Download or read book OECD Guidelines for the Testing of Chemicals Section 4 Test No 442E In Vitro Skin Sensitisation In Vitro Skin Sensitisation assays addressing the Key Event on activation of dendritic cells on the Adverse Outcome Pathway for Skin Sensitisation written by OECD and published by OECD Publishing. This book was released on 2024-06-25 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present Key Event based Test Guideline (TG) addresses the human health hazard endpoint skin sensitisation, following exposure to a test chemical. Skin sensitisation refers to an allergic response following skin contact with the tested chemical, as defined by the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS). This TG is proposed to address the activation of dendritic cells, which is one Key Event on the Adverse Outcome Pathway (AOP) for Skin Sensitisation. It provides four in vitro test methods addressing the same Key Event on the AOP: (i) the human cell Line Activation Test or h-CLAT method, (ii) the U937 Cell Line Activation Test or U-SENS, (iii) the Interleukin-8 Reporter Gene Assay or IL-8 Luc assay and (iv) the Genomic Allergen Rapid Detection for assessment of skin sensitisers (GARDTMskin). All of them are used for supporting the discrimination between skin sensitisers and non-sensitisers in accordance with the UN GHS. The test methods described in this TG either quantify the change in the expression of cell surface marker(s) CD54 and CD86, the cytokine IL-8, or a series of genes (genomic biomarker signature) that are associated with the process of activation of monocytes and DC following exposure to sensitisers.

This book was released on 2023-07-04 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Defined Approach (DA) consists of a selection of information sources (e.g in silico predictions, in chemico, in vitro data) used in a specific combination, and resulting data are interpreted using a fixed data interpretation procedure (DIP) (e.g. a mathematical, rule-based model). DAs use methods in combination and are intended to overcome some limitations of the individual, stand-alone methods.

Download or read book European Partnership on the Assessment of Risks from Chemicals PARC Focus on New Approach Methodologies NAMs in Risk Assessment written by Terje Svingen and published by Frontiers Media SA. This book was released on 2024-08-21 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: The European Partnership on the Assessment of Risks from Chemicals (PARC) project was launched in 2022. The overarching aim of this partnership is to enhance our knowledge about chemical substances to better safeguard human health and the environment against harmful effects. The project will run for seven years under Horizon Europe. PARC is subdivided into several work packages (WPs). WP5 is focused on hazard assessment for human and environmental health and includes more than 80 partners across Europe. WP5 aims to fill data gaps for specified chemical substances of concern (e.g, bisphenol alternatives) and to develop or improve new approach methodologies (NAMs) for chemical hazard assessment. This is in order to progress towards a risk assessment paradigm relying less on animal toxicity data, both with respect to human health and environmental safety. As the PARC initiative will evolve over time with respect to both projects and activities, presenting early initiatives will foster an increased awareness of ongoing activities and potential incorporation of new activities going forward.

Download or read book A Practical Guide to Toxicology and Human Health Risk Assessment written by Laura Robinson and published by John Wiley & Sons. This book was released on 2018-11-05 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Toxicology – the study of the adverse effects of chemicals on living organisms is the cornerstone to all aspects of chemical safety and knowledge of the subject is needed in a wide spectrum of fields from the chemical industry to medicine, emergency services, forensics, and regulatory science. Toxicology involves the study of symptoms, mechanisms, treatments and detection of poisoning ... especially the poisoning of people. The many problems arising from a poor understanding of toxicology and its applications in hazard communication and chemical safety motivated the author's training courses and webinars, leading to this valuable book. Providing a practical and accessible guide, A Practical Guide to Toxicology and Human Health Risk Assessment enables readers to quickly build up knowledge and understanding of toxicology and its use in hazard identification, which is a fundamental part of chemical risk assessment. The book also covers current toxicological testing strategies and the use of physicochemical test data in hazard identification and exposure assessment. Examples are provided throughout the book to highlight important issues along with a summary of the key points that have been covered in each of the respective chapters. The book concludes with a listing of online resources on toxicology and risk assessment.
