The water-resistant behavior and the mechanical properties of the PUU films consisting of POA were enhanced appreciably resulting from the strong hydrogen bonding in urea carbonyl
groups in the hard segments.
Prolonged exposure to organism leads to decrease in carbonyl
index due to biodegradation (biotic) through Norrish type mechanism (Fig.
The samples were stored at refrigerated temperature (4[degrees]C [+ or -] 1[degrees]C) and analysed at three day interval for various parameters (pH, colour and odour score, peroxide, thiobarbituric acid reacting substances [TBARS], total carbonyl
contents and total plate count) up to 9 days.
Two oxidative parameters (carbonyl
and DCFH) were higher in the exposed groups (Group II and III) than in the control group (Group I).

The qualitative assessment was performed by overlapping HATR spectra of the sample at different exposure times and comparing the carbonyl
bands at 1,713 [cm.sup.-1] and the hydroperoxides bands between 3,600 and 3, 200 [cm.sup.-1].
Elastomer mixtures, based on ethylene-octene copolymer filled with micro- and nano-sized iron oxides ([Fe.sub.3][O.sub.4]), carbonyl
iron powder (CIP), and gamma iron oxide ([gamma]-[Fe.sub.2][O.sub.3]) were preliminary prepared by a Brabender measuring mixer N50 (temp.
Objective: To investigate the potential of carbonyl
content as a biomarker for detecting oxidative Deoxyribonucleic acid (DNA) damage induced Antiretroviral Theraphy (ART) toxicity and/or accelerated aging in HIV/AIDS patients.

However, the isomers in low molecular carbonyl
compounds such as acetone/propionaldehyde and butanone/butyraldehyde were difficult to analyze by the APCI-MS/MS due to the same molecular mass.
