Colonic Crypts: Safe Haven from Microbial Products

The notion that the colon's deep crypt pockets provide a protected location that shields stem cells from potentially toxic substances is widely accepted. In this issue of Cell, Kaiko et al. reveal how a metabolite abundantly produced by the gut microbiota can inhibit stem cell proliferation but is blocked from doing so by crypt architecture.

A Genomic Safe Haven for Mutant Complementation in Cryptococcus neoformans

Just as Koch's postulates formed the foundation of early infectious disease study, Stanley Falkow's molecular Koch's postulates define best practice in determining whether a specific gene contributes to virulence of a pathogen. Fundamentally, these molecular postulates state that if a gene is involved in virulence, its removal will compromise virulence. Likewise, its reintroduction should resto...

Operation Safe Haven: an evaluation of health surveillance and monitoring in an acute setting.

From May to June 1999, 3,920 ethnic Albanians from Kosovo arrived in Australia as part of Operation Safe Haven. These people were evacuated from refugee camps in the former Yugoslav Republic of Macedonia.
