Download or read book Vitamin E and Ionizing Radiation written by Nelida L. Del Mastro and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin E -- a family of eight natural structurally related tocopherols and tocotrienols compounds expressed generally as a-tocopherol -- represents an essential component in human nutrition required for the preservation of lipids in stable form in biological systems and also in foods. In commonly consumed foods, vitamin E appears among the main antioxidants together with vitamins A and C and minerals like copper, zinc and selenium. The effect of gamma irradiation on the level of nutritional factors has been investigated. This book examines the study of the effects of vitamin E on the formation of end products of radiation-induced free-radicals transformation, which shows that the vitamin is able to oxidise a-hydroxyl-containing radical, yielding the respective carbonyl or to reduce them to the initial molecules.

Download or read book Vitamin E written by Matthew H. Braunstein and published by Nova Publishers. This book was released on 2006 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin E is a fat-soluble vitamin that exists in eight different forms. Each form has its own biological activity, which is the measure of potency or functional use in the body. Alpha-tocopherol (-tocopherol) is the name of the most active form of vitamin E in humans. It is also a powerful biological antioxidant. Vitamin E in supplements is usually sold as alpha-tocopheryl acetate, a form that protects its ability to function as an antioxidant. The synthetic form is labelled 'D, L' while the natural form is labelled 'D'. The synthetic form is only half as active as the natural form. Antioxidants such as vitamin E act to protect the cells against the effects of free radicals, which are potentially damaging by-products of energy metabolism. Free radicals can damage cells and may contribute to the development of cardiovascular disease and cancer. Studies are underway to determine whether vitamin E, through its ability to limit production of free radicals, might help prevent or delay the development of those chronic diseases. Vitamin E has also been shown to play a role in immune function, in DNA repair and other metabolic processes. This book presents leading research on this important topic.

Download or read book Radiotherapy of Intraocular and Orbital Tumors written by Winfried E. Alberti and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiotherapy of Intraocular and Orbital Tumors presents a new approach to the role of radiation therapy in the management of ophthalmic cancer. The indications for ultrasonography, computed tomography, and magnetic resonance imaging studies are analyzed, and treatment techniques, together with their results, are described for each tumor. Particle beam and plaque irradiation are reviewed, and conservative and surgical management of radiation effects are detailed. In the past, most books on this subject included a chapter on radiotherapy but emphasized the dangers of radiation complications. However, great progress in understanding the effects of irradiation upon the tissues of the eye and orbit, new therapeutic equipment, and new imaging techniques (CT, MRI) allow for careful treatment planning. This book has taken the long overdue step of reconsidering the role of irradiation of the eye so that it may take its place as a respected, rather than feared, treatment in the combined modality approach so important today. Together with experts in relevant fields, the editors have produced a refreshingly clear and thoroughly referenced volume which will be a valuable asset to all ophthalmologists, radiation oncologists, pediatricians, endocrinologists, oncologists, and residents in training, as well as to students in these disciplines.
Download or read book Influence of Dietary Vitamin E on Behavior of Listeria Monocytogenes and Color Stability in Ground Turkey Breast Meat Following Electron Beam Irradiation written by Maria Gabriela Romero and published by . This book was released on 2003 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is growing concern that the free radical scavenging effect of antioxidants added to meats might reduce the antimicrobial effectiveness of ionizing radiation. A study was conducted to determine the effect of vitamin E on the behavior of Listeria monocytogenes and color stability in turkey meat following electron beam irradiation. Raw ground turkey breast meat from birds fed diets containing 0 (control), 50, 100, and 200 IU of vitamin E per kg was inoculated with a 5-strain mixture of L. monocytogenes to give [difference]107 CFU/g. Inoculated samples were irradiated at 0, 0.5, 1, and 2 kGy, and stored aerobically (12 days) or under vacuum (42 days) at 4C̊. L. monocytogenes survivors were determined by plating diluted samples on Modified Oxford Medium (MOX) and counting bacterial colonies on MOX plates after 48h at 35C̊. Meat color was measured using a Hunter Lab colorimeter. Irradiation at 2.0 kGy resulted in [difference]3.5 log reduction of initial numbers of L. monocytogenes. There were no significant differences in D-values for L. monocytogenes in meat irrespective of vitamin E treatment (P>0.05). Also, vitamin E treatments did not affect growth rate of the pathogen in aerobic or vacuum-packaged samples following irradiation (P>0.05). Compared to controls, irradiated meat from birds fed 100 or 200 IU vitamin E demonstrated significant improvement in color stability (Hunter L* and a*-values) during aerobic storage (P

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.

Download or read book Vitamin E in Health and Disease written by and published by BoD – Books on Demand. This book was released on 2021-10-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin E is a group of fat-soluble compounds found in a wide variety of foods. Daily requirements of vitamin E can be met with a balanced diet. High-dose supplementation may be hazardous rather than beneficial. Vitamin E serves as an antioxidant, participates in anti-inflammatory processes, inhibits platelet aggregation, and enhances immunity. Vitamin E supplementation can be beneficial against coronary artery disease, eye disorders, cognitive decline, cancer, and skin aging. This book will mainly focus on the diverse functions of vitamin E, importance of vitamin E status to provide a healthy lifespan, and the interaction between vitamin E and several pathological conditions. Readers will receive a general overview of the importance of vitamin E in health and different pathological conditions.
