Extracellular superoxide dismutase (EC-SOD) is an antioxidant enzyme that has been shown to protect the lung from oxidant-mediated damage, inflammation, and interstitial fibrosis. Extracellular matrix (ECM) components, such as collagen and glycosaminoglycans, are known to be sensitive to oxidative fragmentation. Heparan sulfate, a glycosaminoglycan, is highly abundant in the ECM and tightly binds EC-SOD. We investigated the protective role of EC-SOD by evaluating the interaction of EC-SOD with heparan sulfate in the

presence of reactive oxygen species (ROS). We found that ROS-induced heparin and heparan sulfate fragments induced neutrophil chemotaxis across a modified Boyden chamber, which was inhibited by the presence of EC-SOD by scavenging oxygen radicals. Chemotaxis in response to oxidatively fragmented heparin was mediated by Toll-like receptor-4. In vivo, bronchoalveolar lavage fluid from EC-SOD knockout KPT-8602 mw mice at 1, 14, and 28 days after asbestos exposure showed increased heparan sulfate shedding from the lung parenchyma. We demonstrate that one mechanism through which EC-SOD inhibits lung inflammation and fibrosis in asbestosis is by protecting heparin/heparan sulfate from oxidative

fragmentation.”
“Background: Estimated glomerular filtration rate (eGFR) has been demonstrated to predict atherosclerotic vascular disease (ASVD)-associated clinical events independent of traditional vascular risk factors. Recent studies have demonstrated that eGFR decline over time may improve prediction of ASVD-associated mortality risk in chronic PP2 order kidney disease (CKD) patients.\n\nAim: The aim of this study is to evaluate the association between 5-year change in eGFR with renal disease and ASVD-associated clinical events.\n\nDesign: Prospective observational study.\n\nMethods: A total of 1012 women over the age of 70 years from the Calcium Intake Fracture Outcome Study were included. Baseline characteristics including baseline and 5-year creatinine, participants’ comorbidities and complete verified 10-year records for ASVD and renal disease-associated hospitalization and/or mortality were obtained using the Western Australian Data Linkage

System.\n\nResults: Participants were stratified according to annual rate of eGFR change in quartiles [-1.2 (first quartile), >-1.2 to 0.1 (second quartile), > 0.1-1.7 (third MEK inhibitor quartile) and > 1.7 ml/min/1.73 m(2)/year (fourth quartile)]. In the adjusted model, compared with participants in the fourth quartile, those in the first and/or second quartiles of annual eGFR change had significantly higher risk of renal disease and/or ASVD-associated clinical events. However, the association with renal clinical events was more pparent in participants with baseline eGFR of < 60 ml/min/1.73 m(2).\n\nConclusion: The results of this study suggest that the inclusion of long-term eGFR change over time might augment prognostication for renal disease and ASVD-associated clinical events in elderly women.
