Book Description
As traced by Uichael Bradbury in his recently published monograph, The Concept of a BZood-Brain Barrier, the idea of a scientific challenge is just about as old as the twentieth century. Curiously, it remains undefined. Is it a structure or structures as some use the term, or is it a reciprocal per meability, a force-flow relationship, as do others, or is it a group of processes, some more specialized than others? Depend ing upon the observer, the method, and what is observed, it seems to be each of these or all. This Symposium takes as its focus of interest the micro vasculature of the brain and includes considerations of blood flow, the properties of vessel walls and the control of flow and permeability. In addition perturbations that change the characteristics of the flow of materials are given attention. By changing the usual focus of interest, the organizers, Drs. Suddith and Eisenberg, have given a fresh outlook to the subject and now, by publication of the Proceedings, have arranged for wide availability of these interesting papers. Keasley Welch v PREFACE A symposium on the cerebral microvasculature and its function in the blood-brain barrier was held at The University of Texas Medical Branch, Galveston, in the summer of 1979. Investigators from the United States and Europe met to discuss their recent work.

Book Description
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.

Book Description
This volume contains the most recent works on intracranial pressure and neuromonitoring in brain injury selected from 300 abstracts submitted to the 10th International Symposium on Intracranial Pressure. It includes state of the art monitoring of the brain injured patient in intensive care as well as the current state of knowledge in neurochemical and oxygen monitoring of the injured brain. Recent advances in molecular mechanisms of injury and the pathophysiology of ischemia and trauma are also included. "... this publication presents a comprehensive survey of the present state of art in the field and thus gives directions for further research to those engaged in ICP measurement and neuromonitoring”.

Book Description
Brain dysfunction is a major clinical problem in intensive care, with potentially debilitating long-term consequences for post-ICU patients of any age. The resulting extended length of stay in the ICU and post-discharge cognitive dysfunction are now recognized as major healthcare burdens. This comprehensive clinical text provides intensivists and neurologists with a practical review of the pathophysiology of brain dysfunction and a thorough account of the diagnostic and therapeutic options available. Initial sections review the epidemiology, outcomes, relevant behavioral neurology and biological mechanisms of brain dysfunction. Subsequent sections evaluate the available diagnostic options and preventative and therapeutic interventions, with a final section on clinical encephalopathy syndromes encountered in the ICU. Each chapter is rich in illustrations, with an executive summary and a helpful glossary of terms. Brain Disorders in Critical Illness is a seminal reference for all physicians and neuroscientists interested in the care and outcome of severely ill patients.

Book Description
This book offers an extensive review of the most recent data on the pathophysiological role of structural and functional alterations in the microcirculation, particularly focusing on hypertension and diabetes. It covers several relevant and innovative aspects, including the possible mechanisms involved in the development of microvascular remodeling and rarefaction, the technical approaches available for the detection of microvascular alterations, including non-invasive evaluations, the prognostic role of changes in small resistance artery structure, the possibility of preventing or regressing such alterations with appropriate treatment, and the potential clinical advantages of such intervention. A number of innovative areas of research are considered, including the role of the immune system, inflammation and oxidative stress in the development of microvascular alterations. Lastly, it examines the availability of recent non-invasive methods for the evaluation of small resistance artery morphology in the retina, which in the near future may provide a useful tool for the stratification of cardiovascular risk and even for clinical decisions regarding drug treatment, thus providing physicians with a clinically relevant instrument for improving and optimizing the management of hypertensive and diabetic patients. The book provides valuable, clinically relevant information for specialists (cardiology, internal medicine, and endocrinology) and general practitioners, and also offers novel and stimulating data to basic and clinical researchers.
