Cell-Free Culture Broth of Pseudomonas aeruginosa-An Alternative Source of Biodispersant to Synthetic Surfactants for Dyeing the Polyester Fabric

Conventional synthetic dispersants have extensively been used in various textile processes due to their easy availability and cost effectiveness. Nonetheless, due to environmental concerns, researchers are trying to explore ecofriendly dispersants such as biosurfactants as substituents to synthetic surfactants. Currently, biosurfactants are not economical due to the cost of their downstream processing and laborious purification steps. Herein, we employed as-collected cell-free culture broth (CFCB) of a Pseudomonas aeruginosa strain being an indigenous source of rhamnolipid surfactants (as biodispersant) for disperse-dyeing of polyester fabric in comparison with some commercially available synthetic surfactants (such as Triton X-100, cetyltrimethylammonium bromide CTAB and sodium dodecyl sulfate ‘SDS’). The efficiency of biosurfactant-enriched culture broth was compared with that of synthetic surfactants for the said purpose. In addition to conventional testing, dyed fabrics were characterized using scanning electron microscopy (SEM), x-ray diffraction, and surface resistivity analyses. It was observed that the fabric specimen dyed at 1.5% dye concentration on the weight of the fabric (o.w.f.) in the presence of CFCB (containing biosurfactant above-CMC) resulted in excellent tensile and colorfastness properties. The SEM analysis indicated that the dyeing done in the presence of biosurfactant was safer as it did not damage the fabric surface as observed in synthetic dispersants; moreover, the mechanical and color characteristics of dyed fabric were also in the acceptable range.

Antimicrobial Janus Filters that Break Oil-in-Water Emulsions and Separate Oil

Separation of oil from emulsions is industrially important. Existing Janus filters that bear a de-emulsifier on one surface and a hydrophobic polymer on the opposite side can break oil-in-water emulsions and selectively separate the coalesced oil. This paper reports a Janus filter that possesses the additional function of being antimicrobial. This filter is prepared by aero-spraying one side of a cotton fabric with a solution of a copolymer containing the hydrophobic poly(dimethylsiloxane) (PDMS) and soaking the other side in a solution containing a copolymer of dimethylaminoethyl methacrylate (DMAEMA). The fabric is then baked in an oven to cross-link the polymers around the cotton fibers. The DMAEMA-bearing side is further reacted with benzyl bromide to produce quaternized DMAEMA. The latter coalesces oil droplets stabilized by an ionic surfactant most likely via two mechanisms: fusion of different oil droplets around the charged fibers and fusion of overlapping oil droplets adsorbed on the fibers. The adsorption occurs probably due to the displacing of the surfactant molecules on the droplet surfaces by the surfactant-like quaternized DMAEMA units. The coalesced oil is then drawn to the hydrophobic PDMS side that repels water and gets separated from the emulsion. Moreover, the quaternary amine is antimicrobial, killing the model bacterium E. coli under various conditions, and impedes filter contamination by microorganisms. These trifunctional filters with further performance improvement may find practical applications.

Highly Regioselective 5-endo-tet Cyclization of 3,4-Epoxy Amines into 3-Hydroxypyrrolidines Catalyzed by La(OTf)(3)

Highly regioselective intramolecular aminolysis of 3,4-epoxy amines has been achieved. Key features of this reaction are (1) chemoselective activation of epoxides in the presence of unprotected aliphatic amines in the same molecules by a La(OTf)(3) catalyst and (2) excellent regioselectivity for anti-Baldwin 5-endo-tet cyclization. This reaction affords 3-hydroxy-2-alkylpyrrolidines stereospecifically in high yields. DFT calculations revealed that the regioselectivity might be attributed to distortion energies of epoxy amine substrates. The use of this reaction was demonstrated by the first enantioselective synthesis of an antispasmodic agent prifinium bromide.

Promotion of Cellular and Humoral Immunity against Foot-and-Mouth Disease Virus by Immunization with Virus-Like Particles Encapsulated in Monophosphoryl Lipid A and Liposomes

Virus-like particles (VLPs) have emerged as promising vaccine candidates against foot-and-mouth disease (FMD). However, such vaccines provide a relatively low level of protection against FMD virus (FMDV) because of their poor immunogenicity. Therefore, it is necessary to design effective vaccine strategies that induce more potent immunogenicity. In order to investigate the means to improve FMD VLP vaccine (VLPFMDV) immunogenicity, we encapsulated VLPs (MPL/DDA-VLPFMDV) with cationic liposomes based on dimethyldioctadecylammonium bromide (DDA) and/or monophosphoryl lipid A (MPL, TLR4 agonist) as adjuvants. Unlike inactivated whole-cell vaccines, VLPFMDV were successfully encapsulated in this MPL/DDA system. We found that MPL/DDA-VLPFMDV could induce strong cell-mediated immune responses by inducing not only VLP-specific IFN-gamma(+)CD4(+) (Th1), IL-17A(+)CD4(+) (Th17), and IFN-gamma(+)CD8(+) (activated CD8 response) T cells, but also the development of VLP-specific multifunctional CD4(+) and CD8(+) memory T cells co-expressing IFN-gamma, TNF-alpha, and IL-2. In addition, the MPL/DDA-VLPFMDV vaccine markedly induced VLP-specific antibody titers; in particular, the vaccine induced greater Th1-predominant IgG responses than VLPFMDV only and DDA-VLPFMDV. These results are expected to provide important clues for the development of an effective VLPFMDV that can induce cellular and humoral immune responses, and address the limitations seen in current VLP vaccines for various diseases.

Self-supported nickel cobalt carbonate hydroxide nanowires encapsulated cathodically expanded graphite paper for supercapacitor electrodes

The self-standing electrode materials with large surface area and high electronic conductivity have attracted intensive attention in energy storage devices. Herein, the expanded graphite paper (EGP) is fabricated via a controlled cathodic expansion in acetonitrile with tetrabutylammonium bromide at 10 V. The as-prepared EGP exhibits a three-dimensional porous structure with large specific surface area and high electronic conductivity, which is a favorable support for in situ growing nickel cobalt carbonate hydroxide (NiCo-CH) nanowires via a simple hydrothermal method. The as-prepared NiCo-CH@EGP composite achieves high areal capacity of 2.55 C cm(-2) at 0.5 mA cm(-2), and still remains 1.38 C cm(-2) even at 60 mA cm(-2) . The assembled NiCo-CH@EGP//activated carbon asymmetric supercapacitor exhibits the maximum energy density of 0.30 mWh cm(-2) at a power density of 0.92 mW cm(-2) , and a suitable cyclic stability with the capacity retention of 78.1 % after 10,000 cycles at 20 mA cm(-2). The results indicate that the self-standing NiCo-CH@EGP is a potential electrode material for energy storage devices. (C) 2020 Elsevier Ltd. All rights reserved.

MicroRNA-296 functions as a tumor suppressor in breast cancer by targeting FGFR1 and regulating the Wnt/beta-catenin signaling pathway

OBJECTIVE: Breast cancer (BC) is a common malignancy all over the world. However, the detailed mechanism underlying BC progression remains incompletely understood. MicroRNAs (miRNAs) have been observed to play crucial roles in tumorigenesis. The present study aimed to determine the expression and function of miR-296 in BC. PATIENTS AND METHODS: MiR-296 expressions in BC tissue samples and cell lines were examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). After that, we performed functional assays, including MTT (3-(4,5-dimethyl thiazol-2-yl)-2.5-diphenyl tetrazolium bromide) assays and transwell assays, to show the functions of miR-296 in BC cell proliferation, invasion and migration. Immunological histological chemistry (INC) assays were carried out to detect the expression levels of fibroblast growth factor receptor 1 (FGFR1) in BC tissue samples. Western blot was used to explore potential mechanisms of miR-296 in regulating BC progression. A Luciferase reporter assay was carried out to confirm the target gene of miR-296. RESULTS: Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) results demonstrated a significant decrease of miR-296 expressions in BC when compared to the corresponding normal controls. In addition, the decreased miR-296 was correlated with the malignant phenotypes and poorer prognosis of BC patients. The functional assays indicated that miR-296 restoration could repress the proliferation, invasion and migration abilities of BC cells. Moreover, the results of the current study revealed that miR-296 exerted the repressive functions in BC cells via regulating FGFR1, the Wnt/beta-catenin signaling pathway and EMT. Additionally, miR-296 up-regulation could inhibit in vivo BC cell growth. CONCLUSIONS: All these findings indicated that miR-296 exerted anti-BC functions, providing novel therapeutic strategies in BC treatment.

Cytotoxic activity of methanolic fractions of different Marrubium spp. against melanoma cells is independent of antioxidant activity and total phenolic content

The Marrubium genus (horehound) has proved to be an abundant source of biologically active compounds, but there is little knowledge about its potential anticancer activity. Moreover, some Marrubium species have not been the subject of study in this regard. In this study, we performed comparative analysis of phenolic acid (PhA) content and total phenolic content in fractions obtained from methanolic extracts of Marrubium vulgare L. (common horehound), Marrubium cylleneum Boiss. & Heldr. and Marrubium friwaldskyanum Boiss herbs. We examined the cytotoxicity of these fractions against a human melanoma cancer cell line (A375) and normal human skin fibroblasts (BJ) using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide test, cell cycle analysis and real-time monitoring of cell viability. We detected caffeic, p-coumaric, ferulic and gentisic acids among the PhAs. Although the extracts obtained demonstrated low total phenolic content and did not show significant antioxidative properties, the nonhydrolyzed PhA fraction exhibited cytotoxic activity against a human melanoma cancer cell line, without affecting normal fibroblasts. Both acidic and alkaline hydrolysis abolished this activity, indicating that the esterified forms of phenolic compounds caused the observed cytotoxic effects. Further investigation of these compounds may facilitate the development of novel drugs for cancer treatment.

Fluoride varnish containing chitosan demonstrated sustained fluoride release

Fluoride varnish is a professionally applied product that prevents dental caries. However, fluoride varnishes do not provide sustained fluoride release. The objective of this study was to prepare fluoride varnish formulations containing various amounts of chitosan that would generate sustained fluoride release. We evaluated their chemical structure, viscosity, and in vitro fluoride release. Furthermore, the 3-(4, 5-dimethylthiazolyl-2)-2,5diphenyltetrazolium bromide (MTT) assay and direct contact test were used to determine varnish cytotoxicity. We found that all fluoride varnish formulations had the same chemical structure. Their viscosity demonstrated a chitosan concentration-dependent increase. In vitro fluoride release showed a sustained fluoride release. The chitosan fluoride varnishes were cytotoxic to human gingival fibroblasts. We propose the new fluoride varnish formulation as a potential material to be used as a sustained release fluoride varnish.

microRNA-25 promotes cardiomyocytes proliferation and migration via targeting Bim

microRNAs (miRNAs) are pleiotropic players in cardiac development. Recent evidence have suggested miRNAs as promisingly therapeutic targets for cardiac regeneration. This study aimed to reveal the potential effects of miR-25 on cardiomyocytes proliferation and migration. Sprague-Dawley rats received left coronary occlusion surgery to induce an in vivo model of myocardial ischemia/reperfusion (I/R) injury. Expression changes of miR-25 and Bim were tested by quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blot. Besides, primary neonatal and adult cardiomyocytes were transfected by the antisense oligonucleotides or mimic specific for miR-25, and then 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT), 5-ethynyl-2′-deoxyuridine (EdU), Boyden chamber, and terminal-deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) assay were respectively used to determine cardiomyocytes growth and migration. Binding effects of miR-25 on the 3′-untranslated region (3′-UTR) of Bim was assessed by dual-luciferase reporter assay. We found that miR-25 was low expressed, whereas Bim was highly expressed in I/R injury model and hypoxia-stimulated cardiomyocytes. Downregulation of miR-25 in neonatal and adult cardiomyocytes markedly reduced cell proliferation and migration, but promoted apoptosis. Consistently, downregulation of miR-25 decreased the expression of cyclin E2, cyclin D1, and CDK4, and increased the expression of p57 (KIP2) in cardiomyocytes. We additionally found that Bim was a target of miR-25. The inhibitory effects of miR-25 downregulation on cardiomyocytes survival and migration were all significantly attenuated when Bim was silenced. To sum up, our study demonstrates that miR-25 downregulation inhibits cardiomyocytes proliferation and migration, but promotes apoptosis. The role of miR-25 in cardiomyocytes was by targeting Bim.
