Book Synopsis Oxidative Stress and Neurodegenerative Disorders by : G. Ali Qureshi
Download or read book Oxidative Stress and Neurodegenerative Disorders written by G. Ali Qureshi and published by Elsevier. This book was released on 2007-03-22 with total page 795 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxidative stress is the result of an imbalance in pro-oxidant/antioxidant homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders. * Contains the latest information on the subject of neurodegenerative disorders* Reflects on various factors involved in degeneration and gives suggestions for how to tackle these problems

Book Synopsis Cytochrome Oxidase in Neuronal Metabolism and Alzheimer’s Disease by : Francisco Gonzalez-Lima
Download or read book Cytochrome Oxidase in Neuronal Metabolism and Alzheimer’s Disease written by Francisco Gonzalez-Lima and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on an international symposium titled "Cytochrome oxidase in energy metabolism and Alzheimer's disease," held as a satellite to the 27th meeting of the Society for Neuroscience, New Orleans, 1997. The symposium was dedicated in honor of Dr. Margaret T. T. Wong-Riley because, in our opinion, the cytochrome oxidase histo chemical method introduced by Dr. Wong-Riley in 1979 was the most significant break through to map energy metabolism in the entire brain since the 2-deoxyglucose method introduced by Dr. Louis Sokoloff and colleagues in 1977. Both of these metabolic map ping techniques have made monumental contributions to brain research by allowing an integral view of brain activity. They have also developed into various specialized tech niques, including applications to the human brain. One of these new applications, which is described in detail in this book, is the quantitative cytochrome oxidase cytochemical method used to study Alzheimer's disease. The objective of this book is to describe the role of cytochrome oxidase in neuronal metabolism and Alzheimer's disease. Whether genetic or environmental, the pathogenesis of Alzheimer's disease involves a cascade of multiple intracellular events, eventually re sulting in failure of oxidative energy metabolism. Could impairment of cytochrome oxi dase in energy metabolism initiate the degenerative process? Cytochrome oxidase function and dysfunction are discussed in relationship to neuronal energy metabolism, neurodegen eration, and Alzheimer's disease. The book is made up of 10 chapters, divided into three major parts.
Book Synopsis The Metabolic-Inflammatory Axis in Brain Aging and Neurodegeneration by : Fei Yin
Download or read book The Metabolic-Inflammatory Axis in Brain Aging and Neurodegeneration written by Fei Yin and published by Frontiers Media SA. This book was released on 2017-08-16 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Impairment of energy metabolism is a hallmark of brain aging and several neurodegenerative diseases, such as the Alzheimer’s disease (AD). Age- and disease-related hypometabolism is commonly associated with oxidative stress and they are both regarded as major contributors to the decline in synaptic plasticity and cognition. Neuroinflammatory changes, entailing microglial activation and elevated expression of inflammatory cytokines, also correlate with age-related cognitive decline. It is still under debate whether the mitochondrial dysfunction-induced metabolic deficits or the microglia activation-mediated neuroinflammation is the initiator of the cognitive changes in aging and AD. Nevertheless, multiple lines of evidence support the notion that mitochondrial dysfunction and chronic inflammation exacerbate each other, and these mechanistic diversities have cellular redox dysregulation as a common denominator. This research topic focuses on the role of a metabolic-inflammatory axis encompassing the bioenergetic activity, brain inflammatory responses and their redox regulation in healthy brain aging and neurodegenerative diseases. Dynamic interactions among these systems are reviewed in terms of their causative or in-tandem occurrence and how the systemic environment, –e.g., insulin resistance, diabetes, and systemic inflammation–, impacts on brain function.

Book Synopsis Connecting Energy Metabolism and Neurodegeneration by : Julia P. Zuercher
Download or read book Connecting Energy Metabolism and Neurodegeneration written by Julia P. Zuercher and published by . This book was released on 2017 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pyruvate kinase (PK), an important glycolytic enzyme that catalyzes the final step of glycolysis through an irreversible mechanism to produce energy for the cell, contains nine cysteines, some of which are highly reactive and critical for function. This research sought to develop a protocol to measure quantitatively the functionality of PK under different experimental conditions. Using a three stage, consistent procedure, it was possible to analyze the effects of thiol modification by Ellman’s Reagent (DTNB) and oxidation by hypochlorous acid (HOCl) on PK activity. Results showed that both DTNB and HOCl inhibited activity at high concentrations, which illustrates that some cysteines are essential for PK to catalyze its reaction. Furthermore, analysis of cysteine labeling with 5-iodoacetamidofluorescein on SDS-PAGE demonstrates that not all cysteines must be modified to see inhibitory effects. Additionally, incubation studies with ATP and fructose-1,6-bisphosphate, known regulators with different binding sites in PK, located important cysteines in the enzyme and explored their reactivity and significance. This characterization of the enzyme has notable implications in vivo in that PK could potentially serve a protective role for other cysteine-containing proteins necessary for cellular function that might be more sensitive to the effects of oxidative damage, such as tubulin, tau, or other glycolytic enzymes, accumulated damage to which could lead to neurodegenerative diseases, such as Alzheimer’s disease (AD).

Book Synopsis Oxidative Neural Injury by : Sigrid C. Veasey
Download or read book Oxidative Neural Injury written by Sigrid C. Veasey and published by Springer Science & Business Media. This book was released on 2009-05-28 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty-five years ago, Earl R. Stadtman, PhD discovered that specific enzymes regulating metabolism can be inactivated by oxidation [1]. He later showed that age-related oxidative modification contributes, at least in part, to age-related loss of function of the enzymes [2, 3]. Dr. Stadtman broke the ground for a new field of study to discover how oxidative stress contributes in significant ways to age-related cellular dysfunction and protein accumulation and that oxidation in the aging brain influences Alzheimer’s disease, ischemia-reperfusion injury, amyotrophic lateral sclerosis, and lifespan [4–6]. Today, his research and mentorship have positively influenced the work of hundreds of scientists in this field. We dedicate this book to Dr. Earl R. Stadtman (1912–2008), in celebration of his passion for science and his superior collaborative and mentorship skills. This book is comprised of three sections. The first describes the valuable roles reactive oxygen species (ROS) and reactive nitrogen species (RNS) play in cellular biology. The second section provides an overview of redox imbalance injury with effects on mitochondria, signaling, endoplasmic reticular function, and on aging in general. The third section takes these mechanisms to neurodegenerative disorders and provides a state-of-the-art look at the roles redox imbalances play in age-related susceptibility to disease and in the disease processes. In the first section we attempt to answer a question posed by Dr. Stadtman, ‘‘Why have cells selected reactive oxygen species to regulate cell signaling events’’ [7].
Book Synopsis Mitochondrial Inhibitors and Neurodegenerative Disorders by : Paul R. Sanberg
Download or read book Mitochondrial Inhibitors and Neurodegenerative Disorders written by Paul R. Sanberg and published by Springer Science & Business Media. This book was released on 1999-10-01 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitochondria have long been the Rodney Dangerfield of cellular organelles. Believed to be the remnants of bacterial infection of eukaryotic cells eons ago, the mitochondrion evolved a symbiotic relationship in which it dutifully served as the efficient source of A TP for cell function. The extraordinary dependence of cells on the energy provided by mito chondrial oxidative metabolism of glucose, especially through critical organs such as the heart and brain, is underlined by the fatal consequences of toxins that interfere with the mitochondrial electron transport system. Consistent with their ancestry, the mitochondria have their own DNA that encodes many but not all of their proteins. The mitochon dria and their genes come from the mother via the ovum since sperm do not possess mitochondria. This extranuclear form of inheritance derived exclusively from the female side has proven to be a powerful tool for tracing the evolution by the number of base substitutions in mtDNA. That mitochondrial gene mutations might be a source of human dis ease became evident a decade ago with the characterization of a group of multisystem disorders, typically involving the nervous system, which are transmitted from mother to child. Specific point mutations in mtDNA have been associated with the different syndromes.

Available in PDF, EPUB and Kindle. Book excerpt: The discovery that several major human neurodegenerative diseases are associated with mitochondrial dysfunction has provided new opportunities for a better understanding of these diseases. In this book, major figures in the field offer state-of-the-art reviews of the role of mitochondrial dysfunction and oxidative damage in the pathogenesis of neurodegenerative diseases. Because many of the topics presented overlap with one another, the result is the most comprehensive review of the subject to date. Mitochondria and Free Radicals in Neurodegenerative Diseases begins with a historical overview of the field presented by one of its distinguished founders. The book goes on to supply detailed information on energy metabolism in normal brain function and to explore the role of oxidative damage—which may be a consequence of mitochondrial dysfunction—in the nervous system. Other early chapters focus on energy dysfunction leading to excitotoxic cell damage, the role of mitochondrial toxins in the pathogenesis of animal models of neurodegenerative diseases, and the role of mitochondria in aging. Additional topics include: Neurologic and neuropathologic consequences of mitochondrial disorders The role of mitochondria and oxidative damage in amyotrophic lateral sclerosis, Parkinson's disease, Huntington's disease, Alzheimer's disease, and cerebellar degenerations Using MRI spectroscopy to assess energy defects in patients with neurodegenerative diseases Potential therapies for neurodegenerative diseases The role of glutamate receptor antagonists for therapy Known approaches to improving energy function in mitochondrial disorders Free radical scavengers and other innovative therapeutic approaches Cover image: Three-dimensional reconstruction of an isolated, condensed rat-liver mitochondrion, obtained by electron tomography, courtesy of Dr. Carmen A.
