This animal study tested four frequency-band EMF exposures (1–50,000 Hz variants) in an ovariectomized mouse model of osteoporosis over 8 weeks (3 h/day). Low- and band-pass exposures increased bone formation markers and osteogenesis-related gene expression, while high-pass exposure decreased both formation and…

This in vitro materials study compares microwave irradiation versus conventional water-bath heating for synthesizing HPMC-graft-(PVA-co-acrylic acid) hydrogels loaded with captopril. The authors report that microwave-synthesized hydrogels had more uniformly porous structures and higher swelling ratios, with…

This case report describes a paediatric burn injury resulting from a mobile phone lithium-ion battery explosion. The patient was treated with selective enzymatic debridement, which the authors note is simple, minimally invasive, and safe. The report concerns an acute thermal injury mechanism rather than EMF exposure.

This engineering paper reports a prototype wearable patient-monitoring device that transmits vital-sign measurements via Bluetooth LE during MRI. Across 7 MRI acquisitions (25 minutes total), the authors report no Bluetooth packet loss, increased PPG noise during MRI, and no effect on temperature/humidity readings.…

This engineering study uses a 3D electromagnetic solver to simulate in-to-out body RF path loss for a wireless capsule endoscopy link. The capsule antenna is tuned for the 402 MHz MICS band while accounting for human body properties. The authors examine how capsule misalignment, rotation, and the human body model…

This engineering study addresses inter-cell interference in LTE networks as a driver of packet loss between base stations and mobile stations. It examines Soft Frequency Reuse (SFR) and implements a new hybrid frequency reuse method with greater total system bandwidth than SFR while keeping per-cell bandwidth the…

This engineering/food science study measured dielectric constant (ε'), dielectric loss factor (ε″), and power penetration depth in beef and gravy preparations across 27–1,800 MHz and 20–130 °C. The dielectric properties generally decreased with increasing frequency, and penetration depth decreased with increasing…

This laboratory study investigates various ionic liquids using an electrophoresis of a charged droplet method in a dielectric liquid under an applied electric field. While charged droplets typically bounce between electrodes, the authors report that some ionic liquids exhibit a retreating behavior. They interpret…

This engineering study assesses optimal RF frequencies for wireless communication with intraoral electronic devices using an intraoral tongue drive system as an example. It compares 27 MHz, 433.9 MHz, and 2.48 GHz based on path loss, radiation patterns, and bit error rate tests, with adaptive impedance matching…

This engineering study reports optical and electrical characteristics of photonic gel cells made from a PS-b-P2VP lamellar film and a hydrogel electrolyte on ITO glass. Applying 2 V between two facing electrodes over 30 minutes shifted the device reflectance peak from 538 nm up to 604 nm with limited bandwidth…

This single-institution cohort compared radiofrequency-assisted laparoscopic liver resection with open resection over 5 years (47 vs 87 patients). Laparoscopy was associated with lower blood loss and similar 5-year overall and disease-free survival compared with open surgery. The authors conclude the laparoscopic…

This engineering study reports theoretical analysis and experimental demonstration of an S-tapered optical microfiber integrated with ferrofluid for magnetic-field tunability. The transmission spectrum and dip wavelengths were found to vary with magnetic-field intensity, with a Langevin-like response and a linear…

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 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 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 study evaluated MRI safety parameters for three commercial veterinary RFID microchips at 1 T, assessing movement forces, heating, artifacts, and device function. Translation and torque were reported to be larger than expected from normal activity, but no significant heating was observed and microchip function…

This study compared slow conventional air defrosting with fast radio frequency (RF) defrosting/tempering in lean beef (whole, minced, and comminuted) using drip loss, NMR relaxometry, and dielectric spectroscopy. RF thawing was associated with lower drip loss and lower micronutrient loss in drip than air thawing,…

This experimental animal study compared tympanic membrane closure time after myringotomy performed by microknife versus radiofrequency microcautery, with and without mitomycin C. Radiofrequency myringotomy differed significantly from knife myringotomy, and the 0.7 mm radiofrequency tip combined with mitomycin C was…

This study measured dielectric properties of beef Semitendinosus across 27, 915, and 1800 MHz and temperatures from -5 to 130 °C using an open-ended coaxial probe. The results indicate that frequency, temperature, and muscle fiber orientation influence dielectric constant, dielectric loss, and calculated penetration…

This engineering study reports using radio-frequency (RF)-based dielectric heating to assist NaOH pretreatment of switchgrass to improve enzymatic digestibility. Under the stated conditions, RF-assisted pretreatment produced higher xylose and glucose yields than conventional heating and maintained higher yields at…
