متن کاملCirculating MicroRNA-150 Serum Levels Predict Survival in Patients with Critical Illness and Sepsis
BACKGROUND AND AIMS Down-regulation of miR-150 was recently linked to inflammation and bacterial infection. Furthermore, reduced serum levels of miR-150 were reported from a small cohort of patients with sepsis. We thus aimed at evaluating the diagnostic and prognostic value of miR-150 serum levels in patients with critically illness and sepsis. METHODS miR-150 serum levels were analyzed in a...
