Fluoro-Jade B histofluorescence staining detects dentate granule cell death after repeated five-minute transient global cerebral ischemia.

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
Transient global cerebral ischemia (tGCI)-induced neuronal damage is variable according to its duration and degree. There are many studies on the damage or death of pyramidal cells of the hippocampus proper (CA1-3) in rodent models of tGCI. However, studies on the death of granule cells in the hippocampal dentate gyrus (DG) following tGCI have not yet been addressed. In this study, we examined the damage/death of granule cells in the gerbil DG at 5 days after various durations (5, 10, and 15 min) of single tGCI and repeated tGCI (two 5-min tGCI with 1-h interval) using cresyl violet staining, NeuN immunohistochemistry and Fluoro-Jade B (F-J B) histofluorescence staining. Neuronal death was observed only in the polymorphic layer in all single tGCI-operated groups. However, in the repeated tGCI-operated group, massive neuronal death was observed in the granule cell layer as well as in the polymorphic layer by using F-J B histofluorescence staining. In addition, microgliosis in the DG was significantly increased in the repeated tGCI-operated group compared to the 15-min tGCI-operated group. Taken together, these findings indicate that repeated brief tGCI causes granule cell death in the DG which could not occur by a longer duration of single tGCI.
