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

Tissue accumulation of α-ketoadipic (KAA) and α-aminoadipic (AAA) acids is the biochemical hallmark of α-ketoadipic aciduria. This inborn error of metabolism is currently considered a biochemical phenotype with uncertain clinical significance. Considering that KAA and AAA are structurally similar to α-ketoglutarate and glutamate, respectively, we investigated the in vitro effects of these compounds on glutamatergic neurotransmission in the brain of adolescent rats. Bioenergetics and redox homeostasis were also investigated because they represent fundamental systems for brain development and functioning. We first observed that AAA significantly decreased glutamate uptake, whereas glutamate dehydrogenase activity was markedly inhibited by KAA in a competitive fashion. In addition, AAA and more markedly KAA induced generation of reactive oxygen and nitrogen species (increase of 2',7'-dichloroflurescein (DCFH) oxidation and nitrite/nitrate levels), lipid peroxidation (increase of malondialdehyde concentrations), and protein oxidation (increase of carbonyl formation and decrease of sulfhydryl content), besides decreasing the antioxidant defenses (reduced glutathione (GSH)) and aconitase activity. Furthermore, KAA-induced lipid peroxidation and GSH decrease were prevented by the antioxidants α-tocopherol, melatonin, and resveratrol, suggesting the involvement of reactive species in these effects. Noteworthy, the classical inhibitor of NMDA glutamate receptors MK-801 was not able to prevent KAA-induced and AAA-induced oxidative stress, determined by DCFH oxidation and GSH levels, making unlikely a secondary induction of oxidative stress through overstimulation of glutamate receptors. In contrast, KAA and AAA did not significantly change brain bioenergetic parameters. We speculate that disturbance of glutamatergic neurotransmission and redox homeostasis by KAA and AAA may play a role in those cases of α-ketoadipic aciduria that display neurological symptoms.
