Download or read book Photochemical and Photobiological Reviews written by Kendric C. Smith and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goals of the science of photobiology can be divided into four categories: to develop (I) ways to optimize the beneficial effects of light on man and his environment, (2) methods to protect organisms, including man, from the detrimental effects of light, (3) photochemical tools for use in studies of life processes, and (4) photochemical therapies in medicine. To achieve these goals will require the knowledgeable collaboration of biologists, chemists, engineers, mathematicians, physicians, and physicists; because photobiology is a truly multidisciplinary science. While a multidis ciplinary science is more intellectually demanding, it also has a greater potential for unexpected breakthroughs that can occur when data from several areas of science are integrated into new concepts for theoretical or practical use. Photochemical and Photobiological Reviews continues to provide in depth coverage of the many specialty areas of photobiology. It is hoped that these reviews will provide an important service to the younger scientists in the field and to senior scientists in related fields, because they provide a ready access to the recent literature in the field, and more importantly, they frequently offer a critical evaluation of the direction that the field is taking, or suggest a redirection when appropriate. Since it is important that this review series remain responsive to the needs of photochemists and photobiologists, the Editor would value com ments and suggestions from its readers.

Book excerpt: Recent Progress in Photobiology contains the proceedings of the Fourth International Photobiology Congress, held in Oxford on July 26-30, 1964 and organized by a committee set up by the British Photobiology Group. Contributors explore the developments in photobiology, particularly with respect to biological structures, chemical changes, and molecular energy. This volume is organized into 10 sections encompassing 33 chapters and begins with an overview of basic photochemical processes that have direct implications on photobiology. The next chapters discuss the photochemistry of nucleic acids and their derivatives, with some reference to their biological significance. The book also studies the visual processes in humans and animals; the structure, pigment chemistry, and function of photoreceptor systems of plant and animal cells; and receptor mechanisms in human vision. The natural photoenvironment and its influence on life and development is also explained, emphasizing how light shapes the ultimate fate of an organism in its habitat. The remaining chapters focus on energy conversion and photosynthesis; micro-irradiation of cells; photochemistry and photobiology of space research; light and melanin pigmentation of the skin; and the effect of light on plant and animal cells. This book will be of interest to biologists and physiologists, as well as to anyone engaged in photobiological research.

Download or read book Molecular Photobiology written by Kendric C. Smith and published by Elsevier. This book was released on 2013-10-22 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Photobiology: Inactivation and Recovery describes the deleterious photochemical reactions occurring in biological systems. This book is composed of 10 chapters that specifically tackle light interactions in the ultraviolet region of the spectrum resulting to damaged proteins and nucleic acids in living systems. This book deals first with the kinds of photochemical reactions that can occur and the possible effects of photochemistry on molecular, cellular, and organismal levels. The succeeding chapters highlight the principle of recovery mechanisms, wherein evidence shows that cells can repair their damaged genetic material, and thus recover from the otherwise inactivating effects of light. The remaining chapters are devoted to the comparison and contrast of some biological effects of ionizing radiation and those of ultraviolet radiation. This book is of value to molecular photobiologists, photochemists, biochemists, and radiation scientists and researchers.
Download or read book The Science of Photobiology written by K. C. Smith and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although there are several excellent books covering a few of the specialized areas of photobiology, at the present time there is no book that covers all areas of the science of photobiology. This book attempts to fill this void. The science of photobiology is currently divided into 14 subspecialty areas by the American Society for Photobiology. The first 14 chapters of this book deal with those subspecialty areas, each written by a leader in the field. Chapter 15, entitled "New Topics in Photobiology," highlights areas of research that may be desig nated sUbspecialties of photobiology in the future. 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 refer ences 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. Whenever practical, a classroom demonstration or simple laboratory exercise has been provided to exemplify one or more major points in a chapter.

Available in PDF, EPUB and Kindle. Book excerpt: Photochemistry and Photobiology of Nucleic Acids: Volume II, Biology is a collection of papers that deals with the biological effects due to stable UV induced alterations in critical cellular macromolecules, including cell death, growth delay, mutagenesis, and carcinogenesis. The papers assume that DNA is the macromolecule most relevant to cell pathology, as well as to the photochemical and photobiological properties of RNA which are essential in cellular functions. One paper investigates the UV-induced cross-linkings of proteins with nucleic acids as a possible cause of biological effects other than just in terms of the damage done to nucleic acids. Other papers discuss the mechanisms of protection against, and in the repair of damage caused by UV photons and by ionizing radiation (also chemical mutagens) in many organisms from viruses to mammalian cells. The repair processes appear to play a role in monitoring and preserving the structural integrity of DNA during physiological processes such as replication and transcription. One paper notes that in experiments on human embryonic lung fibroblasts WI-38 at very high radiation doses, radiation products of Thy in acid-soluble form appear while products from the DNA (acid-precipitable fraction) disappear. The paper suggests that the excision process is therefore selective. The collection is suitable for biochemists, microbiologists, or academicians whose works involve genetics, cancer, and cellular research.

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.
