Available in PDF, EPUB and Kindle. Book excerpt: An Introduction to Microcirculation is written in response to the need for a book containing the most basic information about microcirculation. The book aims to consolidate information gained from the numerous vascular beds that have been used for in vivo microscopic observations, to note the similarities and differences in architecture and function, to reveal the origin of certain terms and concepts, and to discuss hemodynamics of the micro vessels. The book is divided into three parts. Part 1 covers a historical introduction to the study; general anatomical comparisons; the microvasculature of specific organs and tissues; and methods of preparation of tissues for microscopic observation. Part 2 discusses factors that are involved in this process and the exchange in the microcirculation. Part 3 explores the hemodynamics in the microcirculation and quantitative techniques for measurement of velocity and blood pressure. The text is for medical students, graduate students, clinicians, and young investigators who wish to have a greater knowledge on microcirculation and the concepts behind it.

Available in PDF, EPUB and Kindle. Book excerpt: . . . we do not know a truth without knowing its cause. Aristotle Perhaps the greatest hope that may be entertained for a scientific work, whether experimental or theoretical, is that it leads to new thoughts and new avenues of investigation on the part of its readers. In microvascular mechanics, the interplay of rheology, anatomy, and cellular and organ function has only just begun to be addressed. To understand the operational behavior of microcirculation, there is a need to integrate studies at the cellular or molecu lar level with a quantitative, biomechanical description of the circulatory system. The symposium entitled "Frontiers in Cardiopulmonary Mechanics" held in June 1988 at the University of Virginia was intended to provide a fundamental approach to the description of the circulation from the per spective of microvascular mechanics and to examine new methodology that may advance this effort. This book arose out ofthe work presented at the symposium. Aristotle expressed well the need to pursue the causes of a phenomenon in order to achieve a truthful understanding of its nature. In this spirit has each of the quantitative sciences progressed, and in this spirit we hope that this book will provide some understanding of the microvascular events and bio mechanical mechanisms underlying the behavior of circulation in general, and of pulmonary and skeletal muscle microcirculation in particular. The integrated treatment of pulmonary and systemic microcirculation provided here is intended to encourage the cross-fertilization of these two research fields.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the microcirculatory system has added significant value to the analysis of tissue oxygenation and perfusion. While developments in videomicroscopy technology have enabled medical researchers and physicians to observe the microvascular system, the available software tools are limited in their capabilities to determine quantitative features of microcirculation, either automatically or accurately. In particular, microvessel density has been a critical diagnostic measure in evaluating disease progression and a prognostic indicator in various clinical conditions. As a result, automated analysis of the microcirculatory system can be substantially beneficial in various real-time and off-line therapeutic medical applications, such as optimization of resuscitation. This study focuses on the development of an algorithm to automatically segment microvessels, calculate the density of capillaries in microcirculatory videos, and determine the distribution of blood circulation. The proposed technique is divided into four major steps: video stabilization, video enhancement, segmentation and post-processing. The stabilization step estimates motion and corrects for the motion artifacts using an appropriate motion model. Video enhancement improves the visual quality of video frames through preprocessing, vessel enhancement and edge enhancement. The resulting frames are combined through an adjusted weighted median filter and the resulting frame is then thresholded using an entropic thresholding technique. Finally, a region growing technique is utilized to correct for the discontinuity of blood vessels. Using the final binary results, the most commonly used measure for the assessment of microcirculation, i.e. Functional Capillary Density (FCD), is calculated. The designed technique is applied to video recordings of healthy and diseased human and animal samples obtained by MicroScan device based on Sidestream Dark Field (SDF) imaging modality. To validate the final results, the calculated FCD results are compared with the results obtained by blind detailed inspection of three medical experts, who have used AVA (Automated Vascular Analysis) semi-automated microcirculation analysis software. Since there is neither a fully automated accurate microcirculation analysis program, nor a publicly available annotated database of microcirculation videos, the results acquired by the experts are considered the gold standard. Bland-Altman plots show that there is "Good Agreement" between the results of the algorithm and that of gold standard. In summary, the main objective of this study is to eliminate the need for human interaction to edit/ correct results, to improve the accuracy of stabilization and segmentation, and to reduce the overall computation time. The proposed methodology impacts the field of computer science through development of image processing techniques to discover the knowledge in grayscale video frames. The broad impact of this work is to assist physicians, medical researchers and caregivers in making diagnostic and therapeutic decisions for microcirculatory abnormalities and in studying of the human microcirculation.

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.
