Antioxidants in Food

Practical Applications

 

Woodhead Publishing, 2001.

ISBNs 9781855734630

Colección: ScienceDirect

Resumen (en inglés): Antioxidants are increasingly important additives in food processing. Their traditional role is, as their name suggests, in inhibiting the development of oxidative rancidity in fat-based foods, particularly meat and dairy products and fried foods. However, more recent research has suggested a new role in inhibiting cardiovascular disease and cancer. Antioxidants in food provides a review of the functional role of antioxidants and discusses how they can be effectively exploited by the food industry.

Part one of the book looks at antioxidants and food stability with chapters on the development of oxidative rancidity in foods, methods for inhibiting oxidation and ways of measuring antioxidant activity. Part two looks at antioxidants and health, including chapters on antioxidants and cardiovascular disease, their antitumour properties and bioavailability. A major trend in the food industry, driven by consumer concerns, has been the shift from the use of synthetic to natural ingredients in food products. Part three looks at the range of natural antioxidants available to the food manufacturer. Part four of the book looks at how these natural antioxidants can be effectively exploited, covering such issues as regulation, preparation, antioxidant processing functionality and their use in a range of food products from meat and dairy products frying oils and fried products, to fruit and vegetables and cereal products.

Antioxidants in food is an essential resource for the food industry in making the best use of these important additives.

  • Provides a review of the functional role of antioxidants
  • Discusses how antioxidants can be effectively exploited by the food industry

Antioxidants in Science, Technology, Medicine and Nutrition

 

Woodhead Publishing, 1997.

ISBNs 9781898563310

Colección: ScienceDirect

Resumen (en inglés): The use of antioxidants is widespread throughout the rubber, plastics, food, oil and pharmaceutical industries. This book brings together information generated from research in quite separate fields of biochemical science and technology, and integrates it on a basis of the common mechanisms of peroxidation and antioxidant action. It applies present knowledge of antioxidants to our understanding of their role in preventing and treating common diseases, including cardiovascular disease, cancer, rheumatoid arthritis, ischemia, pancreatitis, hemochromatosis, kwashiorkor, disorders of prematurity and disease of old age. Antioxidants deactivate certain harmful effects of free radicals in the human body due to biological peroxidation, and thus prevent protection against cell damage. The book is of considerable interest to scientists working in the materials and foodstuff industries, and to researchers seeking information on the connection between diet and health, and to those developing new drugs to combat diseases associated with oxidative stress. It is important also throughout the non-medical world, especially to the work force within the affected industries.

  • Examines research in separate fields of biochemical science and technology and integrates it on a basis of the common mechanisms of peroxidation and antioxidant action
  • Applies present knowledge of antioxidants to our understanding of their role in preventing and treating common diseases, including cardiovascular disease, cancer, rheumatoid arthritis and others

Archabacteria

 

Academic Press, 1985.

ISBNs 9780123072085

Colección: ScienceDirect

Resumen (en inglés): The Bacteria, A Treatise on Structure and Function, Volume VIII: Archaebacteria is divided into three major parts and is further subdivided into several chapters. Each part deals with a specific area of study regarding archaebacteria. Part I tackles the biochemical diversity and ecology of archaebacteria, while Part II discusses translation apparatus of these organisms. The last part focuses on archaebacteria’s general molecular characteristics.
Generally, the physiological, morphological, ecological, and molecular aspects of the archaebacteria are discussed in this volume. This book also covers a historical distinction between prokaryote-eukaryote and the simultaneous development of archaebacteria.
This book is a recommended reference for biologists and scientists who are interested in the unique characteristics of archaebacteria as a very special type of bacteria. These organisms provide a “new world” for thermophilic organisms and at the same time make experts reexamine their idea of prokaryotes. Their relationship to eukaryotes leads people to believe that archaebacteria are truly a “new kingdom of organisms”.

Arctic and Tropical Arboviruses

 

Academic Press, 1979.

ISBNs 9780124297654

Colección: ScienceDirect

Resumen (en inglés): Arctic and Tropical Arboviruses contains the proceedings of the Second International Symposium on Arctic Arboviruses held at Mont Gabriel, Canada on May 26-28, 1977.
This book contains a total of 20 chapters; a few of these chapters describe the diseases with arbovirus as a possible etiological agent, such as in the case of nephropatia epidemica, rapid diagnostic techniques for the detection of arboviruses, and in vitro culture methods for arboviruses using arthropod cells. Several other chapters are devoted to the investigations on arboviruses in the northern regions and on their vectors, mosquitoes, and ticks, as well as to the detection in the north of arboviruses originally isolated inthe south. Such bipolar distribution of arboviruses could be the result of the transport of arbovirus-infected ticks by migratory birds.
This volume will provide a useful tool for all concerned with viral diseases, including virologists, epidemiologists, and ecologists.

Aspects of Sponge Biology

 

Academic Press, 1976.

ISBNs 9780123279507

Colección: ScienceDirect

Resumen (en inglés): Aspects of Sponge Biology is the result of a symposium about sponge biology held in Albany, New York in May 1975. The symposium not only presents investigations, but also problem areas in the field of sponge biology. This book therefore shows that sponges are a very challenging and untouched subject area for future studies.
This book is divided into three major parts, wherein the first part introduces and discusses sponge biology. The introduction and discussion include sponge biology principles, perspectives, and problems. The next two parts discuss cell and development biology, taxonomy, and ecology. Part 2 deals with several topics of the cellular aspect, including an analysis of reproduction in sponge populations and cytochemical studies of connective tissues in sponges. This part also looks into the cytological abnormalities in various normal and transformed cell lines. Part 3 describes the different types of sponge in their various habitats. Sponge feeding mechanisms, ecological factors controlling sponge distribution, and zoogeography of Brazilian marine Demospongiae are also discussed in this part.
This book will be of important value to biology students and teachers. Specialists including zoologists, ecologists, comparative physiologists, and biologists will also benefit from this book.

Assessment of Immune Status by the Leukocyte Adherence Inhibition Test

 

Academic Press, 1982.

ISBNs 9780126897500

Colección: ScienceDirect

Resumen (en inglés): Assessment of Immune Status by the Leukocyte Adherence Inhibition Test reviews many aspects of the immune response and cellular requirements in leukocyte adherence inhibition (LAI). It compares the LAI methodology with alternative approaches, discusses the method that has been adopted to determine whether the LAI phenomenon measures a specific immune response, and explores how these phenomena fit in with and relate to the traditional immune response.
Organized into three parts encompassing 15 chapters, this volume begins with an overview of the hemocytometer assay, the immunological basis and applications of hemocytometer LAI, the immune response as assayed by the test tube method, and the microplate assay. It then discusses cellular populations in LAI; measurements of humoral antitumor immunity; clinical application of LAI in breast cancer, prostate cancer, and rheumatic diseases; the biology of LAI and its response to human cancer; and cellular and pharmacologic aspects of LAI. It also compares microplate LAI with other in vitro assays of cell-mediated immunity, as well as tumor immunity in animal models and human cancer.
Both beginning and experienced investigators involved in all aspects of immunologic research will find this book extremely useful.

Atlas of Drosophila Morphology

Wild-type and Classical Mutants

 

Academic Press, 2013.

ISBNs 9780123846884

Colección: ScienceDirect

Resumen (en inglés):

The Atlas of Drosophila Morphology: Wild-type and Classical Mutants is the guide every Drosophila researcher wished they had when first learning genetic markers, and the tool they wish they had now as a handy reference in their lab research. Previously, scientists had only poor-quality images or sketches to work with, and then scattered resources online - but no single visual resource quickly at their fingertips when explaining markers to new members of the lab, or selecting flies to do their genetic crosses, or hybrids.

This alphabetized guide to Drosophila genetic markers lays flat in the lab for easy referencing. It contains high-resolution images of flies and the appropriate marker on the left side of each page and helpful information for the marker on the facing page, such as symbol, gene name, synonyms, chromosome location, brief informative description of the morphology, and comments on marker reliability. A companion website with updated information, useful links, and additional data provided by the authors complements this extremely valuable resource.

  • Provides an opening chapter with a well-illustrated introduction to Drosophila morphology
  • Features high-resolution illustrations, including those of the most common markers used by Drosophila researchers
  • Contains brief, practical descriptions and tips for deciphering the phenotype
  • Includes material relevant for beginners and the most experienced fly pushers

Avian Biology

Vol. 8

 

Academic Press, 1985.

ISBNs 9780122494086

Colección: ScienceDirect

Resumen (en inglés): Avian Biology,Volume VIII assesses selected aspects of avian biology. It is generally the conceptual descendant of Marshall's earlier treatise,“Biology and Comparative Physiology of Birds,” but is more than simply a revision of it.
This volume consists of two relatively lengthy, diverse chapters that focus on adaptive significance of coloniality in birds and fossil records of birds. In particular, this volume looks into group phenomena related to central place systems, that is, systems in which one or more individuals move to and from a centrally located place in the course of daily activities. It also addresses selective factors that have been suggested to explain why individuals should form colonies rather than disperse within the available foraging space.
This book will be useful as a reference material for advanced students and instructors in this field of interest.
