The results suggest that RPL13A and cyclophilin are two appropriate housekeeping genes for the rat pMCAO model up to 21 days. ADAMTS1 mRNA levels increased, but ADAMTS8 decreased after pMCAO. Our data provide new insight into the mechanism of brain ischemia and self-repair after injury.

This paper, based on the two-component slip model, numerically analyzes the tribology performances of journal bearings with boundary slip/no-slip regions on the condition of high speed water lubrication. It is demonstrated that journal bearings with a whole slip sleeve reduce the friction drag and the load carrying capacity. Bearings with a slip/no-slip interval region on sleeve, however, can shorten the cavitation region and enhance the average film pressure, which means the enhancement of load carrying capacity and the reduction of friction drag. When the boundary of the slip and no-slip regions is close to the location between the pressure peak and 180° of the bearing, the load carrying capacity reaches its maximum. Different to loading capacity, friction drag is reduced dramatically with the increase of the slip region. For bearings with small eccentricity ratio, small width and large diameter, the loading capacity and the friction drag can be enhanced and reduced more significantly.
