Download or read book Methods in Porphyrin Photosensitization written by David Kessel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of porphyrins for localization and photodynamic therapy of neoplastic disease has been the topic of several international symposia, reviews and books during the preceeding five years. The literature on this topic has continued to grow, as have numbers of presentations at national and international meetings relating to photobiology, chemistry, and lasers. In this volume, it is the intention of the editor to provide both information on current research projects, and detailed methodology used in such investigations. A bibliography on the subjects of porphyrin localization and therapy is included. The manuscripts contained in this volume are based on reports given at a Porphyrin Photosensitization Workshop which was held in Philadel phia, July 6-7, 1984. This Workshop was supported by NIH grant CA 36746, together with funds from the Fogarty International Center. Authors were requested to update their contributions to provide a summary of progress to mid 1985. Manuscripts containing material not presented in Philadelphia are also included, notably a series of articles describ ing current clinical and pre-clinical results from China. Since the Philadelphia Workshop, a meeting was held in Alghero, Sardinia (May, 1985), and additional conferences are now being planned; this attests to the continued interest in photodynamic therapy involving porphyrin photo sensitization.

Book excerpt: Our symposium examines the current status of our knowledge of the photosensitized reactions of nucleic acids and proteins. Significant advances have been made in this area of photobiology since the last international Congress. The first paper will explore the role of molecular oxygen in photosensitized reactions of proteins and nucleic acids. The last three papers are concerned primarily with photosensitized reactions of nucleic acids and their components in which the sensitizer is consumed by bonding covalently with the substrate on irradiation. The best understood reactions of this type are those sensitized by furocoumarins such as 5-methoxypsoralen. These sensitizers show promise in the photochemotherapeutic treatment of proliferative diseases of the skin, such as psoriasis.

Download or read book Photobiology in Medicine written by Giulo Jori and published by Springer Science & Business Media. This book was released on 2013-12-11 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Man has recognised an association of light with life and medicine for over 3000 years. Today the major challenges to this topic include the elucidation of photochemical reactions involved in photobiology at the molecular level. This includes the use of a variety of modem probing techniques that directly measures the reactivity of excited states and free radicals involved in biological reactions. This text-book is based on such an approach and has arisen from some of the lectures delivered at the NATO ASI held at Hotel Capo Caccia near the Centre for Advanced Research in Photobiology (CARP) in Sardegia, Italy. The ASI took place from 30 September -13 October 1993 and involved a total membership of 90. The book, like the NATO ASI itself, is divided into four themes starting with fundamental aspects and ending with complex medically related systems. Thus Theme 1 covers aspects of the underlying photophysics and photochemistry with particular emphasis on modem experimental techniques to study molecular mechanisms of biological processes. Theme 2 applies many of these fundamental studies to the chemical reactions of most relevance to photobiology and photomedicine such as photo-addition, -isomerization, -sensitization and -pigmentation. The third and fourth Themes deal with the deleterious and therapeutic aspects of light with particular emphasis on the use of Photo-Dynamic Therapy (PDT) to treat cancer and on viral and micro bioi infections.
Download or read book The Science of Photobiology written by Kendric C. Smith and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of The Science of Photobiology was published in 1977, and was the first textbook to cover all of the major areas of photobiology. The science of photobiology is currently divided into 14 subspecialty areas by the American Society for Photobiology. In this edition, however, the topics of phototechnology and spectroscopy have been com bined in a new chapter entitled "Photophysics." The other subspecialty areas remain the same, i.e., Photochemistry, Photosensitization, UV Radiation Effects, Environmental Photobiology, Photomedicine, Circadian Rhythms, Extraretinal Photoreception, Vision, Photomorphogenesis, Photomovement, Photosynthesis, and Bioluminescence. This book has been written as a textbook to introduce the science of photobiology to advanced undergraduate and graduate students. The chapters are written to provide a broad overview of each topic. They are designed to contain the amount of information that might be presented in a one-to two-hour general lecture. The references are not meant to be exhaustive, but key references are included to give students an entry into the literature. Frequently a more recent reference that reviews the literature will be cited rather than the first paper by the author making the original discovery. The chapters are not meant to be a repository of facts for research workers in the field, but rather are concerned with demon strating the importance of each specialty area of photobiology, and documenting its relevance to current and/or future problems of man.
Download or read book Current Topics in Contact Dermatitis written by Peter J. Frosch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 617 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years the field of contact dermatitis has increased greatly in importance in dermatology. The variety of exogenous, environmental ly caused dermatoses has undoubtedly expanded over the past few de cades with the increasing number of potentially toxic chemicals, the changes in lifestyle, and the greater life expectancy in industrialized societies. The value of international cooperation in this field has long been realized and acted upon by the International Contact Dermatitis Re search Group (ICDRG). By 1975 the international journal Contact Dermatitis had been founded under the editorship of C. D. Calnan. Thanks largely to the ICDRG and Contact Dermatitis, there were, by 1986, enough additional dermatologists and scientists with a special interest in this area to form the European Environmental and Contact Dermatitis Research Group (EECDRG). Within 2 years they had in stituted the European Society of Contact Dermatitis (ESCD) as an in ternational forum for researchers in the field. The EECDRG decided to hold a symposium in Heidelberg in May 1988, an initiative supported by the ICDRG, and on this occasion the new ESCD held its inaugural session. The Society already has over 200 members and most national contact dermatitis research groups in Europe are already represented; new members are of course welcome. Subgroups and working committees have been formed to address var ious topics including the standardization of patch testing, photoder matology, and bioengineering.

Download or read book Photophysiology written by Arthur C. Giese and published by Elsevier. This book was released on 2013-09-25 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photophysiology: Current Topics in Photobiology and Photochemistry, Volume VI is a collection of papers that discusses photobiological phenomena found on cells of organisms. The papers in this collection deal with specialized areas of photobiology. One paper describes the instruments used in measuring the course of chlorophyll fluorescence in vivo that occurs when a chlorophyll molecule, stimulated by a light source, returns to its ground state from a previous first singlet state, resulting in a light emission lasting for a few nanoseconds. Another paper discusses the mechanism of light-induced carotenoid synthesis in nonphotosynthetic plants, including temperature-independent photochemical reactions, which results in the organism's producing carotenoids on subsequent incubations in darkness. One paper also explains photosensitization observed in mutant cells resulting from exposure to specific wavelength of light in the presence of a natural sensitizer. This paper points out that there are four main groups of photosensitizers, namely, the hypericins, chlorophylls, porphyrins, and psoralens. This book can prove valuable for cell biologists, micro-biologists, students, and researchers involved in the fields of photobiology and photochemistry.

Download or read book Optogenetics written by Hiromu Yawo and published by Springer Nature. This book was released on 2021-01-05 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, now in a thoroughly revised second edition, offers a comprehensive review of the rapidly growing field of optogenetics, in which light-sensing proteins are genetically engineered into cells in order to acquire information on cellular physiology in optical form or to enable control of specific network in the brain upon activation by light. Light-sensing proteins of various living organisms are now available to be exogenously expressed in neurons and other target cells both in vivo and in vitro. Cellular functions can thus be manipulated or probed by light. The new edition documents fully the extensive progress since publication of the first edition to provide an up-to-date overview of the physical, chemical, and biological properties of light-sensing proteins and their application in biological systems, particularly in neuroscience but also in medicine and the optical sciences. Underlying principles are explained and detailed information provided on a wide range of optogenetic tools for the observation and control of cellular signaling and physiology, gene targeting technologies, and optical methods for biological applications. In presenting the current status of optogenetics and emerging directions, this milestone publication will be a “must read” for all involved in research in any way related to optogenetics.
