Epidemic situation on enzootic bovine leukosis in public and individual farms in the Republic of Dagestan
Authors: Mustafayev A. R. 
Published: July 2021

The spread of the bovine leukemia virus impedes the development of livestock production and causes considerable losses. Despite the measures implemented, the problem of bovine leukosis eradication remains relevant in different regions of Russia. The article presents data on distribution of enzootic bovine leukosis in the Republic of Dagestan. Over the past five years, the lowest level (1.02%) of leukemia virus infection in cattle in the Republic was recorded in 2020. Laboratory tests for bovine leukosis were carried out in 41 raions and 7 municipal districts: no disease was diagnosed in 12 raions and 4 municipal districts, and the animal seropositivity index in the rest of areas was less than 1%. A high level of animal infection with the leukemia virus was recorded in the following raions: Dakhadaevsky (10.3%), Shamilsky (7.9%), Tarumovsky (3.1%), Kizlyarsky (2.3%), Babayurtovsky (2.2%), as well as in the town of Yuzhno-Sukhokumsk (3.8%). In other districts, the parameter’s values ranged from 1 to 2%. In total, 524,930 animal sera samples were serologically tested using the immunodiffusion method, out of which 5,362 samples were seropositive in 2020. 1,265 sera samples from animals infected with the leukemia virus were tested using the hematological method, 251 animals (19.8%) with persistent leukocytosis were identified, which is the average for the past years. Comparative analysis of the morbidity rate for bovine leukemia virus in farms of different categories showed that in public farms of the republic the percentage of infection level was higher (3.3%) than in the individual sector (0.7%). Thus, bovine leukemia infection level in the republic tends to decrease. Nevertheless, the infection and morbidity rates in cattle remain high in some raions and municipal districts, in particular, in the public sector.

Published: July 2021

The due performance by the veterinary service of its assigned functions depends largely on the amount of funding provided for different aspects and types of its activities. The paper presents analysis results for 13 main funded activities of veterinary services in 85 Subjects of the Russian Federation in 2019. All the funded activities were reviewed in relation to three funding sources: the federal budget, the budget of a Russian Federation Subject and extrabudgetary sources. The paper examines funding levels of the Russian Federation Subjects’ veterinary services (against actual funding requirements) with respect to each object of expenditure and each funding source; besides, the share of each funding source in overall funding of the veterinary service of the country on the whole and of certain types of its activities was determined. In 2019, overall funding of the veterinary service of the country amounted to about 49.5 billion rubles which made up 96% of funding requirements for this period. The major sources of funding were the budgets of the Russian Federation Subjects (56.3%) and veterinary services’ own extrabudgetary resources (43.2%). Only 0.5% of all the funds received by the state veterinary service of the Russian Federation were allocated from the federal budget. The following 4 out of 13 analyzed aspects of activities of the Subjects’ veterinary services were fully funded: staff salaries, anti-epidemic activities, the purchase of reagents and test systems, the implementation of monitoring and screening programmes at the Subject level for contagious animal disease control. The funding levels for other activities of the country’s veterinary service were from 9% (accreditation of veterinary laboratories and maintenance of accreditation) to 87% (the implementation of regional monitoring of food product, raw material, animal product quality and safety; animal health awareness-raising and information activities).

Published: July 2021

Cultivation of cut flowers is a new agricultural sector in Ethiopia, which currently generates a high amount of income for the country's developments. Despite its significant contribution to economic developments; many issues were raised from communities and environmentalists concerning its environmental performance. Based on this issue the study assesses cradle to gate of cut flower production in the Wolmera district. The main objective of the study was environmental performance evaluation of flower farms in Wolmera district, Oromia regional state, Ethiopia related to operational activities throughout entire life cycles of cut flower production. In this study, primary and secondary data were collected using ISO 14031 standard structured with LCA tool methodology. Data were collected by inventory using an on-site data collection system from its sources. Based on data collected GHG (CO2, N2O, CH4 & NH3) emissions to the atmosphere were evaluated by using an inter-governmental panel on climatic changes (IPCC 2006) for inventory data and eutrophication & acidification estimated from data tested at laboratory levels. Similarly, the study also assesses banned chemicals used in the farms through inventory data assessment, and about 156 chemicals applied in the farms were collected to screen out those banned chemicals used and the two most extremely hazardous chemicals (Impulse & Meltatix) banned by WHO identified in the study. As it understood from a general assessment of all flower farms; all of them haven't EIA document established before construction in the district and production started with having less attention for EHPEA code of conducts in the flower farms which faces the environments for high impacts by emission emitted from flower farms in the district as a whole.

Objective — to study the state of iodine supply in children with chronic gastroduodenal pathology.
Materials and methods. The study included 23 children with chronic gastroduodenitis: 13 girls (56 %) and 10 boys (43.5 %) aged 8 to 18 years. The control group consisted of 11 children matched in age and sex. All patients underwent endoscopic examination of the upper digestive tract. H. pylori infection was tested with a rapid urease breathing test «Helik‑test». All children underwent determination of iodine level in single portions of urine using the cerium‑arsenite method Sandell‑Koltoff modified by Dunn, with the following calculation of the median.
Results. The frequency of iodine deficiency in children with chronic gastroduodenitis was 60.9 ± 10.2 %, which significantly exceeded this parameter in the control group (8.7 ± 8.6 %; p < 0.01). A mild degree of iodine deficiency was noted in 43.5 ± 10.3 % of patients, which was also significantly higher than in the control group (9.09 ± 8.6 %; p < 0.05). Moderate iodine deficiency was observed only in children of the main group (21.7 ± 8.5 %). Severe iodine deficiency in the study was not found among all children. The median ioduria in patients was 81.9 mg/l, which was significantly lower than in children in control group (183.7 mg/l; p < 0.05). Analysis of ioduria level, taking into consideration the endoscopic picture of gastrointestinal tract lesions, showed that both in frequency (p < 0.05) and median (p < 0.05), children with a more severe inflammation of the gastric mucosa and duodenum had the worst indices of iodine supply. In children infected with H. pylori iodine deficiency was observed significantly more often (p < 0.05), the median ioduria was significantly lower (p < 0.05) than in uninfected children.
Conclusions. In children with chronic gastroduodenal pathology, a significant frequency of iodine deficiency is revealed, which increases with the severity of inflammatory changes in the mucous membrane and the presence of H. pylori infection. Determination of the state of iodine supply in children with digestive tract pathology is advisable to prevent the development of concomitant diseases, primarily thyroid dysfunction.

Published: July 2021

The authors emphasize the prospects of using fecal microbiota (FM) transplantation from a healthy person as a modulator for restoring disturbed intestinal microbiota. The presented results from experimental studies on animals showed the FMT effects at metabolic syndrome. Thus, microbiota transplantation from thin subjects reduced the dysfunction of glucose metabolism, increased the relative abundance of Akkermansia, Muscispirillum, Oscillospira and Ruminococcus. It resulted in the decrease of body weight, serum levels of alanine aminotransferase and aspartate aminotransferase, endotoxin, reduced steatohepatitis intensity (the average liver NAS score decreased due to decrease of the levels of intrahepatic triglycerides, cholesterol, the balance of pro‑ and anti‑inflammatory cytokines normalized). Thus, the recipient was successful in modelling the «metabolically favourable» microbiota profile. However, human studies did not show such significant results. Only a part of the authors noted that FMT from skinny donors temporarily increased peripheral insulin sensitivity and the level of butyrate‑producing intestinal bacteria (Eubacterium hallii or Roseburia intestinalis), the level of secondary bile acids (lithocholic in blood plasma and feces, isolitocholic and deoxycholic in feces), propionate and butyrate in feces, and also reduces the levels of g‑glutamyl transpeptidase and alanine aminotransferase and increases the number of Ruminococcus, Faecalibacterium and Prevotella copri. Other researchers did not note statistically significant improvements in insulin sensitivity, changes in the degree of steatosis and liver fibrosis, and most authors did not find changes in BMI after FMT. Summarizing the available data showed that although FMT is a potential therapeutic strategy for obesity (confirmed to be associated with improved insulin sensitivity at 6 weeks), the quality of the evidence is low, rhus higher number of investigations are needed to study the effects of FMT on the long‑term clinical endpoints, determining the optimal dosage, route of delivery, duration of therapy, stool preparation, and donor selection to maximize the therapeutic effect of FMT.

Published: July 2021

The human gastrointestinal tract is inhabited by almost 100 trillion bacteria, more than 90 % of which belong to the phylotypes Bacteroidetes and Firmicutes. This is about the same as the entire human body contains. The complex network of microbes that inhabit the body regulates its health and is supported by a balance of genetic and dietary factors. For the proper existence and survival of microbial populations in the intestine, a strictly regulated intestinal barrier is required, the violation of which can lead to the systemic spread of microbes and their penetration into the portal bloodstream. The intestinal barrier includes physical, immunological and microbial components. When any aspect of the gut barrier is not working, even bacteria that normally promote health can wreak havoc and contribute to disease and damage. It is known that changes in the intestinal barrier, intestinal permeability, and gut microbiome (GM) are associated with many diseases, including liver pathology. To understand how GM changes can lead to liver disease, a comprehensive understanding of the physiology of the intestinal barrier is required. Because of the close anatomical and physiological relationship between the gut and the liver, there has been a lot of research into how changes in one organ affect another. This review considers the main components of the intestinal barrier and the mechanisms of its pathological changes, including increased intestinal permeability, as well as GM disorders and their role in the pathogenesis of liver diseases, such as alcoholic liver disease, non‑alcoholic fatty liver disease, drug‑induced liver damage, liver cirrhosis. and its complications. Existing and promising therapeutic strategies for modifying GM and the intestinal barrier, which can be used in the treatment of hepatic pathology, are also considered.

Authors: Lavrushko S.I. , Stepanenko V.I. 
Published: July 2021

Objective — to develop a method of modern molecular genetic diagnosis of microsporia in children based on polymerase chain reaction (PCR), which will allow identification of the pathogen of Microsporum canis at the DNA level.
Materials and methods. The study included 40 patients with microsporia of smooth skin, scalp, scalp and smooth skin. The biological materials for the research were scales from the smooth skin and scalp, hair from the scalp of patients with microsporia. A study of 40 samples of biological material was carried out in patients with microsporia of smooth skin, microsporia of the scalp, microsporia of the scalp and smooth skin. At the first stage, DNA isolation of Microsporum canis was carried out. Then PCR was carried out to increase the copies of the DNA region using specific primers. The final step was typing 40 samples of clinical material of patients.
Results and discussion. PCR diagnostics made it possible to identify the DNA of Microsporum canis in all 40 samples of biological material of patients with microsporia. In our study, we developed a PCR-based method for diagnosing microsporia, which uses a set of two MC primers (regions of the beta tubulin gene of Microsporum canis). For internal control of the course of amplification and the quality of biomaterial sampling, specific primers of APOE (a region of the human apolipoprotein E gene) were also used.
Conclusions. In order to improve the precise specific diagnosis of microsporia in children, a method of modern molecular genetic diagnostics based on polymerase chain reaction (PCR) has been developed, which allows identification of the Microsporum canis pathogen at the DNA level. Analysis of the molecular structure of the genome of Microsporum canis proved that the most objective diagnosis of microorganisms is the PCR method. The developed method of DNA diagnostics based on PCR using specific primers can be included in the algorithm for detecting Microsporum canis in humans.

Published: July 2021

Objective — to conduct an in-depth search of foreign and national literary sources, in particular, reports about the results of randomized controlled clinical trials regarding the use of local combination drugs for the treatment of psoriatic onychodystrophy. The focus is on both short-term and long-term therapeutic effects, as well as minimizing the side effects.
Materials and methods. We conducted the analysis of the world experience of using the local combination drug Onychocid® Emtrix for the treatment of psoriatic onychodystrophy and minimization of side effects by searching for data (2010—2021) in the Cochrane Library controlled tests by keywords: psoriasis, onychodystrophy; in PubMed, High Wire Press, Google Scholar — by terms of the catalog and medical subjects: psoriasis + onychodystrophy + treatment; reports of randomized controlled clinical trials, meta-analyses and literature reviews.
Results and discussion. The modern view on the problem of psoriatic onychodystrophy, methods and approaches to the treatment of this pathology are presented.According to the analysis of the results of foreign and national studies, Onychocid® Emtrix is proved to be clinically efficient and safe as complex treatment for various clinical forms of psoriatic onychodystrophy. It contains a combination of propylene glycol, urea and lactic acid. Active substances, which are part of the drug, are synergists, which provides triple action of ingredients — combining moisturizing and keratolytic effects with antifungal properties. Most patients showed an early (in the 2nd to 4th week of use of the drug) improvement in the appearance of the affected nails. In the future, they observed thinning of nail plates, color restoration, disappearance of excessively keratinized nail tissue, tendency to the restoration of the integrity of nails. The use of this topical medication provided high compliance due to an excellent profile of tolerance and the possibility of application once a day.
Conclusions. It has been proven that the modern medication of local action Onychocid® Emtrix is currently the most optimal treatment for psoriatic onychodystrophy which allows achieving a therapeutic effect both in monotherapy and in the standard complex schemes. Treatment of psoriatic onychodystrophy with Onychocid® Emtrix is more effective in comparison with standard therapy, contributes to a rapid partial or full restoration of the integrity of nail plates. The high effectiveness and safety of Onychocid® Emtrix give reason to recommend it for inclusion in the schemes of complex treatment of patients with psoriatic onychodystophy.

Applicability of the ultra-high radio frequency band (UHF) for hydrometeor detection by phase difference method
Authors: FABO Peter , NEJEDLÍK Pavol , KUBA Michal , ONDERKA Milan , PODHORSKÝ Dušan 
Published: July 2021

Hydrometeors (rain, fog and ice crystals) affect the transmission of electromagnetic signals. Previous research showed that alterations in the signal (amplitude and phase) are affected by the composition of the atmosphere, e.g. the presence of hydrometeors. The majority of hydrometeorological detecting methods are based on the attenuation of electromagnetic signals as they penetrate the atmosphere. Novel methods based on monitoring of parameters of the signal appeared in recent time. This article presents the first results from our investigation of how hydrometeors affect the phase differences in signals transmitted by BTS stations. Cell phone operators transmit electromagnetic signals in the 1 GHz frequency band. This paper describes a novel concept of how phase differences between two signals arriving at two different antennas can be used to detect hydrometeors. Although the described concept is assumed to be independent from the signal strength, the analysed signal must be detectable. The primary advantage of the proposed passive method is that the signal is almost ubiquitous and does not require demodulation. In densely populated areas, the network of BTS stations reaches a spatial density of 1 station per 1 km2 which gives excellent opportunity to use the signal for detection purposes.
Zmiany w koniunkturze gospodarczej Polski w wyniku epidemii COVID-19
Authors: Rokicki Tomasz 
Published: July 2021

Celem głównym pracy było rozpoznanie sytuacji i przedstawienie zmian w koniunkturze gospodarczej Polski w wyniku epidemii COVID-19. Źródła materiałów stanowiła literatura przedmiotu, dane GUS. W pracy wykorzystano metodę porównawczą, posługiwano się wskaźnikami koniunktury, obliczono współczynnik koncentracji Giniego dla liczby zachorowań oraz przedstawiono stopień koncentracji za pomocą krzywej Lorenza. Zastosowano również współczynniki korelacji liniowej Pearsona. Do prezentacji wyników badań wykorzystano metodę opisową, tabelaryczna i graficzną. Stwierdzono pogorszenie się koniunktury gospodarczej we wszystkich sektorach gospodarki, największe w usługach i przemyśle, najmniejsze zaś w budownictwie. Występowały też różnice w działalnościach przypisanych do poszczególnych sektorów. Z reguły większe przedsiębiorstwa mniej odczuwały skutki kryzysu gospodarczego. Skala pogorszenia się koniunktury w 2020 r. była większa niż w latach 2008-2009. W czasie epidemii miały na nią wpływ zakaz administracyjny prowadzenia działalności oraz możliwość wykonywania pracy zdalnej. Te działalności, które były wykonywane zdalnie, zyskiwały lub traciły mniej. W przypadku braku takiej możliwości i zamknięciu zakładu nie było szansy na uzyskiwanie zadawalających przychodów. Większa liczba przypadków zachorowań w danym województwie wiązała się z lepszą koniunkturą i zapotrzebowaniem na usługi przewozowe, dostawy towarów bezpośrednio do domów.

Status quo jest ważnym efektem występującym w procesie podejmowania decyzji. Badacze określają w ten sposób nieświadome podtrzymywanie stanu bieżącego i niechęć do zmian. W niniejszym artykule w wyniku badania założone hipotezy nie zostały całkowicie potwierdzone. Zauważono statystycznie istotną zależność między grupą neutralną a grupą, w której status quo występował przez 3 miesiące, co mogłoby potwierdzić założone hipotezy o uleganiu temu efektowi. Kolejny wynik grup ze status quo – 3 miesiące oraz status quo – 20 lat przeczy wpływowi czasu na podatność na heurystykę. Rezultaty badania mogą wynikać z czynników, które jednocześnie stanowią istotne wskazówki dla badaczy zainteresowanych tą tematyką.
