Available in PDF, EPUB and Kindle. Book excerpt: In one form or another psoralens have been in use dating back to biblical times for the treatment of depigmented patches of skin. However, it has only been in the past 40 years that the structure and function of psoralens have been elucidated. Although several volumes have been published on photobiology and photomedicine, no one volume has ever been devoted to the psoralen photobiology. In these two volumes we focus on the properties and uses of photoactivated psoralens.In these volumes the various aspects of psoralens are presented in a review of the field as it stands in mid 1986. In retrospect, we may find that this particular time was crucial in the development of new therapeutic modalities as many of the applications of modem molecular biology are beginning to impact on the practice of medicine.This book was written with two purposes in mind. First, to serve as an update (the last collective review of the field was in 1982). Second, it is hoped that newcomers to the fields of photobiology andphotomedicine both scientists and clinicians would find it a useful introduction.

Available in PDF, EPUB and Kindle. Book excerpt: It is not always the case that the subject of a scientific book and its relevance to everyday li fe are so timely. Photobiology and its si ster subject Radiobiology are now a must for understanding the environment we live in and the impact light, ultraviolet light, and radiation have on all aspects of our life. Photobiology is a true interdisciplinary field. Photobiology research plays a direct role in diverse fields, and a glance at the topics of the symposia covered in this book by over 100 articles shows the breadth and depth of knowledge acquired in fundamental research and its impact on the major issues and applied problems the world is facing. Half a century of photobiology research brought about an understanding of the importance of light to life, both as a necessary source of energy and growth as weIl as its possible dangers. Research in photochemistry and photobiology led to the discoveries of ceIlular repair mechanisms of UV induced damages to DNA and this led to understanding of the effects of hazardous environmental chemieals and mutagenecity , and to the development of genetic engineering. This topic was given due emphasis in several symposia and chapters in this book.

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 Research in Photobiology written by A. Castellani and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 730 pages. Available in PDF, EPUB and Kindle. Book excerpt: Every four years the photobio1ogists of the world get together in an International Congress. They discuss and learn not only re search details and findings in their own, often narrow, fields but educate one another broadly in the many biological systems that interact with light. It is this latter purpose that is exemplified by these proceedings - the Symposium papers and Workshop summaries of the VIIth International Congress on Photobiology held in Rome, August 29 - September 3, 1976. Photobiology is one of the few true interdisciplinary fields. It has an air of excitement about it. A glance at the table of contents indicates clearly that photobiology and its practitioners (individuals whose primary interests are in medicine, plant sci ences, animal sciences, molecular properties, and energy conversion) interact with the entire and diverse world of living creatures. We supply not only the basic research background to help evaluate many present-day environmental problems but are also evaluating and pointing the way toward solutions to a number of these problems.

Available in PDF, EPUB and Kindle. Book excerpt: This Conference on biomedical applications of. lasers ~Ias organized by the Quantum Electronics Divisional Board of the European Physical Society (E.P.S.) and held at the Villa of Poggio Imperiale in Florence, September 3-6, 1979. As kno~m, laser surgery (especially microsurgery and endoscopic photo coagulation) has recently made important progress, and the field is expand i ng rapidly. Very significant applications of lasers have also been achieved in Bi ology during recent years (cell microsurgery, cell counting and sorting, cytofluorimeter devices, etc.) and the potential of laser techniques in this field is nO~1 sufficiently well establ ished. A new class of applications of laserradiJtion in Medicine has recently been made possible by important results obtained with low intensity (non coagulative) visible lasers, such as photodynamic therapy of tumors. At the same time important branches of Medicine, where light effects are studied and optical techniques are presently used for a certain number of clinical applications, such as dermatology and pediatry, appear to be still in their infancy as far as the proper use of optical radiation and techniques, and the understanding of fundamental photoinduced biological processes are con cerned. Moreover, laser photobiology appears a very promising field for the investigation of fundamental processes at the biomolecular level.

Download or read book DNA Photodamage written by Roberto Improta and published by Royal Society of Chemistry. This book was released on 2021-12-06 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Induction of DNA damage by sunlight is a major deleterious event in living organisms. Recent developments have dramatically improved our understanding of the photochemical processes involved at the sub-picosecond time scale and along with next generation sequencing and data processing has generated a need for a complete up-to-date coverage of the field. Written in an accessible and comprehensive manner, DNA Photodamage will appeal to all scientists working in the area whether specialists in the discipline or not and provides a complete coverage of the field, from ultrafast spectroscopy to biomedical research. Bridging the gap between photophysical and photochemical research on model systems, and in vivo and in vitro biological studies, this book aims to identify the most important research trends in the field and review their major findings.
Download or read book DNA Damage and Repair in Human Tissues written by Betsy M. Sutherland and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical and chemical agents in the environment damage the DNA of humans, and pose a major threat to human health today, and to the genetic integrity of human populations. Although studies on isolated DNA in vitro, on prokaryotes, on mammalian cells in culture, and on laboratory animals have provided essential background information, it is now possible to study DNA damage and repair in human tissues directly. New techniques of high sensitivity, especially those not requiring radioactive labeling have made possible quantitation of DNA damage and repair, as well as detection of residual, unrepaired DNA lesions . In recent years, several investigators have taken up the challenge of studying damage and repair responses in humans, and we have chosen that work as the special focus of this Symposium. Major advances in under standing damage and responses in human skin, in blood cells and in human internal organs indicate three major themes. First, DNA damage levels in human tissues depend not only on the initial exposures, but also on the capapacity of that tissue for repair of the specific lesion type. Second, repair in human tissues may differ quantitatively and qualitatively from that in human cells in culture.
Download or read book Photobiology written by Lars Olof Björn and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photobiology - the science of light and life - begins with basic principles and the physics of light and continues with general photobiological research methods, such as generation of light, measurement of light, and action spectroscopy. In an interdisciplinary way, it then treats how organisms tune their pigments and structures to the wavelength components of light, and how light is registered by organisms. Then follow various examples of photobiological phenomena: the design of the compound eye in relation to the properties of light, phototoxicity, photobiology of the human skin and of vitamin D, photomorphogenesis, photoperiodism, the setting of the biological clock by light, and bioluminescence. A final chapter is devoted to teaching experiments and demonstrations in photobiology. This book encompasses topics from a diverse array of traditional disciplines: physics, biochemistry, medicine, zoology, botany, microbiology, etc., and makes different aspects of photobiology accessible to experts in all these areas as well as to the novice.
Download or read book The Science of Photomedicine written by J.D. Regan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the history of photomedicine dates back thousands of years, with even preliterate cultures appreciating the healing properties of sunlight, for many workers in the discipline photomedicine is associated with the observation about 100 years ago of Niels Finsen, a Danish physician. Finsen recognized that people with tuberculosis who lived in Norway and who had very little exposure to sunlight often developed facial lesions (lupus vulgaris) which would decrease and sometimes disappear during the summer months. This very observant physician reasoned that artificial light ought to produce the same effect as sunlight and began utilizing the radiation from the newly available carbon arc. At first, he used a glass lens to concentrate the radiation, but since this produced considerable burning, he replaced this with a hollow glass lens filled with water. However, while this reduced the heat burns, it did not actually duplicate the effect of direct sunlight. Finally, using a hollow lens filled with water but equipped with quartz windows, Finsen was able to imitate, even improve upon, the effect of sunlight. As a result, lupus vulgaris was practically eliminated from the Scandinavian countries.
