Efficiency of use of national games of Yakut people in studies of physical training in a higher education institution

The purpose of the present research is to demonstrate experimentally the positive effect of the Yakut national games on the formation of the basic physical qualities of the students of the university. The students of NEFU participated in research. In studies of experimental groups Yakut national games with objects and without objects were included. Traditional games of Yakut people in the lessons on physical education, served as means of dynamic development of physical qualities such as strength, speed, flexibility, endurance and agility

The electrophysical properties of polytolans and polydiphenylbutadiyne and the relationship between these and supermolecular structure

A polymer of tolan, obtained by thermal polymerization, and polymers of tolan and diphenylbutadiyne, obtained by anionic polymerization, have been studied by the space charge-limiyted current method. The energy of activation for conduction, the mobility and concentration of the charge carriers and the density and depth of the traps were found. It is shown that in polymers containing a conjugated double bond system there are traps grouped about fundamental trapping level. © 1977

Experience in implementing a program for basic life support and available automated defibrillation in a cancer center

Unified approaches to ensuring the chain of survival can improve the patient’s prognosis both in out-of-hospital and in-hospital cardiac arrest.Aim. To discuss practical issues of introducing a program for the availability of automated external defibrillation in a cancer center.Material and methods. For four years, our healthcare facility has been implementing a training program for basic and advanced life support according to the European Resuscitation Council standards, combined with the creation and development of an infrastructure for the availability of automatic defibrillation. A roadmap and infrastructure were developed for the project implementation.Results. In 2018-2022, 229 employees (114 doctors, 85 nurses and 30 nonmedical workers) were trained under the basic life support program. Fifteen defibrillators were placed in various units. During the specified period, first aid in case of sudden cardiac arrest using an automated external defibrillator before the resuscitation team arrival was independently provided by doctors and nurses of departments three times. To implement training in the continuous education system, the curriculum has passed the examination and accreditation in the edu. rosminzdrav system.Conclusion. The development and implementation of such initiatives requires significant organizational and methodological work, including continuous education system. However, in our opinion, this is an extremely useful tool for improving the safety and quality of medical care

The experience of radiofrequency ablation of atrial tachycardia focus with the use of high-density myocardial mapping

The article presents a case of successful treatment of focal atrial tachycardia by radiofrequency ablation using high-density myocardial mapping. The aim of the work was to evaluate the possibilities of high-resolution myocardial mapping by EnsitePrecision® navigation system in the treatment of complex arrhythmias. The analysis of clinical data and results of electrophysiological examination of a 29-year-old patient with continuous recurrent focal atrial tachycardia was carried out. The patient was admitted with complaints of heart rate disorders and frequent short attacks of palpitations. According to electrocardiography, frequent short paroxysms of focal atrial tachycardia were revealed. The patient was taken for electrophysiological examination and radiofrequency ablation of the focus of atrial tachycardia. The focus of atrial tachycardia was located in the anterior septal part of the left atrium, which is a rare localization. After radiofrequency ablation tachycardia was terminated, no complications and recurrences were registered. The patient was discharged with the sinus rhythm. Navigation system EnsitePrecision® enables conducting high-density myocardial mapping, which helps to accurately determine the localization of the source of tachycardia. The radiation load on the patient and ablation time are reduced, which reduces the frequency of complications from the procedure

Initial observations of fine plasma structures at the flank magnetopause with the complex plasma analyzer SCA-1 onboard the Interball Tail Probe

International audienceThe fast plasma analyzer EU-1 of the SCA-1 complex plasma spectrometer is installed onboard the Interball Tail Probe (Interball-1). It provides fast three-dimensional measurements of the ion distribution function on the low-spin-rate Prognoz satellite (about 2min). The EU-1 ion spectrometer with virtual aperture consists of two detectors with 16 E/Q narrow-angle analyzers and electrostatic scanners. This configuration allows one to measure the ion distribution function in three dimensions (over 15 energy steps in 50 eV/Q?5.0 keV/Q energy range in 64 directions) in 7.5 s, which makes it independent of the slow rotation speed of the satellite. A description of the instrument and its capabilities is given. We present here the preliminary results of measurements of ions for two cases of the dawn low- and mid-latitude magnetopause crossings. The properties of observed ion structures and their tentative explanation are presented. The 12 September 1995 pass at low latitude at about 90° solar-zenith angle on the dawn side of the magnetosphere is considered in more detail. Dispersive ions are seen at the edge of the magnetopause and at the edges of subsequently observed plasma structures. Changes in ion velocity distribution in plasma structures observed after the first magnetopause crossing suggest that what resembles multiple magnetopause crossings may be plasma blobs penetrating the magnetosphere. Observed variations of plasma parameters near magnetopause structures suggest nonstationary reconnection as the most probable mechanism for observed structures

Deoxygenation affects composition of membrane-bound proteins in human erythrocytes

Background/Aims: ATP release from erythrocyte plays a key role in hypoxia-induced elevation of blood flow in systematic circulation. We have previously shown that hemolysis contributes to erythrocyte ATP release triggered by several stimuli, including hypoxia, but the molecular mechanisms of hypoxia-increased membrane fragility remain unknown. Methods: In this study, we compared the action of hypoxia on hemolysis, ATP release and the composition of membrane-bound proteins in human erythrocytes. Results: Twenty minutes incubation of human erythrocytes in the oxygen-free environment increased the content of extracellular hemoglobin by ∼1.5 fold. Paired measurements of hemoglobin and ATP content in the same samples, showed a positive correlation between hemolysis and ATP release. Comparative analysis of SDS-PAGE electrophoresis of erythrocyte ghosts obtained under control and deoxygenated conditions revealed a ∼2-fold elevation of the content of membrane-bound protein with Mr of ∼60 kDa. Conclusion: Deoxygenation of human erythrocytes affects composition of membrane-bound proteins. Additional experiments should be performed to identify the molecular origin of 60 kDa protein and its role in the attenuation of erythrocyte integrity and ATP release in hypoxic conditions
