    A ocorrĂȘncia de doenças neurolĂłgicas Ă© elevada na clĂ­nica mĂ©dica dos animais, porĂ©m poucos estudos documentam a composição normal do lĂ­quor de ovinos, em especial o da raça Santa InĂȘs. O objetivo deste estudo foi o de estabelecer parĂąmetros de normalidade para as caracterĂ­sticas fĂ­sico-quĂ­micas e citolĂłgicas do lĂ­quor de ovinos desta raça. Para isso, foram utilizados 40 ovinos, com idades entre seis a dezoito meses, para a realização da punção lombossacral de lĂ­quor. Foi observado um padrĂŁo lĂ­mpido e incolor, e a mĂ©dia para densidade foi de 1,006 ± 0,0064, a concentração de proteĂ­nas foi de 25,27 ± 6,64 mg/dL e a de glicose de 46,89 ± 10,99 mg/dL. Quanto Ă s atividades enzimĂĄticas, foram observadas mĂ©dias de 80,79 ± 116,72 U/L para creatina quinase (CK); 17,43 ± 11,91 U/L para lactato desidrogenase (LDH) e 17,08 ± 3,85 U/L para aspartato aminotransferase (AST). Os achados obtidos para contagem global de leucĂłcitos foram de 4,61 ± 4,96 cĂ©lulas/”L (0 a 15 linfĂłcitos, 0 a 10 monĂłcitos, 1 a 14 neutrĂłfilos). Diante da carĂȘncia de dados de referĂȘncia para parĂąmetros do lĂ­quor de ovinos Santa InĂȘs, sugere-se que os resultados obtidos nesta pesquisa sejam considerados valores normais na clĂ­nica de ovinos e, assim, contribuam no diagnĂłstico de doenças neurolĂłgicas nesta raça.

    Solar Irradiance Forecasting Using Dynamic Ensemble Selection

    Get PDF
    Solar irradiance forecasting has been an essential topic in renewable energy generation. Forecasting is an important task because it can improve the planning and operation of photovoltaic systems, resulting in economic advantages. Traditionally, single models are employed in this task. However, issues regarding the selection of an inappropriate model, misspecification, or the presence of random fluctuations in the solar irradiance series can result in this approach underperforming. This paper proposes a heterogeneous ensemble dynamic selection model, named HetDS, to forecast solar irradiance. For each unseen test pattern, HetDS chooses the most suitable forecasting model based on a pool of seven well-known literature methods: ARIMA, support vector regression (SVR), multilayer perceptron neural network (MLP), extreme learning machine (ELM), deep belief network (DBN), random forest (RF), and gradient boosting (GB). The experimental evaluation was performed with four data sets of hourly solar irradiance measurements in Brazil. The proposed model attained an overall accuracy that is superior to the single models in terms of five well-known error metrics

    Guidelines for the management of neuroendocrine tumours by the Brazilian gastrointestinal tumour group

    Get PDF
    Neuroendocrine tumours are a heterogeneous group of diseases with a significant variety of diagnostic tests and treatment modalities. Guidelines were developed by North American and European groups to recommend their best management. However, local particularities and relativisms found worldwide led us to create Brazilian guidelines. Our consensus considered the best feasible strategies in an environment involving more limited resources. We believe that our recommendations may be extended to other countries with similar economic standards.Univ Sao Paulo, Inst Canc Estado Sao Paulo, BR-01246000 Sao Paulo, BrazilUniv Sao Paulo, Fac Med, Dept Radiol & Oncol, BR-01246903 Sao Paulo, BrazilHosp Sirio Libanes, BR-01308050 Sao Paulo, BrazilHosp Moinhos de Vento Porto Alegre, BR-90035000 Porto Alegre, RS, BrazilOncoctr, BR-30360680 Belo Horizonte, MG, BrazilUniv Fed Rio Grande do Sul, Dept Cirurgia, BR-90040060 Porto Alegre, RS, BrazilHosp Clin Porto Alegre, BR-90035903 Porto Alegre, RS, BrazilUniv Fed Ceara, Fac Med, Dept Fisiol & Farmacol, BR-60020180 Fortaleza, Ceara, BrazilHosp Univ Walter Cantidio, BR-60430370 Fortaleza, Ceara, BrazilInst Nacl Canc, BR-20230240 Rio De Janeiro, BrazilUniv Sao Paulo, Fac Med, Disciplina Endocrinol & Metabol, BR-01246903 Sao Paulo, BrazilAC Camargo Canc Ctr, Dept Surg, BR-01509010 Sao Paulo, BrazilUniv Sao Paulo, Fac Med, Dept Gastroenterol, Sao Paulo, BrazilUniv Fed Ciencias Saude Porto Alegre, BR-90050170 Porto Alegre, RS, BrazilHosp Albert Einstein, BR-05652900 Sao Paulo, BrazilHosp Base, Fac Med Sao Jose do Rio Preto, BR-15090000 Sao Paulo, BrazilSanta Casa Sao Jose do Rio Preto, BR-15025500 Sao Jose Do Rio Preto, BrazilPontificia Univ Catolica Parana, Hosp Erasto Gaertner, BR-81520060 Curitiba, Parana, BrazilUniv Fed Rio Grande do Norte, BR-59300000 Natal, RN, BrazilUniv Sao Paulo, Inst Coracao, BR-05403900 Sao Paulo, BrazilAC Camargo Canc Ctr, Med Oncol, BR-01509010 Sao Paulo, BrazilUniv Fed Sao Paulo, Disciplina Gastroenterol, BR-04021001 Sao Paulo, BrazilHosp Sao Rafael, BR-41253190 Salvador, BA, BrazilHosp Canc Barretos, Dept Cirurgia Aparelho Digest Alto & Hepatobiliop, BR-14784400 Sao Paulo, BrazilUniv Sao Paulo, Fac Med, Dept Patol, BR-01246903 Sao Paulo, BrazilClin AMO, BR-1950640 Salvador, BA, BrazilHosp Sao Jose, BR-01323001 Sao Paulo, BrazilUniv Nove de Julho, BR-02111030 Sao Paulo, BrazilUniv Fed Sao Paulo, Disciplina Gastroenterol, BR-04021001 Sao Paulo, BrazilWeb of Scienc

    EM TEMPOS GLOBAIS, UM “NOVO” LOCAL: a Ford na Bahia

    Get PDF
    O artigo analisa a dinĂąmica da RegiĂŁo Metropolitana de Salvador (RMS) a partir da implantação da Ford, discutindo a perspectiva do ‘lugar’ (a periferia metropolitana), dentro de uma relação assimĂ©trica com os negĂłcios globais na era da flexibilidade. O texto caracteriza o complexo Ford de Camaçari a partir da reestruturação produtiva e das mudanças na organização e funcionamento dos territĂłrios e, na segunda parte, seus impactos sobre a periferia metropolitana de Salvador. Na conclusĂŁo demonstra que as mesmas circunstĂąncias que permitiram a vinda da montadora para Camaçari constrangem as ambiçÔes originais de melhor equacionamento entre crescimento econĂŽmico e progresso social: a flexibilidade dos novos arranjos, que tornam os espaços perifĂ©ricos estratĂ©gicos, compromete o “enraizamento” do investimento; a “produção enxuta”, exĂ­gua de emprego e diligente na sua precarização, inibe os benefĂ­cios sociais. PALAVRAS CHAVE: reestruturação produtiva, mercado de trabalho, indĂșstria automobilĂ­stica, periferia metropolitana, segregação socioespacial. IN GLOBAL TIMES, A “NEW” PLACE: Ford in Bahia Ângela Franco This paper makes an analysis of the dynamics of the Metropolitan Area of Salvador (in Portuguese, RMS) starting from the implantation of Ford, discussing the perspective of the ‘local’ (the metropolitan periphery), inside of an asymmetrical relationship with global businesses in the age of flexibility. The Ford Automotive Compound is caracterized in the first part of the paper from its productive reestructuring and changes in the organization and work of territories, and, in the second part, from its impact on the the metropolitan periphery from Salvador. In its conclusion it demonstrates that the same circumstances that allowed the arrival of the automotive maker in Camaçari constrain the original ambitions of better ratio between economical growth and social progress: the flexibility of the new automotive production methods, making peripheric spaces strategic, compromises on the permanence of the investments; and the “streamlined production”, easy on job production and hard on job flexibilization inhibit social benefits. KEYWORDS: productive restructuring, job market, automobile industry, metropolitan periphery, socioespatial segregation. EN PERIODE DE MONDIALISATION, UN “NOUVEAU” LOCAL: Ford Ă  Bahia Ângela Franco Cet article traite de l’analyse de la dynamique de la RĂ©gion MĂ©tropolitaine de Salvador (RMS), Ă  partir de l’implantation de l’usine Ford. On y discute de la perspective du “lieu” (la pĂ©riphĂ©rie mĂ©tropolitaine), dans une relation asymĂ©trique avec les affaires globales Ă  une Ă©poque de flexibilitĂ©. On y caractĂ©rise le complexe Ford de Camaçari Ă  partir de la restructuration productive et des changements dans l’organisation et le fonctionnement des territoires. Ses impacts sur la pĂ©riphĂ©rie mĂ©tropolitaine de Salvador sont prĂ©sentĂ©s dans la deuxiĂšme partie. En conclusion, on y dĂ©montre que ce sont les mĂȘmes circonstances qui ont permis l’arrivĂ©e de l’usine de montage Ă  Camaçari qui reprĂ©sentent une contrainte pour les ambitions qui, Ă  l’origine, voulaient atteindre une meilleure Ă©quation entre la croissance Ă©conomique et le progrĂšs social. La flexibilitĂ© de ces nouveaux arrangements, qui rendent les espaces pĂ©riphĂ©riques stratĂ©giques, compromet “l’enracinement” des investissements, la “production exiguĂ«â€, l’exiguĂŻtĂ© des emplois et la diligence dans leur prĂ©carisation, elle inhibe les avantages sociaux. MOTS-CLÉS: restructuration productive, marchĂ© du travail, industrie automobile, pĂ©riphĂ©rie mĂ©tropolitaine, sĂ©grĂ©gation sociale et spatiale.

    Rehabilitation and release of confiscated songbirds into the wild: A pilot study

    Get PDF
    Songbirds are currently the most prevalent animals in illegal trafficking in Brazil and other countries, so they are often confiscated, and this poses legal, ethical, and conservation challenges. Returning them to nature requires complex and expensive management, a topic that is sparingly addressed in the literature. Here, we described the processes and costs associated with an attempt to rehabilitate and release confiscated songbirds into the wild. A total of 1,721 songbirds of several species were quarantined, rehabilitated, and released, primarily on two farms located within their typical geographical distribution. Health assessments were performed on samples from 370 birds. Serology revealed no antibodies against Newcastle disease, and Salmonella spp. cultures were negative. Real-time polymerase chain reactions detected M. gallisepticum in samples from seven birds. Atoxoplasma spp. and Acuaria spp. infections, sepsis, and trauma were the top causes of bird death. About 6% of the released birds were recaptured, within an average period of 249 days after release, and at a mean distance of 2,397 meters from the release sites. The majority of these birds were found with free-living mates within or close to fragments of transitional ecoregions with native or cultivated grasslands, and native groves/forests, and shrublands. However, eucalyptus plantations with rich understory regeneration provided a suitable environment for the released forest species to settle, since they were recaptured during the defense of these sites. Over half of the recaptured birds presented behavioral profiles with both dominant and tame traits. Birds with dominant traits are more likely to settle in habitats and face the live decoys during fieldwork, whereas birds with tame characteristics tend to accept close contact with humans. Ultramarine grosbeak (Cyanoloxia brissonii), the least common species among those released, at the release sites showed an almost 2-fold recapture rate in the shortest mean distances from the release sites. This suggests less territory competition, perhaps a major factor of bird re-establishment here. The total per-bird cost was USD 57. Our findings suggested suitable survival and re-establishment of confiscated songbirds in the wild, when managed as we describe

    Spinning Gland Transcriptomics from Two Main Clades of Spiders (Order: Araneae) - Insights on Their Molecular, Anatomical and Behavioral Evolution

    Get PDF
    Characterized by distinctive evolutionary adaptations, spiders provide a comprehensive system for evolutionary and developmental studies of anatomical organs, including silk and venom production. Here we performed cDNA sequencing using massively parallel sequencers (454 GS-FLX Titanium) to generate ∌80,000 reads from the spinning gland of Actinopus spp. (infraorder: Mygalomorphae) and Gasteracantha cancriformis (infraorder: Araneomorphae, Orbiculariae clade). Actinopus spp. retains primitive characteristics on web usage and presents a single undifferentiated spinning gland while the orbiculariae spiders have seven differentiated spinning glands and complex patterns of web usage. MIRA, Celera Assembler and CAP3 software were used to cluster NGS reads for each spider. CAP3 unigenes passed through a pipeline for automatic annotation, classification by biological function, and comparative transcriptomics. Genes related to spider silks were manually curated and analyzed. Although a single spidroin gene family was found in Actinopus spp., a vast repertoire of specialized spider silk proteins was encountered in orbiculariae. Astacin-like metalloproteases (meprin subfamily) were shown to be some of the most sampled unigenes and duplicated gene families in G. cancriformis since its evolutionary split from mygalomorphs. Our results confirm that the evolution of the molecular repertoire of silk proteins was accompanied by the (i) anatomical differentiation of spinning glands and (ii) behavioral complexification in the web usage. Finally, a phylogenetic tree was constructed to cluster most of the known spidroins in gene clades. This is the first large-scale, multi-organism transcriptome for spider spinning glands and a first step into a broad understanding of spider web systems biology and evolution
