quote: | Two accused shoplifters got a taste of their own medicine when they sought to clear out of the crime--and found that a passing malefactor had broken into their own car.
Security personnel were in the process of questioning Korin Vanhouten, 47, and Eldon Alexander, 36, at an Ogden, Utah WinCo supermarket, accused of stealing makeup, energy bars and batteries.
At the end of the interrogation, they left with a citation for attempted shoplifting. However, they soon stumbled on to the scene of a successful carlifting, with the awkward discovery that while they were in the WinCo, someone--or several someones--had broken into their car. |
And lmao at the picture of the two.

Although most in vitro studies indicate that silk is a suitable biomaterial for ligament tissue engineering, in vivo studies of implanted silk scaffolds for ligament reconstruction are still lacking. The objective of this study is to investigate anterior cruciate ligament (ACL) regeneration using mesenchymal stem cells (MSCs) and silk scaffold. The scaffold was fabricated by incorporating microporous silk sponges into knitted silk mesh, which mimicked the structures of ligament extracellular matrix (ECM). In vitro culture demonstrated that MSCs on scaffolds proliferated vigorously and produced abundant collagen. The transcription levels of ligament-specific genes also increased with time. Then MSCs/scaffold was implanted to regenerate ACL in vivo. After 24 weeks, histology observation showed that MSCs were distributed throughout the regenerated ligament and exhibited fibroblast morphology. The key ligament ECM components including collagen I, collagen III, and tenascin-C were produced prominently. Furthermore, direct ligament–bone insertion with typical four zones (bone, mineralized fibrocartilage, fibrocartilage, ligament) was reconstructed, which resembled the native structure of ACL–bone insertion. The tensile strength of regenerated ligament also met the mechanical requirements. Moreover, its histological grading score was significantly higher than that of control. In conclusion, the results imply that silk scaffold has great potentials in future clinical applications. |
