Transgenics refers to those specific genetic engineering processes that remove genetic material from one species of plant or animal and add it to a different species.
The site presents many excellent articles that deal with varied bioethical issues. It contains a detailed description of the philosophy and components of critical thinking.
Decisions involving bioethical issues are made every day in diverse situations such as the relationship between patients and their physicians, the treatment of human subjects in biomedical experimentation, the allocation of scarce medical resources, the complex questions that surround the beginning and the end of a human life and the conduct of clinical medicine and life sciences research.
Ethicists serve as advisers to hospitals and other health care institutions. They also have served as advisers to federal and state legislatures in the writing of laws concerning the decision to end life support, the use of genetic testing, physician-assisted suicide and other matters.
Bioethics even has become part of the landscape in the commercial world of science.
An increasing number of firms involved in biotechnology regularly consult with biomedical ethicists about business and research practices. In the United States and Canada, more than 25 universities offer degrees in medical ethics. In many instances, the subject also is part of the curriculum in the education of physicians and other health care professionals.
Many medical schools include ethics courses that examine topics such as theories of moral decision-making and the responsible conduct of medical research. A Diversity of Definitions Depending on the creator of the definition, bioethics is defined as: After the s, the advent of new medical and reproductive technologies further complicated the moral and societal issues of biomedical research and medical practice.
To better evaluate medical cases and make decisions, medical ethicists have tried to establish specific ethical frameworks and procedures.
One system, developed in the late s by American philosopher Tom Beauchamp and American theologian James Childress, is known as principlism, or the Four Principles Approach.
In this system, ethical decisions pertaining to biomedicine are made by weighing the importance of four separate elements: Beauchamp and Childress also were members of the member committee that developed the important historical document Ethical Principles and Guidelines for the Protection of Human Subjects for the Department of Health and Human Services.
Issued inthe document, better known as The Belmont Report named for the conference center where it was draftedestablished the principles of respect, beneficence and justice as the cornerstones for regulations involving human participants in medical research.
While some medical ethicists follow principlism, others employ a system known as casuistry — a case-based approach. When faced with a complex bioethical case, casuists attempt to envision a similar yet clearer case in which virtually anyone could agree on a solution.
By weighing solutions to the hypothetical case, casuists work their way toward a solution to the real case at hand. Casuistry and principlism are just two of many bioethical frameworks. Each approach has its proponents, and volleys of disagreement and debate fly frequently among the various schools of thought.
Yet, each approach represents an attempt to deal with touchy, conflicting issues that commonly arise in the complex and contentious arena of medicine. Advances in medical science have created new and difficult moral choices for individuals, their families and the health professionals who work with them.
As scientists and physicians are faced with new and exciting options for saving lives, transplanting organs and furthering research, they also must wrestle with new and troubling choices, such as who should receive scarce and vital treatment and how we determine when life ends.
Bioethical dilemmas, once rare, now are commonplace, in part because new medical technologies have outpaced our ability to understand their implications. Traditionally, bioethicists have dealt with difficult medical decisions, but their role has expanded with the explosion of knowledge in the fields of genetics and biotechnology.
Ethical decisions are required for issues as diverse as cloning, the use of fetal tissues and the genetic engineering of crops. The recent growth in the fields of biomedical, bioengineering and biotechnology research has created an unprecedented need for our society to confront the new and challenging ethical implications that arise.
Bioethics consists of identifying emerging moral issues related to human heath and biological systems and analyzing them according to the principles determined by the value system of the community.
Bioethical Decision-Making Decision-making in bioethics occurs when an individual or group of individuals confronts a bioethical dilemma that requires a choice be made between two or more seemingly conflicting outcomes. Often, there are both positive and negative consequences to each of these possible outcomes.
In trying to reach decisions, bioethicists consider the following paradigms: Community In this paradigm, the needs and interests of the individual are weighed against the needs and interests of the community.In the medicine field, gene therapy (also called human gene transfer) is the therapeutic delivery of nucleic acid into a patient's cells as a drug to treat disease.
The first attempt at modifying human DNA was performed in by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May For teachers.

In September the Council began an inquiry into ethical issues raised by genome editing as an emerging biomedical technology that could influence inherited characteristics in human beings.
Updated November Introduction. Genetic engineering, or genetic modification, uses a variety of tools and techniques from biotechnology and bioengineering to modify an organism’s genetic makeup. The Nuffield Council on Bioethics is one of the most forward-thinking ethics boards in the world.
Six years ago, the council approved a controversial fertility treatment requiring three genetic. The genetic engineering of animals has increased significantly in recent years, and the use of this technology brings with it ethical issues, some of which relate to animal welfare — defined by the World Organisation for Animal Health as “the state of the animal how an animal is coping with.
