“…The significance is greater due to the use of different electrical devices in everyday life and modern medicine. Moderateintensity magnetic fields (1 mT -1 T) can influence the activity of some ion channels in cell membranes but the mechanisms of actions still remain unknown (Tolosa et al 2011). Low frequency magnetic fields appear to increase charge movements within membrane protein, while electric fields during normal condition inhibited Na + /K + pump activity (Blank 1995(Blank , 2005.…”

Abstract. Aim of this study was to investigate the application of normalized mean of the empirical Higuchi fractal dimension (FD) distributions, as a new approach to analyze the spontaneous bioelectrical activity of garden snail (Helix pomatia) Br neuron. The effect of ouabain on modulation of Br neuron bursting activity before and after the exposure to 10 mT static magnetic field (SMF) was observed by analyzing the following parameters: action potential (AP), interspike interval (ISI) and interbursting interval (IBI) components. Normalized mean of the empirical FD distributions were formed for the following experimental conditions: Control 1, Ouabain 1, Control 2, SMF 2, ASMF 2, Control 3, SMF 3 and Ouabain ASMF 3. Our main results have shown that ouabain without SMF induced increase in participation of AP and a decrease in participation of IBI components compared to the first control condition. However, in the presence of 10 mT SMF, ouabain-induced changes of measured parameters of Br neuron activity were less pronounced compared to the third control condition. We have shown that normalized mean of the empirical FD distributions is a useful method for detecting the changes in AP, ISI, and IBI components of complex bursting activity in altered physiological states.

“…Wang, et al [93] results showed that 1.00 T and 1.13 T SMFs could increase cellular adenosine triphosphate (ATP). The biological effects of other SMFs(except for GMF and a HMF) were shown in Novitskii, et al [17]; Sullivan, et al [18]; Tolosa, et al [19]; Martino [20].…”

More recent concerns have been raised about the biological effects of all different weak magnetic fields (MFs) with the development of electric device era and information era. The biological effects due to weak MFs just like a hypomagnetic field (HMF) or near-null magnetic field is a very important subject for aerospace traveling and space station living. A large number of studies on the biological effects of other weak MFs have been carried out. The biological effects of different weak MFs can be negative or positive. Many mechanisms to explain the bioeffects of weak MFs have been given. Are there possible common mechanisms of the different biological effects in different weak MFs ? It's unbelievable and sound impossible at first sight that different bioeffects of different weak MFs have common mechanisms. But possible common mechanisms can exist. In this study, the author proposes the relations between the singlet yield of the radical pair and the weak MFs are the possible common mechanisms. Giving one possible common mechanism of bioeffects of all different weak MFs including impulsed ones is the first to the author's known. Here, the weak MFs are ones that cannot produce thermal bioeffects not only limited below 1mT.
