Seventeen saccharides were tested for their ability to bind to the trap lectins of three species of nematode-trapping fungi and prevent nematode capture. The lectin of Arthrobotrys conoides was found to be inhibited by alpha-d-glucose/d-mannose and similar saccharides. The lectins of Monacrosporium eudermatum and Monacrosporium rutgeriensis were inhibited by alpha-l-fucose and 2-deoxy-d-glucose...

Lyoluminescence, the radiation induced light emission during the dissolution of irradiated solid substances like alkali halides, saccharides, amino acids etc. was proposed as a method of dosimetry. I t is established that lyoluminescence is a consequence of a reaction of radicals from radiolysis wi th oxygen dissolved in the solvent. The role of oxygen in the lyoluminescence of saccharides has ...

While developing a combination of capillary electrochromatography (CEC) with tandem mass spectrometry (MS) for the benefit of characterizing complex oligosaccharide mixtures, we needed highly efficient CEC columns operating in an "MS-friendly" mode. We demonstrate here novel types of polar, monolithic CEC columns that separate effectively complex mixtures of saccharides with the use of mobile p...

The Carbohydrate Structure Databases (CSDBs, http://csdb.glycoscience.ru) store structural, bibliographic, taxonomic, NMR spectroscopic, and other data on natural carbohydrates and their derivatives published in the scientific literature. The CSDB project was launched in 2005 for bacterial saccharides (as BCSDB). Currently, it includes two parts, the Bacterial CSDB and the Plant&Fungal CSDB. In...

A method was developed for the synthesis of molecularly imprinted Au nanoparticle (NP) composites on electrodes by electrochemical means. The resulting composites include specific recognition sites for mono- or disaccharides. The method is based on the formation of a boronate complex between the respective saccharide and the boronic acid ligands associated with the Au NPs. The electropolymeriza...

A mixture of glycosaminoglycan (GAG) chains from a plasma proteoglycan bikunin was fractionated using native, continuous-elution polyacrylamide gel electrophoresis, and the resulting fractions were analyzed by electrospray ionization Fourier transform mass spectrometry (ESI FTMS). Molecular mass analysis of the intact GAG afforded information about the length and composition of GAG chains in th...
