This plant study examined whether 2.45 GHz continuous-wave microwave exposure affects electric signaling in Nicotiana benthamiana after leaf burning. The authors report a significant reduction in the amplitude of the injury-evoked variation potential, mainly due to a reduced depolarization rate. The reported effect…

This in vitro study exposed human fetal and adult fibroblasts to 25 GHz microwave radiation and assessed multiple genotoxic and cellular endpoints. The authors report no evidence of direct DNA damage and no apoptosis or changes in prosurvival signalling proteins. However, they report increased total and…

This engineering/materials study tested how microwave heating power affects properties of ZnO nanoparticles produced by microwave solvothermal synthesis. Aggregate size reportedly varied (60–120 nm) with microwave power, while individual nanoparticle size and morphology remained constant (average 27 ± 3 nm) under the…

This paper reports the isolation of strain M26 from garden soil that was pre-treated with microwave radiation, followed by polyphasic taxonomic characterization. Based on morphological, chemotaxonomic, and 16S rRNA phylogenetic analyses, the authors propose the new species Streptosporangium minutum. The strain is…

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 experimental study examined electromagnetic radiation (EMR) emitted by coal rock with prefabricated cracks during mechanical loading. The authors report that intact rock EMR increased with loading, whereas cracked rock EMR showed staged and fluctuating behavior that became more pronounced as crack angle…

This review discusses the limited options for certain cancers and introduces non-ionizing electromagnetic fields as an emerging concept for cancer treatment. It summarizes the history of EMF use in medicine from the 1890s and describes novel methods aimed at targeting and treating cancer with non-ionizing radiation.…

This study assessed usability, feasibility, and validity of a smartphone-delivered virtual pedestrian environment by comparing it with a semi-immersive kiosk virtual environment. Among 68 adults, participants used the smartphone system without difficulty, reported no significant simulator sickness, and rated it as…

This level II diagnostic investigation evaluated whether vibrations generated by a mobile phone could screen for diabetic peripheral neuropathy. Among 61 participants across control, lower-limb injury, and neuropathy groups, the mobile phone vibration test showed higher reported overall accuracy than a tuning fork or…

This study compared patient-reported outcome (PRO) scores collected on paper versus automated mobile phone text messaging in orthopedic hand and upper extremity clinic patients. Over 48 hours, the same patients completed SF-12 and QuickDASH via text messages in random order. High intraclass correlations were reported…

This engineering/food-processing study evaluates pulsed electric field (PEF) treatment of fresh Artrhospira platensis biomass to enhance aqueous extraction of C-phycocyanin. Extraction depended on electric field strength, treatment time, and application temperature, with higher temperatures reducing the required…

This engineering study describes miniaturized, flexible, battery-free wearable pulse oximetry systems that use near-field communication (NFC) for wireless operation. The devices capture and transmit photoplethysmograms to derive blood oxygenation, heart rate, and heart rate variability. The abstract reports…

This article describes a signal-processing/measurement concept in pulsed magnetic resonance: achieving phase cycling through sinusoidal magnetic field modulation rather than changing pulse phases. The abstract states that modulation parameters can control spin precession phases, enabling separation of unwanted…

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 laboratory study assessed how pH, temperature, and pulsed electric fields (PEF) affect turbidity and protein aggregation in ovomucin-depleted egg white solutions. Heating to 60°C for 10 minutes produced marked aggregation at several pH levels, while PEF caused some aggregation only at pH 5 and 7 under the…

This modeling study examines how a noisy spiking neural network detects a weak applied electric field using an Izhikevich neuron framework with excitatory/inhibitory neurons and conduction delays. The authors report stochastic resonance driven by white noise that enhances detectability, and that this effect largely…
