2 postsDoxorubicin-induced cardiotoxicity under 28 GHz 5G-band electromagnetic radiation in rats: Insights into the mitigative role of vitamin C
This animal study tested whether short-term 28 GHz (5G-band) millimeter-wave exposure modifies doxorubicin-induced cardiotoxicity in male rats and whether vitamin C mitigates effects. Co-exposure to 28 GHz EMR was reported to worsen several indices of DOX-related cardiac injury (including CAT reduction, increased BAX expression, and QT prolongation), while vitamin C provided partial attenuation. The authors emphasize that results are limited to a short-duration preclinical model and that human relevance remains preliminary.
Exposure to 26.5 GHz, 5G modulated and unmodulated signal, does not affect key cellular endpoints of human neuroblastoma cells
This in vitro study examined whether 26.5 GHz millimeter-wave exposure (continuous wave and 5G-modulated) affects key cellular endpoints in human neuroblastoma cells. Cells were exposed for 3 hours at SAR 1.25 W/kg using a reverberation-chamber system, with assessments including cell cycle and DNA damage. The study reports no effects from exposure alone or when combined with the oxidant menadione, while noting that additional studies across varied conditions are needed.
