Epigenetics is a rapidly expanding field in medical and biological research which concerns heritable traits that are not attributable to changes in the DNA sequence. Epigenetic mechanisms play key roles in many biological processes, and it has become clear that their disruption can gives rise to diverse pathologies in humans. Edited by preeminent experts, Sophie Rousseaux and Saadi Khochbin, this volume in the Epigenetics and Human Health' series discusses the role of epigenetics in human reproduction. The book presents epigenetic transitions that are important at defined stages of gametogenesis and during meiosis. Several of the sixteen chapters written by experts in the field cover fundamental concepts discovered through cellular and biochemical work and from research on animal models. In other chapters, key examples are provided of how disruption of these mechanisms affects germ cell development and fertility, and contributes to the germinal cancers. Finally, the book discusses how in vitro manipulation and culture in assisted reproduction can epigenetically perturb germ cells, and how this can trigger disease phenotypes in the next generation. Conceived towards advanced students, medical professionals and research scientists, this is the first comprehensive textbook on this topic that will serve as a valuable reference during the years to come.
Providing the latest evidence-based information on etiology, evaluation and treatment, this unique text provides an in-depth, comprehensive discussion of the epidemiology, genetic and endocrinologic factors and medical and surgical management of recurrent pregnancy loss (RPL). Taking a multidisciplinary approach including psychological treatment and patient perspectives, all aspects of current RPL prevention and treatment are elucidated. Detailed chapters provide real-world illustrative material and cover the set-up and management of RPL clinics and databases, containing practical tips. Recurrent Pregnancy Loss will be an excellent resource for OB-GYN specialists, general and reproductive endocrinologists, radiologists, hematologists, psychiatrists, psychologists, and any other investigators or clinicians treating patients confronted with this emotionally and physically trying condition.
In the last forty years anthropologists have made major contributions to understanding the heterogeneity of reproductive trends and processes underlying them. Fertility transition, rather than the story of the triumphant spread of Western birth control rationality, reveals a diversity of reproductive means and ends continuing before, during, and after transition. This collection brings together anthropological case studies, placing them in a comparative framework of compositional demography and conjunctural action. The volume addresses major issues of inequality and distribution which shape population and social structures, and in which fertility trends and the formation and size of families are not decided solely or primarily by reproduction.
Biological rhythms time the ebb and flow of virtually every physiological process, and their mutual coordination guarantees the integrity of the organism over space and time. Aging leads to the disintegration of this coordination, as well as to changes in the amplitude and/or frequency of the underlying rhythms. The results of this are accelerated loss of health during aging, and in experimental model systems curtailed lifespan occurs. This book will examine the machinery that constitutes circadian systems and how they impact physiologic processes. It will also discuss how disturbances of circadian rhythms can lead to complex diseases associated with aging. Much of this treatment will focus on metabolism and genome stability. Importantly, the chapters in this book will encompass work in several different models, in addition to human. The book will conclude with a discussion of modeling approaches to biologic cycles and chronotherapy, for future research and translation.
Across the life course, new forms of community, ways of keeping in contact, and practices for engaging in work, healthcare, retail, learning and leisure are evolving rapidly. Breaking new ground in the study of technology and aging, this book examines how developments in smart phones, the internet, cloud computing, and online social networking are redefining experiences and expectations around growing older in the twenty-first century. Drawing on contributions from leading commentators and researchers across the world, this book explores key themes such as caregiving, the use of social media, robotics, chronic disease and dementia management, gaming, migration, and data inheritance, to name a few.
'Reprogen-ethics and the future of gender' bring together three tightly related topics, which have so far been dealt separately in bioethics: assisted reproduction, enhancing and gender. Part one in this book targets presents policies and legislature of assisted reproduction. Part two focuses on current views of the ethics of PGD and enhancing. Part three tackles the future of gender. Part four deals with artificial wombs and ectogenesis. The aim of this book is to provide a joint perspective in order to get the big picture. Contributors include John Harris, Matti Hairy, Tuija Takala, Soren Holm, David Heyd, Daniel Callahan, James Hughes, Harriet Bradley, Ekaterina Balabanova, Roy Gilbar and others. Some chapters in this book will significantly contribute to the current discussion of the topics at stake; other chapters will start a discussion on issues that have not yet been discussed. 'Reprogen-ethics and the future of gender' will certainly appeal to readers who are interested in any of the intersecting topics of assisted reproduction, genetic enhancing and gender; bioethicists, sociologists, genetic counsellors, gynaecologists, legislators, and students of the relevant disciplines.
Biogerontologists are now in a position to construct general principles of aging, and genuine attempts are being made to test and develop effective means of intervention, prevention and treatment of age-related diseases, and for achieving healthy old age. This book takes status of the molecular, cellular, hormonal, nutritional and lifestyle strategies being tested and applied. It comprises inter-dependent chapters written in the form of critical reviews by the world's leading researchers and practitioners in their respective fields. The format of the articles is a semi-academic style in which research data from various experimental systems is presented while focusing on their applications in human beings with respect to the prevention and treatment of age-related impairments.
The lipids of cellular membranes not only serve roles in controlling the structure and fluidity of the membrane, but are increasingly recognized for their roles as signalling molecules and modifiers of membrane protein function. Recent studies described in this volume reveal striking changes in membrane lipids during aging and in age-related diseases such as cancer, cardiovascular disease and neurodegenerative disorders. Lipids including inositol phospholipids, cholesterol, sphingolipids and ceramides play important roles in signalling cellular responses to stress and specific stimuli such as growth factors, cytokines and neurotransmitters. One or more of these lipid mediators has been linked to the pathogenesis of age-related diseases.
Based on an intensive qualitative study of a diverse group of 51 older widowers, this unique book sets widowhood within the context of life experience and identifies characteristics and patterns of behaviour that contribute to widowers' success, or lack of it, in adjusting satisfactorily to their circumstances. The authors shed light on widowers' specific needs and on the services needed to help widowers develop greater self-reliance. Among the topics discussed are models of resilience, marriage and illness of the spouse, caregiving and communication, death of the wife, grief and adjustment, living alone and remarriage, life values carried forward, adult children and other social support, and cohorts and the future. The authors conclude with a consideration of trends that may influence the next generation's experience of widowhood. This excellent volume offers expert guidance on the needs and care of the nearly invisible population of older widowers.
This book is an an up-to-date survey and summary of present knowledge and future expectations regarding the environmental causes of congenital malformations in human beings, beginning with the earliest discoveries of the 20th century up to the latest ideas and problems at its end, presents views and comments on the progress made over the century in understanding human prenatal maldevelopment.
Infertility and assisted reproductive technologies in India lie at the confluence of multiple cultural conceptions. These 'conceptions' are key to understanding the burgeoning spread of assisted reproductive technologies and the social implications of infertility and childlessness in India. This longitudinal study is situated in a number of diverse locales which, when taken together, unravel the complex nature of infertility and assisted conception in contemporary India.
This volume provides a timely and thorough review of the current state of understanding of a fascinating type of cell that is capable of forming many or all cells in the body. In humans and other mammals embryonic stem cells, the immediate offspring of the fertilized egg, are capable of forming any type of cell in the body. Moreover stem cells are present in many different tissues in adults that are capable of dividing and differentiating into the specific cell types that comprise the organ in which they reside.
This book will be a valuable reference for developmental
biologists and for scientists and clinicians who study and treat a
variety of diseases.
The processes of aging and death remain one of the most fascinating, and mysterious, areas of biological research. Huge anomalies between species raise questions the answers to which could have fundamental implications for the field of medical science. As scientists unlock the secrets of the exceptionally long-lived little brown bat (up to 34 years), or the common budgerigar, for example, which despite having a metabolic rate 1.5 times that of a laboratory mouse, can live for up to 20 years, it has become more important than ever to be able to make a comparative analysis of the various species used in research. Dealing with every one of the mammalian species that are employed in laboratory research, this is the first book on the subject of aging that provides detailed comparative data for age-related changes in its subjects. It does so at the level of the whole animal, its organs, organelles and molecules. The comparative data, supplied in 15 chapters by leading experts, provides information on fields as disparate as telomere function and loss, the importance of the Sirtuins and Tor, the influence of hormones on lifespans, the relationship between body size and lifespan, the effects of restricted calorific intake, age-related changes in cell replication, and DNA damage and repair. Chapters are devoted to cardiac aging, comparative skeletal muscle aging, the aging of the nervous and immune systems, the comparative biology of lyosomal function and how it is affected by age, and many other key areas of research. This much-needed text will provide scientists working in a wide spectrum of fields with key data to aid them in their studies.
The world's population is growing at an unsustainable rate. From a baseline ?gure of one billion in 1800, global population is predicted to exceed nine billion by 2050 and 87. 8% of this growth will be localized in less developed countries. Such uneven population growth will yield a harvest of poverty, malnutrition, disease and en- ronmental degradation that will affect us all. Amongst the complex mixture of political, social, cultural and technological changes needed to address this issue, the development of improved methods of fertility regulation will be critical. The inadequacy of current contraceptive technologies is indicated by recent data s- gesting that the contraceptive needs of over 120 million couples go unmet every year. As a direct consequence of this de?cit 38% of pregnancies are unplanned and more than 50% end in an abortion, generating a total of 46 million abortions per annum particularly among teenagers. If safe, effective contraceptives were ava- able to every couple experiencing an unmet family planning need, 1. 5 million lives would be saved each year (UNFPA 2003). Progress in contraceptive technology should not only generate more effective methods of regulating fertility, but should also provide a range of methods to meet the changing needs of the world's population. Contraceptive practice was revo- tionized in 1960 in the US and 1961 in Europe by the introduction of the oral contraceptive pill by Gregory Pincus, MC Chang and colleagues, based on fun- mental hormone research conducted in Germany.
For counselor Nancy Wainer Cohen, this book is the sibling to "Silent Knife: Cesarean Prevention and Vaginal Birth after Cesarean "(Bergin & Garvey, 1983) her critically-acclaimed expose on America's growing reliance on cesarean sections. "Open Season "provides fresh insights and new information on the subject, offering guidance to childbearing couples, educators, health professionals, and scholars who value the natural path of childbirth. Readers will find this book timely, informative, shocking, irreverent, and extremely readable. Cohen's intimate writing style presents a compendium of knowledge on childbirth in the fashion of a personal letter. Her aim is to lower America's alarming reliance on cesarean section, which is currently at 25 percent of all births, and to return the responsibility for childbirth to women by encouraging them to choose the kind of birthing experience they wish to have. In addition to cesarean section, Cohen discusses many other generally unnecessary interventions performed on women during pregnancy and childbirth--such as fetal monitoring and routinized hospital procedures.
The over-arching goal of this volume is to help infertility practitioners evaluate and manage their patients with poor semen quality. The authors review the existing literature on the effects of medications on male fertility, and provide detailed information about what is known, giving the number of individuals and population characteristics for studies of medication effects on male fertility. Medications are designed to treat illness and reduce symptoms, but all have undesirable adverse effects such as headache or stomach upset. Some adverse reactions can even be life-threatening, so it is no surprise that some drugs have negative effects on male reproduction. Medical practitioners rarely consider a man's reproductive plans when prescribing medications. Men are routinely treated with drugs that can impair or abolish fertility. Although practitioners in the field of reproductive medicine generally realize that certain drugs impact negatively on reproductive health, there are limited resources providing evidence-based knowledge useful in counseling patients. Tables throughout this volume summarize the information for each drug, providing a handy reference for clinical use.
How and to what extent have Islamic legal scholars and Middle Eastern lawmakers, as well as Middle Eastern Muslim physicians and patients, grappled with the complex bioethical, legal, and social issues that are raised in the process of attempting to conceive life in the face of infertility? This path-breaking volume explores the influence of Islamic attitudes on Assisted Reproductive Technologies (ARTs) and reveals the variations in both the Islamic jurisprudence and the cultural responses to ARTs.
In recent years, the advancing science and increasing availability of assisted reproduction have given new hope to infertile couples. However, the use of IVF and ART has also led to marked increases in the number of multiple-infant live births. This poses a public health concern, as these neonates have a higher rate of pre-term delivery, compromising their survival chances and increasing their risk of lifelong disability. By optimizing the selection of gametes and embryos with high probabilities of implantation, it is possible to reduce the number of embryos transferred and, by extension, the number of high-risk multiple gestations, while maintaining or increasing pregnancy rates. Human Gametes and Preimplantation Embryos: Assessment and Diagnosis provides a broad yet concise overview of established and developing methodologies for assessment of gamete and embryo viability in assisted reproduction. This book elucidates the best practices for precisely selecting viable specimens based on morphology and cleavage rate and covers the spectrum of emerging adjunctive technologies for predicting reproductive potential. The authors present their extensive knowledge of "omics" approaches (genomics, transcriptomics, proteomics, and metabolomics), with unbiased delineation of the associated advantages and potential pitfalls. This valuable clinical resource is well suited to infertility specialists, Ob/Gyn physicians, IVF laboratory technicians, and researchers in the fields of embryology and reproductive medicine.
Stress is a double edged sword. Whereas chronic stress has well known harmful effects, recent research shows that intermittent exposure of cells and organisms to mild stress can improve various biological parameters, including severe stress tolerance, health span and longevity. Mild stress-induced hormesis is potentially a powerful tool in gerontological research and interventions. This book brings together some of the world leaders in this area of research who present a critical analysis of the ongoing research with respect to the effects and mechanisms of action of various types of mild stress, such as irradiation, heat, physical exercise, hypergravity, pro-oxidants and nutritional components, on a variety of biological systems ranging from fruitflies to human cells and bodies. Their separate chapters and a final collective chapter open up a whole new world of possibilities for future research in aging, successful aging, and health span extension.
Since the late 1960s, there has been an acceleration of research focused on understanding how the efferent ducts, the epididymis, and the vas deferens function with respect to the maturation and storage of spermatozoa and as hormone dependent tissues. Another major interest in the epididymis is that it is an attractive target for the development of male contraceptives. There are well over 16,000 peer reviewed articles in the literature on these tissues, their structure, gene expression, protein synthesis and function. Regular international meetings have been initiated that are dedicated to this field. Thus, there is an urgent need for a comprehensive reference volume that spans every facet of epididymal biology, from historical background to the most current results, from basic cell and molecular biology to clinical issues. Well-established experts from every part of the world have contributed to this volume. By necessity, each author was given page limitations so that many topics are not dealt with exhaustively. Whenever possible, references to more comprehensive discussion of specific topics are included.
Gender, Identity and Reproduction draws on a variety of perspectives relevant to an understanding of reproduction across the life-course. Through a consideration of the representation of reproductive identities and experiences, the book highlights difference and diversity in relation to contemporary reproductive choices. The book focuses on women's and men's experiences of agency, control and negotiation within the context of cultural, medical, political, theoretical and lay ideologies of the reproductive process in contemporary Western societies.
It has been over 40 years since the original report by Salmon and Daughaday demon strating that the ability of GH to stimulate sulfation of cartilage was mediated by a "sulfation factor. " In the ensuing decades, it has become apparent that this "sulfation factor activity" encompasses a complex system ofligands (IGFs), receptors, and carrier proteins that are, in tum, responsible for a wide array of cellular actions. The IGF system has been demonstrated to be critically involved in both intrauterine and postnatal growth, and to have important implications in cancer biology as well, owing to the ability of the IGFs to function in endocrine, paracrine, and autocrine modes and given the wide distri bution of IGFs in virtually every organ system. The contributions to The /GF System reflect the wide span of interest in the IGF system and its implications for normal and abnormal growth and metabolism. The chapters have been divided into four broad sections: I. Molecular biology of the IGF system; II. Bio logical actions of the IGFs; III. IGF physiology; and IV. Clinical aspects of the IGFs. We have made every effort to highlight the major contemporary themes in IGF biology, but as is inevitable in such a fast-moving field, perspectives will continue to change as new information is accumulated."
Drawing on a wide range of interviews and primary and secondary sources, this book investigates the dynamic interactions between national regulatory formation and the global biopolitics of regenerative medicine and human embryonic stem cell science.
In this second volume, the Biennial Review of Infertility brings together the most up-to-date research and clinical information on male and female infertility, emerging assisted reproductive techniques, and controversial issues in reproductive medicine. This volume includes discussion of cutting-edge topics such as epigenetics, proteomics, and the role of the environment in fertility, as well as insightful evidence-based discussion of common clinical procedures. It is the cumulative effort of a preeminent panel of experts presenting each chapter in a clear and well-balanced manner. Created to provide an ongoing appraisal of current knowledge, the Biennial Review of Infertility stimulates communication amongst all those working to help couples resolve their infertility. |
