Buch. Condición: Neu. Neuware - Radiochemical methodology constitutes the most important base for the successful functioning of a PET group in the routine production and development of radiopharmaceuticals. Of the several hundred products which have been labelled with positron emitters during the past two decades about 35 are presently considered to be of major interest. The time for a state-of-the-art review is right, since this field has advanced over the past fifteen years to reach a level where guidelines can now be suggested. Chapters of this book deal with each of the main methodological aspects of the chemistry needed to develop an effective radiopharmaceutical, namely radionuclide production, automation and metabolite analysis. A further chapter on QA/QC is written by a broadly-based expert group and is meant to provide a guideline and a base for future monographs and regulations on major PET radiopharmaceuticals of today. This book will help the increasing numbers of scientists who are now entering the field of PET to appreciate the methodological aspects that are normally addressed by chemists in relation to PET radiopharmaceuticals; it provides many useful practical guidelines and will promote early success in their own endeavours, since these will often necessarily begin by establishing chemical methodology of the kind discussed here.…

Due to their physiology, morphology and complex life cycles, amphibian species are often highly habitat-specific and particularly threatened by environmental changes. Currently more than one third of all species is believed to be threatened. The worldwide decline of amphibians therefore has become a symbol for the Global Biodiversity Crisis. Whereas in recent years many studies have reported the threat status of amphibians in the northern hemisphere, Latin America and Australia, very little information was available for Africa, in particular for sub-Saharan Africa. This book illustrates the beauty of Afrotropical amphibians as well as their habitats and threats, summarizing our previous knowledge and presenting new facts concerning the status, threats and potential future of amphibians in all sub-Saharan countries, Madagascar and western Indian Ocean islands. It will serve as a guideline for conservationists, decision makers and researchers, and due to its lavishly illustrated layout, will also be attractive to everybody interested in African amphibians in particular and amphibian biology and conservation in general.
