Albertsson et al., [31] and Weiland et al., [19] observed a reduction in carbonyl group after 150 days of incubation with a mixed fungal culture.
Therefore, the carbonyl test was undertaken to verify the oxidation of proteins and it demonstrated a significant increase in this parameter in the kidneys and liver.
The quantitative assessment in this work was performed by calculating the carbonyl index of the samples using (1), adapted from Roy et al.
Average particle size of magnetic fillers: micro- and nanosized magnetite as well as carbonyl iron powder were measured with Zetasizernano S90--Malvern Instruments.
Carbonyl protein was determined by the method described in Levine et al.
To achieve the quantitative analysis of low molecular carbonyl compounds, the standards gas was made by the gasification of standards solution in a 2 L glass container as described in our previous study [21].
At the higher concentrations of this range, small broadenings of the 2-pyrrolidone carbonyl stretching absorptions on the lower wavenumber side were observed when the 2-pyrrolidone was treated with [C.sub.60] and [C.sub.70].
Interestingly, while the GO and SGO groups had significantly lower protein carbonyl concentrations compared to the reference group, only the GO group had higher 3-nitrotyrosine compared to the reference group.
