The Following Studies Received Ethical Approval by Institutional And/Or National Review Committees If Appropriate
The following studies received ethical approval by institutional and/or national review committees if appropriate. Manchester AVA Spring Meeting April 2017 Cardiovascular findings during pre-anesthetic assessment in dogs undergoing two different pre-anesthetic assessment protocols and usefulness of the diagnostic tests performed S Diez-Bernal1, G Ortiz-Diez2, SP Monteagudo-Franco3, P Ruhi-Velasco4, C Garcia- Echarri4, A Perez-Higueras4, V Salazar-Nussio5. 1Anesthesia Service, University of Bern, Bern, Switzerland; 2Cardiology Service, Alfonso X El Sabio University, Madrid, Spain; 3Diagnostic Imaging Service, Alfonso X El Sabio University, Madrid, Spain; 4Alfonso X El Sabio University, Madrid, Spain; 5Anesthesia Service, Alfonso X El Sabio University, Madrid, Spain. The objectives of this study were to describe cardiovascular abnormalities (CVA) found during pre-anesthetic assessment in dogs in a veterinary teaching hospital and to evaluate the usefulness of the different diagnostic tests performed. One hundred and eight client-owned dogs underwent a basic pre-anesthetic assessment protocol including history, physical examination, hematology and biochemistry performed and evaluated by an anesthesia specialist; and a comprehensive pre-anesthetic assessment protocol that included, in addition to the tests performed in the basic assessment protocol, thoracic radiographs, ECG, and echocardiography evaluated by a licensed veterinarian. CVA were identified in twenty-five of ninety-seven dogs (25.8%) by cardiac auscultation; in 15 dogs (13.9%) by ECG; in 6 dogs (5.6%) by thoracic radiographs; and in 39 dogs (36.1%) by echocardiography (95% of which were diagnosed of chronic valvular heart disease, CVHD). Since CVHD was the cardiovascular condition that showed the highest prevalence, sensitivity, specificity and likelihood ratios of the other performed clinical tests were calculated for the diagnosis of this condition (taking echocardiography as gold standard). -
History Lectured on Midwifery at St Bartholomew’S Hospital and and Was in Attendance at the Births of All of Her Children
J R Coll Physicians Edinb 2012; 42:274–9 Paper http://dx.doi.org/10.4997/JRCPE.2012.317 © 2012 Royal College of Physicians of Edinburgh Sir Charles Locock and potassium bromide MJ Eadie Honorary Research Consultant and Emeritus Professor, Faculty of Health Sciences, University of Queensland, Royal Brisbane and Women’s Hospital, Australia ABSTRACT On 12 May 1857, Edward Sieveking read a paper on epilepsy to the Correspondence to M Eadie Royal Medical and Chirurgical Society in London. During the discussion that Faculty of Health Sciences, followed Sir Charles Locock, obstetrician to Queen Victoria, was reported to have University of Queensland, Royal Brisbane and Women’s commented that during the past 14 months he had used potassium bromide to Hospital, Herston, successfully stop epileptic seizures in all but one of 14 or 15 women with ‘hysterical’ Brisbane 4029, Australia or catamenial epilepsy. This report of Locock’s comment has generally given him credit for introducing the first reasonably effective antiepileptic drug into medical Tel 61 2 (0)7 38311704 e-mail [email protected] practice. However examination of the original reports raises questions as to how soundly based the accounts of Locock’s comments were. Subsequently, others using the drug to treat epilepsy failed to obtain the degree of benefit that the reports of Locock’s comments would have led them to expect. The drug might not have come into more widespread use as a result, had not Samuel Wilks provided good, independent evidence for the drug’s antiepileptic efficacy in 1861. KEYWORDS Epilepsy treatment, Charles Locock, potassium bromide, Edward Sieveking, Samuel Wilks DECLaratIONS OF INTERESTS No conflicts of interest declared. -

Canine Status Epilepticus Care
Vet Times The website for the veterinary profession https://www.vettimes.co.uk CANINE STATUS EPILEPTICUS CARE Author : Stefano Cortellini, Luisa de Risio Categories : Vets Date : August 2, 2010 Stefano Cortellini and Luisa de Risio discuss emergency management techniques for a condition that can claim the lives of 25 per cent of afflicted dogs – as the quicker the start of treatment, the better the chances of control STATUS epilepticus (SE) is a neurological emergency with a mortality of up to 25 per cent in dogs (Bateman, 1999). SE can be defined as continuous epileptic seizure (ES) activity lasting longer than five minutes, or as two or more ES with incomplete recovery of consciousness interictally. SE has also been defined as continuous seizure activity lasting for 30 minutes or longer. However, emergency treatment to stop the ES should be administered well before the defined 30-minute time. The most common type of SE is generalised tonic-clonic status. When this is prolonged, the tonic- clonic clinical manifestations can become subtle, with only small muscle twitching and altered mentation. This status is called electromechanical dissociation, as continued abnormal electrical activity in the brain persists while the motor manifestations are minimal to absent. In these cases, emergency anti-epileptic treatment is necessary as for tonic-clonic status. SE can be divided into two stages. The first stage is characterised by generalised tonicclonic seizures and an increase in autonomic activity that causes tachycardia, hypertension, 1 / 7 hyperglycaemia, hyperthermia and increased cerebral blood flow. The second stage of SE starts after about 30 minutes and is characterised by hypotension, hypoglycaemia, hyperthermia, hypoxia, decreased cerebral blood flow, cerebral oedema and increased intracranial pressure. -
Studies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (II) Composition of Salt in Anode Compartment
Journal of NUCLEARSCIENCE and TECHNOLOGY,7 (10), p. 522~526 (October 1970). Studies on Isotope Separation of Lithium by Electromigration in Fused Lithium Bromide and Potassium Bromide Mixture, (II) Composition of Salt in Anode Compartment Yoshinobu YAMAMURA* and Shin SUZUKI* Received May 13, 1970 Accurate knowledge on the salt composition in the anode compartment is indispensable when 6Li is to be highly enriched by electromigration in fused LiBr-KBr mixture. A study was made on the dependence on temperature shown by the salt composition in the anode com- partment. It was observed that sustained electromigration led to a salt composition in the anode compartment that was determined by the prevailing temperature. The composition was observed for various temperatures between 380- and 740-C: In terms of the ratio Li/K in chemical equivalent, the values were 1.31 at 380-C, 1.29 at 420-C, 1.31 at 460-C, 1.41 at 500-C, 1.76 at 540-C, 1.82 at 580-C, 1.95 at 620-C, 2.16 at 680-C and 2.34 at 740-C. These results can be explained by assuming that the fused LiBr-KBr mixture is a system composed of two simple salts and their eutectic, and that at temperatures below 550-C, which is the melting point of LiBr, LiBr and KBr are dissolved in fused eutectic, while KBr is dissolved in the fused eutectic and LiBr at temperatures between 550- and 738-C, which latter is the melting point of KBr.

Global Lithium Sources—Industrial Use and Future in the Electric Vehicle Industry: a Review
resources Review Global Lithium Sources—Industrial Use and Future in the Electric Vehicle Industry: A Review Laurence Kavanagh * , Jerome Keohane, Guiomar Garcia Cabellos, Andrew Lloyd and John Cleary EnviroCORE, Department of Science and Health, Institute of Technology Carlow, Kilkenny, Road, Co., R93-V960 Carlow, Ireland; [email protected] (J.K.); [email protected] (G.G.C.); [email protected] (A.L.); [email protected] (J.C.) * Correspondence: [email protected] Received: 28 July 2018; Accepted: 11 September 2018; Published: 17 September 2018 Abstract: Lithium is a key component in green energy storage technologies and is rapidly becoming a metal of crucial importance to the European Union. The different industrial uses of lithium are discussed in this review along with a compilation of the locations of the main geological sources of lithium. An emphasis is placed on lithium’s use in lithium ion batteries and their use in the electric vehicle industry. The electric vehicle market is driving new demand for lithium resources. The expected scale-up in this sector will put pressure on current lithium supplies. The European Union has a burgeoning demand for lithium and is the second largest consumer of lithium resources. Currently, only 1–2% of worldwide lithium is produced in the European Union (Portugal). There are several lithium mineralisations scattered across Europe, the majority of which are currently undergoing mining feasibility studies. The increasing cost of lithium is driving a new global mining boom and should see many of Europe’s mineralisation’s becoming economic. The information given in this paper is a source of contextual information that can be used to support the European Union’s drive towards a low carbon economy and to develop the field of research. -

The density and refractive index values of [bmim][I] appeared to be the highest among three ionic liquids (ILs). However, the experimental viscosity values of [bmim][Br] were higher than those of [bmim][BF4], while the heat capacities and heats of dilution of [bmim][BF4] were higher than those of [bmim][Br]. The cyclic voltammogram of [bmim][br] and [bmim][BF4] indicated electrochemical windows in the stability range from 2.7 V of [bmim][[Br] to 4.7 V of [bmim][BF4].
