[Effects of heavy-load exercise on skeletal muscle cells apoptosis and mechanisms of mitochondrial apoptosis in rats].

Objective: To analyze the molecular mechanisms of skeletal muscle cells apoptosis induced by heavy-load exercise with Omi as the entry point.

Methods: One hundred and twenty-six adult SD rats were randomly divided into five groups: control group(C), eccentric exercise group (E), simple blocking group (U), DMSO group (D) and exercise block group (EU). In addition to the C group, the other four groups were randomly divided into 0 h after experiment, 12 h after experiment, 24 h after experiment, 48 h after experiment and 72 h after experiment with 6 rats in each group.

[Effects of different types of exercise on contractile properties and expressions of MuRF1, PGC-1α /FNDC5 in soleus muscle of unloaded rats].

To investigate the effects of aerobic versus resistance exercise on soleus muscle contractile properties and the expressions of MuRF1, PGC-1α and FNDC5 in amyotrophic rats after unloading, and the possible molecular biological mechanisms. Male Wistar rats were randomly divided into recovery group (CT), aerobic exercise group (A), resistance exercise group (R) and control group (C), with 6 rats in each group. The control group did not receive any treatment.

The nymph, habitat, and status of in China (Ephemeroptera: Ephemeridae).

The nymphs of a new species of Eatonigenia have more modified labrum and smaller foreclaws than congeners, and the males have a more reddish-brown colored body, cerci, genitalia and more sclerotized projections of gonopores. These characters indicate a new species which is named E. zhangi sp.

The complete mitochondrial genome of Paegniodes cupulatus (Ephemeroptera: Heptageniidae).

The complete mitochondrial genome of Paegniodes cupulatus (Ephemeroptera: Heptageniidae), which is sequenced for the first time here, is 15,715 bp in length, containing 13 protein-coding genes, 2 rRNAs, 22 tRNAs and a control region. The overall base composition of the genome is 33.1% for T, 20.
