The action of diuretics including cellular mechanisms of action, pharmacokinetics, and clinical usage, with much emphasis placed on the most recent findings on the pharmacodynamics of the respective drugs. During the past twenty-five years since volume 14 on Diuretica was published in the Handbook series, the cellular mechanisms of action of diuretics have slowly been unravelled. Today, the role of action within the target cells is known for most of the substances discussed. This has provided a new basis not only for the understanding of drug action but also for secondary effects and interactions. The book represents a comprehensive reference work on the diverse groups of diuretics which are among the most frequently prescribed medications.

According to the great mathematician Paul Erdös, God maintains perfect mathematical proofs in The Book. This book presents the authors candidates for such "perfect proofs," those which contain brilliant ideas, clever connections, and wonderful observations, bringing new insight and surprising perspectives to problems from number theory, geometry, analysis, combinatorics, and graph theory. As a result, this book will be fun reading for anyone with an interest in mathematics.

If it is true that science proceeds from a romantic through a scientific to a technological stage, then research on bird orientation is certainly on its move from its first to its second grade, and recent developments in radiotelemetry and satellite tracking of migrating birds might already indicate the advent of the third stage. At this juncture, Orientation in Birds is a timely account. Even though the study of animal migration in general, and bird navigation in particular, has produced a literature of impressive proportions, the threads provided by the plethora of research papers, review articles and symposiums volumes have not yet been knitted into a theoretical fabric. This is partly due to our still incomplete understanding of fundamen tal topics in avian navigation. The answer to the most intriguing question of how a bird displaced to "unknown" territory finds its way back home is as obscure now as it was a few decades ago. Whether and how birds solve this problem by using far ranging grid-maps or more local familiar-area maps, as has been proposed off and on, is still a matter of heated debates. These debates frequently center around provocative hypotheses - let alone the question about the physical (topographic, magnetic, infrasonic, olfactory) parameters which might constitute such maps.

This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.

Ascidians are the invertebrate group that gave rise to vertebrates, thus the biology of ascidians provides an essential key to understanding both invertebrates and vertebrates. This book is the first to cover all areas of ascidian biology, including development, evolution, biologically active substances, heavy metal accumulation, asexual reproduction, host-defense mechanisms, allorecognition mechanisms, comparative immunology, neuroscience, taxonomy, ecology, genome science, and food science. The 69 articles that make up the collection were contributed by leading ascidiologists from all over the world who participated in the First International Symposium on the Biology of Ascidians, held in June 2000 in Sapporo, Japan. For scientists and students alike, the book is an invaluable source of information from the latest, most comprehensive studies of ascidian biology.

Europe is the cradle of the modem international chemical industry. From the middle of the nineteenth century until the outbreak of World War I, the European chemical industry influenced not only the production and control of science and technology, but also made significant contributions towards economic development, as well as bringing about profound changes in working and living enviromnents. It is a highly complex heritage, both rich and threatening, that calls for close scrutinity. Fortunately, a unique opportunity to explore the historical development of the European chemical industry from a variety of novel standpoints, was made possible during 1993 as part of the European Science Foundation (ESF) programme called 'The Evolution of Chemistry in Europe, 1789-1939.' This process of exploration has taken place through three workshops, each dealing with different time periods. The workshop concerned with the period 1850-1914, which corresponds roughly to the so-called Second Industrial Revolution, was held in Maastricht, The Netherlands, on 23-25 March 1995. This volume is the outcome of that workshop. The other workshops dealing with European chemical industry were held in Liege in 1994, covering the First Industrial Revolution period, 1789-1850, and Strasbourg in 1996, covering the period between the two World Wars.

Significant recent advances in the imaging of the lower urinary tract are comprehensively presented in this handbook. It offers information on both imaging examinations and interventional techniques with all the modern modalities, including MRI and ultrasound. The contributors are all experts in clinical urology; their varying and at times conflicting opinions track the fast-moving pace in the field and demonstrate the complexity of the subject. The approach is disease-oriented, though grouped by anatomic region. Each chapter covers etiology, physiology, pathology, epidemiology, clinical presentations and especially diagnostic imaging, but also the appropriate interventional radiologic techniques for both diagnosis and treatment.

Many times drugs work fine when tested outside the body, but when they are tested in the body they fail. One of the major reasons a drug fails is that it cannot be absorb by the body in a way to have the effect it was intended to have. Permeability, Solubility, Dissolution, and Charged State of Ionizable Molecules: Helps drug discovery professionals to eliminate poorly absorbable molecules early in the drug discovery process, which can save drug companies millions of dollars. Extensive tabulations, in appendix format, of properties and structures of about 200 standard drug molecules.
