Occupational exposure to extremely low ‐frequency magnetic fields and the risk of ALS: A systematic review and meta‐analysis
We performed a meta‐analysis to examine associations of occupational exposure to extremely‐low frequency magnetic fields (ELF‐MF) with amyotrophic lateral sclerosis (ALS). Epidemiologic studies were identified in EMBASE and MEDLINE, in reference lists and a specialist database. We included studies that reported risk estimates of ALS in association with occupational ELF‐MF exposure. Summary relative risks (RR) or odds ratios (OR) were obtained with random effect meta‐analysis, and analyses were stratified by type of exposure assessment. This was done to evaluate whether observed heterogeneity between studies could...

Calibration and non ‐orthogonality correction of three‐axis Hall sensors for the monitoring of MRI workers' exposure to static magnetic fields
A Magnetic Resonance Imaging (MRI) scanner uses three different electromagnetic fields (EMF) to produce body images: a static permanent magnetic field (MF), several pulsed magnetic gradients, and a radiofrequency pulse. As a result, any occupation that includes an MRI exposes workers to a strong MF. The World Health Organization has now given the monitoring of occupational EMF exposure a high priority. One design for a low‐cost, compact MF exposure monitor (« MR exposimeter ») uses a set of three orthogonally assembled Hall sensors. However, at such a strong EMF exposure intensity, the non‐linearity and non‐orthogo...

Uniform magnetic targeting of magnetic particles attracted by a new ferromagnetic biological patch
A new non‐toxic ferromagnetic biological patch (MBP) was designed in this paper. The MBP consisted of two external layers that were made of transparent silicone, and an internal layer that was made of a mixture of pure iron powder and silicon rubber. Finite‐element analysis showed that the local inhomogeneous magnetic field (MF) around the MBP was generated when MBP was placed in a uniform MF. The local MF near the MBP varied with the uniform MF and shape of the MBP. Therefore, not only could the accumulation of paramagnetic particles be adjusted by controlling the strength of the uniform MF, but also the distribution ...

Pulsed electromagnetic field improves subchondral bone microstructure in knee osteoarthritis rats through a Wnt/ β‐catenin signaling‐associated mechanism
Pulsed electromagnetic field (PEMF) is often used for management of osteoarthritis (OA). The aim of the study was to determine whether PEMF can successfully improve subchondral bone microstructure through a Wnt/β‐catenin signaling‐associated pathway in rats with knee OA induced by low‐dose monosodium iodoacetate (MIA). Seventy‐two 12‐week‐old male Sprague–Dawley rats were randomly assigned to three groups: OA (n = 24), PEMF (n = 24), and Control (n = 24). OA was induced (OA and PEMF groups) by injecting 0.2 mg MIA in rats’ right knee joint. The control rats received a single sterile saline in...

Extremely high ‐frequency electromagnetic radiation enhances neutrophil response to particulate agonists
The growing use of extremely high‐frequency electromagnetic radiation (EHF EMR) in information and communication technology and in biomedical applications has raised concerns regarding the potential biological impact of millimeter waves (MMWs). Here, we elucidated the effects of MMW radiation on neutrophil activation induced by opsonized zymosan or E. coli in whole blood ex vivo. After agonist addition to blood, two samples were prepared. A control sample was incubated at ambient conditions without any treatment, and a test sample was exposed to EHF EMR (32.9–39.6 GHz, 100 W/m2). We used methods that allowed us to ...

Effects of exposure to electromagnetic field from 915 MHz radiofrequency identification system on circulating blood cells in the healthy adult rat
We investigated whether exposure to the 915 MHz radiofrequency identification (RFID) signal affected circulating blood cells in rats. Sprague–Dawley rats were exposed to RFID at a whole‐body specific absorption rate of 2 W/kg for 8 h per day, 5 days per week, for 2 weeks. Complete blood counts were performed after RFID exposure, and the CD4+/CD8+ ratio was determined by flow cytometry. The number of red blood cells (RBCs) and the values of hemoglobin, hematocrit, and RBC indices were increased in the RFID‐exposed group compared with those in the cage‐control and sham‐exposed groups (P < 0.05). Howeve...
