Most of the following chapters were presented as plenary lectures or symposium talks at the 1986 XXXth Congress of the International Union of Physiological Sciences in Vancouver, B.C. A distinguished international group of endocrinologists and physiologists have contributed up-to-date reviews of their particular fields. The early chapters are largely concerned with the brain and neuroendocrine mechanisms controlling the secretion of gonadotropin releasing hormone (GnRH) and its action on the anterior pitui- tary gland. Later chapters focus on the gonads themselves and the systemic and intrinsic hormones influencing the functional cytology of ovarian and testicular cells. Such comprehensive subjects as sex differentiation, puberty, placentation and parturition are also discussed authoritatively. According to Pfaff and Cohen and Arai et al., gonadal steroids, especially estrogen, exert multiple effects on certain hypothalamic and preoptic neurons, including growth, protein synthesis and electrical changes, which promote plasticity and facilitate synaptogenesis. The electrophysio- logy of the hypothalamic GnRH pulse generator in the rhesus monkey is reviewed more specifically by Knobil. In ovariectomized ewes, Clarke finds both positive and negative effects of estrogen on hypothalamic release of GnRH as well as on pituitary responsiveness to the peptide. Flerk6 et al.

To celebrate the Center for Perinatal Biology s 40th Anniversary, an illustrious group gathered at Loma Linda University in February 2013. That gathering of experts and this volume of the proceedings are a tribute to the founder of the Center, Lawrence D. Longo, M.D. These chapters present contributions from individuals who in some way or another were influenced by Dr. Longo. Covering a wide range of topics, and illustrating the diversity of thinking and scientific interests, these proceedings address basic science through to clinical problems in the developmental programming of health and disease.

This volume is one of the first to concentrate on positive growth and development in a clinical arena, rather than loss and pathology. In contrast to the general theories and cross-sectional studies of existing adult developmental research, much of this volume looks at the whole-life level of development of adults through case studies. The book unites three compatible approaches to the study of adult development. The first considers the development of whole life. The second approach examines behavior during certain periods in adults' lives by combining clinical and developmental stage perspectives. The third approach examines periods of life following the work of Erikson, Levinson, and Vaillant. The editors of this volume believe that these three approaches form, in their synergy, a comprehensive and multifaceted approach to uniquely difficult problems of late adolescence and early adulthood. It is the unification of these three approches that makes this book unique in its field.

Carl Edward Sagan's (1934-1996) one of the famous quotation was "Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people." From past to date, well-known molecules, enzymes, proteins, lipids and carbohydrates are studied in the pathogenesis of several diseases both as a diagnostic/prognostic biomarker and therapeutic agent. The underlying mechanism of unexplained diseases and failure of therapies are frequently studied with well-known biomarkers, but remain unclear in many cases. As Dr. Sagan said other keys are still waiting to be known in some forgotten corner of a body universe, we find strength to propose that one of them can be the growth factor with cytokine activity named "Midkine" This book summarizes the extensive up-to-date literature overeview with the lastest work of experts about midkine in a detailed format that conveys its role as both a pathologic factor and therapeutic agent.

Although breast-feeding has long been associated with lowered infant morbid- ity and mortality from infectious disease, until relatively recently little was known regarding the individual components of human milk aside from their nutritive func- tions and the presence of secretory antibodies. Over the last 40 years, and especially over the last decade, evidence has been growing that human milk contains a large number of materials that are bioactive and that are not found in artificially formu- latedinfantdiets. Disparatelinesofresearcharecurrentlyproducingsurprisinglylong listsofnewlyrecognizedhumanmilkcomponents-antimicrobialsand immunomod- ulators, includinganti-inflammatoryagents, antioxidants, cytokines, andhormones- with biological activities that relate to pathogenesis, inflammation, development, metabolic regulation, and other functions. The sum of all of these biologically active milk components may account for the strong protection that human milk affords nursing infants. Strictly speaking, most components of human milk could be considered bioac- tive, since nutrients are bioactive by definition. A major emphasis of this book, how- ever, is on defining what is known about components of human milk that inhibit common pathogens of the infant, those that have hormonal and/or cytokine activity, those that have immunomodulatory and/or anti-inflammatory activity, xenobiotics, and nutrients that are uniquely essential to early development. The topic of bioactive substances in human milk was explored in depth at the th 8 International Conference of the International Society for Research on Human Milk and Lactation (ISRHML) held at Plymouth, Massachusetts, October 25-29, 1997. This book contains the proceedings of that conference.

Distinguished physicians critically review the clinical consequences of the endocrinological changes that occur with aging-in both men and women-and examine the use of hormonal therapy to reduce them. Topics range from bone disease and water balance in all older people, to androgen deficiency in aging males, gynecomastia, and menopause. The authors also discuss Type II diabetes in persons over 65, emphasizing the cognitive benefits of good glycemia control, and the interaction of nutrition and metabolism, focusing on hypocholesterolemia, obesity, the anorexia of aging, trace elements, and vitamins. The aging of the sympathetic nervous system and its impact on hypertension in the elderly is also covered. Timely and authoritative, Endocrinology of Aging offers endocrinologists, geriatricians, and primary care physicians critical insight into the endocrine problems of our rapidly growing elderly population.

Recent studies have indicated that epigenetic processes may play a major role in both cellular and organismal aging. These epigenetic processes include not only DNA methylation and histone modifications, but also extend to many other epigenetic mediators such as the polycomb group proteins, chromosomal position effects, and noncoding RNA. The topics of this book range from fundamental changes in DNA methylation in aging to the most recent research on intervention into epigenetic modifications to modulate the aging process. The major topics of epigenetics and aging covered in this book are: 1) DNA methylation and histone modifications in aging; 2) Other epigenetic processes and aging; 3) Impact of epigenetics on aging; 4) Epigenetics of age-related diseases; 5) Epigenetic interventions and aging: and 6) Future directions in epigenetic aging research.

The most studied of epigenetic processes, DNA methylation, has been associated with cellular aging and aging of organisms for many years. It is now apparent that both global and gene-specific alterations occur not only in DNA methylation during aging, but also in several histone alterations. Many epigenetic alterations can have an impact on aging processes such as stem cell aging, control of telomerase, modifications of telomeres, and epigenetic drift can impact the aging process as evident in the recent studies of aging monozygotic twins.

Numerous age-related diseases are affected by epigenetic mechanisms. For example, recent studies have shown that DNA methylation is altered in Alzheimer s disease and autoimmunity. Other prevalent diseases that have been associated with age-related epigenetic changes include cancer and diabetes. Paternal age and epigenetic changes appear to have an effect on schizophrenia and epigenetic silencing has been associated with several of the progeroid syndromes of premature aging. Moreover, the impact of dietary or drug intervention into epigenetic processes as they affect normal aging or age-related diseases is becoming increasingly feasible.

This book focuses on precocious puberty, providing a unique continuum of expertise looking at puberty from anthropologic, epidemiologic, clinical, and molecular perspectives. The volume addresses broad pubertal changes in the general population while at the same time providing in depth information about specific disorders of puberty and the latest management changes. In particular, the book is intended for endocrinologists and internists.

In dealing with recent advances in biological engineering and human reproduction, we are confronted with legal, ethical, and religious questions for which there are no precedents. Warren Freedman undertakes a comprehensive examination of this topic. Sorting through the tangle of issues surrounding artificial insemination, surrogate motherhood, and other aspects of contemporary reproduction trends, Freedman attempts to clarify the rights and responsibilities of individuals, families, and society in the face of these new developments.

The author begins with a survey of the legal implications of nontraditional approaches to conception and birth. Separate chapters are devoted to artificial insemination and surrogate motherhood; and new concepts such as cryo-preservation, in-vitro fertilization, banking of sperms and eggs, and patentable new organisms are also discussed in detail. The author addresses questions of rights and liabilities as they apply to fetuses, donors, and adoptive parents, as well as the role of physicians and parenthood organizations, researchers, corporations, and government. Following a review of existing statutes, policies, and contracts that attempt to deal with these issues both here and abroad, he presents proposals that may aid in achieving equitable, uniform solutions. Freedman's book will be of interest to any citizen, group, or government agency concerned with these vital questions, and to professionals in law, government, medicine, human services, and industry.

Teratology is the study of chemical-induced birth defects. This book is a comprehensive guide to the procedures and methods commonly employed in the safety testing of all classes of chemical for teratogenicity (also referred to as embryotoxicity, developmental toxicity or prenatal toxicity). The various international regulatory requirements are explained in detail, in order that the reader may perform all of the necessary studies for the successful registration or marketing authorisation of a new pharmaceutical, industrial chemical, crop protection product or food additive. Written in the highly successful Methods in Molecular Biology (TM) series format, each chapter gives clear complete instructions on how to perform the task in hand. The authors are respected experts in their field, all with hands-on experience of the procedures described. Teratogenicity Testing: Methods and Protocols gives crucial guidance and tips on how to deal with unexpected results and overcome regulatory difficulties.

Advances in technology now offer promising solutions to deal with the chronological aging of the cell, tissue or organ to synchronize its existence and its use. This book covers the developments in and benefits of the latest vitrification technology and its extensive applications in reproductive medicine. Protocols of gametes (oocyte and sperm), embryos, blastocysts and ovarian tissue cryopreservation have been reviewed by leaders in the field. In order to address the escalation in cross-border reproductive tourism entailing the transfer of reproductive cells and tissues rather than the patient, the challenges, caution and emerging possibilities of nitrogen vapor shipment of vitrified cells have been discussed. Current perspectives on oocyte banking present the reader with options and solutions to effectively utilize these gametes despite the physiological deterrents.The versatile applications and potential of vitrification of human embryonic stem cells, discussed in the concluding chapter, is an exciting reality offered by vitrification to help overcome numerous stumbling blocks in the management of various disorders.

This atlas comprises a complete and extensive exposure of the spatial and temporal aspects of human cardiac development as seen with scanning electron microscopy. Apart from serving as a unique overview on cardiac development in the human embryo, this atlas gives an updated morphological reference of cardiac embryology for topographic correlation and enables the projection of experimental results in animals to the human situation.

The editor of this volume takes on the challenging task of presenting an encompassing view of childbirth in America from an anthropological perspective. The book is indeed comprehensive. . . . Collectively the chapters in Childbirth in America lay out a representative sketch of research problems of interest to sociocultural anthropologists and other social scientists working in the area of reproductive health. A distinct accomplishment is the acknowledgement in some of the chapters that not all American women want the same kind of childbirth care or have the same values and attitudes about pregnancy, birth, and parenting, and that this variation needs addressing in both childbirth policy and practice. American Journal of Physical Anthropology A comprehensive and critical examination of the experience of childbirth in America today, from pregnancy to early postpartum. This book covers many controversial issues in the context of diverse cultural, social, and economic backgrounds, which have arisen as a result of the new technologies and ideologies surrounding pregnancy and birth. Most useful as a text for courses in childbirth education, anthropology of women's health, and anthropology of medicine.

Arthur L. Caplan It is commonly said, especially when the subject is assisted reproduction, that medical technology has out stripped our morality. Yet, as the essays in this volume make clear, that is not an accurate assessment of the situ ation. Medical technology has not overwhelmed our moral ity. It would be more accurate to say that our society has not yet achieved consensus about the complex ethical iss ues that arise when medicine tries to assist those who seek its services in order to reproduce. Nevertheless, there is no shortage of ethical opinion about what we ought to do with respect to the use of surrogate mothers, in vitro fertil ization, embryo transfer, artificial insemination, or fertil ity drugs. Nor is it entirely accurate to describe assisted repro duction as technology. The term "technology" carries with it connotations of machines buzzing and technicians scurrying about trying to control a vast array of equip ment. Yet, most of the methods used to assist reproduc tion that are discussed in this volume do not involve exotic technologies or complicated hardware. It is technique, more than technology, that dominates the field of assisted reproduction. Efforts to help the infertile by means of the manipu lation of human reproductive materials and organs date 1 2 Caplan back at least to Biblical times. Human beings have en gaged in all manner of sexual practices and manipulations in attempts to achieve reproduction when nature has balked at allowing life to begin."

In this paradigm-shifting book from acclaimed Harvard Medical School doctor and one of TIME magazine's 100 most influential people on earth, Dr. David Sinclair reveals that everything we think we know about ageing is wrong, and shares the surprising, scientifically-proven methods that can help readers live younger, longer. For decades, the medical community has looked to a variety of reasons for why we age, and the consensus is that no one dies of old age; they die of age-related diseases. That's because ageing is not a disease - it is inevitable. But what if everything you think you know about ageing is wrong? What if ageing is a disease? And that disease is curable. In LIFESPAN, Dr. David Sinclair, one of the world's foremost authorities on genetics and ageing, argues just that. He has dedicated his life's work to chasing more than a longer lifespan - he wants to enable people to live longer, healthier, and disease-free well into our hundreds. In this book, he reveals a bold new theory of ageing, one that pinpoints a root cause of ageing that lies in an ancient genetic survival circuit. This genetic trick - a circuit designed to halt reproduction in order to repair damage to the genome -has enabled earth's early microcosms to survive and evolve into more advanced organisms. But this same survival circuit is the reason we age: as genetic damage accumulates over our lifespans from UV rays, environmental toxins, and unhealthy diets, our genome is overwhelmed, causing gray hair, wrinkles, achy joints, heart issues, dementia, and, ultimately, death. But genes aren't our destiny; we have more control over them than we've been taught to believe. We can't change our DNA, but we can harness the power of the epigenome to realise the true potential of our genes. Drawing on his cutting-edge findings at the forefront of medical research, Dr. Sinclair will provide a scientifically-proven roadmap to reverse the genetic clock by activating our vitality genes, so we can live younger longer. Readers will discover how a few simple lifestyle changes - like intermittent fasting, avoiding too much animal protein, limiting sugar, avoiding x-rays, exercising with the right intensity, and even trying cold therapy - can activate our vitality genes. Dr. Sinclair ends the book with a look to the near future, exploring what the world might look like - and what will need to change - when we are all living well to 120 or more. Dr. Sinclair takes what we have long accepted as the limits of human potential and mortality and turns them into choices. THE EVOLUTION OF AGEING is destined to be the biggest book on genes, biology, and longevity of this decade.

The purpose of this third edition of Developmental and Reproductive Toxicology is to provide a practical guide to developmental and reproductive toxicology in a regulatory environment. In addition to a comprehensive update of current chapters, the third edition been revised to reflect recent changes in the field. It contains new chapters that reflect emerging topics of interest, including testing of biologics (including vaccines), nonhuman primates as nonclinical models, developmental immunotoxicity testing, in vitro assays (such as use of zebrafish and stem cells, as well as high throughput screening), in silico systems modelling, evaluating mechanisms of reproductive toxicity, in-depth coverage of neurobehavioral testing, and testing under the EU's REACH regulations, as well as updated chapters on nonclinical juvenile toxicity testing, endocrine disruptor screening, and on functional and computational genomics. The study of hazard and risk associated with exposure to toxicants during prenatal development has been expanded in recent years to include effects on development until the time of puberty. Concern over the adverse effects of chemical or physical agents on the reproductive processes of both sexes has increased, and progress has been made in identifying the causes and mechanisms eliciting congenital defects and determining the genetic, epigenetic, and environmental factors involved. This book provides up-to-date guidance on the use and interpretation of the newest research techniques in developmental and reproductive toxicology, as well as the more traditional approaches. Developmental and Reproductive Toxicology, Third Edition: Contains valuable insights gained from hands-on experience, together with a critical evaluation of current testing strategies. Includes guidance for the design, conduct, and interpretation of tests in all areas of developmental and reproductive toxicity. Contains reprinted guidelines from major regulatory agencies, as well as terminology for description of developmental abnormalities in laboratory animals, for easy reference. Provides guidance for planning and conducting preclinical toxicity studies and follow-up studies, and interpreting their results in a regulatory environment. This book continues to be the ideal practical reference for developmental and reproductive toxicologists who perform research in industry, government, and academia and for anyone who intends to enter these research areas.

"Konrad has produced an exceptionally interesting and totally original book . . . a major contribution to social theory." . Marilyn Strathern, Cambridge University Based on the author's fieldwork at assisted conception clinics in England in the mid-1990s, this is the first ethnographic study of the new procreative practices of anonymous ova and embryo donation. Giving voice to both groups of women participating in the demanding donation experience - the donors on the one side and the ever-hopeful IVF recipients on the other - Konrad shows how one dimension of the new reproductive technologies involves an unfamiliar relatedness between nameless and untraceable procreative strangers. Offsetting informants' local narratives against traditional Western folk models of the 'sexed' reproductive body, the book challenges some of the basic assumptions underlying conventional biomedical discourse of altruistic donation that clinicians and others promote as "gifts of life." It brings together a wide variety of literatures from social anthropology, social theory, cultural studies of science and technology, and feminist bioethics to discuss the relationship between recent developments in biotechnology and changing conceptions of personal origins, genealogy, kinship, biological ownership and notions of bodily integrity.

Hans-Werner Wahl, Hermann Brenner, Heidrun Mollenkopf, Dietrich Rothenbacher and Christoph Rott Ageing research has been identi?ed as a prototypical ?eld of inquiry deserving the full exploitation of single discipline approaches and interdisciplinary synergies amongst these single perspectives. Although this is a generally accepted insight, there still is a strong need to provide models of how this global and most fundamental challenge can be dealt with. It seems in any case necessary to narrow down the wide scope of ageing research issues to sets of key constructs most promising in terms of interdisciplinary cross-fertilisation. Againstthis,themajoraimofthebookistoprovideacomprehensive treatment of one well-selected set of key issues of recent ageing research, i. e. health, competence and well-being. In addition, the book's ambition is to identify priorities for future ageing research and to further new avenues for interdisciplinary approaches and social policy applications. The substance of the book is based on an international conference which took place on June 18 and 19, 2004 in Heidelberg, Germany. Framed within the array of health, competence and well-being perspectives in ageing research, the idea of the conf- ence was to provide an integrated presentation of ?ndings generated in the German Centre for Research on Ageing at the University of Heidelberg (Deutsches Zentrum f. ur Alternsforschung, DZFA). The centre's three departments, i. e.

The overturning of Roe v Wade makes the ethical consideration of abortion more important than ever. Appealing to reason rather than religious belief, this book is the most comprehensive case against the choice of abortion yet published. This third edition of The Ethics of Abortion critically evaluates all the major grounds for denying basic rights to fetal human beings, including the views of those who defend not only abortion but also post-birth abortion. It also provides several (non-theological) justifications for the conclusion that all human beings, including those in utero, should be respected as persons. This book also critiques the view that abortion is not wrong even if the human fetus is a person. The Ethics of Abortion examines hard cases for those who are prolife, such as abortion in cases of rape or in order to save the woman's life, as well as hard cases for defenders of abortion, such as sex selection abortion and the rationale for being "personally opposed" but publicly supportive of abortion. It concludes with a discussion of whether artificial wombs might end the abortion debate. Answering the arguments of defenders of abortion, this book provides reasoned justification for the view that all intentional abortions are ethically wrong and that doctors and nurses who object to abortion should not be forced to act against their consciences. Updates and Revisions to the Third Edition Include: Discusses Achas Burin's 2014 essay, "Beyond Pragmatism: Defending the 'Bright Line' of Birth" in chapter 3 Incorporates into chapter 8 David Boonin's cogently argued 2019 book, Beyond Roe: Why Abortion Should be Legal - Even if the Fetus is a Person Expands chapter 9 to examine tragic cases in which prenatal diagnosis determines with certainty that a fetus will die shortly after birth Includes an updated and expanded section in chapter 11 on recent debates about conscience protections Considers in chapter 12 recent arguments that parents have a right to kill if the product of conception is in an artificial womb Updates statistics on numbers of abortions in the United States, including corrections to statistics that were once thought true but are now known as erroneous Updated bibliography

This expansive survey spotlights pervasive issues affecting girls' and women's sexual and reproductive health across the lifecourse. Research from diverse countries around the world analyzes the complex relationships among biological, psychological, sociocultural, and economic issues-particularly in terms of inequities-as they shape women's lives. Major challenges and possibilities for intervention are examined in their national context and with their global implications, including child marriage/motherhood, reproductive care and access, fertility, childbearing, contraception, abortion, HIV/STIs, gender-based violence, sexual pleasure, and menopause. In these forceful dispatches, a consistent human rights perspective emphasizes women's control, autonomy, and agency in all stages of their lives. A sampling of topics covered: Girl child marriage: a persistent global women's health and human rights violation Investigating challenges and resilience among women living with obstetric fistula in Kenya A qualitative exploration of mainstream and social media reflections on abortion A continuum of severity of sexual intimate partner violence among black women in the United States Economic empowerment to improve sexual and reproductive health among women and girls Summarizing an interdisciplinary field on research and practical levels, Global Perspectives on Women's Sexual and Reproductive Health Across the Lifecourse will be an invaluable text for undergraduate and graduate courses in a wide range of fields, including public health, global health, women's studies, sociology, anthropology, gender studies, and human rights.

In species with internal fertilization, sperm competition occurs when the sperm of two or more males simultaneously occupy the reproductive tract of a female and compete to fertilize an egg (Parker, 1970). A large body of empirical research has demonstrated that, as predicted by sperm competition theory, males and females in many species possess anatomical, behavioral, and physiological adaptations that have evolved to deal with the adaptive challenges associated with sperm competition. Moreover, in recent years, evolutionary biologists and psychologists have begun to examine the extent to which sperm competition may have been an important selective pressure during human evolution. Some research has suggested that male humans, like males of many bird, insect, and rodent species, might be able to adjust the number of sperm they inseminate according to the risk of sperm competition. Other research has examined whether such responses might be accompanied by psychological changes that motivate human males to pursue copulations when the risk of sperm competition is high. Furthermore, there is research suggesting that aspects of human penile anatomy might function to enhance success in sperm competition. Much of this work has been controversial; some of the findings have been disputed and others have been greeted with skepticism. However, the idea that some aspects of human psychology and behavior might best be understood as adaptations to sperm competition remains intriguing and, in certain cases, very persuasive.
