Enzimas de biotransformação em tilápia (Oreochromis niloticus) exposta ao hormônio natural 17b-estradiol

Among the sexual hormones the estrogens are receiving major attention due to their biological activity. Such biological response is atributed to the best conformation recognized by their receptors, resulting in maximum responses. The estrogens are also considered responsible for most of disruptor´s effects caused by their presence in aquatic ecosystems. The 17β-estradiol hormone is produced by vertebrates during the reproductive phase of their lives and its presence has been detected in superficial waters. The objective of this study was to evaluate the cause-effect of tilapia exposition to the hormone 17β-estradiol through the analysis of biotransformation enzymes in liver and gills, complemented with the quantification of 17β-estradiol and estrone in water samples collected from fish ponds integrated to swine production. The present study was conducted under laboratory conditions, in a randomized experimental design with three levels of 17β-estradiol (E2) (0, 5, 15 µg L-1), with three replicates. After 7 days of exposure time, liver and gills were extracted to analyze three isoforms of cytochrome P450: EROD, BROD, PROD and the activity of Glutathione S-Transferase (GST). The results showed that the EROD activity (CYP1A), normally induced by the metabolism of aromatic compounds, did not present statistical differences among the treatments exposed to E2, what means that the hormone did not induce isoform 1A in fish under these particular experimental conditions. PROD activity was significantly altered in both concentrations, by means of 5 and 15 µg L-1, when compared to control. This result can indicate an important role of PROD on the metabolism of E2 present in water. Regarding to the BROD activity, it could be observed differences statistically significant between control and both groups of treatments. Two or more CYP isoforms can contribute to the metabolism of the same compound, what makes BROD a candidate as a next bioindicator of the exposure to E2 in aquatic ecosystems. Analysis of variance could confirm the effect of E2 statistically significant on the GST activity in liver tissues with >90% of significance (Prob>F = 0.0753). Furthermore, it was possible to observe that the values of GSTs activities in liver and gills in both, control and treatments, follow a tendency, that means, enzymatic activity in gills increase as the increasing of the activity in the liver tissues. In this study, the 17β–estradiol was found in measurable concentrations in three sampled points, and these values were similar to the findings of other authors at different locations in Brazil. In addition, those values are much higher than the minimum concentration that presented observable effects (10 ng L-1).

Itens lexicais tabus: usá-los ou não. Eis a questão .

The language in use in a society is product of a culture and reflects the way a community thinks. Therefore, the lexical units, through the meanings assigned by a social group, establish a specific look of the universe. We intend to demonstrate that for the denomination of the sexual organs of the human body it usual to avoid the official anatomical terminology – relegated to contexts of great formality – and to adopt other lexical items during informal situations. We intend, with this research, to demystify some prejudices related to the erotic-obscene lexicon, its use and its creation, besides stimulating reflections, in Portuguese and Italian.

O léxico tabu: usos e aspectos socioculturais

The language in use in a society is product of a culture and reflects the way a community thinks. Therefore, the lexical units, through the meanings assigned by a social group, establish a specific look of the universe. We intend to demonstrate that for the denomination of the sexual organs of the human body it usual to avoid the official anatomical terminology – relegated to the contexts of great formality – and to adopt other lexical items during informal situations. This paper reflects about some sociocultural aspects of the forbidden language, that encloses the erogene zones. Using as theory the studies of Lexicology and the obscene lexicon, we intend to verify this lexical typology based in our corpus, and stimulate reflections about the use and the substitution of the official terminology, showing that there are variations in relation to the age and gender of the speakers. We intend, with this research, to demystify some prejudices related to the erotic-obscene lexicon, its use and its creation and to stimulate reflections.

Oficinas sobre sexualidade com adolescentes: um estudo de caso

Adolescents are commonly seen in a “sexless” way so that when the first sexual expressions appear in our young people they are permeated by worry and fear. In this context, the school spread the vision of sex and sexuality, as hazardous due to risks of sexually transmitted diseases and unwanted pregnancy. Thus, seeking to encourage reflection on the part of adolescents with regard to sexual life, workshops were developed with 15 students in a seventh grade student at a state school in the city of Jaboticabal, São Paulo. The findings of this research indicate that adolescents have conceptions of sexuality marked by repression, including the maintenance of sex roles traditionally established. The implementation of interventions in the form of workshops revealed that the group has become an area that favors the reconstruction and rebuilding of meanings through the questions and judgment of values and attitudes socially imposed.

As Tecnologias de Informação e Comunicação TIC na formação de professores em educação sexual: o caso das E-Oficinas na I COES

This article aims to describe how ICT can contribute to the training of teachers on sex education through the lived experience with the implementation of Workshops, which occurred on I COES - I Conference online of sexual education. This Conference was organized by the University of Lisbon-PT, in partnership with UNESP, SP and SC-UDESC. I COES involved education professionals, who work directly in the school to discuss and exchange their experiences related to sexuality education and related fields, through an online space. The research on teacher formation, initial and continuing on sexuality, sex education, gender and sexual diversity, have demonstrated the need to promote and encourage teachers from all areas, to adopt an intentional and emancipatory, their role as sexual educators . Through web conferencing tool Cisco System, I COES was enable the interaction and questioning of ninety five teachers from various parts of Brazil and Portugal, providing opportunities for rich moments of dialogue and reflection on the issues already mentioned, referring to the brazilian and portuguese realities.

Sexualidade e infância: contribuições da educação sexual em face da erotização da criança em veículos midiáticos

This article proposes to show the contributions of the sex education in the school as a way to mitigate the effects of the media, which sometimes leads to early sexualisation of children. Bibliographical in nature, it points out some aspects of sexuality in childhood, and reveals the issues brought by the media, particularly for the formation of the child, when addressing sexual issues, highlighting the role of sex education for a more reflective thinking about this theme.

Escola e o diálogo sobre corporeidade e educação sexual

The purpose of this work and to provide education professionals regarding the way a reflection of how the body has been seen and treated at school. In view of embodiment and sexuality education body and movement performed by him has received a new treatment in our time, overcoming the dichotomy inherited from the mechanistic paradigm and structured by Newton and Descartes and predominant in recent centuries. We know that these changes are consequences of the emergence of AIDS and the advancement of the incidence of unwanted pregnancies among young people of school age. Therefore, this discussion reinforces the need for training of teachers in promoting discussions about sexuality and corporeality with broader focus, dialogues, be traced paths to address the biopsychosocial aspects from a sociohistorical context of gender equity, respect for sexual diversity, the reduction of prejudice and violence against the so-called “minorities” sex.

Hibridismo cultural: o imaginário europeu na construção da sexualidade feminina do primeiro século de colonização brasileira

The aim of this study is to investigate and analyze the conceptions of sexuality and female sexual behavior and conduct, formed from the merger of information and securities purchased under the eyes, rules and guidelines established relations with the Holy Office during his visit to Inquisitorial Brazil in the late sixteenth century. It is a survey of historical methodology in which we used as the exploratory research and literature. In the sixteenth century the Church increases the pressure to change the sexual mores that were free in the Middle Ages, a fact which influences the rules and regulations that are adopted by the Holy Office regarding the person's sex life. The first structure was based on Brazilian sexual alliance between Indians and settlers, which led to sugar, by the Portuguese, the customs of the land, which included sexual practices free since the Indians were out of Christian influence. Supported by the absence of white women, the settlers took them wives of the earth, usually more than one, creating conflict with the Jesuits who condemned Indian polygamy. In this context, in 1591, landed on Brazilian soil Heitor Furtado de Mendonca, and with it, the First Visitation of the Holy Office to investigate, arguing, exploring feelings and behaviors, to discover the true facts, finally, to demonstrate the errors Faith and punish them with the rigor of ecclesiastical law. His passing opens us to visualize traces of sexuality in the current "Tropic" a racist, misogynist world where black women and degraded land could be subject to the wishes of the white man, with whom he could mate at will. Alone and forgotten, women have not found the colony margin to denounce or to speak and were stigmatized by the look of travelers and writers have been through here.
