This book was released on 2012-12-06 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: The publication of the Vth International Symposium 1995 on "Mechanisms of Secondary Brain Damage" in Mauls/ltaly is a collection of focused reviews reaching from novel molecular- and cell biological findings to aspects of clinical management in head injury and cerebral ischemia. A specific purpose of these series of meetings introduced in 1984 is for an exchange on problems of mutual interest by international high ranking experts from the basic sciences and related clinical disciplines, such as intensive care medicine, neurology, or neurosurgery. The present volume covers three major areas: (a) Molecular and cell biological mechanisms including inflammation (b) Novel findings on mechanisms and treatment in cerebral ischemia (c) Secondary processes in head injury, regeneration and treatment Molecular-and cell biology is currently attracting attention towards activation of genomic processes associated with the demise of cells referred to as "programmed cell death" and "apoptosis" which, actually, might be distinguished from each other. Thus, the phenomenon of delayed neuronal death in selectively vulnerable brain areas following brief interruption of blood flow is scrutinized as to the contribution of the activation of suicide genes. The physiological role of such a response, among others, is removal of surplus neurons during ontogenesis of the brain. Yet, evidence is accumulating that similar mechanisms playa role in cerebral ischemia, probably also trauma, where nerve-and other cells demonstrate features of apoptosis. Observations on protection of neurons by administration of protein synthesis inhibitors in cerebral ischemia provide more direct support.

Download or read book Mechanisms of Secondary Brain Damage written by A. Baethmann and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: A distinction between primary and secondary brain damage of vari ous origin, particularly in acute lesions, such as head injury and ische mia is not entirely new. The concept is of practical significance, be cause it is the foremost intention of all clinical efforts to prevent, or at least attenuate the development of secondary sequelae. Primary dam age to nervous elements usually cannot be influenced by treatment. Its prevention is the objective of prophylactic measures. The current volume gathered prominent scientists and clinicians from various fields to pro vide a competent introduction and survey of the various aspects involved in secondary brain damage. It was attempted to provide criteria for the distinction between the primary and secondary phenomena on a morpho logical and functional level, on the basis of the kinetics involved and, most importantly, regarding the different specific manifestations, such as disturbances of microcirculation, aspects of the blood-brain barrier, and of cellular structure and function at a molecular level. Although it was not expected that a grand unifying hypothesis will be reached recon cilable with the many, occasionally opposing views on such a complex subject, nevertheless, the present volume attains an appropriate result. It can best be described as a mosaic of many different pieces which only as an ensemble reflect the current state of the art.
Book Synopsis Maturation Phenomenon in Cerebral Ischemia III by : Umeo Ito
Download or read book Maturation Phenomenon in Cerebral Ischemia III written by Umeo Ito and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Maturation Phenomenon, described by Ito et al. in 1975 [3) on the basis of his to logical observations in the hippocampus as well as other portions of the cerebral hemisphere, refers to the hours or days of delay in the development of pathological changes in various parameters of ischemic injury following the restoration of blood flow to the ischemic brain. There is a direct relationship between the intensity of ischemic insult and the speed and rate of maturation of ischemic injury, a lesser intensity being associated with slower and less severe development of the lesions. The delayed neuronal death of CAl pyramidal cells of the hippocampus [8) is a classic example. In the cerebral cortex, with increasing intensity of the ischemic insult, the maturation phenomenon of ischemic injuries intensifies, seamlessly, from less exten sive to more extensive disseminated selective neuronal necrosis (DSNN), and then further to cerebral infarction upon reaching a critical threshold [1,2,4,6,7). We also have found that following ischemic insults just under the threshold level required to induce infarction, only disseminated selective neuronal necrosis (DSNN) progresses, while following ischemic insults at the threshold level, initially only DSNN develops, followed by the evolution of a gradually enlarging infarcted focus [5, 7). The reporting of this phenomenon boosted research in the field, as it became evi dent that ischemic damage is not a sudden event, but a process potentially susceptible to therapeutic intervention.
Book Synopsis Cerebral Ischemia by : Wolfgang Walz
Download or read book Cerebral Ischemia written by Wolfgang Walz and published by Springer Science & Business Media. This book was released on 1999-03-25 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human brain represents about 2% of the body weight, yet it accounts for approximately 20% of aerobic metabolism. This high dependency on energy-consuming processes is mainly caused by the active transport of ions, which is necessary to compensate for the transmembrane ion currents that are part ofthe complex signaling processes in the brain. Ninety-five percent ofthe brain's ATP is derived from mitochondrial oxidative phosphorylation. Since that organ' s storage capacity for oxygen is minimal, any interruption of oxygen delivery to brain cells willlead to changes in membrane excitability and, there fore, to disruption of neuronal signaling within seconds. It seems that mamma lian brain is especially vulnerable to such an interruption, since oxygen deprivation leads to activation of ion channel mechanisms in neurons that impair their communications. Thus, the function of the brain as a coordinator of vital homeostatic reflexes, and complex body reactions to external challenges, depends critically on the rate of oxygen delivery and oxygen consumption. Oxygen delivery depends on two variables described in the Fick relation ship: volume flow rate ofblood and the arterial oxygen content. A reduction in either of these two variables will have serious effects on vital brain func tions. Reduction of arterial blood flow to the brain can be caused by cardiac arrest, shock, carotid occlusion, Of hypotension (global ischemia). Oxygen content is progressively decreased in asphyxia (including drowning).

Book Synopsis Neurobiology of Ischemic Brain Damage by : K. Kogure
Download or read book Neurobiology of Ischemic Brain Damage written by K. Kogure and published by Elsevier. This book was released on 1993-05-10 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the eight years since the publication of Volume 63 of Progress in Brain Research, on this subject, developments in the research field have been very fast. For example, receptor physiology and pharmacology is now an intensively studied field, and the excitotoxic hypothesis of cell death is commonly accepted. Furthermore, it is recognized that ischemia and other insults give rise to a sustained depression of overall protein synthesis, yet lead to the expression of dormant genes and to synthesis of new proteins. In view of this development, this volume focusses on the cellular and molecular aspects of ischemic brain damage. The book will be of great value to all those interested in the pathophysiology of ischemic and traumatic brain damage.
Book Synopsis Cerebral Ischemia and Basic Mechanisms by : Alexander Hartmann
Download or read book Cerebral Ischemia and Basic Mechanisms written by Alexander Hartmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, one of a series of monographs devoted to the problems of cerebral ischemia and related topics, we present the proceedings of an international conference on Cerebral Ischemia and Basic Mechanisms held in Bad Schachen/Lake Constance, Germany in June 1992. The enormous progress in research recently on the basic mechanisms associated with cerebral ischemia has provided greater insight into the pathophysiological mechanisms of reduced brain perfusion and decreased cerebral metabolism. The high technology instrumentation used to unravel the intricacies of cerebral blood flow and metabolism includes positron emission tomography and magnetic resonance imaging. A description of sophisticated neurophysiological techniques will give the reader insight into new models of reversible and irreversible tissue damage and changes at the molecular level have been described. The therapeutic approaches which have developed from this re search have been or will be used in clinical trials and will open new avenues in the treatment of stroke. The organizers of the meeting would like to thank the advisory board for its helpful suggestions and the Deutsche Forschungsgemeinschaft and other sponsors for their important support.

Book Synopsis Mechanisms of Cerebral Hypoxia and Stroke by : G. Somjen
Download or read book Mechanisms of Cerebral Hypoxia and Stroke written by G. Somjen and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: The articles and short communications in this volume are based on papers pre sented to the Symposium on Cerebral Hypoxia and Stroke held in Budapest in August of 1987. Besides participants at the meeting, three scientists who were invited but could not attend have also contributed chapters to this volume. A synopsis of the general discussion at the conference and a review chapter conclude this volume. To the readers of this book it will not be news that stroke is a worldwide problem. Efforts to cope with this often devastating condition are worldwide also, as attested by the international membership of the conference. It has been said of oxygen deficiency that it not only stops the machine, it also wrecks the machinery. The paramount question in stroke research is this: why can't the brain be restarted after a hypoxic episode in much the same manner as a motor car can when its gas tank is refilled after it stalled because it ran out of fuel? Participants at the Symposium had been requested in advance of the meeting to especially consider a series of specific questions in relation to this general problem. Among these specific questions were: the mechanism of synaptic blockade in hypoxic brain tissue; the transition from reversible to irreversible arrest of function; the nature of postischemic (delayed) cell death; the possible basic differences in the consequences of hypoxia and ischemia; and actual and potential approaches to the prevention and treatment of cell damage in hypoxia and stroke.
Book Synopsis Current Progress in the Understanding of Secondary Brain Damage from Trauma and Ischemia by : A. Baethmann
Download or read book Current Progress in the Understanding of Secondary Brain Damage from Trauma and Ischemia written by A. Baethmann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Information is provided from the basic and clinical sciences on the mechanisms damaging the brain from trauma or ischemia. New aspects involve the endoplasmic reticulum, mitochondrial failure, pathobiology of axonal injury, molecular signals activating glial elements, or the emerging therapeutical role of neurotrophins. Experimental issues involve a better analysis of the ischemic penumbra, the salvagable tissue. Therapeutic contributions reach from the environmental influence to gene expression, including neuroprotection, such as hibernation – mother nature’s experiment – or hypothermia which is reported to induce cell swelling. Treatment issues deal also with thrombolysis and combination therapies, or with the clearance of adverse blood components – LDL/fibrinogen – by a novel procedure using heparin. Other highlights are discussing the specificities of pediatric vs. adult brain trauma, or the evolving role of the Apolipoprotein-E e4 gene in severe head injury. An update is also provided on an online assessment of the patient management during the pre- and early hospital phase in Southern Bavaria. The empirical observation of neuroworsening is analyzed in further details, whether this is a specificity autonomously driving the posttraumatic course. Finally, the unsolved question why drug trials in severe head injury have failed so far in view of the promising evidence from the laboratory is subjected to an expert analysis.
