Characterization of norovirus RNA replicase for in vitro amplification of RNA.

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
backgroundThe isothermal amplification of RNA in vitro has been used for the study of in vitro evolution of RNA. Although Qβ replicase has been traditionally used as an enzyme for this purpose, we planned to use norovirus replicase (NV3D(pol)) due to its structural simplicity in the scope of in vitro autonomous evolution of the protein. Characteristics of the enzyme NV3D(pol) in vitro were re-evaluated in this context.
resultsNV3D(pol), synthesized by using a cell-free translation system, represented the activities which were reported in the previous several studies and the reports were not fully consistent each other. The efficiency of the initiation of replication was dependent on the 3'-terminal structure of single-stranded RNA template, and especially, NV3D(pol) preferred a self-priming small stem-loop. In the non-self-priming and primer-independent replication reaction, the presence of -CCC residues at the 3'-terminus increased the initiation efficiency and we demonstrated the one-pot isothermal RNA (even dsRNA) amplification by 16-fold. NV3D(pol) also showed a weak activity of elongation-reaction from a long primer. Based on these results, we present a scheme of the primer-independent isothermal amplification of RNA with NV3D(pol) in vitro.
conclusionsNV3D(pol) can be used as an RNA replicase in in vitro RNA + protein evolution with the RNA of special terminal sequences.
