Photobiology integrates a wide variety of scientific disciplines. As more people become aware of the many ways light interacts with chemical and biological systems, the need for a concise treatment of photobiology has become more critical. Kohen et al. Have written just such a book, intended both as a textbook and as a reference.The authors begin by providing a brief description of the nature of light, how it affects matter, and the means and methods of measuring it. A major section of the book is devoted to how light influences living systems, including discussions of photosynthesis, bioluminescence, regulatory mechanisms, and visual transduction of light. The last half of the book is devoted to the biomedical aspects of light, including photoimmunology, photoallergic reactions and other forms of light sensitivity, the optical properties of skin, and various ways that light can be used in therapy treatments.Useful to photobiologists as a comprehensive overview, this book should also appeal to biomedical researchers and advanced students of photobiology.

Fluorescence is a very powerful tool for work at the frontier of cell biology, photobiology and bioinstrumentation. The stated aim of the workshop was to highlight the significance of fluorescence work for the understanding of cell and tissue physiology, physiopathology and pharmacology, particulary in terms of the analytical use of fluorescent probes in oncology. In the organization of the workshop a multidisciplinary approach was selected. The purpose of the Advanced Research Workshop (ARW) was to bring together researchers in the various disciplines of tissue optics, imaging, microspectrofluorometry and state of the art probes, in order to explore the full benefits that can be derived in biomedicine through the convergence of these approaches. When applied to in vivo and in situ studies, fluorescence and related optical methods enable us to explore within tissues, cells and organelles photon effects previously understood only in solution photochemistry. Processes which can be studied at the molecular level by photophysics, photochemistry and physical chemistry can be evaluated in living tissue by fluorescence spectroscopy and imaging at the intracellular level in terms of structure and function. Thus, fluorescence adds a new dimension to cell biology and physiology. This approach is now supported by a full and versatile, rapidly growing armamentarium of new selective probes for organelles, enzymes, cations, cytoskeleton and metabolic control.

Containing over 150 original photomicrographs accompanied by protocol information, Atlas of Cell Organelles Fluorescence delineates organelles’ structures, interaction, and organization into complexes. It provides a collection that shows living cells under physiopathological conditions and in the context of treatment with carcinogens, xenobiotics, and chemotherapeutic drugs as well as photosensitizers. A guide for therapeutic, diagnostic, or prognostic interpretation of images, and for further research, the atlas helps you identify critical points of attack and suggests possible strategies for investigation.Each section provides a brief introduction and the technical details of the staining methods used. The text identifies the organelles and gives explanations of unusual appearances and the cytochemical reactions when necessary. Additional text is provided where appropriate for extension and implementation of methods being utilized to generate similar results. In all cases the normal and pathological markers and content are presented. The atlas includes a color insert that illustrates characteristic organelle features, microcompartmentalization, and alterations as investigated by one or more probes simultaneously. The book, an exhaustive list of cellular events observed using microfluorometry, supplies a compilation of information spread throughout the literature of the last 30 years. Atlas of Cell Organelles Fluorescence brings the information together and puts it in an easily accessible format.
