Crescimento vegetativo do maracujazeiro-do-mato (Passiflora cincinnata mast.) sob diferentes niveis de reposição de água.

Sabe-se que a água é fator limitante para qualquer cultura, e ainda mais se esta cultura estiver localizada na região semi-árida nordestina, tornando-se fator de risco para a produção. Deste modo, objetivou-se avaliar o efeito de diferentes níveis de reposição de água sobre o comportamento vegetativo do maracujazeiro-do-mato, visando subsídios para a agricultura irrigada no semi-árido do Estado da Paraíba

Desenvolvimento tecnológico e caracterização nutricional de massa alimentícia enriquecido com farinha de peixe.

As massas se destacam pela riqueza em carboidratos e carência em quantidade e qualidade proteica. No entanto, ocupa um lugar de destaque entre os alimentos mais consumidos pela população. Diante deste contexto, este trabalho tem como objetivo produzir massas alimentícias com diferentes concentrações de peixe (Tambaqui, Colossoma macropomum) e linhaça. Cinco formulações de massas foram preparadas: uma amostra controle e três amostras com diferentes concentrações de peixe (10%, 15% e 20%) e mais uma amostra com a associação entre as farinhas de peixe e linhaça (10% + 10%). As amostras foram avaliadas quanto ao teor de umidade, lipídios, proteínas, fibras, cinzas, carboidratos e valor calórico total. O delineamento inteiramente casualizado foi adotado com três repetições, determinando a média e o desvio padrão dos valores obtidos para cada amostra. As formulações com maior teor de peixe apresentaram maior teor de umidade, proteína e cinzas. A adição de linhaça na massa ocasionou um aumento no valor calórico e nos valores de fibras. A fortificação de massas com diferentes concentrações de farinha de peixe aumentou o valor nutricional do produto, além de compor uma alternativa importante para melhora do perfil nutricional deste alimento.VII SIMCOPE

Levantamento de reconhecimento de baixa e média intensidade dos solos do Estado de Pernambuco.

Os estudos de solos foram desenvolvidos em nível de reconhecimento de baixa e média intensidade, escala 1:100.000, cobrindo toda superfície do Estado de Pernambuco, com aproximadamente 98.938 km2. Os trabalhos foram realizados por meio da parceria entre o Centro Nacional de Pesquisa de Solos (CNPS) - Escritório Regional de Pesquisa e Desenvolvimento Nordeste (ERP/NE) e o Governo do Estado de Pernambuco. O objetivo principal do levantamento de solos foi gerar dados para dar suporte à elaboração do Zoneamento Agroecológico do Estado. A metodologia utilizada seguiu as normas do Serviço Nacional de Levantamento e Conservação de Solos (SNLCS), atual Centro Nacional de Pesquisa de Solos. Os resultados dos estudos mostram que os solos de maior expressão, ocupando cerca de 61% da área, pertencem às classes dos Podzólicos (25%), Solos Litólicos (20%) e, Planossolos e Solonetz Solodizados (16%). Ocupam cerca 23% da área, os solos das classes dos Latossolos (9%), Brunos Não Cálcicos (9%) e Areias Quartzosas (5%). Perfazem cerca de 7% da área, os solos das classes dos Regossolos (5%) e Solos Aluviais (2%). Cerca de 4% da área é ocupada por solos diversos, incluindo os Cambissolos, Gleissolos, Podzóis, Vertissolos, Solos Indiscriminados de Mangues, Brunizéns, Terra Roxa Estruturada e Plintossolos. Os tipos de terrenos, principalmente afloramentos de rocha, ocupam uma superfície ao redor de 3% da área. Cerca de 2% da superfície do Estado correspondem às águas internas.bitstream/item/69954/1/Boletim-de-Pesquisa-Final-11.pdf; bitstream/item/216858/1/Mapa-de-reconhecimento-de-baixa-e-media-intensidade-de-solos-do-estado-de-Pernambuco.pd

Use of transgenic Aedes aegypti in Brazil: risk perception and assessment.

The OX513A strain of Aedes aegypti, which was developed by the British company Oxitec, expresses a self-limiting transgene that prevents larvae from developing to adulthood. In April 2014, the Brazilian National Technical Commission on Biosafety completed a risk assessment of OX513A and concluded that the strain did not present new biological risks to humans or the environment and could be released in Brazil. At that point, Brazil became the first country to approve the unconstrained release of a genetically modified mosquito. During the assessment, the commission produced a comprehensive list of ? and systematically analysed ? the perceived hazards. Such hazards included the potential survival to adulthood of immature stages carrying the transgene ? should the transgene fail to be expressed or be turned off by exposure to sufficient environmental tetracycline. Other perceived hazards included the potential allergenicity and/or toxicity of the proteins expressed by the gene, the potential for gene flow or increased transmission of human pathogens and the occupation of vacant breeding sites by other vector species. The Zika epidemic both elevated the perceived importance of Ae. aegypti as a vector ? among policy-makers and regulators as well as the general public ? and increased concerns over the release of males of the OX513A strain. We have therefore reassessed the potential hazards. We found that release of the transgenic mosquitoes would still be both safe and of great potential value in the control of diseases spread by Ae. aegypti, such as the chikungunya, dengue and Zika virus disease

GAMMA-ORYZANOL HAS AN EQUIVALENT EFFICACY AS A LIPID-LOWERING AGENT COMPARED TO FIBRATE AND STATIN IN TWO DYSLIPIDEMIA MICE MODELS

Objective: A substantial fraction of the population is intolerant or does not respond well to the recommended treatments for dyslipidemia. The purpose of this study was to evaluate the efficacy ofgamma-oryzanol (γ-ORZ) treatment in acute and long-term mouse experimental models of dyslipidemia in comparison toGemfibrozil and Simvastatin. Methods: For the acute dyslipidemia-induced model, dyslipidemia was induced in 40 mice using a single intra-peritoneal administration of Triton WR-1339. For the long-termmodel, dyslipidemia was induced in 24 mice using a hypercholesterolemic diet over 14 days. Thereafter, animals were divided into different groups of treatment,and orally received treatments with gamma-oryzanol (5, 25, 50mg. kg-1), gemfibrozil or simvastatin. For biochemical analysis, glucose, total cholesterol and triacylglycerols were measured. Body weight and net food intake was registered weekly, and urea, creatinine, AST and ALT levels were evaluated. The data were analyzed by analysis of variance (ANOVA), followed by the Student-Newman-Keuls method,and p value of less than 0.05 was considered significant. Results: Only the highest dose of γ-ORZ exhibited significant protective effects. Gamma-oryzanol andGemfibrozil treatments reduced total cholesterol and triacylglycerols levels in a similar manner in the acute model. In the second model, γ-ORZ and simvastatin treatments reduced glucose and total cholesterol levels in the same way. In addition, the administration ofγ-ORZ did not cause any adverse events, or significantly altered hepatic enzymes levels, plasmatic urea or creatinine concentrations. Conclusion: The results of this study suggest that gamma-oryzanol acts as a potential lipid-lowering agent, reducing triglycerides and total cholesterol in dyslipidemia-induced models

Transiting exoplanets from the CoRoT space mission IX. CoRoT-6b: a transiting `hot Jupiter' planet in an 8.9d orbit around a low-metallicity star

The CoRoT satellite exoplanetary team announces its sixth transiting planet in this paper. We describe and discuss the satellite observations as well as the complementary ground-based observations - photometric and spectroscopic - carried out to assess the planetary nature of the object and determine its specific physical parameters. The discovery reported here is a `hot Jupiter' planet in an 8.9d orbit, 18 stellar radii, or 0.08 AU, away from its primary star, which is a solar-type star (F9V) with an estimated age of 3.0 Gyr. The planet mass is close to 3 times that of Jupiter. The star has a metallicity of 0.2 dex lower than the Sun, and a relatively high $^7$Li abundance. While thelightcurveindicatesamuchhigherlevelof activity than, e.g., the Sun, there is no sign of activity spectroscopically in e.g., the [Ca ] H&K lines
