Low intensity magnetic fields stimulate the electron transport …
Recent studies suggested that low intensity magnetic fields (MF) exerted a stimulatory effect on the mitochondrial metabolic activity, when applied to the whole animals, organs, or single cells. However, the mechanisms and the ranges of MF strength for this stimulation are still unclear. Here we hypothesize that static low intensity MF can …Web
