Afterglow Copper(I) Iodine Cluster Scintillator.

Copper(I) iodine clusters have drawn intense attention due to their advantageous photophysical properties, such as a high luminescence efficiency, large Stokes shift, and tunable luminescence lifetimes. In this work, a copper(I) iodine cluster (CuI-CHCN) was synthesized, which exhibits unique afterglow emission, ultrahigh quantum yield (90.1 % in solid state) and aggregation-induced emission (AIE) behavior.

Tunable covalent benzo-heterocyclic rings constructed using two-dimensional conjugated polymers for visible-light-driven water splitting.

Developing highly efficient, stable, and cost-effective two-dimensional (2D) conjugated polymers (CPs) for overall water splitting (OWS) is critical for producing clean and renewable hydrogen energy, yet it remains a great challenge. Here, we designed eight 2D CPs through the topological assembly of diacetylene and benzene-derived molecular linkers that can offer active sites for hydrogen and oxygen evolution reactions, and explored their structural, electronic, optical, and photocatalytic OWS properties by performing first-principles computations. It is shown that incorporating benzo-heterocyclic rings into CPs can significantly modulate the electronic structures of CPs and broaden the spectral absorption, suitable for visible-light-driven OWS.

[A new dihydrostilbene from aerial part of Cannabis sativa].

The present study investigated the chemical constituents in the aerial part of Cannabis sativa. The chemical constituents were isolated and purified by silica gel column chromatography and HPLC and identified according to their spectral data and physicochemical properties. Thirteen compounds were isolated from the acetic ether extract of C.

The mechanism of non-coding RNAs in medulloblastoma.

Medulloblastoma (MB) is one of the most common malignant tumors of the central nervous system in children. Although surgery, radiotherapy and chemotherapy have resulted in considerable progress in the treatment of this disease, the prognosis of patients with MB remains very poor. Therefore, highly specific molecular targeted treatment, which can improve the therapeutic efficacy and reduce the side effects of MB, has become a research hotspot.

Complications of thoracoscopic talc insufflation for the treatment of malignant pleural effusions: a meta-analysis.

Background: Talc pleurodesis is an effective treatment for malignant pleural effusions (MPEs). This study was designed to estimate complication rates of thoracoscopic talc insufflation.

Methods: Literature search was conducted in electronic databases and studies were selected if they reported complication rates of thoracoscopic talc insufflation in cancer patients with MPEs.

[Control effects of different herbicides on weeds as well as their effects on growth and deve-lopment of broomcorn millet].

Selecting a herbicide suitable for broomcorn millet is a key issue in high efficiency and safe production of broomcorn millet and ecological environment improvement. We compared the control effects of 22 different herbicides on weeds as wells as their effects on growth and development of glutinous millet (Yumi 2) in the field. The results showed that, 1) soil applied Goyou, Butachlor, atrazine, and Benzipram, and stem- and leaf-applied WP mixture of tribenuron-methyl·carfentrazone-ethyl·MCPA-Na, Sigma Broad, Tengjing, Taoshi·Youxian and Kuofei had little phytotoxi-city, with broomcorn millet seedlings growing normally, and the other herbicides had phytotoxicities on broomcorn millet.

Inhibition of metabotropic glutamate receptor 1 suppresses tumor growth and angiogenesis in experimental non-small cell lung cancer.

Metabotropic glutamate receptor 1 (mGlu1 receptor) is expressed in many cancer cell types as compared to normal counterparts underscoring its potential role in tumor behavior. The aim of present study was to test the role of mGlu1 receptor in experimental non-small cell lung cancer (NSCLC). First, protein expression of mGlu1 receptor was higher in human NSCLC cell lines, including both adenocarcinoma and squamous carcinoma subtypes, when compared to normal bronchial epithelial cells.

Aquaporin 3 knockdown suppresses tumour growth and angiogenesis in experimental non-small cell lung cancer.

Non-small cell lung cancer (NSCLC) is one of the most common diseases encountered in medical oncology practice. The aim of the present study was to test the antitumour effects of short-hairpin RNA targeting aquaporin 3 (AQP3) in experimental NSCLC. Expression of AQP3 was suppressed in human A549 and H1299 NSCLC cell lines by short-hairpin RNA-mediated silencing.
