Regarding the References for Reference Chemicals of Alternative Methods

March 18, 2019
The selection of reference and proficiency chemicals is an important component of method validation and proficiency evaluations. Reference chemicals are a set of test substances used by a method developer to evaluate there liability and relevance of a new method, in comparison to reference data (usually to a validated reference method). Proficiency chemicals, as defined in OECD Guidance Document on Good In Vitro Method Practices, are defined post validation as a subset of the reference chemicals, or other chemicals with...

Increased Throughput and Cryopreservation of Precision-cut Lung Slices Extend the Utility of Human-relevant, 3-Dimensional Pulmonary Test Systems

March 18, 2019
Human-relevant, in vitro/ex vivo assays are considered an ethical and economically viable manner by which to screen the thousands of chemicals requiring hazard assessment. Of the 3-dimensional models, human precision-cut lung slices (PCLS) are often considered the most physiologically relevant pulmonary test system, but lower throughput and difficulties in cryopreservation have hampered PCLS use. We have modified a tissue slicer to accommodate 3 tissue cores for simultaneous slicing. Increased slice production was quantified using agarose and tissue cores in the slicer....

Next Generation Tobacco Products and Skin Staining

March 18, 2019
Next generation tobacco and nicotine products (NGPs) such as electronic cigarettes (EC) and tobacco heating products (THP) have reduced toxicity and hold great potential for reducing the risks associated with cigarette smoking. NGPs may also have hygiene benefits for consumers that switch to these products. In this study, the level of skin staining was assessed following exposure to a scientific reference cigarette (3R4F) and NGPs across the risk continuum; a prototype EC or a commercial THP (glo™). Test articles (TAs) were...

Australian Bill Passed to End Animal Testing for Cosmetics

February 21, 2019
Measures outlined in the Industrial Chemicals Bill 2017, passed by the Australian senate on 19 February, 2019, will apply to both imported and Australian produced chemicals for use as cosmetic ingredients. The commencement date is set for July 2020 although it is believed that the cosmetics industry will not need an entire year to implement changes to comply with the new law. Additionally, the bill includes funding for the development of alternative test methods. Read the full article....
