Portuguese students' knowledge of antibiotics : a cross-sectional study of seco...
Azevedo, Maria Manuel; Pinheiro, C??line; Yaphe, John; Baltazar, F??timaBACKGROUND: Recent surveys show that the knowledge of the general public about the correct use of antibiotics is limited. This contributes to the problem of inappropriate antibiotic use, leading to a progressive loss of bacterial sensitivity to these drugs and the spreading of resistant strains of bacteria. METHODS: In this cross-sectional study, a questionnaire about antibiotic use was given to a sample of stu...
Toxicity of metals in aquatic hyphomycetes : cellular targets and defense mecha...
Azevedo, Maria ManuelTese de Doutoramento em Ciências ; Human activities contribute to a high release of heavy metals to the environment at rates and concentrations sufficient to make them pollutants. Certain metals, such as Cu and Zn, are needed for the growth and metabolism of organisms, while others, as Cd, have no recognized biological functions. However, above critical levels, both essential and non-essential metals became to...
