Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

EIF5A Couples Translational Control With Transcriptional Reprogramming Through Chromocenter Reorganization During Spermiogenesis

Advanced Science, Volume 13, Issue 9, 13 February 2026.
The translation factor Eukaryotic translation initiation factor 5A (eIF5A) is essential for male fertility in mice. It supports the translation of proteins crucial for heterochromatin organization and acrosome formation. eIF5A deficiency disrupts chromocenter integrity, increases chromatin accessibility, and causes transcriptional dysregulation ...

Development of Suppressed Ion Chromatography for the Online Quantification of Cations in Electrochemical Ammonia Synthesis Research

ChemSusChem, Volume 19, Issue 3, February 2026.
We developed a suppressed ion chromatography method with automated matrix neutralization and matrix elimination for the quantitative determination of ammonium in electrochemical ammonia synthesis research. Online determination of ammonium in 0.2 M sulfuric acid electrolyte revealed Nafion ionomer as a non‐negligible secondary source of ammonium ...
