Aircraft Recirculation Filter for Air-Quality and Incident Assessment.

The current research examines the possibility of using recirculation filters from aircraft to document the nature of air-quality incidents on aircraft. These filters are highly effective at collecting solid and liquid particulates. Identification of engine oil contaminants arriving through the bleed air system on the filter was chosen as the initial focus.

Effects of enalapril, tempol, and eplerenone on salt-induced hypertension in dahl salt-sensitive rats.

The renin-angiotensin-aldosterone system (RAAS) has been implicated in the pathophysiology of salt-induced hypertension. Angiotensin converting enzyme inhibitors, angiotensin II-type 1 receptor blockers, and aldosterone receptor blockers are used to treat hypertension and congestive heart disease. In addition to their blood pressure lowering effects, they appear to protect against myocardial, renal, and vascular damage.
