A VIOLÊNCIA CONTRA A MULHER E O MITO DO AMOR ROMÂNTICO

O presente trabalho busca apreender a relação entre o mito do amor romântico e a violência contra a mulher na contemporaneidade. Para isto, recorre à teoria marxista a qual afirma que a desigualdade entre homens e mulheres surge a partir do estabelecimento da propriedade privada e da exploração do homem pelo homem. É na organização da família monogâmica que se assegura a reprodução do modo de produção vigente, o capital e quando esta ordem é desobedecida, utiliza-se a violência como forma de manter a dominação entre os indivíduos. O mito do amor romântico se constitui como um instrumento que a ideologia dominante utiliza para manter as mulheres submissas. O amor neste aspecto se apresenta como mais um instrumento para continuar mantendo a mulher no íntimo do lar doméstico. Com a emergência burguesa e o mito do amor romântico, a mulher permanece submissa ao homem, mas agora não apenas pelo poder coercitivo patriarcal, que permanece, contudo, adicionado por formas subliminares de coerção. Dessa forma. as distinções entre os sexos podem ser alteradas se houver igualdade substancial das relações mútuas, isso exige a erradicação completa de suas bases, incluindo de forma primordial, a propriedade privada

The influence of dehydroepiandrosterone on effector functions of neutrophils

Dehydroepiandrosterone (DHEA) is a steroid hormone secreted by the adrenal glands, gonads and brain. It is a precursor to sex hormones and also is known to have immune modulatory activity. However, little is known about the relationship between DHEA and neutrophils and thus our study evaluates the influence of DHEA in the effector functions of neutrophils. Human neutrophils were treated in vitro with DHEA and further infected with Salmonella enterica serovar Typhimurium. The treatment of neutrophils with 0.01 μM of DHEA increased the phagocytosis of Salmonella independent of TLR4 as the treatment did not modulate the TLR4 expression. Additionally, DHEA caused a decrease in ROS (reactive oxygen species) production and did not influence the formation of the neutrophil extracellular trap (NET). Steroid treated neutrophils, infected or stimulated with LPS (lipopolysaccharide), showed reduced production of IL-8, compared to untreated cells. Also, the protein levels of p-NFκB were decreased in neutrophils treated with DHEA, and this reduction could explain the reduced levels of IL-8. These results led us to conclude that the steroid hormone DHEA has important modulatory functions in neutrophils

Data from: In situ filamentous communities from the Ediacaran (~563 Ma) of Brazil

Precambrian filamentous microfossils are common and diverse. Nevertheless, their taxonomic assignment can be difficult due to their overall simple shapes typically lacking in diagnostic features. Here, we report in situ communities of well-preserved, large filamentous impressions from the Ediacaran Itajaí Basin (ca. 563 Ma) of Brazil. The filaments are uniserial (unbranched) and can reach up to 200 µm in width and up to 44 mm in length. They occur as both densely packed or sparsely populated surfaces, and typically show a consistent orientation. Although simple in shape, their preferred orientation suggests they were tethered to the seafloor, and their overall flexibility (e.g. bent, folded, and twisted) supports a biological (rather than sedimentary) affinity. Biometric comparisons with modern filamentous groups further support their biological affinity, suggesting links with either large sulphide-oxidizing bacteria (SOB) or eukaryotes. Other morphological and palaeoecological characteristics further corroborates their similarities with modern large filamentous SOBs. Their widespread occurrence and association with complex Ediacaran macrobiota (e.g. frondose organisms, Palaeopascichnus) suggest that they likely played an important role in the ecological dynamics of these early benthic communities by providing firm substrates for metazoans to inhabit. It is further hypothesized that the dynamic redox condition in the latest Ediacaran, with the non-continuous rise in oxygen concentration and periods of hypoxia, may have created ideal conditions for sulphide-oxidizing bacteria to thrive
