Book Synopsis Cell and Molecular Biology of the Testis by : Claude Desjardins
Download or read book Cell and Molecular Biology of the Testis written by Claude Desjardins and published by Oxford University Press, USA. This book was released on 1993 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive, multi-authored work on the structure and function of the mammalian testis. The approach emphasizes gene expression, translation and production of specific gene products and the cellular and molecular regulation of these fundamental processes. Rather than provide a global survey of all aspects of male reproduction, this book stresses specific mechanisms that underscore the structure and function of the testis. It explains old and new concepts from a cellular and molecular perspective. This novel approach allows the authors to forge links between cell and molecular biology and well-established aspects of spermatogenesis and steroidogenesis. The result is a well-focused, comprehensive, and synthetic analysis of testicular biology.

Book Synopsis Testicular Tangrams by : Focko Rommerts
Download or read book Testicular Tangrams written by Focko Rommerts and published by Springer Science & Business Media. This book was released on 2002-04-03 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past two decades research on the testis has created a vast number of publications. New techniques, such as cell and gene clon ing, germ cell manipulation and transplantation, as well as gene ex pression, have surpassed the classical approaches that involved studies on receptor activation and endocrine, paracrine and autocrine regula tory mechanisms. Due to the expansion of this field of research it has become increasingly difficult to integrate the large number of observa tions and relate them to the physiology and pathophysiology of the tes tis. More emphasis must, therefore, be put on the integration of isolated findings and the construction of the total picture. In order to stimulate this specific mental activity we have named this book Testicular Tan gram. We hope that the chapters in this book will be used as pieces of the testicular puzzle and that the reader enjoys composing new shapes. The chapters of this book are representative of the plenary lectures presented at the I ih European Workshop on Molecular and Cellular Endocrinology of the Testis held in Doorwerth The Netherlands, from April 6 - I 0, 2002. Publication of this book has been made possible by the generous support of the Ernst Schering Research Foundation. We would also like to thank the distinguished scientists, who have pro vided us with their excellent manuscripts well before the start of the Workshop. We acknowledge the help of Dr. U. -F. Habenicht, Dr. M.

Book Synopsis Genetics of Human Infertility by : P.H. Vogt
Download or read book Genetics of Human Infertility written by P.H. Vogt and published by Karger Medical and Scientific Publishers. This book was released on 2017-09-12 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infertility affects more than one in ten couples worldwide and is related to highly heterogeneous pathologies sometimes only discernible in the germ line. Its complex etiology often, but not always, includes genetic factors besides anatomical defects, immunological interference, and environmental aspects. Nearly 30% of infertility cases are probably caused only by genetic defects. Thereby experimental animal knockout models convincingly show that infertility can be caused by single or multiple gene defects. Translating those basic research findings into clinical studies is challenging, leaving genetic causes for the vast majority of infertility patients unexplained. Nevertheless, a large number of candidate genes have been revealed by sophisticated molecular methods. This book provides a comprehensive overview on the subject of infertility written by the leading authorities in this field. It covers topics including basic biological, cytological, and molecular studies, as well as common and uncommon syndromes. It is a must-read for human geneticists, endocrinologists, epidemiologists, zoologists, and counsellors in human genetics, infertility, and assisted reproduction.
Book Synopsis Exploring the Biological Contributions to Human Health by : Institute of Medicine
Download or read book Exploring the Biological Contributions to Human Health written by Institute of Medicine and published by National Academies Press. This book was released on 2001-07-02 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's obvious why only men develop prostate cancer and why only women get ovarian cancer. But it is not obvious why women are more likely to recover language ability after a stroke than men or why women are more apt to develop autoimmune diseases such as lupus. Sex differences in health throughout the lifespan have been documented. Exploring the Biological Contributions to Human Health begins to snap the pieces of the puzzle into place so that this knowledge can be used to improve health for both sexes. From behavior and cognition to metabolism and response to chemicals and infectious organisms, this book explores the health impact of sex (being male or female, according to reproductive organs and chromosomes) and gender (one's sense of self as male or female in society). Exploring the Biological Contributions to Human Health discusses basic biochemical differences in the cells of males and females and health variability between the sexes from conception throughout life. The book identifies key research needs and opportunities and addresses barriers to research. Exploring the Biological Contributions to Human Health will be important to health policy makers, basic, applied, and clinical researchers, educators, providers, and journalists-while being very accessible to interested lay readers.
Book Synopsis Testicular Chromosome Structure and Gene Expression, Volume 1120 by : E. Mitchell Eddy
Download or read book Testicular Chromosome Structure and Gene Expression, Volume 1120 written by E. Mitchell Eddy and published by Wiley-Blackwell. This book was released on 2007 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2005 Workshop, published as volume 1061 of the Annals, focused on testicular cell dynamics and brought an influx of new information into the field of male reproduction. Several laboratories have been actively investigating the endocrine signals between the germ and somatic cells of the testis, revealing previously unknown patterns of cell signaling and cell-to-cell communication in male reproductive tract tissues. Work in this area will provide an opportunity to analyze male reproductive biology and the processes by which sperm are formed in the seminiferous tubule and androgen is synthesized in the interstitium of the testis. The different levels of organization in the testis, including the stages of spermatogenesis, enzymatic steps of steroidogenesis and the intracellular signaling pathways of hormones, are now more amenable for study and selection of potential targets for drug development. Capitalizing on these developments, the editors of this volume have chosen a roster of chapter contributors that is uniquely suited to stimulate research and development ideas among readers.

Book Synopsis Testis Cancer: Genes, Environment, Hormones by :
Download or read book Testis Cancer: Genes, Environment, Hormones written by and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Testicular cancer (TC) is the most common cancer in males aged 20-40 years, with a worldwide incidence of 7.5 per 100,000, but the rates vary considerably between countries and ethnic groups and there is evidence also for an increasing incidence in last decades. About 95% of all TCs are represented by testicular germ cell tumors (TGCTs), which include seminoma and non-seminoma histological types. It is generally assumed that the development of TGCT is under endocrine control. In particular, unbalanced androgen/estrogen levels and/or activity are believed to represent the key events for TGCT development and progression. Furthermore, recent evidence has suggested genetic association of TGCT with variations in genes involved in hypothalamic-pituitary-testicular axis and steroidogenic enzymes. This recent evidence expands the current knowledge on the role of genetic contribution in testicular cancer susceptibility, and supports the hypothesis that variations in hormone metabolism genes might change the hormonal environment implicated in testicular carcinogenesis. Therefore, hormonal carcinogenesis is an important and controversial area of current research in TGCT, and further attention is given to genetic factors influencing hormone-related cancer risk. The genetic component to TGCT is in general strong. In fact, although environmental factors clearly contribute to TGCT development (and probably to its increasing incidence in some geographical areas), the proportion of TGCT susceptibility accounted for by the genetic effects is estimated at 25%. TGCT has high familial risks compared with most other cancer types that are generally no more than two-fold: brothers of individuals with TGCT have an 8- to 12-fold increased risk of disease, and sons of affected individuals have a 4- to 6-fold increased risk. Despite this strong familial relative risk, early results from linkage studies identified a limited relationship with genetic factors, suggesting that TGCT is a genetically complex trait. However, more recently, four genome-wide association studies (GWAS) from the UK and USA have reported association of TGCTs with six new loci (KITLG, SPRY4, BAK1, DMRT1, TERT, and ATF7IP). The strongest association for TGCT susceptibility was found for SNPs in KITLG (ligand for the membrane-bound receptor tyrosine kinase KIT) gene with a greater than 2.5-fold increased risk of disease per major allele, which is the highest reported for any cancer to date. These studies are being now replicated by other researches and attention is given to the relationship between these genetic variations, TGCT risk and frequently associated anomalies of the reproductive tract, such as cryptorchidism and infertility. Finally, over the past few decades, TCGT research has focused also on external environmental causes acting mainly as endocrine disrupters of androgen and oestrogen pathways, even during the foetal development of the testis. It is well known that the testicular dysgenesis syndrome (TDS) hypothesis, proposed ten years ago, suggests that disturbed testicular development in fetal life may result in one or more of four disorders postnatally, named cryptorchidism, hypospadias, poor semen quality, and TGCT. These four disorders are therefore considered as one clinical entity and are linked together by epidemiological and pathophysiological relations. The relative contribution of genetics and environment in TGCT development, and the interactions between endocrine disruptors and variations in genes involved in hormonal carcinogenesis is therefore another interesting area of research.

Available in PDF, EPUB and Kindle. Book excerpt: Natural selection operates among individual organisms which differ in their genetic constitution. The degree of hereditary variability within a species is greatly enhanced by cross-fertilization. Indeed, the mechanism of sexual reproduction occurred very early in evolution, for it is seen today even in bacteria. In Escherichia coli, fertilization occurs by passage of the single chromosome from the male into the female bacterium (LEDERBERG, 1959). In multicellular organisms, the separation of germ from soma, and the production of haploid gametes became mandatory. The gametes were of two types. One, extremely mobile, was designed to seek out and penetrate the other, which loaded with nutrients, received the mobile gamete and intiated the development of a new individual. The foundation for true bisexuality was thus laid. In the primitive state of bisexuality, whether an individual is to be a sperm-producing male or an egg-producing female appears to be decided rather haphazardly. In the worm, Banelia viridis, the minute males are parasites in the female. Larvae that become attached to the proboscis of an adult female become males, while unattached larvae sink to the bottom and become females (BALTZER, 1935). The more sophisticated state of bisexuality was initiated by setting aside a particular pair of chromosomes for specialization and making either the male or the female a heterogametic sex. Sex chromosomes as we know them were thus born.

Book Synopsis The Testicular Descent in Human by : K.J. Barteczko
Download or read book The Testicular Descent in Human written by K.J. Barteczko and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The testicular descent (descensus testis) is described in a complete series of human material from stage 14 CC to the adult state by using own phases. Central points of interest in this work are answers to questions which have been discussed controversially by generations of scientists and which are wrong or inadequately documented in most textbooks of embryology: Does an inner gonadal descent exist? What about origin, role and fate of gubernaculum H., processus vaginalis peritonei and gonadal ligaments? How do the annexes of testis come into their final position? The results are based on serial sections, scanning electron microscopy, three-dimensional reconstructions, microdissection and immunohistochemistry.
