“…Thus, the obtained data demonstrate pronounced geroprotective DDW effect associated with DDW antistress action which has manifested in formation of stable GNAR of the calm and elevated activation, contributing to a considerable increase in nonspecific resistance and initiation of the restoration process in the aging female rats. It is obvious that the said effects take place due to such a specific property of DDW as its capability to activate the cell metabolism and elevate excitability of the neuroendocrine regulation centers [13,14]. The data on the development of GNAR of the calm and increased activation under the DDW influence are in good agreement with the known findings in favor of the activating effect made by DDW on the CNS serotonergic structures [25], since the relationship between the given GNAR development and an increase in serotonin concentration in brain structures and blood formed elements had been established earlier [5].…”

BackgroundThe anomalous properties of water have been of great interest for generations of scientists. However the impact of small amount of deuterium content which is always present in water has never been explored before. For the first time the fundamental properties of deuterium depleted (light) water at 4°C and 20°C are here presented.ResultsThe obtained results show the important role of the deuterium in the properties of bulk water. At 4°C the lowest value of the kinematic viscosity (1.46 mm2/s) has been found for 96.5 ppm D/H ratio. The significant deviation in surface tension values has been observed in deuterium depleted water samples at the both temperature regimes. The experimental data provides direct evidence that density, surface tension and viscosity anomalies of water are caused by the presence of variable concentration of deuterium which leads to the formation of water clusters of different size and quantity.ConclusionsThe investigated properties of light water reveal the origin of the water anomalies. The new theoretical model of cluster formation with account of isotope effect is proposed.

“…Over the last decades the investigation of this object continues to expand introducing corrections to results obtained earlier and supplementing by new data of water properties [2][3][4][5][6][7][8][9][10]. Invariably basic is such physical indicator as freezing temperature of normal and heavy waters.…”

Using the method of cryoscopy we determined the freezing temperature of light water with D/H= 4.2 ppm, 18 O/ 16 O = 910 ppm. It was found that light water freezes at the above zero temperature (0.3 ± 0.1°C) irrespective of cooling rate. It is shown that light water begins to freeze only at an overcooled metastable state. Under conditions of experiment the nucleation and growth of dendrite crystals of ice depends on the cooling rate and starts at the temperature -5.3; -8.8; -9.8 ± 0.1°C at the average cooling rate respectively 0.2; 0.3; 0.5°C⋅min -1 . It is shown than in usual water the growth of dendrite ice crystals starts at minus temperature (-6.4;-7.5; -8.8 ± 0.1°C) and increases with an increase of the average cool ing rate respectively from 0.2 to 0.6°C⋅min -1 . It was found that the initial freezing temperature of heavy water constituted -3.0--4.0 ± 0.1° at the rate of its cooling 0.2-1.0°C⋅min -1 . However in this case the freezing temperature of normal and heavy waters does not depend on the cooling rate and freezing of nor mal and heavy waters and according to reference data constitutes respectively 0.1 ± 0.1 and 3.9 ± 0.1°C.
