This volume is the selected, edited proceedings of the International Taurine Sympo- th sium held in Tucson, Arizona, in July 1997. The meeting was a satellite symposium ofthe 16 Biennial Meeting of the International Society for Neurochemistry, which was held in Boston immediately following the Tucson meeting. In view of the desert location of Tucson, the meeting was advertised tongue-in-cheek as being the hottest scientific meeting ever. As the weather lived up to its billing, the Symposium may well have earned the title. The meeting was held in an atmospheric cluster of adobe buildings, old by the stan- dards of the American southwest, at the Westward Look Resort in the Sonoran Desert foot- hills of Tucson, which is overlooked by the 9000' high Santa Catalina mountains. As is the norm for taurine symposia, participants formed a multinational group, with representatives from China, Korea, Japan, United States, Mexico, Venezuela, Ireland, England, Spain, Italy, Finland, France, Denmark, Germany, Norway and Armenia. The meeting was organized around plenary lectures by Russell Chesney (University of Tennessee: Taurine and infant nutrition), Herminia Pasantes-Morales (National Autono- mous University of Mexico: Taurine: An osmolyte in mammalian tissues) and Kinya Kuri- yama (Kyoto Prefectural University of Medicine: Interrelationship between taurine and GABA).
