RED CELLS Identification of the receptor scavenging hemopexin-heme complexes
Heme released from heme-binding proteins on internal hemorrhage, hemolysis, myolysis, or other cell damage is highly toxic due to oxidative and proinflammatory effects. Complex formation with hemopexin, the high-affinity heme-binding protein in plasma and cerebrospinal fluid, dampens these effects and is suggested to facilitate cellular heme metabolism. Using a ligand-affinity approach, we puri...
متن کاملAntioxidant and Free Radical Scavenging Potential of Yakuchinone B Derivatives in Reduction of Lipofuscin Formation Using H2O2-Treated Neuroblastoma Cells
Background: The progressive accumulation of misfolded and aggregated proteins in neurons is an accepted mechanism in aging. Overproduction of reactive oxygen species (ROS), referred to as oxidative stress, is currently believed to play a pivotal role in this process. Lipofuscin as a histological index of aging results from cross-links between oxidized proteins and lipids. Therefore, to attenuat...
متن کاملAnaesthetic gas Scavenging
ThEATRE Possible adverse health effects are an increased risk of spontaneous abortion in females, the increased likelihood of male anaesthetists to father daughters, decreased fertility, a potential increase in haematological malignancy, renal and liver dysfunction and decreased mental performance. One explanation for these effects is inhibition of methionine synthase by nitrous oxide, causing ...

restoring fucosylation. In the absence of fucose, the FX / mice display a profound neutrophilia. Part of this neutrophilia can be explained by loss of selectin ligands (Sialyl Lewis x contains fucose), but proliferation of myeloid progenitor cells suggests that myelopoiesis is being stimulated. Zhou and coworkers have now examined the proliferation of myeloid lineages in FX / mice and attribute...
