The results of studying the process and time of adaptation of two groups of the flying personnel who arrived from moderate climate to the subtropic climate show that the early stage of acclimatization lasts from two to four weeks, depending on the season. From the physiological point of view the best season is spring-summer. During this period the time of(More)
Catheter radiofrequency ablation of focal atrial fibrillation was successfully performed in a patient after closure of interventricular septal defect with a xeno-pericardial patch and plastic of tricuspid valve. The case demonstrates feasibility of carrying out such interventions under intracardiac echocardiographic guidance in patients with disturbed(More)
According to the modern ideas of the heart failure pathogenesis the noticeable contribution introduces ventricular dissynchrony which essence consists of the electrical and mechanical dissociation of different segments of the myocardium. In recent years the new method of cardiac resynchronization therapy has been worked out and achived good results. Its(More)
In this work we report the stimulation of astrocytic calcium signalling using an organic cell sensing and stimulating transistor (O-CST). We demonstrate that astroglial cells can adhere and proliferate on these devices giving us the possibility to stimulate bioelectrical activity in this type of cells. By the use of a microfluorimetric calcium imaging(More)
The nanostructure of micrometer-sized domains (bits) in phase-change materials (PCM) that undergo switching between amorphous and crystalline phases plays a key role in the performance of optical PCM-based memories. Here, we explore the dynamics of such phase transitions by mapping PCM nanostructures in three dimensions with nanoscale resolution by(More)
