    Abstract Background Breed-related health problems in dogs have received increased focus over the last decade. Responsibility for causing and/or solving these problems has been variously directed towards dog breeders and kennel clubs, the veterinary profession, welfare scientists, owners, regulators, insurance companies and the media. In reality, all these stakeholders are likely to share some responsibility and optimal progress on resolving these challenges requires all key stakeholders to work together. The International Partnership for Dogs (IPFD), together with an alternating host organization, holds biennial meetings called the International Dog Health Workshops (IDHW). The Société Centrale Canine (French Kennel Club) hosted the 3rd IDHW, in Paris, in April, 2017. These meetings bring together a wide range of stakeholders in dog health, science and welfare to improve international sharing of information and resources, to provide a forum for ongoing collaboration, and to identify specific needs and actions to improve health, well-being and welfare in dogs. Results The workshop included 140 participants from 23 countries and was structured around six important issues facing those who work to improve dog health. These included individualized breed-specific strategies for health and breeding, extreme conformations, education and communication in relation to antimicrobial resistance, behavior and welfare, genetic testing and population-based evidence. A number of exciting actions were agreed during the meeting. These included setting up working groups to create tools to help breed clubs accelerate the implementation of breed-health strategies, review aspects of extreme conformation and share useful information on behavior. The meeting also heralded the development of an online resource of relevant information describing quality measures for DNA testing. A demand for more and better data and evidence was a recurring message stressed across all themes. Conclusions The meeting confirmed the benefits from inclusion of a diverse range of stakeholders who all play relevant and collaborative parts to improve future canine health. Firm actions were set for progress towards improving breed-related welfare. The next international workshop will be in the UK in 2019 and will be organized by the UK Kennel Club

    Resumo: Neste trabalho são apresentados os resultados preliminares das análises foliares de carbono não estrutural (açúcares, aminoácidos, ácidos orgânicos e amido) e estrutural (lignina e celulose) obtidas num plantio experimental de Eucalyptusgrandisde 3 anos de implantação. As árvores receberam dois níveis de adubação potássica (0 e 17,4 g K m-2 na forma de KCl) e foram submetidas a dois regimes hídricos (100% e 33% da precipitação). Abstract: This work presents the preliminary results about the foliar nonstructural carbon (sugars, aminoacids, organic acids and starch) and structural carbon content (lignin and cellulose) in a three years old Eucalyptus grandisexperimental area. The trees were subjected to two levels of potassium fertilization (0 and 17.4 g K m-2 applied as KCl) as well as two levels of water availability (100% and 33% of rainfall)

    Resumo: Neste trabalho são apresentados os resultados da alocação do carbono (C) recentemente assimilado em árvores de eucalipto submetidas a diferentes tratamentos com relação à disponibilidade hídrica (chuva normal e exclusão de 33%) e fertilização de potássio (0 e 4,5 Kmol ha-1 na forma de KCl), utilizando-se o método da marcação com 13C-CO2 (13C pulse labelling). Observou-se que o aumento da velocidade de crescimento das árvores aumenta a partição do C fixado na madeira e a implicação prática desta constatação, considerando-se a produção de uma quantidade fixa de madeira, é que o consumo de recursos será menor maximizando-se a produtividade numa pequena área, ao contrário de plantações pouco produtivas ocupando áreas maiores. Abstract: This work presents the results about the carbon allocation ( 13 C pulse labelling) in a three years old Eucalyptus grandis experimental area, where the trees were subjected to two levels of potassium fertilization (0 and 4.5 Kmol ha -1 applied as KCl) as well as two levels of water availability (normal rainfall and exclusion of 33% of rainfall). The observed increase in the growth velocity of the trees enhanced the C partition in the wood. Therefore the resources consumption for the production of a fixed amount of wood will be lower in a smaller and more productive area than in a less productive larger plantation

    Resumo: A aquicultura tem apresentado um crescimento nos últimos anos consolidando-se como um setor de grande importância econômica. Diante deste crescimento, surge à necessidade de desenvolvimento de processos de monitoramento ambiental que assegurem uma correta interpretação dos possíveis impactos e a melhor forma de diminuí-los. O presente trabalho teve por objetivo avaliar a concentração de metais potencialmente tóxicos e de carbono e nitrogênio, em sedimentos coletados na área de influência direta de piscicultura em tanques rede no reservatório de Furnas. A área de coleta é composta por 4 braços do rio Grande todos no município de Guapé (MG). Em 3 dos 4 braços existem piscicultura em tanques rede e um foi utilizado como controle. Foram realizadas 3 coletas de sedimento em maio, agosto e outubro de 2013, utilizando-se draga de Ekman-Birge. No laboratório, as amostras foram secas, moídas e digeridas para a determinação elementar de Cu (cobre), Pb (chumbo) e Zn (zinco) por Espectrometria de Absorção Atômica com Chama (F-AAS). Os resultados encontrados nas três coletadas variaram de 11,6 a 36,9 mg.L-1 para o Cu, de 95,2 a 184,8 mg.L-1 para o Pb e de 12,7 a 86,3 mg.L-1 para o Zn. O carbono (C) e o nitrogênio (N) total foram determinados por combustão a seco, com resultados que variam de 0,71 a 2,34 % para o C e de 0,097 a 0,224 % para o N. Abstract: Aquaculture has growing in the last decades establishing as sector of great economic importance. The growing of the sector, inputs a necessity to develop environmental monitoring processes to ensuring a correct interpretation of the possible impacts and how the best way to reduce them. This study aimed to evaluate the concentration of potentially toxic metals and carbon and nitrogen in sediments, collected in the area of direct influence of fish farming in tanks, located in Furnas reservoir. The sampling area consists of 4 arms of the rio Grande in the city of Guape (MG). In arms 2 to 4 there are fish farming in net tanks and arm 1 was used as control. Three samples were taken in all sampling sites, during May, August and October 2013, using Ekman-Birge dredge. At the laboratory, samples were dried, ground and digested for elemental determination of Cu (copper), Pb (lead) and Zn (zinc) Spectrometry Flame Atomic Absorption (F-AAS). The results in the three collected ranged from 11.6 to 36.9 mg.L -1 of Cu, 95.2 to 184.8 mg.L -1 for Pb and 12.7 to 86.3 mg.L -1 for Zn. The carbon (C) and nitrogen (N) were determined by the total dry combustion with results ranging from 0.71 to 2.34% for C and 0.097 to 0.224% for

    Hybrid Quantum and Classical Mechanical Monte Carlo Simulations of the Interaction of Hydrogen Chloride with Solid Water Clusters

    Monte Carlo simulations using a hybrid quantum and classical mechanical potential were performed for crystal and amorphous-like HCl-water(n) clusters The subsystem composed by HCl and one water molecule was treated within Density Functional Theory, and a classical force field was used for the rest of the system. Simulations performed at 200 K suggest that the energetic feasibility of HCl dissociation strongly depends on its initial placement within the cluster. An important degree of ionization occurs only if HCl is incorporated into the surface. We observe that local melting does not play a crucial role in the ionization process.Comment: 14 Latex pages with 4 postscript figures, to appear in Chem. Phys. Let

    International Veterinary Epilepsy Task Force Consensus Proposal: Diagnostic approach to epilepsy in dogs

    Get PDF
    This article outlines the consensus proposal on diagnosis of epilepsy in dogs by the International Veterinary Epilepsy Task Force. The aim of this consensus proposal is to improve consistency in the diagnosis of epilepsy in the clinical and research settings. The diagnostic approach to the patient presenting with a history of suspected epileptic seizures incorporates two fundamental steps: to establish if the events the animal is demonstrating truly represent epileptic seizures and if so, to identify their underlying cause. Differentiation of epileptic seizures from other non-epileptic episodic paroxysmal events can be challenging. Criteria that can be used to make this differentiation are presented in detail and discussed. Criteria for the diagnosis of idiopathic epilepsy (IE) are described in a three-tier system. Tier I confidence level for the diagnosis of IE is based on a history of two or more unprovoked epileptic seizures occurring at least 24 h apart, age at epileptic seizure onset of between six months and six years, unremarkable inter-ictal physical and neurological examination, and no significant abnormalities on minimum data base blood tests and urinalysis. Tier II confidence level for the diagnosis of IE is based on the factors listed in tier I and unremarkable fasting and post-prandial bile acids, magnetic resonance imaging (MRI) of the brain (based on an epilepsy-specific brain MRI protocol) and cerebrospinal fluid (CSF) analysis. Tier III confidence level for the diagnosis of IE is based on the factors listed in tier I and II and identification of electroencephalographic abnormalities characteristic for seizure disorders. The authors recommend performing MRI of the brain and routine CSF analysis, after exclusion of reactive seizures, in dogs with age at epileptic seizure onset 6 years, inter-ictal neurological abnormalities consistent with intracranial neurolocalisation, status epilepticus or cluster seizure at epileptic seizure onset, or a previous presumptive diagnosis of IE and drug-resistance with a single antiepileptic drug titrated to the highest tolerable dose

    Evaluation of the influence of kyphosis and scoliosis on intervertebral disc extrusion in French bulldogs

    Get PDF
    Although thoracic vertebral malformations with kyphosis and scoliosis are often considered incidental findings on diagnostic imaging studies of screw-tailed brachycephalic breeds, they have been suggested to interfere with spinal biomechanics and intervertebral disc degeneration. It is however unknown if an abnormal spinal curvature also predisposes dogs to develop clinically relevant intervertebral disc herniations. The aim of this study was to evaluate if the occurrence of thoracic vertebral malformations, kyphosis or scoliosis would be associated with a higher prevalence of cervical or thoracolumbar intervertebral disc extrusion in French bulldogs
