Progress in medicine has often been initiated by discoveries and results from various disciplines of natural science. One of the most famous examples is the X-ray. In this case, its importance with respect to medical applications was immediately recognized and its development was propelled by fruitful cooperation between physicians and physicists. In other cases, e.g. that of NMR, the period between discovery and subsequent application in medicine was longer. Sometimes, a method has become established in clinical practice only after having passed through a long period of in vitro investigations and preclinical trials, while there are also applications that could only be seriously developed once crucial parts had been invented. <p> Such cooperation between physicians, scientists, and engineers has proven effective and is certainly also a prerequisite for the continuing development of new methods or more sophisticated techniques and instruments. This is of particular concern for the application of magnetism in medicine. <p> This second, completely updated and extended edition of the only reference work in this growing field of medical physics focuses on biomagnetic instrumentation as well as applications in cardiology and neurology. New chapters have been added on fetal magnetography and magnetic field therapy, as well as the safety aspects of magnetic fields. Following an introductory section, the well-known specialist authors from Germany, USA, Canada, Japan, the Netherlands and Scandinavia go on to cover biomagnetism, magnetic resonances, as well as magnetic substances and externally applied magnetic fields, before rounding the text off with a set of conclusions. <p> The result is a manual for researchers in this field as well as for those who apply modern methods based on magnetism in medical practice. It equally provides a detailed overview for newcomers to the field as well as for experts familiar with only one part of the area.
Dr Hahnemann's masterpiece "Organon of Medicine" involves study of inductive philosophy. The Lord Bacon's principle of inductive logic has been applied in the study of natural phenomenon of health, disease and action of medicine. It requires a great effort by all students of homeopathy to learn and follow it in the manner the founder of homeopathy had desired. The author's work is a humble contribution towards the understanding of this complex but most vital subject of homeopathy.
Medicinal chemistry is both science and art. The science of medicinal chemistry offers mankind one of its best hopes for improving the quality of life. The art of medicinal chemistry continues to challenge its practitioners with the need for both intuition and experience to discover new drugs. Hence sharing the experience of drug research is uniquely beneficial to the field of medicinal chemistry. Drug research requires interdisciplinary team-work at the interface between chemistry, biology and medicine. Therefore, the topic-related series Topics in Medicinal Chemistry covers all relevant aspects of drug research, e.g. pathobiochemistry of diseases, identification and validation of (emerging) drug targets, structural biology, drugability of targets, drug design approaches, chemogenomics, synthetic chemistry including combinatorial methods, bioorganic chemistry, natural compounds, high-throughput screening, pharmacological in vitro and in vivo investigations, drug-receptor interactions on the molecular level, structure-activity relationships, drug absorption, distribution, metabolism, elimination, toxicology and pharmacogenomics. In general, special volumes are edited by well known guest editors.
This unique book is the first comprehensive guide to the discovery, analysis, and evaluation of natural experiments - an increasingly popular methodology in the social sciences. Thad Dunning provides an introduction to key issues in causal inference, including model specification, and emphasizes the importance of strong research design over complex statistical analysis. Surveying many examples of standard natural experiments, regression-discontinuity designs, and instrumental-variables designs, Dunning highlights both the strengths and potential weaknesses of these methods, aiding researchers in better harnessing the promise of natural experiments while avoiding the pitfalls. Dunning also demonstrates the contribution of qualitative methods to natural experiments and proposes new ways to integrate qualitative and quantitative techniques. Chapters complete with exercises and appendices covering specialized topics such as cluster-randomized natural experiments, make this an ideal teaching tool as well as a valuable book for professional researchers.
This is the fourth volume of Ultrasound in Medicine, the Proceedings of the Annual Scientific Meeting of the American Institute of Ultrasound in Medicine. Unless the Executive Board of the Institute change their mind, it may also be the last. Under these circumstances it is somewhat ironical that some of the deficiencies present in previous volumes appear to have been solved in the present volume. Notably, the Programme Committee, for the first time, exercised a stringent selection procedure by means of which the number of papers selected for presentation was limited with the result that both the quality of papers accepted for presentation and publication was improved and the number of simultaneous sessions at the meeting did not exceed two. The contents of this volume have been divided into the same sections as in previous volumes except that no papers on stan- dardization procedures were accepted and a new supplementary section is added consisting of papers given at the Scientific Meeting of the American Society of Ultrasound Technical Specia- lists. As in previous editions the readers may consider the engin- eering sections at the end of this volume are the most rewarding. Some ingenious new systems are described both in the sections on Doppler techniques and new techniques. Current interest in tissue signatures and characterization are reflected in many of the pap~rs appearing in the Tissue Interactions section.
