G protein-coupled receptors (GPCRs) transduce signals from a diverse array of endogenous ligands, including ions, amino acids, nucleotides, lipids, peptides, and large glycoprotein hormones. They are also responsible for our sensing of exogenous stimuli, including photons and odorants. GPCRs regulate almost every aspect of our physiological functions. It is estimated that 40% to 50% of currently used therapeutic drugs target GPCRs directly or indirectly. Because the current drugs target only a small portion of the GPCRs, opportunities for targeting the remaining GPCRs is enormous. This volume reviews the latest developments in this rapidly advancing field.

Zilinskas and Balint and their contributors examine the divisions between minority groups and the scientific community, particularly in the area of medical and genetic research. Minorities have reasons to be skeptical of medical research in general and genetics research in particular. The sad history of the Tuskegee experiment, in which black men with syphilis were left untreated so that the course of the disease could be studied, undermined confidence in the ethics of medical researchers. More recently, publication of "The Bell Curve" reanimated controversy over purported genetic distinctions among the races that could have powerfully negative social implications.
In contrast, as the essays make clear, the Human Genome Project, conducted in accordance with the highest ethical standards, has the potential to make dramatic positive contributions to the health of all human beings. Members of minority communities in particular--who statistically are at high risk of adverse health outcomes in the United States--have much to gain from innovative medical diagnostics and therapies that will result from the study of human genetics. Therefore, if we are to benefit fully from this new knowledge, it is vital that the distrust, skepticism, and misconceptions relating to genetics research be overcome. This is a provocative collection for scholars, students, researchers, and community leaders involved with minority and public health issues.
Ever since Dolly, the Scottish lamb, tottered on wobbly legs into our consciousness-followed swiftly by other animals: first, mice; then pigs that may provide human transplants, and even an ordinary house cat-thoughts have flown to the cloning of human beings. Legislators rushed to propose a ban on a technique that remains highly hypothetical, although some independent researchers have announced their determination to pursue the possibilities. Political scientist and well-known expert on reproductive issues, Andrea L. Bonnicksen examines the political reaction to this new-born science and the efforts to construct cloning policy. She also looks at issues that relate to stem cell research, its even newer sibling, and poses a key question:
How does the response to Dolly guide us as we manage innovative reproductive technologies in the future?
Various legislative endeavors and the efforts by the Food and Drug Administration (FDA) to oversee cloning, as well as policy models related to federal funding, individual state laws, and programs abroad, inform Bonnicksen's identification of four types of cloning policy. She analyzes in depth the roles of diverse interest groups as each struggle to become the dominant voice in the decision-making process. With skill and insight, she clears the mists from a complicated topic, and addresses the legal, political, and ethical arguments that are not likely to disappear from the national conversation or debates any time soon.
Discussions and debates over the medical use of stem cells and cloning have always had a religious component. But there are many different religious voices. This anthology on how religious perspectives can inform the difficult issues of stem cell research and human cloning is essential to the discussion. Contributors reflect the spectrum of Christian responses, from liberal Protestant to evangelical to Roman Catholic. The noted moral philosopher, Laurie Zoloth, offers a Jewish approach to cloning, and Sondra Wheeler contributes her perspective on both Jewish and Christian understandings of embryonic stem cell research.
In addition to the discussions found here, God and the Embryo includes a series of official statements on stem cell research and cloning from religious bodies, including the Roman Catholic Church, the Orthodox Church in America, the United Methodist Church, the Southern Baptist Convention, the United Church of Christ, the Presbyterian Church (USA), and the Union of Orthodox Jewish Congregations of America and the Rabbinical Council of America. "Human Cloning and Human Dignity: An Ethical Inquiry," from the statement of the President's Council on Bioethics, concludes the book.
The debates and the discussions will continue, but for anyone interested in the nuances of religious perspectives that make their important contributions to these ethically challenging and important dialectics, God and the Embryo is an invaluable resource.
Genome Visualization by Classic Methods in Light Microscopy begins with an introduction to DNA and RNA, followed by general visualization principles. The subsequent chapters describe: how to prepare tissues for staining; the principles, chemical formulas, and procedures for nuclear dye, fluorescent dye, and histochemical methods; directions to observe the products of the stained reactions; and more. Each protocol is presented as easy-to-follow directions and the author includes cautionary notes and points to consider. The final section provides color photographs of various tissues in which the staining method, fixative, and observations are noted.
A theoretical and practical book, Genome Visualization by Classic Methods in Light Microscopy allows you to understand which technique is most useful for your particular problem. Laboratory protocols are provided for you to follow, chemical structures and principles are provided for you to understand the technique, and the book is organized so you can find the necessary information when needed. This is the essential guide to understanding and executing visualization techniques for nucleic acids.
