Abstract excerpt

Although the COVID-19 pandemic has now been down-graded, long COVID (LC) presents an ongoing risk of long-term disease for a significant percentage of the population, even after mild or no symptoms upon infection. LC post-viral effects have been associated with oxidative stress (OS), impacting canonical cell function. The aim of this study was to investigate the association of eight OS-related single nucleotide...
