Interaction mechanism of Trp-Arg dipeptide with calf thymus DNA.
Article in Journal of fluorescence, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The interaction between Trp-Arg dipetide (WR) and calf thymus DNA (ctDNA) in pH 7.4 Tris-HCl buffer was investigated by multi-spectroscopic techniques and molecular modeling. The fluorescence spectroscopy and UV absorption spectroscopy indicated that WR interacted with ctDNA in a minor groove binding mode and the binding constant was 4.1 × 10(3). The ionic strength effect and single-stranded DNA (ssDNA) quenching effect further verified the minor groove binding mode. Circular dichroism spectroscopy (CD) was employed to measure the conformation change of ctDNA in the presence of WR. The molecular modeling results illustrated that electrostatic interaction and groove binding coexisted between them and the hydrogen bond and Van der Waals were main acting forces. All the above methods can be widely used to investigate the interaction of peptide with nucleic acids, which contributes to design the structure of new and efficient drugs.
