An immunosuppressant FK506 has been reported to induce osteoblast differentiation in vivo [J. Bone Miner. Res. 15 (2000) 1147]. To study the role of FK506 in osteoblast differentiation, we examined the mRNA expressions of several marker genes (Cbfa1, osteopontin, and alkaline phosphatase) in an osteoblastic cell line: UMR106-6. Results showed that the Cbfa1 (osteoblast specific transcription factor) expression in UMR cells was enhanced by treatment with FK506, promoting osteoblast differentiation. The effect was marked when simultaneous treatment with FK506 and dexamethasone was given to UMR cells comparing with the effects of treatment with each substance alone or non-treatment.

Using femtosecond pulse-pair excitation at 800-nm, delay-time dependent adatom desorption from the Si(111)-7/spl times/7 surface was observed by scanning tunneling microscopy. Trends in the desorption yield and site selectivity were detected as a function of delay time.

The unusual coexistence of two antiferromagnetic (AF) long-range orderings (LRO) in single-crystal NiS2 is investigated through measurements of inelastic neutron scattering, specific heat, uniform magnetic susceptibility, and resistivity. Neutron scattering intensity reveals a honeycomb pattern of the intensity distribution in reciprocal lattice space (continuous-line structure along the Brillouin zone boundaries) in the extended critical temperature region (TN1=39.3K

Summary form only given. In this paper, we demonstrate the experimental evolution of ultra-broad spectra generated by photonic crystal fibers (PCFs) of different lengths, and theoretically analyze the nonlinear process based on our derived nonlinear propagation equation beyond the slowly-varying-envelope approximation (SVEA). The calculated results of the complicated frequency-dependent phase are significantly useful for extremely flexible and accurate active-chirp compensation by a 4-f pulse shaper with a spatial phase modulator for monocycle-pulse generation.
