Calpain inhibition prevents ethanol-induced alterations in spinal motoneurons.

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
Long-term exposure of ethanol (EtOH) alters the structure and function in brain and spinal cord. The present study addresses the mechanisms of EtOH-induced damaging effects on spinal motoneurons in vitro. Altered morphology and biochemical changes of such damage were demonstrated by in situ Wright staining and DNA ladder assay. EtOH at low to moderate (25-50 mM) concentrations induced damaging effects in the motoneuronal scaffold which involved activation of proteases like μ-calpain and caspase-3. Caspase-8 was seen only at higher (100 mM) EtOH concentration. Further, pretreatment with calpeptin, a potent calpain inhibitor, confirmed the involvement of active proteases in EtOH-induced damage to motoneurons. The lysosomal enzyme cathepsin D was also elevated in the motoneurons by EtOH, and this effect was significantly attenuated by inhibitor treatment. Overall, EtOH exposure rendered spinal motoneurons vulnerable to damage, and calpeptin provided protection, suggesting a critical role of calpain activation in EtOH-induced alterations in spinal motoneurons.
