In September 2006 the 2nd International Conference on Paraoxonases took place in Hajdúszoboszló, Hungary, bringing together the world's foremost experts in the field. The current book is a distillation of the plenary lectures which took place at the meeting, resulting in a comprehensive up-to-date, state-of-the-art review of current paraoxonase research. The book details a unique and novel enzyme whose physiological/pathological function(s) are just starting to be revealed.
