In spite of ingenious experiments, imaginative theories, and unshakable faith in supreme forces, there is no way to know how life began. What is certain is that in the course of the development of the universe existing sources of energy fused to generate atoms, and atoms mingled to become small molecules. At some point by chance or design-according to one's belief, but no one's evidence-small molecules such as hydrogen, oxygen, carbon dioxide, water, and ammonia reacted to yield larger molecules with the property most essential to life: self-replication. Such molecules had to achieve a proper balance between the stability needed for their survival in the environment and the mutability for the generation of many forms of life. How amino acids were created or how DNA, RNA, and proteins developed remains a mystery. But we know that a simple core of nucleic acid embedded in a protein coat made the simplest unit of life (except for viroids). Whether viruses are a primitive or degenerated form of life is not known. Once proteins appeared, their great structural plasticity allowed them to react with other elements such as sulfur, iron, copper, and zinc. After an incalculable number of years, some of the proteins became capable of catalyzing the synthesis of new nucleic acids, new proteins, and other compounds such as polysaccharides and lipids.

This book comprehensively summarizes the biological mechanisms of coloration and pattern formation of animals at molecular and cellular level, offering up-to-date knowledge derived from remarkable progress in the last 10 years. The brilliant coloration, conspicuous patterns and spectacular color changes displayed by some vertebrates and invertebrates are generally their strategies of the utmost importance for survival. Consists of mainly three parts, starts with introductory chapter, such as Pigments and Pigment Organelles, Developmental Genetics of Pigment Cell Formation, Adult Pigment Patterns, and Color Changes, this book introduces new pigment compounds in addition to classically known pigments and organelles, explains how the generation of multiple types of pigment cell is genetically controlled, describes the mechanisms underlying the zebrafish stripe formation as well as other animals and also summarizes the mechanism of physiological and morphological color changes of teleost, amphibian and cephalopod. Written by experts in the field, this book will be essential reading for graduate students and researchers in biological fields who are interested in pigmentation mechanisms of animals.

Darkening patches on the skin can result in great distress for the patient. However, definitive diagnosis between the many possible causes and effective treatment can be very hard for the medical practitioner to achieve. This is the first major professional reference with systematic coverage of diagnosis and the various treatment options, and it will be an indispensable clinical reference.

The Vertebrate Pigmentary System: From pigment cells to Disorders provides readers with fundamental knowledge of the structural and functional aspects of vertebrate pigment cells - melanophores and melanocytes - from their origin to different stages of development to related diseases. Chapters of the book explain the specific regulatory receptors and markers, signaling pathways of skin melanocytes along with the diseases (hypopigmentation and hyperpigmentation) in humans associated with their disruption. Concurrently, the etiologies of pigmentary disorders and the various therapeutic approaches for their treatment are presented in focused chapters of the book with updated information from recent publications. A summary of natural product based treatment for hypopigmentation and hyperpigmentation rounds up the contents. This reference is a basic guide for medical students and dermatology residents, and a handy source of information for students, researchers, academicians in the field of pigment cell biology, pharmacology and cosmetology.

The skin is colored by a blend of pigments, which form part of a complex and highly regulated process. Pigmentary defects normally present with dyschromia and can be caused by genetic defects, systemic disease, inflammatory processes, metabolic defects, infections, tumors, or toxic or iatrogenic causes. This atlas is an extensive text written by key opinion leaders within dermatology, it has a comprehensive format that guides the reader through the epidemiology, pathophysiology, diagnosis, treatment, and differential diagnosis of both common and rare pigmentary disorders. It illustrates the diagnosis and recognition of pigmentary disorders with a wide range of images.

For the past decade, it has been apparent to both of us that a reference text covering all aspects of tree defense mechanisms to fungi was missing, needed and long overdue. Such a book would provide a clear, comprehensive overview of how living roots, stems and leaves respond to fungal pathogens. The need for such a book became in creasingly clear to us from our conversations with each other, as well as from our interactions with students and colleagues who desired a sourcebook containing reviews of morphological, biochemical and physiological aspects of host-parasite interactions in trees. During a field trip sponsored by the Forest Pathology Committee of the Ameri can Phytopathological Society, on a bus from one site to another, we decided to take the responsibility to prepare a book of this type and began to plan its composition. To adequately address the topic of this book as we had envisioned it, we believed that well-illustrated chapters were needed in order to reflect the important advances made by the many investigators who have examined the anatomical and physiological changes that occur when trees are attacked by fungi. We are grateful to Dr. Tore Timell, the Wood Science editor for Springer-Verlag, for supporting our efforts and for providing an avenue to publish such a profusely il lustrated volume.

An argument that activity provides a useful template for thinking about representation and that deeds are themselves representational: our representing of the world consists, in part, in certain sorts of deeds that we perform in the world. In Body Language, Mark Rowlands argues that the problem of representation—how it is possible for one item to represent another—has been exacerbated by the assimilation of representation to the category of the word. That is, the problem is traditionally understood as one of relating inner to outer—relating an inner representing item to something extrinsic or exterior to it. Rowlands argues that at least some cases of representation need to be understood not in terms of the word but of the deed. Activity, he claims, is a useful template for thinking about representation; our representing the world consists, in part, in certain sorts of actions that we perform in that world. This is not to say simply that these forms of acting can facilitate representation but that they are themselves representational. These sorts of actions—which Rowlands calls deeds—do not merely express or re-present prior intentional states. They have an independent representational status. After introducing the notion of the deed as a "preintentional act," Rowlands argues that deeds can satisfy informational, teleological, combinatorial, misrepresentational, and decouplability constraints—and so qualify as representational. He puts these principles of representation into practice by examining the deeds involved in visual perception. Representing, Rowlands argues, is something we do in the world as much as in the head. Representing does not stop at the skin, at the border between the representing subject and the world; representing is representational "all the way out."
