External low energy electromagnetic fields affect heart dynamics: surrogate for system synchronization, chaos control and cancer patient's health.

This paper discusses how low-energy, specifically modulated electromagnetic fields delivered via an active closed-loop medical device may temporarily alter plasma membrane ionic flow and heart oscillation dynamics. It frames heart rate dynamics as a surrogate for systemic synchronization/entrainment and suggests…

Mg.ATP-decorated ultrafine magnetic nanofibers: A bone scaffold with high osteogenic and antibacterial properties in the presence of an electromagnetic field.

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…

[Modulating effect of weak combined magnetic fields on duration of mealworm beetle Tenebrio molitor metamorphosis stage].

This animal study reports that combined static (42 μT) and very weak alternating (250 nT) magnetic fields can modulate the duration of metamorphosis in Tenebrio molitor pupae depending on the alternating-field frequency. A shorter pupal stage was reported at 4.4 Hz, an inhibiting effect at 32.2 Hz, and no noticeable…

Nanosecond pulse electric field activation of platelet-rich plasma reduces myocardial infarct size and improves left ventricular mechanical function in the rabbit heart.

This animal and in vitro study evaluated nanosecond pulsed electric fields (nsPEF) as a nonchemical method to activate platelet-rich plasma (PRP) for cardioprotection. In rabbits undergoing brief coronary occlusion followed by reperfusion, PRP injection into ischemic myocardium was associated with reduced infarct…
