rpoS, a gene that encodes an alternative sigma factor (also known as katF), is critical for the ability of Yersinia enterocolitica grown at 37 degrees C, but not at 26 degrees C, to survive diverse environmental insults such as high temperature, hydrogen peroxide, osmolarity, and low pH. However, a Y. enterocolitica rpoS mutant was not affected in expression of inv or ail, invasion of tissue cu...

The high-pressure liquid chromatographic separation of ail of the known metabolites of vitamin D2 and vitamin D3 found in biological fluids has been achieved. This technique has been successfully applied to the analysis of vitamin D mixtures, purification of vitamin D metabolites, and identification of radioactive peaks. Some theoretical bases for the observed resolutions are suggested. Supplem...

During 5 years of operation COMPTEL has collected data covering the entire sky, with exposures ranging from weeks to months. Full sky maps have already been published using data from the rst 3 years of the mission; the additional information now a v ail-able represent a signiicant addition to the COMP-TEL data base and allows us to consolidate previous results. We present the most recent whole-...
