aBSTRACT: Several chemicals occur together in the environment as a result of different sources. However, in the great majority of risk assessments only a single chemical is considered. Diflubenzuron (DFB), the most used compound to combat parasites in aquaculture, can be toxic for non-target species. When degraded, it generates p-chloroaniline (PCA), a potentially carcinogenic and mutagenic compound. This study analyzed the activity of the enzymes: Catalase (CAT), acid and alkaline Phosphatase (ACP/ALP) of the gills of the Tilapia fish (Oreochromis niloticus) exposed to different concentrations of the mixture of DFB and PCA in the presence and absence of soil. |

Marine sponges (Porifera) have drawn the attention from a broad number of researchers all over the world. These animals and their simbionts are specialized in chemical warfare, producing biologically active chemical substances as an effective defense against predators. They have been considered a goldmine to chemists, from which have been discovered more than 6000 novel structures; many of them, with enormous biomedical applications, mainly against cancer, but also against bacteria, viruses and other diseases. Some of the sponge-derived drugs are available in the market, such as: Ara-A (antiviral) and Ara-C (anticancer), but there are diverse bioactive compounds under clinical trials. In Cuba, the researches related to the isolation of compounds from... |
