Depuis les premières descriptions cliniques datant de la fin du XIXe siècle, montrant l’intérêt médical relativement récent pour l’anxiété, les symptômes anxieux et les troubles anxieux, les concepts ont considérablement évolué au cours du XXe siècle pour aboutir aux classifications syndromiques en vigueur dans la nosographie actuelle. Pourtant, un certain nombre de questions demeurent, par exemple sur l’existence d’un continuum entre une anxiété normale et adaptative et une anxiété pathologique, la nature de la réactivité émotionnelle dans les troubles anxieux par rapport à celle décrite dans les troubles bipolaires, etc... La première partie d’ouvrage présente les diverses approches actuelles pour comprendre les troubles anxieux : modèles émotionnels, approche évolutionniste, psychodynamique, théorie de l’attachement, génétique, neurobiologie, neuropsychologie, électrophysiologie et neuro-imagerie. Sont ensuite exposés les différents troubles anxieux (attaque de panique, phobie sociale, trouble anxieux généralisé, hypocondrie, état de stress post-traumatique, TOC, etc.) et les associations co-morbides (dépression, conduites suicidaires, troubles bipolaires, addictions, etc...). Réunissant plus d’une quarantaine de spécialistes reconnus, riche d’une trentaine tableaux et schémas explicatifs et d’un index détaillé, cet ouvrage offre un état des connaissances et des recherches sur les troubles anxieux.

A large part of the world’s coastlines consists of sandy beaches and dunes that may undergo dramatic changes during storms. Extreme storm events in some cases dominate the erosion history of the coastline and may have dramatic impacts on densely populated coastal areas. Policy, research and historical background are essential elements that need to be interconnected for effective coastal planning and management. This book discusses this framework, with Chapter 1 providing an insight into policy settings and science-policy interactions in the area of coastal risks related to storms and flooding, and integrated coastal zone management. This is followed by a review of the current understanding of the processes generating extreme coastal events, the morphological evolution of coastlines during and after the events, and the methods for monitoring the process as it occurs or for post-event appraisal. The final chapter discusses the importance of historical approaches regarding coastal threats, taking the Xynthia storm as an example.
Annotation. The subject of this book is stem cell research and regenerative medicine. Stem cells are undifferentiated cells that have the ability to differentiate into different lineages of the body. Stem cells carry tremendous potential for the treatment of a broad range of disease and injuries. Stem cells exist in embryonic, foetal, and adult tissues, including the adult central nervous system. This book aims at, in depth, the recent developments in stem cell research and regenerative medicine. Though this book encompasses all the fields of stem cell research and regenerative medicine, it emphasises embryonic and adult stem cells.

Having appeared in the 1930s in Montreal, standardised neuropsychological evaluation has become an essential tool in the clinical diagnosis and evaluation of surgical epileptic patients. Nevertheless, despite great progress over the last 20 to 30 years in the diagnosis and medical treatment of epilepsy, clinical neuropsychology still remains largely associated with surgical epilepsy, particularly surgery of the temporal lobe. Clinical neurology has still not managed to clear a way in the daily practice with patients with all types of epilepsy despite significant advances in cognitive neuroscience and a large number of clinical studies on epilepsy and cognition. How is it that there are only rarely major advances in the field of clinical neuropsychology? It has long been time for this question to be asked, and for an attempt to be made to bring about changes. This was the aim of the Toronto workshop and the result of this book. Every approach was debated, providing important elements to reflect on and allowing a great forum for exchanges. This book includes the communications from the main participants and comments from some others on specific subjects.
We heartily recommend this book to all readers who wish to gain a better understanding of nanostructured carbon materials surface properties and used in catalysis." An-Hui Lu, ChemCatChem There is great interest in using nanostructured carbon materials in catalysis, either as supports for immobilizing active species or as metal-free catalysts due to their unique structural, thermal, chemical, electronic and mechanical properties, and tailorable surface chemistry. This book looks at the structure and properties of different doped and undoped nanocarbons including graphene; fullerenes; nanodiamonds; carbon nanotubes and nanofibers; their synthesis and modification to produce catalysts. Special attention is paid to adsorption, as it impacts the application of these materials in various industrially relevant catalytic reactions discussed herein, in addition to photocatalysis and electrocatalysis. Written by leading experts in the area, this is the first book to provide a comprehensive view of the subject for the catalysis community.
This new edition of the book series dedicated to “Progress in Epileptic Disorders” is the result of a recently held unique gathering of international experts that debated on the prognostic and therapeutic issues raised by the management of first unprovoked seizures and of newly diagnosed epilepsy. Current knowledge on natural evolution of a first seizure, the role of co-morbid conditions, the impact of immediate versus delayed treatment and recent guidelines are thoroughly addressed. The new ideas and suggestions that emerge from this book offer challenging perspectives for both patient care and clinical as well as fundamental research. The first section of the book includes an up to date review of epidemiological data, encompassing the natural evolution of single unprovoked seizures, risk factors for recurrent seizures, and the potential for comorbid conditions such as depression, migraine, ADHD, and dysimmune metabolic disorders to promote the development of epilepsy. The impact of febrile convulsions on long-term brain hyperexcitability is also discussed. The second section concentrates on therapeutic issues, concerning the management of single unprovoked seizures and newly diagnosed epilepsy. These include the impact of immediate versus deferred treatment and the choice of the most appropriate antiepileptic drug therapy. Several methodological issues are addressed in parallel with the chapters, providing new insights into domains, such as the representativeness of the patient population in the studies under consideration, as well as the limitations and pitfalls of most randomised controlled trials. The value of these trials in the development of treatment guidelines is also discussed.
