Protecting human subjects in research--occasional views along a road less traveled.

Public trust in biomedical research is eroding rapidly because too many investigators participating in human subjects research have failed to take personal responsibility for their actions. In this essay, taken partly from an address to the 66th Annual Research Colloquium of the Massachusetts General Hospital, January 2001, and a presentation to the research community of the Washington University School of Medicine in September, 2000, in St. Louis, Missouri; Greg Koski shares his views about protecting human subjects in biomedical research.
