Experiments of a flexible filament in the wake of a cylinder and in free stream were conducted in a vertical soap film tunnel. The experiments distinctly visualized the movement of the filament. Based on the experimental kinematic results, a 2-d panel method was used to calculate the forces acting on the filament. The experiment and numerical results revealed that different from that in free stream, the filament in Karman vortex street flapped at the same frequency as the vortex street, and with smaller amplitude and larger curvature. The filament suffered an evident thrust in Karman vortex street, while a drag appeared in the case of free stream. The dependence of the drag coefficient on the phase relation between the movement of the filament and the Karman vortex street was also studied.

The expression of immediate early gene plays a pivotal role in rat hepatocyte proliferation from G0 to G1 phases and the progression through G1 phase of the cell cycle within several hours after 2/3 hepatectomy. We investigated the different gene expressions within 1 h after 2/3 hepatectomy by representational difference analysis. Sequence analysis indicated that PC3 induced by NGF was a kind of immediate early gene and might be correlated with liver regeneration. Moreover, we found that 2/3 hepatectomy could induce the expressing of PC3 mRN A by Northern blot with a peak 1-2 h after surgery. In primary cultures of rat hepatocytes, addition of EGF resulted in rapid and transient induction of PC3 mRNA. It was first reported that PC3 gene belongs to immediate early gene associated with liver regeneration.
