Book Description
The dance along the artery The circulation on the lymph Are figured in the drift of stars. T. S. Eliot Die Methode ist alles. Carl Ludwig In physiology a spirit of finesse is required. Claude Bernard Armed with modern Doppler instrumentation, scientists can now quantify the red blood cell's "dance along the artery" as well as "the drift of stars. " In disciplines of science and medicine ranging from cardiology to astronomy, the Doppler principle now provides invaluable velo city measurements in the microcosm of capillary beds and in the cosmos. The newest appiication of the ubiquitous Doppler principle, laser-Doppler velocimetry, has been used to measure blood ftow in tissue for just a few years, but we perceived that, like most new techniques, the birth of laser-Doppler blood ftowmetry was not easy, nor was it likely to pass through infancy and reach maturity without difficulty. In physiology and medicine, better techniques for measur ing blood ftow are constantly in demand, but they often exhibit an unfortun ate boom-and-bust cyde: widespread acceptance and uncritical use are soon xiii xiv Preface followed by studies delineating the limits of the method's validity. The technique is then abandoned for the next more fashionable one, thus proving Ludwig's dictum that a given method is everything or nothing depending upon whether one can believe the data it yields.

Book Description
This Advanced Study Institute was held at \-lellesley College, Wellesley, MA. , from 3 to 12 August 1980. It followed by four years the second "Capri ~,chool on Photon Correlation Spectroscopy". During the intervening period there had been many new applications of dynamic light scattering techniques to the study of systems whose properties depend either on collective molecular interactions or on the formation or activity of supramo1ecu1ar structures. Con sequently, emphasis at this conference was on light scattering studies of subjects such as dynamical correlations in dense polymer solutions, phase transitions in gels, spinodal decomposition of binary fluids, Benard instabilities in nonequilibrium fluids, the formation of micelles and phospholipid vesicles, and movements of the molecular assemblies of muscle tissue. The instructional pro gramme also included tutorial lectures on two complementary spec troscopic techniques which have benefited from dramatic advances in instrumentation, these being small angle X-ray (SAXS) and small angle neutron (SANS) scattering. Strong cold neutron and synchro tron X-ray sources have become available, and data now can be acquired rapidly with newly developed position-sensitive detectors. Several reviews of recent applications of SAXS and SANS were also provided. The organizers of the ASI hoped to provide a forum for theoreticians and experimentalists to assess advances in fields which, although related, were sufficiently different that a great deal of unfamiliar information could be communicated. The order ing of the papers in this volume closely approximates that of the talks presented at the Advanced Study Institute.

Book Description
This book offers up-to-date information on all aspects of the use of lasers in endodontics, focusing especially on the various laser applications, including primary and permanent root canal therapies, retreatments, apical surgery and pulp therapy. Every laser technique used in endodontics is carefully described and illustrated, with detailed coverage of both conventional methods and more recent developments such as laser-activated irrigation and photon-induced photoacoustic streaming. In addition, a separate section addresses the basic science of laser dentistry, explaining the physics, describing laser–tissue interactions, and discussing different types of laser. Extensive reference is made to the international literature in order to provide the reader with a clear, evidence-based understanding of the merits of various approaches. In offering a balanced mix of descriptions of clinical applications, clinical data, scientific research and logical criticism, the book will serve as an excellent reference for a wide audience comprising general dentists as well as specialists.

Book Description
This open access book provides a comprehensive overview of the application of the newest laser and microscope/ophthalmoscope technology in the field of high resolution imaging in microscopy and ophthalmology. Starting by describing High-Resolution 3D Light Microscopy with STED and RESOLFT, the book goes on to cover retinal and anterior segment imaging and image-guided treatment and also discusses the development of adaptive optics in vision science and ophthalmology. Using an interdisciplinary approach, the reader will learn about the latest developments and most up to date technology in the field and how these translate to a medical setting. High Resolution Imaging in Microscopy and Ophthalmology – New Frontiers in Biomedical Optics has been written by leading experts in the field and offers insights on engineering, biology, and medicine, thus being a valuable addition for scientists, engineers, and clinicians with technical and medical interest who would like to understand the equipment, the applications and the medical/biological background. Lastly, this book is dedicated to the memory of Dr. Gerhard Zinser, co-founder of Heidelberg Engineering GmbH, a scientist, a husband, a brother, a colleague, and a friend.

Book Description
This book summarizes various tools and techniques used to provide insights into the cellular and molecular pathophysiology of stroke. It also presents rodent animal models to help shed light on the pathophysiology of ischemic stroke. Presenting the latest information on the different types of stroke, including embolic, filament, photothrombotic, and bilateral common carotid artery, the book also describes techniques that are used for confirmation of stroke surgery, such as laser speckle imaging (LSI) and laser Doppler flowmetry (LDF), and discusses the non-human primates that are used in stroke surgery, cerebral venous sinuous thrombosis, and neurobehavioral assessment. Lastly, it analyzes various neuroprotective agents to treat and prevent ischemic stroke, and examines the challenges and advances in treating and preventing acute ischemic stroke.

Book Description
This is the sixth World Glaucoma Association Consensus. The relationship between ocular blood flow and glaucoma has been discussed for more than a century, and still it uniformly fuels debates at glaucoma meetings throughout the world. Clearly, the results of this report will have broad and significant impact on glaucoma research and clinical practice. The global faculty, consisting of leading authorities on the scientific and clinical aspects of ocular blood flow, have met in Fort Lauderdale on May 2, 2009 to discuss the reports and refine the consensus statements.
