Acetylcholinesterase and heat shock protein 70 response in larval brain tissue of Lymantria dispar L. (Lepidoptera, Limantriidae) upon chronic exposure to benzo(a)pyrene.
Article in Environmental science and pollution research international, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
The effects of different concentrations of benzo(a)pyrene (BaP) (2, 10, 20, 100, 200, and 2000 ng/g dry food weight) on the activity of acetylcholinesterase (AChE) and concentration of heat-shock protein 70 (hsp70) in fifth instar Lymantria dispar brain tissue were investigated. Inhibition of AChE is a general effect biomarker at the individual level. We observed the most efficient inhibition of this enzyme at medium and high BaP concentrations (20, 100, 200, and 2000 ng/g dry food weight). Western blot analysis revealed the presence of two hsp 70 isoforms, with changed amounts depending on the BaP concentration. A fluctuating response in hsp70 concentration to ingested BaP was observed: with decreased levels in the groups fed 2 and 100 ng BaP/g dry food weight, but increased concentrations in the groups given 10 and 2000 ng/g dry food weight. Even though we detected changes in AChE activity and hsp70 concentration in L. dispar brain tissue upon exposure to different BaP concentrations, we cannot characterize them as sensitive and reliable biomarkers for this xenobiotic in L. dispar caterpillars.
