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 Muscle Homeostasis and Regeneration by : Antonio Musarò
Download or read book Muscle Homeostasis and Regeneration written by Antonio Musarò and published by MDPI. This book was released on 2020-11-20 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a collection of original research and review articles addressing the intriguing field of the cellular and molecular players involved in muscle homeostasis and regeneration. One of the most ambitious aspirations of modern medical science is the possibility of regenerating any damaged part of the body, including skeletal muscle. This desire has prompted clinicians and researchers to search for innovative technologies aimed at replacing organs and tissues that are compromised. In this context, the papers, collected in this book, addressing a specific aspects of muscle homeostasis and regeneration under physiopathologic conditions, will help us to better understand the underlying mechanisms of muscle healing and will help to design more appropriate therapeutic approaches to improve muscle regeneration and to counteract muscle diseases.

Book Synopsis Skeletal Muscle Circulation by : Ronald J. Korthuis
Download or read book Skeletal Muscle Circulation written by Ronald J. Korthuis and published by Morgan & Claypool Publishers. This book was released on 2011 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this treatise is to summarize the current understanding of the mechanisms for blood flow control to skeletal muscle under resting conditions, how perfusion is elevated (exercise hyperemia) to meet the increased demand for oxygen and other substrates during exercise, mechanisms underlying the beneficial effects of regular physical activity on cardiovascular health, the regulation of transcapillary fluid filtration and protein flux across the microvascular exchange vessels, and the role of changes in the skeletal muscle circulation in pathologic states. Skeletal muscle is unique among organs in that its blood flow can change over a remarkably large range. Compared to blood flow at rest, muscle blood flow can increase by more than 20-fold on average during intense exercise, while perfusion of certain individual white muscles or portions of those muscles can increase by as much as 80-fold. This is compared to maximal increases of 4- to 6-fold in the coronary circulation during exercise. These increases in muscle perfusion are required to meet the enormous demands for oxygen and nutrients by the active muscles. Because of its large mass and the fact that skeletal muscles receive 25% of the cardiac output at rest, sympathetically mediated vasoconstriction in vessels supplying this tissue allows central hemodynamic variables (e.g., blood pressure) to be spared during stresses such as hypovolemic shock. Sympathetic vasoconstriction in skeletal muscle in such pathologic conditions also effectively shunts blood flow away from muscles to tissues that are more sensitive to reductions in their blood supply that might otherwise occur. Again, because of its large mass and percentage of cardiac output directed to skeletal muscle, alterations in blood vessel structure and function with chronic disease (e.g., hypertension) contribute significantly to the pathology of such disorders. Alterations in skeletal muscle vascular resistance and/or in the exchange properties of this vascular bed also modify transcapillary fluid filtration and solute movement across the microvascular barrier to influence muscle function and contribute to disease pathology. Finally, it is clear that exercise training induces an adaptive transformation to a protected phenotype in the vasculature supplying skeletal muscle and other tissues to promote overall cardiovascular health.

Book Synopsis Molecular and Cellular Aspects of Muscle Contraction by : Haruo Sugi
Download or read book Molecular and Cellular Aspects of Muscle Contraction written by Haruo Sugi and published by Springer Science & Business Media. 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.

Download or read book Molecular Mechanism of Muscle Contraction written by Haruo Sugi and published by Springer. This book was released on 1988-05 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now widely recognized that fundamental progress in science is made not in a continuous manner but in a stepwise manner. In the field of the molecular mechanism of contraction in striated muscle, the stepwise progress was achieved by three great investigators in 1940's and 1950's. In the early 1940's, Albert Szent-Gyorgyi and his associates showed biochemically that muscle contraction is essentially an interaction between actin and myosin coupled with ATP hydrolysis. Then, in the 1950's, Hugh E. Huxley together with Jean Hanson demonstrated that striated muscle is composed of a hexagonal lattice of two kinds of interdigtating myofilaments consisting of action and myosin respectively, and made a monumental discovery that muscle contraction results from the relative sliding between the actin and myosin filaments. Andrew F. Huxley, who also participated in the discovery of the sliding filament mechanism of muscle contraction was attributed to the attachment-detachment cycle between the cross-bridges extending from the myosin filament and the complementary sites on the actin filament. After the above stepwise progress, however, muscle research appears to have entered into a period of so-called 'normal science' where detailed knowledge has been accumulating around the well established 'central dogmas' but without fundamental progress. More specifically, most experiments on muscle contraction mechanisms have been designed, carried out and interpreted on the basis of the Huxley's 1957 and the Huxley-Simmons' 1971 contraction models, as well as the kinetic scheme of actomyosin ATPase; but the molecular mechanism of contraction still remains to be a matter for debate and speculation. For further fundamental progress in this field of research, we feel it necessary to reconsider the validity of these dogmas and to interpret the results more freely. In 1978, one of us (H.S.) organized a symposium in Tokyo based on the above idea, and we published the proceedings under the title of "Cross-bridge Mechanism in Muscle Contraction" (ed. H. Sugi and G.H. Pollack, University of Tokyo Press/University Park Press, 1979). The unusual interest of muscle physiologists in this symposium encouraged us to organize a second symposium on muscle contraction in Seattle in 1982, and proceedings was again published under the title of "Contractile Mechanisms in Muscle" (ed. G.H. Pollack and H. Sugi, Plenum Publishing Corporation, 1984). We were again very much encouraged by the intense interest of the people at the symposium as well as by readers of the proceedings, and became convinced that the symposia of this kind would greatly accelerate the progress in this field. The present symposium was organized by one of us (H.S.) as the third "Cross-bride" symposium. Though most papers are concerned, as in the previous two symposia, with experiments on intact and demembranated muscle fibers and isolated myofibrils, where the three-Dimensional muofilament-lattice structures have been preserved, the results are frequently discussed in connection with the kinetics of actomyosin ATPase, reflecting the recent development of experimental methods connecting physiology and biochemistry. It has also become possible to obtain direct information about the orientation and configuration of the cross-bridges as various stages during muscle contraction.
Book Synopsis Molecular Mechanisms Controlling Skeletal Muscle Mass by : Kunihiro Sakuma

Available in PDF, EPUB and Kindle. Book excerpt: The interplay between multiple signaling pathways regulates the maintenance of skeletal muscle. Under physiological conditions, a network of interconnected signals serves to coordinate hypertrophic and atrophic inputs, culminating in a delicate balance between muscle protein synthesis and proteolysis. Loss of skeletal muscle mass, termed "atrophy," is a diagnostic feature of cachexia such as cancer, heart disease, and chronic obstructive pulmonary disease. Recent studies have further defined the pathways leading to gain and loss of skeletal muscle as well as the signaling events that induce post-injury regeneration. In this review, we summarize the relevant recent literature demonstrating these previously undiscovered mediators governing anabolism and catabolism of skeletal muscle.
