Differential Influence of Amyloid-β on the Kinetics of Dopamine Release in the Dorsal and Ventral Striatum of Rats.

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
Dopaminergic dysfunction is a part of Alzheimer's disease pathology. The brain accumulation of amyloid-β of toxic form is a key link of the pathology, which, according to the literature, is also true for dopaminergic dysfunction. An increase in the amyloid-β level in the brain changes the maximum of the evoked dopamine release in the dorsal and ventral parts of the striatum of the experimental animals. Theoretically, this may be due to the change in the intensity of dopamine release from the nerve terminals or its reuptake. However, it has not been studied. To fill this gap, we examined the amyloid-β induced changes in the kinetics of the evoked dopamine release in the dorsal striatum and the nucleus accumbens core and shell. Amyloid-β solution (fragments 25-35) was injected into the ventricular system of the anesthetized male Wistar rats. Before and after injection, electrically evoked dopamine kinetics was registered with fast-scan cyclic voltammetry. The results had shown that the amount of dopamine release decreases in the dorsal striatum and increases in the nucleus accumbens shell. No changes were found in the intensity of dopamine reuptake.
