Phenolic Compounds of the Medicinal Plants in an Anthropogenically Transformed Environment.

In this article, the impact of an anthropogenically transformed environment on the content of pharmaceutically valuable biologically active compounds in medicinal plants is analyzed. The studied biologically active substances included phenolic compounds (flavonoids, anthocyanins, tannins, and phenolic acids). The number of transmissible forms of heavy metals (HMs), including cadmium, lead, and mercury, were discharged from factories that are present in the soil.

[The combined use of peptide bioregulators and self-massage in order to improve the psychophysiological state and increase the professional performance of the elderly.].

The development of modern society is characterized by an increase in the volume and changing forms of information presentation. In the works of Russian and foreign gerontologists, it is noted that the perception and analysis of the flow of relevant data today causes difficulties for a significant part of citizens of older age groups, which is due, among other things, to the deterioration of their psychophysiological state. The lack of the ability to use the necessary information negatively affects the quality of life, the level of social adaptation and professional competence.

[Accelerated aging as a risk of the education digitalization: possibilities for prevention.].

The work is devoted to the analysis of the education digitalization negative effects and the possibilities of their prevention consideration. The urgency of this problem in the modern conditions of combating the pandemic of the new coronavirus infection and moving a significant part of education and leisure to the virtual space is noted. Against the background of a deficit in physical activity and an increase in the information consumption duration, the participants in the experiment showed a significant increase in the frequency of mental and physical maladjustment symptoms occurrence, a decrease in performance indicators and a deterioration in the biological age parameters.

[The role of functional and instrumental research methods in the diagnosis and control of chronic obstructive pulmonary disease in the elderly.].

In more than 500 elderly patients with COPD, the frequency of spiral computed tomography (SCT) of the lungs and echo-CG of the heart was evaluated for diagnostic purposes and to monitor the course of the disease. The study showed that despite the high clinical significance of the FEV1 indicator (the volume of forced exhalation in the first second), the indicator itself is extremely non-specific when diagnosing COPD in elderly patients. The high specificity of lung CT makes it necessary to use this diagnostic method in elderly patients to detect morphological changes in the lungs in the presence of clinical signs of bronchial obstruction and negative spirometry data.

[Working ability of elderly university teachers under the combined influence of breathing exercises and peptide bioregulator «Cortexin».].

The two-week use of special breathing exercises in combination with the Cortexin peptide bioregulator optimizes the functional state and increases the professional performance of older teachers more effectively compared to the single use of a pharmacological preparation. The maximum effect is noted immediately after the end of the course use of special breathing exercises and the peptide bioregulator and lasts for two months. The results obtained open up prospects for the use of breathing exercises to enhance and prolong the nootropic drugs and antihypoxants antistress and geroprotective effects.

[The influence of self-massage combined with drug Noopept on the professional performance of teachers older.].

It is shown that the two-week use of self-massage of the head and neck in combination with the pharmacological drug Noopept improves the functional state and increases the professional performance of elderly teachers compared to single use of nootropic drug. The greatest increase in the functional state and professional performance was noted immediately after the course of self-massage of the head and neck in combination with the pharmacological drug Noopept. The combined effect of self-massage and nootropic drug on the functional state and professional performance indicators are maintained for 1-2 months, and by the end of the third month they are approaching the initial values.

Taenia sp. in human burial from Kan River, East Siberia.

We present an arhaeoparasitological analysis of a unique burial from the Neftprovod II burial ground in East Siberia, which dated from the Bronze Age. Analysis of a sediment sample from the sacral region of the pelvis revealed the presence of Taenia sp. eggs.

[The cytogenetic diagnostic of chromosome anomalies under non-developing pregnancy.].

The purpose of the study is to analyze qualitative and quantitative characteristics of chromosome anomalies in abortus under undeveloped pregnancy. The cytogenetic analysis was implemented concerning embryonic material obtained after artificial abortion of undeveloped pregnancy in 57 women. The percentage of abnormal karyotypes made up to 67.

[Analysis of some parameters of biological age and adaptation possibilities of workers of locomotive brigades].

The unfavorable factors of professional work of workers of locomotive brigades influence on speed of aging and adaptation possibilities of an organism. Analysis of the data obtained confirms the positive use of the peptide bioregulator Pinealon in maintenance the professional reliability of workers of locomotive brigades. Workers of locomotive brigades used preparation during two weeks (1 capsule containing 100 mkg of Pinealon 2 times a day).

Light-induced changes of the refractive indices in a colloid of gold nanoparticles in a nematic liquid crystal.

It was shown that irradiation of a nematic liquid crystal doped with metal nanoparticles in the visible near the plasmon resonance band led to strong thermal changes of the refractive indices. The effect was studied by recording of dynamic optical gratings in the colloid. Nanoparticles "worked" as effective nano-heaters in a matrix causing the order parameter decrease around the particles.

[Use of erythropoietin in the treatment of patients with oncohematological diseases].

The role of erythropoietin in the development of anemia in patients with oncohematological diseases has been discussed. Efficacy of use of erythropoietin in patients with oncohematological diseases was analyzed. Features of use, contraindication and adverse reactions have been discussed.

[Ground-based speleo-climatic wards and the experience with their use in bronchial asthma].

Ambient air in ground wards made to contain natural potassium-sodium salt is close in characteristics to the atmosphere of underground wards but has a number of specificities: daily fluctuations of concentrations of light aeroions and aerosol particles, elevated concentration of light aeroions concentration, low radiation background, minimal bacterial contamination. The stay in ground wards brings great benefit for patients with bronchial asthma. Ground speleo-climatic wards are perspective in nonpharmacological treatment of patients with allergic respiratory diseases.
