    The authors of the article identified four basic functions of the use of information technology in the course of training future representatives of a profession: information and training, forming, evaluation and correction, research.  It is noted that these functions do not operate separately, but as elements of a single system, depending on the conditions determined by the features of the information EE. The analysis allows the authors of the article to assert that at this stage of the educational process evolution the main task is to create a methodology related to the use of information management technologies in the development of electronic materials of educational nature and their implementation in the context of pedagogical activity.Los autores del artículo identificaron cuatro funciones básicas del uso de la tecnología de la información en el curso de la capacitación de futuros representantes de una profesión: información y capacitación, formación, evaluación y corrección, investigación.

    Luminosity-dependent changes of the cyclotron line energy and spectral hardness in Cepheus X-4

    Context. X-ray spectra of accreting pulsars are generally observed to vary with their X-ray luminosity. In particular, the hardness of the X-ray continuum is found to depend on luminosity. In a few sources, the correlation between the energy of the cyclotron resonance scattering feature (CRSF) and the luminosity is clear. Different types (signs) of the correlation are believed to reflect different accretion modes. Aims. We analyse two NuSTAR observations of the transient accreting pulsar Cep X-4 during its 2014 outburst. Our analysis is focused on a detailed investigation of the dependence of the CRSF energy and of the spectral hardness on X-ray luminosity, especially on short timescales. Methods. To investigate the spectral changes as a function of luminosity within each of the two observations, we used the intrinsic variability of the source on the timescale of individual pulse cycles (tens of seconds), the so-called pulse-to-pulse variability. Results. We find that the NuSTAR spectrum of Cep X-4 contains two CRSFs: the fundamental line at ~30 keV and its harmonic at ~55 keV. We find for the first time that the energy of the fundamental CRSF increases and the continuum becomes harder with increasing X-ray luminosity not only between the two observations, that is, on the long timescale, but also within an individual observation, on the timescale of a few tens of seconds. We investigate these dependencies in detail including their non-linearity. We discuss a possible physical interpretation of the observed behaviour in the frame of a simple one-dimensional model of the polar emitting region with a collisionless shock formed in the infalling plasma near the neutron star surface. With this model, we are able to reproduce the observed variations of the continuum hardness ratio and of the CRSF energy with luminosity

    Obesity pharmaceutical correction in metabolic syndrome patients

    Very high prevalence of obesity and metabolic syndrome (MS) is well known. The need for early treatment start and more selective pharmaceutical treatment of MS has been noted in many publications. As pathogenetic therapy, numerous methods for body mass (BM) reduction have been proposed, due to well-known prevalent role of obesity in MS pathogenesis. Because of various reasons, many medications haven’t achieved wide acceptance in clinical settings. The article summarizes the experience in BM reduction with an effective drug – orlistat (Xenical®). Based on the authentic authors’ data, beneficial effects of orlistat on carbohydrate and lipid metabolism, 24-hour blood pressure profile, and cerebral perfusion are demonstrated. The authors prove that orlistat is highly recommended for cardiovascular complication risk reduction in MS patients

    Aim. To assess the rate of acute kidney injury (AKI) development, incl. the necessity of renal replacement therapy (RRT), to evaluate the risk factors and outcomes of AKI.Material and methods. In the study, 2958 patients included, after a variety of cardiosurgical operations. The stage of AKI and indications for RRT were set based on the criteria of Kidney Disease: Improving Global Outcomes.Results. The rate of AKI development in general was 14%. AKI 1 stage was diagnosed in 10,2% (n=303), stage 2 in 3% (n=88) and stage 3 in 0,8% (n=23). RRT was implemented in 1,3% (n=38) of patients. The rate of AKI development post single coronary bypass (CBG) was 9,5% (n=35), single valve replacement (VR) and/or valve plastics (VP) — 19,8% (n=35), CBG+VR+VP — 33% (n=84), combination operations — 19,5% (n=107). Necessity of RRT post CBG — 0,3% (n=6), post VP/ VR — 0,56% (n=1), post CBG+VR/VP — 5,5% (n=14), post combination surgeries — 3% (n=17).Conclusion. The risk factors for AKI: age, body mass index, left atrium volume index, surgery type, the syndrome of low cardiac output, atrial fibrillation in early post operation period, inotropic and vasopressory support, lactat-acidosis. Development of AKI does prolong hospitalization time and increase mortality
