Schwann cells (SCs) are necessary for peripheral nerve regeneration due to their plasticity and trophic supply after sciatic nerve injury (SNI). However, the multiple adaptations of SCs are still poorly understood. This study explored the effects of transient axonal glycoprotein type-1 (TAG-1) on cell migration and neuropilin1 (NRP1) expression in SCs and examined the impact of TAG-1 on nerve regeneration in rats with SNI.

The Quaternary sediment in the Ningbo Coastal Plain was the deposit due to sea-land interaction, which recorded information of past climate changes. The region is therefore an ideal area to study paleoclimate changes and sedimentary characteristics. We determined the stratigraphic division and paleoenvironmental evolution based on C and paleomagnetic dating, along with detailed analyses of lithology, pollen assemblage, foraminifera and ostracodes assemblage, and grain size of sediment in core Z02 located in the southeastern Ningbo Coastal Plain.
