Published: May 2022

The thermal decomposition of Zr(acac)4 is studied in a SiC-microreactor on the micro-second time scale. By utilizing synchrotron radiation and photoelectron photoion coincidence spectroscopy, six important zirconium intermediates, as for instance Zr(C5H7O2)2(C5H6O2), and Zr(C5H6O2)2, are identified in the gas phase for the first time. The adiabatic ionization thresholds of intermediately formed zirconium species are estimated and the main products of their thermal decomposition, acetylacetone, acetylallene and acetone are characterized unambiguously and isomer-selectively. Based on all detected intermediates, we deduce the predominant pyrolysis pathways of the precursor in the temperature range from 400 to 900 K. Our findings are complemented by numerical simulations of the flow field in the microreactor, which show that the choice of dilution gas significantly influences the temperature profile and residence times in the microreactor, such that helium provides a more uniform flow field than argon and should preferentially be used.

Graphical abstract

Using a soft ionization method coupled to velocity map imaging (VMI), leads to valuable insights in the thermal decomposition of Zr(C5H7O2)4, used in the synthesis of functional nanomaterials and ceramic coatings. Thanks to the use of a microreactor, important gas

Introduction: The Anthropocene is used to describe the most recent period where major disruptions in Earth’s system processes have resulted from humanity’s increasing ecological footprint. Climate change affects the social and environmental determinants of good health, such as clean air, stable ecosystems, safe drinking water, and sufficient and safe food, and they seem to be closely related to air pollution.
Objectives: This article aims to review the evidence of how extreme weather events and indoor and outdoor pollution are associated with insufficient lung growth in early life, changes in lung function, and the increase in respiratory infections, favoring the development of allergic respiratory diseases.
Material and Methods: Non-systematic review of English, Spanish, and Portuguese articles published in the last ten years in databases such as PubMed, EMBASE, and SciELO. The terms used were air pollution OR climate changes OR smoke, AND health OR allergic disease.
Results: Climate change and air pollution are the leading contributors to health emergencies around the world. On a global scale, those most at risk of adverse health effects associated with climate change include children, the elderly, and other vulnerable groups. Climate change and air pollution have adverse impacts on respiratory allergies, and the mechanisms are complex and interactive.

Methodology. The use of methods of analytical classification and systematization of existing monitoring methods in the field of practical research and obtained field results.
Findings. Power transformers remain the heart of the power grid and Smart Grid network of any level of the hierarchy of structure and architecture. As a rule, the transformer as an estimated element of the network is put into operation once and kept in working loads, alternating monitoring and scheduled restoration work, until the complete loss of working condition required for the operation requirements. Therefore, most transformers are in operation over the regulated period of more than 20 years.Carrying out the need for flexible analytical assessment and classification of existing methods of monitoring the power transformer, systematization of known information for a wider range of specialists in the energy sector.
Originality. It is established that due to the complexity of modern monitoring methods the time required for their selection and use in accordance with the structure of the transformer decreases with increasing systematization and classification of the relevant methodological material. The presented systematization reduces the cost of time and material resources when choosing the necessary method of the power transformer monitoring.
Practical value. Systematic classification of available monitoring methods in the appropriate relation to the families of methods and zones of monitoring mounting to search for a signal of transformer failures.

Epigenetic change refers to a phenotypic alteration

without permanent genotypic change, which occurs

through chromatin modification, DNA methylation,

histone modification, chromatin-regulating proteins

and non-coding RNAs. Post-transcriptional m6A

RNA methylation is also a newly described epigenetic

mechanism and believed to be a new diagnostic

biomarker and potential therapeutic target. It is a well-

known fact that epigenetic changes play a significant

role in the development and progression of several

nonneoplastic and neoplastic diseases. Therefore,

epigenetic changes are of value in diagnostic

and prognostic terms. On the other hand, with the

development of personalized medicine and targeted

treatment approaches, treatment strategies targeting

the epigenetic changes are becoming a promising

area for many diseases. The aim of this review is

to provide information about the mechanisms of

epigenetic changes and their role in the development

of neoplastic and nonneoplastic diseases, which may

be helpful for the clinicians and laboratory medicine

experts for further researchs.
Method of heat and mass transfer calculation of cooling technical water process at CHP plant when cooling pond with spray devices is operated

Published: May 2022

The generation of electrical energy at thermal and nuclear power plants is associated with outward heat transmission of large amount. Cooling devices (cooling towers, spray pools, reservoirs) are used for its utilization. The increase of the efficiency of the cooling capacity of this equipment in the circulating water supply system of the CHP plant is occurred due to a decrease of temperatures that meet the optimal technical and economic performance of the facility. The studies of I.I. Makarova, V.A. Gladkova, B.S. Farfarovsky, Z.K. Maimekova, S.A. Suprun are devoted to these issues. The aim of the study is to develop a methodology to calculate the process of cooling technical water to create an operating temperature mode of the equipment during condensation of the waste heat of steam turbines and to minimize the amount of additional water from the Tom River in the warm season. To evaluate the operation of spray devices the authors have used experimental data obtained during the survey of the cooling pond of the West Siberian CHP plant in Novokuznetsk city and methods of physical modeling of heat and mass transfer. To increase the efficiency of technical water cooling at the CHP plant, it is proposed to install spray devices in addition to the existing cooling pond. A method has been developed to calculate the process of water cooling in spray devices during collaboration with a cooling pond. The method is based on the calculation of the optimal water temperature at the intake point in accordance with the operating parameters of turbine generator condensers. The method differs from the existing ones as it considers the influence of heat transfer and mass transfer phenomena in the boundary layer near the surface of dispersed drops water. The experimental and calculated results confirm that the use of spray devices in the cooling pond reduces the amount of additional water taken from the Tom River compared to its limit flow by almost 10 times at the established temperature difference during the condensation of exhaust steam in the summer period of the year. The method to calculate the cooling of technical water in a cooling pond with spray devices is recommended for implementation at the West Siberian CHP plant in Novokuznetsk city.
All-Ukrainian Union of Farmers-Owners (Peasants) and the Ukrainian People’s Party: Little-Known Pages in the History of Party Building during the Ukrainian Revolution of 1917–1921
Authors: Liubovets Olena
Published: May 2022

The Ukrainian revolution of 1917–1921 was a period when for the first time were formed the real conditions for the multiparty system in Ukraine, during which a virtually full party spectrum was formed – from left to right. The political alternatives generated by the revolution were the cause of a constant inter-party and intra-party struggle to develop a model of national building in Ukraine and to determine the main directions of government socio-economic policy. The result was party splits. The article analyzes the reasons for the split of the All-Ukrainian Union of Landowners and the creation of the All-Ukrainian Union of Farmers-Owners (Peasants) on its basis. The leaders of the newly formed Union advocated the creation of an independent parliamentary-type Ukraine led by the hetman, and considered the wealthy peasantry to be their social support. The anti-Hetman uprising hindered the development of the Union’s activities. During the time of the Directory of UNR, the Union could not become a full-fledged party. In May 1919, the Union was transformed into the Ukrainian People’s Part, which exists a little over a year, but also failed to become an influential political party. It was small and little known to the public. In the political spectrum of the UNR, the party held a centrist position, but the ruling socialist parties considered it as «right».
Characterization of Diaporthe ampelina isolates and their Sensitivity to Hot-Water Treatments and Fungicides in in vitro
Authors: AKGÜL Davut Soner , AWAN Qamar Nawaz
Published: May 2022

Diaporthe ampelina (=Phomopsis viticola) is one of the most important pathogens causing both cane/leaf spot and wood canker diseases in grape growing countries in the world. In this research, morphological, molecular and pathogenic characterization of 23 D. ampelina isolates were studied and their sensitivity was tested against hot-water treatments and some of the fungicides used in vineyards. Morphologically, the isolates were grouped according to “W type” and “G type” colony appearance and microscopic features. In molecular characterization, beta-tubulin, calmodulin and translation elongation factor (tef1-α) gene regions were amplified with PCR. The nucleotide sequences were analyzed using NCBI-BLAST search and recorded in GenBank, through which species identity was also confirmed. Mycelial viability was tested against hot-water treatments (46 – 50°C for 30 and 45 min) in centrifuge tubes and thermal inactivation point was determined. It was also tested against some of the fungicides (azoxystrobin, boscalid, cyprodinil, tebuconazole, azoxystrobin + cyproconazole + tebuconazole, cyprodinil + fludioxonil, azoxystrobin + tebuconazole and fludioxonil) in vitro and EC50 values were calculated. The morphological and molecular study results showed that all the isolates were D. ampelina and they were pathogenic on wood tissues of vines. Thermal inactivation of “W type” isolates was ensured at 48°C-30 min hot-water treatments. Although this treatment also reduced colony growth of “G type” isolates, it did not inhibit it completely and 48°C-45 min treatment was needed to reach full eradication. Considering fungicide sensitivity, fludioxonil or tebuconazole containing fungicides were the most effective in suppressing the mycelial growth of the fungus. However, azoxystrobin, boscalid, cyprodinil could not perform a strong inhibition when compared to fludioxonil and tebuconazole.

Bu çalışmada, yerel bir diatom toprağı olan BGN-1'in, ergin Alman hamamböceklerine (Blatella gemanica (L.)) karşı beton, seramik ve parke yüzeyler üzerindeki ölümcül etkileri araştırılmıştır. Bu üç farklı yüzey üzerinde, B. germanica erginlerii 6 gün boyunca 2.5, 5, 10 ve 20 g/m2 dozlarda BGN-1 kodlu diatom toprağına maruz bırakıldı. Tüm yüzey uygulamalarında BGN-1 diatom toprağı maruz kalma süresi ve diatom dozlarının, B. germanica erginlerinin ölüm oranlarında önemli etkiye neden olduğu görülmüştür. BGN-1 diatom toprağı 2.5 g/m2 dozunda tüm uygulama yüzeylerinde en düşük böcek ölüm etkisine sahip olduğu görülmüştür. 2.5 g/m2 BGN-1 dozu beton yüzeyde 6 gün sonra % 100 B. germanica ergin ölümüne neden olurken ve seramik ve parke yüzeyde dördüncü günün sonunda % 100 ölüme neden olmuştur. Diğer yandan, 5 ve 10 g/m2 BGN-1 dozları ikinci günün sonunda tüm yüzeylerde % 100 B. germanica ölümüne neden olurken, en yüksek 20 g/m2 BGN-1 dozu uygulanan tüm yüzeylerde ilk gün sonunda%100 B. germanica ölümüne neden olmuştur. Genel olarak, BGN-1 diatom toprağının B. germanica erginlerine karşı ölüm aktivitesinin her üç yüzeyde de benzer olduğu tespit edilmiştir. Bu çalışmanın sonunda, BGN-1 kodlu Türk diatom toprağının, medikal bir zararlı olan B. germanica ile mücadelede iyi bir alternatif olabileceği ortaya çıkmıştır.

El área de matemáticas se apoya en recursos visuales como gráficas, operaciones y procesos algorítmicos en el tablero, lo cual representa una dificultad para los estudiantes con discapacidad visual y genera exclusión en las aulas. Por esto, el presente estudio de caso tiene como objetivo identificar los factores socioculturales que inciden en la resolución de problemas matemáticos, a través de una metodología de enfoque etnográfico. Así, se plantea que los docentes deben generar un ambiente de participación e incorporar un modelo de educación diferencial en las aulas con el fin de eliminar factores socioculturales como la discriminación, exclusión y subestimación, que inciden en los procesos de resolución de problemas por parte de los estudiantes con discapacidad visual.
The Study of Sensitivity to Proteolysis of Full-length and Truncated Forms of Recombinant Human Renalase Expressed in the Prokaryotic System
Authors: Fedchenko V.I. , Kaloshin A.A. , Kaloshina S.A. , Kopylov A.T. , Medvedev A.E.
Published: May 2022

Renalase (RNLS) is a flavoprotein; its N-terminal peptide (amino acid residues 1-17) performs various important functions. Inside cells, it is involved in the Rossmann fold formation (residues 2-35), which is necessary for the binding of the FAD cofactor and the manifestation of the enzymatic activity of RNLS as a FAD-dependent oxidoreductase (EC 1.6.3.5). When RNLS is secreted into the extracellular space, this peptide is cleaved off, and the resulting truncated extracellular RNLS can no longer bind FAD and, therefore, numerous effects described in the literature are carried out by non-catalytic mechanisms. In this work, we have investigated the sensitivity to trypsinolysis of two recombinant forms of human RNLS expressed in prokaryotic cells: (a) full-length RNLS containing the FAD cofactor; (b) a truncated RNLS lacking the 1-17 N-terminal peptide (truncatedRNLS, tRNLS) unable to bind the FAD cofactor. Trypsin (1 unit/20 μL of medium) effectively cleaved both forms of renalase (RNLS and tRNLS). When exposed to a lower concentration of trypsin (0.1 U/20 μL of medium), full length RNLS was more trypsin resistant than tRNLS. We suggest that the different sensitivity of RNLS and tRNLS is apparently determined by the presence of the FAD cofactor in the full-length recombinant protein, which contributes to the formation of a spatial structure that is more resistant to the action of certain proteases.
Precarización laboral, desigualdad y nuevas tecnologías
Authors: Vergès Claude
Published: May 2022

Propósito/Contexto. En este artículo se analiza el impacto de la inteligencia artificial para resolver las desigualdades existentes en América Latina.

Metodología/Enfoque. Se revisaron las estadísticas laborales y educativas oficiales de las Naciones Unidas y las aplicaciones de la inteligencia artificial en América Latina y El Caribe, y se analizaron desde la bioética y los derechos humanos.

Resultados/Hallazgos. La precariedad del empleo y el pobre acceso a la educación son permanentes en todos los informes. En este contexto, el reemplazo de las actividades por la inteligencia artificial presenta un riesgo alto a mediano para el empleo en el sector privado.

Discusión/Conclusiones/Contribuciones. El discurso predominante glorifica los beneficios de la tecnología, sin tomar en cuenta las desigualdades existentes. Sin embargo, este instrumento de transformación productiva debe ser evaluado analizando las relaciones de poder y su impacto social. La educación es una respuesta insuficiente mientras no se integra a las prioridades nacionales de desarrollo humano. La implementación de las diferentes formas de tecnología digital debe ofrecer alternativas reales de empleo pleno y seguro, cumpliendo con los artículos 14 y 16 de la Declaración Universal sobre Bioética y Derechos Humanos de 2005.

Published: May 2022

The CRISPR/Cas9 system is a gene editing method capable of accurately locating and altering a specific sequence of a genome. Currently, this technique stands out as a promising biotechnological tool for the improvement of different crops, overcoming the limitations of conventional breeding methods and accelerating the development of plants’ agronomic characteristics. The basic principle of genome editing via CRISPR is to cause a double-stranded DNA break at a predetermined location by a sgRNA (single guide RNA) and through internal repair mechanisms cause mutations and, consequently, genetic variability. In prokaryotic organisms, it is an immune system that naturally protects against viral infection and has been modified to create different applications in higher organisms in the field of medicine and agriculture. In agriculture, it has been used in a large number of mono and dicotyledonous plants, including those of great commercial value such as soybean, cotton and maize. In maize, this technique has been used as a biotechnological tool for increasing production, quality, nutritional value, tolerance to biotic and abiotic stresses. CRISPR-Cas9 technology has enormous potential to contribute to increased food production with great benefit to the environment. This review explores the bases for the use of CRISPR/Cas9 technology to generate genetic variability and its use in the development of maize cultivars with better agronomic characteristics.

Covid-19 and Urban Migrants in the Horn of Africa: Lived Citizenship and Everyday Humanitarianism
Authors: R. Müller Tanja
Published: May 2022

This article focuses on the everyday humanitarianism of migrant communities in three cities in the Horn of Africa: Nairobi, Addis Ababa, and Khartoum. It is framed around the concept of lived citizenship, defined as a means to secure wellbeing through everyday acts and practices. Based on an analysis of comparative interview data among Eritrean and Ethiopian migrant communities in each city, the article argues that the Covid-19 pandemic has impacted lived citizenship practices to different degrees, linked to previous forms of precarity, and the means and networks of coping with those. Disruptions of transnational support networks resulted in a turn towards local networks and everyday practices of solidarity. These forms of everyday humanitarianism range from spontaneous to more organised forms, united by a perceived lack of involvement by international humanitarian actors and the local state. The article raises important questions in relation to transnational humanitarian action in a global crisis.

The Dilemma of Climate-Resilient Agricultural Commercialisation in Tanzania and Zimbabwe
Authors: Newsham Andrew , Naess Lars Otto , Mutabazi Khamaldin , Shonhe Toendepi , Boniface Gideon , Bvute Tsitsidzashe
Published: May 2022

The implications of climate change for agricultural commercialisation – and the implications of agricultural commercialisation for climate change – are profound. On the one hand, agricultural production is, by nature, highly sensitive to climate change and variability. On the other, commercial agricultural production for international food markets is one of the lead sectors for generating greenhouse gas emissions that are driving anthropogenic climate change. This presents the following conundrum: the burden of the changing climate falls most heavily on smallholder farmers in countries across sub-Saharan Africa, where agricultural commercialisation is seen as an important route out of poverty. What, then, are the prospects for climate-resilient, commercially-viable smallholder agriculture in sub-Saharan African countries which are facing this dilemma? We have explored this question through APRA research produced in Singida, Tanzania, and Mazowe, Zimbabwe.
PEMBENTUKAN HOLDING ULTRA MIKRO SEBAGAI TINDAKAN PRIVATISASI BUMN [ESTABLISHMENT OF ULTRA MICRO HOLDING AS PRIVATIZATION]
Authors: Untsa Qaida Dlarieba
Published: May 2022

PP No. 73 of 2021 is the basis for the establishment of the Ultra Micro holding. The topic of this article’s discussion is if the establishment of the Ultra Micro holding can be qualified as privatization and what are the legal consequences of the establishment of the Ultra Micro holding. Based on the provisions of PP No. 73 In 2021, the formation of the Ultra Micro holding is not merely a corporate action carried out by BRI, but is carried out by BRI as a result of PP No. 73 of 2021. The addition of shares in BRI originating from Pegadaian and PNM shares will result in an increase in the proportion of Government-owned shares in BRI, so to maintain the proportion of share ownership owned by the government and other shareholders in BRI, BRI will increase its capital with pre-emptive rights (rights issues). The rights issue has an effect on increasing the ownership of shares circulating in the community, so it can be classified as an act of privatization. The establishment of an Ultra Micro holding can legally result in changes in the Government's control of Pegadaian and PNM, categorized as a takeover transaction (acquisition) so that there is still an obligation to notify KPPU.

BAHASA INDONESIA ABSTRACT

PP No. 73 Tahun 2021 merupakan dasar dilakukannya pembentukan holding Ultra Mikro. Permasalahan yang menjadi pokok bahasan artikel ini adalah apakah pembentukan Holding Ultra Mikro dapat dikualifikasikan sebagai Privatisasi BUMN dan bagaimana implikasi hukum atas pembentukan holding Ultra Mikro. Berdasarkan ketentuan PP No. 73 Tahun 2021, pembentukan holding Ultra Mikro bukanlah semata-mata aksi korporasi yang dilakukan oleh BRI, melainkan dilakukan oleh BRI sebagai akibat adanya PP No. 73 Tahun 2021. Penambahan saham pada BRI yang berasal dari saham Pegadaian dan PNM akan mengakibatkan proporsi kepemilikan saham milik Pemerintah pada BRI meningkat, sehingga untuk tetap mempertahankan proporsi kepemilikan saham milik pemerintah dan pemegang saham lainnya pada BRI, BRI melakukan penambahan modal dengan HMETD (right issue). Right issue tersebut berpengaruh terhadap penambahan kepemilikan saham yang beredar di masyarakat, sehingga dapat digolongkan sebagai tindakan privatisasi. Pembentukan holding Ultra Mikro secara hukum dapat berakibat terhadap perubahan pengendalian Pemerintah pada Pegadaian dan PNM, dan dapat dikategorikan sebagai transaksi pengambilalihan (akuisisi) sehingga tetap terdapat kewajiban notifikasi kepada KPPU.

Autorka polemizuje w artykule z poglądem sądów administracyjnych zakładającym, że art. 181 ustawy Ordynacja podatkowa nie przyjmuje zasady bezpośredniości postępowania dowodowego oraz że nie istnieje prawny nakaz, aby w postępowaniu podatkowym toczącym się równolegle do niezakończonego  postępowania karnego albo karnego skarbowego konieczne było powtórzenie przesłuchania świadka, który zeznawał w ramach tych postępowań, albo powtórzenie przesłuchania oskarżonego, który w ich toku składał wyjaśnienia. Autorka stoi na stanowisku, że art. 181 ustawy Ordynacja podatkowa wyraźnie przewiduje powinność bezpośredniego utrwalania tych dowodów na etapie postępowania podatkowego. W artykule wskazano, że nieuzasadnione zaniechanie tej czynności arbitralną decyzją organu podatkowego godzi w prawo strony do rzetelnego procesu podatkowego, a decyzja oparta na takich dowodach zostaje wydana z naruszeniem prawa i powinna zostać wyeliminowana z obrotu prawnego w ramach jej sądowoadministracyjnej kontroli.

Aby można było scharakteryzować bardzo konkretne i efektywne grupy docelowe, potrzebne jest jednak wykorzystywanie dużych ilości danych online. System informatyczny przetwarza dane dotyczące zachowań użytkowników w sieci — identyfikuje cechy osobowościowe, behawioralne, społeczne i demograficzne. Takie dane pozwalają wyjątkowo dokładnie scharakteryzować odbiorcę w celu precyzyjnego zastosowania tych informacji w komunikacji.

Od pierwszych lat tego tysiąclecia technologia ta jest dość mocno implementowana do polityki. Pozwala to sztabom wyborczym na lepsze opracowanie strategii komunikacji z wyborcami w trakcie wyborów na dany urząd. Polityka cały czas się rozwija, a wybory na poszczególne urzędy są prowadzone w coraz to nowszy sposób. Powstaje tu pytanie, dlaczego to akurat mikrotargeting mierzy się z dużą niechęcią ze strony zwykłych obywateli? Okazuje się tymczasem, że nie ma on zastosowania tylko w polityce. Zidentyfikowano, że może być stosowany też w innych branżach, lecz dlaczego w tym kontekście się o nim nie mówi? Celem niniejszego artykułu jest identyfikacja mikrotargetingu jako formy komunikacji marketingowej oraz pokazanie możliwości zastosowania go w innych branżach. W pracy zastosowano przegląd literatury oraz wykonano badania wtórne na podstawie dostępnych raportów międzynarodowych.

BACKGROUND: To mitigate the COVID-19 pandemic, social isolation was needed. Since individuals with Parkinson’s disease (PD) have a high risk if catching the COVID-19, and physical exercise is one of the most effective treatments for this disease. In this scenario home-based exercise is a great solution to minimize losses by inactivity.
AIM: To report the process of development of a remote physical exercise program based on a face-to-face physical exercise program.
METHOD: We transform a one-hour-session-twice-a-week face-to-face program to a remote format keeping the objectives and structure. The sessions of the face-to-face program were structured by: warm-up, balance, aerobic capacity, resistance training, transference, and cool down.
RESULTS: An asynchronous remote program was chosen to ensure that the participants would be able to perform the physical exercises with a caregiver or family member at home as safely as possible. The sessions were delivered by a single video with all 5 parts with prescriptions (time, sets, and repetitions), instructions about safety, and alternatives exercises. We create two questionnaires to investigate attendance, barriers, safety, and overall experience.
CONCLUSION: This paper purposed an asynchronous program with a single video per session to initiate the remote program for individuals with PD, who already carried out a face-to-face program of physical exercise.

Authors: De Jesus Kelly , Cardoso Larissa M. , De Jesus Karla
Published: May 2022

BACKGROUND: It has been increasingly necessary to assess and monitor the physiological and biomechanics variables of para swimmers to enlarge the current knowledge on how different impairments limit swimming performance and explain each competition class variability in metabolic and technical terms.
AIM: To characterize the front crawl metabolic, kinematic, and coordination behaviors of a trained para swimmer subjected to an incremental protocol.
METHOD: A 44-year-old male, with moderate right side hemiparesis of the body, performed a 200-m front crawl at 5 incrementally paces until exhaustion (0.05 m/s increases and 30-s intervals), with images from two cycles at each step recorded by two video cameras (one surface and one underwater). Kinematic and coordinative variables were collected. Lactate concentrations, heart rate, and blood pressure were also measured.
RESULTS: The para swimmer achieved the anaerobic threshold at  the fourth 200-m step, followed by an increase in heart rate and blood pressure. Speed and stroke frequency were higher and stroke length was lower along the 200-m steps. In contrast, a slight increase in stroke index and stability in intracyclic velocity variations occurred across intensity increments, and index of interlimb coordination was maintained as a superposition mode.
CONCLUSION: The findings suggest that the swimming intensity seems to influence the para swimmer metabolic, kinematic, and coordinative behavior, with sharper alterations after the point when AnT is achieved. In addition to having practical interest for adapted swimming, coaches should emphazise the physiological and biomechanical evaluation on training monitoring to better prescribe and improve the adapted swimming performance.

Authors: Zakirova A. N. , Zakirova N. E.
Published: May 2022

This review presents the results of previously performed epidemiological, experimental and clinical studies indicating the use of ω-3 PUFA (polyunsaturated fatty acids) contributes to reduce the risk of developing cardiovascular diseases. Experimental studies have shown ω-3 PUFA are exhibiting antiarrhythmic effects, improving endothelial function, showing an anti- inflammatory effect, affecting the rheological properties of blood, reducing triglyceride concentrations, and increasing the stability of atheromatous plaque. Wide-scale clinical trials have established high efficacy of ω-3 PUFA in primary and secondary prevention of coronary heart disease. It is found to reduce the risk of ventricular arrhythmias and sudden cardiac death. Also, reduces overall mortality and hospitalization rates due to cardiovascular causes in patients with chronic heart failure. Clinical efficacy among cardiovascular diseases of the prescription drugs ω-3 PUFA standardized by qualitative and quantitative compositions to be studied further in a comparison to the other medications with similar make-up.

Aim. The aim of the research was to study the dynamics of distant cases of the disease that underwent AMI in 2005-2007 (LIS registry) and in 2014 and 2018 (LIS-3 registry), discharged from the same hospital of the Lyubertsy District Hospital (LDH).Material and methods. The study was conducted on the basis of two registries - a retrospective-prospective register LIS (Lyubertsy investigation of death), which was conducted in the Lyubertsy district of the Moscow region, all cases of check-ups in the AMI hospital for a 3-year period (2005- 2007) and the prospective register LIS-3 (11/01/2013 – to the present), which included patients admitted to the cardiology department of the Lyubertsy District Hospital No. 2 with the correct diagnosis of Acute coronary syndrome with and without ST segment elevation. With patients discharged from the hospital, a telephone contact was established no earlier than 1 year after discharge to clarify the life status, and in case of death – to find out its causes. Search for patients who did not answer the phone call, was using by the study of the archive of the polyclinic, with database statistics. Longterm cases of the LIS were compared with LIS-3 registers, clinical demographic characteristics and risk indicators in patients in the LIS and LIS-3 registers were also compared, differences in drug therapy before the onset of AMI and after discharge from the hospital register between LIS and LIS3 were analyzed.Results. Out of 327 patients, the registry included 104 (31.8%) patients discharged in 2014 and 223 (68.2%) in 2018. When comparing the longterm mortality curves of the LIS and LOS-3 registers, a significant difference was noted. The LIS-3 study revealed more frequent referrals for antiplatelet agents (20% vs 16%), statins (11.6% vs 2.0%). Less commonly, diuretics began to be prescribed at the prehospital level. After discharge from the hospital in the LIS-3 registry, a decrease compared to the LIS registry, more frequent prescription of antiplatelet agents (97.5% vs 85.0%), anticoagulants (1.1% vs 0%), statins (96.5% vs 67.0%), beta-blockers (93.3% vs 81.0%). Less commonly, diuretics are prescribed at discharge from the hospital.Conclusion. The present study of the LIS-3 registry showed a significant decrease in the incidence of those who had AMI, which occurred 15-20 years after the LIS registry was conducted.

Nonspecific aortoarteritis (Takayasu's disease) is a systemic inflammatory disease characterized by granulomatous lesions of the aorta and its large branches. The article describes the clinical manifestations, methods of diagnosis and treatment of this pathology. It also describes a clinical observation that illustrates the delayed diagnosis of the disease in a 47-year-old man, where Takayasu arteritis with lesions of the root, ascending aorta, both common carotid arteries, thoracic and abdominal aorta (type V according to the angiographic classification proposed by Moriwaki R.) manifested a syncopal state, just a few days before the development of a life – threatening complication-aortic dissection of type I according to the DeBakey classification. From a clinical point of view, it is important that Takayasu's disease does not always develop in young people, women, and Asian origin, and, unfortunately, it is often very late to diagnose, although the effectiveness of therapy, including surgical correction of this disease, is entirely determined by the timeliness of its diagnosis.

BackgroundTraumatic tracheal injury is a rare type of trauma. In this type of injury, catastrophes may occur owing to a failure to secure the patient's airway. Extracorporeal membrane oxygenation (ECMO) is rescue therapy available for the treatment of urgent cardiorespiratory distress until the patient's vital signs have stabilized. The various applications of ECMO configurations have expanded the scope for this therapy.Case presentationWe describe the case of a 66-year-old man with tracheal rupture with thyroid cartilage fracture due to cultivator handle who was treated with veno-venous ECMO. This case reflects the role and limitations of veno-venous ECMO, in which patient survival was possible with a bi-femoral configuration while also ensuring a clear airway. ConclusionWe shared our experience with bi-femoral veno-venous ECMO as a therapeutic option to contribute to choosing an appropriate approach. Based on our review of the literature, the present case was an uncommon report of survival after tracheal rupture due to trauma without other complications.
