Bone Morphogenetic Protein-2 Signaling in the Osteogenic Differentiation of Human Bone Marrow Mesenchymal Stem Cells Induced by Pulsed Electromagnetic Fields

Unknown authors · 2020

The study investigated molecular events associated with the synergistic activity of PEMFs and BMP2 on osteogenic differentiation. Human MSCs were exposed to PEMFs at 75 Hz and 1.5 mT in combination with BMP2 at the minimal dose able to induce differentiation. Researchers analyzed changes in BMP signaling pathway gene expression and phosphorylation of downstream proteins including SMAD1/5/8 and MAPK. Results showed synergistic activity on osteogenic differentiation transcription factors and markers, with increased BMP2, BMP6, and BMP type I receptor gene expression and activation of SMAD1/5/8 and p38 MAPK.

Extremely Low Frequency Electromagnetic Fields Alter Expression of C- Myc and circ-CCDC66 in Gastric Cancer Cell Line

Unknown authors · 2020

Researchers exposed AGS cells to extremely low-frequency magnetic fields at different flux densities for 18 hours, both continuously and discontinuously. They used real-time PCR to measure changes in c-Myc and circ-CCDC66 expression. Discontinuous magnetic fields reduced c-Myc expression. Continuous exposure at 0.25 mT also reduced c-Myc expression, but higher flux densities increased it. circ-CCDC66 expression decreased under both continuous and discontinuous exposure.

Electromagnetic field of extremely low frequency has an impact on selected chemical components of the honeybee

Unknown authors · 2020

Researchers aimed to demonstrate the effect of ELF-EMF on selected chemical components of honeybees using FTIR spectroscopy. Honeybees were exposed to 50 Hz EMF at 1.6 mT for durations of 2, 6, 12, 24, and 48 hours. FTIR analysis revealed that exposure longer than 2 hours induced changes in the structure of chemical compounds, especially in regions corresponding to DNA, RNA, phospholipids, and protein vibrations, compared to unexposed controls.

Chromosome aberration in typical biological systems under exposure to low- and high-intensity magnetic fields

Unknown authors · 2020

Researchers investigated chromosome response in human neuronal-like cells and plant roots (Allium sativum and Vicia faba) exposed to static and 50 Hz magnetic fields at intensities from 1 mT to 0.8 T. FTIR spectroscopy showed a significant decrease in phosphate band intensity in DNA after exposure of neuronal-like cells to 1 mT static and 50 Hz fields, suggesting chromatin uncoiling and unpackaging. Microscopy directly observed this effect in Allium sativum and Vicia faba roots exposed to a 0.8 T static magnetic field.

Effect of low frequency magnetic field on efficiency of chromosome break repair

Burgos-Molina AM et al. · 2020

Researchers studied the repair of DNA double strand breaks in Saccharomyces cerevisiae under magnetic field exposure. They induced pairs of DSB using HO endonuclease by plating cells on galactose-containing media. The repair processes occurred during 21 days of exposure to a 50Hz, 2.45mT sinusoidal magnetic field generated by Helmholtz coils. Magnetic field exposure increased colony formation 1.29-fold for Pho91 and 1.5-fold for Rmd5 at day 21 compared to untreated controls. DNA repair kinetics showed a 55.56-fold increase at day 15 for Rmd5 versus a 1.18-fold increase for Pho91.

Double- strand breaks in lymphocyte DNA of humans exposed to [ 18 F]fluorodeoxyglucose and the static magnetic field in PET/MRI

Unknown authors · 2020

Thirty-two healthy young volunteers were allocated to three arms and exposed to [18F]FDG alone, a 3-T SMF alone, or both combined over 60 minutes at a PET/CT or PET/MRI system. Absorbed doses to lymphocytes exposed to [18F]FDG over 60 to 120 minutes varied between 1.5 and 3.3 mGy. The radiotracer caused a significant median relative increase of 28% in the rate of lymphocytes with at least one γH2AX focus relative to background, while the SMF alone did not. Simultaneous application of both agents did not result in a significant synergistic or antagonistic outcome.

The effect of vitamin E and C on comet assay indices and apoptosis in power plant workers: A double blind randomized controlled clinical trial

Unknown authors · 2020

The trial enrolled 81 thermal power plant employees between July and November 2017 and randomly assigned them to four groups receiving vitamin E, vitamin C, both vitamins, or no intervention. Comet assay measurements showed that tail intensity and tail length decreased in the vitamin E group, and all comet assay indices except DNA damage index decreased in the combined and vitamin C groups, whereas the control group showed no significant change. Flow cytometry analysis found no change in early apoptosis, late apoptosis, or necrosis in any group after the intervention.

Evaluation of frequency magnetic field, static field, and Temozolomide on viability, free radical production and gene expression (p53) in the human glioblastoma cell line (A172) Electromagn Biol Med 39: 298-309, 2020

Exposure to Electromagnetic Field during Gestation Adversely Affects the Electrophysiological Properties of Purkinje Cells in Rat Offspring

Haghani M et al. · 2020

During all days of pregnancy, rats in the EMF-exposed group were exposed to 900 MHz pulsed-EMF radiation for 6 h per day. The exposure group demonstrated reduced spontaneous firing associated with upward and rightward shift in I/V curve compared to the control rats, and the peak amplitude of the current for the exposure pups also revealed a significant decrement. The reversal potential was +40 mV and +20 mV for the control and RF-EMF groups, respectively and showed significant differences between the two groups.

Effect of Radiofrequency Electromagnetic Fields on Thermal Sensitivity in the Rat

Unknown authors · 2020

Rats were exposed to RF-EMF for four weeks at 0, 1.5, or 6 W/kg, or kept as cage controls. Once a week they received NMDA or saline injections before a two-temperature choice test between 50°C and 28°C. In control and sham rats, NMDA reduced latency to escape heat by 45% compared to saline. Heat avoidance increased by 40% in the 6 W/kg group compared to sham. The RF-EMF effect on heat avoidance was abolished after NMDA treatment.

Effects of electromagnetic fields from long-term evolution on awake electroencephalogram in healthy humans

Nakatani-Enomoto S et al. · 2020

Researchers studied the effects of LTE-like electromagnetic fields for 30 min on awake EEG. Thirty-eight healthy volunteers aged 20 to 36 years participated. The maximum local specific absorption rate averaged over 10-g mass was 2.0 W/kg. Theta and alpha band waves were enhanced after both real and sham exposures, which the authors suggested may be due to participant drowsiness. The study concluded that LTE-like exposure for 30 min showed no detectable harmful effects on awake EEG in healthy humans.

Estimated whole-brain and lobe-specific radiofrequency electromagnetic fields doses and brain volumes in preadolescents

Unknown authors · 2020

Researchers conducted a cross-sectional analysis of 2,592 preadolescents aged 9 to 12 years from the Generation R Study in Rotterdam. An integrated model estimated whole-brain and lobe-specific RF-EMF doses from sources such as mobile and DECT phone calls, other mobile phone uses, tablet use, laptop use, and far-field sources. Overall whole-brain and lobe-specific RF-EMF doses from all sources together, from mobile and DECT phone calls, and from far-field sources were not associated with global, cortical, or subcortical brain volumes. A higher whole-brain dose from mobile phone use for internet browsing, e-mailing, and text messaging, tablet use, and laptop use while wirelessly connected to the internet was associated with a smaller caudate volume.

Prenatal and early postnatal exposure to radiofrequency waves (900 MHz) adversely affects passive avoidance learning and memory

Azimzadeh M et al. · 2020

Researchers exposed pregnant Sprague-Dawley rats and their pups to 900 MHz radiofrequency waves from a base transceiver station antenna during gestation or the first 21 days after birth for 2 h/d or 4 h/d. Passive avoidance learning and memory were assessed in 45-day-old pups with a shuttle box, and hippocampal histomorphology was examined. All exposed subgroups showed impaired passive avoidance learning and memory, the prenatal exposure group had the greatest deficit, and a mild decrease in pyramidal cell density was seen in exposed subgroups I and III.
