Air pollution raises risk for dangerous arrhythmias among people with ICDs

Researchers from the Harvard School of Public Health and colleagues from Boston area medical institutions have linked short term high pollution concentrations with an increased incidence of irregular and very dangerous heart arrhythmias among a group of cardiac patients from the greater Boston area who had implanted cardioverter defibrillators (ICD). The findings appear in the June 1, 2005 issue of Environmental Health Perspectives. more

Drug to block mother-to-child HIV transmission induces resistance more often than previously thought

The incidence of drug resistance associated with single-dose nevirapine, a drug used to prevent mother-to-child transmission of HIV-1, may be substantially higher than previously thought and of particular risk for those infected with HIV-1 subtype C, according to three new studies published in the July 1 issue of The Journal of Infectious Diseases, now available online. more  

Brain networks change according to cognitive task

Using a newly released method to analyze functional magnetic resonance imaging (fMRI), Northwestern University researchers have demonstrated that the interconnections between different parts of the brain are dynamic and not static. This and other findings answer longstanding debates about how brain networks operate to solve different cognitive tasks. They are presented in the current (June 1) issue of the Journal of Neuroscience. more
