The Role of Ascorbic Acid in Growth, Differentiation and Metabolism of Plants
There is a paucity of information on the dynamics of Ascorbic Acid (AA) turnover in relation to germination, metabolism, growth, differentiation and development of a plant and in those undergoing stress of various types. in presowing treatment of seeds etc. The turnover of AA plays an important role during the juvenile phase of growth of a plant and has a significant bearing on its subsequent growth, development and maturation. The beneficial effect of presowing treatment of seed with Ascorbic Acid (AA) + H2 O highlights the validity of the AA-nucleic acid 2 protein metabolism concept of growth and development of plan ts. During the course of the last 30 years, work has been undertaken by the author and his collaborators on the meta bolic drifts of regulatory substances during juvenile, vegetative, reproductive and senescent phases. The most important of these growth regulatory substances was found to be Ascorbic Acid. The dynamiC role of AA turnover is revealed by its control of rates of metabolic processes as well as those of enzymic reactions which paves the way to "New Genetics".
The Biochemistry of Plants
The Biochemistry of Plants, Volume 14: Carbohydrates provides information pertinent to the fundamental aspects of plant biochemistry. This book deals with the function and structure of the plant cell wall by describing the physical and chemical properties of cell wall components. Organized into 11 chapters, this volume begins with an overview of hexose phosphate metabolism in nonphotosynthetic tissues. This text then examines the findings in fructan structures, conformations, and linkages, the enzymes involved in fructan synthesis and degradation, and their cellular regulation, location, and metabolic role in plants. Other chapters consider the methods employing enzymes to determine starch structure. This book discusses as well the different biosynthetic modes of plant cell walls. The final chapter deals with the various environmental factors that influence expression of the ?-amylase gene, suggesting how molecular biology may help in understanding carbohydrate biochemistry and the enzymes involved in carbohydrate synthesis and metabolism. This book is a valuable resource for plant biochemists.
Muscle Disease
Written by more than 60 international experts in the field, Muscle Disease embodies the explosion of new concepts and information on the pathology and genetics of muscle disease that has occurred in recent years. In order to accommodate the new complex principles involved, the book is organized around the motor unit and the inherited disorders, in particular, are centered on the ultrastructure and organelles within the muscle fiber. In this way, the wide spectrum of muscle diseases, ranging from neurogenic and inflammatory disorders to those involving defects in a single gene, can be expressed in a logical sequence. For example, disorders that principally involve specific organelles or parti...
Emergency and Continuous Exposure Guidance Levels for Selected Submarine Contaminants
U.S. Navy personnel who work on submarines are in an enclosed and isolated environment for days or weeks at a time when at sea. To protect workers from potential adverse health effects due to those conditions, the U.S. Navy has established exposure guidance levels for a number of contaminants. In this latest report in a series, the Navy asked the National Research Council (NRC) to review, and develop when necessary, exposure guidance levels for 11 contaminants. The report recommends exposure levels for hydrogen that are lower than current Navy guidelines. For all other contaminants (except for two for which there are insufficient data), recommended levels are similar to or slightly higher than those proposed by the Navy. The report finds that, overall, there is very little exposure data available on the submarine environment and echoes recommendations from earlier NRC reports to expand exposure monitoring in submarines.
Nelson Textbook of Pediatrics E-Book
Nelson Textbook of Pediatrics has been the world’s most trusted pediatrics resource for nearly 75 years. Drs. Robert Kliegman, Bonita Stanton, Richard Behrman, and two new editors—Drs. Joseph St. Geme and Nina Schor—continue to provide the most authoritative coverage of the best approaches to care. This streamlined new edition covers the latest on genetics, neurology, infectious disease, melamine poisoning, sexual identity and adolescent homosexuality, psychosis associated with epilepsy, and more. Understand the principles of therapy and which drugs and dosages to prescribe for every disease. Locate key content easily and identify clinical conditions quickly thanks to a full-color desi...
Patty's Toxicology, 6 Volume Set
Featuring the improved format used in the 5th edition, this updated set presents, in logical groupings, comprehensive toxicological data for industrial compounds, including CAS numbers, physical and chemical properties, exposure limits, and biological tolerance values for occupational exposures, making it essential for toxicologists and industrial hygienists. This edition has about 40% new authors who have brought a new and international perspective to interpreting industrial toxicology, and discusses new subjects such as nanotechnology, flavorings and the food industry, reactive chemical control to comprehensive chemical policy, metalworking fluids, and pharmaceuticals.
