Comment réussir son vieillissement ? L'activité physique a un rôle prépondérant dans cette réussite ! Avec l'avancée en âge peuvent survenir des désagréments de santé, physique et psychologique. Outre les troubles chroniques (diabète, hypertension, excès de cholestérol) et les baisses de moral associées, nous faisons face à une diminution des capacités fonctionnelles (force, endurance, équilibre et souplesse) en lien avec le processus de dynapénie. La perte d'autonomie qui en découle est la principale crainte des Français liée au vieillissement. Pourtant, des solutions simples existent pour stopper cette spirale négative ! L'activité physique est un outil de prévention : elle ralentit les effets du vieillissement et protège des conséquences de la sédentarité. Elle est aussi un outil de traitement : il n'est jamais trop tard pour se mettre à bouger, dans la mesure de ses capacités, et améliorer sa qualité de vie et sa santé ! Avec des explications claires, des astuces pour modifier en douceur ses habitudes de vie et des exercices accessibles à faire chez soi, ce livre est un guide complet pour envisager un vieillissement serein et rester actif et indépendant pendant longtemps.

Lutter contre les effets du vieillissement avec l’activité physique adaptée : astuces et solutions pour bien vieillir ! De nos jours, le vieillissement de la population est une problématique majeure de santé publique : l’objectif n’est plus d’atteindre un âge très avancé, mais plutôt de réussir son vieillissement ! Et l’activité physique a un rôle prépondérant dans cette réussite ! En effet, avec l’avancée en âge peuvent survenir des désagréments de santé, physique et psychologique. Outre les troubles chroniques (diabète, hypertension, excès de cholestérol) et les baisses de moral associées, nous faisons face à une perte de force, d’endurance et d’équilibre, à l’ostéoporose et à la sarcopénie. La perte d’autonomie qui en découle est la principale crainte des Français (tous âges confondus) liée au vieillissement. Pourtant, des solutions simples existent pour stopper cette spirale négative ! L’activité physique est un outil de prévention – elle ralentit les effets du vieillissement et protège des conséquences de la sédentarité –, et un outil de traitement : il n’est jamais trop tard pour se mettre à bouger, dans la mesure de ses capacités, et améliorer sa qualité de vie et sa santé ! Avec des explications claires, des astuces pour modifier en douceur ses habitudes de vie et des exercices accessibles à faire chez soi, ce livre est un guide complet pour envisager un vieillissement serein et rester actif et indépendant pendant longtemps.

Oogenesis - the process by which female germ cells develop into mature eggs, or ova - is a complex process involving many important elements of developmental and cellular biology: from cell-cell interactions, complex signalling cascades, specialized cell cycles and cytoskeleton organization. Oocytes from various species (including clam, starfish, xenopus and mouse) are excellent model systems to study the biochemistry of cell division with important implications for basic and clinical research. This book describes the entire process of oogenesis in chronological order with contributions from leading international researchers and chapters covering medical and ethical considerations in oogenic biology. Topics include sex determination and gonadal development, control of meiotic chromosome pairing and homologous recombination, control of meiotic divisions and the remodelling of the oocyte into a totipotent zygote as well as medically-assisted reproduction. This volume is an essential resource for all students, researchers and clinicians in developmental and reproductive biology. Key features: Reaches beyond the study of simply meiosis to cover all aspects of oogenesis Synthesizes recent advances in the field, drawing on studies from different model species Chapter sequence designed to follow the time line in vivo Written by an international panel of expert researchers

In sub-Saharan Africa, older people make up a relatively small fraction of the total population and are supported primarily by family and other kinship networks. They have traditionally been viewed as repositories of information and wisdom, and are critical pillars of the community but as the HIV/AIDS pandemic destroys family systems, the elderly increasingly have to deal with the loss of their own support while absorbing the additional responsibilities of caring for their orphaned grandchildren. Aging in Sub-Saharan Africa explores ways to promote U.S. research interests and to augment the sub-Saharan governments' capacity to address the many challenges posed by population aging. Five major themes are explored in the book such as the need for a basic definition of "older person," the need for national governments to invest more in basic research and the coordination of data collection across countries, and the need for improved dialogue between local researchers and policy makers. This book makes three major recommendations: 1) the development of a research agenda 2) enhancing research opportunity and implementation and 3) the translation of research findings.

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].

“Simplexity, as I understand it, is the range of solutions living organisms have found, despite the complexity of natural processes, to enable the brain to prepare an action and plan for the consequences of it. These solutions are simplifying principles that enable the processing of information or situations, by taking into account past experience and anticipating the future. They are neither caricatures, shortcuts, or summaries. They are new ways of asking questions, sometimes at the cost of occasional detours, in order to achieve faster, more elegant, more effective actions.” A. B. As Alain Berthoz demonstrates in this profoundly original book, simplicity is never easy; it requires suppressing, selecting, connecting, thinking, in order to then act in the best way possible. And what if we, in turn, are inspired by the living world to process the complexity that surrounds us? Alain Berthoz is professor at the Collège de France where he is co-director of the Laboratoire de physiologie de la perception et de l’action. [Laboratory for the physiology of perception and action]. He is a member of the French Academy of Sciences, and is the author of Le Sens du mouvement [The Brain's Sense of Movement] and La Décision [Emotion and Reason].
