The inhibition of enterovirus 71 induced apoptosis by Durvillaea antarctica through P53 and STAT1 signaling pathway

The infection of enterovirus 71 (EV71) resulted in hand, foot, and mouth disease and may lead to severe nervous system damage and even fatalities. There are no effective drugs to treat the EV71 virus and it is crucial to find novel drugs against it. Polysaccharide isolated from Durvillaea antarctica green algae has an antiviral effect. In this study, D. antarctica polysaccharide (DAPP) inhibited the infection of EV71 was demonstrated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), reverse transcription polymerase chain reaction, flow cytometry, and western blot. MTT assay showed that DAPP had no toxicity on Vero cells at the concentration 250 mu g/ml. Furthermore, DAPP significantly reduced the RNA level of EV71 in a dose-dependent manner. Moreover, DAPP inhibited the Vero cells apoptosis induced by EV71 via the P53 signaling pathway. Meanwhile, the expression of signal transducer and activator of transcription 1 and mammalian target of rapamycin were increased and the proinflammatory cytokines were significantly inhibited by DAPP. Taken together, these results suggested that DAPP could be a potential pharmaceutical against the infection of EV71 virus.

A-Site Cation Engineering for Efficient Blue-Emissive Perovskite Light-Emitting Diodes

Metal halide perovskites have been investigated for the next-generation light-emitting materials because of their advantages such as high photoluminescence quantum yield (PLQY), excellent color purity, and facile color tunability. Recently, red- and green-emissive perovskite light-emitting diodes (PeLEDs) have shown an external quantum efficiency (EQE) of over 20%, whereas there is still room for improvement for blue emissive PeLEDs. By controlling the halide compositions of chloride (Cl-) and bromide (Br-), the bandgap of perovskites can be easily tuned for blue emission. However, halide segregation easily occurrs in the mixed-halide perovskite under light irradiation and LED operation because of poor phase stability. Here, we explore the effect of A-site cation engineering on the phase stability of the mixed-halide perovskites and find that a judicious selection of low dipole moment A cation (formamidinium or cesium) suppresses the halide segregation. This enables efficient bandgap tuning and electroluminescence stability for sky blue emissive PeLEDs over the current density of 15 mA/cm(2).

Study of Liquid-Liquid Equilibrium of Aqueous Two-Phase Systems Based on Ethyl Lactate and Partitioning of Rutin and Quercetin

Two ethyl lactate (EL)-based aqueous two-phase systems (ATPSs) were studied at T = 298.15 K and atmospheric pressure. Sodium tartrate and potassium sodium tartrate organic salts have been used to form biphasic systems. To assess the phase splitting, binodal curves and tie-lines were obtained experimentally by the cloud point method and a technique, which consist of the density and refractive index, respectively. Binodal curves were fitted with the Merchuk equation obtaining a good fit. Moreover, modeling with the universal quasichemical thermodynamic equation was carried out to accurately represent the two-biphasic systems. Furthermore, experimental binodal curves obtained in this work and literature results for the same systems and for systems with EL and other salts were analyzed regarding their similarity. Finally, the application of the adopted ATPS in the partitioning of two flavonoids, rutin and quercetin, was studied in terms of the partition coefficients and the percentage of extraction. Rutin and quercetin showed better affinity to the EL-rich phase, evidencing that the use of the proposed ATPS may be a successful technique in the biotechnological industry for the separation of each flavonoid.

Sub-10 nm Polyamide Nanofiltration Membrane for Molecular Separation

To separate small molecules from the solvent with high permeability and selectivity, the membrane process is thought to be highly effective with much lower energy consumption when compared to the traditional thermal-based separation process. To achieve high solvent permeance, a sub-10 nm thick polyamide nanofiltration membrane was synthesized through interfacial polymerization of ethidium bromide (EtBr) and trimesoyl chloride (TMC). Thanks to the extremely low solubility of the EtBr monomer in the organic phase, the polymerization process was strictly limited at the interface of the water and hexane, leading to an ultrathin polyamide membrane with a thickness down to sub-10 nm. When used in nanofiltration, these ultrathin membranes display ultrafast water permeation of 40 liter per square meter per hour per bar (L m(-2) h(-1) bar(-1)), and a high Congo red rejection rate of 93 %. This work demonstrates a new route to synthesize ultrathin polyamide membranes by the traditional interfacial polymerization.

Indigo Carmine and 2,6-Dichlorophenolindophenol Removal Using Cetyltrimethylammonium Bromide-Modified Palm Oil Fiber: Adsorption Isotherms and Mass Transfer Kinetics

In the present work, the usefulness of cetyltrimethylammonium bromide-modified palm oil fiber (CTAB-modified POF) for the removal of indigo carmine (IC) and 2,6-dichlorophenolindophenol (2,6-DCPIP) from aqueous solutions was investigated. Raw, NaOH-treated, and CTAB-modified POF were characterized by Fourier-transform infrared (FT-IR) spectroscopy, elemental analysis, thermogravimetric-hyperdifferential scanning calorimetric (TG-HDSC) analysis, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The adsorption studies of IC and 2,6-DCPIP were performed in batch mode using CTAB-modified POF. The results showed that equilibrium was attained after a contact time of 30 minutes for IC and 20 minutes for 2,6-DCPIP. The maximum capacity of adsorption was obtained at pH = 2. The capacity of adsorption considerably increased with modified biosorbents and with increasing initial concentration of dyes. The ionic strength favors the increasing adsorption capacity of IC and does not affect the adsorption capacity of 2,6-DCPIP. The percentage of adsorption increased with increasing mass of the biosorbents. The nonlinear regression of adsorption isotherms showed that Freundlich (r(2) = 0.953; chi 2 = 4.398) and Temkin (r(2) = 0.986; chi 2 = 1.196) isotherms are most appropriate to describe the adsorption of IC and 2,6-DCPIP on CTAB-modified POF, respectively. The maximum adsorption capacities determined by the Langmuir isotherm were 275.426 and 230.423 mu mol center dot g(-1) for IC and 2,6-DCPIP, respectively. The linear regression of adsorption kinetics was best described by the pseudo-second-order model (R-2 >= 0.998). The diffusion mechanism showed that external mass transfer is the main rate controlling step. Desorption of the two dyes is favorable in the alkaline medium.

A Second Modification of Beryllium Bromide: beta-BeBr2

The synthesis of a second beryllium bromide modification, beta-BeBr2, was accomplished through recrystallization of alpha-BeBr2 from benzene in the presence of cyclo-decamethylpentasiloxane.

Interactions in the mixed micelles of monomeric and gemini surfactants: Influence of some co-solvents as a function of temperature

Mixed micellar behavior of a series of m-2-m cationic gemini surfactants (where m= 10, 12 and 14) with monomeric surfactants (dodecyltrimethylammonium bromide, tetradecyltrimethylammonium bromide and cetyltrimethylammonium bromide) has been studied in aqueous and in aqueous n-propanol, n-butanol, tertiary butanol, propylene glycol and glycerol solutions using conductivity, surface tension, viscosity and dynamic light scattering techniques at 298.15, 308.15 and 318.15 K, respectively. In mixtures of 10-2-10 with monomeric surfactants, the synergistic interactions increase with the chain length of monomeric surfactants whereas the mixtures with 12-2-12 and 14-2-14 exhibit the opposite trends. However, the synergistic interactions decrease with the increase in temperature of all the mixtures. The thermodynamic and surface parameters have been evaluated and the influence of the variations in hydrophobic chain length of the surfactants and the type of the co-solvent on these parameters has been discussed. The hydrodynamic diameter increases with the chain length of the surfactants. (C) 2015 The Authors. Published by Elsevier B.V. on behalf of King Saud University.

Effects of silica nanoparticle on the solution properties of hydrophobically associating polymer based on acrylamide and beta-cyclodextrin

Synthesis of a novel beta-cyclodextrin-functionalized hydrophobically associating polyacrylamide named ASM was carried out using acrylamide (AM), cetyl dimethyl allyl ammonium bromide (SD-16) and modified beta-cyclodextrin (M-beta-CD) via free-radical copolymerization. Effective characterization methods, including FT-IR, H-1 NMR and TGA, were adopted to evaluate ASM. Influences of SiO2 nanoparticle (nanoSiO(2)) on ASM solution properties were evaluated. The results showed that the addition of nano-SiO2 significantly increased the temperature resistance, salt tolerance and shear resistance of the ASM solution. It was found that ASM/SiO2 composite had 1.5 times higher viscosity than ASM in the range of 25 -90 degrees C. The FT-IR data confirmed that the formation of hydrogen bond between silanol groups at surface of nano-SiO2 and amide group, hydroxyl group of M-beta-CD in ASM molecule contributed to the improved performance. What s more, viscoelastic test indicated that nano-SiO2 remarkably facilitated the crosslinks among polymer molecules and enhanced the elasticity of ASM/SiO2 composite. Based on the enhanced oil recovery tests, the oil recovery could remarkably enhance 10.08% for composite versus only 6.56% for ASM. (C) 2019 Elsevier B.V. All rights reserved.
