..., we investigated whether muscle protein degradation is increased in critically ill patients with sepsis and which proteolytic enzyme systems are involved in this degradation. Eight patients and seven healthy volunteers were studied. In vivo muscle protein kinetics was measured using arteriovenous...

...S. B. Ireland; P. M. Stewart 1. The effect of uraemia on the rates of protein synthesis and protein degradation in liver, heart and vastus lateralis muscle were examined in the rat. Uraemia was induced by a five-sixths nephrectomy and the rates of protein turnover were compared with pair-fed sham...
