Glutamate Toxicity to Differentiated Neuroblastoma N2a Cells Is Prevented by the Sesquiterpene Lactone Achillolide A and the Flavonoid 3,5,4'-Trihydroxy-6,7,3'-Trimethoxyflavone from Achillea fragrantissima.
Article in Journal of molecular neuroscience : MN, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Glutamate toxicity is a major contributor to the pathophysiology of numerous neurodegenerative diseases including amyotrophic lateral sclerosis and Alzheimer's disease. Therefore, protecting neuronal cells against glutamate-induced cytotoxicity might be an effective approach for the treatment of these diseases. We have previously purified from the medicinal plant Achillea fragrantissima two bioactive compounds which were not studied before: the sesquiterpene lactone achillolide A and the flavonoid 3,5,4'-trihydroxy-6,7,3'-trimethoxyflavone (TTF). We have shown that these compounds protect astrocytes from oxidative stress-induced cell death and inhibit microglial activation. The current study examined for the first time their effects on differentiated mouse neuroblastoma N2a cells and on glutamate toxicity. We have found that, although these compounds belong to different chemical families, they protect neuronal cells from glutamate toxicity. We further demonstrate that this protective effect might be, at least partially, due to inhibitory effects of these compounds on the levels of reactive oxygen species produced following treatment with glutamate.
