Download or read book Development of Sea Urchins Ascidians and Other Invertebrate Deuterostomes Experimental Approaches written by Charles A. Ettensohn and published by Gulf Professional Publishing. This book was released on 2004-10-22 with total page 948 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a practical guide to experimental methods for studying the development of invertebrate deuterostomes, such as sea urchins, ascidians, hemichordates, and amphioxus. These model organisms are of contemporary and historical importance to the study of developmental biology, particularly genomic research. The chapters provide detailed experimental protocols that cover a broad range of topics in modern experimental methods. Topics covered range from rearing embryos to the care of adult animals, while also presenting the basic experimental methods including light and electron microscopy, used to study gene expression, transgenics, reverse genetics, and genomic approaches. * Covers a wide range of methods, from classical embryology through modern genomics * Discusses animals related to vertebrates, providing a valuable evolutionary perspective * Includes a practical guide to the use of sea urchins in the teaching laboratory
Download or read book The Sea Urchin Embryo written by G. Czihak and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 719 pages. 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.

Download or read book Fundamentals Of Aquatic Toxicology written by Gary M. Rand and published by CRC Press. This book was released on 2020-08-06 with total page 1152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is divided into three parts. The first part describes basic toxicological concepts and methodologies used in aquatic toxicity testing, including the philosophies underlying testing strategies now required to meet and support regulatory standards. The second part of the book discusses various factors that affect transport, transformation, ultimate distribution, and accumulation of chemicals in the aquatic environment, along with the use of modelling to predict fate.; The final section of the book reviews types of effects or endpoints evaluated in field studies and the use of structure-activity relationships in aquatic toxicology to predict biological activity and physio-chemical properties of a chemical. This section also contains an extensive background of environmental legislation in the USA and within the European Community, and an introduction to hazard/risk assessment with case studies.
Download or read book The Sea Urchin Embryo written by G. Giudice and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 250 pages. 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 Urchin Mitosis in High Magnetic Fields written by Vernon R. Reno and published by . This book was released on 1966 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mitosis in sea urchin eggs was retarded following their exposure to magnetic fields higher than 70,000 gauss which had gradients greater than 4200 gauss/centimeter. The degree of retardation was correlated simultaneously to both the field strength and the field gradient. Division delay in fields ranging from 100,000 to a maximum of 120,000 gauss was independent of the gradient. Differences in division delay were found which may be a reflection of the differential migration of oxygen and nitrogen due to their para- and diamagnetic properties. An hypothesis is given concerning the biochemical processes affected by magnetic fields. (Author).
Download or read book Biology of Fertilization V3 written by Charles Metz and published by Elsevier. This book was released on 2012-12-02 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fertilization Response of the Egg is the third and final volume of the Biology of Fertilization which provides a detailed discussion of the responses of the egg to the fertilizing sperm, collectively called as the activation of the egg. It is an anthology of physiological articles written by biology and physiology professionals. The book is divided into 12 chapters, half of which focused on the sea urchin egg fertilization, as it is the most studied form. The first two chapters cover the discussions on the first visible egg responses to fertilization and the formation of the fertilization membrane. The following chapter describes the relationship of sperm entry into the amphibian egg and the establishment of the symmetry of the embryo. Other chapters focus on the electrical and ionic changes of the egg plasma membrane and cytoplasm. The remaining parts of the book describe the synthetic activities in the egg that are initiated during fertilization. These include description of DNA and maternal RNA syntheses, nuclear-cytoplasm interactions, protein synthesis during oogenesis and early embryogenesis, and the expression of maternal messenger RNA. The book is an excellent reference for undergraduate and graduate biology students, specifically in physiology, embryogenesis, and developmental biology. It can also be an invaluable source of information for lecturers and professionals in biology.
Download or read book Reproduction and Development of Marine Invertebrates of the Northern Pacific Coast written by Megumi F. Strathmann and published by University of Washington Press. This book was released on 2017-10-01 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference work is designed to provide background information on an array of northeastern Pacific marine invertebrate species so that they can be more easily included in comparative studies of morphology, cell biology, reproduction, embryology, larval biology, and ecology. It is meant to serve biologists who are new to the field as well as experienced investigators who may not be familiar with the invertebrate fauna of the northern Pacific Coast. The species discussed in this volume are mostly from the cold temperate waters of the San Juan Archipelago, near Puget SOund and the Strait of Georgia, but the information and methods given will be useful in laboratories from Alaska to central California and applicable to some extend in other coastal or inland facilities. An introductory chapter discusses basic prodcedures for collecting and maintaining mature specimens, for initiating spawning, and for culturing embryos and larvae in the laboratory. Subsequent chapters summarize reproduction and development in thirty different invertebrate groups and provided ercent references through which additional information can be traced, cite monographs or keys needed to identify species, and give methods useful for studying an array of selected species. Available information on habitat, diet, reproductive mode, egg size, developmental pattern, developmental times, larval type, and conditions for settlement and metamorphosis is reported for over 450 species.

Download or read book Women of Science written by Gabriele Kass-Simon and published by Indiana University Press. This book was released on 1993 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Women of Science is a collection of essays dealing with contributions women have made to various scientific disciplines, written by women scientists in those disciplines. The areas covered are: astronomy, archaeology, biology, chemistry, crystallography, engineering, geology, mathematics, medicine, and physics. The women who have written these essays are, for the most part, not professional historians, but rather scientific professionals who felt the necessity of researching the contributions women have made to the devlopment of their fields. The essays are unique, not only because they recover lost women who made significant contributions to their disciplines, but also because they are written with a depth of understanding that only a scientist working in a specific area can have. The essays will be of interest not only to students (especially women students) of science who may be unaware of the many contributions women have made, but also to readers of the history of science whoses texts more often than not fail to include the work of most women scientists.
