Senecio brasiliensis impairs eclosion rate and induces apoptotic cell death in larvae of Drosophila melanogaster.

Senecio brasilienis (Spreng) Less., is a species native from Brazil, popularly known as "Maria mole", and known to induce hepatotoxicity due to its high content of Pyrrolizidine alkaloids. Despite its toxicity, this plant is widely used in Brazilian folk medicine.

Anacardium microcarpum extract and fractions protect against paraquat-induced toxicity in Drosophila melanogaster.

Ducke (Anacardiaceae) is a native species of Brazil used in folk medicine for the treatment of several illnesses although its antioxidant activity has been reported , there is no evidence of this effect in an model. Here, we investigated the potential protective effect of hydroalcoholic extract (AMHE), methanol (AMMF) and acetate (AMAF) fraction of against paraquat toxicity on survivorship, locomotor performance, antioxidant enzymes activity and reactive species using . Flies were exposed to the extract or fractions (1 and 10 mg/ml) in the presence or absence of paraquat (5 mM) in sucrose solution for 72 h.

Oxidant effects and toxicity of Croton campestris in Drosophila melanogaster.

Context: Croton campestris A.St.-Hil.

Phytochemical Composition, Antifungal and Antioxidant Activity of Duguetia furfuracea A. St.-Hill.

Unlabelled: Background. Duguetia furfuracea is popular plant used in popular medicine. Hypothesis/Purpose.

Fumigant activity of the Psidium guajava var. pomifera (Myrtaceae) essential oil in Drosophila melanogaster by means of oxidative stress.

The guava fruit, Psidium guajava var. pomifera (Myrtaceae family), is a native plant from South America. Its leaves and fruits are widely used in popular medicine in tropical and subtropical countries.

Drosophila melanogaster - an embryonic model for studying behavioral and biochemical effects of manganese exposure.

Embryonic animals are especially susceptible to metal exposure. Manganese (Mn) is an essential element, but in excess it can induce toxicity. In this study we used Drosophila melanogaster as an embryonic model to investigate biochemical and behavioral alterations due to Mn exposure.
