Axons in both peripheral nerves and central fiber pathways undergo very slow Wallerian degeneration in Wlds mutant mice. It has recently been shown that in Wlds mutant mice there is a delay in the intensification of acetylcholinesterase histochemical staining in the molecular layer of the dentate gyrus following lesions of the entorhinal cortex. Thus, it(More)
The golden Syrian hamster is the model of choice or the only rodent model for studying many human diseases. However, the lack of gene targeting tools in hamsters severely limits their use in biomedical research. Here, we report the first successful application of the CRISPR/Cas9 system to efficiently conduct gene targeting in hamsters. We designed five(More)
Collagen fiber (CF), an abundant natural biopolymer, features many favorable properties that make it a potential carrier for cell immobilization. In the present investigation, CF was grafted with polyethyleneimine (PEI) using glutaraldehyde (GA) as the cross-linking agent, resulting in the formation of a novel CF based carrier (CF-PEI). The properties of(More)
A novel antifungal nano-silver agent (BT-CF-AgNPs) was synthesized by using bayberry tannin (BT) grafted collagen fiber (CF) as support, and the antifungal behaviors of the nano-silver were investigated by using Saccharomyces cerevisiae as a typical fungus. Bayberry tannin (BT), a kind of natural polyphenol, was grafted onto the CF surface to improve the(More)
