Background: Apoptosis, a mechanism of cell death prominent in critical illnesses including disseminated inflammation and multiorgan dysfunction syndrome, is characterized by morphologic changes including cell shrinkage, condensation of organelles, blebbing, and chromatin fragmentation. These phenomena suggest substantial changes in cytoskeletal structure. We hypothesized that stress-induced apoptosis...
Background. Iron participates in diverse pathologic processes by way of the Fenton reaction, which catalyzes the formation of reactive oxygen species (ROS). To test the hypothesis that this reaction accelerates apoptosis, we used human umbilical vein endothelial cells (HUVECs) as surrogates for the microvasculature in vivo.Methods. HUVECs were loaded with Fe [III](ferric chloride and ferric ammonium...
