  • Photodynamic action of Benzo[a]pyrene in K562 Cells 

    Filgueira, Daza de Moraes Vaz Batista; Freitas, Diana Paula Salomão de; Votto, Ana Paula de Souza; Fillmann, Gilberto; Monserrat, José María; Monserrat, Laura Alicia Geracitano; Trindade, Gilma Santos (2007)
    Benzo[a]pyrene (BaP) is ubiquitously distributed in the environment, being considered the most phototoxic element among polycyclic aromatic hydrocarbon (PAHs). In presence of oxygen, PAHs can act as a photosensitizer by ...

  • Physiological and antioxidant enzyme responses to acute and chronic exposure of Laeonereis acuta (Polychaeta, Nereididae) to copper 

    Monserrat, Laura Alicia Geracitano; Monserrat, José María; Bianchini, Adalto (2002)
    Chronic (14 days) and acute (48 h) copper effects on the antioxidant defense system and some physiological variables of Laeonereis acuta (Polychaeta, Nereididae) were evaluated. In both assays, two nominal copper concentrations ...

  • Pollution biomarkers in estuarine animals: Critical review and new perspectives 

    Monserrat, José María; Martínez, Pablo Elías; Monserrat, Laura Alicia Geracitano; Amado, Lílian Lund; Martins, Camila De Martinez Gaspar; Pinho, Grasiela Lopes Leães; Chaves, Isabel Soares; Cravo, Marlize Ferreira; Lima, Juliane Ventura; Bianchini, Adalto (2007)
    In this review, recent developments in monitoring toxicological responses in estuarine animals are analyzed, considering the biomarker responses to different classes of pollutants. The estuarine environment imposes stressful ...

  • Scientometric analysis of Latin American environmental studies 

    Monserrat , Laura Alicia Geracitano; Chaves, Isabel Soares; Monserrat, José María (2009)
    The objective analysis of scientific production is analysed by scientometric methods that measure the development and progress in science through the analysis of productivity and impact of the scientific production in ...

  • Seasonal and organ variations in antioxidant capacity, detoxifying competence and oxidative damage in freshwater and estuarine fishes from Southern Brazil 

    Rocha, Alessandra Martins da; Freitas, Diana Paula Salomão de; Burns, Marcelo Dias de Mattos; Vieira Sobrinho, João Paes; Torre, Fernando De La; Monserrat, José María (2009)
    This study analyzed biochemical biomarkers of freshwater and estuarine fish species from Southern Brazil. It analyzed three organs (muscle, liver and gills), in four fish species (Micropogonias furnieri, Pimelodus ...

  • Sensitivity to microcystins: a comparative study in human cell lines with and without multidrug resistance phenotype 

    Votto, Ana Paula de Souza; Renon, Viviane Plasse; Yunes, João Sarkis; Rumjanek, Vivian Mary Barral Dodd; Capella, Marcia Alves Marques; Moura Neto, Vivaldo; Freitas, Marta Sampaio de; Monserrat, Laura Alicia Geracitano; Monserrat, José María; Trindade, Gilma Santos (2007)
    Multidrug resistance (MDR) is an obstacle in cancer treatment. An understanding of how tumoral cells react to oxidants can help us elucidate the cellular mechanism involved in resistance. Microcystins are cyanobacteria ...

  • The benefits and drawbacks of nicotine exposure in the cortex and hippocampus of old rats 

    Barros, Daniela Marti; Galhardi, Flora Gagliardi; Ferreira, Josencler Luis Ribas; Guterres, Leandra Borba; Dickel, Odila Eli; Monserrat, Laura Alicia Geracitano; Izquierdo, Ivan Antônio; Monserrat, José María (2007)
    Nicotine is the main alkaloid of tobacco and possesses well-established stimulant effects. Previous reports show that nicotine at low doses improves memory functions, while high doses impair memory. This study aims to ...

  • Toxic effects of microcystins in the hepatopancreas of the estuarine crab Chasmagnathus granulatus (Decapoda, Grapsidae) 

    Pinho, Grasiela Lopes Leães; Rosa, Cristiane Moura da; Yunes, João Sarkis; Luquet, Carlos Marcelo; Bianchini, Adalto; Monserrat, José María (2003)
    Microcystins are toxins produced by cyanobacteria, being toxic to aquatic fauna. It was evaluated alternative mechanisms of microcystins toxicity, including oxidative stress and histopathology in the hepatopancreas of the ...

  • Toxicological responses in Laeonereis acuta (Annelida, Polychaeta) after arsenic exposure 

    Ventura-Lima, Juliane; Sandrini, Juliana Zomer; Cravo, Marlize Ferreira; Piedras, Fernanda Reinhardt; Moraes, Tarsila Barros; Fattorini, Daniele; Notti, Alessandra; Regoli, Francesco; Monserrat, Laura Alicia Geracitano; Marins, Luis Fernando Fernandes; Monserrat, José María (2007)
    Several environmental pollutants, including metals, can induce oxidative stress. So, the objective of this study was to evaluate the effects of arsenic (AsIII, as As2O3) on the antioxidant responses in the polychaete ...

  • Toxin accumulation and biochemical alterations in the estuarine crab Chasmagnathus granulatus (Decapoda, Brachyura) after exposure to microcystins 

    Dewes, Ligia Johansen; Monserrat, José María; Ihara, Priscilla Mieko; Yunes, João Sarkis (2007)
