This project is the second in the series of EC-financed parts of the Graphene Flagship. The Graphene Flagship is a 10 year research and innovation endeavour with a total project cost of 1,000,000,000 euros, funded jointly by the European Commission and member states and associated countries. The first part of the Flagship was a 30-month Collaborative Project, Coordination and Support Action (CP-CSA) under the 7th framework program (2013-2016), while this and the following parts are implemented as Core Projects under the Horizon 2020 framework. The mission of the Graphene Flagship is to take graphene and related layered materials from a state of raw potential to a point where they can revolutionise multiple industries. This will bring a new dimension to future technology a faster, thinner, stronger, flexible, and broadband revolution. Our program will put Europe firmly at the heart of the process, with a manifold return on the EU investment, both in terms of technological innovation and economic growth. To realise this vision, we have brought together a larger European consortium with about 150 partners in 23 countries. The partners represent academia, research institutes and industries, which work closely together in 15 technical work packages and five supporting work packages covering the entire value chain from materials to components and systems. As time progresses, the centre of gravity of the Flagship moves towards applications, which is reflected in the increasing importance of the higher - system - levels of the value chain. In this first core project the main focus is on components and initial system level tasks. The first core project is divided into 4 divisions, which in turn comprise 3 to 5 work packages on related topics. A fifth, external division acts as a link to the parts of the Flagship that are funded by the member states and associated countries, or by other funding sources. This creates a collaborative framework for the entire Flagship.

This meta-analytical review focuses on the role of spatial ability when learning with pictorial visualizations. By means of selective theoretical review and meta-analysis (the latter regarding 27 different experiments from 19 studies), several sub-factors of spatial ability are considered as well as dynamic and non-dynamic, interactive and non-interactive visualizations. An overall effect of r=0.34 (95%-CI 0.28 to 0.39) demonstrating a medium advantage for high-spatial-ability learners when working with visualizations is calculated. More importantly, two moderators could be identified: Learners with low spatial ability can be significantly supported by a dynamic instead of a non-dynamic visualization as well as by 3d- instead of 2d-illustrations. Results are discussed in consideration of contemporary theories of multimedia learning. © 2010 Springer Science+Business Media, LLC.

ADAM17 has been molecularly cloned as the enzyme responsible for cleavage of the transmembrane protein TNFα (TNFα converting enzyme, TACE). Later it was realized that ADAM17 was also responsible for the processing of cell adhesion proteins, cytokine and growth factor receptors and many ligands of the EGF receptor. Since TNFα is a target of anti-inflammatory therapies, it was speculated that inhibition of ADAM17 might be a therapeutic strategy in the treatment of inflammation or inflammation associated cancer. Meanwhile it has been recognized that ADAM17 governs many vital functions in the body and loss of ADAM17 leads to severe defects in the skin and to high susceptibility of the intestine to inflammation. Here I summarize data on the physiologic role of ADAM17 and the feasibility of specific blockade of this enzyme. © 2013 Elsevier Ltd. All rights reserved.

The mining of huge databases of resting-state brain activity recordings represents state of the art in the assessment of endogenous neuronal activity-and may be a promising tool in the search for functional biomarkers. However, the resting state is an uncontrolled condition and its heterogeneity is neither sufficiently understood nor accounted for. We test the hypothesis that subjects exhibit unstable wakefulness, i.e., drift into sleep during typical resting-state experiments. Analyzing 1,147 resting-state functional magnetic resonance data sets, we revealed a reliable loss of wakefulness in a third of subjects within 3min and demonstrated the dynamic nature of the resting state, with fundamental changes in the associated functional neuroanatomy. Implications include the necessity of wakefulness monitoring and modeling, taking measures to maintain a state of wakefulness, acknowledging the possibility of sleep and exploring its consequences, and especially the critical assessment of possible false-positive or false-negative results. © 2014 Elsevier Inc.

The SYSCID consortium aims to develop a systems medicine approach for disease prediction in CID. We will focus on three major CID indications with distinct characteristics, yet a large overlap of their molecular risk map: inflammatory bowel disease, systemic lupus erythematodes and rheumatoid arthritis. We have joined 15 partners from major cohorts and initiatives in Europe (e.g.IHEC, ICGC, TwinsUK and Meta-HIT) to investigate human data sets on three major levels of resolution: whole blood signatures, signatures from purified immune cell types (with a focus on CD14 and CD4/CD8) and selected single cell level analyses. Principle data layers will comprise SNP variome, methylome, transcriptome and gut microbiome. SYSCID employs a dedicated data management infrastructure, strong algorithmic development groups (including an SME for exploitation of innovative software tools for data deconvolution) and will validate results in independent retrospective and prospective clinical cohorts. Using this setup we will focus on three fundamental aims : (i) the identification of shared and unique core disease signatures which are associated with the disease state and independent of temporal variation, (ii) the generation of predictive models of disease outcome- builds on previous work that pathways/biomarkers for disease outcome are distinct from initial disease risk and may be shared across diseases to guide therapy decisions on an individual patient basis, (iii) reprogramming disease - will identify and target temporally stable epigenetic alterations in macrophages and lymphocytes in epigenome editing approaches as biological validation and potential novel therapeutic tool. Thus, SYSCID will foster the development of solid biomarkers and models as stratification in future long-term systems medicine clinical trials but also investigate new causative therapies by editing the epigenome code in specific immune cells, e.g. to alleviate macrophage polarization defects.

Due to lack of targeted interventions, compliance issues, insufficient effect sizes and a high non-responder rate to currently available interventions, there is an urgent need to develop innovative and new interventions for chronic paediatric neuropsychiatric disorders, such as Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). Transcranial direct current stimulation (tDCS) has been shown to be an innovative, effective and safe alternative treatment approach for neuropsychiatric disorders in adults. Here, for the first time, the effect of tDCS on core neurocognitive and behavioral outcomes will be proven in children and adolescents. First, effect sizes and safety of standard tDCS in the clinical setting targeting core brain regions and disorder specific cognitive tasks will be established by three phase-IIa randomized, double blind, sham-controlled studies in ADHD and ASD. Second, the impact of brain development and age-dependent anatomical / functional features on effects of tDCS will be studied systematically using methods of modern neurophysiology, neuroimaging and electric current modeling. This involves an additional phase-I clinical trial. Third, mechanisms of tDCS on brain function will be studied, and biomarkers will be developed in order to predict individual response to standard and individualized stimulation protocols. Finally, the applicability of tDCS in children and adolescents will be improved by developing an innovative personalized home-based treatment option in combination with a telemental health service, which will be tested by a fifth, phase-IIa clinical trial. Throughout the entire project, ethical concerns of the target population will be addressed. This project opens a new avenue for the application of tDCS as an alternative treatment for a great number of chronic neuropsychiatric disorders in children and adolescents and will allow flexible integration of tDCS in the daily routine of families.
