[The morphofunctional cellular evaluation of liver and kidney in rats in dynamics of 6-month consumption of water produced with the use of noncontact activation after electrochemical treatment].

There were investigated morphofunctional indices of liver and kidney in male outbred rats in the dynamics of the 6-months consumption of water after its noncontact activation. There were studied 4 experimental groups of animals consumed waters named as "Anolyte" and in dependence on the activation time, 3 types of catholyte water ("Catholyte--5", "Catholyte--25", "Catholyte--40"). Moscow tap water settled for a week served as control.

[Study of cytogenetic and cytotoxic effect of non-contact electrochemically-activated waters in the five organs of rats].

For the first time the multiorgan karyological analysis of five organs of rats was applied for the study of the cytogenetic and cytotoxic action of the four types of non-contact electrochemically activated water in the 30-days in vivo experiment. The effects of investigated waters were not detected in bone marrow polychromatic erythrocytes. "Anolyte" (ORP = -362 mV) did not have a negative effect on rats.

Effect of some redox mediators on FAD fluorescence of glucose oxidase from Penicillium adametzii LF F-2044.1.

Glucose oxidase (GOx) of Penicillium adametzii LF F-2044.1 recovered by ultrafiltration, was characterized by spectrophotometric and spectrofluorometric methods. It was shown that spectra of GOx from P.

Comparison of glucose oxidases from Penicillium adametzii, Penicillium Funiculosum and Aspergillus Niger in the design of amperometric glucose biosensors.

The properties of amperometric glucose biosensors based on three different glucose oxidases and various redox mediators were evaluated. Glucose oxidases (GOx) from Penicillium adametzii, Penicillium funiculosum and Aspergillus niger and artificial redox mediators, such as ferrocene, ferrocenecarboxaldehyde, α-methylferrocene methanol and ferrocenecarboxylic acid, were used for modifying the graphite rod electrode and amperometrical reagent-less glucose detection. The obtained results were compared using N-methylphenazonium methyl sulphate in the solution.

[100 years of drinking water regulation. Retrospective review, current situation and prospects].

There is considered the history of the development of legislative requirements to the regulation of the quality of drinking water in different countries and international organizations during the period from 1912 to the present time. In terms of comparative analysis there is analyzed the current state of regulatory frameworks of the Russian Federation, WHO, EU, Finland, the UK, Singapore, Australia, Japan, China, Nigeria, the United States and Canada in the field of providing favorable conditions of population drinking water use. There has been noted the significant progress in standardization of the content of the biogenic elements and chemical pollution of drinking water in the absence of uniform requirements to the composition and properties of drinking water globally, that is bound to the need to take into account the national peculiarities of drinking water supply within the separate countries.
