Concanavalin A (Con A), a plant lectin, has become an object of extensive research not only for the biochemist, but also for the bi ologist, biophysicist, pathologist, immunologist and others. On April 19-20, 1974 a group of scholars from four continents met on the campus of the University of Oklahoma for an International Symposium on Con A. This volume contains all lectures presented by the invited speakers on this occasion, as well as the abstracts for all shorter technical papers which were presented. Further, the edi tors invited additional contributions from a few selected laboratories to cover the areas not covered in the symposium itself. This volume then reports the present status of research with Con A. In a sense it is encyclopedic and should be a useful reference tool to the worker in this field. The newcomer to this area will find that a careful study of this book will bring him up-to-date with the latest techniques, ap proaches and the "state of the art" in this specialized area of re search, as well as with traps and ensnarements in which he need not get entangled again. Starting at the molecular level and advancing from there to the organismic level as well as to a number of highly specialized areas, this volume presents the most complete survey of research findings with Con A available today. The editors wish to acknowledge the generous financial support provided by the University of Oklahoma through its President, Dr."

Food proteomics is one of the most dynamic and fast-developing areas in food science. The goal of this book is to be a reference guide on the principles and the current and future potential applications of proteomics in food science and technology. More specifically, the book will discuss recent developments and the expected trends of the near future in food proteomics. The book will be divided into two parts. The first part (7 chapters) will focus on the basic principles for proteomics, e.g., sample preparation, such as extraction and separation techniques, analytical instrumentation currently in use, and available databases for peptide and protein identification. The second part of the book (26 chapters) will focus on applications in foods. It will deal with quality issues related to post-mortem processes in animal foods and quality traits for all foods in general, as well as the identification of bioactive peptides and proteins, which are very important from the nutritional point of view. Furthermore, consumers are now extremely susceptible to food safety issues, and proteomics can provide reassurance with different safety aspects, such as food authenticity, detection of animal species in the food, and identification of food allergens. All of these issues will be covered in this book. It is also worth noting that both editors are internationally recognized experts in the field of food science, and both have edited numerous food science books and handbooks.

The knowledge of Th17 cells and other cell populations which secrete IL-17A, and/or IL-22 has expanded tremendously since the publication of the first edition "Th17 Cells: Role in Inflammation and Autoimmune Disease" in 2008. The present volume has been completely revised with the addition of new chapters on the IL-17 receptor family and signaling, and an in-depth review of IL-22 and innate lymphoid cells. The differentiation of na ve T cells into regulatory T cells and Th17 cells as well as the plasticity of Th17 cells is discussed. The role of IL-22 in cutaneous inflammation including psoriasis has been reviewed. In addition, the volume contains critical updates on autoimmunity, organ transplantation, tumor immunology and genetic mouse models for mechanistic studies. Lastly, the latest clinical progress in neutralizing antibodies to IL-17A, IL-17RA not only confirms the therapeutic promise foreseen in 2008, but also improves our knowledge of the pathogenesis of autoimmune diseases. In summary, this is a timely update and important review of the clinical and experimental aspects of IL-17, IL-22 and their producing cells.

The basic principle of electron crystallography is to calculate a 3D density map by combining the amplitudes obtained from electron diffraction patterns with the experimental phases calculated from images of two-dimensional crystals of membrane or soluble proteins. This technology is very well developed and has produced a number of atomic models of membrane proteins in a lipid environment. Focused on comprehensive experimental protocols, Electron Crystallography of Soluble and Membrane Proteins: Methods and Protocols covers the entire range of techniques used in electron crystallography, including protein sample preparation, 2D crystallization, and screening in negative stain over electron cryo-microscopy (cryo-EM) and data processing, as well as modeling of conformational changes. Additional chapters provide perspective on past, present, and future challenges as well as complementary methods. Written for the popular Methods in Molecular Biology (TM) series, the work contains the kind of detailed descriptions and implementation advice necessary to ensure successful results. Comprehensive and cutting-edge, Electron Crystallography of Soluble and Membrane Proteins: Methods and Protocols serves laboratories new to the methods as well as state-of-the-art facilities pursuing this exciting area of protein science.

The book is devoted to expanding current views on the phenomena of protein functionality in food systems. Protein functionalities in foods have been the object ofextensive research over the last thirty to forty years and significant progress has been made in understanding the mechanism and factors influencing the functionality of proteins. The functionality of proteins is one of the fastest developing fields in the studies of protein utilization in foods. Currently, a broad spectrum of data related to protein functionality in food systems has been collected, however, much more needs to be known. In this volume, the most important functional properties offood proteins are presented: Protein solubility, water holding capacity and fat binding, emulsifying, foaming, and gelling properties as affected by protein source, environmental factors (pH, temperature, ionic strength) and protein concentration; Relationships between protein conformation, physicochemical properties, and functional properties; Protein functional properties as influenced by various food processing conditions, particularly heat treatment, dehydration, freezing and storage when frozen, extraction and other processes; Effects ofprotein modification on the enhancementofprotein functionality; Utilization ofvarious proteins in improving functional properties in food systems. Those aspects of protein functionality are presented which the author believes to be interesting and most important for protein utilization in food systems. The book is recommended to students and food scientists engaged in food protein research and food industry research, and development scientists.

Research in the pharmaceutical industry today is in many respects quite different from what it used to be only fifteen years ago. There have been dramatic changes in approaches for identifying new chemical entities with a desired biological activity. While chemical modification of existing leads was the most important approach in the 1970s and 1980s, high-throughput screening and structure-based design are now major players among a multitude of methods used in drug discov ery. Quite often, companies favor one of these relatively new approaches over the other, e.g., screening over rational design, or vice versa, but we believe that an intelligent and concerted use of several or all methods currently available to drug discovery will be more successful in the medium term. What has changed most significantly in the past few years is the time available for identifying new chemical entities. Because of the high costs of drug discovery projects, pressure for maximum success in the shortest possible time is higher than ever. In addition, the multidisciplinary character of the field is much more pronounced today than it used to be. As a consequence, researchers and project managers in the pharmaceutical industry should have a solid knowledge of the more important methods available to drug discovery, because it is the rapidly and intelligently combined use of these which will determine the success or failure of preclinical projects.

The Proceedings of the Fourth International Metallothionein Meeting (MT-97) feature the latest research on metallothionein. The book covers a broad range of topics which provide important information for both basic and clinical investigators. The selected 94 articles in this book are written by the leading scientists in the field around the world. This is an increasingly important, multi-disciplinary area of study that has benefitted from recent advances in concepts and methodologies from other fields.

This work is concerned with a group of proteins which were originally consid ered to be an esoteric phenomenon but which have now been shown to play critical roles both in normal and stressed cells as well as being involved in a variety of human diseases. It is the purpose of this work to give a comprehen sive view of these proteins and their various aspects. After an introductory chapter providing an overview of these proteins, the work is divided into four main sections each of which deals with one important aspect of these proteins. Thus, the first section contains a series of chapters which describe individual stress proteins and their roles in particular biological phenomena. Evidently, the induction of these proteins by elevated tempera ture or other stresses is their defining feature and the second section of this book therefore considers the regulation of stress protein gene expression both by stressful stimuli such as elevated temperature or ischaemia and by non stressful stimuli such as cytokines.

PAS proteins control numerous physiological and developmental events, and span phylogeny from bacteria to man. Bacterial and plant PAS proteins act as sensors of environmental stimuli, including light, oxygen, and energy status. Not surprising, given these roles, there is intense investigation of the roles of bHLH-PAS proteins in issues of human health including: (1) cancer induction, (2) cancer growth and vascularity, (3) birth defects, including Down syndrome, (4) appetite control and obesity, (5) sleep rhythm disorders, and (6) mental health disorders such as social interactions and learning. PAS proteins encompass many fields of biology, and scientists who work in these fields (circadian rhythms, oxygen regulation, toxin metabolism, bacterial sensors, and development) are an audience, particularly those who actively work on PAS proteins and researchers interested in transcriptional control, signal transduction, and evolution.

This volume presents a review of the latest numerical techniques used to identify ligand binding and protein complexation sites. It should be noted that there are many other theoretical studies devoted to predicting the activity of specific proteins and that useful protein data can be found in numerous databases. The aim of advanced computational techniques is to identify the active sites in specific proteins and moreover to suggest a generalized mechanism by which such protein-ligand (or protein-protein) interactions can be effected. Developing such tools is not an easy task - it requires extensive expertise in the area of molecular biology as well as a firm grasp of numerical modeling methods. Thus, it is often viewed as a prime candidate for interdisciplinary research.

From the basic science to potential and approved clinical applications the most recent data in the rapidly growing field of bone morphogenetic proteins (BMPs) are summarized in this topical volume. Distinguished scientists present reviews on a range of scientific topics, including biochemistry, biology, molecular biology and preclinical animal studies on spinal fusion, cartilage repair, craniofacial and dental reconstruction using BMPs, as well as approved clinical applications in human bone non-unions.

This book provides a resource not only for experts in the field, but also for undergraduate students, newcomers and clinicians worldwide, given that the use of BMPs in orthopedic reconstruction has been already approved in Europe, Australia, Canada and the USA.

This book summarizes present knowledge of different mechanisms involved in the development of positive and negative consequences of cardiac adaptation. Particular attention is paid to the still underestimated adaptive cardiac responses during development, to adaptation to the frequently occurring pressure and volume overload as well as to cardiac changes, induced by enduring exercise and chronic hypoxia. "Cardiac Adaptations" will be of great value to cardiovascular investigators, who will find this book highly useful in their cardiovascular studies for finding solutions in diverse pathological conditions; it will also appeal to students, fellows, scientists, and clinicians interested in cardiovascular abnormalities."

The highly structured eucaryotic cell with its complex division of biochemical labour requires a distinct protein complement in each cellular structure and compartment. Nuclear coded and cytosolically synthesized polypeptides are specifically sorted to every corner of the cell in a post- or co-translational manner. The presence of separate genomes and protein translation machineries in plastids and mitochondria requires further coordination not only on the transcriptional, translational but also most likely on the protein import level. Numerous different protein transport systems have developed and coexist within plant cells to ensure the specific and selective composition of every sub-cellular compartment. This volume summarizes the current knowledge on protein trafficking in plant cells. Aside from the fundamental aspects in cell biology of how specific pre-protein sorting and translocation across biological membranes is achieved, a major focus is on transport, modification and deposition of plant storage proteins. The increasing use of plants as bioreactors to provide custom-designed proteins of different usage requires detailed understanding of these events. This text is directed not only at students and professionals in plant cell and molecular biology but also at those involved in horticulture and plant breeding. It is intended to serve as a text and guide for graduate-level courses on plant cell biology and as a valuable supplement to courses in plant physiology and development. Scientists in other disciplines who wish to learn more about protein translocation in plants will also find this text an up-to-date source of information and reference.

This book provides a premier resource on understanding the ribosome's essential nature and how it interacts with other proteins and nucleic acids to control protein synthesis. As one of the central foundations in our understanding of the biology at the molecular level, this topic appeals to a wide audience, from bench researcher to clinician. With the advent of atomic scale structures, methods to visualize and separate individual molecules, and the computational power to model the complex interactions of over a million atoms at once, our understanding of how gene expression is controlled at the level of protein translation is now deeply ensconced in the biophysical realm."

Super secondary structure(SSS) helps to understand the relationship between primary and tertiary structure of proteins. In Protein Supersecondary Structure: Methods and Protocols expert researchers in the field detail the usefulness of the study of super secondary structure in different areas of protein research. This is done through four main studies SSS representation, SSS prediction, SSS and protein folding, and other application of SSS concept to protein biology. Written in the highly successful Methods in Molecular Biology (TM) series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and key tips on troubleshooting and avoiding known pitfalls. Authoritative and practical, Protein Supersecondary Structure: Methods and Protocols highlight some of the major advances in the many fast-growing areas of supersecondary structure research.

The present book relates to the scientific records of a workshop held in Patras, Greece, in June 1989, under the auspices and with financial support of the European Economic Communities (Concerted Action EUROBIOMAT - Hemocompatibility - of the Medical Research Programme, Project: 11.1.212). This concerted action promotes the collaboration on science and technology on the particular field of hemocompatible biomaterials: exchange of experts, scholarships and scientific workshops within the EC-member countries and COST countries such as Sweden, Finland, Turkey, Switzerland. The first part of this monography refers to the oral presentations of the par ticipants. The second part gives the book its unique character: the scientific discussion on updated aspects of protein adsorption of synthetic polymers in contact with blood. This second part is subdivided into nine chapters where specific topics were discussed freely, open-minded and even controversially. This book intends to elucidate recurrent questions concerning the initial event when blood contacts artificial surfaces. Young investigators will consider this book to be appropriate to get familiar with the scientific background and the most relevant techniques and methods."

The book addresses the most recent developments in structural and functional proteomics underlying the recent contributions given in these areas by our laboratory to the instrumentations, the methods and the procedures as mutuated from the nanoscale sciences and technologies. These developments introduced in the last few years make now possible protein massive identification (mass spectrometry and biomolecular arrays down to nanoamounts) and protein structural characterization in solution and in crystals down to the atomic scale to an extent and to a degree so far unmatched. Emphasis is placed in the growth by nanobiofilm template of protein crystals of any type and size from millimeter to micron, leading in combination with microfocus synchrotron technology and atomic force microscopy to the definition of a new field called nanocrystallography. The few useful examples being shown, concerning yet structurally unsolved proteins, point this very promising approach nanotechnology-based in structural proteomics using highly focused X-rays. This has not to be confused with the important study of nanocrystals, both organic and inorganic, and novel diamond like nanocomposite materials and devices having 3D protein crystals as matrices to be equilibrated with nanoparticles/gold/silver to be utilized in the most diversified electronic applications here also summarized. vii Acknowledgments We are particularly grateful to Giuseppe Zanotti at the University of Padova for his fundamental collaboration during all the crystallographic studies.
