Conformal nets provide a mathematical model for conformal field theory. The authors define a notion of defect between conformal nets, formalizing the idea of an interaction between two conformal field theories. They introduce an operation of fusion of defects, and prove that the fusion of two defects is again a defect, provided the fusion occurs over a conformal net of finite index. There is a notion of sector (or bimodule) between two defects, and operations of horizontal and vertical fusion of such sectors. The authors' most difficult technical result is that the horizontal fusion of the vacuum sectors of two defects is isomorphic to the vacuum sector of the fused defect. Equipped with this isomorphism, they construct the basic interchange isomorphism between the horizontal fusion of two vertical fusions and the vertical fusion of two horizontal fusions of sectors.

This book focuses on the use of animal models to study various human defects. It summarizes our current understanding of a variety of common human birth defects and the essential role of animal models in shedding light on the underlying mechanisms of these disorders. Birth defects are the leading cause of infant deaths, and cost billions of dollars in care for those affected. Unfortunately, the lack of a clear understanding of the mechanisms leading to many of these developmental disorders has hindered effective prevention and early intervention strategies. Studies using animal models have provided essential insights into several human birth defects. This book serves as a valuable reference resource for researchers and graduate students who are interested in learning the basic principles as well as the latest advances in the study of the mechanisms of human birth defects.

The first edition of Embryos, Genes and BirthDefects, edited by the late Peter Thorogood, was a radicalnew book aimed at bridging the gap between the medical disciplinesof embryology and dysmorphology, and recent advances in cellular,molecular and developmental biology. This new edition remainsunique in its breadth and brings up to date our understanding ofbirth defects and of the strategies utilized to gain suchknowledge. It features new chapters on human cytogenetics,mutagenesis and the eyes and ears. The book presents key topics in developmental biology andexplains how they provide the foundations for understandingclinical birth defects. The first six chapters introduce conceptsand strategies adopted to elucidate developmental anomalies leadingto birth defects. The book then focuses on specific organs andreviews the cellular and molecular mechanisms affecting theirdevelopment and how disruption of these mechanisms by genetic orenvironmental factors may underlie certain birth defects. Thechapters are concise and provide up-to-date coverage of topics in aformat that is easily accessible and yet at the forefront ofresearch. Written primarily for paediatricians, obstetricians, clinicalgeneticists and allied workers, this book guides the reader throughthe contribution of modern molecular biology to our understandingof human development. Developmental and cellular biologists willlearn how errors in the cellular and genetic mechanism can lead toclassical disorders, diseases and syndromes.
