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.

Researchers evaluated the effect of ELF-MFs on sleep induction in male rats using behavioral tests and oxalate acid density measurements. The results showed that the activity of rats and oxalate acid concentration reduced after ELF-MF exposure. Reduction of velocity and frequency in the open-field test was attributed to sleepiness.

Living near magnetic and electric fields from high-voltage towers threatens cognitive and behavioral health in humans and animals. These fields cause cognitive and behavioral disorders in living beings. The authors state that more research is needed because it threatens cognitive health.

Researchers assessed short-term behavioural responses of 15 juvenile thornback rays to direct and alternating 50 Hz uniform 450-μT magnetic fields using a 1-hour focal-sampling design. Magnetic fields were controlled in laboratory conditions with a custom-made Helmholtz coil device. Behavioural responses did not significantly differ between control and exposed rays during the morning period. Rays exposed to direct current magnetic fields increased their activity during the midday period. Alternating current exposure produced synchronisation patterns with high inter-individual variance.

Researchers exposed pregnant rats and their pups to EMF for 4 hours a day, 5 days a week, from the first day of pregnancy to postnatal day 42, with some groups also receiving zinc. EMF exposure significantly lowered SHANK3 and NLGN3 protein levels in the hippocampus and amygdala. Behavioural tests found no effect on social behaviour but increased anxiety and reduced activity and exploration. Zinc supplementation had a partially positive effect on female offspring but not on males. Zinc did not restore the reduced protein levels.

Researchers investigated the migration of mouse melanoma B16-F10 cells in directed current EFs (dcEFs). The transcriptome of melanoma B16-F10 cells in response to EF stimulation was analyzed using RNA sequencing. The cells migrated toward the cathode in applied dcEFs, and directional migration occurred in a voltage-dependent manner. Approximately 3000 upregulated and 2613 downregulated genes were identified under dcEF. Genes correlated with cell migration such as Serpine1, Ctgf, Fosb, and Fos were upregulated, and signaling pathways involved in cell motility were significantly altered.

Researchers investigated the effects of extremely low-frequency electromagnetic field exposure during gestational and lactational periods on immune system parameters in offspring. Significant changes were found in white blood cell and lymphocyte counts. CD4+ T cells were significantly increased in female offspring exposed to ELF-EMF, while other lymphocyte subpopulations did not change. IL-17A and IFN-γ levels increased in plasma and spleen, but IL-4 levels and IL-4 gene expression were unchanged. IL-17A gene expression was upregulated in the spleen.

Researchers investigated the effects of 50 and 60 Hz magnetic fields on ROS production, DNA damage, DNA repair, and gene expression in human SH-SY5Y neuroblastoma cells. Cells were exposed to 100 µTRMS magnetic fields for 24 hours, then assayed or treated with menadione before assay. There was suggestive evidence of a low-magnitude increase in ROS-related gene expression immediately after exposure, and 50 Hz fields reduced menadione-induced ROS levels. Magnetic field exposures did not affect cytosolic superoxide levels, DNA damage, or DNA repair rates. No firm evidence was found for differential effects between 50 and 60 Hz fields.

Antibacterial activity was measured by reduction in bacterial viable count, and apoptosis in MCF-7 breast cancer cells was assessed using annexin V-FITC and cell cycle analysis. Combined ELF-EMF and 10 µM/ml AgNPs for 2 hours achieved 100% inhibition of K. pneumonia, while either agent alone reduced viable counts in a time-dependent manner. Combination treatment significantly increased apoptosis in MCF-7 cells, shown by elevated Pre G1 phase cells, while AgNPs caused S phase arrest and ELF-EMF caused G2/M phase accumulation.

The study used a 50 Hz, 100 µT sinusoidal magnetic field and exposed NB69 cells for 30 to 120 minutes. Two anti-p53 antibodies were used to distinguish wild-type and unfolded p53 and to assess their cellular distribution. Magnetic field exposure increased p53 gene expression and wild-type p53 protein expression. Exposure also increased unfolded p53 protein expression and changed the nuclear/cytoplasmic distribution of both forms. The antiapoptotic protein Bcl-2 expression was significantly increased.

Researchers aimed to evaluate the anti-tumor effect of caffeic or chlorogenic acid combined with a moderate-strength static magnetic field on C32 melanoma cells by assessing apoptosis. Apoptosis was evaluated using flow cytometry, apoptosis-associated gene expression was determined using RT-qPCR, and caspase activity and oxidative damage markers were measured. Phenolic acids and a static magnetic field triggered apoptosis of C32 cells and affected expression of genes encoding apoptosis regulatory proteins. The study concluded that both phenolic acids and a static magnetic field can be used supportively in melanoma treatment and that caffeic acid is more pro-apoptotic than chlorogenic acid.

The study aimed to examine the 96-hour effects of ELF-EMF on HERV-H, K, and W expression in human melanoma cells. SK-MEL-37 cells were continuously exposed to ELF-EMF at 50 Hz and intensities of 1.5 and 3 mT for 96 hours, and HERV expression was measured by qPCR after mRNA extraction. Exposure to ELF-EMF for 96 hours significantly downregulated HERV-H, K, and W env gene expression (P<0.001). The researchers suggested that low intensity and long-term exposure to ELF-EMF may pave using this type of radiation as a novel therapeutic approach by neutralizing the HERVs upregulated expression in melanoma cells.

The review paper examines studies on the influence of electromagnetic fields on innate and acquired immune responses in humans, animal models, and in vitro models, and on immunity from COVID-19 infections associated with cell death. The review focuses on the effects of electromagnetic fields and the influence of oxidative stress on stimulation or immunomodulation. The review also focuses on the inflammatory response, autoimmunity, and the participation of intracellular calcium channels in COVID-19 immunology. Non-ionizing radiation can activate or reduce the inflammatory response, oxidative stress, and the entry of intracellular calcium, and can facilitate or reduce cell death.

Researchers randomly assigned pregnant Sprague-Dawley rats to a control group or a 900-MHz EMF exposure group, with the EMF group exposed daily until birth. Newborn rats were sacrificed by anesthesia on days 7, 10, 15, and 30. Structural damage in cochlear nuclear neurons and oligodendrocytes and increased caspase-3 activity were observed in the EMF groups compared to controls. However, no significant difference was found between groups in structural damage or caspase-3 activity across postnatal stages, and auditory brainstem response latencies did not differ. The authors concluded that prenatal 900-MHz EMF exposure has no harmful effects on ventral cochlear nucleus development.

Rats were exposed to 900 MHz RFR at 2 h/day, 5 days/week for 1 week (acute) or 10 weeks (chronic). The study measured histopathology, PCNA, Bcl-xL, cleaved caspase-3, p-JNK, p-p38, and TUNEL in testis tissue. No histopathological differences or PCNA changes were observed between sham and RFR groups in either period. Cleaved caspase-3 and Bcl-xL showed period-dependent alterations, TUNEL-positive cells increased significantly only after acute exposure, and both p-p38 and p-JNK protein expressions increased significantly in both acute and chronic RFR groups.
