Levosimendan enhances force generation of diaphragm muscle from patients with chronic obstructive pulmonary diseaseHieronymus W H van Hees
Department of Pulmonary Diseases, Radboud University Nijmegen Medical Centre, Nijmegen, The Netherlands
Am J Respir Crit Care Med 179:41-7. 2009..The effects of levosimendan on skeletal muscle contractility are unknown. Patients with chronic obstructive pulmonary disease (COPD) suffer from diaphragm weakness, which is associated with decreased calcium sensitivity...
Low-tidal-volume mechanical ventilation induces a toll-like receptor 4-dependent inflammatory response in healthy miceMichiel Vaneker
Department of Anesthesiology, Radboud University Nijmegen Medical Centre, P O Box 9101, 6500 HB Nijmegen, The Netherlands
Anesthesiology 109:465-72. 2008..A role for proinflammatory pathways has been proposed. The current studies analyzed the roles of Toll-like receptor (TLR) 4 and TLR2 involvement in the inflammatory response after MV in the healthy lung...
