Heat Shock Factor Gains Access To The Yeast Hsc82 Promoter Independently Of Other Sequence-Specific Factors And Antagonizes Nucleosomal Repression Of Basal And Induced Transcription, Alexander M. Erkine, C. C. Adams, T. Diken, D. S. Gross

Scholarship and Professional Work – COPHS

Transcription in eukaryotic cells occurs in the context of chromatin. Binding of sequence-specific regulatory factors must contend with the presence of nucleosomes for establishment of a committed preinitiation complex. Here we demonstrate that the high-affinity binding site for heat shock transcription factor (HSF) is occupied independently of other cis-regulatory elements and is critically required for preventing nucleosomal assembly over the yeast HSC82 core promoter under both noninducing (basal) and inducing conditions. Chromosomal mutation of this sequence, termed HSE1, erases the HSF footprint and abolishes both transcription and in vivo occupancy of the TATA box. Moreover, it dramatically reduces promoter chromatin …

Synthesis And Evaluation Of Cocaine Analogs For Activity As Cocaine Antagonists And Synthesis Of Novel Prodrugs With Antiarthritic Potential, Bonnie Lisa Barr

MUSC Theses and Dissertations

As a follow up to interest in a new class of agents that have potential for the treatment of arthritic conditions, two series of cocaine derivatives were synthesized. Specifically, an N-alkyl series consisting of the ethyl, n-propyl, isopropyl, n-butyl and benzyl norcocaine derivatives and an N-acyl series consisting of the acetyl, propionyl, butyryl, and benzoyl norcocaine derivatives were synthesized. The structures of these compounds were verified using GC/MS, 1H NMR, and FT-IR with support from elemental analysis. Evaluation of the effect of these cocaine analogs on the inhibition of dopamine uptake represented the biological focus of this project. Each of …

What Is The Risk Of Teratogenicity With The Use Of Selective Serotonin Reuptake Inhibitors During Pregnancy?, Michael Z. Wincor, Mary Gutierrez, Ann Nguyen

Pharmacy Faculty Articles and Research

"The lifetime prevalence of major depressive disorder in women is 10 to 25%, with an average age of onset in the mid-20s.1 Over the nine years that the selective serotonin reuptake inhibitors (SSRis) have been available, for many prescribers, they have become first-line agents in the treatment of depression. In addition, sorne of them are also being used in the treatment of obsessive- compulsive disorder and panic disorder. In light of these facts, itis not unlikely that women of childbearing age would be treated with one of the SSRis. In considering the risks of exposing a fetus to an SSRI, …

Ls There Any Risk Of A Withdrawal Syndrome Associated With Abrupt Discontinuation Of Selective Serotonin Reuptake Inhibitors?, Rene A. Endow, Mary Gutierrez, Michael Z. Wincor

Pharmacy Faculty Articles and Research

"With the availability of the newer selective serotonin reuptake inhibitors (SSRis), concern over a 'cholinergie rebound' seemed unnecessary since these agents demonstrate little or no anticholinergic activity. However, a review of the literature indicates that there may be other withdrawal symptoms associated with discontinuation of the SSRis. The time course and, perhaps to a lesser extent, the frequency of these symptoms appear to be correlated with the elimination half-lives of the agents."

Pharmacokinetics And Pharmacodynamics Of Ethanol In Healthy Volunteers: Effects Of Input-Rate And Degree Of Ethanol Exposure On Subjective And Objective Measures Of Impairment, Vijay A. Ramchandani

Theses and Dissertations

The goal of this project was to investigate the effect of input-rate (oral and intravenous) and degree of exposure on the pharmacokinetics of ethanol and on subjective and objective measures of impairment, as well as on the development of acute tolerance to the effects of ethanol in young, healthy volunteers.

The primary objective of this research was to test the following hypotheses: 1) the rate and degree of ethanol exposure (oral and intravenous) in normal healthy males and females affect the pharrnacokinetics (PK) and pharmacodynarnics (PD) of ethanol in a non-linear fashion; 2) the EEG changes after ethanol administration correlate …

Evaluation Of Cannabinoid Receptor Interaction Of Anandamide, The Endogenous Cannabinoid Receptor Ligand, Irma Bateman Adams

Theses and Dissertations

Recent evidence implicates anandamide as the endogenous ligand for the cannabinoid receptor. One purpose of this study was to determine the structural requirements for anandamide's receptor interaction and the influence of phenylmethylsulfonyl fluoride (PMSF), an enzyme inhibitor, on receptor affinity. A second objective was evaluation of the correlation between affinities of the analogs and in vivo pharmacological activities. The ability of anandamide and analogs to displace [3H]- CP 55,940 was determined by a filtration assay. Displacement curves for anandamide in the presence of PMSF produced a Ki of 89 ± 10 nM; without PMSF the Ki increased to 5400 ± …

Physical And Chemical Stability Of Spray Dried Sugars And Protein-Sugar Molecuiar Mixtures For Inhalation, Venkatesh Naini

Theses and Dissertations

The feasibility of producing inhalable microparticles of sugars and protein-sugar molecular mixtures using spray drying was investigated as an alternative to conventional micronization techniques. Four sugars; lactose (L), trehalose (T), sucrose (S) and mannitol (M) were spray dried using a commercial bench-top spray dryer and their physicochemical stability, with respect to particle size, moisture uptake and crystallinity changes, investigated after storage at 23%, 52%, 75% and 93% relative humidity (RH) and 25 °C for 30 days. Two crystalline size fractions (“coarse” = 125-212 μm and “fine” = 44-74 μm) of each sugar, were also characterized, as possible replacements for lactose …

The Practicality Of Pre-Doctoral Prescription Training For Psychologists: A Survey Of Directors Of Clinical Training, Garret D. Evans

All-Inclusive List of Electronic Theses and Dissertations

The Directors of Clinical Training (DCTs) at the nation's 164 APA-accredited clinical psychology programs iii were surveyed regarding their attitudes toward the hypothetical implementation of a sample pre-doctoral prescription training model created by the Ad Hoc Task Force on Psychopharmacology of the APA (1992). A 60% return rate (99 questionnaires) was achieved. Results suggest that the majority of DCTs (62%) remain equivocal regarding the implementation of such training at their program. A majority (62%) identify post-doctoral specialization as the preferred method of prescription training. DCTs' perceptions of benefits stemming from pre-doctoral prescription training served as the most potent predictor of …

Differential Modulation Of Human Glutamate Transporter Subtypes By Arachidonic Acid, Noa Zerangue, Jeffrey L. Arriza, Susan G. Amara, Michael Kavanaugh

Biomedical and Pharmaceutical Sciences Faculty Publications

Arachidonic acid has been proposed to be a messenger molecule released following synaptic activation of glutamate receptors and during ischemia. Here we demonstrate that micromolar levels of arachidonic acid inhibit glutamate uptake mediated by EAAT1, a human excitatory amino acid transporter widely expressed in brain and cerebellum, by reducing the maximal transport rate approximately 30%. In contrast, arachidonic acid increased transport mediated by EAAT2, a subtype abundantly expressed in forebrain and midbrain, by causing the apparent affinity for glutamate to increase more than 2-fold. The results demonstrate that the response of different glutamate transporter subtypes to arachidonic acid could influence …

A Family Of Putative Receptor-Adenylate Cyclases From Leishmania Donovani, Marco A. Sanchez, David Zeoli, Elizabeth M. Klamo, Michael Kavanaugh, Scott M. Landfear

Biomedical and Pharmaceutical Sciences Faculty Publications

Leishmania parasites are exposed to pronounced changes in their environment during their life cycle as they migrate from the sandfly midgut to the insect proboscis and then into the phagolysosomes of the vertebrate macrophages. The developmental transformations that produce each life cycle stage of the parasite may be signaled in part by binding of environmental ligands to receptors which mediate transduction of extracellular signals. We have identified a family of five clustered genes in Leishmania donovani which may encode signal transduction receptors. The coding regions of two of these genes, designated rac-A and rac-B, have been sequenced and shown …

Constitutive Ion Fluxes And Substrate Binding Domains Of Human Glutamate Transporters, Robert J. Vandenberg, Jeffrey L. Arriza, Susan G. Amara, Michael Kavanaugh

Biomedical and Pharmaceutical Sciences Faculty Publications

Application of L-glutamate activates ionic currents in voltage-clamped Xenopus oocytes expressing cloned human excitatory amino acid transporters (EAATs). However, even in the absence of L-glutamate, the membrane conductance of oocytes expressing EAAT1 was significantly increased relative to oocytes expressing EAAT2 or control oocytes. Whereas transport mediated by EAAT2 is blocked by the non-transported competitive glutamate analog kainate (K = 14 μM), EAAT1 is relatively insensitive (K > 3 mM). Substitution of a block of 76 residues from EAAT2 into EAAT1, in which 18 residues varied from EAAT1, conferred high affinity kainate binding to EAAT1, and application of kainate to …

Effect Of Ibogaine On Morphine: Induced Modifications Of Palatability, Hardy Joseph Rideout

Theses and Dissertations (Comprehensive)

The ability of the potential anti-addictive agent ibogaine to module the morphine-induced modification of quinine and sucrose palatability was assessed utilizing the taste reactivity test. Ibogaine (40mg/kg) was administered 24 hr prior to an injection of morphine (2 mg/kg), followed 30 min later by a 5 min intraoral infusion of 0.05% quinine solution (Experiment 1) or 10% sucrose solution (Experiment 2). Treatment with morphine enhanced the palatability of both quinine and sucrose solution. Morphine reduced the aversiveness of quinine solution during the 5 min of testing and enhanced ingestive responding to sucrose solution, however, only during min 1 of the …

The Biological Speciation And Toxicokinetics Of Aluminum, Emily Devoto, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

This review discusses recent literature on the chemical and physiological factors that influence the absorption, distribution, and excretion of aluminum in mammals, with particular regard to gastrointestinal absorption and speciation in plasma. Humans encounter aluminum, a ubiquitous yet highly insoluble element in most forms, in foods, drinking water, and pharmaceuticals. Exposure also occurs by inhalation of dust and aerosols, particularly in occupational settings. Absorption from the gut depends largely on pH and the presence of complexing ligands, particularly carboxylic acids, with which the metal can form absorbable neutral aluminum species. Uremic animals and humans experience higher than normal body burdens …

Cloning Of The Cellular Receptor For Amphotropic Murine Retroviruses Reveals Homology To That For Gibbon Ape Leukemia Virus, Daniel G. Miller, Robert H. Edwards, A. Dusty Miller

Biomedical and Pharmaceutical Sciences Faculty Publications

The host and tissue specificity of retrovirus infection is largely determined by specific cellular receptors that mediate virus entry. Genes encoding these receptors are widely distributed in the genome, and the receptors identified to date show no sequence similarity. We have identified the cellular receptor for amphotropic murine retroviruses, Ram-1, by screening a rat cDNA expression library introduced into amphotropic virus-resistant hamster cells. The 656-amino acid receptor is homologous to the gibbon ape leukemia virus receptor at both hydrophobic termini but is highly divergent in the central hydrophilic region. Both receptors appear to be integral membrane proteins having multiple membrane-spanning …
