摘要：
Numerous long noncoding RNAs (lncRNAs) are abnormally expressed in breast cancer (BC), but the underlying mechanisms remain large unknown. Here, we aimed to investigate the functions and mechanisms of lncRNA cancer susceptibility candidate 9 (CASC9) in BC. Western blotting and quantitative real-time PCR (qRT-PCR) were performed to assess gene and protein expression, respectively. The proliferative and metastatic abilities of BC cells were tested by cell counting kit-8 and transwell assays, respectively. The formation of lymphatic vessels was detected by tube formation assay. Chromatin immunoprecipitation (ChIP) and dual luciferase reporter assays were performed to verify molecular interactions. CASC9 was found to be highly expressed in BC tissues and cell lines, and ectopic overexpression was positively associated with tumor volume, TNM stage, and lymph node metastasis. In addition, CASC9 silencing significantly inhibited the proliferation and invasion of BC cells, as well as BC-associated invasion and formation of lymphatic vessels of human dermal lymphatic endothelial cells. Mechanical studies demonstrated that CASC9 could be transcriptionally activated by STAT3 and elevate SOX4 expression by enhancing the acetylation of its promoter region. Our results illustrated that STAT3-activated CASC9 served as a tumor-promoting gene involved in promoting BC invasion and BC-associated formation of lymphatic vessels by upregulating SOX4 through altering H3K27ac level. This finding elucidated a new underlying network of CASC9 in the metastasis of BC.

摘要：
Isomeric diruthenium complexes with bis(ethynyl)pyridine as bridge core [2,6-bis(ethynyl)pyridine ( 1 ), 3,5-bis(ethynyl)pyridine ( 2 ), 2,5-bis(ethynyl)pyridine ( 3 )] were successfully prepared and characterized by 1 H NMR, 13 C NMR and elemental analysis. The electrochemical properties of complexes 1-3 were inves-tigated by cyclic voltammetry (CV) and square-wave voltammetry (SWV), and different potential differ-ence values were revealed and affected by N atom position and distance between redox metal centers. Electron absorption spectra showed that the absorption of the linear molecule 3 displayed a red shift relative to that of complexes 1 and 2 . The broad near-infrared absorption characteristic of the singly -oxidized complex 3 + revealed the existence of a mixed-valence state, which can be classified as a class II mixed-valence system according to the intervalence charge transfer (IVCT) absorption parameter Hab and <SIC> CYRILLIC CAPITAL LETTER GHE. These results indicated that 3 has higher conjugation and charge delocalization ability than isomers 1 and 2 . Density functional theory (DFT) calculations spin density distribution analysis further confirmed the above results, and time-dependent DFT showed the NIR multi-absorption of complex 3 +, and effec-tively attributed to Ru-C equivalent to C -> Ru IVCT absorption characteristics.(c) 2022 Elsevier B.V.

摘要：
In this work, cubic MnSe2 nanoparticles were firstly synthesized through a simple one-step hydrothermal procedure at low temperature using N2H4·H2O as a reductant as well as MnCl2 and Se powders as precursors. The crystalline structure, morphology, chemical composition, and element valence states of the synthesized samples were specifically investigated by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), X-ray photoelectron spectra (XPS), and Raman spectroscopy. It was found that the MnSe2 product mainly exists in a roughly cubic morphology with the sizes between 20 and 50 nm. In order to alleviate the aggregation, cubic MnSe2 nanoparticles were further ultrasonically dispersed on the surface of multi-walled carbon nanotubes (MWCNTs) to achieve an improved stability structure denoted as MnSe2/MWCNTs. Compared with the single components, the MnSe2/MWCNTs composite displays enhanced electrochemical sensing signals for chloramphenicol (CAP) derived from the synergistic catalytic performance of the corresponding components. After optimization of electrochemical assay parameters, an assay range of 8.00–5000.00 μM and a limit of detection (LOD) with 2.00 μM for CAP were obtained using the MnSe2/MWCNTs-based sensor. Finally, the application of the resulting sensor for CAP detection in food and biological fluids was evaluated with recoveries between 94.70 and 106.70 %, demonstrating that MnSe2/MWCNTs could be served as a preeminent sensing platform. To the best of our knowledge, this is the first report on the fabrication of MnSe2-based composite for electrochemical sensing applications.

摘要：
We report here a DTBP-mediated oxidative [4 + 2]/[3 + 2] annulation between 2-alkynylbenzaldehydes and terminal arylalkenes enabled by aldehyde C(sp2)–H functionalization for assembling a range of benzo[a]fluoren-5-ones with high step-economy, simple operation under metal-/solvent-free conditions and excellent functional group tolerance. This method is initiated from 2-alkynylbenzaldehyde reaction partners and provides a useful new strategy to construct complex benzo[a]fluoren-5-one scaffolds compared to existing protocols initiating from alkene reaction partners.

摘要：
Mannich-type polycondensation with 4,4’-diaminodiphenylmethane (DDM), 2,2-bis(4-hydroxyphenol) propane (BPA) and paraformaldehyde (PF) in different solvents was carried out to prepare main-chain benzoxazines. When pure CHCl3 was used as the solvent, the decomposition rate of PF in CHCl3 was very slow, thus preventing gelation caused by the formation of triazine in the early reaction, producing P(B-D)1 composed of partially closed and unclosed structures. The addition of alkaline triethylamine into CHCl3 (CHCl3/triethylamine = 6:1) greatly enhanced the decomposition rate of PF but gave a large triazine gel. The introduction of triethanolamine into CHCl3 was found to promote the decomposition of PF, enhance the polymerization rate, and prevent gelation caused either by the formation of triazine or by the ring-opening of oxazine ring through a solvation effect. Polymers P(B-D) 6~P(B-D)8 obtained in CHCl3/triethanolamine had a high-oxazine content and a high number molecular weight (Mn) near 8000. Further optimization of Mannich-type polycondensation in CHCl3/triethanolamine gave preferred conditions: a CHCl3/triethanolamine ratio of 4:1, a PF of 1.2 eq and a reaction time of 24 h. Compared with P(B-D)1 and P(B-D)3 (obtained in toluene/ethanol), P(B-D)9 obtained under the optimized conditions showed a higher Mn (10,000) and a higher yield (97.0%). The optimized conditions were also applicable for other kinds of diamines and bisphenols. Mannich-type polycondensation of diamines, bisphenols and PF was conducted in CHCl3, CHCl3/triethylamine, and CHCl3/triethanolamine, respectively. The products were greatly affected by the solvents used. Owing to the combination of alkalinity and solvation effect of triethanolamine, CHCl3/triethanolamine was preferable for Mannich-type polycondensation which gave main-chain benzoxazines possessing Mn up to 10,000, oxazine content >80.0% and yield >96.0%.
