Muscle contraction has been the focus of scientific investigation for more than two centuries, and major discoveries have changed the field over the years. Early in the twentieth century, Fenn (1924, 1923) showed that the total energy liberated during a contraction (heat + work) was increased when the muscle was allowed to shorten and perform work. The result implied that chemical reactions during contractions were load-dependent. The observation underlying the "Fenn effect" was taken to a greater extent when Hill (1938) published a pivotal study showing in details the relation between heat production and the amount of muscle shortening, providing investigators with the force-velocity relation for skeletal muscles. Subsequently, two papers paved the way for the current paradigm in the field of muscle contraction. Huxley and Niedergerke (1954), and Huxley and Hanson (1954) showed that the width of the A-bands did not change during muscle stretch or activation. Contraction, previously believed to be caused by shortening of muscle filaments, was associated with sliding of the thick and thin filaments. These studies were followed by the classic paper by Huxley (1957), in which he conceptualized for the first time the cross-bridge theory; filament sliding was driven by the cyclical interactions of myosin heads (cross-bridges) with actin. The original cross-bridge theory has been revised over the years but the basic features have remained mostly intact. It now influences studies performed with molecular motors responsible for tasks as diverse as muscle contraction, cell division and vesicle transport.
In mammals, a robust physiologic system acts to maintain relative constancy of weight. A key element of this system is leptin. The nature of this "brain-somatic" cross talk is as yet poorly understood, but it is likely to have important implications for the pathophysiology and treatment of obesity, diabetes and other metabolic disorders.

Clinical Aspects of Electroporation is the first book intended for clinicians on this extremely important and rapidly developing field.
In nature, biological organisms produce mineralized tissues such as bone, teeth, diatoms, and shells. Biomineralization is the sophisticated process of production of these inorganic minerals by living organisms. Construction of organic-inorganic hybrid materials with controlled mineralization analogous to those produced by nature has recently received much attention because it can aid in understanding the mechanisms of the biomineralization process and development of biomimetic materials processing. The biomineralization ? processes use aqueous solutions at temperatures below 100 C and no toxic intermediates are produced in these systems. From a serious global en- ronmental problem point of view, the development of processes inspired by biomineralization would offer valuable insights into material science and en- neering to reduce energy consumption and environmental impact. One of the most challenging scienti?c problems is to gain greater insight into the mol- ular interactions occurring at the interface between the inorganic mineral and the macromolecular organic matrix. Model systems are often regarded as a straight-forward experimental approach toward biomimetic crystallization. Hierarchical architectures consisting of small building blocks of inorganic cr- tals are often found in biominerals. Studies of nanocrystal self-organization in solution systems would also be helpful for understanding biomineralization. In these volumes, we focus on construction of organic-inorganic hybrid - terials with controlled mineralization inspired by natural biomineralization. In the?rst volume, thereader will ?nd contributionsproviding abasic scopeof the mineralization process in aqueous solution.
The past two decades have seen an explosion in the number of research articles relating to both the physiological and pathological responses evoked by nitric oxide generation.

Francis BACON, in his Novum Organum, Robert BOYLE, in his Skeptical Chemist and Rene DESCARTES, in his Discourse on Method; all of these men were witnesses to the th scientific revolution, which, in the 17 century, began to awaken the western world from a long sleep. In each of these works, the author emphasizes the role of the experimental method in exploring the laws of Nature, that is to say, the way in which an experiment is designed, implemented according to tried and tested te- niques, and used as a basis for drawing conclusions that are based only on results, with their margins of error, taking into account contemporary traditions and prejudices. Two centuries later, Claude BERNARD, in his Introduction to the Study of Experimental Medicine, made a passionate plea for the application of the experimental method when studying the functions of living beings. Twenty-first century Biology, which has been fertilized by highly sophisticated techniques inherited from Physics and Chemistry, blessed with a constantly increasing expertise in the manipulation of the genome, initiated into the mysteries of information techn- ogy, and enriched with the ever-growing fund of basic knowledge, at times appears to have forgotten its roots."
Although phosphorylation of proteins on tyrosine is relatively rare compared to phosphorylation on serine or threonine residues, the past two decades of research into PTP function have led to a great appreciation of the critical role PTPs have in regulating basic cellular processes. Among these important roles is the regulation of cellular signaling pathways related to metabolism. This volume contains chapters which highlight many aspects of PTP function in the context of metabolism. Given the growing obesity and diabetes epidemics in the United States and throughout the world, the desire to identify possible therapeutic targets for treatment of these diseases is a high priority. In many ways, PTPs may be attractive drug targets since they are amenable to targeting with small molecules; however many challenges abound in making PTP inhibitors.
Personalized medicine, which simply means selection of treatment best suited for an individual, involves integration and translation of several new technologies in clinical care of patients. The scope is much broader than indicated by the term genomic medicine because many non-genomic factors are taken into consideration in developing personalized medicine. Basic technologies for personalized medicine, of which molecular diagnostics has the biggest share, are mentioned briefly and appropriate references are given for further information. Commercial aspects are discussed briefly in a chapter and detailed analysis of markets and companies involved in personalized medicine is presented in a special report on this topic. There is increasing interest in personalized medicine. Considerable advances have taken place in molecular biology and biotechnology to make personalized medicine a viable option, but some misconceptions still exist, both in the academic and commercial sectors. There is lack of a suitable source of information that provides both the fundamentals as well as applications of personalized medicine. As the latest version of the first monograph on personalized medicine published in 1998, this volume, Textbook of Personalized Medicine, summarizes the author's efforts during the past decade, as well as reviews selected studies done during this period in a readable format for the physicians and scientists. It is hoped that physicians, pharmacists, scientists and interested lay readers with basic scientific knowledge will find this book useful.
Analytical chemists and materials scientists will find this a useful addition to their armory.
