the complex formation reaction between iodine with tetrabutylammonium halides (tbax) has been studied spectrophotometrically in chloroform solution at 25ºc. various aspects of the spectra of iodine in the presence of various concentration of different tetrabutylammonium halides have been discussed in terms of electronic specifications of iodine and halides. in the case of tetrabutylammonium iod...

Spectral optical properties in different kinds of water were studied at several islands in French Polynesia. Optical differences between the waters of a high island (Moorea, Society archipelago), an atoll (Takapoto, Tuamotu archipelago) and the ocean above the outer reef slope were first assessed in terms of irradiance and diffuse attenuation coefficients. These differences were analysed with r...

-The hydrolysis of transand cts-stilbene oxide and benzo[a]pyrene-4,5-oxlde was measured m cytosol and mlcrosomes of liver, kidney, and testis of control and clofibrate-fed rats Significant levels of nonprotein sulfhydryls were detected in cytosol from hver (4.6 mM) and testis (1 5 mM) Glutathxone was moderately stable m these fractions and Interfered with the partmon assays as conjugates were ...

This investigation examined the effect of the anthracycline antitumor agents on reactive oxygen metabolism in rat heart. Oxygen radical production by doxorubicin, daunorubicin, and various anthracycline analogues was determined in heart homogenate, sarcoplasmic reticulum, mitochondria, and cytosol, the major sites of cardiac damage by the anthracycline drugs. Superoxide production in heart sarc...
