Synergistic enhancement of the extraction of lanthanoid(III) (Ln) with 2-thenoyltrifluoroacetone (Htta) in benzene has been found by the addition of tris(4-isopropyltropolonato)cobalt(III) (Co(ipt)3). The synergistic effect of Co(ipt)3 was ascribed to the formation of a 1:1 adduct of Ln(tta)3 with Co(ipt)3, i.e., a binuclear complex, in the organic phase. The adduct formation constant (beta s,1...
Nuclear factor kappa B (NF-kappa B) is a transcription factor that regulates expression of several genes coding for inflammatory and immunoregulatory proteins including the neutrophil chemotactic cytokine MIP-2. In previous studies we found that crocidolite asbestos activates the nuclear translocation of NF-kappa B as well as MIP-2 gene expression in rat alveolar type II cells. Here we report t...
The p38 mitogen-activated protein kinase (MAPK) is phosphorylated in response to oxidative stress. Mitochondria in cardiomyocytes increase their generation of reactive oxygen species (ROS) during hypoxia (1-5% O(2)). These ROS participate in signal transduction pathways involved in adaptive responses, including ischemic preconditioning and gene transcription. The present study therefore tested ...
Hyperglycemia increases the production of reactive oxygen species (ROS) from the mitochondrial electron transport chain in bovine endothelial cells. Because several studies have postulated a role for prostaglandins (PGs) in the glomerular hyperfiltration seen in early diabetes, we evaluated the effect of mitochondrial ROS on expression of the inducible isoform of cyclooxygenase (COX-2) in cultu...
Many diabetic patients suffer from a cardiomyopathy that cannot be explained by poor coronary perfusion. Reactive oxygen species (ROS) have been proposed to contribute to this cardiomyopathy. Consistent with this we found evidence for induction of the antioxidant genes for catalase in diabetic OVE26 hearts. To determine whether increased antioxidant protection could reduce diabetic cardiomyopat...
