Fetal Cells in Maternal Blood


Book Description

Several lines of evidence indicate that foetal cells - lymphocytes, nucleated red cells, trophoblasts - exist in maternal blood during pregnancy. The potential thus exists for recovering foetal cells from maternal blood and then analysing these cells for foetal genetic abnormalities. This volume explores the biology and maternal foetal transfer of the three cell types during pregnancy, the use of flow cytometry and other techniques to enrich the yield of these cells from maternal blood, the application of diagnostic techniques for identifying cytogenetic and other genetic abnormalities, and public health and other issues involved in the implementation of such testing.







Mammography and Beyond


Book Description

X-ray mammography screening is the current mainstay for early breast cancer detection. It has been proven to detect breast cancer at an earlier stage and to reduce the number of women dying from the disease. However, it has a number of limitations. These current limitations in early breast cancer detection technology are driving a surge of new technological developments, from modifications of x-ray mammography such as computer programs that can indicate suspicious areas, to newer methods of detection such as magnetic resonance imaging (MRI) or biochemical tests on breast fluids. To explore the merits and drawbacks of these new breast cancer detection techniques, the Institute of Medicine of the National Academy of Sciences convened a committee of experts. During its year of operation, the committee examined the peer-reviewed literature, consulted with other experts in the field, and held two public workshops. In addition to identifying promising new technologies for early detection, the committee explored potential barriers that might prevent the development of new detection methods and their common usage. Such barriers could include lack of funding from agencies that support research and lack of investment in the commercial sector; complicated, inconsistent, or unpredictable federal regulations; inadequate insurance reimbursement; and limited access to or unacceptability of breast cancer detection technology for women and their doctors. Based on the findings of their study, the committee prepared a report entitled Mammography and Beyond: Developing Technology for Early Detection of Breast Cancer, which was published in the spring of 2001. This is a non-technical summary of that report.




Building Genetic Medicine


Book Description

A comparative study of genetic testing for breast and ovarian cancer in the United States and Britain that shows the importance of national context in the development and use of science and technology even in an era of globalization. In Building Genetic Medicine, Shobita Parthasarathy shows how, even in an era of globalization, national context is playing an important role in the development and use of genetic technologies. Focusing on the development and deployment of genetic testing for breast and ovarian cancer (known as BRCA testing) in the United States and Britain, Parthasarathy develops a comparative analysis framework in order to investigate how national “toolkits” shape both regulations and the architectures of technologies and uses this framework to assess the implications of new genetic technologies. Parthasarathy argues that differences in the American and British approaches to health care and commercialization of research led to the establishment of different BRCA services in the two countries. In Britain, the technology was available through the National Health Service as an integrated program of counseling and laboratory analysis, and was viewed as a potentially cost-effective form of preventive care. In the United States, although BRCA testing was initially offered by a number of providers, one company eventually became the sole provider of a test available to consumers on demand. Parthasarathy draws lessons for the future of genetic medicine from these cross-national differences, and discusses the ways in which comparative case studies can inform policy-making efforts in science and technology.







Mobilizing Mutations


Book Description

With every passing year, more and more people learn that they or their young or unborn child carries a genetic mutation. But what does this mean for the way we understand a person? Today, genetic mutations are being used to diagnose novel conditions like the XYY, Fragile X, NGLY1 mutation, and 22q11.2 Deletion syndromes, carving out rich new categories of human disease and difference. Daniel Navon calls this form of categorization “genomic designation,” and in Mobilizing Mutations he shows how mutations, and the social factors that surround them, are reshaping human classification. Drawing on a wealth of fieldwork and historical material, Navon presents a sociological account of the ways genetic mutations have been mobilized and transformed in the sixty years since it became possible to see abnormal human genomes, providing a new vista onto the myriad ways contemporary genetic testing can transform people’s lives. Taking us inside these shifting worlds of research and advocacy over the last half century, Navon reveals the ways in which knowledge about genetic mutations can redefine what it means to be ill, different, and ultimately, human.




Genetics and the Behavior of Domestic Animals


Book Description

Behavior is shaped by both genetics and experience--nature and nurture. This book synthesizes research from behavioral genetics and animal and veterinary science, bridging the gap between these fields. The objective is to show that principles of behavioral genetics have practical applications to agricultural and companion animals. The continuing domestication of animals is a complex process whose myriad impacts on animal behavior are commonly under-appreciated. Genetic factors play a significant role in both species-specific behaviors and behavioral differences exhibited by individuals in the same species. Leading authorities explore the impact of increased intensities of selection on domestic animal behavior. Rodents, cattle, pigs, sheep, horses, herding and guard dogs, and poultry are all included in these discussions of genetics and behavior, making this book useful to veterinarians, livestock producers, laboratory animal researchers and technicians, animal trainers and breeders, and any researcher interested in animal behavior. Includes four new chapters on dog and fox behavior, pig behavior, the effects of domestication and horse behavior Synthesizes research from behavioral genetics, animal science, and veterinary literature Broaches fields of behavior genetics and behavioral research Includes practical applications of principles discovered by behavioral genetics researchers Covers many species ranging from pigs, dogs, foxes, rodents, cattle, horses, and cats




Myriad Genetics


Book Description

From the late 1980s, a storm surrounding the wisdom, ethics and economics of human gene patents has been brewing. The various winds of concern in this storm touched on the impact of gene patents on basic and clinical research, on health care delivery, and on the ability of public health care systems to provide equal access when faced with costly patented genetic diagnostic tests. Myriad Genetics, Inc. along with its subsidiary, Myriad Genetic Laboratories, Inc., a small Utah-based biotechnology company, found itself unwittingly in the eye of this storm after a series of decisions it made regarding the commercialization of a hereditary breast cancer diagnostic test. This case study examine the background to Myriad's decisions, the context in which these decisions were made and the policy, research and business response to them.




Star Trek: Myriad Universes #2: Echoes and Refractions


Book Description

It's been said that for any event, there are an infinite number of possible outcomes. Our choices determine which outcome will follow, and therefore all possibilities that could happen do happen across countless alternate realities. In these divergent realms, known history is bent, like white light through a prism -- broken into a boundless spectrum of what-might-have-beens. But in those myriad universes, what might have been...is what actually happened. THE CHIMES AT MIDNIGHT: In a continuum where Spock died during childhood, an Andorian named Thelin became Captain Kirk's stalwart friend and first officer. But at the moment of Khan's final defeat, history takes an even stranger turn, and the emerging potential of Project Genesis is revealed as the galaxy's greatest hope...and its most ominous threat. A GUTTED WORLD: Terrorist Kira Nerys -- from a Bajor that was never liberated -- may hold the key to winning a war that has engulfed half the galaxy.
