Microglia and Astrocytes in the Lateral Vestibular Nuclei of Mice after Vestibular Stimulation.
Article in Acta naturae. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BALB/C mice were subjected to vestibular loading (rotation in individual containers at a speed of 80 rpm) for 8 h. As a result of this loading, the animals exhibited a decrease in horizontal and vertical locomotor activity, which returned to the control levels after 5 days. An immunohistochemical study of mi croglia and astrocytes in the lateral vestibular nuclei (LVN) revealed elevated levels of protein markers for astrocytes (GFAP) and microglia (Aif1) one hour and 5 days after the stimulation. These changes were indic ative of a gradual development of neuroinflammation in the LVN, which lasted for at least 5 days. Microglia, which appeared in branched shape in control animals, acquired an amoeboid reactive shape after vestibu lar loading. Moreover, expression of the genes coding for these proteins remained at the control level one hour after the stimulation and showed a reduction after 5 days. It is assumed that such a decrease helps re solve the neuroinflammation, preventing it from becoming chronic. Neuroinflammation in the acute phase is known to play a protective role and is required for plastic rearrangements of neuronal and glial networks. Transition to the chronic phase results in neuronal damage. The results of this study would allow one to de termine the period when it is reasonable to use anti-inflammatory therapy to mitigate damage. The applied model of vestibular stimulation allows one to solve problems when studying plastic rearrangements in the brain structures of the vestibular system under high-intensity sensory load.
