Currently, one of the main economic policies of the Russian Federation in the field of food security is production of safe food and consumer protection. The aim of the research was to study the content of such toxic elements as Zn, Cd and Pb in milk and blood of cows. Experimental studies were carried out at stud farms Plemzavod Tayozhny LLC in Suhobuzimsky District and OPH Solyanskoe LLC in Rybinsk District, Krasnoyarsk Krai, Russian Federation. The milksamples were studied by atomic absorption method; the blood serum samples, by mass spectrometry. Blood serum samples were obtained by sedimentation of whole blood and retraction of the blood clot followed by centrifugation. The obtained data were processed by the method of variation statistics with the calculation of statistical indicators. The lowest contents of Zn, Cd and Pb were found in blood serum of the cows of OPH Solyanskoe LLC; it was 0.038, 0.001, and 0.002 mg/l, respectively. The milk samplescollected at Plemzavod Tayozhny LLCcontained less heavy metals than those collected at OPH Solyanskoe LLC: Zn by 2.069 mg/l, Cd by 0.01 mg/l, and Pb by 0.061 mg/l (P>0.999). When calculating the correlation coefficients, weak positive and negative correlationswere established between Zn and Pb content in blood and milk. The detected amounts of toxic elements did not exceed the maximum permissible concentrations, except for Pb content in milk sampled at OPH Solyanskoe LLC, which was higher than the standard content by 0.026 mg/l.

The aim and task of this study was to determine the presence of ochratoxin A (OTA) in blood serum, liver and kidneys of fattening swine, slaughtered regularly, originating from different areas of Serbia. During meat inspection on the slaughterhouse line samples of blood, kidney and liver per animal were randomly sampled (n=90) and analyzed by HPLC for ochratoxin A. Also, the presence of nephrotoxic (cadmium, lead, mercury and arsenic) elements in kidneys was carried out. Of the 90 liver samples, 26.6% contained OTA in the range of 0.22-14.5 ng/g, while the incidence of OTA in serum and kidney samples were very similar (31 and 33.3%, respectively). The analyses showed that serum samples were positive in the range of 0.22-221 ng/mL, while ochratoxin A concentrations in the kidney were between 0.17 and 52.5 ng/g. The mean distribution of OTA residue followed the pattern: serum>kidneys>liver (100>34>17), while in respect to occurrence it followed the pattern: kidneys>serum>liver (100>93.4>79.9). The results of this study showed that 2.2% of kidney sample had a content of ochratoxin A above the maximum permitted limit in Serbia of 10 ng/g. The results from this survey indicated that there was a low correlation between the OTA level in serum and liver as well as in the OTA level in kidney and liver (r=0.319 and 0.341, respectively) while the strongest correlation was found between the OTA level in serum and in kidney (r=0.973). The presence of mercury was found in 33.3% of kidney samples in the range of 0.005-0.055 mg/kg, while the presence of cadmium was found to a lesser degree (27.7%). The Hg concentrations in the kidney samples were lower than 0.10 mg/kg and did not exceed the guideline level established in Serbia, while concentration of cadmium in only one kidney sample was greater than 1.0 mg/kg, and exceeded the limit proposed by the Serbian Rule Book. The presence of arsenic was found only in one sample, while the presence of lead was not established. This study shows the presence of OTA in Serbian slaughtered pigs at levels comparable to those reported in other countries.

This paper provides a review of an emerging field in the food processing sector, referring to efficient and safe food supply chains, ’from farm to fork’, as enabled by Artificial Intelligence (AI). The field is of great significance from economic, food safety and public health points of views. The paper focuses on effective food production, food maintenance energy management and food retail packaging labeling control, using recent advances in machine learning. Appropriate deep neural architectures are adopted and used for this purpose, including Fully Convolutional Networks, Long Short-Term Memories and Recurrent Neural Networks, Auto-Encoders and Attention mechanisms, Latent Variable extraction and clustering, as well as Domain Adaptation. Three experimental studies are presented, illustrating the ability of these AI methodologies to produce state-of-the-art performance in the whole food supply chain. In particular, these concern: (i) predicting plant growth and tomato yield in greenhouses, thus matching food production to market needs and reducing food waste or food unavailability; (ii) optimizing energy consumption across large networks of food retail refrigeration systems, through optimal selection of systems that can be shut-down and through prediction of the respective food de-freezing times, during peaks of power demand load; (iii) optical recognition and verification of food consumption expiry date in automatic inspection of retail packaged food, thus ensuring safety of food and people’s health.

Aim: Although the levels of cardiac troponin I (cTnI) have proved to be a useful diagnostic biomarker of acute myocardial infarction, there are a wide variety of point-of-care (POC) analysers, which provide measurements of cTnI. The aim of this study was to compare the results obtained by the ADVIA Centaur ultra-assay cTnI assay (us-cTnI), ADVIA Centaur high-sensitive cTnI assay (hs-cTnI) and a POC high-sensitivity assay using PATHFAST. We also aimed to explore total turnaround time (TAT) for laboratory results using the POC PATHFAST analyser. Methods: Samples from 161 patients were taken. Of these samples, 129 were tested with all three assays (us-cTnI, hs-cTnI and PATHFAST), and 32 samples were tested on PATHFAST for the comparison of whole blood, serum and plasma. Results: Comparison of the POC testing methods in this study demonstrated that there are strong linear relationships between all three cTnI assays (us-cTnI, hs-cTnI and POC on PATHFAST). Furthermore, we also show there are strong linear relationships between the two high-sensitive cTnI assays (hs-cTnI and PATHFAST) for blood serum samples, as determined by Passing–Bablok regression analyses. In our comparison of our new data with our older study, the TAT went down. Conclusion: The timeliness of laboratory results is, in addition to accuracy and precision, one of the key indicators of laboratory performance, and at the same time has a significant impact on the course of the patient’s condition. It is therefore important that the laboratory strives to meet the expectations of clinicians regarding the time from the order to the result of the analysis.

Correlation coefficients between the results of political parties in the 2016 State Duma elections in the Russian Federation as a whole and in 26 regions, as well as in the elections of regional parliaments of 35 subjects of the Russian Federation in 2012–2015 were calculated. For the 2016 State Duma elections, data was used at all levels – regions, single-member electoral districts, TEC and PEC. It is noted that the “United Russia” correlations with all major parties are generally negative. A fairly high level of correlation is observed between the liberal parties. The main focus is on correlations between parliamentary opposition parties and parties with similar names. The correlation coefficients between the results of parties and candidates in the State Duma elections of 2011 and 2016 and the Presidential elections of 2012 and 2018 were also calculated, showing the stability of the geographical distribution of the electorate of the main parties. Regional differences in the nature of correlations between the main political parties are noted. It is assumed that correlations between parties reflect not so much their ideological closeness as the social closeness of their electorate. In this regard, it is noted that a positive correlation between the results of ideologically distant parties (“Yabloko” and the Communist party or “Yabloko” and “Rodina”) is associated with their reliance on the urban electorate and, perhaps, its most educated part. The reasons for voting for spoiler parties and the role of these parties in reducing the results of the main participants in the elections are discussed.

Out of 2942 blood serum samples from small ruminants of 10 flocks with a natural course of brucellosis caused by B. melitensis, 322 samples reacted with both antigens in the RID, of which 90 samples only with the O-PS M antigen (from B. melitensis), only with O-PS A-antigen (from B. abortus) reactive was not revealed. In healthy sheep immunized against brucellosis with the vaccine from strain 19 according to different schemes, only the O-PS M antigen was not found to react. Reaction with O-PS A- and M-antigens was observed in animals that were immunized twice subcutaneously at a dose of 40 billion mc. - after 2 months. after revaccination (60%), as well as in those reimmunized conjunctivally at a dose of 4 billion mc. according to the background of primary immunization subcutaneously at a dose of 40 billion mc. (10%) In animals immunized once or twice conjunctivally, reacting in RID with both antigens was not detected. Out of 2432 blood serum samples of small ruminants, 10 flocks with a brucellosis problem immunized against brucellosis with a vaccine from B.abortus strain 19 according to different schemes, 151 samples (6.2%) reacted positively with both O-PS antigens in RID with both O-PS antigens, of which only 86 samples (56.9%) reacted with O-PS M-antigen. The prevalence of indications of RID with O-PS M-antigen over RID with O-PS A-antigen (O-PS antigen made from Brucellae abortus) in small ruminants in one or another flock is characteristic of infection caused by brucellae melitensis at least in the absence, at least in the presence of the fact of immunization with a vaccine from the B. abortus 19 strain. RID with O-PS M-antigen is an objective indicator of epizootic danger and is able to differentiate brucellosis (B. melitensis) in small ruminants from vaccination-induced reactions (B. abortus 19).

Abstract. The Russian government's plan to reduce spending, plan not to extend the stimulus package and have the possibility of raising taxes by 2021 are steps to be taken. One of the objectives of the policy of the Russian Federation is to provide the conditions for complete economic development for all levels of society. This study aims to explain how one company in the Russian Federation in the city of Kazan is related to increasing corporate liquidity and risk management. This study uses quantitative analysis methods with liquidity analysis approaches and corporate risk assessment. The results of this study explain that a company in the Russian Federation in the city of Kazan can develop measures to increase corporate liquidity and risk management. The International Monetary Fund also warned that the Russian government's conservative economic policies could impede an immediate recovery - especially in the context of the second wave of infections that pushed the country's healthcare system to its limits.

Introduction. Toxic hepatitis (TH) is a complex and multifaceted disease, the development of which is mediated by a complex of biochemical and molecular genetic interactions. The current understanding of the pathogenesis of TH and, as a consequence, its treatment is based on standardization of the phenotype of the disease, often without taking into account metabolic disorders within the cells. Material and methods. experimental studies were performed on white outbred male rats weighing 200-220 g. A 50% solution of TCM was used as a toxicant. Biochemical studies were performed on a laboratory medical photometer “Stat Fax 3300” using clinical test kits and control materials manufactured by Vector-Best LLC. Liver tissue for histological examination was subjected to the standard histological procedure and paraffin embedding. Sections 5-7 μm thick were stained with hematoxylin-eosin. Gene expression analysis was performed using real-time PCR amplification on a RotorGene instrument (QIAGEN). Statistical processing of experimental data was performed using the Pearson correlation coefficient and one-way analysis of variance (ANOVA). The results were considered reliable at p <0.05. Results. As a result of the analysis of the correlation of the expression of the studied genes and the level of biochemical parameters, it was found that the correlation of the expression of the Nfe2l2 and Gstm1 genes was r = 0.812 (p = 0.0001). The dynamics of gene expression of Chek, Gstm1, Gstp1, Nfe2l2, had a negative correlation with the level of AST activity in blood serum. And the expression of the genes Chek, Gclc, Gstm1, Nfe2l2, Ripk, Sod1 with an index of ALT activity in the blood serum. After 72 hours, the expression of almost all of the studied genes became multidirectional. And the correlation between indices is often not determined. An analysis of the relationship between the level of cytolysis enzymes and the correlation level of the studied genes showed that after 72 hours the correlation was observed in the Gstm1, Hmox, and Sod1 genes with the levels of AST and ALT.
