This laboratory/analytical study examined how sample matrix affects sample sweeping in micellar electrokinetic chromatography under an inhomogeneous electric field. It reports strong focusing for hydrophobic cationic analytes when the sample matrix conductivity is much higher than the BGE, even with low surfactant…

This engineering study evaluates how anatomical/geometric differences affect MRI RF safety metrics. Simulations and a bovine-phantom experiment found that similar transmit B-field patterns can coincide with notably different peak SAR and temperature rise. The authors highlight challenges in using…

This mouse study examined chronic smartphone electromagnetic radiation exposure and its effects on spatial working memory and hippocampal progenitor cell proliferation. The authors report no significant differences in Y-maze spontaneous alternation or BrdU-labeled progenitor proliferation after exposure, but…

This engineering paper presents an experimentally validated wearable personal exposimeter system for RF-EMF exposure monitoring, motivated by increasing wireless applications. It uses a distributed measurement approach and integrates inertial sensors to capture activity and posture during measurements. The system is…

This proof-of-concept cohort study evaluated cardiac magnetic resonance (CMR) radiofrequency tissue tagging to diagnose constrictive pericarditis and compared results with surgical findings and cardiac catheterization. In 16 patients who underwent pericardiectomy, CMR positivity agreed 100% with intraoperative…

This retrospective study evaluated patient satisfaction and pain relief after pulsed radiofrequency treatment of the sphenopalatine ganglion for chronic facial and head pain. The abstract reports complete pain relief in 35% of patients, mild to moderate relief in 42%, and no acceptable relief in 23%. The authors…

This exposure-assessment study compared modeled at-home RF-EMF from mobile phone base stations (NISMap) with 24-hour personal measurements in 93 Dutch participants. Correlations were low to moderate, with better agreement for time spent at home than for the full 24-hour period. While modeled estimates could rank…

This animal study exposed developing Sprague Dawley rats to 2.14 GHz W-CDMA RF-EMF at a whole-body SAR of 0.2 W/kg for 9 weeks (20 h/day). No differences were reported in multiple T cell population measures across blood, spleen, and thymus. Some Th1/Th2-related genes were upregulated (notably in thymus), but serum…

This observational space-physics study reports a substorm-associated injection of MeV electrons into the inner magnetosphere measured by Van Allen Probes-A. A strong dipolarization electric field (~50 mV/m) coincided with a dispersionless injection up to ~3 MeV and pitch angle signatures consistent with betatron…

This animal organ-preservation study compared 12-hour porcine heart preservation at -3°C using a device generating a variable magnetic field versus conventional 4°C preservation. The subzero variable-magnetic-field condition showed higher myocardial ATP, lower lactate, and less mitochondrial ultrastructural damage…

This animal/model-organism study examined whether weak low-frequency magnetic fields tuned to a proposed parametric resonance for calcium ions affect Ca(2+)-dependent proteolysis. It reports time-dependent modulation of Ca(2+)-dependent proteinase activity in fish and whelk and states that a minimal exposure time for…

This cross-sectional study developed and validated a Persian version of the Test of Mobile Phone Dependency (TMD) in 350 Tehran university students. Factor analysis identified three factors and the scale showed high internal consistency and moderate test-retest reliability. The authors report a best cut-off point of…

This Data in Brief article provides additional experimental data supporting a related study on mitigating ageing effects (Staebler-Wronski effect) in hydrogenated amorphous silicon solar cells. The associated method involves applying reverse bias stress and evaluating how temperature, electric field intensity,…
