This laboratory study examined how electromagnetic field (EMF) treatment affects biochemical and antioxidant-related components in tea samples, including flavonoid markers measured by HPLC. The abstract reports that 30-minute exposures generally increased several flavonoids compared with 60-minute exposures, with the…

This animal experiment assessed whether long-duration 4G-LTE mobile phone electromagnetic field exposure affects spermatogenesis in male rats. After 1 month, the highest exposure condition (3 cm distance, 18 h/day) had reduced spermatid, spermatogonia, total germ cell, and Leydig cell counts compared with sham and…

This in vitro study examined whether extremely low-frequency electromagnetic fields (ELF-EMF) affect growth of Staphylococcus aureus and Escherichia coli O157:H7. Bacterial cultures were exposed to sinusoidal homogeneous ELF-EMF at 2 or 4 mT, with frequencies of 20, 40, or 50 Hz, for 1–6 hours, and CFU were compared…

This experimental study exposed adult male Wistar rats to 900 MHz GSM-band cell phone-related waves for 2 or 3 weeks and assessed sperm parameters and total antioxidant capacity. All exposure groups showed significantly reduced sperm viability, motility, and total antioxidant capacity compared with controls.…

This occupational exposure assessment monitored surgeons during 11 surgeries using monopolar electro surgery units and measured electric and magnetic field strengths during cutting and coagulating modes. Electric fields near the cable at 10 cm were reported in the hundreds of V/m, while magnetic fields were
Experimental study of relationship between biological hazards of low-dose radiofrequency exposure and energy flow density in Spirostomum ambiguum infusoria exposed at a mobile connection frequency (1 GHz).

This experimental study exposed Spirostomum ambiguum infusoria to 1 GHz radiofrequency fields at 5 and 50 μW/cm² and reports reduced motor activity. The effect was described as threshold-like, appearing after a certain exposure duration and not increasing with longer exposure. The authors report different 'safe'…

Jan 1, 2011
This animal study examined whether an extremely low frequency magnetic field (7 mT, 40 Hz) used in magnetotherapy alters oxidative balance in rat brain after 10 days of exposure. The 30 min/day exposure condition was associated with increased lipid peroxidation, while the 60 min/day condition was associated with…

This animal study exposed Sprague-Dawley rats to a 40 Hz, 7 mT time-variable magnetic field and measured ECG heart rate and plasma antioxidant capacity before and after exposure, including after 14 days. The authors report a significant decrease in heart rate after 14 days. Antioxidant defence findings were mixed,…

Jan 1, 2008
This in vitro study exposed primary cultured rat neurons to 1.8 GHz RF-EMF at an average SAR of 2 W/kg and assessed gene expression changes. The authors report multiple differentially expressed genes after 24 h intermittent exposure and confirm exposure-dependent changes in Egr-1, Mbp, and Plp by semi-quantitative…
