Molecular Structure and Biological Activity of Steroids


Book Description

Molecular Structure and Biological Activity of Steroids focuses on the indentification of steroid structural features that control particular biological effects. Steroid geometry plays a critical role in steroid activity; therefore, the results of X-ray crystallographic, NMR spectroscopic, and theoretical studies on structure-activity relationships form an integral part of the book. Well-established observations and proposed models are presented, summarizing knowledge of molecular features (e.g., steroid backbone structures, side-chain constitutions, substitution sites, configurations, hydrogen-bonding patterns) that can affect steroid action. The book also provides overviews about recent progress in various frontier fields of steroid research, including such areas as sex steroids, glucocorticoids, aromatase inhibitors, vitamin D metabolites, brassinosteroids, neuromuscular blocking agents, and cardiotonic steroids. Molecular Structure and Biological Activity of Steroids is a "must-have" resource for biochemists, pharmacologists, endocrinologists, biophysicists, and others actively involved in steroid research.




Reproductive Endocrinology and Biology


Book Description

We have now reached the mid-point of our editorial task of putting together the compendium, Principles of Medical Biology, which is supposed to be composed of twenty-five modules. The present single-volume module on reproductive endocrinology and biology is in more than one respect a continuation of Module 10 (in two volumes) dealing with molecular and cellular endocrinology. In addition, it intersects, as it should, with various parts of obstetrics and gynaecology, both of which are abetted by technology. One has only to recall that the practical benefits of ultrasound in perinatal medicine and in vitro fertilisation are the outcome of the technological revolution in biomedicine. Whether we are approaching a new era in reproductive biology following the invention of animal cloning is still hard to tell. For some people, it remains an article of faith that cloning of the human being is highly probable. For others, asexual reproduction is anathema. It should surely be obvious to us all that somatic cell nuclear transfer technology (SCNTT) is going to be at its strongest in dealing with husbandry. Whether this and several social forces will alter our modern outlook, there can be little doubt.As in diverse clinical and basic research, so in obstetrics, animals are used as a model. The data thus obtained is extrapolated, if valid, to the mother and foetus. The success of this approach is exemplified in studies carried out on sheep as a model. On the whole, it is also quite apparent that progress in the field of reproductive biology is to a large extent ascribable to the discovery in other disciplines of new hormones, as well as the introduction of new tools and recent improvements in laboratory methods including measurement of hormones.

Clinical Applications of Mifepristone (RU486) and Other Antiprogestins


Book Description

Mifepristone (RU486), the first clinically available antiprogestin, has generated great interest since its discovery in the early 1980s. Today, it is recognized that mifepristone, along with other antiprogestins, has a potentially significant therapeutic role in human health and disease, with likely applicability to a variety of pregnancy-related conditions (e.g., management of labor) and to contraception, endometriosis, and cancer, among others. But because mifepristone has been studied and used most widely as a means of nonsurgical abortion, political issues have thus far limited research on the drug and prevented its introduction into the U.S. market. This book provides an unbiased evaluation of current knowledge about both the fundamental nature of antiprogestins as well as their possible use in treating numerous diseases and conditions, and it contains recommendations for future research.




Drosophila Cells in Culture


Book Description

Currently Drosophila is a dominant experimental model in developmental biology and in gene regulation in eukaryotes. This volume summarizes some thirty years of experience in the handling of in vitro cultured Drosophila cells. Its main emphasis is on gene transfer methodology, cell responses to heat shock, hormonal regulation of genes, and on the expression and mobility of transposable elements. - Some thirty years of experience in handling in vitro cultured Drosophila cells - Cell cultures which provide material for a multiplicity of biochemical approaches - DNA-mediated gene transfer as an irreplaceable tool for analyzing basic mechanisms of regulation - Drosophila cell lines which qualify them for use in biotechnology




Signalling Mechanisms — from Transcription Factors to Oxidative Stress


Book Description

A NATO Advanced Study Institute on "Molecular Mechanisms of Transcellular Signaling: from the Membrane to the Gene" was held on the Island of Spetsai, Greece, from August 15- 27, 1994. The aim of this Institute was to bring together researchers in the field of signal transduction mechanisms, transcription factors and gene regulation with those actively involved in studies on the implications of oxygen radicals and antioxidant defence mechanisms for cell function. As diverse as these fields may be, the emergence of their interconnection during the course of the Institute was an eye-opener for students and lecturers alike. 2 Presentations and discussions focussed on the role of Ca +, G-proteins, protein kinase C and phospholipases in signaling mechanisms. These broad principles were extended to transcription factors and gene regulation with an emphasis on the steroid hormone receptor superfamily and NFKB. Basic principles of free radical formation and antioxidant action (vitamin E and C) were presented and discussed in connection with effects on signaling pathways. This book present the content of the major lectures and a selection of the most relevant posters. These proceedings offer a comprehensive account of the most important topics discussed at the Institute. The book is intended to make the proceedings accessible to a large audience.




Sexual Differentiation of the Brain (2000)


Book Description

Sexual difference in the brain has long been one of the more intriguing research areas in the field of neuroscience. This thorough and comprehensive text uncovers and explains recent neurobiological and molecular biological studies in the field of neuroscience as they relate to the mechanisms underlying sexual differentiation of the brain. Attempts have been made to clarify sex differences in the human brain using noninvasive techniques such as magnetic resonance imaging. Sexual Differentiation of the Brain thoroughly examines these techniques and findings, providing an up-to-date, comprehensive overview written by leading researchers in the field. Just a few of the topics addressed include genetic contributions to the sexual differentiation of behavior; in-vitro studies of the effects of estrogen on estrogen receptor-transfected neuroblastoma cells; and the evolution of brain mechanisms controlling sexual behavior. Other topics include sexual differentiation of neural circuitry in the hypothalamus; structural sex differences in the mammalian brain; and sexual differentiation of cognitive functions in humans. With its revealing and informative chapters, as well as provocative treatment of the subject matter, Sexual Differentiation of the Brain helps shed new light on one of the most fascinating areas of brain research.
