Journal ArticleDOI
Translocation of Helicobacter pylori CagA into gastric epithelial cells by type IV secretion.
TL;DR: Modulation of host cells by bacterial protein translocation adds a new dimension to the chronic Helicobacter infection with yet unknown consequences.
Journal ArticleDOI
Systematic mutagenesis of the Helicobacter pylori cag pathogenicity island: essential genes for CagA translocation in host cells and induction of interleukin-8.
TL;DR: A point mutation in gene hp0532 is identified, causing a premature translational stop in the corresponding polypeptide chain, providing a putative explanation for the defect in the type IV secretion system of the spontaneous mutant.

TL;DR: The VLT-FLAMES Tarantula Survey (VFTS) as discussed by the authors is an ESO Large Programme that has obtained multi-epoch optical spectroscopy of over 800 massive stars in the 30 Doradus region of the Large Magellanic Cloud (LMC).

TL;DR: In this article, the radial stratification of the so-called clumping factor was analyzed for 19 Galactic O-type supergiants/giants, by combining their own and archival data for Hα, IR, mm and radio fluxes, and using approximate methods, calibrated to more sophisticated models.
