Discovery of H2 Receptor Antagonists as Colistin Enhancers by Targeting Acid Stress Response
Advanced Science, Volume 13, Issue 26, 8 May 2026.This study identifies YqgB as a key target for restoring colistin susceptibility in mcr‐positive pathogens under acidic conditions by remodeling phospholipid composition and reducing LPS modification. Deep learning‐based screening reveals H2 receptor antagonists as novel colistin adjuvants. Further investigations indicate that ranitidine and famotidine

Ecology and Evolution, Volume 16, Issue 5, May 2026.Here, we de novo assembled the chloroplast genomes of Ranunculus arvensis and Ranunculus laetus, providing comprehensive comparative analysis with 21 congeners. The genomes exhibited conserved quadripartite structures with no major rearrangements, though lineage‐specific variations in atpH position were detected in two species.

Ecology and Evolution, Volume 16, Issue 5, May 2026.This study presents the first complete chloroplast genomes of two medicinally important Stachys species, S. persica and S. germanica. Comparative phylogenomic analyses revealed highly conserved genomes with lineage‐specific variations, identified hypervariable regions as candidate DNA barcodes, and detected signatures of positive selection in the petB ...

Perspectives on Pentaerythritol Tetranitrate (PETN) Decomposition [PDF]
, 2002 This report evaluates the large body of work involving the decomposition of PETN and identifies the major decomposition routes and byproducts. From these studies it becomes apparent that the PETN decomposition mechanisms and the resulting byproducts are primarily determined by the chemical environment.

Cold EI—The Way to Improve GC‐MS and Increase Its Range of Applications
Mass Spectrometry Reviews, Volume 45, Issue 3, Page 548-582, May/June 2026.ABSTRACT Gas chromatography‐mass spectrometry (GC‐MS) with Cold electron ionization (EI) is based on interfacing the GC and MS with a supersonic molecular beam (SMB) along with electron ionization of vibrationally cold sample compounds in the SMB in a contact‐free fly‐through ion source (hence the name Cold EI).

Identification and characterization of a novel Shigella flexneri serotype Yv in China. [PDF]
PLoS ONE, 2013 Shigella flexneri is the major cause of bacterial shigellosis in developing countries. S. flexneri is divided into at least 19 serotypes, the majority of which are modifications of the same basic O-antigen by glucosylation and/or O-acetylation of its ...
