1 · What the graph read from it

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.

2 · The registry

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 use of nucleic acids as potential therapeutic tools, sensors, or biomaterials, among other applications, has dramatically increased. Among these, RNA aptamers are of interest due to an innate high specificity toward their cognate targets, which include small molecules, proteins, ions, or cells. In this work, we took advantage of the ability that 8-oxo-7,8-dihydroguanine (8-oxoG) has to participate in unique H-bonding interactions, and probed its use to increase/control the selectivity/affinity of aptamers of RNA and DNA. The chosen model is a 23-nt long RNA (Neo61/Neo1-5'-GGA CUG GGC GAG AAG UUU AGU CC) strand that folds into a pentaloop hairpin with a stretch of three G·U Wobble pairs within the stem, which is known to have affinity toward various aminoglycosides. 8-OxoG was incorporated at positions G6, G7, G10, G12, or G15, within aptamers composed of RNA, DNA, or 2'-OMe modified RNA. Their recognition was tested toward 9 small molecule targets with aminoglycoside (x8) or antibiotic (x1) backbones, and their affinities were measured via circular dichroism (CD). Isothermal titration calorimetry (ITC) was used to corroborate the use of CD as a reliable technique. It was determined that incorporation of 8-oxodG at position-12 within DNA (
