Deliverable 10.3 - Plan for the dissemination and exploitation of the results from EuroMix

This plan for the dissemination and exploitation of the results (PEDR) provides the basis for EuroMix dissemination and exploitation activities by (i) outlining the EuroMix dissemination, communication, and exploitation strategy and by (ii) defining the timeframe, roles and responsibilities of these activities. The PEDR includes information regarding; dissemination channels, timelines, exploitation roadmaps and beneficiaries responsibilities. This will allow for the systematic implementation of the EuroMix exploitation and dissemination strategy throughout the project and will maximise the impact by implementing a coherent plan for the dissemination and exploitation of the project's results during and after the project. The first version of the PEDR was finalised in October 2016, after this it will be reviewed and updated annually as the project progresses. The final version will provide a long-term strategy for post-project dissemination and exploitation that will allow the European Commission (EC) to assess the impact of the project

Diverse roles of androgen receptor (AR) domains in AR-mediated signaling

Androgens control male sexual development and maintenance of the adult male phenotype. They have very divergent effects on their target organs like the reproductive organs, muscle, bone, brain and skin. This is explained in part by the fact that different cell types respond differently to androgen stimulus, even when all these responses are mediated by the same intracellular androgen receptor. To understand these tissue- and cell-specific readouts of androgens, we have to learn the many different steps in the transcription activation mechanisms of the androgen receptor (NR3C4). Like all nuclear receptors, the steroid receptors have a central DNA-binding domain connected to a ligand-binding domain by a hinge region. In addition, all steroid receptors have a relatively large amino-terminal domain. Despite the overall structural homology with other nuclear receptors, the androgen receptor has several specific characteristics which will be discussed here. This receptor can bind two types of androgen response elements (AREs): one type being similar to the classical GRE/PRE-type elements, the other type being the more divergent and more selective AREs. The hormone-binding domain has low intrinsic transactivation properties, a feature that correlates with the low affinity of this domain for the canonical LxxLL-bearing coactivators. For the androgen receptor, transcriptional activation involves the alternative recruitment of coactivators to different regions in the amino-terminal domain, as well as the hinge region. Finally, a very strong ligand-induced interaction between the amino-terminal domain and the ligand-binding domain of the androgen receptor seems to be involved in many aspects of its function as a transcription factor. This review describes the current knowledge on the structure-function relationships within the domains of the androgen receptor and tries to integrate the involvement of different domains, subdomains and motifs in the functioning of this receptor as a transcription factor with tissue- and cell-specific readouts

The MCRA toolbox of models and data to support chemical mixture risk assessment

A model and data toolbox is presented to assess risks from combined exposure to multiple chemicals using probabilistic methods. The Monte Carlo Risk Assessment (MCRA) toolbox, also known as the EuroMix toolbox, has more than 40 modules addressing all areas of risk assessment, and includes a data repository with data collected in the EuroMix project. This paper gives an introduction to the toolbox and illustrates its use with examples from the EuroMix project. The toolbox can be used for hazard identification, hazard characterisation, exposure assessment and risk characterisation. Examples for hazard identification are selection of substances relevant for a specific adverse outcome based on adverse outcome pathways and QSAR models. Examples for hazard characterisation are calculation of benchmark doses and relative potency factors with uncertainty from dose response data, and use of kinetic models to perform in vitro to in vivo extrapolation. Examples for exposure assessment are assessing cumulative exposure at external or internal level, where the latter option is needed when dietary and non-dietary routes have to be aggregated. Finally, risk characterisation is illustrated by calculation and display of the margin of exposure for single substances and for the cumulation, including uncertainties derived from exposure and hazard characterisation estimates.</p

Overview on legislation and scientific approaches for risk assessment of combined exposure to multiple chemicals: the potential EuroMix contribution

This article reviews the current legislative requirements for risk assessment of combined exposure to multiple chemicals via multiple exposure routes, focusing on human health and particularly on food-related chemicals. The aim is to identify regulatory needs and current approaches for this type of risk assessment as well as challenges of the implementation of appropriate and harmonized guidance at international level. It provides an overview of the current legal requirements in the European Union (EU), the United States and Canada. Substantial differences were identified in the legal requirements for risk assessment of combined exposure to multiple chemicals and its implementation between EU and non-EU countries and across several regulatory sectors. Frameworks currently proposed and in use for assessing risks from combined exposure to multiple chemicals via multiple routes and different durations of exposure are summarized. In order to avoid significant discrepancies between regulatory sectors or countries, the approach for assessing risks of combined exposure should be based on similar principles for all types of chemicals. OECD and EFSA identified the development of harmonized methodologies for combined exposure to multiple chemicals as a key priority area. The Horizon 2020 project “EuroMix” aims to contribute to the further development of internationally harmonized approaches for such risk assessments by the development of an integrated test strategy using in vitro and in silico tests verified for chemical mixtures based on more appropriate data on potential combined effects. These approaches and testing strategies should be integrated in a scientifically based weight of evidence approach to account for complexity and uncertainty, to improve risk assessment

Supporting patients with low health literacy: what role do radiation therapists play?

Purpose: Health literacy plays a key role in a patient’s ability to use health information and services, and can affect health outcomes. This study aimed to explore radiation therapists’ perspectives on how they support people with lower health literacy who are undergoing radiotherapy. Methods: Semi-structured interviews were conducted with 25 radiation therapists working in radiation oncology departments in New South Wales, Australia. Results: The four key themes were (1) the process of identifying a patient with low health literacy, (2) the perceived consequences of low health literacy, (3) managing and responding to the needs of different health literacy groups and (4) recommendations to address low health literacy in radiotherapy. Radiation therapists appeared to make an informal, intuitive judgment about a patient’s health literacy, using a variety of verbal and non-verbal cues as well as impromptu conversations with the multi-disciplinary team. Patients perceived to have lower health literacy were described as having greater difficulties assimilating knowledge and engaging in self-care. Although participants reported communicating to patients at a basic level initially, they subsequently tailored their communication to match a patient’s health literacy. Strategies reported to communicate to low health literacy groups ranged from using lay language with minimal medical terminology, using visual aids (photos), using analogies, reiterating information and asking family members with higher literacy to attend consultations. Conclusion: A more structured approach to supporting patients with low health literacy and integrating health literacy training in radiation oncology departments may help to minimise the adverse outcomes typically experienced by this population

Woodrow Wilson’s diplomatic agenda and strategic military interventions: how they affected the Russian Civil War 1918-1920

This thesis aims to understand the factors that affected Woodrow Wilson’s foreign and military policy actions, which subsequently led to decisions that dictated United States’ intervention into the Russian Civil War, 1918-1920. The background information discussed demonstrates the importance of the Russian Civil War. This chaotic time in history surrounding World War I caused much of Woodrow Wilson’s dilemma and consequentially changed future of Soviet-American relations. It details how it would take numerous foreign policy shifts to convince Mr. Wilson to send U.S. troops to intervene into North Russia and Siberia. Lenin’s opposing perspective will encompass what is contained in much of the supporting information surrounding this thesis. In conjunction with military operations there, the allies attempted to broker peace with Lenin and the Bolsheviks in the form of the Prinkipo Proposal, the Bullitt Mission, and the Hoover-Nansen Proposal. The concluding question that frames the argument of this research will answer what happened because Wilson intervened on Russian soil and how it affected the Communist world revolution. What positive results, if any, can be discovered? (Author abstract)Rinehart, R.A.
