The nonsurgical management of gallstone disease has drawn widespread clinical interest during the last decade as ultrasound surveys have indicated that cholelithiasis is predom inantly an asymptomatic condition and much more prevalent than previously thought. This book presents an overview of the pathophysiologic and pathobiochemical principles of gallstone formation and the consequences for clinical therapeutic regimens. New information concerning the balance between vesicular and micellar transport of choles terol, early cholesterol nucleation, and the influence of inhibiting and promoting com pounds for cholesterol nucleation as well as information concerning the effects of changes in gal...
A variety of new cancer therapy modalities are discussed and evaluated in this book. It aims to demonstrate that the combination of classical chemo- and radiotherapy with new approaches in the field of immunotherapy can result in an improved treatment modality. Immunotherapy in this context consists of therapy with monoclonal antibodies, hematopoietic growth factors and other lymphokines. Results of early clinical trials with IL-2, GM-CSF and monoclonal antibodies against gastrointestinal tumors and melanoma are included. The progress in regional chemotherapy strategies, for example of the liver, is shown. In addition, the development of new chemotherapeutic agents with a different mode of action as well as better tolerability is presented. The use of hormones, such as LH-RH agonists, allows hormone-dependent tumors such as prostatic and breast cancer to be treated without strong adverse reactions. These recent findings give the reader insight into exciting therapeutic directions made possible by such combined, rather than single, modalities.
Lasers in Dermatology presents an excellent and complete survey of the numerous applications of lasers in dermatological therapy and research, the fundamentals of laser-skin interaction, and the various laser sources and tools in use. A comprehensive outlook to new instrumentation, such as pulsed lasers of ultraviolet and infrared wavelengths, completes this up-to-date overview, which is indispensable not only to practitioners and clinical researchers in dermatology but also to engineers and laser physicists in biomedicine.
Over a decade has elapsed since the last volume in this series was published. At that time we considered that we had comprehensively covered all aspects relating to bile acid chemistry and physiology. However, major strides have been made in our understanding of the physiology and pathophysiology of bile acids, due largely to the great advances which have taken place in analytical technology. As a result, the need to document these advances was felt acutely, and therefore this volume is devoted to methodologies in bile acid analysis and their applications. This volume includes twelve chapters written by prominent scientists in the field of bile acid research. The initial chapter discusses te...
Exciting major changes have occurred in the understanding and treatment of gallstone disease over the last two decades. In bygone years, books about gallstones were often based on postgraduate lectures which the author, usually a surgeon of distinction, had given. More recently, many books dealing with this subject have been based upon national or international conferences. The single-author text has the disadvantage that few authors today can authoritatively encompass a whole field: the reports of symposia, conferences or workshops often lack balance and auth ority. The merits of 'Gallstone disease and its Management' edited by Malcolm Bateson are clear. He has chosen 11 authors, all of who...
The number of Americans eligible to receive Social Security benefits will increase from forty-five million to nearly eighty million in the next twenty years. Retirement systems must therefore adapt to meet the demands of the largest aging population in our nation’s history. In Developments in the Economics of Aging, David A. Wise and a distinguished group of analysts examine the economic issues that will confront policy makers as they seek to design policies to protect the economic and physical health of these older Americans. The volume looks at such topics as factors influencing work and retirement decisions at older ages, changes in life satisfaction associated with retirement, and the shift in responsibility for managing retirement assets from professional money managers of traditional pension plans to individual account holders of 401(k)s. Developments in the Economics of Aging also addresses the complicated relationship between health and economic status, including why health behaviors vary across populations and how socioeconomic measures correlate with health outcomes.
In 1949 the U.S. National Cancer Institute (NCI) and the Canadian Department of National Health and Welfare (DNHW) commissioned a film, eventually called Challenge. Science Against Cancer, as part of a major effort to recruit young scientists into cancer research. Both organizations feared that poor recruitment would stifle the development of the field at a time when funding for research was growing dramatically. The fear was that there would not be enough new young scientists to meet the demand, and that the shortfall would undermine cancer research and the hopes invested in it. Challenge aimed to persuade young scientists to think of cancer research as a career. This book is the story of t...
Reports of the beneficial health effects of some peptides have begun to make their way into the scientific literature. Peptides can act as immunomodulators, and have been shown to have a positive influence on calcium absorption, and on regulation of serum cholesterol. A number of peptides may also possess antimicrobial properties that enhance the b
