Abstract Background The purpose of this study was to determine an appropriate cutoff value for the resection margin according initial T classification. Methods medical records 151 patients treated by surgery tongue cancer were retrospectively reviewed identify significant perioperative parameters and associated with disease‐specific survival (DSS) recurrence‐free (RFS). Results posterior significantly correlated local recurrence ( P = .020 .016, respectively), whereas deep overall .047)....
Fermented soybean paste (doenjang, FSP) is a traditionally fermented Korean food produced by fermentation with various microorganisms that known to exhibit beneficial bioactivities. To investigate the changes in nonvolatile metabolites of FSP during fermentation, samples six times were analyzed using an 1H nuclear magnetic resonance spectroscopy (NMR)-based metabolomics technique. This revealed clear separation 50% methanol extracts different principal component plots combining PC1 and PC2,...
