Biomarkers in volunteers exposed to mobile phone radiation.

View Original AbstractNo blood-brain barrier effects found in regular cell phone users, but study couldn't test truly unexposed individuals.
Plain English Summary
Swedish researchers tested whether cell phone radiation affects the blood-brain barrier (the brain's protective shield) by measuring specific proteins in blood samples from 24 volunteers before and after exposure to phone-like signals. The study found no significant differences in these barrier-protecting proteins between real exposure and fake exposure sessions. However, the researchers noted that all participants were regular cell phone users, which may have influenced the results.
Study Details
For some time it has been investigated whether low-intensity non-thermal microwave radiation from mobile phones adversely affects the mammalian blood–brain barrier (BBB). All such studies except one have been either in vitro or experimental animal studies. The one carried out on humans showed a statistically significant increase in serum transthyretin (TTR) 60 min after finishing of a 30-min microwave exposure session. The aim of the present study was to follow up on the finding of the previous one using a better study design

Over time, statistically significant variations were found for two of the three biomarkers (TTR; β-t...
In conclusion this study failed to show any acute clinically or statistically significant effect of short term microwave exposure on the serum levels of S100β, TTR and β-trace protein with a follow up limited to two hours. The study was hampered by the fact that all study persons were regular wireless phone users and thus not naïve as to microwave exposure.
