Book Description
The optimal function of the placenta and thus fetal well being largely depends upon the integrity of both the fetal and maternal circulations of the placenta. Intense basic research concerned with placental vascularization and blood flow has been performed for the past 30 years, beginning with the classical morphological descriptions of the placental vessels by Boe (1953) and Arts (1961), as well as with the radioangiographic studies of maternal placental circulation in the human by Borell (1958) and in the rhesus monkey by Ramsey (1962). The scientific framework presented by these investigators has been filled and completed by numerous investigators, leading to more morphological details, functional considerations, and pathological understanding. For an extended period of time, this research has been of primarily academic interest by increasing our insights into one important system of the placenta, yet having nearly no practical importance. Recently, this situation has changed dramatically: in vitro studies of the isolated, dually perfused human placenta and in vivo studies of placental circulation for diagnostic purposes have raised an enormous interest in basic research data. New methods like Doppler Ultrasound and NMR became available. These technics have enabled the obstetrician to study fetal and placental hemodynamics in vivo. Meanwhile, such methods are becoming incorporated into the daily obstetrical routine, to some degree without an adequate background knowledge of placental vascularization and blood flow, since such experience is currently available to only a small group of experts.

Book Description
This is a completely new, second edition of the classic reference which has been out of print since 1984. It is the most comprehensive work available on placental pathology, which has recently gained importance in clinical medicine, and includes discussion of legal aspects dealing with the relation between placenta and perinatal damage.

Book Description
Pathology of the Human Placenta remains the authoritative text in the field and is respected and used by pathologists and obstetrician-gynecologists alike. This fifth edition reflects new advances in the field and includes 800 illustrations, 173 of them in color. The detailed index has been improved and the tables updated. Defined terms are highlighted in bold for easy identification, and further findings are discussed in small type throughout each chapter. Advances in genetics and molecular biology continue to make the study of the placenta one of vast diagnostic and legal importance.

Book Description
Regulation of Ventilation and Gas Exchange is a comprehensive account of the regulation of ventilation and gas exchange. Topics covered include central nervous system regulation of ventilation; ventilatory response to muscular exercise; respiratory control in air-breathing ectotherms; and breathing during sleep. Hydrogen ion homeostasis of the cerebral extracellular fluid is also discussed, along with specific mechanisms for O2 and CO transport in the lung and placenta. Comprised of nine chapters, this book begins with an overview of the neural elements that modify and/or are intrinsic to the respiratory rhythm. The next two chapters deal with the contribution of metabolic factors in the control of ventilation, paying particular attention to the importance of metabolic factors during muscular exercise and the specific role of ammonia in the regulation of respiration. A view of ventilatory control from a comparative standpoint, stressing both adaptive and mechanistic phenomena, is then presented. Subsequent chapters explore the regulation of breathing during sleep; regulation of cerebral extracellular fluid acid-base composition and its role in the control of ventilation and cerebral blood flow; carrier-mediated transport of respiratory gases; and measurement of ventilation-perfusion ratios is presented. The last chapter considers lung surfactant mechanics and addresses issues such as in vitro vs in situ measurements of surface tension and the effects of surface tension on pulmonary vascular resistance and interstitial pressure. This monograph is designed not only for respiratory physiologists but also for students and researchers in other areas with an inclination toward respiratory physiology.

Book Description
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 Description
The Permanent Commission and International Association on Occupational Health (PCIAOH) established in 1969 a Subcommittee on the Toxicology of Metals under the chairmanship of Lars Friberg. This committee, which later was named the Scientific Committee on the Toxicology of Metals, has organized a number of previous meetings that have led to publications in three major areas of metal toxicology: a preliminary meeting in Slanchev Bryag, Bulgaria in- 1971, followed by a meeting in 1972 in Buenos Aires, Argentina which produced two reports (Dukes and Friberg, 1971; Task Group on Metal Accumulation, 1973), that discussed the metabolism of metals with special reference to absorption, excretion and biological half-times. The effects and dose-response relationships of toxic metals, including a discussion of general principles, was the second major topic addressed by the Scientific Committee at a meeting in Tokyo in 1974 (Nordberg, 1976). The philosophy of this conference, as well as the previous one in Buenos Aires, was based on the concept of a "threshold dose" for the occurrence of adverse effects. In a conference held in Atlanta, USA in 1980, the scope of discussion on metal effects was broadened to include the role of metals in carcinogenesis. Thus, for the first time, the Scientific Committee took under consideration the possibility of non-threshold relationships (Belman and Nordberg, 1981). In addition, the Scientific Committee on the Toxicology of Metals organized a workshop on metal interactions in Stockholm 1977 (Nordberg et al.

Book Description
Fetal Physiology and Medicine: The Basis of Perinatology, Second, Revised Edition documents many of the major advances in fetal medicine, including developmental physiology, pathology, and therapy. This book covers the most important areas of maternofetal medicine and presents different views of the critical problems of development. The various components of fetal metabolism are highlighted to demonstrate how animal experimentation has given a clear view of the interrelationship of the mother, placenta, and fetus. This text is comprised of 24 chapters; the first of which describes the use of ultrasound in antenatal diagnosis of congenital structural anomalies. This topic is followed by a discussion on sexual differentiation, acquired immunity, and endocrine changes, as well as the physiology of breathing, the control of the fetal cardiovascular system, lung maturation, fetal infections, and the effects of hypoxia on the fetal brain. This book also provides comprehensive reviews of fetal regulatory mechanisms, such as the reninangiotensin system, water metabolism, and fetal and placental hormone production. Other chapters focus on clinical applications, such as antenatal fetal heart rate monitoring, the technical aspects of fetal and uterine pressure measurements, fetal acid-base balance, and the prevention of preterm delivery. A section that explores the transition from intrauterine to extrauterine life concludes this book. This source is of great potential value to all students and practitioners of reproductive medicine.
