AOP NEWS – October 2018
- AOP Training:
- A for-credit graduate-level summer course on AOP development was offered to students from the University of Ottawa, Carleton University, University of Alberta and University of Laval as part of the NSERC CREATE-REACT program (www.create-react.uottawa.ca). This was the second year that this course has been offered, with plans to offer it again in the summer of 2019.
.Contact: Jason Obrien <jason.obrien@canada.ca> - There was a recent AOP Training Session in the Continuing Education afternoon of the 2nd Asian Congress on Alternatives meeting in Guangzhou, China on October 9, 2018, which was organised and sponsored by the Humane Society The session was attended by ca. 50 mostly Chinese students and young scientists. Kate Willett from the Humane Society gave an introduction to the AOP concept, while Clemens Wittwehr from the European Commission's JRC showed the AOP Wiki and how AOP knowledge can be searched and entered there. It became clear that training efforts to Chinese stakeholders can only be meaningfully stepped up through a local group of "AOP ambassadors". Measures need to be discussed to create such a group and support it in their local training activities.
- A training session on creating quantitative AOPs with Effectopedia was held as a at Eurotox 2018 in Brussels. . Training materials can be found at https://www.effectopedia.org/eurotox2018/
- Training and practice sessions for quantitative AOPs will be presented at the School of Environmental Engineering, University of Seoul18-23 Nov 2018. cContact: Hristo Aladjov <hristo.aladjov@effectopedia.org>

- New Tool Development:
- There is a new tool in development that will compile lists of chemical stressors associated with AOPs in the AOP-KB. The tool is being developed as macro-enabled spreadsheets that uses the AOP Event ontology to search (what) for chemicals that likely to activate an AOP.Webinars for this tool are anticipated in late 2018 or early 2019. Contact: Nancy Baker Baker.nancy@epa.gov
- A new tool, Bayesian Inference for Substance and Chemical Toxicity (BISCT) has been released. It contains a simple user interface for predicting impact of chemicals on steatosis and steroidogenesis AOP networks using active or inactive calls for MIE or KE from in vitro assay measurements.The tool can be downloaded from: https://github.com/DataSciBurgoon/bisct . Contact: Lyle.L.Burgoon@usace.army.mil
- AOP Handbook Team: The AOP Handbook team has been actively reviewing the current status of AOP development and is building ideas for future revisions. These include trying to solve the ongoing lack of interest in developing new AOP due to the large time commitment, ownership issues, and problems with partial AOPs that are never developed further. They are suggesting changes to the review process, KE sharing, using the KER as the “pragmatic” unit of reporting, and holding future workshops on major KEs such as oxidative stress. A report out on activities is planned for the December EAGMST conference call. Contact: Magda Sachana Magdalini.SACHANA@oecd.org
- Call For Proposals:The JRC has released a call for proposals for a study entitled “Retrospective and Prospective Analysis of the AOP Framework - Spotlight on the AOP knowledge users”. The purpose of this study is to retrospectively and prospectively analyse the AOP Framework's past, present and future in terms of its suitability to achieve the ultimate goal of better regulatory decisions. The study will also deliver actionable suggestions to increase the uptake of the AOP Framework in the relevant stakeholder communities, which will be shared and subsequently co-executed with the AOP Framework governance bodies at OECD and other organisations.
