The article presents results of studying the influence of linseed oil and drinking diet with a modified isotopic composition with low deuterium content on indicators of prooxidant-Antioxidant system during modeling of liver toxicity. The research was performed on 36 rabbits (weighing 3.1-3.5 kg) which were divided into 4 groups. Croup 1 consisted of control animals; in group 2, 3 and 4 in rabbits the liver toxicity was modeled by administration of CCl4 (intraperitoneally, in the form of a 50% oil solution, 1 ml per kg bw, 2 times a week for 30 days); nutritional correction using flaxseed oil (0.1 ml per 100 gbw) and drinking diet with deuterium depleted water (50 ppm) was carried out in animals from groups 3 and 4 respectively, for 30 days prior to simulation of toxic hepatitis and more throughout the experiment. Using the method of nuclear magnetic resonance and mass spectrometry the influence of deuterium depleted water on D/H composition of the blood plasma, bile and liver tissues was determined: The deuterium concentration in these biological materials significant decreased. The most significant decrease in the deuterium content (30.2% compared with the control group) was found in blood plasma in animals from group 4. The study of the state of prooxidant-Antioxidant balance of the liver and bile showed oxidative stress at the local level, with the toxic effects of carbon tetrachloride. This was followed by EPR spectroscopy data pronounced increase of the number of paramagnetic centers in the hepatocytes by 5.4, 1.9 and 2.8 fold in animals of 2, 3 and 4 groups, respectively (compared to the indicators of the first group). There was also increase in the intensity of free radical oxidation processes in the bile with a simultaneous reduction of its antioxidant activity, which was significantly less distinct (on average 51.18-59.8%, p<0.05) in animals treated with nutritional correction, indicating that higher functional activity of protective systems involved in recycling prooxidant factors using dietary lipophilic antioxidants and water with low deuterium content. Overall, the results of the present study indicate that existing in the liver and bile autonomous mechanisms of regulation of the state of prooxidant-Antioxidant systems are quite sensitive to the effects of antioxidant factors of lipophilic nature and shifts of isotopic D/II gradient, and suggest usefulness of the products that can affect these indicators to increase adaptive capabilities of the organism during intoxication.

Effect of molasses, a waste formed in manufacture of sugar, on the gypsum setting time was studied. It is shown that molasses solutions can be used to control the hardening time of the gypsum paste. © 2013 Pleiades Publishing, Ltd.

Diazotation of substituted 3-aminopyridines with subsequent substitution of diazo groups with sulfonyl groups in the obtained diazonium chlorides was used to synthesize the corresponding pyridine-3-sulfonyl chlorides. The conditions for this synthesis were optimized by taking into account the detailed understanding of this substitution. The synthesized pyridine-3-sulfonyl chlorides were converted to pyridine-3-sulfonic acids and -sulfonyl amides. © 2014 Springer Science+Business Media New York.

Ecological inefficiency of conventional IPM programs for apple orchard protection in the North Caucasus results from arbitrary use of compounds producing opposite ecological effects, i.e., broad-spectrum chemical insecticides after environment-friendly selective ones, which destroys the apple orchard agroecosystem. The investigation was aimed at developing an effective and ecologically acceptable program with alternation of environment-friendly compounds which act along the same vector to preserve the populations of natural enemies of the pests and thus to stabilize the apple orchard agroecosystem, i.e., create an ecological type of orchard. In this kind of orchards, broad-spectrum chemical pesticides are prohibited whereas selective biological compounds (including synthetic ones) and methods are welcomed. The test runs of the resulting pest and enemy management (PEM) programs based both on bioregulators (Insegar, Match, Dimilin) and bio-insecticides (Phytoverm™, Lepidocid™, etc.) in 2007 and 2009 demonstrated their high efficiency: the apple fruit damage by codling moth was 1.2% and 0.3%, respectively. The test of sticky bands fixed on apple tree trunks to prevent ants from getting to the crowns showed a significant increase in the abundance of predaceous bugs which sharply reduced the green apple aphid population. © 2010 Pleiades Publishing, Ltd.

Triaxial tests are often used, along with other research methods, in order to define parameters of geotechnical data. The main topic being conferred in work is analysis of influence, exerted by stamp and latex shell, upon the results of triaxial machine soil tasting. The stabilometer modeling and verification was produced. Calibration of soil model parameters, derived from triaxial tests, is brought in work. The necessity of three dimensional simulation of soil testing process is pointed out in order to take into account stamp and shell influence. © 2011, International Journal of GEOMATE.
