Every year there are new and exciting developments in assisted human reproduction, but how much do we really know about the underlying causes of infertility? This volume explores recent progress in the understanding of the genetics of spermatogenesis and male infertility. Topics include fundamental advances and current problems in the development and function of the testis, an outline of clinical findings in male infertility and an overview of the role of the Y chromosome in male fertility. Comprehensive critiques of posttranscriptional control during spermatogenesis, mammalian meiotic sterility, and comparative genetics of human spermatogenesis from the perspective of yeast, "Drosophila" and mice provide a global overview of the field.

No single area of medicine promises more acrimonious and intense debate in the coming decades than the implications of new medical technologies on the maternal-fetal relationships. This is the only book to combine comprehensive coverage of the legal and social issues raised as a result of both emerging technologies for fetal intervention and increasing knowledge of fetal development. It examines such issues as the effects of maternal behavior on the fetus's health, hazards in the workplace, teenage pregnancy, and the use of therapeutic and diagnostic techniques. The volume also summarizes the legal/political context of policies regarding the mother's responsibility for the welfare of the fetus and describes the current status of these issues in public law. The work opens with a framework for examining rights and, in chapter 2, gives an in-depth description of knowledge about the impact of maternal actions on fetal development. Attention then turns to current trends in case law, as Chapter 3 traces the growing acceptance of causes of legal action for prenatal injury or death of the fetus. Chapter 4 extends this analysis to look at the changing legal context for defining standards of care for pregnant women. Chapter 5 examines three disparate but critical topics illustrating the pressures women face in the 1990s: workplace hazards, teenage pregnancy, and surrogate motherhood. The final chapter integrates the technological, legal, social, and political dimensions surrounding the maternal-fetal relationship into a context for creating an effective public policy.

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.

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.

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.

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.

Given that millions of women have entered menopause each year since the dawn of time, it's bizarre that it still feels like uncharted territory for the women who are going through it.

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.

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.

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.

In recent decades there has been an explosion in work in the social and physical sciences describing the similarities between human and nonhuman as well as human and non-animal thinking. This work has explicitly decentered the brain as the sole, self-contained space of thought, and it has found thinking to be an activity that operates not only across bodies but also across bodily or cellular membranes, as well as multifaceted organic and inorganic environments. For example, researchers have looked at the replication and spread of slime molds (playfully asking what would happen if they colonized the earth) to suggest that they exhibit 'smart behavior' in the way they move as a potential way of considering the spread of disease across the globe. Other scholars have applied this model of non-human thought to the reach of data mining and global surveillance. In The Biopolitics of Alphabets and Embryos, Ruth Miller argues that these types of phenomena are also useful models for thinking about the growth, reproduction, and spread of political thought and democratic processes. Giving slime, data and unbounded entities their political dues, Miller stresses their thinking power and political significance and thus challenges the anthropocentrism of mainstream democratic theories. Miller emphasizes the non-human as highly organized, systemic and productive of democratic growth and replication. She examines developments such as global surveillance, embryonic stem cell research, and cloning, which have been characterized as threats to the privacy, dignity, and integrity of the rational, maximizing and freedom-loving democratic citizen. By shifting her level of analysis from the politics of self-determining subjects to the realm of material environments and information systems, Miller asks what might happen if these alternative, nonhuman thought processes become the normative thought processes of democratic engagement.

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.

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."

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.
