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.

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 The Health Effects of Cannabis and Cannabinoids written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-03-31 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant changes have taken place in the policy landscape surrounding cannabis legalization, production, and use. During the past 20 years, 25 states and the District of Columbia have legalized cannabis and/or cannabidiol (a component of cannabis) for medical conditions or retail sales at the state level and 4 states have legalized both the medical and recreational use of cannabis. These landmark changes in policy have impacted cannabis use patterns and perceived levels of risk. However, despite this changing landscape, evidence regarding the short- and long-term health effects of cannabis use remains elusive. While a myriad of studies have examined cannabis use in all its various forms, often these research conclusions are not appropriately synthesized, translated for, or communicated to policy makers, health care providers, state health officials, or other stakeholders who have been charged with influencing and enacting policies, procedures, and laws related to cannabis use. Unlike other controlled substances such as alcohol or tobacco, no accepted standards for safe use or appropriate dose are available to help guide individuals as they make choices regarding the issues of if, when, where, and how to use cannabis safely and, in regard to therapeutic uses, effectively. Shifting public sentiment, conflicting and impeded scientific research, and legislative battles have fueled the debate about what, if any, harms or benefits can be attributed to the use of cannabis or its derivatives, and this lack of aggregated knowledge has broad public health implications. The Health Effects of Cannabis and Cannabinoids provides a comprehensive review of scientific evidence related to the health effects and potential therapeutic benefits of cannabis. This report provides a research agendaâ€"outlining gaps in current knowledge and opportunities for providing additional insight into these issuesâ€"that summarizes and prioritizes pressing research needs.
