach involves analyzing responses measured downstream in the signaling pathway of a G protein-coupled receptor under conditions of allosteric modulation and reduced receptor expression or partial receptor inactivation. The analysis also yields estimates of the isomerization constant of the unoccupied receptor, the sensitivity constant of the signaling pathway, and the more empirical parameters of the receptor population including the observed affinities …

Assessing The Relationship Between The Blood-Air Partition Coefficient And Fractional Uptake Of Inspired Halothane, Acetone, And Ethanol Vapors In The Airways Of The C57bl/6j Mouse, Joshua Baruch Baldino

Honors Scholar Theses

The following series of studies investigates the elimination and uptake trends of halothane, acetone, and ethanol vapors in the airways of C57BL/6J mice. These vapors were chosen because they span a wide range of solubilities, as indicated by their blood-air partition coefficients, and are not associated with any significant airway metabolism or reactivity with tissue substrates in vivo. Mice were exposed to a homogeneous vapor mixture containing a 1:1:1 ratio of halothane, acetone, and ethanol at relative concentrations of approximately 10 ppm. Exposure studies were performed with mice in two states, conscious and deceased, in order to provide control …

Glioma: A Tale Of Corticosteroids, Thiopurines And Proposed Novel Antiglioma Small Molecules, Amira Ahmed

Theses and Dissertations (ETD)

Glioma is a brain tumor that arises from glial cells or glial progenitor cells, and represents 80% of malignant brain tumor incidence in the United States. Glioblastoma multiforme (GBM) is the most aggressive primary brain tumor malignancy with fewer than 8% of patients with GBM surviving for 3 years. Over the past 10 years, despite improvement in diagnosis and therapies for cancer, the survival rate for high-grade glioma patients remains unchanged. The main focus of this dissertation is to investigate two therapeutic agents that are related to increase tumor resistance or increase secondary tumor incidence, which might play a role …

Preventive Effect Of Non-Mitogenic Acidic Fibroblast Growth Factor On Diabetes-Induced Testicular Cell Death., Melissa Skibba 1990-

Electronic Theses and Dissertations

Fibroblast growth factor (FGF)-1 was found to protect the heart from oxidative damage, but clinically its long-term use was restricted for its undesirable proliferating activity on cells. Thus a cluster of amino acids responsible for the proliferation were deleted in the native FGF-1 to create a non-mitogenic FGF-1 (nmFGF-1). To assess whether nmFGF-1 protects male germ cells from diabetes-induced apoptotic death, the study employed a murine model of diabetes using multiple low-doses of streptozotocin, followed by nmFGF-1 treatment for 6 months. Diabetic mice showed a decrease in testicular weight and an increase in apoptotic cell death. Treatment with nmFGF-1 alleviated …

The Role Of Pesticides In Non-Alcoholic Fatty Liver Disease (Nafld)., Laila Al-Eryani 1986-

Electronic Theses and Dissertations

NAFLD, the most common form of liver disease worldwide, is caused by various factors including industrial chemicals and pesticides exposure. Annually, 5.2 billion pounds of pesticides are used worldwide and can contribute to liver disease, but their role is modestly studied. We hypothesize that pesticides contaminating food supply can worsen diet-induced steatosis via xenobiotic receptor activation. Two human and two rodent databases were utilized and 85% of the 330 chemicals identified associated with NAFLD were pesticides. Eight were selected for evaluating hepatic receptor activation in vitro. The majority including DDT activated hPXR/CAR and mPXR. DDT (100 mg/kg) was studied in …

Neurodegeneration-Associated Instability Of Ribosomal Dna., Justin Lauren Hallgren 1981-

Electronic Theses and Dissertations

Homologous recombination-mediated instability of the repetitively organized ribosomal DNA has been proposed as a mediator of cell senescence in yeast triggering the DNA damage response. High individual variability in the content of human ribosomal DNA suggests that this genomic region remained relatively unstable throughout evolution. Therefore, quantitative real time PCR was used to determine the genomic content of ribosomal DNA in post mortem samples of parietal cortex from 14 young and 9 elderly individuals with no diagnosis of a chronic neurodegenerative/neurological disease. In addition, ribosomal DNA content in that brain region was compared between 10 age-matched control individuals and 10 …

A Survey Of Antimicrobial Stewardship Practices In The Western United States: Successes And Challenges, Gayle Louise Allenback

UNLV Theses, Dissertations, Professional Papers, and Capstones

Antibiotics are one of the most important developments in medicine, and their ability to prevent and control infections has had a major impact in clinical medicine. However, the past three decades have shown an increase in multidrug-resistant organisms (MDROs) in both hospital patients and in the community, decreasing our ability to successfully control infection. Complicating the depletion of effective antimicrobials is the fact that, in the last 10 years, there has also been a decrease in the development of new antibacterial agents. Resistant infections have resulted in increased morbidity and mortality, with a consequential increase in healthcare costs. The utilization …

Investigations Of Novel Mechanisms Of Action For Anti-Bacterial And Anti-Cancer Agent Development, Jenson Verghese

Theses and Dissertations

The development of drugs and therapeutic agents for combating infections and human malignancies continues to be a forefront area in both academic and industrial research. This is driven by the rapid emergence of multi-drug resistant bacterial strains and accumulating mutations in cancer targets that is quickly rendering our current arsenal of drugs ineffective for these therapies. Unless new drugs with novel mechanisms of action are identified and developed at a faster pace, we face a losing battle in managing these diseases. The first part of this work concerns with the natural product Simocyclinone D8 (SD8). Simocyclinone D8 is an angucyclinone …
