Language management, discursive power, and English as lingua franca in island countries and territories
Authors: Wang Yangyu , Zhong Shuneng
Published: October 2022

Both geographical factors and colonial histories have contributed to the marginalization of many islands. In the context of globalization, European colonial languages often dominate, and the Standard English ideology has been gradually internalized alongside the spread of English worldwide. Islands face an apparent tension between promoting local languages for the purpose of strengthening social and cultural cohesion and maintaining the favored status of European colonial languages in order to facilitate integration into global markets. Languages are, however, ideologically constructed, and the dominant status of English and other European languages on islands has created a cultural system of ideas, norms, and values originating from the West. This turns islands into norm followers, creating difficulties for the construction of island identities and making it impossible to act from a position of discursive power on the international plane. This paper argues that island governments should carry out language management in such a way as to promote the idea of English as a lingua franca for use in global intercultural communications and thereby enhance the island’s discursive power while strengthening social and cultural cohesion.

Published: October 2022

At the end of December 2019, cases of pneumonia of unknown etiology were registered in China. The cause represented by the novel coronavirus SARS-CoV-2 was established later. The infection has spread rapidly around the world. According to the latest official data, over 531,959,093 cases of the infection and over 6,299,068 confirmed COVID-19-related mortality cases were reported in 215 countries. The study aimed to examine characteristic features of the novel coronavirus pandemic in Russia, Brazil, and India from April 2020 to March 2022. Official statistical data on COVID-19-related morbidity, mortality, and vaccination from the websites of the Russian Federal State Agency for Health and Consumer Rights and Johns Hopkins Institute were collected for every country from April 01, 2020, to March 01, 2022. Out of the three examined countries, the highest incidence and mortality for COVID-19 per one million people were found in Brazil, followed by Russia and India respectively. The level of vaccination was the highest in Brazil (73%). It was followed by India (53%) and Russia (50%). The Delta variant of the virus was first identified in India in October 2020. In June of the next year, it accounted for the majority of COVID-19 cases registered in three countries. The same was true for the Omicron variant. Despite the efforts taken within the last two years to contain COVID-19 (development of vaccines, use of other antiepidemic agents), the coronavirus infection is still of cyclical patterns along with increased morbidity. Based on the obtained data, massive vaccination effectively reduced mortality due to COVID-19 though many new variants occurred.
Biological contamination of water in Russian water bodies and its epidemiological significance
Authors: Evtodienko AM , Zdolnik TD
Published: October 2022

Drinking water, household water, and recreational water can be the vehicle of infections and invasions transmitted by fecal‑oral route. In this paper we studied the impact of the quality of water in water bodies on the incidence of enteric infections and invasions in the population of the Russian Federation based on the State reports “On the State of Sanitary and Epidemiological Well‑Being of the Population of the Russian Federation” issued by the Federal Center of Rospotrebnadzor in 2011–2020. Based on microbiological parameters, the quality of water from the centralized sources of water supply in the Russian Federation corresponds to microbiological parameters of water in waterworks before entering the distributive pipelines (3.5 and 2.9% off‑nominal tests, respectively, Rxy = 0.98). Giardia cysts were found in 0.06% of the assessed water samples collected from the centralized sources of water supply. This parameter correlates with the percentage of off‑nominal microbiological water tests (Rxy = 0.84). The values of biological water contamination tend to decrease. The incidence of acute enteric infections and giardiasis shows a negative trend and correlates with the indicators of biological water contamination obtained for water from the centralized sources of water supply and grade II reservoirs. The findings, that support the literature data on the impact of biological water contamination on the incidence of enteric infections and invasions in the population, highlight the relevance of maintaining the sanitary and hygienic condition, as well as providing thorough sanitary and hygienic control of water bodies.
Estimating harmful effects of mobile electronic gadgets on health of medical students
Authors: Ievleva OV
Published: October 2022

It is difficult to imagine a modern society without electronic gadgets (EG), as they promote rapid acquisition and exchange of data. At the same time, modern technologies do not only ensure information exchange, but also influence different organs and systems of users. As they are more commonly used by students and adolescents, it is important to have a holistic picture of the effect produced by the EG to estimate the harmful effects of various mobile EG. The harmful effects on health of medical students associated with the use of mobile electronic gadgets was assessed. Scientific articles considering the issues of how various environmental factors and harmful effects associated with the excessive use of electronic mobile gadgets influence the health of students were reviewed. The articles published in 2015 to 2021 were searched within ELIBRARY, PUBMED, PSYCINFO and CYBERLENINKA. Thus, taking into account literature data about the health of modern students, their way of life, role and place of electronic gadgets in their lives, and a special importance of forming health-preserving skills exactly among medical students, who are the future doctors, subsequent examination of harmful effects, associated with mobile electronic gadgets used in educational and leisure activity, on students’ health, examining the effect of mobile electronic gadgets on other components of the students’ way of life and development of modern technologies of hygienic education of medical students at Universities still belong to relevant issues. Development of electronic technologies enables acquisition and processing of large amounts of information. However, various factors producing a negative effect on health and a way of life of a human being are poorly understood. In spite of diversified information technologies, it is important to remember about the necessary skills used when the technologies are applied. Thus, health and skills related to a healthy lifestyle belong to an important factor for future medical students.

Up to now, few factors have been identified to predict successful pulmonary vein isolation, none of which with high predictive values. The objective of our study was to compare different predictive factors of atrial fibrillation recurrence after pulmonary vein isolation,including new parameters of the right atrium (area and index volume). We retrospectively analysed data from 66 patients and included echocardiogram parameters performed within 18 months prior to the ablation procedure. We excluded patients with left ventricular dysfunction (defined as a left ventricular ejection fraction < 50%); previous diagnostic of cardiomyopathy; severe valvular heart disease; severe pulmonary hypertension; or those with poor image quality in the echocardiogram. We considered atrial fibrillation recurrence to be the presence of atrial fibrillation of 30 seconds or longer demonstrated by a standard electrocardiogram or in a 24-hour Holter electrocardiogram within a year after the ablation procedure. We found that the right atrium area (odds ratio = 1.52; 95% confidence interval 0.95–2.43, P = 0.08) and a previous pulmonary vein isolation procedure (odds ratio = 0.21; 95% confidence interval 0.04–1.01, P = 0.05) were nearly statistically significant predictors of successful atrial fibrillation ablation at one year. Although our study was limited because of a low number of patients and because it is a retrospective analysis, we found that a higher right atrial area may be related to the late recurrence of atrial fibrillation. This tendency may be useful in predicting patient outcomes.
Major Interleukins: Role in the Pathogenesis of Atrial Fibrillation
Authors: Rafaqat Saira , Rafaqat Sana , Rafaqat Simon
Published: October 2022

Interleukins (IL) are a group of cytokines with complex immunomodulatory functions, whereas atrial fibrillation (AF) is the most common cardiac arrhythmia. This review article highlights the role of major IL in the pathogenesis of AF. IL-1 had elevated levels in permanent and persistent AF patients as compared to paroxysmal AF. A study had shown a straightforward connection between the development of postoperative atrial fibrillation and IL-2 sera levels shortly after cardiopulmonary bypass graft for the first time. IL-4 has been involved in anti-inflammatory response and played no role in the contribution of AF. The elevated level of IL-6 rapidly induces atrial electrical remodeling by downregulating cardiac connexins. This change could be significantly increased the risk of AF and related complications during active inflammatory processes. Moreover, a study has shown higher IL-8 levels in permanent AF patients as compared with paroxysmal AF patients. An association was found between IL-10 gene -592A/C polymorphism and AF in Han Chinese. Recombinant human IL-11 therapy shortened atrial refractoriness and also created favorable conditions for AF by an indirect mechanism involving volume expression, stretching of atrial myocardial tissue and sodium retention. An elevated IL-12 expression was observed in the left atrial tissues of AF patients. IL-17 signaling pathway has played a significant role, and some genes could be used as potential therapeutic targets for AF. An association between the risk of AF with single nucleotide polymorphism of IL-18 and also resulted in the increased left atrial diameter and decreased left ventricular ejection fraction in AF subjects as compared to control. IL-27 genetic variants had increased the occurrence of AF. AF patients had elevated levels of IL-37 that were closely linked with AF subgroups.
STUDI ANALISIS TENTANG MAKNA NIKAH SIRRI DALAM PERSPEKTIF HADIS
Authors: Nurinayah
Published: October 2022

Nikah sirri merupakan term klasik yang menarik perhatian kalangan para pemikir hukum Islam sejak masa klasih hingga modern terkait pengembangan dan perluasan makna yang terjadi di berbagai wilayah dunia yang menggunakan hukum Islam sebagai landasan dalam pembentukan peraturan perundang-undangan khususnya negara Indonesia mengingat motif dari larangan agama untuk melangsungkan perkawinan secara sirri dengan pertimbangan dampak negatif yang ditimbulkan dari perkawinan tersebut. Dengan terjadinya perluasan makna dalam term tersebut melahirkam pemahaman baru dalam hukum perkawinan khususnya dalam bidang administrasi perkawinan. Sebagian ulama berpendapat bahwa nikah sirri adalah nikah yang disembunyikan maka pernikahan haruslah diumumkan. Namun bagi yang berpendapat bahwa nikah sirri adalah tidak sempurnanya saksi, maka haruslah menghadirkan saksi secara sempura baik dua orang laki-laki atau seorang lelaki dan dua orang wanita, dan meskipun tidak disiarkan maka pernikahannya tidaklah dinamakan nikah sirri, serta yang terakhir konsep nikah sirri dalam artian perkawinan yang tidak tercatat pada lembaga pencatatan perkawinan, maka diharuskan untuk mencatatkan perkawinannya.

This study aimed to evaluate K, Ca, Mg, Al concentrations and active acidity (pH-H2O) in different cropping systems for onion. The study was conducted on a Humic Dystrudept in Ituporanga, Santa Catarina state, Brazil, where eight different cropping systems for onion were evaluated, namely: T1: maize-onion succession, T2: common vetch-maize/rye+fodder raddish-onion-maize/rye+fodder raddish-common bean, T3: rye-onion-maize/black oat-maize, T4: onion-velvet bean succession, T5: rye-onion-millet/black oat-onion-millet, T6: rye-onion-velvet bean succession, T7: onion-velvet bean+millet+sunflower succession, from T1 to T7 were conducted under no tillage system (NTS), T8, T8: maize-onion succession, was conducted under conventional tillage system. We used the randomized complete block design, with 5 replications. All the chemical samples were collected and evaluated at the 0-5, 5-10 and 10-20 cm soil layers. We observed that the different cropping systems were similar in terms of Ca, Mg and K concentrations in all the soil layers, significant differences were only found for exchangeable Al concentrations at the 0-5 cm layer. More time is needed to observe better the performance of the treatments since their effect on the soil depends a lot on the time of implantation.

Published: October 2022

Depending on the enrichment levels, enriched uranium can be used for many purposes, such as the fabrication of fresh fuels for power and research reactors. Furthermore, under the 1968 Treaty on the Non-Proliferation (NPT), the states, specifically non-nuclear-weapon states of comprehensive safeguards agreements, should be inspected and verified to prove "peaceful use" commitments. Consequently, verifying the enrichment process and the percentage is considered an essential element for investigation purposes. The primary motivation of this paper is to estimate and validate U3O8 samples enrichment percentage using innovative formula. The enrichment calculations were conducted using certified safeguarded nuclear materials with varying low enriched uranium (LEU) ratios, both experimentally with a HpGe detector and computationally with Python 3.10 code. The results prove precise and acceptable values compared to the certified declared enrichment percentage (from depleted 0.32% - 4.5%) with differences in the range of 1⁓ 3.8%. The new formula used in this work applies to national, regional, and international safeguards inspection targets.

Authors: Saltykov Yuri V. , Kolosova Anna A. , Feodorova Valentina A.
Published: October 2022

Lumpy skin disease (LSD) is an infectious disease mostly of cattle. The typical clinical picture is usually characterized by the appearance of multiple nodules on the skin and internal organs. They can cover the entire body of the animal in the course of severe illness. This disease causes serious economic damage despite the fact that mortality of cattle with LSD is often low. Now LSD is a serious danger for cattle in the Asian part of Russia (part of the territory of the Russian Federation geographically belonging to Asia) and the Southeast Asia. Initially LSD was an endemic disease in many Sub-Saharan African countries, then it spread to Asia and Europe. In order to prevent the spread of the lumpy skin disease virus (LSDV), strict quarantine is introduced, vector control is carried out and various other LSD control measures are implemented. An effective vaccination campaign is required to significantly reduce the morbidity. However, the risk of spreading this transboundary disease to neighboring LSDV virus-free countries and regions of Asia, remains high enough. This article contains a summary of the available information about the spread of LSD in Asian part of Eurasia for the period of 1984 - February 2022. We are also discussing the latest available findings on the epidemiology of LSD and the methods currently used for the prevention and control of the LSDV.

The aim of this retrospective study was to evaluate the clinical and radiographic outcomes of 21 cats that underwent coxofemoral toggle stabilization using the Mini TightRope® Fixation System (mTR®). Data were compiled from client-owned cats with traumatic hip luxation. Each cat underwent the same protocol including orthopedic assessment, preoperative radiographic evaluation, surgical procedure, postoperative management and clinical re-examination at 14 days, 8 weeks and 12 months following surgery. Age, body weight, implants and osteoarthritis progression were recorded. A lameness score 0-4 was assigned to each cat. Pain upon hip extension was not quantified but as pain reaction or no pain reaction. Major complications and osteoarthritic (OA) changes were recorded. Osteoarthritic changes were classified on a 0-4 scale. Twenty-one cats were included in the study. Coxofemoral luxations were stabilized using a mTR®. At 8 weeks, weight bearing was considered normal (grade 0) in all cats and no pain reaction was elicited during hip extension. One year after surgery, orthopedic examination was within the normal limits and according to the owners, all animals exhibited a normal physical activity. No complications were recorded. Evidence of slight OA changes were observed in 5 out of 21 cats. The final outcome was considered excellent in 16/21 patients and good in 5/21 cats. The application of the mTR® system can be considered a suitable surgical treatment in cats affected by traumatic hip luxation.

Progressive tissue injury in canine leishmaniosis (CL) is related to the deposition of immune complexes, which induces vasculitis and leads to endothelial dysfunction. Homocysteine (Hcy) increase may worsen endothelial dysfunction, but data concerning its concentration in different CL stages and links to the acute phase response and oxidative stress are missing. We compared Hcy levels between dogs with mild (N=24) and moderate CL without treatment (N=17) and treated with anti-Leishmania drugs and vitamin B supplements (N=9). Dogs with moderate CL, regardless of therapy administration, had more distinct clinical signs, lower erythron values, and a higher level of acute-phase proteins (APPs), IgG against Leishmania spp., urea and creatinine, than dogs with mild CL. Hcy values did not differ between stages, but treated dogs had the lowest levels of Hcy. An inverse relationship existed between Hcy and the CL stage, therapy, levels of IgG, and clinical pathology data. The only positive relationship existed between Hcy and the erythron state. The disease stage and therapeutic intervention were not related to the oxidative stress level, except in the case of paraoxonase-1/Hcy ratio, indicating favorable conditions for antioxidative defense in treated dogs. In conclusion, changes in Hcy levels indicated its possible involvement with endothelial dysfunction and inverse relationship to tissue injury evaluated by APPs. Finally, Hcy might be an early marker of favorable conditions for endothelium recovery in CL.

Published: October 2022

Foot and mouth disease (FMD) is one of the most contagious diseases of livestock with a significant economic impact affecting most countries in the world over the years. In Turkey, FMD is endemic, but there have not been national studies conducted to analyze spatiotemporal pattern of FMD yet. This study was carried out to identify the spatial and temporal distribution of FMD outbreaks in Turkey from January 2010 to December 2019, to guide the eradication following development of control programs against the disease. Thematic maps were produced to determine FMD sensitive regions and Box-Jenkins time series approach was used to analyze the temporal pattern of FMD. Between these dates, 6698 outbreaks and 246341 cases were reported in Turkey, FMD was recorded multiple times in 96.3% of the provinces (n = 78), and the average incidence of FMD outbreaks at the provincial level was calculated as 8.27/province year. As result of the spatial pattern of FMD, East and Central Anatolia were determined as the regions where the disease was observed intensely. The time series plot of the data showed a general not very regular trend although there was a downward trend with irregular variations. Although, there was no seasonal effect detected by the decomposition of time series, seasonal peaks in the outbreaks were observed, in the spring (n = 2087, 31.16%). In conclusion, the evaluation of spatial and temporal pattern based on FMD outbreaks that are common in Turkey will contribute to eradication of the disease.

Published: October 2022

Winter is the season that poses the greatest challenges for honey bee colonies. Therefore, the main approach in beekeeping practice is aimed mainly at providing sufficient quality food supplies for bee colonies in early autumn. We conducted the present study to test the influence of the natural plant extract IMМUNOSTART HERB on population strength, stored pollen area, capped worker brood area, and honey yield. The experimental groups were supplied with IMМUNOSTART HERB 4 times at 7-day intervals, whereas sugar syrup was given to the control groups. The obtained results showed that the applied supplemental diet affected all investigated biological parameters, with the most noticeable effect after the second application. In all measurements, the honey bee colony parameters in the treated groups showed higher values in comparison to the control groups. These results highlight the potential of herbal supplements to effectively improve bee colonies’ development during the period of scarce bee forage, as well as to provide suitable conditions for successful overwintering.
Optimization of a Two-Step Centrifugation Protocol for Bovine Platelet-Rich Plasma
Authors: Kim Mu-Young , Han Hyun-Jung
Published: October 2022

Platelet-rich plasma ( PRP), an autologous platelet concentrated in plasma, is a source of diverse growth factors and is extensively utilized to promote tissue healing. Most of the clinical and laboratory investigations in veterinary medicine have focused on horses and dogs. Consequently, the types and detailed conditions of the PRP preparation method are based on those species. However, in bovine medicine, only a few studies have investigated the species-specific characteristics of bovine platelets. The aim of this study was to optimize the conditions of a two-step centrifugation method for bovine PRP. Whole blood samples were obtained from eight healthy lactating Holstein-Friesian cows. Eight running conditions for the first and second centrifugations each were evaluated based on the platelet recovery rate, the concentration of growth factors, and the adenosine diphosphate (ADP)-induced aggregation response, which reflects the premature platelet activation caused by the centrifugation process. The results of this study showed that for the first and second centrifugations, 900×g for 10 minutes and 1250×g for 15 minutes, respectively, were the most suitable conditions for the platelet recovery rate, and the concentration of growth factors was highest under these conditions without significant activation of premature platelet aggregation. Thus, we established an optimal two-step centrifugation protocol for bovine PRP that should provide a better understanding of bovine platelets.

Authors: Baek Su-Min , Lee Seoung-Woo , Park Jin-Kyu
Published: October 2022

Mammary gland tumor is rare and only a few cases have been reported in wild animals. Moreover, most etiologies of the known cases in veterinary medicine are related to age, diet, obesity, and excessive sex hormones in domestic animals while few etiologies are reported in wild animals. An unknown-aged female wild boar was presented to the Department of Veterinary Pathology, Kyungpook National University with a well-demarcated, and firm-to-elastic mammary gland mass. The cut-surface of the mass was pink-reddish, and homogeneous. Microscopically, the mass was mainly composed of well-differentiated neoplastic glandular epithelial cells characterized by a single-layer, columnar to cuboidal shapes, and small and central nuclei and nucleoli. Any evidence of invasiveness or metastases of the neoplastic cells were not observed. Interestingly, infiltration of chronic inflammatory cells such as plasma cells and macrophages was observed along with a large quantity of gram-negative and positive bacterial colonies in the mammary glands. Moreover, accompanied fibrosis of stroma was observed, as well. Based on the gross and microscopic findings, the present case was diagnosed as mammary simple adenoma caused by chronic mastitis progressing to fibrotic condition.

Chronic renal failure is one of the leading causes of death in African lions, cheetahs, and tigers. Conventional methods to measure renal dysfunction include measuring serum creatinine and blood urea nitrogen (BUN). Symmetric dimethylarginine (SDMA) measurement is a reliable predictor of renal dysfunction in the domestic cat because SDMA serum levels increase early when the kidneys are damaged. Serum SDMA levels were assessed and correlated with creatinine as well as BUN from healthy captive Bengal tigers and lions at the Everland Zoo in Korea. Serum SDMA concentrations were increasingly associated with increased age in lions. However, SDMA concentrations were higher in some young Bengal tigers than in older ones, which may allow for earlier renal dysfunction detection in these young cats than would be BUN and creatinine alone. In Bengal tigers, the correlation between the SDMA and BUN was slightly higher than that between SDMA and creatinine. In lions, SDMA correlated better with creatinine than with BUN concentration. These results show that serum SDMA concentration can be used as a biomarker for age-associated renal dysfunction. SDMA measurement may be an essential preventive management method in zoos.

Random Fourier features represent one of the most influential and wide-spread techniques in machine learning to scale up kernel algorithms. As the methods based on random Fourier approximation of the kernel function can overcome the shortcomings of machine learning methods that require a large number of labeled sample, it is effective to be applied to the practical areas where samples are difficult to obtain. Network traffic forwarding policy making is one such practical application, and it is widely concerned in the programmable networks. With the advantages of kernel techniques and random Fourier features, this paper proposes an application of network traffic forwarding policy making method based on random Fourier approximation of kernel function in programmable networks to realize traffic forwarding policy making to improve the security of networks. The core of the method is to map traffic forwarding features to Hilbert high-dimensional space through random Fourier transform, and then uses the principle of maximum interval to detect adversarial samples. Compared with the traditional kernel function method, it improves the algorithm efficiency from square efficiency to linear efficiency. The AUC on the data set from real-world network reached 0.9984, showing that the method proposed can realize traffic forwarding policy making effectively to improve the security of programmable networks.

Published: October 2022

With the development of the times and the progress of science and technology, the financial market is constantly reformed and China’s financial industry is gradually modernized. However, China’s economy has been in the stage of rough growth for a long time, which has led to low efficiency in the allocation of financial resources and unreasonable use of funds, and this has seriously restricted the whole social production activities and the stability and sustainable and healthy development of the national economy, so the prevention and control of financial risks is particularly important.Therefore, how to identify and measure the risks in China’s financial industry and manage and invest them in a reasonable way is a very serious issue facing China’s financial institutions today. On the other hand, due to the continuous development and innovation of the financial market, China’s financial industry has been gradually reformed. However, due to the imperfection of China’s economic system and related laws and regulations, some non-performing assets and irregularities in the operation of domestic financial institutions have emerged, and instability in the financial market has also emerged. These phenomena make China’s financial industry face huge financial risks in the process of development.
