Download or read book The Cerebral Circulation written by Marilyn J. Cipolla and published by Biota Publishing. This book was released on 2016-07-28 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This e-book will review special features of the cerebral circulation and how they contribute to the physiology of the brain. It describes structural and functional properties of the cerebral circulation that are unique to the brain, an organ with high metabolic demands and the need for tight water and ion homeostasis. Autoregulation is pronounced in the brain, with myogenic, metabolic and neurogenic mechanisms contributing to maintain relatively constant blood flow during both increases and decreases in pressure. In addition, unlike peripheral organs where the majority of vascular resistance resides in small arteries and arterioles, large extracranial and intracranial arteries contribute significantly to vascular resistance in the brain. The prominent role of large arteries in cerebrovascular resistance helps maintain blood flow and protect downstream vessels during changes in perfusion pressure. The cerebral endothelium is also unique in that its barrier properties are in some way more like epithelium than endothelium in the periphery. The cerebral endothelium, known as the blood-brain barrier, has specialized tight junctions that do not allow ions to pass freely and has very low hydraulic conductivity and transcellular transport. This special configuration modifies Starling's forces in the brain microcirculation such that ions retained in the vascular lumen oppose water movement due to hydrostatic pressure. Tight water regulation is necessary in the brain because it has limited capacity for expansion within the skull. Increased intracranial pressure due to vasogenic edema can cause severe neurologic complications and death.

Download or read book Transcranial Doppler Sonography written by Rune Aaslid and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every few years a dissertation comes to the area of clinical application of medical technology which carries us forward as on a magic carpet into new regions of understanding and patient care. This book is such a magic carpet. It brings together, in a clear and incisive fashion, important hemodynamic principles with a simple noninvasive method of application to a part of the cerebral vasculature which has been relatively inaccessible. To the lucky and perceptive person who reads this book, a feeling of excitement and hope for progress is engendered. The diligent application of the potentials of transcranial Doppler ultrasound brings new power to our efforts in understanding the cerebral circulation and the causes, treatment and prevention of cerebrovascular disorders. Merrill P. Spencer, M. D. Director Institute of Applied Physiology and Medicine Seattle, Wash. , July 1986 Acknowledgements I am greatly indebted to Prof. He1ge Nornes, Oslo, who introduced me to the fascinating study of cerebral hemodynamics in the early 1970's and since then continually encouraged my interest in this field. It was through his pioneering work on the cerebral circulation-using peroperative electromagnetic flowmetry and Doppler techniques-that the basis was laid for the noninvasive trans cranial approach to the circle of Willis described in this book. I also gratefully acknowledge the stimulating case discussions with Prof. Peter Huber, Berne, at the very early introduction of trans cranial Doppler, the inspiring exchange of ideas with Dr. Merrill P.

Download or read book Early Brain Injury or Cerebral Vasospasm written by HUA FENG and published by Springer Science & Business Media. This book was released on 2010-12-02 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 40 articles provide an extensive coverage of clinical and basic science advances over the last three years of research on subarachnoid hemorrhage-induced brain injuries. Early brain injury, the new frontier of subarachnoid research, which may be a key contributor to the high mortality and morbidity, promotes collaborative efforts from neurosurgery, neurology, neuro-ICU into other interrelated fields and basic neurosciences. For the first time, subarachnoid hermorrhage research is almost equally divided by early brain injury and cerebral vasospasm, mechanistic investigations and therapeutic approaches, demonstrating a translational feature of the future direction.

Download or read book Magnesium in the Central Nervous System written by Robert Vink and published by University of Adelaide Press. This book was released on 2011 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: The brain is the most complex organ in our body. Indeed, it is perhaps the most complex structure we have ever encountered in nature. Both structurally and functionally, there are many peculiarities that differentiate the brain from all other organs. The brain is our connection to the world around us and by governing nervous system and higher function, any disturbance induces severe neurological and psychiatric disorders that can have a devastating effect on quality of life. Our understanding of the physiology and biochemistry of the brain has improved dramatically in the last two decades. In particular, the critical role of cations, including magnesium, has become evident, even if incompletely understood at a mechanistic level. The exact role and regulation of magnesium, in particular, remains elusive, largely because intracellular levels are so difficult to routinely quantify. Nonetheless, the importance of magnesium to normal central nervous system activity is self-evident given the complicated homeostatic mechanisms that maintain the concentration of this cation within strict limits essential for normal physiology and metabolism. There is also considerable accumulating evidence to suggest alterations to some brain functions in both normal and pathological conditions may be linked to alterations in local magnesium concentration. This book, containing chapters written by some of the foremost experts in the field of magnesium research, brings together the latest in experimental and clinical magnesium research as it relates to the central nervous system. It offers a complete and updated view of magnesiums involvement in central nervous system function and in so doing, brings together two main pillars of contemporary neuroscience research, namely providing an explanation for the molecular mechanisms involved in brain function, and emphasizing the connections between the molecular changes and behavior. It is the untiring efforts of those magnesium researchers who have dedicated their lives to unraveling the mysteries of magnesiums role in biological systems that has inspired the collation of this volume of work.

Download or read book 100 Interesting Case Studies in Neurointervention Tips and Tricks written by Vipul Gupta and published by Springer. This book was released on 2019-04-10 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neurointervention is a fast-growing subspecialty, and recent trials have demonstrated its role in ischaemic and haemorrhagic stroke. This has generated tremendous interest among interventional neuroradiology, neurology and neurosurgery communities. Nevertheless, formal teaching programmes that provide the required experience are limited, and many early career practitioners are not exposed to the crucial technical details essential to safely performing the procedure before they start practising independently. The book presents 100 characteristic case studies to illustrate the salient technical and clinical issues in decision-making and problem solving during the procedure. This book conveys the “real-world” issues and solutions that are not addressed in detail in most books. As such it is a practical teaching book with useful “tips and tricks” on how to handle specific challenging situations, and is particularly useful for fellows in neurointervention training programmes..
