Prostaglandins and Thromboxanes explores the two members of the prostanoid class of fatty acid. This book attempts to thoroughly discuss the topic after collecting enough information through research in physical and biological sciences. As the title suggests, the book revolves around prostaglandins and thromboxanes. The book's first chapter contains a discussion on the subject's history, stating the year of discovery and crediting the scientist who coined the names. The chapter ends talking about the possible uses of prostaglandins and thromboxanes in the clinic. The chapters that follow discu...
Biochemical Aspects of Prostaglandins and Thromboxanes covers the proceedings of the 1976 Intra-Science Research Foundation Symposium on New Biochemistry of Prostaglandins and Thromboxanes, held in Santa Monica, California. This 14-chapter book deals first with the biosynthesis of prostaglandins and thromboxanes with bovine vesicular gland and in transformed fibroblasts. These topics are followed by discussions on the pharmacologic properties and the role of prostaglandins as mediators of the inflammatory response. The next chapters describe the structure-activity relations and the pharmacologic activities of the prostaglandin series, with an emphasis on their role in cancer, obstetrics, and gynecology. The remaining chapters examine the role of prostaglandin endoperoxides and thromboxanes as bioregulators. This book will be of value to biochemists and pharmacologists.

Prostaglandins, Leukotrienes, and Cancer is a multi-volume series that will focus on an emerging area of cancer research. In 1968, R.H. Williams first reported that elevated prostaglandin levels are present in human medullary car­ cinoma. Since that time, the concept that arachidonic acid metabolites may be in­ volved in cancer has expanded to include every aspect of the disease from cell transformation through metastasis. Prostaglandins and leukotrienes are generic terms used to describe a family of bioactive lipids produced from unsaturated fatty acids (principally from arachidonic acid) via the cyclooxygenase and lipoxygenase pathways, respec­ tively. Cyclooxygenase products consist of diverse products such as prosta­ glandin E, (POE,), prostacyclin (POI2) and thromboxane A2 (TXA2), whereas lipoxygenase products consist of hydroperoxy fatty acids and mono-, di- and tri-hydroxy acids including leukotrienes. The precursor fatty acids for the cyclooxygenase and lip oxygenase pathways are present in cellular phospholipids. This finding established an important control point in their biosynthesis-the release of substrate. This occurs in response to numerous stimuli that act at the cell surface. Dr. Bengt Samuelsson's extensive study of the metabolism of pros­ taglandins indicated that they are rapidly inactivated on a single pass through pulmonary circulation. Thus, they cannot act as circulating hormones and appear to be made on demand in or in the vicinity of target tissues leading to the concept that prostaglandins are local hormones or autocoids.
This comprehensive reference work, updated from the first edition, brings together the knowledge and expertise of contributors from around the world. It includes new topics such as prostaglandin synthetase enzyme, new synthetic eicosanoids, innovative analytical methods, the influence of cytokines in the regulation of synthesis and actions, newer eicosanoids that influence the cardiovascular system, and newly discovered roles in reproduction and interactions with nitric oxide. This book satisfies a surge of interest in prostaglandins—NSAIDS (e.g. aspirin) are the biggest selling drugs of all time, and the field has been refreshed by the advent of new types (selective COX-2 inhibitors, anti-leukotiene drugs).
The Second Edition of Asthma and COPD: Basic Mechanisms and Clinical Management continues to provide a unique and authoritative comparison of asthma and COPD. Written and edited by the world's leading experts, it continues to be a comprehensive review of the most recent understanding of the basic mechanisms of both conditions, specifically comparing their etiology, pathogenesis, and treatments. * Each chapter considers Asthma and COPD in side-by-side contrast and comparison – not in isolation - in the context of mechanism, triggers, assessments, therapies, and clinical management * Presents the latest and most comprehensive understandings of the mechanisms of inflammation in both Asthma and COPD * Most extensive reference to primary literature on both Asthma and COPD in one source. * Easy-to-read summaries of the latest advances alongside clear illustrations
This volume presents lecture notes from the session of the International School of Pharmacology, at the "Ettore Majorana" Centre, on Advances in Prostaglandins that took place in Erice (Sicily), October 4 to October 15, 1976. The School was a NATO Advanced Study Institute. The aim of this international course was a compre­ hensive discussion by experts in various disciplines of the present status of our knowledge of the biological role of prostaglandins and thromboxanes. The synthesis, metabolism, and function of prosta­ glandins have been evaluated at the cellular level, in isolated tissues, and/or in the intact organism. The mode of action of prostaglandins and their interactions, particularly with cyclic nucleotides, in normal and pathological conditions, has been discussed with the aim of understanding the possible role of these compounds in hormonal regulation and cell response. The prostaglandin biosynthetic capacity of different tissues, under various experimental conditions, in the presence of specific precursors, and the inhibitory ac­ tivity of different agents have been examined to ascer­ tain the relationship between function and metabolism. For these reasons the discussion has also been extended to the methods (biological, immunological, and spectrometric) available for the direct and specific determination of prostaglandins and the evaluation of their synthesis and metabolism. The Editors hope that the book will be useful both to beginners and to those with a long-time interest in prostaglandins. F. Berti B. Samuelsson G. P.

Bones and Cartilage provides the most in-depth review and synthesis assembled on the topic, across all vertebrates. It examines the function, development and evolution of bone and cartilage as tissues, organs and skeletal systems. It describes how bone and cartilage develop in embryos and are maintained in adults, how bone is repaired when we break a leg, or regenerates when a newt grows a new limb, or a lizard a new tail. The second edition of Bones and Cartilage includes the most recent knowledge of molecular, cellular, developmental and evolutionary processes, which are integrated to outline a unified discipline of developmental and evolutionary skeletal biology. Additionally, coverage includes how the molecular and cellular aspects of bones and cartilage differ in different skeletal systems and across species, along with the latest studies and hypotheses of relationships between skeletal cells and the most recent information on coupling between osteocytes and osteoclasts All chapters have been revised and updated to include the latest research. - Offers complete coverage of every aspect of bone and cartilage, with updated references and extensive illustrations - Integrates development and evolution of the skeleton, as well a synthesis of differentiation, growth and patterning - Treats all levels from molecular to clinical, embryos to evolution, and covers all vertebrates as well as invertebrate cartilages - Includes new chapters on evolutionary skeletal biology that highlight normal variation and variability, and variation outside the norm (neomorphs, atavisms) - Updates hypotheses on the origination of cartilage using new phylogenetic, cellular and genetic data - Covers stem cells in embryos and adults, including mesenchymal stem cells and their use in genetic engineering of cartilage, and the concept of the stem cell niche
Chemical Intolerance identifies phenolic (aromatic) chemical compounds present in natural foodstuffs, pollens, certain food additives, tobacco smoke, perfumes, air pollution, etc., as nonimmunologic, but pharmacologic activators of allergic reactions in chemically intolerant individuals. Biochemical pathway sequences, with supporting scientific literature, are outlined to elucidate the mechanisms associated with formation of inflammatory mediators (prostaglandins, thromboxanes, and leukotrienes) upon activation by phenolic compounds and other chemical stimulants. The role of these inflammatory agents in respiratory, gastrointestinal, neurological, cardiovascular, and other disorders is discussed. Treatment modalities using precise dosages of selected phenolic compounds are outlined to provide clinicians with an effective means of therapy. The author also shares his own experience and personal findings based on 20 years of research, including his recommendations for therapy.
