Helicobacter pylori's road to colonization

In this issue of the Biomedical Journal we learn about the virulence factors that have made Helicobacter pylori such a successful pathogen. We also highlight some in vitro findings that may shed light on epithelial–mesenchymal transition that occurs during renal fibrosis. This issue also includes the findings of clinical trials testing the effectiveness of drugs to limit nausea in chemotherapy patients and the symptoms of alcohol withdrawal syndrome.
