In vertebrate retina, melatonin regulates various physiological functions. In this work we investigated the mechanisms underlying melatonin-induced potentiation of glycine currents in rat retinal ganglion cells (RGCs). Immunofluorescence double labelling showed that rat RGCs were solely immunoreactive to melatonin MT 2 receptors. Melatonin potentiated glycine currents of RGCs, which was reversed by the MT 2 receptor antagonist 4-P-PDOT.
This paper investigates the degradation of chlorobenzene by dielectric barrier discharge (DBD) coupled with MnO x /γ-Al 2 O 3 catalysts. MnO x /γ-Al 2 O 3 catalysts were prepared using the impregnation method and were characterized in detail by N 2 adsorption/desorption, x-ray diffraction and x-ray photoelectron spectroscopy. Compared with the single DBD reactor, the coupled reactor has a better performance on the removal rate of chlorobenzene, the selectivity of CO x , and the inhibition of ozone production, especially at low discharge voltages. The degradation rate of chlorobenzene and selectivity of CO x can reach 96.3% and 53.0%, respectively, at the specific energy density of 1350 J l -1 . Moreover, the ozone concentration produced by the discharge is significantly reduced because the MnO x /Al 2 O 3 catalysts contribute to the decomposition of ozone to form oxygen atoms for the oxidation of chlorobenzene. In addition, based on analysis of the byproducts, the decomposition mechanism of chlorobenzene in the coupled reactor is also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
