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, mechanisms and prevention of birth defects. However, considerable work will be needed before these problems can be resolved. This book brings together some of the more recent and important research findings related to the mechanisms and pathogenesis of abnormal develop ment. It is not only a documentation of the latest experimental work, but it also points out future directions that seem productive and challenging.

Download or read book Teratogens written by Vera M. Kolb and published by Elsevier. This book was released on 2013-10-22 with total page 595 pages. Available in PDF, EPUB and Kindle. Book excerpt: Teratogens Chemicals Which Cause Birth Defects, 2nd Revised Edition is a collection of papers that discusses the practical aspect of teratogens, particularly regarding information on the teratogenic potential of chemicals. This book describes the principles and mechanism of teratogenesis, including the initiating mechanisms during the subcellular or molecular level and the role of bio-activation in teratogenesis. Investigations have been done on the relationship between spontaneous abortion in women exposed to organic solvents, antineoplastic agents, and chemicals in plastics. Other studies also show that teratogenicity depends in part on enzymatic bio-activation to an embryotoxic reactive intermediate. This text also explains the legal and ethical aspects of fetal protection policies with emphasis on fetal protection. Protection to expecting women extends to pregnant students exposed to teratogenic chemicals in chemistry laboratories. The book explains how and where to get information about the teratogenic potential of chemicals and how to properly handle these chemicals in the laboratory. The book also provides a list from RTECs of toxic chemicals which can cause reproductive effects. This book can prove useful for chemists, pharmacologists, obstetricians, gynecologists, and practitioners of general medicine.

Download or read book The Oxford Handbook of Externalizing Spectrum Disorders written by Theodore P. Beauchaine and published by Oxford University Press. This book was released on 2015-10-01 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in the conceptualization of externalizing spectrum disorders, including attention-deficit/hyperactivity disorder, conduct disorder, antisocial personality disorder, and substance use disorders, suggest common genetic and neural substrates. Despite this, neither shared vulnerabilities nor their implications for developmental models of externalizing conduct are captured by prevailing nosologic and diagnostic systems, such as the DSM-5. The Oxford Handbook of Externalizing Spectrum Disorders is the first book of its kind to capture the developmental psychopathology of externalizing spectrum disorders by examining causal factors across levels of analysis and developmental epochs, while departing from the categorical perspective. World renowned experts on externalizing psychopathology demonstrate how shared genetic and neural vulnerabilities predispose to trait impulsivity, a highly heritable personality construct that is often shaped by adverse environments into increasingly intractable forms of externalizing conduct across development. Consistent with contemporary models of almost all forms of psychopathology, the Handbook emphasizes the importance of neurobiological vulnerability and environmental risk interactions in the expression of externalizing behavior across the lifespan. The volume concludes with an integrative, ontogenic process model of externalizing psychopathology in which diverse equifinal and multifinal pathways to disorder are specified.

Download or read book Issues and Reviews in Teratology written by Harold Kalter and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Teratology is at once among the oldest and youngest of human preoccupations. Coincident with man's first observations of the stars were his recordings of human and animal deformities. But, such aberrancies must have occurred even earlier, for although it is one of those things-like evolution-that cannot be proven, it is nevertheless indisputable that dysmorphogenesis must have occurred from the time complex forms of life first arose on our planet; and that from the beginnings of human awareness our species was conscious of such happenings. From the earliest recordings of this fascination with the form and meaning of abnormality a tortuous but continuous line extends to modern struggles to understand and control these manifestations. And now, after long occupying an honorable but peripheral place in the halls of philosophical and scientific pursuits, teratology has quite suddenly come to take a prominent position at the hub of a complex crossroads of human concerns. This shift in its fortune has taken several forms. Fetal maldevelopment has become the concern of environmentalists, activists of various persuasions, indus trial organizations, government agencies, ethicists, parents-i. e. , individuals and groups whose actions are impelled by apprehension. Such motives are of course not without basis; the trauma of thalidomide left a scar yet raw. For still others clinicians, academics, experimentalists-the upsurge in the interest in fetal mal development is at a different level, and their pursuits are broad, taking external agents as but one of the causes of defective development.

Download or read book Scientific Frontiers in Developmental Toxicology and Risk Assessment written by National Research Council and published by National Academies Press. This book was released on 2000-12-21 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.
