Abnormal Embryogenesis by T.V.N. Persaud Pdf

The study of birth defects has assumed an importance even greater now than in the past because mortality rates attributed to congenital anomalies have declined far less than those for other causes of death, such as infectious and nutritional diseases. It is estimated that as many as 50% of all pregnancies terminate as miscarriages. In the majority of cases this is the result of faulty development. Major congenital malformations are found in at least 2% of all liveborn infants, and 22% of all stillbirths and infant deaths are associated with severe congenital anomalies. Teratological studies of an experimental nature are neither ethical nor justifiable in humans. Numerous investigations have been carried out in laboratory animals and other experimental models in order to improve our understanding of abnormal intrauterine development. In less than two decades the field of experimental teratology has advanced phenomenally. As a result of the wide range of information that is now accumulating, it has become possible to obtain an insight into the causes, mechanisms, and prevention of birth defects. However, considerable work will be needed before these problems can be resolved. The comributions in this volume include some of the more recent and exciting observations on the cellular and molecular aspects of developmental defects. It is not only a documentation of the latest experimental work, but it also indicates new and important areas for future research.

The Embryo by Michael G. Chapman,J. Gedis Grudzinskas,Tim Chard Pdf

A variety of new techniques that promise to revolutionize the clinical management of early pregnancy are fully detailed in this state-of-the-art book. Leading international researchers describe fast-moving topics such as embryo manipulation and the diagnosis of congenital abnormalities. The technology of assisted reproduction has made it possible to study living embryonic material for the first time, which has led to rapid advances in our understanding of the human embryo's early development. For example, study of the embryo in the test tube has pointed to early pregnancy loss as a possible cause of later infertility. Even more important, diagnostic tests using sophisticated techniques of molecular biology can be run on single cells before the embryo is replaced in the uterus. Another area of advance is the diagnosis of congenital abnormalities in the first and second trimesters of pregnancy. Great improvements have been made in the techniques of chorion villus biopsy and ultrasound imaging. A spectrum of simple biochemical tests performed on the mother's blood can greatly improve the detection of Down syndrome and other chromosome defects. Together with other developments in the fields of molecular biology and endocrinology, these new diagnostic techniques are the beginning of a new age in clinical human genetics and embryology.

Scientific Frontiers in Developmental Toxicology and Risk Assessment by National Research Council,Commission on Life Sciences,Board on Environmental Studies and Toxicology,Committee on Developmental Toxicology Pdf

Scientific Frontiers in Developmental Toxicology and Risk Assessment reviews advances made during the last 10-15 years in fields such as developmental biology, molecular biology, and genetics. It describes a novel approach for how these advances might be used in combination with existing methodologies to further the understanding of mechanisms of developmental toxicity, to improve the assessment of chemicals for their ability to cause developmental toxicity, and to improve risk assessment for developmental defects. For example, based on the recent advances, even the smallest, simplest laboratory animals such as the fruit fly, roundworm, and zebrafish might be able to serve as developmental toxicological models for human biological systems. Use of such organisms might allow for rapid and inexpensive testing of large numbers of chemicals for their potential to cause developmental toxicity; presently, there are little or no developmental toxicity data available for the majority of natural and manufactured chemicals in use. This new approach to developmental toxicology and risk assessment will require simultaneous research on several fronts by experts from multiple scientific disciplines, including developmental toxicologists, developmental biologists, geneticists, epidemiologists, and biostatisticians.

Stem Cells and the Future of Regenerative Medicine by Institute of Medicine,Board on Neuroscience and Behavioral Health,National Research Council,Division on Earth and Life Studies,Board on Life Sciences,Committee on the Biological and Biomedical Applications of Stem Cell Research Pdf

Recent scientific breakthroughs, celebrity patient advocates, and conflicting religious beliefs have come together to bring the state of stem cell researchâ€"specifically embryonic stem cell researchâ€"into the political crosshairs. President Bush's watershed policy statement allows federal funding for embryonic stem cell research but only on a limited number of stem cell lines. Millions of Americans could be affected by the continuing political debate among policymakers and the public. Stem Cells and the Future of Regenerative Medicine provides a deeper exploration of the biological, ethical, and funding questions prompted by the therapeutic potential of undifferentiated human cells. In terms accessible to lay readers, the book summarizes what we know about adult and embryonic stem cells and discusses how to go about the transition from mouse studies to research that has therapeutic implications for people. Perhaps most important, Stem Cells and the Future of Regenerative Medicine also provides an overview of the moral and ethical problems that arise from the use of embryonic stem cells. This timely book compares the impact of public and private research funding and discusses approaches to appropriate research oversight. Based on the insights of leading scientists, ethicists, and other authorities, the book offers authoritative recommendations regarding the use of existing stem cell lines versus new lines in research, the important role of the federal government in this field of research, and other fundamental issues.

Pathology of the Human Embryo and Previable Fetus by Dagmar K. Kalousek,Naomi Fitch,Barbara A. Paradice Pdf

This book is designed primarily for anatomic pathologists to facilitate their task of accurately diagnosing embryos and fetuses. A detailed examination of the products of spontaneous and induced abortions is necessary for accurate genetic counseling and for establishing the risk for specific abnormalities or another spontaneous pregnancy loss in the future. The growing interest in the defects of early development reflects the profound change in general life-style. In the past, spontaneous abortions were considered a common, usually sporadic event in a patient's reproductive history. Only reassurance and encour agement were given to the patient and scant attention was paid to the detailed pathology of the abortus. Nowadays, however, as a result of reliable methods of contraception and of the availability of reliable prenatal diagnosis for chromosome abnormalities more frequent in advanced maternal age, significant numbers of parents plan to have pregnan cies later in their reproductive life. Consequently, in a case of spontaneous abortion, the question of "cause" and of "future risk" of recurrence of abortion or an abnormal infant is particularly important. In the era of more elaborate and accurate prenatal diagnostic tests, the pathologist examining products of conception has a primary responsibility to detect, in both spontaneous and induced abortions, any developmental abnormality that would indicate an increased risk of multifactorial, chromosomal, and single gene disorders in a subsequent child.

Congenital Anomalies by Stefania Tudorache Pdf

Nowadays, nobody can imagine practicing obstetrics without using obstetrical ultrasound. Working in the prenatal diagnosis field requires dedication, patience, skills, experience, caution, and empathy. The concept of this book was guided by the desire to provide some help to the ultrasound operators. On a daily basis, they are confronted with the challenging task of ruling out or suspecting/confirming the diagnosis of fetal anomalies, either structural or chromosomal. The chapters of this book contain objective and exhaustive updated reviews of the pertinent literature, so that the reader would have a wide reference basis on each subject. Yet, many authors scan the fetus themselves or are directly involved with managing pregnancies with structural malformations or chromosomal anomalies. They kindly shared their personal experience and lessons learned over the years. This book is beneficial for all the professionals working in the prenatal diagnosis.
