Research misconduct? Image duplication? Fabrication? Falsification? Unintentional and inadvertent mistake? Coincidental similarity?

Fig. 3E - LPS+Escin, and OA + Escin (lanes 9 and 11) are identical - enhance the contrast to see it.
Fig. 4B - this is a b-actin blot. It is IDENTICAL to a STAT3 loading control used in Figure 2C of PMID 17505005 (Clin Cancer Res. 2007 May 15;13(10):3024-32.). Something is erased from the top right coner in both images, so we know they're the same.
Fig. 6C - A293, b-actin control for TRADD in left side, is the same as b-actin control for p65 on the right side. Blot has been flipped horizontally between conditions.
Fig. 5B - b-actin control in TNF and TNF+Escin is the same, flipped horizontally. There are even vertical shear-lines on this image, so it is impossible to deny they are identical.
