Book Description
The surface pigmentation of vertebrates is controlled by specialized cells able to synthesize a variety of pigments collectively known as melanins. Recent research has shown that melanins are produced not only in the skin but also in many other sites such as the eye, inner ear, muscles, etc., - where they are engaged in some unanticipated roles. The details of the synthetic pathway, the complexities of its regulation and biological significance that have been unravelled in recent research comprise a fascinating story and are of key importance in understanding the nature of diseases, including malignant melanoma one of the most rapidly spreading cancers.

Book Description
This volume covers all aspects of melanin pigmentation, providing a concise, comprehensive picture of new knowledge gained at the frontiers of research. It draws heavily on the author's 30-year activity in the field and his continuing work with specialists of widely diverse disciplines. The core of the volume deals with the structure, physicochemical properties, and biosynthesis of the major classes of melanin pigments, including neuromelanins. Further discussions include the biology of the various types of pigment-producing cells, the structure and mode of action of tyrosinase, and the chemistry of urinary melanogens and their biomedical applications as metabolic markers of melanocyte activity, especially for the follow-up of malignant melanoma. Finally, the volume considers progress in the photobiology and photochemistry of melanins, with special emphasis on the controversial role of these pigments in skin photoprotection. Melanins and Melanogenesis is ideally suited as a basic guide for newcomers, and a handy source of specific information for practitioners in academic, medical, and industrial settings.

Book Description
This book provides an up-to-date overview of the biological functions of melanins, their biotechnological production, and their industrial applications. The melanins form a group of polymeric pigments found in most organisms. These natural products are generated by the oxidation of phenolic and indolic molecules yielding melanins, which include eumelanin, pheomelanin, pyomelanin, and the allomelanins. These pigments have diverse biological functions, including photoprotection, thermoregulation, antioxidation, virulence, and metal ion sequestration. Melanins have physicochemical properties that have proven useful in the optical, electronic, material, agriculture, cosmetic, pharmaceutical, and medical industries. The chapters in this book provide an in-depth analysis of the current issues and challenges in this field. Topics covered include the properties, biogenesis, and evolution of melanosomes. The book also addresses the synthesis and industrial production of melanins by microorganisms. The metabolic pathways for the synthesis of several types of polymeric pigments in microorganisms and their role in pathogenesis are reviewed. The large-scale production and purification of melanins to provide this product for industrial applications is a formidable challenge. Two chapters present and discuss the state-of-the-art used for the generation of microbial melanin-production strains and the processes for the biotechnological synthesis and purification of these pigments. Melanins are polymers that can interact with metals, a chapter reviews this capacity in the context of technological applications, including electrochemical energy storage and metal recovery. These polymers are materials having favorable characteristics for photonic applications, including UV blocking and broadband absorption. The current advances in the application of these pigments in optically active materials are presented and discussed.

Book Description
Beautiful, empowering, and exhilarating, Melanin Base Camp is a celebration of underrepresented BIPOC adventurers that will challenge you to rethink your perceptions of what an outdoorsy individual looks like and inspire you to being your own adventure. Danielle Williams, skydiver and founder of the online community Melanin Base Camp, profiles dozens of adventurers pushing the boundaries of inclusion and equity in the outdoors. These compelling narratives include a mother whose love of hiking led her to found a nonprofit to expose BIPOC children to the wonders of the outdoors and a mountain biker who, despite at first dealing with unwelcome glances and hostility on trails, went on to become a blogger who writes about justice and diversity in natural spaces. Also included is a guide to outdoor allyship that explores sometimes challenging topics to help all of us create a more inclusive community, whether you bike, climb, hike, or paddle. Join us as we work together to increase representation and opportunities for people of color in outdoor adventure sports.

Book Description
UV radiation is recognized as the major risk factor for skin can cer. For the last three decades the incidence and mortality of skin cancer have been increasing steadily in almost all parts of the world. Unfortunately, there have been very few advances in the management and treatment of skin cancer. In comparison to other malignant tumors, skin cancer offers the unique opportuni ty to identify this tumor at an early stage. Thus, there is strong interest in preventing death by early diagnosis and prompt treat ment. The proceedings of the International Congress on Skin Cancer and UV Radiation which was held in Bochum Germany in October 1996, reflect the newest scientific standards in the field of skin cancer. The conference in Bochum was a platform for leading scientists from all over the world to discuss the complexity and diversity of UV radiation in its interaction with the skin. Starting with basic science like physiology, immunology, and molecular biochemistry of the skin as influenced by UV radiati on, the book presents a profound survey into the field of skin can cer by focusing on the latest scientific results in prevention, early detection, treatment, and epidemiology. The congress in Bochum in 1996 was organized to provide a starting point for coordinated European strategies against skin cancer with internationally renown scientists.

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.
