The twenty-first century is an era of multilanguage personalities and polyglots. The interaction of peoples around the world, their desire for mutual understanding, the international position in the field of education on the intensification of learning languages, wide access to the educational space of the world community-all this demonstrates the importance of multilanguage competence in the modern world. By creating a solid foundation in the field of professional training in foreign languages, we form the ability to use them as a means of intercultural communication.

The aims of study– a development of biochemical algorithms of early diagnostic of severity of CHF in patients with DM and IHD and analyze interrelationships between plasma redox-potential, as a marker of progressive of tissues metabolic remodeling and cardiac hypertrophy and markers of progressive of DM, neurohumoral markers of severity of CHF, and frequency of heart rhythm disturbances.Materials and methods.172 patients, male / female (45–65 years), with diagnosis of DM (metabolic decompensation of carbohydrate metabolism, HbА1c – 7.4 ± 1.9 %) during 3–15 years, accompanied with IHD and symptoms of CHF I–IV NYHA functional class (FC). The first point of investigation was examined markers of DM progression HbА1c, changes in FC of HCHF and evidenced prognostic neurohumoral markers of myocardial dysfunction NT-proBNP, and as a second (surrogate) point – changes in redox-potential NAD / NADH and total pool of pyridine nucleotides.Results.Mean NYHA FC CHF in cohort of DM patients and IHD was 2.4 ± 1.2, mean point of CHF estimated by scale of symptoms of CHF was 6.7 ± 0.6, mean distance in 6-minute test was 212 ± 26 m, concentration of neurohumoral markers of myocardial dysfunction NT-proBNP 178 ± 26 fmol / l at the level of HbA1c = 7.8 ± 1.0 %, mean redox-potential of plasma, НАД / НАДН, 0.71 ± 0.06 and total pool of pyridine nucleotide 15.1 ± 1.2 μmol / mg protein of plasma. For the first time was shown that changes in redox-potential and sum of pyridine nucleotide coupled with severity of CHF (FC of CHF), eliminated the correlation between NAD / NADH and HbA1c (r = –0.79, p<0.001), and NTproBNP (r = –0.73; р <0.001), and increasing of tumor necrosis factor alpha (TNF-α, r = –0.73; р <0.001). Simultaneously maintenance decreasing of NAD / NADH and sum of pyridine nucleotide in plasma of patients with DM and IHD coupled with increasing of daily mean values of paired supraventricular and ventricular extrasystoles.Conclusions.In patients with DM and CHF with left ventricular dysfunction the decreasing of redox-potential level in plasma could be recommended as a markers of increasing of metabolic remodeling and progression of cardiac hypertrophy.

Aim. To study the role of plasma redox potential reduction in the development of endothelial dysfunction (ED) among patients with chronic heart failure (CHF) and to investigate the potential of its pharmacological correction. Material and methods. This randomised cohort study included 73 patients with CHF, due to coronary heart disease (CHD) and arterial hypertension. Mean age of the participants was 59,2±5,9 years. Functional Class (FC) I CHF was registered in 9 patients, FC II CHF in 21, FC III CHF in 23, and FC IV CHF in 11. After the baseline examination, all participants were randomised into two groups. The main group (MG) received standard therapy plus adenocin (2 ampoules in 70 ml 5% glucose, intravenously) for 10 days. Results. For the first time, the dynamics of redox potential and total pyridine nucleotide levels was assessed in relation to the FC of ischemic CHF. Redox potential reduction preceded the changes in the total pyridine nucleotide levels. In contrast to standard therapy, adenocin increased plasma redox potential and endothelial growth factor levels, while reducing endothelin-1 concentrations and NADPH oxidase activity. Conclusion. Combination therapy with adenocin – a unique medication of reduced NAD form, cardiac glycoside, and inosine, in contrast to standard treatment, significantly increased cellular redox potential in CHF, which could play an important role in angiogenesis stimulation and reverse endothelial remodelling.

The article presents the results of a study of the enzymatic hydrolysis of barley malt sprouts by cellulolytic enzymes. The influence of the process parameters (temperature, substrate concentration, concentration of the enzyme preparation, duration of the process) on the output of dry substances in the hydrolysate is shown. The results of the experiments were presented by a mathematical model of the process and graphically-in the form of surface projections reflecting the mutual influence of each possible pair of factors on the dry matter content in the hydrolysate. It is found that all the studied factors have an effect on the accumulation of dry substances in the hydrolysate. As a result of optimization the parameters of the enzymatic hydrolysis process, the following parameter values were obtained: temperature - 50 ˚С, duration of enzymatic hydrolysis-89 min, substrate concentration - 0.37 (hydromodule 1:10), concentration of the enzyme preparation - 0.05 %.
