1 · What the graph read from it

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.

2 · The registry

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

To investigate possible protective effects of pyrroloquinoline quinone (PQQ) on the rat cortex with glutamate injection and to understand the mechanisms linking the in vivo neuroprotection of PQQ. Adult Sprague-Dawley rats received glutamate injection into the rat cortex. Terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling assay was performed to observe influences of co-treatment with PQQ (simultaneous injection with PQQ and glutamate) on neural cell apoptosis in the rat cortex. The production of reactive oxygen species (ROS) in the rat cortex was detected by flow cytometry using 2',7'-dichlorofluorescin diacetate labeling, and the activity of superoxide dismutase, glutathione and malondialdehyde was respectively determined. Real time quantitative RT-PCR and Western blot were applied to measure the mRNA and protein expressions of Nrf1, Nrf2, HO-1 and GCLC in the rat cortex. Western blot was used to detect the phosphorylation of Akt and GSK3β in the rat cortex. Co-treatment with PQQ protected neural cells in the rat cortex from glutamate-induced apoptosis. PQQ decreased the ROS production induced by glutamate injection. PQQ increased the mRNA and protein expressions of Nrf2, HO-1 and GCLC and the phosphorylation of Akt and GSK3β in the cortex of glutamate-injected rats. PQQ could produce neuroprotective effects on the rat cortex. The antioxidant properties of PQQ and PQQ-induced activation of Akt/GSK3β signal pathway might be responsible for the in vivo neuroprotection of PQQ.
