Varying effects of stream restoration on riparian soil carbon persistence and methane emissions in the southern Rocky Mountains, United States

Restoration Ecology, EarlyView.
Abstract Introduction Channel incision can disconnect streams from their floodplains, potentially depleting carbon (C) in riparian soils by stimulating microbial decomposition. Stream restoration may offer an opportunity to replenish soil C pools by saturating riparian soils with water and slowing microbial activity.

Drafting the calmodulation playbook: Emerging structural insights into transient receptor potential channel regulation by calmodulin

The Journal of Physiology, EarlyView.
Abstract figure legend Calmodulin (CaM) is a ubiquitous calcium (Ca2+) sensor that translates intracellular Ca2+ signals into modulation of hundreds of effector proteins including ion channels. CaM is increasingly recognized as a key regulator of the transient receptor potential (TRP) channel family, yet the underlying ‘calmodulation playbook’ is only ...

Histological Helicobacter pylori Density Might Not be Associated With the Severity of Neutrophilic Inflammatory Activity

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Background While the Updated Sydney System classifies Helicobacter pylori density together with inflammatory scores, the clinical relevance of bacterial load remains uncertain. This study aimed to assess the association between histological H. pylori density and the severity of gastric inflammatory activity.

A Dominant Negative Mutant of Helicobacter pyloriVacuolating Toxin (VacA) Inhibits VacA-induced Cell Vacuolation [PDF]

Journal of Biological Chemistry, 1999
Most Helicobacter pylori strains secrete a toxin (VacA) that causes structural and functional alterations in epithelial cells and is thought to play an important role in the pathogenesis of H. pylori-associated gastroduodenal diseases. The amino acid sequence, ultrastructural morphology, and cellular effects of VacA are unrelated to those of any other ...
