Book excerpt: The placenta is fascinating and complex. Basically foreign to the maternal body, it can be thought of as an organ transplanted onto the mother's host tissue. As such it embodies all the principles of tissue acceptance and rejection. Many of the risks of pregnancy and labor have now been eliminated and the placenta is likely to be at the root of many of the dangers to the unborn child that remain. A breakdown of the relationship between the placenta and the maternal tissue may turn out to be the cause of the majority of early lost pregnancies.
Book Synopsis Comparative Placentation by : Peter Wooding
Download or read book Comparative Placentation written by Peter Wooding and published by Springer Science & Business Media. This book was released on 2008-08-22 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Science produces fascinating puzzles: why is there such a range of placental structures when other mammalian organs are so structurally uniform ? Why and how did the different placental structures evolve ? Comparative placental studies can facilitate the identification of the common factors in placental growth, differentiation and function and their relevance to possible evolutionary pathways. Comparative Placentation is the only book presenting up-to-date data illustrating the great variety of structure but uniform function of vertebrate placentas from fish to man. This information is essential for selection of suitable models to investigate particular practical problems of impaired or anomalous growth in human and animal placentation. The unique collection of the best light and electron micrographs from the last thirtyfive years which precisely illustrate the structural range in each taxon, make the book the most authoritative publication in this field and a vital source of information for anyone interested on reproductive physiology, anatomy and medicine.

Book Synopsis Placentation in Mammals by : Rodney D. Geisert
Download or read book Placentation in Mammals written by Rodney D. Geisert and published by Springer Nature. This book was released on 2021-10-25 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume of the book series Advances in Anatomy, Embryology and Cell Biology brings together current reviews from leading experts to address the diversity of placentation by which species establish and maintain pregnancy. Development of viviparity and placentation in rodents, dogs, pigs, cattle, horses, marsupials, primates and elephants are discussed. The development of viviparity in mammals, including some invertebrate species, required the adaptation of the placenta to serve as a functional conduit for interplay between the semiallograftic fetus with the maternal uterus. Although the ‘placenta’ protects the fetus from maternal immune rejection and provides oxygen and nutrient flow to support it to term across all the species, structural differentiation of this fetal-maternal interface can vary from simple to very complex. E.C. Amoroso contributed greatly to our early understanding and knowledge of placentation across a great variety of species. His work on placentation provides numerous illustrations and histological sections which are used for teaching and stimulating research today. With this book, we want to pay tribute to his lifetime contributions to the field by reviewing our current understanding of the development of viviparity and placentation in different species. The book is written for researchers, physicians and medical students working in the field of reproductive science or with an interest in placentation and viviparity.
Book Synopsis The Evolution of the Human Placenta by : Michael L. Power
Download or read book The Evolution of the Human Placenta written by Michael L. Power and published by JHU Press. This book was released on 2012-10-01 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the active interface of the most biologically intimate connection between two living organisms, a mother and her fetus, the placenta is crucial to human evolution and survival. Michael L. Power and Jay Schulkin explore the more than 100 million years of evolution that led to the human placenta and, in so doing, they help unravel the mysteries of human life's first moments. Starting with some of the earliest events that have influenced the path of placental evolution in mammals and progressing to the specifics of the human placenta, this book examines modern gestation within an evolutionary framework. Human beings are a successful species and our numbers have increased dramatically since our earliest days on Earth. However, human fetal development is fraught with poor outcomes for both the mother and fetus that appear to be, if not unique, far more common in humans than in other mammals. High rates of early pregnancy loss, nausea and vomiting during pregnancy, preeclampsia and related maternal hypertension, and preterm birth are rare or absent in other mammals yet not unusual in humans. Power and Schulkin explain why this apparent contradiction exists and address such topics as how the placenta regulates and coordinates the metabolism, growth, and development of both mother and fetus, the placenta’s role in protecting a fetus from the mother’s immune system, and placental diseases. In the process, they reveal the vital importance of this organ—which is composed mostly of fetal cells—for us as individuals and as a species. -- Errol R.

Book Synopsis Comparative, Maternal, and Epidemiologic Aspects by : James Wilson
Download or read book Comparative, Maternal, and Epidemiologic Aspects written by James Wilson and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modification of embryonic development by genetic differences in the mother is a well-regcognized phemomenon, but little is known about the genet ics of these maternal traits or the mechanisms by which they act. To illustrate the genetic approach to the problem, examples are given of how differences in embryonic response to a teratogen can be partitioned into those resulting from differences in embryonic genotype (including the possible role of X-linked genes in producing reciprocal cross differences), maternal genotype, and cytoplasmically transmitted factors. The advantages and limitations of analysis by appropriate crosses, in utero treatments, embryo transfers, and in vitro experiments are illustrated. The numerous inbred strains of the mouse, with well-documented physiology, the recently developed recombinant inbred strains, and the existence of easily identified biochemical marker genes offer at tractive opportunities, so far largely unexploited, for causal analysis of mater nal effects on teratological responses. VII. ADDENDUM Since this chapter was written, several relevant papers have appeared. The strain difference between AI] and C57BU6] mice in frequency of cleft-palate response to cortisone was fitted to a model of normally distributed log tolerance (Biddle and Fraser, 1976). Genetic differences, both in maternal uterine environment and embryonic response, can be represented in terms of their effect on the median effective dose required for the cleft-palate re sponse. The maternal effect of AI] dams relative to C57BU6] dams caused a two-fold reduction in embryonic tolerance to cortisone-induced cleft palate.

Book Synopsis Reproductive Biology of the Great Apes by : Charles Graham
Download or read book Reproductive Biology of the Great Apes written by Charles Graham and published by Elsevier. This book was released on 2012-12-02 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reproductive Biology of the Great Apes: Comparative and Biomedical Perspectives discusses the great ape reproduction. The book opens with the menstrual cycle of apes as a good foundation for the subject areas that follow. Accordingly, Chapter 2 focuses on the endocrine changes during the stage of pregnancy among apes, specifically the hormonal changes in chimpanzee. Chapter 3 deals mainly on the condition postpartum amenorrhea. In Chapter 4, the reproductive and endocrine development – from fetal development, infancy, juvenile, to puberty – is discussed. Chapters 5 and 6 thoroughly discuss the female and male ape's genital tract and their secretions. The sole topic of Chapter 7 deals mainly with the comparative aspects of ape steroid hormone metabolism. Meanwhile, Chapter 8 tackles laboratory research on apes' sexual behavior. The succeeding chapters talk about the chimpanzee, gorilla, and orangutan reproduction in the wild. Chapters 12 and 13 basically look upon the behaviors of the great apes, specifically intermale competition and sexual selection. The next chapters (14 and 15) look at the necessity of breeding and managing apes in captivity to ensure their continued survival. Lastly, Chapter 16 highlights the significance and great value of apes as models and comparative study in human reproduction. This book will be of great use to human physiologists, comparative anatomists and zoologists, primatologists, ape breeders, and biomedical scientists.
Book Synopsis Teratological Testing by : T.V.N. Persaud
Download or read book Teratological Testing written by T.V.N. Persaud and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of birth defects has assumed an importance even greater now than in the past because mortality rates attributed to congenital anomalies have declined far less than those for other causes of death, such as infectious and nutritional diseases. It is estimated that as many as 50% of all pregnancies terminate as miscarriages. In the majority of cases this is the result of faulty development. Major congenital malformations are found in at least 2% of all liveborn infants, and 22% of all stillbirths and infant deaths are associated with severe congenital anomalies. Teratological studies of an experimental nature are neither ethical nor justifiable in humans. Numerous investigations have been carried out in laboratory animals and other experimental models in order to improve our understanding of abnormal intra-uterine development. In less than two decades the field of experimental teratology has advanced phenomenally. As a result of the wide range of information that is now accumulating, it has become possible to obtain an insight into the causes, mec.;hanisms and prevention of birth defects. However, considerable work will be needed before these problems can be resolved. The· contributions in this volume deal primarily with the areas of terato logical evaluation and the use of selected animal models for the study of con genital anomalies. It is not only a documentation of the latest experimental work, but it also indicates new and important areas for future research.

Book Synopsis The Placenta and Human Developmental Programming by : Graham J. Burton
Download or read book The Placenta and Human Developmental Programming written by Graham J. Burton and published by Cambridge University Press. This book was released on 2010-12-16 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developmental programming is a rapidly advancing discipline of great importance to basic scientists and health professionals alike. This text integrates, for the first time, contributions from world experts to explore the role of the placenta in developmental programming. The book considers the materno-fetal supply line, and how perturbations of placental development impact on its functional capacity. Chapters examine ways in which environmental, immunological and vascular insults regulate expression of conventional and imprinted genes, along with their impact on placental shape and size, transport, metabolism and endocrine function. Research in animal models is integrated with human clinical and epidemiological data, and questions for future research are identified. Transcripts of discussions between the authors allow readers to engage with controversial issues. Essential reading for researchers in placental biology and developmental programming, as well as specialists and trainees in the wider field of reproductive medicine.
