Book Description
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.

Book Description
Composed of the heart, blood vessels, and blood, the circulatory system delivers oxygen and nutrients to every tissue in the body. At the center of this incredibly complex system is the heart, a strong muscle that continuously pumps blood throughout the body. Striving to promote a basic understanding of the fundamental physical and biological principles underlying circulatory functions, The Circulatory System, Third Edition describes the anatomical features of the system and examines how it responds to a broad range of challenges, such as increased activity, the microgravity of space, and hemorrhage. Packed with full-color photographs and illustrations, this absorbing book provides students with sufficient background information through references, websites, and a bibliography.

Book Description
Oxygen Transport in Red Blood Cells contains the proceedings of the 12th Aharon Katzir Katchalsky Conference held at Tours, France on April 4-7, 1984. Organized into 16 chapters, this book begins with a discussion on the influence of heme pocket geometry on ligand binding to heme proteins. Subsequent chapters describe a genetic approach to producing oxygen affinity differences; clinical importance of the oxygen transport function of preserved red blood cells; methods for the measurement of oxygen equilibrium curves of red cell suspensions and hemoglobin solutions; and aspects of oxygen supply to tissue. Other chapters elucidate interactions between hemoglobin and erythrocyte membrane and membrane protein oxidation; incorporation of allosteric effectors of hemoglobin in red blood cells; and significance of low hemoglobin oxygen affinity.The interaction of ligands and other molecules with hemoglobin and the storage of red blood cells having incorporated exogenous allosteric effectors of hemoglobin are also explained.

Book Description
The placenta is an organ that connects the developing fetus to the uterine wall, thereby allowing nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Proper vascular development in the placenta is fundamental to ensuring a healthy fetus and successful pregnancy. This book provides an up-to-date summary and synthesis of knowledge regarding placental vascular biology and discusses the relevance of this vascular bed to the functions of the human placenta.

Book Description
Platelets in Cardiovascular Disease provides an in-depth and current coverage of relevant platelet biology and antiplatelet therapy that is in clinical use today and potentially for the future. The book provides a succinct overview of the critical role of platelets in cardiovascular medicine. Cardiovascular disease is the leading cause of mortality worldwide, and recent research has found that the platelet is central to the genesis of heart attacks and stroke as well as many of the complications of angioplasty and bypass surgery. An explosion of knowledge of the biology of platelets has established their important role in the formation of blood clots and, perhaps more intriguingly, their role as inflammatory cells. This growth in information has been paralleled by the development of several drugs that can interfere with platelet action and thereby improve patient outcomes. Indeed, several antiplatelet drugs already in development may ultimately lead to marked advances in both the treatment and prevention of cardiovascular disease. Drawing upon a panel of international experts, Platelets in Cardiovascular Disease delivers a concise yet thorough review of the major developments in antiplatelet therapy. Practicing clinicians as well as those involved in the development of new antithrombotic therapies will find the book interesting and useful. Sample Chapter(s). Chapter 1: Platelet Biology the Role of Platelets in Hemostasis, Thrombosis and Inflammation (274 KB). Contents: Platelet Biology: The Role of Platelets in Hemostasis, Thrombosis and Inflammation (R C Becker); Thromboxane Antagonists (B R Dulin & S R Steinhubl); Glycoprotein IIb/IIIa Inhibitors (S J Lehman et al.); ADP Receptor Antagonists (J Karha & C P Cannon); Monitoring Antiplatelet Therapy (P Harrison & A D Michelson); Platelet Genomics (B K Jefferson et al.); Future Strategies for the Development of Antiplatelet Drugs (R A Harrington). Readership: Physicians: cardiologists, vascular medicine specialists, hematologists; physicians in training: fellows, residents, interns; pharmacists; pharmaceutical industry: scientists, sales representatives.

Book Description
Prolonged microgravity exposure during long-duration spaceflight (LDSF) produces unusual physiologic and pathologic neuro-ophthalmic findings in astronauts. These microgravity-associated findings collectively define the Spaceflight Associated Neuro-ocular Syndrome (SANS). In this book, the editors compare and contrast prior published work on SANS by the National Aeronautics and Space Administration’s (NASA) Space Medicine Operations Division with retrospective and prospective studies from other research groups. The book describes the possible mechanisms and potential etiologies for SANS, and provides an update and review on the clinical manifestations of SANS including: unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and focal areas of ischemic retina (i.e., cotton wool spots). The ocular imaging findings (e.g., retinal nerve fiber layer, optic disc, and choroidal changes on optical coherence tomography) of SANS is also described, including the intraorbital and intracranial findings on orbital ultrasound and magnetic resonance imaging. The knowledge gaps for in-flight and terrestrial human research including potential countermeasures for future stud is also explored, including reports on the in-flight and terrestrial human and animal research being investigated by NASA and its partners to study SANS both prospectively and longitudinally and in preparation for future long duration manned missions to space including the moon, the asteroid belt, or Mars. We think this is a unique topic and hope that NASA and its research partners continue to study SANS in preparation for future longer duration manned space missions. Written in an easy-to-read manner, the book adopts a translational approach and explores the science and the clinical manifestations of Space flight associated neuro-ocular syndrome. It is also multi-disciplinary and suitable for both clinicians and researchers in ophthalmology, neurology, and aerospace medicine interested in SANS SANS is a unique space flight disorder that has no terrestrial equivalent. The book involves contributions from international experts across multiple disciplines to tackle the problem of SANS Summarizes and reviews the current findings of SANS, including possible mechanisms and potential etiologies, clinical manifestations, current reports on the in-flight and terrestrial human and animal research, and ocular imaging findings
