The Role of Selenium in Health and Disease


Book Description

“Role of selenium in health and disease”. This book contains ten articles covering recent advances in our understanding of the relationship between the essential micronutrient selenium and human health and disease. Taken together, these articles strengthen the evidence showing that selenium, as a constituent of selenoproteins, is central to biological stress responses and mechanisms commonly altered in most complex disorders. Relevant to public health concerns, this book also emphasizes the U-shaped dose-response relationship between selenium concentration and disease risk across diverse populations from Europe [articles 2,3,6], the Middle East and North Africa [9], and Taiwan [5]. This highlights the importance of personalized nutrition strategies targeted at individuals with increased risk of disease and low selenium intake. The mechanisms by which selenium status, selenoprotein expression, and inherited genetic variations in the selenium pathway interact to affect molecular pathways involved in disease development are explored in human cohorts [2,3,5-7], and in animal [4] and in vitro models [8]. Furthermore, some reports identified novel potential biomarkers of disease risk and prognosis within the selenium pathway that could further our understanding of many chronic diseases [2,3]. Overall, this book broadens our understanding of the role of selenium in chronic diseases, and provides new directions for future preventative approaches.

Dietary Reference Intakes for Vitamin C, Vitamin E, Selenium, and Carotenoids


Book Description

This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.




Diet and Health


Book Description

Diet and Health examines the many complex issues concerning diet and its role in increasing or decreasing the risk of chronic disease. It proposes dietary recommendations for reducing the risk of the major diseases and causes of death today: atherosclerotic cardiovascular diseases (including heart attack and stroke), cancer, high blood pressure, obesity, osteoporosis, diabetes mellitus, liver disease, and dental caries.




Selenium


Book Description

This book summarizes the fast-growing and current knowledge about selenium interaction with cancer, diabetes, neuro-degeneration, heart disease, muscle disorders, HIV and several more. A special focus will be placed on in-depth knowledge about gene expression, selenoprotein biosynthesis, seleno-metabolism--as well as the molecular pathways, physiological roles, and the molecular action of selenium including interaction with other elements and vitamins or as Se-nanoparticles. The reader will receive the newest information regarding redox status and redox regulatory systems, specifically in relation to different glutathione peroxidases and thioredoxin-reductases as well as about cellular bioavailability and cytotoxicity, de-balanced immune response, inflammation or dietary aspects.




Selenium


Book Description

As discussed in this book, a large body of evidence indicates that selenium is a cancer chemopreventive agent. Further evidence points to a role of this element in reducing viral expression, in preventing heart disease, and other cardiovascular and muscle disorders, and in delaying the progression of AIDS in HIV infected patients. Selenium may also have a role in mammalian development, in male fertility, in immune function and in slowing the aging process. The mechanism by which selenium exerts its beneficial effects on health may be through selenium-containing proteins. Selenium is incorporated into protein as the amino acid selenocysteine. Selenocysteine utilizes a specific tRNA, a specific elongation factor, a specific set of signals, and the codeword, UGA, for its cotranslational insertion into protein. It is indeed the 21st naturally occurring amino acid to be incorporated into protein and marks the first and only expansion of the genetic code since the code was deciphered in the mid 1960s.

Trace Elements and Minerals in Health and Longevity


Book Description

This book describes the role of trace elements in health and longevity, pursuing a biogerontological approach. It offers essential information on the impact of trace elements on molecular and physiological processes of aging, and on their impact on health in connection with aging. The major topics covered in its 11 chapters, each dedicated to a specific trace element or mineral, are: a) Role of the element in species longevity, b) Recommended intake for longevity in animal species and in the elderly, c) Deficiency and age-related disease, d) Excess/toxicity and age-related disease, and e) Interactions with drugs prescribed in the elderly. Clinical, animal and other laboratory models of interest in aging are included, which enable a more in-depth analysis to be made. The respective chapters are a mixture of overviews and more in-depth reviews in which the mechanisms of aging are described from the point of view of their specific interactions with trace elements and minerals.




Selenium in Biology and Human Health


Book Description

Selenium plays a fascinating and still poorly understood role in the function of living cells and therefore in human health. Starting with investigations over 60 years ago into its role as a toxic agent in livestock disease, selenium studies have progressed rapidly with the application of tools from immunology and molecular biology. Selenium is now known to be important in human and animal nutrition, has been discovered as a structural component of so-called selenoproteins, and may play a number of physiological roles, ranging from cancer protection to hormone metabolism. Selenium in Biology and Human Health presents research syntheses on a range of topics involving selenium, written by specialists from around the world. It will be of interest to cell biologists and physiologists, nutritional scientists, and animal health researchers.
