The Chemical Biology of Thrombin

by Roger L. Lundblad

This book is a comprehensive review of thrombin, especially as regulatory protease. The ready availability of highly purified thrombin has stimulated rapid advances in the cell biology of this important macromolecule. The text focuses on research findings from the discovery of thrombin by Andrew Buchanan in 1842 to the present. A substantial amount of this work was conducted by the author and his colleagues. His work on the purification of thrombin was seminal to much subsequent work on thrombin. This volume provides a framework for future studies now made possible by the discovery of the importance of exosites in the physiology of thrombin function. The current work describes the process of the development of an oral inhibitor of thrombin used in the prevention of thrombosis. Key Features Reviews the history of Thrombin (Fibrin Ferment) Documents the relation of protein engineering and chemical modification in the study of thrombin Summarizes the interaction of thrombin with fibrinogen and fibrin Outlines the role of exosites in thrombin function Describes the development of an oral inhibitor for thrombin

Chemical Carcinogenesis (Nato Science Series A: #52)

by Claudio Nicolini

During October 18-30, 1981, the second course of the International School of Pure and Applied Biostructure, a NATO Advanced Study Institute, was held at the Ettore Majorana Center for Scientific Culture in Erice, Italy, co-sponsored by the International Union Against Cancer, the Italian League Against Cancer, the Italian Ministry of Public Education, the Italian Ministry of Scientific and Technological Research, the North Atlantic Treaty Organization, the Italian National Research Council, the Sicilian Regional Government and two pharmaceutical Companies (Zambeletti and Farmitalia). The subject of the course was "Chemical Carcino­ genesis" with participants selected world-wide from 18 different countries. It is now eminently clear that.the bulk of human cancers are related to one of several types of environmental exposure. Of the environmental hazards, chemicals are among the best characterized carcinogens. However, how chemicals induce cancer is still poorly understood. Because of the magnitude of the problem and the ob­ vious need for a much more critical scientific analysis of the process by which cancer is induced (carcinogenesis), it was highly desirable to expose a greater number of scientists with varying background to some of the latest thinking in chemical carcino­ genesis. The course had this as its major objective and the re­ sulting book does reflect it.

Chemical Carcinogenesis (Current Cancer Research)

by Trevor M. M. Penning

This volume will provide a contemporary account of advances in chemical carcinogenesis. It will promote the view that it is chemical alteration of the DNA that is a route cause of many cancers. The multi-stage model of chemical carcinogenesis, exposure to major classes of human carcinogens and their mode-of-action will be a focal point. The balance between metabolic activation to form biological reactive intermediates and their detoxification, ensuing DNA-lesions and their repair will be profiled. It will describe the chemical changes that occur in DNA that result from endogenous insults including epigenetic changes that lead to gene silencing. It will describe major mechanisms of mutagenesis, affects on tumor suppressor genes and proto-oncogenes, and how cell-cycle check points can be by-passed by the "stealth-like" properties of chemical carcinogens. Environmental agents that can promote tumor formation will be discussed. The monograph will have wide appeal as a knowledge base for graduate students, post-doctoral fellows and faculty interested in this aspect of cancer causation and research.

Chemical Carcinogenesis 2: Modulating Factors

by Amedeo Columbano Francesco Feo Rosa Pascale Paolo Pani

"chemical carcinogenesis" is the general title of the series of international meetings which are held, biannually, in sardinia (Italy) since 1981. Despite the generality of the title, the main effort of the scientific Committee has been to pursue a coherent line around one of the most distinguishing features of carcinogenesis: the "multifasic" development of the process. Given that many chemical compounds are known to cause "experimental cancer", many questions still remain unresolved or are given too simplistic answers. The very first question concerning the interaction between the chemical carcinogen and the molecular target in the cell is a debatable one despite the overwhelming literature in this field. It is certain that chemical carcinogens are toxic to cells and cause DNA damage: however it is still an open question as to how to relate these changes to the different stages of carcinogenesis including initiation. We have not to forget that 1/3 to 2/3 of the average life time of a given species elapses between the experimental administration of the carcinogen and the appearance of "cancer". The experimental manipulation of carcinogenesis through the use of "adequate biological models" has not simplified the problems about cancer, but it has led us to face the complexity of otherwise elementary biological properties, cell proliferation and differentiation. The understanding of this biological complexity is not just theoretical, but it may give us those adequate conceptual tools to approach "cancer" also from a medical point of view.

Chemical Carcinogenesis and Mutagenesis I (Handbook of Experimental Pharmacology #94 / 1)

I have been privileged to witness and participate in the great growth of knowledge on chemical carcinogenesis and mutagenesis since 1939 when I entered graduate school in biochemistry at the University of Wisconsin­ Madison. I immediately started to work with the carcinogenic aminoazo dyes un­ der the direction of Professor CARL BAUMANN. In 1942 I joined a fellow graduate student, ELIZABE1H CAVERT, in marriage and we soon commenced a joyous part­ nership in research on chemical carcinogenesis at the McArdle Laboratory for Cancer Research in the University of Wisconsin Medical School in Madison. This collaboration lasted 45 years. I am very grateful that this volume is dedi­ cated to the memory of Elizabeth. The important and varied topics that are reviewed here attest to the continued growth of the fields of chemical car­ cinogenesis and mutagenesis, including their recent and fruitful union with viral oncology. I feel very optimistic about the application of knowledge in these fields to the eventual solution of numerous problems, including the detection and estimation of the risks to humans of environmental chemical carcinogens and re­ lated factors.

Chemical Carcinogens: Some Guidelines for Handling and Disposal in the Laboratory

by Marcel Castegnaro Eric B. Sansone

"The chemical laboratory is actually not a dangerous place to work in, but it demands a reasonable prudence on the part of the experimenters and instructers, to keep it a safe place. Emphasis must be positive, indicating the proper, correct and safe procedure to be followed in all laboratory operations or when confron­ ted with an emergency situation. Too heavy stress upon the horrors associated with laboratory accidents or graphic descriptions of gory injuries or nasty fires should be avoided. Frightened, timid students are more likely to have accidents than the confident laboratory man who works with due regard to safety. " This statement, written by 1. R. Young (1) in 1971, in The Journal of Chemical Education, applies not only to students working in the chemical laboratory but can be extended to all scientists and technicians working with hazardous products, and in particular with chemical carcinogens. The hazards of handling toxic or dangerous chem­ icals have been well documented. Besides safety notices and articles in the scientific literature, a large number of books have been dedicated to this subject, among which can be cited Safety and Accident Prevention in Chemical Operations (2), Handbook of Laboratory Safety (3), Hazards in the Chemical Laboratory (4), 1 Handbook of Reactive Chemical Hazards (5), Safety in Working with Chemicals (6) and Prudent Practices for Handling Hazardous Chemicals in Laboratories (7).

Chemical Constituents of Bryophytes: Bio- and Chemical Diversity, Biological Activity, and Chemosystematics (Progress in the Chemistry of Organic Natural Products #95)

by Yoshinori Asakawa Agnieszka Ludwiczuk Fumihiro Nagashima

For some 50 years, Professor Asakawa and his group have focused their research on the chemical constituents of bryophytes and have found that these plants contain large numbers of secondary metabolites, such as terpenoids, acetogenins, and aromatic compounds representative of many new skeletons, which exhibit interesting biological activities. Individual terpenoids, when found as constituents of both a bryophyte and a higher plant, tend to occur in different enantiomeric forms. Professor Asakawa has covered the literature on bryophytes in two earlier volumes of Progress in the Chemistry of Organic Natural Products, namely, Volumes 42 (1982) and 65 (1995). Since the publication of the latter volume, a great deal of new information has appeared on bryophytes. One example is that known sex pheromones of algae have been discovered in two liverworts, indicating that some members of the latter taxonomic group might originate from brown algae. From information provided in this volume, it is suggested that two orders of the Marchantiophyta should be combined.

Chemical Exchange Saturation Transfer Imaging: Advances and Applications

by Michael T. McMahon Assaf A. Gilad Jeff W. M. Bulte Peter C. M. van Zijl

This is the first textbook dedicated to CEST imaging and covers the fundamental principles of saturation transfer, key features of CEST agents that enable the production of imaging contrast, and practical aspects of preparing image-acquisition and post-processing schemes suited for in vivo applications. CEST is a powerful MRI contrast mechanism with unique features, and the rapid expansion it has seen over the past 15 years since its original discovery in 2000 has created a need for a graduate-level handbook describing all aspects of pre-clinical, translational, and clinical CEST imaging. The book provides an illustrated historical perspective by leaders at the five key sites who developed CEST imaging, from the initial saturation transfer NMR experiments performed in the 1960s in Stockholm, Sweden, described by Sture Forsén, to the work on integrating the basic principles of CEST into imaging by Robert Balaban, Dean Sherry, Silvio Aime, and Peter van Zijl in the United States and Italy. The editors, Drs. Michael T. McMahon, Assaf A. Gilad, Jeff W. M. Bulte, and Peter C. M. van Zijl, have been pioneers developing this field at the Johns Hopkins University School of Medicine and the Kennedy Krieger Institute including contributions to Nature Medicine, Nature Biotechnology, Nature Materials, and the Proceedings of the National Academy of Sciences. As recognition for their initial development of the field, Drs. van Zijl and Balaban were awarded the Laukien Prize in April 2016, established in 1999 to honor the memory of Professor Gunther Laukien, a co-founder of Bruker Biospin GmbH.

For example, the generation of their protein targets and methods for measuring their interactions is covered. Written in the highly successful Methods in Molecular Biology™ series format, methodology 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. Thorough and up to date, Chemical Genomics and Proteomics: Reviews and Protocols aims to provide inspiration to those who wish to use chemical genomics and proteomics in their work and develop this young field into full maturity through the incorporation of the new biological and chemical technologies beginning to emerge here.

Chemical Induction of Cancer: Modulation and Combination Effects an Inventory of the Many Factors which Influence Carcinogenesis

by Joseph C. Arcos Mary F. Argus Yin-Tak Woo

In the approach to the analysis of disease, including, of course, cancer, two major thrusts may be distinguished. These may be referred to, in shorthand, as agents and processes: the causative agents (chemical, microbial, physical, environmental, and psychosocial) and the organismic processes, initiated and furthered by the agents, culminating in observable pathology (at the macromolecular, cytological, histological, organ function, locomotor, and behavioral levels). The past 25 years, since the appearance of the first volume of the predecessor series (1) authored by the Editors of this present volume, have seen an impressive number of studies on chemicals (and other agents) as etiologic factors in the induction of cancer. The major emphasis has been on the discovery of many chemical carcinogens of widely different structures, their metabolism by various tissues and cells, and, in turn, their molecular-biochemical effects on the cells. This rapidly expanded body of information, as effectively covered in the predecessor volumes, is an excellent entree to the second half of the overall problem of chemical carcinogenesis, the processes. The active agents trigger a large array of molecular-biochemical alterations to which the target cells, target tissues, and target organisms respond in many select and common ways. This second major aspect of the induction of cancer by chemicals (and by other agents)- the sequence of cellular and tissue changes clearly relevant to cancer-remains the challenge for the future.

Chemical, Microbiological, Health and Comfort Aspects of Indoor Air Quality - State of the Art in SBS (Eurocourses: Chemical and Environmental Science #4)

by Helmut Knöppel Peder Wolkoff

Interest in indoor air quality (IAQ) is growing at public, political and scientific levels. Complaints about poor IAQ, associated with acute symptoms such as mucous irritation, headaches and bad odor occur frequently, particularly in the office environment, where typical patterns of symptoms often occur, leading to the coining of the term `Sick Building Syndrome'. In the present book, internationally known experts address the following issues: the dynamics of the indoor environment and strategies for indoor measurement chemical and microbiological pollution, important species, sources and detection methods effects of indoor pollution, in particular sensory irritation, including odor airway, eye and skin irritation by organic indoor pollutants and their assessment immune effects, including allergic sensitization chemical hyper-responsiveness controlled human reactions to organic pollutants building investigation: approaches and results source characterization and control criteria, norms and techniques in indoor air pollution, and regulatory aspects. The complex, multifactorial nature of sick building syndrome requires multidisciplinary collaboration from very diverse fields. It is evident that communication between researchers coming from very different areas, all speaking their own language, is a difficult task. This book, presenting as it does the state of the art on sick buildings and how to cure them, is a sound foundation on which to build for the future.

Chemical Mixtures and Combined Chemical and Nonchemical Stressors: Exposure, Toxicity, Analysis, and Risk

by Cynthia V. Rider Jane Ellen Simmons

In this book, both basic and advanced concepts are discussed for considering mixtures from initial exposure characterization through evaluation of risk associated with combined exposures. This book will provide an introduction to key issues and multiple options for evaluating both the toxicity of mixtures as well as the risk associated with exposure to mixtures. Additionally, promising tools adapted from other disciplines will be discussed in the context of mixtures toxicology and risk assessment. Finally, the discussion will move beyond chemical mixtures to address incorporating non-chemical stressors into toxicity studies and cumulative risk assessments. Although exposure to multiple chemical and non-chemical stressors is the rule, not the exception, consideration of mixtures in toxicology and risk assessment continues to be a significant challenge. This book will be an essential resource for researchers and professionals in the fields of toxicology, epidemiology, exposure science, risk assessment, and statistics.
