Validation of the infrared spectroscopy method for analysis of the composition of urine concretes.

The aim of this study was to validate the method for analyzing the composition of calculus using infrared (IR) spectroscopy by studying model mixtures of salts. Study was made with an ALPHA-P IR Fourier spectrometer with OPUS software (Bruker, Germany). The samples of pure chemical salts manufactured by Sigma-Aldrich USA were used to validate the method.

Endothelin-1 and nitrogen oxide metabolites in risk diagnostics of arterial hypertension in persons of young and middle ages occupied in harmful working conditions.

Hypertension is a global public health problem. One of the reasons contributing to the development of arterial hypertension is endothelial dysfunction, which is expressed in the imbalance of vasoactive indicators of vascular tone - nitrogen oxide and endothelin-1. Monitoring the indicators of endothelial dysfunction in workers exposed to harmful occupational factors will help to identify a risk group for the development of occupationally caused diseases of the cardiovascular system and, in particular, arterial hypertension, for early implementation of preventive measures.

Interregional differences of life expectancy in rural Russia - Assessment of socio-economic, demographic, behavioural and ecological factors.

The article is aimed at studying the effects of social, economic, demographic, behavioural and environmental factors on the life expectancy of rural people in different types of regions. Using cluster analysis, we identified four relatively homogeneous groups of Russian regions in terms of life expectancy. The impact of socio-economic, demographic and environmental indicators on life expectancy of the rural population was assessed using regression models.

Estimating the Impact of Economic Fluctuations on Unemployment in Russian Regions Based on the Okun Model.

Based on the modified Okun's model, the article evaluates the impact of changes in production volumes on the dynamics of unemployment in Russia and three regional clusters differing in the unemployment rate and behavioral responses to economic shocks. Assessing the specifications of the basic Okun model on the data of 2010-2020 made it possible to identify a cyclical reaction of the unemployment rate in heterogeneous regional clusters to changes in output volumes.
