textile effluents contain different kinds of chemical dyes and many mutagenic and carcinogenic substances. discharge of these effluents into terrestrial and aquatic ecosystems causes harmful effects. in this research, decolorization of a textile effluent by nineteen different strains of fungi was investigated. removal activity of dyes was in order of   aspergillus > rhizopus > fuzarium > penici...

A dietary regimen containing the carcinogen N-2@fluorenyl acetamide for the induction of hyperplastic hepatic nodules and hepatocellular carcinomas is presented. Administration of the carcinogen for 3 months yields a high number of nodules that regress after withdrawal of the carcinogen, and the in@ cidence of hepatocellular carcinomas is very low. Feeding of the carcinogen for 1 additional mon...

The intramolecular asymmetric cyclization of aldehydes has been accomplished using singly occupied molecular orbital (SOMO) catalysis. Selective oxidation of chiral enamines (formed by the condensation of an aldehyde and a secondary amine catalyst) leads to the formation of a 3π-electron radical species. These chiral SOMO-activated radical cations undergo enantioselective cyclization with an ar...
