Download or read book Selenium written by Dolph L. Hatfield and published by Springer Science & Business Media. This book was released on 2001 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Mineral Containing Proteins written by Guanghua Zhao and published by Springer. This book was released on 2017-03-03 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the structure, function and nutritional values of iron-, zinc-, selenium- and calcium-containing proteins, exploring key mineral-containing proteins like phytoferritin and lactoferrin, as well as a host of zinc- and selenium-containing proteins. Due to their role in numerous metabolic processes, minerals such as calcium, iron, zinc and selenium are vital, and have to be obtained from a balanced diet because they cannot be synthesized. The structure and function of mineral-containing proteins influences the absorption of these essential minerals. As such, the study of these proteins is crucial for the assessment and maintenance of a balanced diet and for the development of effective mineral supplements. The book’s closing chapters focus on issues arising from current food processing techniques and in the development of mineral supplements. The book offers a valuable guide for researchers and students in the fields of food chemistry and nutrition.

Download or read book Selenium in Biology and Medicine written by Albrecht Wendel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: In July, 1988, more than 300 scientists from 29 different countries gathered at Tiibingen, W. Germany, in order to spend 4 days discussing their favourite trace element, selenium. This meeting continued the good tradition of three previous meetings held in Corvallis/Oregon, 1976, in Lubbock/Texas, 1980, and in Beijing/China, in 1984. Incidentally, the University of Tiibingen provided a unique historical background for a Symposium devoted to recent advances in biochemistry, pharmacology, human nutrition and human health; here, the first independent depart ment of Physiological Chemistry in Germany was founded in 1845. Pro fessor H9Ppe-Seyler elucidated here the hemin structure and his student Friedrich Miescher discovered the nucleic acids. This book contains one-half of the oral or poster presentations which were selected before the meeting was held on the basis of a one page abstract. It is the reader who will have to decide whether this time consuming policy of quality assessment was warranted or not.

Download or read book Selenium Contamination in Water written by Pooja Devi and published by John Wiley & Sons. This book was released on 2021-05-12 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: The contamination of environment and water resources by Selenium (Se) and its oxyanions from various sources are emerging contaminants of significant health and environmental concern. The primary sources include agricultural drainage water, mine drainage, residues from fossil fuels, thermoelectric power plants, oil refineries, and metal ores. Various methods and technologies have been developed which focus on the treatment of selenium-containing waters and wastewater. High concentrations of selenium in water cause various adverse impact to human health, such as carcinogenic, genotoxic, and cytotoxic effects. But in the lower concentrations, it is a useful constituent of the biological system. The range between toxicity and deficiency of selenium is minimal (40 to 400 μg per day), due to its dual nature. Selenium Contamination in Water contains the latest status and information on selenium’s origin, its chemistry and its toxicity to humans. The book represents a comprehensive and advanced reference book for students, researchers, practitioners, and policymakers in working in the field of metalloids, in particular selenium. A special emphasis is given on its geological distribution, monitoring techniques, and remedial technologies. As such, the authors critically analyze the various techniques used for the monitoring and removal of selenium from water. Featuring chapters arranged according to the major themes of the latest research, with specific case-studies from industrial experiences of selenium detection and removal, Selenium Contamination in Water will be particularly valued by researchers, practitioners, and policymakers in working in the field of metalloids including selenium.

Download or read book Selenium written by Dolph L. Hatfield and published by Springer. This book was released on 2016-09-15 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the current edition, Selenium: Its Molecular Biology and Role in Human Health expands extensively on the previous editions providing readers with the most significant advances in the rapidly developing selenium field. Evidence from epidemiology and veterinary science supports the essential role of selenium in (human) health, but its split personality in both preventing and supporting cancer and also in promoting insulin resistance has become more clearly defined. The pivotal role of glutathione peroxidase 4 in a new process of programmed cell death, ferroptosis, brings new impetus to the field. Recently defined mutations in selenoprotein and biosynthesis factor genes have been identified in patients, and the resulting disorders further emphasize the significance of selenoproteins in human health. The mechanism of selenoprotein biosynthesis, the functions of selenoproteins, and the roles of dietary selenium have been further elucidated, and new regulatory mechanisms involving selenoproteins discovered. The book, therefore, covers the breadth of current selenium research. With up-to-date chapters written by leaders in their fields, it serves as an invaluable resource for novices as well as specialists.
