The study investigated the effect of 900 MHz GSM on oxidative stress and intracellular ROS levels in human mononuclear cells, monocytes, and lymphocytes. Blood samples from 13 healthy volunteers were exposed to RF radiation from a mobile phone simulator for 2 hours, while control samples were not exposed. Mononuclear cells were isolated by density gradient centrifugation and ROS was measured using a CM-H2DCFDA fluorescence probe and flow cytometry. Results showed a significant increase in ROS production in monocyte-rich cell populations after exposure, but no significant change in lymphocyte-rich populations.

Researchers exposed pregnant rats and their offspring to 900, 1800, and 2450 MHz electromagnetic radiation for 60 minutes daily during pregnancy and growth. Uterine lipid peroxidation increased in exposed groups while glutathione peroxidase activity and prolactin levels decreased in developing rats. In maternal rats, plasma prolactin, estrogen, and progesterone decreased while total oxidant status and body temperature increased. No changes occurred in reduced glutathione, total antioxidants, or vitamins A, C, and E in maternal uterine and plasma samples.

Researchers exposed male rats to cell phone radiation (900 MHz) for one hour daily over several weeks and found significant damage to sperm quality, count, and testicular tissue structure. The radiation caused irregular sperm development, cell death, and reduced fertility markers. However, when rats were also given Moringa leaf extract (a plant rich in antioxidants), the protective compounds largely prevented this reproductive damage.

Mice were exposed to 2G and 3G radiation for 48 minutes per day over periods of 30 to 180 days. Exposed mice showed significant reductions in body weight at the first, second, and fourth months, and in testis weight and volume during the first three months. Serum testosterone levels were significantly lower in exposed mice at the first, second, third, fourth, and sixth months, with no significant difference between the 2G and 3G groups. Histological analysis revealed lower seminiferous tubule density and diameter, fewer Sertoli and Leydig cells, and microscopic changes such as wide interstitium, cell detachment, vacuolar degeneration, reduced epithelial thickness, maturation arrest, and Johnson scores of 7 to 9.

Researchers exposed rats to 2.1 GHz radiofrequency radiation (similar to cell phone frequencies) for 2 hours daily over 10 weeks and studied heart muscle cells. While basic heart function remained normal, the cells showed reduced responsiveness to stress hormones like adrenaline, and nitric oxide levels increased in heart tissue. This suggests that chronic EMF exposure may impair the heart's ability to respond properly during physical or emotional stress.

Researchers exposed young rats (equivalent to pre-adolescent humans) to 900-MHz cell phone radiation for one hour daily over 30 days, then examined their brain tissue. They found significant loss of pyramidal neurons in the hippocampus (a brain region crucial for memory and learning) and observed damaged cells with abnormal appearance. This suggests that cell phone radiation exposure during development may harm critical brain cells needed for cognitive function.

Three-month-old male Wistar rats (n=27) were exposed to 2.45 GHz radiation in a chamber with two Wi-Fi antennas and divided into a control group and groups exposed for 1 hour or 7 hours per day for two months. Sperm parameters, caspase-3 concentrations, histomorphometric changes of testis, and apoptotic indexes were evaluated. Both exposure groups showed a decrease in sperm parameters in a time-dependent pattern, increased apoptosis-positive cells and caspase-3 activity in seminiferous tubules, and significantly reduced seminal vesicle weight compared to controls.

The study aimed to determine whether short-term exposure at 1 V/m to typical GSM and UMTS signals affects cognitive performance and physiological parameters. The sample included 200 subjects, with 50.0% reporting idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF) and 50.0% non-IEI-EMF. No statistically significant differences were found between real exposure and sham exposure for cognitive performance or physiological effects in either group (P’s > 0.05).

Researchers exposed mice to 2.45 GHz HF-EMF for 60 minutes per day for 7 or 30 or 60 or 90 or 120 days. Anxiety-like behavior was assessed with the elevated plus maze, open field test, and social interaction test; OCD-like behavior with marble burying; and depression-like behavior with the forced swim test and tail suspension test. The study found no evidence that HF-EMF exposure produced anxiety, OCD, or depression-like behavior in mice up to 120 days.

Researchers conducted a single-blinded randomized counterbalanced study with 24 healthy subjects aged 18–30 years who underwent three exposure conditions. The study tested whether microwaves from an 890-MHz phone-like signal at SAR10G of 2 W/kg and 0.2 W/kg versus sham gave acute effects on brain-shielding barriers using blood serum biomarkers. Over time, statistically significant variations were found for TTR and β-trace protein, but no difference was found between exposure conditions and no interaction between exposure condition and time of blood sampling. The study concluded it failed to show any acute clinically or statistically significant effect of short-term microwave exposure on serum levels of S100β, TTR, and β-trace protein with follow-up limited to two hours.

Japanese researchers exposed developing rats' brain cortex to 1457 MHz radiofrequency radiation (similar to cell phone frequencies) for 50 minutes at 2.0 W/kg to test blood-brain barrier effects. Using advanced fluorescence microscopy, they found no changes in barrier permeability in either juvenile or young adult rats. The study suggests this specific RF exposure doesn't immediately compromise the protective barrier around the developing brain.

Researchers exposed male rats to 900 MHz mobile phone radiation for one hour daily over eight weeks and found significant damage to sperm quality, testicular tissue, and fertility markers. The study also tested whether Moringa oleifera leaf extract could protect against this damage, finding that the antioxidant-rich plant extract significantly prevented radiation-induced reproductive harm.

Researchers exposed male rats to 900 MHz mobile phone radiation for one hour daily over eight weeks, finding significant damage to sperm count, motility, and testicular tissue structure. The study also tested whether Moringa oleifera leaf extract could protect against this damage, showing that the plant extract helped preserve sperm parameters and testicular health. This adds to growing evidence that cell phone radiation may impact male fertility.

The study used Wistar Albino adult male rats divided into a sham group and an exposure group, with rats in the exposure group exposed to 2.4 GHz radiofrequency radiation for 24 hours a day during 12 months. Sperm head defects increased in the exposed group, and weight of the epididymis and seminal vesicles, seminiferous tubule diameter, and tunica albuginea thickness all decreased. Other measured parameters did not show statistically significant differences between the groups.

Researchers exposed male rats to 900-MHz electromagnetic radiation for one hour daily over 60 days, with a withdrawal group that had a 30-day recovery period. Exposure significantly increased malondialdehyde levels and decreased total antioxidant capacity in brain, liver, and kidney tissues. Serum levels of alanine transaminase, aspartate aminotransferase, urea, creatinine, and corticosterone were significantly increased, while catecholamines were not significantly changed. All these alterations were corrected after the withdrawal period.

Researchers divided 70-day-old male Wistar rats into four groups: sham exposed, melatonin treated, microwave exposed, and microwave plus melatonin treated. Exposure took place in Plexiglas cages for 2 hours a day for 45 days at a power density of 0.21 mW/cm2 and a SAR of 0.14 W/Kg. Melatonin was associated with a significant increase in testicular LDH-X and decreased levels of MDA and ROS in the testes. The researchers concluded that melatonin has strong antioxidative potential against microwave-induced oxidative stress mediated DNA damage in testicular cells.

Researchers exposed male rats to WiFi-frequency radiation (2.45 GHz) for 2 hours daily over 45 days, finding significant damage to sperm production and testosterone levels. Melatonin supplements prevented most reproductive harm, suggesting microwave radiation threatens male fertility but antioxidants may offer protection.

Previous measurements of skin dielectric properties typically included all three skin layers together. This study provides new data for the epidermis and dermis measured in vitro from 0.5 GHz to 110 GHz. The results agreed with Gabriel's data for the dermis up to 20 GHz. For 20 to 100 GHz, experimental results showed larger values than extrapolated Gabriel data. For frequencies over 20 GHz, the parametric model tends toward the experimental results for the epidermis.

Researchers exposed 30-day-old rats to 900 MHz radio waves from a mobile handset for 4 hours per day over 15 days. Exposed rats showed more anxiety and poor learning compared to control and sham groups. Antioxidant enzymes and non-enzymatic antioxidants changed significantly and lipid peroxidation increased in exposed rats.

Researchers exposed young rats to 900 MHz mobile phone radiation for 4 hours daily over 15 days and found significant brain damage in memory centers like the hippocampus. The exposed rats showed increased anxiety, poor learning ability, and cellular damage from oxidative stress (harmful molecules that damage cells). This suggests that prolonged mobile phone use may harm brain function and memory formation.
Saikhedkar N et al. · 2014
Researchers exposed young rats to 900 MHz cell phone radiation for 4 hours daily over 15 days and found significant brain damage in memory-critical areas like the hippocampus. The exposed rats showed increased anxiety, poor learning ability, and actual cell death in brain tissue, along with elevated oxidative stress (cellular damage from harmful molecules). This study demonstrates that radiofrequency radiation at levels similar to cell phones can cause measurable neurological harm and cognitive impairment.

Researchers exposed rats to 2.45 GHz wireless radiation (the same frequency as WiFi and microwave ovens) for one hour daily over 30 days and found it caused oxidative damage to testicles. When rats were given melatonin supplements alongside the radiation exposure, the antioxidant prevented most of the testicular damage. This suggests wireless radiation may harm male reproductive health through oxidative stress.

Researchers exposed male rats to 2.45 GHz radiation (WiFi frequency) for one hour daily over 30 days and found it caused oxidative damage in testicular tissue. The study showed that melatonin supplementation prevented this damage by maintaining antioxidant levels. This suggests WiFi-frequency radiation may harm male reproductive health through oxidative stress mechanisms.

French researchers exposed rats to 900 MHz cell phone radiation (with and without iron overload) and tested their spatial learning abilities. The EMF-exposed rats showed impaired object exploration and altered brain chemistry, particularly in the hippocampus, but performed normally on navigation and memory tasks. Adding iron overload didn't worsen the effects.
