Mineralstoffe und Spurenelemente sind unverzichtbare Bestandteile oder Kofaktoren in nahezu allen Stoffwechselwegen. Allerdings werden die optimalen Aufnahmemengen oft kontrovers diskutiert. Essentielle Funktionen sowie Nutzen-Risiko-Betrachtungen unter Einbeziehung von Nahrungsergänzungsmitteln werden am Beispiel von Iod, Zink, Eisen, Selen, Mangan und Kupfer dargestellt. Ferner werden toxische Wirkungen von Verbindungen der Halbmetalle Arsen und Antimon beschrieben.

Die Jahrestagungen der Gesellschaft für Mineralstoffe und Spurenelemente e .V. (GMS) behandeln Themen an den Schnittstellen zwischen Medizin, Ernährung, Biologie, Chemie und Umwelt. Dieses Buch präsentiert die Beiträge zur 28. Jahrestagung der GMS am Karlsruher Institut für Technologie. Unter dem Motto "Nutzen-Risiko-Bewertung von Mineralstoffen und Spurenelementen: Biochemische, physikalische und toxikologische Aspekte"wurden neueste Erkenntnisse aus dem Bereich der Spurenelemente präsentiert. Am Beispiel von Zink, Selen, Jod und Eisen wurden biochemische Funktionen, eine optimale Aufnahme/Versorgung sowie Interaktionen zwischen diesen Spurenelementen dargestellt. Andererseits müssen aber auch möglicherweise toxische Wirkungen von Spurenelementen infolge von Überversorgung, beispielsweise durch Nahrungsergänzungsmittel oder angereicherte Lebensmittel, in Betracht gezogen und durch entsprechende Grenzwertsetzung berücksichtigt werden. Toxische Wirkungen können zudem als Folge unphysiologischer Aufnahmewege auftreten; Beispiele sind die Neurotoxizität von Mangan und schädigende Wirkungen von Kupfer-basierten Nanopartikeln. Für Arsen standen der Metabolismus sowie die Speziesabhängigkeit toxischer Effekte im Fokus des Interesses. Die Zusammenschau analytischer, biochemischer und toxikologischer Aspekte liefert einen Eindruck über das spannende Forschungsgebiet der Spurenelemente.

The essays collected in this volume explore some of the themes that have been at the centre of recent debates within Wittgensteinian scholarship. In opposition to what we are tentatively inclined to think, the articles of this volume invite us to understand that our need to grasp the essence of ethical and religious thought and language will not be achieved by metaphysical theories expounded from such a point of view, but by focusing on our everyday forms of expression.

The model for risk assessment of nutrients used to develop tolerable upper intake levels (ULs) is one of the key elements of the developing framework for Dietary Reference Intakes (DRIs). DRIs are dietary reference values for the intake of nutrients and food components by Americans and Canadians. The U.S. National Academy of Sciences recently released two reports in the series (IOM, 1997, 1998). The overall project is a comprehensive effort undertaken by the Standing Committee on the Scientific Evaluation of Dietary Reference Intakes (DRI Committee) of the Food and Nutrition Board (FNB), Institute of Medicine, National Academy of Sciences in the United States, with active involvement of Health Canada. The DRI project is the result of significant discussion from 1991 to 1996 by the FNB regarding how to approach the growing concern that one set of quantitative estimates of recommended intakes, the Recommended Dietary Allowances (RDAs), was scientifically inappropriate to be used as the basis for many of the uses to which it had come to be applied.

The risk assessment approach described in this monograph applies only to essential trace elements (ETEs) involved in human health and not to non-essential elements. The purpose of this monograph is to provide the scientific principles that support the concept of an acceptable range of oral intake (AROI) which uses a homeostatic model for determining the range of dietary intakes for essential trace elements (ETEs) that meet the nutritional requirements of a healthy population and avoid excess intakes. To facilitate comparisons AROIs are discussed in relation to other risk assessment approaches. Although it includes examples this monograph is not a compendium of assessments on ETEs nor is it a textbook detailing the scientific basis of risk assessment of the derivation of dietary reference intakes. Described in the book is the process of risk assessment which begins with the selection of the database for a particular ETE. A weight-of-evidence approach is then used for hazard identification selecting relevant end-point of deficient and excess exposures. Next the probability of risk and the severity of various effects are quantified and critical effects are selected. The AROI is then established by balancing end-points of comparable health significance. At this time the exposure assessment is conducted. Finally a risk characterization enumerating the strengths and weaknesses of the databases is performed integrating the AROI and exposure assessment. ... The amount of work which is entailed in these volumes is very great and the low cost does not reflect the time of experts travelling nor even the hours expended UN staff in Geneva... This well informed book with its predecessors in the series is essential reading for biologists chemists and medical professionals concerned with essential trace elements. - The International Journal of Environmental Studies

The emergence of a global and technological world and its accelerating, dissemination before the beginning of the 21st century does not only give rise to technological, economic, social, environmental, political, and educational tasks. Significant philosophical questions, epistemic reflections, and cultural debates result. The aim of this book is to provide information about epistemic, ethical, and cultural implications of sustainable development on an interdisciplinary and international level.

Effective Research Data Management (RDM) is a key component of research integrity and reproducible research, and its importance is increasingly emphasised by funding bodies, governments, and research institutions around the world. However, many researchers are unfamiliar with RDM best practices, and research support staff are faced with the difficult task of delivering support to researchers across different disciplines and career stages. What strategies can institutions use to solve these problems? Engaging Researchers with Data Management is an invaluable collection of 24 case studies, drawn from institutions across the globe, that demonstrate clearly and practically how to engage the research community with RDM. These case studies together illustrate the variety of innovative strategies research institutions have developed to engage with their researchers about managing research data. Each study is presented concisely and clearly, highlighting the essential ingredients that led to its success and challenges encountered along the way. By interviewing key staff about their experiences and the organisational context, the authors of this book have created an essential resource for organisations looking to increase engagement with their research communities. This handbook is a collaboration by research institutions, for research institutions. It aims not only to inspire and engage, but also to help drive cultural change towards better data management. It has been written for anyone interested in RDM, or simply, good research practice.

This volume brings together a collection of seven articles previously published by the author, with a new introduction reframing the articles in the context of past and present questions in anthropology, psychology and human evolution. It promotes the perspective of ‘integrated’ social science, in which social science questions are addressed in a deliberately eclectic manner, combining results and models from evolutionary biology, experimental psychology, economics, anthropology and history. It thus constitutes a welcome contribution to a gradually emerging approach to social science based on E. O. Wilson’s concept of ‘consilience’. Human Cultures through the Scientific Lens spans a wide range of topics, from an examination of ritual behaviour, integrating neuro-science, ethology and anthropology to explain why humans engage in ritual actions (both cultural and individual), to the motivation of conflicts between groups. As such, the collection gives readers a comprehensive and accessible introduction to the applications of an evolutionary paradigm in the social sciences. This volume will be a useful resource for scholars and students in the social sciences (particularly psychology, anthropology, evolutionary biology and the political sciences), as well as a general readership interested in the social sciences.
