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

Copper oxide nanoparticles (CuO-NPs) dispersions are known for their high cell toxic potential but contaminating copper ions in such dispersions are a major hurdle in the investigation of specific nanoparticle-mediated toxicity. In order to distinguish between the adverse effects exhibited by CuO-NPs and/or by contaminating ionic copper, the membrane-impermeable copper chelator bathocuproine disulfonate (BCS) was added in a low molar ratio (20% of the total copper applied) in order to chelate the copper ions that had been released extracellularly from the CuO-NPs before or during the incubation. Physicochemical characterization of synthesized CuO-NPs revealed that the presence of this low concentration of BCS did not alter the size or zeta potential of the CuO-NPs. Application of CuO-NPs to C6 glioma cells and primary astrocytes induced a concentration- and temperature-dependent copper accumulation which was accompanied by a severe loss in cell viability. The adverse consequences of the CuO-NP application were not affected by the presence of 20% BCS, while the copper accumulation and cell toxicity observed after application of ionic copper were significantly lowered in the presence of BCS. These results demonstrate that for the experimental conditions applied the adverse consequences of an exposure of cultured glial cells to dispersions of CuO-NPs are mediated by accumulated NPs and not caused by the uptake of contaminating copper ions.
