Resent scientific works demonstrate that population physical health depends on food quality. One of the important modern problems is lack of biologically active substances such as vitamins, ...antioxidants, and mineral substances in food. Many of them cannot be synthesized by the human body and must come with food. Tomato paste can be the source of the antioxidants necessary for the human body. The purpose of this work was to determine the content of carotenoids in tomato paste samples. Tomato paste contains a significant amount of carotenoids, mainly β-carotene and lycopene. As a result of experimental studies, the author determined the content of carotenoids, β-carotene and lycopene in tomato paste samples produced in Russia and abroad. It was found out that there is a direct proportion between the content of carotenoids and β-carotene: the higher the content of carotenoids, the higher the content of β-carotene. Proportion of β-carotene in all studied samples is a little more than 12% of the total amount of carotenoids. Consumption of concentrated tomato products by different age and social population groups in Russia will help improve food ration by means of providing β-carotene and lycopene according to the physiological requirements in nutrients

The work presents data on the effect of non-traditional powdered semi-finished products of plant origin: chokeberry, walnut partitions and sea buckthorn berries on the lifting power of baker's yeast. ...Various amounts of powdered semi-finished products of plant origin are introduced into the dough, directly at the stage of introducing the main components of the formulation, replacing them with some of the wheat flour. Studies have shown that the addition of small amounts of unconventional powdered plant-based semi-finished products (1 ... 5%) makes it possible to correct the lifting power of baking yeast, which, in consequence, affects the quality indicators of finished products. The paper presents a mathematical model of the change in the lift strength of baker's yeast, depending on the nature and amount of the powdered semi-finished product introduced.
Article contains information about new technologies of flour and bakery products on the basis of multicomponent structure products or the flour composite mixes executed from a flour of pumpkin and a ...thistle, a dry leaf of a stevia and dry lactulose, and also mixes from different types of grain, such as: corn, buckwheat, rice, millet.
This article considers the possibility of replacing part of the wheat flour with cereals made of buckwheat, rice and millet. The proposed solution will reduce the technological cycle of production of ...bakery products, which will reduce energy costs. On the other hand, the enterprises of the food industry will be able to reduce production residues and educate the consumer in the culture of rational nutrition. The authors considered the change in physical and chemical parameters of dough in the process of fermentation, proposed ways to optimize dough management.
This article focuses on the development of Russian discourses of civil society in academic and political contexts since 1991. In this discussion, the influence of changing Russian discourses and ...understandings of state-society relationships on the development of voluntary organizations (civil society organizations or CSOs) will be analysed. As this article demonstrates, the direct influence of the European Union and other international actors on Russian civil society has waned with the strengthening of Russian policies of nation-building and consolidation but remains a powerful background force. However, this study also provides evidence for more subtle forms of 'Europeanization' of civil society agendas, primarily through, but not limited to, pragmatic cooperation with EU partners. The most important area where this has taken place is in the definition of social agendas which have been neglected in Russia's post-Soviet transformation.
Abstract
Background
Nonvalvular atrial fibrillation (AF) is the most common sustained cardiac dysrhythmia and the most frequent cause of cardio-embolic stroke. It is well known that left atrial ...appendage thrombi (LAAT) are the source of most embolic strokes in patients with AF, and can be easily identified by transesophageal echocardiography (TEE).
Purpose
To determine additional LAAT predictors not included in the CHA2DS2-VASc score in patients with nonvalvular AF.
Methods
Retrospective study enrolled 636 patients with nonvalvular AF (400 males) aged 24–84 years (mean age 57.8±9.1), admitted to our Research Center in 2014–2017 for catheter ablation or electrical cardioversion. All patients had scheduled transthoracic echocardiography (TTE), as well as TEE performed to exclude LAAT. Four forms of cardiac geometry were revealed with the help of TTE according to Recommendations of ASE and EACI: normal geometry, concentric remodeling, eccentric hypertrophy and concentric hypertrophy.
Results
According to TEE results, LAAT (6.6%) was detected in 42 patients from 636. Patients with LAAT more often had persistent and permanent AF (assigned as “AF stability”), had bigger sizes and volumes of left and right cardiac chambers, lower left ventricular ejection fraction, more expressed LV hypertrophy and lower blood flow velocity in the LA appendage compared to patients without LAAT. Remodeling types also varied: less LAAT patients had normal cardiac geometry and more LAAT patients had LV eccentric hypertrophy. To analyze factors associated with AF, we used a multivariable logistic regression model, involving the potential independent, clinically relevant variables and echocardiographic parameters. Logistic regression analysis identified the latter three as independent predictors for LAAT (Table 1). According to ROC-analysis the quality of the received model was assessed as good: AUC=0.763 (p<0.01), sensitivity – 75.8%, specificity – 72.2%.

Conclusion
From risk factors, not included in the CHA2DS2-VASc score, in addition to such predictable values as AF stability and left atrial diameter, such predictor as eccentric left ventricular hypertrophy was revealed, which in our study was associated with more than a 4-fold increase in the risk of LAAT.
Wild plant species are of great interest as a source of pharmacologically valuable compounds but a great number of them are endemic and/or endangered ones. Modern plant biotechnology can provide ...reliable methods for their utilization without disturbing natural populations. In vitro culture methods for Rhodiola species are being intensively developed to include them into various biotechnological programmes. Aim. Development of a protocol for direct Rhodiola rosea L. plant regeneration from leaf explants. Methods. The leaves of R. rosea aseptically growing plants were used as the explants. Several variants of Murashige and Skoog (1962) agar-solidified culture medium supplemented with different combinations of auxins (1-naphthaleneacetic acid (NAA) and 2,4-dichlorophenoxyacetic acid (2,4-D)) and cytokinins (kinetin and 6-benzylaminopurine (BAP)) were estimated as potential regeneration-inducing media. Regeneration frequency was calculated as the percentage of leaves that produced shoots. Results. The use of MS medium supplemented with 2.5 mg/1 BAP and 1.0 mg/1 2,4-D allowed inducing shoot formation with 100% frequency. An increase in the 2,4-D content up to 2.5 mg/1 and decrease in BAP content to 1.0 mg/1 resulted in decreasing of the regeneration frequency to 62.5% . Regeneration frequency was 25% and 62%, respectively, on the media containing 1.0 mg/1 kinetin + 2.5 mg/1 2,4-D and 2.5 mg/1 kinetin + 1.0 mg/1 2,4-D. Conclusions. R. rosea leaf explants have demonstrated high regeneration capacity with the use of the studied combinations of plant growth regulators. MS medium supplemented with 2.5 mg/1 BAP and 1.0 mg/1 2,4-D allowed inducing shoot regeneration in leaf explants with the frequency of 100% . The frequency of regeneration was lower in the case of substitution of BAP for kinetin. The other types of morphogenesis (formation of adventitious roots and/or callus) were also observed.
The current state of most of Russia's territories is such that the development rates of specific regions remain low. This phenomenon does not allow for sustainable long-term economic security. ...Therefore, it is necessary to develop measures to determine the financial stability of the individual regions and territories of the country for the purposes of their development under current conditions. In this sense, the real problem is to determine the financial indicators to assess the economic security of rural areas. This can be achieved through the formation of a scientifically based action algorithm aimed at improving the situation in rural areas. The research topic is the formation of a system to identify financial indicators in the evaluation of the economic security of rural areas. The theoretical and practical significance of solving problems related to the achievement of sustainable development in rural areas determined the choice of goals, objectives, object and theme of this study. Based on the above, the object of the study is the municipal budget and agricultural enterprises as the basis for the development of rural areas. The purpose of the study is to establish the methodology for evaluating financial security in rural areas as a financial management instrument at the municipal level. The following tasks were implemented in the course of the study: selection of financial indicators based on official and expert sources; Foundation of the mathematical apparatus to calculate the comprehensive and private indicators of the financial security of the territory using the principles of qualimetry (the science of measuring quality). The proposed methodology allows to systematize the financial and economic indicators, it serves as the main calculation of the financial and economic security of the Udmurt Republic; the methodology can also be applied to other rural areas of the country.
