For calculation of the SAR, the same method was applied as in previous experiments (see reference article). The SAR value was obtained from FDTD calculations of the EMF distribution in a microtiter suspension well. The dielectric parameters were based on the composition of a mammaliancell also assumed for cells growing on coverslips.

At both 35 and 37°C, higher amounts of Hsp-70 were found in the exposedcells as compared with the sham-exposedcells. The effects can be considered to be athermal. In the heat control experiments the cells had to be heated up to 3-5°C higher, or for much longer time, to get the same maximum responses as were induced by the microwaveirradiation. There was no significant response in the case of Hsp-27.
