This book is an an up-to-date survey and summary of present knowledge and future expectations regarding the environmental causes of congenital malformations in human beings, beginning with the earliest discoveries of the 20th century up to the latest ideas and problems at its end, presents views and comments on the progress made over the century in understanding human prenatal maldevelopment.

Serious congenital malformations are a major contributor to the infant death rate worldwide. Their nonhereditary causes are multiple and complex, and include infectious and metabolic dangers, disease medication, nutritional inadequacy, medicinal products, environmental agents and pollutants, among them. The cause of many however is still unknown. The wide range of these causes makes the defects of interest to those of a wide range of medical and investigatory backgrounds, especialy clinicians, fundamental scientists, and environmentalists.

Surprisingly, the beginning of a modern approach This collection of articles and commentaries is an to the problems of birth defects is relatively recent integration of information from many disciplines, and dates from Gregg's classical report in 1941 that and presents a comprehensive survey of both recent mothers who contracted rubella during the first tri and previously reported work related to the major mester of pregnancy gave birth to infants with severe aspects of birth defects. In particular, an attempt multiple anomalies.

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.

Foucault and the Government of Disability is the first book-length investigation of the relevance and importance of the ideas of Michel Foucault to the field of disability studies-and vice versa. Over the last thirty years, politicized conceptions of disability have precipitated significant social change, including the landmark Americans with Disabilities Act in 1990, the redesign of urban landscapes, the appearance of closed-captioning on televisions, and the growing recognition that disabled people constitute a marginalized and disenfranchised constituency. The provocative essays in this volume respond to Foucault's call to question what is regarded as natural, inevitable, ethical, and liberating, while they challenge established understandings of Foucault's analyses and offer fresh approaches to his work. The book's roster of distinguished international contributors represents a broad range of disciplines and perspectives, making this a timely and necessary addition to the burgeoning field of disability studies.
