Within recent years hydrazine and the methyl substituted hydrazines have come into considerable use as rocket fuels. As a result of this increased production of hydrazines, the possibility of accidental human exposure is of considerable interest. Obvious concern results from the fact that hydrazine had been used as an experimental means of producing fatty liver in experimental animals for many ...

Determination of 1, 1-dimethylhydrazine (DMH) in air is carried out by spectrophotometry, GC or HPLC analysis, but in this study DMH was analyzed by a gas sensor based on nanostructure conducting polyaniline. Determination of DMH has been done very simplely and quickly in recent work. Electrically conductive fibers have been prepared by polymerization of aniline on surfaces of commercial polyme...

2-Difluoromethylornithine (DFMO) was administered to 1,2-dimethylhydrazine (DMH)-treated mice to reduce colonic polyamine levels and mucosal hyperplasia. Mice received 1% DFMO in drinking water throughout the experiment and were given injections of DMH (20 mg/kg) weekly for 28 weeks. DFMO inactivated 93% of colonic ornithine decarboxylase activity. Although DMH treatment did not induce colonic ...

While researchers have extensively studied the initial decomposition mechanism of Monomethylhydrazine (MMH, CH3NHNH2) in MMH/dinitrogen tetroxide (NTO) system, investigation Unsymmetrical Dimethylhydrazine (UDMH, (CH3)2NNH2) has been limited due to its high toxicity, corrosiveness, and deterioration rate. Hence, effects UDMH’s products on combustion performance gas-phase reaction mechanisms rem...

β-ionone (βI), a cyclic isoprenoid, and geraniol (GO), an acyclic monoterpene, represent a promising class of dietary chemopreventive agents against cancer, whose combination could result in synergistic anticarcinogenic effects. The chemopreventive activities of βI and GO were evaluated individually or in combination during colon carcinogenesis induced by dimethylhydrazine in 48 3-week-old male...
