Scientists exposed human and rat brain cells to 918 MHz radiofrequency radiation (similar to cell phone frequencies) in the presence of Alzheimer's-related toxic proteins. The EMF exposure reduced harmful cellular damage and oxidative stress caused by these proteins. The researchers suggest this frequency might have therapeutic potential for treating Alzheimer's disease.

Researchers exposed human and rat brain cells (astrocytes) to 918 MHz radiofrequency radiation - the same frequency range as mobile phones - while the cells were under stress from Alzheimer's-related toxins. The EMF exposure reduced harmful cellular damage and oxidative stress caused by these toxins. This suggests mobile phone radiation might have protective effects against Alzheimer's disease processes.

Researchers exposed rats to 900 MHz EMF for 2 hours daily over 8 weeks and measured effects on male reproductive parameters. EMF exposure significantly decreased sperm count, viability and motility and increased sperm deformities. EMF-exposed rats showed significant reductions in serum inhibin B and testosterone along with elevated activin A, follicle-stimulating hormone, luteinizing hormone and estradiol concentrations. Testicular StAR protein, c-kit mRNA expression, and activities of 3β- and 17β-hydroxysteroid dehydrogenases were significantly attenuated after EMF exposure. Spermine administered at 2.5 mg/Kg/day intraperitoneally for 8 weeks prevented EMF-induced alterations in sperm and hormone profiles, StAR and c-kit expression, and androgenic enzyme activities.

Researchers exposed male mice to 905 MHz radiofrequency radiation (similar to cell phone frequencies) for up to 5 weeks, finding significant DNA damage and reduced sperm quality. While sperm could still fertilize eggs, the radiation caused oxidative stress and fragmented sperm DNA at levels comparable to everyday wireless device exposure.

Researchers exposed rats to 900 MHz electromagnetic fields (similar to cell phone frequencies) for 2 hours daily over 8 weeks and found significant damage to sperm quality, hormone levels, and testicular function. However, when rats were given spermine (a natural compound), it protected against most of the EMF-induced reproductive damage. The study suggests EMF exposure disrupts male fertility through oxidative stress and inflammation.

Researchers exposed male rats to 900 MHz electromagnetic fields (similar to cell phone frequencies) for 2 hours daily over 8 weeks and found significant damage to sperm quality, hormone levels, and testicular function. However, when rats were given spermine (a naturally occurring compound), it protected against most of the EMF-induced reproductive damage. This suggests that certain protective compounds might help counteract EMF effects on male fertility.

Researchers exposed rats to 900, 1800, and 2100 MHz radiofrequency radiation for 2 hours daily over 6 months. Exposure increased oxidative stress markers including TOS, OSI, MDA, and 8-OHdG, while decreasing total antioxidant status. DNA damage measured by comet assay showed higher tail intensities in exposed groups.

Researchers exposed rats to cell phone frequencies (900, 1800, and 2100 MHz) for 2 hours daily over 6 months and found significant DNA damage and oxidative stress in testicular tissue. The higher frequencies (1800 and 2100 MHz) caused more severe DNA breaks, while all frequencies increased harmful oxidative markers and decreased protective antioxidants. This suggests prolonged cell phone radiation exposure may damage reproductive tissue at the cellular level.

Researchers exposed fresh adventitious onion roots to continuous electromagnetic fields at 2350 MHz for one, two, or four hours. Cytotoxicity was evaluated through mitotic index, phase index, and chromosomal aberrations, while genotoxicity was assessed via comet assay measuring head DNA, tail DNA, tail moment, and olive tail moment. Mitotic index increased significantly after four hours and chromosomal aberrations increased after two hours or more, while phase index showed no specific changes. Head DNA and tail DNA percentages changed significantly after two and four hours respectively, but tail moment and olive tail moment did not change significantly.

Researchers exposed fresh onion roots to 2100 MHz electromagnetic fields for 1 hour and 4 hours and measured mitotic index, chromosomal aberrations, and DNA damage using the comet assay. After 4 hours of exposure, mitotic index and chromosomal aberration percentage increased significantly compared to controls. DNA damage was indicated by a significant decrease in head DNA and increase in tail DNA after 4 hours, while tail moment and olive tail moment did not change significantly. Post-exposure evaluation after 24 hours showed no significant recovery or change.

Researchers exposed rats to cell phone radiation at 900, 1800, and 2100 MHz frequencies for 2 hours daily over 6 months and found significant DNA damage and oxidative stress in testicular tissue. The higher frequencies (1800 and 2100 MHz) caused the most severe effects, including DNA strand breaks and reduced antioxidant defenses. This suggests prolonged cell phone use may pose reproductive health risks for men.

A Wi-Fi router was used as a source of microwaves and bacterial cells were exposed continuously for 24 and 48 hours. Antibiotic susceptibility was tested by disc diffusion on Müller Hinton agar, motility of Escherichia coli O157H7 was assessed on motility agar, and metabolic activity and biofilm formation were measured with MTT assay and crystal violet quantification. Exposure altered motility and antibiotic susceptibility of Escherichia coli O157H7, did not change antibiotic susceptibility of Staphylococcus aureus or Staphylococcus epidermis, and increased metabolic activity and biofilm formation in Escherichia coli O157H7, Staphylococcus aureus and Staphylococcus epidermis.

Researchers exposed adult male Wistar albino rats to electromagnetic field radiation for 60 minutes per day for 28 days and assessed spinal cords using stereological, biochemical, and histological methods. The electromagnetic field group had fewer motor neurons and higher superoxide dismutase levels than the control group. Thymoquinone treatment increased motor neuron numbers and decreased superoxide dismutase activity compared to the electromagnetic field group.

Turkish researchers exposed rats to 900 MHz cell phone radiation for one hour daily over 28 days and found significant damage to spinal cord motor neurons. The study also tested whether thymoquinone, a natural antioxidant compound, could protect against this damage and found it successfully prevented the neurological harm. This suggests cell phone radiation may affect the nervous system beyond just the brain.

Three-week-old male Sprague Dawley rats were divided into control, pseudo-exposed, and EMF groups, with the EMF group receiving a 900-MHz EMF for 1 hour per day for 25 days. Following exposure, behavioral tests were performed for seven days before the animals were euthanized and their brains removed. Brain sections were stained with toluidine blue and pyramidal neuron numbers in CA1, CA2-3, and hilus and granule neuron numbers in the dentate gyrus were estimated using optical fractionation. The EMF group showed statistically higher numbers of both pyramidal and granule neurons than the pseudo-exposed group, and histopathological examination revealed cytoplasmic disruption in those neurons.

Researchers exposed three groups of rats to 1,800-MHz EMF for 6, 12, or 24 hours daily for 20 days during prenatal development. On postnatal day 60, liver tissue and blood were analyzed for biochemical and histological changes. Exposed groups showed significantly higher malondialdehyde levels and lower glutathione levels compared to controls. Serum calcium, alanine transaminase, and aspartate aminotransferase were elevated, while liver tissue total oxidant status increased and total antioxidant status decreased. Histology revealed extensive vacuolation and degeneration of hepatocytes, and the authors concluded that intrauterine liver damage persists into puberty.

Researchers exposed pregnant rats to 1,800-MHz electromagnetic fields (similar to cell phone frequencies) for up to 24 hours daily during pregnancy. When the offspring reached puberty, their livers showed significant damage including cellular degeneration, oxidative stress, and enzyme abnormalities. This suggests that EMF exposure during pregnancy can cause lasting liver damage that persists into adolescence.

Researchers exposed pregnant rats to 1,800-MHz electromagnetic fields (cell phone frequency) for different durations daily throughout pregnancy. When the offspring reached 60 days old, their livers showed significant damage including increased oxidative stress, reduced antioxidants, elevated liver enzymes, and cellular degeneration. This study demonstrates that EMF exposure during pregnancy can cause lasting liver damage that persists into the offspring's adult life.

The effect of Wi-Fi electromagnetic waves on neuronal response properties in rat barrel cortexSistani S et al. · 2019
Researchers exposed 29 male Wistar rats to Wi-Fi radiation for 1 hour and recorded neuronal responses in the barrel cortex. Wi-Fi radiation decreased the condition test ratio for ON responses. Spontaneous activity and ON and OFF responses were not significantly changed. The researchers concluded that Wi-Fi radiation could modulate integrative responses to natural stimuli in barrel cortex.

Researchers exposed type 2 diabetic rats to 900 MHz electromagnetic radiation from a GSM antenna for 24 hours per day over 28 days. Male Sprague-Dawley rats were divided into four groups of twelve: control rats, normal rats exposed to radiation, diabetic rats, and diabetic rats exposed to radiation. Radiation exposure nonsignificantly reduced hyperglycemia and hyperinsulinemia in diabetic rats compared to unexposed diabetic rats. Radiation exposure increased hepatic malondialdehyde and Nrf-2 levels and superoxide dismutase and catalase activities but decreased phosphorylated Akt-2 in diabetic rats.

Researchers exposed mice to pulsed LTE 1846 MHz downlink signals from gestation day 13.5 to postnatal day 21 at SARs of 0.5 or 1 W/kg. Behavioral tracking measured locomotor, drinking, and feeding behavior in the home cage from 12 to 28 weeks of age. Exposure at 0.5 W/kg significantly decreased drinking frequency and distance moved compared to sham controls. Exposure at 1 W/kg significantly increased drinking frequency and moving duration compared to sham controls.
