Book Description
Nous avons étudié au cours du sommeil la survenue d'accidents respiratoires (apnées, hypopnées, désaturations) chez 10 hommes sains (36.7 +/- 1.9 ans, IMC 23.9 kg/m2) et chez 7 hommes obèses asymptomatiques (47.7 +/- 2 ans, IMC 34.7 +/- 1.9 kg/m2). Le nombre d'apnées et d'hypopnées n'était pas différent dans les deux groupes. Chez les obèses, nous avons constaté : des apnées obstructives plus fréquentes, un nombre de désaturations plus grand ( 6 versus 0.6 épisodes par nuit par sujet), et une valeur moyenne de saturation minimale plus faible (89.4% versus 92.4%), notamment dans le sommeil calme. L'obésité représente donc un facteur de risque de perturbations respiratoires nocturnes.

Book Description
“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].

Book Description
The spectrum of sleep-disordered breathing ranges from primary snoring at one end to obstructive sleep apnea and central sleep apnea at the other end. The first chapter in this book provides current state of knowledge about the mechanisms of obstructive sleep apnea and central sleep apnea and reviews emerging therapies for these disorders. Furthermore, sleep apnea usually has multifactorial causes and affects multiple organic systems resulting in increased cardiovascular morbidity, disturbing sleep quality, metabolic balance, glucose and cholesterol levels, arterial hypertension and thus increasing cardiopulmonary and vascular morbidity. The second chapter summarises the main findings in literature and provides a brief and concise differential diagnosis. The authors of the third chapter expose and discuss current evidence of neurosurgical conditions and their role in the genesis and progression of sleep apnea. They emphasise the adequate treatment and future perspectives. The following chapter examine the effect of obstructive sleep apnea syndrome (OSAS) on the eye. Different ophthalmologic disorders are associated with OSAS including floppy eyelid syndrome, retinal vein occlusion, and central serious retinopathy. The last chapter in this book is focused on QT dispersion in patients with obstructive sleep apnea, with increased QT dispersion potentially reflecting disturbed myocardial repolarisation and predisposition to cardiac arrhythmias.

Book Description
What happens – sociologically, linguistically, educationally, politically – when more than one language is in regular use in a community? How do speakers handle these languages simultaneously, and what influence does this language contact have on the languages involved? Although most people in the world use more than one language in everyday life, the approach to the study of language has usually been that monolingualism is the norm. The recent interest in bilingualism and language contact has led to a number of new approaches, based on research in communities in many different parts of the world. This book draws together this diverse research, looking at examples from many different situations, to present the topic in any easily accessible form. Language contact is looked at from four distinct perspectives. The authors consider bilingual societies; bilingual speakers; language use in the bilingual community; finally language itself (do languages change when in contact with each other? Can they borrow rules of grammar, or just words? How can new languages emerge from language contact?). The result is a clear, concise synthesis offering a much-needed overview of this lively area of language study.
