Aflatoxin B1 and zearalenone in dairy feeds in Portugal, 2009-2011.

This paper presents 3 years of data (2009-2011) on the occurrence of two mycotoxins, aflatoxin B1 (AFB1) and zearalenone (ZEA), in samples of feedstuff for dairy cows (n = 963), ewes (n = 42), and goats (n = 131) produced in Portugal.

In vitro and in vivo antimalarial activity of essential oils and chemical components from three medicinal plants found in northeastern Brazil.

The prophylactic and therapeutic arsenal against malaria is quite restricted and all the antimalarials currently in use have limitations. Thus, there is a need to investigate medicinal plants in the search for phytochemicals which can be developed into drugs. In our investigation, essential oils (EOs) were obtained from Vanillosmopsis arborea (Gardner) Baker, Lippia sidoides Cham.
