[Nutrition of pregnant. Comparative analysis based on data from a survey of residents of Russian Federation and the Republic of Azerbaijan (on the example of Astrakhan and Baku)].

Poor nutrition of the expectant mother leads to an unfavorable course of pregnancy and a number of serious deviations in the development of the child. Therefore, a multifaceted study of the actual nutrition of a pregnant woman is relevant, including the identification of trends associated with geographical, ethnic, and family characteristics. The study was aimed at conducting a comparative analysis of the nutrition of pregnant women from two cities, Astrakhan (Russian Federation) and Baku (Republic of Azerbaijan), by means of a questionnaire.

[The effectiveness comparison of various conservative treatment options of nasopharyngeal inflammation in children].

Unlabelled: The problem of hyperplasia/inflammation of the structures of the Pirogov-Waldeyer lymphoid-pharyngeal ring and related complications is one of the most frequently discussed in pediatric practice, in particular in matters of methods and expediency of conservative treatment. The article describes the effectiveness of various regiment of conservative treatment of pediatric patients with inflammation of the pharyngeal tonsil (adenoiditis) based on the results of an open comparative observational study.

Objective: To compare the effectiveness of various schemes of conservative therapy of adenoiditis in children.

Improving the Durability of Lime Finishing Mortars by Modifying Them with Silicic Acid Sol.

Lime materials are in great demand for the restoration of the walls of historical buildings. However, lime coatings have insufficient resistance during operation. The purpose of this work was the modification of lime mortars with silicic acid sol in order to obtain more durable crystalline materials for construction purposes.

Unexpected Effects of Activator Molecules' Polarity on the Electroreological Activity of Titanium Dioxide Nanopowders.

Titanium dioxide nanoparticles, obtained using the sol-gel method and modified with organic solvents, such as acetone, acetonitrile, benzene, diethyl ether, dimethyl sulfoxide, toluene, and chloroform, were used as the filler of polydimethylsiloxane-based electrorheological fluids. The effect of electric field strength on the shear stress and yield stress of electrorheological fluids was investigated, as well as the spectra of their dielectric relaxation in the frequency range from 25 to 10 Hz. Modification of titanium dioxide by polar molecules was found to enhance the electrorheological effect, as compared with unmodified TiO, in accordance with the widely accepted concept of polar molecule dominated electrorheological effect (PM-ER).

[Effect of alkylresorcinols on thermal denaturation and refolding of bacterial luciferase and synthesis of heat shock proteins revealed in the luminescent molecular and cellular test systems].

Molecular and cellular luminescent biotests were used to reveal the effects of five alkylresorcinol homologues (C7-, C9-, C11-, C12-, and C18-AR) on the thermally induced denaturation and refolding ofbac- terial luciferases, as well as on the synthesis of heat shock proteins. The ARs activities were found to depend on their fine structure and concentration. Direct heat-protective effect of short-chain C7- and C9-AR on the chromatographically pure Photobactrium leiognathii luciferase/oxidoreductase was shown within broad range of concentration (10(-6)-10(-3) M).
