Professional Idioms in a Practical Course of Russian Language for Foreigners (based on the Language of Medicine)
The article is devoted to the problem of forming professional communicative competence of foreign students. The main attention is paid to professional phraseological terms, because they (due to their idiomatic nature) often have national and cultural specifics, causing considerable difficulties in studying. Material for analysis was the author's card file of medical phraseological units (more than 100 units), compiled on the basis of dictionaries of medical terms and works on the vocabulary of the medical field. Based on the traditional definition of phraseological units as stable formations, the importance of which is not motivated by the values of the components included in them, the authors offered several classifications of medical phraseological units. In teaching phraseological units it is advisable to use classifications based on structural or semantic principles. It is shown that the division of phraseological units that is traditional for linguistics in terms of the degree of adhesion of words in their composition cannot be used in a foreign language audience, since students have difficulties in understanding this criterion. The article substantiates the necessity of studying medical phraseology already at the initial stage of mastering the language of the profession. The system of tasks (for the initial and advanced stages of learning of Russian language) is proposed, the sequence of which is determined by the structure and semantics of phraseological units. Recommendations for working with professional phraseology can be applied when studying by foreign students of Russian professional idioms not only in medical schools, but also in other universities that provide training for students in other areas

Strong short-range magnetic order in a frustrated FCC lattice and its possible role in the iron structural transformation
We investigate magnetic properties of a frustrated Heisenberg antiferromagnet
with a face-centered cubic (FCC) lattice and exchange interactions between the
nearest- and next-nearest neighbours, J1 and J2. In a collinear phase with the
wave vector Q = (pi,pi,pi) the equations of the self-consistent spin-wave
theory for the sublattice magnetization and the average short range order
parameter are obtained and numerically solved. The dependence of the Neel
temperature T_N on the ratio J2/J1 is obtained. It is shown, that at strong
enough frustration there is a wide temperature region above T_N with strong
short range magnetic order. Application of this result to description of
structural phase transition between alpha and gamma-phase of Fe is considered
The p(d,p)d and p(d,p)pn reactions as a tool for the study of the short range internal structure of the deuteron
In recent time the deuteron structure at short distances is often treated
from the point of view nonnucleonic degrees of freedom. In this paper the
measurements of T-odd polarization observables using tensor polarized deuteron
beam and polarized proton target or proton polarimeter are proposed to search
the quark configurations inside the deuteron.Comment: 12 pages, 8 Postscript figures, submitted in Phys.Atom.Nuc
АДСОРБЦИОННО-РЕОЛОГИЧЕСКИЕ СВОЙСТВА МОЧИ ЗДОРОВЫХ ЛЮДЕЙ
Розроблено і запропоновано для впровадження в нефрологічну практику новий метод обстеження хворих із захворюваннями нирок – визначення адсорбційно-реологічних властивостей сечі, який залежить від статі й віку людей. Фізико-хімічні параметри сечі (динамічний поверхневий натяг, в’язкоеластичність, поверхневі пружність та в’язкість, кут нахилу і фазовий кут тензіореограм) корелюють між собою та окремими показниками сироватки крові, а статевий диморфізм таких взаємовідношень стосується міжфазної активності при коротких часах існування поверхні та інтегрального адсорбційного коефіцієнту
Evaluation of the influence of combinations of drugs for general anesthesia on change of activity of stress-limiting and stress-realizing links on the clinical model of acute stress damage
When a person is in a state of anesthesia - sedation, the realization of the stress reaction is carried out through the mesocortical - limbic system, while performing intensive therapy outside sedation - through the amygdala and the hippocampus. In this regard, the response of the stress system under anesthesia and outside it will be different and, consequently, the evaluation of reactions during anesthesia is extremely interesting and necessary for targeted (individual) choice of combinations of drugs for anesthesia, depending on their effect on the links of the stress system. The more interesting is the response of the stress system in the conditions of the existing pathology, which in itself is accompanied by a stressful respons

Efficacy and Safety of Ascites Treatment in Liver Cirrhosis
Cirrhosis is one of the major health problems worldwide; and ascites is often its first and foremost manifestation. Despite the advances in modern hepatology, the presence of ascites is associated with a poor prognosis and high mortality. The aim of the study was to analyse data on the efficacy and safety of ascites treatment options, taking into account the pathophysiology of the condition. The analysis of literature and international guidelines on ascites management showed that cirrhotic ascites is treated with medication or surgery that interfere with pathogenetic mechanisms underlying the condition. Treatment of uncomplicated ascites depends on the severity of clinical manifestations. Patients with grade 1 ascites do not require treatment. Therapy for grade 2–3 ascites is aimed at reducing sodium intake and promoting its excretion with diuretics. The effect of diuretics should be assessed by daily monitoring of body weight. Close monitoring of serum creatinine and electrolyte levels is necessary to avoid severe electrolyte imbalance and mitigate the risk of diuretic-associated acute kidney injury. Another medical option to increase diuresis is the use of vasoconstrictors. Large volume paracentesis is the treatment of choice for patients with grade 3 ascites and refractory ascites. The most dangerous complication of paracentesis is circulatory dysfunction, which is prevented by limiting the volume of fluid removed to 5–6 liters per procedure and using plasma substitutes. If paracentesis is ineffective, new minimally invasive methods of treatment should be considered: transjugular intrahepatic portosystemic shunting and automated low-flow ascitic fluid removal system. However, given the poor prognosis, all patients with refractory ascites should be considered candidates for liver transplantation, which is currently the only effective treatment. The efficacy and safety of therapy may be enhanced by a personalised approach to choosing the treatment for ascites in cirrhosis, as well as further investigation of means to mitigate adverse reactions to medication and minimally invasive surgery
Aortic regurgitation: epidemiologic, etiologic, and pathophysiologic characteristics
The presented review concerns aortic regurgitation which occupies a significant place in the structure of valvular heart disease. The detailed anatomic and physiologic description of the aortic valve is provided. The characteristics of sinotubular, ventricular-aortic junctions, and virtual aortic annulus are presented. There are data about prevalence of aortic regurgitation on the basis of results of population studies, indicating the increase in incidence of aortic regurgitation among individuals older 70–74 years. The detailed etiologic structure of this valvular pathology is described with specifying of the most common causes of both aortic disease and aortic cusps alterations. In particular, there are some aortic diseases, resulting in acute aortic regurgitation, including acute aortic dissection and paravalvular regurgitation in incompetence of the prosthetic aortic valve; in chronic one – idiopathic dilation of the aortic root, inherited connective tissue dysplasias (Ehlers–Danlos, Marfan, and Loeys–Dietz syndromes), bicuspid aortic valve, aortitis of various origin, seronegative arthropathies (reactive, psoriatic arthritis, ankylosing spondylitis) etc. Infective endocarditis and traumatic exposure are commonly responsible for development of acute regurgitation due to aortic cusps abnormalities. Chronic aortic regurgitation as a consequence valve defects occurs in rheumatic heart disease, degenerative changes, congenital anomalies, systemic connective tissue diseases (systemic lupus erythematosus, rheumatoid arthritis), non-specific aortoarteritis, etc. The special attention is paid to pathophysiologic features of acute and chronic aortic regurgitation in the review. Acute aortic regurgitation is characterized by sudden increase in end-diastolic volume and due to the noncompliant left ventricle of normal size, it undergoes abrupt exposure a significant pre-load and after-load which results in decrease of left ventricle systolic function and stroke volume despite on relative preservation of contractile function of myocardium. In contrast to acute aortic regurgitation it is remarkable in its chronic form slow, progressive influence by increased overload of the left ventricle with possibility to adapt driven by its gradual dilation and hypertrophy
