AbstractWaterlogged archeological wood (WAW) undergoes lignin oxidation in the presence of air, generating quinones and other conjugated chromophores that cause severe discoloration. As conventional reductants (e.g., Na2S2O4 and NaBH4) struggle to balance between decolorization performance and operational compatibility, a thiourea dioxide (TDO)–amine borane (AB) composite formulation was developed for WAW decolorization. A paper-based solid-phase model with a covalently linked o-quinone motif was constructed for quantitative evaluation. The performances of TDO, dimethylamine borane (DMAB), tert-butylamine borane (TBAB), and their combinations were evaluated on both model and WAW samples. The TDO–AB formulations outperformed single-component treatments in decolorization effect and rate.

Findings may help identify patients who are less likely to respond to neoadjuvant therapy, potentially informing timely consideration of alternative treatment strategies or surgery 68Ga-HER2 PET/CT images before neoadjuvant therapy, at end of second cycle, and before surgery. (A) Baseline scan demonstrated soft-tissue lesion measuring approximately 2.3 × 2.2 cm in upper outer quadrant of left breast, with marked radiotracer uptake and SUVmax of 10.1. (B) At end of second cycle, imaging revealed residual lesion of approximately 2.2 × 1.0 cm in same region, without abnormal radiotracer accumulation. (C) Preoperative imaging demonstrated further reduction in lesion size to approximately 2.0 × 0.6 cm, with no abnormal tracer uptake detected.
