With contrasting observations on the effects of beta-catenin on hematopoietic stem cells (HSCs), the precise role of Wnt/beta-catenin signals on HSC regulation remains unclear. Here, we show a distinct mode of Wnt/beta-catenin signal that can regulate HSCs in a stroma-dependent manner. Stabilization of beta-catenin in the bone marrow stromal cells promoted(More)
This study was carried out to examine the action mechanism of Chamaecyparis obtusa oil (CO) on hair growth in C57BL/6 mice. For alkaline phosphatase (ALP) and γ-glutamyl transpeptidase (γ-GT) activities in the skin tissue, at week 4, the 3% minoxidil (MXD) and 3% CO treatment groups showed an ALP activity that was significantly higher by 85% (p < 0.001) and(More)
A high performance KIER TYPE CYBAGFILTER that combines a fabric filtration and centrifugal dust removal technologies was developed to maintain high performance of the existing bag filter. Based on the performance results obtained from a pilot-scale test unit and fluid dynamics computer simulation, a test CYBAGFILTER of 18,000m3/hr capacity was installed in(More)
Using immunochemical and immunohistochemical methods, the binding site ofAnguilla anguilla agglutinin (AAA) was characterized and compared with the related fucose-specific lectin fromUlex europaeus (UEA-I). In solid-phase enzyme-linked immunoassays, the two lectins recognized Fucα1-2Galβ-HSA. AAA additionally cross-reacted with neoglycolipids bearing(More)
