Monolayers of photosystem II on gold electrodes with enhanced sensor response--effect of porosity and protein layer arrangement.

J Maly et al.

Analytical and bioanalytical chemistry, 381(8), 1558-1567 (2005-04-12)

Mass transport of the bulk of the analyte to the electrode and through the bioactive layer can be significantly improved by use of the nanoelectrode array and defined arrangement of protein film. This phenomenon has been studied by (i) atomic-force

Effect of chronic hyperoxic exposure on duroquinone reduction in adult rat lungs.

Said H Audi et al.

American journal of physiology. Lung cellular and molecular physiology, 289(5), L788-L797 (2005-07-05)

NAD(P)H:quinone oxidoreductase 1 (NQO1) plays a dominant role in the reduction of the quinone compound 2,3,5,6-tetramethyl-1,4-benzoquinone (duroquinone, DQ) to durohydroquinone (DQH2) on passage through the rat lung. Exposure of adult rats to 85% O2 for > or =7 days stimulates

Investigation of photoinduced electron transfer in model system of vitamin E-duroquinone by time-dependent density functional theory.

Xiao-Hui Duan et al.

The Journal of chemical physics, 120(21), 10025-10032 (2004-07-23)

Photoinduced electron transfer of the model system composed of vitamin E and duroquinone has been investigated using time-dependent density functional theory. Calculations for the excited states tell that the photoexcitation of the model system can directly yield the charge transfer

Electron transfer from heme bL to the [3Fe-4S] cluster of Escherichia coli nitrate reductase A (NarGHI).

R A Rothery et al.

Biochemistry, 40(17), 5260-5268 (2001-04-25)

We have investigated the functional relationship between three of the prosthetic groups of Escherichia coli nitrate reductase A (NarGHI): the two hemes of the membrane anchor subunit (NarI) and the [3Fe-4S] cluster of the electron-transfer subunit (NarH). In two site-directed

Exposure of spermatozoa to duroquinone may impair reproduction of the common carp (Cyprinus carpio) through oxidative stress.

Bingsheng Zhou et al.

Aquatic toxicology (Amsterdam, Netherlands), 77(2), 136-142 (2006-01-18)

Toxicity of many waterborne organic contaminants to aquatic organisms is mediated through oxidative damages resulting from the production of reactive oxygen species (ROS). Using duroquinone as a model ROS inducer, we carried out in vitro and in vivo experiments to
