Quinoline-quinoline schiff-base as an effective chromogenic, fluorogenic, and smartphone assisted RGB detection of Pb ion in near aqueous medium.

A novel multimode colorimetric and fluorescent chemosensor was developed using an 8-hydroxy quinoline carbaldehyde Schiff base with a quinoline hydrazide probe (E)-2-((2-(quinolin-2-yl)hydrazineylidene)methyl)quinolin-8-ol (L). NMR (H & C), FTIR, and HR-mass spectral characterization techniques confirmed the probe L structural conformation. As Probe L contacts Pb ions, a color change and turn-off emission can be visually detected in EtOH:HO (1:1, v/v, pH = 7.

Description of a Novel ERBB4 -rearranged Uterine Sarcoma.

High-grade endometrial stromal sarcoma (HGESS) is an uncommon tumor accounting for <1% of all uterine malignancies. Currently this designation is largely reserved for neoplasms harboring YWHAE-NUTM2A/B and ZC3H7B-BCOR translocations. Here, we report a novel CIQTNF1-ERBB4 translocation in a uterine neoplasm arising in a 49-yr-old woman with morphology suggestive of HGESS.
