The performance of the current preparative-scale isoelectric trapping systems is limited by the serial arrangement of the separation compartments. A new system has been developed that achieves trapping by recursive electrophoresis in a compartmentalized system (T-RECS). T-RECS features (i) parallel-connected

One-dimensional (1D) helical organic nanostructures were synthesized by a modified vapor-solid (VS) process, called the vaporization-condensation-recrystallization (VCR) process. The conventional solution-phase synthetic methods generally mediate self-assemblies of repeating unit molecules. To provide enough intermolecular interaction forces among the unit molecules

In mouse fibroblasts stimulated from quiescence into proliferation by serum the induction of expression of the c-myc proto-oncogene is strongly stimulated by 3-methoxybenzamide. Similar superinduction effects are seen with related compounds such as 3-aminobenzamide and the acid analogues, 3-anisic acid

The aerobic metabolism of 3-aminobenzoate by bacteria was studied. Bacterial strains degrading 3-aminobenzoate were obtained by enrichment with 3-aminobenzoate (strain Ia3) or 5-aminosalicylate (strains BN9 and 5AS1). During growth with 3-aminobenzoate, strain Ia3 and strain 5AS1 transiently accumulated 5-aminosalicylate in
