Jan 1, 2025
This in vitro study reports that a static magnetic field (SMF) combined with paramagnetic calcium-polypyrrole nanoparticles (Ca-PPy) markedly increases bactericidal activity against E. coli and S. aureus. The authors attribute the enhanced killing to increased reactive oxygen species generation and associated…

Jan 1, 2022
This in vitro study developed magnetic electrospun nanofibers for bone regeneration and evaluated osteogenic and antibacterial properties. Functionalization with ATP and Mg increased mesenchymal stem cell adhesion, proliferation, and osteogenic marker readouts compared with unmodified fibers. The authors report that…

This study investigated how laboratory bacterial strains and skin bacterial isolates respond to static magnetic fields and radiofrequency EMF described as cell phone-level exposure. The authors report variable and inconsistent growth responses across species and across isolates from four subjects. They propose that…

Jan 1, 2017
This in vitro study tested 900-W microwave radiation regimens (3, 5, or 7 minutes) to disinfect type IV dental stone surfaces contaminated with S. aureus, E. coli, or C. albicans. The authors report that 5 and 7 minutes achieved sterilization for S. aureus, while 3 minutes did not fully sterilize; all times were…

Jan 1, 2015
This pilot-scale study evaluated pulsed electric field (PEF) processing of low-fat milk inoculated with E. coli, S. cerevisiae, or L. brevis. At 10 kV/cm and 200 kJ/L total pulse energy, the study reports multi-log microbial reductions, with >5-log reductions during storage at 200–250 kJ/L and slow regrowth over 15…

Jan 1, 2015
This in vitro study exposed five microorganisms (including indoor isolates and reference strains) to an extremely low frequency magnetic field (60 Hz, 3 mT) for two hours. The authors report a statistically significant increase in colony counts in exposed samples versus controls, with stronger stimulation in nutrient…
Non-linear adaptive phenomena which decrease the risk of infection after pre-exposure to radiofrequency radiation.

Jan 1, 2014
This animal study examined whether pre-exposure to radiofrequency radiation (from a GSM mobile phone) alters survival after subsequent Escherichia coli infection. The abstract reports higher survival in the group receiving both RF pre-exposure and bacterial challenge than in the group receiving only the bacterial…
Intestinal MMC-related electric fields and pancreatic juice control the adhesion of Gram-positive and Gram-negative bacteria to the gut epithelium--in vitro study.

Jan 1, 2008
This in vitro study tested whether a weak electric field reconstructed from duodenal spiking potentials during an MMC cycle affects bacterial adhesion to Caco-2 intestinal epithelial cells. The MMC-related electric field increased adhesion of Lactobacillus and Lactococcus strains, while two pathogenic strains…
