Download or read book Melanins Functions Biotechnological Production and Applications written by Guillermo Gosset and published by Springer Nature. This book was released on 2023-05-30 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Living Color written by Nina G. Jablonski and published by Univ of California Press. This book was released on 2012-09-27 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Living Color is the first book to investigate the social history of skin color from prehistory to the present, showing how our body’s most visible trait influences our social interactions in profound and complex ways. In a fascinating and wide-ranging discussion, Nina G. Jablonski begins with the biology and evolution of skin pigmentation, explaining how skin color changed as humans moved around the globe. She explores the relationship between melanin pigment and sunlight, and examines the consequences of rapid migrations, vacations, and other lifestyle choices that can create mismatches between our skin color and our environment. Richly illustrated, this book explains why skin color has come to be a biological trait with great social meaning— a product of evolution perceived by culture. It considers how we form impressions of others, how we create and use stereotypes, how negative stereotypes about dark skin developed and have played out through history—including being a basis for the transatlantic slave trade. Offering examples of how attitudes about skin color differ in the U.S., Brazil, India, and South Africa, Jablonski suggests that a knowledge of the evolution and social importance of skin color can help eliminate color-based discrimination and racism.

The book provides an up-to-date understanding of the progressive mechanisms of oncological development in malignant melanoma, a likely model of malignant progress for other types of cancer, and the ongoing development of novel therapeutics.
Download or read book The Iris written by Kambiz Thomas Moazed and published by Springer Nature. This book was released on 2020-07-24 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The iris is a circular, pigmented tissue that separates the anterior chamber of the eye from the posterior chamber. It has a crucial role on controlling the amount of the light entering the eye through its central opening “the pupil". The Iris has multiple important functions that support and provide image clarity on the retina. However, it is a largely neglected part of the eye, compared to the cornea lens, retina, and optic nerve, and has not been focused on in a comprehensive way until now. The Iris: Understanding the Essentials, combines different aspects of scientific information from a variety of fields, such as anatomy, histopathology, molecular biology, electron microscopy and other diagnostic modalities. Each chapter will include pearls and summary points, and this multi-disciplinary approach helps the clinician diagnose and treat the large variety of diseases that affect the iris, with the main emphasize on pigmentary pathological changes that can affect the color of the eye. Written as a reference review book for universities, practicing ophthalmologists, Ophthalmology residents, pharmaceutical companies and diagnostic equipment manufacturing companies this book summarizes the information in an easy-to-use manner to help the reader better understand the iris, iris structure, physiology and function.
