“…Our results suggest that the magnetic field reduced the cell damage induced by low temperatures. Recently, it was reported that either by direct effect on paramagnetic ROS (reactive oxygen species) or indirect changes to signaling pathways the magnetic field might affect the oxidative stress of reperfusion injury [16]. Moreover, electron paramagnetic resonance provides a non-invasive way to assay ROS build up during preservation if titration or the like are unappealing [17].…”

Under subzero degree conditions, free water contained in biological cells tends to freeze and then most living things die due to low temperatures. We examined the effect of a variable magnetic field on Drosophila under supercooled conditions (a state in which freezing is not caused even below the freezing point). Under such supercooled conditions with the magnetic field at 0°C for 72 hours, −4°C for 24 hours and −8°C for 1 hour, the Drosophila all survived, while all conversely died under the supercooled conditions without the magnetic field. This result indicates a possibility that the magnetic field can reduce cell damage caused due to low temperatures in living things.

“…The magnetic field not only inhibits the movement of water molecules but also has been reported to decrease the generation of reactive oxygen species and reduce the cellular damage. 27 Moreover, the magnetic field also has the potential to realize long-term freezing preservation of the heart. At temperatures below −60°C, metabolism in the cells is totally suppressed.…”

“…On the other hand, Lednev’s model suggests the maximum biological effects of an alternating magnetic field with an intensity that exceeds that of the static magnetic field by approximately 1.8 times [ 11 ]. The effectiveness of this Hac/Hdc ratio has more experimental confirmations that were performed mainly using the organisms but not cell cultures as exposed objects [ 9 , 13 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. Probably, the above-described effects of alternating magnetic fields with different intensities of 0.9 and 1.8 Hac/Hdc regarding Blanchard-Blackman and Lednev’s models [ 11 , 12 ] might be due to the specificity of cells and organisms as objects with different levels of biological organization.…”

A biophysical model for calculating the effective parameters of low-frequency magnetic fields was developed by Lednev based on summarized empirical data. According to this model, calcium ions as enzyme cofactors can be the primary target of low-frequency magnetic fields with different parameters tuned to calcium resonance. However, the effects of calcium-resonant combinations of static and alternating magnetic fields that correspond to Lednev’s model and differ by order in frequency and intensity were not studied. It does not allow for confidently discussing the primary targets of low-frequency magnetic fields in terms of the magnetic influence on ions-enzyme cofactors. To clarify this issue, we examined the response of freshwater crustaceans Daphnia magna to the impact of combinations of magnetic fields targeted to calcium ions in enzymes according to Lednev’s model that differ in order of magnitude. Life-history traits and biochemical parameters were evaluated. Exposure of daphnids to both combinations of magnetic fields led to a long-term delay of the first brood release, an increase in the brood size, a decrease in the number of broods, and the period between broods. The amylolytic activity, proteolytic activity, and sucrase activity significantly decreased in whole-body homogenates of crustaceans in response to both combinations of magnetic fields. The similarity in the sets of revealed effects assumes that different magnetic fields tuned to calcium ions in biomolecules can affect the same primary molecular target. The results suggest that the low-frequency magnetic fields with parameters corresponding to Lednev’s model of interaction between biological molecules and ions can remain effective with a significant decrease in the static magnetic background.
