Download or read book Teratogenic Mechanisms written by T.V.N. Persaud and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 240 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, 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 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.

Book excerpt: This comprehensive atlas is unique in combining information on the embryological development of the human with detailed presentation of the congenital malformations encountered in clinical practice. As a consequence it will not only assist practitioners and trainees in recognizing and evaluating malformations, but also enable them to understand how a malformation has developed and to explain the mystery of congenital malformations to relatives and patients. The book is organized according to anatomic region, with additional chapters on hernias, tumors, lymphogenesis and lymphatic malformations. According to WHO statistics, each year congenital anomalies result in approximately 3.2 million birth defect-related disabilities worldwide. All too often, however, training in embryology is now a neglected area, and medical graduates frequently lack confidence in their knowledge of the field. Clinical Embryology: An Atlas of Congenital Malformations will help to rectify this deficit and to ensure that malformations are comprehended and managed appropriately. It will be of value for postgraduate trainees in pediatric surgery, pediatrics, and neonatology, undergraduate medical students, and general practitioners/family physicians.

Download or read book Cannabis and the Developing Brain written by Miriam Melis and published by Academic Press. This book was released on 2022-08-18 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marijuana is the most commonly used psychotropic drug in the United States, after alcohol. With the legalization and decriminalization of cannabis, momentum continues to build and propelled by the reduction of stigma associated to its consumption, there is growing concern regarding the long-term impact on brain function and behavior. Cannabis and the Developing Brain aims to provide comprehensive research on the effects of cannabis during neurodevelopment stages (i.e., perinatal and adolescent ages). This book introduces readers to vivo neural circuits, molecular and cellular mechanisms affected by cannabis exposure during three different temporal windows of brain vulnerability. Second, it offers a unique insight to shared neurobiological features of cannabinoid exposure during different developmental periods. Lastly, Cannabis and the Developing Brain determines the adverse impact of developmental cannabinoid exposure on specific cognition, emotion and behaviors. - Reviews exposure effects on different areas and circuits of the brain - Identifies effects of exposure at prenatal, perinatal, infant, and adolescent ages - Includes cannabis interaction with known genetic and environmental risk factors - Contains neurodevelopment and neuropsychiatric disorders associated with cannabis exposure
Download or read book Antipsychotic Drugs and Their Side Effects written by Thomas R.E. Barnes and published by Academic Press. This book was released on 2013-10-22 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: In line with other volumes in the Neuroscience Perspectives Series, this volume covers the background, pharmacology, molecular biology, and biochemistry of antipsychotic drugs, together with an overview assessment of the therapeutic considerations. Over the past 40 years, the effectiveness of conventional neuroleptic agents for psychotic illness has been offset by a wide range of adverse side-effects, including motor side-effects like parkinsonism. Studies show that lowering doses may still produce the antipsychotic effect while lessening the risk of side-effects. As all available antispychotic drugs are able to block dopamine, specifically D2 receptors, doses below the threshold level for producing acute motor disorder can still be therapeutically effective. With the identification and characterization of multiple dopamine receptors, the possibility of more selective drugs with better side-effect potential has arisen. Other novel antipsychotic agents include D1 receptor blockers, partial dopamine agonists and non-dopamine drugs such as 5-HT receptor blockers, sigma receptor antagonists and NMDA receptor agonists. This volume reviews both the basic science of the conventional and atypical neuroleptics and their present and potential therapeutic use.
Download or read book The Health Consequences of Involuntary Exposure to Tobacco Smoke written by and published by . This book was released on 2006 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Surgeon General's report returns to the topic of the health effects of involuntary exposure to tobacco smoke. The last comprehensive review of this evidence by the Department of Health and Human Services (DHHS) was in the 1986 Surgeon General's report, The Health Consequences of Involuntary Smoking, published 20 years ago this year. This new report updates the evidence of the harmful effects of involuntary exposure to tobacco smoke. This large body of research findings is captured in an accompanying dynamic database that profiles key epidemiologic findings, and allows the evidence on health effects of exposure to tobacco smoke to be synthesized and updated (following the format of the 2004 report, The Health Consequences of Smoking). The database enables users to explore the data and studies supporting the conclusions in the report. The database is available on the Web site of the Centers for Disease Control and Prevention (CDC) at http://www.cdc.gov/tobacco.
