The localization of vacuolar-type H+-ATPase and carbonic anhydrase II (CA II) in rat incisor enamel organs at maturation was examined by light and electron microscopy. The immunoreactivity for both vacuolar-type H+-ATPase and CA II was intense on the ruffled border of ruffle-ended ameloblasts (RA), but moderate at the distal end of smooth-ended ameloblasts(More)
In next generation mobile communication systems, the traffic distribution is expected to be non-uniform between cells due to diversified traffic sources and large amount of user traffic. The traffic non-uniformity between cells not only makes communication quality non-uniform between cells, but also decreases the system capacity. In this paper, we focus on(More)
An oblique shock wave in a supersonic flow field was measured and visualized using Particle Tracking Velocimetry (PTV). The beginning of the velocity drop at the shock wave was sharper than that detected by general Particle Image Velocimetry (PIV). The location of the shock wave in the obtained velocity vector was in good agreement with that in Schlieren(More)
The mechanism of space flight-induced bone mass loss is unknown. We conducted experiments aboard the Space Shuttle using primary cultured osteoblasts. During flight, quadruplicate cultures were treated with 1 nM of 1alpha,25 dihydroxyvitamin D3 for one day, then fixed with guanidine isothiocyanate solution on board. After return to the Earth, the mRNA(More)
