Does acute myocardial infarction elevate serine protease activity in saliva of patients with periodontitis?
AMI may be reflected in PMN serine protease elastase activity in saliva, despite its strong association with periodontitis.
This study provides the first evidence that oxidative stress is increased in calcified regions of stenotic aortic valves from humans. Increased oxidative stress is due at least in part to reduction in expression and activity of antioxidant enzymes and perhaps to uncoupled NOS activity. Thus, mechanisms of oxidative stress differ greatly between stenotic aortic valves and atherosclerotic arteries.
