| The frequent contamination of water resources with drugs comprises one the most important environmental problems. In order to avoid serious disturbances for aquatic life, efficient and economically viable procedures should be developed for removing common pollutants, as paracetamol. From these considerations, the present work evaluated the efficiency of sugar cane bagasse (SCB) and vegetable sponge (VS), two natural adsorbents commonly found in Brazil, for retaining paracetamol molecules dispersed in aqueous solutions. Thus, systems composed of glass columns and peristaltic pumps were optimized and, for pH, the best value was 7.0. After optimisation, adsorption isotherms were built and it was possible to calculate the MAC F values for SCB (120.5 µg/g) and... |

| In this article, we propose a new strategy to build a sensor for easy handling and rapid analysis on-site. Our sensor is based on the combination of surface-enhanced Raman spectroscopy (SERS) and molecularly imprinted polymers (MIPs). SERS provides a strong sensitivity for the detection of trace molecules while MIPs offer a highly selective and specific recognition platform. The research presented here focuses on the detection of the interaction between a robust ultra-thin layer of MIPs and of paracetamol, the targeted molecule. This drug is an environmental emerging pollutant, i.e., a molecule whose presence and significance have not yet been elucidated, which gives rise to health and environmental concerns. The results are a combined analysis of the SERS... |

| Introducción: el rizoma de Zingiber officinale Roscoe (jengibre) familia Zingiberaceae, presenta actividad antioxidante como atrapador de radicales libres y de protección en lipoperoxidación en modelos in vivo e in vitro, debido a sus principales compuestos bioactivos. Objetivo: evaluar el efecto del extracto hidroalcohólico obtenido de Zingiber officinalis en el modelo de hepatotoxicidad por sobredosis de acetaminofén en ratas. Métodos: se preparó un extracto hidroalcohólico del rizoma fresco de Zingiber officinalis. Se utilizaron 42 ratas Wistar, albinas, macho (180-200 g de peso) y se distribuyeron aleatoriamente en 7 grupos (n= 6); 4 grupos fueron administrados con extracto hidroalcohólico vía oral (20,08; 54,58; 148,4 y 244,69 mg/kg) en... |

| ABSTRACT Quercetin has potent antioxidant action and a hepatoprotective role. The aim of this study was to evaluate the hepatoprotective action of quercetin pretreatment in paracetamol-induced liver damage (PILD) and structural injury resulting from partial hepatectomy (PH). In the first model, Wistar rats received oral quercetin (50mg/kg/day) during 8 days. On the 8th day, 3g/kg paracetamol were added. In the second model, the same quercetin dose was given during 7 days and rats were submitted to PH on the 8th day. Blood samples were obtained for determination of enzyme levels. Liver, heart, kidney and lung tissue were also collected for assessment of quercetin biodistribution and/or histological analyses. The results obtained after PILD were more... |
