Book Description
This book was written by many outstanding investigators who have spent decades to study different aspects of blood‐tissue barrier function. They have summarized some of the latest and fascinating development in their fields of research including the blood‐brain barrier, the blood‐retinal barrier, the gut barrier, the blood‐biliary barrier, the blood‐follicle barrier, the blood‐epididymis barrier, the blood‐testis barrier, the tight junction barrier in general as well as barriers in the female reproductive tract. Included are also chapters that focus on topics that are physiologically applicable to all blood‐tissue barriers. Many of these chapters also include information on specific human diseases, such as pathological changes of the gut barrier that cause bowel disorders resulting from inflammation of the epithelial lining in the intestine, and infertility in men as a result of disruption of the blood‐epididymal and/or blood‐testis barriers; and on new therapeutic approaches (e.g., drug delivery across the blood‐brain and the blood‐retinal barriers).

Book Description
Evolving technologies starting with tracer studies, and more recently with genomics and proteomics, have provided novel information about the molecular properties of cerebral endothelium and astrocytes; however, further studies must be done in animal models of neurological diseases and in humans to get a clearer understanding of the pathogenesis of blood-brain barrier (BBB) breakdown in nervous system diseases. In The Blood-Brain and Other Neural Barriers: Reviews and Protocols, experts in the field present a series of cutting-edge protocols which can be used to study the barriers. Opening with detailed information on components of the neurovascular unit as well as the blood-cerebrospinal, blood-retinal, and blood-nerve barriers, the book continues with meticulous techniques to image the barriers in humans and experimental animals, followed by cutting-edge molecular techniques to study the BBB and novel models to study the barriers, and it concludes with techniques for the delivery of therapeutic agents across the BBB. Written in the highly successful Methods in Molecular BiologyTM series format, protocol chapters include introductions to their respective topics, lists of the necessary materials, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and up-to-date, The Blood-Brain and Other Neural Barriers: Reviews and Protocols will aid the research efforts of not only graduate students but also more experienced investigators and support future studies of these vital systems.

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
Handbook of Nutrition, Diet, and the Eye, Second Edition, thoroughly addresses common features and etiological factors on how dietary and nutritional factors affect the eye. The ocular system is perhaps one of the least studied organs in diet and nutrition, yet the consequences of vision loss are devastating. There are a range of ocular defects that have either their origin in nutritional deficiencies/excess or have been shown to respond favorably to nutritional components. Featuring a new section on animal model studies where both the ocular problem and dietary remedies can be varied, there are also new chapters on dietary supplements. - Serves as a foundational collection for neuroscience, neurology and nutrition researchers, illustrating the importance of nutrition and diet in eye health and function - Provides a common language for readers to discuss how nutritional factors and related diseases and syndromes affect the eye - Features new chapters on infectious diseases of the eye where nutrition is a factor - Discusses animal model studies, dietary supplements, natural dietary extracts from around the world, and age-related changes in ocular health

Book Description
The blood-brain barrier is still not completely understood and therefore the subject of fascinating study. How are endogenous substances transported through the blood-brain barrier? What are the known therapeutic and toxic agents? How are they transported across cerebral microvessels? The discussion of these and other questions with far-reaching consequences for all neuroscientists can be found in this volume. This authoritative and up-to-date review of the blood-brain barrier gives a proper understanding of the topic. The experimental principles, the results of very recent research, as well as the implications that experimental research has for clinical treatment are thoroughly covered. Information is given on: - new findings based on classical physiological and pharmacological techniques, - results obtained from brain capillaries in vitro and in culture, - results obtained from the new scanning techniques (PET and MRI), - the immunology of the blood-brain barrier, - trace metal transport, - the pathological breakdown of the barrier and - the modification of drugs to increase their entry into the brain. Here is a source of information that is invaluable to specialists concerned with basic research in the neurosciences, with the design of neuropharmacological agents, with the radiological diagnosis of cerebral pathology or with the treatment of cerebral lesions!

Book Description
The concept of a blood retinal barrier is still relatively new in the ophthalmic literature. fuereas work on the blood-brain barrier was initiated in the first decade of this century, the blood retinal barrier has only recently been defined. Information accu mulated during the last 10 years has shown that the function of the blood-ocular barriers may be better understood if two main barrier systems are considered to exist in the eye. The blood-aqueous barrier regulates the exchanges between the blood and the intraocu lar fluids, and the blood-retinal barrier separates the neural tissue from the blood. Recent studies have shown that the blood-retinal barrier plays a fundamental role in controlling the microenvironment of the retina. Similarly, the significance of the blood-retinal barrier in retinal disease has become increasingly clear. Fluorescein angiography has demonstrated an intricate series of relationships between altera tions of the blood-retinal barrier and diverse retinal diseases, particularly vascular retinopathies and pigment epitheliopathies. Finally, in the past few years, vitreous fluorophotometry has pro vided a new and accurate index of the alteration of the blood-retinal barrier."

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
OCT is a relatively new imaging technique that is becoming increasingly popular among ophthalmologists in both private and academic settings. Imaging has been a slow moving area in ophthalmology for some time, but now OCT is providing another, more detailed source of demonstrable change in the eye, in diagnostic, therapeutic or post-surgical setting. OCT and ultrasound both measure advancing disease states and post surgical healing. The difference is that OCT shows more subtle changes, particularly post-surgically.
