  • PK of Medcm Against Nerve Agents, Which Have Been Integrated with PK and PD Data for the Nerve Agents Sarin and VX
    UNIVERSITY OF SOUTHAMPTON FACULTY OF MEDICINE Institute of Developmental Sciences The Pharmacokinetics of Medical Countermeasures Against Nerve Agents by Stuart Jon Armstrong Thesis for the degree of Doctor of Philosophy November 2014 UNIVERSITY OF SOUTHAMPTON ABSTRACT FACULTY OF MEDICINE Institute of Developmental Sciences Thesis for the degree of Doctor of Philosophy THE PHARMACOKINETICS OF MEDICAL COUNTERMEASURES AGAINST NERVE AGENTS Stuart Jon Armstrong Nerve agents are organophosphorus compounds that irreversibly inhibit acetylcholinesterase, causing accumulation of the neurotransmitter acetylcholine and this excess leads to an overstimulation of acetylcholine receptors. Inhalation exposure to nerve agent can be lethal in minutes and conversely, skin exposure may be lethal over longer durations. Medical Countermeasures (MedCM) are fielded in response to the threat posed by nerve agents. MedCM with improved efficacy are being developed but the efficacy of these cannot be tested in humans, so their effectiveness is proven in animals. It is UK Government policy that all MedCM are licensed for human use. The aim of this study was to test the hypothesis that the efficacy of MedCM against nerve agent exposure by different routes could be better understood and rationalised through knowledge of the MedCM pharmacokinetics (PK). The PK of MedCM was determined in naïve and nerve agent poisoned guinea pigs. PK interactions between individual MedCM drugs when administered in combination were also investigated. In silico simulations to predict the concentration-time profiles of different administration regimens of the MedCM were completed using the PK parameters determined in vivo. These simulations were used to design subsequent in vivo PK studies and to explain or predict the efficacy or lack thereof for the MedCM.

Received: 29 November 2019; Accepted: 25 March 2020; Published: 27 March 2020 Abstract: Despite the important role that the growth hormone (GH)/IGF-I axis plays in vascular homeostasis, these kind of growth factors barely appear in articles addressing the neovascularization process. Currently, the vascular endothelium is considered as an authentic gland of internal secretion due to the wide variety of released factors and functions with local effects, including the paracrine/autocrine production of GH or IGF-I, for which the endothelium has specific receptors. In this comprehensive review, the evidence involving these proangiogenic hormones in arteriogenesis dealing with the arterial occlusion and making of them a potential therapy is described. All the elements that trigger the local and systemic production of GH/IGF-I, as well as their possible roles both in physiological and pathological conditions are analyzed.

  • Chemical Warfare: Nerve Agents Steven J
    Chemical Warfare: Nerve Agents Steven J. Hatfill, M.D. Nerve agents, sometimes also called nerve gases, are a class of chemical weapons that disrupt the transmission of nerve signals in the brain and from the brain to the muscles and organs. The repeated documented use of these agents on civilians implies that a threshold has now been crossed and it is likely that this threat will continue into the foreseeable future. Hence, a review of the medical effects and treatment of nerve-agent exposure is warranted, most particularly for the highly classified Russian Novichok nerve agents. Historical Background Figure 1. The Lethal Amount of VX (Small White Drop) on a The first nerve agents were accidentally discovered 1-Cent Coin Photo modified from the U.S. Soldier Biological / Chemical in Germany in 1936 as a byproduct of research into new Command, Domestic Preparedness Program, Hospital Provider insecticides. The first actual agent was an organophosphate Section compound named tabun. A year later, a team of German scientists created an organophosphate that was 10 times more lethal that they called sarin (named after the team of scientists: Schrader, Ambros, Ritter, and von der Linde). During The Novichok Nerve Agents World War II, another new organophosphate called soman (derived from the Greek “to sleep” ) was developed.1 Although Russia made significant advances in new nerve-agent nerve agents were manufactured and stockpiled, these were development throughout the Cold War. They manufactured soman, sarin, and their own version of VX (called VR) in never used on the battlefield. After the war the G-series a binary form.

Fluorescence-based detection, where the sensing material undergoes a chemical reaction with the agent causing a measurable change in the luminescence, is one method for sensing and identifying nerve agents. Most studies use the simulants diethylchlorophosphate (DCP) and di- iso-propylfluorophosphate (DFP) to evaluate the performance of sensors due to their reduced toxicity relative to the OP nerve agents. While detection of nerve agent simulants in solution is relatively widely reported there are fewer reports on vapor detection using solid-state This is the author manuscript accepted for publication and has undergone full peer review but has not been through the copyediting, typesetting, pagination and proofreading process, which may lead to differences between this version and the Version of Record.

M. Liu ([email protected]) Published by Copernicus Publications on behalf of the European Geosciences Union. 391 Abstract Nutrient concentrations among the Chinese rivers and bays vary 10–75 fold depending on nutrient elements. The silicic acid levels in South China rivers are higher than those from North China rivers and the yields of dissolved silicate increased from the north to 5 the south of China, indicating the effect of climate on weathering. The nutrient levels in Chinese rivers are higher than those from the large and less-disturbed world rivers such as Amazon and Zaire, but comparable to the values for European and North American polluted and eutrophic rivers like the Loire and Po. This may be ascribed to both of extensive leaching and influences from agricultural and domestic activities over the 3− 10 drainage basins of Chinese rivers.

But experimenters search most diligently, and with the greatest effort, in exactly those places where it seems most likely that we can prove our theories wrong. In other words, we are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress. Richard P.
