NMR investigation of the electrostatic effect in binding of a neuropeptide, achatin-I, to phosphatidylcholine bilayers
Article Abstract:
The electrostatic effect of the N-terminal N[H.sub.3.sup.+] on the binding of a neuropeptide, achatin-I, to zwitterionic phosphatidylcholine (PC) bilayers is investigated. The results have shown that the ionization state of the N-terminal N[H.sub.3.sup.+] has controlled the electrostatic effect of the side chain [beta]-C[O.sub.2.sup.-] in Asp4 floats achatin-I on the PC membrane surface and the binding equilibrium.

Time-resolved investigations of singlet oxygen luminescence in water, in phosphatidylcholine, and in aqueous suspensions of phosphatidylcholine or HT29 cells
Article Abstract:
Singlet oxygen is generated by energy transfer from the photoexcited sensitizer, photofrin or 9-acetoxy-2,7,12,17-tetrakis-(beta-methoxyenthyl)-porphycene. The findings indicate that the measured luminescence decay time of singlet oxygen is shorter than in the case of photofrin but longer than in water.

ZnO well-faceted fibers with periodic junctions
Article Abstract:
ZnO well-faceted microfibers with periodic junctions were prepared by an evaporation and deposition process. A study on the photoluminescence (PL) and PL microscopy fibers showed that it could serve as microscale waveguides and emit enhanced green lights at the junctions under UV excitation.
