This book was released on 2012-12-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: My introduction to androgens was neither auspicious nor impressive. I was sitting my viva voce examination for a degree in physiology and had haltingly intimated to my examiner (name decorously withheld) that I intended to pursue a career in re search. "On what topic?" was the reply. I had been deeply impressed by the work of C. Huggins and C. V. Hodges (Cancer Res. 1, 293, 1941) on the dramatic arrest of canine prostatic hyperplasia by the administration of stilboestrol. With some en thusiasm, I responded, "On steroid hormones, because I am struck by the profound effects that may be achieved by relatively small numbers of molecules. " The examiner sank into deep contemplation before replying, "Young man, have you considered go ing into teaching?" Suitably chastened, I finally began my research career investigating the effects of steroids on the nucleic acid metabolism of experimental tumours and on the process cells. Reaching an impasse in this work, I mentioned one of senescence in animal day to Dr. G. F. Marrian that, somewhat surprisingly, we had no understanding of the fundamental mechanism of action of steroid hormones, especially the androgens. me to tackle this problem, particularly since exciting new insights He encouraged were then being made into the interaction of radioactively labelled oestradiol-l?,8 with such tissues as rat uterus.

Download or read book Understanding Differences and Disorders of Sex Development DSD written by O. Hiort and published by Karger Medical and Scientific Publishers. This book was released on 2014-09-15 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ten years ago a group of experts assembled in Chicago to develop a consensus on the management of conditions previously described as intersex. The consequences of this consensus have been far reaching, including a change in nomenclature, the development of greater collaboration across geographical boundaries, and a move towards greater involvement of patients and parents. Moreover, an international registry was established, as well as research and clinical networks. This book brings together a thorough overview on all these topics. Furthermore, the major technological advances in diagnostic genetic and biochemical capabilities over the past 10 years are outlined in detail. Offering a comprehensive update on various aspects of disorders of sex development (DSD), this book will be essential reading to all clinicians who are involved in delivering health care to patients with a DSD, as well as scientists involved in biomedical research related to DSD.

This book provides a wealth of relevant information for every endocrinologist and gynecologist who wants to broaden their knowledge of androgens in various conditions.

Download or read book Androgen Action in Prostate Cancer written by Donald Tindall and published by Springer Science & Business Media. This book was released on 2009-04-20 with total page 782 pages. Available in PDF, EPUB and Kindle. Book excerpt: Androgens are critical regulators of prostate differentiation and function, as well as prostate cancer growth and survival. Therefore, androgen ablation is the preferred systemic treatment for disseminated prostate cancer. Androgen action is exerted in target tissues via binding the androgen receptor (AR), a nuclear receptor transcription factor. Historically, the gene expression program mediated by the AR has been poorly understood. However, recent gene expression profiling and more traditional single-gene characterization studies have revealed many androgen-regulated genes that are important mediators of androgen action in both normal and malignant prostate tissue. This book will focus on the androgen-regulated gene expression program, and examine how recently identified androgen-regulated genes are likely to contribute to the development and progression of prostate cancer. Recent studies that have attempted to unravel how these genes are deregulated in androgen depletion independent prostate cancer will be included

Download or read book Testosterone written by Susan Nieschlag and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: New developments in testosterone therapy are summarized here by internationally renowned experts. They review both basic and clinical knowledge in fourteen chapters. The book begins with the biochemistry of testosterone, its biosynthesis, metabolism and mechanisms of action in target organs. Three chapters deal with specific aspects of testosterone action, namely its role in spermatogenesis, its psychotropic effects and its effects on bones. Syndromes caused by androgen resistance are described in order to highlight the importance of properly functioning enzymes and receptors in the target organs. Causes and symptoms of male hypogonadism, the major indication for testosterone treatment, are described. Five chapters are devoted to the pharmacology, pharmacokinetics and clinical uses and abuses of testosterone preparations. The new transdermal testosterone application is described in detail. Side effects of testosterone treatment are reviewed. The possible role of androgens in the development of prostatic hypertrophy and carcinoma is discussed extensively since this question is of major concern to the clinician.
