AVALIAÇÃO DA TOXICIDADE AGUDA DO ANTIBIÓTICO CIPROFLOXACINA AOS CLADÓCEROS DAPHNIA MAGNA E CERIODAPHNIA SILVESTRII

Acute toxicity of thallium to Daphnia magna and Ceriodaphnia dubia.

Toxicological risk assessment of complex mixtures through the WTox model Avaliação do risco toxicológico de misturas complexas através do Modelo WTox

Mathematical models are important tools for environmental management and risk assessment. Predictions about the toxicity of chemical mixtures must be enhanced due to the complexity of effects that can be caused to the living species. In this work, the environmental risk was accessed addressing the need to study the relationship between the organism and xenobiotics. Therefore, five toxicological...

Daphnia magna

The cellular architecture of the Daphnia compound eye visual system was studied by using computer-aided techniques. All the neurons in one half of the bilaterally symmetric optic ganglion (OG) were reconstructed in three dimensions from serial electron micrographs. The techniques employed were those developed by Levinthal and collaborators (Macagno, Levinthal, and Sobel, Ann. Rev. Biophys. Bioe...

The influence of treatment access regulation and technological resources on the mortality profile of acute biliary pancreatitis A influência da regulação do acesso aos serviços de saúde e da incorporação tecnológica no perfil de mortalidade da pancreatite aguda biliar

Purpose: The influence of treatment access regulation and technological resources on the mortality profile of acute biliary pancreatitis (ABP) was evaluated. Methods: The cases seen in a tertiary hospital were studied during two periods of time: 1995-1999 and 2000-2004, i.e., before and after the implementation of medical regulation. Results: Among the 727 patients with acute pancreatitis, 267 ...

Water Quality Assessment in Piracicamirim Creek Upstream and Downstream a Sugar and Ethanol Industry Through Toxicity Tests With Cladocerans

An environmental impact study was conducted to determine the Piracicamirim’s creek water quality in order to assess the influence of effluents from a sugar industry in this water body. For this, toxicity tests were performed with a water sample upstream and downstream the industry using the microcrustaceans Daphnia magna, Ceriodaphnia dubia and Ceriodaphnia silvestrii as test organisms, as well...
