One ofthe major drivers in biological research is the establishment ofstructures and functions of the 50,000 or so proteins in our bodies. Each has a characteristic- dimensional structure, highly "ordered" yet "disordered"! This structure is essential for a protein's function and, significantly, it must be sustained in the competitive and complex environment of the living cell. It is now being recognised that when a cell loses control, proteins can se- assemble into more complex supermolecular structures such as the amyloid fibres and plaques associated with the pathogenesis of prion (CJD) or age-related (Alzheimer's) diseases. This is a pointer to the wider significance of the self-assembling properties of polypeptides. It has been long known that, in silk, polypeptides are assembled into- sheet structures which impart on the material its highly exploitable properties of flexibility combined with high tensile strength. But only now emerging is the recognition that peptides can Self-assemble into a wide variety of non-protein-like structures, including fibrils, fibres, tubules, sheets and monolayers. These are exciting observations and, more so, the potential for materials and medical exploitations is so wide ranging that over 80 scientists from Europe, USA, Japan and Israel. met 1-6 July 1999 in Crete, to discuss the wide-ranging implications of these novel developments. There was a spirit of excitement about the workshop indicative of an important new endeavor. The emerging perception is that of a new class of materials set to become commercially viable early in the 21st century.
Aminopeptidase N (APN)/CD13 and dipeptidylpeptidase IV (DPIV)/CD26 are proteolytic enzymes with ubiquitous occurrence in the body of animals and men. Their physiological roles depend on the respective location: in gut and kidney tubules degradation of smaller proteins and peptides serves in absorption of nutrients or reabsorption of amino acids from urine. In the CNS their important substrates are biologically active peptides (e.g. enkephalins). This book, however, has a strong focus on the role APN and DPIV play in the hematopoietic system, where again signal peptides and small proteins (cytokines) are among the most interesting substrates. Additionally, both the membrane bound peptidases play roles as partners in signal transduction of lymphocytes and monocytes, and inhibition of their enzymatic activity results in cell cycle arrest, inhibition of DNA synthesis and characteristic changes of cytokine secretion pattern of T cells. This knowledge more and more is used as the base of therapeutic strategies in the treatment of a variety of inflammatory and autoimmune diseases as well as of tumors of different origin. The editors themselves with their colleagues have contributed important results about APN and DPIV that are reviewed here, and additionally, most of the leading groups in this field from Europe, U.S., Australia and Japan have contributed reviews and latest, partially unpublished results of their work. Researchers of many fields of biosciences and medicine will find interesting reading in the book and new impulse for basic research as well as for clinical applications.
The aim of this book is to provide the researcher with important sample preparation strategies in a wide variety of analyte molecules, specimens, methods, and biological applications requiring mass spectrometric analysis as a detection end-point. In this volume we have compiled the contributions from several laboratories which are employing mass spectrometry for biological analysis. With the latest inventions and introduction of highly sophisticated mass spectrometry equipment sample preparation becomes an extremely important bottleneck of biomedical analysis. We have a goal of giving the reader several successful examples of sample preparation, development and optimization, leading to the success in analytical steps and proper conclusions made at the end of the day. This book is structured as a compilation of contributed chapters ranging from protocols to research articles and reviews. The main philosophy of this volume is that sample preparation methods have to be optimized and validated for every project, for every sample type and for every downstream analytical technique.
Recombinant DNA methods are powerful, revolutionary techniques for
at least two reasons.
Folding for the Synapse addresses the current view on how protein folding and misfolding, controlled by molecular chaperones, contribute to synapse function and dysfunction. Molecular chaperones have been studied in relation to de novo protein folding, but there is increasing awareness that chaperone function is required for the regulation of protein dynamics when functioning physiologically as an isolated moiety or part of a protein complex. This book will introduce both important concepts of folding machineries and give examples of the biological relevance of further chaperone functions.
This book represents the first serious attempt to explain the fundamental basis of ozonetherapy and is a relevant step towards achieving further progress. Ozone is now considered a real drug and, after reacting with body fluids, releases messengers and activates several mechanisms which are able to elicit multiple biological effects. The therapeutic window has been defined and, contrary to the dogma that ozone is toxic any way you deal with it', it has been shown that ozone toxicity can be tamed and even totally avoided. New powerful methodologies have been devised and astonishing clinical results in vascular and infectious diseases have already been achieved. An exciting novelty is the induction of an adaptive response that implies the unsuspected possibility of arresting cell degeneration due to endogenous chronic oxidative stress. However, further basic and controlled clinical studies need to be performed to fully exploit ozone's therapeutic potentials and to establish the real validity of this therapy. Authoritative scientists and clinicians should abandon their prejudice and consider the profound difference between endogenous oxidative stress and the new concept of ozonetherapeutic shock'. If this happens, we could soon have a simple and inexpensive tool to restore health in millions of patients. This book has been written in a plain scientific language and can be read by scientists and clinicians, as well as by patients keen on regaining a state of well being.
The environmental clean up industry has been estimated as having an annual turnover of $50 billion globally. With new regulations being written on addi tional chemicals that are just, now, becoming understood from a toxicological and environmental risk standpoint, this industry could expand even further. This is particularly true as more nations become industrialized. Typical conta minants that are of concern include agricultural byproducts, municipal wastes, industrial solvents, petroleum hydrocarbons, heavy metals, pesticides, radioac tive wastes, munitions, and other man made products. In order to treat and remediate these contaminants, practioners have several "tools" in the remediation "toolbox" including physical, chemical, and biological methods. One relatively new biological method that has been applied to address various environmental concerns is phytotechnologies. The method is defined as the use of vegetation to contain, sequester, remove, or degrade inorganic and organic contaminants in soils, sediments, surface waters, and groundwater. Although its roots were developed from other disciplines such as agronomy, agricultural engineering, chemical engineering, forestry, horticulture, hydroge ology, and microbiology, this set of technologies has grown substantially on its own in understanding of and application in the environmental clean up indus try around the world.
This fifth edition of the successful, long-selling classic has been completely revised and expanded, omitting some topics on obsolete DNA electrophoresis, but now with a completely new section on electrophoretic micro-methods and on-the-chip electrophoresis. The text is geared towards advanced students and professionals and contains extended background sections, protocols and a trouble-shooting section. It is now also backed by a supplementary website providing all the figures for teaching purposes, as well as a selection of animated figures tested in many workshops to explain the underlying principles of the different electrophoretic methods.
Praise for the Series:
Antibodies tagged with fuorescent markers have been used in histochemistry for over 50 years. Although early applications were focused on the detection of microbial antigens in tissues, the use of immunocytochemical methods now has spread to include the det- tion of a wide array of antigens including proteins, carbohydrates, and lipids from virtually any organism. Today, immunohistochemistry is widely used to identify, in situ, various components of cells and tissues in both normal and pathological conditions. The method gains its strength from the extremely sensitive interaction of a specifc antibody with its antigen. For some scientifc areas, books have been published on applications of immu- cytochemical techniques specifc to that area. What distinguished Immunocytochemical Methods and Protocols from earlier books when it was frst published was its broad appeal to investigators across all disciplines, including those in both research and clinical settings. The methods and protocols p- sented in the frst edition were designed to be general in their application; the accompa- ing "Notes" provided the reader with invaluable assistance in adapting or troubleshooting the protocols. These strengths continued to hold true for the second edition and again for the third edition. Since the publication of the frst edition, the application of immuno- tochemical techniques in the clinical laboratory has continued to rise and this third edition provides methods that are applicable to basic research as well as to the clinical laboratory.
Steroids is a thematic volume from the classic Academic Press series, Vitamins and Hormones. Gerald Litwack, the new editor of this prestigious serial, brings together leading contributors to the study of steroids. These structurally and functionally complex molecules are of interest to a broad cross-section of endocrinologist, cell biologists, and biochemists. Reviews include studies of structure, function, and regulation of steroid production and action. Thus, Vitamins and Hormones continues to publish cutting-edge reviews of interest to endocrinologists and biochemists. Others will increasingly turn to this continuing series for comprehensive reviews by leading researchers in this and related disciplines.

The critically acclaimed laboratory standard, Methods in Enzymology, is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. The series contains much material still relevant today - truly an essential publication for researchers in all fields of life sciences.
International concern in scientific, industrial, and governmental communities over traces of xenobiotics in foods and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are inte grated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamina tion and toxicology. This series is reserved exclusively for the diversified litera ture on ''toxic'' chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tre mendous efforts worldwide have been mobilized to evaluate the nature, pres ence, magnitude, fate, and toxicology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest impor tant world literature produced by these emerging areas of science together with documentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individuals need the background provided by detailed reviews and the assurance that the latest infor mation is made available to them, all with minimal literature searching."

Nuclear receptors are ligand activated transcription factors that control numerous biological functions. Consequently, altering activity of these receptors is proposed, and indeed documented, to affect many physiological and pathological conditions in experimental animals and humans. Thus, nuclear receptors have become a major target in the effort to treat numerous diseases.This book will shed light on and emphasize intricate processes involved in designing as well as discovering physiological and pharmacological modulators of these important proteins. World-renowned scientists will share with the reader their professional expertise and extensive experience acquired through decades working with nuclear receptors. Chapters address the various means and consequences of modulating nuclear receptor activity will be presented and discussed. These modulators cover a wide span of moieties ranging from synthetic chemicals to natural products. In addition, the classification of these chemicals ranges from pan agonists to selective agonists and inverse agonists to antagonists. They also include proteolytic means to obliterate the receptor in the event that modulating its activity through canonical pharmacological agents becomes less effective and/or less desirable due to anticipated or experienced toxicities. Modulation of receptor activity may also take place in the absence of a ligand or through manipulating the structure of the receptor itself by controlling posttranslational events.
Protein Folding Kinetics - Biophysical Methods (2nd Edition) gives a deep insight into the principles and concepts of the kinetic and structural resolution of fast chemical and biophysical reactions of proteins with emphasis on protein-folding reactions. The study of fast protein-folding reactions and the understanding of the folding paradox have significantly advanced due to the recent development of new biophysical methods which allow not only kinetic resolution in the sub-millisecond time scale but also structural resolution with unprecedented precision. Pathways and structures of early and late folding events and the transition state structures of fast- and ultrafast-folding proteins can now be studied in far more detail. Important techniques include biophysical, chemical, molecular biological and mathematical methods, in particular protein engineering, Phi-value analysis, time-resolved circular dichroism, optical triggers and pulsed infrared LASER methods, pressure and temperature jump, ultrafast mixing, stopped flow and quenched flow, dielectric relaxation and electric-field-jump, acoustic relaxation, fluorescence- and isotope-labeling, H/D exchange methods, NMR line broadening and stopped-flow NMR, transition state theory, solutions of rate equations, and evolutionary computer programming. Protein Folding Kinetics - Biophysical Methods is written for students and researchers in biochemistry, biophysics, and related fields. Special features in the second edition: -Includes detailed information and 12 color figures on the high resolution of folding transition states. -Discusses structural determinants of the rate of protein folding on a timescale from microseconds to seconds. -Provides information on self-evolving computer programs for protein-folding simulations and protein-structure predictions.
Parkinson s Disease (PD) is a progressive neurodegenerative disease with a prevalence of 0.1% of the global population, and 5-10% patients are under 40 years of age. Several text books have been published on various aspects of PD to date, including research and clinical aspects. However these do not emphasize the inflammatory pathways and pathways of neurodegeneration in PD. "Inflammation in Parkinson s Disease" brings advances in research together with current literature and evidence.This concise volume covers the fundamentals of neuroimmunology and inflammatory models, the interactions between pathways of neurodegeneration and follows the concept of research work undertaken from basic science to clinical trials. Researchers, clinicians, and students interested in Parkinson's Disease are provided with a comprehensive view of translational research methods and an insight needed for developing future therapies aimed at disease modulation."
Blurb for Volume 1
Protein kinase CK2 (formerly casein kinase II or 2) is known to play a critical role in the control of cell growth and cell death and is thus intimately involved in the development of cancer. More specifically, CK2 has been found to be elevated in all cancers examined. While CK2 levels are known to be high in proliferating normal cells, CK2 has also been found to be a potent suppressor of apoptosis and is a link to the cancer cell phenotype, which is characterized by deregulation of both cell proliferation and cell death. Indeed, it would appear that CK2 impacts many of the hallmarks of cancer and it has now gained considerable attention as a potential target for cancer therapy. Protein Kinase CK2 and Cellular Function in Normal and Disease States increases knowledge of the role of CK2 in the development of cellular dysfunction and emphasizes that this protein may serve as a target of drug development for improved cancer therapy. In addition, it is a handy tool that provides cancer researchers, graduate students, and all scientists involved in CK2 research with one main source for the latest advances in CK2 research.
This detailed volume explores advances in vector design, DNA delivery, cell cultivation, host cell engineering, and bioprocess optimization within the study of recombinant protein expression in mammalian cells. The majority of the protocols employ either Chinese hamster ovary cells (CHO) or human embryonic kidney 293 cells (HEK293), the workhorses of the field, as the production host; however, the methods can be adapted to other mammalian hosts under the appropriate cell-specific conditions. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and convenient, Recombinant Protein Expression in Mammalian Cells: Methods and Protocols aims to aid researchers in building on our knowledge of protein structure and function and to speed the discovery of new therapeutic proteins.
Forensic professionals, particularly medical examiners-often working through heavy caseloads-require quick and easy access to reliable sources of information to help interpret toxicology results. While several in-depth resources are available, they are often large, cumbersome, and contain more information than is often needed. The Handbook of Forensic Toxicology for Medical Examiners is a concise handbook referencing the most common toxic substances and their reported non-toxic, toxic, and lethal concentrations, making it an ideal text for quick reference in the lab or autopsy room. Features of the Second Edition: Explains the principles of postmortem toxicology and the factors which must be considered Provides tables of toxicologic data for over 200 commonly encountered substances, including drugs of abuse, poisons, prescription drugs, and over-the-counter medications Includes discussion and description of the novel psychoactive drugs-including synthetic opioids, cannabinoids, stimulants and hallucinogens Supplemental appendices provide additional information regarding specimen types and selection, testing methodologies, normal laboratory values, and conversion charts The busy forensic professional needs a concise handbook that provides critical information quickly and accurately. This heavily referenced text offers an easy-to-use format allowing for rapid access for both routine daily use and preparation for courtroom testimony.
This volume describes high-throughput approaches to a series of robust, established methodologies in molecular genetic studies of population samples. Such developments have been essential not only to linkage and association studies of single-gene and complex traits in humans, animals and plants, but also to the characterisation of clone banks, for example in mapping of genomes. Chapters have been written by developers or highly experienced end-users concerned with a diverse array of biological applications. The book should appeal to any researcher for whom costs and throughput in their genetics laboratory have become an issue.
The synthesis of proteins from 20 or so constituent amino acids according to a strictly defined code with an accuracy of better than 1 in 10,000 at most loca tions is arguably the most complex task performed by cells. Protein Synthesis collects together methods and protocols covering a range of different approaches towards understanding how the cellular machinery accomplishes this task and how these ftinctions might be harnessed by the biotechnology industry to generate novel and useful proteins. The era in which the components of the translational machinery were being catalogued is over. This volume gathers together protocols that focus on preserving and describing the dynamic function as closely as possible. The need to understand exactly how ribosomes are positioned on messages or where tRNA molecules, translation factors, or control proteins are bound, has been appreciated by many of the authors. Several chapters that explore the fidelity and processivity of translation reflect this belief. Moreover, the fundamental importance of rRNA at the heart of the ribosome is a strong theme in a number of the protocols. These articles include in vitro and in vivo systems from bacterial, fungal, plant, and animal systems. Overall, Protein Synthesis might be characterized by the novelty of the approaches employed to illuminate the inner workings of the protein synthetic machinery as well as by the inventiveness of the attempts to harness these reactions for biotechnological applications."
Large areas of crops are now grown under water-stressed conditions on non-irrigated and under limited irrigation in semi-arid and arid regions. In the future, this area of water-stressed crops will increase as a result of increasing competition from other water users, declining ground water levels, and the bringing into production of fragile lands that have low water-holding capacity, such as sandy desert soil. Consequently, strategies and practices to increase total yields and efficient water use must be improved. Following the introductory material and keynotes, this book is divided into four parts. Part I covers soil water management, Part II deals with model approaches to evaluate the soil-water-atmosphere interactions, Part III treats water saving techniques through soil conditioning, and Part IV discusses case studies of water management systems. "Water Saving Techniques for Plant Growth" thus represents a general account of interest and activities of the various scientific disciplines which are concerned in deseert encroachment as part of global change. |
