Preparation of water-soluble cellulose derivatives using TEMPO radical-mediate doxidation at extended reaction time

Four types of cellulosic samples, including cotton linters, microcrystalline, never-dried sulfite pulp, and viscose, were tested as potential sources to prepare cellulose-based derivatives, able to be used in homogeneous systems. In this way, by employing water as a solvent, can surpass one of the major drawbacks of native cellulose, its recalcitrance towards common solvents. The chosen derivatization procedure implies the chemical oxidation using 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) radical, sodium hypochlorite, and sodium bromide. Following this treatment, each cellulose sample was processed in such a way as to maximize the content of water-soluble fractions. Therefore, for each cellulose type (except viscose), we could isolate three oxidized samples All of these samples were thoroughly characterized using spectral analyses (FT-IR, H-1 NMR, C-13 NMR), content of negatively charged groups, and degree of polymerization. The morphology of the oxidized products has been evaluated by means of scanning electron microscopy (SEM), and crystallinity was assessed by using X-ray diffraction (XRD). The thermal analyses for the pure and oxidized cellulose samples were also performed. The limit of the solubility in water for the oxidized fractions was checked by using a low-voltage electron microscopy (LVEM).

Adsorption of Iodide and Bromide on Au(111) Electrodes from Aprotic Electrolytes: Role of the Solvent

The adsorption of iodide and bromide ions on Au(111) single-crystal electrodes in three organic solvents [propylene carbonate (PC), diglyme (DG), and dimethyl sulfoxide (DMSO)] was studied by differential capacity measurements, cyclic voltammetry (CV), X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy (EIS). The anion adsorption charge in DMSO is approximately half as large as in propylene carbonate and that in water. Quantification of the adsorbed iodide amount from XPS spectra confirms the coverage estimated from the adsorption charge in CVs. As expected, the rate of anion adsorption on Au(111) is higher for I- than for Br- due to better solvation of the latter. The extent of anion adsorption on Au(111) electrode decreases and the corresponding adsorption rate decreases in the solvent order H2O>PC>DG>DMSO. Since the donor number (DN) of the solvent increases in the same order (PCElectric Literature of 2032-35-1, Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products.

A rapid and simple method for the removal of dyes and organophosphorus pesticides from water and soil samples using deep eutectic solvent embedded sponge

A new treatment method using a deep eutectic solvent embedded melamine sponge (DES-MS) was studied for the removal of organic pollutants from water and soil samples. Five organophosphorus pesticides (OPPs) consisting of azinphos-methyl (AZP), parathion-methyl (PRT), fenitrothion (ENT), diazinon (DIZ) and chlorpyrifos (CPF), and two dyes including acid blue 29 (AB29) and malachite green (MG) were used as the model pollutants. DESs were easily prepared from tetrabutylammonium bromide (TBABr) and various fatty acids. The synthesised DESs were loaded into the sponge before being utilized for the removal of the studied pollutants. After the removal, the residual OPPs or dyes in the supernatant was quantified by high performance liquid chromatography or derivative spectrophotometry, respectively. The proposed method was simple, rapid, environmentally friendly and effective with the removal efficiency higher than 70% for various samples. Moreover, the removal of various dyes was successfully achieved with the efficiency greater than 65% under the optimum condition. (C) 2020 Elsevier Ltd. All rights reserved.

The thermal/pH-sensitive drug delivery system encapsulated by PAA based on hollow hybrid nanospheres with two silicon source

The synthesis of drug delivery systems based on hollow mesoporous silica nanoparticles (MSNs) is still a major challenge. In this work, the hollow hybrid MSNs were successfully prepared by cetyltrimethylammonium bromide-directed sol-gel process and one-step hydrothermal treatment process. The hollow hybrid MSNs had hybrid ethane-bridged frameworks with the uniform particle size (250 nm) and mesoporous pore diameter (3.7 nm). The polyacrylic acid (PAA) encapsulated drug delivery system based on hollow hybrid MSNs was prepared by using silanization, surface modification, doxorubicin hydrochloride (DOX) loading, and PAA coating. Drug encapsulation and release behavior at different temperatures and pH were studied by using DOX as a model guest molecule. The results displayed that the modified hollow ethane-bridged MSNs possessed good biocompatibility and excellent thermal/pH-dual-sensitive drug release property. This novel thermal/pH-sensitive drug delivery system based on hollow ethane-bridged MSNs has the advantages of feasible synthesis, no cytotoxicity, and good drug loading capacity, which may have potential applications in the anticancer therapy.

Development of an ammonium chloride-enhanced thermal-assisted-ESI LC-HRMS method for the characterization of chlorinated paraffins

Simultaneous quantification of short-, medium-, and long-chain chlorinated paraffins (CPs) in environmental matrices is challenging and has received much attention from environmental chemists. In this study, ammonium-chloride-enhanced liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS) was developed for the first time to quantify CPs in sediments and aqueous samples. Three ionization sources, including atmospheric pressure chemical ionization (APCI), electrospray ionization (ESI), and thermal-assisted-ESI, were employed to examine the performance of ammonium chloride as the chloride ion supply reagent in comparison with traditional chloride ion supply reagent, dichloromethane. Ammonium chloride can be easily used with reversed-phase liquid chromatography (LC), whereas dichloromethane is not compatible with aqueous LC mobile phase. Furthermore, other anion-supply reagents, such as ammonium formate, ammonium acetate, and ammonium bromide, were also tested. It was concluded that the adducts of the CPs with the anions were reversible and could partially dissociate into deprotonated CP ions. The yield of deprotonated CP ions was associated with the gas-phase basicity of the deprotonated CP ions and the corresponding anions. Furthermore, collision-induced dissociation curves were drawn to quantify the stability of anionic CP adducts. The ammonium-chloride-enhanced LC-HRMS was further employed for identifying CPs in sediment samples and coupled with an online SPE method for detecting CPs in aqueous samples. This study may significantly contribute to the qualification and quantification of CPs in environmental matrices. (C) 2019 Elsevier Ltd. All rights reserved.

Metal-Loaded Carbonated Mesoporous Calcium Silicates: Synthesis, Characterization, and Application for Diclofenac Removal from Water

In this study, we developed a simple synthesis method of carbonated mesoporous calcium silicate (MCS) materials loaded with iron (Fe-MCS), cerium (Ce-MCS), and iron and cerium (FeCe-MCS) using cetyltrimethylammonium bromide as a template. Such materials were characterized by different advanced techniques-X-ray diffraction analysis, nitrogen physisorption measurement, transmission electron microscopy, scanning electron microscopy with energy-dispersive spectroscopy, X-ray photoelectron spectroscopy, and Fourier-transform infrared spectroscopy. They were examined by adsorption isotherms and wet oxidation to explore their maximum adsorption capacity and catalytic activity toward diclofenac (DCF) in solution, respectively. Results indicated that the advantageous properties of metal-loaded MCS samples were relatively similar to pristine MCS, suggesting that the basic properties of carbonated MCS were properly maintained after the loading process. Their specific surface area and total pore volume ranged 468-634 m(2)/g and 0.761.15 cm(3)/g, respectively. The Langmuir maximum adsorption capacity of DCF by the prepared adsorbents followed the increasing order: MCS (11.8 mg/g) < Fe-MCS (13.8 mg/g) < Ce-MCS (14.7 mg/g) < FeCe-MCS (23.7 mg/g). The adsorption mechanism mainly involved pore filling, hydrogen bonding, and pi-pi interaction. The Fe-MCS catalyst exhibited higher DCF degradation efficiency and rate constant under wet oxidation than the other prepared catalysts. Therefore, the MCS loaded with iron can be regarded as a promising adsorbent and potential catalyst for the efficient removal of DCF drug from water media. Interested yet?

Overexpression of miR-129-5p Mitigates Sepsis-Induced Acute Lung Injury by Targeting High Mobility Group Box 1

Background: MicroRNAs are dysregulated in sepsis. Acute lung injury is a progressive syndrome during sepsis. However, the role of miR-129-5p in the development of acute lung injury induced by sepsis remains unclear. Methods: The acute lung injury of sepsis model was established by cecal ligation puncture (CLP)-treated mice and lipopolysaccharide (LPS)-treated murine alveolar epithelial cell line (MLE)-12 cells. The lung injury in vivo was investigated by hematoxylin and eosin staining, terminal dexynucleotidyl transferase (TdT)-mediated dUTP nick end labeling staining, enzyme-linked immunosorbent assay, lung wet-to-dry weight ratio, and myeloperoxidase activity. The lung injury in vitro was evaluated by 3-(4,5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide, flow cytometry, and enzyme-linked immunosorbent assay. The expression levels of miR-129-5p and high mobility group box 1 (HMGB1) were measured by quantitative real-time polymerase chain reaction and Western blot. The association between miR-129-5p and HMGB1 was validated by luciferase assay and RNA immunoprecipitation. Results: The expression of miR-129-5p was decreased in CLP model and LPS-treated MLE-12 cells. Overexpression of miR-129-5p attenuated inflammatory response, apoptosis, lung wet/dry weight ratio, and myeloperoxidase activity induced by CLP surgery in vivo. Moreover, addition of miR-129-5p increased cell viability and suppressed cell apoptosis and inflammatory response in vitro. HMGB1 as a target of miR-129-5p alleviated miR-129-5p emediated injury suppression in LPS-treated MLE-12 cells. Conclusions: miR-129-5p protects against sepsis-induced acute lung injury by decreasing HMGB1 expression, providing new target for sepsis treatment. (C) 2020 Elsevier Inc. All rights reserved.

Liquid crystal-based sensing platform for detection of Pb2+ assisted by DNAzyme and rolling circle amplification

Lead ions (Pb2+) are one of the most widespread heavy metal contaminants that pose detrimental impact on environment and human health. We demonstrate a highly sensitive and specific liquid crystal (LC)-based sensing platform for detecting Pb2+ assisted by DNAzyme and rolling circle amplification (RCA). Magnetic beads (MBs) are functionalized with DNA duplexes of the catalytic strands (DNAzymes) and the substrate strands. In the presence of Pb2+, the substrate strands are disassembled due to activation of the DNAzyme, which allows initiation of DNA RCA on MBs. The amplified DNA strands can disrupt arrangement of octadecy trimethyl ammonium bromide monolayers (OTAB), thereby inducing planar orientation of LC molecules at the interface of aqueous and LCs. Thus, LCs exhibit bright appearance. In contrast, RCA cannot be triggered in the absence of Pb2+. Therefore, LC molecules adopt perpendicular orientation at the interface, which induces the dark morphology of LCs. The limit of detection reaches as low as 16.7 pM. It is an improvement of more than two orders of magnitude compared to that of previously reported LC-based sensing approaches. This approach also shows excellent performance in monitoring Pb2+ in tap water and lake water.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 2032-35-1. The above is the message from the blog manager. SDS of cas: 2032-35-1.

Cytotoxicity Assessment and Apoptosis-related Gene Profiling of Antibody Treated Acute Myeloid Leukemia (AML) and Acute Lymphocytic Leukemia (ALL) Cancerous Cell Lines

Acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) are common acute leukemia in adults and children, respectively. In these malignancies, chemotherapy is the main treatment strategy that fails in many cases and is usually associated with adverse effects on healthy cells. In this regard, the development of new therapies is essential. Monoclonal antibodies directed to the cell surface markers of leukemic blasts may have promising consequences with minimal toxic effects on normal cells. Since cluster of differentiation 45Ra (CD45Ra) and CD123 antigens, two considered surface markers of leukemic blasts in AlVIL and ALL respectively, are overexpressed on AML and ALL blasts, CD34(+) leukemic progenitors, and AML-LSCs in comparison with normal hematopoietic stem cells (HSCs), they were selected to be targeted; using specific monoclonal antibodies. In this project, CD45Ra(+) cells and CD123(+) cells were targeted by anti-CD45Ra and/or anti-CD123 monoclonal antibodies. Cytotoxicity effect and cell death induction was determined by 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide (IVITT) assay and flow cytometry. Changes in the expression profile of MCL1, cMyc, Survivin, Id1, and PIM1 genes were assessed by real-time PCR. Statistical analysis of the results showed effective antibody-mediated cytotoxicity and induction of apoptosis in KG1 alpha (CD45Ra(+)) and Nalm6 (CD123(+)) cell lines. Also, a significant change in the expression level of some of the apoptosis-related genes was observed. According to the results of this study, it can be concluded that an effective targeting of AML and ALL cancerous cell lines can be performed by anti-CD45Ra and anti-CD123 monoclonal antibodies through their effector functions and apoptosis induction.

Statistical optimization of biodiesel production from para rubber seed oil by SO3H-MCM-41 catalyst

The experimental parameters for biodiesel production from para rubber seed oil and methanol using a SO3H-MCM-41 catalyst were optimized statistically. The SO3H-MCM-41 catalyst was synthesized by co-condensation in the presence of tetraethyl orthosilicate, 3-mercaptopropyl (methyl) dimethoxysilane (MPMDS) and cetyl-trimethylammonium bromide. In the last step, the solid catalyst (SH-MCM41) was oxidized by H2O2 to SO3H-MCM-41. The acid capacity of the obtained SO3H-MCM-41 catalyst was quantified by back titration with 0.1 M sodium hydroxide. The physical and chemical properties of the SO3H-MCM-41 were characterized by nitrogen adsorption/desorption, X-ray diffractometry, Fourier transform infrared spectroscopy and thermogravimetric analysis. The effect of varying the catalyst loading (wt.%), reaction time (h) and temperature (degrees C) and molar composition of MPMDS on the biodiesel yield were investigated using a 2(k) factorial design. The optimal conditions to maximize the biodiesel yield, obtained from the response surface analysis using a Box-Behnken design, was a 14.5 wt.% catalyst loading, and a reaction time and temperature of 48 h and 129.6 degrees C. Under these conditions a fatty acid methyl ester (biodiesel) yield of 84% was predicted, and an 83.10 +/- 0.39% yield experimentally obtained. (C) 2015 The Authors.
