Preferential Solvation by Trifluoroethanol Drives α‐Helical Folding in the Disordered S2 Region of the Escargot Protein

ChemPhysChem, Volume 27, Issue 3, February 2026.
A disordered S2 region of the Escargot protein forms helices which are stabilized by TFE and are correlated with molecular recognition. The N‐terminal domain of the Drosophila melanogaster Escargot transcription factor (Esg) is an intrinsically disordered region (IDR) that complements the DNA‐binding activity of its C‐terminal zinc fingers. Within this

Near‐Infrared Spectroscopy as a Resource for Assessing the Rest and Activation of Pelvic Floor Muscles in Young Adult Women: A Cross‐Sectional Study

Journal of Biophotonics, Volume 19, Issue 2, February 2026.
This study shows that near‐infrared spectroscopy (NIRS) is capable of identifying changes in oxygenation of the pelvic floor muscles during rest and contraction, offering a promising noninvasive alternative for clinical assessment and research in women's health.
