This in vitro study used a scratch wound model in human immortalized keratinocytes (HaCaT) to examine effects of extremely low-frequency electromagnetic fields (ELF-EMF). ELF-EMF exposure was reported to accelerate wound closure compared with sham and to increase inflammatory cytokine expression/release. The authors…

This study reports synthesizing hydroxyapatite and carbonate-substituted hydroxyapatite using ultrasound and microwave radiation as processing methods. The authors report that these physical factors produced calcium-deficient hydroxyapatite and B-type carbonated apatite and increased in vitro bioactivity compared…

This engineering study describes synthesis of nano-metal binary oxide catalysts using complexation and impregnation with ultrasonic intervention for low-temperature catalytic oxidation of toluene under microwave radiation. The La-Co catalyst prepared with ultrasonic intervention is reported to have the best…

This in vitro study describes microwave-assisted, green-chemistry synthesis of pH-sensitive chitosan beads crosslinked with a glutamic acid/1,5-pentanodiol mixture and optionally modified with Tilia platyphyllos extract. The beads were characterized (FT-IR, SEM), tested for swelling, pH sensitivity, antioxidant…

This in vitro study compared ginsenosides extracted using pulsed electric field (PEF) versus solvent cold soak extraction (SCSE). The abstract reports that PEF extracts had higher antioxidant capacity and provided greater protection against hydrogen peroxide-induced oxidative stress in HEK-293 cells, including…

This study compared thermosonication, pulsed electric field, and thermal processing for preserving Royal Gala apple juice and evaluated sensory attributes and quality stability during 30 days of storage at 3°C and 20°C. Thermosonication and pulsed electric field produced juices with different taste compared with…

This in vitro study exposed human keratinocyte cells (NCTC 2544) to 50 Hz ELF-EMF at 0.25–2 G and assessed oxidative stress-related endpoints. Significant increases in ROS were reported at 0.5 and 1 G, with associated short-term changes in antioxidant and lipid peroxidation markers. The authors report that…

This clinical study evaluated whether adding ELF-EMF exposure to a 4-week rehabilitation program affects antioxidant and clinical status in ischemic stroke patients. Fifty-seven patients were assigned to an ELF-EMF group or a non-ELF-EMF group, with the exposed group receiving 40 Hz, 7 mT for 15 minutes per day over…

This in vitro study examined rat adipose-derived mesenchymal stem cells exposed to zinc sulphate in the presence of an ELF electromagnetic field (50 Hz, 20 mT). The authors report increased osteogenic differentiation markers (gene expression, ALP activity, and calcium levels) under combined ZnSO4+EMF conditions,…

This animal experimental study reports that low-intensity ultrahigh-frequency electromagnetic radiation and a low-intensity low-frequency magnetic field, applied after radiation exposure, enhanced metabolic and regenerative processes in rat testes and liver. The magnetic field was associated with increased…

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 in vitro study exposed rat calvarial osteoblasts to 50 Hz, 0.6 mT pulsed electromagnetic fields for 1.5 hours and measured early differentiation-related markers over 0–12 hours. The abstract reports increased ALP activity at 3 hours and time-dependent changes in ALP, Runx2, and OSX transcription and Runx2/OSX…

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 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 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 gamma radiation and static magnetic field treatments on soybean seeds stored for six months and then subjected to accelerated ageing. The authors report that certain gamma doses (3–5 kGy) and magnetic field strengths (100–200 mT) helped maintain seed protein/oil characteristics and antioxidant…

This laboratory study evaluated how pulsed electric field (PEF) processing affects antioxidant activity and structure of 10–30 kDa corn peptides. Antioxidant activity was assessed via DPPH inhibition and optimized using response surface methodology. Under reported optimal conditions (10 mg/mL, 15 kV/cm, 2,000 Hz),…
