• Sommario/riassunto: It is estimated that more than 4.5 million couples experience infertility each year, and more than 4 million babies have been born using IVF since 1978. However, assisted reproductive technologies continue to raise many medical, social, ethical, political and religious questions, often leading to controversial and sometimes inaccurate opinions about the outcomes of pregnancies resulting from these techniques. This is the first book dedicated to pregnancies arising from assisted reproductive technologies (ART). Chapters cover the most important management issues, from early pregnancy to outcome of children resulting from ART, including gynaecological, genetic and obstetric complications. Each chapter is written and edited by leading experts in the field of human reproduction. A timely, practical and evidence-based guide to the management of ART pregnancies, based on 30 years of clinical experience, this is essential reading for reproductive and maternal-fetal specialists as well as general obstetricians and gynaecologists.

• Sommario/riassunto: When Wittig first developed and described phosphorus ylides, nobody could have imagined how useful and versatile this class of compounds could be. This book provides a comprehensive and up-to-date compilation of the chemistry and applications of phosphorus ylides in organic synthesis. The ylides are discussed as reagents in the synthesis of a broad range of substances, amongst them olefins, acetylenes, cyclic and heterocyclic compounds, in such naturally occurring compounds as pheromones, steroids and carotenoids, and pharmaceutically and biologically active compounds such as antibiotics and p

• Sommario/riassunto: Rice is the staple food for more than half of the world's population, yet cold temperatures during the cropping period cause a significant loss of yield. To cope with the world's increasing population, it is necessary to develop high yielding rice varieties that are tolerant to abiotic stress conditions, such as drought, salinity, and cold. This book provides a clear understanding of cold stress in rice in the hopes that it will provide insight to the subject for further research so that rice plants may be grown efficiently in cold regions with high productivity.
