This in vitro study tested whether a static magnetic field (SMF) could enhance the effects of cisplatin or adriamycin in Hepa1-6 tumor cells. The abstract reports that SMF combined with either drug increased growth inhibition and was associated with cell-cycle arrest, increased DNA damage, and more severe membrane…

This study evaluated magnetostimulation and magnetoledtherapy for pain reduction after dental implant treatment in three groups of 10 patients each. Pain was recorded using a VAS scale, and analgesic use was also tracked. The abstract reports lower pain scores and reduced analgesic use in the magnetostimulation…

This paper describes synthesis and characterization of magnetic nanoparticles intended for tumor hyperthermia applications. It reports that the particles show relatively high specific absorption rate (22–200 W/g) under a 160 kHz alternating magnetic field at 100–500 Oe, despite low saturation magnetization. The…

This cross-sectional study surveyed 883 HIV-infected patients on ART in Soweto, South Africa, to identify demographic correlates of using mobile phones as reminder tools. Older age, female gender, and lower education were associated with lower use of phones for clinic appointment reminders. Older age and lower income…

This animal experimental study examined combined exposure to potable mineral water and low-intensity ultrahigh-frequency electromagnetic radiation (~1000 MHz;

This engineering study examines composite optical dipole nano-antennas made of alternating silica and gold layers. It reports that a 50% filling factor yields a 2.0× increase in electric-field enhancement compared with a pure-gold antenna. The abstract frames the work in terms of photonics applications rather than…

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 study investigated pulsed electric field (PEF) pre-treatment of blueberries and its impact on juice production and recovery of bioactive compounds from press cake. PEF at 1–5 kV/cm (10 kJ/kg) increased juice yield and increased phenolics, anthocyanins, and antioxidant activity in juice compared with untreated…

This study evaluated whether fusing delayed enhancement MRI (DE-MRI) with magnetic resonance angiography (MRA) improves visualization of radiofrequency ablation lesions after pulmonary vein isolation. Eighteen atrial fibrillation ablation patients underwent both imaging approaches, and two observers scored lesion…

This animal study tested whether extremely low-level pulsed EMF (0.034 μG, 0.952 Hz) could suppress induced atrial fibrillation in 17 anesthetized dogs. EMF applied to cervical vagal trunks or across the chest was reported to suppress neural firing in the anterior right ganglionated plexi. The authors report that EMF…

This census-based cohort study in Switzerland examined modeled RF-EMF exposure from broadcast transmitters and childhood cancer risk using two cohort approaches. Across analyses, no association was reported for all cancers or childhood leukemia. Findings for CNS tumors were inconsistent, and the incidence density…

This open case study assessed transcranially applied pulsed electromagnetic fields (PEMF) as a potential therapy for multiple chemical sensitivity (MCS) in three patients. Two of three patients reported considerable improvements in MCS-related symptoms/functional impairments and reduced capsaicin-induced secondary…

This engineering paper describes a fiber-based method for stable radio-frequency dissemination using a hybrid frequency modulation approach. Two RF components are transmitted simultaneously using a single laser diode, with one component used for phase fluctuation detection and the other providing a compensated stable…

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 cross-sectional questionnaire study assessed how orthopaedic residents and consultants in Karachi used smartphones for clinical work and academics. Most respondents owned smartphones and reported using apps and internet/email, but fewer used them to share clinical data. The paper does not assess electromagnetic…

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 study describes the design, pilot testing, and validation of a mobile phone application version of the Guatemala NEMS-S supermarket survey. In a single supermarket, the app demonstrated high interrater reliability relative to the paper version and good test-retest reliability. The app also reduced survey…

This article describes a mobile phone-based pilot study in egocentric networks of 12 gay men and their peers (44 participants total). Participants completed daily mobile assessments of HIV-transmission and general health behaviors, and phone log data were collected from gay men with Android phones. The paper focuses…

This study develops and tests a theoretical model of how HeLa cells aggregate when exposed to a uniform AC electric field. Model-derived aggregation times and predicted string-length growth rates matched numerical simulation, and experiments observed substantial clustering in the chamber. The work is framed as…

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 assesses the risk of failure of composite high-voltage insulators in desert environments where sand accumulation and moisture can create conductive layers and leakage currents. Using realistic Sinai sand grain size and salinity data and an ABB composite insulator as a case study, the authors…
