Western knowledge of progress in biomedical research in Russia is severely limited by the scarcity of Russian journals available to us as well as the fact that few of us can read Russian. Therefore, it is of special significance that this recent contribution to the Russian scientific literature has been trans lated into English. This publication, Thyroid Hormones, brings to us a detailed analysis of recent work in Russia, and in particular in the Laboratory of Hormone Biochemistry, Institute of Biochemistry, Academy of Science of the Uzbek SSR and the Laboratory of Pathological Physiology, Institute of Experi mental Endocrinology and Hormone Chemistry, Academy Medical of Science of the USSR. The review illustrates the parallel pathways of inves tigation taken by investigators in Russia and in the West, indicating where the results have complemented each other or stimulated new questions and approaches. Consequently, the book provides an excellent review of the contributions made by Russian scientists in thyroid research and couples it with Western thought on these subjects to produce a complete review of the thyroid hormones. The large amount of data provided and the inclusion of multiple view points toward specific problems provides an excellent survey of the mecha nisms of biosynthesis and control of hormone formation, physiological effects of the hormones, and the molecular mechanisms involved in thyroid hormone action.

An authorised reissue of the long out of print classic textbook, Advanced Calculus by the late Dr Lynn Loomis and Dr Shlomo Sternberg both of Harvard University has been a revered but hard to find textbook for the advanced calculus course for decades. This book is based on an honors course in advanced calculus that the authors gave in the 1960's. The foundational material, presented in the unstarred sections of Chapters 1 through 11, was normally covered, but different applications of this basic material were stressed from year to year, and the book therefore contains more material than was covered in any one year. It can accordingly be used (with omissions) as a text for a year's course in advanced calculus, or as a text for a three-semester introduction to analysis. The prerequisites are a good grounding in the calculus of one variable from a mathematically rigorous point of view, together with some acquaintance with linear algebra. The reader should be familiar with limit and continuity type arguments and have a certain amount of mathematical sophistication. As possible introductory texts, we mention Differential and Integral Calculus by R Courant, Calculus by T Apostol, Calculus by M Spivak, and Pure Mathematics by G Hardy. The reader should also have some experience with partial derivatives. In overall plan the book divides roughly into a first half which develops the calculus (principally the differential calculus) in the setting of normed vector spaces, and a second half which deals with the calculus of differentiable manifolds.

Lipid-derived molecules are increasingly appreciated as key regulators of cell responses and signal transduction. Sphingolipid-derived bioactive molecules are emerging as critical regulators of some of the most exciting and, until recently, poorly-understood areas of biology such as growth suppression, programmed cell death and tumor invasion. Written by leading investigators in these areas of study, this book presents a thorough, current and accessible review of how sphingolipids function to regulate these important activities.
