"Our intimate connection with the world, skin protects us while advertising our health, our identity, and our individuality. This synthetic overview, written with a poetic touch and taking many intriguing side excursions, is a guidebook to the pliable covering that makes us who we are. This book celebrates the evolution of three unique attributes of human skin: its naked sweatiness, its distinctive sepia rainbow of colors, and its remarkable range of decorations. Author Jablonski begins with a look at skin's structure and functions and then tours its three-hundred-million-year evolution, delving into such topics as the importance of touch and how the skin reflects and affects emotions. She examines the modern human obsession with age-related changes in skin, especially wrinkles, then turns to skin as a canvas for self-expression, exploring our use of cosmetics, body paint, tattooing, and scarification"--Publisher's description.

Although a very fragile structure, the skin barrier is probably one of the most important organs of the body. Inward/out it is responsible for body integrity and outward/in for keeping microbes, chemicals, and allergens from penetrating the skin. Since the role of barrier integrity in atopic dermatitis and the relationship to filaggrin mutations was discovered a decade ago, research focus has been on the skin barrier, and numerous new publications have become available. This book is an interdisciplinary update offering a wide range of information on the subject. It covers new basic research on skin markers, including results on filaggrin and on methods for the assessment of the barrier function. Biological variation and aspects of skin barrier function restoration are discussed as well. Further sections are dedicated to clinical implications of skin barrier integrity, factors influencing the penetration of the skin, influence of wet work, and guidance for prevention and saving the barrier. Distinguished researchers have contributed to this book, providing a comprehensive and thorough overview of the skin barrier function. Researchers in the field, dermatologists, occupational physicians, and related industry will find this publication an essential source of information.

The Structure and Function of Skin, Third Edition is devoted to all matters pertaining to the structure and function of the skin. Drawing upon the accumulated data derived from embryology, histology, anatomy, physiology, biochemistry, and pharmacology, this book presents an overview of skin, with emphasis on human skin. Topics range from the biological functions of the dermis to the histochemical and microchemical properties of the epidermis; the effects of protein deficiency on hair growth; cutaneous innervation; nail regeneration and growth; sebaceous glands; and eccrine sweat glands. This book is organized into 12 chapters and begins with an overview of the structure and function of skin, and then discusses the epidermis and its structural features. Special consideration is given to the life cycle of epidermal cells; the properties and function of stratum corneum; and other cells in the epidermis including melanocytes, the cells of Langerhans, and Merkel cells. The chapters that follow focus on age-related changes in the dermis, cutaneous blood flow, changes in skin circulation, and the dermal nerve network. The book also considers hair growth and differentiation; the effects of malnutrition on the morphology of hair roots; and the structure and development of the nails. A chapter describing the cytochemistry and pharmacology of eccrine sweat glands concludes the book. This book is written primarily for dermatologists, whether seasoned veterans or neophytes, and will also be useful to all biologists who are interested in biomedical disciplines.

This book presents the scientific evidence for the role of vitamin C in health and disease and offers new guidance on vitamin C intake in humans. The importance of vitamin C in preventing cancer and cardiovascular disease, its relevance to aging and stress, and its impacts on each of the human body systems are thoroughly assessed on the basis of the author’s extensive research and his deep understanding, as an anatomy professor, of the body as a whole. Findings published in the international scientific literature are fully taken into account, and due consideration is also given to empirical evidence, bearing in mind that mechanisms of action cannot always be precisely defined in the absence of human experiments. Beyond providing an up-to-date scientific perspective on the effects of vitamin C, the author hopes to promote human health worldwide by encouraging proper use of the vitamin. To this end, recommendations are made on the amount of vitamin C that should be taken daily and on the best way to take it. The book will be of interest to researchers, clinicians, and all others who wish to learn more about this vitamin and its significance.

Named a Best Book of 2020 by NPR and Vanity Fair One of Smithsonian's Ten Best Science Books of 2020 “A searching and vital explication of germ theory, social norms, and what the modern era is really doing to our bodies and our psyches.” —Vanity Fair A preventative medicine physician and staff writer for The Atlantic explains the surprising and unintended effects of our hygiene practices in this informative and entertaining introduction to the new science of skin microbes and probiotics. Keeping skin healthy is a booming industry, and yet it seems like almost no one agrees on what actually works. Confusing messages from health authorities and ineffective treatments have left many people desperate for reliable solutions. An enormous alternative industry is filling the void, selling products that are often of questionable safety and totally unknown effectiveness. In Clean, doctor and journalist James Hamblin explores how we got here, examining the science and culture of how we care for our skin today. He talks to dermatologists, microbiologists, allergists, immunologists, aestheticians, bar-soap enthusiasts, venture capitalists, Amish people, theologians, and straight-up scam artists, trying to figure out what it really means to be clean. He even experiments with giving up showers entirely, and discovers that he is not alone. Along the way, he realizes that most of our standards of cleanliness are less related to health than most people think. A major part of the picture has been missing: a little-known ecosystem known as the skin microbiome—the trillions of microbes that live on our skin and in our pores. These microbes are not dangerous; they’re more like an outer layer of skin that no one knew we had, and they influence everything from acne, eczema, and dry skin, to how we smell. The new goal of skin care will be to cultivate a healthy biome—and to embrace the meaning of “clean” in the natural sense. This can mean doing much less, saving time, money, energy, water, and plastic bottles in the process. Lucid, accessible, and deeply researched, Clean explores the ongoing, radical change in the way we think about our skin, introducing readers to the emerging science that will be at the forefront of health and wellness conversations in coming years.

What, exactly, do you know about your body? Do you know how your immune system works? Or what your pancreas does? Or the myriad -- and often simple -- ways you can improve the way your body functions? This full-color, visually rich guide answers these questions and more. Matthew MacDonald, noted author of Your Brain: The Missing Manual, takes you on a fascinating tour of your body from the outside in, beginning with your skin and progressing to your vital organs. You'll look at the quirks, curiosities, and shortcomings we've all learned to live with, and pick up just enough biology to understand how your body works. You'll learn: That you shed skin more frequently than snakes do Why the number of fat cells you have rarely changes, no matter how much you diet or exercise -- they simply get bigger or smaller How you can measure and control fat That your hair is made from the same stuff as horses' hooves That you use only a small amount of the oxygen you inhale Why blood pressure is a more important health measure than heart rate -- with four ways to lower dangerously high blood pressure Why our bodies crave foods that make us fat How to use heart rate to shape an optimal workout session -- one that's neither too easy nor too strenuous Why a tongue with just half a dozen taste buds can identify thousands of flavors Why bacteria in your gut outnumbers cells in your body -- and what function they serve Why we age, and why we can't turn back the clock What happens to your body in the minutes after you die Rather than dumbed-down self-help or dense medical text, Your Body: The Missing Manual is entertaining and packed with information you can use. It's a book that may well change your life. Reader comments for Your Brain: The Missing Manual, also by author Matthew MacDonald: "Popular books on the brain are often minefields of attractive but inaccurate information. This one manages to avoid most of the hype and easy faulty generalizations while providing easy to read and digest information about the brain. It has useful tricks without the breathless hype of many popular books."-- Elizabeth Zwicky, The Usenix Magazine "...a unique guide that should be sought after by any who want to maximize what they can accomplish with their mental abilities and resources."-- James A. Cox, The Midwest Book Review - Wisconsin Bookwatch "If you can't figure out how to use your brain after reading this guide, you may want to return your brain for another."-- The Sacramento Book Review, Volume 1, Issue 2, Page 19 "It's rare to find a book on any technical subject that is as well written and readable as Your Brain: The Missing Manual. The book covers pretty much anything you may want to know about your brain, from what makes it up, through how it develops to how to mitigate the affects of aging. The book is easy reading, fact packed and highlighted notes and practical applications. So if you want to learn more about your brain, how it works, how to get the best out of it or just want to stave off the ravages of Alzheimers (see chapter ten for details of how learning helps maintain your brain) then I can't recommend this book highly enough."-- Neil Davis, Amazon.co.uk "MacDonald's writing style is perfect for this kind of guide. It remains educational without becoming overly technical or using unexplained jargon. And even though the book covers a broad scope of topics, MacDonald keeps it well organized and easy to follow. The book captures your attention with fun facts and interesting studies that any person could apply to their own understanding of human ability. It has great descriptions of the brain and its interconnected parts, as well as providing full color pictures and diagrams to offer a better explanation of what the author is talking about."-- Janica Unruh, Blogcritics Magazine
