The aim of the study was to analyze our own experience of using the lateral approach in knee joint arthroplasty in children with oncopathology. Materials and methods of research: the results of a retrospective nonrandomized uncontrolled single-center study are analyzed, within the framework of which 97 endoprosthetics of the knee joint were performed in children and adolescents with oncological pathology over 7 years (2012–2018). Lateral approach was used in 28 patients. The functional results were assessed using the MSTS rating scale 6 and 12 months after the surgery. Postoperative complications were analyzed according to the Henderson classification (modified by the ISOLS committee). Results: when comparing the functional outcome depending on the surgical approach, no statistically significant difference was found either after 6 months (p=0,124) or after 12 months (p=0,755). There is no more frequent development of complications detected (p=0,551). The access used also did not affect overall survival in osteosarcoma (p=0,577), in Ewing's sarcoma (p=0,493), as well as on event-free survival in osteosarcoma (p=0,829) and in Ewing's sarcoma (p=0,886). Conclusion: the use of the lateral surgical approach for knee arthroplasty in children with oncopathology does not affect the treatment results, however, it provides the surgeon with greater variability of actions during preoperative planning. This is especially true for patients whose biopsy tract is located on the lateral side.

Chordomas are rare malignant tumors that account for no more than 4% of primary bone tumors. The incidence of chordomas in children does not exceed 5%. Tumor removal is the primary method of treatment, however, due to the high frequency of non-radical surgery, most patients require an adjuvant course of radiotherapy. Photon radiation therapy in doses of 50–60 Gy does not provide the required antitumor effect. At the same time, the use of a proton beam allows delivering a dose of 72 Gy or more with low toxicity. The article presents 4 clinical case reports of base-skull chordoma in children describing their own experience with proton therapy. An analysis of radiation exposure plans was carried out, with an evaluation of the main qualitative indicators characterizing the high-dose coverage of tumours and the radiation load on healthy tissues. The case reports described confirm that the technique of proton irradiation with a pencil beam makes it possible to safely administer ultra-high doses of radiation in close proximity to healthy tissues, including in children. Further improvement of the irradiation planning technique is required, which will improve the target coverage with a high dose of ionizing radiation.

Every year, 1,700–1,850 pediatric patients apply to the Department of Toxicology of Filatov Children's City Clinical Hospital for specialized medical care. More than 56% of hospitalizations are caused by medicinal poisoning. One of the serious complications of drug intoxication is acute kidney injury (AKI). The incidence of AKI in acute chemical poisoning in childhood is from 10 to 57,6% according to various authors, therefore, the issues of effective treatment of AKI in the medical practice of doctor of any specialty are extremely relevant. The article presents the case of conservative treatment of AKI stage 3 according to the KDIGO classification in a teenager with metamizole poisoning, including inclusion of «Cytoflavin» cellular energy protector as a part of complex therapy. As a result of the treatment, the level of proteinuria and azotemia in the child has decreased. The rate of tuber filtration has increased from 20,0 to 62,4 ml/min/1,73 m2. Thus, the use of a cellular energy protector contributed to effective restoration of renal function.

The proven relationship between the frequency of influenza and acute respiratory infections in children with vitamin D deficiency and the data on the relationship between a high mortality rate from SARS-CoV-2 in patients with low levels of vitamin D in the body under conditions of a forced sharp decrease in the level of insolation in the period from March 11, 2020 dictated the relevance assessing the vitamin D supply of children and adolescents in educational organizations of the city of Ulan-Ude. Purpose of the study: to assess the vitamin D supply of children and adolescents living in the city of Ulan-Ude. Methods: in a non-randomized, single-center, transverse (one-stage) uncontrolled comparative study, the concentration of 25(OH) vitamin D – 25(OH)D – in the blood serum of children and adolescents in Ulan-Ude was studied from May 22 to May 24, 2020. Moderate vitamin D deficiency (deficiency) was determined when the content of 25(OH)D was in the range of 20–30 ng/ml, the deficiency was within the limits, and the severe deficiency was <10 ng/ml. Results: assessment of vitamin D provision was carried out in 60 children aged 10 to 17 years (15 [11; 16] years), of which 19 boys, 41 girls. Children were divided into 2 groups depending on age: 10–11 years old (grade 5) (n=27) and 15–17 years old (grades 9–11) (n=33). Deficiency of vitamin D was found in 4 (15%), 11 (33%); deficit – in 19 (70%), 18 (55%); severe deficiency – in 2 (7%), 4 (12%), respectively. Along with low indicators of the provision of children and adolescents in the city of Ulan-Ude, an even lower provision of children and adolescents of Buryats was noted. The concentration of vitamin D in Buryat children and adolescents below normal (less than 30 ng/ml) was found in 35 (100%) children and adolescents, deficiency – in 8 (23%) children, vitamin D deficiency – in 21 (60%) children and severe deficiency – in 6 (17%). A statistically significant difference in the content of 25(OH)D between children and adolescents of Russian nationality and Buryats was revealed (p=0,0056). Evaluation of the diet showed that the frequency of consumption of fish as a source of vitamin D by children and adolescents is low. Conclusion: there is a high incidence of vitamin D deficiency and deficiency, which amounted to 97% in the examined children and adolescents living in the city of Ulan-Ude, more pronounced in Buryat children and adolescents, which requires organizational measures to replenish the vitamin D deficiency.

Extracorporeal photopheresis (ECP) has proven effectiveness for treatment of several diseases, including acute and chronic graft-versus-host disease (GVHD) after allogenic transplantation of hematopoietic blood stem cells. The standard ECP requires leukapheresis to obtain a mononuclear cell fraction. The possibility of using leukapheresis is limited by the requirements for vascular access and the somatic status of the patient. There is a relatively new method of performing ECF, called «mini-photopheresis» (mini-ECF), in which a fraction of mononuclear cells is isolated from a dose of whole blood obtained by the exfusion method. The article presents preliminary results of using mini-ECP in patients with acute and chronic GVHD. Materials and methods of research: the study included 11 patients with acute (7 patients) and chronic (4 patients) GVHD who received mini-ECP therapy from June 2018 to January 2021. Leukocyte fractions rich in mononuclear cells were prepared from the dose of whole blood of patients. The resulting fraction was diluted with 0,9% NaCl solution to less than 3% hematocrit. The cellular product was then injected with an 8-Methoxyperalene and programmed with UV spectrum A. Autologous erythrocytes and the finished cellular product were injected into the patient after irradiation. Results: 6 out of 7 patients (85,7%) with acute GVHD has responded to mini-ECP therapy. In patients with chronic GVHD, the response rate to mini-ECP therapy was 25%. In both groups there are no significant differences found in the number of leukocytes count per body mass in the finished cellular product. The correlation between the presence and severity of response to mini-ECP therapy with the number of leukocytes in the finished cellular product was not determined. None of the patients had adverse reactions and complications associated with mini-ECP therapy. Conclusion: mini-ECP is an attractive alternative for treatment of patients with steroid-resistant or steroid-dependent GVHD who cannot undergo leukapheresis. Our results are preliminary, but promising. We will continue to use this method as a second-line therapy for patients with contraindications to leukapheresis.

Authors: Cleave Peter
Published: May 2021

The argument in the last part of the Two Suns? series was summed up as follows. There are several spaces or forms of space involved; territorial space, outer space, cyberspace and living space, And there is data to be found and owned in each of these spaces. That data may be processed using algorithms in each space and across all spaces.

The argument has been developed as follows. In Part One, the bones, at least some of them, of the argument in the series may be seen in the title,

Two Suns? The State of Amazon? Bezonomics, market control and the algorithmic state. Books by Brian Dumaine and Rob Hart, Bezonomics and The Warehouse respectively, were the jump off points for the discussion along with earlier work by me on incipient states. I asked about Amazon:

Is it an entity that now has a force, a scale, an ethic and a set of borders that speaks of a state-like situation wherein people rely and trust Amazon to fulfil their needs?

El artículo analiza la representación política descriptiva y simbólica de las mujeres que ocupan cargos en los cabildos de municipios con Sistemas Normativos Indígenas (SNI), en el estado de Oaxaca, México. Plantea que si bien se ha registrado un incremento histórico en el número de nombramientos (representación descriptiva), la mayor parte corresponden a cargos relacionados con el cuidado y el servicio familiar, lo cual es analizado desde la perspectiva comunitaria indígena, así como de su posible implicación en la reproducción de las relaciones de poder caracterizadas por la desigualdad de género (representación simbólica). A partir del contexto jurídico y social en que se ha desarrollado el proceso de paridad de género, se analizan los resultados obtenidos en las elecciones de 2016 y 2019, y se compara, entre estos años, el número de presidentas municipales y síndicas nombradas en los 417 municipios con reconocimiento de su libre determinación para elegir a sus cabildos, así como el tipo de regidurías mayormente ocupadas por las mujeres. Estos datos se observan desde los argumentos de algunos actores que permiten explicar los roles que tienen las mujeres en la vida política de las comunidades indígenas oaxaqueñas.
Ser-se estrangeiro: forjas (a)poéticas de desterritorialização
Authors: Augusto da Silva Lucas
Published: May 2021

A partir de um quadro teórico que conjuga o conceito de \textit{desterritorialização} tal qual desenvolvido por Gilles Deleuze e Félix Guattari, e da teoria a-poética de Charles Bernstein, analisa-se três movimentos de fuga à territorialidade, permeados pelos processos de colonização moderna e globalização contemporânea, debruçando-se sobre três bases literárias. Primeiro intenciona-se analisar como este processo ocorre na relegação da condição de estrangeiro aos nativos de um território na exploração colonial com enfoque no conto "A legião estrangeira" de Clarice Lispector; depois, investiga-se o movimento de globalização pela consolidação da língua inglesa como padrão comunicacional pela análise crítica de poemas de Paulo Leminski e José Brites; finalmente, a partir de uma leitura dos poemas que compõem "Mapas de Viagem" de Frederico Barbosa, conclui-se sobre os hiatos da composição de uma identidade nacional gerados pelas desigualdades e mazelas internas deflagradas no caso brasileiro.
Orlanda Amarílis, Vera Duarte e Dina Salústio: a tessitura da escrita de autoria feminina na ficção cabo-verdiana

Published: May 2021

A escrita de autoria feminina, em especial das escritoras cabo-verdianas Orlanda Amarílis, Dina Salústio e Vera Duarte, contribui para a construção da identidade cabo-verdiana e caminha na direção da contestação da violação de direitos, sobretudo, da mulher. Objetivou-se perscrutar, a partir da tessitura da escrita de autoria feminina, a construção de uma literatura que, ao focar o olhar nas mulheres, para além de, inicialmente, intentar rasurar o ideal colonialista, pautado em uma estrutura patriarcal, expõe, repisa, denuncia, e ressignifica a realidade das mulheres em contextos de opressão. Dessa maneira, a escrita de Amarílis, de Duarte e de Salústio irrompem as fronteiras cabo-verdianas para abarcar "vozes-mulheres" outras que, pelos caminhos da literatura, desconstroem violências estruturais e reconstroem identidades silenciadas.
Literatura e arte indígena no Brasil

O texto apresenta um breve panorama da arte e literatura indígena no Brasil, desde a chegada de Cabral até os dias atuais. Considerando que, por muitos séculos, os povos indígenas foram invisibilizados das mais diversas formas, inclusive pela cultura hegemônica "branca", que sempre ditou o cânone no Brasil, o artigo aborda a construção do "índio" na cultura brasileira, passando pelo Indigenismo e pelo Modernismo, e se concentra nas vozes indígenas que começam a (in)surgir com mais força a partir dos anos 2000: Ailton Krenak, Daniel Munduruku, Eliane Potiguara, Denilson Baniwa, Jaider Esbell, entre outros. Vozes que reivindicam o lugar que lhes foi negado na sociedade brasileira, um lugar de direito à vida, à arte e à cidadania, um lugar que aponta para novas narrativas, cada vez mais necessárias.

COVER CROPS AND SOIL-BORNE FUNGI DANGEROUS TOWARDS THE CULTIVATION OF Daucus carota L.
Authors: Patkowska Elżbieta
Published: May 2021

The principles of good agricultural and horticultural practice, which considers both environmental protection and high yielding of plants, require modern methods of cultivation. Cover crops are used in the cultivation of various plants, including root vegetables such as carrot. The purpose of field and laboratory studies was to determine the effect of selected cover crops on the healthiness of carrot (Daucus carota L.). The field experiment took into consideration cover crops such as spring rye, white mustard, buckwheat, fodder sunflower and two systems of soil tillage, i.e.: tillage before winter (ploughing) + spring tillage (a combined cultivator) and only spring tillage (a combined cultivator). In each experimental treatment, the number and healthiness of carrot seedlings were determined. A laboratory mycological analysis made it possible to determine the qualitative and quantitative composition of fungi infecting the underground parts of carrot. Good emergencies and the healthiness of carrot plants were observed in the objects with rye and white mustard as cover crops. The cultivation system had no significant effect on the proportion of diseased seedlings of carrot. Rye and white mustard were more effective than buckwheat and sunflower in limiting  the occurrence of fungi pathogenic towards carrot. Diseased seedlings and roots after harvest of carrot were most frequently colonized by Altenaria alternata, A. chartarum, A. dauci, A. radicina, Sclerotinia sclerotiorum, Rhizoctonia solani and Fusarium spp.
THE IMPACT OF PLANT MATERIAL FREEZING AND EXTRACTANT ACIDIFYING ON THE ANTIOXIDANT POTENTIAL AND PIGMENTS CONTENT IN EXTRACTS AND RAW MATERIALS OF DIFFERENT CARROT VARIETIES
Authors: Muzykiewicz-Szymańska Anna , Zielonka-Brzezicka Joanna , Klimowicz Adam
Published: May 2021

The antioxidant activities of extracts of purple, yellow and orange carrot varieties were evaluated by in vitro methods i.e. DPPH, ABTS, FRAP, and CUPRAC. The total polyphenols concentration was evaluated using Folin-Ciocalteu technique. The content of anthocyanins, chlorophylls and carotenoids was evaluated in fresh and frozen carrots. The anthocyanin concentration was also determined in carrot extracts. The effect of certain parameters of ultrasound-assisted extraction, i.e. extraction time, concentration and acidifying of extractant, as well as the type of raw material (fresh or frozen) was analyzed. The antioxidant potential as well as content of polyphenols and plant pigments were the highest in purple carrot extracts. The most effective extractant seems to be 70% (v/v) ethanol. The extension of the extraction time, in majority of cases, led to an increase of antioxidant activity of extracts, whereas the freezing of raw material generally decreased the above-mentioned activities. The effect of acidification of extractant is ambiguous and depends on the method applied to evaluate antioxidant activity.

The natural and ubiquitous production of figs throughout Turkey makes it one of the most important centers of fig genetic resources. The current study aims to determine the most important phytochemical ingredients of a local variety of fig (Ficus carica L.) collected from the natural habitats in the province of Kahramanmaras at different harvest intervals in 2018. The fruit samples were assayed for various metabolites such as phenolic compounds, total phenols (TP), total flavonoids (TF), total anthocyanins (TA) and total antioxidant capacity (TAC). The results showed that epicatechin (7.809 mg/100 g FW) was dominant phenolic compound in the fruits of this variety, followed by myricetin (2.632 mg/100 g FW), kaempferol (2.396 mg/100 g FW) and quercetin (0.655 mg/100 g FW). The average values obtained for TP, TF, TA, and TAC were found to be 135.71 mg GAE/100 g FW, 188.20 mg/100 g FW, 54.65 ml/L, and 14.34 DPPH%, respectively. There were also observed significant differences in total polyphenolic, flavonoid, anthocyanin content, and the antioxidant capacity at different harvest periods. The current findings indicate that the fig variety explored has a high antioxidant activity and is rich sources of anthocyanins and phenolic content. This study provides valuable information about the health benefits of figs endorsed by the phytochemical characteristics.

Introduction: In order to build a quality inclusive environment (not only in education) it is not enough to have material and personal capacity. The students themselves also need to be included via quality assessment of this environment. Research focused on the attitudes of university students with special educational needs (SEN students) towards the inclusive environment quality at a specific educational institution in Slovak conditions has never been done before.

Methods: The research team aimed to identify SEN students’ attitude (N=20) to the quality of inclusive university environment. To maintain anonymity, university will not be specified; as for students, only their degree of study and gender will be listed instead of their age (65% were females). An attitudinal questionnaire developed by the authors was used to identify how the respondents perceived the quality of inclusion in the respective university environment.

Results: SEN students’ attitudes show the highest score in emotional components (AM=3.607; SD=0.602). Additionally, there is a statistically significant relation between their attitudes and the coordinator’s work quality. A statistically significant difference was measured between the attitudes of those SEN students who were satisfied with the work of their coordinator and those who were not (p-value 0.008). We noted a strong deviation in favour of the satisfied students.

Discussion: SEN students generally perceive the inclusive environment at the faculties at which they are currently studying as positive, which can result from the fact that coordinators are appointed specifically to cater to their needs. A distance course has also been created to improve the inclusive environment for students; it helps to improve the effectiveness of communications between coordinators and students, and quickly resolve any issues related to education.

Limitations: Both the size of the research sample and the fact that the survey was conducted at only a single university were limiting factors. Thus, we cannot generalize our findings to the entire university SEN student population nor to all Slovak universities.

Conclusions: In the conditions of the institution in question no research of this nature has ever been done before. In order to increase the internal quality of the school environment a reflection on the inclusive environment quality from SEN students is necessary. Looking forward, we recommend carrying out a more detailed observation of the inclusive environment quality in relation to the coordinator for students with special educational needs (hereinafter SSEN coordinator), their work quality and expertise.

Introduction: This article examines the first level of the European higher education system, namely the short-cycle higher education trainings related to the ISCED 5 whose Hungarian characteristics, and its historical changes were described.

Methods: We examined participation rates among OECD countries. As there are large differences in the short-cycle higher education trainings in Europe, we have relied on data that makes the different systems comparable.

Results and discussion: The interpretation, definition and practical orientation of the trainings varies from country to country, we presented the Hungarian form in connection with the results of international comparative studies and data. To understand the role of trainings, it is essential to get to know their history, especially because short-term higher educational trainings were transformed in several European countries.

Conclusions: Prioritising or effacing the social-political role of short-cycle higher education trainings depending on the political orientation of the government and as a part of this, prioritising the disadvantaged regions instead of the disadvantaged students.

Food production is connected with a negative effect on the environment as it is linked with the utilisation of natural resources such as fresh water and with the emission of greenhouse gases (GHGs). It is, therefore, very important to prevent the wastage of food at all food chain stages. Special attention should be paid to the phenomena which burden the environment in an unjustified way. One such example may be the waste of final products at the stage of retail sale objects. The purpose of the present paper was to estimate the effect of wasted food in the selected network of the retail sale on the environment with the application of water footprint indicator and CO2 emission. On the grounds of the collected data, the participation of food withdrawn from the trade, the reasons for the mentioned phenomenon and the size of the wasted food products and those donated to charities were established. Based upon such data, the level of CO2 emission and the water print of the products which have not been utilised according to their destination were estimated. In spite of the fact that the animal origin products were characterised by a small participation in the weight of the unsold food (ca. 13.34% annually), they constituted the main source of CO2 emission and water footprint estimated from the food waste. It was calculated that the annual turnover and waste of the products only in one trade network was connected with the unjustified emission of ca. 12 thousand tonnes of CO2 and 13 million m3 of water footprint.

Bezbednost i zdravlje na radu jeste obezbeđivanje takvih uslova na radu kojima se, u najvećoj mogućoj meri, smanjuju povrede na radu, profesionalna oboljenja i oboljenja u vezi sa radom i koji pretežno stvaraju predpostavku za puno fizičko, psihičko i socijalno blagostanje zaposlenih.Opšti cilj sistema bezbednosti i zdravlja na radu u Republici Srbiji je da se za svakog radnika prepoznaju svi rizici na radnom mestu i u radnoj okolini, na osnovu identifikovanih opasnosti i štetnosti i u skladu sa sistematizacijom radnih mesta.Opasne supstance mogu biti hemijske ili biološke prirode. Ponekad može biti očigledno da postoji potencijal za izlaganje opasnim supstancama. Međutim, to nije uvek slučaj. Neke naizgled bezopasne supstance, poput prašine brašna, mogu prouzrokovati štetu prilikom izlaganja na radnom mestu. U naizgled normalnim, svakodnevnim predmetima mogu biti prisutni opasni nivoi štetnih materija.Jasno je da je od velike važnosti adekvatna kontrola izloženosti radnika tim supstancama. To se oslanja na postizanje i održavanje odgovarajuće kontrole izloženosti i zahteva stepen kompetencije i stručnosti. Uz pravilnu upotrebu kontrola izloženosti, rad se može izvoditi čak i sa jako toksičnim supstancama, bez rizika za zdravlje radnika.Azbest je mineral koji se javlja u prirodi čija se vlakna mogu izdvojiti u tanke i trajne niti. U širokoj je uporabi u industriji jer su vlakna koja ga čine izvrsni izolatori (otporni su na toplinu, vatru i hemikalije i ne provode električnu energiju). Često se koristi za ojačanje cementa i drugih materijala kao što su izolacione ploče, valovite krovne ploče, cementni oluci i cevi. Azbestni premazi su se koristili kako bi se izolovala buka. Azbest je imao široku primen zbog svojih dobrih osobina i zbog toga je svuda zastupljen.

Published: May 2021

Sve veći razvoj ljudskog drušva i industrije neminovno dovodi do prekomernog ispuštanja zagađujućih materija u sve medijume životne sredine između ostalog i u akvatične sisteme. Iz tog razloga je od velike važnosti monitoring životne sredine. Postojeće metode ispitivanja imaju određene mane i ograničavajuće faktore primene. Iz tog razloga se sve više pažnje posvećuje razvoju novih, pouzdanih i preciznih uređaja kao što su optički senzori. Osnovni cilj rada jeste optimizacija odnosno primena kolorimetrijskog fiber optičkog senzora za određivanje hlora u uzorcima vode.
