Wayne State University Associated BioMed Central Scholarship

Abstract

Background

This paper assess the relationship between the quantity of three anti-seizure medications in hair and the color of the analyzed hair, while controlling for the effects of dose, dose duration, and patient age for 140 clinical patients undergoing anti-seizure therapy. Three drugs are assessed: carbamazepine (40 patients), valproic acid (40 patients), and phenytoin (60 patients). The relationship between hair assay results, hair color, dose, dose duration, and age is modeled using an analysis of covariance. The covariance model posits the hair assay results as the dependent variable, the hair color as the qualitative categorical independent variable, and dose, …

Guanylyl Cyclase C (Gc-C) Inhibits Human Colon Carcinoma Cell Growth, Giovanni Mario Pitari

Department of Pharmacology and Experimental Therapeutics Faculty Papers

This is the presentation given for the 2001 Presidential Trainee Young Investigator Award, American Society for Clinical Pharmacology and Therapeutics. An abstract of the presentation has been published in Clin. Pharmacol. Ther., 69(2):P62, 2001. The presentation illustrates the role of the intestinal GC-C receptor as a negative regulator of cell proliferation and cell cycle kinetics in colorectal cancer. It suggests that paracrine GC-C hormones guanylin/uroguanylin are physiological inducers of the proliferation-to-differentiation transition along the intestinal crypt-villus axis. Importantly, the bacterial enterotoxin ST, a potent exogenous GC-C agonist, is offered as a potential cytostatic agent for the prevention and treatment of …

Ecuador: Use Commercial Marketing To Increase Sustainability, Frontiers In Reproductive Health

Reproductive Health

Many nongovernmental organizations sell contraceptives through retail outlets to generate income and expand access to these products. In 1998 Centro Médico de Orientación y Planifación Familiar (CEMOPLAF) employed 25 sales agents in 14 cities throughout Ecuador. These agents sold products, including contraceptive methods and home pregnancy tests, to pharmacies, physicians, other distributors, and nontraditional outlets. Contraceptive sales were CEMOPLAF’s largest source of revenue in 1997. Sales had grown rapidly during 1996–97, but CEMOPLAF managers did not know whether product sales were profitable. With support from the Population Council and Family Health International, CEMOPLAF made a detailed analysis of product sales …

Analysis Of Loratadine By Potentiometry And Reverse-Phase High Performance Liquid Chromatography, Kian Yong Puen

Student Works (2000-2009)

A non-aqueous titration method was developed to assay Loratadine bulk active and a High Performance Liquid Chromatography (HPLC) method was developed to determine Loratadine's manufacturing impurity. The HPLC method was also suitable for simultaneously assay and related substance determination of Loratadine pharmaceutical preparations. In the tritation method, glacial acetic acid was chosen as an amphiprotic solvent. Loratadine ionised in glacial acetic acid; the conjugated base of acetic acid (Ac·), was then titrated with standardised perchloric acid. The method was validated found to be precise, linear and robust. Reverse-phase HPLC method using a Novapak Cl8 column with a CH3CN: I0mM K2HPO4 …

Stereospecific Pharmacokinetics And Pharmacodynamics Of Beta-Adrenergic Blockers In Humans, Reza Mehvar, Dion R. Brocks

Pharmacy Faculty Articles and Research

The beta-blockers comprise a group of drugs that are mostly used to treat cardiovascular disorders such as hypertension, cardiac arrhythmia, or ischemic heart disease. Each of these drugs possesses at least one chiral center, and an inherent high degree of enantioselectivity in binding to the b-adrenergic receptor. For beta-blockers with a single chiral center, the (-) enantiomer possesses much greater affinity for binding to the b-adrenergic receptors than antipode. The enantiomers of some of these drugs possess other effects, such as antagonism at alpha-adrenergic receptors or Class III antiarrhythmic activity. However, these effects generally display a lower level of stereoselectivity …

Receptor Number And Caveolar Co-Localization Determine Receptor Coupling Efficiency To Adenylyl Cyclase, Rennolds S. Ostrom, Caroline Gregorian, Ryan M. Drenan, Yang Xiang, John W. Regan, Paul A. Insel

Pharmacy Faculty Articles and Research

Recent evidence suggests that many signaling molecules localize in microdomains of the plasma membrane, particularly caveolae. In this study, overexpression of adenylyl cyclase was used as a functional probe of G protein-coupled receptor (GPCR) compartmentation. We found that three endogenous receptors in neonatal rat cardiomyocytes couple with different levels of efficiency to the activation of adenylyl cyclase type 6 (AC6), which localizes to caveolin-rich membrane fractions. Overexpression of AC6 enhanced the maximal cAMP response to β1-adrenergic receptor (β1AR)-selective activation 3.7-fold, to β2AR-selective activation only 1.6-fold and to prostaglandin E2 (PGE2) not at all. Therefore, the rank order of efficacy in …

Ryanodine Receptor Adaptation, Michael Fill, A. Zahradníková, Carlos A. Villalba-Galea, I. Zahradník, A. L. Escobar, S. Györke

School of Pharmacy Faculty Articles

In the heart, depolarization during the action potential activates voltage-dependent Ca²⁺ channels that mediate a small, localized Ca²⁺ influx (I_Ca). This small Ca²⁺ signal activates specialized Ca²⁺ release channels, the ryanodine receptors (RyRs), in the sarcoplasmic reticulum (SR). This process is called Ca²⁺-induced Ca²⁺ release (CICR). Intuitively, the CICR process should be self-regenerating because the Ca²⁺ released from the SR should feedback and activate further SR Ca²⁺ release. However, the CICR process is precisely controlled in the heart and, consequently, some sort of negative control mechanism(s) must exist to …

Hybridization Of Dna By Sequential Immobilization Of Oligonucleotides At The Air-Water Interface, Murali Sastry, Vidya Ramakrishnan, Mrunalini Pattarkine, Anand Gole, K. N. Ganesh

Faculty Works

The hybridization of DNA by sequential electrostatic and hydrogen-bonding immobilization of single-stranded complementary oligonucleotides at the air-water interface with cationic Langmuir monolayers is demonstrated. The complexation of the single-stranded DNA molecules with octadecylamine (ODA) Langmuir monolayers was followed in time by monitoring the pressure-area isotherms. A large (and slow) expansion of the ODA monolayer was observed during each stage of complexation in the following sequence: primary single-stranded DNA followed by complementary single-stranded DNA followed by the intercalator, ethidium bromide. Langmuir-Blodgett (LB) films of the ODA-DNA complex were formed on different substrates and characterized using quartz-crystal microgravimetry (QCM), Fourier transform infrared …

The Toxicology Of Aluminum In The Brain: A Review, Robert A. Yokel

Pharmaceutical Sciences Faculty Publications

Aluminum is environmentally ubiquitous, providing human exposure. Usual human exposure is primarily dietary. The potential for significant Al absorption from the nasal cavity and direct distribution into the brain should be further investigated. Decreased renal function increases human risk of Al-induced accumulation and toxicity. Brain Al entry from blood may involve transferrin-receptor mediated endocytosis and a more rapid process transporting small molecular weight Al species. There appears to be Al efflux from the brain, probably as Al citrate. There is prolonged retention of a fraction of Al that enters the brain, suggesting the potential for accumulation with repeated exposure. Al …

Ouabain Interaction With Cardiac Na+/K+-Atpase Initiates Signal Cascades Independent Of Changes In Intracellular Na+ And Ca2+, Jiang Liu, Jiang Tian, Michael Haas, Joseph I. Shapiro, Amir Askari, Zijian Xie

Pharmaceutical Science and Research

We have shown previously that partial inhibition of the cardiac myocyte Na⁺/K⁺-ATPase activates signal pathways that regulate myocyte growth and growth-related genes and that increases in intracellular Ca²⁺ concentration ([Ca²⁺]i) and reactive oxygen species (ROS) are two essential second messengers within these pathways. The aim of this work was to explore the relation between [Ca²⁺]i and ROS. When myocytes were in a Ca²⁺-free medium, ouabain caused no change in [Ca²⁺]i, but it increased ROS as it did when the cells were in …

Sequential Group Trial To Determine Gastrointestinal Site Of Absorption And Systemic Exposure Of Azathioprine, Jane M. Gervasio, Rex O. Brown, John Lima, M. G. Tabbaa, Thomas Abell, Robert Werkman, Lynda J. Haberer, Lawrence J. Hak

Scholarship and Professional Work – COPHS

Azathioprine (AZA) is used in the treatment of patients with refractory inflammatory bowel disease; however, its use is limited because of systemic toxicity associated with long-term use. Ileocecal delivery of AZA might be advantageous if local intestinal therapeutic effects could be provided with decreased systemic side effects. Decreased cecal systemic absorption would allow higher dosages of AZA to be administered. A two-phase study was performed to compare the systemic exposure of AZA and 6-mercaptopurine (6-MP) following administration of AZA into the stomach, jejunum, and cecum and to compare the systemic exposure to AZA and 6-MP following administration of three different …

Use Of Lobeline Compounds In The Treatment Of Central Nervous System Diseases And Pathologies, Peter A. Crooks, Linda P. Dwoskin

Pharmaceutical Sciences Faculty Patents

Lobeline and nicotine evoke [³H]overflow from rat striatal slices preloaded with [³H]dopamine ([³H]DA). The lobeline-evoked overflow is calcium-independent and not antagonized by mecamylamine, suggesting a mechanism of action other than the stimulation of nicotinic receptors. Whereas nicotine stimulates nicotinic receptors, lobeline inhibits [³H]DA uptake into synaptic vesicles and striatal synaptosomes. The results suggest that different mechanisms are responsible for the increase in striatal DA release evoked by lobeline and nicotine. [³H]-Dihydrotetrabenazine [³H]DTBZ), used routinely to probe a high-affinity binding site-on the vesicular monoamine transporter (VMAT2) binds to vesicle …

Angiotensin Ii Promotes Atherosclerotic Lesions And Aneurysms In Apolipoprotein E-Deficient Mice, Alan Daugherty, Michael W. Manning, Lisa A. Cassis

Gill Heart & Vascular Institute Faculty Publications

Increased plasma concentrations of angiotension II (Ang II) have been implicated in atherogenesis. To examine this relationship directly, we infused Ang II or vehicle for 1 month via osmotic minipumps into mature apoE^–/– mice. These doses of Ang II did not alter arterial blood pressure, body weight, serum cholesterol concentrations, or distribution of lipoprotein cholesterol. However, Ang II infusions promoted an increased severity of aortic atherosclerotic lesions. These Ang II–induced lesions were predominantly lipid-laden macrophages and lymphocytes; moreover, Ang II promoted a marked increase in the number of macrophages present in the adventitial tissue underlying lesions. Unexpectedly, pronounced abdominal …
