This book was released on 2013-03-09 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in basic biological research have proceeded rapidly in recent years. The fields of molecular genetics and immunology have experienced dramatic breakthroughs, capturing the imagination of both the scientific community and the general public. With less public notice, receptor biology has brought a cascade of new discoveries and insights. The entire science of pharmacology has been virtually rewritten in terms of receptor phenomenology. In particular, the discovery of specific receptors for steroid and protein hormones has been of seminal importance. With this new information, we have advanced our understanding of the mechanism and specifity of hormone action. We can now explain how hormones interact selectively with specific target cells and how hormones alter biochemical events within the target cells. These facts have already impacted on applied problems of clinical medicine, particularly in diagnosis and treatment of cancer and some metabolic diseases. Now, a new and important application of basic receptor biology and chemistry looms ahead. Within a few short years since the discovery of the progesterone receptor, chemists have synthesized molecules with a greater affinity for the receptor than progesterone itself and which, while occupying the receptor, fail to trigger the events which transform a target cell from the unstimulated to the stimulated state. This is the basis of the competitive inhibitory action of the anti-progestational agent, synthesized by the chemists at Roussel Uc1af, Paris, and designated RU 486.
Download or read book Clinical Applications of Mifepristone RU486 and Other Antiprogestins written by Institute of Medicine and published by National Academies Press. This book was released on 1993-02-01 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Contraceptive Research and Development written by Institute of Medicine and published by National Academies Press. This book was released on 1996-11-04 with total page 534 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "contraceptive revolution" of the 1960s and 1970s introduced totally new contraceptive options and launched an era of research and product development. Yet by the late 1980s, conditions had changed and improvements in contraceptive products, while very important in relation to improved oral contraceptives, IUDs, implants, and injectables, had become primarily incremental. Is it time for a second contraceptive revolution and how might it happen? Contraceptive Research and Development explores the frontiers of science where the contraceptives of the future are likely to be found and lays out criteria for deciding where to make the next R&D investments. The book comprehensively examines today's contraceptive needs, identifies "niches" in those needs that seem most readily translatable into market terms, and scrutinizes issues that shape the market: method side effects and contraceptive failure, the challenge of HIV/AIDS and other sexually transmitted diseases, and the implications of the "women's agenda." Contraceptive Research and Development analyzes the response of the pharmaceutical industry to current dynamics in regulation, liability, public opinion, and the economics of the health sector and offers an integrated set of recommendations for public- and private-sector action to meet a whole new generation of demand.

This book was released on 2013-06-29 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The annual meeting of the Perinatal Biochemical Group of the Spanish Biochemical Society held in Madrid on December 15-16, 1989, provided an excellent opportunity to bring together a group of distinguished investigators both from Spain and from abroad with a common interest in developmental endocrinology and biochemistry. The aim of the symposium was to present and discuss the most recent developments in the areas of endocrine and biochemical processes critical to normal growth and maturation of the newborn. To achieve a high degree of interaction among the participants, subject reviews as well as short communications were include in the program. The reviews provided in-depth information on selected important topics. The purpose of short communications was two fold: (i) to provide a forum to discuss on-going investigations on related areas; and (ii) to present opportunities for active participation by young investigators. This format proved very successful in generating fruitful discussions among the participants. Taken together the review chapters and the short communications have resulted in a coherent and unified subject presentation. Advances in biochemistry, molecular biology and cell biology have provided not only new and exciting experimental approaches but also have opened up new directions in the investigation of differentiation and developmental processes at cellular, molecular and biochemical levels during the early stages of growth and maturation. In recent years a wealth of information in these areas of development has emerged at a rapid rate.

Available in PDF, EPUB and Kindle. Book excerpt: By all indicators, the reproductive health of Americans has been deteriorating since 1980. Our nation is troubled by rates of teen pregnancies and newborn deaths that are worse than almost all others in the Western world. Science and Babies is a straightforward presentation of the major reproductive issues we face that suggests answers for the public. The book discusses how the clash of opinions on sex and family planning prevents us from making a national commitment to reproductive health; why people in the United States have fewer contraceptive choices than those in many other countries; what we need to do to improve social and medical services for teens and people living in poverty; how couples should "shop" for a fertility service and make consumer-wise decisions; and what we can expect in the futureâ€"featuring interesting accounts of potential scientific advances.
Download or read book Prostaglandins and the Uterus written by James O. Drife and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of prostaglandins into clinical practice has been one of the most important advances in obstetrics and gynaecology in recent years. During the last decade obstetricians have become familiar with these drugs for inducing labour and for terminating second-trimester pregnancy. Within the last year their use has been extended, in association with antiprogestin, to first-trimester termi nation. Although the effectiveness of prostaglandins in these pharma cological roles is clear, their full potential has still to be explored, and much remains to be learned about their physiology. Prostaglandins playa central role in the initiation of labour. Further clarification of this role could lead to improvements in preventing or treating preterm labour, which still remains the most important cause of perinatal mortality in this country. Prostaglandins are also inti mately involved in the mechanism of menstruation. More detailed understanding of this role should lead to more effective treatments for menorrhagia and dysmenorrhoea. These substances also playa part in the mechanism of implantation, and further research in this area may lead to more effective therapy for infertility.

Download or read book The Life Cycle of the Corpus Luteum written by Rina Meidan and published by Springer. This book was released on 2016-11-02 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the life cycle of a unique endocrine gland that is absolutely essential for the establishment and maintenance of pregnancy in all mammalian species. The corpus luteum is unique because it is formed and destroyed every (non-fertile) reproductive cycle. When fertilization occurs, the corpus luteum is rescued or maintained. The processes that control corpus luteum formation, demise (luteolysis), or maintenance are just beginning to be unraveled in recent years; they involve diverse cell types and mechanisms. Some of these processes resemble tumor development—angiogenesis, for instance—but interestingly enough, this resemblance is only up to a point. The corpus luteum uses mechanisms that allow its normal, physiological growth and disappearance. Pulling together key research on the corpus luteum, this volume is of interest to both reproductive endocrinologists and comparative physiologists, with clinical relevance spanning comparative animal studies to women's health.

Download or read book Targeted Intracellular Drug Delivery by Receptor Mediated Endocytosis written by Padma V. Devarajan and published by Springer Nature. This book was released on 2019-11-09 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book elaborates on drug delivery targeting via intracellular delivery, specifically through the Receptor Mediated Endocytosis (RME) approach, due to the involvement of cellular receptors in various grave diseases. Targeted delivery relies on two basic approaches, passive and active targeting. While passive targeting approaches have shown great promise, the improved selectivity achieved with active targeting approaches has resulted in significantly higher efficacy. Interestingly there are numerous strategies for active targeting, many of which are already highlighted in , Targeted Drug Delivery: Concepts and Applications. Nevertheless an exciting and practical strategy for active targeting, which could enable high intracellular delivery, is through exploitation of RME. Cells in the body express receptors to enable various physiological and biochemical processes. As a result, many of these receptors are overexpressed in pathological conditions, or newer receptors expressed due to defective cellular functioning. RME is based on exploitation of such receptors to achieve intracellular delivery. While targeted delivery can have manifold applications, in this book we focus on two major and challenging therapeutic areas; i) Cancer and ii) Infectious Diseases. Targeted Intracellular Drug Delivery by Receptor Medicated Endocytosis discusses the major receptors that are useful for targeted delivery for these afflictions. A major section of this book is dedicated to details regarding their occurrence and location, the recognition domain of the receptor, structure activity relationship of substrate /ligand for selective binding, ligands explored, antagonists for ligand binding and relevance of these aspects for therapy of cancer and infectious diseases. These facets are elucidated with the help of specific examples from academic research and also emphasize commercial products, wherever relevant. In vitro cellular models relied on for assessing receptor mediated cellular targeting and in vivo models depicting clinical efficacy are focused on in a separate section. Finally, we briefly discuss the regulatory and toxicity issues that may be associated specifically with the RME approach of intracellular drug delivery.
Download or read book Immunosuppression by Progesterone in Pregnancy written by Julia Szekeres-Bartho and published by CRC Press. This book was released on 1992-03-18 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immunosuppression by Progesterone in Pregnancy describes a newly discovered feto-protective mechanism resulting from the interaction of the immune and endocrine systems. As a response to antigenic stimulation by the fetus, lymphocytes of pregnant women develop non-classical progesterone receptors. Receptor binding of progesterone in the lymphocytes triggers the production of a mediator protein. Through an immunological pathway, this protein prevents abortion in murine models, and its serum concentration correlates with pregnancy outcome in humans. The regulation of these unusual receptors, as well as diagnostic and therapeutic implications of the mediator protein, are discussed. Immunologists, reproductive biologists, obstetricians, gynecologists, and other researchers studying this aspect of reproductive biology will find the book to be indispensable.
