PubMed: RF-EMF health
Dec 26, 2025
This PubMed-listed study models how RF electromagnetic waves interact with a simplified three-layer tissue structure (skin–fat–muscle) across common ISM bands (433, 915, 2450, 5800 MHz), varying polarization (TE/TM), incidence angle, and fat thickness. Using a custom MATLAB pipeline combining multilayer…

This retrospective study evaluated liver lesion conspicuity during real-time MR-guided radiofrequency applicator placement using spoiled GRE and balanced SSFP MRI sequences in a 1.5 T scanner. Lesion detectability categories and contrast-to-noise ratio (CNR) were compared for hepatocellular carcinoma and liver…

This in vitro study examined 50 Hz ELF-EMF effects on human T-type calcium channels expressed in HEK293 cells and on native T-type channels in primary cultured mouse cortical neurons. The authors report that ELF-EMF (0.2 mT) inhibited Cav3.1, Cav3.2, and Cav3.3 channel activity without changing Cav3.2 expression or…

This engineering simulation study models colloidal particle transport and deposition in a membrane filtration channel at a particle volume fraction of 10%. The model couples a dynamically updating crossflow velocity field with particle-particle and particle-membrane interaction potentials (electrostatic double layer…

This animal PET study examined whether a weak 60-Hz magnetic field alters brain glucose utilization in rats. The abstract reports increased FDG uptake in hindbrain voxels when a 2.5-G field was oriented orthogonally to the sagittal plane, but not when field direction varied randomly. Distinct activation effects were…
Correction of main and transmit magnetic field (B0 and B1) inhomogeneity effects in multicomponent-driven equilibrium single-pulse observation of T1 and T2.

Jan 1, 2011
This methods paper addresses how B0 (main field) and B1 (transmit field) inhomogeneities can bias SPGR and bSSFP steady-state MRI signals used for multicomponent T1/T2 relaxometry and myelin water analysis. It describes using DESPOT1-HIFI to calibrate flip angles and adding a B0-related parameter with multiple…

Jan 1, 2009
This paper models biological proton pumping in cytochrome c oxidase under an applied oscillating electric field. The authors report that proton pumping efficiency and steady-state electronic currents vary significantly with the field’s frequency and amplitude. A spectral analysis is described as supporting dominant…
