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.

This book was released on 2012-12-06 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many nerve cells of the brain which are not killed outright may suffer delayed death or recovery after ischemic insult. This fact has led to the concept of "maturation phenomenon" of neuronal injuries. Since the 1st International Symposium on Maturation Phenomenon in 1990, new developments, particularly in molecular biology, have been rapidly bringing new information about molecular nature and mechanisms of cell death. This book contains the presentations of the 2nd International Symposium held in Tokyo in April 1996. The latest developments in maturation phenomenon and the present status of investigation are described and further stimulation of research in this field is provided.

This book was released on 2012-12-06 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: The maturation phenomenon, first described by Ito et al. in 1975, refers to postischemic changes that develop hours or days after an ischemic insult. The delayed neuronal death of CA1 pyramidal cells of the hippocampus is a classic example. The report of the phenomenon boosted research in the field, as it became evident that ischemic damage is not a sudden event, but a process potentially susceptible to therapeutic intervention. Since then a growing number of studies have improved our knowledge on mechanisms of cell death and recovery. This volume contains the presentations of the 4th international symposium, held in New Orleans in October/November 1999, grouped in sections covering apoptosis and/or necrosis, neuronal recovery vs. death, and protection against infarction. It outlines the present status of investigations and provides further stimulation for research in this field.

Available in PDF, EPUB and Kindle. Book excerpt: It has been well recognized that following an ischemic insult many nerve cells of the brain are not killed outright, but may suffer a "delayed neuronal death" or even recover. This led to the concept of "maturation phenomenon" with its main implication that the maturation of ischemic lesions may provide a "window of opportunity" i.e. a period of time when the injury to neuronal elements is still reversible, and during which an application of proper therapeutic measures might be successful. The symposium on Maturation Phenomenon in Cerebral Ischemia was the first international meeting focussed primarily on this subject and the resulting publication contains presentations and discussionsby prominent researchers engaged in this field. This book should stimulate further research on potential of brain tissue for recovery, and particularly with regard to a functional recovery of neurons suffering from chronic ischemic injury.

Book excerpt: Young animals were previously shown to be more resistant to ischemia than were adult animals. This difference was attributed to maturation/function of gonads and/or neurons. This study evaluated the existence of age-related changes in transcriptional expression of HSC70, HSP72, and c-fos mRNA intransient global ischemia, and their possible relationship to neuronal cell survival in CA1 hippocampus. The results indicated that ischemic response in young animals compared with that in adult animals showed: (1) more rapid and /or prolonged expression of HSC70, HSP72, and c-fos mRNAs; (2) a marked induction of HSP72 protein; and (3) enhanced pyramidal cell survival. The observed endogenous 'tolerance' of CA1 neurons in young gerbils to ischemia/reperfusion injury may be related to the expression of HSC70, HSP72 and c-fos.

In addition, a new chapter is included on the classification instruments for ischemic stroke and their use in predicting outcomes and therapeutic triage. All of the authors are internationally recognized experts and members of the interdisciplinary stroke team at the Massachusetts General Hospital and Harvard Medical School. The text is supported by numerous informative illustrations, and ease of reference is ensured through the inclusion of suitable tables. This book will serve as a unique source of up-to-date information for neurologists, emergency physicians, radiologists and other health care providers who care for the patient with acute ischemic stroke.
Download or read book Brain Edema XII written by T. Kuroiwa and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 636 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain edema is a simple phenomenon – an abnormal increase of brain tissue volume by the increase of brain tissue water content. However the etiology is not simple and relating to a wide variety of neurological disorders including ischemia, trauma, tumor, hemorrhage and hydrocephalus. It is still a major cause of death in the neurological/neurosurgical ward. This volume is an up-to-date report on progress in brain edema research, diagnosis and treatment, including papers presented at the 12th International Symposium on Brain Edema and Brain Tissue Injury in 2002. Major topics include molecular biology and blood-brain barrier disorders, ischemic and traumatic brain edema, imaging and diagnosis of brain edema, treatment and radiation effect. Various papers in the rapidly growing fields of neuroimaging and molecular medicine are also included.
Download or read book Brain Edema XI written by A.D. Mendelow and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 612 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brain edema is found in a wide variety of clinical disorders including stroke, intracerebral haemorrhage, subarachnoid haemorrhage, head injury, brain tumors and hydrocephalus. This volume brings together clinical and basic scientists from all over the world. Their expertise in the understanding of brain edema and shifts in brain water compartments has led to a further significant step in our understanding of those diseases characterized by brain edema. This book has also drawn on the expertise of the International Advisory Board of the Brain Edema Society, who have carefully summarized each section, thus providing an easy-to-read summary of the latest advances in each subject. The book is therefore much more than a collection of papers: it represents a critical appraisal and puts each paper into modern scientific context. The greatest advances have come from the rapid development of modern imaging techniques, especially with magnetic resonance imaging (MRI). Imaging can now produce "water maps” and "metabolic profiles” that bring brain metabolism and water content right into every clinic with access to MRI. This book provides the background knowledge to understand these pathophysiological changes.
Download or read book Ischemic Blood Flow in the Brain written by Y. Fukuuchi and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because stroke is essentially a disease of the vessels and blood flow, the most fundamental aspects of ischemic blood flow in the brain are under investigation by researchers. Their work was the focus of the sixth in the series of Keio University International Symposia for Life Sciences and Medicine, held in Tokyo in 1999. Selected here are 55 papers from the symposium, covering the buffy coat (glycocalyx) of endothelial cells, the blood-brain barrier and permeability, gene expression, vascular reactivity, dysregulation, inflammatory deterioration, cortical spreading depression, edema, microvascular derangement, and pathology, in ten major sections. The book includes the thought-provoking discussions that followed the presentations, thus providing an invaluable source of up-to-date information not only for researchers investigating microcirculation but also for clinicians implementing the most effective treatment for stroke patients.
