    A pitiose é uma doença granulomatosa que atinge eqüinos, caninos, bovinos, felinos e humanos e ocorre em áreas tropicais, subtropicais ou temperadas (Meireles et al., 1993; Mendoza et al., 1996), causada pelo omiceto Pythium insidiosum (De Cock et al., 1987). A espécie eqüina é a mais atingida, principalmente nas formas cutânea e subcutânea, seguida dos caninos (Mendoza et al., 1996). A enfermidade em eqüinos caracteriza-se pela formação de granulomas eosinofílicos, com a presença de massas necróticas chamadas de kunkers (Mendoza e Alfaro, 1986; Meireles et al., 1993). Em humanos, a doença é mais comum no sudeste asiático, caracterizando-se por formas sistêmicas com arterites e também formas oftálmicas e subcutâneas, sendo as duas últimas associadas a a e b-talassemias (Imwidthaya, 1994; Imwidthaya, 1995). Vários tratamentos têm sido utilizados, principalmente em eqüinos, incluindo tratamento químico (antifúngicos), cirúrgico e imunoterápico. A imunoterapia, proposta inicialmente por Miller (1981), surgiu como uma alternativa concreta para o controle da doença e tem apresentado resultados promissores (Monteiro, 1999).

    Pythiosis in horses is a proliferative and ulcerative disease that primarily affects the skin and subcutaneous tissue of limbs, thoracic-abdominal region and head. This disease sometimes can also affect limb bones or cause tumoral masses in abdomen. Usually, the cutaneous cases are confused with habronemiasis. The disease is more common in marshy areas, places with formation of slow drainage ponds and aquatic vegetation under high temperatures. The aim of this study was to describe the development of facial lesions in a horse caused by pythiosis in Cuiaba, Mato Grosso, and, additionally to discuss relevant issues regarding the diagnosis, clinical course and response to immunotherapy treatment.Publicação 955.

    A pitiose e causada pelo fungo Pythium insidiosum e acomete eqüinos, felinos, caninos, bovinos e humanos. A especie equina é a mais atingida e a lesao causada pelo fungo se restringe, geralmente, a pele e tecidos subcutaneos. Casos de pitiose com envolvimento de outros tecidos, como ossos, linfonodos, olhos, arterias e orgaos dos sistemas digestivo e respiratorio, ja foram descritos nas diferentes especies susceptiveis. Para viabilizar o uso da imunoterapia no tratamento da pitiose equina, nas condicoes dessa regiao, produziu-se e testou-se a eficiencia de um imunoterapico liofilizado (Pythium-Vac®) que permitisse armazenamento por periodo longo e em temperatura ambiente. Para o preparo do imunoterapico usaram-se isolados de P. insidiosum, obtidos de lesoes de equinos com pitiose no Pantanal e no Rio Grande do Sul. Entre março e junho de 1996, 19 animais de varias fazendas da sub-regiao da Nhecolandia, Mato Grosso do Sul, com lesoes recentes e antigas de pitiose foram reunidos na fazenda Nhumirim, da Embrapa Pantanal. Os equinos foram tratados com injecoes subcutaneas na regiao do pescoco a cada 14 dias. Sessenta e tres por cento dos animais estavam recuperados apos 5,3 aplicacoes do imunoterapico. Diferentemente do esperado, 83% dos animais com lesoes antigas e 60% com lesoes recentes foram curados. Esses resultados sao opostos aos encontrados em outros estudos sobre a eficiência do tratamento imunoterapico.bitstream/item/105021/1/COT67.pdfCNPGC

    Não existe droga antifúngica eficiente contra o agente causador da pitiose equina. Esta doença que, como regra, incapacita ou ocasiona o óbito dos animais acometidos já foi verificada em todas as regiões brasileiras. Visando analisar o impacto econômico determinado pelo emprego do imunoterápico Pitium-Vac no controle da pitiose equina no país de 2003 a 2009, foram utilizados dados reais da adoção deste insumo agropecuário e do custo do tratemento e uma estimativa indexada do valor dos animais tratados ou não

    New light for time series: international collaboration in ship-based ecosystem monitoring.

    Ship-based biogeochemical and ecological time series are one of the most valuable tools to characterize and quantify ocean ecosystems. These programs continuously provided major breakthroughs in understanding ecosystem variability, allow quantification of the ocean carbon cycle, and help understand the processes that link biodiversity, food webs, and changes in services that benefit human societies. A quantum jump in regional and global ocean ecosystem science can be gained by aggregating observations from individual time series that are distributed across different oceans and which are managed by different countries. The collective value of these data is greater than that provided by each time series individually. However, maintaining time series requires a commitment by the science community and sponsor agencies.. Based on the success of existing initiatives, e.g. ICES and SCOR working groups, IOC-UNESCO launched the International Group for Marine Ecological Time Series (IGMETS, http://igmets.net) to promote collaborations across different individual projects, and jointly look at holistic changes within different ocean regions. The effort explores the reasons and connections for changes in phytoplankton and zooplankton at a global level and identifies locations where particularly large changes may be ocurring. This compilation will facilitate better coordination, communication, and data intercomparability among time series.IEO (RADIALES) IOC-UNESC

    Measurement of the cross-section and charge asymmetry of WW bosons produced in proton-proton collisions at s=8\sqrt{s}=8 TeV with the ATLAS detector

    Get PDF
    This paper presents measurements of the W+μ+νW^+ \rightarrow \mu^+\nu and WμνW^- \rightarrow \mu^-\nu cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS experiment at the LHC and correspond to a total integrated luminosity of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the 1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured with an uncertainty between 0.002 and 0.003. The results are compared with predictions based on next-to-next-to-leading-order calculations with various parton distribution functions and have the sensitivity to discriminate between them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables, submitted to EPJC.

    Search for chargino-neutralino production with mass splittings near the electroweak scale in three-lepton final states in √s=13 TeV pp collisions with the ATLAS detector

    A search for supersymmetry through the pair production of electroweakinos with mass splittings near the electroweak scale and decaying via on-shell W and Z bosons is presented for a three-lepton final state. The analyzed proton-proton collision data taken at a center-of-mass energy of √s=13  TeV were collected between 2015 and 2018 by the ATLAS experiment at the Large Hadron Collider, corresponding to an integrated luminosity of 139  fb−1. A search, emulating the recursive jigsaw reconstruction technique with easily reproducible laboratory-frame variables, is performed. The two excesses observed in the 2015–2016 data recursive jigsaw analysis in the low-mass three-lepton phase space are reproduced. Results with the full data set are in agreement with the Standard Model expectations. They are interpreted to set exclusion limits at the 95% confidence level on simplified models of chargino-neutralino pair production for masses up to 345 GeV

    Search for direct stau production in events with two hadronic tau-leptons in root s=13 TeV pp collisions with the ATLAS detector

    A search for the direct production of the supersymmetric partners ofτ-leptons (staus) in final stateswith two hadronically decayingτ-leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of139fb−1, recorded with the ATLAS detector at the LargeHadron Collider at a center-of-mass energy of 13 TeV. No significant deviation from the expected StandardModel background is observed. Limits are derived in scenarios of direct production of stau pairs with eachstau decaying into the stable lightest neutralino and oneτ-lepton in simplified models where the two staumass eigenstates are degenerate. Stau masses from 120 GeV to 390 GeV are excluded at 95% confidencelevel for a massless lightest neutralino
