Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review and identified five i...

BACKGROUND The new REACH legislation requires assessment of a large number of chemicals in the European market for several endpoints. Developmental toxicity is one of the most difficult endpoints to assess, on account of the complexity, length and costs of experiments. Following the encouragement of QSAR (in silico) methods provided in the REACH itself, the CAESAR project has developed several ...

Reproductive toxicity testing is one of the most complex, expensive and labor intensive fields of toxicology (Leist et al. drastically demonstrate the fundamental importance of reliable developmental toxicity tests for human safety (van Recently, human embryonic stem cell based in vitro test systems have been established that recapitulate critical periods of human early development (Krug et al....

In response to the US EPA HPV Challenge Program, this study was conducted to: (1) evaluate the relationship between PAC content and the developmental toxicity of high-boiling petroleum substances (HBPS) and (2) develop mathematical models to predict the developmental toxicity of similar untested substances based on their aromatic ring class (ARC) profiles. For this investigation, 68 development...

1. In Copenhagen in June 1995, an OECD Working Group on Reproduction and Developmental Toxicity discussed the need to update existing OECD Test Guidelines for reproduction and developmental toxicity and the development of new Guidelines for endpoints not yet covered. The Working Group recommended that the Guideline for Developmental Toxicity should be revised, based on a proposal received from ...
