A Novel Double-Network, Self-Healing Hydrogel Based on Hydrogen Bonding and Hydrophobic Effect

In this paper, acrylamide is used as a hydrophilic monomer, and octadecyl methacrylate (C18) and polyurethane (PU) monomers are used as hydrophobic monomers. In an aqueous solution containing mixed surfactants of cetyl trimethylammonium bromide and sodium dodecyl sulfate, a series of composite physical hydrogels with dual network structures are synthesized using these three monomers through in situ micelle copolymerization. The results indicate that, with the increase in PU content (<0.08 g), the thermal stability and mechanical properties (stretching and compressive) of the composite gel are enhanced, while the swelling performance becomes poorer. Furthermore, it can heal at room temperature and the self-healing property approaches 88% of that of the original sample after 60 min. Additionally, the self-healing efficiency shows a downward trend with the increase in the amount of PU, which is mainly related to the recovery efficiency of the network chain (polyacrylamide (PAAM) chain and PU chain) and the decrease in the mobility of C18. By constructing the double-crosslinked network, the design and preparation of polymer hydrogels with high stretching capability, good elasticity and self-healing performance provides a new approach to preparing hydrogels with excellent properties. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

PLCG2 promotes hepatocyte proliferation in vitro via NF-kappa B and ERK pathway by targeting bcl2, myc and ccnd1

Phospholipase C gamma 2 (PLCG2) has been implicated in the regulation of cell proliferation, transformation, and tumor growth. In this study, we investigate the mechanism of PLCG2 action using a short interference RNA (siRNA) method. The effects of PLCG2 on rat liver BRL-3A cells treated siRNA were studied by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT assay), bromodeoxyuridine (BrdU) labelling assay, flow cytometry method (FCM), quantitative real-time polymerase chain reaction (qRT-PCR) and western blot. The results showed when PLCG2 was reduced, cell vitality and proliferation rate were significantly decreased (p < .05 vs. control). FCM analysis showed that the number of cell division phase (G2 + M) was declined (p < .05 vs. control). RT-PCR and western blot revealed that the expression of signalling related genes NF-kappa B, FOS, JUN and ELK, target genes BCL2, CCNB1 and CCND1 were remarkably down-regulated in cells treated with PLCG2 siRNAs. Based on these results, we conclude PLCG2 plays an important role in rat liver cell proliferation via ERK and NF-kappa B pathway by regulating the expression of BCl2, MYC and CCND1. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

Manganese(II) in Tetrahedral Halide Environment: Factors Governing Bright Green Luminescence

Finding narrow-band light emitters for the visible spectral region remains an immense challenge. Such phosphors are in great demand for solid-state lighting and display application. In this context, green luminescence from tetrahedrally coordinated Mn(II) is an attractive research direction. While the oxide-ligand environment had been studied for decades, much less systematic efforts have been undertaken with regard to halide coordination, especially in the form of fully inorganic halide matrixes. In this study, we synthesized a series of hybrid organic-inorganic Mn(II) halides as well as a range of fully inorganic Zn halide hosts (chlorides, bromides, iodides) doped with Mn(II). In the latter, tetrahedral coordination is attained via substitutional doping owing to the tetrahedral symmetry of Zn sites. We find that the choice of the halide as well as subtle details of the crystal structure profoundly govern the photoluminescence peak positions (500-550 nm range) and emission line widths (40-60 nm) as well as radiative lifetimes (shorter for iodides) through the altered ligand-field effects and degrees of spin-orbit coupling. The photoluminescence quantum yields were as high as 70-90%. The major hurdle for the practical use of these compounds lies in their low absorption coefficients in the blue spectral regions.

Structural, morphological, luminescent and magnetic studies of CTAB and TOPO assisted Gd2O3:Eu phosphors synthesized via co-precipitation route

Herein, we reported the effect of the surfactants on the structural, morphological, luminescent and magnetic properties of Gd2O3:Eu phosphors synthesized via co-precipitation routes. Trioctylphosphine oxide (TOPO) and cetyltrimethylammonium bromide (CTAB) were used as surfactants in different molar ratios during synthesis. The concentration of the Eu ions was fixed 4 mol% to avoid the variation due to concentration quenching. The structural, morphological, optical and magnetic properties of synthesized phosphors were studied by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), UV-Visible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FTIR), photo-luminescence (PL) spectroscopy, and vibrating sample magnetometer (VSM), respectively. It was observed that the addition of CTAB and TOPO during synthesis had a significant effect on the morphological features. The crystal structure of the synthesized phosphors remained the same even after the addition of surfactants. In addition, the introduction of the surfactants not only influenced the morphology but had remarkable effects on the luminescent and magnetic properties. The significant enhancement in the luminescent and magnetic properties was observed in the case of TOPO assisted samples due to improved crystallinity, defect-free surface and uniform morphology. The results indicated that surfactant concentration also had a significant effect on the morphological, optical and magnetic properties. (C) 2020 Elsevier B.V. All rights reserved.

Influence of the use of surfactants in the treatment of produced water by ceramic membranes

Surfactant-enhanced oil recovery is a method used to augment residual oil extraction from reservoirsHowever, this kind of procedure can produce stable emulsions of water/oil and oil/water, making the conventional treatment of the produced water more difficult. This study evaluates the performance of ultrafiltration process using ceramic membranes for produced water treatment containing the cationic surfactant Dodecyltrimethylammonium bromide (DTAB). To better understand the process, the effect of DTAB and sodium chloride (NaCl) on interfacial properties of oil/water and oil/water/membrane, such as surface tension, membrane wetting, zeta potential and adhesion map were investigated. It was observed that the surfactant facilitates the oil phase adhesion to the membrane surface, causing a permeate flux reduction. On the other hand, the presence of NaCl in the oily emulsion containing DTAB lead to a permeate flux increase, which indicated that ionic strength modifies the interaction between the oil phase and the membrane surface. Considering the high salinity of the produced water, it is possible to imply that the presence of surfactant can contribute to treatment by ultrafiltration process. Independent of surfactant presence in produced water, the oil and grease (COG) content in the permeate stream was consistently lower than 5 mg/L.

Toxicity comparison of three imidazolium bromide ionic liquids to soil microorganisms

Ionic liquids (ILs) are extensively used in several chemistry fields. And research about the effects of ILs on soil microbes is needed. In this study, brown soil was exposed to 1-butyl-3-methylimidazolium bromide ([C(4)mim]Br), 1-hexyl-3-methylimidazolium bromide ([C(6)mim]Br) and 1-decyl-3-methylimidazolium bromide ([C(10)mim]Br). The toxicities of the three ILs are evaluated by measuring the soil culturable microbial number, enzyme activity, microbial diversity and, abundance of the ammonia monooxygenase (amoA) genes of ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA). Results showed that all tested ILs caused a decrease in culturable microbial abundance. Tested ILs exposure inhibit urease activity and promote acid phosphatase and beta-glucosidase activities. Tested ILs reduced soil microbial diversity and the abundances of AOB-amoA and AOA-amoA genes significantly. After a comparison of the integrated biomarker response (IBR) index, the toxicities of tested ILs to soil microorganisms were as follows: [C(10)mim]Br > [C(6)mim]Br > [C(4)mim]Br. Among all collected biomarkers, the abundance of the AOA-amoA gene was the most sensitive one and was easily affected after ILs exposure. (C) 2019 Elsevier Ltd. All rights reserved.

From Proteomics to Personalized Medicine: The Importance of Isoflavone Dose and Estrogen Receptor Status in Breast Cancer Cells

Continuing efforts are directed towards finding alternative breast cancer chemotherapeutics, with improved safety and efficacy profiles. Soy isoflavones represent promising agents but, despite extensive research, limited information exists regarding their impact on the breast cancer cell proteome. The purpose of this study was to compare the proteomic profiles of MCF-7 (estrogen responsive) and MDA-MB-231 (estrogen non-responsive) breast cancer cells exposed to different concentrations of genistein, daidzein, and a soy seed extract, using a high throughput LC-UDMSE protein profiling approach. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay confirmed the dual activity of soy isoflavones on MCF-7 cells and the inhibitory effect on MDA-MB-231 cells. Proteome profiling of paramagnetic beads prepared peptides by nano-LC UDMSE and pathway enrichment analysis revealed that isoflavones affected distinct molecular pathways in MCF-7 and MDA-MB-231 cells, such as tyrosine kinases signaling pathway, cytoskeleton organization, lipid and phospholipid catabolism, extracellular matrix degradation and mRNA splicing. Also, in MCF-7 cells, low and high isoflavone doses induced different changes of the proteome, including cell cycle alterations. Therefore, the expression of estrogen receptors and the isoflavone dose are determinant factors for the molecular impact of isoflavones and must be taken into account when considering adjuvant breast cancer therapy towards personalized medicine.

Effect of topical ophthalmic instillation of rocuronium bromide on the intraocular pressure of kestrels (Falco tinnunculus) and little owls (Athene noctuae)

OBJECTIVE To assess the effect of rocuronium bromide-induced mydriasis on the intraocular pressure (IOP) of kestrels (Falco tinnunculus) and little owls (Athene noctuae). ANIMALS 13 adult kestrels and 13 adult little owls. PROCEDURES All birds were ophthalmologically normal. During the first of 2 treatment periods, a 1% rocuronium bromide solution was topically instilled in both eyes of all birds at a dose of 0.12 mg (12 mu L) for kestrels and 0.20 mg (20 mu L) for little owls. No ophthalmic treatments were administered during the second (control) treatment period, which was conducted 1 week after the first. During both treatment periods, rebound tonometry was used to measure IOP before rocuronium bromide instillation or at the beginning of the control period (baseline) and at predetermined times after baseline or until the pupillary light reflex returned to normal. All IOP measurements were obtained between 8 am and 5 pm. RESULTS The mean IOP did not differ significantly from baseline for either species during the control treatment period. During the rocuronium bromide treatment period, complete mydriasis was achieved in all birds. The mean IOP was significantly decreased from baseline and from the corresponding mean IOP for the control period beginning 60 and 30 minutes after drug instillation for kestrels and owls, respectively, and reached its nadir at 60 minutes after drug instillation for both species. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that topical instillation of rocuronium bromide in the eyes successfully induced mydriasis and decreased the IOP of common kestrels and little owls.

Quantitative Structure-Cytotoxicity Relationship of 2-Arylazolylchromones and 2-Triazolylchromones

Background/Aim: 4H-1-Benzopyran-4-one (chromone), present in various flavonoids as a backbone structure, has been used for the synthesis of anticancer drugs. The study aimed at investigating the cytotoxicity of eight 2-arylazolylchromones and twelve 2-triazolylchromones against four human oral squamous cell carcinoma (OSCC) cell lines and three human normal mesenchymal oral cells, and then performed a quantitative structure-activity relationship (QSAR) analysis. Materials and Methods: Cell viability was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide method. The distribution of cells to various phases of cell cycle was determined by cell cycle analysis. A total of 3,218 physicochemical, structural and quantum chemical features were calculated for QSAR analysis from the most stabilized structure optimized using CORINA. Results: 2-[4-(4-fluorophenyl)-1H-imidazol-1-yl]-4H-1-benzopyran-4-one [6] had the highest tumor-specificity (TS), comparable with that of 5-flurouracil (5-FU) and doxorubicin, inducing cytostatic growth inhibition, accumulation of G(2)+M phase cells with no cells in the G(1) phase. All eight 2-triazolylchromones showed much lower tumor-specificity, confirming our previous finding. Tumor-specificity was also correlated with 3D shape, topological shape, size, ionization potential, and the presence of more than two aromatic rings in the molecule and imidazole ring in the nitrogen-containing heterocyclic ring. Conclusion: [6] can be a lead compound for designing anticancer drugs.
