Lymphocyte Signal Transduction
Signal transduction through leukocyte receptors involves a variety of signaling molecules including kinases, phosphatases, adaptor proteins, small GTPases GTP exchange factors, membrane phospholipids as well as others. These signal transducers, regulated by inter- and intra-molecular interactions, as well as by various post-translational modifications, lead to the activation of transcription factors that mediate cellular differentiation and growth, effector cell functions, and apoptotic cell death. Several investigators from various parts of the world convened at the 3rd Lymphocyte Signal Transduction Workshop in Crete, Greece from May 27 to June 1, 2005 to discuss their most recent findings in leukocyte signaling. This volume represents a collection of topics discussed during the conference.

Les douleurs abdominales en questions : Rôle physiopathologique de la sensibilité viscérale = Abdominal pain in question : The pathophysiological role of visceral sensitivity
The gut-brain axis refers to the network of nerve pathways that connect the myenteric plexus, the veritable "gut brain," to the central nervous system. Nearly 80% of these neurons are sensory neurons, and the afferent pathways that transmit information from the digestive tract to the central nervous system play a crucial role in the physiological regulation of digestive functions, as well as in certain pathological conditions. A large majority of these sensations remain unconscious and give rise to reflex responses. Only those requiring a conscious response reach the level of awareness in a normal state (hunger, thirst, the urge to defecate). In pathological situations, the same is true for painful sensations of digestive origin. Functional bowel disorders are a frequent reason for consultation. Their pathophysiology is now based on a model integrating the various etiological factors around the brain-gut axis. These patients frequently present with visceral hypersensitivity, which manifests as an increased perception of digestive sensations, notably the onset of pain in response to stimuli that are not painful in normal subjects. Recognizing the role of visceral hypersensitivity has made it possible to explain the mechanism of action of medications used to treat functional bowel disorders and paves the way for the development of new molecules acting on digestive afferents. In this book, we will describe the anatomical and physiological basis for understanding the concept of visceral sensitivity and the role of digestive afferents in the pathophysiology of acute and chronic abdominal pain, particularly irritable bowel syndrome.
Left-right asymmetry in vertebrate development
A host of studies has unravelled the involvement of many genes in the left right patterning pathway. Based on this knowledge the genetic basis of human laterality defects are beginning to be revealed. It is a major challenge now to understand how all these genes control left right development as well as the complex set of interactions established between them.
Le dépistage du cancer du sein : un enjeu de santé publique = Breast cancer screening: a public health issue
Fifteen years after the first experiments, the breast cancer screening program was rolled out in France in 2004. It is aimed at more than eight million women aged 50 to 74. Public health action on such a scale is exemplary in Europe and especially in France where the health system is not centralized. The new edition of this book takes stock of the current state of the program and its initial results. It updates technical and radiological aspects, assessment indicators, communication and forensic problems and finally the progress of foreign programs. The history of the French program is detailed from the 1990s until 2006, with the publication of the latest version of the specifications by the Directorate General of Health. The short and medium term objectives are re-specified: to increase the participation of women, to retain them and to further improve the quality of practices. The challenge is to combine the performance of screening and therapeutic management to finally achieve a clear reduction in mortality, which has remained stable for twenty years.

Lake Taihu, China : Dynamics and Environmental Change
There are many shallow lakes in the world. Many of them play an important socio-economic role as contributors to the drinking water supply, in flood attenuation, fisheries and recreation activities. Because of the current anthropogenic changes in the environment, such lakes rapidly respond to eutrophication and swamping. It is often hard to address these issues because many changes in the ecosystems of shallow lakes are associated with little studied physical processes. This interaction between the aquatic biota and the physical and chemical environment increases the complexity of shallow lake ecosystems. Lake Taihu, located in the delta of Yangtze River, is a typical large, shallow eutrophic lake with area of 2338 km2 and maximum depth of less than 3m . This book provides basic data on various aspects of this lake and summarizes research work on the interaction between its ecology and physical limnology. It will be a reference for teachers and students of freshwater ecology and biology, the aquatic environment in general, and, most strikingly, for all those interested in physical limnology.
La phytocosmétologie thérapeutique = Herapeutic phytocosmetology
Deals with restorative cosmetology. This is understood through the eyes of the doctor specializing in phytotherapy. Three main aspects are discussed: the diagnosis of disturbance of the skin and integuments, external treatment with natural substances, as well as oral treatment (internal treatment). Oral cosmetology has no official recognition, yet the effects of plant extracts on the condition of the skin and integuments are well known. After an introduction to the physiology of the skin, the dosage and the phenomena of skin deterioration, the author discusses different types of treatment depending on the extracts used while explaining their mode of action. This work was written by a doctor, Doctor Paul Goetz, teacher in clinical phytotherapy, and a pharmacist, Doctor Christian Busser, pharmaceutical and scientific advisor, doctor in ethnology and ethnopharmacologist.
La disprassia in età evolutiva : Criteri di valutazione ed intervento = Dyspraxia in developmental age : Evaluation criteria and intervention
As clinical and rehabilitation practice shows, children with dyspraxia are unable to plan and organize an action plan; they cannot control what they are doing during an action; therefore, they cannot do something, but we could also admit that they cannot yet do something; that is, they have not yet learned to perform functions. Functions and actions, however, can be learned and performed with the help of targeted exercises performed consistently. It is, however, essential to recognize the difficulties children with dyspraxia face when faced with new, unusual tasks. The author proposes an assessment and intervention model that takes into account etiological and neuropsychological hypotheses, emphasizing the need to proceed with an analysis on multiple levels: perceptual, motor, and representational. Particular importance is given to early diagnosis and intervention to define and implement appropriate treatment plans. The work concludes with the analysis and description of clinical cases related to some specific forms of dyspraxia: verbal dyspraxia and dysgraphia.
L’esprit de l’aiguille : L’apport du Yi Jing à la pratique de l’acupuncture = The Spirit of the Needle: The contribution of the Yi Jing to the practice of acupuncture
Acupuncture deciphers and heals human beings in all their mutations. The symbolism of Yi Jing joins the humanism of this Traditional Medicine for a dynamic reading of the changes and transformations at work in human beings. The double reflection generates a global vision of the human being and the approach to patients is changed. After an approach to the state of mind, encountered in these two fields, the author sets out to find the oldest roots of the notions of Yin and Yang. This allows him to identify the main strengths of the constitution of a human being and to deepen its symbolic construction. Three fields of application of this approach are then studied. The Extraordinary Meridians are viewed from a descriptive and behavioral perspective, which makes them extremely lively and familiar. Luo points, human being's relationship points with Reality, are also considered on a practical level using a symbolic reading of the links of Heaven, Earth and Man. Many examples shed light on these aspects. The last application is a detailed and comprehensive presentation of the fundamental and symbolic functions of the twelve main meridians through the hexagrams which correspond to their ancient Shu points. This original book is intended for any practitioner of traditional Chinese medicine curious to broaden their field of investigation. Dr M. Vinogradoff has been practicing acupuncture for 25 years. He is a member of the French Acupuncture Association, the French Acupuncture College and the Ricci Institute. After having published the complete translation of Yi Jing, in 2006 he published a novel, the action of which is set in Ancient China.
