(b) GO biological process analysis of metabolite‐related proteins. The modified neurologic severity score, body weight, brain edema, and lesion volume were evaluated at various time points after TBI. Female rats are more susceptible to the inhibition of VMAT-2 after TBI, which leads to a more severe deficit in female rats when the function of DA-storage and VMAT-2 is inhibited after TBI . Traumatic brain injury (TBI) is a major cause of persistent disabilities such as sleep-wake disorders (SWD). polytrauma). PLoS One. Clinical and Experimental Pharmacology and Physiology, 33, 725–733. However, despite the availability of MRI, the natural history of experimental TBI lesions is not well described in the literature.

Here, we found that TBI-challenged rats showed significant brain injuries characterized by the increase of BBB permeability, brain edema and lesion volume as well as neurological dysfunction, which was significantly attenuated by 2% H (2) treatment. Rodent studies of SWD after TBI are scarce, however, because of lack of appropriate TBI models reproducing acceleration-deceleration forces and compatible with electroencephalography/myography (EEG/EMG)-based recordings of vigilance states. In addition, interweaved networks were constructed to show that the development of TBI might be affected by metabolite-related proteins and their protein pathways.
