Myocardial hypertrophy is prevented by farnesol through oxidative stress and ERK1/2 signaling pathways.

Farnesol is a sesquiterpene found in several plants, with multiple pharmacological activities. However, pharmacological actions of farnesol in the treatment of cardiac hypertrophy are not yet reported. This study aimed to investigate the effect and regulatory mechanisms of farnesol against isoproterenol-induced pathological cardiac hypertrophy.

A potential link among antioxidant enzymes, histopathology and trace elements in canine visceral leishmaniasis.

Canine visceral leishmaniasis (CVL) is a severe and fatal systemic chronic inflammatory disease. We investigated the alterations in, and potential associations among, antioxidant enzymes, trace elements and histopathology in CVL. Blood and tissue levels of Cu-Zn superoxide dismutase, catalase and glutathione peroxidase were measured in mixed-breed dogs naturally infected with Leishmania infantum chagasi, symptomatic (n = 19) and asymptomatic (n = 11).
