Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Crystal structure of 2-phenylethanaminium 3-carboxyprop-2-enoate
The title molecular salt, C8H12N+·C4H3O4−, crystallized with two independent cations and anions in the asymmetric unit. The ethanaminium side chains of the cations exhibit anti conformations [C—C—C—N torsion angles = 176.5 (3) and −179.4 (3)°].

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

2-Amino-4-methylpyridinium 2-hydroxybenzoate
The title molecular salt, C6H9N2+·C7H5O3−, contains two ion pairs in the asymmetric unit. Both anions feature an intramolecular O—H...O hydrogen bond, which closes an S(6) ring. In the crystal, N—H...O hydogen bonds link the components into [010] chains,

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

2-Amino-3-methylpyridinium hydrogen phthalate
In the title molecular salt, C6H9N2+·C8H5O4−, the cation is protonated at the pyridine N atom and the anion is deprotonated at the hydroxy O atom. The anion features an intramolecular O—H...O hydrogen bond with the H atom located almost in the middle of ...

Understanding the microsolvation of salts in molecular clusters [PDF]
The solvation of salts in water and salt–water interactions are important for understanding a large variety of chemical, biological, and atmospheric processes. In this perspective, we summarize our recent studies on the theoretical modeling of salt–water clusters.

Combining osimertinib with the STING agonist ADU‐S100 activates innate and adaptive immunity to overcome the non‐inflamed microenvironment of Egfr‐mutant lung cancer. This combination increases NK and CD8+ T‐cell infiltration, associated with activation of the STING‐IRF3 pathway and local immunogenic cell death.
