Announcement FOURTH INTERNATIONAL MEETING ON BIOLOGICAL REACTIVE INTERMEDIATES
The University of Arizona Center for Toxicology will be hosting the Fourth International Meeting on Biological Reactive Intermediates, Jan 14-17,1990, at the Doubletree Hotel in Tucson, AZ. The purpose of these continuing symposia on biological reactive intermediates is to further the understanding of the mechanisms underlying the toxicity and carcinogenesis of environmental chemicals. The goal of the fourth meeting is to explore the molecular and cellular consequences of the intracellular formation of reactive intermediates. Particular emphasis will be placed on identification of specific molecular targets for reactive intermediates and the events that are triggered as a result of their interaction with these targets. Because reactive intermediates may modulate cell-cell interactions, and because they may travel from organ to organ, specific sessions are included to address these topics. The meeting will end with discussions of the impact of reactive intermediates on human health. For further information, please contact I. Glenn Sipes, Ph.D., Department of Pharmacology and Toxicology, College of Pharmacy, University of Arizona, Tucson, AZ 85721.
