This book was released on 2024-01-17 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microcirculation reflects the vascular bridge which is the conduit of blood flow between the arteries and veins in the body. It plays a critical role in the delivery of oxygen and nutrients to the cells of the body while also serving to wash away and eliminate biological waste products of metabolism. A complex interplay exists between the normal structure and function of the larger vessels of the body and the blood coursing through. This book discusses the evolving science in understanding the role of microcirculation in some of the most common and devastating diseases that plague humanity. By understanding the role of microcirculation in the normal feedback mechanisms that balance bleeding and clotting with the opportunities to manipulate this balance to treat disease, the impact on the individual and social burden of arterial and venous occlusive and thromboembolic disease can be substantial. Understanding disease mechanisms and enhancing our collective tools for diagnosis and treatment are some of the greatest challenges facing our global healthcare systems. The chapters in this book serve as a foundation for further research into the quest to reduce, if not eliminate, one of the most significant causes of major morbidity, mortality, and overall loss of quality of life worldwide. Without a doubt, the impact of the body’s microcirculation, as our understanding continues to evolve and as emphasized in this text, cannot and should not be underappreciated.

Available in PDF, EPUB and Kindle. Book excerpt: The microcirculation is highly responsive to, and a vital participant in, the inflammatory response. All segments of the microvasculature (arterioles, capillaries, and venules) exhibit characteristic phenotypic changes during inflammation that appear to be directed toward enhancing the delivery of inflammatory cells to the injured/infected tissue, isolating the region from healthy tissue and the systemic circulation, and setting the stage for tissue repair and regeneration. The best characterized responses of the microcirculation to inflammation include impaired vasomotor function, reduced capillary perfusion, adhesion of leukocytes and platelets, activation of the coagulation cascade, and enhanced thrombosis, increased vascular permeability, and an increase in the rate of proliferation of blood and lymphatic vessels. A variety of cells that normally circulate in blood (leukocytes, platelets) or reside within the vessel wall (endothelial cells, pericytes) or in the perivascular space (mast cells, macrophages) are activated in response to inflammation. The activation products and chemical mediators released from these cells act through different well-characterized signaling pathways to induce the phenotypic changes in microvessel function that accompany inflammation. Drugs that target a specific microvascular response to inflammation, such as leukocyte-endothelial cell adhesion or angiogenesis, have shown promise in both the preclinical and clinical studies of inflammatory disease. Future research efforts in this area will likely identify new avenues for therapeutic intervention in inflammation.

Available in PDF, EPUB and Kindle. Book excerpt: In the past two decades a number of studies have shown that abnormalities in the function and structure of coronary microcirculation can be detected in several cardiovascular diseases. On the basis of the clinical setting in which it occurs, coronary microvascular dysfunction (CMD) can be classified into four types: CMD in the absence of any other cardiac disease; CMD in myocardial diseases; CMD in obstructive epicardial coronary artery disease; and iatrogenic CMD. In some instances CMD represents an epiphenomenon, whereas in others it represents an important marker of risk or may contribute to the pathogenesis of myocardial ischemia, thus becoming a possible therapeutic target. This book provides an update on coronary physiology and a systematic assessment of microvascular abnormalities in cardiovascular diseases, in the hope that it will assist clinicians in prevention, detection and management of CMD in their everyday activity.

Available in PDF, EPUB and Kindle. Book excerpt: This book offers an extensive review of the most recent data on the pathophysiological role of structural and functional alterations in the microcirculation, particularly focusing on hypertension and diabetes. It covers several relevant and innovative aspects, including the possible mechanisms involved in the development of microvascular remodeling and rarefaction, the technical approaches available for the detection of microvascular alterations, including non-invasive evaluations, the prognostic role of changes in small resistance artery structure, the possibility of preventing or regressing such alterations with appropriate treatment, and the potential clinical advantages of such intervention. A number of innovative areas of research are considered, including the role of the immune system, inflammation and oxidative stress in the development of microvascular alterations. Lastly, it examines the availability of recent non-invasive methods for the evaluation of small resistance artery morphology in the retina, which in the near future may provide a useful tool for the stratification of cardiovascular risk and even for clinical decisions regarding drug treatment, thus providing physicians with a clinically relevant instrument for improving and optimizing the management of hypertensive and diabetic patients. The book provides valuable, clinically relevant information for specialists (cardiology, internal medicine, and endocrinology) and general practitioners, and also offers novel and stimulating data to basic and clinical researchers.

This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
