Increased motor cortex excitability during motor imagery in brain-computer interface trained subjects

Background: Motor imagery (MI) is the mental performance of movement without muscle activity. It is generally accepted that MI and motor performance have similar physiological mechanisms. Purpose: To investigate the activity and excitability of cortical motor areas during MI in subjects who were previously trained with an MI-based brain-computer interface (BCI). Subjects and Methods: Eleven healthy volunteers without neurological impairments (mean age, 36 years; range: 24–68 years) were either trained with an MI-based BCI (BCI-trained, n = 5) or received no BCI training (n = 6, controls). Subjects imagined grasping in a blocked paradigm task with alternating rest and task periods. For evaluating the activity and excitability of cortical motor areas we used functional MRI and navigated transcranial magnetic stimulation (nTMS). Results: fMRI revealed activation in Brodmann areas 3 and 6, the cerebellum, and the thalamus during MI in all subjects. The primary motor cortex was activated only in BCI-trained subjects. The associative zones of activation were larger in non-trained subjects. During MI, motor evoked potentials recorded from two of the three targeted muscles were significantly higher only in BCI-trained subjects. The motor threshold decreased (median = 17%) during MI, which was also observed only in BCI-trained subjects. Conclusion: Previous BCI training increased motor cortex excitability during MI. These data may help to improve BCI applications, including rehabilitation of patients with cerebral palsy.Web of Science7art. no. 0016

Dynamics of the Free Surface of a Conducting Liquid in a Near-Critical Electric Field

Near-critical behavior of the free surface of an ideally conducting liquid in an external electric field is considered. Based on an analysis of three-wave processes using the method of integral estimations, sufficient criteria for hard instability of a planar surface are formulated. It is shown that the higher-order nonlinearities do not saturate the instability, for which reason the growth of disturbances has an explosive character.Comment: 19 page

First mock-up of the CBM STS module based on a new assembly concept

A molecular dynamics model has been developed to investigate the effect of the crystallographic orientation on the material deformation behaviors in nano- indentation/scratching of BCC iron. Two cases with different substrate orientations have been simulated. The orientations along x, y and z direction are [001], [100] and [010] for Case I and [111], [-1-12] and [1-10] for Case II, respectively. Case I and Case II exhibit different deformation patterns in the substrate. During indentation, the pile-up can be observed in Case I, but not in Case II. During scratching the pile-up ahead of the movement of the indenter has been enlarged in Case I, while a chip with the disordered atoms is generated in Case II. It has been found that Case I has both higher hardness and larger coefficient of friction. The ratios of the hardness and the coefficient of friction between cases I and II are nearly 2. The reason is attributed to the different crystallographic orientations used in both cases

The clinical aspects ot the sulphonylurea compounds from the position of the cardioprotective approach at patient with type 2 diabetes, using glucocardiomonitoring

BACKGRAUND: Now the trend of Type 2 Diabetes Mellitus (T2DM) management from glucocentric to cardioprotective approach take place, and it especially relevant for the multiple group of patients with T2DM using Sulphonylurea (SU). Meanwhile the synchronized glucocardiomonitoring allowed to providing the accurate information about the cardiometabolic status of patients with T2DM.AIMS: Using the professional glucocardiomonitoring for T2DM-SU patients to investigate the relation between the glycemic variability, integral glycemic parameters and proarrhythmogenic cardiovascular events and the long-term cardiovascular outcomes.MATERIALS AND METHODS: In the observational (randomised for inclusion of patients) controlled trial the SU-patients with the T2DM duration 9,8±6,6 years were included, whom the professional glucocardiomonitoring had been made during 5 days and then the fatal and non-fatal cardiovascular events had been investigated during 5 years. RESULTS: From 283 patients with T2DM 154 patients (the basic group) used gliclazide (original drug Diabeton MB), 129 patients (the control group) used glibenclamide. The relation between the rising of the glycemic variability and cardiovascular events (the prolongation QT interval, the ST depression (dST), ventricular arrhythmias (VAs)) were demonstrated. At the basic and the control groups the coefficient of variation (CV) was 23,0±8,1 and 30,1±10,7% respectively (p<0,001), TIR-HYPO — 0,8±2,4 and 3,5±5,4% (p<0,001), the number of glycemia differences > 4 mmol/L/hr — 2,3±3,6 and 3,5±4,3 (p=0,010), the minimal glycemia level — 4,6±1,0 and 3,9±1,4 mmol/L (p=0,001). The followed differences of cardiovascular parameters were determined: QTc — 412±24 and 423±28 ms (p=0,001), dST — 0,052 [0; 0,275] and 0,109 [0; 0,422] (ratio, p=0,012), VAs — 2,2 [0; 5,9] and 3,5 [0; 8,3] (cases/pts, p=0,008). The long-term cardiovascular outcomes from the gliclazide and glibenclamide therapy (cases/100 pts-years): the total and cardiovascular death — 0,12 [0; 1,74] and 0,76 [0; 4,62] (p=0,062), cardiovascular death -0,12 [0; 1,74] and 0,62 [0; 4,08] (p=0,122), myocardial infarction — 1,56 [0; 6,94] and 2,00 [0; 8,02] (p=0,193), stroke — 0,78 [0; 4,66] and 0,76 [0; 4,62] (p=0,169), chronic heart failure — 0,52 [0; 3,72] and 1,24 [0; 6,06] (p=0,095), MACE — 2,46 [0; 10,1] и 2,62 [0; 9,38] (p=0,095), severe hypoglycemia at home — 2,46 [0; 9,12] и 7,24 [0; 16,68] (p<0,001).CONCLUSIONS: It was demonstrated that the gliclazide (original drug Diabeton MB) administration is characterized with the better quality of glycemia control, the lower glycemic variability, the lower frequency of the SU-associated hypoglycemia, dST, VAs, the lower prolongation QTc interval. The implementation of the synchronized glucocardiomonitoring is necessary for minimization of the cardiovascular T2DM-complications and for the choice of the personalize

Increase of Competitiveness of Tourist Industry Companies on the Basis of Marketing Approaches

Under the modern conditions of quick development of tourism in the world, which sets strict requirements to the level of work of tourist companies, there is an urgent need for systemic study of general and specific attributes of tourist business, its organization, regularities of development and management, and its intersectoral and infrastructural interconnections. The article studies peculiarities of development of tourist market in Russia and factors of development of tourism under the conditions of economic instability, determines top-priority directions of state’s support for tourist industry, distinguishes main attributes of tourist services which should be taken into account during marketing research, and determines main stages of marketing research. It is determined that under the conditions of economic and political instability, the necessity for re-orientation of the flow of international outbound Russian tourism at the development of internal tourism is obvious, and development of tourist industry requires a complex of measures that consists in formation of effective system of marketing, thus leading to the necessity for satisfaction of needs of foreign and internal tourists in the region of stay. The main purpose of this article is to determine factors of development of tourism under the conditions of economic instability and develop methodological instrumentarium for increase of competitiveness of tourist industry enterprises under the modern conditions. The authors use the data received as a result of research, conducted with the use of methods of statistical and graphical analysis, which allowed reflecting specifics of tourist market in Russia and of strategic segmenting. The result of implementation of these measures of tourism development and use of marketing instrumentarium will be the creation of modern and technically equipped tourist industry, capable of satisfying needs of Russian and foreign citizens.
