  "main_findings": "In pregnant mice, exposure to 900 MHz mobile radiation (2 W; power density 0.045 μW/cm2) for 8 hours/day for 10 days was reported to increase blood MDA and 8-OHdG and decrease total antioxidant capacity compared with controls.

  "summary": "This animal study examined whether 900 MHz mobile radiation induces oxidative stress in pregnant mice and whether vitamin C modifies these effects. The authors report increased blood MDA and 8-OHdG and decreased total antioxidant capacity after RF exposure versus controls. Vitamin C co-exposure was reported to inhibit the significant increases in MDA and 8-OHdG.",
  "key_points": [
    "Twenty-one pregnant mice were assigned to control, RF-exposed, or RF-exposed plus vitamin C groups.",
    "Exposure was 900 MHz mobile radiation at 2 W and 0.045 μW/cm2 for 8 hours/day over 10 days.",
    "Blood oxidative stress markers (MDA, 8-OHdG) increased and total antioxidant capacity decreased in exposed groups.",
    "Vitamin C (200 mg/kg) was reported to inhibit the significant increases in MDA and 8-OHdG.",
    "The abstract does not report SAR or detailed dosimetry beyond power and power density.",
    "The outcomes are biomarker-based and do not include pregnancy or offspring endpoints in the abstract."
