This volume presents the proceedings of a muscle symposium, which was held as the Fourth Fujihara seminar on October 28 - November 1, 2002, at Hakone, Japan. This volume covers all fields of muscle biology, from molecules to humans. This book provides information about recent progress of muscle research as well as the problems that remain to be investigated. This volume will stimulate muscle investigators to design and perform novel experiments to clarify the mysteries in muscle contraction.

Advances in Physiological Sciences, Volume 5: Molecular and Cellular Aspects of Muscle Function covers the proceedings of the 28th International Congress of Physiological Sciences, held in Budapest in 1980 (including the proceedings of the satellite symposium on Membrane Control of Skeletal Muscle Function). The book focuses on the molecular and cellular facets of skeletal muscle function. The selection first offers information on the mechanical properties of cross-bridges and their relation to muscle contraction; molecular basis of functional specialization in muscle as induced by innervation; and electrical properties of crustacean muscle membranes. The text then ponders on contractile protein isoforms in developing muscle; effect of age and exercise on minced gastrocnemius muscle regeneration; and contractile proteins of rat gastrocnemius during its regeneration after mincing. The publication examines the behavior of myosin projections in frog striated muscle during isometric contraction; energetics of contracting muscle and its relation to crossbridge mechanisms; and time course of chemical change and energy production during contraction of frog skeletal muscle. The physiological analysis of human myopathy and adaptation in normal and diseased muscle are also discussed. The selection is a vital source of data for readers interested in the cellular and molecular aspects of muscle function.

This lively book examines recent trends in animal product consumption and diet; reviews industry efforts, policies, and programs aimed at improving the nutritional attributes of animal products; and offers suggestions for further research. In addition, the volume reviews dietary and health recommendations from major health organizations and notes specific target levels for nutrients.

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.

Molecular Aspects of Exercise Biology and Exercise Genomics, the latest volume in the Progress in Molecular Biology and Translational Science series includes a comprehensive summary of the evidence accumulated thus far on the molecular and cellular regulation of the various adaptations taking place in response to exercise. Changes in the cellular machinery are described for multiple tissues and organs in terms of signaling pathways, gene expression, and protein abundance. Adaptations to acute exercise as well as exposure to regular exercise are also discussed and considered. - Includes a comprehensive summary of the evidence accumulated thus far on the molecular and cellular regulation of the various adaptations taking place in response to exercise - Contains contributions from leading authorities - Informs and updates on all the latest developments in the field of exercise biology and exercise genomics
