Patterns of Bioelectrical Brain Activity of Stroke Patients after Using Neurofeedback in the Rehabilitation Process

Background: Stroke patients develop the ability to perform higher levels of functional activity on basis of concentrated rehabilitative training which affects sensory, motor and cognitive functions. Objective: The main aim of our work was to show the usefullness of neurofeedback therapy in rehabilitation of stroke patients. Design: 27 stroke patients with severe disabilitis were included in the pilot study (men aged 32 to 68 years, mean age 52.4 ± 3.29 years, median 57 years). They all underwent complex study of brain bioelectrical activity EEG and 15 trainings of neurofeedback. Results: By the end of the rehabilitation (after 17 sessions) recollection of psychotrauma led to an increase in the power of the alpha rhythm in both left and right hemispheres. Atthe endpoint of the study differences in the power of the alpha rhythm in the left hemisphere were 1.47 times greater, and in the right hemisphere, 1.95 times greater than at the first visit. The regress of theta rhythm (1.25 times in the left, 1.11 times in the right hemisphere) decreased considerable, which affected the alpha / thetaratio - decreased 1.04 times in the left, 1.18 times in the right hemisphere, and also the coefficient (alpha + theta) / beta - decreased 1.17 times in the left and 1.21 times in the right. Differences in the saturation of blood vessels index at the last visit were 1.69 times greater than at the first visit. Neurophysiological changes correlated with an improvement in the emotional shpere. By the time of discharge, the indicators on the Beck depression scale decreased by 1.4 times, on the Spielberger-Khanin scale, situational anxiety decreased by 1.63 times, personal anxiety - by 1.4 times; regression of indicators in the hospital scale of anxiety and depression (HADS) was observed in 1.89 times. Conclusion: The data presented indicate that the use of the neurofeedbackmethod leads to a reduction of anxiety-depressive disorders, which positively affects the usefulness of combine rehabilitation.

Concept of TRAITOR in National Consciousness of Native Speakers of Russian and Chinese Languages (according to Data of Associative Experiment)

The results of two associative experiments are presented. Russian-speaking respondents were presented with the word-incentive predatel’ ‘traitor,’ Chinese respondents - with the word-incentive 背叛者 (bèipànzhě / traitor). The psycholinguistic experiment involved 300 subjects aged 18-45. The aim of the study is to compare the ways of linguistic representation of the concept of TRAITOR in the Russian and Chinese linguistic cultures. The associative fields of the Russian concept of TRAITOR and the corresponding Chinese concept are modelled. The interpretation of the results of the experiment in the Russian-speaking audience shows that the core of the associative field of the concept of TRAITOR is formed by the symbols of values and military vocabulary, and its near periphery consists of semantic groups “violation of norms,” “historical memory,” “religion.” Based on the data of the experiment conducted with Chinese informants, the associative field of the TRAITOR concept was modelled, the core of which includes associates representing the conceptual features of “historical memory” (names of parties, names of politicians, designations of events) and “war.” It is found that the basic layer of the concept, relevant to the Chinese linguoculture, is formed by the concepts of “anti-value” and “violation of norms.” It is reported that the near periphery includes associations of semantic groups “feelings and emotions” and “a bad person.

Growth and age of the roughhead grenadier Macrourus berglax in waters off Southwest Greenland

Data on the age and growth of the roughhead grenadier Macrourus berglax from waters off Southwest Greenland have been obtained based on the analysis of otoliths. Specimens with a preanal length of 5−39 cm, a weight of 7−5275 g, and age from 2 to 22 years are recorded in trawl catches. Roughhead grenadier exhibits a similar rate of linear growth in waters off Southwest Greenland and other parts of the range in the Northwest Atlantic. No considerable differences from the rate of the linear growth calculated earlier from scales for the species in waters off West Greenland have been found. In the recent period, the rate of weight gain in roughhead grenadier in waters off Southwest Greenland has been lower than in the Northwest Atlantic in the first half of the 1980s. The age of mass maturation in males (7–9 years) and females (16–17 years) in waters off West and East Greenland is somewhat higher than in coastal waters of Norway and the Northwest Atlantic

Age and growth of blue Antimora Antimora rostrata (Moridae) in Southwestern Greenland waters

The results of determination of age and study on growth of blue antimora Antimora rostrata from the waters of Southwestern Greenland are presented. The results are based on the analysis of 200 fish otoliths. In the catches, we found specimens of antimora with total lengths of 18−70 cm, body weights of 23−2731 g, at the age of 7−38 years. Minimal age of males (not considering juvenile individuals) was 10 years at body length of 27−33 cm; maximal age was 18 years at 42 cm. Minimal age of females was 9 years at length of 21–27 cm; maximal age was 38 years at 70 cm. The rate of linear growth in blue antimora from Southwestern Greenland waters is comparable to that in the fish from New Zealand and Ross Sea waters but considerably lower than indicated earlier for fish from the waters of Iceland, Greenland, and the Mid-Atlantic Ridge. The age of reaching sexual maturity in males and females is preliminary determined as 15 and 19−20 years, respectively

Institutional analysis of the regulatory and legal framework for financial reporting control in Russia

The study contains the main approaches to the determination of various institutions affecting Russian accounting from the standpoint of their formal and informal types. In modern conditions, the economic actions of a subject must be matched to external factors that determine the correctness of economic decision-making, as well as consistency and the development of correct patterns and behavior algorithms that are most effective for each specific situation. Through the institutional analysis, the authors have identified several inconsistencies in the regulatory framework of related institutions and suggested ways to eliminate these disparities. Inter-institutional discrepancies have been found between law and accounting institutions, indicating non-compliance in the accounting practice of the substance over form principle, between recognition in the bookkeeping and tax accounting of the transfer of assets and liabilities ownership, as well as differences in the recording of investment real estate in the financial statements according to IFRS institutions and Russian national standards.peer-reviewe

The author explores the essence of Russian statement of financial position of state sector entities. The approach to the features of the balance sheet is based on analyzing the classification of legal entities in the norms of the Civil Law of the Russian Federation. The objective of the article is determination of public sector reporting entity as well as a development of draft report on the financial position of the public sector entities. The author applies the institutional methodology in evolving perceptions of financial statements the reporting public sector entities have developed in the context of transition to international public sector accounting standards (hereinafter - IPSAS). The methodology is based on a detailed analysis of the legal framework of various related institutions: law, budget accounting, international financial reporting standards (hereinafter - IFRS) and other institutions. The results of the study justify and develop a new concept of public sector reporting entities. Given the new concept, the draft statement of financial position for Russian public sector entities was developed, which is universal for both state-owned (budgetary) and autonomous institutions.peer-reviewe

Statistical methods for analyzing financial statements of Russian organizations in the context of IFRS implementation

In the context of the transition to international financial reporting standards (hereinafter - IFRS), issues of bringing Russian financial statements closer to an international format are of relevance. In order to develop Russian reporting adapted to the new requirements of the format, the authors have conducted polls of the accounting services of large, medium and small business organizations about the desirability of including the indicators from the minimum list of international reporting articles in their reports. Based on the methods used by the Institute of Statistics in the study of Russian financial statements methods of selective observation, questioning, methods of processing the data obtained, namely, calculating the proportion of reporting indicators using the A. Salai and V. Ryabtsev index, the authors justify the inclusion in the Russian financial reporting a series of indicators proposed by IFRS. The results of the study can be used in the transformation of statements, as well as in the construction of consolidated financial statements generated in Russia in accordance with the requirements of IFRS.peer-reviewe

Treatment of clubfoot in young children with arthrogryposis by Ponseti method: possibilities and perspectives

Background. Clubfoot is the most common deformity in arthrogryposis and is characterized by a high degree of rigidity and a tendency to relapse. At present, no consensus exists on the issue of treatment of this pathology. The aim of this study was to demonstrate the possibilities of Ponseti method for the treatment of clubfoot in the younger children with arthrogryposis. Material and methods. The study was based on an analysis of treatment outcomes in 64 children (124 feet) under 3 years. 50 patients (78%) had a congenital multiple arthrogryposis, 14 children (22%) had a distal form of the disease. All the children underwent conservative treatment using Ponseti method. Results. After phased plastering by Ponseti method, the children with congenital multiple arthrogryposis aged under 1 year demonstrated correction of deformity components in 25 (48%) feet and the children from 1 to 3 years in 4 (8.7%) feet. Phased plastering in the children under 1 year with the distal form of the disease resulted in the correction in all 7 (100%) feet. In the patients with a similar form of the disease aged from 1 to 3 years, correction was achieved in 3 (23%) feet. In the cases of incomplete correction of deformity elements, when the possibilities of phased plastering were exhausted, different surgical interventions were performed. However, in neither case the surgery to remove talus was required. Conclusion. Ponseti method is most effective for the treatment of clubfoot in the children of the first year. Application of this method allows for elimination of clubfoot or significant reduction of the volume of subsequent surgery
