The book reviews the literature on the regulation of NADPH oxidase, which is controversial in many areas, and refers specifically to relevant publications from the past 4 years. Main topics are catalytical properties, cofactor requirements and structural components of NADPH oxidase, activation of NADPH oxidase, inhibition of NADPH oxidase, reconstitution and regulation of NADPH oxidase activity in cell-free systems, and pathology of NADPH oxidase.

Recent years have seen tremendous progress in the field of hormone action and consequent signal transduction. The 40th Colloquium Mosbach was devoted to the discussion of results concerning the molecular process of hormone action, especially the processes following hormone binding to the corresponding receptors. Structural and functional aspects of steroid hormone receptors as well as ion-channel-coupled and enzyme-linked receptors were treated in detail. Particular interest focussed on the latest results concerning transcriptional control, protein phosphorylation, the role of G-Proteins, oncogene proteins, involvement of phospholipases and the regulation of ion channels.
