They reported that S1P is a missing cofactor that is required for the activity of TRAF2, the key regulator of NF-kappaB, which acts as a master on-off switch in controlling inflammation and cancer… More

The findings, which currently appear on-line at Journal of Alternative and Complementary Medicine, is the first to demonstrate an association between yoga postures, increased GABA levels and decreased anxiety.
