Authors: Martynova Maria , Sultanova Rida , Odintsov Georgiy , Sazgutdinova Regina , Khanova Elvira
Published: May 2020

Tilia cordata Mill. is considered to be the main tree species resistant to urban conditions and it is widely used in the greening of cities. The aim of the study is to assess the patterns of growth and development of small-leaved linden plantations in the urban environment. The research is based on the method of sample areas where continuous enumeration survey has been carried out. The study of urban greening objects was conducted using the methods of landscape assessment and complete enumeration of trees in alley plantings. It was found that Tilia cordata Mill. grows in all districts and zones of the city of Ufa, occupying 34.4% of green areas. During this research it was found that artificially created alley plantings of Tilia cordata Mill. are more well-kept and have well-developed crowns which create a tree shade sometimes 8-10 meters wide (the average crown projection being 7 m). Since alley plantings have repeatedly been pruned, trees in this area are characterized by a large increase in diameter and strong height growth stagnation. Thus, when studying linden plantings of the same age, a sharp difference in the size and shape of trees was observed.

Published: May 2020

Objective

Non-palpable testes remain a diagnostic challenge, often involving exploratory laparoscopy. We evaluated the diagnostic value of a wide range of reproductive hormones in order to distinguish between bilateral cryptorchidism and bilateral anorchia.

Design

In this retrospective study, we identified and included 36 boys with non-palpable testes (20 with cryptorchidism, 3 with congenital hypogonadotropic hypogonadism (CHH), and 13 with anorchia) at first examination during childhood.

Methods

Information on karyotype, phenotype, surgical results from laparoscopy, and biochemistry was retrieved from patient files. We compared serum concentrations of AMH, inhibin B, FSH, LH, testosterone, estradiol, and hCG stimulation testing in cryptorchid and anorchid boys to serum concentrations in a large, age-matched control group. Receiver-operating characteristic curves were used to determine the cut-off values of each reproductive hormone as a predictor of the presence of functional testicular tissue.

Results

Concentrations of AMH in 0–1 year olds: ≥155 pmol/L and >1–15 year olds: ≥19 pmol/L, inhibin B (≥22 pg/mL and ≥4 pg/mL), FSH (≤28.9 IU/L and ≤20.3 IU/L) and hCG-induced testosterone (>1-15 year olds: ≥2 nmol/L) were significantly sensitive and specific markers in predicting the presence of functional testicular tissue in boys with non-palpable testes. In infancy, anorchid infants had significantly elevated gonadotropin levels, while CHH had low levels.

Conclusion

Our findings suggest that laparoscopy may not be necessary in all boys with non-palpable testes if reproductive hormones unequivocally confirm the presence of functional testicular tissue. However, proving the absence may still be a diagnostic challenge.
Expression and steroid hormone regulation of TETs and DNMTs in human endometrium
Authors: Mahajan Vishakha , Osavlyuk Diana , Logan Philip C , Amirapu Satya , Ponnampalam Anna P
Published: May 2020

DNA methyltransferases (DNMTs) and ten-eleven translocation proteins (TETs) facilitate methylation and hydroxymethylation of DNA, respectively. DNMTs are widely studied with conflicting results on their regulation in the endometrium. While the role of TETs in the endometrium remains relatively unexplored. Deregulated expression of TETs and DNMTs are associated with endometrial pathologies. The aim of this study is to characterize the temporal TET expression in endometrium and to determine the hormonal regulation of TETs in comparison to DNMTs. mRNA expressions were quantified by real-time PCR in endometrial tissues from cycling women and localization was determined by immunohistochemistry. Hormonal regulation was investigated in endometrial epithelial and stromal cell lines following a 24 and 48 h treatment cycle. TET1 and 3 mRNA expressions were significantly upregulated in the mid-secretory phase. TET protein expression was ubiquitous in endometrial epithelium throughout the menstrual cycle except during the late-secretory phase, while stromal staining was scattered. TET1 mRNA was significantly upregulated in response to estrogen in stromal cells. Transcriptions of all three TETs were induced in response to progesterone treatment in epithelial cells. Only DNMT3b in epithelial cells and DNMT1 in stromal cells were significantly upregulated upon 24-h estrogen exposure following a significant decrease of DNMT1 when treated with 24 h of estrogen and progesterone. This study suggests that TETs are expressed in a cell-specific, dynamic manner in the endometrium and are responsive to steroid hormones. Investigating the role of TETs individually and with respect to DNMTs, will help to elucidate gene regulatory mechanisms in endometrial biology and pathologies.
The vascular epigenome in patients with obesity and type 2 diabetes: opportunities for personalized therapies
Authors: Costantino Sarah , Mohammed Shafeeq A , Ambrosini Samuele , Paneni Francesco
Published: May 2020

Our genetic background provides limited information on individual risk of developing vascular complications overtime. New biological layers, namely epigenetic modifications, are now emerging as potent regulators of gene expression thus leading to altered transcriptional programs and vascular disease phenotypes. Such epigenetic modifications, defined as changes to the genome that do not involve changes in DNA sequence, are generally induced by environmental factors and poor lifestyle habits. Of note, adverse epigenetic signals acquired during life can be transmitted to the offspring thus leading to premature alterations of the epigenetic and transcriptional landscape eventually leading to early endothelial dysfunction and vascular senescence. Modifications of the epigenome play a pivotal role in the pathophysiology of cardiometabolic disturbances such as obesity and type 2 diabetes. In these patients, changes of DNA methylation and chromatin structure contribute to alter pathways regulating insulin sensitivity, glucose homeostasis, adipogenesis and vascular function. In this perspective, unveiling the ‘epigenetic landscape’ in cardiometabolic patients may help to identify new players implicated in obesity and diabetes-related vascular dysfunction and may pave the way for personalized therapies in this setting. In the present review, we discuss current knowledge of the epigenetic routes implicated in vascular damage and cardiovascular disease in patients with metabolic alterations.
Sociological metatheorising in the 1980s and 1990s: Philosophical aspects of some alternatives to the positivist specification
Authors: Pylypenko Valerii
Published: May 2020

The paper provides a retrospective overview of metatheoretical research unfolding in the 1980s and 1990s. Philosophical aspects of some alternatives to the positivist specification have been analysed. Particular attention has been given to the interpretation of sociological metatheorising as the philosophy of social science (B.Fay). The next step is identification of characteristics related to the conception of metasociology as a dialogue with other social sciences, as well as with political and moral conversations about the social world. This conception was put forward by E.Fuhrman and W.Snizek. The author has also summarised S. Fuchs’s works that describe, compare and analyse cognitive styles of metatheorising in sociology.
Mechanistic perspectives in sociological metatheorising
Authors: Rakhmanov Oleksandr
Published: May 2020

The paper analyses the prospects for sociological metatheorising with regard to social mechanisms and mechanism-based explanations of social reality. The author has done a critical review of the most important works concerning a mechanism-based approach to social phenomena. The following points have been brought into focus: the basic principles of social mechanisms, examples of their use in sociological theories and prospects for their integration into analytical sociology. As analytical constructs, social mechanisms help to draw hypothetical connections between observable events. However, due to multiple definitions of social mechanisms it seems problematic to combine different interpretations of the mechanism-based approach in order to develop a common metatheory. Particular attention is given to J. Coleman’s mechanistic scheme of changes at the macro-level and to the mechanisms of democratisation in Ch. Tilly’s interpretation.
Changes in the attitudes of Ukraine’s citizens towards different types of party systems
Authors: Vyshniak Oleksandr
Published: May 2020

The paper analyses various approaches to measuring the attitudes of Ukraine’s citizens towards certain types of party systems and presents the most reliable indicators for identifying these attitudes in empirical studies. Drawing upon the above-mentioned indicators along with the data of nationwide surveys conducted by the International Foundation for Electoral Systems and a polling company SOCIS during 1997–2000, by the “Democratic Initiatives” Foundation jointly with “Ukrainian Sociology Service”, as well as by the Institute of Sociology of the National Academy of Sciences of Ukraine during 2008–2017, the author tracks changes in respondents’ attitudes towards different party systems. At the moment, the overwhelming majority of Ukraine’s citizens favour a multiparty system with three to five political parties as the most preferable option.
Ethical Issues in Decision-making Regarding the Elderly Affected by Coronavirus Disease 2019: An Expert Opinion
Authors: Martínez-Sellés David , Martínez-Sellés Helena , Martínez-Sellés Manuel
Published: May 2020

The coronavirus disease 2019 (COVID-19) pandemic is resulting in ethical decisions regarding resource allocation. Prioritisation reflects established practices that regulate the distribution of finite resources when demand exceeds supply. However, discrimination based on sex, race or age has no role in prioritisation unless clearly justified. The risk posed by COVID-19 is higher for elderly people than for younger people, so older adults should be prioritised in preventive measures. In the case of people who already have COVID-19, healthcare professionals might prioritise those most likely to survive. Making decisions based on chronological age alone is not justified; in addition to age, other aspects that determine theoretical life expectancy must be taken into account. Individualised correct prioritisation in the allocation of scarce resources is essential to good clinical practice.

Published: May 2020

En este trabajo se desarrollaron tres sistemas de liberación de curcumina (Cur) basados en microfibras de poli(ácido láctico) (PLA, por sus siglas en inglés) obtenidas por electrohilado, con concentraciones de 1, 3 y 5%-P de Cur. La morfología de las fibras fue analizada mediante microscopia electrónica de barrido (SEM) obteniéndose diámetros promedios entre 500 nm y 2.5 μm. La caracterización química se realizó mediante espectroscopia infrarroja con transformada de Fourier (FTIR) y se complementó con espectroscopia Raman, verificando así la incorporación de la Cur en la fibra polimérica. Por otra parte, la caracterización térmica se realizó mediante análisis termogravimétrico (TGA) y calorimetría diferencial de barrido (DSC), las cuales revelaronque la concentración de Cur presente en la fibra afecta la cristalinidad y la estabilidad térmica del PLA. Las tasas de liberación in vitro a pH de 7.4, se determinaron mediante espectroscopia UV-VIS a una longitud de onda de 420 nm y los perfiles de liberación obtenidos se ajustaron con el modelo de Korsmeyer-Peppas. Los resultados del ajuste muestran que la difusión de Cur y la degradación de la matriz polimérica son los principales mecanismos involucrados en la liberación del fármaco.

Authors: Typylo K.
Published: May 2020

Abstract. The main purpose of this work was to describe the karyotype variability of the Ukrainian Mountain-Carpathian sheep breed. Cytogenetic studies were carried out on a group of 25 sheep from that breed. The cultivation of lymphocytes, preparing the cytogenetic samples, classification and registration of chromosome aberrations were held using conventional methods. It was established that the number and structure of the chromosomes of sheep of the Ukrainian Mountain-Carpathian breed correspond to the norm typical for this species of animals. Chromosomal variability of the studied population includes 19.22% of numerical and structural aberrations. By the number and structure of the chromosome set the Ukrainian Mountain-Carpathian sheep breed does not differ from other breeds of sheep. Accurate identification of individual chromosomes with routine coloring allows using cytogenetic studies in breeding practice in sheep breeding.
AN ENZYME-ENHANCED EXTRACTION OF ANTHOCYANINS FROM RED CABBAGE AND THEIR THERMAL DEGRADATION KINETICS
Authors: Tecucianu A-C. , Drăghici O. , Oancea S.
Published: May 2020

There is a great demand for developing efficient anthocyanins extraction related to each plant material. Conventional methods have been replaced by novel techniques, but they might remain attractive when combined with the latter. Anthocyanins extraction from fresh and dried red cabbage was investigated by maceration, ultrasonication, and with enzymes. Pre-treatments through drying determined an improved extraction with respect to fresh samples, freeze-drying emerging as the best method. Combined enzyme-assisted extraction with maceration resulted in higher yield by conducting several extractions (1078.8±12.5 mg/100 g DW). The kinetic studies revealed good stability of anthocyanins at 50 °C, while constant degradation at 80 °C. The rate constant k at 80 °C and pH 3.5 was 1.7 10–3 min–1 and the half-life time t1/2 was 6.7 h. Thermal analysis evidenced heat-induced changes in particular for extracts undergoing pre-heating. These results are valuable for optimal processing conditions of anthocyanins-containing products.

Published: May 2020

Tomatoes (Solanum lycopersicon L.) are one of the most important and most widely consumed vegetables in the world. The fruit contains considerable amount of different phytonutrients such as carotenoids, tocopherols, and vitamin C. In the present work, effects of some abiotic factors on the concentration of phytonutrients were investigated in tomato cultivated in two different types of soil. It was found that the type of soil had slight effect on the most important vital nutrients, while the ecological factors, particularly precipitation and average temperature 3 weeks before harvest, were of significant influence on such nutrients. It was found that low temperature and high precipitation before harvest caused the levels of carotenoids, tocopherol, and vitamin C to significantly increase by 65%, 46%, and 28%, respectively.

Authors: Korkmaz F. Yilmaz , Tuncel N.B. , Özer M. , Tuncel N. Yilmaz
Published: May 2020

Immature rice grain is one of the under-valued by-products of rice milling industry. In this study, it was aimed to investigate the effects of immature rice grain flour (IRGF) substitution to tarhana, which is a traditional cereal-based, fermented food product. IRGF was replaced by refined wheat flour at the levels of 0 (control), 30, 50, 70, and 100%, and the effect of this replacement on the contents of crude fat, ash, protein, dietary fibre, phytic acid, minerals, vitamins B1and B2, tocopherols, γ-oryzanol contents and sensory properties were investigated. It was shown that stabilised IRGF remarkably improved nutritional properties of the end product without adversely affecting sensory quality up to 50%. In conclusion, it could be suggested that stabilised IRGF has a promising potential for many food applications due to being cheap, accessible, nutritious, and gluten-free.

Published: May 2020

Ephemeral social media platforms, which displays rich media, primarily images and videos, are only available only for a short period of time. It has recently attracted researchers ' attention to better understand how ephemeral social media platforms impact users of social media. We design quantitative survey study that sampling data collected over two weeks (N= 149) to understand engagement differences (consuming, participating, producing) between Millennials and Non-millennials (the Silent Generation, the Baby Boomers, Generation X), on one of the leading ephemeral mobile platforms - on Instagram “Stories”. Our data demonstrated that Millennials show statistically significant differences by engaging Instagram “Stories” than Non-millennials. However, results unexpectedly demonstrate that non-millennial (age 40 and more in 2020) users show the same engagement level in “watching” and “reading” ephemeral content as Millennial users.

Background: Recently, a new multicomponent RNA-containing virus was described and called as Jingmen tick virus (JMTV) supposedly belonging to flaviviruses. A virus consists of four viral particles and JMTV was firstly isolated from ticks in China and South America.
Aims: Detection viral RNA specific for JMTV complex, sequencing genome fragments and taxonomy identification novel virus from JMTV complex in patients with Crimean-Congo hemorrhagic fever (CCHF) from southern European part of Russia.
Materials and methods: Panel of 20 randomly selected sera from patients with confirmed Crimean-Congo hemorrhagic fever was collected in 2016 and was used for detection JMTV and CCHF viral RNA by PCR with experimental primers. Subsequent sequencing of isolated fragments of viral genomes was used for identification JMTV and CCHF virus genetic materials and phylogenetic analyses.
Results: The viral RNAs of the CCHF virus and JMTV were detected in blood of four patients. Sequencing of the isolated PCR fragment of S segment CCHF virus allowed identifying these RNA isolates as Europe 1 lineage, subgroups Va and Vb of the CCHF virus that is a typical for the southern European part of the Russia. The nucleotide sequences of segment 2 (GP glycoprotein) of the JMTV were also detected by RP PCR and sequencing in these human sera. The new JMTV isolates were clustered together by phylogenetic analysis. The level of nucleotide identity for newly discovered JMTV isolates was only about 81-82% with comparison to the previously described European variants (Kosovo) of the JMTV.
Conclusions: The results suggest that viral genomic RNA for new multicomponent flavivirus named as Manych virus and related to the JMTV complex was discovered in sera of CCHF patients in Russia.

This article was migrated. The article was marked as recommended. The coronavirus 19 (COVID-19) pandemic affected virtually all activities worldwide. One of them was education, especially Health Sciences. Globally, many medical schools ceased their face-to-face activities and implemented institutional reorganization actions. According to their characteristics and possibilities, institutions adopted diverse strategies and tools to continue providing their services online during this health crisis. These situations implied huge challenges, especially for certain regions, such as Latin America.This article exposes a quick overview of the pandemic experience at the biggest Mexican Med School (UNAM Med School): forecasting, reorganization, actions, challenges, and learnings.Among the most challenging situations experienced were: effective communication strategies; resistance to migrate from face-to-face activities to distance activities; technological development; students and teachers training to implement work and study in virtual spaces; students digital gap; internet and computers access; construction and application of online evaluations; online evaluation of practical skills, and the impossibility of maintaining students in clinical clerkships given the pandemic hazardousness.UNAM Med School was not only reorganized to provide integral care to its community, but it also participated in tasks for the health benefit of Mexico as well as for other countries. We had a huge amount of work, reorganization efforts and creativity resulting in very helpful innovations and new projects.This health crisis showed the best of our community. Actions will remain along the pandemic period and a progressive reincorporation to in-place activities at the end of the health crisis. Some strategies such as virtual activities within teaching, learning, work, evaluation and research will be maintained.When this situation ends, we will hopefully have learned and applied that new experiences to improve our Med School, transitioning into a stronger, more united, and enriched community after the crisis caused by this pandemic.

Some related questions are also discussed.
A remark on prime ideals
Authors: Lee S.C. , Varmazyar R:
Published: May 2020

If M is a torsion-free module over an integral domain, then we show that for each submodule N of M the envelope EM (N ) of N in M is an essential extension of N. In particular, if N is divisible then EM (N ) = N . The last condition says that N is a semiprime submodule of M if N is proper.Let M be a module over a ring R such that for any ideals a, b of R, (a ∩ b)M = aM ∩ bM . If N is an irreducible and weakly semiprime submodule of M , then we prove that (N :R M ) is a prime ideal of R. As a result, we obtain that if p is an irreducible ideal of a ring R such that a2 ⊆ p (a is an ideal of R) ⇒ a ⊆ p, then p is a prime ideal.

The propose of this paper is to extend generalized representations of 3-Lie algebras to Hom-type algebras. We introduce the concept of generalized representation of multiplicative 3-Hom-Lie algebras, develop the corresponding cohomology theory and study semi-direct products. We provide a key construction, various examples and computation of 2-cocycles of the new cohomology. Also, we give a connection between a split abelian extension of a 3-Hom-Lie algebra and a generalized semidirect product 3-Hom-Lie algebra.

Entre sintomas e textos literários: a Psicanálise e a escolha dos nomes literários
Authors: Craia Eladio C P
Published: May 2020

o presente artigo analisa a singularidade epistemológica que implica a utilização, tanto por parte do âmbito médico-psiquiátrico-, quanto, - e especialmente-, da psicanálise, dos nomes próprios de Sade e de Sacher-Masoch, autores oriundos da literatura não da medicina, nas suas tabelas sintomatológicas. Os nomes de Sade e Masoch identificam determinadas condições psíquicas bem conhecidas, assim como ajudam a organizar uma taxonomia do campo das perversões: o sadismo e o masoquismo. O texto aborda dois tópicos conceituais que se derivam desta escolha epistemológica: o primeiro visa determinar quais condições e caraterísticas muito específicas estas sintomatologias devem possuir para que não poderem ser nomeadas, como habitualmente, com os nomes dos médicos que reconhecem e isolam o conjunto sintomático. O segundo tópico analisa certo uso não literário que a psicanálise propõe destes sintomas nomeados por literatos, em particular a afirmação da necessária constituição de um complexo sadomasoquista. Neste sentido, o artigo verifica que, se levadas em consideração as literaturas de Sade e de Masoch, - no que elas expõem sobre tipos psíquicos e sobre produção desejante-, este complexo, esta reunião, não seria possível. A psicanálise reuniria o que a literatura, com tanto cuidado diferenciou. Para levar adiante esta reflexão, o texto acompanha a leitura que Gilles Deleuze propões da obra de Sacher Masoch, no seu texto, Apresentação de Sacher-Masoch: o frio e o cruel.
TEORIAS DA TRANSFORMAÇÃO SOCIAL: PARADIGMAS POSITIVISTAS E MARXISTAS EM DEBATE
Authors: Favoreto Aparecida , Galter Maria Inalva
Published: May 2020

Diante da diversidade e complexidade em torno do debate sobre a transformação da sociedade, o presente artigo objetiva explicitar as compreensões positivistas e marxiana sobre o tema, com base nas obras de Auguste Comte (1798 – 1857), Émile Durkheim (1858 – 1917), Karl Marx (1818 – 1883) e Friedrich Engels (1820 – 1895). Apresenta-se o ponto de vista desses autores acerca de ciência, de sociedade, do homem/indivíduo, do Estado e da educação. Não se trata de um inventário de suas ideias, mas, o de traçar algumas comparações entre as concepções desses autores, com a finalidade de explicitar os fundamentos de suas divergências. Destaca-se que as divergências entre essas duas correntes ultrapassam o conteúdo e se revelam em uma concepção de história, traduzindo-se em perspectivas políticas, ideológicas e educacionais. Evidencia-se que formas diferentes de ver o mundo impõem compreensões diferentes sobre a atuação humana.
APRESENTAÇÃO DOSSIÊ: HISTÓRIA E HISTORIOGRAFIA NA EDUCAÇÃO: CONTRIBUIÇÕES DOS CLÁSSICOS
Authors: Favoreto Aparecida , Schlesener Anita Helena , Carola Joseph
Published: May 2020

O Dossiê História e historiografia na educação: contribuições dos clássicos surgiu de dois interesses: o primeiro foi o de contribuir com os debates sobre a educação, isto, tanto no aspecto de reunir reflexões sobre o processo histórico como o de expor diferentes interpretações sobre a História e a Educação. O segundo, interligado a este, foi o interesse em recuperar as contribuições dos clássicos. No caso, ainda que não sejam reflexões contemporâneas, a recuperação se constitui com a perspectiva em apresentar como a educação já foi pensada em diferentes contextos sociais.
HISTÓRIA, POLÍTICA, EDUCAÇÃO: UMA ABORDAGEM DA PERSPECTIVA DO MATERIALISMO HISTÓRICO
Authors: Schlesener Anita Helena , Da Silva Adnilson José , Sandeski Vicente Estevam
Published: May 2020

Este artigo retoma alguns fragmentos dos escritos de Antonio Gramsci e de Walter Benjamin para algumas reflexões sobre a articulação entre história e política, com desdobramentos na educação. Embora sejam clássicos da filosofia voltados a entender as contradições de seu tempo, estes autores nos mostram que, no curso da história moderna, a cultura dominante marginaliza a cultura das classes populares, apaga do seu imaginário o significado político e histórico do seu pensamento, das suas lutas e de suas ações coletivas, tanto no seu caráter específico e popular quanto em sua forma de resistência. De forma introdutória, visto a profundidade e extensão da produção intelectual destes autores, salientamos a importância da história e da historiografia da perspectiva do materialismo histórico.
Técnicas argumentativas e a construção do ethos discursivo: análise do processo judicial condenatório de Frei Caneca
Authors: Santos† Ivanaldo Oliveira dos , Da Silva Moura Alex Sandra , Alves Monteiro Samuel
Published: May 2020

Este estudo tem como objetivo identificar, por meio das técnicas argumentativas empregadas no processo judicial condenatório de Frei Caneca, o ethos discursivo presente na construção de sua defesa. A base teórica está apoiada na abordagem da nova retórica, representada por Perelman e Olbrechts-Tyteca (2005), e os estudos sobre ethos discursivo em por Maingueneau (2002, 2004, 2008, 2014). O corpus deste estudo é composto por três excertos da defesa proferida pelo Frei Caneca em seu processo judicial condenatório datado de 1824. A análise mostrou uma presença de três técnicas de argumentação da nova retórica, o que resultou na construção de um tipo de ethos discursivo que permeou o corpus, que foi o ethos pré-discursivo construído na previsibilidade do interesse do auditório em condená-lo antecipadamente e o ethos dito, quanto ao uso de metáforas ou de alusões a outras cenas de fala, presentes na defesa de Frei Caneca.
“Jesus é travesti”: um olhar sobre a LGBTfobia em discurso polêmico no Instagram
Authors: Cunha Andréa Mendonça , Pereira Curado Mariano Márcia Regina
Published: May 2020

Neste artigo visamos à análise de uma publicação do cantor Johnny Hooker em seu perfil no Instagram e de alguns comentários feitos por seus seguidores. Seu discurso, ainda que não explicitamente, mostra-se como nota de repúdio ao cancelamento da apresentação da peça “O evangelho segundo Jesus, rainha do céu”, protagonizado pela atriz transexual Renata Carvalho, em que Cristo é representado como uma travesti, no Festival de Inverno de Garanhuns 2018. Em nossa análise, destacamos as estratégias argumentativas mobilizadas pelo cantor em defesa do espetáculo (escolhas lexicais, intertextos, figuras etc) e ainda aquelas às quais recorreram seus seguidores em comentários polêmicos contra o posicionamento do artista, como o uso do argumento ad hominem, que revelou discursos lgbtfóbicos. Para atingirmos nosso objetivo, recorremos a estudos (neo)retóricos, argumentativos e discursivos, como os de Aristóteles (2011), Perelman e Olbrechts-Tyteca (2005) e Maingueneau (2001), além de Butler (2004), para as questões de gênero e sexualidade.
As figuras retóricas e as paixões numa decisão do judiciário brasileiro
Authors: Butieri Kathrine , Lérco Camila Cesário
Published: May 2020

Este texto analisa a argumentação, sob a perspectiva dos estudos retóricos, numa decisão do STJ/SP de 2010, em que o órgão julga a improcedência da ação proposta pela Companhia de Bebidas das Américas (AMBEV) em face da Fundação de Proteção e Defesa do Consumidor (PROCON), em reforma da decisão por meio da apelação que dispõe sobre a campanha publicitária televisiva “Musa do Verão”. O principal objetivo é correlacionar retórica e direito na decisão do judiciário contemporâneo e observar seus efeitos de persuasão no auditório. Com fundamento em Chaïm Perelman e em seus estudos da Nova Retórica sobre o modo como o auditório se constitui – partes em litígio, operadores do direito e opinião pública –, encontramos as bases do discurso de juízes que utilizam técnicas retóricas. O aporte teórico empregado se compõe principalmente de Aristóteles (2011), Perelman (2010), Perelman e Olbrechts-Tyteca (2014), Meyer (2007, 2018), Amossy (2017) e Ferreira (2015).

Revisitando o Triunvirato lógica/dialética/retórica
Authors: Johnson Ralph
Published: May 2020

Muitos teóricos da argumentação adotaram a visão de que a argumentação pode ser abordada sob três perspectivas diferentes: a lógica, a dialética e a retórica, às quais denomino Triunvirato. Segundo Wenzel (1990), a base conceitual para esse triunvirato é a distinção entre argumentação como produto, como processo e como procedimento (a Distinção Tripartite). Neste artigo, quero levantar questões sobre a Visão do Triunvirato e a Distinção Tripartite na qual ela se baseia.
Legal nature of the impermissibility warning violations of requirements in the fuel and energy sector
Authors: Otcheskaya T. I. , Afanasieva T. I.
Published: May 2020

In the context of protecting the rights of entrepreneurs, the authors investigate the problem of determining the legal nature of such an act of reaction to an offense as a warning. The lack of a proper understanding of the nature of the warning determines the problems associated with the announcement of the warning, provided for By the law on the Prosecutor’s office and various Federal laws. Analysis of the practical implementation of these rules has shown a lack of necessary clarity and unambiguity of the regulations. The lack of a unified doctrinal approach to understanding the essence of the warning against violation of requirements is another confirmation of this. Having identified and analyzed the essential properties of the warning and its basis, the authors conclude that by its legal nature, the warning is a nonnormative legal act and can be challenged in court, which is confirmed by relevant examples of judicial and prosecutorial practice. Current legal provisions that obscure the obligation of the addressee to comply with the warning are subject to adjustment in order to ensure legal certainty.
Generalidades de la Pandemia por COVID-19 y su asociación genética con el virus del SARS

Un síndrome respiratorio de causa desconocida causó un brote que alertó a los habitantes de Wuhan, China a finales de 20191. Dado el carácter inusitado de la enfermedad, la falta de información clínica, el desconocimiento de la frecuencia, distribución y el potencial de diseminación de la enfermedad, las autoridades sanitarias chinas llevaron a cabo una investigación exhaustiva que para el 7 de enero de 2020 les permitió caracterizar un nuevo coronavirus al cual posteriormente la OMS nombró oficialmente como COVID-192,3. Con la secuenciación del genoma de este virus se desarrollaron pruebas diagnósticas de biología molecular tipo RT-PCR que permiten la correcta identificación y el aislamiento de los pacientes infectados para brindarles un tratamiento adecuado, además de hacer un seguimiento de los posibles casos infecciosos4. Hasta el 12 de enero de 2020 todos los casos confirmados se limitaban a la ciudad China de Wuhan. Con el fin de contener la infección por el COVID-19 y reducir la propagación a otros países, la ciudad de Wuhan suspendió el transporte público, con el cierre de aeropuertos, estaciones de ferrocarril y autopistas en la ciudad, conteniendo a más de 11 millones de personas5, sin embargo, para el 22 de enero del 2020 ya se había confirmado por lo menos un caso de COVID-19 en Tailandia, Japón y Corea del Sur6-8.

Published: May 2020

Introducción: La vida universitaria trae consigo cambios en el estilo de vida, principalmente porque las conductas asumidas durante esta etapa son consideradas no saludables, situación preocupante para el desarrollo a temprana edad de enfermedades no transmisibles. Objetivo: Caracterizar los factores riesgo asociados al estilo de vida y a las enfermedades no transmisibles de los estudiantes de la facultad de ciencias contables, económicas y administrativas de una universidad pública del Cauca. Materiales y métodos: Estudio analítico de corte transversal, realizado a 99 estudiantes universitarios a quienes se les indagó por las características sociodemográficas, académicas, antropométricas y factores comportamentales asociados a enfermedades no transmisibles, basándose en los pasos 1 y 2 del instrumento STEPS validado por la Organización Mundial de la Salud. Resultados: Se encontró unpromedio de edad de 22,5 años, un índice de masa corporal normal para ambos sexos y un índice cintura cadera que muestra mayor porcentaje de riesgo en el género femenino; se encontró un alto consumo de alcohol (n=60), los estudiantes consideraban tener un estilo de vida sedentario (n=53), no fumaban (n=88) y no consumían frutas y verduras (n=74), mientras que se encontró relación estadísticamente significativa entre sexo y motivos de diversión para consumir bebidas alcohólicas (p=0,039). Conclusión: Los hallazgos muestran una población universitaria vulnerable para sufrir de enfermedades no transmisibles debido a su percepción de vida sedentaria, la poca ingesta de frutas y verduras, el consumo de alcohol; conductas preocupantes que deben ser controladas a partir de propuestas de intervención que fomenten estilos de vida saludables.
