Chronic respiratory pathology and life quality of the adolescents living in industrial centers

At present the pathology of laryngeal and respiratory organs is known to prevail in the structure of the child and adolescent morbidity in the industrial centers of the northern and eastern regions of the country and their proportion reaches 70 %. The disease symptoms of the respiratory tracts (the obstacle nose, discomfort and throat tickling as well as the hoarseness) and especially their complications may lead to the decrease in the life quality of children and adolescents. Taking into account that at present time it is impossible to remove technogenic air pollution totally, the complex studies on revealing the unfavorable factors, which may influence the organisms of the children and adolescents, are known to be the prior task of the preventive medicine. The aim of the study was to examine the frequency chronic respiratory pathology and influence on the adolescents life quality of industrial centers of Irkutsk region with different levels of technogenic pollution. 410 adolescents (14-17 years) for a long time living in the regions with the different air pollution levels air with the developed oil-chemical and industries were examined. The differences in the structure of chronic respiratory pathology were revealed in the examined adolescents: under conditions of the air pollution with a complex of chemical compounds with a high Hasard Index (HI = 17) the respiratory diseases prevail, and with the medium level (HI = 3,6) the nasal diseases prevail. It was found that that about 12,6 % of the morbidity variability in the category of the respiratory organs, in particular the throat pathology in the teenagers may be correlated with the air pollution. The more significant factors of forming the chronic respiratory pathology were found to be the health state, characterized by the laboratory indices (common microbial number of the nasal cavity and the pharynx; activity of lysocyme); chemical inhalation exposure; the work of the parents under harmful conditions during the period before child birth. The study results may be considered as the basis for the optimization of the approaches to the diagnostics and prevention of the respiratory pathology of adolescents

Assessment of quality and safety of pork treated with low-temperature atmospheric-pressure plasma

It is known that processing methods ensuring partial or full microbial inactivation are quite limited. Therefore, it is of great interest to develop technique and technologies allowing the effective action on microorganisms without a significant influence on product properties. The use of cold plasma can be one of the promising methods of meat product treatment by cold sterilization. The present work examines a possibility of chilled meat treatment with low-temperature atmospheric-pressure plasma to increase its stability to microbial spoilage and extend shelf life. To obtain low temperature plasma, the equipment developed by the designing department “Plasmamed” was used. Chilled meat was treated with low-temperature atmospheric-pressure argon plasma for 5, 10, 20 and 30 min. Samples were stored at a temperature of 2–4 °C for 10 days. Organoleptic indices, moisture weight fraction, changes in pH and water activity were analyzed before treatment and during storage. Sanitary microbiological analyses were carried out by the following indicators: quantity of mesophilic aerobic and facultative anaerobic microorganisms (QMAFAnM), the presence and quantity of coliforms, Salmonella, Escherichia coli, Listeria monocytogenes, Proteus. It was shown that meat cold treatment with argon plasma inhibited the development of mesophilic microorganisms. The colony forming units detected in the samples after ten days of storage were determined by the duration of exposure to plasma. It was proved that meat treatment for 15 and 30 min had the bactericidal effect and facilitated an improvement in meat color during storage. The organoleptic indices of the samples treated with plasma corresponded to the requirements of standards and approved consumer characteristics

An effect of anti-stress feed additives on broiler productivity and meat quality

The paper presents the study on an impact of feed additives Peak anti-stress and SPAO (SPAO-complex) with different lithium content on meat productivity and meat quality of broiler chickens. The feed additives exert a pronounced metabolic effect, have adaptogen properties and allow forming a mechanism that facilitates compensation of the expenditure of the body, which significantly increases upon stress development. It was established that the average daily gain of the broiler chickens increased by 1.8% and 4.3% on the background of using SPAO-complex and Peak anti-stress, respectively, compared to the broiler chickens that did not receive the feed additives in the daily diet. It was shown that addition of feed additives with lithium into a diet led to an improvement of the indices of broiler meat productivity and meat quality: a level of yield of the carcasses of the 1st category increased up to 56.2–79.1%, high organoleptic indices of meat were ensured, the protein content in white and red chicken meat increased and functional-technological properties of minced meat improved. The use of feed additives ensured profitability of industrial poultry production; the highest indices of profitability were established upon introduction of the feed additive Peak anti-stress into a diet — up to 8.67 rubles per each ruble of expenses. The obtained results of the study should be taken into consideration in the technological processes when raising broiler chickens

Studies of the molecular mechanisms of grape (<i>Vitis vinifera</i> L.) resistance to low-temperature stress

Abiotic stressors are the main factors limiting the expansion of territories occupied by grape plantations. Industrial viticulture is concentrated in the south of Russia and is limited by climatic factors that do not allow large-scale production in other regions of the country.The present review considers the molecular mechanisms of resistance to low-temperature stress and discusses the role of the main genes determining the ability of plants to survive and acclimatize during a critical temperature drop.One of the most studied ways of responding to cold stress is the interaction of genes in the ICE-CBF-COR cascade, however, a more accurate understanding of the genes responsible for resistance to abiotic environments specifically in grapes requires additional studies. A series of studies of functions of transcription factors and related genes of response to low-temperature stress in various species (Arabidopsis, tea, orange, blueberry, and grape) have identified four main regulons: 1) CBF/DREB, 2) NAC/ZF-HD, 3) AREB/ABF, and 4) MYC/MYB. Studies have demonstrated the function of the HOS1 gene, which negatively regulates the work of ICE1 (a key resistance factor). The review considers candidate genes in various species of annual plants: ICE1, HOS1, SIZ1, MPK3, MPK6, in families of genes: CBF, COR, RD 29A, LTI78, ERD, LEA; DREB1, ADREB1B; WRKY10, and in perennial crops: ICE1, CBF1, HSP70, SUS1, GST, DHN1, BMY5, BHLH102, GR-RBP3, ICE1, GOLS1, GOLS3; CBF; COR27, RD29B, NCED1, ERF105, ZAT10, SAP15, WRKY3, and LEA.Until recently, interspecific hybridization was the leading method for obtaining cold-resistant grape varieties. The main donor of resistance is V. аmurensis Rupr. Recently, the research focused on the genetic basis of grape resistance to low temperatures is actively developing. For instance, a comparative analysis of the transcriptomes of two species contrasting in this trait, i.e. V. amurensis, resistant to low temperatures, and V. vinifera L. with low cold resistance, made it possible to identify three additional candidate genes with an increased expression in response to exposure to low temperatures, namely CBF3, ERF105 and ZAT10. At the same time, the practical application of modern accelerated breeding methods requires the identification of all additional key genes responsible for resistance to low-temperature stress. The components from the cascade of sequentially expressing ICE–CBF–COR genes (ICE1, ICE2, CBF1, CBF2, CBF3, and HOS1) have been selected as candidate genes

Natural Afforestation on Abandoned Agricultural Lands during Post-Soviet Period: A Comparative Landsat Data Analysis of Bordering Regions in Russia and Belarus

Remote monitoring of natural afforestation processes on abandoned agricultural lands is crucial for assessments and predictions of forest cover dynamics, biodiversity, ecosystem functions and services. In this work, we built on the general approach of combining satellite and field data for forest mapping and developed a simple and robust method for afforestation dynamics assessment. This method is based on Landsat imagery and index-based thresholding and specifically targets suitability for limited field data. We demonstrated method’s details and performance by conducting a case study for two bordering districts of Rudnya (Smolensk region, Russia) and Liozno (Vitebsk region, Belarus). This study area was selected because of the striking differences in the development of the agrarian sectors of these countries during the post-Soviet period (1991-present day). We used Landsat data to generate a consistent time series of five-year cloud-free multispectral composite images for the 1985–2020 period via the Google Earth Engine. Three spectral indices, each specifically designed for either forest, water or bare soil identification, were used for forest cover and arable land mapping. Threshold values for indices classification were both determined and verified based on field data and additional samples obtained by visual interpretation of very high-resolution satellite imagery. The developed approach was applied over the full Landsat time series to quantify 35-year afforestation dynamics over the study area. About 32% of initial arable lands and grasslands in the Russian district were afforested by the end of considered period, while the agricultural lands in Belarus’ district decreased only by around 5%. Obtained results are in the good agreement with the previous studies dedicated to the agricultural lands abandonment in the Eastern Europe region. The proposed method could be further developed into a general universally applicable technique for forest cover mapping in different growing conditions at local and regional spatial levels

Silicoarthritis: issues of early diagnosis, prevention

Background. The severity of the course of silicosis is aggravated by the addition of complications; one of the serious and rare complication of silicosis is silicoarthritis or Kaplan’s syndrome (KS), which accounts for 0.1-0.6% of all cases of silicosis. Silicoarthritis significantly reduces the quality of the life of patients and leads to early and persistent disability.Aim. To establish the most significant methods of diagnosing silicoarthritis for early detection of the disease and prevention of complications.Materials and methods. The article presents clinical cases of silicosis and its rare complication - SC. The basis for the diagnosis of this pathology is X-ray, immunological and functional methods.Results. In patients with more than 5 years of experience exposed to aerosols of fibrogenic action, crystalline silicon dioxide, with an excess of the MPC level from 2.3 to 4 times on the basis of MSCT of the lungs, during which multiple polymorphic foci with a diameter of 2 up to 10 mm, partly merging with each other into peribronchovascular couplings, as well as perifocal areas of reduced airiness like ground glass and thickening of the axial interstitium, a diagnosis of late silicosis, stage 2 nodular form was established, the diagnosis was confirmed by biopsy data. In dynamics, after 5 years, arthralgic complaints joined. On the basis of immunological (increased TNF-alpha, IL-1b), X-ray examination (osteoarthritis of the distal and proximal interphalangeal, wrist, metatarsophalangeal joints), the diagnosis was clarified as Silicoarthritis: Kaplan’s syndrome.Conclusion. Diagnosis of silicosis and its complications at the preclinical stage in workers who have been in contact with silica dust for 5 years or more should include: MSCT of the lungs, determination of TNF-alpha, IL-1b, rheumatoid factor, and a study of respiratory function
