This chemistry/engineering study reports the synthesis and NMR/MRI-relevant characterization of a trinuclear Gd(III) chelate intended for high-field MRI contrast applications. Using 17O NMR and proton relaxivity across multiple fields and temperatures, the authors infer bishydration, quantify water exchange and…

This paper describes an exposure and microscopy system designed to continuously observe living cells during exposure to modulated RF-EMF similar to mobile phone signals. Using protocols where the same cells serve as controls before and after exposure, the system was validated with endocytosis measurements. Under 900…

This paper describes a system intended to encourage daily walking exercise in people with COPD. During home exercise, the platform sends SMS messages to the patient's mobile phone indicating the target exercise intensity (linked to music tempo). The abstract does not report any findings about health outcomes or…

This study reports measurements in 25 dental patients treated with the Viofor JPS system using extremely low frequency magnetic fields. Following a series of treatments, oral cavity electropotentials decreased and saliva pH increased. Copper levels in non-stimulated saliva decreased, while other measured elements…

This exposure assessment measured peak magnetic fields during magnetic particle inspection, a nondestructive testing method that uses electromagnetism. Ninety-five peak measurements taken while inspecting 8 turbine engine shafts ranged from

This study reports on symptomatology and risk perception among 45 people living near power-lines in the Benevento area. Although measured electric and magnetic fields were described as being within the normal range, participants reported symptoms mainly in subjective and behavioural domains. The authors argue that…

This in vitro study measured biophoton/chemiluminescence emission from MDCK cells after inducing reactive oxygen species with hydrogen peroxide. The authors report that photon emission increased with hydrogen peroxide dose and that photomultiplier tube measurements agreed with fluorescence microscopy observations.…

This laboratory study examined whether a weak alternating magnetic field tuned to the cyclotron frequency of Ca2+ and K+ ions influences fusion of tobacco and soya protoplasts. The abstract reports a 2–3× increase in protoplast fusion frequency under exposure. It also reports involvement of calcium ions in induction…

This study measured satellite structures of second- and third-harmonic spectra reflected from solid targets during femtosecond laser–plasma interactions using an optical multi-channel spectrometer. Red-shifted satellite structures of 2ω0 and 3ω0 were observed, and at ~10^18 W/cm^2 the inferred spontaneous magnetic…

This paper describes a modified approach for assessing occupational EMF exposure during work on radio and television towers and masts, where exposure can be high and tasks/routes are not fixed. The method calculates maximum admissible dwell time at different mast levels while incorporating the EMF dose accumulated…

This paper models extravascular MRI signal decay (R2/R2*) as a function of blood oxygenation, vessel geometry, and magnetic field strength up to 9.4 T using Monte Carlo diffusion simulations. It reports different vessel-size dependencies for Hahn-spin-echo versus gradient-recalled-echo relaxation across field…

This randomized animal study tested whether pulsed electromagnetic field (PEMF)-induced vibration affects orthodontic tooth movement produced by magnetic and/or mechanical forces. Forty-four Wistar rats were exposed to PEMF-induced vibration or normal atmosphere while tooth movement was induced using magnets and/or…

This paper studies chaotic mixing driven by breakup and reformation of a magnetic particle chain under a rotating magnetic field using direct numerical simulation. The authors report that chain motion and the degree of chaos depend strongly on the Mason number, and that a limited Mason number range produces repeated…

This paper reports analytical theory on how a small solenoidal magnetic field affects an ion-beam pulse propagating through background plasma. The authors predict enhanced self-electric and self-magnetic fields under a resonance-like condition (omegace ≈ omegape beta_b) attributed to a dynamo effect. The combined…
