TL;DR: In this paper, postoperative cognitive dysfunction may be related to the systemic inflammatory response and an increase in serum markers of brain injury such as S100B protein and neuron-specific enolase (NSE).
High Dose of N-Acetylcystein Prevents Acute Kidney Injury in Chronic Kidney Disease Patients Undergoing Myocardial Revascularization
Eduesley Santana-Santos,Luis Henrique W. Gowdak,Fábio Antônio Gaiotto,Luiz Boro Puig,Ludhmila Abrahão Hajjar,S Zeferino,Luciano F. Drager,Maria Heloisa Massola Shimizu,Luiz Aparecido Bortolotto,José Jayme Galvão de Lima +9 more
