Advances in Stereotactic and Functional Neurosurgery 8
The last ten years has witnessed a resurgence of interest in stereotactic surgery although this has been mainly in the field of the comparatively simple stereotactic biopsy of intracranial tumours. There is also evidence of a returning interest in functional neurosurgery other than pain which has always sustained high levels of endeavour. The present work comprises selected papers from a much larger group of interesting and important communications to the European Society for Stereotactic and Functional Neurosurgery. They represent modern views on a wide variety of stereotactic surgical topics from internationally acclaimed experts in this field. The neurosurgeon who has little or no acquain...
Carotenoids
With the number of natural carotenoid structures reported rising above 700, there is a clear need for a single reference work containing data on all these compounds. This Handbook includes all natural carotenoids and common isolation artefacts for which structures have been assigned up to the end of 2001. For each compound, it provides selected key references and critically assessed information about natural occurrence and isolation, and spectroscopic data for identification. A standard full-page entry is given for each compound that has been characterised unambiguously, showing - Common name - IUPAC name - Structure, including stereochemistry, when assigned - Spectroscopic data: UV/Vis (with illustration); MS; CD; NMR (type and references) - Chemical synthesis (references) - Natural sources and outline of isolation procedure - Remarks, e.g. further spectroscopic data, stability, properties, derivatives - Selected key references
Carotenoids
In the mid-1960's, scientists working on carotenoids throughout the World agreed to have periodic meetings for the purpose of discussing and disseminating scientific research results concerning all aspects of carotenoids. The meetings were also organized to act as teaching forums for students, and the major scientific results from each meeting were to result in a publication. Each meeting was planned to be International in scope, being held in different locations in the World, and organized by local, recognized carotenoid scientists. The first of the Carotenoid meetings was held in Trondheim, Norway in 1966. Meetings then followed in Las Cuces, New Mexico (1969); Cluj, Roumania (1972); Berne...

The Biochemistry of the Carotenoids
The carotenoids are not only amongst the most widespread of the naturally occurring groups of pigments, but probably also have the most varied functions; witness their known roles in photokinetic responses of plants, in phototropic responses of fish and as vitamin A precursors in mammals and birds. Pigments with such wide distribution and such diverse functions are obviously of great interest to biological scientists with very different specializa tions, especially as it is unlikely that the study of the functions of carotenoids is anywhere near complete. The primary aim of the present work is to discuss the distribution, bio genesis and function of the carotenoids throughout the plant and a...
Marine Natural Products Chemistry
This volume contains the lectures presented at the NATO sponsored conference on "Marine Natural Products" held in Jersey, Channel Islands, U. K., October 12-17, 1976. The intent of the organising committee was to encourage a dialogue between organic chemists who study the metabolites of marine organisms and biolo gists, ecologists, and pharmacologists who study the effects of these metabolites on other organisms. A feature of the conference was the three workshop sessions on chemotaxonomy, applications of marine natural products, and chemical communication. The papers presented at the conference contain a mixture of original research in marine natural products and reviews of some of the more important subjects. The biologists were asked to present papers which could initiate new directions for marine natural products research. Their contributions to the meeting were warmly received by the chemists in the audience. We hope that this volume contains not only past and present research but a suggestion of future research trends. The conference was first suggested by Dr. E. D. Goldberg. The organising committee, Drs. G. Blunden, D. J. Faulkner, W.

Carotenoids as Colorants and Vitamin A Precursors
Carotenoids as Colorants and Vitamin A Precursors: Technological and Nutritional Applications presents the application of carotenoids to food and to the feed of animals, poultry, fish, and birds. This book discusses the use of carotenoids in medicine, in the coloring of cosmetic and pharmaceutical products, and their unique role as photoconductors. Organized into 10 chapters, this book begins with an overview of the growing preference for natural-type colors in countries around the world. This text then examines the potential level of use of various carotenoids in a variety of foods. Other chapters consider the types of carotenoids that are added to the diet of aquatic animals, which should be selected according to the species because of varying biosynthetic capabilities and expected final pigment content. This book discusses as well the mechanisms that control the assimilation and absorption of some carotenoids. The final chapter deals with determination of vitamin A value. This book is a valuable resource for industrial chemists and aquaculturists.
