Book Description
The Arthur M. Sackler Colloquia of the National Academy of Sciences address scientific topics of broad and current interest, cutting across the boundaries of traditional disciplines. Each year, four or five such colloquia are scheduled, typically two days in length and international in scope. Colloquia are organized by a member of the Academy, often with the assistance of an organizing committee, and feature presentations by leading scientists in the field and discussions with a hundred or more researchers with an interest in the topic. Colloquia presentations are recorded and posted on the National Academy of Sciences Sackler colloquia website and published on CD-ROM. These Colloquia are made possible by a generous gift from Mrs. Jill Sackler, in memory of her husband, Arthur M. Sackler.

Book Description
Skin color is perhaps the most decisive and abused physical characteristic of humankind. This book presents a multidisciplinary overview of how and why human populations vary so markedly in their skin color. The biological aspects of the pigment cell and its production of melanin are reviewed. The functions of melanin in the skin, brain, eye and ear are considered, and the common clinical abnormalities of pigmentation, such as albinism, are described and illustrated. Detailed reflectance data from worldwide surveys of skin color are also presented. Next, historical and contemporary backgrounds of the phenomenon are explored in relation to the so-called color problem in society. Finally, the possible evolutionary forces that shape human pigmentation are assessed.

Book Description
The most comprehensive and integrated book on pigmentation The Pigmentary System, Second Edition, gathers into one convenient, all-inclusive volume a wealth of information about the science of pigmentation and all the common and rare clinical disorders that affect skin color. The two parts, physiology (science) and pathophysiology (clinical disorders), are complementary and annotated so that those reading one part can easily refer to relevant sections in the other. For the clinician interested in common or rare pigment disorders or the principles of teaching about such disorders, this book provides an immediate and complete resource on the biologic bases for these disorders. For the scientist studying the biology of melanocyte function, the book provides a list of disorders that are related to basic biological functions of melanocytes. New features of this Second Edition include: Completely new section on the basic science of pigmentation – explaining the integration of melanocyte functions with other epidermal cells and with various organ systems like the immune system New chapters on pigmentary disorders related to intestinal diseases, the malignant melanocyte, benign proliferations of melanocytes (nevi) and phototherapy with narrow band UV All clinical chapters include the latest genetic findings and advances in therapy More than 400 color images of virtually all clinical disorders The book is ideal for all dermatologists and especially those interested in disorders of pigmentation. It is of particular use for pediatric dermatologists and medical geneticists caring for patients with congenital and genetic pigmentary disorders. This authoritative volume will fill the gap for dermatology training programs that do not have local experts on pigmentation. Basic and cosmetic scientists studying pigmentation and melanocytes will find the science and clinical correlations very useful in showing human significance and relevance to the results of their studies.

Book Description
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.

Book Description
Pigment spots are the third most common issue addressed by skincare specialists. Both young and elderly clients come with this complaint, many not for the first time. Therefore, specialists who can effectively resolve these problems will undoubtedly be in demand and achieve well-deserved recognition. This book provides complete and reliable information that will help you build a truly effective and safe program for treating pigmented lesions. The book consists of four parts. The first part describes the nature and mechanisms of pigmentation formation, both constitutive (fixed genetically) and facultative (caused by internal or external influences). The stages of melanogenesis, the current understanding of melanocyte physiology and melanin functions, and differences in skin types between people of different ethnic groups are discussed in detail. Special attention is given to factors influencing pigmentation: hormones, stress, inflammation, nutrients, and ultraviolet radiation. Moreover, "new" factors, such as visible light, infrared radiation, and air pollutants, are discussed clearly and comprehensively. This part concludes with a chapter on the evolution of pigmentation. All this information will give you an in-depth understanding of the nature of pigmentation lesions and, thus, the possibilities of effectively combating them. The second part presents clinical types of dyschromia and describes methods for assessing pigmentation. The third and largest part of the book is devoted to methods of pigmentation prevention and treatment available in skincare practice. Modern depigmenting and exfoliating cosmetic products and the dermal targets on which they act are discussed in detail. Also covered are outdated and dangerous ingredients that can still be found on the market. Separate sections are devoted to sunscreens and antioxidants because they are no less important than bleaching agents in the modern concept of working with pigmentation lesions. Furthermore, in this part, the possibilities of physical methodsare discussed with a detailed description of lasers and IPL devices. These methods allow both pigment-producing and pigment-distributing cells of superficial and deep lesions to be targeted. Injection procedures are also touched upon, focusing on their real possibilities and risks, as well as nutraceuticals for skin lightening with proven effectiveness. The last, fourth part, is devoted to treating vitiligo as the most common variant of hypomelanosis. Many different methods and approaches are used for its treatment, which is also relevant for other acquired pathologies associated with loss of pigment or melanocyte function. The book is intended for aestheticians, skincare specialists, dermatologists, specialists in aesthetic medicine, students at medical schools, and all interested persons.
