MiR-148b suppressed non-small cell lung cancer progression via inhibiting ALCAM through the NF-kappa B signaling pathway

Background Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide. MiRNAs are recognized as important molecules in cancer biology. The aim of the study was to identify a novel biomarker miR-148b and its mechanism in the modulation of NSCLC progression. Methods The expressional level of miR-148b was analyzed by RT-PCR. The effect of miR-4317 on proliferation was evaluated through 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2Htetrazolium bromide (MTT) assay. The effect of miR-148b on the metastasis of NSCLC was detected through transwell assays. The verification of the target of miR-148b was assessed by TargetScan and dual-luciferase reporter assay. The related proteins in this study were analyzed by western blot. Results Our findings confirmed that miR-148b was decreased in NSCLC and NSCLC patients with lower expression exhibited poorer overall survival (OS). Increasing miR-148b significantly repressed proliferation, invasion and migration. More importantly, activated leukocyte cell adhesion molecule (ALCAM) was determined as the direct target of miR-148b, and reintroduction of ALCAM attenuated miR-148b effect on the progress of NSCLC. In addition, NF-kappa B signaling pathway was modulated by miR-148b/ALCAM axis. Conclusions Our results indicated that miR-148b is able to suppress NSCLC growth and metastasis via targeting ALCAM through the NF-kappa B pathway. These findings provided new evidence that miR-148b serves as a potential biomarker and novel target for NSCLC treatment.

A Comparative Investigation on Bioactivity and Antibacterial Properties of Sol-Gel Derived 58S Bioactive Glass Substituted by Ag and Zn

The bioactive glass systems of xAg(2)O-SiO2-P2O5-CaO and xZnO-SiO2-P2O5-CaO (x = 2 and 4% mol) were successfully synthesized through sol-gel method. The effect of silver and zinc contents on the in-vitro formation of hydroxyapatite (HA), cell viability, and antibacterial properties were studied. The HA formation and its microstructure were investigated through scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction analysis (XRD). The results showed that the rate of crystalline HA formation on SiO2-P2O5-CaO-xAg(2)O bioactive glass, in which x = 0 and 2, (B (58S) and BA2), was higher than other specimens. The evaluation methods of 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and alkaline phosphatase (ALP) illustrated that low silver (2% Ag2O) amount had a stimulating influence on both differentiation and proliferation promotion of cells (G292 osteoblastic). Furthermore, the antibacterial investigations showed that Ag bioglass samples had better antibacterial effect in comparison to Zn bioglass samples. Accordingly, the results revealed that specimen BA2 can be a good candidate for bone tissue application due to its significant bioactivity, antibacterial potential and optimal cell viability.

Protective Effects of Nicotinamide Riboside on H2O2-induced Oxidative Damage in Lens Epithelial Cells

Purpose: To investigate the protective effects of nicotinamide riboside (NR) on oxidative damage in hydrogen peroxide (H2O2)-exposed human lens epithelial cell lines (SRA01/04) and the possible mechanisms underlying its protective effects. Materials and methods: SRA01/04 cells were divided into three groups: the control (CON) group, model (H2O2) group and treatment (NR+H2O2) group. Superoxide dismutase (SOD), catalase (CAT) and total glutathione (GSH) levels were detected to evaluate oxidative damage induced by different concentrations of H2O2 in SRA01/04 cells. After SRA01/04 cells were treated with NR and/or H2O2, cell viability was evaluated using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and Hoechst staining, cell apoptosis was analysed using flow cytometry, reactive oxygen species (ROS) were measured with the DCFH-DA probe, and mitochondria were stained with MitoTracker to measure the mitochondrial membrane potential (MMP). In addition, western blotting was performed to detect the levels of proteins associated with apoptosis and related signalling pathways. Results: H2O2 induced oxidative damage in SRA01/04 cells by inhibiting the activity of SOD and CAT and reducing total GSH levels. Treatment of SRA01/04 cells with NR significantly increased cell viability and reduced cell apoptosis and ROS generation, whereas SOD and CAT activities and total GSH and MMP levels were improved by the NR treatment in an H2O2-exposed cell model. Furthermore, NR significantly inhibited the activation of the MAPK pathway but promoted activation of the JAK2/Stat3 pathway compared with the model group. Conclusions: NR may alleviate oxidative damage by targeting the MAPK and JAK2/Stat3 pathways in H2O2-treated SRA01/04 cells. NR may represent anovel drug for preventing or treating cataracts.

Catalytic Reductions Without External Hydrogen Gas: Broad Scope Hydrogenations with Tetrahydroxydiboron and a Tertiary Amine

Facile reduction of aryl halides with a combination of 5% Pd/C, B-2(OH)(4), and 4-methylmorpholine is reported. Aryl bromides, iodides, and chlorides were efficiently reduced. Aryl dihalides containing two different halogen atoms underwent selective reduction: I over Br and Cl, and Br over Cl. Beyond these, aryl triflates were efficiently reduced. This combination was broadly general, effectuating reductions of benzylic halides and ethers, alkenes, alkynes, aldehydes, and azides, as well as for N-Cbz deprotection. A cyano group was unaffected, but a nitro group and a ketone underwent reduction to a low extent. When B-2(OD)(4) was used for aryl halide reduction, a significant amount of deuteriation occurred. However, H atom incorporation competed and increased in slower reactions. 4-Methylmorpholine was identified as a possible source of H atoms in this, but a combination of only 4-methylmorpholine and Pd/C did not result in reduction. Hydrogen gas has been observed to form with this reagent combination. Experiments aimed at understanding the chemistry led to the proposal of a plausible mechanism and to the identification of N,N-bis(methyl-d(3))pyridin-4-amine (DMAP-d(6)) and B-2(OD)(4) as an effective combination for full aromatic deuteriation.

Pyrrolidine-based quaternary ammonium salts containing propargyl and hydrophobic C-12 and C-16 alkyl chains as corrosion inhibitors in aqueous acidic media

A new series of industrially relevant pyrrolidine based quaternary ammonium salts containing propargyl motif and hydrophobic C-12, C-16 alkyl chains were synthesized in excellent yields and evaluated for mild steel corrosion in 1 M HCl. FT-IR, NMR, and TGA were analyzed to characterize these corrosion inhibitors. The performance of these corrosion inhibitors was examined by gravimetric weight loss, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization (PDP), and theoretical calculations using density functional theory (DFT) methods. The surface morphology of mild steel samples was studied by UV-vis spectroscopy, scanning electron microscopy (SEM) and x-ray photoelectron spectroscopy (XPS). Results revealed that the inhibition capabilities of corrosion inhibitors N, N-dipropargylpyrrolidium bromide (DPPB), N-dodecyl, N-propargylpyrrolidium bromide (DDPPB), N-hexadecyl, N-propargylpyrrolidium bromide (HDPPB) are concentrations, immersion time and temperature-dependent, and found to be very good inhibitors even at a meager concentration of 60.3 mu mol L-1 with an efficiency value 92.6, 93.7, and 96.2%, respectively. The inhibition efficiency order of these corrosion inhibitors, as shown by gravimetric and electrochemical studies, is as follows: HDPPB > DDPPB > DPPB. The inhibition efficiencies obtained from gravimetric weight loss, PDP. and EIS measurements are in good agreement. The thermodynamic parameters such as E-a, K-ads, Delta G degrees(mic), and Delta G degrees(ads), were determined. As compare to Delta G degrees(mic), the more negative Delta G degrees(ads) values suggested favorable adsorption over the micellization.The critical micelle concentration (CMC) values of DPPB. DDPPB, and HDPPB were found to be 35.5, 31.8, and 30.0 mmol L-1. At CMC, the percent surface coverage was approximate to 90% revealed that the monolayer formation by the inhibitor mole- cules at the metalisolution interface is almost complete before the concentrations reach their CMC values. Electrochemical studies suggested that corrosion inhibitors DPPB and DDPPB act as a mixed type with predominantly cathodic inhibitors, while HDPPB serves as a cathodic inhibitor. Surface analysis by UV-vis spectroscopy, SEM. and XPS supported the adsorption of inhibitor molecules on the mild steel surface. The DFT analysis is in good agreement with the experimentally obtained results on the molecular structure and adsorption strength. (C) 2020 Elsevier B.V. All rights reserved.

MicroRNA-296 functions as a tumor suppressor in breast cancer by targeting FGFR1 and regulating the Wnt/beta-catenin signaling pathway

OBJECTIVE: Breast cancer (BC) is a common malignancy all over the world. However, the detailed mechanism underlying BC progression remains incompletely understood. MicroRNAs (miRNAs) have been observed to play crucial roles in tumorigenesis. The present study aimed to determine the expression and function of miR-296 in BC. PATIENTS AND METHODS: MiR-296 expressions in BC tissue samples and cell lines were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). After that, we performed functional assays, including MTT (3-(4,5-dimethyl thiazol-2-yl)-2.5-diphenyl tetrazolium bromide) assays and transwell assays, to show the functions of miR-296 in BC cell proliferation, invasion and migration. Immunological histological chemistry (INC) assays were carried out to detect the expression levels of fibroblast growth factor receptor 1 (FGFR1) in BC tissue samples. Western blot was used to explore potential mechanisms of miR-296 in regulating BC progression. A Luciferase reporter assay was carried out to confirm the target gene of miR-296. RESULTS: Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) results demonstrated a significant decrease of miR-296 expressions in BC when compared to the corresponding normal controls. In addition, the decreased miR-296 was correlated with the malignant phenotypes and poorer prognosis of BC patients. The functional assays indicated that miR-296 restoration could repress the proliferation, invasion and migration abilities of BC cells. Moreover, the results of the current study revealed that miR-296 exerted the repressive functions in BC cells via regulating FGFR1, the Wnt/beta-catenin signaling pathway and EMT. Additionally, miR-296 up-regulation could inhibit in vivo BC cell growth. CONCLUSIONS: All these findings indicated that miR-296 exerted anti-BC functions, providing novel therapeutic strategies in BC treatment.

Improvement in the hydrodesulfurization of dibenzothiophene over supported NiMoW catalysts

Various supported NiMoW sulfided catalysts were synthetized and tested in the hydrodesulfurization (HDS) of dibenzothiophene (DBT). The influence of cetyl trimethyl ammonium bromide (CTAB) on the properties of titania, silica and Si-Ti mixed oxide, prepared by sol-gel and used as supports, was evaluated. The active metals were then sequentially co-impregnated on the carrier. For all catalysts, the Ni/[Ni(MoW)] and Mo/W atomic ratios were kept constant and equal to 0.5 and 1, respectively. In addition, the total metal content was 18 wt% for each sample. All catalysts were characterized by BET, TEM, XRD and UV-Vis. The use of CTAB as a surfactant influences the textural properties of the supports. Among the studied samples, the best catalyst was NiMoW/Si-Ti, which showed a DBT conversion of 94% after 5 h of reaction at 320 degrees C and 5.3 MPa. For comparison, a commercial NiMo/Al2O3 catalyst was used as a reference.

Surfactant induced formation of flower-like V2O5 microspheres as cathode materials for rechargeable magnesium batteries

Flower-like V2O5 microspheres were synthesized via a facile hydrothermal route with hexadecyl trimethyl ammonium bromide (HTAB) surfactant. However, the irregular V2O5 assemblies formed in the absence of HTAB. In particular, the cathode based on V2O5 microflowers can deliver superior discharge capacity, better cycling stability, and enhanced rate capability, compared with that based on irregular assemblies. Specially, it can deliver considerable discharge specific capacity (an initial capacity of 126.2 mAh g(-1) at 50 mA g(-1)), good cycling stability (90.7 mAh g(-1) after 80 cycles), and enhanced rate capability (above 60 mAh g(-1) at 200 mA g(-1)). The improved electrochemical performance for V2O5 microflowers may be due to the increased specific surface area, interspace, and flexibility. The discharge-charge mechanism was investigated by X-ray diffraction and X-ray photoelectron spectroscopic results. This work indicates the important role of the surfactant on morphology control of cathode active materials for the promotion of electrochemical performance of rechargeable magnesium batteries.

Tumor microenvironment-responsive and oxygen self-sufficient oil droplet nanoparticles for enhanced photothermal/photodynamic combination therapy against hypoxic tumors

The combination of photothermal and photodynamic therapy (PTT/PDT) shows pronounced potential as a prominent therapeutic strategy for tumor treatment. However, the efficacy is limited by insufficient tumortargeted delivery of PTT and PDT reagents and the hypoxic nature of the tumor microenvironment. To overcome these limitations, tumor acidity-responsive lipid membrane-enclosed perfluorooctyl bromide oil droplet nanoparticles (NPs) surface modified with N-acetyl histidine-modified D-a-tocopheryl polyethylene glycol 1000 succinate (PFOB@IMHNPs) were developed, capable of co-delivering oxygen, IR780 (a photothermal agent) and mTHPC (a photodynamic sensitizer) into tumors. Through self-sufficient oxygen transportation in combination with promotion of cellular uptake upon acid-triggered generation of surface positive charge, the PFOB@IMHNPs effectively delivered IR780 and mTHPC and produced singlet oxygen within hypoxic TRAMP-C1 cells following exposure to irradiation at 660 nm. This led to effective killing of hypoxic cancer cells in vitro. Importantly, when irradiation at 808 and 660 nm was carried out, PT/PD combination therapy utilizing PFOB@IMHNPs dramatically suppressed the growth of TRAMP-C1 tumors through effective tumor-targeted cargo delivery and relief of tumor hypoxia. Our results suggest the high potential of the PFOB@IMHNPs developed in this study in clinical application for cancer treatment.

Evaluation of nonlinear optical properties of quaternary chalcogenide halides Ba4Si3Se9Br2 and Ba4Ge3Se9Br2

The quaternary chalcogenide halides Ba4Si3Se9Br2 and Ba4Ge3Se9Br2 were obtained in the form of crystals from reactions of binary selenides and bromides at 1173 K and in the form of phase-pure polycrystalline samples from reactions at 1023 K. They adopt noncentrosymmetric crystal structures, as determined from single-crystal X-ray diffraction data (hexagonal, space group P6(3), Z = 2; a = 10.1672 (5) angstrom, c = 12.4362 (6) angstrom for Ba4Si3Se9Br2; a = 10.2345 (4) angstrom, c = 12.5306 (5) angstrom for Ba4Ge3Se9Br2). The structures contain discrete Tt(3)Se(9)(6-) rings (Tt = Si, Ge) which are built up from corner-sharing TtSe(4) tetrahedra and which are separated by Ba2+ and Br- ions. Relative to the benchmark infrared nonlinear optical (NLO) material AgGaS2, the second harmonic generation (SHG) response is more intense for Ba4Si3Se9Br2 (3.2 x ) and Ba4Ge3Se9Br2 (3.5 x ) over particle sizes of 20-40 mm. The measured optical band gaps are 2.96 eV for Ba4Si3Se9Br2 and 2.60 eV for Ba4Ge3Se9Br2. Both compounds melt congruently (778 degrees C for Ba4Si3Se9Br2 and 731 degrees C for Ba4Ge3Se9Br2). The calculated birefringence is small, which accounts for the non-phase-matching behaviour observed experimentally. (C) 2020 Elsevier B.V. All rights reserved.
