The investigators aim to examine how the skeletal muscles of the human volunteers respond to experimental septic conditions to aid understanding of muscle wasting and its biology.. Six healthy men aged 18-30 will be randomly assigned to two metabolic study visits. On the first visit, while resting on a bed, they will have four cannulae inserted including one in the upper thigh, for blood sampling and the infusion of insulin, glucose and normal and tracer amino acids (which allow us to measure muscle protein metabolism). Subjects will receive either injection of purified bacterial product called lipopolysaccharide (LPS) to induce flu-like symptoms or normal saline according to randomization followed by a metabolic test to stimulate muscle synthesis and glucose transport. Three small samples of muscle will be obtained under local anaesthetic from the thigh to measure molecular events in muscle. By performing these measurements, the investigators will determine the consequences of LPS on muscle production and carbohydrate metabolism.
