Effects of Mono-2-ethylhexyl Phthalate on the Neural Transmission of PNs in Drosophila Antennal Lobe.

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 to different types of chemicals is hazardous to human health. Di(2-ethylhexyl) phthalate (DEHP) could exert pleiotropic deleterious effects on nervous systems. Mono(2-ethylhexyl) phthalate (MEHP), as one of the most toxic metabolites of DEHP, may have similar effects on nervous systems. However, no effects of MEHP on neural circuits have been reported. To uncover the regulation of MEHP on neural transmission, the functional changes of neural excitability and synaptic plasticity of projection neurons (PNs) have been assessed. In the current study, we recorded the action potentials (APs), stimulate action potentials (sti-APs), mini excitement postsynaptic current (mEPSC), calcium currents, and sodium currents from PNs of isolated whole brain of Drosophila model utilizing patch clamp recordings. We found that MEHP-300 (at the concentration of 300 μM), but not MHEP-100 (at the concentration of 100 μM), significantly decreased the frequency and amplitude of APs. Besides, the amplitude and anti-amplitude of sti-APs were reduced with the application of MEHP-300. Meanwhile, MEHP-300 reduced the frequency of mEPSC, but not the amplitude. Furthermore, MEHP-300 reduced the peak current densities of sodium and calcium channels. Therefore, our results indicated that MEHP could alter the neural excitability and synaptic plasticity of PNs by inhibiting the ion channels activities, revealing the potential modulation of MEHP on neural transmission of PNs.
