A colorimetric assay for NADPH-dependent, mercuric ion-specific oxidoreductase activity was developed to facilitate the investigation of mercuric reductase gene expression in polluted aquatic ecosystems. Protein molecules extracted directly from unseeded freshwater and samples seeded with Pseudomonas aeruginosa PU21 (Rip64) were quantitatively assayed for mercuric reductase activity in microtit...

Precision-cut slices of animal tissue are widely used for pharmacotoxicology, biotrdnsformation and biochemical studies. Tissue slices offer major advantages over other in v i m systems, as the complex heterogeneous architecture of the different cell types that make up the kidney remains intact. During preparation, however, the slices are subjected to oxidative stress and mechanical and physica...
The in vitro cytotoxicity of urethane dimethacrylate composites cured at different times by visible light and after different aging times and extraction treatments was evaluated using succinic dehydrogenase activity in the mitochondria of a fibroblastic cell line to reflect cell viability. In addition, extractable chemicals associated with cell response were identified. The composite samples we...
