BelTox organized its 3rd Advanced Toxicology Course, this time focusing on reproductive toxicology and embryo-fetal toxicology in particular at the Elewijt Center on October 13th. This course must be called a great success. There were a lot of participants (31) some of which came from as far as Luxemburg, Germany, Switzerland and Finland and the speakers were all of very high quality. Certainly the presentations of Steven Van Cruchten (embryonal development) and Graham Bailey (interpretation of embryo-fetal toxicity studies) made a great impression. The exercise in the afternoon was very well set up and all participants engaged with a lot of enthusiasm. The Elewijt centre once again proved to be an ideal place to organize such events.
