Data were obtained from a 2005.65 g rattlesnake at 30°C, 1 h after surgery (black circles) and 10 days after surgery (open circles). (A) R–R interval (RRI). The augmented RRI with greater dispersion 10 days after surgery...

... the recovery of walking in Drosophila melanogaster following leg amputation. Whereas flies pre-amputation explore open arenas in a symmetric fashion on average, foreleg amputation induces a strong turning bias away from the side of the amputation. However, we find that unbiased walking behavior returns over...

... Recoil Recovery Animals moving through natural habitats commonly encounter compliant substrates ( Demes et al., 1995 ; Gilman et al., 2012 ; Gilman and Irschick, 2013 ), which yield when subjected to force, resulting in the absorption of mechanical energy. While some substrates, such as mud...

The mechanisms underlying chilling injuries and the subsequent recovery...

These data show that acclimation to hypoxia has a direct effect on cod myocardial function and/or physiology, and suggest that the cod...

... ), temperature and lactate levels on PCr recovery in vivo . High-intensity exercise resulted in a significantly lower pH i compared with hypoxia exposure and the rate of PCr depletion and tissue acidification during hypoxia exposure was significantly higher in carp held at 25°C compared with those at 15°C...

... in Astronotus ocellatus to investigate the cellular mechanisms behind hypoxia-induced metabolic depression and recovery. RoMR was significantly depressed, by approximately 50%, when dissolved oxygen levels reached 10%saturation (0.67±0.01 mg l –1 at 28±1°C). This depression in RoMR was accompanied by a 50–60...

During both chemical and true anoxia p44ERK was inhibited and recovery resulted in robust reactivation of p44ERK...

In addition, dark aerobic fibers of adults,which rely on aerobic metabolism for both contraction and recovery, grow as large as the white fibers. These large aerobic fibers are subdivided, however,thus...

During a dive, expression of all three Hsps examined remained at control levels for at least 12 h in all tissues examined except the liver, where Hsp72 showed a decrease at 12 h, reaching a significant threefold decrease by 24 h. Brain...
