As genomics gives way to proteomics as the focus of scientific imagination in the biological sciences, more emphasis will be placed on the technology and interpretation of protein engineering experiments. Protein engineers will become increasingly sophisticated in the questions that they pose and demanding of the tools available to change protein structure. The optimal way to introduce non-coded amino acids for mechanistic studies, or site-specific reporter atoms for spectroscopic structural biology, is by protein semisynthesis. In Protein Engineering by Semisynthesis, the leading practitioners of the method cover their individual protein of expertise forming a comprehensive illustration of the various methods developed. By covering the most recent philosophical and methodological approaches and developments of semisynthesis and peptide synthesis to date, this book provides further understanding of the principles of protein structure-function relationships gained from semisynthetic analog in addition to providing a comprehensive and comprehensible laboratory guide. This book focuses on recent developments which synergistically combine chemical and molecular biological techniques that have made semisynthetic manipulations much easier to undertake. Features

One day, in a moment of weakness, I fell prey to the temptation to organize and edit this volume on the mechanism of insulin action. The major reason for attempting to resist, of course, is the amazing speed at which advances are being made in this field. The usefulness of books such as this is often quickly compromised by new findings obtained during and just after publication. Happily for the contributors to this volume and myself, this unfortunate fate does not appear to be in store for us. New and important findings will undoubtedly continue to flow in this field during the next few years, but I believe this will increase rather than decrease the usefulness of this volume. As a matter of fact, as we go to press, I am delighted both that I was tempted and that I failed to resist. There are two basic reasons for my enthusiasm about this book, and they both relate to this issue of timeliness. First, each of the contributors has had an opportunity to update the scientific content of the various chapters only a few months before actual publication of this volume. The material presented in this volume is, at publication, contemporary with the current original literature. This volume thus provides an ex cellent framework for assessing new discoveries in this field for some time to come.
Biochemical Actions of Hormones, Volume II is a 12-chapter text that surveys the significant developments toward understanding the primary effects of hormones in cellular receptors at the molecular level. This book starts with an overview of the genetic regulation by hormones and the role of cyclic adenosine monophosphate in hormonal response. These topics are followed by discussions on the hormone-dependent molecular mechanisms, which appear to participate in the regulation of cell proliferation and differentiation in this model system, as well as how multiple hormonal signals may serve to integrate a large number of complex regulatory mechanisms. A chapter deals with the comparative aspects of the physiology and biochemistry of insulin, with an emphasis on the molecular mode of action of insulin on metabolic processes. The remaining chapters deal with the physiology, mechanism of action, and biological effects of various hormones, including catecholamines, glucocorticoids, estrogens, progestins, gonadotropins, prolactin, adrenocorticotropic hormone, 25-hydroxycholecalciferol, and insect hormones. Endocrinologists will find this book invaluable.

Since insulin became available for the treatment of diabetes in 1922 a number of major advances have been made, which include the modification of insulin to vary its timing of action, its purification, and latterly, the production of human insulin. Human insulin in quantities sufficiently large for therapy has been made available by two techniques developed in parallel during the late 1970s. These involve either (i) formulation in E. coli bacteria suitably encoded by DNA recombinant methods of the A- and B-chains of human insulin followed by a chain combination reaction ('biosynthetic' human insulin) or (ii) enzymatic conversion (transpeptidation) of porcine insulin brought to react with a threonine ester by porcine trypsin in a mixture of water and organic solvents, yielding human insulin ('semi-synthetic' human insulin). This book includes the first clinical-pharmacological studies of each of the highly purified 'semi-synthetic' human insulin preparations: Actrapid ® HM; Monotard® HM; Protaphane® HM; Actraphane® HM; and Ultratard® HM (Novo Industri A/S, Copenhagen). The preliminary studies established their safety and efficacy relative to their porcine and bovine counterparts emphasising the relevance of species and formulation on the pharmacokinetics and biological responses to insulin. Additional investigations with human insulin demonstrated the influence of insulin concentration, site of administration, the addition of aprotinin to insulin and the mixing of 'short-' and 'intermediate-acting' formulations on insulin 'bioavailability'. Examination of the 'within' and 'between' subject day-to-day variation in absorption and the effect of subcutaneous insulin also demonstrates the dominating influence of insulin responsiveness.

On August 25,1976 Prof. Dr. med. JEAN NORDMANN, Emeritus Professor of Strasbourg University, will celebrate his 80th anniversary. The task of paying tribute to Professor NORDMANN's many services to ophthalmology in a way worthy of the occasion is so difficult that we decided to concentrate on the focal point of his life's work. In this issue scientists engaged in lens research from allover the world offer reports of their latest findings together with their best wishes and felicitations as a birthday gift to the Nestor of lens research. They thereby express their gratitude to Professor NORDMANN, who, with the lifelong in defatigable enthusiasm of a scientist, has most successfully persued the prob lems of lens metabolism. It is our sincerest hope that we may look forward to many more years in which to take advantage of Professor NORDMANN's superior knowledge. Among the contributions to this festive donation we miss the works of some authors who have always held Professor NORDMANN's special inter est. The editor has received several letters of longstanding friends who would have liked to submit a manuscript but had been unable to meet the deadline: Professor NORDMANN may rest assured that they, too, belong to the great number of congratulators from our field of research. We have been able to make this dedication thanks to Professor HENKES who readily agreed to publish our contributions in Documenta Ophthal mologica. Dr. Junk publishers have done their utmost to ensure prompt publication.

This significant new publication provides a summary and overview of the most recent scientific advances in diabetes research, and highlights the role of these developments in advancing clinical practice. Diabetes is one of the major causes of morbidity and mortality in the developed world, and its prevalence elsewhere is on the increase. It affects in excess of 100 million people worldwide. Recent scientific advances have clarified our understanding of the causes and consequences of this devastating disease. These scientific developments are playing an increasingly important role in clinical practice and could well lead the way to the prevention of complications and even a cure for the disease. An international and authoritative team of authors draws together this knowledge and the most recent developments to provide an up to date account which will benefit researchers and clinicians.
