Humans may have two nostrils, but these dont necessarily share the same sense of smell. Elusive scents may be detected by one nostril but not the other. According to a brief communication in Nature (2002;419:802) individual nostrils that are initially non-detectors can be trained through repeated exposure to pick up unusual odours. This implies that although separate nerve supplies connect the nostrils to the brain, there must be some exchange of information going on in the brains olfactory centre.
Myocardial injuries commonly happen when coronary stents are inserted. The extent of the damage depends on local platelet aggregation, inflammation, and increased oxidative stress. Because statins have an effect on these elements, in addition to their lipid lowering effects, cardiologists tested the idea that giving a statin before carrying out stenting procedures might reduce the extent of myocardial damage (Circulation 2002;106:2180-3). Giving statins before the procedure was associated in this small
