This is a Ph.D. dissertation. The skin serves as a protective interface between the body and the noxious environment. Ultraviolet (UV) radiation is one of the most important sources of environmental stress, inducing photochemical changes in the skin that may lead to sunburn, premature skin aging and skin cancer. The skin and UV also play a leading part in the vitamin D endocrine system. When UVB photons strike the epidermis, their energy can be used for the synthesis of vitamin D3. Furthermore, the skin is one of the direct target issues for vitamin D3 action. The close interplay between UV and vitamin D3 production in the skin evokes the possibility of mutual interactions. Contents: Introduction, Aims and Scopes of the Study, Materials and Methods, 1,25D3 Inhibits UVB-Induced Apoptosis and IL-6 Production in Human Keratinocytes, 1,25D3 Protects Human Keratinocytes Against UVB-Induced Damage, Two 14-EPI Analogues of 1,25D3 Protect Human Keratinocytes Against Different UVB Effects, Molecular Pathways Involved in the Anti-Apoptotic Effect of 1,25D3 in Human Keratinocytes, General Discussion and Perspectives.

The third edition is a comprehensive and updated overview of positive and negative effects of UV-exposure, with a focus on Vitamin D and skin cancer. Researchers, oncologists,and students will be provided with the most significant and timely information related to topics such as the epidemiology of skin cancer, the immune system and skin cancer, ultraviolet damage, DNA repair and Vitamin D in Nonmelanoma skin cancer and malignant melanoma. There have been a number of new, scientific findings in this fast moving field that necessitated a thoroughly updated and revised edition including new Vitamin D metabolites and skin cancer, new findings on the beneficial effects of UV and solar UV and skin cancer, adverse effects of sun protection and sunscreens, sun exposure and mortality, and more. The book will summarize essential, up-to-date information for every clinician or scientist interested in how to balance the positive and negative effects of UV‐exposure to minimize the risks of developing vitamin D deficiency and skin cancer.

Substantial data indicate the broad importance of vitamin D-based signaling in normal human physiology and the broad effects of vitamin D deficiency. Vitamin D may play a role not only in the control of bone and mineral metabolism, but also appears to be involved in immune function, cardiovascular health, thrombosis and vasculogenesis and neuromuscular function. Considerable epidemiologic data demonstrate that low vitamin D serum levels occur very commonly in normal adult populations and that vitamin D deficiency is associated with an enhanced risk of cancer death from lung, prostate, head & neck, colorectal and other gastrointestinal cancers. In addition, preclinical data provide evidence that calcitriol and other active analogues of calcitriol have anti-proliferative, pro-differentiative, pro-apoptotic and anti-angiogenic activity in numerous in-vitro and in-vivo models. It is quite clear that, while it requires high exposure to calcitriol to induce these effects, such exposure can be readily achieved when high dose intermittent therapy is given.

Vitamin D insufficiency/deficiency is a worldwide, public health problem in both developed and developing countries. Rickets among infants has reemerged. Low levels of vitamin D are associated with increased risk and mortality from cancer. At the same time, the beneficial effects of vitamin D on a host of conditions have recently been discovered. Focusing on areas not extensively covered in other comparable books, Vitamin D: Oxidative Stress, Immunity, and Aging highlights the most recent research findings on the impact of this nutrient in oxidative stress, immunity, and aging. A state-of-the-art compilation of essential information, this book explores: Vitamin D and its genomic and nongenomic effects, the role of therapeutic analogs in treating disease, and the production of vitamin D by the body The role vitamin D plays in modulating oxidative stress—with emphasis on cancer, stress-mediated diseases, photo-protection of the skin, and energy metabolism Beneficial effects of vitamin D in regulating the immune response and its importance in protecting against autoimmune, infectious, and inflammatory diseases The role vitamin D plays in the regulation of the aging process—including aspects of oxidative stress, senescence, and mortality, as well as its role in protection against cardiovascular disease and nervous system disorders This book represents an important contribution toward understanding the mechanisms by which vitamin D promotes health, increasing awareness of the importance that vitamin D plays during development, at birth, and throughout the aging process. It is a valuable reference for researchers in academia, nutrition, medicine, and industry.

Studies have clearly shown that optimal diet and nutrition can prevent skin disease. Moreover, novel nutritional components have been used experimentally to treat skin conditions. However, the clinical application of these nutrients awaits confirmation. It is thus up to health care professionals to present new knowledge in order to provide advice or treatments for skin problems. This handbook provides, in a single volume, comprehensive coverage of the relation between skin and diet and nutrition in its broadest sense. The Handbook of diet, nutrition and the skin consists of sections on general aspects of skin, nutrition and diet, micronutrients, nutraceuticals, cancer and specific skin conditions. Unique features of each chapter in this volume include relevant and useful 'key facts' which highlight interesting or important findings of the specific subjects and 'summary points' that are designed to abstract each chapter in take home messages. This handbook will be of interest to a wide range of readers, such as dermatologists, doctors, nurses and those interested in, or working within the area of skin health. This will of course also include nutritionists and dieticians, dermatologists, cosmetic scientists, health workers and practitioners, college and university lecturers and undergraduate and graduate students.

While the skeletal effects of vitamin D are well-documented, the role and importance of vitamin D outside of bone health has not been well-established. Vitamin D receptors are located in nearly every tissue of the body, and low levels of vitamin D are associated with a range of various diseases. This book provides an in-depth examination of these extraskeletal effects of vitamin D and the associations between vitamin D deficiency and various disease states. Beginning with a review of the biochemistry and physiology of vitamin D, subsequent chapters investigate its relationship to autoimmune and infectious diseases, various forms of cancer, endocrine issues such as diabetes, obesity and reproductive function, cardiovascular disease and muscle weakness. Concluding chapters discuss the role of vitamin D in neurological disorders, including Alzheimer's Disease, and cognitive function. Focusing on extraskeletal effects only across a range of conditions, Extraskeletal Effects of Vitamin D will be an important resource for clinical endocrinologists and primary care physicians.
