Transition-metal tetravalent manganese ions (Mn4+ ) as luminescence center of red phosphors have drawn much attention owing to their broad-band absorption extended from UV to blue regions and narrow red-emissive band. In the present work, a series of Mn4+ -doped BaGeF6 red phosphors were obtained via hydrothermal method. X-ray powder diffraction, energy-dispersive X-ray spectrometer, scanning electron microscope, and photoluminescence spectra were employed to determine the crystal structure, composition, morphology, and photoluminescence properties of all samples...

The abnormal expression of microRNAs (miRNAs) in colorectal cancer (CRC) progression has been widely investigated. It was reported that the same hairpin RNA structure could generate mature products from each strand, termed 5p and 3p, which binds different target mRNAs. Here, we explored the expression, functions, and mechanisms of miR-514b-3p and miR-514b-5p in CRC cells and tissues. We found that miR-514b-3p was significantly down-regulated in CRC samples, and the ratio of miR-514b-3p/miR-514b-5p increased from advanced CRC, early CRC to matched normal colorectal tissues...

Endophilin A1 is a member of the endophilin A family and is primarily expressed in the central nervous system. Endophilin A1 can mediate neuronal excitability by regulating neuronal synaptic plasticity, which indicates that the protein may be involved in epilepsy. However, to date, its role in epilepsy remains unclear. To explore the role of endophilin A1 in epilepsy, we aimed to investigate the expression patterns of endophilin A1 in patients with temporal lobe epilepsy (TLE) and in a pentylenetetrazole (PTZ)-kindled epileptic mouse model and to conduct behavioral and electrophysiological analyses after lentivirus-mediated knockdown of endophilin A1 in the hippocampus of epileptic mice...

This work describes three different strategies to structurally rearrange one 3-alkylidene-2H-1,2-oxazine molecule into three distinct heterocycles using HOTf, propiolic acid, and silica gel, respectively. The mechanisms of these rearrangement reactions involve three independent routes, including (i) Brønsted acid catalysis, (ii) a synergetic action of Brønsted acids and anions, (iii) a surface-directed chemoselectivity.

Colorectal cancer includes an invasive stem-like/mesenchymal subtype, but its genetic drivers, functional, and clinical relevance are uncharacterized. Here we report the definition of an altered miRNA signature defining this subtype that includes a major genomic loss of miR-508. Mechanistic investigations showed that this miRNA affected the expression of cadherin CDH1 and the transcription factors ZEB1, SALL4, and BMI1. Loss of miR-508 in colorectal cancer was associated with upregulation of the novel hypoxia-induced long noncoding RNA AK000053...

The cycloadditions of molecular dioxygen with neutral π-bond motifs rely heavily on singlet-state (1)O2, whereas ground state (3)O2 is chemically inactive. Here we report novel [3 + 2]-annulations among ground-state (3)O2 (1 bar), allenes, and nitrosoarenes at low temperatures, efficiently yielding dioxygen-containing oxacycles. With less hindered 1-arylallene derivatives, these dioxygen species undergo skeletal rearrangement to 3-hydroxy-1-ketonyl-2-imine oxides. These cycloadditions represent valuable one-pot O,N,O-trifunctionalizations of allenes...

A facile way was developed to fabricate yolk-shell composites with tunable Cu cores encapsulated within hollow carbon spheres (Cu@C) with an average diameter about 210 nm and cavity size about 80 nm. During pyrolysis, the confined nanospace of hollow cavity ensures that the nucleation-and-growth process of Cu nanocrystals take place exclusively inside the cavities. The size of Cu cores can be easily tuned from 30 to 55 nm by varying the copper salt concentration. By deliberately creating shell porosity through KOH chemical activation, at an optimized KOH/HCS mass ratio of 1/4, the catalytic performance for the oxidative carbonylation of methanol to dimethyl carbonate (DMC) of the activated sample is enhanced remarkably with TOF up to 8...

Nanostructured CoO/NiO/CoNi composites as anode materials for lithium-ion batteries (LIBs) have been successfully prepared by a facile, straightforward, and large-scale dealloying method. The effects of NaOH solution concentration on the structure, morphology and electrochemical performances of the resulting products are studied systematically. These results indicate that the concentration of NaOH solution mainly influences the morphology of the CoO/NiO/CoNi composites. Cyclic voltammetry (CV) and charge-discharge tests have been conducted to assess the lithium storage performances of the CoO/NiO/CoNi anodes obtained from the 5 M NaOH solution...
