Случай сочетания аденокарциномы верхней доли левого легкого и хондромы диафрагмы

The article describes a clinical case of comorbid peripheral lung cancer and extraskeletal chondroma of the diaphragm detected in the patient during chest computed tomography performed as a part of examination after renal colic. The X-ray signs of the masses were completely different, and those lesions were immediately identified as two different pathologies.Клинический случай сочетания периферического рака легкого и экстраскелетной хондромы из диафрагмы, выявленных у пациента при компьютерной томографии органов грудной клетки, выполненной по поводу обследования после почечной колики. Рентгенологическая картина образований была совершенно различна, и данные процессы были сразу расценены как два патологических процесса

Direct and remote results of treatment are considered

Development of an experimental plant and a numerical model of an axial magnetic rotor suspension

This article presents the results of the work on the creation of an experimental plant, its testing, as well as the development of a computational model of a rotor magnetic suspension with the use of axial electromagnets. The main purpose of producing the plant was to test the results of the developed numerical finite element model. An automatic control system was developed for the experimental installation. The electrical circuit was assembled on the basis of a ESP32 microcontroller with a clock frequency of 240 MHz and a PWM with a capacity of 10 bits. A PID-regulator program was developed. The coefficients kP, kD, kI used in the code of the electronic control system program (PID-controller) were selected. An experimental study of the bearing capacity of the axial active magnetic bearing under the influence of an external axial force was conducted. The required power of the axial active magnetic bearing was determined. The maximum load-bearing capacity of the installation for the selected coefficients of the PID-controller was determined. An axisymmetric finite-element model of the axial active magnetic bearing was created in the open-source program FEMM 4.2. The load-bearing capacity of the installation for a given current intensity value was calculated. The results of the numerical modelling were compared with the experimental data obtained. The basic principles of creation and operation of the experimental plant and its numerical model are outlined

Cardiovascular events follow-up analysis in patients with sinus node dysfunction and implanted pacemaker

Dysfunction of sinus node (DSN) is the syndrome, characterized by symptoms of tissue hypoperfusion and manifestations on the electrocardiogram and could potentially lead to sudden death. The various impact of different types of pacemakers on life quality and cardiovascular endpoints was shown.Aim. To analyze follow-up cardiovascular endpoints in patients with DSN and installed pacemakers.Material and methods. Six hundred and ten patients with DSN were analyzed in follow-up period (39,7±0,8 months) for unfavorable cardiovascular events (myocardial infarction, strokes, cardiovascular and non-cardiovascular hospitalizations).Results. Mortality rate differed depending on DSN variant (p=0,041), and most unfavorable was “tachy-brady” and sinoatrial node arrest + sinus node block III types. Also, the difference in mortality rate was shown for pacing variants (p=0,049) with maximal rate number of deaths was in ventricular pacemakers (24,6%) less — in dual-chamber pacemakers (11,7%) and minimal — in atrial (5,5%). No changes in cardiovascular endpoints was found between groups with sinus and pacemaker’s rhythm (p>0,5).Conclusion. In the follow-up analyze the difference between cardiovascular endpoints in patients in various types of pacemakers and regimen of stimulation was shown
