Vasopressin (VP)-like immunoreactivity has long been known in the hydra nervous system, but has not yet been structurally identified. In this study, using HPLC fractionation and an immunological assay, we have purified two peptides, FPQSFLPRGamide and SFLPRGamide, from Hydra magnipapillata. Both the peptides shared the same C-terminal structure, -PRGamide, with Arg-VP. The nonapeptide proved to...

Gold nanoparticles (npAu, 5 nm diameter) stabilized by hexanethiol and dodecanethiol do not exhibit in THF upon laser flash excitation (355 nm) any detectable transient in the microsecond timescale. However, using octadecanethiol as npAu ligand, a weak signal attributed to THF solvated electrons was observed after excitation 355 nm. In contrast, irrespective of the alkyl length of the thiol lig...

A Doppler lidar system based on the molecular double-edge technique is described. The system is mounted in a modified van to permit deployment in field operations. The lidar operates with a tripled Nd:YAG laser at 355 nm, a 45-cm-aperture telescope, and a matching azimuth-over-elevation scanner to permit full sky access. Validated atmospheric wind profiles were measured from 1.8 to 35 km with a...

A new continuous retinoblastoma cell line (Rb 355-7) derived from a nonfamilial unilaterally-affected child was studied morphologically and with regard to HLA expression. The tumor was compared with two older and widely studied cell lines, the Y-79 and WERI-Rbl strains. The Rb 355-7 line grew in tissue culture in clusters and chains. Its doubling time was calculated to be 4.4 days. In contrast ...
