Tissue hyperoxygenation promotes oxidative metabolism in motor unit.

Abstract excerpt

Some mutant hemoglobin (Hb) variants are found with lowered O2 affinity. Low oxygen affinity is reported to increase the O2 availability in peripheral tissues (Kunert et al. [1996] Microvasc. Res. 52:58-68). In the present study, we used a mouse model carrying two low-affinity Hb variants, Titusville and Presbyterian, to evaluate the chronic in vivo influence of lowered oxygen affinity on the neuromuscular...
