The effect of altered pH growth conditions on the production, composition, and proteomes of Helicobacter pylori outer membrane vesicles

open access: yesPROTEOMICS, Volume 24, Issue 11, June 2024.
Abstract Gram‐negative bacteria release outer membrane vesicles (OMVs) that contain cargo derived from their parent bacteria. Helicobacter pylori is a Gram‐negative human pathogen that produces urease to increase the pH of the surrounding environment to facilitate colonization of the gastric mucosa.

Structural characterization of the Sel1‐like repeat protein LceB from Legionella pneumophila

open access: yesProtein Science, Volume 33, Issue 3, March 2024.
Abstract Legionella are freshwater Gram‐negative bacteria that in their normal environment infect protozoa. However, this adaptation also allows Legionella to infect human alveolar macrophages and cause pneumonia. Central to Legionella pathogenesis are more than 330 secreted effectors, of which there are nine core effectors that are conserved in all ...

Effect of HIP at 1000–1200 °C on microstructure and properties of extruded Be-Ti composites

open access: yesNuclear Materials and Energy, 2022
Solid titanium beryllide blocks will be used for neutron multiplication in the helium-cooled pebble bed (HCPB) blanket concept of EU DEMO. A combination of hot extrusion of Be-Ti powders and subsequent hot isostatic pressing (HIP) of the obtained Be-Ti ...

Thermo-mechanical testing of Li-ceramic for the helium cooled pebble bed (HCPB) breeding blanket

open access: yes, 2004
The helium cooled pebble bed (HCPB) Test blanket module (TBM) for the DEMO Reactor foresees the utilization of lithiate ceramics as breeder in form of pebble beds. The pebbles are organized in several layers alternatively stacked among couples of cooling
