“…Our results agree with previous findings that short-term powerfrequency magnetic field exposure causes an increase in the body mass of mice and cattle [1][2][3][4]18]. Electrical fields alone did not produce any change in the body mass of pregnant lactating cows relative to unexposed controls [19], whereas magnetic fields did [2].…”

“…There is some evidence that exposure of various animals, including mice and cattle, to a power-frequency magnetic field can increase body mass relative to unexposed controls [1][2][3][4]. This is a potentially interesting finding because the strength of the Earth's magnetic fields varies depending on latitude, and has varied over evolutionary time.…”

Abstract-There is some evidence that exposure of various animals to a power-frequency magnetic field can cause increases in body mass. However, the precise nature of the relationship is not clear, particularly for long-term exposure. To clarify the relationship between long-term power-frequency magnetic field exposure (2 years) and animal body mass, we conducted a pooled analysis of data in two studies to examine the impact of power-frequency magnetic field exposure on body mass as compared with sham-exposed rats of both sexes. Relative body mass was the response variable, and the study duration (in weeks), magnetic flux density (µT), and daily exposure time (hours/day) were the explanatory variables with adjustment for the study. We analyzed by sex. The P -value (P ) was defined as the probability of having observed our data (or more extreme data) when the null hypothesis was true. In multiple linear regression analyses of male and female rats, performed separately, we obtained estimates of the effect on relative body mass of study duration (coefficients 0.0225 and 0.0201, respectively; both P < 0.0001), magnetic flux density (coefficient 0.0002 for males, P < 0.0001; coefficient −0.0002 for females, P = 0.0015), and daily exposure time (coefficient 0.046 for

“…As noted above, this dependence is actually observed: inhibition of tissue metabolism due to hypoxia during cardiac arrest was accompanied by drop in the electric field strength. This relationship is confirmed in experiments on animals [21]. For example, in rats inhibition of metabolism of the tissue due to cardiac arrest (death of the animal) or by general anesthesia is accompanied by a significant drop in the electric field strength [22].…”

This paper presents the results of evaluation of possible biophysical methods and approaches for registering of various non-ionizing radiation (NIR) wave types of the human body in the optic and electromagnetic range. Various types of NIR (electromagnetic waves, infrared radiation, thermo radiation, bioluminiscence) emitted from the human body were reviewed. In particular the results on of spontaneous biophoton emission and delayed luminescence from the human body are submitted along with infrared thermography (IRT) results. It was shown that 1 cm 2 of skin generally emits 85 photons for 1 s. The intensity of biophoton emission ranges from 10 −19 to 10 −16 W/cm 2 (approx. 1-1000 photons . cm -2. s -1 ). The specific photon emission from part of the human thumb was detected as a spectrum of various colours with the method of Colour coronal spectral analysis on a device with an electrode made of polyethylene terephthalate (PET hostaphan) with applied electric voltage 15 kV, electric impulse duration 10 s, and electric current frequency 15 kHz. It was established that photons corresponding to a red color emission of visible electromagnetic spectrum have energy at 1,82 еV. The orange color of visible electromagnetic spectrum has energy at 2,05 eV, yellow -2,14 eV, blue-green (cyan) -2,43 eV, blue -2,64 eV, and European Reviews of Chemical Research, 2015, Vol.(3), Is. 1 5 violet -3,03 eV. The reliable result measurement norm was at E ≥ 2,53 eV, while the spectral range of the emission was within  = 380-495±5 nm and  = 570-750±5 nm. Also were estimated some important physical characteristics (energy of hydrogen bonds, wetting angle, surface tension) of water by the methods of non-equilibrium energy (NES) and differential non-equilibrium energy (DNES) spectrum of water, that helps understand in general how electromagnetic radiation interacts with water and establish the structural characteristics of water.
