Thelwall – 16 November 2013 – Oxidative stress (OS) plays a central role in the progression of liver disease and in damage to liver by toxic xenobiotics. We have developed methods for noninvasive assessment of hepatic OS defenses by measuring flux through the glutathione (GSH) synthesis pathway. 13C‐labeled GSH is endogenously produced and detected by in vivo magnetic resonance after administration of [2‐13C]‐glycine.
