Available in PDF, EPUB and Kindle. Book excerpt: Advances in the development and application of electron microscopic techniques have occurred recently such that the electron microscope has evolved to become an essential tool in both basic and clinical research. Use of this instrument has contributed significantly to the formation of new perspectives and concepts concerning cell fine structure. These structural perspectives are now being integrated with specific functional, biochemical and pathophysiological events and processes of cells and tissues. Most recently, utilization of innovative electron microscopic techniques such as freeze-fracture, freeze etching, and scanning and high-voltage electron microscopy offers both the basic and clinical scientist potentially fundamental insights into many morphodynamic processes related to the activities of cells and tissues. Such an approach has been especially rewarding when applied to the dynamic events of gametogenesis and early embryonic development. The chapters comprising this book have been selected and edited with the aim of providing an up-to-date and comprehensive account of the most important aspects of vertebrate gamets and embryos as revealed by the integration of several different submicroscopic methods. The organization of the chapters is designed to indicate present gaps in our knowledge of the developmental and reproductive biology of gametes and the developing embryo and possible Iines of research which may lead to a lessening of these gaps.

This book was released on 2012-12-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last few years, the adoption and worldwide proliferation of clinical procedures for medically assisted conception have been associated with the examination and analysis of spermatozoa, oocytes and early embryos under a variety of in vivo and in vitro conditions. These analyses have enabled correlations to be made between the behavior of gametes, the pattern of early embryonic development and the initiation of a normal pregnancy. Collectively, the findings have not only enormously increased our understanding of the process of early human development, but also have provided new insights into the origin and causes of reproductive failure in man. The research presented in this volume describes recent results derived from the study of normal and abnormal patterns of human spermatogenesis, oogenesis and early embryogenesis. The chapters discuss aberrations in morphodynamic and morphophysiological processes that have clinical relevance in human infertility and conception. Two of the chapters describe, respectively, the basic research that allows the cryopreservation of human oocytes and embryos, and the development of in vitro systems that permit the study of cell differentiation and interaction during the peri-implantation period. When relevant, each chapter extrapolates findings from in vitro experimentation to the comparable situation that is observed in vivo.

Available in PDF, EPUB and Kindle. Book excerpt: Life is always intimately bound up with structure and with the continuous transformation which structures undergo. Modern science and technology have now made it possible to display these structures before our eyes, right up to the frontiers of molecular dimensions. When several years ago Dr. HANS LUDWIG, while working at the First Department of Obstetrics and Gynecology of the University at Munich, demonstrated to us some micrographs showing the human oviduct's surface pattern, my immediate reaction was: This is the environment that encom passes the very onset of an individual human life. In fact, scanning electron microscopy, superimposed upon classical micro morphology, has enabled us to get insight into the landscape of living structures, their intricate organization and their delicate beauty as well. At the same time this technique opens up an entirely new perspective in our three-dimensional view and comprehension of biological events. This becomes especially evident in the realm of reproductive processes within the human female reproductive tract. In this volume the authors give - for the first time systematically - a description of the surface patterns of the inside of the human vagina, ecto and endocervix, and the human uterus and oviduct; they depict ovulatory alterations of the ovarian surface and surface changes under various endo crine conditions, as well as in relation to the menstrual cycle, pregnancy, fetal growth, and the menopausal cessation of ovarian functional activity. of the placental intervillum, the In addition they describe surface structures basal plate and the amnion.

Available in PDF, EPUB and Kindle. Book excerpt: The Reproductive Biology of Bats presents the first comprehensive, in-depth review of the current knowledge and supporting literature concerning the behavior, anatomy, physiology and reproductive strategies of bats. These mammals, which occur world-wide and comprise a vast assemblage of species, have evolved unique and successful reproductive strategies through varied anatomical and physiological specialization. These are accompanied by individual and/or group behavioral interactions, usually in response to environmental mechanisms essential to their reproductive success. - Is the first book devoted to the reproductive biology of bats - Contains in-depth reviews of the literature concerned with bat reproduction - Contributors are widely recognized specialists - Provides a powerful database for future research

Download or read book The Insect Ovary written by Jürgen Büning and published by Springer Science & Business Media. This book was released on 1994-07-31 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will give an overview of insect ovaries, showing the diversities and the common traits in egg growth processes. The idea to write this book developed while looking at the flood of information which appeared in the early 1980s on early pattern formation in Drosophila embryos. At this time a significant breakthrough was made in studies of this little fly, combining molecular biological methods with classical and molecular genetics. The answers to questions about early pattern formation raised new questions about the architecture of ovaries and the growth of eggs within these ovaries. However, by concentrating only on Drosophila it is not possible to form an adequate picture of what is going on in insect ovaries, since the enormous diversity found among insects is not considered sufficiently. Almost forgotten, but the first to study the architecture of ovaries, was Alexander Brandt writing in 1878 in aber das Ei und seine Bildungsstaette (On the egg and its organ of development). More than 100 years later, a series of ten books or more would be required to survey all the serious informa tion we have today on insect oogenesis. Thus, this book is a personal selection and personal view on the theme, and the authors must be excused by all those scientists whose papers could not be included. The book briefly describes the ectodemes, i. e.

Available in PDF, EPUB and Kindle. Book excerpt: This ground-breaking atlas of oocyte ultrastructure forms a practical guide to assisted reproduction. Extensively illustrated with transmission electron microscopic (TEM) images, it contains chapters on oocyte maturation, fertilization, fertilization failure, pitfalls and technical problems of intracytoplasmic sperm injection, and failed fertilization in vitro to explain the principles and evaluation of TEM images. A large chapter of TEM images of the ultrastructure of human oocytes illustrates fertilization failures after ICSI and IVF and the ultrastructure of germinal vesicle oocytes and metaphase I oocytes. It also contains detailed information about abnormal metaphase II oocytes with sections on autolysis, multi-vacuolated mature oocyte, refractile body, and fragmented oocyte. The concluding chapter describes materials and methods for single-cell transmission electron microscopy of the human oocyte.
