NARRATIVAS DE INDÍGENAS DE DIFERENTES ETNIAS: O LETRAMENTO ACADÊMICO EM LÍNGUA PORTUGUESA

Esse estudo discute questões relacionadas ao processo de aquisição de práticas sociais de letramento acadêmico em português, por estudantes indígenas das etnias Guarani e Terena que pertencem à Reserva Indígena Francisco Horta Barbosa, em Dourados/MS. Ao acessar o sistema educacional acadêmico, esses estudantes se deparam com críticas de que sua escrita não condiz com a expectativa padrão da língua aceitável no meio universitário. Isso faz com que esses estudantes engrossem as estatísticas dos chamados ‘sub-representados’. Para respaldar essa discussão, utilizamos teóricos como Street (1984, 2000), que contrapõe dois modelos de letramento. O primeiro modelo, Modelo Autônomo centra-se em propósitos político-ideológicos próprios de uma perspectiva do mundo ocidental, cuja educação tem por base o neoliberalismo. O segundo modelo, dito Modelo Ideológico se delineia sobre a perspectiva da inserção do contexto sociocultural dos seus praticantes. Este estudo investiga a prática de letramento enquanto competência e habilidades de escrita indígena em língua portuguesa. O corpus do estudo constitui-se da escrita de dois textos de alunos indígenas, denominados de narrativas indígenas, tendo em vista seus diferentes eventos/práticas de letramento. Os dois textos analisados apontam para a necessidade da academia rever as políticas educacionais relacionadas à leitura e à produção escrita dos seus acadêmicos, pois se essas produções não correspondem ao esperado, acredita-se que seja necessária uma análise aprofundada desse quadro. ABSTRACT: This study discusses those related to the process of acquiring academic exercises in Portuguese by indigenous students of the Guarani and Terena ethnic groups who belong to the Francisco Horta Barbosa Indigenous Reserve in Dourados/MS. By accessing the academic educational system, these students are faced with criticisms that their writing does not meet the standard expectation of acceptable language in the university environment. This causes these students to increase the statistics of the so-called 'underrepresented'. To support this discussion, we use theorists such as Street (1984, 2000), which contrasts two models of literacy. The first model, Autonomous Model focuses on political-ideological purposes proper of a Western world perspective, whose education is based on neoliberalism. The second model, said Ideological Model, is delineated on the perspective of the insertion of the sociocultural context of its practitioners. This study investigates the practice of literacy as an indigenous language competence and writing skills in Portuguese. The corpus of the study is the writing of two texts of indigenous students, called indigenous narratives, in view of their different literacy events/practices. The two texts analyzed point to the need for the academy to review educational policies related to reading and written production of its academics, because if these productions do not correspond to what is expected, it is believed that an in-depth analysis of this framework is necessary.

Arginase 1 deficiency presenting as complicated hereditary spastic paraplegia

INTRODUCTION: Argininemia or arginase deficiency is a metabolic disorder caused by pathogenic variants in ARG1 and consists of a variable association of progressive spastic paraplegia, intellectual disability, and seizures. Hereditary spastic paraplegia (HSP) is a group of inherited diseases whose main feature is a progressive gait disorder characterized by lower limb spasticity. This study presents 7 patients with arginase 1 deficiency from 6 different families, all with an initial diagnosis of complicated HSP. METHODS: We evaluated the clinical data of 7 patients belonging to six independent families who were diagnosed with hyperargininemia in a neurogenetics outpatient clinic. RESULTS: All patients had lower limb spasticity and six had global developmental delay. Five individuals had intellectual disability and two had epilepsy. Psychiatric abnormalities were seen in two patients. In two participants of this study, MRI disclosed thinning of the corpus callosum. Molecular diagnosis was made by whole exome sequencing. All variants were present in homozygosis; we identified two novel missense variants, one novel frameshift variant, and one previously published missense variant. DISCUSSION: Clinical diagnosis of early onset complicated hereditary spastic paraplegia was made in all patients. Two patients were initially suspected of having SPG11 due to thinning of the corpus callosum. As argininemia may present with a highly penetrant phenotype of spastic paraplegia associated with additional symptoms, this disease may represent a specific entity amongst the complicated HSPs

Diagnóstico diferencial de linfonodomegalia: doença de Kikuchi-Fujimoto concomitante à Sífilis

A doença de Kikuchi-Fujimoto, assim nomeada na década de 1970, é uma doença benigna rara que se manifesta por meio de linfadenopatia cervical e febre, sem etiologia totalmente esclarecida, com poucos relatos anuais. Acredita-se que fatores autoimunes e/ou agentes infecciosos estejam relacionados a sua fisiopatologia. No entanto, a relação causal nunca foi comprovada. Neste relato, expõe-se o caso de uma mulher jovem, sem ascendência asiática, apresentando quadro de linfadenopatia cervical com duração de 4 semanas associada a febre e citopenias. Durante a investigação interna, diagnosticou-se sífilis latente tardia e o tratamento adequado foi iniciado. Porém, a despeito da terapêutica, a febre e linfonodomegalia persistiram, optando-se, assim, por biópsia linfonodal, cujo resultado caracterizou linfadenite necrotizante e doença de Kikuchi-Fujimoto. Nenhum relato da doença concomitante à sífilis foi encontrado nas referências

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Produção de fotinos e gluínos nas extensões supersimétricas da eletrodinâmica quântica e da cromodinâmica quântica

Neste trabalho, realizamos um estudo sobre a produção de gluínos no LHC. Os gluínos são partículas de Majorana, e sua existência é predita pelos modelos supersimétricos de física de partículas, como o MSSM. Inicialmente, motivamos o estudo sobre supersimetria mostrando algumas soluções de problemas usando esta teoria e que não são possíveis de explicar a partir do Modelo Padrão de física de partículas. Trabalhamos também os conceitos fundamentais para a construção de extensões supersimétricas, como a definição de superespaço e supercampos. Com a introdução do conceito de supercampos, mostramos que o espectro de partículas do Modelo Padrão é duplicado, com a inclusão dos parceiros supersimétricos aos campos usuais. Demonstramos como são construídos dois importantes exemplos de teorias supersimétricas, a Eletrodinâmica Quântica Supersimétrica (super QED ou SQED), e a Cromodinâmica Quântica Supersimétrica (super QCD ou SQCD). Para isso, construímos as lagrangeanas destas teorias e obtivemos as regras de Feynman, em ordem dominante (LO), para os principais vértices da SQED e SQCD. Mostramos também como são introduzidos os superparceiros das partículas usuais da QED, ou seja, o selétron (superparceiro do elétron) e o fotino (superparceiro do fóton), e da QCD, ou seja, o squark (superparceiro do quark) e o gluíno (superparceiro do glúon). Como o fotino e o gluínos são partículas de Majorana, mostramos um conjunto de regras que tratam de partículas de Majorana e de Dirac de forma simples e análoga. Com estas regras, vimos como é possível fazer os cálculos para espalhamentos do tipo e−e+ → ˜γ˜γ e para os canais básicos da produção de gluínos a partir de colisões próton-próton (pp). Na última parte do trabalho, analisamos a produção de gluínos em colisões pp, bem como em colisões próton-núcleo (pA) e núcleo-núcleo (AA) no LHC, onde obtivemos que, em colisões nucleares, a produção de gluínos pode ser enaltecida ou suprimida dependendo da magnitude dos efeitos nucleares, e do cenário para quebra de SUSY.In this work we perform a study about gluino production at the LHC. The gluinos are Majorana particles and their existence is predicted by supersymmetric models of particle physics, such as the MSSM. Initially, we motivate the study about supersymmetry by showing how it solves some problems that could not be explained by the Standard Model of particle physics. We also work the fundamental concepts such as the definition of superspace and superfields in order to construct supersymmetric extensions. With the introduction of superfields, we show that the particle spectrum of the Standard Model is duplicated, with the inclusion of the supersymmetric partners of usual fields. We demonstrate how to build two important examples of supersymmetric theories, namely the Supersymmetric Quantum Electrodynamics (super QED or SQED), and the Supersymmetric Quantum Chromodynamics (super QCD or SQCD). To do this, we build the lagrangians of these theories and obtain the Feynman rules, in leading order (LO), of the main vertices of SQED and SQCD. We also show how to introduce the superpartners of the usual particles - in SQED, one has the seletron (eletron superpartner) and the photino (photon superpartner), and in SQCD, one has the squark (quark superpartner) and the gluino (gluon superpartner). Since the photino and the gluino are Majorana particles, we show a set of rules that deal with Majorana and Dirac particles in a simple and analogous way. By using these rules, we make a full calculation of the processes e−e+ → ˜γ˜γ and of the basic channels of gluino production in proton-proton (pp) collisions. In the last part of this work, we analyse the gluino production in proton-proton, protonnucleus (pA) and nucleus-nucleus (AA) collisions at the LHC, and show that in the collisions involving nuclei, the production of gluinos might be enhanced or suppressed depending on the magnitude of the nuclear effects and on the scenarios for the SUSY breaking mechanism
