As of September 1996, the US Food and Drug Administration will regulate PET radiotracers as drugs. The PET community argues that such ‘heavy-handed’ regulation will halt PET's progress as a clinically effective diagnostic technique.
By integrating concepts of computer graphics and artificial intelligence, novel ways of representing medical knowledge become possible. They allow unprecedented possibilities ranging from three-dimensional interactive atlases to systems for surgery rehearsal
The finding that the drug clotrimazole has potent inhibitory effects on cell proliferation offers new challenges for therapy and biological investigation (pages 534–540).
The specific targeting of signal transduction components implicated in vascular disease may be accomplished more efficiently with genes than with drugs (pages 541–545).
Pollutant research is moving indoors as scientists uncover new links between indoor exposure and disease. However, measuring the levels of exposure is a difficult task.
The induction of ulcerative colitis in mice with targeted disruptions of a G protein-encoding gene establishes yet another genetic link between G proteins and disease.
What DNA interactive ligands, such as antitumour agents and carcinogens, can do is well known, but exactly how they do it has been a mystery until now.
