Two theories of how energy metabolism should be associated with longevity, both mediated via free-radical production, make completely contrary predictions. The 'rate of living-free-radical theory' (Pearl, 1928; Harman, 1956; Sohal, 2002) suggests a negative association, the 'uncoupling to survive' hypothesis (Brand, 2000) suggests the correlation should be(More)
Peripheral nerves repairing using freeze-thawed skeletal muscle autografts were compared to conventional nerve grafts with respect to their electrical properties. It was found that the amplitude and distal latency of action potentials in both groups were not significantly different 3 and 6 months after the operation. These observations support the thesis(More)
Regeneration of myelinated axons with 1 cm freeze-thawed skeletal muscle autografts was compared with nerve grafts in the rats. Regeneration was assessed histologically and morphometrically in the grafts and distal nerve stumps. Recovery of axon numbers and fibre diameters in distal nerve stumps was similar in the two kinds of grafts 6 months after(More)
