[The changes of HIF-1α and AMPKα2 expression levels during skeletal muscle blunt injury recovery].

Objective: To explore the possible biological mechanisms of skeletal muscle injury recovery by observing the changes of AMP-activated protein kinase α2 (AMPKα2) and hypoxia inducible factor-1α (HIF-1α) expression levels of rats in the skeletal muscle blunt injury recovery process.

Methods: Six of the 48 male Wistar rats was randomly selected as the normal control group. The blunt injury model was set up by injuring the hind legs of remaining 42 rats with heavy objects.

4-(2,3-Dimeth-oxy-phen-yl)-1H-pyrrole-3-carbonitrile.

The asymmetric unit of the title compound, C(13)H(12)N(2)O(2), obtained in a search for analogs of the fungicide fludioxonil [systematic name: 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-1H-pyrrole-3-carbonitrile], contains two independent mol-ecules, A and B. The benzene and pyrrole rings are inclined to each other at 38.5 (1) and 29.
