Plasma levels of oxidative status assessment
TAOS, OXIDATIVE STRESS
Oxidative stress assessment of participants was performed at baseline, 3 and months follow-up. Serum samples were obtained by centrifugation (1500 × g, 10 min) of the collected blood samples and then kept at -80 °C until the GSH, MDA, TAOS, and TOS parameters were analyzed. Then, they were transferred to the University of Albanian for analyses. Serum concentrations of glutathione (GSH), and malondialdehyde (MDA) were measured by employing a Sciex API 3000 triple quadrupole mass spectrometer as described previously [
