Major bases of concern in biomedical research community are identified, particularly those related to the unexpected year-to-year and institute-to-institute variations in support from NIH. (AL)

Describes the method, present status, and application of positron emission tomography (PET), an analytical imaging technique for "in vivo" measurements of the anatomical distribution and rates of specific biochemical reactions. Measurements and image dynamic biochemistry link basic and clinical neurosciences with clinical findings…

Describes the organization of education, particulary higher education, and medical and scientific research in North Vietnam. Description is based on experiences during a lecture tour as well as available literature. (AL)

Cites several examples of research studies in which medical as well as ethical considerations affected the treatments prescribed. The ethical versus the statistical aspects of drug testing are also discussed. (CP)

Reviews the pros and cons of using animals or alternatives in scientific research. Such alternatives (as indicated in congressional bill HR 556) include mathematical models, isolated organs, tissue and cell cultures, computer simulations, mechanical models, and "lower" organisms among others. (SK)

Analyzes 46 medical research papers on the effects of innovative versus standard surgical procedures on the health of patients. Results reveal that innovations generally reduce complications. The ethics of experimental surgery are also discussed. (CP)

Federal aids provided for training in biomedical research may be stopped. Scientists are pressing for continuation by persuading the administration and possibly winning legislators' support. (PS)

Discusses unpaid postdoctoral researchers, especially those in biology and medicine, addressing reasons why they work without pay, how they receive funding, efforts to help them, their impacts on the field, and personal concerns. (DC)

Discussed is a projected overabundance of physicians by 1990 and a possible cut in funding in medical schools because of this overabundance. Also discussed is the shortage of clinical investigators who are physicians because salaries for physicians are much higher than for clinical investigators. (DS)

Reports on a variety of topics related to experimental design and analysis in the field of medical education. (CP)

In wake of a number of highly publicized incidents of research fraud at some of the nation's most prestigious medical schools, the Association of American Medical Colleges (AAMC) has developed guidelines for coping with dishonesty in science. Highlights of these guidelines are reviewed. (Author/JN)

Discussed is the movement against the use of dissections in science laboratories. Examples of protests across the United States are included. Compared is the plight of using animals in a biology classroom and the demise of the teaching of evolution in some areas. (KR)
