3. Cutinases fúngicas: propriedades e aplicações industriais
Cutinases (EC 3.1.1.74) are also known as cutin hidrolases. These enzymes share catalytic properties of lipases and esterases, presenting a unique feature of being active regardless the presence of an oil-water interface, making them interesting as biocatalysts in several industrial processes involving hydrolysis, esterification and trans-esterification reac

5. Ocorrência de compostos organoclorados (pesticidas e PCBs) em mamíferos marinhos da costa de São Paulo (Brasil) e da Ilha Rei George (Antártica). / Occurrence of organochlorine compounds (pesticides and PCBs) in marine mammals from São Paulo coast (Brazil) and King George Island (Antarctica).
Organochlorine compounds cause strong impact on the nature, as a consequence of three basic characteristics: environmental persistence, bioaccumulation, and high toxicity. The marine mammals are one of the most vulnerable organisms to the chronic toxicity of these contaminants. Besides the high concentration in the body, the female transfers part of her load

6. Genotoxic exposure of workers creosoting wood.
In a small wood preserving industry spot samples were taken from contaminated surfaces at several places and tested for mutagenicity. The results suggest that the application of a wipe test can give a first indication of occupational exposure to mutagenic and carcinogenic substances, particularly when exposure occurs more from skin contact than from inhalati

7. Respiratory cancers and chemical exposures in the wood industry: a nested case-control study.
A cohort of 3805 men who had worked for at least one year in the particleboard, plywood, sawmill, or formaldehyde glue industries between 1944 and 1965 was followed up until 1981. From within the cohort the 57 patients with verified "respiratory" cancer (ICD 7 codes: 160-162.1, 141, 143-8) were defined as "cases," and 171 men without respiratory cancer from
