Perspective in Comparative Endocrinology: Unity and Diversity  Sorrento (Napoli), Italy, May 26-30, 2001 ***CDROM***

Foreword

By decision of International Federation of Comparative Endocrinology Societies (IFCES), the meeting in Sorrento (Napoli) was designated as the XIV International Congress of Comparative Endocrinology (ICCE). It has been my honor to chair this Congress for three main reasons to be equally considered: it is the first ICCE of the third millennium, pursuing tradition; the scientific organization has been chaired by Henk Goos (University of Utrecht, The Netherlands), thus the Congress should be considered patrimony of the new born European Nation; the Congress has been held in honor of Giovanni Chieffi, mentor of Italian comparative endocrinologists. His outstanding results are recognized all over the world and he strongly has contributed and contributes to affirm the fascinating idea of comparative studies in biology as the unity (representing the common origin of genes, structures, processes) and the mode things have evolved in different ways, leading diversity. Therefore, in accordance with Henk Goos, the motto of the Congress was "Unity and Diversity" and has been chosen as part of the title of this volume.

Special thanks go to Rakesh Rastogi, for his competence and for the hard work carried out during the organization of the scientific sessions, and to Hubert Vaudry, President of the IFCES during 1997-2001, for useful criticisms. I’m also grateful to the Second University of Napoli (SUN), the University of Napoli "Federico II", the Department of Human Physiology and Integrative Biology "Filippo Bottazzi" (now Department of Experimental Medicine, SUN), Carl Zeiss S.p.A. and Casa Editrice EdiSES for financial support.
