Animal biotechnology represents one subset of tools among a larger set of technologies for potential use to meet increasing world demands for food. Assisted reproductive technologies (ART) such as artificial insemination and embryo transfer continue to make positive contributions in food animal production. The US Food and Drug Administration (FDA) performed a comprehensive risk assessment to identify potential food consumption or animal health risks associated with animal cloning, an emerging ART. At that time, FDA concluded that animal cloning posed no unique risks either to animal health or to food consumption, and food from animal clones and their sexually reproduced offspring required no additional federal regulation beyond that applicable to conventionally bred animals of the species examined. At this time, no new information has arisen that would necessitate a change in FDA's conclusions on food from animal clones or their sexually reproduced offspring. Use of recombinant DNA technologies to produce genetically engineered (GE) animals represents another emerging technology with potential to impact food animal production. In its regulation of GE animals, FDA follows a cumulative, risk-based approach to address scientific questions related to the GE animals. FDA evaluates data and information on the safety, effectiveness and stability of the GE event. FDA carries out its review at several levels (e.g. molecular biology, animal safety, food safety, environmental safety and claim validation). GE animal sponsors provide data to address risk questions for each level. This manuscript discusses FDA's role in evaluation of animal cloning and GE animals., (© 2012 Blackwell Verlag GmbH.)

HIV infection is a chronic illness that affects individuals of all ages. The pulmonary system is the most common body system affected by the disease. Management of these complications has improved over the years and has resulted in a decline in mortality. Critical care nurses should understand the complications that develop and be knowledgeable about the management to improve the patient's clinical outcomes. Assessment for complications must begin once an individual is diagnosed as being infected with HIV and continue throughout the course of the disease. Prevention is the key to limiting respiratory complications and thus improving survival rates.

Firearm violence has reached an alarming level. The devastation that results from firearms has severe implications for the individual and society. Interventions for patients suffering firearm injuries must begin at the scene and continue through the many phases of illness including emergency care, critical care, intermediate care, rehabilitation, and home care. Nurses are in the prime position to coordinate the many phases of care, with the outcome being to incorporate the victim back into society. Prevention is the key to reducing firearm violence through awareness, education, and legislation.

Computers play an increasingly important role in radiology education and research. We surveyed all U.S. residency programs to assess computer availability, education, and use by residents. Out of 210 questionnaires sent, 132 were returned (63% response). Areas of inquiry included computer equipment and software as well as resident use of facilities. Opinions were also solicited concerning the importance of computer literacy and education. Sixty-nine percent of the respondents have computer facilities (61% within the department). Predominant uses include scientific papers, slides/audiovisual presentations and resume preparation. Popular software includes word processing, spreadsheets, databases and graphics. Of those training programs with computers, 85% provided computer education, and most (70%) felt computer training was very important. Forty-seven percent expected their residents to have at least passing acquaintance with computers. However, in 60% of programs with computers, the computers are used by less than half the residents. Of those programs without a computer, 61% provided no computer training, and only 44% felt computer education was very important. A sizable minority of radiology residency programs are still without computer facilities. Those programs that have computers tend to place a greater emphasis on computer education and literacy for radiology residents. However, even in programs that have computers, it seems they are often underutilized by residents.
