Download or read book Dietary Reference Intakes for Vitamin C, Vitamin E, Selenium, and Carotenoids written by Institute of Medicine and published by National Academies Press. This book was released on 2000-08-27 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Ascorbate-Glutathione Pathway and Stress Tolerance in Plants by : Naser A. Anjum
Download or read book Ascorbate-Glutathione Pathway and Stress Tolerance in Plants written by Naser A. Anjum and published by Springer Science & Business Media. This book was released on 2010-08-20 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are sessile organisms that live under a constant barrage of biotic and abiotic insults. Both biotic and abiotic stress factors have been shown to affect various aspects of plant system including the acceleration in the formation of reactive oxygen species (ROS). The ascorbate (AsA)-glutathione (GSH) pathway is a key part of the network of reactions involving enzymes and metabolites with redox properties for the detoxification of ROS, and thus to avert the ROS-accrued oxidative damage in plants. The present book mainly deals with the information gained through the cross-talks and inter-relationship studies on the physiological, biochemical and molecular aspects of the cumulative response of various components of AsA-GSH pathway to stress factors and their significance in plant stress tolerance.
Book Synopsis Antioxidants in Therapy and Preventive Medicine by : Ingrid Emerit
Download or read book Antioxidants in Therapy and Preventive Medicine written by Ingrid Emerit and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twenty years ago, the enzyme superoxide dismutase which uses the superoxide radical anion as its specific substrate was reported. With this discovery was born a new scientific field, in which oxygen, necessary for aerobi c 1 ife on thi s planet, had to be cons i dered also in terms of its toxicity and stresses. This stimulated the search for knowledge of active oxygen species in biology and medicine. Superoxide and other reactive oxygen species are now implicated in many disease processes. Major advances have been achieved during these past years with respect to free radical generation and mechanisms of free radical action in causing tissue injury. In parallel, the possibil ity of influencing free radical related disease processes by antioxidant treatment was studied in various in vitro and in vivo systems. This was the unique theme of a conference organized in Paris by the Society for Free Radical Research (December 9-10, 1988) which brought together experts from basic sciences and clinicians in order to evaluate the current status of antioxidant therapy. The conference emphasized fundamental processes in antioxidant action. Among the major topics were superoxide dismutase (SOD) and low molecular weight substances with such activity, called SOD mimics. Other antioxidant enzymes were also considered. Antioxidant vitamins, in particular vitamins E and C, other naturally occurri ng antioxidants and vari ous synthet i c antioxidants were included in the presentations as there is now a rapidly developing series of compounds with potentially interesting clinical applications.

Download or read book Ascorbate written by Steve Hickey and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between vitamin C and health is controversial. Double Nobel Prize winner, Linus Pauling, argued that ascorbate could prevent or cure heart disease, stroke, cancer and infections. Conventional experts disagreed, disparaging supplements in favour of fruits and vegetables. This book presents a new model, describing the action of vitamin C in health and disease. It demonstrates conclusively that the establishment has misinterpreted the evidence, potentially resulting in epidemic levels of avoidable disease. The dynamic flow model explains the current results and points the way for future experiments. Vitamin C supplementation could eradicate many diseases. In pharmacological doses, it could cure the major killers of the industrialised world. Failure to test these ideas may condemn countless people to chronic illness and premature death.
Book Synopsis Ascorbic Acid in Plant Growth, Development and Stress Tolerance by : Mohammad Anwar Hossain
Download or read book Ascorbic Acid in Plant Growth, Development and Stress Tolerance written by Mohammad Anwar Hossain and published by Springer. This book was released on 2018-03-19 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ascorbic acid (AsA), vitamin C, is one of the most abundant water-soluble antioxidant in plants and animals. In plants AsA serves as a major redox buffer and regulates various physiological processes controlling growth, development, and stress tolerance. Recent studies on AsA homeostasis have broadened our understanding of these physiological events. At the mechanistic level, AsA has been shown to participate in numerous metabolic and cell signaling processes, and the dynamic relationship between AsA and reactive oxygen species (ROS) has been well documented. Being a major component of the ascorbate-glutathione (AsA-GSH) cycle, AsA helps to modulate oxidative stress in plants by controlling ROS detoxification alone and in co-operation with glutathione. In contrast to the single pathway responsible for AsA biosynthesis in animals, plants utilize multiple pathways to synthesize AsA, perhaps reflecting the importance of this molecule to plant health. Any fluctuations, increases or decreases, in cellular AsA levels can have profound effects on plant growth and development, as AsA is associated with the regulation of the cell cycle, redox signaling, enzyme function and defense gene expression. Although there has been significant progress made investigating the multiple roles AsA plays in stress tolerance, many aspects of AsA-mediated physiological responses require additional research if AsA metabolism is to be manipulated to enhance stress-tolerance. This book summarizes the roles of AsA that are directly or indirectly involved in the metabolic processes and physiological functions of plants. Key topics include AsA biosynthesis and metabolism, compartmentation and transport, AsA-mediated ROS detoxification, as well as AsA signaling functions in plant growth, development and responses to environmental stresses. The main objective of this volume is therefore to supply comprehensive and up-to-date information for students, scholars and scientists interested in or currently engaged in AsA research.

Download or read book New Insights on Vitamin C and Cancer written by Michael J. Gonzalez and published by Springer. This book was released on 2014-09-18 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on vitamin C and its effects on cancer is growing in popularity around the world as positive research continues to accumulate building a stronger case for its effectiveness. This concise SpringerBrief on Vitamin C and Cancer presents the latest findings on how vitamin C induces apoptosis. A high concentration of vitamin C allows for ascorbate to generate hydrogen peroxide in tissue that can selectively kill cancer cells. Research has confirmed that high-dose vitamin C is cytotoxic to a wide variety of cancer cell lines, and that it also boosts the anti-cancer activity of several common chemotherapy drugs. Vitamin C also does more than just kill cancer cells. It boosts immunity by stimulating collagen formation to help the body wall off the tumor. It inhibits hyaluronidase, an enzyme that tumors use to metastasize and invade other organs throughout the body. This concise and up-to-date Brief is geared towards cancer researchers and scientists, as well as physicians interested in the basic science and the translational potential of vitamin C in cancer therapeutics.

Book Synopsis Ascorbic Acid in Plants by : Yuyang Zhang
Download or read book Ascorbic Acid in Plants written by Yuyang Zhang and published by Springer Science & Business Media. This book was released on 2012-08-04 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ascorbate acid (AsA) is an important antioxidant in plants, playing important roles in various physiological processes. Humans have lost the ability to synthesize AsA because of the lack of L-gulono-1,4-lactone oxidoreductase, and thus have to absorb ascorbate from diet including fresh fruits and vegetables, as they are the major sources of ascorbate. Several pathways for AsA biosynthesis and metabolism have been identified in plants since 1998. More attention has been paid to improving ascorbate content in plants especially in fruits and vegetables. Significant progresses have been made on key enzymes and genes involved in the AsA biosynthesis and metabolism. Recently, more interests have arised in the regulation of AsA biosynthesis, as it is constantly regulated by the plant development and the environmental factors, e.g. light. Ascorbic acid is also frequently reported to affect plant growth and development e.g. flowering time and fruit ripening. The scope of the book is to cover the biological role, biosynthesis and metabolism, regulation, and metabolic modification of ascorbate in plants.

Book Synopsis Analysis of Free Radicals in Biological Systems by : A. Favier
Download or read book Analysis of Free Radicals in Biological Systems written by A. Favier and published by Birkhäuser. This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Oxidative stress" is used as the generic term describing the involve ment of reactive oxygen species in various human diseases. The scope of such a topic is becoming increasingly wide. The recent interest in radicals such as nitric oxide and the discovery of new mechanisms such as the effect of free radicals on redox sensitive proteins and genes are enlarging our understanding of the physiological role of free radicals. Oxidative stress is involved in numerous pathological. processes such as ageing, respiratory or cardiovascular diseases, cancer, neurological pathologies such as dementia or Parkinson's disease. It still remains difficult, however, to demonstrate by chemical measurement the in vivo production of free radicals and even more to realise their speciation. Therefore, the development of new tools and indicators is engrossing many researchers working in this field. Reliable indicators are abso lutely necessary not only to monitor the evolution of oxidative stress in patients but also to evaluate the efficiency of new antioxidant treat ments. The French Free radical club of Grenoble, the CERLIB has been involved for many years in the organisation of international training programs on methodology, in order to provide both theoretical and practical help to researchers from various countries. Such training sessions have been highly successful and participants value the oppor tunity to learn reliable techniques. This positive echo explains why the researchers of CERLIB decided, with the help of Prof. Dr. B. Kalyanaraman, to publish selected techniques on free radical re search.
