Each point could correspond to different individuals. Least square linear 4-HydroxytamoxifenMedChemExpress 4-Hydroxytamoxifen regression with 95 confidence intervals is shownWhen the four groups of patients were constituted considering their medical history, we observed that: (1) the M-wave was found to be significantly reduced only when both infection and emotional stressors were combined; (2) TBARS levels and CD26 expression were markedly altered in patients who had a severe infection, regardless of the presence of a severe emotional stress; (3) the LHS score was markedly low in patients who had a severe infection regardless of the presence of a severe emotional stress, while the score of the pain component of SF-36 was high only when both infection and emotional stressors were combined. Figure 3 collects these data. These results support the importance of infectious stressors in the behavior of the variables we monitored.Discussion In ME/CFS patients, we found that (1) the changes in the M-wave amplitude post-exercise, the alterations of the redox status induced by muscle exercise, and theCD26-expression level are correlated; (2) the LHS score was correlated to the alterations of the redox status induced by exercise and CD26-expression; (3) the pain component of MOS SF-36 was correlated to the CD26expression level. These variables were mainly altered in patients with a history of infectious disease. The oxidative stress refers to an imbalance in the pro- and anti-oxidant status in favour of the former. In healthy subjects, this situation is common in skeletalFenouillet et al.

Data are represented by box plots with 5th and 95th percentiles. Asterisks indicate that values significantly differ from those measured in groups of patients with horizontal bar on top (*p < 0.05; **p < 0.01; ***p < 0.001)muscle following exercise because the muscle anti-oxidant defences are weak [9, 36]. In ME/CFS patients, the present work and others reported increased levels of blood markers of oxidative stress (here, TBARS) and a decreased antioxidant defense (here, RAA), a situation that promotes an oxidative stress, and eventually affects the muscle membrane excitability [10?6]. The correlation found here between the level of oxidative stress and the M-wave alteration is consistent with these.
