Avaliação dos efeitos de aloe-emodin em células uroteliais imortalizadas e neoplásicas cultivadas in vitro

Aloe vera (Aloe barbadensis Miller), popularly known in Brazil as babosa, has a long history of use as medicinal plant for different therapeutic purposes. The components of the plant extract are present in various products of human use, mainly for nutritional and cosmetics purposes. However, some studies suggest that this extract might also have carcinogenic activity. The aloe vera extract is a complex mixture of bioactive compounds. The study of isolated compounds may contribute to elucidate contradictory results about the effects related to the consumption of the plant, as well as their mechanisms of action. One of the most important compound from Aloe vera is aloe-emodin, which is a secondary metabolite generated in the intestinal tract. Putative antimicrobial and antitumor effects were previously attributed to aloe-emodin. Although the exposure of urothelial cells to aloe-emodin was already reported in the literature, only one study showed its effects on urothelial cells, suggesting that aloe-emodin inhibits the viability of T24 cancer cells due to apoptosis induction. Since there is no sufficient information about the effects of aloe-emodin on urothelial cells, and low efficiency in the treatment of bladder cancer currently, the present study aims to evaluate the hypothesis that the treatment with aloe-emodin could impact the behavior of other urothelial cell lines in vitro. Therefore, the in vitro IC50 exposure of aloe-emodin to human immortalized neoplastic urothelial cells will be determinated in order to verify possible differences in the behavior of urothelial cells in vitro treated with aloe-emodin in comparison with untreated cells. Furthermore, differences between cell lines will be also evaluated

Sobre O tronco, romance de Bernardo Élis

The conception of O tronco was influenced by Hegel´s ideas. The genesis of this novel is in Bernardo Élis’ purpose of writing a monograph on land ownership conflicts in Goiás, later transformed into a new project, the novel O tronco. The same ideological position of the author gives the argumentative direction of the novel; his ideological background determines the choice of the theme, associated with images expanded by the procedures of argumentation that permeate the literary discourse. Thus, in face of the undeniable aesthetic value of Élis´work, we analyzed O tronco, specifically the argumentation that guides the literary narrative, enhanced by the artistic treatment of violence, its theme, as the result of the struggle for power. The novel was published in 1956; the author, heir to the literary regionalism of the 30s, through an artistic and calculated combination of the story of a local government and literature, accuses, judges the exacerbated domination of a particular social group in a region in Goiás.

Efeito citotóxico de agentes clareadores a base de peróxido de hidrogênio a 20% e 38% sobre células odontoblastóides

The aim of this in vitro study was to evaluate the trans-enamel and transdentinal cytotoxic effects of two in-office tooth bleaching techniques that employ bleaching gels containing 20% and 38% of H2 O2 on cultured odontoblast-like cell line (MDPC-23). Sixty enamel/dentin discs were obtained from bovine central incisors and placed individually in artificial pulp chambers. Six groups were formed according to the following enamel treatments: G1- 20% H2 O2 (1 application); G2- 20% H2 O2 (2 applications); G3- 38% H2 O2 (1 application); G4- 38% H2 O2 (2 applications); G5- 38% H2 O2 (3 applications); and G6- control (no treatment). In G1 and G2, the bleaching gel was left in contact with the enamel surface for 45 min in each application. However, in G3, G4, and G5 the bleaching gel was applied for only 10 min per application. After the last application, the extracts were collected and applied on previously cultured cells (30.000 cells/cm2 ) for 24 h. Cell metabolism was evaluated by the MTT assay and cell morphology was analysed by scanning electron microscopy. Cell metabolism decreased by 96.29%; 96.11%; 96.42%; 95.62%; and 97.18% in G1, G2, G3, G4, and G5, respectively. All treated groups differed significantly from non-treated control group (G6) (p < 0.05). However, the difference in cell metabolism among treated groups was not significant statistically. In addition, significant morphological cell alterations were observed in all treated groups. Under the tested experimental conditions, the extracts collected after both tooth bleaching techniques evaluated in this study caused severe toxic effects on cultured odontoblast-like cell MDPC-23.
