A volume within the Subcellular Biochemistry series is an appropriate setting for the first multi-author book devoted to the new family of antioxidant and cell signalling proteins, the peroxiredoxins. Within the antioxidant and cell signalling fields, even the existence of the peroxiredoxins has yet to be appreciated by many; with this book we aim to rectify this situation. We have tried to select diverse chapter topics to cover relevant aspects of the subject and to persuade knowledgeable authors to contribute a manuscript. As almost inevitable, a few authors let us down by failing to respond, others could not submit a manuscript in time for personal reasons. These unfortunately were two of the pioneers, Earl Stadtman and Sue Goo Rhee, but we appreciate that they communicated a lot of details that helped us to reconstruct the early phase of peroxiredoxin enzymology. We have thus compiled a book that competently covers the peroxiredoxin field from its beginnings through to currently relevant topics. In the introductory Chapter 1 we provide a short historical survey of the subject, based upon the early structural and enzymic studies on peroxiredoxins, and then lead into some of our current personal interests, such as the likely continuing contribution of transmission electron microscopy (TEM) for the study of high molecular mass peroxiredoxin complexes and the association of peroxiredoxins with other proteins, and the targeting of drugs against microbial peroxiredoxins, as future therapeutic approaches.

In Inflammation in the Pathogenesis of Chronic Diseases: The COX-2 Controversy , a panel of leading experts chronicles the evidence supporting the roleofinflammationinthepathogenesisofmajorchronicdiseasesanddiscusses the current controversy regarding beneficial versus adverse effects of selective cyclooxygenase-2(COX-2)inhibitors.Expertsinmultipledisciplinesofmedical research provide exciting and enlightening perspectives on COX-2 and related molecular targets in the future of medicine. The book is broadly divided into fivesections. Webeginwithhistoricalperspectivesonthediscoveryanddev- opment of aspirin, ibuprofen, and compounds that selectively inhibit COX-2, including discussion of risk versus benefit and the potential for development of new compounds with better efficacy and safety in the 21st century. This is followed by a section illuminating the role of inflammatory mechanisms in the pathogenesisofarthritis,cardiovasculardisease,cancer,neurodegenerativedisease, diabetes mellitus, obesity, and other life-threatening and debilitating conditions.

It is more evident now than ever before that dynamic organization of human genome into nucleoprotein structure, chromatin confers the unique regulatory mechanisms for most of the cellular phenomena, which include replication, transcription, DNA repair, recombination and also apoptosis. The dynamic nature of the chromatin is regulated by chromatin modifications (epigenetic alterations), remodeling, histone chaperones and functional interactions of different chromatin interacting n- histone proteins. Dysfunction of this highly inter connected machineries disturb the cellular homoeostasis, and thereby causes several diseases. As we advance in our knowledge of chromatin function and also disease mechanisms in more details, their causal relationship is becoming more evident. This has lead to the identification of chromatin function as target for new generation therapeutics. In the light of these advances, it happens to be the right time to explore current insights into various aspect of chromatin and disease connection under one cover. Authors who are actively involved in chromatin research and have made several original contributions to develop latest paradigms in the field have written the chapters of this book. Significantly, the authors' repertoire is truly international. They come from eight different countries of Asia, Europe and America. The book has been divided into three different parts. Part I introduces the reader to the dynamic nature of chromatin structure and its link to diseases. First two chapters in this part deal with the chromatin architecture, chromatin dynamics in the cell cycle and molecular mechanism of chromatin remodeling.
