Cold-ion populations and cold-electron populations are extremely difficult to measure in the Earth’s magnetosphere, and their properties, evolutions, and controlling factors are poorly understood. They are sometimes referred to as the “hidden populations”. But they are known to have multiple impacts on the behavior of the global magnetospheric system. These impacts include (a) the reduction of the dayside reconnection rate and consequently the reduction of solar-wind/magnetosphere coupling, (b) alteration of the growth rate and saturation amplitudes of plasma waves resulting in alterations of the energization rates of the radiation belts, (c) changes in plasma-wave properties resulting...
Rapid progress has been made in our understanding of the molecular mechanisms of cell growth and oncogenesis during the past decade. Special attention has been given to the presentation of the frequently neglected close correlation between changes in signal transduction and metabolic pathways during oncogenesis. This book advances the knowledge of mechanisms regulating metabolism and functioning of vitamin A and offers the most recent results of research on the clinical efficiency of retinoids in skin disorders and cancer. The book presents recent findings on the regulation of cell growth in normal and neoplastic tissues by growth factors including hormones, and by the activation and inactiv...
The subject for a volume on the fat-soluble vitamins needs no justification considering the importance of this group of nutrients and the rate of expan sion of our knowledge of its role in cell biology, genetics, and disease. The level of our understanding has clearly moved from knowing what fat soluble vitamins do to how they perform their functions. Hand in hand with a knowledge of their molecular mechanisms of action is the recognition that vitamins are used sparingly, and regeneration processes operate in certain cases to recycle vitamins from their metabolites. We have divided the volume into alphabetical sections beginning with vitamin A and the carotenoids through vitamins D, E, F, and K, and ending with coenzyme Q. The contributors are all acknowledged experts in their particular fields and have made significant contributions to published research results. All have worked assiduously to deliver the product of their labors on a restricted time scale and to provide the most up-to date information on their respective topics. We are truly grateful for their indulgence.

The fifth edition of this well-loved manual for understanding and using Muscle Energy Techniques (METs) presents clear guidelines for their applications, resting on the newest scientific research and embedded in the framework of whole-person health care. It provides a comprehensive, evidence-based how-to guide for applying MET in the treatment of some forms of musculoskeletal dysfunction, to alleviate pain, and support functional movement. Packed with colour illustrations and complemented by more than 50 instructional videos featuring Leon Chaitow demonstrating the techniques described, Muscle Energy Techniques 5e guides the reader through both theory and practice, with an emphasis on eviden...
