Xilitol: um edulcorante diversificado e benéfico para a saúde humana

This work aims to present through a literature review, the main features and employability of the natural sweetener xylitol. This sweetener has low calorie, can be used by people with diabetes and is an excellent substitute for sucrose and other sweeteners. Xylitol can be separated from many fruits and vegetables through the reduction of xylose, which can occur by chemical or biotechnological synthesis. In addition to their use in the food industry, xylitol also has great value beneficial to human health by acting as anticariogenic, preventing and treating diseases such as acute otitis media and hemolytic anemia, as well as being growth inhibitor of various bacteria

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.

Protagonismo politico e social na velhice: cenários, potencias e problemáticas

The active presence of the old ones in the society brings up discussions about the political and social participation in the advanced ages of the life. The senior citizen, like an actor of great relevance in the present time, shows their potential as scriptwriter and protagonist of their own history. However, many spaces constituted vertically, turned for this aim become artificial, abolishing, many times, the spontaneity and potential of these actors. Anyway, the important thing is to open spaces for the different expressions of social participation and that they find their legitimacy and place in the set of the protagonism that attaches life and sense to the world.
