Sodium acetate (reagent grade), acetic acid (glacial, 99.99 + %), and l-ascorbic acid (reagent grade) were acquired from Sigma (St . Louis MO, USA).

OA grade (OARS I, acquired from the histological analysis, is provided for the final time point only and presented versus the contralateral limb score underneath.
In the 5 tumors with ISUP nucleolar (nuclear) grade 3 nuclei, which were still recognizable as SDH-deficient renal carcinomas, in addition to prominent nucleoli, the neoplastic cells in the higher-grade areas acquired darker and coarser chromatin and more dense eosinophilic (rather than flocculent) cytoplasm.
