      Contemporary Problems in Plant Anatomy contains the proceedings of a plant anatomy symposium that took place at Duke University and The University of North Carolina at Chapel Hill in 1983. The symposium addressed challenges in four basic research areas in contemporary plant anatomy: leaf development, floral development, differentiation of cells and tissues, and systematic and ecological anatomy. The book highlights new techniques and approaches for dealing with problems in each of these areas. Organized into 12 chapters, this volume begins with an overview of the stem-conducting tissues in monocotyledons; the development of vascular tissue patterns in the shoot apex of ferns; the role of subsidiary trace bundles in stem and leaf development of the dicotyledoneae; and the structure of phloem. It then discusses the cellular parameters of leaf morphogenesis in maize and tobacco; alternative modes of organogenesis in higher plants; morphological aspects of leaf development in ferns and angiosperms; the origin of symmetry in flowers; and intraspecific floral variation. The reader is also introduced to structural correlations among wood, leaves, and plant habit; relationships between structure and function in trees; and the development of inflorescence, androecium, and gynoecium with reference to palms. This book is a valuable source of information for plant anatomists.

      Glycoconjugate Research, Volume I contains the proceedings of the Fourth International Symposium on Glycoconjugates, held in Woods Hole, Massachusetts, in September 1977. Contributors focus on the state of knowledge in the field of glycoconjugates ranging from polysaccharides and glycoproteins to glycolipids, proteoglycans, and all their varieties in plants, animals, and microorganisms. This text is organized into three sections and consists of 87 chapters. After an introductory chapter where the use of glycosidases for the structural analysis of complex carbohydrates is described, the discussion turns to other methods used for elucidating the structure of complex carbohydrates. The chapters that follow focus on the primary structure and conformation of glycans that are N-glycosically linked to peptide chains; isolation of monofuco-disialogang... from human and bovine brains; and partial chemical characterization of activated peptides isolated from a single cell suspension of rat colonic secretory cells. The last two sections explore cartilage proteoglycans and the structure-function relationships of glycoconjugates, touching on topics such as link proteins; the biochemical aspects of malignancy in human chondrosarcomas; defensive response of plants to a microbial oligosaccharide with a pheromone-like activity; and the interaction of saccharides with ricin. This book is intended for students and practitioners of chemistry and biochemistry; biology and microbiology; and physiology.

      Lipids and Biomembranes of Eukaryotic Microorganisms synthesizes the state of knowledge for eukaryotic microorganisms and relates this knowledge to microbial membranes. This book examines each of the major classes of lipids—sterols, fatty acids, phospholipids, and sulfolipids—separate... In each case an attempt has been made to provide a comprehensive summary and to evaluate critically the literature on the occurrence and biosynthesis of these compounds in yeasts, fungi, algae, and protozoa. Physiological functions of these lipids, particularly their role in the membranes of the organisms, are described. In some cases attention has been called to the possible usefulness of lipids as taxonomic criteria. Experimental systems for studying the relation between the structure of lipids and their function in biomembranes are also discussed. These systems include the photosynthetic membranes in organisms such as Euglena, Chlorella, and Chlamydomonas in which the formation of the chloroplasts is susceptible to experimental control; and fatty acid auxotrophic mutants of yeasts and Neurospora in which the fatty acid composition of the membrane lipids can be altered by the experimenter. This book will be of use to lipid biochemists, microbial physiologists, taxonomists, and cell biologists who are interested in the molecular aspects of biomembranes.

      Plasma Protein Metabolism: Regulation of Synthesis, Distribution, and Degradation covers the concepts concerning the physiological and pathophysiological factors regulating the distribution, degradation, and synthesis of plasma proteins. This book is organized into nine parts encompassing 32 chapters. The first parts present the assumptions and methodology involved in the various in vivo and in vitro techniques that provide insights to protein metabolism. The next parts describe the techniques of protein isolation, characterization, labeling, and mathematical analysis of the data, as well as the methods for directly quantitating protein synthetic rates in nonsteady state conditions. Other parts are devoted to the factors involved in regulating the serum levels of albumin, acute phase reactants, immunoglobulins, clotting factors, complement and hormone-binding proteins. The controlling factors include such general and specific physiological regulators of protein synthesis and catabolism as levels of specific serum proteins, hormonal regulators, variations of temperature and oncotic pressure, antigenic stimulation, and nutritional factors. The remaining parts analyze the pathophysiological factors including disorders of protein synthesis, distribution, exogenous catabolism, and external loss and stress that produce abnormal levels of serum proteins. This book is intended primarily intended to protein chemists and researchers.

      Water Deficits and Plant Growth, Volume VII: Additional Woody Crop Plants is an extension of Volume VI of this treatise and deals primarily with water relations of woody crop plants in a community context. Organized into five chapters, this book begins with the important problem of predicting effects of vegetation changes on transpiration and evaporation. Separate chapters follow that discuss water relations of cotton, small fruits, grapevines, and peach trees and orchards. For each of these plant communities, emphasis is placed on hydrological cycles; water use and transpiration; absorption of water; and effects of environmental factors on soil and plant water balance. The effects of water deficits on physiological processes; vegetative and reproductive growth; yield of harvested products; drought resistance; and cultural practices affecting plant water balance and yield are also emphasized in this book. This volume will be useful to both researchers and those involved in the practice of growing woody plants for crops or for esthetic values.

      In recent years, a number of academic and commercial software packages and databases have been developed for the analysis and screening of biological data; however, the usability of these data is compromised by so-called novel genes to which no biological function is assigned. Annotating new genes outlines an approach to the analysis of evolutionary-conserv... heart-enriched genes with unknown functions, offering a step-by-step description of the procedure from screening to validation. The book begins by offering an introduction to the databases and software available, before moving on to cover programming guidelines, including a specific case study on the use of C-It for in silico screening. The second half of the book offers a step-by-step guide to experimental validation concepts and procedures, as well as an overview of additional potential applications of this approach in the field of stem cells and tissue regeneration, before a concluding chapter summarises the concepts and theories presented.

      Beaucoup de progrès scientifiques ont été réalisés en toxicologie hospitalière clinique et médico-légale, tout comme l'interprétation des résultats obtenus lors des investigations toxicologiques est devenue plus complexe. Cette nouvelle édition fait le point sur les aspects généraux et analytiques de la toxicologie médico-judiciaire incluant le devenir des xénobiotiques dans l'organisme, le recueil des échantillons, leur analyse, certaines matrices alternatives (salive, cheveu) et des monographies sur l'alcool, les stupéfiants, les produits de substitution et les nouvelles drogues émergentes. Des thèmes plus spécifiques, tels que la soumission chimique, le diagnostique de noyade, les armes chimiques, la pharmaco-toxico-géné... ou encore toxicologie et internet ont été ajoutés. Cet ouvrage sera très utile aussi bien pour les débutants que pour les toxicologues chevronnés qui ne peuvent pas être au courant de tous les détails de notre discipline. De plus, ce livre sera utile aux enseignants et aux étudiants en toxicologie, qui peuvent ainsi avoir accès d'une façon simple à des données rassemblées par des spécialistes de haut niveau et ayant une expérience professionnelle approfondie. Il en va de même pour les médecins légistes, les médecins du travail, les juristes et magistrats ou toute autre personne qui souhaite se maintenir informé des moyens à la disposition d'une science biomédicale moderne.
