MicroRNA: markers of male infertility. The molecular basis of dysfunction and pathogenesis of male reproductive system are not fully known at the moment, but the results of several researches revealed that microRNAs play an important roles in precise regulation of post-transcriptional processes in spermatogenesis. It is involved in immune reactions, thermal and oxidative stress responses, it directs effects on proliferation and differentiation, chromatin compactification, apoptosis, affects the synthesis of functionally important proteins in the metabolism of spermatozoa, the synthesis of proteins involved in sperm motility, et cetera. All these facts are sufficiently confirm that differentially expressed in normal and pathological processes of sperm production  microRNAs can be used as reliable markers for different variants of patospermia. Considering that the spermatogenesis disturbance is one of the most significant cause  of male infertility, identification of specific microRNAs and studying of its regulatory mechanisms are very important for the formation of through understanding of the problem of male infertility and for the development of therapeutic methods. So, the main purpose of this article is compilation a literature review over the past six years on the topic of altered expression of microRNAs in seminal plasma, testicular tissue in several types of spermathogenesis abnormalities. In generally, analysis of the literature sources has shown that miR-15, miR-126, miR-449, miR-514, miR-517, miR-1260 are down-regulated and miR-99, miR-141, miR-193, miR-373, miR-429 are up-regulated in various pathologies of spermatogenesis. Expression profiling of the following microRNAs in various pathologies of spermatogenesis have also been repeatedly noted by researchers, but the concentration of each of them could be increased and decreased depending on the type of pathospermia: miR-16, miR-19, miR-26, miR-29, miR-30, miR-34, miR-122, miR-125, miR-181, miR-374, miR-509, miR-574.    

Ecological-modifying effect of soil contamination with heavy metals on the contact interaction of human leukocytes Evstropov Vladimir M. Don state technical University, Rostov-on-Don, Russia Abstract: It is known that by assessing the intensity of the contact interaction of lymphocytes with granulocytes, we can detect the processes of preclinical carcinogenesis. Heavy metals have carcinogenic properties, and the interaction of lymphocytes with granulocytes, which characterizes the level of transforming cells, is reduced in people permanently residing in the city, compared to people in rural areas [6], apparently under the influence of increased of anthropogenic environmental pollutions. At the same time, the contact interaction of lymphocytes with granulocytes can be considered as a cytological phenomenon, which characterizes the functional state of leukocytes, in particular their locomotor and adhesive potencies. Based on the characteristics of various functional zones of the city of Rostov-on-Don, established on the basis of the determination of the total indicator of soil contamination with heavy metals (zinc, arsenic, copper, lead and nickel), we carried out a comparative analysis of the activity of contact interaction of leukocytes of various types (lymphocytes and granulocytes) among the residents of two functional zones of the city, who differ in the degree of soil contamination with heavy metals: with moderately dangerous and acceptable levels of contamination. The results of the study showed that the residents of the functional zone of the city with a moderately dangerous level of soil contamination with heavy metals, the intensity of the interaction of the studied leukocytes was lower than that of those living in the territory with an acceptable level of pollution. We assume that the revealed decrease in the intensity of contact interaction of leukocytes in people long-term living in areas whose soil is moderately polluted with heavy metals is caused by chromosomal abnormalities and transformation of leukocytes, in particular lymphocytes.

The follicle-stimulating hormone receptor gene (FSHR) polymorphisms and hormon levels in women undergoing assisted reproductive treatment This study was performed to investigate the association between FSH receptor (FSHR) gene polymorphism at position 680 and the number of dominant follicles, also the FSH and LH levels before controlled ovarian hyperstimulation and after it. One hundred patients from 24 to 42 who underwent IVF-ET procedures were included in this study. Three groups were formed: patients with normal ovary response, patients with ovary hyperstimulation and patients with poor ovary response. The FSHR polymorphism was determined by polymerase chain reaction and restriction fragment length polymorphism analysis. The FSHR genotype distribution in patients with normal ovary response was 45,3%  for AA, 39,6% for AG and  15,1% for GG. There was no difference among the three genotype groups. The basal levels of FSH and levels after controlled ovarian hyperstimulation were significantly higher in patients with poor ovary response. LH levels after controlled ovarian hyperstimulation were significantly lower in patients with normal ovary response. The basal levels of AMH were significantly higher in patients with ovary hyperstimulation.

Optimization of information data analyzed in the process of neural network prediction outcome pathology of hemostasis Neural network systems for diagnostics and prognosis are actively introduced in clinical practices in last five years. These systems have higher detection sensitivity and specificity compared to traditional scales for valuation status severity. However the description most of these systems are not include information of principles and algorithms for selection neural network input parameters. Often this leads to redundancy of researched parameters, which in turn have negative impact upon work result of neural network systems. In this article proposed to the algorithm of informative parameters selection for information data optimization, analyzed in process neural network prognosis of outcome pathology hemostasis. neural network, algorithm, informative parameter.

Investigation of the activity some 8-aminoderivatives of 3-methyl- 7-?-hydroxi-?-isopropoxipropylxanthines at the experimental hyperlipidemia. Ostapenko А. А., Belay I. M., Romanenko N. I. We made research in analysis of the antioxidant features of the newly synthesized derivatives of 3-methylxanthine in experimental hyperlipemia in rats. The results of the computer prediction of the possible manifestations of the biological activities indicate that the majority of the analyzed compounds can influence on the different sides of lipid metabolism. Markers of the influence on the activity of lipid peroxidation and the complex antioxidant activity during administration  of derivatives 3-methylxanthine were studied. This screening has allowed to identify some patterns of connections between the structure and the direction and severity of changes in the antioxidant properties of the blood of experimental animals. In addition, prospect of further pharmacological studies of the effects of synthetic analogs of xanthine are confirmed by appropriate patents and informational letters.
