Changes in the ascorbate-glutathione system during storage of recalcitrant seeds of Acer saccharinum L.

open access: yesActa Societatis Botanicorum Poloniae, 2011
Two seed lots of Acer saccharinum (recalcitrant), with an initial moisture content of 50% and 55%, were stored at +3oC for 6 months. After this time, their viability (measured as germinability) reached 100% and 30%, respectively.

Tamoxifen-like metallocifens target thioredoxin system determining mitochondrial impairment leading to apoptosis in Jurkat cells [PDF]

open access: yes, 2017
Tamoxifen-like metallocifens (TLMs) of the group-8 metals (Fe, Ru, and Os) show strong anti-proliferative activity on cancer cell lines resistant to apoptosis, owing to their unique redox properties. In contrast, the thioredoxin system, which is involved
