Impact of various electromagnetic fields on the transdermal permeability of naproxen and the effect of active compound exposure on magnetic field properties.

This ex vivo study tested whether different magnetic-field modalities change transdermal delivery of naproxen through pigskin. Rotating magnetic fields (RMF) at 50 Hz produced the greatest increase in permeation metrics versus a no-EMF control, while negatively polarized static fields reduced permeation.…

C-phycocyanin extraction assisted by pulsed electric field from Artrosphira platensis.

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…

Correction of microcirculatory disturbances with terahertz electromagnetic radiation at nitric oxide frequencies in albino rats under conditions of acute stress.

This animal study reports that terahertz electromagnetic irradiation at nitric oxide (NO)-related frequencies (150.176150.664 GHz) corrected peripheral microcirculatory disturbances in albino rats experiencing acute immobilization stress. The abstract frames the effect as a correction of stress-related peripheral…

Ohmic heating of peaches in the wide range of frequencies (50 Hz to 1 MHz).

This engineering/food science study examined ohmic heating of peaches at 60 V/cm using bipolar pulses across frequencies from 50 Hz to 1 MHz. Heating time to a target temperature and multiple electrical properties were frequency-dependent, particularly for intact tissue. The authors report faster electro-thermal…
