Influence of polymorphic folate gene variants on process of early pregnancy interruption at inhabitants of Adyghea Republic
For the first time a frequency distribution of alleles and genotypes of folate gene polymorphisms (MTHFR 677 C>T, MTHFR 1298 A>C, MTR 2756 A>G, ĚŇRR 66 A>G) is defined for inhabitants of Adyghea Republic, as well as the predictor importance of SNP (single nucleotide polymorphisms – single nucleotide replacements) of folate cycle genes at threat of pregnancy interruption in the first trimester is analyzed. A threat of pregnancy interruption in the first trimester at inhabitants of Adyghea Republic is associated with A66 allele (χ2=6,88; Đ=0,009; OR=3.98) and heterozygotic genotype of A66G gene of MTRR which increases 6 times risk of development of pathology (χ2=11,22; Đ=0,004; OR=6,15). “Normal” A66 allele of MTRR gene at the Russian women is related to threat of early pregnancy interruption (χ2=5,54; Đ=0,02; OR=4.72). The disturbances in the course of pregnancy at Adyghes, unlike the Russian women, are associated with “normal” C677 allele (χ2=6,32; Đ=0,01; OR=9.4) and C677C of MTHFR gene genotype (χ2=6.65; Đ=0,04; OR=19,3).

Control of level of adaptive capacity and carbon dioxide in the human body using modulated impulse hypoxia “Sfigmoton”
We have studied the dynamics of the adaptive capacity of an organism and the concentration of carbon dioxide in the arterial blood under the influence of technology “Sfigmoton” – impulse-frequency signals of pulse of person naturally adapted to the impulse hypoxia. The results of the study show that under the influence of the tested signal, there is an increase of the adaptive capacity of the organism, as evidenced by a significant decrease of adaptive capacity from the level of “stress adaptation mechanisms” to a “satisfactory adaptation” level. During the experiment we also observed the increase and stabilization of carbon dioxide levels in the organism, which in turn points to an increase in the degree of blood supply to vital organs that is of great importance in the conditions of high mountain hypoxia. Data, obtained as af-tereffect, evidence a prolonging impact of studied frequency of the modulated pulse and its high efficiency.

Morpho-anatomical analysis of Alchemillŕ orthotricha Rothm.
The paper describes the morphological properties of Alchemilla orthotricha Rothm. growing in the moist subalpine meadows of the Lago-Naki plateau in the Northern Caucasus. The following biometric parameters are considered: the length, width and size of the leaf surface area, and the length of the petioles of basal and stem leaves. The level of variation of these properties in the plants that grow in identical ecological conditions is medium. The characteristic features of the plant’s anatomic structure, as well as of the leaf, the petiole, and the root are thoroughly discussed. The petiole of the basal leaf has three concentric vascular bundles. The results of the microchemical analyses are provided.

On medical environmental monitoring of a state of health of the Adyghea Republic population
The paper deals with the prospects of the new scientific direction in Adyghea – a medical environmental mapping. Historically the territory of Adyghea is endemic on a number of the diseases which are transferred by the transmission way. Change of a climatic and ecological situation in the region increases risks of emergence of transmissive infections. Creation of special services of the medical environmental mapping will allow us to respond to the arising epidemic situations in due time.

Creation of neural network model by a method of the “neural network approximator” using the structured knowledge
A neural network model was developed by using a method of the neural network approximator with application of the structured knowledge. Features and advantages of a method in which there is a live broadcast of all knowledge bases in expert systems are specified. The modern gradient algorithms implemented by the principle of the return distribution of a mistake to reduce training time are studied. All these algorithms possess one essential shortcoming, namely: the choice of primary point for optimization. In most cases of application of multilayer neural networks, a problem of the choice of primary point of optimization is not paid necessary attention. Therefore, the appropriated accidental value is given to all weights. The publication considers the creation of structure of a neural network on the basis of trees of decisions, including calculation of primary values of scales of bonds as the main part of process of development of the neural network. It is shown how the obtained positive values of scales of bonds of an untrained neural network accelerate the process of network training.
