Book Description
Since the discovery of technetium (in 1937, by Perrier and Segre), technetium-99 and technetium-99m have become most familiar in the specialised literature, the behaviour of the former being of concern regarding its health impact, the latter having been used intensively in medical tests for many years. The knowledge of the characteristics and behaviour of this element in nature is currently increasing exponentially. It has become clear, however, that there is still a serious shortage of information needed to assess properly its burden and impact on man and his environment. Technetium may indeed be released from nuclear installations or as a waste product from medical applications. It is generally considered to be highly mobile as the anion TcOi, but it is also suspected to be readily reduced in soils and metabolised in living beings into lower oxidation states. The seminar was planned to analyse thoroughly the experimental results obtained up to now and to make recommendations of specific issues requiring further research. This book presents the papers of the different sessions in the order of presentation, and the conclusions drawn by three discussion groups which dealt separately with: problems of sources and distribution of man-made technetium and its radiological consequences; the chemical behaviour of technetium in different ecosystems; biochemical reactions and binding with macromolecules in various life systems. vi Preface The editors, together with the Programme Committee of the Seminar, wish to express their gratitude to the chairmen of the different sessions for their summary of the group discussions.

Book Description
The papers in this book, illustating the present status of knowledge related to the vacuolar compartment of fungi and plants, were presented at an Advanced Research Workshop entitled "Plant Vacuoles. Their Importance in Plant Cell Compartmentation and their Applications in Biotechnology" held in Sophia-Antipolis, France, on July 6-11, 1986. The organizers were fortunate in being able to assemble representative leaders of all the above fields of research concerning this compartment. These scientists from all over the world were invited to present their latest results and to exchange views and plans for continued research in this highly exciting field, which is very important for the improving the industrial aspect of plant biotechnology related to the production of molecules with a high added value. To ensure maximal flexibility and opportunity for dicussion, the chairmen of the various sessions were asked to introduce their respective topics, after which they were given the freedom of organizing their sessions in a more or less improvised fashion, with brief presentations of relevant new information by participants following a schedule fixed relatively shortly before the workshop. This procedure proved to be highly successful, giving rise to most productive and stimulating discussions among the representatives of the various fields.
