DESCRIPTION Neogen Corporation’s Clenbuterol ELISA (Enzyme-Linked ImmunoSorbent Assay) test kit is a qualitative one-step kit designed for use as a screening device for the detection of drugs and/or their metabolites. The kit was designed for screening purposes and is intended for forensic use only. It is recommended that all suspect samples be confirmed by a quantitative method such as gas chromatography/mass spectrometry (GC/MS). ASSAY PRINCIPLES Neogen Corporation’s test kit operates on the basis of competition between the drug or its metabolite in the sample and the drug- enzyme conjugate for a limited number of antibody binding sites. First, the sample or control is added to the microplate. Next, the diluted drug-enzyme conjugate is added and the mixture is incubated at room temperature. During this incubation, the drug in the sample or the drug-enzyme conjugate binds to antibody immobilized in the microplate wells. After incubation, the plate is washed 3 times to remove any unbound sample or drug-enzyme conjugate. The presence of bound drug-enzyme conjugate is recognized by the addition of K-Blue® Substrate (TMB). After a 30 minute substrate incubation, the reaction is halted with the addition of Red Stop Solution.

    !"!#$ CHEMICAL GENETIC INTERROGATION OF NEURAL STEM CELLS: PHENOTYPE AND FUNCTION OF NEUROTRANSMITTER PATHWAYS IN NORMAL AND BRAIN TUMOUR INITIATING NEURAL PRECUSOR CELLS by Phedias Diamandis A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy. Department of Molecular Genetics University of Toronto © Copyright by Phedias Diamandis 2010 Phenotype and Function of Neurotransmitter Pathways in Normal and Brain Tumor Initiating Neural Precursor Cells Phedias Diamandis Doctor of Philosophy Department of Molecular Genetics University of Toronto 2010 &'(!)&*!% The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain brings promise for the treatment of neurological diseases and has yielded new insight into brain cancer. The complete repertoire of signaling pathways that governs these cells however remains largely uncharacterized. This thesis describes how chemical genetic approaches can be used to probe and better define the operational circuitry of the NSC. I describe the development of a small molecule chemical genetic screen of NSCs that uncovered an unappreciated precursor role of a number of neurotransmitter pathways commonly thought to operate primarily in the mature central nervous system (CNS). Given the similarities between stem cells and cancer, I then translated this knowledge to demonstrate that these neurotransmitter regulatory effects are also conserved within cultures of cancer stem cells. I then provide experimental and epidemiologically support for this hypothesis and suggest that neurotransmitter signals may also regulate the expansion of precursor cells that drive tumor growth in the brain. Specifically, I first evaluate the effects of neurochemicals in mouse models of brain tumors. I then outline a retrospective meta-analysis of brain tumor incidence rates in psychiatric patients presumed to be chronically taking neuromodulators similar to those identified in the initial screen.

  • Lamas for COPD Systematic Review
    Comparative safety and effectiveness of inhaled long -acting agents (corticosteroids, beta agonists, anticholinergics) for chronic obstructive pulmonary disease Comprehensive Research Plan: Systematic Review Unit April 4th, 2014 Andrea C. Tricco, PhD1 and Sharon E. Straus, MD, MSc1,2 30 Bond Street, Toronto ON, M5B 1W8 www.odprn.ca [email protected] Background Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation in the lungs [1]. COPD is commonly assessed by clinical examination and spirometry. Important indicators considered in the diagnosis of COPD include age over 40 years and any of the following: 1) progressive and persistent dyspnea that worsens with exercise, 2) chronic cough, 3) chronic sputum production, 4) history of exposure to smoke from tobacco or cooking, occupational dusts and chemicals, and 5) family history of COPD [1]. COPD causes significant burden of illness, reduced quality of life, and premature death [2]. Symptoms include chronic cough, sputum production, and dyspnea [3]. The global prevalence of COPD has been estimated at 7.6% using data from a systematic review including 28 countries [4]. However, this is likely a conservative estimate, due to under-reporting and under-diagnosis. The prevalence and burden of COPD is rising due the greater proportion of elderly people in the population [1]. It is estimated that COPD will be the third-leading cause of death by 2020 [5]. The treatment of COPD usually involves reducing exposure (e.g., smoking cessation, occupation modifications), increasing exercise, and implementing appropriate pharmacologic therapy [1]. The most common drug classes are beta2-agonists, anticholinergics, and methylxanthines. Inhaled corticosteroids (ICS) and systemic corticosteroids are often useful for acute exacerbations.

  • Drugs/Medications Known to Cause Hyperhidrosis Certain Prescriptions
    Drugs/Medications Known to Cause Hyperhidrosis Certain prescriptions and non-prescription medications can cause hyperhidrosis (excess perspiration or sweating) as a side effect. A list of potentially sweat-inducing medications is provided below. Medications are listed alphabetically by generic name. U.S. brand names are given in parentheses, if applicable. This list is provided as a resource and a service. It is not exhaustive and is in no way meant to replace consultation with a medical professional. Although sweating is a known side effect of the medications listed below, in most cases only a small percentage of people using the medicines experience undue sweating (in some cases less than 1%). Medications noted with an “*” and in bold are the most likely to cause sweating and the frequency of sweating as a side effect from these medications may be as high as 50%. Medications noted with an “†” are commonly-prescribed drugs; and those with a “P” are often used for pediatrics.
