Evaluation of the productive and vegetative aspects of the cultivar 'Imperial Gala' apple tree with EM-9 interstem in different lengths.

The obtaining of a compact plant, with less vigor and high productivity, equivalent to a conventional plant, constitutes a strong tendency in the current horticulture, aiming at a raising of the fruit production at the same planted area. One of the techniques that have had success nowadays is the interstem use. This study was developed in a commercial orchard of Randon Agro Silvo Pastoril S.A. (RASIP), located in the Rio Grande do Sul state, Brazil. The purpose of this work was to evaluate the vegetative and productive development of apple trees of 'Imperial Gala' with different lengths of EM-9 interstem. The treatments consisted of five interstem lengths: 10, 15, 20, 25, 30 cm. In the seventh year of implantation the following parameters were evaluated: the height of the plant, the diameter of the 'Imperial Gala' 5 cm above the second graft point, the volume of the tree-head (height, width and length), the number of bud per branch, and the number of fruits per lineal centimeter of branch. Through this study it could be concluded that the greater interstem (30 cm) presented better indices with relation of vigor control. However, the number of fruits per lineal centimeter of branch with the interstem of 10 cm offered only significant superiority, when compared with the interstem of 30 cm. Using interstem technique allows to gather the benefits of the rootstock 'Marubakaido' and to control excessive vigour with the interstem EM-9.Trabalho apresentado no VIII International Symposium on Temperate Zone Fruits in the Tropics and Subtropics, Florianópolis, 2007

COMPILATION OF ACTIVE FAULT DATA IN PORTUGAL FOR USE IN SEISMIC HAZARD ANALYSIS

To estimate where future earthquakes are likely to occur, it is essential to combine information about past earthquakes with knowledge about the location and seismogenic properties of active faults. For this reason, robust probabilistic seismic hazard analysis (PSHA) integrates seismicity and active fault data. Existing seismic hazard assessments for Portugal rely exclusively on seismicity data and do not incorporate data on active faults. Project SHARE (Seismic Hazard Harmonization in Europe) is an EC-funded initiative (FP7) that aims to evaluate European seismic hazards using an integrated, standardized approach. In the context of SHARE, we are developing a fully-parameterized active fault database for Portugal that incorporates existing compilations, updated according to the most recent publications. The seismogenic source model derived for SHARE will be the first model for Portugal to include fault data and follow an internationally standardized approach. This model can be used to improve both seismic hazard and risk analyses and will be combined with the Spanish database for use in Iberian- and European-scale assessments

RAD6 promotes DNA repair and stem cell signaling in ovarian cancer and is a promising therapeutic target to prevent and treat acquired chemoresistance

Ovarian cancer (OC) is the most deadly gynecological cancer and unlike most other neoplasms, survival rates for OC have not significantly improved in recent decades. We show that RAD6, an ubiquitin-conjugating enzyme, is significantly overexpressed in ovarian tumors and its expression increases in response to carboplatin chemotherapy. RAD6 expression correlated strongly with acquired chemoresistance and malignant behavior of OC cells, expression of stem cell genes and poor prognosis of OC patients, suggesting an important role for RAD6 in ovarian tumor progression. Upregulated RAD6 enhances DNA damage tolerance and repair efficiency of OC cells and promotes their survival. Increased RAD6 levels cause histone 2B ubiquitination-mediated epigenetic changes that stimulate transcription of stem cell genes, including ALDH1A1 and SOX2, leading to a cancer stem cell phenotype, which is implicated in disease recurrence and metastasis. Downregulation of RAD6 or its inhibition using a small molecule inhibitor attenuated DNA repair signaling and expression of cancer stem cells markers and sensitized chemoresistant OC cells to carboplatin. Together, these results suggest that RAD6 could be a therapeutic target to prevent and treat acquired chemoresistance and disease recurrence in OC and enhance the efficacy of standard chemotherapy

Aplicação de extrato aquoso de sorgo para elaboração de cobertura comestível de folhas de ora-pro-nóbis minimamente processado.

Ora-pro-nóbis é uma hortaliça não convencional que apresenta elevados teores de proteínas, sendo pouco explorada no Brasil. Coberturas comestíveis podem ser aplicadas em alimentos para prolongar a vida de prateleira ou incorporar algum nutriente. Este trabalho objetivou avaliar o efeito da aplicação de uma cobertura comestível em folhas de ora-pro-nóbis minimamente processado, por análises microbiológicas, físico-químicas, compostos bioativos e atividade antioxidante, verificando a segurança, estabilidade e um possível caráter funcional do produto. Em nenhuma amostra houve diferença significativa na interação da cobertura comestível com o tempo de estocagem refrigerada (8 dias, 7 oC). As amostras apresentaram-se seguras para consumo durante todo o período avaliado (ausência de Salmonella sp., < 3 NMP/g de Coliformes a 45 oC e máximo 2,4 UFC/g de Contagem Total de Bolores e Leveduras). Os resultados médios gerais ao longo de todo o período de armazenamento refrigerado avaliado para cada variável foram: pH = 4,62; ATT = 0,82 g de ac. cítrico/100 g de amostra; cor instrumental: L = 42,78; a* = -13,95; b* = 21,53; umidade = 87,08%; perda de massa = 5,30%; carotenoides = 913,27 µg de carotenoides/g de amostra seca; compostos fenólicos = 11,44 mg GAE/100 g de amostra seca e atividade antioxidante = 359,65 µmol TE/g amostra em base seca. Concluiu-se que o protocolo definido foi eficiente no processamento mínimo de orapro-nóbis, foi possível desenvolver uma cobertura comestível adicionada de extrato aquoso de sorgo e esta não alterou significativamente a vida de prateleira do produto, porém trouxe ganhos expressivos de compostos fenólicos
