The role of knowledge networks in facilitating the creation of climate information services
nowledge networks are collections of individuals and teams who work together across organizational, spatial and disciplinary boundaries to invent and share a body of knowledge. Climate services are tools and application that support decision-making by transforming raw climate data into tailored information. They call for co-development practices in place and for successful collaboration between different stakeholders. Knowledge networks for climate services are intermediaries that facilitate the interaction between upstream (providers) and downstream (user) actors operating at various scales (local, national, regional and supranational). They assist the decision-making process of a wide set of users by creating windows of opportunity and by delivering usable climate information. The aim of this work is to frame and assess the efficiency of knowledge networks for climate services in promoting innovation and facilitate its diffusion. First, we characterize knowledge networks learning from insights of a multidisciplinary literature. Second, we analyse the purpose, the process and the audience of each knowledge network for climate services by screening their programmatic documents. We then assess the efficiency of knowledge networks by performing content analysis of interviews with knowledge network managers and by checking for the existence of inconsistencies or gaps with the initial objectives. We find knowledge networks for climate services pursue four objectives: coordination, innovation promotion, science-policy interface and support to members. We also find inadequate tools to monitor the members activities, but a strong positioning within the climate services domain. On the communication side, knowledge networks for climate services mostly interact with developers of climate services but they face challenges in sharing the members’ activities with users. Our work fills a significant knowledge gap and helps providing new tools of performance assessment in absence of a clearly defined methodology. The identification of bottlenecks and under-performing mechanisms in the climate information services sphere allows the elaboration of strategies to improve the status quo and facilitates the diffusion of these innovations
Exosome and Microvesicle-Enriched Fractions Isolated from Mesenchymal Stem Cells by Gradient Separation Showed Different Molecular Signatures and Functions on Renal Tubular Epithelial Cells
Several studies have suggested that extracellular vesicles (EVs) released from mesenchymal stem cells (MSCs) may mediate MSC paracrine action on kidney regeneration. This activity has been, at least in part, ascribed to the transfer of proteins/transcription factors and different RNA species. Information on the RNA/protein content of different MSC EV subpopulations and the correlation with their biological activity is currently incomplete. The aim of this study was to evaluate the molecular composition and the functional properties on renal target cells of MSC EV sub-populations separated by gradient floatation. The results demonstrated heterogeneity in quantity and composition of MSC EVs. Two peaks of diameter were observed (90–110 and 170–190 nm). The distribution of exosomal markers and miRNAs evaluated in the twelve gradient fractions showed an enrichment in fractions with a flotation density of 1.08–1.14 g/mL. Based on this observation, we evaluated the biological activity on renal cell proliferation and apoptosis resistance of low (CF1), medium (CF2) and high (CF3) floatation density fractions. EVs derived from all fractions, were internalized by renal cells, CF1 and CF2 but not CF3 fraction stimulated significant cell proliferation. CF2 also inhibited apoptosis on renal tubular cells submitted to ischemia-reperfusion injury. Comparative miRNomic and proteomic profiles reveal a cluster of miRNAs and proteins common to all three fractions and an enrichment of selected molecules related to renal regeneration in CF2 fraction. In conclusion, the CF2 fraction enriched in exosomal markers was the most active on renal tubular cell proliferation and protection from apoptosis.

Editorial : extreme events in the developing world
This Research Topic “Extreme Events in the Developing World” showcases a selection of articles that develop our knowledge of extreme events in the developing world. Papers range from those presenting recent evidence for and future likelihood of changes in the occurrence and exposure to extreme events, together with examples of the impacts of extreme events in a variety of sectors. Papers also consider the range of climate services responses to this challenge, highlighting the need for new types of weather and climate information, new methods of producing and communicating that information in order to reduce risk, as well as providing some key examples of success stories, with a particular focus on Africa. Our intention here is to balance some of the bad news with what might work, and how we might learn from such examples.UK Natural Environment Research Council (NERC);

De lá para cá, a revista contabiliza mais de 250 artigos publicados de todos os cantos do Brasil, com contribuições internacionais constantes de África, Portugal e Espanha. No período de 2015-2017, se ampliou o conselho para cinquenta e seis pesquisadores, de universidades europeias (de países como Alemanha, Áustria, Inglaterra, Portugal, Espanha, França, Itália e Reino Unido), de universidades nas Américas (de países como Canadá, Costa Rica, Colômbia, Chile, Equador, Estados Unidos, Guatemala, México e Venezuela), além de pesquisadores de universidades africanas (de países como África do Sul, Moçambique e Cabo Verde)
Epilepsy Detection Using Artificial Neural Networks
Epilepsy is a neurological disorder, where there is a cluster of brain cells that behave in a hyperexcitable manner, the individual can promote injuries, trauma or, in more severe cases, sudden death. Electroencephalogram (EEG) is the most used way to detect epileptic seizures. Therefore, more simplified methods of analysis of the EEG can help in the diagnosis and treatment of these individuals more quickly. In this study, we extracted pertinent EEG characteristics to assess the epileptic seizure period. We use Perceptron Multilayer artificial neural networks to classify the period of the crisis, obtaining a more efficient diagnosis. The multilayer neural network obtained an accuracy of 98%. Thus, the strategy of extracting characteristics and the architecture of the assigned network were sufficient for a rapid and accurate diagnosis of epilepsy

Impact of EGFR genetic variants on glioma risk and patient outcome
B.M. Costa and M. Viana-Pereira contributed equally to this work; The authors thank the Immunochemotherapy Department of Hospital S. Marcos, and Clinica Laboratorial Dr. Edgar Botelho Moniz, S. Tirso, Portugal, for their helpful assistance in the management of controlsBACKGROUND: The epidermal growth factor receptor (EGFR) regulates important cellular processes and is frequently implicated in human tumors. Three EGFR polymorphisms have been described as having a transcriptional regulatory function: two single-nucleotide polymorphisms in the essential promoter region, -216G/T and -191C/A, and a polymorphic (CA)(n) microsatellite sequence in intron 1. We aimed to elucidate the roles of these EGFR polymorphisms in glioma susceptibility and prognosis.
METHODS: We conducted a case-control study with 196 patients with glioma and 168 cancer-free controls. Unconditional multivariate logistic regression models were used to calculate ORs and 95% confidence intervals. A Cox regression model was used to evaluate associations with patient survival. False-positive report probabilities were also assessed.
RESULTS: None of the EGFR -216G/T variants was significantly associated with glioma risk. The -191C/A genotype was associated with higher risk for glioma when the (CA)(n) alleles were classified as short for ≤16 or ≤17 repeats. Independently of the (CA)(n) repeat cutoff point used, shorter (CA)(n) repeat variants were significantly associated with increased risk for glioma, particularly glioblastoma and oligodendroglioma. In all tested models with different (CA)(n) cutoff points, only -191C/A genotype was consistently associated with improved survival of patients with glioblastoma.
CONCLUSIONS: Our findings implicate EGFR -191C/A and the (CA)(n) repeat polymorphisms as risk factors for gliomas, and suggest -191C/A as a prognostic marker in glioblastoma. Impact: Our data support a role of these EGFR polymorphisms in determining glioma susceptibility, with potential relevance for molecularly based stratification of patients with glioblastoma for individualized therapies.Schering-Plough Farma, PortugalFundação para a Ciência e a Tecnologia (FCT) - SFRH/BPD/33612/2009; SFRH/BD/29145/200
PROT-OVT: Plano Regional de Ordenamento do Territorio do Oeste e Vale do Tejo
Os princípios, objectivos e orientações consagrados no Programa Nacional da Política de Ordenamento
do Território (PNPOT), aprovado pela Lei n.º 58/2007, de 4 de Setembro, são desenvolvidos nos vários
planos regionais de ordenamento do território (PROT) que, por sua vez, constituem um quadro de
referência estratégico para os planos directores municipais (PDM). No processo de elaboração e
revisão articulada destes três pilares fundamentais do sistema de gestão territorial, em que assenta
a política de ordenamento do território e do urbanismo, cabe aos PROT uma posição de charneira
fundamental.
O significado e as potencialidades dos PROT são ainda significativamente ampliados pela articulação
com a revisão dos PDM. Face a uma nova geração de PDM, que se pretendem mais estratégicos, os
PROT fornecem um quadro de referência estratégica de longo prazo que permite aos municípios
estabelecerem as suas opções de desenvolvimento e definirem regras de gestão territorial compatíveis
com o modelo consagrado para a região.
Os PROT, além de um pilar da política de desenvolvimento territorial, são documentos fundamentais
para a definição dos programas de acção das intervenções co-financiadas pelos Fundos Estruturais e
de Coesão da União Europeia.
Os PROT são instrumentos de desenvolvimento territorial e de natureza estratégica. Em matéria
de conteúdo, estabelecem a estrutura regional do sistema urbano, das redes de infra‑estruturas e
dos equipamentos de interesse regional e definem os objectivos e princípios quanto à localização
das actividades e os grandes investimentos públicos; as suas normas fixam o quadro estratégico, as
orientações de carácter genérico e as directrizes para o ordenamento do território regional.
O PROT do Oeste e Vale do Tejo (PROT OVT) visa, neste contexto, a espacialização de estratégias de
desenvolvimento territorial nos territórios das NUTS III do Oeste, Médio Tejo e Lezíria do Tejo. Por isso,
ocupa, entre o nível nacional e o nível municipal, uma posição chave para a definição das estratégias
e das opções de desenvolvimento e de ordenamento regional. O PROT OVT é pois um instrumento
privilegiado para promover a reflexão estratégica do desenvolvimento do Oeste e do Vale do Tejo e
acolher a tomada de decisão quanto às opções de desenvolvimento territorial [...]info:eu-repo/semantics/publishedVersio
