Karabulut Aziz - - 2005
OBJECTIVE: Amino-terminal probrain natriuretic peptide (NT-proBNP), a biologically inactive derivative of BNP, is clinically more useful owing to its longer half-life, higher plasma concentrations, lesser variation among individuals, and higher in vitro stability. In this regard, NT-proBNP may be a better indicator of the severity of ventricular dysfunction. In this ...

OBJECTIVE: Eicosanoids play a key role in the regulation of inflammation and fibrosis. Recently we showed that levels of 5-lipoxygenase (5-LOX)-derived proinflammatory/profibrotic leukotrienes are elevated in bronchoalveolar lavage (BAL) fluid from patients with scleroderma lung disease (SLD). The present study was undertaken to investigate whether increased levels of leukotrienes are ...
