Quadruple therapies show a higher eradication rate compared to standard triple therapy for Helicobacter pylori infection within the LEGACy consortium. A multicenter observational study in European and Latin American countries. [PDF]

open access: yesUnited European Gastroenterol J
Abstract Introduction Gastric cancer (GC) is one of the most lethal malignancies worldwide. Helicobacter pylori is the primary cause of GC; therefore, its eradication reduces the risk of developing this neoplasia. There is extensive evidence regarding quadruple therapy with relevance to the European population.

A whole-cell hypersensitive biosensor for beta-lactams based on the AmpR-AmpC regulatory circuit from the Antarctic Pseudomonas sp. IB20. [PDF]

open access: yesMicrob Biotechnol
In this study, we developed a biosensor based on the AmpC beta‐lactamase regulation system from Pseudomonas sp. IB20 to detect antibiotic residues, with a focus on beta‐lactams. We replaced the ampC coding sequence with a fluorescent protein, creating a whole‐cell biosensor in Escherichia coli, which exhibited dose‐dependent detection of penicillins ...

What controls the remobilization and deformation of surficial sediment by seismic shaking? Linking lacustrine slope stratigraphy to great earthquakes in South–Central Chile

open access: yesSedimentology, Volume 68, Issue 6, Page 2365-2396, October 2021., 2021
Abstract Remobilization and deformation of surficial subaqueous slope sediments create turbidites and soft sediment deformation structures, which are common features in many depositional records. Palaeoseismic studies have used seismically‐induced turbidites and soft sediment deformation structures preserved in sedimentary sequences to reconstruct ...
