BACKGROUND Previous studies have suggested that occupational exposure to styrene is associated with increased serum levels of the anterior pituitary hormone prolactin (PRL). AIMS To test the hypotheses that: (1) the effect of styrene exposure on PRL secretion is an acute effect, not a subchronic or chronic effect; (2) blood styrene, as a measure of absorbed dose, is a stronger predictor of se...

ALDH2 is involved in the metabolism of styrene, a widely used industrial material, but no data are available regarding the influence of this enzyme on the metabolic fate as well as toxic effects of this chemical. In this study, we recruited 329 workers occupationally exposed to styrene and 152 unexposed controls. DNA strand breaks, DNA-base oxidation in leukocytes and urinary 8-hydroxydeoxyguan...

In this study, we aim to evaluate the shape memory effect of a Poly (Caprolactone) (PCL) (40%) and Styrene-Butadiene-Styrene (SBS) (60%) blend. Shape cycle tests are performed at different temperatures detect best recovery rate. Under appropriate temperature, blend recovers substantially its original shape. To study rate evolution, multi realized with controlled temperature. The results indicat...
