A Study of Optical and Thermal Properties of (TeO_2-MoO_3-ZnO) Semiconducting Oxid Glass
No full textproduced a standard series of semiconducting tellurite oxide glasses containing vanadium and molybdenum oxides based on ), where X = 10, 15, 20, 25, 30 (mol-%) including quenching method. The influence of MoO3 on the glass transition temperature and photofission energy of this kind was analyzed. The thermal parameters of the used glasses, such as transition temperature (Tg) and thermal stability, were measured using the differential scanning calorimetry (DSC) method. Optical gap energy ( and end () were evaluated as a function of (ZnO) content in the glass. It was found that decreased with the increase of ZnO content, while ZnO content increased. Infrared and Raman spectroscopy, X-ray diffraction and scanning electron microscopy were examined and analyzed as a function of ZnO content in different compositions of such glasses

Modern Diagnostics in Various Forms of Chronic Heart Failure
No full textHeart failure (HF) is a clinical syndrome with typical symptoms and signs developing due to a violation of the structure and (or) function of the heart, leading to the inability of the heart to provide oxygen delivery at rest or under load in accordance with the needs of the body. This pathology is becoming one of the leading problems of modern medicine and is characterized by widespread prevalence, extremely unfavorable prognosis and high financial costs. The incidence of chronic heart failure (CHF) has been steadily increasing in recent years. According to the Framingham Study, in the United States, the number of patients with CHF among people over 45 years of age is 5 million people, and the number of patients increases by 400 thousand people annually [8, 9]. According to the data of the first Russian epidemiological study on HF EPOCH, the prevalence of CHF in the European part of the Russian Federation is 12.3% [6-8].
The prognosis for patients with CHF is extremely unfavorable: according to the Rochester and Rotterdam epidemiological studies, mortality in CHF of any functional class is 50% among men and 46% — among women over a 5-year period. The social significance of CHF is determined by large financial costs. Data from pharmaco-economic studies have shown that for the treatment of patients with CHF in countries Europe and the USA spend from 2 to 3% of the total health budget, which exceeds the cost of treating coronary heart disease and all oncological diseases combined. Moreover, 70-80% of the funds account for the payment of inpatient treatment of patients with CHF. The main strategic direction in the effective treatment of patients with CHF, improving their quality of life, and reducing mortality is to identify the early stages of the disease. Treatment of patients with the latent form of CHF, regardless of the degree of myocardial dysfunction, is the most promising approach to preventing the progression of CHF and early death of patients
Reproduction and Viability of Female Rat Offspring When Exposed To Ethanol
No full textThe work was carried out on female mongrel white rats (n=40) who were exposed to 10% ethanol solution during pregnancy, from one to five months before its onset, and on their viable offspring (n=220). Two periods of increase in the mortality rate of female rats were revealed: the first occurred in the 1st month of the experiment (mortality reached 25 %) and the second-in the 4th and 5th months of the experiment, when this indicator increased to 10 %. In rats, an increase in the duration of pregnancy was observed: the most significant prolongation of pregnancy (by 5 days) was revealed in females who were under the influence of ethanol for five months before its onset. The structure of total intrauterine mortality was dominated by preimplantation mortality, the highest rates of which were observed in rats treated with ethanol only during pregnancy, as well as for two and five months before its onset. The maximum post-implantation mortality was recorded in females exposed to alcohol for five months prior to pregnancy
