Book Synopsis Molecular and Physiological Mechanisms of Muscle Contraction by : Jean Emile Morel
Download or read book Molecular and Physiological Mechanisms of Muscle Contraction written by Jean Emile Morel and published by CRC Press. This book was released on 2015-11-05 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 It presents detailed descriptions of new, previously unpublished data and hybrids recent findings with the standard Huxley model.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.

This book was released on 2012-12-06 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Muscle Contraction and Cell Motility by : H. Sugi
Download or read book Muscle Contraction and Cell Motility written by H. Sugi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume intends to provide a comprehensive overview on the mecha nisms of muscle contraction and non-muscle cell motility at the molecu lar and cellular level, not only for investigators in these fields but also for general readers interested in these topics. A most attractive feature of various living organisms in the animal and plant kingdoms is their ability to move. In spite of a great diversity in the structure and function of various motile systems, it has frequently been assumed since the nineteenth century that all kinds of "motility" are essentially the same. Based on this assumption, some investigators in the nineteenth century thought that the mechanisms of motility could better be studied on primitive non-muscle motile systems such as amoeboid movement, rath er than on highly specialized muscle cells. Contrary to their expectation, however, the basic mechanisms of motility have been revealed solely by investigations on vertebrate skeletal muscles, since a monumental discovery of Szent-Gyorgyi and his coworkers in the early 1940s that muscle contraction results from the interaction between two different contractile proteins, actin and myosin, coupled with ATP hydrolysis.
Book Synopsis The Sliding-Filament Theory of Muscle Contraction by : David Aitchison Smith
Download or read book The Sliding-Filament Theory of Muscle Contraction written by David Aitchison Smith and published by Springer. This book was released on 2019-02-05 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the molecular mechanism of muscle contraction started with the discovery that striated muscle is composed of interdigitating filaments which slide against each other. Sliding filaments and the working-stroke mechanism provide the framework for individual myosin motors to act in parallel, generating tension and loaded shortening with an efficient use of chemical energy. Our knowledge of this exquisitely structured molecular machine has exploded in the last four decades, thanks to a bewildering array of techniques for studying intact muscle, muscle fibres, myofibrils and single myosin molecules. After reviewing the mechanical and biochemical background, this monograph shows how old and new experimental discoveries can be modelled, interpreted and incorporated into a coherent mathematical theory of contractility at the molecular level. The theory is applied to steady-state and transient phenomena in muscle fibres, wing-beat oscillations in insect flight muscle, motility assays and single-molecule experiments with optical trapping. Such a synthesis addresses major issues, most notably whether a single myosin motor is driven by a working stroke or a ratchet mechanism, how the working stroke is coupled to phosphate release, and whether one cycle of attachment is driven by the hydrolysis of one molecule of ATP. Ways in which the theory can be extended are explored in appendices. A separate theory is required for the cooperative regulation of muscle by calcium via tropomyosin and troponin on actin filaments. The book reviews the evolution of models for actin-based regulation, culminating in a model motivated by cryo-EM studies where tropomyosin protomers are linked to form a continuous flexible chain. It also explores muscle behaviour as a function of calcium level, including emergent phenomena such as spontaneous oscillatory contractions and direct myosin regulation by its regulatory light chains. Contraction models can be extended to all levels of calcium-activation by embedding them in a cooperative theory of thin-filament regulation, and a method for achieving this grand synthesis is proposed. Dr. David Aitchison Smith is a theoretical physicist with thirty years of research experience in modelling muscle contractility, in collaboration with experimental groups in different laboratories.

Book Synopsis Molecular Mechanisms in Striated Muscle by : S. V. Perry
Download or read book Molecular Mechanisms in Striated Muscle written by S. V. Perry and published by Cambridge University Press. This book was released on 1996-09-13 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Mechanisms of Work Production and Work Absorption in Muscle by : Haruo Sugi
Download or read book Mechanisms of Work Production and Work Absorption in Muscle written by Haruo Sugi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: `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.

Book Synopsis Muscular Contraction by : Robert Malcolm Simmons
Download or read book Muscular Contraction written by Robert Malcolm Simmons and published by Cambridge University Press. This book was released on 1992-06-26 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composed of a set of chapters contributed by past and present collaborators of the Nobel laureate Sir Andrew Huxley, this book covers the areas of muscle research to which Huxley made major contributions. The purpose of the book is to discuss the way that muscles work, asking questions at a fundamental level about the molecular basis of muscle tone production and muscle contraction. The majority of the chapters are concerned with muscle physiology and the relation between structure and function. The process of activation of muscles is discussed, along with the mechanism of contraction itself. Although most of the book deals with vertebrate skeletal muscle, several chapters cover cardiac muscle. Also featured are two chapters discussing Sir Andrew's achievements in both nerve and muscle physiology.

Available in PDF, EPUB and Kindle. Book excerpt: Prior to the emergence of the sliding filament model, contraction theories had been in abundance. In the absence of the kinds of structural and biochemical information available today, it has been a simple matter to speculate about the possible ways in which tension generation and shortening might occur. The advent of the sliding filament model had an immediate impact on these theories; within several years they fell by the wayside, and attention was redirected towards mechanisms by which the filaments might be driven to slide by one another. In terms of identifying the driving mechanism, the pivotal observa tion was the electron micrographic indentification of cross-bridges extending from the thick filaments. It was quite naturally assumed that such bridges, which had the ability to split ATP, were the molecular motors, i.e., that they were the sites of mechanochemical transduction. Out of this presumption grew the cross-bridge model. in which filament sliding is presumed to be driven by the cyclic interaction of cross-bridges with complementary actin sites located along the thin filaments.
Book Synopsis Fibrous Proteins: Muscle and Molecular Motors by : John M. Squire
Download or read book Fibrous Proteins: Muscle and Molecular Motors written by John M. Squire and published by Gulf Professional Publishing. This book was released on 2005-08-29 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
