Download or read book Developmental Biology of the Sea Urchin Embryo written by Giovanni Giudice and published by Elsevier. This book was released on 2012-12-02 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developmental Biology of the Sea Urchin Embryo discusses both structural and experimental observations on the morphological and metabolical aspects of sea urchin embryology. It is organized into two major parts, designated morphogenesis and related problems and metabolism. These parts encompass 12 chapters that cover the role of sea urchin embryology in developmental biology and the advantages and limitations of using sea urchin embryo in the study of developmental problems. The introductory chapters describe the morphogenesis, ultrastructure, and physiology of fertilization of sea urchin embryo, including the process of modification of the egg surface. A discussion on cell dissociation and reaggregation in sea urchin embryos from blastula stage is provided. The core chapters of Part II cover the activation of respiration, nucleic acid and protein synthesis, and several other enzymatic activities.

Available in PDF, EPUB and Kindle. Book excerpt: Developmental Aspects of the Cell Cycle discusses the molecular, organelle, cellular, and organismal levels of cell cycle, cell proliferation, and cell differentiation. It addresses the possible antagonism between the ability of cells to proliferate and to differentiate. After brief historical, theoretical, and methodological background information for each cell system, this book concentrates on the mechanisms involved in the regulation of cell proliferation and differentiation. The book presents systems in which mass cultures of cells can be induced to undergo a synchronous transition from one cell state to another, enabling the amplification of cellular and biochemical events to be analyzed with the available morphological and biochemical techniques. Some chapters explain the possibility of cell state production by a microenvironment that occurs at the organismal level, in which a series of mitotic and growth steps causes cells proliferation. The concluding chapters discuss cell proliferation and differentiation in specific cell system, such as embryonic chick and male germ cell. This book will appeal to investigators in many disciplines, teachers, and life sciences students, particularly, to molecular, cellular, and developmental biologists.

Available in PDF, EPUB and Kindle. Book excerpt: This book should be regarded as the continuation to my previous book Developmental Biology of the Sea Urchin Embryo, edited by the Academic Press in 1973, rather than as a new edition. Due to the exceedingly high rate of development in this field (something like 2000 papers have been published on this subject in these last 10 years), I preferred, in fact, not to describe again in detail the enormous amount of the old literature, as was attempted in my previous book, but to briefly summarize the state of the art in each problem and to describe in some detail the experiments per formed in the last 12 years. In doing so, more emphasis was given to the more recent ones and to those which can be considered as corner stones in each subject. Care was, however, taken to mention the reviews or key papers in which the reader can find a source of the details of the older literature, besides refering him to my previous book.

Download or read book Sea Urchins written by John M. Lawrence and published by Academic Press. This book was released on 2013-05-31 with total page 559 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully revised and expanded edition of Sea Urchins provides a wide-ranging understanding of the biology and ecology of this key component of the world's oceans. Coverage includes reproduction, metabolism, endocrinology, larval ecology, growth, digestion, carotenoids, disease and nutrition. Other chapters consider the ecology of individual species that are of major importance ecologically and economically, including species from Japan, New Zealand, Australia, Europe, North America, South America and Africa. In addition, six new contributions in areas such as immunology, digestive systems and community ecology inform readers on key recent developments and insights from the literature.Sea urchins are ecologically important and often greatly affect marine communities. Because they have an excellent fossil record, they are also of interest to paleontologists. Research on sea urchins has increased in recent years, stimulated first by recognition of their ecological importance and subsequently their economic importance. Scientists around the world are actively investigating their potential for aquaculture and fisheries, and their value as model systems for investigations in developmental biology continues to increase. Continues the series "Developments in Aquaculture and Fisheries Science" with a newly revised volume Collects and synthesizes the state of knowledge of sea urchin biology and ecology Expanded from previous edition to include non-edible species, providing the needed basis for broader evolutionary understanding of sea urchins

Available in PDF, EPUB and Kindle. Book excerpt: The first three chapters of Vol. 3 of Bio-organic Marine Chemistry deal with the chemistry and function of peptides. Chapter 1 by Ireland and coworkers serves as an introduction to marine-derived peptides. It is arranged phyletically and encompasses the entire range from dipeptides to a compound with 95 amino acid residues. Peptides involved in primary metabolism and hence belonging to the realm of macromolecular biochemistry are excluded. However, it might be mentioned in passing that the dividing line between large and small molecule chemistry is continually becoming less distinct. Not only are more compounds of intermediate size, from 1,000 to 10,000 dalton, being discovered, but instruments and techniques, particularly in mass spectrometry and nuclear magnetic resonance have been developed for their structural elucidation by what is considered small molecule methodology. Two groups of peptides are discussed in separate chapters. Biologists who have observed and described the mating behavior of diverse species of marine invertebrates have long surmised that a chemical mechanism might be operating in many cases of individual as well as mass fertilization. The chemical activators of sea urchin sperm prove to be a series of peptides, whose structures and activity are discussed by Suzuki.

Available in PDF, EPUB and Kindle. Book excerpt: Sea urchin eggs are objects of wonder for the student who sees them for the first time under the microscope. The formation of the fertil ization membrane after insemination, the beauty of mitotic cleavage, the elegant swimming of embryos, remain an esthetic pleasure even for the eyes of seasoned investigators. But sea urchin eggs have other, more practical, advantages: they lend themselves to surgical operation without difficulty and they heal perfectly; they can be obtained in very large amounts and represent thus an extremely favorable material for biochemists and molecular embryologists. It is not surprising that, in view of these exceptional advantages, sea urchin eggs have attracted the interest of innumerable biologists since O. HERTWIG discovered the fusion of the pronuclei (amphimixy), in Paracentrotus lividus, almost a century ago. The purpose of the present book is to present, in a complete and orderly fashion, the enormous amount of information which has been gathered, in the course of a hun dred years of sea urchin embryology. JOSEPH NEEDHAM, in 1930, was still able to present all that was known, at that time, on the biochemistry of all possible species of developing eggs and embryos in his famous "Chemical Embryology" (Cambridge University Press) . It would no longer be possible for one man to write a modern version of what was a "Bible" for the young embryologists of forty years ago.
