Polonium poisoning case sheds light on infection control practices

A study on Alexander Litvinenko's care reveals that hospital staff involved in routine daily activities, such as handling patient blood and urine samples, were at higher risk of radiation contamination. The findings suggest that more attention should be given to infection control practices during these daily activities.

JCI online early table of contents: Sept. 12, 2011

Researchers have identified the protein BVES as a suppressor of colorectal cancer progression and suggest it could be a therapeutic or preventative target. Modulating BVES expression was found to decrease cancer cell characteristics in human colon cancer cells, providing rational for targeting BVES in individuals with colorectal cancer.
