S-oxiracetam Facilitates Cognitive Restoration after Ischemic Stroke by Activating α7nAChR and the PI3K-Mediated Pathway.
Article in Neurochemical research, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
S-oxiracetam (S-ORC), a nootropic drug, was used to protect against ischemic stroke by lessening the blood brain barrier dysfunction and inhibiting neuronal apoptosis. However, the potential effects of S-ORC in the recovery of cognitive functions after ischemic stroke and the underlying mechanisms remains unclear. In this study, middle cerebral artery occlusion/reperfusion (MCAO/R) in rats was used as the animal model. By using Y-maze test, Morris water maze, triphenyl tetrazolium chloride (TTC) staining, terminal deoxynucleotidyl transferase-mediated 2'-deoxyuridine 5'-triphosphate (dUTp) nick end labeling (TUNEL) assay, hematoxylin and eosin, immunohistochemical staining and western blot to evaluate the protective effect of S-ORC on cognitive recovery, we were able to confirm that S-ORC ameliorated spatial learning impairment, tissue loss, and hippocampal neuronal apoptosis and injury induced by MCAO/R in rats. These cognitive effects were achieved by restoring the normal function of synaptophysin and increasing PSD95 expression in the hippocampus. Furthermore, we found that methyllycaconitine, the antagonist of α7 nicotinic acetylcholine receptor (α7nAChR), and LY294002, the inhibitor of phosphoinositide 3-kinase (PI3K), were able to block the cognitive effects of S-ORC after MCAO/R in rats. In conclusion, α7nAChR and PI3K are key molecules that mediated the signaling pathway leading to S-ORC-induced cognitive restoration after MCAO/R.
