"Oxidative stress" is used as the generic term describing the involve ment of reactive oxygen species in various human diseases. The scope of such a topic is becoming increasingly wide. The recent interest in radicals such as nitric oxide and the discovery of new mechanisms such as the effect of free radicals on redox sensitive proteins and genes are enlarging our understanding of the physiological role of free radicals. Oxidative stress is involved in numerous pathological. processes such as ageing, respiratory or cardiovascular diseases, cancer, neurological pathologies such as dementia or Parkinson's disease. It still remains difficult, however, to demonstrate by chemical measurement the in vivo production of free radicals and even more to realise their speciation. Therefore, the development of new tools and indicators is engrossing many researchers working in this field. Reliable indicators are abso lutely necessary not only to monitor the evolution of oxidative stress in patients but also to evaluate the efficiency of new antioxidant treat ments. The French Free radical club of Grenoble, the CERLIB has been involved for many years in the organisation of international training programs on methodology, in order to provide both theoretical and practical help to researchers from various countries. Such training sessions have been highly successful and participants value the oppor tunity to learn reliable techniques. This positive echo explains why the researchers of CERLIB decided, with the help of Prof. Dr. B. Kalyanaraman, to publish selected techniques on free radical re search.

We are always hearing about the Next Big Thing. Whether it is a new iPhone or the New World, the freshest and newest inventions, discoveries, and fads always loom large in the public mind. The impact that everyone thinks these "next big things" will have is often more important than the actual impact it generates. After all, if it fails, it will be almost immediately forgotten. The Next Big Thing searches through 3,000 years of Western culture to find the colorful and key steps (and missteps) that led us to where we are today.

The Frontiers Research Topic entitled "Neuromuscular Training and Adaptations in Youth Athletes" contains one editorial and 22 articles in the form of original work, narrative and systematic reviews and meta-analyses. From a performance and health-related standpoint, neuromuscular training stimulates young athletes' physical development and it builds a strong foundation for later success as an elite athlete. The 22 articles provide current scientific knowledge on the effectiveness of neuromuscular training in young athletes.

The lung receives the entire cardiac output from the right heart and must load oxygen onto and unload carbon dioxide from perfusing blood in the correct amounts to meet the metabolic needs of the body. It does so through the process of passive diffusion. Effective diffusion is accomplished by intricate parallel structures of airways and blood vessels designed to bring ventilation and perfusion together in an appropriate ratio in the same place and at the same time. Gas exchange is determined by the ventilation-perfusion ratio in each of the gas exchange units of the lung. In the normal lung ventilation and perfusion are well matched, and the ventilation-perfusion ratio is remarkably uniform among lung units, such that the partial pressure of oxygen in the blood leaving the pulmonary capillaries is less than 10 Torr lower than that in the alveolar space. In disease, the disruption to ventilation-perfusion matching and to diffusional transport may result in inefficient gas exchange and arterial hypoxemia. This volume covers the basics of pulmonary gas exchange, providing a central understanding of the processes involved, the interactions between the components upon which gas exchange depends, and basic equations of the process.

Poetics of the Iconotext makes available for the first time in English the theories of the respected French text/image specialist, Professor Liliane Louvel. A consolidation of the most significant theoretical materials of Louvel's two acclaimed books, L'Oeil du Texte: Texte et image dans la littérature anglophone and Texte/Image: Images à lire, textes à voir, this newly conceived work introduces English readers to the most current thinking in French text/image theory and visual studies. Focusing on the full spectrum of text/image relations, from medieval illuminated manuscripts to digital books, Louvel begins by introducing key terms and situating her work in the context of significant debates in text/image studies. Part II introduces Louvel's s typology of pictorial saturation through which she establishes a continuum along which to measure the effect of the most figurative to the most literal images upon writerly and readerly textual 'spaces.' Part III adopts a phenomenological approach towards the reading-viewing experience as expressed in conceptual categories that include the trace, focal range, synesthesia, and rhythm and speed. The result is a provocative interplay of the categorical and the subjective that invites readers to think at once more precisely and more inventively about texts, images, and the intersections between the two.

This essential new volume in the Encyclopaedia of Sports Medicine series, published under the auspices of the International Olympic Committee, provides a thorough overview of the unique physiologic characteristics, responsiveness to training, and possible health hazards involved in the training, coaching, and medical care of young athletes. Intense involvement in competitive sports often begins during childhood. During adolescence, many athletes reach their peak performance and some may participate in World Championships and Olympic Games at a relatively young age. The Young Athlete presents the available information relevant to exercise and training in youth, reviewed and summarized by authors who are recognized as leaders in their respective fields. The Young Athlete is subdivided into seven parts covering: the physiologic bases of physical performance in view of growth and development; trainability and the consequences of a high level of physical activity during childhood and adolescence for future health; the epidemiology of injuries, their prevention, treatment, and rehabilitation; non-orthopedic health concerns including the pre-participation examination; psychosocial issues relevant to young athletes; diseases relevant to child and adolescent athletes; the methodology relevant to the assessment of young athletes. This valuable reference summarizes a large database of information from thousands of studies and is especially relevant to sports physicians, pediatricians, general practitioners, physical therapists, dietitians, coaches, students, and researchers in the exercise sciences.

Now in its fully revised and expanded third edition, this comprehensive text represents a compilation of the critical endocrinology topics in the areas of sports medicine, kinesiology and exercise science, written by leading experts in the field. As in previous editions, the focus here is on the critical issues involved in understanding human endocrinology and hormonal workings with regards to physical activity, exercise and sport and how such workings impact the full range of medical conditions, overall health and physiological adaptation. Chapters included discuss the effect of exercise on the HPA axis, the GH-IGF-1 axis, thyroid function, diabetes, and the male and female reproductive systems, among other topics. Additional chapters present the current evidence on circadian endocrine physiology, exercise in older adults, exercise and hormone regulation in weight control, and the effects of overtraining in sports. Chapters brand new to this edition present the role of hormones in muscle hypertrophy, the effect of exercise on hormones in metabolic syndrome patients, how exercise impacts appetite-regulating hormones in clinical populations, and the relative energy deficiency in sport (RED-S) condition.
