Abstract: Aim.To evaluate the diagnostic value of heart-type fatty acid-binding protein (H-FABP) introduction to standard cardiac biomarkers in diagnostics of myocardial infarction (MI) early after clinical symptoms onset.Material and methods.Patients aged 18 years and older admitted to the hospital with acute coronary syndrome (ACS) during first 6 hours after ACS symptoms onset were enrolled into the study. At hospitalization level of biomarkers of myocardial damage (creatine phosphokinase-MB fraction - CPK-MB, troponin T) and qualitative tests on FABP were assessed in all patients. Serum troponin T concentration measured in 12 hours after the hospitalization was used to confirm diagnosis of MI. Moreover, diagnosis of MI was verified by echocardiography with the assessment of local reduction in myocardial contractility.Results.101 patients were included into the study (27% female; aged 59.9±12.4). At the moment of hospitalization 71 (70%) patients were diagnosed with ACS with ST-segment elevation, and 30 (30%) patients - ACS without ST-segment elevation. In total, period between clinical symptoms onset and hospitalization was 3.6±1.4 hours. Analysis of diagnostic value of tests during the first 6 hours after ACS symptoms onset showed higher sensitivity of H-FABP in comparison with troponin T and CPK-MB (72.5, 56.2 and 49.5%, respectively). Specificity of these tests during the first 6 hours after onset of clinical signs of ACS was 90, 100и 90%, respectively. Sensitivity and specificity were 87.7 and 100.0%, respectively, when H-FABP, troponin T and CPK-MB were used in combination as a “block test” in patients hospitalized during the first 6 hours after ACS symptoms onset. Sensitivity and specificity were 74.3и 100.0%, respectively, when “block test” was used in patients hospitalized during the first 3 hours after ACS symptoms onset; between 3 and 6 hours after ACS symptoms onset sensitivity and specificity of tests reached 100%.Conclusion.“Block test”with H-FABP, troponin T and CPK-MB early after ACS symptoms onset is more sensitive in comparison with separate use of the tests.
Permutation Generation Algorithm
O.V. Viktorov
Asian Journal of Information Technology , 2012,
Abstract: A new permutation generation algorithm is presented in this study. The algorithm has the fastest software implementation because it uses exchanges of two elements, but certain software overhead is present due to analysis of generating numbers and m-module forward-backward counters.
Significance of a Blood Flow Fractional Reserve Detection in Assessment of the Coronary artery Bifurcation Lesion Endovascular Treatment Effectiveness and Optimization
O.V. Britvina
Sovremennye Tehnologii v Medicine , 2010,
Abstract: Aim of investigation is a study of the blood flow fractional reserve measurement significance for optimization and assessment of the coronary artery lesion endovascular correction effectiveness.Materials and methods. An investigation of pressure in the coronary arteries was accomplished in a roentgenosurgical operating room with a use of the RADI Analyzer apparatus (Axle International). The results of endovascular interventions in 67 patients with the coronary artery bifurcation lesions are analyzed. An assessment of the coronary arteries in one group of patients was made on a basis of the selective coronarography data, and a measurement of a blood flow fractional reserve was made in the other group of patients beside a coronarography.Results. A circulation fractional reserve measurement is more significant for a bifurcation lateral branch state assessment because a negative correlation of its meanings and the selective coronarography results is established; the non-coincidences of the stenosis significance are mostly observed in the border stenosis group (II stage).
Energy-saving technical solutions for local and central microclimate systems using heat pumps as local aggregates united into one water circuit
O.V. Averyanova
Magazine of Civil Engineering , 2011,
Abstract: One of the priorities of energy savings is to implement energy saving measures in the work of heating systems, heating, ventilation and air conditioning systems based on heat pumps (HP). The dissertation considers using of a multizone central air-conditioning system with chilled beams for increase of power efficiency of a building was offered. In a transition period (the spring, autumn) in a building are observed both surplus of heat in one premises, and shortage of heat in others. At the expense of use low-temperature circuit and chilled beams of type "water-air" surpluses of heat are transferred in premises with shortages of heat and on the contrary. The given technology allows saving essentially thermal and electric energy in a transition period of year.
Economic efficiency of energy saving solutions (rus)
Averyanova O.V.
Magazine of Civil Engineering , 2011,
Abstract: One of the priorities in the development of Russian Federation is the policy of reducing energy consumption and implementation of energy efficient technologies. The article shows the example of the solution aimed at increasing the energy efficiency of systems which maintain optimal microclimate parameters in the office buildings. The solution is based on usage of WLHPS (Water Loop Heat Pump System). Consolidation into a united system makes it possible to utilize heat of the exhaust air heat and of other low-grade heat sources. The article shows the method of estimation the economic efficiency of these systems. The method is demonstrated on the example of office building. Comparison of various investment projects and selection the best solution was made by using economic indicators such as net present value (NPV) or the integrated effect and profitability index.

Children’s subculture as a component of social development of older pre-school children
Strelkova O.V.
Vestnik Immanuel Kant Baltic Federal University , 2013,
Abstract: This article discusses the features of psychological impact of culture (the communicative component of children’s subculture) on social development of a child of an older pre-school age.
