Regge pole analysis of inelastic e - p scattering data

Based on the Regge pole fit to the high energy data on the e-p structure functions the q²-dependence of the Pomeranchuk and A₂ residues is determined in the non-scaling region. A FESR for vW₂ together with knowledge of these Regge residues is employed to confirm the existence of the J = 0 fixed pole in the virtual Compton amplitude.     

Metathesis reactions of pyrazolotriazinones generate dynamic combinatorial libraries

[reaction: see text] Reversible metathesis reactions of pyrazolotriazinones and aliphatic aldehydes or ketones proceed in aqueous, phosphate-buffered media at pH 4 and 40-60 degrees C to generate thermodynamically controlled mixtures of heterocycles.     

Schizophyllans carrying oligosaccharide appendages as potential candidates for cell-targeted antisense carrier

Schizophyllans carrying beta-lactoside and alpha-mannoside appendages were prepared from native schizophyllan through NaIO4 oxidation followed by reductive amination using aminoethyl-beta-lactoside and alpha-mannoside, respectively. The resulting schizophyllans form stable macromolecular complexes with polynucleotides, such as poly(C) and poly(dA). Specific affinity between these macromolecular complexes and saccharide-binding proteins was demonstrated by surface plasmon resonance and agarose gel staining assays. beta-lactoside-appended schizophyllan enhanced an antisense activity in hepatocytes which express lactoside-binding proteins on their cell surfaces.

Specific band observed in VCD predicts the anomeric configuration of carbohydrates

The vibrational circular dichroism (VCD) technique was applied to carbohydrates and produced a glycoside characteristic VCD band, which was named the "glycoside band." It confirmed that this vibration was related to anomeric configurations of carbohydrates in the case of the d-series by means of isotope substitution. This band is defined as a negative, sharp, and intense VCD band at around 1145 cm-1, exhibited by d-sugars with an axial alpha-glycosidic linkage in the 4C1 conformation. As applications of this band, the VCD studies of the maltose-cellobiose mixture and the monitoring of the amyloglucosidase reaction were examined.

Submitochondrial distribution of basic drugs in the isolated perfused lung

To clarify the mechanism by which basic drugs accumulate in the lung mitochondria, the binding selectivity of drugs to different submitochondrial components of the perfused rat lung was examined. The accumulation of basic drugs was the highest in the mitochondrial outer membrane fraction. The drug accumulation in this fraction increased with lipid solubility and was dose-dependent. It appears then that selective binding sites for basic drugs are present in the mitochondrial outer membrane.
