2. Evaluating antimicrobial and antioxidant capacity of endemic Phlomis russeliana from Turkey and its antiproliferative effect on Human Caco-2 Cell Lines
Abstract: In this study, the antimicrobial, antioxidant and antitumor activity of ethanol extracts obtained from Phlomis russeliana (Sims.) Lag. ex Benth. (Lamiaceae) were evaluated. Disc diffusion and microdilution methods were used to test the extracts for antimicrobial activity against seven bacteria strains (Bacillus cereusATCC 7064, Bacillus subtilisATC

9. Exposure to particulate matter 2.5 mM collected at high traffic routes in Rio de Janeiro city: evaluation mutagenic, genotoxic and determination of health risks induced by polycyclic aromatic hydrocarbons / Exposição ao material particulado 2,5 m coletado em vias de alto tráfego da cidade do Rio de Janeiro: avaliação mutagênica, genotóxica e determinação de risco à saúde induzido por hidrocarbonetos policíclicos aromáticos
The mutagenicity of airborne particles from combustion is attributed primarily to polycyclic aromatic hydrocarbons (PAHs). We investigated the mutagenic activity of particulate matter (PM2.5) samples collected from three sites in Rio de Janeiro. Samples were collected using a high-volume sampler at Avenida Brasil, the campus of the Rio de Janeiro State Unive
