Twenty-one healthy volunteers were exposed to a GSM signal at 900 MHz with specific absorption rates of 0.49 W/kg (10 g tissue) and 0.70 W/kg (1 g tissue). Delta and beta rhythms of resting EEG were not affected by the exposure. Theta brainwaves were significantly modulated during exposure, and this modulation depended on whether eyes were closed or open.

Researchers conducted a cross-sectional study of 865 adults aged 18 to 45 years who had used mobile phones for more than two years. Mean daily mobile phone use was 85.94 minutes, ranging from 4 to 900 minutes per day. No significant differences were found between dominant and non-dominant ears for wave amplitudes, latencies, or interpeak latencies overall. However, interpeak latency I-V was significantly prolonged with daily use over 180 minutes, use of 0 to 4 years, and cumulative use over 1500 hours. Mean interpeak latencies increased with years of mobile phone use and were highest in users with more than 12 years of use.

The study included 32 healthy participants in a double-blinded crossover counterbalanced design. EEG recordings were taken from 63 electrodes across 6 brain regions during two 18-minute sessions with alternating eyes-open and eyes-closed blocks. Bayesian analysis provided statistical evidence for an EMF effect on alpha band power density in the eyes-open condition.

Researchers exposed 5×FAD mice to 1950 MHz radiofrequency electromagnetic fields at 5 W/kg for two hours per day, five days per week, for six months. They conducted object recognition and Y-maze behavioral tests and analyzed amyloid precursor protein and amyloid-beta metabolism in brain tissue. Exposure for six months ameliorated cognitive impairment and amyloid-β deposition. Hippocampal expression of Iba1 and CSF1R was significantly reduced in exposed mice compared with sham-exposed mice. Both radiofrequency electromagnetic fields and a CSF1R inhibitor suppressed genes related to microgliosis and pro-inflammatory interleukin-1β.

Fifty mobile phone users aged 20–38 provided buccal cell samples from both cheeks, yielding 100 samples. Each sample of 1000 cells was stained with Feulgen and Papanicolaou methods and scored for micronuclei. Mean micronucleus counts were similar between exposed and non-exposed mucosa for both staining methods, and the differences were not statistically significant. Micronucleus frequency was 5- to 6-fold higher with non-specific DNA staining than with DNA-specific staining. No significant associations were found between micronucleus frequency and age, gender, BMI, or phone usage habits.

The study included 40 men from electrical substations, 40 men from cellular communication towers, and 40 men from control sites away from these facilities. Researchers measured oxidative stress markers TOS and MDA, antioxidant markers TAC and GSH, and thyroid hormones TSH, T3, and T4. Both worker groups had significantly elevated TOS and MDA and significantly reduced TAC and GSH, with the most significant alteration in substation workers. Thyroid function was normal in both worker groups, though TSH was significantly higher in substation workers than in the other groups.

Researchers exposed female old CD1 mice to low-frequency pulsed electromagnetic fields from the NEURALTER® system for 15 minutes daily over four weeks. Behavioral tests and analysis of peritoneal leukocytes showed that treated mice had greater coordination and locomotion, better immune function, and an oxidative-inflammatory state. Direct exposure of leukocytes to the NEURALTER® system also improved their immune function and oxidative state.

Relationship between cell-phone over-use scale with depression et al. · 2022
Researchers conducted a descriptive-analytical cross-sectional study of 212 students using the Cell-phone Over-use Scale and the Depression Anxiety Stress Scale. The sample was predominantly male (72.2%), aged 21–23 years (46.2%), and single (92.5%). Multiple linear regression showed a significant association between cell phone overuse and higher stress (t=2.614, P=0.010) and anxiety (t=2.209, P=0.028), but not depression (t=1.790, P=0.075).

Researchers created an algorithm for the MOBI-Kids study to estimate cumulative specific energy from RF fields and cumulative induced current density from ELF fields in the brain of subjects aged 10 to 24 years. The algorithm considered age, tumour location, phone models, usage patterns, and communication system prevalence over time. Median RF and ELF doses were substantially higher for GSM than 3G systems and varied considerably by brain location. Agreement between RF dose estimates and phone use variables was moderate to null depending on communication system, while agreement for ELF dose was higher but also system-dependent. Duration and number of calls may not be adequate proxies for dose as communication systems become more complex over time.

Researchers investigated the effects of ELF-EMFs on cortisol secretion in 14 men working in extra-high voltage substations. Magnetic field exposure was measured over seven days with geometric means ranging from 0.1 to 2.6 μT. Blood samples were taken hourly from 20:00 to 08:00 the next morning. Compared to unexposed controls, higher field intensity had a significant effect on cortisol secretory pattern. This study strongly suggests that chronic exposure to ELF-EMFs alters peak-time serum cortisol levels.

Researchers assessed the effects of ELF-MF therapy on chronic pain in 49 patients with musculoskeletal disorders. Patients received eight 45-minute sessions every other day using a Quec Phisis setup generating ion cyclotronic resonance. Bioimpedance (R/h and Xc/h) was measured during the first and last sessions, and pain perception was quantified using the standard visual-analog scale. Both bioimpedance parameters increased significantly and pain perception decreased. The authors concluded that ELF-MF therapy appears a valid therapeutic approach for musculoskeletal pain.

In a single-blind, sham-controlled, randomized crossover study, 15 normal-weight young men were exposed to 25 minutes of RF-EMFs from two mobile phone types or sham radiation under fasting conditions. Spontaneous food intake was measured with an ad libitum buffet test and cerebral energy homeostasis was monitored using phosphorus-31 magnetic resonance spectroscopy. Exposure increased overall caloric intake by 22–27% compared to sham, mainly due to higher carbohydrate consumption, and cerebral energy content increased as shown by higher ATP and phosphocreatine ratios to inorganic phosphate.

Researchers estimated all-day and evening whole-brain radiofrequency electromagnetic field doses from phone calls, screen activities, and far-field sources in preadolescents aged 9 to 12 years from two birth cohorts. Sleep disturbances were assessed via a maternal questionnaire and objective sleep measures were recorded using wrist accelerometers and sleep diaries for seven consecutive days. All-day whole-brain RF-EMF doses were not associated with self-reported sleep disturbances or objective sleep measures, while high evening whole-brain RF-EMF dose from phone calls was associated with 11.9 minutes less total sleep time.

Normal sperm samples were divided into control and case groups, with case samples placed 2.5 cm from an active cell phone antenna for 60 minutes. Control samples were exposed to cell phones without active antennas. Viability and motility were significantly lower in the case group, while apoptotic sperm percentage and DNA fragmentation were significantly higher. Morphology, chromatin abnormality, and maturity showed no significant difference between groups.

Researchers evaluated cytological effects of prolonged mobile phone usage on buccal mucosa of 90 children divided into three groups by daily usage hours. Buccal swabs were collected using an ice-cream stick method and analyzed histologically and microscopically with one-way ANOVA. Group 3 with more than six hours daily usage showed the highest number of cellular and chromosomal aberrations, a significant finding. A direct proportionality was observed between apoptotic changes, chromosomal aberrations, and daily hour usage.

Eighty-one students were categorized into three groups based on daily mobile phone use: less than 20 minutes, 20 to 60 minutes, and more than 60 minutes. Salivary flow rate, IgA, and thiol levels showed no statistically significant differences among the three groups. Malondialdehyde (MDA) levels differed significantly across groups, with a significant pairwise difference between the 20–60 minute and over 60 minute groups.

Researchers surveyed 268 residents in a Madrid neighborhood surrounded by nine telephone antennas and took 105 electromagnetic radiation measurements with a spectrum analyzer and isotropic antenna both outside and inside homes. The study found statistically significant associations between radiation exposure and headaches, nightmares, dizziness, instability episodes, sleep duration, and tiredness parameters. Cancer prevalence in the study population was 5.6%, which is 10 times higher than the general Spanish population.

Researchers conducted a systematic literature search in PubMed and EMF-Portal through January 2019 and identified 15 articles published between 1997 and 2019. Eight principal investigators expressed willingness to provide their original data for a pooled analysis. A pooled study would have more than 80% power to detect a relative risk of 1.14 or higher for ALS and occupational ELF-MF exposure.
