In development studies, DTBDS alone provided a ~44 % increase in fouling relative to base fuel and TBHP
provided ~21% increase in fouling relative to base fuel.
and [H.sub.2][O.sub.2], both high and low fluences of UVA, can induce excessive ROS generation in corneal endothelial cells, leading to apoptosis and cell death.
To examine whether these extracts can protect mammalian cells from oxidative stress, cultures of a human mammary gland-derived epithelial cell line MCF-7 were treated with each extract prior to challenging them with tBHP
. The intracellular ROS production was determined by the relative intensity of DCF fluorescence (Figure 2(a)).
The test diet contained 20% of TBHP
and 80% of the reference diet (Table 1).
Tert-butyl hydroperoxide (TBHP
, oxidant), sodium formaldehyde sulphoxylate (SFS, reductant) are used as redox couple to initiate the polymerization process.

The epoxidation with TBHP
and NaClO, H2O2/ Na2WO4aC/2H2O gave the enantioselectivity not more than 15% e.e.
Chemiluminiscence measurement was started by addition of 3 mM t-butylhydroperoxide (TBHP
Este resultado sigue la tendencia observada en la oxidacion de fosfinas con TBHP

Racemic and S-LA were less effective than the R-isomer that was also protective in tertiary butyl hydroperoxide (TBHP
