Cet ouvrage répond aux questionnements scientifiques posés sur les effets biologiques des phytomicronutriments (polyphénols, phytostérols, caroténoïdes, glucosinolates…), dans le double contexte de transition nutritionnelle et du vieillissement de la population, et dans le cadre du rôle potentiel de notre alimentation dans la gestion de notre santé. Fruit d'un travail collectif initié par l'Institut français pour la nutrition (IFN) Les phytomicronutriments présente : - une classification des différentes familles de phytomicronutriments, - les principaux facteurs de variation impactant sur les quantités ingérées et sur leur biodisponibilité, car les effets santé des phytomicronutriments dépendent de leurs niveaux de consommation et de leur biodisponibilité, - leur fonctionnalité puis leur impact dans des populations spécifiques (femmes ménopausées, sportifs et personnes âgées), - les bénéfices/risques de quelques classes de molécules, les plus étudiées : phyto-oestrogènes, phytostérols et caroténoïdes, - une illustration de la composition en phytomicronutriments dans des menus types et la possibilité de les repérer dans les aliments sur la base de la couleur de ces derniers. Cet ouvrage s'adresse aux scientifiques, aux professionnels de l'industrie alimentaire, aux professionnels de la santé, aux enseignants et aux étudiants dans le domaine de la nutrition et de la santé.

Interest in the science of exercise dates back to the time of ancient Greece. Today exercise is viewed not only as a leisurely activity but also as an effective preventive and therapeutic tool in medicine. Further biomedical studies in exercise physiology and biochemistry reports that strenuous physical exercise might cause oxidative lipid damage in various tissues. The generation of reactive oxygen species is elevated to a level that overwhelms the tissue antioxidant defense systems resulting in oxidative stress.The Handbook of Oxidants and Antioxidants in Exercise examines the different aspects of exercise-induced oxidative stress, its management, and how reactive oxygen may affect the functional capacity of various vital organs and tissues. It includes key related issues such as analytical methods, environmental factors, nutrition, aging, organ function and several pathophysiological processes.This timely publication will be of relevance to those in biomedical science and was designed to be readily understood by the general scientific audience.

determined by an inability to move in response to touch. C. elegans develop through four larval stages following hatching and prior to adulthood. Adult C. elegans are reproductive for about the rst week of adulthood followed by approximately two weeks of post-reproductive adulthood prior to death. Life span is most commonly measured in the laboratory by maintaining the worms on the surface of a nutrie- agar medium (Nematode Growth Medium, NGM) with E. coli OP50 as the bacterial food source (REF). Alternative culture conditions have been described in liquid media; however, these are not widely used for longevity studies. Longevity of the commonly used wild type C. elegans hermaphrodite (N2) varies ? from 16 to 23 days under standard laboratory conditions (20 C, NGM agar, E. coli OP50 food source). Life span can be increased by maintaining animals at lower ambient temperatures and shortened by raising the ambient temperature. Use of a killed bacterial food source, rather than live E. coli, increases lifespan by 2–4 days, and growth of adult animals in the absence of bacteria (axenic growth or bac- rial deprivation) increases median life span to 32–38 days [3, 23, 24]. Under both standard laboratory conditions and bacterial deprivation conditions, wild-derived C. elegans hermaphrodites exhibit longevity comparable to N2 animals [25].

The fourth edition of this well-received book offers a comprehensive update on recent developments and trends in the clinical and scientific applications of multislice computed tomography. Following an initial section on the most significant current technical aspects and issues, detailed information is provided on a comprehensive range of diagnostic applications. Imaging of the head and neck, the cardiovascular system, the abdomen, and the lungs is covered in depth, describing the application of multislice CT in a variety of tumors and other pathologies. Emerging fields such as pediatric imaging and CT-guided interventions are fully addressed, and emergency CT is also covered. Radiation exposure, dual-energy imaging, contrast enhancement, image postprocessing, CT perfusion imaging, and CT angiography all receive close attention. The new edition has been comprehensively revised and complemented by contributions from highly experienced and well-known authors who offer diverse perspectives, highlighting the possibilities offered by the most modern multidetector CT systems. This book will be particularly useful for general users of CT systems who wish to upgrade and enhance not only their machines but also their knowledge.

Epidemics and pandemics of infectious diseases are occurring more often, and spreading faster and further than ever, in many different regions of the world. The background factors of this threat are biological, environmental and lifestyle changes, among others. A potentially fatal combination of newly-discovered diseases, and the re-emergence of many long-established ones, demands urgent responses in all countries. Planning and preparation for epidemic prevention and control are essential. The purpose of the Managing epidemics handbook is to provide expert guidance on those response. Building on the first edition, the second edition provides concise and basic up-to-date knowledge with which World Health Organization country representatives can advise Ministries of Health to respond effectively and rapidly at the very start of an outbreak. Part I of the handbook provides insights on epidemics of the 21st century and offers context on the upsurge of recent epidemics. Part II has been updated and offers 10 key facts about 19 deadly diseases including tips on the interventions required to respond. Part III presents various Tool boxes that summarize guidance on several important topics. The handbook focuses on practical and indispensable things to know about infectious diseases that are most important for national, political and operational decision-makers; it also links readers to more exhaustive WHO guidance.

Selenium: Geobotany, Biochemistry, Toxicity, and Nutrition focuses on the properties, characteristics, reactions, applications, chemistry, and transformations of selenium. The book first offers information on the geological distribution of selenium, including the formation of seleniferous soils, chemical forms of selenium in soils, selenium in water, selenium on the sea floor and in sea water, and geobotany. The text then takes a look at selenium indicator in plants and accumulation of selenium by plants. Discussions focus on selenium accumulations in indicator plants; selenium accumulation in farm crops and native grasses; factors that influence selenium accumulation in plants; and identification of indicators by germination tests. The manuscript elaborates on selenium poisoning in animals and prevention and control of selenium poisoning. Acute selenium poisoning, chronic selenium poisoning by inorganic selenium, and recognition of poisonous range plants are also discussed. The text also examines selenium in nutrition and the chemistry of selenium. The publication is a valuable source of data for readers interested in the study of selenium.
