Book Description
There has been a lot of debate concerning the nature of the molecular mechanism that produces filament sliding and muscle shortening. This book presents the different kinds of structural and mechanical evidence in favour of the swinging of myosin heads on actin during the contractile cycle.

Book Description
This book describes the evolution of ideas relating to the mechanism of muscular contraction since the discovery of sliding filaments in 1954. An amazing variety of experimental techniques have been employed to investigate the mechanism of muscular contraction and relaxation. Some background of these various techniques is presented in order to gain a fuller appreciation of their strengths and weaknesses. Controversies in the muscle field are discussed along with some missed opportunities and false trails. The pathway to ATP and the high energy phosphate bond will be discussed, as well as the discovery of myosin, contraction coupling and the emergence of cell and molecular biology in the muscle field. Numerous figures from original papers are also included for readers to see the data that led to important conclusions. This book is published on behalf of the American Physiological Society by Springer. Access to APS books published with Springer is free to APS members.

Book Description
Molecular Control Mechanisms in Striated Muscle Contraction addresses the molecular mechanisms by which contraction of heart and skeletal muscles is regulated, as well as the modulation of these mechanisms by important (patho)physiological variables such as ionic composition of the myoplasm and phosphorylations of contractile and regulatory proteins. For the novice, this volume includes chapters that summarize current understanding of excitation-contraction coupling in striated muscles, as well as the compositions and structures myofibrillar thick and thin filaments. For the expert, this volume presents detailed pictures of current understanding of the mechanisms underlying the CA2+ regulation of contraction in heart and skeletal muscles and discusses important directions for future investigation.

Book Description
Striated muscle is the most common muscle type in the vertebrate body. This book describes in molecular terms the components and intracellular events responsible for the contraction and relaxation of striated muscle. The topic is introduced with a discussion of motile systems occurring throughout the biological world and their relation to the highly specialised contractile system of muscle. Professor Perry then goes on to discuss the mechanochemical process and the regulatory roles of calcium, I filament proteins and phosphorylation. The book ends with an examination of the role of dystrophin and its implications in Duchenne muscular dystrophy, the most common form of muscle disease. Molecular Mechanisms in Striated Muscle will provide an important source of information and current theory for researchers and postgraduate students in muscle physiology, biochemistry and medicine.

Book Description
This volume presents the proceedings of a muscle symposium, which was supported by the grant from the Fujihara Foundation of Science to be held as the Fourth Fujihara Seminar on October 28 -November 1, 2002, at Hakone, Japan. The Fujihara Seminar covers all fields of natural science, while only one proposal is granted every year. It is therefore a great honor for me to be able to organize this meeting. Before this symposium, I have organized muscle symposia five times, and published the proceedings: " Cross-bridge Mechanism in Muscle Contraction (University of Tokyo Press, 1978), "Contractile Mechanisms in Muscle" (plenum, 1984); "Molecular Mechanisms of Muscle Contraction" (plenum, 1988); "Mechanism of MyofIlament Sliding in Muscle contraction" (plenum, 1993); "Mechanisms of Work Production and Work Absorption in Muscle" (plenum, 1998). As with these proceedings, this volume contains records of discussions made not only after each presentation but also during the periods of General Discussion, in order that general readers may properly evaluate each presentation and the up-to-date situation of this research field. It was my great pleasure to have Dr. Hugh Huxley, a principal discoverer of the sliding fIlament mechanism in muscle contraction, in this meeting. On my request, Dr. Huxley kindly gave a special lecture on his monumental discovery of myofIlament-lattice structure by X-ray diffraction of living skeletal muscle. I hope general readers to learn how a breakthrough in a specific research field can be achieved.

Book Description
Molecular Motors and Muscle is the second of a three-part series on Fibrous Proteins. The books are based on a very successful workshop in Alpbach, Austria on the general topic of Fibrous Proteins that gave rise to the award-winning issue of Journal of Structural Biology. There are two major types of protein: Globular proteins which are often enzymes which speed up biochemical reactions and Fibrous proteins which often have more structural roles but can also have dynamic properties. Fibrous proteins are usually either elongated molecules which pack together to form long filaments, as in the case of the intermediate filaments in our hair and skin and as in collagen fibrils in tendons and bones or they are globular proteins which aggregate linearly to form long filaments, such as actin filaments or microtubules. Fibrous proteins act as molecular scaffolds in cells, they can be involved in transport of cell organelles or even on a visible scale as in our muscles. They provide the supporting structures of our skeletons, bones, tendons, cartilage, and skin. They define the mechanical properties of our internal hollow organs such as the intestines, heart, and blood vessels. They are vital for life and represent a fascinating subset of the proteome.

Book Description
Thoroughly researched using experimentation and re-examination of all previously published evidence, Molecular and Physiological Mechanisms of Muscle Contraction is a carefully crafted treatise and revision of previous conceptions of muscle contraction. It presents detailed descriptions of new, previously unpublished data and hybrids recent findings with the standard Huxley model. This book demonstrates that traditional concepts cannot fully explain contraction and builds upon previous work. It identifies flaws in the reasoning initially used to explain some results as well as alternative interpretations accounting for inconsistencies. In response to previous bodies of inconsistent or conflicting theories and data, the book synthesizes research based on the Huxley model with more recent experimental and laboratory findings to define a new model. The new model this book proposes is not a replacement for the standard Huxley model of muscle contraction, but a modification based on recent research and synthesized with pre-existing data and conceptions. It reconciles new data with prior information that is contradictory or not entirely explicable in proposing a new integrated and more complete model of muscle contraction.

Book Description
`In contrast to common practice, we have always tried to include as many discussions held at the meeting in our proceedings as possible, so as to enable readers to properly evaluate each paper presented, as well as to learn of future prospects in this field of research. Although the policy of including discussions occasions a long publication delay, we believe that it is worth repeating in our future publication, as we have met a number of young investigators fascinated by the discussions in our proceedings.... In the concluding remarks in this volume, Dr. Hugh E. Huxley, a principal architect of the sliding filament mechanism of muscle contraction, states that the molecular mechanism of myofilament sliding remains mysterious to all of us. We hope that this volume will stimulate muscle investigators to design and perform novel experiments to clarify the mysteries in muscle contraction.' Haruo Sugi and Gerald H. Pollack, excerpted from the Preface.
