Protein complexes represent major functional units for the execution of biological processes. Systematic affinity purification coupled with mass spectrometry (AP-MS) yielded a wealth of information on the compendium of protein complexes expressed in Saccharomyces cerevisiae. However, global AP-MS analysis of...

From a previously validated paediatric population pharmacokinetic model, it was derived that non-linear morphine maintenance doses of 5 μg/kg(1.5)/h, with a 50 % dose reduction in neonates with a postnatal age (PNA) <10 days, yield similar morphine and metabolite concentrations...
