<div class=quote>Researchers analyzed blood samples before exercise to get a baseline, then took samples again half an hour, 8 hours, 24 hours and 48 hours after moderate exercise.

They found that:

- 71% of the ME/CFS group (34 of 48) had increased expression of 4 genes dealing with sensory and adrenergic receptors and cytokines for 48 hours after exercise; Those with the largest change in genetic expression also had the largest increase in post-exercise symptoms.

- The other 29% of the ME/CFS group (14 of 48) did not show the above changes but did have a decrease in expression of the adrenergic α-2A receptor; This group had significantly more orthostatic intolerance (dizziness upon standing) than the first group.

- Healthy controls and people with FMS had no post-exercises changes in the genes that were studied.

They [the researchers] say the data show two distinct subgroups of ME/CFS and also differentiate fibromyalgia (FMS) from both ME/CFS and healthy controls.</div>
Seems encouraging to me.
