Endothelin-1 mediated vasoconstriction leads to memory impairment and synaptic dysfunction.
Article in Scientific reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Cerebrovascular lesions seen as white matter hyperintensity in MRI of elderly population caused due to micro-infracts and micro-bleeds contributes to vascular dementia. Such vascular insult caused by impairment in blood flow to specific area in brain involving small vessels can gradually worsen the pathology leading to cognitive deficits. In the present study we developed a transient model of vaso-constriction to study the impact of such pathology by bilateral injection of ET-1 (Endothelin-1; a 21 amino acid vasoconstricting peptide) into lateral ventricles of C57 mice. The impediment in cerebral blood flow decreased CD31 expression in endothelial cells lining the blood vessels around the hippocampal region, leading to memory deficits after 7 days. Activity dependent protein translation, critical for synaptic plasticity was absent in synaptoneurosomes prepared from hippocampal tissue. Further, Akt1- mTOR signaling cascade was downregulated indicating the possible cause for loss of activity dependent protein translation. However, these effects were reversed after 30 days indicating the ephemeral nature of deficits following a single vascular insult. Present study demonstrates that vasoconstriction leading to memory deficit and decline in activity dependent protein translation in hippocampus as a potential molecular mechanism impacting synaptic plasticity.
