The neuroprotective effect of MicroRNA-149-5p and coenzymeQ10 by reducing levels of inflammatory cytokines and metalloproteinases following focal brain ischemia in rats

The increase in some factors following cerebral ischemia, especially Matrix metalloproteinase (MMPs) and inflammatory factors lead to blood-brain barrier (BBB) damages, edema and neuronal death. Previous studies have shown that these molecules are miRNA-149-5p (miR-149) and Coenzyme (Co) Q10 targets. Therefore, in this study, the effect of mimic of miRNA-149-5p (mimic miR) and CoQ10 on the expression of metalloproteinase 1 and 2 and inflammatory cytokines following injury caused by cerebral ischemia is investigated. Cerebral ischemia was modeled by Middle Cerebral Artery Occlusion (MCAO). Male Wistar rats were randomly divided into 6 groups: sham (without surgery and treatment), control (MCAO), negative control (NC): MCAO + – scrambled miR, vehicle: MCAO + Ethanole, first treatment: MCAO + mimic miR, second treatment: MCAO + Q10. Each group was divided into 6 subgroups to evaluate neurological defects, the volume of tissue damage using 2,3,5-triphenyl tetrazolium chloride (TTC) staining, blood-brain barrier permeability using cerebral Evans Blue (EB) staining, edema by measuring the percentage of brain water, MMP-2,9 mRNA and miR-149-5p levels using Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) and the levels of IL-6 and TNF-alpha proteins using ELISA. The data obtained from this study showed that the use of mimic miR and Q10 increased the level of miR-149, decreased the extent of neurological defects and tissue damage, increased BBB integrity, decreased brain water percentage and also decreased the level of inflammatory cytokines and MMPs. It seems that the use mimic of miRNA-149-5p and Q10 can have a protective effect on the brain by reducing MMPs and inflammatory factors following cerebral ischemia and this could lead to a new treatment strategy to reduce the complications of cerebral ischemia.

Novel Homogeneous Anion Exchange Membranes for Reproducible and Sensitive Nucleic Acid Detection via Current-Voltage Characteristic Measurement

One-pot synthesis of novel hydrogel-based anion exchange membranes (AEMs), with only a single-phase monomer mixture, was used to eliminate surface heterogeneity and generate reproducible electroconvective microvortices in the over-limiting region of the current-voltage characteristic (CVC) curves. Diallyldimethylammonium chloride (DDA) was used as the main component to provide the cation charge groups, and 2-hydroxyethyl methacrylate (HEMA) and ethylene glycol dimethyl acrylate (EGDMA) were used as the auxiliary structure monomers. The uniform membrane structure allowed reproducible and sensitive DNA detection and quantification, as probe-target surface complexes can gate the ion flux and produce large voltage shifts in the over-limiting region. Suppressed membrane curvature due to controlled swelling is a crucial part to avoid the reduction of depletion region for maintaining the influence of target gene hybridization. Fourier-transform infrared (FTIR) spectroscopy verified the synthesized membrane structure, with a residual vinyl group that allows easy carboxylation via additional photografting reaction. Consequently, a significantly higher DNA probe functionalization efficiency is obtained on the homogeneous AEMs, evidenced by the increasing nitrogen element content and bonding via X-ray photoelectron spectroscopy (XPS). The DDA content was optimized to provide a sufficient coulomb force between AEM and nucleic acid backbone to promote the specific binding efficiency but without high dimensional swelling which might change the surface geometry and restrict the voltage shifting for sensing in the over-limiting region, and the optimal DDA/HEMA ratio was found to be 4/10. The synthesized AEM sensor for recombinant 35S promoter sequence identification exhibited a reproducible calibration standard curve with dynamic range between 30 fM and 1 mu M and high selectivity with only 0.01 V shift for 1 nontarget oligo.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 139631-62-2 is helpful to your research. Name: Cyclopropanesulfonylchloride.

Aqueous solutions of binary ionic liquids: insight into structure, dynamics, and interface properties by molecular dynamics simulations and DFT methods

The behavior of aqueous solutions of mixtures of ionic liquids (ILs) is of special interest because of their amphiphilic character, from both a fundamental and application viewpoint. In this work, we conducted molecular dynamics (MD) simulations and density functional theory (DFT) calculations to understand the effect of water on the intermolecular interactions in three IL binary mixtures [C(4)mim]/[Cl]/[BF4], [C(4)mim]/[Cl]/[PF6] and [C(4)mim]/[BF4]/[PF6] containing the well-characterized cation, 1-n-butyl-3-methylimidazolium [C(4)mim](+) and the anions chloride [Cl](-), tetrafluoroborate [BF4](-), and hexafluorophosphate [PF6](-). The perturbation of the structures in the binary IL mixture by water molecules was analyzed in the bulk and at the liquid/vacuum interface using distribution functions, hydrogen-bond statistics, and density profiles. Interactions between anions and cations change drastically when the IL mixtures are dissolved in water. In particular, anion-water interactions are stronger than anion-cation interactions. H-Bonds are the dominant interactions. They are prevalently electrostatic and strong for the two [Cl]-containing systems in both the water-free and the water-containing systems. The very hydrophobic [C(4)mim]/[BF4]/[PF6] system gains stability from dispersive interactions and consequently segregates water markedly when admixed. The most probable orientations of IL cations in the bulk and at the vicinity of the interface were examined using bivariate distribution calculations and show [PF6](-) segregating to the surface in keeping with its highly hydrophobic nature. DFT calculated structures, energies, dipole moments, global hardness and solvation energies using model ion pairs [C(4)mim][X] or complexes [C(4)mim](2)[X][Y], with [X/Y](-) = [Cl](-), [BF4](-), or [PF6](-) are completely consistent with the findings for the bulk.

Enhanced removal of methylparaben mediated by cobalt/carbon nanotubes (Co/CNTs) activated peroxymonosulfate in chloride-containing water: Reaction kinetics, mechanisms and pathways

Chloride ion (Cl-) widely presents in natural water and wastewater, which can significantly affect the performance of sulfate radical-based advanced oxidation processes (SR-AOPs). However, few studies are available now on the generation of chlorinated by-products in the peroxymonosulfate (PMS) based systems. Here a novel catalyst (cobalt/carbon nanotubes, Co/CNTs) was synthesized and used as a PMS activator to remove methylparaben (MeP) with and without Cl-. The morphology and chemical composition of the fresh and used Co/CNTs were characterized by TEM, SEM, XRD, BET, and XPS. Results revealed that Co/CNTs exhibited significant catalytic activity toward MeP removal, and the removal efficiency increased with the augment of reaction temperature and concentrations of Co/CNTs and PMS. In the absence of CI 83.2% of 10 mu M MeP was degraded within 60 mM by using 2 mg/L Co/CNTs and 100 mu M PMS at 25 degrees C with pH 7.0. However, complete removal of MeP was achieved within 20 mM in the presence of 100 mM Cl-, which enhanced the apparent rate constant by a factor of 4.3. Consequently, TOC removal was enhanced from 8.1% to 19.2% within 60 mM. Through the quenching experiments, both SO4 center dot- and center dot OH were found responsible for MeP degradation without Cl-, while Cl-2(-center dot) was the main reactive oxygen species (ROS) with 100 mM Cl-. Based on the intermediates identified via TOF-LCMS, four potential reaction pathways were proposed, including hydrogen abstraction coupling reaction, hydroxylation, center dot OH attack, and Cl-2(-center dot) attack. The intermediates also exhibited decreased toxicity compared to the parent compound based on the ecotoxicity evaluation. In addition, Co/CNTs + PMS system achieved over 60% MeP removal from real wastewater with elevated PMS concentration, indicating the process applicability. These findings provide valuable information of SR-AOPs to facilitate organic contaminants removal in Cl–containing water.

Construction of well-defined difluoromethylthio-containing amphiphilic homopolymers by RAFT polymerization

A new acrylamide monomer consisting of both difluoromethylthio and isopropylamide moieties, N-3-(difluoromethylthio)propyl-N-(3-(isopropylamino)-3-oxopropyl)acrylamide (DFTP-NIPAM-AM), was firstly synthesized from 3-difluorothiomethyl-1-propylamine via aza-Michael addition reaction followed by amidation with acryloyl chloride. A well-defined fluoropolymer with a relatively narrow molecular weight distribution, poly(DFTP-NIPAM-AM), was obtained via reversible addition-fragmentation chain transfer (RAFT) polymerization using 3-(benzylthiocarbonothioylthio)propanoic acid as chain transfer agent. The thermal property of the poly(DFTP-NIPAM-AM) homopolymer was examined by differential scanning calorimetry (DSC), which indicated that difluoromethylthio moiety has an obvious impact on the glass transition temperature (T-g). The critical micelle concentration (cmc) of poly(DFTP-NIPAM-AM) homopolymer in aqueous solution was determined by fluorescent probe technique. It was found that poly(DFTP-NIPAM-AM) homopolymer could self-assemble into spherical micelles in aqueous solution, which was visualized by transmission electron microscopy (TEM).

Biomass-Derived Nitrogen-Doped Porous Carbons Activated by Magnesium Chloride as Ultrahigh-Performance Supercapacitors

Porous carbons with high capacitive properties derived from biomass have been increasingly studied for supercapacitor applications. In this work, we prepared N-doped porous carbon through a one-pot MgCl2 activation of lotus root flour with urea. A series of lotus root carbons with different physical/chemical properties were synthesized by adjusting precursors and pyrolysis temperatures. The MgCl2 activation could produce abundant micropores and mesoporous channels in nanocarbons, which are beneficial for ions adsorption and diffusion. The addition of urea improved the porosity, specific surface area, and N content in the carbons, which increased the double-layer capacitance and pseudo-capacitance. MgLC-142-800 with best performance was prepared from a mixture of lotus root flour, MgCl2, and urea with the proportion of 1:4:2 at 800 degrees C, exhibiting high specific capacitance (331.80 and 267.63 F g(-1) at 1 A g(-1 )in the three- and two-electrode system, respectively), excellent rate capability (331.78 and 295.45 F g(-1) at 0.5 and 10 A g(-1), respectively), and good durability (98% capacitance retention a ft er 10000 galvanostatic charge/discharge cycles at 10 A g(-1) in the two-electrode system) in 6 M KOH. Additionally, corn- and black soybean-derived porous carbons were prepared to undergo the same procedures, showing excellent capacitive performance as well. Therefore, biomass-derived nanocarbons with the MgCl2 activation strategy show a promising future for application as a supercapacitor.

Synthesis of biocompatible and highly fluorescent N-doped silicon quantum dots from wheat straw and ionic liquids for heavy metal detection and cell imaging

Silane-based precursors for the synthesis of water-dispersible silicon quantum dots (SiQDs) present harmful effects on both researchers and the environment, due to their high toxicity. Though waste wheat straw is an abundant source of natural silicon, its application towards the synthesis of biocompatible SiQDs for metal detection has not yet been explored. In this study, N-doped SiQDs demonstrating uniform spherical morphologies, excellent water dispersity and strong fluorescence emission with a quantum yield of 28.9% were facilely synthesized by using wheat straw (WS) as silicon source and allyl-3-methylimidazolium chloride (AMIMCl) as nitrogen source. The wheat straw based SiQDs (WS-SiQDs) showed linear fluorescence quenching ((F-0-F)/F) with Cr(VI) and Fe(III) concentration in the range of 0-6×10(-4) M. Following immobilization on hydrophilic silica hydrogels, WS-SiQDs@silica hydrogels demonstrated enhanced fluorescence emission which can selectively detect Cr(VI) and Fe (III) to the limits of 142 and 175 nM, respectively. Moreover, cell imaging results reflected thatWS-SiQDs can penetrate the membranes of dental pulp stem cells and react with the nucleuses of the stem cells. The stem cells maintained high viability under the conditions of 24 h incubation and SiQD concentration below 50 mg.L-1, thus indicating low cytotoxicity ofWS-SiQDs. The as-prepared SiQDs demonstrated notable structural and fluorescent properties, therefore representing promising biocompatible fluorescent nanomaterials for metal detection and cell imaging.

Development of a Sustainable Alternative for the Ammoniacal Cyanidation of Copper-Gold Ores Through a Biological Approach

Due to the problems arising from the presence of copper in the gold cyanidation process, including high cyanide consumption and occupation of the activated carbon surface, biological ammoniacal cyanidation was implemented as a resolution. Bacillus megaterium was implemented to produce cyanide and ammonia in nutrient broth and vinasse media. Maximum cyanide concentrations of 29.8 and 47.5 mg/L were produced using 3 g/L glycine in the mentioned media, respectively. Afterward, the Box-Behnken experiment design method was implemented to optimize ammonia biogenesis in vinasse culture, where 1974 mg/L ammonia was synthesized at 13.56 g/L calcium chloride, 7.2 g/L urea, and pH=7.9. Three different strategies, namely: (1) bio-cyanidation, (2) bio-ammoniacal cyanidation, and (3) bio-ammonia pretreatment/bio-cyanidation, were employed to recover gold and copper from a 1% solid pulp. Afterward, using the nutrient broth medium, 49% gold was recovered by the first approach; the second approach extracted 9.2% gold and 33.5% copper, and 77% copper removal and 76% gold recovery were achieved through the third technique. Nutrient broth substitution with vinasse increased the gold recovery to 97% in the third approach. Hence, ammoniacal pretreatment, in combination with bio-cyanidation, is suggested to recover gold from copper-gold ores. In conclusion, the originality of the present work lies first in developing a bacterial culture procedure in which nutrient broth was replaced with vinasse as an industrial byproduct to make the process more eco-friendly. And secondly, in using the biogenic ammonia to leach out copper from the copper-gold ore and prepare it for gold biocyanidation.Graphical Abstract

Lithium-induced overexpression of beta-catenin delays murine palatal shelf elevation by Cdc-42 mediated F-actin remodeling in mesenchymal cells

Background Lithium chloride (LiCl) is widely used for the treatment of manic and other psychotic disorders, but the administration of lithium can result in several congenital defects in the fetus, including cleft palate (Meng, Wang, Torensma, Jw & Bian, 2015) (Szabo, 1970). However, the mechanism of Lithium’s action as a developmental toxicant in palatogenesis is not well known. Methods In this study, hematoxylin-eosin and immunofluorescence staining were employed to evaluate the phenotypes and the expression of related markers in the LiCl-treated mice model. The palatal mesenchymal cells were cultured in vitro, and stimulated with LiCl or SKL2000, and co-treated with CASIN. beta-catenin protein and other cytoskeleton associated markers were evaluated by Western blotting. Results We found that Lithium disrupted palate elevation by increasing the expression of beta-catenin in C57BL/6J mice with the high incidence of cleft palate (62.5%). LiCl disturbed the F-actin responsible for cytoskeletal remodeling in mesenchymal cells, which proved to be essential in generating the elevating force during palatal elevation. Additionally, our Western blotting analysis revealed that the overexpression of beta-catenin resulted in up-regulation of Cdc42, which mediated the downstream F-actin synthesis. Conclusions We concluded the LiCl-induced beta-catenin overexpression delayed murine palatal shelf elevation by disturbing Cdc42 mediated F-actin cytoskeleton synthesis in the palatal mesenchyme.
