This study examined the role of aldose reductase (AR) in diabetes-associated impaired nerve regeneration using thy1-YFP (YFP) mice. Sciatic nerves of nondiabetic and streptozotocin-induced diabetic AR(+/+)YFP and AR(-/-)YFP mice were transected after 4 weeks of diabetes. Wallerian degeneration and nerve regeneration were evaluated at 1 and 2 weeks(More)
The neural and glial cells of the intrinsic ganglia of the enteric nervous system (ENS) are derived from the hindbrain neural crest at the vagal level. The Hoxb3 gene is expressed in the vagal neural crest and in the enteric ganglia of the developing gut during embryogenesis. We have identified a cis-acting enhancer element b3IIIa in the Hoxb3 gene locus.(More)
We performed a systematic investigation on the dynamic behavior of conduction filaments (CFs) in WO₃-x-based devices. It was found that the electric forming produced an electric structure consisted of a conductive channel (virtual cathode) started from cathode and an insulating band surrounding anode. Both the virtual cathode and the insulating region(More)
