Book Description
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 Description
The extremely potent substance botulinum neurotoxin (BoNT) has attracted much interest in diverse fields. Originally identified as cause for the rare but deadly disease botulism, military and terrorist intended to misuse this sophisticated molecule as biological weapon. This caused its classification as select agent category A by the Centers for Diseases Control and Prevention and the listing in the Biological and Toxin Weapons Convention. Later, the civilian use of BoNT as long acting peripheral muscle relaxant has turned this molecule into an indispensable pharmaceutical world wide with annual revenues >$1.5 billion. Also basic scientists value the botulinum neurotoxin as molecular tool for dissecting mechanisms of exocytosis. This book will cover the most recent molecular details of botulinum neurotoxin, its mechanism of action as well as its detection and application.

Book Description
Muscle and Exercise Physiology is a comprehensive reference covering muscle and exercise physiology, from basic science to advanced knowledge, including muscle power generating capabilities, muscle energetics, fatigue, aging and the cardio-respiratory system in exercise performance. Topics presented include the clinical importance of body responses to physical exercise, including its impact on oxygen species production, body immune system, lipid and carbohydrate metabolism, cardiac energetics and its functional reserves, and the health-related effects of physical activity and inactivity. Novel topics like critical power, ROS and muscle, and heart muscle physiology are explored. This book is ideal for researchers and scientists interested in muscle and exercise physiology, as well as students in the biological sciences, including medicine, human movements and sport sciences. Contains basic and state-of-the-art knowledge on the most important issues of muscle and exercise physiology, including muscle and body adaptation to physical training, the impact of aging and physical activity/inactivity Provides both the basic and advanced knowledge required to understand mechanisms that limit physical capacity in both untrained people and top class athletes Covers advanced content on muscle power generating capabilities, muscle energetics, fatigue and aging

Book Description
It is essential for our quality of life to have healthy muscles. Tragically, the loss of even a single protein can have dramatic effects on muscle functioning and quality of life. This book is about skeletal muscles, their physiological complexity and molecular functioning in health and disease. The range of topics varies from the fascinating events at the level of the cross-bridges, the aging process of skeletal muscles, ischemia-reperfusion, inflammatory myopathies and mitochondrial function, muscular dystrophy and the regulation of skeletal muscle mass in health and disease. This book is written by internationally acclaimed researchers and expert research groups and provides state of the art understanding of the plasticity of skeletal muscle, information that is vital for health professionals who deal with diverse chronic disease conditions.
