The experiments with the suspension of plasma membranes of myometrium cells, treated with 0.1% digitonin solution, were used to study kinetic regularities of the inhibitory effect of tetra-N-phenylsulfonyl trifluoroacetamidine-thiacalixarene (С-1087) on the activity of Са2+,Mg2+-ATPase. The studies demonstrated the impact of C-1087 on the cumulative effect and the maximal velocity of ATP hydrolysis. No effect of С-1087 on the affinity between Са2+,Mg2+-ATPase, and АТР, affinity and cumulative effect of Ca ions and activation coefficient for Mg ions was revealed. A considerable decrease in the maximal velocity of ATP hydrolysis evidenced a complete non-competitive mechanism of inhibiting Са2+,Mg2+-АТРase activity with thiacalix[4]arene С-1087. Computer simulation demonstrated that thiacalix[4]arene С-1087 inhibiting effect on Са2+,Mg2+-ATPase may be conditioned by the cumulative effect of four spatially oriented N-sulfonylamidine groups on the upper rim of its macrocyclic platform.

Diethyl phthalate (DEF) is a synthetic chemical widely used as plasticizer and additive in personal care and pharmaceutical products. Low-dose exposure to this xenobiotic over a long period contributes to its intake into the human body in a high doses. To date, studies of DEF influence on free radical processes in liver cells, in which it is not only metabolized but can also have a prooxidant effect, remain limited. The aim of our research was to determine ROS formation, the intensity of oxidative modification of proteins (OMP) and proteolytic activity in the mitochondrial fraction of liver tissue of rats exposed to diethyl phtalate. The experimental white outbred rats were divided into three groups: I – intact animals (control), II and III – rats administered DEF orally for three weeks at a doses that reflect the dose levels received by humans, namely 2.5 and 5.4 mg/kg b.w. respectively. The animals were euthanized on the 14th and 21st day after xenobiotic administration. The mitochondrial fraction from the rat liver was isolated and the level of superoxide and hydroxyl radicals, protein carbonyl derivatives, SH-groups and Schiff bases was determined. Proteolytic activity was assessed in the test of hemoglobin cleavage. It was shown that administration of DEF in a dose of 2.5 mg/kg initiated ROS generation and OMP intensification in the rat liver mitochondria only with prolonged administration for 21 days, whereas its administration in a dose of 5.4 mg/kg led to intensification of these processes already on day 14th followed by further amplification on day 21st. The activity of proteolytic enzymes in the mitochondrial fraction was found to be depended on the degree of DEF–induced OMP and was increased with minor OMP intensification but decreased with significant intensification of proteins free radical oxidation. Keywords: carbonyl derivatives, diethyl phthalate, liver, mitochondrial fraction, proteolytic enzymes, ROS, SH-groups

We have previously shown that Bacillus sp. IMV B-7883 exhibits both elastase and fibrinogenolytic activity. One of the approaches to enhance enzymatic activity is the use of coordination compounds capable to affect enzyme’s activity or synthesis. The purpose of this work was to study the effect of mixed-ligand complexes of Ge(IV) – Co(II) (Ni(II), Cu(II)) with 1-hydroxyethane-1,1-diphosphonic acid аnd 2,2′-bipyridine on the activity of elastase and fibrinogenase purified from Bacillus sp. IMV B-7883. Previously synthesized and characterized mixed-ligand complexes and enzymes purified from the supernatant of the bacterial culture liquid were used in the study. Elastase activity was determined colorimetrically with the use of Congo red, fibrinogenase activity was estimated by fibrinogen hydrolysis measured by absorption at 275 nm. It was shown that complexes 1 (C132H164Co4Ge6N24O68P12) and 2 (C132H148Ge6N24Ni4O60P12) inhibited activity of Bacillus sp. IMV B-7883 elastase by 54 and 71% respectively, while complex 3 (C92H128Cu4Ge6N16O63P12) enhanced it by 30%. Stimulating effect of all three complexes on fibrinogenase activity was revealed. Thus, complex 1 and 2 activated the enzyme by more than 50% and complex 1 – by 19%. The data obtained indicate a complex mechanism of the studied complexes influence on enzymatic activity depending on both their composition and structure.

Published: February 2024

Due to the relative independence from the operational parameters, the linear retention indices (LRIs) are useful tool in gas chromatography-mass spectrometry (GC-MS) qualitative analysis. The aim of the current study was to develop a multiple linear regression (MLR) model for the prediction of LRIs as a function of selected molecular descriptors. Liquid injection GC-MS was used for the analysis of Essential oils (Rose, Lavender and Peppermint) separating the ingredients by a semi-standard non-polar stationary phase. As a result, a sum of 103 compounds were identified and their experimental LRIs were derived relying on reference measurements of a standard mixture of n-alkanes (from C8 to C20). As a next step, a set of molecular descriptors was generated for the distinguished chemical structures. Further, a stepwise MLR was applied for the selection of the significant descriptors (variables) which can be used to predict the LRIs. From an exploit set of over 2000 molecular descriptors, it was found that only 16 can be regarded as significant and independent variables. At this point split validation was applied: the identified compounds were randomly divided into training (85%) and validation (15%) sets. The training set (87 compounds) was used to derive two MLR models by applying i) the ‘enter’ algorithm (R2 = 0.9960, RMSЕ = 17) and ii) the ‘stepwise’ one (R2 = 0.9958, RMSЕ = 17). The predictive power was assessed by the validation set (16 compounds) as follows i) q2F1 = 0.9896, RMSE = 25 and ii) q2F1 = 0.9886, RMSE = 26, respectively. The adequateness of both regression approaches was further evaluated. Newly developed headspace-solid phase microextraction (HS-SPME) procedures in combination with GC-MS were used for an alternative analysis of the studied Essential oils. Twelve additional compounds, not previously detected by the liquid sample introduction mode of analysis, were identified for which the values of the significant descriptors were within the working range of the developed MLRs. For the last compounds, the LRIs were calculated and the experimental data was used as an external set for assessment of the regression models. The predictive power for both regression approaches was assessed as follows: Enter RMSE = 41, q2F2 = 0.9503 and Stepwise RMSE = 40, q2F2 = 0.9521.

Published: February 2024

Corrosion under insulation (CUI) is very common and severely occurs in chemical/oil and gas industries, however, it is difficult to detect this corrosion by non-destructive testing (NDT) techniques. Carbon steel resistant sensors were used to determine CUI in this research. The output voltage values of the sensor were measured over time and from which the corrosion loss in sensor’s thickness was calculated. Carbon steel samples were exposed to the sensors under the same conditions for the same periods, and the corrosion loss of the samples was determined by weight loss. The results show that when the sensors were corroded within 10-20 % the corrosion loss of carbon steel samples is equivalent to that calculated from the output data of the sensors with a standard deviation of 6-24 %. These results demonstrate the high potential of resistance sensors in determining CUI and predicting damage of industrial components and pipes.

Published: February 2024

Collagen is a natural protein presenting in the animal and human’s body. It is in natural fibrous and could be found in the connective tissue and flesh of mammal, approximately 25-35 wt.% of total human protein. Collagen is abundant in fibrous tissues such as: bones, cartilage, tendons, blood vessels, ligaments, skin, cornea, aortic disc and intestines. Fish collagen is currently being studied as a new biological substitute for collagen from animals. It extracted from by-products (scales, skins, bones, etc.) by biochemical or biological methods is safe, has high adsorption, high compatible. The factors influencing on the extraction process include temperature, time, concentration of ingredients, etc. The fish collagen is usually collagen type I with a fibril structure. Each unit of collagen is tropocollagen consisting of three polypeptide chains twisted together. Depending on the source of ingredients, the composition of aminoacids, denaturation temperature, the sequence of aminoacids, structure, morphology, molecular weight, extraction yield, etc. of obtained collagens are different. This paper reviews the extraction and characterization of fish collagen from products after fish processing by chemical or biochemical methods. The applications of fish collagen in wound healing and drug delivery are also reviewed.

Changing pedagogy in rural secondary schools through the technology, pedagogy, content, and spaces (TPeCS) knowledge framework
Authors: Mthethwa Lindiwe C.
Published: February 2024

The coronavirus disease (COVID-19) pandemic exposed insecurities and inequalities in schools. As such, there has been changing pedagogy in rural secondary schools in the uMkhanyakude district. Teachers adopted the technology, pedagogy, content, and spaces (TPeCS) knowledge framework, integrating planned behaviour. Teachers and learners engaged in discussion as a means of teaching and learning mathematics after school hours. This implicated cultural and sociological dimensions that were common among rural teachers and learners. Although the findings of this study could not be generalised, an all-encompassing framework for rural secondary school teachers and learners through online discussions is recommended. Novel technology-enhanced out-of-school teaching and learning activities were developed through progressive, participatory action-research. Furthermore, the findings support collaboration and a new contextualised theory called the technology, pedagogy, content, interaction, and spaces (TPeCIS) knowledge framework.

Published: February 2024

Este ensaio visual analisa o episódio da censura da obra “1 Bolsominion”, do artista André Parente, que motivou o cancelamento da exposição Desmonumento no Museu de Arte Contemporânea do Rio Grande do Sul, em julho de 2023. São apresentados os argumentos dos personagens envolvidos, assim como as características da obra em questão e de outras que compõem a exposição. O interesse do artista pela conjuntura sociopolítica do Brasil desde junho de 2013, passando pelos momentos críticos do impeachment da presidenta Dilma Rousseff e culminando na gestão de Bolsonaro, formam a paisagem crítica do conjunto de trabalhos de Desmonumento. Examino o gesto criativo de desfiguração de símbolos nacionais realizado por Parente como detonador de uma força socialmente transgressora e sagrada, com efeitos para a construção da memória da nação.
O Cais do Valongo como palco religioso: ritual, memória e patrimônio num palimpsesto urbano
Authors: Souty Jérôme
Published: February 2024

Desde a abertura ao público do sítio arqueológico do Valongo, em julho de 2012, numerosas performances artísticas e festivas, militantes, rituais e religiosas, acontecem no anfiteatro e na esplanada em torno do antigo cais. O artigo se interessa pela atuação das religiões de matrizes africanas nesse espaço, focalizando o ritual anual de lavagem do cais dos escravizados pelas Baianas. Ele mostra que as performances rituais ligadas ao candomblé de nação nagô-ketu (apesar de uma antiga e massiva presença bantu neste lugar) foram investidas de um papel central assim como de uma legitimidade singular no trabalho de resgate memorial, de afirmação de identidades e de reivindicação sociopolítica. Essas práticas populares, imateriais e efêmeras participam também da patrimonialização do Cais do Valongo.

Authors: Dupin Leonardo , Martins Marcio
Published: February 2024

Este é um ensaio visual que tem como tema a IV Romaria pela Ecologia Integral a Brumadinho, uma ação contramonumental que se faz presente anualmente na vida pública do município desde 25 janeiro de 2020, quando se completou o primeiro ano do rompimento do complexo de barragens da Vale S.A na mina Córrego do Feijão, que matou 272 pessoas. Ele foi realizado em 2023, sendo composto por 8 imagens que demonstram como o rito se constrói como contraponto ao design proposto pela mineradora, responsável pela devastação da paisagem, para reconstrução da memória. A romaria evidencia a capacidade das populações locais atingidas de responderem, a seu próprio modo, às práticas da empresa criminosa e do Estado na construção de uma “memória oficial”, chamando atenção para o caráter destrutivo dessas megaempresas e buscando a reparação pelos danos e violações de direitos sofridos pelas vítimas das tragédias.
Padrões de pedra, contos da memória e silêncio da história: o culto ao marco de fundação da cidade do Rio de Janeiro
Authors: Andrade Francisco Dias de
Published: February 2024

O artigo aborda a relação entre relíquias históricas e narrativas fundacionais como foi configurada pela atuação dos museus públicos e das políticas de proteção aos monumentos históricos desde o século XIX. O enfoque recai sobre artefatos e monumentos de pedra que representavam a gênese longínqua de identidades coletivas a despeito da ausência de qualquer suporte documental, valendo-se apenas ao seu valor de antiguidade. Para tanto, apoia-se nos conceitos de ilusão museal, memória pública e rituais de memória. Propõe, então, um estudo de caso sobre o marco da cidade do Rio de Janeiro (hoje sob a guarda dos frades capuchinhos do Santuário de São Sebastião, no bairro da Tijuca), procurando reconstituir a sua vida social e o seu papel no culto ao padroeiro da cidade ao longo do tempo.
Ansiedade e reciprocidade: a Igreja Universal do Reino de Deus além das fronteiras
Authors: Lehmann David
Published: February 2024

A mensagem da Igreja Universal do Reino de Deus (Iurd), organização transnacional centralizada, é sombria e nada otimista, com influência limitada, embora real, da teologia da prosperidade. Enfatiza as forças diabólicas e encoraja os seguidores a desconfiarem dos outros e até mesmo de suas próprias motivações ao orar, suplicar e doar. Nas performances rituais, os pastores alertam os seguidores para não esperarem nada em troca. O ritual é descrito como “disruptivo”. O texto compara a tratamento dado pela Igreja aos cultos de possessão no Brasil, Moçambique e África do Sul. A cura e o exorcismo são considerados no contexto das relações de reciprocidade, com exemplos de “psicoterapia popular” observados na televisão no Brasil. A pesquisa se desenvolveu em vários países.

Abstract: The message of the Universal Church of the Kingdom of God (UCKG), a centralized transnational organization, is gloomy and not at all optimistic, with limited, though real, influence from prosperity theology. It emphasizes diabolical forces and encourages followers to be suspicious of others and even their own motivations when praying, supplicating, and giving. In ritual performances, pastors warn followers not to expect anything in return. Rituals are described as "disruptive." The text compares the Church's treatment of possession cults in Brazil, Mozambique and South Africa. Healing and exorcism are considered in the context of relationships of reciprocity, with examples of "popular psychotherapy" observed on television in Brazil. The research was carried out in several countries.

Authors: SILVA CRISTÓVÃO TEIXEIRA RODRIGUES , BANDEIRA JOÃO ADOLFO RIBEIRO , MENEZES ANTONIO BASILIO NOVAES THOMAZ DE
Published: February 2024

ABSTRACT: The set of Human Rights is a direct response to the totalitarian practices of extermination of human beings, the result of a technical-instrumental rationality, during World War II (1939 - 1945). Thus, this article seeks to investigate whether education is an adequate strategy for the formation of a multidimensional Culture of Human Rights based on the intersubjective sharing of values, without using force/violence or political/economic superiority as elements as promoters of the commons. It begins with the presentation of some concepts and characteristics regarding education and Human Rights. Next, the multiplicity of foundations and dimensions of Human Rights Education HRE as outlined from the second half of the twentieth century, in international and national documents. Finally, the main characteristics of a technical-instrumental world-culture and the possibilities of social transformation are addressed, through human interaction mediated by communication. The article is developed in a dialectical approach, using the literature review as a technique, which subsidizes the discussion of concepts and the analysis of some legal documents. After the investigative path, it is concluded that HRE is a multidimensional strategy for promoting a Culture of Human Rights by reinforcing the common aspects of humanity, producing consensus around human dignity, respect, and inclusion, without resorting to the use of force, threat, or oppression.

ABSTRACT: This study aims to analyze the scientific evidence on ethnic-racial relations education in the scope of technical professional education at the secondary level. This is an exploratory and qualitative research, whose integrative literature review technique allowed the systematic selection of reports in six stages. Initially, the search of articles through SciELO, CAPES Journal, and Google Scholar from the terms race, ethnicity, race factor, racism, racial prejudice, racial discrimination, ethnic-racial relations, professional and technological education, and professional education, along with Boolean operators, resulted in 11,336 titles, and after screening, 11 articles were included. For discussion, the following categories were used: institutionalization of Law nº 10.639/2003 and curriculum; structural racism; quota law; nucleus of Afro-Brazilian and indigenous studies, research and extension; pedagogical experiences about ethnic-racial diversity; students' and teachers' perceptions of ethnic-racial diversity in the curriculum; and the role of teachers for the professional education of black women. It was found that there is a long way to go for the institutionalization of Laws 10,639/03 and 11,645/08 in the curricula and in the teaching-learning practices of vocational training, reinforced by the negative perceptions of students and teachers about ethnic-racial diversity in the curricula. of professional and technological education institutions, especially when it comes to integrated courses. However, the quota laws, the implementation of NEABI, and the different teaching experiences stood out as affirmative actions that promoted racial equality.

Published: February 2024

RESUMO: O presente estudo objetivou investigar como o gênero multimodal meme tem sido mobilizado em provas da área de Ciências da Natureza (Química, Física e Biologia), tendo como material de análise as provas de vestibulares tradicionais e seriados das universidades públicas estaduais e federais aplicadas nos últimos vinte anos (de 2001 a 2021), fazendo uso, para isso, da Taxonomia de Bloom Revisada. Trata-se de uma pesquisa quali-quantitativa, do tipo documental, realizada por meio de levantamento e análise dos dados. Os resultados mostram que apenas cinco memes estavam presentes nas provas analisadas e que três dos memes identificados apresentavam a dimensão do conhecimento efetivo/factual, enquanto os outros dois, por sua vez, manifestavam conhecimento conceitual. Já as dimensões dos processos cognitivos percebidas dizem respeito aos três primeiros níveis, sendo eles: lembrar (nível 1), entender (nível 2) e, por fim, aplicar (nível 3), mediante a problematização, de forma humorada. Em relação aos conteúdos abordados nos memes, quatro são da Química (ácidos e bases; características gerais do estado líquido; propriedades periódicas; ligações covalentes) e um da Biologia (citologia: organelas citoplasmáticas). Não foram encontrados memes voltados para a área da Física. O estudo relevou, também, um número incipiente de memes nos vestibulares das universidades analisadas, apontando, com isso, para a necessidade de uma maior promoção e investigação deste artefato da cultura digital

Published: February 2024

Resumo Quando uma estrutura soldada sofre impacto estrutural, a ductilidade do material é uma das características preponderantes. Contudo, com o crescente destaque e utilização dos aços de alta resistência e baixa liga (ARBL) nem sempre este fator é considerado na sua utilização. Isto pode resultar em instabilidades globais e/ou localizadas numa estrutura. Desta forma, o objetivo principal deste trabalho foi comparar o comportamento ao impacto estrutural de perfis I soldados, produzidos com ASTM A36, um aço estrutural “comum”, e EN10149-2 S700MC, aço ARBL, soldados em filete por processo de soldagem por arco elétrico com atmosfera de proteção gasosa MAG (GMAW) e utilizando metais de adição, AWS ER70S- 6 e AWS ER110S-G, que depositam metais de solda com grandes diferenças em resistência à tração e ductilidade. No desenvolvimento deste trabalho foram elaborados conjuntos soldados (CS) na forma de perfis I de chapas soldadas e mantendo-se as soldas com acabamento original. Os CS foram feitos em ambos materiais variando o metal de adição e condições de reforços. Entre os principais resultados, destaca-se o comportamento do material de alta resistência (EN10149-2 S700MC) quando submetido a carregamento dinâmico, apresentou fratura na mesa superior, com comprimentos significativamente maiores que os apresentados pelo aço ASTM A36, sob mesmas condições de soldagem e carregamento. Além disso, a presença de reforço vertical na estrutura acaba por transferir o carregamento para a mesa oposta do perfil, porém sem anular a condição de fratura no material de alta resistência.

RESUMO Ligas Al-Cu-Li têm apresentado vantagens em relação às ligas Al-Cu-Mg convencionais usadas na indústria aeroespacial devido as suas propriedades, como alta resistência à fadiga e baixa densidade. As propriedades mecânicas destas ligas dependem de sua microestrutura. Neste trabalho, a atividade eletroquímica associada a microestrutura e comportamento à corrosão da liga Al-Cu-Li 2198-T8 foi investigada por testes eletroquímicos e ensaios de imersão em soluções contendo íons cloreto (Cl–). Os resultados obtidos mostraram que o comportamento eletroquímico e a susceptibilidade a corrosão desta liga são fortemente influenciados pela fase T1(Al2CuLi), a qual é a principal responsável pelo endurecimento da mesma. Foi observado ainda que esta fase é eletroquimicamente mais ativa do que a matriz de alumínio e, que quando exposta ao meio corrosivo, resulta em corrosão localizada severa (CLS), devido ao ataque cristalográfico. Nestas regiões foi observada intensa acidificação, principalmente dentro dos pites, resultando na evolução de gás hidrogênio, o que foi confirmado pelos ensaios de visualização em gel. Os resultados obtidos por técnicas eletroquímicas globais e técnica de varredura do eletrodo vibratório (SVET) confirmaram as observações dos ensaios de imersão e de visualização em gel.

ABSTRACT: This study aims to establish a therapy strategy for canine leukopenia induced by canine parvovirus (CPV) infection through intravenous infusion of allogeneic bone marrow mesenchymal stem cells (BMMSCs) and to evaluate the therapeutic effect of BMMSCs on canine parvovirus. Forty healthy 2-month-old dogs were randomly divided into four groups including the BMMSC treatment group (A), conventional treatment group (B), CPV infection group (C), and a normal control group (D). Then the A, B, and C groups were orally infected with CPV (103.25 TCID50/mL) at 1mL/kg, and the D group received the same dose of saline. After the onset of infection, Group A received mesenchymal stem cells (MSCs) and rehydration as the treatment; Group B was treated with anti-inflammatory therapeutics and rehydration; and Group C and D were injected with the same dose of physiological saline. The level of leukocytes rebounded significantly after the treatment with BMMSCs and returned to reference numbers on Day 3 after treatment, which was significantly higher than that in the conventional treatment group. The concentrations of IL-2 and IFN-α were gradually increased during the treatment, and the BMMSC treatment group exhibited significantly higher IL-2 and IFN-α concentrations than the conventional treatment group on Days 3 and 4. The expression of the virus in the blood gradually decreased during the treatment, and the BMMSC treatment group displayed a faster decrease than the conventional treatment group. These results showed the advantages of BMMSC treatment over conventional treatment. This study provides a new BMMSC treatment strategy for canine leukopenia induced by CPV infection and reveals the mechanism by which BMMSC increases leukocytes after CPV infection.
Reparto de tareas domésticas en el confinamiento por covid-19 en Extremadura (España)
Authors: Tostado-Calvo Olga , Pérez-Franco Ismael
Published: February 2024

Resumen: Muchos estudios económicos y sociales han invisibilizado las tareas domésticas y de cuidados desarrolladas históricamente por las mujeres. Con su incorporación creciente al mercado de trabajo, los hombres no han asumido en proporción el trabajo reproductivo. A la llegada del covid-19 dio comienzo una crisis sanitaria, económica y social y el funcionamiento de todos los hogares se modificó. Este trabajo persigue comparar los usos del tiempo segregados por géneros de parejas heterosexuales con hijos de una región española antes y durante el confinamiento. También pretende conocer si el reparto de tareas se hizo de forma proporcional a la reducción de carga laboral. Aunque los hombres redujeron su jornada en mayor medida, disminuyeron su carga de casi todas las tareas, excepto la de ir a hacer la compra al supermercado, la única que permitía salir al espacio público durante el confinamiento.
Siento que todo lo hago mal. Malabarismos de las madres trabajadoras en pandemia

Published: February 2024

Resumen: El objetivo de este artículo es analizar las experiencias de madres trabajadoras en la organización del cuidado de sus hijos e hijas durante las semanas de confinamiento obligatorio provocado por la pandemia del covid-19, entre marzo y mayo de 2020. Se trata de una investigación cualitativa realizada en Zaragoza, España, con entrevistas semiestructuradas a 16 madres trabajadoras, españolas y extranjeras, con hijos e hijas menores de 12 años a cargo, y que vivían en pareja o solas. Los resultados muestran que la pandemia y el confinamiento provocaron desequilibrios en los hogares en cuanto la atención a la crianza infantil, debido principalmente al cierre de los servicios de atención a la infancia, la reconfiguración del trabajo asalariado y la ausencia de redes de apoyo. Esta situación les obligó a poner en marcha nuevos arreglos domésticos que supusieron una sobrecarga de trabajo para las madres.
Emoções e ativismo familiar em defesa dos autistas no Brasil na década de 1980
Authors: Lopes Bruna Alves
Published: February 2024

Resumo: No presente artigo, temos como proposta apresentar o papel das emoções no ativismo de mães e pais de autistas no Brasil durante a década de 1980. A partir da triangulação de fontes documentais distintas (autobiografias, livros acadêmicos do período e matérias publicadas em periódicos), mapeamos as emoções mais comuns expressas pelos familiares em suas narrativas sobre a experiência com seus filhos, com destaque para a infelicidade e o amor. Observamos que as emoções possibilitaram uma análise crítica da realidade, o estabelecimento de vínculos de solidariedade e a construção das primeiras medidas que possibilitaram o reconhecimento dos direitos dos autistas no Brasil.
Las huellas del silencio en tres novelas del conflicto armado colombiano
Authors: Zárate Mendivelso Gincy , Sánchez Rivera Sonia Liced
Published: February 2024

Resumen: Este artículo interpreta las relaciones entre los usos literarios del silencio y las formas de violencia que transitan por algunos personajes femeninos, dentro de las novelas Abraham entre bandidos, de Tomás González (2010), Muchacha al desaparecer, de Marta Renza (2009) y Candelaria, de Germán Castro Caicedo (2000). En esencia, este análisis intenta determinar la manera en que el silencio configura las representaciones sociales de las mujeres en las obras, al mismo tiempo que expone la forma en que éste se incorpora en los mecanismos de la violencia ejercidos hacía estos personajes. El estudio del silencio en la literatura abre un horizonte de sentidos que permite ampliar su dimensión simbólica e inferir lugares de enunciación, a través de la comprensión de sus dinámicas en las prácticas discursivas de las novelas que hacen parte del corpus.
De quem é esse corpo? A sexualidade de mulheres com Síndrome de Down
Authors: Faria Marina Dias de
Published: February 2024

Resumo: A sexualidade de mulheres com deficiência vem sendo tratada como tabu por mães e pessoas que trabalham de maneira muito próxima a essas pessoas. Na presente pesquisa, tive como objetivo analisar as narrativas de mães e profissionais sobre a sexualidade das mulheres com Síndrome de Down (SD). Para isso, foram realizadas entrevistas com mães de pessoas com SD e com profissionais que trabalham diretamente com tais indivíduos. Os resultados mostram que o silêncio é a norma. As participantes da pesquisa ficaram visivelmente incomodadas em falarem sobre o tema e, quando falaram, disseram que as mulheres com Síndrome de Down não são independentes no que diz respeito aos seus próprios corpos. Uma das consequências graves da negação ao direito básico pelos seus corpos é o alto número de violência sexual sofrida pelas mulheres com Síndrome de Down.
Activismo y discapacidad en Latinoamérica: luchas por el reconocimiento
Authors: Rebolledo-Sanhueza Jame Alejandra , Galaz-Valderrama Caterine
Published: February 2024

Resumen: Esta revisión busca comprender las experiencias, demandas y los efectos político-sociales de los movimientos de la discapacidad en Latinoamérica desde una perspectiva crítica feminista. Se realizó una revisión de 39 artículos científicos. El reconocimiento y la incidencia política son las principales demandas del movimiento, y la Convención sobre Derechos de Personas con Discapacidad alentó la reivindicación de derechos, aun cuando presenta limitaciones en su implementación. En conclusión, se denota que pocos estudios incluyen un análisis interseccional, no obstante, identifican las complejidades de las inequidades sociales presentes en Latinoamérica. Considerar una perspectiva interseccional permitiría comprender la discapacidad como problemática amplia, evitando categorías identitarias y evidenciando las posibles alianzas entre los colectivos para las luchas comunes y la transformación social.
Vulnerabilidade de gênero e raça e o olhar interseccional sobre os desastres
Authors: Gantus-Oliveira Talita
Published: February 2024

Resumo: O risco a desastres é resultado de um longo processo de vulnerabilização das comunidades expostas aos fenômenos hidrológicos e/ou geológicos. O contexto socioeconômico e as desigualdades de gênero e raça agravam esta condição, gerando impactos diferenciais em determinados grupos. Sendo este um cenário crônico no Brasil, faz-se necessário investigar a construção sócio-histórica e a condição das áreas de risco nas cidades com recorrência de eventos como movimentos de massa e inundações. Para tanto, busca-se aqui analisar as condições sociais e materiais de vulnerabilidade de mulheres residentes nas áreas de risco a escorregamentos em Santos, São Paulo. A partir de uma metodologia qualiquantitativa, com métodos estatísticos e de cartografia, as discussões trazem elementos para compreender como e por que as mulheres, principalmente as não brancas, são mais afetadas pelos desastres.

ABSTRACT Coating medicated fish feed with a polymer minimizes the chances of drug leaching into the water. Tambaqui (Colossoma macropomum) is an economically important Amazonian fish frequently parasitized by the acanthocephalan Neoechinorhynchus buttnerae. In this study, we compared the effect of ethylcellulose (EC 0.75%) coating of feed medicated with the antihelminthic albendazole (ABZ 10 mg kg bw-1) and uncoated feed on treatment efficacy and bioaccumulation of ABZ in naturally parasitized tambaqui during 35 days. Treatment efficacy was 34% and 66% in fish fed uncoated and coated feed, respectively, but did not vary significantly among treatments. Total ABZ residue reached concentrations from 122.0 to 151.7 ng g-1, and did not vary significantly among treatments. The biomagnification factor was low, ranging from 0.0003 to 0.0004. EC coating did not significantly affect the efficacy of ABZ treatment and did not interfere with ABZ bioaccumulation in the edible tissue of tambaqui.
