Effect of high-frequency radiofrequency (6 GHz) electromagnetic radiation on oxidative stress and kidney morphology

This animal experiment exposed rats to 6 GHz RF-EMR from a signal generator for 4 hours/day over 6 weeks and assessed plasma oxidative stress markers and kidney histology. The RF-EMR group showed lower plasma GSH, CAT, SOD, and MDA levels than control and sham groups, while cortisol did not differ. The authors also…

Acute exposure to 27.12 MHz radiofrequency electromagnetic field disrupts blood-brain barrier integrity via eNOS activation and occludin down-regulation.

This animal study examined 27.12 MHz RF-EMF exposure for 30, 180, or 360 minutes in female Wistar rats and assessed markers related to blood-brain barrier integrity. The authors report increased eNOS expression after 30 minutes without oxidative stress or inflammation, alongside decreased occludin expression. Longer…

Exposure to a 900 MHz electromagnetic field induces a response of the honey bee organism on the level of enzyme activity and the expression of stress-related genes.

This animal study exposed one-day-old worker honey bees to 900 MHz RF-EMF at 12, 28, or 61 V/m for 15 minutes, 1 hour, or 3 hours, with an unexposed control group. The authors report changes in hemolymph enzyme activity and in expression of several stress-related genes following exposure. They state the pattern…

Bidirectional Effect of Repeated Exposure to Extremely Low-Frequency Electromagnetic Field (50 Hz) of 1 and 7 mT on Oxidative/Antioxidative Status in Rat's Brain: The Prediction for the Vulnerability to Diseases.

This rat study examined repeated 50 Hz ELF-EMF exposure (1 or 7 mT) and measured oxidative stress and antioxidant defense markers in the prefrontal cortex, including responses to a subsequent open-field stressor. The authors report intensity- and repetition-dependent effects: 1 mT produced weak changes and was…
