Direct methods of crystal structure determination are usually associated with techniques in which phases for a set of structure factors are determined from the corresponding experimental amplitudes by probabilistic calcula tions. It is thus implied that such ab initio phase calculations do not require a knowledge of atomic positions, and this basis distinguishes direct methods from other techniques for structure determination. An acceptably wider interpretation of the term direct methods leads to other important applica tions involving, inter alia, the use of heavy atoms, resolution-limited phase data for large molecules, rotation functions, and Fourier series. These topics are discussed in the later chapters of this book. Although some earlier theoretical investigations were made by Harker and Kaspar, direct methods may be considered to have begun around the year 1950. Important landmarks in the development of the subject include the book by Hauptmann and Karle, The Centrosymmetric Crystal (1953), the definitive paper by Karle and Karle in Acta Crystallographica (1966), and the recent (1978) sophisticated program package MULTAN 78 produced mainly by Germain, Main, and Woolfson. Woolfson's book, Direct Methods in Crystallography, was published in 1961, but because of the rapid progress in direct methods, much of it soon became outmoded. It is interesting to note that direct methods nearly came into being many years earlier. Certainly the E2 relationship was used implicitly by Lonsdale in 1928 in determining the crystal structure of hexamethylbenzene.

The current book attempts to give a glimpse of the scientific life of Michael Rossmann. The book begins with his very interesting and moving autobiography. His enormous energy must have been evident already from early childhood when he and his mother had to emigrate from Nazi-Germany to England, via The Netherlands. Starting school with a new language was a challenge that he managed well with the assistance of understanding teachers. Crystallography soon became the tool to explore new worlds, unknown to everybody. With a skill for mathematics, he realized that the transform of a molecular structure in the diffraction pattern could be used for analysis of both symmetry and structural relationships. This method, molecular replacement (MR, also the initials of his name) became one of his great successes of his career. The previous book by him in this series (Selected Papers by Michael G Rossmann with Commentaries) covers his main contributions in this area.With an interest in symmetry, viruses became obvious objects to study. Rossmann attacked these monstrously large molecular assemblies with his unfailing energy and his appetite for real challenges. The amazing variation of molecular arrangements with icosahedral symmetry is truly amazing. This book includes a selection of reports of the structures of some giant viruses. As always, knowing the structure enhances the understanding of function greatly, in the case of viruses the mechanism of infection is a key problem. Rossmann has contributed many central insights in this area.Thus, this book is of interest both as an interesting personal story but also for research into viruses that repeatedly plague all living organisms on the planet, right now in the form of the corona virus pandemic.

I was highly flattered when I was asked by Mark Ladd and Rex Palmer if I would write the Foreword to this Fourth Edition of their book. "Ladd & Palmer" is such a well-known and classic book on the subject of crystal structure determination, one of the standards in the field: I did feel daunted by the prospect, and wondered if I could do justice to it. The determination of crystal structures by X-ray crystallography has come a long way since the 1912 discoveries of von Laue and the Braggs. In the intervening years great advances have been made, so that today it is almost taken for granted that crystal structures can be determined in which hundreds, if not thousands, of sepa rate atomic positions can be found with apparent ease. In the early years the struc tures of relatively simple materials, such as the alkali halides, were often argued over and even disputed, whereas today we routinely see published structures of most complex molecular crystals, including the structures of viruses and proteins.

Vasopressin is a hormone which has an increasingly important profile. Not only does it play a physiologically significant role in renal water regulation but it also has other renal actions and plays a role in overall cardiovascular control. Even more interesting is the recent growing interest in its potential effects on the brain, notably its influence on specific behaviours.This monograph about the polypeptide vasopressin covers all aspects relating to the production, control of release, and actions of this molecule within the body, including its roles as a hormone and as a central neurotransmitter. A consideration of the evolution of the molecule across the species and a brief historical perspective are also included. Clinical conditions associated with hypo- and hyper-production states are considered together with aspects of treatment, in addition to other clinical correlates./a
