Download or read book The Ultrastructure of the Animal Cell written by L. T. Threadgold and published by Elsevier. This book was released on 2017-05-03 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ultrastructure of the Animal Cell examines the ultrastructure of the animal cell, with emphasis on the chemical, biochemical, and physiological aspects of the cell. Discussions are organized around the interphase cell and cell division and cover topics ranging from the general structure and molecular models of cell membranes to the ultrastructure of the nucleus and the cytosome. Changes in cell ultrastructure during embryogenesis, differentiation, and secretion are also considered. This monograph is divided into nine chapters and opens with an introduction to the principles and techniques of electron microscopy. The next section is about the interphase cell and first presents an overview of the animal cell before proceeding with an analysis of the ultrastructure of the nucleus and the cytosome, paying particular attention to the plasma membrane and associated structures; the hyaloplasm; endoplasmic reticulum; the Golgi complex; and mitochondria. The changes that occur in the ultrastructure of the cell during embryogenesis, differentiation, and secretion are also described. The last section focuses on cell division and the ultrastructure of the dividing cell. This text will be a useful resource for cell biologists, biochemists, and physiologists, as well as students and teachers of biology, biochemistry, and physiology.

Download or read book The Interpretation of Ultrastructure written by R. J. C. Harris and published by Academic Press. This book was released on 2014-07-15 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Interpretation of Ulstrastructure is a collection of papers dealing with techniques in ulstrastructural research such as in fixation, reversed staining, ultrastructure in embryos and in plants, control of observations by light microscopy, and cytochemistry at the electron microscope level. One paper describes various fixatives used on rat liver tissue including a standard osmium tetroxide solution, pure melted osmium tetroxide, and strong osmium tetroxide solutions in carbon tetrachloride. Another paper points out that the use of electron micrographs of the cell nucleus and chromosomes should include approaches to chromosome analysis. For the investigator studying the three dimensional organization of chromosomes, his approaches should include classical cytology and cytogenetics, chemical and cytochemical studies on nuclei, as well as chemical and physical analysis of nucleic acid and nucleoprotein molecules. Several papers discuss the study of natural and artificial DNA-plasma by thin sections, an assessment of negative staining techniques for revealing ultrastructure, and other approaches in the study of biological ultrastructure by high-resolution electron microscopy. The collection will benefit microbiologists, biotechnologists, and academicians connected with the biological sciences.

Download or read book Ultrastructure Macromolecules and Evolution written by Lawrence S. Dillon and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thus far in the history of biology, two, and only two, fundamental principles have come to light that pervade and unify the entire science-the cell theory and the concept of evolution. While it is true that recently opened fields of inves tigation have given rise to several generalizations of wide impact, such as the universality of DNA and the energetic dynamics of ecology, closer inspection reveals them to be part and parcel of either of the first two mentioned. Because in the final analysis energy can act upon an organism solely at the cellular level, its effects may be perceived basically to represent one facet of cell me tabolism. Similarly, because the DNA theory centers upon the means by which cells build proteins and reproduce themselves, it too proves to be only one more, even though an exciting, aspect of the cell theory. In fact, if the matter is given closer scrutiny, evolution itself can be viewed as being a fundamental portion of the cell concept, for its effects arise only as a consequence of changes in the cell's genetic apparatus accumulating over geological time. Or, if one wishes, the diametrically opposite standpoint may be taken. For, if current concepts of the origin of life hold any validity, the evolution of precellular organisms from the primordial biochemicals must have proceeded over many eons of time prior to the advent of even the most primitive cell.
Download or read book Atlas of Human Cell Ultrastructure written by A. Henry Sathananthan and published by Professor Arunachalam Henry Sathananthan . This book was released on 1996 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: This EBook covers the fine structure of human cells and tissues as seen with the transmission and scanning electron microscope (TEM & SEM). To the author’s knowledge there is no book of this kind expressly devoted to human cells and tissues. The book is concise and is primarily intended to help in the teaching of microanatomy to first-year medical and health-science students, paramedical students and first-year science and other university students. It can also be used to teach university entrance students in secondary schools and technical staff in anatomical pathology in hospitals and specifically those involved in stem cell research. There are innumerable texts in light microscopy (LM) of basic histology that are now available for comparison to all and on line, particularly on Google, Wikipedia, PubMed and other search engines. Microanatomy is essentially a visual subject and the author firmly believes that a picture is worth a thousand words. The cell is the fundamental unit of structure in the human body. Cells and their products form the tissues and the various organs and organ systems of the human body. Understanding their structure is not only basic to microanatomy it is also of importance in the study of physiology and pathology and of course, gross anatomy. Now with dawn of stem cell research, it can be used as guide to understand adult and embryonic stem cell microstructure in conjunction with LM and immuno -fluorescent microscopy (FM). As an innovation to the original atlas we have added, exquisite colour images (SEM) by Prof. Pietro Motta, a world leader in electron microscopy, author and publisher of many atlases aided by his co-workers in La Sapienza, University of Roma, Italy, to appreciate the third dimension in microstructure. Some images of the testis are credited to Professors. David de Kretser & Jeff. Kerr, my colleagues at Monash University. Prof. de Kretser, of course, is one of my role models since he is an electron microscopist, clinician and expert on the testis and male infertility. He was founder Director of the Institute of Reproduction & Development, where I was honorary associate professor. He is also a born Sri Lankan and was Governor of Victoria. To help interpretation of the electron micrographs, the structure of each type of cell and/or tissue is illustrated diagramatically, and an attempt has been made to relate this to function. Where possible, such interpretative diagrams are printed adjacent to the electron micrographs of that particular type of cell/ tissue. Some of these diagrams were coloured by computer. In addition, brief descriptions of the anatomy of the cells/tissues and legends that describe the electron micrograph are included. Each section will briefly introduce the reader to the type of cell, tissue or organ that is being illustrated. Since there are many advanced atlases and textbooks on the fine structure of cells and tissues, the present publication is intended to be a simple reference for the student and researcher. One of the greatest difficulties readers have in the interpretation of cell structure using LM is that they do not see the outlines of cells and for the most part they do not see the internal structure of the cell very clearly. This is because the cell membrane and most of the internal structures are beyond the high resolution of the LM. Electron microscopy, on the other hand, magnifies cell organelles and enhances their resolution, making the interpretation of cell structure more precise and objective. However, there are limitations in the study of ultrastructure since only a very small section of the cell is viewed. Electron microscopy, as we all know, is laborious and very time consuming and has been used widely in biomedical research since 1935. We were the first to study embryonic stem cells by TEM, a logical progression of our extensive research on human gametes, fertilization and embryos in IVF & ART. The reader is advised to study images of cells and tissues in semi- thin epoxy sections (LM). This EBook (atlas) will be a valuable supplement to the numerous textbooks of histology, especially those with colour LMs of wax and epoxy sections. It covers the ultrastructure of the human cell, the basic tissues of the human body and some of the more important organs of the human body. It is specifically targeted to researchers involved in current stem cell research (both adult and embryonic). Finally, this publication is not intended to be a complete atlas of human cells and tissues since there are several excellent publications for the advanced study of electron microscopy, a few listed in the references.

Download or read book Ultrastructure of the Connective Tissue Matrix written by P. Motta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the techniques of electron microscopy have developed so widely and rapidly that they now cover the fields of research once the unique ll:panage of sister research techniques such as biochemistry, physiology, immunology, X-ray diffraction, etc. It is now possible to reach molecular and submolecular levels, making this technique indispensable in every type of research. Electron microscopy alone often provides enough information to solve given problems. In the field of the connective tissue matrix, knowledge of the molecular structure of collagen, pro teoglycans and elastin and their interaction has been to a large extent elucidated by electron microscopy. The field over which electron microscopy ranges in the investigation of the connective tissue matrix is so wide that the aim of this volume is to collect the main ultrastructural acquisitions disseminated in various journals and monographs in one book. The intent ofthis volume is to: (a) integrate different and new microscopic methods and review the results of such an integrative approach; (b) present a comprehensive ultrastructural account of selected aspects of the field; (c) point out gaps or controversial topics in our knowledge; (d) outline pertinent future research and expansion of the subject.
Download or read book Ultrastructure of Smooth Muscle written by P. Motta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent advances in electron microscopy have opened up new dimensions and perspectives in the field of morphology, and these are presently being integrated with biochemical and physiopathological phenomena occurring in cells, tissues, and organs. Methods such as freeze-fracture, freeze-etching, scanning, and high-voltage electron microscopy have contributed immensely to this progress, as well as to the study of smooth muscle tissue and contractile cells in general. The articles composing this book have been selected and edited with the purpose of updating and reviewing the most important aspects of smooth muscle cells as revealed by the integration of these submicroscopic techniques. The chapters of this volume have been prepared by some of the most authoritative experts in the discipline. Therefore each article not only offers the reader a concise review of the specific topic, but also seeks to highlight areas that require further investigation. Much of the volume is presented in an illustrative format so as to emphasize the remarkable results obtainable by the combination of the aforementioned methods, which allow a better appreciation of smooth muscle structure and ultrastructure. This volume, like others in the series, is intended not only for researchers in the field, but also for graduate students of histology, embryology, anatomy, physiology, and pathology in both medical and veterinary colleges. My hope is that this book will prove to be a valuable academic resource to the audience of the world in this fascinating and expanding field.

Download or read book Ultrastructure of Endocrine Cells and Tissues written by P. Motta and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innovative microscopic techniques, introduced during the last two decades, have contributed much to creating a new picture of the dynamic architecture of the cell, which can now be more exactly correlated with specific biochemical and physiopathological events. These developments have led to significant advances in our understanding of the physiomorphological and pathological aspects of the secretory mechanism, as well as the pharmacologic methods used to control, experimentally, the function of exocrine and endocrine glands. The integration of new ultrastructural methods such as freeze-fracture/etching, immunocytochemistry, scanning and high-voltage electron microscopy, cytoautoradiography, etc. , has proven to be of great value when applied to the study of endocrine cells and tissues. Because information on this topic has appeared in a variety of scientific and medical journals, this book: (1) reviews the results of an integrative approach presenting a comprehensive ultrastructural account of the main aspects of the field; (2) points out gaps or controversial topics in our knowledge; and (3) outlines pertinent directions for future research. The chapters, prepared by recognized authorities in the field, present traditional information on the topic in a concise manner and, with a valuable selection of original illustrations, show what the integration of new microscopic methods can contribute to the subject in terms of new concepts. This volume will be useful to cell biologists, anatomists, embryologists, histologists, pharmacologists, pathologists, and, of course, endocrinologists. It will also be of interest to students, practitioners of medicine, and to all others dealing with clinical research and diagnosis.
