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.
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.
Bioactive Egg Compounds presents the latest results and concepts in the biotechnological use of egg compounds. Following an introduction to the different compounds of egg white, yolk and shell, the nutritive value of egg compounds is discussed. The text describes procedures for processing egg compounds to improve their nutritive value, including so-called enriched eggs. Also described is the isolation and application of egg compounds with special properties, such as antibiotic action.
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.
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.
This book presents a cutting-edge, in-depth investigation into new methods of health promotion. It is one of the first books to focus on the role of omega-3 polyunsaturated fatty acids in unhealthy diets. The book also contains reviews of the economic benefits of novel health promotion and disease prevention methods. Leading experts present recent examples and clinical trials.
The Pigments from Microalgae Handbook presents the current state of knowledge on pigment production using microalgae-based processes, and covers both the scientific fundamentals of this technology and its practical applications. It addresses biology, chemistry, biochemistry, analysis and engineering aspects, as well as applications of natural pigments in photosynthetic organisms. The book also describes the analytical procedures associated with the characterization of pigments and the engineering aspects of microalgal pigment production. It considers the three major classes of pigments(chlorophylls, carotenoids and phycobiliproteins) produced and surveys the main commercial applications of these chemicals. The book offers a valuable source of information for industrial researchers and practitioners in industrial biotechnology, as it covers various engineering aspects of microalgal pigment production, such as bioreactors and bioprocesses, industrial extraction processes, and the bioeconomy of production including life-cycle assessment. The book will also be of interest to undergraduate and graduate students of biochemistry, food chemistry, and industrial microbiology.
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.
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.
The Nutrition and Health series of books have had great success because each volume has the consistent overriding mission of providing health professionals with texts that are essential because each includes (1) a synthesis of the state of the science, (2) timely, in-depth reviews by the leading researchers in their respective ?elds, (3) extensive, up-to-date fully annotated ref- ence lists, (4) a detailed index, (5) relevant tables and ?gures, (6) identi?cation of paradigm shifts and the consequences, (7) virtually no overlap of information between chapters, but targeted, inter-chapter referrals, (8) suggestions of areas for future research, and (9) balanced, data-driven answers to patient ...
