Light In Biology And Medicine

Almost all life depends on light for its survival. It is the ultimate basis for the food we eat (photosynthesis), and many organisms make use of it in basic sensory mechanisms for guiding their behaviour, be it through the complex process of vision, or by the relatively more simple photosens itivity of microorganis~urthermore, light has profound implications for the field of medicine, both as a cause of disease (ie UV damage of DNA), and as a therapeutic agent (ie photodynamic therapy). These and other processes are the basis for the science of photobiolog~ which could be defined as the study of the effects of (visible and ultraviolet) light (from both the sun and artificial sources) on living matter. By its very nature, therefore, it is a multidisciplinary science involving branches of biology, chemistry, physics and medicine. This book contains a selection of papers which have been chosen to highlight recent advances in the various disciplines that make up photo biology. Although no book on photobiology can hope to be comprehensive, we hope that this volume includes a representative sample of much of what is new in the field. It is, however, inevitable that some areas will be better represented than others reflecting the biases of conference org anisers and editors.

The production of biological light (ultra-weak photon emission or biophotons) within many types of cells and tissues is characteristic of an alive organism. You will begin a journey of discovery about biophotons in relationship to biological matter and about how such biophotons can be detected utilizing specialized very photon-sensitive technologies. In this book, Roeland Van Wijk provides a unified synthesis that facilitates easy entry into an exciting sub-field of biology. Light in Shaping Life encompasses the history of biophoton research, insight into how biophotons are generated, and into their involvement with life. Also included, is an overview of the potential benefits of such research to a better understanding of health and medicine. There is sequel to Light in Shaping Life available: Biophoton Technology in Energy and Vitality Diagnostics A Multi-disciplinary, Systems biology, and Biotechnology Appraoch Roeland van Wijk, Yu Yan and Eduard van Wijk Meluna, 2017 ISBN 9789081884341

There are probably few people who do not dream of the good old times, when do ing science often meant fascination, excitement, even adventure. In our time, do ing science involves often technology and, perhaps, even business. But there are still niches where curiosity and fascination have their place. The subject of this book, technological as its title may sound, is one of the fortunate examples. It will report on lasers generating the coldest places in the Universe, and on table top laser microtools which can produce a heat "inferno" as it prevails in the interior of the Sun, or simulate, for specific plant cells, microgravity of the space around our plan et Earth. There will be some real surprises for the reader. The applications range from basic studies of the driving forces of cell division (and thus life) via genetic modification of cells (for example, for plant breeding) to medical applications such as blood cell analysis and finally in vitro fertilization. What are these instruments: laser microbeams and optical tweezers? Both are lasers coupled with a fluorescence microscope. The laser microbeam uses a pulsed ultraviolet laser. Light is focused, as well as possible, in space and time, in order to obtain extremely high light intensities - high enough to generate, for a very short instant, extremely hot spots which can be used to cut, fuse or perforate biological material.

This is the third book chronicling the scientific activities of the European Society for Photobiology (ESP). It contains 56 chapters, written by authors from 16 countries, based on presentations at the 3rd Congress of the European Society for Photobiology held in Budapest, Hungary on the 27th August - 2nd September 1989. The science of photobiology, which can simply be defined as the study of the effects of light on living matter, covers so many subject areas that no single book can hope to do justice to them all. This multidisciplinary nature of photobiology is reflected by the material covered in this volume, which contains chapters on such diverse themes as motile photoresponses in bacteria, cancer therapy and photosynthesis. Interestingly, the emphasis placed on various subject areas differs quite markedly from the preceding volume ('Light in Biology & Medicine, volume 1, eds. R. Douglas, J. Moan & F. Dall'Acqua, Plenum Press, 1988). It is hoped that by highlighting different areas of photobiology these and future pUblications emanating from the ESP will, in time, produce a comprehensive record of photobiological research,. not only in Europe but throughout the world. Unlike many conference proceedings all the chapters con tained within this book have been subjected to rigorous peer review and several potential contributions were rejected during the editing process. Furthermore, most manuscripts underwent extensive editing to try and produce chapters of a uniform format and standard.
