Researchers randomly assigned adult female NMRI mice to five groups including fresh ovarian transplantation, vitrified transplantation, and vitrified transplantation with NAC, pulsed electromagnetic fields, or both. NAC, PEMF, and combined NAC+PEMF treatments significantly increased follicle numbers and vascularization in the transplanted tissue. The combined treatment also lowered malondialdehyde levels and demonstrated a synergistic effect on angiogenesis and oxidative stress protection.

Researchers exposed male Wistar rats to 27 MHz continuous shortwaves at power densities of 0, 5, 10, or 30 mW/cm2 for 6 min. They analyzed serum INSL3 and anti-sperm antibody levels, sperm motility and malformation, testicular structure, and oxidative stress markers including SOD, CAT, MDA, calpain, and Cdk5 expression at multiple time points after exposure. Exposure decreased serum INSL3 levels, increased anti-sperm antibodies, decreased percentage of class A+B sperm, increased sperm malformation, injured testicular tissue, decreased SOD and CAT activities, increased MDA content, and increased calpain1, calpain2, and Cdk5 expression in testicular tissue.

Researchers conducted a population-based case-control study in two Northern Italian provinces, including 182 childhood leukemia cases and 726 matched controls. Exposure was assessed by calculating distance from childhood residence to the nearest transformer station using a geographical information system. Living within 15 meters of a transformer station was not appreciably associated with leukemia or acute lymphoblastic leukemia risk, and similar results were found with a 25-meter buffer. Among children aged five years or older, odds ratios were 1.3 (95% CI 0.1-12.8) for leukemia and 1.3 (95% CI 0.1-12.4) for ALL with the 15-meter buffer, and 1.7 (95% CI 0.4-7.0) for leukemia and 0.6 (95% CI 0.1-4.8) for ALL with the 25-meter buffer.

Researchers divided 20 Albino-Wistar pregnant rats into EMF and control groups and selected 12 male fetuses after delivery. They assessed body growth at delivery, 21 days, and 56 days using crown-rump length, measured BDNF with an ELISA kit, and recorded body weight with a digital scale. EMF exposure blocked body growth and remarkably decreased BDNF levels in the exposed offspring compared to controls.

Researchers exposed semen samples from fertile men to radiofrequency radiation from a smartphone using 4G, 5G, or WiFi connectivity. Sperm motility and viability decreased with WiFi exposure but not with 4G or 5G exposure. The study also tested whether a cellphone case or increased distance could reduce the effects.

They assessed mobile phone radiation exposure using daily call time, phone proximity when not in use, phone models, specific absorption rate (SAR), and effective SAR (SAR × call time). Excess weight gain during pregnancy increased CAKUT risk, while folic acid use before pregnancy was protective. Longer daily call time and higher effective SAR values were associated with increased CAKUT risk, but phone proximity when not in use was not a risk factor.

Researchers exposed pregnant rats to 5G EMF at 3500 MHz continuous wave with a whole-body SAR of 0.07 W/kg for 22 hours per day from gestational day 8 to postnatal day 21. Both male and female pups showed delayed incisor eruption by one day in the exposed group compared to sham controls. In adolescent open-field testing, exposed females exhibited 70% fewer stereotyped movements while exposed males exhibited 50% more stereotyped movements than sham-exposed rats.

Researchers exposed APP/PS1 and wild-type mice to 900 MHz microwave radiation for 270 days at a SAR of 0.25-1.055 W/kg, 2 hours per day. Cognitive tests showed improved spatial and working memory in the exposed AD mice compared with sham-exposed controls. Microwave exposure did not cause Aβ plaques in wild-type mice but reduced Aβ accumulation in the cortex and hippocampus of APP/PS1 mice.

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 male mice for one week to electromagnetic pulse at 650 kV/m for 1,000 pulses and 4.9 GHz radiofrequency at 50 W/m 2 for one hour per day. They used open field test, tail suspension test, and Y-maze to assess anxiety, depression-like behavior, and spatial memory. Proteomic analysis showed hippocampal proteins enriched in glutamatergic and GABAergic synapses, and histological examination revealed autophagy-associated cell death in the amygdala.

Zebra finches trained in a four-arm maze to orient using the magnetic field became disoriented when tested in low-level (~10 nT) Larmor-frequency RF fields. When the same birds were trained under the RF field, they could orient, showing the field altered but did not remove magnetic input. Higher-intensity Larmor-frequency RF fields dramatically changed the compass response, while broadband RF fields during training or testing erased magnetic compass information.

Researchers investigated the effect of 0.138 THz radiation on dynamic neuronal growth and synaptic transmission efficiency. Cumulative 0.138 THz radiation did not cause neuronal death and promoted the dynamic growth of neuronal cytosol and protrusions. There was a cumulative effect of terahertz radiation on the promotion of neuronal growth. 0.138 THz waves improved synaptic transmission efficiency in the hippocampal CA1 region in a slow and continuous process. The improved synaptic transmission can continue for more than 10 min after terahertz radiation ends and is associated with an increase in dendritic spine density.

Researchers established a spatial memory impairment model by exposing mice to 2856-MHz RFR at thermal noise levels (≤1 °C). Glutamate release in the dorsal hippocampus CA1 region did not change significantly, while dopamine release was reduced. RFR enhanced calcium activity in glutamatergic CA1 pyramidal neurons through nonthermal mechanisms, and this activity returned to baseline after exposure ended. The dopamine reduction was linked to decreased density of dopaminergic projections from the locus coeruleus to the dorsal hippocampus. Artificially activating dopamine axon terminals or D1 receptors in the dorsal hippocampus CA1 improved memory damage in exposed mice.

Researchers used all-atom molecular dynamics simulations to investigate how terahertz waves affect the structure of Aβ42 monomer, dimer, and tetramer. Terahertz waves at 42.55 THz enhanced intramolecular interactions in the monomer and intermolecular interactions in the dimer by resonating with specific molecular vibrations. This increased β-structure content in the monomer and significantly enhanced binding energy in the dimer. Terahertz waves also mildly stabilized tetrameric protofibrils by enhancing interactions among peripheral peptides.
