This in vitro FTIR study examined human haemoglobin aqueous solutions exposed to a 200 mT static magnetic field for 3 and 7 hours, with and without the disaccharides sucrose and trehalose. The authors report spectral changes (amide A decrease and reduced CH(3) stretching) in haemoglobin dissolved in bi-distilled…

This in vitro study examined how an externally applied electric field influences the self-assembly of oppositely charged molecules in water into an ordered membrane. The authors report that electric fields changed the kinetics of membrane formation and altered membrane thickness, nanofiber growth orientation, and…

This randomized, placebo-controlled, double-blind, cross-over trial evaluated a wrist-applied PEMF bracelet in 18 migraine patients and examined possible modulation of placebo effects. In the overall group, both PEMF and placebo were associated with similar reductions in migraine frequency and intensity. The authors…

This study investigates instrumentation and procedures to assess electromagnetic exposure from compact fluorescent lamps (CFLs) by measuring both incident and induced fields in the 10 kHz–1 MHz range. For some CFLs, incident electric fields exceeded ICNIRP reference levels at close distances, but induced fields were…

This study reports an aqueous two-phase extraction method for equine spleen ferritin using polyethylene glycol (PEG) and hydroxyethyl starch (HES). Ferritin partitioning depended on PEG/HES concentrations and PEG molecular weight, and applying a magnetic field increased ferritin accumulation in the PEG-rich phase…

This experimental and clinical study compared two umbrella-shaped expandable radiofrequency ablation electrodes (SuperSlim vs CoAccess) across different ablation algorithms. In ex vivo bovine liver, CoAccess generally produced larger ablation areas and required longer ablation times than SuperSlim, with no…

This paper reports molecular dynamics simulations of polyelectrolyte brushes subjected to external electric fields, focusing on how chain stiffness and salt concentration affect responses. The simulations suggest higher salt concentrations strengthen an induced opposing field from ion redistribution, which resists…

This animal study reports that terahertz electromagnetic irradiation at nitric oxide (NO)-related frequencies (150.176150.664 GHz) corrected peripheral microcirculatory disturbances in albino rats experiencing acute immobilization stress. The abstract frames the effect as a correction of stress-related peripheral…

This study evaluated pulsed electric fields (PEF) as a pasteurization method for raw skim and whole milk across multiple treatment intensities and storage conditions. The abstract reports only minor changes in physicochemical properties and small decreases in some composition measures under stronger treatments.…

This paper describes the design and preliminary implementation of a mobile-phone-based wireless blood pressure monitoring system that transmits data via Bluetooth and computes blood pressure and heart rate on the phone. The authors state that experiments demonstrated the device’s reliability and stability, and that…

This retrospective cross-sectional study evaluated pulsed radiofrequency (PRF) for chronic pain in patients who did not respond to conventional treatment. Across 24 patients treated at different anatomical regions, 66.7% reportedly achieved at least a 50% reduction in VAS pain scores over a mean follow-up of 8.5…

This paper addresses heat dissipation mechanisms of magnetic nanoparticles used in targeted hyperthermia under large alternating magnetic fields. Using numerical comparisons, it reports additional features in relaxation loss for rotatable superparamagnetic nanoparticles and field-induced formation of oriented…

This engineering paper describes low-power wireless sensor nodes and a cluster-based dynamic-tree hierarchical WSN architecture for monitoring historical buildings and wooden artifacts for early pest detection. The authors report simulation and demonstration results indicating improved scalability and reliability…

This engineering study describes an experimental setup using a small electret condenser microphone connected to a notebook/PC to detect extremely low frequency signals. Using a small air cell made from a drilled DVD plate with a speaker and microphone on opposite sides, the microphone captured signals in the 0.5–20…

This university-based pilot study evaluated whether two-way SMS text messaging could be used to collect situational assessment data during simulated public health critical events. Among 63 enrolled students, 76.7% of prompted SMS surveys were completed, and most responses were returned quickly. The authors conclude…
