With the help of many colleagues from all over the world, the organizing committees has developed an exciting scientific programme that includes 5 selected plenary lectures, 18 symposia with 36 State-of-the-Art lectures and 72 symposium communications, plus 2 wine and cheese poster sessions. We strongly appreciate the help of the symposium organizers. Because we believe that a Society like ours must prepare the future, a strong effort has been made to encourage the participation of students and post-docs by providing free or reduced registration, and offering as many travel grants as possible. We have also organized a Young Investigator symposium as an integral part of the scientific programme, offering junior colleagues a unique opportunity to present their work. This effort towards the young generation would not have been possible without the strong support of the University of Rennes 1, but also many local, national and international bodies, scientific societies and private companies (see left page). We are extremely grateful for this. We look forward to seeing you here in Rennes for a fruitful scientific meeting, friendly networking and an enjoyable stay in the capital of Brittany.
