Immune Evasion of Helicobacter pylori and Extra‐Gastric Cancer Risk

open access: yesJournal of Gastroenterology and Hepatology, EarlyView.
ABSTRACT Helicobacter pylori (H. pylori) is a group 1 gastric carcinogen that plays a significant role in extra‐gastric digestive system cancers. H. pylori disrupts host cell homeostasis through expression of virulence factors leading to immune evasion as well as persistent gastric mucosal colonization. H. pylori infection has been shown to play a role

Too close for comfort: Self‐crowding transforms protein structure and stability beyond volume exclusion

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Proteins operate in crowded physiological environments, yet their conformational and oligomeric states are largely inferred from experiments performed under dilute buffer conditions. Here, we show that for lysozyme (LYS) and bovine serum albumin (BSA), self‐crowding at physiologically relevant concentrations alters protein structure and ...

Density-functional studies of tungsten trioxide, tungsten bronzes, and related systems

open access: yes, 2005
Tungsten trioxide adopts a variety of structures which can be intercalated with charged species to alter the electronic properties, thus forming `tungsten bronzes'.

Quantifying Carboxylate Burial in Synthetic Hydrophobic Pockets in Water

open access: yesChemistryEurope, Volume 4, Issue 5, May 2026.
How “buried” is a buried ion? Double mutant cycles quantify the cost of placing a carboxylate within a deep aromatic calix[4]pyrrole pocket in water. The penalty is only +1.3 to +3.0 kcal·mol−1 because water penetrates through cracks and the portal, creating a wet, high‐dielectric microenvironment.

On The Theory of Time dilation in Chemical Kinetics

open access: yes, 2017
The rates of chemical reactions are not absolute but their magnitude depends upon the relative speeds of the moving observers. This has been proved by unifying theories of chemical kinetics, which are transition state theory, collision theory, RRKM and ...
