Aim of the study: Apart from empirically learned medicinal and pharmacological properties, the selection of medicinal plants is dependent on cognitive features, ecological factors and cultural history. In literate societies the transmission of medicinal plant knowledge through texts and, more recently, other media containing local as well as non-local knowledge has a more immediate and a more prolonged effect than oral transmission. Therefore, I try to visualize how field based studies in ethnobiology and especially medical ethnobotany and ethnopharmacology run the risk of repeating information and knowledge and illustrate the importance of differentiating and acknowledging the origin, transmission and rationale of plant use made by humans. Materials and methods: Reviewing literature dealing with the traditional parameters (e.g. hot/cold dichotomy, organoleptic properties, doctrine of signatures) influencing the selection and transmission of plant use in a juxtaposition to our recent finding of causal influence of text on local plant use. Discussing the passing down of knowledge by text as a special case of oblique/one-to-many knowledge transmission. Results: Historical texts on materia medica, popular books on plant use, clinical studies, and informants of ethnobotanical field studies generate a circle of information and knowledge, which progressively conditions the results of ethnobotanical field studies. While text reporting on phytotherapeutical trends may cause innovation through the introduction of "new" applications to local customs, persistently repeating well established folk remedies leads to the consolidation of such uses adding a conservative dimension to a local pharmacopoeia, which might not actually be there to that extent. Conclusions: Such a "shaping" of what might appear to be the results of a field investigation is clearly outside the ordinary principles of scientific enquiry. The traditional pillars of ethnobotanical field studies - that is, "input to drug discovery" and "conservation of cultural heritage" - are also incompatible with this process. Ethnobotancial field studies aimed at a contribution to natural products research and/or the conservation of cultural heritage, as well as those aimed at an assessment and validation of local pharmacopoeias should differentiate between local plant use and widespread as well as modern knowledge reported in popular textbooks and scientific literature. © 2011 Elsevier Ireland Ltd.

Consumption of synthetic mind-altering compounds, also known as "new psychoactive substances," is increasing globally at an alarming rate. Synthetic cannabinoids (SCs) are among the most commonly used new psychoactive substances. They are usually purchased as marijuana-like drugs, marketed as herbal blends and perceived as riskfree by inexperienced users. Yet, contrary to Δ9-tetrahydrocannabinol, SCs may lead to severe health consequences, including anxiety, tachycardia, hallucinations, violent behavior, and psychosis. This review focuses on the latest (2010-2015) evidence of psychotic symptoms induced by ingestion of products containing SCs. Reports suggesting that SCs may either exacerbate previously stable psychotic symptoms (in vulnerable individuals) or trigger new-onset psychosis (in individuals with no previous history of psychosis) are reviewed. Pharmacology and toxicology of these compounds are discussed, with particular reference to their psychoactive effects. © 2016 Society of Biological Psychiatry.

FLOWERED objective is to contribute to the development of a sustainable water management system in areas affected by fluoride (F) contamination in water, soils and food in the African Rift Valley countries (Ethiopia, Kenya, Tanzania), thus to improve living standards (environmental, health and food security) of its population. FLOWERED aims to study, test and implement innovative defluoridation technologies for drinking and irrigation water that will mainly operate at small village scale and to develop an integrated, sustainable and participative water and agriculture management at a cross-boundary catchment scale. On the basis of the complexity of the issue of water de-fluoridation, the proposed scientific approach in FLOWERED is based on a detailed knowledge of the geological and hydrogeological setting that controls contamination of water that constitute the prerequisite for the implementation of a sustainable water management and for the proposal of sustainable and suitable strategies for water sanitation and agricultural system. Innovative agricultural practices will be assessed, aiming to mitigate the impacts of F contamination of water and soil on productivity of selected food and forage crops and dairy cattle health and production. The development of an innovative and shared Geo-data system will support the integrated, sustainable and participative management system. FLOWERED, focusing on innovative technologies and practices and taking into account local experiences, will implement an integrated water and agriculture management system and will enable local communities to manage water resources, starting from using efficient defluoridation techniques and applying sustainable agricultural practices. The integrated approaches improve knowledge for EU partners, local researchers, farmers and decision makers. The Project through the involvement of SMEs will strengthen the development co-innovative demonstration processes as well as new market opportunities.

In the Roadmap for Mental Health and Wellbeing Research in Europe (ROAMER), top-priority is research into child and adolescent mental health symptoms. CAPICE (Childhood and Adolescence Psychopathology: unravelling the complex etiology by a large Interdisciplinary Collaboration in Europe) will address this priority. This network will elaborate on the EArly Genetics and Lifecourse Epidemiology (EAGLE) consortium, a well-established collaboration of the many European birth and adolescent population based (twin and family) cohorts with unique longitudinal information on lifestyle, family environment, health, and emotional and behavioral problems. Phenotypic and genome-wide genotypic data are available for over 60,000 children, in addition to genome-wide genotypes for over 20,000 mothers and epigenome-wide data for over 6,000 children. Combined with the enormous progress in methodology, the results of the research performed in this network will greatly expand our knowledge regarding the etiology of mental health symptoms in children and adolescents and shed light on possible targets for prevention and intervention, e.g. by drug target validation. Moreover, it will provide Early Stage Researchers (ESRs) with an excellent training in the psychiatric genomics field given by a multidisciplinary team of eminent scientists from the academic and non-academic sector highly experienced in e.g., gene-environment interaction and covariation analyses, (epi)genome-wide association studies, Mendelian Randomization (MR) and polygenic analyses. With a focus on common and debilitating problems in childhood and adolescence, including depression, anxiety and Attention Deficit Hyperactivity Disorder, CAPICE will contribute to improving later outcomes of young people in European countries with child and adolescent psychopathology.

ICT is embedded and pervasive into our daily lives. The notion of Cyber Physical Systems (CPS) has emerged: embedded computational collaborating devices, capable of controlling physical elements and responding to humans. The Cross-layer modEl-based fRamework for multi-oBjective dEsign of Reconfigurable systems in unceRtain hybRid envirOnments (CERBERO) project aims at developing a design environment for CPS based of two pillars: a cross-layer model based approach to describe, optimize, and analyze the system and all its different views concurrently; an advanced adaptivity support based on a multi-layer autonomous engine. To overcome the limit of current tools, CERBERO provides: libraries of generic Key Performance Indicators for reconfigurable CPSs in hybrid/uncertain environments; novel formal and simulation-based methods; a continuous design environment guaranteeing early-stage analysis and optimization of functional and non-functional requirements, including energy, reliability and security. CERBERO effectiveness will be assessed in challenging and diverse scenarios, brought by industrial leaders: an embedded CPS with self-healing capabilities for planetary explorations (TASE-S&T), an ocean monitoring CPSoS (AS), and a Smart Travelling CPSoS for Electric Vehicle (TNO-CRF-S&T). CERBERO will automate multi-objective decisions to meet requirements and correct/optimizedbyconstruction designs. Interoperable components (i.e. DynAA by TNO, AOW by IBM, PREESM by INSA, PAPI-ARTICo3 by UPM, MDC by UniCA-UniSS) will be enhanced with additional features (as security, USI), mostly released as open-source to foster open innovation and a real path to standardisation, and integrated (IBM- AI) into a unique framework. Design speed up (one order of magnitude), increased performance (30% less energy) and reduced costs of deployment (by rapid prototyping and system in the loop incremental design) and maintenance (by runtime verification and adaptivity) of CPSoS are expected.

The number of biobanks for diagnostic/clinical/biodiversity preservation purposes is increasing exponentially, representing an economic burden for the EU. Cryopreservation (Liquid Nitrogen LN) is the only cells/gametes long-term repository method. LN storage is expensive though, requires dedicated facilities, is hazardous, carries pathogens and has high carbon footprint. DRYNET objective is to set an inter-sectorial/multidisciplinary/international network between EU academic (5), SME (3), the EU pan-Biobank, and international partners (Japan/Thailand), with the aim of sharing knowhow & expertise to lay down the theoretical and early empirical basis for the dry storage of cells/germplasm. DRYNET merges the partners expertise, theoretical/ biophysical/ mathematical modelling, cellular/ molecular/ insect biology, embryology, mechanical engineering into a coherent approach towards dry storage of cells/germplasm. International/inter-sectorial secondments, with meeting/workshop/summer school will be primary tools to implement our strategy for biobanking. Outreaching activities will guarantee public awareness of the project. DRYNETs relies on water subtraction to induce a reversible block of metabolism, a survival strategy available in nature (anhydrobiosis). The work plan foresees the exploitation of natural xero-protectants (Late Embryogenesis Abundant proteins), loaded/expressed in gametes/cells, before drying. The best drying approaches, supported by theoretical/biophysical/math modelling, will be implemented by SMEs/academy partners. DRYNET will bring a simplification of currents practices, with cost and carbon footprint reduction, for the maintenance/shipping of biobanks. DRYNET will generate young scientists with transferable skills, ensuring career prospect in academia/industry. DRYNET strengthens the international/sectorial network between different disciplines, ensures long-term sustainability of the project, and boosts European competitiveness in biobanking.
