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.

Immune Mechanisms of Pain and Analgesia is the first volume to discuss a new concept of immune-neural interplays leading to pain or analgesia. It argues the classical view that pain and its control are restricted to the nervous system, offering a comprehensive overview of the emerging area of immune mechanisms in pain and its control. It challenges the traditional view that pain sensation or suppression is attributed exclusively to the nervous system and presents a critical analysis of this new concept. The book is written by an internationally recognized group of researchers and discusses complex and controversial issues such as cytokines and their pain-exacerbating but also analgesic effects, the production of opioids by immune cells, peripheral analgesic and anti-inflammatory actions of opioids, immunomodulatory effects of opiates, and immunosuppressive effects of pain.

This volume is ideal for individuals interested in taking an in-depth look at how cytokines and chemokines participate in autoimmune disorders, and how cytokines and chemokines can be used as targets for therapeutic intervention. The outstanding features of this book are that it is divided in chapters each focusing on specific, highly prevalent autoimmune disorders. The role of cytokines and chemokines in each of these disorders is dissected in the context of the autoinimune responses that drive these diseases. Importantly, each chapter is meant to provide an in-depth review of how cytokines and chemokines participate in each disease, rather than very specific aspects of cytokine or chemokine biology. The book therefore provides an integrated view of how multiple cytokines and chemokines participate in the initiation and evolution of both systemic and organ-specific pathological immune responses.

All too plausibly, it seems, popes and scientists are warning us of impending collapse-yet humanity and our fellow creatures could still be looking forward to a long and glorious future: at least a million years of peace and personal fulfilment, with abundant and diverse wildlife. But to achieve this we need to re-think everything that we do and take for granted, from the day-to-day mundanities of growing and cooking, to the economy and methods of governance, to the most arcane reaches of science and metaphysics. It all amounts to nothing less than a Renaissance-a re-birth-and the Renaissance to come must be driven and led by us, ordinary Joes and Jos, because the oligarchy of governments, corporates, financiers, and their attendant intellectuals who now dominate the world have largely lost touch with the moral and ecological realities of life. The transformation won't be easy but-the good news!-millions of grassroots initiatives of all kinds the world over are already moving in the right directions.

Bioimaging in life sciences is a burgeoning area that is of growing interest to today's professionals and researchers in the field. This is the first book that bridges the gap between biomedical imaging and the bioscience community. This unique resource gives professionals a detailed understanding of imaging platforms, fluorescence imaging, and fundamental image processing algorithms. Further, it guides readers through the application of advanced image analysis methods and techniques to specific biological problems. The book presents applications that span a wide range of scales, from the detection of signaling events in sub-cellular structures, to the automated analysis of tissue structures. Other critical areas discussed include the dynamics of cell populations and in vivo microscopy. A DVD is also included. It contains full-color images, movies and other valuable supplementary material that further illustrate topics discussed in the book.

Our planet is crowded with a spectacular diversity of living creatures. As a most peculiar fact, the oldest of these are in general the most primitive whereas the most recent are the most advanced. How can evolution be working in order to bring about such a counterintuitive result? This raises the challenging question of a direction of evolution. Is it proceeding in a certain direction, is it improving, is it even accelerating?

By introducing the concept of complexity, the author suggests a new way of describing the process of evolution. In this conception, the human cultural evolution is found to be a continuous extension of biological evolution in a common process of ever increasing complexity, characterized as a stepwise, cumulative progression.

What is man's place in this process? Is it meaningful to reflect upon this at all? In fact, in asking this very question we have at the same time answered it. No other creature would. Our brains provide us with a fantastic range of exclusive cognitive abilities and in this respect we are unique.

In this book, we embark on an innovative, exploratory and inter-disciplinary adventure, step by step following the author towards his quest of investigating evolution, its direction and the place of ourselves in it.

The isolation of leptin in 1994 and its characterization as a factor influencing appetite, energy balance, and adiposity, immediately thrust the polypeptide into the rapidly growing body of literature centered on the physiology of obesity. The growing clinical awareness of obesity as a major health risk in developed societies dovetailed perfectly with any of a number of roles that leptin might play in this abenant physiological condition. Almost unnoticed amidst the excitement generated by early leptin publications was the suggestion that the "fat hormone" might also regulate a wide range of systems and events important to reproduction, including pubertal development, gonadal endocrinology, fettility, and pregnancy. Recognizing this potential, a relatively small cadre of researchers began to examine leptin specifically as a reproductive hormone, thus creating a new and fertile field of investigation. Interest in this area has since gained momentum and an increased number of participants have now made significant contributions to our understanding of many leptin-related mechanisms that are relevant to reproductive biology. Leptin and Reproduction is the first major volume to specifically address leptin as a reproductive hormone and closely examines the advances made in the short time since this field of interest developed. Preeminent researchers ti'om many of the subdisciplines working within this area present a welcomed compendium of the wealth of related literature and voice novel interpretations of cun'ent advances.

From cell division to heartbeat, clocklike rhythms pervade the activities of every living organism. The cycles of life are ultimately biochemical in mechanism but many of the principles that dominate their orchestration are essentially mathematical. The Geometry of Biological Time describes periodic processes in living systems and their non-living analogues in the abstract terms of nonlinear dynamics. Enphasis is given in phase singularities, waves, and mutual synchronization in tissues composed of many clocklike units. Also provided are descriptions of the best-studied experimental systems such as chemical oscillators, pacemaker neurons, circadian clocks, and excitable media organized into biochemical and bioelectrical wave patterns in two and three dimensions. No theoretical background is assumed; the required notions are introduced through an extensive collection of pictures and easily understood examples. This extensively updated new edition incorporates the fruits of two decades' further exploration guided by the same principles. Limit cycle theories of circadian clocks are now applied to human jet lag and are understood in terms of the molecular genetics of their recently discovered mechanisms. Supercomputers reveal the unforeseen architecture and dynamics of three-dimensional scroll waves in excitable media. Their role in life-threatening electrical aberrations of the heartbeat is exposed by laboratory experiments and corroborated in the clinic. These developments trace back to three basic mathematical ideas.

In a ?rst approximation, certainly rough, one can de?ne as non-crystalline materials those which are neither single-crystals nor poly-crystals. Within this category, we canincludedisorderedsolids,softcondensed matter,andlivesystemsamong others. Contrary to crystals, non-crystalline materials have in common that their intrinsic structures cannot be exclusively described by a discrete and periodical function but by a continuous function with short range of order. Structurally these systems have in common the relevance of length scales between those de?ned by the atomic and the macroscopic scale. In a simple ?uid, for example, mobile molecules may freely exchange their positions, so that their new positions are permutations of their old ones. By contrast, in a complex ?uid large groups of molecules may be interc- nected so that the permutation freedom within the group is lost, while the p- mutation between the groups is possible. In this case, the dominant characteristic length, which may de?ne the properties of the system, is not the molecular size but that of the groups. A central aspect of some non-crystalline materials is that they may self-organize. This is of particular importance for Soft-matter materials. Self-organization is characterized by the spontaneous creation of regular structures at different length scales which may exhibit a certain hierarchy that controls the properties of the system. X-ray scattering and diffraction have been for more than a hundred years an essential technique to characterize the structure of materials. Quite often scattering anddiffractionphenomenaexhibitedbynon-crystallinematerialshavebeenreferred to as non-crystalline diffraction.

Bioinformatics is an evolving field that is gaining popularity due to genomics, proteomics and other high-throughput biological methods. The function of bioinformatic scientists includes biological data storage, retrieval and in silico analysis of the results from large-scale experiments. This requires a grasp of knowledge mining algorithms, a thorough understanding of biological knowledge base, and the logical relationship of entities that describe a process or the system. Bioinformatics researchers are required to be trained in multidisciplinary fields of biology, mathematics and computer science. Currently the requirements are satisfied by ad hoc researchers who have specific skills in biology or mathematics/computer science. But the learning curve is steep and the time required to communicate using domain specific terms is becoming a major bottle neck in scientific productivity. This workbook provides hands-on experience which has been lacking for qualified bioinformatics researchers.

Apoptosis is a form of cell death that occurs in a controlled manner and is generally noninflammatory in nature. Apoptosis, or programmed cell death, implies a cell death that is part of a normal physiological process of pruning of unneeded cells. However, many disease conditions utilize apoptosis for pathological ends, resulting in inappropriate cell death and tissue destruction. This book starts with an introduction that reviews the general characteristics of apoptosis, its regulation and its role in physiology and disease. Next, the book focuses on three areas as they relate to inflammatory cells and diseases. The first area consists of chapters on signals for apoptosis important to inflammatory cells, namely growth factors and arachidonic acid metabolism. The next area that the book focuses on are effects at the cellular level, on cell survival versus cell death and signals critical for cell function in both normal and disease states. These topics are covered in chapters on lymphocytes, granulocytes, chondrocytes and keratinocytes. The last area that the book focuses on are events at the level of tissue and disease, looking at the evidence for altered apoptosis and/or apoptotic processes in immune and inflammatory diseases. These topics are covered in chapters on rheumatoid arthritis, osteoarthritis, lupus, psoriasis and renal disease. Together, these chapters will provide the reader with the latest insight in the role of apoptosis in inflammatory cells and diseases.
