Alpha-Lipoic Acid Preserves Testicular Integrity Under 2.45 GHz Electromagnetic Radiation by Restoring Redox and Inflammatory Balance
Unknown authors · 2025
EMR exposure caused marked structural damage to seminiferous tubules, increased collagen deposition, expanded tubular and interstitial volumes, raised IL-6 and TNF-α expression, and reduced antioxidant enzyme activities while increasing MDA levels. Alpha-lipoic acid supplementation prevented the structural damage, lowered inflammatory markers, restored AR, ZO-1, and ZO-2 expression, and reversed the oxidative stress parameters.

Effects of 700 and 3500 MHz 5G radiofrequency exposure on developing zebrafish embryos
Torres-Ruiz M et al. · 2024
Researchers exposed zebrafish embryos to unmodulated 700 MHz and 3500 MHz radiofrequency radiation for 1 and 4 hours during the blastula period and assessed outcomes up to 120 hours post fertilization. The exposure did not affect mortality, hatching, or body length, but caused specific organ morphological changes and lasting behavioral alterations in activity, anxiety-like behavior, and habituation. Effects were stronger at 700 MHz, particularly after 4 hours of exposure, and acetylcholinesterase activity was reduced.

Effect of 2850 MHz electromagnetic field radiation on the early growth, antioxidant activity, and secondary metabolite profile of red and green cabbage (Brassica oleracea L
Unknown authors · 2024
Researchers studied the impact of 2850 MHz electromagnetic field radiation on red and green cabbage seedlings, exposing them daily for seven days to homogeneous EMF-r for one, two, or four hours. Exposure caused dose-dependent reductions in root length, shoot length, and biomass in both cultivars compared with controls. Chlorophyll and carotenoid contents decreased significantly in both red and green cabbage. Phenolic, flavonoid, and anthocyanin contents increased with exposure duration in both cultivars. EMF-r produced oxidative stress shown by dose-dependent increases in total antioxidant activity, DPPH activity, H2O2 content, and MDA content, while antioxidant enzyme activities increased significantly.
Exposure to Radiofrequency Induces Synaptic Dysfunction in Cortical Neurons Causing Learning and Memory Alteration in Early Postnatal Mice
Unknown authors · 2024
The study investigated the effects of 1850 MHz RF-EMF exposure at a specific absorption rate of 4.0 W/kg on cortical neurons in mice at postnatal day 28. Daily exposure for 4 weeks significantly reduced the number of mushroom-shaped dendritic spines in the prefrontal cortex. Prolonged exposure over 9 days gradually decreased postsynaptic density 95 puncta and inhibited neurite outgrowth in developing cortical neurons. Expression levels of genes associated with synapse formation, such as synaptic cell adhesion molecules and cyclin-dependent kinase 5, were reduced in the cerebral cortexes of exposed mice. Behavioral assessments using the Morris water maze revealed altered spatial learning and memory after the 4-week exposure period.
