Self-supported nickel cobalt carbonate hydroxide nanowires encapsulated cathodically expanded graphite paper for supercapacitor electrodes

The self-standing electrode materials with large surface area and high electronic conductivity have attracted intensive attention in energy storage devices. Herein, the expanded graphite paper (EGP) is fabricated via a controlled cathodic expansion in acetonitrile with tetrabutylammonium bromide at 10 V. The as-prepared EGP exhibits a three-dimensional porous structure with large specific surface area and high electronic conductivity, which is a favorable support for in situ growing nickel cobalt carbonate hydroxide (NiCo-CH) nanowires via a simple hydrothermal method. The as-prepared NiCo-CH@EGP composite achieves high areal capacity of 2.55 C cm(-2) at 0.5 mA cm(-2), and still remains 1.38 C cm(-2) even at 60 mA cm(-2) . The assembled NiCo-CH@EGP//activated carbon asymmetric supercapacitor exhibits the maximum energy density of 0.30 mWh cm(-2) at a power density of 0.92 mW cm(-2) , and a suitable cyclic stability with the capacity retention of 78.1 % after 10,000 cycles at 20 mA cm(-2). The results indicate that the self-standing NiCo-CH@EGP is a potential electrode material for energy storage devices. (C) 2020 Elsevier Ltd. All rights reserved.

Effect of prescribed fires on the export of dissolved organic matter, precursors of disinfection by-products, and water treatability

In this study, we report for the first time the effect of prescribed fires on the export of dissolved organic matter (DOM) and precursors of disinfectant by-products (DBPs) from periodically (every 2-3 years) and seasonally (i.e., dormant and growing) burned forest fuel materials (i.e., live vegetation, woody debris, and detritus [litter and duff]) and treatability of its rainwater leachate. Periodically applied (every 2-3 years for 40 years) prescribed fires decreased total fuel load (62 10%), primarily detrital mass (75 +/- 2%). How-ever, functional groups (i.e., phenolic compounds, proteins, carbohydrates, aromatic [1-ring], polycyclic aromatic hydrocarbons [PAHs], and lipids) attached to DOM of ground solid materials did not change significantly. Outside rainwater leaching (from forest fuel materials) experiments showed that the leaching capacity of dissolved organic carbon (DOC) from burned litter samples decreased by 40 +/- 20% regardless of burning season when compared to unburned litter samples. The leaching of total dissolved nitrogen (TDN), dissolved organic nitrogen (DON), ammonium (NH4+), and reactive phosphorus (PO43-) from burned materials decreased between 40 and 70% when compared to unburned materials. Also, DOM composition was affected by prescribed fire, which partially consumed humic-like substances based on fluorescence analyses. Thus, periodically applied prescribed fires also resulted in a reduction of trihalomethane (THM) (42 +/- 23%) and haloacetic acid (HAA) (42 +/- 20%) formation potentials (FPs), while DOC normalized reactivity of THM and HAA FPs did not change significantly. Additionally, the leaching of Nnitrosodimethylamine (NDMA) precursors, bromide ion (Br-), and selected elements (K, Ca, Mg, Mn, Fe, S, Na, B, and Al) were not significantly affected by prescribed fires. Finally, coagulant (i.e., alum and ferric) dose requirements and coagulation efficiencies were similar (i.e., removal of DOC, precursors of THMs and HAAs were 52-56%, 69-70%, 78-79%, respectively) in unburned and pre-burned leachate samples.

Effects of bromide-enriched natural seawater culture medium on protein and monoterpenes output of Ochtodes secundiramea (Rhodophyta, Gigartinales)

Benthic marine algae, especially Rhodophyta, are within a well-known marine group able to produce secondary metabolites with bioactive properties. Among them are halogenated terpenes, synthesized by vanadium-dependent haloperoxidase (V-BPO). The red alga Ochtodes secundiramea (Montagne) M. Howe produces high amounts of halogenated monoterpenes (HMT) which have the potential to control phytopathogenic fungi. Culture closed a system is a tool used to manipulate conditions to increase the synthesis of HMT and other metabolites. The apical segments of O. secundiramea were cultivated in a bioreactor, either in seawater enriched with half strength von Stosch’s solution (VSES/2) without (control) and with the addition of 250 mg L-1 bromine (treatment). In response to these conditions, specific growth rate, HMT profile, soluble protein, phycobiliproteins, soluble carbohydrate, and chlorophyll as well as the V-BPO activity, uptake, and accumulated bromine within the biomass were evaluated. The treatment did not promote significant alterations in the growth but increased the V-BPO activity and bromine uptake and incorporation (2.5 fold). No changes in the HMT profiles of the extracts from both cultures conditions were observed by gas chromatography-mass spectrometry analyses, whereas the values of total soluble protein and phycobiliproteins were 2 fold higher in samples from the bromine-enriched medium when compared to samples from control. These results support the evidences of protective effects promoted by V-BPO activity. Furthermore, carbohydrate and chlorophyll contents were not affected by experimental conditions. These results provided new low-cost strategies that can be applied to increase of certain biomass components, which here are algal proteins, especially in Rhodophyta-based biotechnological industries for food and agriculture.

Refolding of acid denatured cytochrome c by anionic surface-active ionic liquid: Choice of anion plays key role in refolding of proteins

This study was performed to check the effect of temperature on the refolding of acid-denatured horse heart cytochrome c (h-cyt c) at pH 2.0 under the influence of anionic surface active ionic liquid (SAIL) 1-butyl-3-methylimidazolium octyl sulfate ([C(4)mim][C8OSO3]), various techniques were performed viz. UV-vis, steady-state fluorescence, time-resolved fluorescence, circular dichroism (CD), FT-IR and dynamic light scattering. We found SAIL, [C(4)mim][C8OSO3] upon addition to the h-cyt c in unfolded state at pH 2.0, stabilized the molten globule (MG), which acts as an intermediate during the protein folding pathway. The investigation of the refolding of h-cyt c in an unfolded state with [C(4)mim][C8OSO3] shows a surfactant like behavior and stabilizes the MG-like state with the help of electrostatic and hydrophobic interactions. The creation of an MG-like state reveals the presence of a regular structure formed in the presence of SAIL [C(4)mim][C8OSO3]. The thermodynamic parameters of the refolding of h-cyt c by [C(4)mim][C8OSO3] were also quantified at various temperatures (25 degrees C-40 degrees C). Them value calculated for refolded states of h-cyt c by [C(4)mim][C8OSO3] shows a noticeable difference. The lower values of m (at higher temperatures) suggest less efficient refolding. This shows the refolding ability of the [C(4)mim][C8OSO3] decreases with increasing the temperature. Moreover, the anionic SAILs were efficiently utilized in the protein renaturation studies and could be effectively used to solve problems of misfolding and aggregation of proteins.

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.
