The last 15 years have brought an understanding of growth and differentiation at the molecular level, expanding our knowledge of the origin and progression of cancer. Early breakthroughs defining growth control pathways came via studies of oncogenes, mutated signaling molecules that have lost the capacity to tum off their proliferative signal. Oncogenes with diverse growth-promoting activities have been discovered, covering the gamut from cell surface to nuclear signaling. Sequencing of these oncogenes revealed that they were mutated forms of captured cellular genes and displayed tyrosine kinase activity. The epidermal growth factor (EGF) receptor was the first of 40-50 transmembrane tyrosine kinase receptors to be cloned and sequenced. Beyond cell proliferation, activation of EGF receptor by its specific ligands controls important physiological processes, such as cell differentiation, apoptosis, cell migration, and cell shape. Activation of autocrine growth loops, consisting in solid human tumors of upregulated expression of EGFR together with increased production of ligands suggested its crucial role in autonomous tumor growth.

Many of the reactions and compounds involved in metabolism are almost iden tical in the different groups of living organisms. They are known as primary me tabolic reactions and primary metabolic products. In addition, however, a wide variety of biochemical pathways are characteristic of only a few species of organ isms, of single "chemical races", or even of a certain stage of differentiation of specialized cells. Such pathways are collectively referred to as "secondary metab olism", and the compounds formed are called "secondary products". Secondary products are frequently revealed by their color, smell, or taste. They are responsi ble for the flavor of most foodstuffs and beverages and for the color and fragrance of flowers and fruits. Many of them are part of the materia medica, e. g. , alka loids, cardiac glycosides, antibiotics, or compounds acting as hormones. Others are used in the industry, e. g. , rubber, tannins, and cellulose. This book treats the organization and significance of biosynthesis, storage, transformation, and degradation of the most important groups of secondary pro ducts in microorgimisms, plants, arid animals. It shows that the formation of sec ondary products is a common characteristic of specialized cells brought about by the action of special enzymes encoded by specific genetic material.

Collagen is a fascinating protein not only because of its ubiquitous occurrence in multicellular animals, but also because of its unique chemi cal structure. As the predominant constituent in bone, cartilage, skin, tendon, and tooth, it is not surprising that collagen is of interest to anatomists, biochemists, biomedical engineers, cell biologists, dermatolo gists, dental surgeons, leather chemists, orthopedic surgeons, physiologists, physicians, zoologists, and a host of others. This book was planned to provide an up-to-date comprehensive survey of all aspects of biochemistry of collagen. The recent discovery of genetically distinct collagens with tissue specificity has opened a new era in collagen biochemistry, and Karl Piez discusses this in the opening chapter on primary structure. In the next chapter, Ramachandran and Rama krishnan deal with the molecular structure of collagen, placing special emphasis on the conformational aspects of its polypeptide chains. Follow ing the consideration of primary and secondary structure of collagen, the three-dimensional arrangement of collagen molecules in the fibrils is covered by Miller in Chapter 3. Collagen is generally in the insoluble state in the living organism due to the cross-linking of individual molecules, and Tanzer describes the various aspects of this cross-linkage in Chapter 4. The biosynthesis of collagen is discussed in depth by Prockop and his colleagues."

How do firms jointly develop open information infrastructures? To answer this question, this book draws on the results of a longitudinal research project covering the development of the pharmaceutical distribution industry in China from 2004 to 2012, focusing on the emergence and subsequent evolution of industry-wide information infrastructures. How do firms delimit areas of proprietary innovation in open innovation projects? How do firms coordinate, initiate, negotiate and implement the development of innovative infrastructures? How do processes and practices within firms enable and constrain such collective efforts? - This book provides answers to these questions and draws conclusions regarding the challenges and new capabilities that firms will need in a world in which participation in the building of open information infrastructures becomes a necessary task for commercial organizations.

Diversity within and among living organisms is both a biological impera tive and a biological conundrum. Phenotypic and genotypic diversity is the critical currency ofecological interactions and the evolution of life. Thus, it is not unexpected to find vast phytochemical diversity among plants. However, among the most compelling questions which arise among those interested in ecological phytochemistry is the extent, nature, and reasons for the diversity of chemieals in plants. The idea that natural products (secondary metabolites) are accidents of metabolism and have no biological function is an old one which has resurfaced recently under a new term "redundancy. " Redundancy in the broader sense can be viewed as duplication of effort. The co-occurrence of several classes of phytochemieals in a given plant may be redundancy. Is there unnecessary duplication of chemical defense systems and ifso, why? What selective forces have produced this result? On the other hand, why does the same compound often have multiple functions? At a symposium of the Phytochemical Society of North America held in August 1995, in Sault Ste. Marie, Ontario, Canada, the topic "Phytochernical Redundancy in Ecological Interactions" was discussed. The chapters in this volume are based on that symposium. They both stimulate thought and provide some working hypotheses for future research. It is being increasingly recognized that functional diversity and multiplicity of function of natural products is the norm rather than the exception.

Hydroxybenzophenones are most useful synthetic intermediates in the chemical industry, for example in pharmaceuticals, dyes, fragrances, agrochemicals, explosives and plastics. In this handbook, the diverse methods of obtaining over 1900 hydroxybenzophenones are described, and their physico-chemical properties and spectroscopic data references are indicated. Hence, ketones are classified methodically. They are thus easily accessible from three tables; the molecular formula index, the chemical abstracts registry numbers, and the usual names index. This work will prove to be a valuable tool for laboratory work and research and development departments. It is set to become the reference on hydroxybenzophenones. This handbook is particularly intended for engineers in chemical synthesis and academic as well as industrial researchers from various branches of chemistry.

Bioassay Methods in Natural Product Research and Drug Development contains the proceedings from the Phytochemical Society of Europe's very successful symposium on this topic, held August 24-27, 1997 in Uppsala, Sweden. In this volume, leading academic and industrial scientists discuss novel methods for assaying natural products to find new structure-activity relationships. Of key importance in this process is the availability and reliability of specific bioassay methods, but chapters also discuss chemical and biological diversity and how to dereplicate natural product extracts to increase efficiency in lead discovery. Anti-tumor, HIV-inhibitory, antiprotozoal, anti-infective and immunomodulatory natural products are discussed. Various industrial projects are presented for the first time. This volume bridges the gap between academic and industrial research and scientists, and should be required reading in drug companies and faculties of pharmacy, as well as serving scientists in pharmacognosy, pharmacology, phytochemistry, natural products and drug discovery.

Piper is an economically and ecologically important genus of plant that includes a fascinating array of species for studying natural history, natural products chemistry, community ecology, and evolutionary biology. The diversification of this taxon is unique and of great importance in understanding the evolution of plants. The diversity and ecological relevance of this genus makes it an obvious candidate for ecological and evolutionary studies, but surprisingly, most research on Piper spp. to-date has focused on the more economically important plants P. nigrum (black pepper), P. methysticum (kava), and P. betle (betel leaf). While this book does address the applied techniques of studying Piper, its focus is more on Piper in its natural setting. Piper: A Model Genus for Studies of Phytochemistry, Ecology, and Evolution synthesizes existing data and provides an outline for future investigations of the chemistry, ecology, and evolution of this taxon, while examining its key themes of Piper as a model genus for ecological and evolutionary studies, the important ecological roles of Piper species in lowland wet forests, and the evolution of distinctive Piper attributes. This volume has a place in the libraries of those studying or working in the fields of ecology, evolutionary biology, natural products chemistry, invasive species biology, pharmaceutics, and ethnobotany.

This book is an update of Interferon, published in 1969 by Dr. Jan Vilcek. The field of interferon research has since expanded from its former narrow treatment of interferon strictly as an antiviral substance, such that The Interferon System now encompasses cellular modulations ranging from immune alterations to cell proliferative restrictions to antitumor activities. The steadily increasing number of these non-antiviral functions of interferons emphasizes the need for a comprehensive - and critical - review of the entire literature of interferon studies. The text, with its supporting bibliography, provides complete coverage of interferon research. A newcomer to the area should find here all the informa tion necessary to understand why interferon, which has been studied for more than twenty years and which originally stirred excitement over its clinical pros pects, is still inspiring speculation about this potential. For those already fa miliar with the seemingly perpetual clinical promise of interferon, this volume should serve as a valuable reference source, the largest bibliography on the subject ever to appear under one cover. Clearly, this book should be considered only as an introduction to the topic and as a reference source; most questions about the interferon system are still unanswered - even unasked. Hopefully this summation and critical evalua tion of work done to date will stimulate and facilitate further progress.

Advancing with Biomedical Engineering Today, in most developed countries, modem hospitals have become centers of sophis ticated health care delivery using advanced technological methods. These have come from the emergence of a new interdisciplinary field and profession, commonly referred to as "Bio medical Engineering." Although what is included in the field of biomedical engineering is quite clear, there are some disagreements about its definition. In its most comprehensive meaning, biomedical engineering is the application of the principles and methods of engi neering and basic sciences to the understanding of the structure-function relationships in normal and pathological mammalian tissues, as well as the design and manufacture of prod ucts to maintain, restore, or improve tissue functions, thus assisting in the diagnosis and treat ment of patients. In this very broad definition, the field of biomedical engineering now includes: * System analysis (modeling, simulation, and control of the biological system) * Biomedical instrumentation (detection, measurement, and monitoring of physio logic signals) * Medical imaging (display of anatomic details or physiologic functions for diag nosis) * Biomaterials (development of materials used in prostheses or in medical devices) * Artificial organs (design and manufacture of devices for replacement or augmen tation of tissues or organs) * Rehabilitation (development oftherapeutic and rehabilitation procedures and de vices) * Diagnostics (development of expert systems for diagnosis of diseases) * Controlled drug delivery (development of systems for administration of drugs and other active agents in a controlled manner, preferably to the target area)

While advances in modem medicine largely parallel our understanding of morphology, discoveries in morphology are propelled by developments of new tools and means to visualize and measure tissue elements. The invention of dissecting, light, fluorescence and electron microscopes together with advances in labeling and staining techniques are among the stepping stones of morphological progress. Today, we are in an exciting new era when classical morphology is being combined with developments from other disciplines. The combination of morphology and immunology resulted in immunocytochemistry; morphology and molecular biology led to in situ hybridization and in situ PCR. Adding computer science to morphology gave birth to image analysis. Combining laser technology and the microsope evolved into confocal microscope. For more than a decade, modem morphology has continued to develop by merging with other disciplines at a rate that is still gathering momentum, providing exciting and dynamic new frontiers for other biological fields. "Modem Methods in Analytical Morphology," based largely on the "First International Workshop on Modem Methods in Analytical Histochemistry, "is an updated review of the current trends in the field. It covers an extensive array of new technical developments in major disciplines of modem morphology. The authors are not only leaders in their fields but also have extensive "hands on" experience with "bench work. " Their chapters are written in a comprehensive manner including discussion of both theoretical considerations and practical applications to give the readers a broad view of the topics covered.

The discovery of mammalian nitric oxide (NO-) synthesis from I-ar- ginine has led to profound increases in our understanding of basic physiological and pathophysiological processes. This understanding has been achieved by major advances in several areas. Three major ni- tric oxide synthase (NOS) isoforms have been identified at the protein and gene level and their specific tissue localization has been linked to processes subject to regulation by NO-. The molecular basis for the di- verse effects of NO- on cell function has been shown to derive from its chemical reactivity with oxygen-containing species and both heme and non-heme iron-dependent enzymes. The potential regulation of heme- dependent enzymes such as cytochromes P450, guanylate cyclase, cy- clooxygenase, and mitochondrial cytochrome oxidase continues to emerge as a key area in NO- research. In addition, it has become clear that the expression of NOS isoforms and NO- release from cells is subject to regulation by sexual steroids and that, in tum, NO- has the potential to regulate steroid biosynthesis via inhibition of cytochromes P450 involved in steroidogenesis. These recent observations on interactions between the NO-/NOS and cytochrome P450/sexual steroid pathways have important implica- tions for understanding fundamental mechanisms involved in endocri- nological processes. They are also likely to lead to novel insights and novel therapeutic approaches for the management of pathophysiologi- cal conditions associated with alterations in sexual steroid hormones.

State-of-the-Art Chirality Stereochemistry in general and chirality in particular have long been recog- nized as major structural factors influencing pharmacological activity and pharmacokinetic behavior. For more than a century, relevant information in these fields has been accumulating at an accelerating pace, leading to rationalizations, concepts and theories of increasing breadth and depth. Frequently, fundamental advances in stereochemical aspects of molecular pharmacology, drug disposition and pharmacochemistry have been translated into corresponding progress in clinical pharmacology and pharmacotherapy. There have been exceptions, however, since some extrapolations from the biochemical and in vitro situations to the in vivo human situation have proven premature. This notion resulted in the now appeased, but far from closed, debate regarding racemic versus enantiopure drugs, which saw some pro- ponents state that "in many cases, only one isomer contributes to the thera- peutic action while the other, the 'isomeric ballast', only contributes to the side effects and toxicity" (ARIENS 1986,1989,1992). Other authors, in contrast, have cautioned against hasty generalizations and advocated a more pragmatic, case- by-case and evidence-based view (CALDWELL 1995; DE CAMP 1989; SZELENYI et al. 1998; TESTA 1991; TESTA and TRAGER 1990; TESTA et al. 1993).
