Sun Protection In Man by P.U. Giacomoni

Original Title: Sun Protection In Man

"Sun Protection in Man" looks at the beneficial and harmful effects of solar radiation. The physiological consequences of sun exposure have been systematically studied starting at the end of the nineteenth century and we now have accumulated knowledge about how Caucasian and Asian skins reacts to solar radiation. The chemical effects of solar ultraviolet radiation have been analyzed with particular emphasis during the second half of the twentieth century. Research on micro-organisms has allowed us to understand the mechanisms of UV-induced mutagenesis and photosensitization. Studies with laboratory rodents have opened the path to the understanding of UV-induced immune-depression, carcinogenesis, photo-damage and photo-aging. The results of these studies have enabled other scientists to investigate the same phenomena in human organs such as the skin and the eye. UV radiation damages hair, as well. The present knowledge in these fields is summarized in some of the chapters of this monograph. Mass phenomenon in Europe with the generalization of summer vacations which were a consequence of social reforms introducing the concept of "paid vacations". This created a need for protection and opened a market for sunscreens. This monograph is concerned with sun protection as a whole and is not just "another book on sunscreens". Nonetheless, in these days of general concern, it is important to learn about the efficiency of sunscreens. Several authors discuss how to reduce the number of impinging photons and explain why sunscreens seem to offer less protection than expected. Guidelines are given on how to use sunscreens in everyday life, which are expressed rigorously though clearly, for access to the common reader. Our knowledge on the relationship between sun and humans is at the early stages of development. Industrial and commercial activities are concerned by the development of this knowledge, and rules have been and will be promulgated to guarantee efficacy and safety of sun-products. It is hoped that this monograph will be of interest to the scholar, the layman and the legislator.

The Last Natural Man by Robert A. Norman

Original Title: The Last Natural Man

This book explores cultural evolution and the meaning of the word 'natural'. We are at the crossroads of a major transformation. Why is our current time so important in the history of man? We are at a point where we may be the last generation that is not partially or fully bionic. The last natural man: natural in what way? What is “natural”? Is it a catch phrase like “integrative” or “holistic” that transmits a certain magical warm glow? If the word “natural” was a plant, it would be beautiful, green, luxuriant, and edible.Does it mean we are the last to not replace or modify our parts? What about laser surgery? Knee or hip replacement? Botox and fillers? Chemical therapy? Or a directional chip in the brain?Do we really mean the very last natural man? Cultural evolution has been the major driving force over the last several thousand years and enormous in its influence compared to almost invisible changes in our physical adaptations. If cultural and religious evolution was the driver for human history, are we now entering the phase of physical transformation – where humanity refuses to accept mortality and seeks to make changes to defeat nature. In this book the authors are describing a paradigm shift of all of humanity—just as hunter-gatherers had their stellar features, the future man will have many attractive qualities, even if many artificial. We are often balancing on the precipice between science and science fiction, now ready to tip the scales and slide comfortably into the future of great discoveries and wonderful changes. But are these changes all for the good? What will being human mean? "A lively, superbly informed, compassionate conversation between two accomplished physician-writers about the human past and the human future, carefully grounded in the sciences of medicine and evolution. If you care about who we are and what may save us from ourselves, read this enormously informative and entertaining book." Melvin Konner, MD, PhD, author of The Tangled Wing: Biological Constraints on the Human Spirit and Women After All: Sex, Evolution, and the End of Male Supremacy

Sun Protection by Brian Diffey

Original Title: Sun Protection

Sun Protection differentiates itself from other texts by adopting a risk-management approach to determine whether, how, and in what circumstances, harm might be caused, and to explore the feasibility of various strategies in controlling exposure to solar UV radiation. This multi-disciplinary book covers topics from climatology through human exposure to sunlight, as well as biological and clinical effects of UV radiation to physical and chemical strategies for photoprotection.
