Protective Effect of Low Dose of Methamphetamine on The Amount of Extracellular Glutamine in Primary Fetal Human Astrocytes Induced by Amyloid Beta.

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
Objective: Change in astrocytes is one of the first pathological symptoms of Alzheimer's disease (AD). Understanding the signaling pathways in astrocytes can be a great help in treating of AD. This study aimed to investigate signaling pathway relations between low dose of methamphetamine (METH), the apoptosis, cell cycle, and glutamine (Gln) pathways in the activated astrocyte. Materials and Methods: In this experimental study, the activated astrocyte cells were exposed to a low dose of METH (12.5 μM) which was determined by Thiazolyl blue tetrazolium bromide (MTT) method. The groups were: group 1 cells with Aβ, group 2 cells with METH, group 3 cells with METH after 24 hours of adding Aβ (Aβ+METH, treated group), group 4 cells with Aβ after 24 hours of adding METH (METH+Aβ, prevention group), and group 5 as the control. The Gln was assayed by high-performance liquid chromatography (HPLC), and also the apoptosis, and cell cycle and Results: The amount of Gln was increased, and the value of late and early apoptosis was reduced in the treatment groups, and necrosis is decreased in the prevention group (group 4 compared to group 1). Moreover, it was revealed through cell cycle analysis that G2 in group 4 was reduced compared to group 1 and the expression of Conclusion: These findings suggest that perhaps a non-toxic dosage of METH (low dose) can reduce the amount of apoptosis and
