Reaction of small molecules O-2, NO, CO, and the Naldini salt (PPh3)(2)MnBr2: Characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction

Addition of 2 equiv. of PPh3 to MnBr2 in tetrahydrofuran (THF) solution under N-2 atmosphere results in the formation of Naldini salt (PPh3)(2)MnBr2 (1). Reaction of Complex 1 and O-2, NO, and CO (with reducing agent) leads to Complex (OPPh3)(2)MnBr2 (2), (PPh3)(2)Mn(NO)Br-2 (3), and (PPh3)(2)Mn(CO)(3)Br (4), respectively. Both Complexes 2 and 4 crystallize in the triclinic space group P-1 with a = 9.94 angstrom, b = 10.11 angstrom, c = 10.53 angstrom; alpha = 65.42 degrees, beta = 63.16 degrees, and gamma = 89.22 degrees of 2 and a = 10.23 angstrom, b = 12.26 angstrom, c = 14.44 angstrom and alpha = 97.03 degrees, beta = 104.34 degrees, and gamma = 106.33 degrees of 4. The isoelectronic replacement of 3CO with 2NO yields the {Mn(NO)(2)}(8) species (PPh3)(2)Mn(NO)(2)Br (5). The single crystal of 5 is in the monoclinic space group C2/c with a = 23.17 angstrom, b = 9.62 angstrom, c = 15.92 angstrom, and beta = 114.91 degrees. In the THF solution, Complex 5 serves as an NO source in the presence of NO trapping, Co(TPP), Co(TPP) = 5,10,15,20-tetraphenyl-21H,23H-porphine cobalt(II).

CircATP2B4 promotes hypoxia-induced proliferation and migration of pulmonary arterial smooth muscle cells via the miR-223/ATR axis

Background: Circular RNAs (circRNAs) function as important modulators in the progression of pulmonary arterial hypertension (PAH). Here, we aimed to discover the role and working mechanism of circATP2B4 in hypoxia-induced proliferation and migration of PASMCs. Methods: The proliferation, migration and apoptosis of pulmonary arterial smooth muscle cells (PASMCs) were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), wound healing assay and flow cytometry. The expression of circATP2B4, ATPase plasma membrane Ca2+ transporting 4 (ATP2B4), microRNA-223 (miR-223) and ATR serine/threonine kinase (ATR) was quantified by quantitative real time polymerase chain reaction (qRT-PCR). Circular RNA Interactome and microT-CDS were used to search the targets of circATP2B4 and miR-223, respectively. Dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay were used to validate the above predictions. Western blot assay was performed to detect the protein expression of ATR. Results: Hypoxia treatment promoted the proliferation and migration and impeded the apoptosis of PASMCs. A significant increase of circATP2B4 expression was observed in the serum of PAH patients and hypoxia-induced PASMCs compared with healthy volunteers and PASMCs under normoxia condition. MiR-223 is a target of circATP2B4, and the effects of circATP2B4 silencing on PASMCs were overturned by the transfection of anti-miR-223. ATR is a functional target of miR-223, and miR-223 inhibited the proliferation and migration while accelerated the apoptosis of PASMCs through targeting and down-regulating ATR. CircATP2B4 could up-regulate the level of ATR through sponging miR-223 in PSAMCs. Conclusion: CircATP2B4 potentiated hypoxia-induced proliferation and migration of PASMCs through the miR-223/ATR axis. Restoration of the level of miR-223 might be an effective therapeutic method for the treatment of PAH.

Fe3O4@Au/reduced graphene oxide nanostructures: Combinatorial effects of radiotherapy and photothermal therapy on oral squamous carcinoma KB cell line

Combination therapy including radiotherapy (RT) and photothermal therapy (PTT), as an alternative treatment for cancer treatment, recently has generated substantial interest. Graphene-based nanocarbons and gold content metallic nanoparticles, as one of the most attractive materials with their extraordinary physical and chemical properties, are extremely useful in this regard. We herein reported the effects of combination of cancer therapy including RT (doses of 2 and 4 Gy) and PTT (808 nm laser irradiation, NIR irradiation) as radio-photothermal therapy (RPTT) of KB oral squamous carcinoma cell line in the presence of Fe3O4@Au/reduced graphene oxide (rGO) nanostructures (NSs) at different concentrations. Fe3O4@Au/rGO NSs with different rGO contents have been synthesized by hydrothermal reaction method. They characterized by XRD, FE-SEM, TEM, EDS, FTIR and TGA. Cell viability for cytotoxicity, RT, PTT and RPTT were studied by MTT (3[4,5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay. High photothermal conversion efficiency of Fe3O4@Au/rGO NSs reaches to 61%. The resulting Fe3O4@Au NPs with approximate size of about 10-60 nm covered the rGO nanosheets with 40 wt% rGO at concentration of 20 mu g ml(-1), exhibited satisfactory cytotoxicity. They provided significant cell destruction under RT, PIT and specially RPTT in dose of 4 Gy. Furthermore, they have good biocompatibility on the healthy cells. Our results show that Fe3O4@Au/rGO NSs integrated with radiosensitization, photothermal therapy and their combination promising for nanomedicine and clinical applications.

Flotation Performance of Low-rank Coal in the Presence of Cetyltrimethyl Ammonium Bromide

The flotation enhancement mechanism and flotation kinetics of low-rank coal in the presence of cetyltrimethyl ammonium bromide (CTAB) were investigated. The contact angle of the coal sample increased by 46.07% and the attachment time between coal particles and a single air bubble decreased by 85.79% with increasing the concentrations of CTAB from 0 to 1 x 10(-4) M. Low concentrations of CTAB enhanced the flotation performance of low-rank coal, and the concentrate yield significantly increased by up to 8.59 percentage points with increasing the concentrations of CTAB from 0 to 1 x 10(-5) M at the cost of a lower increase in the ash content. However, the selectivity was reduced at high CTAB concentrations (5 x 10(-5) M and 10(-4) M). Six kinetic flotation models were employed to fit the flotation test data using the 1stOpt analysis software; the flotation rate constant (k), the maximum combustible recovery (epsilon (infinity)), the correlation coefficient (R (2)) and the modified flotation rate constant (k (m)) were calculated. Most models showed that the modified rate constant and the maximum combustible recovery of low-rank coal increased with the increasing concentrations of CTAB.

Effects of ionic liquid pretreatment on pyrolysis characteristics of a high-sulfur bituminous coal

Four different ionic liquids (ILs) were used to identify their extraction properties on high-sulfur bituminous coal. And the effect of ILs pretreatment on pyrolysis characteristic was investigated in a fixed-bed reactor. The imidazolium-based ILs used namely: 1-butyl-3-methyl-imidazolium chloride ([Bmim]Cl), 1-butyl-3-methyl-imidazolium bromide ([Bmim]Br), 1-butyl-3-methylimidazolium hydrogen sulfate ([Bmim]HSO4), 1-butyl-3-methyl-imidazolium tetrafluoroborate ([Bmim]BF4). All the selected ILs exhibited extraordinary extraction ability for oxygen-containing compounds, mainly furans and ethers. Among them, [Bmim]Cl got the highest extraction yields of 20.82% and performed selective extraction ability for sulfur-containing compounds with a relative content of 5.10% in light oils. Compared with pyridine pretreated coal (R-PY), the yields of CO and CO2 in pyrolysis gas showed increase trend when coal pretreated by ILs (R-ILs). The relative contents of tricyclic and larger PAHs, sulfur-containing compounds, and oxygen-containing compounds in tar from pyrolysis of [Bmim]Cl and [Bmim] Br treated coal increased significantly than R-PY tar, while phenols got decreased. High carbon number components from R-ILs tar reduced dramatically compared with R-PY tar, which was conducive to the upgrading of tar, after pretreated with ILs, the sulfur content was reduced. The crosslinks between coal macromolecules structure were destroyed after pretreated by ILs, and the pyrolysis products distribution had evident change. The oil phase yield got a substantial increase while [Bmim]Cl obtained highest oil yield of 24.89%.

Hybrid bromobismuthates: Synthesis, thermal stability and crystal structure of multicharged 3-ammoniopyridinium derivatives

All compounds are unstable and decompose slowly in humid air. According to DFT calculations the protonation of the amino group results in the increase of the electron affinity of the organic cation and leads to changes in the structure of the aminopyridine fragment of the cation. The C-NHn bond length values in 3-aminopyridinium (1.40 angstrom) and in 3-ammoniopyridinium (1.44 angstrom) derivatives allows to uniquely determine the protonation degree of the N atom.

Multi-scheme chemical ionization inlet (MION) for fast switching of reagent ion chemistry in atmospheric pressure chemical ionization mass spectrometry (CIMS) applications

A novel chemical ionization inlet named the Multi-scheme chemical IONization inlet (MION), Karsa Ltd., Helsinki, Finland) capable of fast switching between multiple reagent ion schemes is presented, and its performance is demonstrated by measuring several known oxidation products from much-studied cyclohexene and alpha-pinene ozonolysis systems by applying consecutive bromide (Br-) and nitrate (NO3-) chemical ionization. Experiments were performed in flow tube reactors under atmospheric pressure and room temperature (22 degrees C) utilizing an atmospheric pressure interface time-of-flight mass spectrometer (APi-ToF-MS, Tofwerk Ltd., Thun, Switzerland) as the detector. The application of complementary ion modes in probing the same steady-state reaction mixture enabled a far more complete picture of the detailed autoxidation process; the HO2 radical and the least-oxidized reaction products were retrieved with Br- ionization, whereas the highest-oxidized reaction products were detected in the NO3- mode, directly providing information on the first steps and on the ultimate endpoint of oxidation, respectively. While chemical ionization inlets with multiple reagent ion capabilities have been reported previously, an application in which the charging of the sample occurs at atmospheric pressure with practically no sample pretreatment, and with the potential to switch the reagent ion scheme within a second timescale, has not been introduced previously. Also, the ability of bromide ionization todetect highly oxygenated organic molecules (HOM) from atmospheric autoxidation reactions has not been demonstrated prior to this investigation.

Anchoring ultrafine Co3O4 grains on reduced oxide graphene by dual-template nanocasting strategy for high-energy solid state supercapacitor

Co3O4-based materials are regarded as superior electrode candidates in various energy storage devices due to their high theoretical capacity. Unfortunately, the poor electronic conductivity and huge volume expansion hamper their widespread applications. Therefore, nano-processing and introducing conductive matrix can view as the necessary methods to make Co3O4-based materials better for an advanced supercapacitor electrode. Herein, a dual-template nanocasting technique is proposed to design the ultrafine Co3O4 grains highly-dispersed on the reduced oxide graphene nanosheets (Co3O4/rGO-C), in which cetyltrimethyl ammonium bromide and silicate species are hired as the ideal soft and hard template, respectively. Co3O4 grains with size <10 nm can expose more active sites and thus exert more redox activities to enhance the capacitive performance. In additional, similar to 4 nm moderate pores are obtained in Co3O4/rGO-C after the hard template removing, which provides more diffusion channels for ion/electron rapid transport and also effectively alleviates the volume expansion on cycling. Consequently, the Co3O4/rGO-C electrode exhibits a remarkable specific capacitance (709.1 F g(-1) at 1 A g(-1)) and long-term endurance (91.2% after 6000 cycles). Furthermore, an assembled solid-state asymmetric device of Co3O4/rGO-C parallel to rGO delivers a super-high energy-density of 48.2 Wh kg(-1) at 750.5 W kg(-1). The high energy-density assists two devices in lightning a red light-emitting diode for 340 s. These results evidence the nanocasting strategy as an efficient method to achieve the advanced electrode materials for energy storage devices. (C) 2019 Elsevier Ltd. All rights reserved.

DNA INTERACTION, PHOTOCLEAVAGE AND THEORETICAL CALCULATIONS OF A RUTHENIUM(II) COMPLEX WITH HYDROXYQUINOLINE DERIVATIVE

The interaction of [Ru(bpy)(2)(ipq)](ClO4)(2) {bpy = 2,2′-bipyridine, ipq = 2-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)quinolin-8-ol} with calf thymus DNA were investigated by means of DNA viscosity and optical spectroscopic techniques of UV-visible absorption and emission spectral titrations, steady-state emission quenching with ferrocyanide, ethidium bromide competitive binding, and DNA thermal denaturation as well as density functional theoretical calculations. The results suggested that the complex binds to DNA via an classic intercalation mode with enhanced binding strength with respect to the parent analogue [Ru(bpy)(2)(ip)](ClO4)(2) {ip = imidazo[4,54][1,10]-phenanthroline}, owing to the larger plan area of ligand ipq as compared to that of ligand ip. Agarose gel electrophoresis showed that the complex also exhibited enhanced DNA photocleavage capacity on pBR 322 plasmid DNA under irradiation at 365 nm as compared with many hydroxyquinoline-free analogous ruthenium complexes.

Promotion of Cellular and Humoral Immunity against Foot-and-Mouth Disease Virus by Immunization with Virus-Like Particles Encapsulated in Monophosphoryl Lipid A and Liposomes

Virus-like particles (VLPs) have emerged as promising vaccine candidates against foot-and-mouth disease (FMD). However, such vaccines provide a relatively low level of protection against FMD virus (FMDV) because of their poor immunogenicity. Therefore, it is necessary to design effective vaccine strategies that induce more potent immunogenicity. In order to investigate the means to improve FMD VLP vaccine (VLPFMDV) immunogenicity, we encapsulated VLPs (MPL/DDA-VLPFMDV) with cationic liposomes based on dimethyldioctadecylammonium bromide (DDA) and/or monophosphoryl lipid A (MPL, TLR4 agonist) as adjuvants. Unlike inactivated whole-cell vaccines, VLPFMDV were successfully encapsulated in this MPL/DDA system. We found that MPL/DDA-VLPFMDV could induce strong cell-mediated immune responses by inducing not only VLP-specific IFN-gamma(+)CD4(+) (Th1), IL-17A(+)CD4(+) (Th17), and IFN-gamma(+)CD8(+) (activated CD8 response) T cells, but also the development of VLP-specific multifunctional CD4(+) and CD8(+) memory T cells co-expressing IFN-gamma, TNF-alpha, and IL-2. In addition, the MPL/DDA-VLPFMDV vaccine markedly induced VLP-specific antibody titers; in particular, the vaccine induced greater Th1-predominant IgG responses than VLPFMDV only and DDA-VLPFMDV. These results are expected to provide important clues for the development of an effective VLPFMDV that can induce cellular and humoral immune responses, and address the limitations seen in current VLP vaccines for various diseases.
