In eukaryotes, aberrant expression of transposable elements (TEs) is detrimental to the host genome. Piwi-interacting RNAs (piRNAs) of ∼23 to 30 nucleotides bound to PIWI clade Argonaute proteins silence transposons in a manner that is strictly dependent on their sequence complementarity. Hence, a key goal in understanding piRNA pathways is to determine mechanisms that modulate piRNA sequences....

CONTEXT AND OBJECTIVE: Postoperative infections should be detected earlier. We investigated the effi cacy of the National Nosocomial Infection Surveillance (NNIS) score, interleukin-6 (IL-6) and various acute-phase proteins for predicting postoperative infections. DESIGN AND SETTING: Case series study at the Júlio Müller University Hospital. METHODS: Thirty-two patients who underwent major gast...
