Download or read book Mitochondria and the Future of Medicine written by Lee Know and published by Chelsea Green Publishing. This book was released on 2018 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: With information for patients and practitioners on optimizing mitochondrial function for greater health and longevity Why do we age? Why does cancer develop? What's the connection between heart failure and Alzheimer's disease, or infertility and hearing loss? Can we extend lifespan, and if so, how? What is the Exercise Paradox? Why do antioxidant supplements sometimes do more harm than good? Many will be amazed to learn that all these questions, and many more, can be answered by a single point of discussion: mitochondria and bioenergetics. In Mitochondria and the Future of Medicine, Naturopathic Doctor Lee Know tells the epic story of mitochondria, the widely misunderstood and often-overlooked powerhouses of our cells. The legendary saga began over two billion years ago, when one bacterium entered another without being digested, which would evolve to create the first mitochondrion. Since then, for life to exist beyond single-celled bacteria, it's the mitochondria that have been responsible for this life-giving energy. By understanding how our mitochondria work, in fact, it is possible to add years to our lives, and life to our years. Current research, however, has revealed a dark side: many seemingly disconnected degenerative diseases have tangled roots in dysfunctional mitochondria. However, modern research has also endowed us with the knowledge on how to optimize its function, which is of critical importance to our health and longevity. Lee Know offers cutting-edge information on supplementation and lifestyle changes for mitochondrial optimization, such as CoQ10, D-Ribose, cannabinoids, and ketogenic dietary therapy, and how to implement their use successfully. Mitochondria and the Future of Medicine is an invaluable resource for practitioners interested in mitochondrial medicine and the true roots of chronic illness and disease, as well as anyone interested in optimizing their health.
Download or read book Cancer as a Metabolic Disease written by Thomas Seyfried and published by John Wiley & Sons. This book was released on 2012-05-18 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses controversies related to the origins of cancer and provides solutions to cancer management and prevention. It expands upon Otto Warburg's well-known theory that all cancer is a disease of energy metabolism. However, Warburg did not link his theory to the "hallmarks of cancer" and thus his theory was discredited. This book aims to provide evidence, through case studies, that cancer is primarily a metabolic disease requring metabolic solutions for its management and prevention. Support for this position is derived from critical assessment of current cancer theories. Brain cancer case studies are presented as a proof of principle for metabolic solutions to disease management, but similarities are drawn to other types of cancer, including breast and colon, due to the same cellular mutations that they demonstrate.

Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . 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.
Download or read book Neurobiology of the Axon in Health and Disease written by Maren Engelhardt and published by Frontiers Media SA. This book was released on 2019-11-04 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since Santiago Ramón y Cajal sketched his captivating panels of the microscopic structure of the brain with its vast diversity of neuronal morphology over a century ago, scientists have been drawn to this seemingly chaotic network of neurites and processes to uncover how structure relates to function. During the course of a century, we have moved from merely describing neuronal and glial morphology to furthering our understanding of such intricate processes as organelle and factor transport, cellular compartmentalization, neuronal polarity, cytoskeleton dynamics, neurite pathfinding, and the impact of pathophysiological insult on these structures and events. Yet to this day, and likely for the foreseeable future, much work remains to be done to fully grasp the exceptional role of neurites for the function of larger neuronal ensembles and networks. While the somatodendritic domain of neurons has been in the focus of attention for many years, mostly because of its great dynamic remodeling capacity during events of plasticity (e.g. learning), the axonal domain has somehow remained in the background despite the fact that especially recent comprehensive studies from various fields of research underline the axon’s contribution to dynamic plasticity processes. Consequently, this Research Topic focuses on the many exciting aspects of axonal neurobiology – ranging from membrane composition and molecular determination during development to axonal domain specialization and physiology in health and disease. In Chapter 1 “Axons in the PNS”, Bombeiro et al. use immunodeficient mice to study the role of lymphocytes during the regeneration of peripheral nerves, showing that the modulation of immune responses after injury can be an efficient approach to enhance nerve regeneration in the PNS. Using a DRG model, Berbusse et al. identify the onset of damage to mitochondrial structure and dynamics as a key event during early axon degeneration and provide evidence that Nmnat1, a member of the family of nicotinamide-nucleotide adenylyltransferases, can have protective effects by preserving normal mitochondrial integrity and dynamics. In another study of PNS nerve regeneration, Law et al. use proteomics approaches via Mass Spectrometry to provide evidence that rosovitine, a synthetic purine nucleoside analog, can successfully promote PNS axon regeneration. In Chapter 2 “Axonal development in the central nervous system”, Yoshimura et al. analyze specialized axonal domains, namely the axon initial segment and nodes of Ranvier, with regards to their expression profiles of the major scaffolding protein ßIV-spectrin. Super resolution microscopy reveals a potential developmental switch of spectrin isoforms at both axonal domains. In a related study, also using super resolution microscopy, Leterrier et al. examine a potential reciprocal role of membrane partners in ankyrin-G targeting and stabilization at the axonal membrane during development. The authors demonstrate a tight and precocious association of ankyrin-G with its membrane partners. Höfflin et al. address the question of axon initial segment morphology across different cell classes in cortical organotypic slice cultures and find a surprising heterogeneity especially between pyramidal cells and interneurons in primary visual cortex. In a major step towards establishing a successful live label of the axon initial segment, Dumitrescu et al. report the development of a genetically-encoded construct consisting of a voltage-gated sodium channel intracellular domain fused to yellow fluorescent protein (YFP-NaVII-III). Nelson and Jenkins then provide a comprehensive Review article on the axon initial segment and nodes of Ranvier with a special focus on the various scaffolding protein isoforms and their role in human disease. In Chapter 3 “Axonal physiology and plasticity”, Nikitin et al. investigate fast onset dynamics of action potentials during neuronal development in vitro, showing that encoding of high frequencies improves upon culture maturation, accompanied by the development of passive electrophysiological properties and action potential generation. Using pharmacological and RNA interference approaches, Tapia et al. provide evidence that cannabinoid receptors and their ligands can modulate dendritic morphology and thus, indirectly, also affect ankyrin-G accumulation at the axon initial segment. A Mini Review by Zbili et al. discusses the potential impact of subthreshold changes in presynaptic membrane potential before action potential initiation on neurotransmitter release, and which significant impact such mechanisms could have on information processing in neuronal circuits. Yamada and Kuba close this chapter with a Mini Review on axon initial segment plasticity with a particular focus on ion channels and the biophysics of excitability. In Chapter 4 “Axon degeneration and regeneration”, Hamada et al. investigate the often overlooked question to which extent myelin loss affects action potential propagation along distal branch points and axon collaterals. Using the cuprizone demyelination model and optical voltage-sensitive dye imaging, the authors uncover functional consequences of demyelination that reach well beyond the main axon. In a model of mild traumatic brain injury, Vascak et al. demonstrate complex aspects of this injury type on neocortical circuit function, including changes in inhibitory perisomatic input and axon initial segment-driven output in affected layer V neurons. In a Mini Review, Grosch et al. discuss recent advances in the field of Parkinson’s disease with a focus on early degeneration in dopaminergic and serotonergic neurons of the basal ganglia. The last two articles cover the topic of axonal regeneration. Li et al. investigate the role of activated astrocytes in spinal cord lesion and how their functional downregulation via an inhibitor of mitochondrial fission, Mdivi-1, could potentially have positive impact on lesion scar formation and axonal regeneration. In a final Review, Liu et al. highlight recent advances in the development of biomaterial scaffolds and cell transplantation strategies to combine two promising therapeutic approaches for spinal cord injury.
Download or read book The Biopsychosocial Model of Health and Disease written by Derek Bolton and published by Springer. This book was released on 2019-03-28 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book is a systematic update of the philosophical and scientific foundations of the biopsychosocial model of health, disease and healthcare. First proposed by George Engel 40 years ago, the Biopsychosocial Model is much cited in healthcare settings worldwide, but has been increasingly criticised for being vague, lacking in content, and in need of reworking in the light of recent developments. The book confronts the rapid changes to psychological science, neuroscience, healthcare, and philosophy that have occurred since the model was first proposed and addresses key issues such as the model’s scientific basis, clinical utility, and philosophical coherence. The authors conceptualise biology and the psychosocial as in the same ontological space, interlinked by systems of communication-based regulatory control which constitute a new kind of causation. These are distinguished from physical and chemical laws, most clearly because they can break down, thus providing the basis for difference between health and disease. This work offers an urgent update to the model’s scientific and philosophical foundations, providing a new and coherent account of causal interactions between the biological, the psychological and social.

At least three receptors have been identified for which FFA appear to be the endogenous ligands.
Download or read book Ethics Conflict and Medical Treatment for Children E Book written by Dominic Wilkinson and published by Elsevier Health Sciences. This book was released on 2018-08-05 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: What should happen when doctors and parents disagree about what would be best for a child? When should courts become involved? Should life support be stopped against parents' wishes? The case of Charlie Gard, reached global attention in 2017. It led to widespread debate about the ethics of disagreements between doctors and parents, about the place of the law in such disputes, and about the variation in approach between different parts of the world. In this book, medical ethicists Dominic Wilkinson and Julian Savulescu critically examine the ethical questions at the heart of disputes about medical treatment for children. They use the Gard case as a springboard to a wider discussion about the rights of parents, the harms of treatment, and the vital issue of limited resources. They discuss other prominent UK and international cases of disagreement and conflict. From opposite sides of the debate Wilkinson and Savulescu provocatively outline the strongest arguments in favour of and against treatment. They analyse some of the distinctive and challenging features of treatment disputes in the 21st century and argue that disagreement about controversial ethical questions is both inevitable and desirable. They outline a series of lessons from the Gard case and propose a radical new 'dissensus' framework for future cases of disagreement. - This new book critically examines the core ethical questions at the heart of disputes about medical treatment for children. - The contents review prominent cases of disagreement from the UK and internationally and analyse some of the distinctive and challenging features around treatment disputes in the 21st century. - The book proposes a radical new framework for future cases of disagreement around the care of gravely ill people.

Download or read book The Autism Revolution written by Dr. Martha Herbert and published by Ballantine Books. This book was released on 2013-03-12 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: “An in-depth, scientific—yet hopeful and positive—look at how the brain and body work together . . . [Dr. Martha Herbert] has developed a new way of seeing autism.”—Library Journal After years of treating patients and analyzing scientific data, Harvard Medical School researcher and clinician Dr. Martha Herbert offers a revolutionary new view of autism and a transformative strategy for dealing with it. Autism, she concludes, is not a hardwired impairment programmed into a child’s genes and destined to remain fixed forever. Instead, it is the result of a cascade of events, many seemingly minor. And while other doctors may dismiss your child’s physical symptoms—the anxiety, sensory overload, sleeplessness, frequent illnesses or seizures—as coincidental or irrelevant, Dr. Herbert sees them as vital clues to what the underlying problems are, and how to help. Drawing from the newest research, technologies, and insights, as well as inspiring case studies of both children and adults, Dr. Herbert guides you toward restoring health and resiliency in your loved one with autism. Her specific recommendations aim to provide optimal nutrition, reduce toxic exposures, limit stress, and open the door to learning and creativity. As thousands of families who have cobbled together these solutions themselves already know, this program can have dramatic benefits—for your child with autism, and for you, your whole family, and perhaps your next baby as well. “Invaluable . . . a must-read . . . Dr. Martha Herbert gets it. She not only gets it, but she puts it out there in an awesome book so the rest of us can get it, too.”—Autism Watch “[Herbert] goes further than most autism specialists. Her impressive science background merges with common sense and even intuitive sense [making] complex scientific and medical materials seamlessly blend with a holistic viewpoint.”—Relieve Autism “Hope and practical guidance . . . With this easy-to-read book, parents can gain wisdom on how to guide your child to achieve a healthy and thriving life.”—Mom Central
Download or read book Heritable Human Genome Editing written by The Royal Society and published by National Academies Press. This book was released on 2021-01-16 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heritable human genome editing - making changes to the genetic material of eggs, sperm, or any cells that lead to their development, including the cells of early embryos, and establishing a pregnancy - raises not only scientific and medical considerations but also a host of ethical, moral, and societal issues. Human embryos whose genomes have been edited should not be used to create a pregnancy until it is established that precise genomic changes can be made reliably and without introducing undesired changes - criteria that have not yet been met, says Heritable Human Genome Editing. From an international commission of the U.S. National Academy of Medicine, U.S. National Academy of Sciences, and the U.K.'s Royal Society, the report considers potential benefits, harms, and uncertainties associated with genome editing technologies and defines a translational pathway from rigorous preclinical research to initial clinical uses, should a country decide to permit such uses. The report specifies stringent preclinical and clinical requirements for establishing safety and efficacy, and for undertaking long-term monitoring of outcomes. Extensive national and international dialogue is needed before any country decides whether to permit clinical use of this technology, according to the report, which identifies essential elements of national and international scientific governance and oversight.
Download or read book 10 Human written by Alanna Collen and published by HarperCollins. This book was released on 2015-05-05 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now in paperback, evolutionary biologist and science writer Alanna Collen’s stunning alarm call concerning the widely-ignored role our gut microbes play in our health and well-being. “Fascinating…. Everything you wanted to know about microbes but were afraid to ask.”— Kirkus Reviews (starred review) You are just 10% human. For every one of the cells that make up the vessel that you call your body, there are nine impostor cells hitching a ride. You are not just flesh and blood, muscle and bone, brain and skin, but also bacteria and fungi. Over your lifetime, you will carry the equivalent weight of five African elephants in microbes. You are not an individual but a colony. Until recently, we had thought our microbes hardly mattered, but science is revealing a different story, one in which microbes run our bodies and becoming a healthy human is impossible without them. In this riveting, shocking, and beautifully written book, biologist Alanna Collen draws on the latest scientific research to show how our personal colony of microbes influences our weight, our immune system, our mental health, and even our choice of partner. She argues that so many of our modern diseases—obesity, autism, mental illness, digestive disorders, allergies, autoimmunity afflictions, and even cancer—have their root in our failure to cherish our most fundamental and enduring relationship: that with our personal colony of microbes. The good news is that unlike our human cells, we can change our microbes for the better. Collen’s book is a revelatory and indispensable guide. Life—and your body—will never seem the same again.
