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 endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Book Description
This extensively revised third edition provides a practically applicable guide to the pathophysiology, assessment and management of vascular disorders encountered in vascular surgical practice. It features detailed information on the latest developments in the pathophysiology of conditions including atherosclerosis, multi-organ failure, limb compartment syndromes and Raynaud’s phenomenon in a clear easy to digest format. Disorders such as reperfusion injuries, vasculitides, and aortic dissection are covered. Furthermore, key topics in vascular and endovascular practice such as radiation biology and radiation safety are also detailed. Each chapter contains a set of learning objectives and key references, enabling the reader to quickly identify key points. Mechanisms of Vascular Disease: A Textbook for Vascular Specialists comprehensively covers a variety of common and unusual pathophysiologies encountered in vascular surgery, and is an ideal resource for both the trainee, and practicing clinical vascular surgeon seeking an up-to-date resource on the topic.

Book Description
This valuable resource provides a systematic account of the biochemistry of smooth muscle contraction. As a comprehensive guide to this rapidly growing area of research, it covers the structure and characteristic properties of contractile and regulatory proteins, with special emphasis on their predicted function in the live muscle. Also included in this book are intermediate filament proteins, and desmin and vimentin, whose function in smooth muscle is unknown; and several enzymes involved in the phosphorylation-dephosphorylation of contractile and other proteins.

Book Description
This book presents key concepts in the structure and function of vascular smooth muscle cells in health and disease. Supplemental reading may be drawn from the extensive references listed at the end of each chapter. Vascular smooth muscle cell is the major cell type in blood vessels. Dysfunction of vascular smooth muscle cells is an important cause of vascular diseases, for example, atherosclerosis, hypertension, and circulatory shock. Vascular smooth muscle cells are phenotypically plastic, capable of switching between two major phenotypes — contractile/differentiated phenotype and invasive/proliferative phenotype in response to environmental clues. Chapter 1 introduces the major areas of research presented in this monograph. Chapters 2 to 4 address the structure and function of the contractile/differentiated phenotype of vascular smooth muscle cell. Chapters 5 and 6 address the developmental basis of vascular smooth muscle cell phenotype and structure and function of podosomes (invasive organelles) in the invasive/proliferative phenotype of vascular smooth muscle cell. Chapters 7 to 9 address the role of vascular smooth muscle cell dysfunction in vascular diseases — atherosclerosis, hypertension, and circulatory shock.

Book Description
In the last several years, the development of reagents that recognize smooth muscle-specific proteins has enabled researchers to identify smooth muscle cells (SMC) in tissue undergoing both differentiation and repair. These developments have led to increased research on SMC. The latest volume in the Biology of the Extracellular Matrix Series takes a current and all-encompassing look at this growing area of research. Devoted entirely to the subject of SMC, the book covers a diversity of topics-from SMC architecture and contractility to differentiation and gene expression in development. It also examines the proliferation and replication of SMC and its role in pharmacology and vascular disease. A must for cell, developmental, and molecular biologists, this book also will appeal to cardiologists, pathologists, and biomedical researchers interested in smooth muscle cells. - Presents a molecular, genetic, and developmental perspective of the vas smooth muscle cell - Overview sections highlight key points of chapters, including the clinical relevance of the research and expectations for future study - Appeals to both the basic biologist and to the biomedical researcher of vascular disease
