Published: April 2020

Background
Several studies have investigated a possible association between respiratory infection and acute myocardial infarction (MI). As both influenza and pneumococcal infections are vaccine preventable, understanding the populations affected by virus-induced cardiovascular complications is important to guide public health and clinical practice.

Aim
This observational study aimed to quantify the association between laboratory-confirmed respiratory bacteria or virus infections and risk of first MI or stroke, by using self-controlled case series (SCCS) analysis of anonymised linked electronic Danish health records.

Methods
The SCCS method was used to determine the relative incidence of the first event of MI and stroke occurring within 28 days after laboratory-confirmed respiratory infections compared with the baseline time period.

Results
In the age and season adjusted analyses for first acute MI, the incidence ratios (IR) of a MI event occurring during the risk period were significantly elevated following a Streptococcus pneumoniae infection with values of 20.1, 11.0 and 4.9 during 1–3, 4–7 and 8–14 days, respectively and following respiratory virus infection with values of 15.2, 4.5 and 4.4 during 1–3, 8–14 and 15–28 days, respectively. The significantly elevated IRs for stroke following an S. pneumoniae infection were 25.5 and 6.3 during 1–3 and 8–14 days, respectively and following respiratory virus infection 8.3, 7.8 and 6.2 during 1–3, 4–7 and 8–14 days, respectively.

Conclusion
This study suggested a significant cardiovascular event triggering effect following infection with S. pneumoniae and respiratory viruses (mainly influenza), indicating the importance of protection against vaccine-preventable respiratory infections.

Published: April 2020

The article is devoted to the study of fire safety based on the calculation of fire risks in the objects of trade and cultural purpose in the event of a conditional fire. The conditions for safe evacuation of people in the event of a fire in the areas of the object, characterized by a significant concentration of people are substantiated. In both cases, a differential (field) fire model was used to calculate the dynamics of fire hazards. The formation of a three-dimensional computational domain was carried out in the Pyrosim program. In the article, the calculations of the dynamics of fire hazards were carried out, the measurements of which were carried out in seven conventionally accepted comparison points (locations of sensors-meters OFP). The estimated time to evacuate people is generally determined by simulating the movement of people before going outside. The choice of the method for determining the estimated time of evacuation was made taking into account the specific features of the space-planning solutions of the building, as well as the features of the contingent. As a model for calculating the evacuation time, an individual flow model of human traffic was used. Calculations for the considered scenarios of fire in the area of cinemas and in the area of the shopping hall showed that the individual fire risk for people is 8.94·10-8 and 2.63·10-7 year-1, respectively, that is, does not exceed the normative value. The results of the individual fire risk assessment can be used to confirm the compliance of the object of protection with fire safety requirements.

Published: April 2020

In this study peculiarities of distribution difficulties of Salicornia perennans Willd were studied, and ways to promote wide practical use as an alternative source of salt were outlined. Being a halophyte, Salicornia perennans Willd grows on salty soils of the Caspian region of Astrakhan. Not inferior in taste characteristics of edible salt, Salicornia contains a whole range of biologically active substances. Taking into account the wide prevalence of hypertension in the modern world, it is important to control the consumption of table salt. The study of plants of this kind is promising as a possible prevention of high blood pressure syndrome due to alternative substitution of table salt with Salicornia. Data on distribution are generalized and taxonomic difficulties of plants of the genus Salicornia impeding the generally accepted classification of the unique species are analyzed. The data obtained will allow unifying the further study of Salicornia perennans Willd growing in the Astrakhan region with the prospect of cultivation and creation on its basis of a food product that replaces edible salt

Published: April 2020

The article describes the effect of mineral fertilizers, a growth regulator, a growth stimulant and primary tillage methods on the yield and quality of winter wheat grain. A comparative analysis of the prevailing weather conditions by the amount of precipitation during the years of research with a long-term climatic norm and optimal values during the growing season of winter wheat to obtain maximum yield in the Saratov Trans-Volga region was carried out. As a result of research, it was found out that minimizing the main tillage in pure fallow crops for winter wheat reduces its yield by 10.5%. The maximum yield of winter wheat is provided by the combined processing (2.26 t/ha), which exceeds ploughing (control) by 3.2%. Deep subsurface processing did not provide a reliable increase in winter wheat productivity (+0.02 t/ha). The main tillage methods did not affect the protein content in the grain of winter wheat, and the amount of dry gluten decreased by 0.6% after minimal processing and 0.7% after subsoil tillage compared to the control. Spraying winter wheat crops with mineral fertilizers increased productivity by 3.7–8.8%, growth stimulator by 4.2%. The growth regulator (Giberelon) did not affect the productivity of winter wheat in the arid conditions of the Saratov Trans-Volga region. The maximum increase in protein and gluten was provided by mineral fertilizers Megamix No. 10 - 0.4; 1.7% and Mikrovit - 0.5; 1.6% and growth promoter GSN - 2004 - 0.5; 1.7%.

The use of plant growth stimulants and biological preparations is the most promising direction of the modern development of crop production. Currently, the assortment of substances that have a regulatory effect on plant growth and development is widely known. Favorable climatic conditions in the south of Russia make it possible to obtain high and stable crops of vegetables, including table beets, on irrigated soils.
For the first time in the light chestnut soil of the Astrakhan region, a study was conducted of the influence of foliar treatments with modern growth-promoting preparations and mineral fertilizers aimed at increasing the yield and quality of fruits of vegetable crops under drip irrigation
Studies on the cultivation of varieties and hybrids of beetroot were conducted during 2018-2019. on the lands of the FGBNU "PAFSC RAS". Based on the results of the field experiment, high biological yield indicators of 88.8 t / ha in the study were obtained from the Ethiopka cultivar using the variant using sheet treatment with Aminovit liquid complex fertilizer. The water consumption coefficient was 64.2 m³ / t. Moreover, the increase to the control option was +6.8 t / ha, marketable yield was 65.6 t / ha. According to the results of biochemical analysis, a low nitrate content was observed in the Ethiopka variety 1034.0 mg / kg in the variant using the Aminovit fertilizer. According to the sum of sugars of 8.5%, two varieties of Mulatka and Khutororyanka were distinguished using the variant with the use of the drug Aminofol Plus. It is necessary to highlight the following, that the use of growth-promoting drugs led to a significant reduction in nitrates relative to the control in the root crops of cultivars and hybrids of table beet being studied.

Published: April 2020

Seven lines of analogs with different color of leaves were created in sunflower by the backcross method of the recipient line of YuV-28B and gene donors controlling different variations in leaf color. A study of these lines at the Research Institute of Agriculture of the South-East region in 2017–2019, conducted as a competitive variety test, showed that most seed lines did not significantly differ in seed yield from the recipient line YuV-28B except for the L-4 line with olive color of the sheet, in which this indicator was lower than that of the recipient line. They were assessed analogous lines according to the phenological, morphological, crop-forming characteristics, as well as according to the quality of seeds and oil. All analogue lines had 100% shell of seeds and resistance to local races of broomrape and downy mildew. Most of the studied indicators of these lines correspond to the parameters of the source material, so they can be used in the selection of decorative sunflower.

Published: April 2020

A method for spectral analysis of the ratios of organic substances in a cell using the "Stains all" metachromatic luminescent dye (in its own modification) has been developed. This method is used to establish the ratio of nucleic acids and proteins in the integumentary epithelium of the mucous membrane and in the interlobular connective tissue of the submucosa tissue of the glandular stomach of chickens. Using the developed biophysical method, we studied the ratios of these organic substances in the glandular stomach of healthy and infected with E. coli chickens. The dynamics of the ratios of nucleic acids and proteins detected in the wall of the glandular stomach of the control group chicks fits into the picture of a moderate and uniform increase in the values of these indicators, corresponding to an age increase of the chickens. In chickens affected by Escherichiosis, a curve that reflects the dynamics of the ratios includes a three-fold increase in their values. The results obtained using the developed method indicate the possibility of using it to detect early metabolic changes in the glandular stomach of chickens before the appearance of a characteristic pathomorphological and clinical picture. Thus, this method can provide invaluable assistance in developing a fundamentally new approach in creation of modern technologies for the diagnosis, prevention and treatment of widespread disease Escherichiosis.

Published: April 2020

Salah satu upaya yang dapat dilakukan agar pemupukan fosfor (P) sesuai dengan kebutuhan tanaman cabai merah besar ialah dengan melakukan analisis tanah serta menentukan batas kritis P di tanah yang dihubungkan dengan produksi. Tujuan dari penelitian ini adalah menentukan batas kritis P di tanah untuk tanaman cabe merah besar di Pulau Jawa. Contoh tanah diambil dari 19 lokasi yang tersebar di Pulau Jawa. Analisis P tanah sebelum tanam dilakukan dengan tiga metode ekstraksi P yaitu Bray 1, Olsen, dan Mehlich III. Setelah analisis P tanah, bibit cabe merah besar ditanam dalam pot yang berisi 500 g tanah berat kering mutlak untuk tiap lokasi dan tiap lokasi mempunyai 4 dosis pemupukan. Dosis pemupukan P terdiri dari 0, 55, 110, dan 220 kg ha-1 P2O5. Sebagai pupuk dasar juga diberikan pupuk urea dan KCl masing-masing dengan dosis 110 kg ha-1 dan 180 kg ha-1. Tiap tanaman dipanen biomassanya setelah berumur 4 minggu setelah tanam. Pengaruh pupuk P terhadap parameter pertumbuhan tanaman dievaluasi menggunakan analisis ragam. Batas kritis P tanah ditetapkan dengan metode Cate dan Nelson. Hasil menunjukkan bahwa pemberian pupuk P berpengaruh nyata terhadap tinggi tanaman, bobot basah dan bobot kering tanaman. Pemupukan 220 kg ha-1 P2O5 memberikan respon tertinggi terhadap parameter pertumbuhan tanaman. Hasil uji korelasi menunjukkan bahwa ketiga metode ekstraksi P tersebut berkorelasi positif dan nyata dengan bobot kering tanaman. Metode ekstraksi Olsen memiliki korelasi tertinggi dengan bobot kering tanaman (r = 0.665). Batas kritis P dalam tanah untuk tanaman cabai merah besar di pulau Jawa berdasarkan metode ekstraksi Bray 1, Olsen, dan Mehlich III masing-masing ialah 15 ppm, 40 ppm, dan 50 ppm.
