Reproductive and developmental toxicity study using Sprague-Dawley rats exposed under various calendars to the weedkiller Glyphosate and commercial formulations Glyphosate-based

Glyphosate-based herbicides (GBHs) are the most globally used herbicides raising the risk of environmental exposition. Carcinogenic effects are only one component of the multiple adverse health effects of Glyphosate and GBHs that have been reported. Questions related to hazards and corresponding risks identified in relation to endocrine disrupting effects are rising. The present study investigated the possible reproductive/developmental toxicity of GBHs administered to male and female Sprague-Dawley rats under various calendar of treatment. Assessments included maternal and reproductive outcome of F0 and F1 dams exposed to GBHs throughout pregnancy and lactation and developmental landmarks and sexual characteristics of offspring. The study was designed in two stages. In the first stage Glyphosate, or its commercial formulation Roundup Bioflow, was administered to rats at the dose of 1.75 mg/kg bw/day (Glyphosate US Acceptable Daily Intake) from the prenatal period until adulthood. In the second stage, multiple toxicological parameters were simultaneously assessed, including multigeneration reproductive/developmental toxicity of Glyphosate and two GBHs (Roundup Bioflow and Ranger Pro). Man-equivalent doses, beginning from 0.5 mg/kg bw/day (ADI Europe) up to 50 mg/kg bw/day (NOAEL Glyphosate), were administered to male and female rats, covering specific windows of biological susceptibility. The results of stage 1 and preliminary data from stage 2 experiments characterize GBHs as probable endocrine disruptors as suggested by: 1) androgen-like effects of Roundup Bioflow, including a significant increase of anogenital distances in both males and females, delay of first estrous and increased testosterone in females; 2) slight puberty onset anticipation in the high dose of Ranger Pro group, observed in the F1 generation treated from in utero life until adulthood; 3) a delayed balano-preputial separation achievement in the high dose of Ranger Pro-treated males exposed only during the peri-pubertal period, indicating a direct and specific effect of GBHs depending on the timing of exposure.

The Legacy of Lolita: A Literary Genre of Pedophilia?

This thesis analyzes four works of fiction that portray a pedophilic relationship in order to establish whether we can identify what might be called a genre of pedophilia in literature. In the last decade, books about the topic have been published with great success, so it would seem that there is a need to classify and define the genre of pedophilia. To answer the question I started with the novel Lolita (1955), by Vladimir Nabokov, which is the most famous work of literary fiction on the topic of pedophilia. In my analysis of this text, I tried to show how this novel has laid the ground plan, as it were, for the genre. I then analyzed three contemporary novels: All the Ugly and Wonderful Things (2016) by Bryn Greenwood, My Absolute Darling (2017) by Gabriel Tallent and My Dark Vanessa (2020) by Kate Elizabeth Russell, and compared them with Lolita to find the essential elements that constitute the genre of pedophilia. The analysis showed that there were many elements, mostly themes, which the contemporary novels had in common with Lolita, which helped classify the genre of pedophilia as both transgressive and romantic fiction. But while the three contemporary novels share many aspects with Lolita, they also bring into play themes such as female desire, and a resistance to seeing the female as only victim, with little agency. While the most important aspect is that the work of fiction must show the evolution, from the beginning to the end, of a sentimental relationship and sexual acts between an adult and a child, the contemporary novels of this genre take this basic trait – particularly All the Ugly and Wonderful Things -- in surprisingly transgressive directions of their own.

Machado de assis's epilepsy

Machado de Assis (1839-1908) is considered the most important Brazilian writer and a great universal literary figure. Little is know about his medical, personal and family history. He hid his «disease» as much as possible. Machado referred to «strange things» having happened to him in his childhood. He described seizures as «nervous phenomena», «absenses», «my illness». Laet observed a seizure and described it as: «... when Machado approached us and spoke to me in disconnected words. I looked at him in surprise and found his features altered. Knowing that from time to time he had nervous problems,... and only permitted Machado take the Laranjeiras Street car, when I saw that he was completely well». A photographically documented seizure is shown. Alencar wrote, «The preoccupation with health was frequent: either he was having the consequences of a fit or was foreboding one». It is clear that Machado presented localized symptomatic epilepsy with complex partial seizures secondarily generalized of unknown etiology. The seizures which began in infancy or childhood had remission in adolescence and then recurred in his thirties and became more frequent in his later years. His depression got markedly worse with age. In our opinion, the greatest consequence of Machado's epilepsy, was his psychological suffering due to the prejudice of the times. Despite this Machado showed all his genius, which is still actual and universal.

Adolescência através dos séculos

A sociedade contemporânea ocidental estendeu o período da adolescência, que não é mais encarada apenas como uma preparação para a vida adulta, mas passou a adquirir sentido em si mesma, como um estágio do ciclo vital. O presente artigo procura descrever como os adolescentes eram vistos e tratados, desde a antiguidade até os dias de hoje, a partir de textos literários ou filosóficos e estudos científicos. O material bibliográfico a respeito da adolescência caracteriza-se por três etapas distintas: a descrição dos padrões de comportamento, ajustamento pessoal e relacionamento; a resolução de problemas reais por meio do conhecimento científico; e o desenvolvimento positivo do indivíduo, considerando os adolescentes como o futuro da humanidade.

Flaubert e o crepúsculo do sujeito: uma análise do conto "Um coração simples"

A literatura francesa e mundial passaram por uma enorme transformação ao longo do século XIX. A primorosa escrita de Flaubert é, para além de sua importância estética, reveladora de um novo modo de se escrever, ler e representar o homem no mundo moderno. O cuidado na construção do texto, a utilização de imagens plásticas e figuras de linguagem, ao mesmo tempo em que o narrador torna-se invisível no emprego do discurso indireto livre são característicos da escrita flaubertiana. O autor apresenta-nos em "Um coração simples" um "retrato" de Félicité, mulher pobre do interior da França, modelo virtuoso de uma ética evanescente. Ao acompanhar, por meio do conto, os passos e desventuras de Felicité, sob as lentes deste novo narrador, buscamos evidenciar as condições que circundam o aparecimento de um olhar científico-objetivo para a subjetividade humana, logo transformada em objeto de uma nascente Psicologia.

Sublimação e pulsão de morte: a desfusão pulsional

Com o advento do segundo dualismo pulsional freudiano, surge uma série de mudanças no entendimento da sublimação. Essa passa a se apresentar como a causa por excelência da desfusão das pulsões, o que nos leva a um paradoxo: ao mesmo tempo em que a sublimação é a base da cultura, ela é também causa da destrutividade no seio dessa mesma cultura. A pulsão de morte resultante da desfusão das pulsões, por sua vez, teria consequências tanto em cada indivíduo quanto na cultura como um todo, tal como o que se observa em relação ao primado da imagem na sociedade contemporânea. Este artigo busca discutir alguns dos efeitos da pulsão de morte desfusionada, entendida como resultado da sublimação, principalmente no que tange à sublimação implicada na criação literária.

Pessoa e Pirandello: confluência de dramas

The present study aims to compare two modern authors - Luigi Pirandello and Fernando Pessoa - from different cultural environments - Italy / Brazil - pointing to a common theme: the various levels of the individual's expression. The arguments to support the proposed analysis are based on the shifting literary genres, specifically on the non-dramatic characters by Pirandello and on the drama in people by Pessoa.

Um modo de ler um livro-biblioteca: a reescritura perecquiana na composição de La vie mode d'emploi

This article presents and analyses some aspects of Georges Perec's composition as shown in his book Life: a user's manual (1978). Starting with the image of a ""book-library"", composed by some of Perec's literary 'models', and discussing the theory of intextertuality and rewriting, we propose to analyse some possible approximations between Perec and Flaubert, especially in the latter's Bouvard and Pecuchet (1881).

Montagem e colagem na obra de Walter Kempowski

Montage was one of the great innovations of avant-garde literature. As time went by, this technique lost some of its shock effect and became increasingly a method for structuring the text. After the avant-garde literature movement, collage started to be mentioned as a concept together with montage, many times as a complement, but the concepts are often blended into each other. In this article, there will be an attempt to delimit what is montage and what is collage through an exposition of some theories and the examination of the way they are applied in the work of a contemporary writer, the German Walter Kempowski.

Altazor, de Vicente Huidobro: o gesto político numa das epopeias de XX

This article aims at presenting a reading of Vicente Huidobro's poem Altazor (1931,) assuming the epic genre postulations and the conditions of its development in the first half of the twentieth century. Important works were produced in that period, setting in motion a deployment of the epic genre as refashioned by the avant-garde movements and contesting the metaphysical formulations that had considered it impossible as a discursive space in modern times. Altazor is situated in this movement as a self-conscience of issues of language and its objective capacities. The work deals with the possible modes of enunciation of a great poet, Altazor, who lacks his former serenity of old and looks for a language able to transcend his mother tongue, because he does not accept its origin. His political revolution is performed on language, the artifice through which history is told.
