Algumas reflexões sobre a condição da mulher brasileira da colônia às primeiras décadas do século XX

This article, about reflections on the condition of Brazilian women from the Colony to the first decades of the twentieth century, reveals the historical position of them and the attitudes and behaviors related to gender and sexuality. Subdued, it was treated as a sexual object, arousing all sorts of misogyny by men. Rebel, veiled or ostensibly, could serve their own desires. Throughout history, the Church and medical institutions which jointly accounted for, significantly, established the meaning and place of women. In Colony period, the woman is a ward from the Catholic ideology, but from the nineteenth century, after Independence, this power control arises to Medicine. The physician submits the religious discourse, naturalizing the status of women as one that breeds, namely the insertion of the medical issues of family scientifically legitimate colonial patriarchy. This is accentuated in the early twentieth century, when medicine consolidated setting standards and rules for marriage, to motherhood and family life. We note how the feminine universe was (and it is nowadays) ambivalent, with "one foot" in virtue and another in sin, with a tendency to contain and another to trespass. On the one hand we have the home and motherhood, validated in marriage, in which the woman is cared for and dependent on her husband. Reflecting on the motherhood of Virgin Mary, comes to the sacred dimension of the idealized woman saint by the Church. At the same time, however, feels the need for freedom, identity and independence, needing to give a voice to the desire to have their sexuality and all that it is due in full. The manifestation of the desire and the call for sexual satisfaction, and put in permanent conflict personal, psychological and social split between moral entrenched across generations and cultural transformations resulting from decades of the 20th Century.

Tegumentary epithelial glands in the abdomen of virgin and physogastric queens of the stingless bee Scaptotrigona postica Latreille (Meliponini: Trigonina)

Nas operárias das abelhas eussociais, regiões do epitélio tegumentar do abdome podem hipertrofiar-se e tornarem-se glandulares, sendo responsáveis pela produção de cera usada na contrução dos alvéolos de cria. Nos meliponíneos, epitélio com essas características também foi observado nas rainhas, porém sua função ainda continua desconhecida. Teria esse epitélio função homóloga nas operárias? As rainhas, além da função reprodutiva, desempenhariam funções na colônia até então consideradas exclusivas das operárias? Para tentar colaborar no esclarecimento dessas questões realizou-se um estudo histológico e ultra-estrutural das glândulas epiteliais tegumentares do terceiro tergito em rainhas virgens e fisogástricas de Scaptotrigona postica Latreille. Os resultados morfológicos mostraram que o epitélio glandular existe e é facilmente discernível no terceiro tergito das rainhas, sendo muito mais desenvolvido nas fisogástricas do que nas virgens. A ultra-estrutura mostrou que há diferenças no tipo de organização do retículo endoplasmático liso entre as rainhas, o que, juntamente com os resultados da histologia e morfometria, indicam poder haver diferenças funcionais desse epitélio entre elas. Como já observado na literatura, nas rainhas virgens tal epitélio pode estar envolvido na produção de cera e confecção de alvéolos de cria, porém sua função nas rainhas fisogástricas é totalmente desconhecida. A hipótese lançada no presente estudo é de que esse epitélio pode estar envolvido na produção de feromônios que irão atuar nas interações sociais da rainha poedeira.

Morphology, ultramorpholgy and morphometry of the fat body of virgin females and queens of the ants Pachycondyla striata (Hymenoptera : Formicidae)

The fat body cells of virgin females and queens of Pachycondyla striata ants belonging to the subfamily Ponerinae are illustrated from morphologic, ultramorphologic and morphometric viewpoints. Camera lucida drawing techniques were used, as well as scanning electronic microscopy (SEM). Measurements of trophocytes and oenocytes areas in the tissue were recorded. The results showed that in P. striata queens and virgin females the trophocytes are arranged in cord-like formations in association with oenocytes. Trophocytes of both castes had round shapes, with rather vacuolized cytoplasm, whereas oenocytes, being smaller than trophocytes, had more homogeneous cytoplasm. It was also observed that both trophocytes and oenocytes of virgin females were larger than those found in the same queen cellular types.

Soil humus characteristics in virgin and cleared areas of the paraná river basin in Brazil

A study of the characteristics and distribution of the soil humus fractions in representative ecosystems of central Brazil was carried out with special emphasis on the comparison between the soils under virgin vegetation-Cerrado-and those subjected to cultivation. In spite of the contrasted vegetation and cultural practices in the sites studied, the soil humus showed analogous characteristics: there was a negligible amount of plant residues, the humic and fulvic acids amounted to approximately 70% of the total organic carbon, and about 40% of these humic substances were in extremely stable association with the soil mineral fraction, the HCl-HF treatment being required for their extraction. The stability of such organo-mineral complexes increased slightly in the cultured sites. The study of the humic acid fraction showed increased oxidation and aromaticity in most of the cultivated sites: the lowest values for the IR alkyl vibrations and H/C atomic ratios and the highest ones for the optical density at 465 nm were observed in sites transformed into orchards, whereas the above changes were small in those used as pasture. The 14C NMR spectra confirmed that the proportion of polyalkyl structures decreased in the humic acids of soils subjected to cultivation, as opposed to that of carboxyl groups. In spite of the high stability inferred for the organic matter throughout the wide area examined, the samples from the original Cerrado as well as from those transformed into pastures showed, in laboratory conditions, higher mineralization rates than those from the sites subjected to cultivation. This is partly attributed to the decreased proportions of extractable humic substances in the latter. © 1992.

Fine needle aspiration biopsy of gastrointestinal stromal tumor presenting as an umbilical mass (Sister Mary Joseph's nodule)

The Sister Mary Joseph (SMJ) nodule is a clinical sign of metastatic cancer involving the umbilicus. The vast majority of these instances represent adenocarcinomas arising from ovarian or colorectal primaries. We present a patient who presented with ascites and the SMJ lesion that turned out to be a metastatic gastrointestinal stromal tumor after fine needle aspiration biopsy was performed. The lesion was subsequently histologically confirmed. Gastrointestinal stroma tumor involving the umbilicus is exceedingly uncommon and only rarely presents in this fashion. The cytomorphological features, differential diagnosis, and comparison with the tissue specimen are made. © 2006 Elsevier Inc. All rights reserved.

Effects of treatment of the fat body trophocytes of Melipona quadrifasciata anthidioides nurse workers and virgin queens in culture by juvenile hormone III and ecdysterone (20-HE)

The fat body (FB) consists of two types of cells: throphocytes and oenocytes. Throphocytes are related to intermediary metabolism storing lipids, carbohydrates, and proteins while oenocytes play role in the lipids and lipoproteins production. The vitellogenin is the precursor of egg yolk (vitelline) and is synthesized on FB. The aim of this work was to analyze the effects of hormones acting in bee reproduction, as juvenile hormone (JH) and ecdisteroids (20 HE) on FB cells, where vitellogenin is synthesized. For the study were chose nurse workers that in Melipona quadrifasciata anthidioides present activated ovaries and produce eggs, and virgin queens whose ovaries are not yet activated, presenting only previtellogenic follicles. FB trophocytes from these classes of bees were cultivated in media containing different amounts of JH and 20-HE. The effects on trophocytes cytoplasm reserves of lipids, proteins, and activity of acid phosphatase were compared by observing preparations from cultured FB, treated and control, by transmission electron microscopy (TEM). The results showed that the hormones effects are related to the bee's caste and functional ovary stage. The role of acid phosphatase on mobilization of the trophocyte reserves was also determined. © 2012 Wiley Periodicals, Inc.
