Issues of financial assurance of economy greening in the regions

The relevance of the analyzed issue is caused by the need to internalize environmental externalities in the modern world. The purpose of the article is to examine the issue of financial support of the green economy using the example of the regions included in the Volga Federal District (VFD). The leading methods to the study of this issue is a comparative analysis of environmental taxes and charges in Russia and countries of the European Union (EU) and the analysis of environmental problems in the regions of the Volga Federal District, which allow identifying the shortcomings of the existing environmental payment system and proposing measures to modernize the system of financial support of the green economy. The key shortcomings of the existing environmental payment system: low rates of environmental payments; the inappropriate use of funds received from environmental payments; concentration of 97% of revenues from environmental payments in the federal budget. The contents of the article may be helpful for public authorities of general and special competence to develop the principal directions of environmental policy and plan activities aimed at improving the green economy. © 2016 Shekhova et al

Laboratory biomarker galectin-3 in the diagnostics of myocardial inflammatory changes in patients with atrial fibrillation

Atrial fibrillation (AF) is one of the most common cardiac arrhythmias. Numerous data indicate a significant contribution of myocardial inflammatory changes in the development and progression of AF. The search for new laboratory biomarkers to assess the activity of myocardial inflammatory processes, and the study of their diagnostic significance for noninvasive diagnosis in patients with AF is relevant. Therefore, the aim was to study the features of the serum level of the biomarker Gal-3 and to identify its relationship with inflammatory changes in the myocardium in patients with AF. Depending on the results of histological studies, the patients were divided into 2 groups: group 1 – with morphologically verified active lymphocytic myocarditis (ALM), group 2 – with lymphocytic infiltration (LI). Analysis of the frequency of detection and severity of the inflammatory process in the myocardium showed that activity of 4-5 scores was detected only in group 1. In 2nd group, activity of the inflammatory process in most patients was 1 score. All patients with LI mild interstitial inflammation were showed. In the ALM group moderate and severe interstitial inflammation was detected. A high number of CD3+ and CD45+ cells were found in 1st group compared to group 2 (p < 0.001).There were no significant intergroup differences in the serum level of Gal-3. At the same time, in 1st group showed a significant decrease in Gal-3 in 6 months after treatment (p = 0.028). Positive correlations of Gal-3 with the severity of the inflammatory process and endocardial involvement were revealed in patients with ALM. The association of serum Gal-3 levels with CD68+ levels in 1st group was detected (R = 0.48, p = 0.030). In 2nd group, a correlation between the level of Gal-3 in 6 months after ablation with infiltration of CD45+ cells was found (R = 0.69, p = 0.003). Thus, in patients with AF and active lymphocytic myocarditis, significant associations were established between biomarkers of Gal-3 and inflammatory changes in the myocardium. This confirms the important role of Gal-3 as a participant in the inflammatory process

Density of states in SF bilayers with arbitrary strength of magnetic scattering

We developed the self-consistent method for the calculation of the density of states $N(\epsilon)$ in the SF bilayers. It based on the quasi-classical Usadel equations and takes into account the suppression of superconductivity in the S layer due to the proximity effect with the F metal, as well as existing mechanisms of the spin dependent electron scattering. We demonstrate that the increase of the spin orbit or spin flip electron scattering rates results in completely different transformations of $N(\epsilon)$ at the free F layer interface. The developed formalism has been applied for the interpretation of the available experimental data.Comment: 5 pages, 8 figure

CIRCULATING BIOMARKERS OF SYSTEMIC INFLAMMATORY RESPONSE IN THE ASSESSMENT OF POSTPERICARDIOTOMY SYNDROME IN PATIENTS AFTER CARDIAC SURGERY

Postpericardiotomy syndrome (PCTS) is one of the most frequent cardiac surgery complications seen in 9-65% of patients. Despite its widespread occurrence, the mechanisms of the development of PCTS are still understudied. drug. The use of colchicine in cardiac surgery patients is of particular interest. Due to the ability of this drug the colchicine mechanisms of action are able to inhibit the mobilization of the NLRP3 inflammasome assembly, to suppress the activation of caspase-1. As a result, it can prevent the release of proinflammatory cytokines, namely IL-1β and IL-18. There are conflicting data on the effect of colchicine on the PCTS progression within the systemic inflammatory response after cardiac surgery. In this regard, it was important to study the dynamics of serum levels of IL-6, IL-10, IL-1β, and TNFα in patients before coronary artery bypass grafting (T1), 6 hours (T2), and 10 days (T3) after surgery, and to evaluate the effect of colchicine on the development of PCTS. The results of our research showed a significant increase of IL-10 in both groups 6 hours after surgery. However, on the 10th day, the increase in the level of IL-10, compared with the initial values, was higher in the 1st group – 2 times, compared with the 2nd group. In both groups, showed significant increase in serum concentration of IL-6 after 6 h surgery, with a subsequent decrease in the expression at the stage of T3, while the IL-6 levels in the 2nd group was statistically notably higher than T1. The incidence of pleurisy was lower in the group of patients taking colchicine. Only in the 1st group IL-6 levels were directly associated with IL-10. In patients with pleurisy, the level of released IL-10 and TNFα was significantly higher in the 2nd group. There were no significant intergroup differences in serum levels of IL-1β and TNFα, as well as significant changes in IL-1β between the stages of observation. Analysis of TNFα expression revealed significant differences in TNFα content in the 1st group between the T1-T3 and T2-T3 stages. In both groups, multiple positive associations were found between the studied indicators. Thus, data were obtained indicating the antiinflammatory effect of colchicine in cardiac surgery patients. This was clinically expressed in a tendency to a lower incidence of pleurisy, and was accompanied by increased expression of IL-10, which has an antiinflammatory and immunomodulatory effect against the background of the drug in the postoperative period

DYNAMIC CHANGES IN CARDIOVASCULAR RISK BIOMARKERS AND CYTOKINES OF MYOCARDITIS-FREE PATIENTS WITH DECOMPENSATED HEART FAILURE AND ISCHEMIC SYSTOLIC DYSFUNCTION

The development and progression of heart failure is associated with a variety of pathophysiological mechanisms, of particular interest is the study of the inflammatory response as a fundamental link in the pathogenesis of CHF and its main component – decompensation. An open, non-randomized, prospective study was carried out to evaluate the clinical and morphological features of subclinical inflammation in patients with acute decompensation of ischemic chronic heart failure with a reduced ejection fraction. The study included 25 patients with decompensated ischemic CHF with left ventricular ejection fraction < 40% aged 35 to 75 years (60.12±9.3 y. o.). In this study the dynamics of the serum content of C-reactive protein (CRP), N-terminal fragment of the brain natriuretic peptide precursor protein (NT-proBNP), soluble ST2(sST2), insulin-like growth factor-1 receptor (IGF-1R), interleukin-6 (IL-6), interleukin-10 (IL-10), tumor necrosis factor-α (TNFα) was performed by multiplex immunoassay using the FLEXMAP 3D. All studied patients were divided into two groups depending on the diagnosed myocarditis: patients with no signs of myocarditis and patients with myocarditis. It was found that in the group of patients with diagnosed myocarditis there was an increased content of CRP, IGF-1R, IL-6 and IL-10, TNFα compared to the group of patients without myocarditis. The median concentrations of the NT-proBNP and sST2 in both groups did not differ. At the follow-up visit a year later, there was a decrease in the content of CRP, NT-proBNP, IL-6 in both groups. In the group of patients with myocarditis, an increase in the content of sST2, IGF-1R, IL-10 was observed. Thus, the study carried out in dynamics revealed significant differences in the degree of changes in the serum activity of pro- and anti-inflammatory cytokines and biomarkers of cardiovascular risk in patients with decompensated heart failure with systolic dysfunction with diagnosed myocarditis and in its absence
