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 Developmental Aspects of the Cell Cycle written by Ivan Cameron and published by Elsevier. This book was released on 2012-12-02 with total page 401 pages. 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.
Download or read book Physical Modalities in Dermatologic Therapy written by H. Goldschmidt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of vital therapeutic modalities are not covered adequately in current dermatology textbooks. This book is intended to fill that gap. It originated in a series of special lectures on modem applications of physical modalities given at recent annual meetings of the American Academy of Dermatology; the main topics were radiotherapy, electrosurgery, phototherapy, cryosurgery, and related therapeutic modalities. The authors, recognized authorities in their field, have included much addi tional information which could not be covered in the original lectures because of time limitations. The indications for modem dermatological x-ray therapy reflect the basic views of the recently published guide lines of the National Academy of Sciences-National Research Council. Both text and illustrations are oriented toward the practical aspects of therapy with physical modalities. A special effort was made to bring the contributions up to date; pertinent references have been added for those who wish to pursue particular topics still further. Where there is an apparent overlap between chapters, it was felt to be advantageous because different authors approached their subject from different perspectives. I am most grateful to the various authors who generously contributed despite their many other commitments. I wish, also, to thank the staff of Springer-Verlag for their advice and assistance in the preparation of the manuscript.

Download or read book Concepts in Radiation Cell Biology written by Gary Whitson and published by Elsevier. This book was released on 2012-12-02 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts in Radiation Cell Biology summarizes current concepts related to the effects of radiation on cell biology, with emphasis on the underlying macromolecular basis for cellular changes in irradiated cells. It explores the effects of non-ionizing radiation, such as ultraviolet and visible light; the use of laser light in cellular studies; and the biological effects of ionizing radiation on cells. Results of ultraviolet studies implicating DNA as the main target macromolecule responsible for radiation injury, such as division delays, lethality, and delayed DNA replication, are presented. Divided into eight chapters, this volume begins with an overview of ultraviolet irradiation of DNA as well as the physical and biological properties of irradiated DNA. It then discusses methods used in the photoinactivation of viruses; the effects of ultraviolet radiation on bacteria; radiation-induced biochemical changes in protozoa; and techniques for the analysis of radiation-induced mitotic delay in synchronously dividing sea urchin eggs. The book also covers the effects of radiation on mammalian cells; the effects of ionizing radiation on higher plants; and the photodynamic effects of laser light on cells. This book is a valuable resource for cell biologists, as well as students and investigators who are seeking the necessary information for further experimentation in radiation cell biology.
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.
