Download or read book Living Without Oxygen written by Peter W. Hochachka and published by . This book was released on 1980 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innumerable clinical problems have as their basis some derangement in oxygen-dependent metabolism. To explore mechanisms of adjusting to oxygen limitation, Living without Oxygen presents a bestiary of exotic anaerobes that illuminate elements of metabolic biochemistry only dimly seen in studies using standard experimental animals. With their exaggerated anaerobic capabilities, Hochachka's diving mammals, airbreathing fishes, and hypoxia-adapted lower vertebrates allow a detailed assessment of what can and what cannot be adjusted in the process of extending hypoxia tolerance. The book places the enzymatic and biochemical machinery firmly in the biological context and assumes only a modest familiarity with bioenergetics and metabolic biochemistry. The author's clear prose should make this technical presentation pleasantly unintimidating for any physiologist, biochemist, or clinical investigator. The insights of his unique approach make Living without Oxygen essential reading.

Download or read book The Brain Without Oxygen written by P.L. Lutz and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is well known and researched, that deprivation of oxygen to the brain can quickly result in irreversible damage and death. What is less well known, is that some vertebrate species are exceptionally tolerant of brain hypoxia. The Brain Without Oxygen: Causes of failure - Physiological and molecular mechanisms for survival, Third edition, discusses the mechanisms of brain hypoxia tolerance in these exceptional vertebrates, which include diving marine mammals, high altitude dwellers and the hibernating mammal. Special attention is given to the extraordinary adaptations that allow a few turtle and fish species to tolerate months of brain anoxia. This third, fully updated edition addresses the potential of these animal models as targets for human clinical intervention. Perhaps the most interesting of these, are those involved in the suppression of metabolic activities to new set points well below their normoxic minima or maintenance levels. This volume will be valuable reading for researchers in physiology, medicine and general biological sciences, and of great importance to pharmaceutical companies researching novel models for stroke and brain ischemia.

Download or read book Regulation of Tissue Oxygenation Second Edition written by Roland N. Pittman and published by Biota Publishing. This book was released on 2016-08-18 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Oxygen Advantage written by Patrick McKeown and published by HarperCollins. This book was released on 2015-09-15 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: A simple yet revolutionary approach to improving your body’s oxygen use, increasing your health, weight loss, and sports performance—whether you’re a recovering couch potato or an Ironman triathlon champion. With a foreword by New York Times bestselling author Dr. Joseph Mercola. Achieve more with less effort: The secret to weight loss, fitness, and wellness lies in the most basic and most overlooked function of your body—how you breathe. One of the biggest obstacles to better health and fitness is a rarely identified problem: chronic over-breathing. We often take many more breaths than we need—without realizing it—contributing to poor health and fitness, including a host of disorders, from anxiety and asthma to insomnia and heart problems. In The Oxygen Advantage, the man who has trained over 5,000 people—including Olympic and professional athletes—in reduced breathing exercises now shares his scientifically validated techniques to help you breathe more efficiently. Patrick McKeown teaches you the fundamental relationship between oxygen and the body, then gets you started with a Body Oxygen Level Test (BOLT) to determine how efficiently your body uses oxygen. He then shows you how to increase your BOLT score by using light breathing exercises and learning how to simulate high altitude training, a technique used by Navy SEALs and professional athletes to help increase endurance, weight loss, and vital red blood cells to dramatically improve cardio-fitness. Following his program, even the most out-of-shape person (including those with chronic respiratory conditions such as asthma) can climb stairs, run for a bus, or play soccer without gasping for air, and everyone can achieve: Easy weight loss and weight maintenance Improved sleep and energy Increased concentration Reduced breathlessness during exercise Heightened athletic performance Improved cardiovascular health Elimination of asthmatic symptoms, and more. With The Oxygen Advantage, you can look better, feel better, and do more—it’s as easy as breathing.
Download or read book Mitochondria and Anaerobic Energy Metabolism in Eukaryotes written by William F. Martin and published by Walter de Gruyter GmbH & Co KG. This book was released on 2020-12-07 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria are sometimes called the powerhouses of eukaryotic cells, because mitochondria are the site of ATP synthesis in the cell. ATP is the universal energy currency, it provides the power that runs all other life processes. Humans need oxygen to survive because of ATP synthesis in mitochondria. The sugars from our diet are converted to carbon dioxide in mitochondria in a process that requires oxygen. Just like a fire needs oxygen to burn, our mitochondria need oxygen to make ATP. From textbooks and popular literature one can easily get the impression that all mitochondria require oxygen. But that is not the case. There are many groups of organismsm known that make ATP in mitochondria without the help of oxygen. They have preserved biochemical relicts from the early evolution of eukaryotic cells, which took place during times in Earth history when there was hardly any oxygen avaiable, certainly not enough to breathe. How the anaerobic forms of mitochondria work, in which organisms they occur, and how the eukaryotic anaerobes that possess them fit into the larger picture of rising atmospheric oxygen during Earth history are the topic of this book.

Download or read book Oxygen written by Nick Lane and published by Oxford University Press. This book was released on 2002-09-26 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen has had extraordinary effects on life. Three hundred million years ago, in Carboniferous times, dragonflies grew as big as seagulls, with wingspans of nearly a metre. Researchers claim they could have flown only if the air had contained more oxygen than today - probably as much as 35 per cent. Giant spiders, tree-ferns, marine rock formations and fossil charcoals all tell the same story. High oxygen levels may also explain the global firestorm that contributed to the demise of the dinosaurs after the asteroid impact. The strange and profound effects that oxygen has had on the evolution of life pose a riddle, which this book sets out to answer. Oxygen is a toxic gas. Divers breathing pure oxygen at depth suffer from convulsions and lung injury. Fruit flies raised at twice normal atmospheric levels of oxygen live half as long as their siblings. Reactive forms of oxygen, known as free radicals, are thought to cause ageing in people. Yet if atmospheric oxygen reached 35 per cent in the Carboniferous, why did it promote exuberant growth, instead of rapid ageing and death? Oxygen takes the reader on an enthralling journey, as gripping as a thriller, as it unravels the unexpected ways in which oxygen spurred the evolution of life and death. The book explains far more than the size of ancient insects: it shows how oxygen underpins the origin of biological complexity, the birth of photosynthesis, the sudden evolution of animals, the need for two sexes, the accelerated ageing of cloned animals like Dolly the sheep, and the surprisingly long lives of bats and birds. Drawing on this grand evolutionary canvas, Oxygen offers fresh perspectives on our own lives and deaths, explaining modern killer diseases, why we age, and what we can do about it. Advancing revelatory new ideas, following chains of evidence, the book ranges through many disciplines, from environmental sciences to molecular medicine. The result is a captivating vision of contemporary science and a humane synthesis of our place in nature. This remarkable book will redefine the way we think about the world.
