Occurrence of deformed wing virus variants in the stingless Melipona subnitida and honey Apis mellifera bee populations in North Eastern Brazil
Deformed wing virus (DWV) is now a global insect pathogen. Brazilian stingless bees are a diverse group often managed in close proximity to honey bees. We investigated the prevalence and load of DWV in 33 stingless bees (Melipona subnitida) and 12 honey bees (Apis mellifera) colonies from NE Brazil. DWV was detected in all colonies with the A and C-variants dominating M. subnitida and A-variant in A. mellifera. Viral loads were 8.83E+07 and 7.19E+07 in M. subnitida and A. mellifera, respectively. On Fernando de Noronha island DWV is low (<1E+03) in honey bees, but we detected high loads (1.6E+08) in nine island M. subnitida colonies, indicating no viral spill-over of DWV has occurred during the past 34 years. Furthermore, the ubiquitous presence of the DWV-C variant in M. subnitida colonies, and rarity in A. mellifera, may suggest limited viral exchange between these two species
INCLUIR É PRECISO
Social inclusion in schools is a process that requires a series of measures, such as adapting pedagogical practices to the educational demands that students present. The aim of this study was to analyze how is the service to students of Recanto das Emas Class 510 School, administrative region of the Federal District, in an inclusive perspective and to know what difficulties teachers face, whether they are prepared, feel qualified or not. , to deal with each type of student with their physical, mental, and so on disabilities. Thus, we made an overview of activities that are developed in EC 510 to confront the theories, laws, norms, guidelines and scholars of the subject in order to know and recognize the theme of Inclusion in reality. You could see that in this school there is a look interested in the human being, there are also trained professionals willing to change scenarios of unhappy children. In general, the school does what it can to ensure that social inclusion is not seen as difficult or impossible. The school's concern with providing quality education and wanting to overcome challenges is noticeable. Another relevant factor was the social context in which the school is inserted; In the community, in its history, references to violence, unemployment, precarious housing were noted and this may cause the low attendance of students in school.A inclusão social nas escolas é um processo que exige uma série de medidas, como por exemplo, adaptar práticas pedagógicas í s demandas educacionais que os alunos apresentam. Pretendeu-se neste estudo analisar como ocorre o atendimento aos estudantes da Escola Classe 510 do Recanto das Emas, região administrativa do Distrito Federal, em uma perspectiva inclusiva e saber quais as dificuldades que os professores enfrentam, se estão preparados, se sentem capacitados ou não, para lidar com cada tipo de aluno com suas deficiências físicas, psíquicas, e etc. Assim, fizemos um apanhado de atividades que são desenvolvidas na EC 510 para confrontar com as teorias, leis, normas, diretrizes e estudiosas do assunto no sentido de conhecer e reconhecer o tema da Inclusão na realidade. Pôde perceber que nessa escola há um olhar interessado pelo ser humano, há também, profissionais capacitados e dispostos a mudar cenários de crianças infelizes. Em linhas gerais, a escola faz o que pode para que a inclusão social não seja vista como algo difícil ou impossível de acontecer .É perceptível a preocupação da escola em oferecer uma educação de qualidade e de querer superar desafios. Outro fator relevante foi o contexto social em que a escola está inserida; notou-se na comunidade, em seu histórico, referências í violência, a desemprego, a moradias precárias e isso pode ocasionar a baixa frequência dos alunos na escola
Physico-chemical and rheological properties of prato cheese during ripening
The influence of storage temperature (6, 12 and 18°C) on texture parameters of Prato cheese were evaluated during 22 days of ripening. A reduction of firmness, gumminess and elasticity was observed; however, cohesiveness and adhesiveness increased. With the increasing temperature, firmness and gumminess reduced, whereas the elasticity, cohesiveness and adhesiveness did not change. It can be concluded that storage temperature influences the texture profile of Prato cheese which present differences in the evaluated parameters during 22 days of ripening.Keywords: Cheese ripening, hard cheese, colour, texture profile analysis

In vitro culture with gemcitabine augments death receptor and NKG2D ligand expression on tumour cells
Much effort has been made to try to understand the relationship between chemotherapeutic treatment of cancer and the immune system. Whereas much of that focus has been on the direct effect of chemotherapy drugs on immune cells and the release of antigens and danger signals by malignant cells killed by chemotherapy, the effect of chemotherapy on cells surviving treatment has often been overlooked. In the present study, tumour cell lines: A549 (lung), HCT116 (colon) and MCF-7 (breast), were treated with various concentrations of the chemotherapeutic drugs cyclophosphamide, gemcitabine (GEM) and oxaliplatin (OXP) for 24 hours in vitro. In line with other reports, GEM and OXP upregulated expression of the death receptor CD95 (fas) on live cells even at sub-cytotoxic concentrations. Further investigation revealed that the increase in CD95 in response to GEM sensitised the cells to fas ligand treatment, was associated with increased phosphorylation of stress activated protein kinase/c-Jun N-terminal kinase and that other death receptors and activatory immune receptors were co-ordinately upregulated with CD95 in certain cell lines. The upregulation of death receptors and NKG2D ligands together on cells after chemotherapy suggest that although the cells have survived preliminary treatment with chemotherapy they may now be more susceptible to immune cell-mediated challenge. This re-enforces the idea that chemotherapy-immunotherapy combinations may be useful clinically and has implications for the make-up and scheduling of such treatments
Balance of IL-10 and Interferon-γ plasma levels in human visceral leishmaniasis: Implications in the pathogenesis
BACKGROUND: Leishmaniasis remains a serious public health problem in several parts of the developing world. Effective prophylactic measurements are hampered by imprecise comprehension of different aspects of the disease, including its immunoregulation. A better comprehension of immunoregulation in human VL may be useful both for designing and evaluating immunoprophylaxis. METHODS: To explore immunoregulatory mechanisms, 20 visceral leishmaniasis (VL) patients were evaluated during active disease and at different periods up to one year after treatment determining their plasma cytokine levels, clinical parameters (palpable spleen and liver) and antibody levels. RESULTS: Elevated plasma levels of IFN-γ and of IL-12 p40 were observed during active disease, significantly decreasing after treatment whereas in vitro Leishmania antigen-stimulated IFN-γ production by PBMC exhibited an inverse pattern being low during disease and increasing steadily thereafter. Absence of IFN-γ activity is a hallmark of VL. The main candidate for blunting IFN-γ activity is IL-10, a cytokine highly elevated in plasma with sharp decrease after treatment. Activity of IL-10 is inferred by high levels of anti-Leishmania specific IgG1 and IgG3. TGF-β had elevated total, but not of active, levels lessening the likelihood of being the IFN-γ counterpart. Spleen or liver size presented a steady decrease but return to normal values at only 120 days after treatment. Anti-Leishmania IgG (total and subclasses) levels and DTH or Leishmania-stimulated lymphocyte proliferation conversion to positive also present a slow decrease after treatment. IL-6 plasma levels were elevated in only a few patients. CONCLUSION: Taken together our results suggest that IFN-γ and IL-10 are the molecules most likely involved in determining fate of disease. After treatment, there is a long delay before the immune profile returns to normal what precludes using plasma cytokine levels as criteria of cure as simpler clinical evaluations, as a palpable spleen or liver, can be used
