    The caprine arthritis encephalitis is an important viral and most important infectious disease in dairy goats. The infection causes several economic losses. The high prevalence CAEV infection in countries that export goat genetics generated a great concern, since the international trade might introduce the virus in different countries by embryo transfer spreading the disease. Thus, the aim of the study was to evaluate the risk of caprine arthritis encephalitis virus (CAEV) transmission by in vivo embryos from naturally infected donors. Thus, results of the present study showed no transmission of CAEV by embryos originated from CAEV positive donors by embryos from transcervical method washing treatment.

    Resumo: Este estudo objetivou avaliar o comportamento sexual e a dinĂąmica ovulatĂłria de cabras da raça Toggenburg apĂłs a indução do estro com dispositivo intravaginal de progesterona durante seis, nove e 12 dias de permanĂȘncia. No momento da inserção do dispositivo e 24 horas antes da retirada do dispositivo, foi administrado 5mg de dinoprost e 200UI de eCG, respectivamente. A dinĂąmica ovulatĂłria foi acompanhada por ultrassonografia a cada oito horas, enquanto o estro foi observado a cada 12 horas. Todas as cabras apresentaram estro. O intervalo da retirada do dispositivo ao inĂ­cio do estro foi de 29,5 ± 9,6 para G6dias; 34,0 ± 6,0 e 32,4 ± 7,7h, G9dias e G12dias, respectivamente. Igualmente, foi encontrada diferença (P0,05). Todos os protocolos foram eficientes em induzir o estro sincronizado em cabras da raça Toggenburg, trabalhando em conjunto com a eficiĂȘncia reprodutiva e produtiva desses animais. [Reproductive parameters after induction of estrus with different ranges of the vaginal device in acyclic Toggenburg goats]. Abstract: This study aimed to evaluate the sexual behavior and the ovulatory dynamics of Toggenburg goats after induction of synchronized estrus by an intravaginal progesterone device for six, nine and twelve days. At the device insertion and 24 h before the device removal, 5mg of dinoprost and 200 UI of eCG was administered, respectively. The ovulatory dynamics was assessed by ultrasound every 8 h, while the sexual behavior was observed every 12 h. All goats showed estrus. The intervals from device removal to estrus were 29.5 ± 9.7, 34.0 ± 6.0 and 32.4 ± 7.7h to G6days, G9days and G12days, respectively. Iqually, it was found difference (P0.05). All treatments were effective for the induction of synchronized estrus in Toggenburg goats, working jointly with the reproductive and productive efficiency of these animals

    The chronic otitis media with cholesteatoma (COMC) may evoluate to intracranial and extra cranial complications, including the labyrithine fĂ­stulae. In this study, we present the evolution of our patients with labyrinthine fĂ­stulae. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: Ten out 82 patients with COMC had labyrinthine fĂ­stulae and underwent surgery from January/2001 to April/2002. They were assessed by clinical exam, computed tomography scans, and pre and postoperative audiogram. RESULTS: Hearing loss, otorrhea, tinnitus and dizziness were present in 100%, 90%,80%, and 40% of the cases. In one patient the fĂ­stulae was seen only in the coronal CT-scan, in another patient the fĂ­stulae was not seen neither in coronal nor axial images. Among the patients who had tinnitus, 66% referred improvement of this complaint after surgery. DISCUSSION: in the cases without invasion of the perilymphatic space, we noticed a tendency of improvement of the postoperative audiogram pattern and clinical outcome. In the extensive fĂ­stulae, on the other hand, there were no clinical changes. CONCLUSION: The CT-scan remains the best exam to assess the COMC with 90% of sensitivity for labyrinthine fĂ­stulae. In the stage II we had a good postoperative outcome.A otite mĂ©dia crĂŽnica colesteatomatosa (OMCC) pode cursar com complicaçÔes intra e/ou extracranianas, entre elas a fĂ­stula labirĂ­ntica. Neste trabalho, mostramos a incidĂȘncia e a evolução dos casos de fĂ­stula labirĂ­ntica decorrentes da OMCC em nosso serviço. FORMA DE ESTUDO: ClĂ­nico prospectivo. MATERIAL E MÉTODO: Dez pacientes com fĂ­stula labirĂ­ntica, do total de 82 pacientes com OMCC, foram submetidos Ă  cirurgia no perĂ­odo de janeiro de 2001 a abril de 2002 e avaliados atravĂ©s de exame otorrinolaringolĂłgico completo, tomografia computadorizada e audiometria prĂ© e pĂłs-operatĂłria. RESULTADOS: Perda auditiva, otorrĂ©ia, zumbido e vertigem estavam presentes em 100%, 90%, 80% e 40% dos casos respectivamente na avaliação clĂ­nica prĂ©-operatĂłria. Em um paciente a fĂ­stula aparecia apenas nos cortes tomogrĂĄficos coronais e tivemos um caso de falso-negativo. Dos pacientes com zumbido, 66% apresentaram melhora deste quadro no pĂłs-operatĂłrio. DISCUSSÃO: Nos casos de fĂ­stula sem invasĂŁo do espaço perilinfĂĄtico (atĂ© grau II), notamos uma tendĂȘncia de melhora dos quadros clĂ­nico e audiomĂ©trico apĂłs a cirurgia. Nas fĂ­stulas extensas, por outro lado, o resultado audiomĂ©trico se manteve inalterado. CONCLUSÃO: A tomografia continua sendo o exame de escolha para os quadros de OMCC com sensibilidade de 90% para fĂ­stulas labirĂ­nticas. Nas fĂ­stulas grau II a cirurgia apresenta bom resultado funcional.Universidade Federal de SĂŁo Paulo (UNIFESP) Escola Paulista de Medicina Departamento de Otorrinolaringologia e DistĂșrbios da Comunicação HumanaUNIFESP, EPM, Depto. de Otorrinolaringologia e DistĂșrbios da Comunicação HumanaSciEL

    Cold coffee seeds storage with different water content.

    Coffee seeds are classified as intermediate because they have low tolerance to desiccation and low longevity. Consequently, moisture control and storage conditions are important factors in maintaining the physiological quality of these seeds. Thus, the objective in this work was to evaluate the water content effect on coffee seed longevity. Seeds of five Coffea arabica cultivars from the 2016/2017 crop were used. Part of the harvested seeds was dried in the shade until reach 12% moisture and the other part did not go through drying process, remaining with 40% water content. The seeds were stored in a cold chamber at 10 oC for a period of nine months, and the physiological quality was evaluated every three months by germination, root protrusion, seedlings with expanded cotyledonary leaves, seedling dry mass and enzymatic analysis of catalase enzymes and superoxide dismutase. Regardless of the cultivar, wet seeds coffee storage provides better maintenance of physiological quality for up to nine months. Seedling vigor is reduced throughout the storage period, regardless of seed water content

    Trypanosoma cruzi Adjuvants Potentiate T Cell-Mediated Immunity Induced by a NY-ESO-1 Based Antitumor Vaccine

    Immunological adjuvants that induce T cell-mediate immunity (TCMI) with the least side effects are needed for the development of human vaccines. Glycoinositolphospholipids (GIPL) and CpGs oligodeoxynucleotides (CpG ODNs) derived from the protozoa parasite Trypanosoma cruzi induce potent pro-inflammatory reaction through activation of Toll-Like Receptor (TLR)4 and TLR9, respectively. Here, using mouse models, we tested the T. cruzi derived TLR agonists as immunological adjuvants in an antitumor vaccine. For comparison, we used well-established TLR agonists, such as the bacterial derived monophosphoryl lipid A (MPL), lipopeptide (Pam3Cys), and CpG ODN. All tested TLR agonists were comparable to induce antibody responses, whereas significant differences were noticed in their ability to elicit CD4+ T and CD8+ T cell responses. In particular, both GIPLs (GTH, and GY) and CpG ODNs (B344, B297 and B128) derived from T. cruzi elicited interferon-gamma (IFN-Îł) production by CD4+ T cells. On the other hand, the parasite derived CpG ODNs, but not GIPLs, elicited a potent IFN-Îł response by CD8+ T lymphocytes. The side effects were also evaluated by local pain (hypernociception). The intensity of hypernociception induced by vaccination was alleviated by administration of an analgesic drug without affecting protective immunity. Finally, the level of protective immunity against the NY-ESO-1 expressing melanoma was associated with the magnitude of both CD4+ T and CD8+ T cell responses elicited by a specific immunological adjuvant

    A inserção do Brasil no mercado mundial de alumĂ­nio: incorporando contribuiçÔes da Ecologia PolĂ­tica para a SaĂșde Coletiva

    Get PDF
    O presente artigo discute a inserção do Brasil no mercado mundial de alumĂ­nio a partir dos referenciais teĂłricos da ecologia polĂ­tica, da economia polĂ­tica do territĂłrio e da saĂșde coletiva. A conjuntura contemporĂąnea da economia mundial tem sido pautada pela desregulamentação e liberalização, caracterĂ­sticos do ideĂĄrio neoliberal propalado pelas naçÔes centrais. A maior participação do Brasil nesse mercado tem sido realizada a partir do aumento da produção e exportação de commodities agrĂĄrias e metĂĄlicas, como o alumĂ­nio. Nesse sentido, a partir dos paradigmas da ecologia polĂ­tica, o texto propĂ”e uma anĂĄlise das consequĂȘncias socioambientais, assim como sobre novas territorialidades que se produzem e reproduzem dentro de uma lĂłgica econĂŽmica que privilegia as naçÔes centrais. Do mesmo modo, procura-se compreender os dilemas da saĂșde coletiva sob uma perspectiva holĂ­stica e integradora na qual se articula aos modelos de desenvolvimento econĂŽmico. Percebe-se que a produção e exportação de alumĂ­nio primĂĄrio, apesar de apresentar um valor agregado maior, esconde um conjunto difuso de impactos que afetam o ambiente e a saĂșde coletiva
