The Republic

The spatial organization of productive forces, the efficient use of available facilities, and the production potential assessment of economic sectors in a given region are topical issues. The Republic of Sakha (Yakutia) is a large resource-dependent region of Russia, remarkable for the geographical dispersion of deposits over a vast territory and the complex transport and power supply infrastructures. This paper presents a comprehensive assessment of the feasibility of cluster organization in the subsoil use sector in the Republic of Sakha (Yakutia), the Russian Federation, factoring in the existing and prospective economic zoning and the existing potential. The republic was divided into zones based on a cluster framework of the subsoil users. The study used statistical data on the municipal districts and financial indicators of the extractive industry companies. The integrated method was applied in the assessment, and the performance index of the identified cluster territories was calculated on a ten-point scale. The identified zones were rated by resource and production potential. The general cluster zone performance index was calculated. It appeared feasible to cluster the extractive industry in the studied region as it can increase competitiveness of local companies and contribute to the socio-economic development of its municipal districts. The proposed method can be applied for comprehensive assessment of the subsoil use sector in northern territories.

Dead End

Introduction Echocardiographic indices can form the basis of the diagnosis of systolic and diastolic left ventricular (LV) dysfunction in patients with Mitral regurgitation (MR). However, using echocardiography alone may bring us to a diagnostic dead-end. The aim of this study was to compare N-Terminal pro B-natriuretic peptide (BNP) and echocardiographic indices in patients with mitral regurgitation. Methods 2D and Doppler echocardiography and BNP serum level were obtained from 54 patients with organic mild, moderate and severe MR. Results BNP levels were increased with symptoms in patients with mitral regurgitation (NYHAI: 5.7 ± 1.1, NYHAII: 6.9 ± 1.5, NYHAIII: 8.3 ± 2 pg/ml, P < 0.001). BNP plasma level were significantly correlated with MPI (myocardial performance index) (r = 0.399, P = 0.004), and following echocardiographic indices: LVEDV (r = 0.45, P < 0.001), LVESV (r = 0.54, P < 0.001), LVEDD (r = 0.48, P < 0.001), LVESD (r = 0.54, P < 0.001), dp/dt (r = −0.32, P = 0.019) and SPAP (r = 0.4, P = 0.006). Conclusion The present study showed that BNP may be useful in patients with MR and may confirm echocardiographic indices.
