Selenium in Nutrition and Health
This book provides information about selenium as an important part of integrated antioxidant systems in animal and human bodies responsible for maintaining health. It contains practical advice in relation to effective usage of selenium supplements, including optimal forms and doses. It also combines fundamental information on selenium biochemistry and metabolism. It also presents the most recent findings, unresolved puzzles and future directions for selenium research. In recent years, natural antioxidants have received tremendous attention in relation to human health and food quality. However, the scientific background of many health-promoting claims for natural antioxidants is not always understandable for the general public and needs further clarification. Furthermore, agricultural applications of antioxidants await further investigation.
Selenium in Poultry Nutrition and Health
The goal of this book is to provide up to date information about the roles of Se in poultry nutrition and health. A special emphasis is given to the role of selenium as an essential part of the integrated antioxidant system. Se in feed and organic Se are characterised in detail with emphasis to selenomethionine as a storage form of Se in the body. Also specific Se-deficiency related diseases in poultry are described and the importance of Se in growth, development, immunity and reproduction is demonstrated. A link between poultry industry and human health via production of Se-eggs and Se-enriched meat is shown.
Selenium in Pig Nutrition and Health
The goal of this book is to provide up to date information about the roles of Se in pig nutrition and health. Specific Se-deficiency related disorders in pigs are also described, and the importance of Se in growth, development, immunity and reproduction is demonstrated. Molecular mechanisms of protective effects of Se under stressful conditions of commercial pig production are characterised.
Selenium in ruminant nutrition and health
Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in humans and farm animals through its incorporation into a range of selenoproteins. Low Se content in main feed ingredients is a common problem worldwide and dietary Se supplementation is a current practice in ruminant nutrition. Recent research clearly proved that sodium selenite, used for the last 50 years as a feed supplement, is not an optimal form of Se. However, use of organic selenium in dairy and beef diets can help meet Se requirement and maintain health/high immunocompetence, productive and reproductive performance. The goal of this book is to provide up-to-date i...
Natural Antioxidants in Avian Nutrition and Reproduction
The main aim of this volume is to provide up-to-date information about natural antioxidants in relation to avian physiology, nutrition and reproduction. A comparison with farm animals and humans is made where appropriate.
Recent Advances in Trace Elements
Comprehensive and multidisciplinary presentation of the current trends in trace elements for human, animals, plants, and the environment This reference provides the latest research into the presence, characterization, and applications of trace elements and their role in humans, animals, and plants as well as their use in developing novel, functional feeds, foods, and fertilizers. It takes an interdisciplinary approach to the subject, describing the biological and industrial applications of trace elements. It covers various topics, such as the occurrence, role, and monitoring of trace elements and their characterization, as well as applications from the preliminary research to laboratory tria...
Current advances in selenium research and applications
Selenium (Se) is an essential dietary trace element participating in the regulation of various physiological functions in both animals and humans through its incorporation into selenoproteins as the amino acid selenocysteine. Among many minerals Se has a special place being the most controversial trace element with a narrow gap between essentiality and toxicity. Indeed there are important environmental issues considering selenium as a pollutant from the one hand and global selenium deficiency on the other. In fact, Se deficiency is considered as a risk factor for the development of various diseases in human and animals. Decreased Se availability from soils as a result of low soil pH and usag...

Art as Communication
Is art a form of communication? If so, what does art express or represent? How should we interpret the meaning of works created by more than one artist? Is art an adaptation, via natural selection? In what ways is art similar to—and different from—language? Art as Communication: Aesthetics, Evolution, and Signaling employs information theory, the theory of evolution, and the newly developed sender-receiver model of communication to reason about art, aesthetic behavior, and its communicative nature. Shawn Simpson considers whether art, from a biological point of view, is the province of only humans or whether animals might reasonably be said to create art. Examining the work of evolutionary biologists, art theorists, linguists, and philosophers—including Charles Darwin, Stephen Davies, H. Paul Grice, and others—he addresses how well different theories of communication explain meaning and expression in art and argues that art is much more continuous with other forms of communication than previously thought.
Male Fertility and Lipid Metabolism
Interest in lipid metabolism and polyunsaturated fatty acids in relation to sperm production has increased during the last decade. The motivation for the research described in this book originates from the discovery that sperm lipids contain extremely high proportions of long-chain polyunsaturated fatty acids, thus establishing a link between lipid biochemistry and male fertility. Moreover, the fact that polyunsaturated fatty acids must, in some form, be supplied in the diet suggests a relationship between fertility and nutrition and raises the possibility of improving male fertility by dietary means. This book gives the reader an up-to-date view of several aspects of male fertility in relation to lipid and fatty acid metabolism. Researchers in the domain of male fertility, fatty acid metabolism, and antioxidants; medical personnel involved in the treatment of male infertility; fat technologists; students in nutrition, dietetics, biochemistry, pharmacy, and medicine; and everybody interested in the field will find this book useful.
