Agro-ecosystem models have been widely used to quantify soil organic carbon (SOC) dynamics based on digital soil maps. However, most of the studies use soil data of single or limited choices of map scales, thus the influence of map scales on SOC dynamics has rarely been quantified. In this study, six digital paddy soils databases of the Tai-Lake region in China at scales of 1:50,000 (P005), 1:2...

Previous studies have demonstrated that depletion of Gas7 impedes neurite outgrowth in primary cultures of Purkinje neurons, and that Gas7 promotes neurite outgrowth in PC12 cells. To investigate the physiological function of Gas7, we generated by homologous recombination a Gas7-mutant mouse which produced a Gas7 variant protein with an in-frame deletion of amino acid residues 103–120. Only low...

While adult neurogenesis in mammals is mainly restricted to two telencephalic zones, in teleost fishes, neurogenesis has been observed in many brain areas. Hence, the medaka (Oryzias latipes) represents an excellent model to study neural stem cells (NSCs). In order to detect NSCs, we have relied on the fact that adult stem cells divide more slowly than quickly amplifying progenitor cells. By us...
