A Scalable H2O-DMF-DMSO Solvent Synthesis of Highly Luminescent Inorganic Perovskite-Related Cesium Lead Bromides

All-inorganic cesium lead bromide perovskites have attracted a lot of attention because of their excellent optical properties that can potentially be applied in various optical devices. However, large-scale preparation of cesium lead bromide perovskites with outstanding optical performance is still hindered by the poor solubility of CsBr in polar aprotic solvents. In this work, a water/dimethylsulfoxide (DMSO)/dimethylformamide (DMF) system is demonstrated for the synthesis of inorganic cesium lead bromide perovskites, where the introduction of water can effectively address the dissolution issue of Cs+ ions. Large-scale synthesis of pure-phase emissive Cs4PbBr6 with a product yield of up to 73% is achieved and the photoluminescence quantum yield of resulting product reaches as high as 76%. The origin of the light emission is further revealed by the photoluminescence evolution of the colored Cs4PbBr6 single crystals. Furthermore, reversible phase transitions between Cs4PbBr6, CsPbBr3 and CsPb2Br5 are achieved by changing solely the water content, which paves the way for the recycle of the mother solution of Cs4PbBr6 without generation of additional hazardous waste. The three-solvent-based synthetic approaches enable an economical, robust, and large-scale production for all-inorganic cesium lead bromide perovskites.

ZnO nanorods as efficient catalyst for the green synthesis of thiophene derivatives: Investigation of antioxidant and antimicrobial activity

In this work, thiophene derivatives were synthesized in good yields via multicomponent reaction of isoquinoline, alkyl bromides, activated acetylenic compounds, isothiocyanates, and catalytic amounts of ZnO nanorods (NRs) at room temperature under solvent-free conditions. This procedure for the synthesis of thiophene derivatives is green, easy, and simple with excellent yield. In addition, DPPH radical scavenging and ferric reduction power experiment has been studied for the evaluation of the antioxidant activity of some prepared thiophenes, for example, 5b, 5d, 5e, and 5f. As outcome, the compound 5d exhibited a noteworthy radical trapping activity and excellent reducing ability than synthetic antioxidants such as butylated hydroxytoluene (BHT) and 2-tertbutylhydroquinone (TBHQ). Moreover, the antimicrobial activity of some synthesized thiophenes was confirmed by employing the disk diffusion test on Gram-positive and Gram-negative bacteria. The obtained results of disk diffusion test showed that compounds 5b, 5d, 5e, and 5f prevented bacterial growth.

Augmented therapeutic efficacy of 5-fluorouracil in conjunction with lantibiotic nisin against skin cancer

Chemotherapy, a gold standard for treating most of the cancers, involves drastic side-effects and multidrug resistance. An attractive alternative is development of combination therapy employing antimicrobial peptides with chemotherapeutic drugs. In vivo studies: Anti-cancer therapeutic efficacy of 5-fluororuacil (5-FU) in conjunction with nisin (50 mg/kg body weight) was evaluated against murine skin cancer, in terms of tumor biostatistics, histopathology, electron microscopy, infrared spectroscopy and transcriptional studies. In vitro studies: Dose and time dependent cytotoxicity of agents were assessed against A431 cell line using MIT assay, LDH assay and acridine orange/ethidium bromide dual staining. Significant percentage decrease(s) in mean tumor volume and tumor burden were observed in nisin+ 5-FU combination treated groups as compared to alone treated groups. Histoarchitecture of treated skins demonstrated restoration towards normal skin tissue (being highest in the combination group). Modulation of apoptotic, angiogenic and proliferative genes were observed in treated groups. IC 5 0 of combination was found to be 2 mu g/ml as compared to nisin alone (32 mu g/ml) and 5-FU alone (16 mu g/ml) with combination index of 0.188. Dual staining showed that rate of induction of apoptosis was higher in the combination group as compared to single agents. Nisin and 5-FU in combination were found to be synergistic both in vivo and in vitro. (C) 2019 Published by Elsevier Inc.

(2-Carboxyethyl) dimethylsulfonium bromide supplementation in non-fish meal diets for on-growing grass carp (Ctenopharyngodon idella): Beneficial effects on immune function of the immune organs via modulation of NF-kappa B and TOR signalling pathway

The immune function of immune organs is extremely crucial for maintaining organism health status, which ultimately affects fish growth. Our previous study has found that dietary supplementation of (2-carboxyethyl) dimethylsulfonium Bromide (Br-DMPT) in non-fish meal (NFM) diet could promote the growth of grass carp (Ctenopharyngodon idella), whereas the underlying reason or mechanism for this results is largely unclear. Herein, we further explored whether dietary supplementation of Br-DMPT promoted fish growth is connected with the enhanced immune function in the immune organs (the head kidney, spleen and skin). In this study, 540 fish (216.49 +/- 0.29 g) were irregularly distributed to six groups with three replicates (30 fish replicate 1) and fed corresponding diets group containing a fish meal (FM) diet group and five different NFM diets supplemented with gradational Br-DMPT (0-520.0 mg/kg level) group for 60 days. After the 60-days feeding trial, 8 fish from each replicate were selected and then conducted a challenge test with A. hydrophila for 14 days. Our results indicated that in the NFM diets, appropriate Br-DMPT: (1) significantly decreased the morbidity of skin haemorrhage and lesion after A. hydrophila infection (P < 0.05). (2) significantly improved the innate and adaptive immune components (lysozyme, complement 3, immunoglobulin M and antibacterial peptides et al.) (P < 0.05). (3) increased the gene expressions of main anti-inflammatory cytokines partially by referring to TOR signalling pathway, and decreased the gene expressions of main pro-inflammatory cytokines partially by referring to NF-kB signalling pathway (P < 0.05). Strikingly, no statistical difference could be found in the most of above immune parameters between 260.0 mg/kg Br-DMPT diet group and FM diet group (P > 0.05). Taken together, in non-fish meal diet, appropriate supplementation of Br-DMPT could improve the disease resistance capacity, non-specific immunity and ameliorate inflammation, and simultaneously could mitigate these adverse effects induced by the non-fish meal diet in fish immune organs. Moreover, this study may be helpful to decipher the underlying mechanisms of how Br-DMPT promote fish growth by immune organs and also provide scientific theoretical evidence for the future application of Br-DMPT as a new immunopotentiator in aquaculture industry.

Refining the model to design alpha-chymotrypsin superactivators: the role of the binding mode of quaternary ammonium salts

A number of quaternary ammonium salts with bulky hydrophobic moieties are known to provoke the superactivation of alpha-chymotrypsin (alpha-CT) in aqueous solution. In particular, benzyl-substituted ammonium and dicationic ammonium-based salts have recently emerged as promising classes of compounds to induce alpha-CT superactivation and stabilization. Preliminary in silico modelling suggested the alpha-CT residue tryptophan 215 to be the major anchor point of these additives. In order to achieve a broader knowledge of the enzyme-additive interactions and to validate the modelling studies, new ammonium-based additives were designed and tested. The hydrophobic interaction resulted in being critical to improving superactivation, with [(2,3,5,6-tetramethyl-p-phenylene)dimethylene]bis[triethylammonium bromide] (bisEDuEAB) resulting as the most effective quaternary ammonium superactivating agent studied so far. Finally, a general agreement between in silico outcomes and kinetic parameters was observed, and data interpretation is discussed based on the proposed alpha-CT/additive binding modes.

Non-CTAB synthesized gold nanorods-based immunochromatographic assay for dual color and on-site detection of aflatoxins and zearalenones in maize

New developing gold nanorods (AuNRs) are promising alternatives of gold nanospheres in the immunochromatographic assay (ICA) for the rapid screening of mycotoxins in cereals because of their unique threedimensional structure. Nevertheless, cetyltrimethylammonium bromide (CTAB) was used to prepare of AuNRs without exception in previous reports, resulting in poor biocompatibility, cytotoxicology and difficulty for further functionalization. In this study, we used non-CTAB synthesized AuNRs with different colors as labels on ICA for the screening of four aflatoxins and total zearalenones. The results showed the non-CTAB synthesized AuNRs was more stable and easier for further functionalization than CTAB-based AuNRs. The visual detection limits of developed AuNR-ICA were 0.5 ng/mL for AFB1 and 1 ng/mL for ZEN, and the quantitative detection limits were 0.05 ng/mL for AFB1 and 0.27 ng/mL for ZEN, respectively. The assay could accomplish qualitative detection and quantitative analysis within 20 min. The results of the AuNR-ICA were comparable to those of HPLC-MS/MS for naturally contaminated maize samples, indicating the feasibility of the AuNR-ICA in practical use. Given these performances, the non-CTAB synthesized AuNRs showed great potential for use as an effective label in the ICA development.

Surfactant-modified titania for cadmium removal and textile effluent treatment together being environmentally safe for seed germination and growth of Vigna radiata

The present work describes synthesis, detailed characterization, and application of bare and surfactant-modified titania nanomaterials (NMs) for various wastewater treatment applications as individual cases like cadmium (Cd) removal, methylene blue (MB) dye degradation, and treatment of real textile and dyeing industry effluent. These NMs are used as adsorbents and photocatalysts in an indegenously developed end-to-end treatment process and a photocatalytic reactor for treatment of textile wastewater. The used NMs are suitably filtered and recovered for reuse; however, still this work focusses on the extent of potential risk and environmental safety of these engineered NMs towards seed germination and plant growth, in the event they escape wastewater treatment plants and reach out to natural water bodies and soil systems, accumulate over a period of time, and comes in contact with plant species. For synthesis, sol-gel method was utilized; cetyltrimethylammonium bromide (CTAB) and sodium dodecyl sulfate (SDS) were used as cationic and anionic surfactants, respectively, to act as particle growth templates and improve surface morphology. Detailed characterization involved XRD (X-ray diffraction), FTIR (Fourier-transform Infrared Spectroscopy), SEM (Scanning Electron Microscopy), TEM (Transmission Electron Microscopy), EDX (Energy Dispersive X-ray analysis), and BET (Brunauer-Emmett-Teller) surface area analysis. Improved morphology and surface properties, from irregular shape in Bare TiO2 to spherical shape in surfactant-modified titania, led to enhanced Cd removal and MB dye degradation efficiency. Bare TiO2 was used for complete treatment of textile wastewater, which took 5 h in achieving water quality, which is safe for discharge and reuse as per norms of Central Pollution Control Board (CPCB), Govt. of India. Phytotoxicity studies of these NMs at a wide concentration range (0-1000 mg L-1) were undertaken towards Vigna radiata, and 500 mg L-1 concentration was found to be optimally safe for seed germination and plant growth.

Simultaneous extraction of chromium and cadmium from bean samples by SrFe12O19@CTAB magnetic nanoparticles and determination by ETAAS: An experimental design methodology

In the present study, dispersive micro solid-phase extraction (DMSPE) integrated with electrothermal atomic absorption spectrometry (ETAAS) as a novel method was proposed for the simultaneous analysis of cadmium and chromium in bean samples. In this method, strontium hexaferrite (SrFe12O19) modified by cetyltrimethylammonium bromide (CTAB) along with chelating agent diethyldithiocarbamate (DDTC) were used to produce SrFe12O19@CTAB nanoparticles (NPs) as a magnetic adsorbent. This adsorbent was characterized using field emission scanning electron microscope (FESEM), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), thermogravimetric analysis (TGA), and differential scanning calorimetric (DSC). Response surface methodology (RSM) based on the central composite design CCD was applied to design the experiments and study of effective factors on the extraction efficiency. The experimental parameters include pH, shaking rate, adsorbent dosage, amount of ligand, and CTAB. The detection limits for chromium and cadmium ions were 0.08 and 0.09 mu g kg(-1) under the optimal experimental conditions, with standard deviations in the range of 1.7-5% and 1.2-6%, respectively (n = 4). The linear calibration was obtained in the range of 1-150 and 1-250 mu g L-1 for chromium and cadmium ions, respectively. Also, the recovery values of all samples were found in the range of 96 to 100% and 91 to 99%.

MiR-384-3p aggravates propofol induced apoptosis in developing neurons by targeting Wnt3a

Purpose: To evaluate the cytotoxicity of miR-384-3p toward propofol-treated neonatal rat hippocampal neurons and investigate its related molecular mechanism(s). Methods: Quantitative real-time polymerase chain reaction (qRT-PCR) was employed to determine miR-384-3p expression levels in propofol-treated neonatal rat hippocampal neurons. Cell apoptosis and cell viability were evaluated by flow cytometty analysis and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, respectively. Bioinformatics and dual-luciferase reporter assay were applied together to forecast and verify the interaction between miR-384-3p and Wnt3a. Wnt3a expression in transfected neonatal rat hippocampal neurons was assessed by Western blot assay. Results: Propofol induced apoptosis in developing neurons by upregulating miR-384-3p expression levels. Knockdown of miR-384-3p reduced propofol-induced apoptosis in developing neurons. Subsequent experiments indicated that miR-384-3p directly regulated Wnt3a expression via coupling with the 3′-untranslated region of Wnt3a. Furthermore, upregulation of Wnt3a expression levels alleviated propofol-induced cytotoxicity promoted by miR-384-3p (p < 0.01). Conclusion: MiR-384-3p aggravates propofol-induced apoptosis in developing neurons by targeting Wnt3a. A reaction mechanism is the microscopic path by which reactants are transformed into products.

Baicalin Inhibits Biofilm Formation and the Quorum-Sensing System by Regulating the MsrA Drug Efflux Pump in Staphylococcus saprophyticus

Staphylococcus saprophyticus (S. saprophyticus) is one of the main pathogens that cause serious infection due to its acquisition of antibiotic resistance. The efflux pump decreases antibiotic abundance, and biofilm compromises the penetration of antibiotics. It has been reported that baicalin is a potential agent to inhibit efflux pumps, biofilm formation, and quorum-sensing systems. The purpose of this study was to investigate whether baicalin can inhibit S. saprophyticus biofilm formation and the quorum-sensing system by inhibiting the MsrA efflux pump. First, the mechanism of baicalin inhibiting efflux was investigated by the ethidium bromide (EtBr) efflux assay, measurement of ATP content, and pyruvate kinase (PK) activities. These results revealed that baicalin significantly reduced the efflux of EtBr, the ATP content, and the activity of PK. Moreover, its role in biofilm formation and the agr system was studied by crystal violet staining, confocal laser scanning microscopy, scanning electron microscopy, and real-time polymerase chain reaction. These results showed that baicalin decreased biofilm formation, inhibited bacterial aggregation, and downregulated mRNA transcription levels of the quorum-sensing system regulators agrA, agrC, RNAIII, and sarA. Correlation analysis indicated that there was a strong positive correlation between the efflux pump and biofilm formation and the agr system. We demonstrate for the first time that baicalin inhibits biofilm formation and the agr quorum-sensing system by inhibiting the efflux pump in S. saprophyticus. Therefore, baicalin is a potential therapeutic agent for S. saprophyticus biofilm-associated infections.
