In bacteria, elongation factor Tu is a translational cofactor that forms ternary complexes with aminoacyl-tRNA (aa-tRNA) and GTP. Binding of a ternary complex to one of four flexible L7/L12 units on the ribosome tethers a charged tRNA in close proximity to the ribosomal A site. Two sequential tests for a match between the aa-tRNA anticodon and the current mRNA codon then follow. Because one elo...

Nanometer films composed of model ternary blend of deuterated polystyrene (dPS), poly(2-vinylpyridine) (PVP) and poly(methyl methacrylate) (PMMA) were studied after spin-coating from a common solvent. Surface undulations and the distribution of phase-separated domains at the surface and in the bulk are closely related as revealed by atomic (AFM) and lateral (LFM) force microscopy. For the first...

An open-tubular capillary chromatography is developed based on tube radial distribution of the ternary mixed carrier solvents of water-hydrophilic/hydrophobic organic under laminar flow conditions. This is called “tube radial distribution chromatography” (TRDC). Fluidic behavior of the polymer compounds, FluoSpheres (1.0 m diameter), was examined by the TRDC system. The ternary mixture of wate...

Poorly water-soluble drugs N-5159, griseofulvin (GFV), glibenclamide (GBM) and nifedipine (NFP) were ground in a dry process with polyvinylpyrrolidone (PVP) and sodium dodecyl sulfate (SDS). Different crystallinity behavior of each drug during grinding was shown in the ternary Drug/PVP/SDS system. However, when each ternary Drug/PVP/SDS ground mixture was added to distilled water, crystalline n...

In the present work, levofloxacin based microemulsion was developed and its usefulness as topical drug carrier system for anti bacterial activity was investigated. Microemulsion was prepared by phase titration method using oleic acid as oil phase, tween-60 as surfactant and isopropyl alcohol as co-surfactant. Five different formulations were formulated with various amount of the oil, water and ...
