[source] Reactions under Autogenic Pressure at Elevated Temperature (RAPET) of Various Alkoxides: Formation of Metals/Metal Oxides-Carbon Core-Shell StructuresCHEMISTRY - A EUROPEAN JOURNAL, Issue 18 2004Swati V. Pol Abstract The RAPET reaction at 700,°C, of different alkoxides (Ti, V, and Si) led to three different nanocomposites. Carbon is the element common to all three structures. Carbon was found as the core in the decomposition of TEOS, as the shell in the decomposition of VO(OEt)3 and embedded in, or mixed completely with, TiO2 in the decomposition of Ti(OiPr)4. This novel method using only metallic alkoxide precursor, in the absence of catalyst, leads in a one-step process to core-shell structures. [source] Analysis of a Leptospira interrogans locus containing DNA replication genes and a new IS, IS1502FEMS MICROBIOLOGY LETTERS, Issue 2 2002R.L. Zuerner Abstract A region of the Leptospira interrogans serovar pomona genome encoding DNA replication genes was characterized. This region, designated the ppa-ntrC locus, includes 19 open reading frames and a new insertion sequence, IS1502. Although this locus resembles replication origins from many eubacteria, it lacks several genes common to homologous loci. Some replication-related genes were previously located near rrf, and may have been moved to that location by homologous recombination between short sequence elements common to both loci. Further analysis showed that the ppa-ntrC region has undergone substantial change during spirochete evolution. Transcription analysis using RT-PCR revealed uniquely organized polycistronic mRNAs in the ppa-ntrC locus. The dnaN and recF intergenic region of serovar pomona was different from the homologous sites of 41 L. interrogans serovars by the presence of IS1502. The distribution of IS1502 throughout pathogenic Leptospira species varies. This result suggests that IS1502 may have been recently introduced into Leptospira. [source] ,Mass defect' tags for biomolecular mass spectrometryJOURNAL OF MASS SPECTROMETRY (INCORP BIOLOGICAL MASS SPECTROMETRY), Issue 8 2003Michael P. Hall Abstract We present a new class of ,mass defect' tags with utility in biomolecular mass spectrometry. These tags, incorporating element(s) with atomic numbers between 17 (Cl) and 77 (Ir), have a substantially different nuclear binding energy (mass defect) from the elements common to biomolecules. This mass defect yields a readily resolvable mass difference between tagged and untagged species in high-resolution mass spectrometers. We present the use of a subset of these tags in a new protein sequencing application. This sequencing technique has advantages over existing mass spectral protein identification methodologies: intact proteins are quickly sequenced and unambiguously identified using only an inexpensive, robust mass spectrometer. We discuss the potential broader utility of these tags for the sequencing of other biomolecules, differential display applications and combinatorial methods. Copyright © 2003 John Wiley & Sons, Ltd.
