Book Description
Vascular Smooth Muscle: Metabolic, Ionic, and Contractile Mechanisms addresses the vascular smooth muscle function by describing plasma lipoprotein structure, synthesis, and transport in relation to the concepts of altered vascular smooth muscle lipid metabolism leading to the genesis of atherosclerotic disease. This book is organized into six chapters and begins with an introduction to the complexities of energy metabolism and how metabolic events can be correlated with a simultaneous quantitative assessment of smooth muscle mechanics and the contractile machinery at the molecular level. The next two chapters offer the reader a view of smooth muscle membrane properties in terms of the distribution, transport, and metabolic control of electrolytes and specific aspects of ion conductance and electrical activity. This text also explains how smooth muscle cells regulate their contractile activity through regulation of calcium ion fluxes and the interaction, at the molecular level, of calcium ions with regulatory proteins associated with the contractile apparatus. Reference is made to the relation of possible anomalies in cellular or subcellular smooth muscle metabolic and/or ionic events to the bases of certain types of vascular disease. A chapter that examines the events leading to vascular pathology in the form of atherogenesis concludes the book. This book is intended for researchers and clinicians engaged in the study of smooth muscle and related areas.

Book Description
Key workers in vascular medicine and biology apply state-of-the-art techniques in cell and molecular biology to study the endothelial and vascular smooth muscle cells. The distinguished scientists and clinicians open a new area of endocrinology, which sees the vasculature and kidney as endocrine organs and sheds new light on the hormonal regulation of the cardiovascular system. They also add significantly to our current understanding of the autocrine, paracrine, and endocrine regulation of vascular function in health and in those vascular disease states that accompany diabetes mellitus, dyslipidemia, and hypertension. Endocrinology of the Vasculature is the first book to comprehensively and systematically explore the vasculature as an endocrine organ.

Book Description
Research centering on blood flow in the heart continues to hold an important position, especially since a better understanding of the subject may help reduce the incidence of coronary arterial disease and heart attacks. This book summarizes recent advances in the field; it is the product of fruitful cooperation among international scientists who met in Japan in May, 1990 to discuss the regulation of coronary blood flow.

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
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

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.
