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 638 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.
Download or read book The Role of Selenium in Health and Disease written by Catherine Méplan and published by MDPI. This book was released on 2020-12-06 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: “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.
Download or read book Antioxidant Nutrients and Immune Functions written by Adrianne Bendich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: The detenmnation of optimal nutritional status has traditionally been based upon generalized parameters such as weight gain and body fat levels. Vitamin and mineral requirements were often related to the intakes needed to prevent overt signs of deficiency diseases such as beriberi or scurvy. However, in the past decade or so, there have been intensive investigations to determine the subtle changes in physiological functions associated with marginal micronutrient intakes. There is a growing consensus that immune system activities are very sensitive indicators of micronutrient status. During this decade, there has also been a rapid expansion of research in the role of free radicals and antioxidants in the major chronic diseases which afflict mankind( i.e. cancer, cardiovascular disease,and autoimmune disease). The main function of antioxidant nutrients in an appropriate diet is the prevention of oxidative damage to cells and their physiological functions. Antioxidant nutrients counteract free radicals and damaging oxidative actions on cell membranes. Since the cells of the immune system are rapidly differentiating and proliferating, such dividing and transforming cells are particularly susceptible to damage by oxidation. The interactions of antioxidant nutrition and immune system activities and disease resistance are therefore logical areas for research. Thus, the objective of this symposium was to bring together the leading investigators who have examined the immunological effects of dietary essential nutrients which share the capacity to act as antioxidants.

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 How Selenium Affects the Brain and Behavior written by Maia Jayne Benner and published by . This book was released on 2013 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selenium (Se) is an essential mic ronutrient and is critical for brain function. Se homeostasis within the brain remains relatively stable, however, slight fluctuations in brain Se status may have detrimental affects on brain function. Several neurological pathologies are associated with Se deficiency in humans, including mood disorders such as depression and anxiety. Se supplementation may function as a therapeutic agent for neurologic disorders through neuroprotective functions of selenoproteins, which produce the biologic effects of Se. I hypothesized that dietary Se levels would influence the Se status of the brain by changing the expression of selenoproteins, which would in turn affect anxiety behaviors. To test this hypothesis, I performed three experiments in zebrafish ( Danio rerio ) in which I altered the level of dietary Se and measured responses in anxiety-related behaviors and expression of selenoproteins in the brain. I showed that changing dietary Se status, within a nutritionally relevant range, influences anxiety-related behaviors in zebrafish. The influence of dietary Se on behavior may result from a change in brain Se status, as indicated by transcriptional changes of selenoproteins in the brain. However, if true, the transcriptional influence of selenoproteins in the brain on behavior is likely not direct. The response to Se in behavior and transcription did not follow the linear expectation of increasing Se status and decreasing anxiety-related behaviors. Instead, responses to Se depended on several variables associated with both individual zebrafish and the Se diet. Response to Se varied between zebrafish populations and sexes, with responses varying in magnitude and even direction. Additionally, the chemical form of Se, dose or Se level, and duration of Se supplementation influenced the effect of Se on behavior and transcription. Complex interactions of these variables often determined a particular endpoint's response to Se. My results suggest that a nutritional genomics approach -- one that comprehensively considers the genomic attributes of the subject population - is necessary for elucidating effects of Se on brain Se status and behavior. A greater understanding of sex and population specific Se biology is required before we can establish whether Se supplementation is beneficial for neurobehavioral disorders, such as anxiety.
