There is considerable concern regarding the biological plausibility of the response of certain chemicals in the in vitro photoclastogenicity assay, suggesting that this assay is oversensitive and lacks specificity. To explore this further, four coded compounds (aminotriazole, propantheline bromide, cycloheximide and disulfoton) were evaluated for their potential response in a photoclastogenicit...

Catalases from 16 different organisms including representatives from all three phylogenetic clades were purified and characterized to provide a comparative picture of their respective properties. Collectively the enzymes presented a diverse range of activities and properties. Specific activities ranged from 20,700 to 273,800 units per milligram of protein and maximal turnover rates ranged from ...

In this work, aminotriazole-modified microcrystalline cellulose microsphere (3-ATAR) containing an abundant nitrogen content as promising adsorbent was prepared via a radiation grafting method for the selective recovery ReO4- in presence of UO22+ acidic solution. A series batch and column adsorption experiments including monocomponent binary systems were designed evaluating separation performan...

Aminotriazole (ATZ) is commonly used as a catalase (CAT) inhibitor. We previously found ATZ attenuated oxidative liver injury, but the underlying mechanisms remain unknown. Acetaminophen (APAP) overdose frequently induces life-threatening oxidative hepatitis. In the present study, the potential hepatoprotective effects of ATZ on oxidative liver injury and the underlying mechanisms were further ...
