    Notes: Measurement of progesterone concentration in blubber was developed as a method to detect pregnancy in minke whales. Progesterone was extracted and quantified from blubber samples of minke whale carcasses by radioimmunoassay. Results showed a highly significant difference (almost 60-fold) between blubber progesterone concentrations of anatomically determined pregnant females versus non-pregnant female or male carcasses. The results of the study suggest that the blubber progesterone concentrations might be used to determine pregnancy status in free-ranging whales.

    Notes: Lipopolysaccharides extracted from the isolated outer membrane fractions of Bradyrhizobium sp. 32H1 bacteroids, grown in maintenance and induction media supplemented with either arabinose or arabinose and succinate, were free of extracellular polysaccharide and lacked any detectable pyruvic and uronic acids. The neutral sugars l-rhamnose, d-mannose, d-glucose and l-glycero-d-manno-heptose were present in the bacteroids grown in all 3 media. The amino sugar 2-acetamido-2,6-dideoxy-d-glucose was detected in the lipopolysaccharide isolated from the bacteroids grown in both the maintenance and induction media supplemented with arabinose only, but not succinate. Appreciable amount of both 2-acetamido-2-deoxy-d-glucose and 2-acetamido-2-deoxy-d-galactose were found in the lipopolysaccharide of the bacteroids grown in arabinose-supplemented induction media.

    Notes: Application of pyrolysis-desorption chemical ionization mass spectrometry (Py-DCI-MS) is demonstrated for the structural characterization of the native O-specific antigen of Yersinia ruckeri. Under proper pyrolytic and chemical ionization conditions this antigenic polysaccharide yields anhydrohexosamine fragments which facilitate identification of the trimeric repeating unit sequence. Tandem mass spectrometric analyses of the trimeric repeating unit fragments provided additional evidence for the proposed structure and permitted rationalization of the observed fragment ions. Furthermore, Py-DCI-MS of smaller hexosamine subunits isolated during off-line pyrolysis experiments showed fragmentation characteristics almost identical with those observed in the mass spectra of the whole antigen, hence confirming the stability of the pyrolysis fragments.

    Notes: The analysis of underivatized oligosaccharides arising from mild acid hydrolysis of endotoxins from Yersinia ruckeri serotype 02 was achieved using on-line capillary zone electrophoresis-electrospray mass spectrometry (CZE-ESMS). This technique provided unparalleled resolution of the differnt glycans obtained from purified fractions of the native endotoxins or from hydrolysis of lipopolysaccharides from Y. ruckeri. Electrophoretic conditions enabling the separation of anionic and cationic analytes were developed to determine possible sites of heterogeneity on either the core or the O-chain glycans. Structural characterization of underivatized oligosaccharides identified in the ion electropherograms was achieved using tandem mass spectrometry under lowcollision energy conditionsNRCC 39726..
