Padrões normativos de gênero em livros infanto-juvenis sobre educação sexual

The concept of gender is relational and refers to the the overcoming of the biological determinism, it has historical and cultural roots going beyond the anatomical differences between men and women. This documental research investigated patterns of sexuality and gender in sexual education books for children and teenagers. Ten books were analyzed, selected in bookstores websites. The content of the books and their illustrations show: 1) stereotypical and naturalized view of femininity and masculinity, 2) patterns of traditional and patriarchal families, 3) romanticized concept of marriage and reproduction, 4) stereotypes of beauty and "normal" body. It is concluded that sexual education books for children and teenagers reproduce normative standards that can stimulate a sexist education and should not be used in works of sexual education without critical reflection.

A step to the gigantic genome of the desert locust: chromosome sizes and repeated DNAs

The desert locust (Schistocerca gregaria) has been used as material for numerous cytogenetic studies. Its genome size is estimated to be 8.55 Gb of DNA comprised in 11 autosomes and the X chromosome. Its X0/XX sex chromosome determinism therefore results in females having 24 chromosomes whereas males have 23. Surprisingly, little is known about the DNA content of this locust's huge chromosomes. Here, we use the Feulgen Image Analysis Densitometry and C-banding techniques to respectively estimate the DNA quantity and heterochromatin content of each chromosome. We also identify three satellite DNAs using both restriction endonucleases and next-generation sequencing. We then use fluorescent in situ hybridization to determine the chromosomal location of these satellite DNAs as well as that of six tandem repeat DNA gene families. The combination of the results obtained in this work allows distinguishing between the different chromosomes not only by size, but also by the kind of repetitive DNAs that they contain. The recent publication of the draft genome of the migratory locust (Locusta migratoria), the largest animal genome hitherto sequenced, invites for sequencing even larger genomes. S. gregaria is a pest that causes high economic losses. It is thus among the primary candidates for genome sequencing. But this species genome is about 50 % larger than that of L. migratoria, and although next-generation sequencing currently allows sequencing large genomes, sequencing it would mean a greater challenge. The chromosome sizes and markers provided here should not only help planning the sequencing project and guide the assembly but would also facilitate assigning assembled linkage groups to actual chromosomes.

Epigenetic and genetic approach to the transmissibility of dental characteristics in twins: report of two cases

Transmissibility of dental and jaw characteristics is strongly influenced by environmental factors during the years of extra uterine life when odontogenesis occurs. Through biochemical factors, such as enzymes, proteins, hormones and other mediators, genes are activated or silenced to suit the cell or organism to its environment. These changes are not transmitted to our descendants, because of that, these factors are called epigenetic. Among the most cited epigenetic factors are food, pollution, drugs and exercise. The objective of this study was to assess the transmissibility of dental characteristics in two pairs of twins. In one case, 13-year-old boys had the same basic dental and jaw characteristics with prolonged retention of the second upper deciduous molars and the presence of permanent successors. In the other case, 14-year-old boys had prolonged retention of lower deciduous second molars and absence of permanent successors, but only one of them had the germs of third lower molars. The phenotypic difference in the dentition of twins from clinical case 2 could be due to epigenetic factors, showing the absence of genetic determinism in the transmissibility of dental characteristics.

Mondrian e o percurso de uma poética

This dissertation titled Mondrian “The Way of Poetry” was developed during the period of the first half of 1991 to the first half of 1993 in the Graduate course “ Projeto, Arte e Sociedade “, in the Visual Poetics area of concentration.This paper proposed the approach of determinism versus creative activity in the course of the work of Mondrian which conventionalized the term “The Way of Poetry.”

O conhecimento biológico nos documentos curriculares nacionais do ensino médio: uma análise histórico-filosófica a partir dos estatutos da biologia

We analyzed the National Curriculum for Secondary Schools with respect to the ontological, epistemological, historical, social and conceptual biology. This study aims to bring information and thinking about the inclusion of history and philosophy of biology for secondary education and for teacher training. We performed an analysis of PCNEM, PCNEM+ and Curriculum Guidelines as a whole from established categories. The results indicate a predominance of the ontological view of mechanistic biology. Epistemologically, although acknowledged, the question of scientific method is rarely discussed. The historical approach and social scientific activity and scientific knowledge are recognized by the documents, but an instrumental view prevails. The conceptual aspects are comprehensive and take into account the theories of structural biology. A philosophical discussion on the biology is missing in the parameters, indicating the need for the inclusion of issues related to ideas of determinism, chance and teleology.
