42 to 3.72 cV) for the distinct morphologies. The blue and green PI. emissions observed in these crystals were ascribed to the intermediary energy levels arising from the distortions on the [MoO4] clusters clue to intrinsic defects in the lattice of anisotropic/isotropic crystals.”
“An ongoing program to continuously collect time- and size-resolved aerosol samples from ambient air at Summit Station, Greenland (72.6 N, 38.5 W) is building a long-term data base to both record individual transport events GSI-IX in vitro and provide long-term
temporal context for past and future intensive studies at the site. As a “first look” at this data set, analysis of samples collected from summer 2005 to spring 2006 demonstrates the utility of continuous sampling to characterize air masses over the ice learn more pack, document
individual aerosol transport events, and develop a long-term record. Seven source-related aerosol types were identified in this analysis: Asian dust, Saharan dust, industrial combustion, marine with combustion tracers, fresh coarse volcanic tephra, and aged volcanic plume with fine tephra and sulfate, and the well-mixed background “Arctic haze”. The Saharan dust is a new discovery; the other types are consistent with those reported from previous work using snow pits and intermittent ambient air sampling during intensive study campaigns. Continuous sampling complements the fundamental characterization of Greenland aerosols developed in intensive field programs by providing a year-round record of aerosol size and composition at all temporal scales relevant to ice core analysis, ranging from individual deposition events and seasonal cycles, to a record of inter-annual variability of aerosols from both natural and anthropogenic sources.

“Tryptophyllins buy BTSA1 are a group of small (4-14 amino acids),
heterogenous peptides, mostly from the skins of hylid frogs from the genera, Phyllomedusa and Litoria. To date, more than forty TPHs have been discovered in species from these two genera. Here, we describe the identification of a novel tryptophyllin type 3 peptide, PhT-3, from the extracts of skin of the orange-legged monkey frog, Phyllomedusa hypochondrialis, and molecular cloning of its precursor-encoding cDNA from a cDNA library constructed from the same skin sample. Full primary structural characterization was achieved using a combination of direct Edman degradation, mass spectrometry and deduction from cloned skin-derived cDNA. The open-reading frame of the precursor cDNA was found to consist of 63 amino acid residues. The mature peptide arising from this precursor contains a post-translationally modified N-terminal pyroglutamate (pGlu) residue, formed from acid-mediated cyclization of an N-terminal Gln (Q) residue, and with the structure: pGlu-Asp-Lys-Pro-Phe-Trp-Pro-Pro-Pro-Ile-Tyr-Pro-Met.
