There is evidence to support a relationship between oxidative stress and protease release in "ischemia-reperfusion damage." We have proposed that aprotinin may exert an antioxidant effect. A double blind clinical trial was performed with a control (G-1) and treated (G-2) groups, both submitted to CMCS. Blood samples were taken 5 times. Biochemical(More)
BACKGROUND Aprotinin has been used in cardiosurgery as a hemostatic agent. Considering the implication of oxygen reactive species and proteases in the pathogenesis of Systemic Inflammatory Response Syndrome, we hypothesized that aprotinin may exert an antioxidant effect. This work was designed to evaluate the antioxidant capacity of aprotinin in vitro and(More)
There is a need for a method to facilitate the development of novel, reproducible colloidal surface-enhanced Raman scattering (SERS) substrates to encourage the use of SERS in applied studies. In this study we show for the first time that by using suitably designed SERS experiments in conjunction with multivariate analysis of variance (MANOVA), an objective(More)
