Book Description
This book addresses the phenomenon of biological autoluminescence (also known as ultraweak photon emission, UPE, biochemiluminescence, or biophotons) and deals with a very broad spectrum of subjects, ranging from basic observational studies to molecular mechanisms, free-radical processes, physics of electron excitation and photon emission, as well as detection techniques. The chapter topics include UPE in plants, animals, and the human body; microorganisms and subcellular structures; and model systems, illustrating its high prevalence. Several sections of the book provide some backstory, with emphasis on methodology, unresolved questions, and existing controversies. The authors raise and discuss complex, potentially divisive aspects: Are there any reasons to assume the existence of non-chemical interaction in biological systems? Can research results in the field of mitogenetic radiation, delayed luminescence, and oxychemiluminescence of model systems, be correctly interpreted? What does the future hold for this area of research? Altogether, this publication gives the reader a thorough overview of biological autoluminescence (UPE, biophotonics) research, making it ideal for students and researchers who are new to the area as well as those who are specializing in it.

Book Description
Most of the specialists working in this interdisciplinary field of physics, biology, biophysics and medicine are associated with "The International Institute of Biophysics" (IIB), in Neuss, Germany, where basic research and possibilities for applications are coordinated. The growth in this field is indicated by the increase in financial support, interest from the scientific community and frequency of publications. Audience: The scientists of IIB have presented the most essential background and applications of biophotonics in these lecture notes in biophysics, based on the summer school lectures by this group. This book is devoted to questions of elementary biophysics, as well as current developments and applications. It will be of interest to graduate and postgraduate students, life scientists, and the responsible officials of industries and governments looking for non-invasive methods of investigating biological tissues.

Book Description
Preface: Natural products chemistry has a long history, and could be regarded as having its roots in the use of many kinds of herbal mixtures as crude drugs in traditional medicine. Systems of traditional medicine have been practiced in China and Japan for thousands of years, and virtually all regions of the world have used natural materials to treat human disease. It was clear that many plants, herbs, etc. contain components with powerful biological activities. The dawn of modern natural products chemistry began with the isolation of the active component, morphine, from opium. Subsequently, various alkaloids were isolated from medicinal plants and employed clinically. The discovery and the development of penicillin as a microbial metabolite opened up the era of antibiotics, which have saved countless lives in the past half century or so. The isolation and synthesis of steroid hormones resulted in the development of new concepts in molecular stereochemistry and organic synthetic techniques, as did the discovery of bioactive lipids such as prostaglandins and leukatrienes, bioactive peptides such as enkephalins and endetherines, and oligosaccharides, including glycoproteins. Further, the discovery of plant hormones has led to great strides in plant biotechnology, including plant tissue cultures, and derivatives of insect hormones and pheromones are now used as pesticides. Thus, applications of natural products chemistry have become all-pervasive in modern society. Apart from the extensive practical applications of natural products and their derivatives, natural products chemistry has played a central role in the development of modern organic chemistry as a result of its focus on structural and synthetic studies of often highly complex and inaccessible molecules. Biosynthetic studies have also attracted much attention, aiming to answer the questions of why and how such a large number and variety of compounds are synthesised by organisms. Researchers in the field of biosynthesis first focused on elucidation of the pathways of secondary metabolism, and then on the mechanisms, of the enzymes catalyzing the biosynthetic reactions. This was an extremely difficult task, because rather large amounts of enzymes are required for the investigation of reaction mechanisms and the enzyme proteins are often unstable and not easy to purify. However, in recent years the development of molecular biology has made gene and protein engineering rather routine. Thus, studies of mechanistic enzymology can now be conducted with cloned and overexpressed enzyme proteins. It has been shown that the enzymes responsible for the biosynthesis of antibiotics in Streptomyces spp. are encoded in gene clusters. Further, cloning and functional analysis of the genes associated with flavonoid biosynthesis should soon cast light on the interesting question of why flavonoids are ubiquitously present in plant leaves. Life is maintained not only by large molecules such as proteins and nucleic acids, but also by many small molecules which have essential and diverse roles in the physiology of living organisms. Such compounds often have highly specific interactions with target receptors, but the mechanisms involved largely remain to be explored. Current methodology means that this task can be addressed, and this in turn should lead to a host of new applications for natural products and their derivatives. The key may be an interdisciplinary approach taking account of both biological function and molecular behaviour based on precise structure recognition. As we increasingly understand the mechanisms of molecular recognition that operate in nature, many possibilities should open up for artificial control or modification of biological functions, as well as new challenges for synthetic organic chemists. Our intention in this book is to focus on such dynamic aspects of natural products chemistry. By dealing in detail with representative topics to which the most modern techniques of research have been applied, we hope to emphasize the value of combining traditional approaches to natural products chemists with current biochemical and molecular-biological ideas. Each chapter provides sufficient background information and experimental detail to make the subject accessible to non-specialists. It is our hope that these examples of recent progress in key areas of natural products chemistry will stimulate work in related topics by illustrating the power of a modern interdisciplinary approach to the subject.

Book Description
Each contribution is an article in itself, and great effort has been made by the authors to be lucid and not too technical. A few brief highlights of the round-table discussions are given between the chapters. Topics include: Quantum non-locality, the measurement problem, quantum insights into relativity, cosmology and thermodynamics, and possible bearings of quantum mechanics to biology and consciousness. Authors include Yakir Aharanov and Anton Zeilinger, plus Nobel laureates Anthony J. Leggett (2003) and Gerardus ‘t Hooft (1999). Foreword written by Sir Roger Penrose, best-selling author (The Emperor's New Mind) and world-renowned mathematical physicist.

Book Description
This volume contains papers based on the workshop ?Energy and Information Transfer in Biological Systems: How Physics Could Enrich Biological Understanding?, held in Italy in 2002. The meeting was a forum aimed at evaluating the potential and outlooks of a modern physics approach to understanding and describing biological processes, especially regarding the transition from the microscopic chemical scenario to the macroscopic functional configurations of living matter. In this frame some leading researchers presented and discussed several basic topics, such as the photon interaction with biological systems also from the viewpoint of photon information processes and of possible applications; the influence of electromagnetic fields on the self-organization of biosystems including the nonlinear mechanism for energy transfer and storage; and the influence of the structure of water on the properties of biological matter.
