Extremely low‐frequency magnetic fields and risk of childhood leukemia: A risk assessment by the ARIMMORA consortium
Exposure to extremely low‐frequency magnetic fields (ELF‐MF) was evaluated in an International Agency for Research on Cancer (IARC) Monographs as “possibly carcinogenic to humans” in 2001, based on increased childhood leukemia risk observed in epidemiological studies. We conducted a hazard assessment using available scientific evidence published before March 2015, with inclusion of new research findings from the Advanced Research on Interaction Mechanisms of electroMagnetic exposures with Organisms for Risk Assessment (ARIMMORA) project. The IARC Monograph evaluation scheme was applied to hazard identification. In ...

Effects of exposure to gradient magnetic fields emitted by nuclear magnetic resonance devices on clonogenic potential and proliferation of human hematopoietic stem cells
This study investigates effects of gradient magnetic fields (GMFs) emitted by magnetic resonance imaging (MRI) devices on hematopoietic stem cells. Field measurements were performed to assess exposure to GMFs of staff working at 1.5 T and 3 T MRI units. Then an exposure system reproducing measured signals was realized to expose in vitro CD34+ cells to GMFs (1.5 T‐protocol and 3 T‐protocol). CD34+ cells were obtained by Fluorescence Activated Cell Sorting from six blood donors and three MRI‐exposed workers. Blood donor CD34+ cells were exposed in vitro for 72 h to 1.5 T or 3 T‐protocol and to sham procedure. Cells...

Disturbed sleep in individuals with Idiopathic environmental intolerance attributed to electromagnetic fields (IEI‐EMF): Melatonin assessment as a biological marker
In this study, we compared levels of melatonin between a sensitive group (IEI‐EMF, n = 30) and a non‐sensitive control group (non IEI‐EMF, n = 25) without exposure to electromagnetic sources. Three questionnaires were used to evaluate the subjective quality and sleep quantity: the Epworth Sleepiness Scale, the Pittsburgh Sleep Quality Index and the Spiegel Sleep Inventory. Melatonin was quantified in saliva and its major metabolite 6‐sulfatoxymelatonin (aMT6s) in urine. Melatonin levels were compared by a two‐way analysis of variance at various times between the control and IEI‐EMF group. Despite signif...

Microwave fields have little effect on α‐synuclein aggregation in a Caenorhabditis elegans model of Parkinson's disease
Potential health effects of radiofrequency (RF) radiation from mobile phones arouse widespread public concern. RF fields from handheld devices near the brain might trigger or aggravate brain tumors or neurodegenerative diseases such as Parkinson's disease (PD). Aggregation of neural α‐synuclein (S) is central to PD pathophysiology, and invertebrate models expressing human S have helped elucidate factors affecting the aggregation process. We have recently developed a transgenic strain of Caenorhabditis elegans carrying two S constructs: SC tagged with cyan (C) blue fluorescent protein (CFP), and SV with the Venus (V) var...

Effect of weak permanent magnetic field on lipid composition and content in perilla leaves
Composition and content of lipids were studied in leaves of red perilla plants (Perilla nankinensis [Lour.] Decne.) grown in weak permanent horizontal magnetic field (PMF) of 500 µT flux density under controlled illumination, temperature, and humidity in the phytothron chamber. Control plants were grown under similar conditions, but without PMF exposure. Exposure of perilla plants for a month to PMF retarded plant flowering as compared to control. PMF treatment increased total lipid content, including polar lipids, among them glycolipids and phospholipids. PMF did not affect content of neutral lipids. It is concluded th...

Observations from national Italian fixed radiofrequency monitoring network
We analyzed a database of more than 50 million data points from the national Italian fixed radiofrequency (RF) field monitoring network that was operational between June 2002 and November 2006. We applied a modified Regression on Order Statistics approach to reanalyze the database and to deal with the large proportion of entries (39.8%) below detection sensitivity of the probe systems. We found no more than an 18% variation in annual wideband levels during the 2002–2006 period. Mean value for mobile communications band was 0.047 μW/cm2 for the period 2005–2006. Findings of this analysis are consistent with similar p...

Schwann‐like cells differentiated from human dental pulp stem cells combined with a pulsed electromagnetic field can improve peripheral nerve regeneration
The purpose of this study was to investigate the effect of Schwann‐like cells combined with pulsed electromagnetic field (PEMF) on peripheral nerve regeneration. Schwann‐like cells were derived from human dental pulp stem cells (hDPSCs) and verified with CD104, S100, glial fibrillary acidic protein (GFAP), laminin, and P75NTR immunocytochemistry. Gene expression of P75NTR and S100 were analyzed. Male Sprague‐Dawley rats (200‐250g, 6‐week‐old) were divided into seven groups (n = 10 each): control, sham, PEMF, hDPSCs, hDPSCs + PEMF, Schwann‐like cells, Schwann‐like cells + PEMF. Cells were transpl...

Drone based measurement system for radiofrequency exposure assessment
For the first time, a method to assess radiofrequency (RF) electromagnetic field (EMF) exposure of the general public in real environments with a true free‐space antenna system is presented. Using lightweight electronics and multiple antennas placed on a drone, it is possible to perform exposure measurements. This technique will enable researchers to measure three‐dimensional RF‐EMF exposure patterns accurately in the future and at locations currently difficult to access. A measurement procedure and appropriate measurement settings have been developed. As an application, outdoor measurements are performed as a functi...

Pulsed electromagnetic fields promote in vitro osteoblastogenesis through a Wnt/β‐catenin signaling‐associated mechanism
Substantial evidence indicates that pulsed electromagnetic fields (PEMF) could accelerate fracture healing and enhance bone mass, whereas the unclear mechanism by which PEMF stimulation promotes osteogenesis limits its extensive clinical application. In the present study, effects and potential molecular signaling mechanisms of PEMF on in vitro osteoblasts were systematically investigated. Osteoblast‐like MC3T3‐E1 cells were exposed to PEMF burst (0.5, 1, 2, or 6 h/day) with 15.38 Hz at various intensities (5 Gs (0.5 mT), 10 Gs (1 mT), or 20 Gs (2 mT)) for 3 consecutive days. PEMF stimulation at 20 Gs (2 m...

Factors to consider when applying transcranial magnetic stimulation of dorsolateral prefrontal cortex when resting motor threshold is asymmetric: A case study
This study highlights the importance of tailoring DLPFC treatment intensity not only based on RMT at the M1 hand, and upon the degree to which SCD distance differs between sites, but also based upon size, shape, and density of M1 hand, as well as electric field distribution.

Parallel β‐sheet vibration band increases with proteins dipole moment under exposure to 1765 MHz microwaves
Effects of exposure of 4 h to mobile phones microwaves at 1765 MHz at a power density around 940 mW/m2 on four typical proteins (hemoglobin in H2O solution, and myoglobin, bovine serum albumin, and lysozyme in D2O solution) were studied by means of Fourier Transform Infrared spectroscopy and Fourier self‐deconvolution analysis. Increase in intensity of parallel β‐sheet component around 1635 cm−1 was observed after exposure of hemoglobin, myoglobin, and bovine serum albumin, showing that a mechanism of unfolding occurred after exposure, whereas no appreciable change in the amide I region occurred after lysozy...

Extremely low frequency magnetic fields regulate differentiation of regulatory T cells: Potential role for ROS‐mediated inhibition on AKT
Our previous studies showed that extremely low frequency magnetic fields (ELF‐MFs) inhibited tumor growth and change proportion of splenic regulatory T cells (Treg cells). Here, we focus on the effect of ELF‐MFs on lung metastatic melanoma mouse model and the regulatory mechanism of ELF‐MFs on the differentiation of Treg cells. Tumor‐bearing mice were exposed to sham ELF‐MFs and ELF‐MFs (0.4 T, 7.5 Hz) 2 h/day for 27 days. Metastatic tumor burden of lung was significantly decreased after ELF‐MF treatment. Compared to the control group, expressions of matrix metalloproteinase (MMP2, MMP9) and forkhead bo...
