Urolithiasis is one of the most common urological diseases, occurring in at least 3% of the human population and 34.2% of the Russian population. Data from the Ministry of Health of the Russian Federation show that in the past 4 years, the incidence of urolithiasis has increased from 405.2 to 460.3 patients per 100,000 population. The purpose of this study was to assess the significance of determining the density of urinary stones via computed tomography, as well as the chemical composition of urinary stones, in order to choose an optimal treatment strategy for patients with urolithiasis. The results of treatment of 108 patients with stones of different localization and sizes were investigated. The patients were subjected to laboratory examination to determine the urinary salt environment; moreover, the levels of electrolytes were examined in blood samples from the patients, and computed tomography densitometry was performed to determine the density of the detected stones. The qualitative chemical compositions of urinary stones in patients with urolithiasis were determined. The density of urinary stones was evaluated by computed tomography densitometry in these patients. The relationship was determined between the chemical compositions of stones and their corresponding densitometric densities. The densitometric density of urinary stones, as determined by computed tomography, can serve as a predictor of the effectiveness of stone disintegration, because it allows selection of the best method to destroy stones for treatment of urolithiasis.

Introduction. Urolithiasis is a multifactorial recurrent disease, unevenly spread throughout the world and characterizedby the formation of urinary stones of various chemical compositions, depending on pathogenesis, etiological, and epidemiological risk factors. Understanding the composition of chemicals and their prevailing ratios can help make decisions about treatment tactics, preventive measures to reduce the risk of recurrence and the prevalence of urolithiasis.Purpose of the study. To assess the distribution of chemical components in urinary stones along with an analysis of their population significance.Materials and methods. The urinary stones were obtained from 2854 patients with urolithiasis. The composition of urinary stones was analyzed by using an infrared spectroscopy method.Results. The predominance of oxalate stones was determined in multicomponent kidney stones (83,7%) and the prevalence of urate stones (54,2%) was revealed in monocomponent kidney stones. Urinary stones with a predominance of oxalates contained significantly fewer impurities (12.4%) than urinary stones with a predominance of urates, phosphates and carbonates with an average amount of impurities >24.0%.Conclusion. The analysis of urinary stones distribution based on pathogenic factors showed that the calcium metabolism disturbances prevail in the population of the Russian Federation (88.0%).

The objective: to еxplore the relationship between the activity of endometrial proliferation and the state of the local immune response in the uterus in the conditions berprestasi process. Patients and methods. Examined 228 women of reproductive and perimenopausal age with endometrial pathology using ultrasound and then performing hysteroresectoscopy. Determination of the concentrations of the cytokines IL-1, IL-2, IL-6 and TNF was performed by solid phase ELISA. Results. Found a trend that confirms the loss of sensitivity to hormones at the stage of malignancy of the endometrium and can be used as diagnostic determinants in determining the nature of intrauterine pathology and criterion of the effectiveness of conservative therapy. Conclusion. Improving etiopatogenetice approach to the therapy of hyperplastic proce.sses of endometrium with determination of receptor phenotype of the endometrium is a research direction in modern gynecology, which will help to improve the results of treatment and prevention of intrauterine pathology. Key words: endometrial hyperplasia,the receptors for progesterone and estrogen, immunohistochemical method.

With the growing aridity of the climate on the Don, it became necessary to improve the methodology for conducting the  breeding of spring durum wheat. The main method of obtaining the source material remains intraspecific step hybridization. Crossings were performed between genetically distant forms, differing in origin and required traits and properties. The use of chemical mutagenesis was a productive way to change the heredity of genotypes in terms of drought tolerance. When breeding for productivity, both in dry years of research and in favorable years, the most objective markers were identified — the size of the aerial mass, the mass of grain per plant, spike, and harvest index. The magnitude of the correlation coefficients between the yield per unit area and the elements of its structure is established. It was most closely associated with them in dry years, while in wet years it decreased. Power the correlation of the characteristics of the pair - the grain yield per square meter - the aboveground biomass averaged r = 0.73, and in dry years it was higher (0.91) than in favorable ones (0.61 - 0.70) , between the harvest and the harvest index - r = 0.81 (on average). In dry years, the correlation coefficient increased to 0.92. Research data confirms the greatest importance of the mass of grain from one ear and the plant in the formation of grain yield per unit area in both dry and wet years. In dry years, the correlation coefficient between yield and grain mass per plant was on average r = 0.80; in favorable years, r = 0.69. The relationship between yield and grain mass from the ear was greater — r = 0.84 and r = 0.82, respectively. Consequently, the breeding significance of the aboveground mass and the productivity of the ear, as a criterion for the selection of the crop, especially increases in the dry years. They were basic in the selection.

Radin Inten II Airport is a national flight in Lampung Province. In this study using the technical analysis stated preference which is the approach by conveying the choice statement in the form of hypotheses to be assessed by the respondent. By using these techniques the researcher can fully control the hypothesized factors. To determine utility function for model forecasting in fulfilling request of traveler is used regression analysis with SPSS program. The analysis results obtained that the passengers of the dominant airport in the selection of modes of cost attributes than on other attributes. From the result of regression analysis, the influence of independent variable to the highest dependent variable is when the five attributes are used together with the R square value of 8.8%. The relationship between cost, time, headway, time acces and service with the selection of modes, the provision that states whether or not there is a decision. The significance of α = 0.05 with chi-square. And the result of Crame's V test average of 0.298 is around the middle, then the relationship is moderate enough.
