Abstract
BACKGROUND Jaboticaba (Myrciaria trunciflora) belongs to the family Myrtaceae and is a fruit native to the Atlantic Forest of Brazil. The aim of this study was evaluate the activity of the extract of jaboticaba against different stresses in Caenorhabditis elegans. METHODS Initially, the toxicological profile of the extract was analyzed, evaluating survival, reproduction, and longevity. After the tests of resistance to oxidative stress, thermal and against ultraviolet radiation were carried out. In order to discover a signaling pathway involved in this process the DAF-16 pathway was analyzed. RESULTS It was found that the extract has no toxicity and is still able to prolong longevity in concentrations of 50 and 100µg of GAE/mL. It was able to protect against damage from the juglone, temperature and UV radiation. This effect is mediated by the activation of the translocation of the DAF-16 factor to the cell nucleus and subsequent activation of defense pathways. CONCLUSIONS Together, it is possible to verify that the extract of jaboticaba is important for the protection of the damages to which were daily exposed, in order to decrease the free radicals and consequently the damages that lead to aging and/or the appearance of diseases.

Abstract
Pitanga, a fruit of the pitangueira tree (Eugenia uniflora L.), is native to Brazil and has a high antioxidant capacity due to the elevated amount of anthocyanins. The present study aimed to investigate the chemical composition of the purple pitanga fruit and to evaluate its antioxidant effect in the nematode Caenorhabditis elegans. We observed that the ethanolic extract of purple pitanga did not cause any toxic effects but notably increased worm lifespan. The extract improved the survival, reproduction and lifespan of the worms in pre- and post-exposure to stressors H2O2 and juglone, as well as improved the lifespan of the oxidative stress hypersensitive strain mev-1. Notably, PPE extract decreased reactive oxygen species by DCF-DA probe and protein carbonyl content from worms stressed with H2O2. The extract also affected the expression of superoxide dismutase SOD-3 and heat shock protein HSP-16.2 levels, daf 16 target genes that modulate lifespan and antioxidant metabolism. In addition, we demonstrate that these effects are dependent on DAF-16, as PPE extract did not provide protection in daf-16 mutants. Therefore, these results suggest that PPE significantly protected against oxidative stress modulating daf-16 target genes.

Abstract
O doping genético caracteriza-se pelo uso não terapêutico de células, genes e elementos gênicos, ou a modulação da expressão gênica com objetivo de aumentar o desempenho esportivo. Isto somente pode ser realizado através de manipulação gênica. Esta prática dopante caracteriza-se como virtualmente "indetectável", o que representa novos desafios analíticos para sua detecção. Esta revisão apresenta o doping genético e possíveis métodos de detecção para evitar futuras fraudes desportivas.
