OpenTox 2022 Virtual Conference 

Session 16 Summary 

  • Welcome to the session and Introduce by Fred Klaessig and his connection to Nanoinformatics (co-editor with Andrea Haase of EU-US 2030 Roadmap)
  • Connect the NanoInformatics session to earlier talks (Egon Willighagen and eNanoMapper on the first day and Shareen Doak with NAMs on the third day of OpenTox 2022)
  • Nanomaterials are chemicals in particulate form, which means understanding their toxicological profiles has the added challenge of connecting studies in physico-chemical characterization (work by people like Fred Klaessig) with those conducting toxicity studies (work by people like Shareen Doak and NAMs).
  • Effectively, physical chemistry studies will be re-purposed as in the GRACIOUS Framework, where particle dissolution and solubility become criteria for selecting toxicity endpoints, which in turn become involved with grouping particles according to similarity.
  • With re-purposing, we move from the R of FAIR (reproducibility) to the I (interoperability), and this means we must consider other uses of our data when generating datasets, e.g. selection of metadata.
  • Today’s three speakers address each of these points:
  • Nastassja Lewinsski in applying natural language techniques to curate journal articles by computers rather than done manually;
  • Antreas Afantitis in developing a suite of computational models that can be utilized in grouping or in predictive toxicology;
  • Barry Hardy in highlighting the infrastructure that has been formalized through the NanoCommons project.
