Graphenes are an emerging class of carbon nanomaterials whose adsorption properties toward organic compounds have not been well understood. In the present study, graphene nanosheets were prepared by reoxidation and abrupt heating of graphite oxide, which was prepared by sequential chemical oxidation of commercial nonporous graphite powder. Adsorption properties of three aromatic compounds (naph...

We have quantitated the production of thymine glycols in DNA following treatment of cultured human fibroblasts or DNA in solution with the carcinogen A/-hydroxy-2-naphthylamine. Thy mine glycols, detected by using a monoclonal antibody specific to this base damage, were produced in DNA in a dose dependent manner both in vitro and in vivo. Exposure of DNA to W-hydroxy2-naphthylamine in the prese...

Serological reactions of azoproteins from p-aminodiphenyl, beta-naphthylamine, beta-anthramine and some compounds containing two benzene rings (aminodiphenyl methane etc.) have been described, the last mentioned substances having been the subject of theoretical discussion on serological specificity.

This report studies 100 cases of occupational bladder cancer which were reported between 1949 and 1970 by large companies producing dye. It is estimated that in fact a great many more than 100 cases may have developed during the 56 years from 1914 to 1970, as this period corresponds with the beginning of dye production to the termination of benzidine and beta-naphthylamine manufacture in Japan....

Most common urinary system cancer is the Bladder cancer(BC), more in men (M/F: 3), associated with both genetic and environmental factors.,two most well-known factors are smoking occupational exposures.Smoking 25-65% of BC cases, %50 average. Urothelial cancers occupations that use paint, textiles, rubber petroleum products. Among chemical substances; O-toluidine, 2-naphthylamine, benzidine, 4-...

A new series of blue photoluminescent aromatic polyesters (polyarylates) were synthesized from 1-[N,N-di(4-carboxyphenyl)amino]naphthalene with various bisphenols by the diphenylchlorophosphate (DPCP) activated direct polycondensation in a medium of pyridine and lithium chloride. The synthesis, basic characterizations, photoluminescence and electrochemical properties of this series of novel pol...
