Efficiency and Prospects of Diagnosis of the Functional State of the Dental System.

This paper presents the results of studying the effectiveness of the developed method for diagnosing the functional state of the dental system. The results indicate that the accuracy of the method is about 80%. The results of previous studies are reviewed and the prospects for diagnosis of the functional state of the dental system as a research and practical trend in dentistry are outlined.

[THE DYNAMICS OF THE MORBIDITY RATE OF HEMORRHAGIC FEVER WITH RENAL SYNDROME IN THE POPULATION OF THE CITY OF NABEREZHNYE CHELNY].

In the article there are considered the environmental and biological prerequisites for the dynamics of hemorrnagic fever with renal syndrome (HFRS) morbidity rate in the population of the city of Naberezhnye Chelny and the municipal districts located in the north-eastern part of the Republic of Tatarstan, a subdivision of Russian Federation. The territory of the Republic of Tatarstan is included into the body of Volga Federal District of the Russian Federation and is located within the boundaries in coniferous taiga and temperate forests, forest-steppe and steppe geographical areas. The endowment of large forests as well as weather and climatic conditions play an important role in the activity and rhythmicity of this natural focal viral infection, the virus carriers of which are mouse-like rodents.

[Cellulose synthase genes that control the fiber formation of flax (Linum usitatissimum L.)].

Four cellulose synthase genes were identified by analysis of their class-specific regions (CSRII) in plants of fiber flax during the "rapid growth" stage. These genes were designated as LusCesA1, LusCesA4, LusCesA7 and LusCesA9. LusCesA4, LusCesA7, and LusCesA9 genes were expressed in the stem; LusCesA1 and LusCesA4 genes were expressed in the apex part of plants, and the LusCesA4 gene was expressed in the leaves of fiber flax.

[Supramolecular complex of extracellular bone matrix initiating biological mineralization].

A water insoluble supramolecular complex was isolated from bovine mature compact bone. It consists of approximately equal amounts of collagen, Ca-binding proteins and polar lipids that stimulate precipitation of calcium orthophosphates and their transformation into hydroxyapatite. Mechanism of participation of this complex in biological mineralization under physiological conditions and heterotopical calcification is discussed.

[Acoustic microscopy application for the evaluation of restorative materials bonding quality. Experimental investigation].

Ultrasound transmission and reflection at the interface between restorative material and tooth tissue have been investigated using experimental flat-parallel models and whole extracted human teeth with restorations. It has been found that in the case of good bonding the ultrasound wave energy practically does not reflect at the cement/dentin interface and propagates into dentin layer. If any microscopic cavity had been formed between cement and dentin, the most part of the acoustic energy would be reflected from the interface between cement and gaseous or liquid contents of that cavity.
