Copper(II) complex-loaded castor oil-based nanostructured lipid carriers used against Mycobacterium tuberculosis: Development, characterisation, in vitro and in vivo biological assays

A copper(II) complex-loaded castor oil-based nanostructured lipid carrier was evaluated to enhance the poor water solubility of antimicrobial compounds, improving their biological properties and antimicrobial activity against Mycobacterium tuberculosis. Nanostructured lipid carriers were composed of the castor oil, polyoxyethylene 40 stearate and caprylic/capric triglyceride, poloxamer 407, cetyltrimethylammonium bromide and three different copper(II) complexes. The systems were ultrasonicated at an amplitude of 8% for 20 min and an ice bath was used throughout the procedure. The blank nanostructured lipid carrier (F5) and nanostructured lipid carriers loaded with copper(II) complex 1, 2 and 3 (F5.1, F5.2 and F5.3, respectively) for 45 days presented values of mean diameter, polydispersity index and zeta potential ranging from 186 to 199 nm, 0.14 to 0.2 and 24 to 30 mV, respectively. Atomic force microscopy indicated that the nanostructured lipid carriers were distributed at the nanoscale, corroborating the mean diameter data. Differential scanning calorimetry determined the melting points of the constituents of the nanostructured lipid carriers. The antimicrobial activity of copper(II) complex-loaded F5 against M. tuberculosis H(37)Rv showed better anti-tuberculosis activity than the free complexes. In vivo biological assays of complex-loaded F5 demonstrated reduced toxicity. Our results suggest that nanostructured lipid carriers could be a potential nanotechnological strategy to optimise tuberculosis treatment.

Wafer-Scale Diisopropylammonium Bromide Films for Low-Power Lateral Organic Ferroelectric Capacitors

Organic ferroelectrics, particularly the polymer polyvinylidene fluoride and its copolymer polyvinylidene fluoride-trifluoroethylene, have received much attention owing to their low cost, flexibility, and convenient thin film fabrication. However, development of this outstanding material for electronic applications is significantly impeded by its attributes of large coercive electric fields and poor spontaneous polarization. While the recent breakthroughs reveal that several kinds of molecular ferroelectrics (e.g., diisopropylammonium bromide (DIPAB)) can exhibit excellent properties comparable to inorganic ferroelectrics, it is still difficult to obtain high-quality continuous thin films for ferroelectric devices with high performance. In this work, a simple solution strategy is used for the preparation of large-area high crystallinity or even single-crystal DIPAB films. Subsequently, planar ferroelectric capacitors are developed with large in-plane ferroelectric polarization. These capacitors possess excellent memory function with small operating voltages (1-3 V), and a record remnant polarization of 13 mu C cm(-2) for organic ferroelectric devices. The findings have the potential to pave the way for the substitution of conventional ferroelectric polymers with DIPAB films for future organic ferroelectric devices.

lncRNA CASC2 inhibits lipopolysaccharide-induced acute lung injury via miR-27b/TAB2 axis

Long non-coding RNA (lncRNA) cancer susceptibility candidate 2 (CASC2) has been reported to exert an important role in acute lung injury (ALI). The present study aimed to investigate the potential underlying mechanism of CASC2 in ALI progression. Reverse transcription-quantitative PCR was conducted to examine the expression of CASC2, microRNA (miR/miRNA)-27b and TGF-beta activated kinase 1 and MAP3K7-binding protein 2 (TAB2) in A549 cells. Cell viability and apoptosis were analyzed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and flow cytometry. Enzyme-linked immunosorbent assay was used to measure the levels of inflammatory-related cytokines to assess the inflammatory response, including interleukin-1 beta (IL-1 beta), IL-6 and tumor necrosis factor alpha (TNF-alpha). The binding sites of miR-27b in CASC2 or TAB2 were predicted using LncBase or microT-CDS software, following which dual-luciferase reporter and RNA binding protein immunoprecipitation assays were performed to confirm the target relationship between miR-27b and CASC2 or TAB2. The protein expression of TAB2 was detected by western blotting. The decreased viability, and increased apoptosis and inflammatory responses were attenuated by the accumulation of CASC2 in lipopolysaccharide (LPS)-stimulated A549 cells. CASC2 could directly bind to miR-27b in A549 cells. CASC2 protected A549 cells from LPS-triggered injury by downregulating miR-27b. TAB2 was a target of miR-27b in A549 cells. The influence of miR-27b depletion was reversed by the silencing of TAB2 in an ALI cell model. CASC2 could increase the expression of TAB2 by serving as a competing endogenous RNA of miR-27b in A549 cells. Collectively, the results suggested that CASC2 attenuated LPS-induced injury in the ALI cell model by modulating the miR-27b/TAB2 axis.

Exosomes Derived from Bovine Mammary Epithelial Cells Treated with Transforming Growth Factor-beta 1 Inhibit the Proliferation of Bovine Macrophages

Transforming growth factor (TGF)-beta 1 is a multifunctional cytokine that plays an important role in regulating immune cell proliferation. We speculate that high expression of TGF-beta 1 may affect the immunity of dairy cows. In this study, untreated exosomes (un-exo) derived from an untreated bovine mammary epithelial cell line (MAC-T) and TGF-beta 1-treated exosomes (t-exo) derived from TGF-beta 1-treated MAC-T cells were isolated by ultracentrifugation and identified by electron microscopy and Western blotting. Then, un-exo and t-exo were used to treat a bovine macrophage cell line (BOSMAC), and the proliferative ability of BOSMAC cells was detected by an 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide assay and flow cytometry. The expression and phosphorylation levels of p38 were analyzed by q-PCR and Western blotting. The results showed that both exosome types exhibited the basic characteristics of exosomes. In BOSMAC cells treated with t-exo, significant inhibition of cell proliferation was observed, and the cell cycle progression was inhibited, while no difference was found between the un-exo and control groups. Only treatment with t-exo increased the expression and phosphorylation of p38, and the addition of the p38 inhibitor SB203580 abrogated the inhibition of BOSMAC cell proliferation by t-exo. Our results demonstrated that t-exo inhibited the proliferation of bovine macrophages by stimulating p38 MAPK and might interfere with immunity in dairy cattle. This finding may provide a new strategy for improving immunity and preventing breast-related diseases in dairy cows.

Interleukin-8 gene expression and apoptosis induced by Salmonella Typhimurium in the presence of Bacillus probiotics in the epithelial cell

Aims This study aimed to evaluate the effects of three Bacillus probiotics on Salmonella Typhimurium, and interleukin-8 (IL-8) gene expression in the co-culture of the Bacillus and the pathogen in vitro. Methods and Results Bacillus subtilis, Bacillus indicus and Bacillus coagulans were initially turned to spore and heat-inactivated forms. The cellular damages of the probiotics on the HT-29 cells were investigated individually and in combination with S. Typhimurium using 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and fluorescence assays. To extract cell free supernatants (CFS) of the probiotics, they were cultured in selective media. The inhibitory activity of CFSs were then assayed against the pathogen. The gene expression of IL-8 of the HT-29 cells was evaluated by real-time PCR in all the groups. The results showed that the CFSs of three probiotics could inhibit the growth of S. Typhimurium by more than 50%. Inhibitory effects of B. indicus and B. subtilis CFSs were related to the production of pepsin-sensitive compounds, except B. coagulans in which the high inhibitory effect was due to organic acids. The spores of the three probiotics and the heat-inactivated forms of B. subtilis and B. coagulans could reduce the cytotoxicity of S. Typhimurium. The cell viability also increased applying both forms probiotics against the pathogen. In all co-culture groups, the IL-8 gene expression induced by S. Typhimurium was reduced. Conclusions The three Bacillus probiotics can be considered as proper candidates for the prevention and treatment of S. Typhimurium food poisoning. Significance and Impact of the Study Applying probiotics as live bacteria is universally noted in foods. This study tried to discover the effects of Bacillus probiotics in the form of spore or even heat-killed bacteria against S. Typhimurium and evaluate ratio of IL-8 gene expression in cell culture. The most effective Bacillus probiotic will be recommended. This approach will help to use probiotics as nonvegetative cells in foods to fight gastrointestinal pathogens.

Hydrogen production via steam reforming of glycerol over Rh/gamma-Al2O3 catalysts modified with CeO2, MgO or La2O3

The glycerol steam reforming (GSR) reaction for hydrogen production was investigated over Rh-based catalysts supported on gamma-Al2O3 modified with CeO2, MgO or La2O3. High specific surface area mesoporous supports (Al2O3, CeO2-Al2O3, MgO-Al2O3 and La2O3-Al2O3) were synthesized by the surfactantassisted co-precipitation method using cetyltrimethylammonium bromide (CTAB) as template. Then, highly dispersed Rh-based catalysts were prepared by the wetness impregnation technique. The physicochemical properties of the as-prepared supports and catalysts were investigated by N-2-physisorption, XRD, ICP-AES, CO-chemisorption, TEM, H-2-TPR, CO2-TPD and NH3-TPD measurements. Performance test experiments were carried out in a continuous flow fixed-bed reactor at water-to-glycerol feed ratio (WGFR) of 20:1 (molar), temperatures from 400 degrees C to 750 degrees C, weight hourly space velocity of 50,000 ml g(-1) h(-1) and atmospheric pressure. The stability of all catalysts was also investigated through 12 h time-on-stream (TOS) experiments at 600 degrees C using a WGFR of 9:1. All catalysts were remarkably stable during TOS with total glycerol conversion of =90%, glycerol conversion into gaseous products of =45% and H-2 selectivity of >= 78%. The final H-2 yield for all catalysts was 2.4-2.9 mol H-2/mol glycerol. TEM experiments showed that the carbon formed onto the spent catalysts was amorphous and that sintering was mostly avoided during TOS, helping explain the excellent catalytic stability observed. The unpromoted catalyst seems to be following a different reaction pathway than and the promoted ones that depends strongly on the population and kind of acid and basic sites over its surface.

Optimization of Nazarov Cyclization of 2,4-Dimethyl-1,5-diphenylpenta-1,4-dien-3-one in Deep Eutectic Solvents by a Design of Experiments Approach

The unprecedented Nazarov cyclization of a model divinyl ketone using phosphonium-based Deep Eutectic Solvents as sustainable non-innocent reaction media is described. A two-level full factorial Design of Experiments was conducted for elucidating the effect of the components of the eutectic mixture and optimizing the reaction conditions in terms of temperature, time, and substrate concentration. In the presence of the Deep Eutectic Solvent (DES) triphenylmethylphosphonium bromide/ethylene glycol, it was possible to convert more than 80% of the 2,4-dimethyl-1,5-diphenylpenta-1,4-dien-3-one, with a specific conversion, into the cyclopentenone Nazarov derivative of 62% (16 h, 60 degrees C). For the reactions conducted in the DES triphenylmethylphosphonium bromide/acetic acid, quantitative conversions were obtained with percentages of the Nazarov product above 95% even at 25 degrees C. Surface Responding Analysis of the optimized data furnished a useful tool to determine the best operating conditions leading to quantitative conversion of the starting material, with complete suppression of undesired side-reactions, high yields and selectivity. After optimization, it was possible to convert more than 90% of the model substrate into the desired cyclopentenone with cis percentages up to 77%. Experimental validation of the implemented model confirmed the robustness and the suitability of the procedure, leading to possible further extension to this specific combination of experimental designs to other substrates or even to other synthetic processes of industrial interest.

Solid-State EDLC Device Based on Magnesium Ion-Conducting Biopolymer Composite Membrane Electrolytes: Impedance, Circuit Modeling, Dielectric Properties and Electrochemical Characteristics

The polymer electrolyte based on Dx:Cs:Mg(CH3COO)(2):Ni with three different glycerol concentrations have been prepared. The impedance study has verified that the electrolyte with 42 wt.% of glycerol (A3) has the highest ionic conductivity of 7.71 x 10(-6) S cm(-1) at room temperature. The ionic conductivity is found to be influenced by the transport parameters. From the dielectric analysis, it was shown that the electrolytes in this system obeyed the non-Debye behavior. The A3 electrolyte exhibited a dominancy of ions (t(ion) > t(e)) with a breakdown voltage of 2.08 V. The fabricated electrochemical double layer capacitor (EDLC) achieved the specific capacitance values of 24.46 F/g and 39.68 F/g via the cyclic voltammetry (CV) curve and the charge-discharge profile, respectively. The other significant parameters to evaluate the performance of EDLC have been determined, such as internal resistance (186.80 to 202.27 Omega) energy density (4.46 Wh/kg), power density (500.58 to 558.57 W/kg) and efficiency (92.88%).

EHDAC6 inhibitor WT161 induces apoptosis in retinoblastoma cells and synergistically interacts with cisplatin

Background: WT161 is a recently discovered histone deacetylase 6 (HDAC6) inhibitor which shows anti-tumor effects on multiple myelomas and breast cancer. However, the role of WT161 in retinoblastoma remains unclear. The aim of this study is to explore the role of WT161 in retinoblastoma and its underlying mechanisms. Methods: The anti-proliferation of WT161 on retinoblastoma cells was examined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and soft agar colony formation assay. Cell apoptosis was analyzed using flow cytometer. WT161 and DDP synergistic effect was evaluated by isobologram analysis using CompuSyn software. Results: WT161 suppressed the cell growth and induced apoptosis of retinoblastoma cells in a dose- and time-dependent manner. Mechanistically, WT161 increases the transcription of Bad through activating Bad promoter. Chromatin immunoprecipitation (ChIP) assay showed WT161 treatment increased acetylated histone H3 (AcH3) and acetylated histone H4 (AcH4) on the Bad promoter in retinoblastoma cells. In addition, WT161 shows synergistically inhibitory effects on retinoblastoma cell combined with cisplatin. Conclusions: These results indicate that WT161, as a selective HDAC6 inhibitor, is a promising agent against retinoblastoma.

Widely Tunable, Room Temperature, Single-Mode Lasing Operation from Mixed-Halide Perovskite Thin Films

Solution-processed organic inorganic hybrid perovskites have recently emerged as promising low-cost materials for optoelectronic applications. However, exposure to light or applied bias causes phase separation of mixed-halide perovskites into iodide-rich domains, resulting in the shift of the bandgap energy toward the infrared for light-emitting devices. Proper selection of self-assembled and bulky organoammonium halide additives, 4-fluorobenzylammonium iodide bromide, FPMAI(1-x)Br(x), to the mixed-halide perovskite system, CsxMA(1-x)Pb[I1-xBrx](3) (0 <= x <= 1), exhibits stronger emission and enables stable and low threshold amplified spontaneous emission, which can be tuned over a wide spectral range. Finally, optically pumped surface-emitting distributed feedback lasers operating in a wide spectral range at room temperature are demonstrated for the first time. The laser emission wavelength can be tuned from green to near-infrared by varying the halide stoichiometry in the mixed-halide perovskites. Ultrasmooth mixed-halide perovskites on fused quartz gratings achieve spatially coherent single-mode laser emission with a pump threshold of 4 mu J/cm(2) and less than 0.65 nm full-width at half maximum. The laser device lifetime lasts for up to 42 h (similar to 10(6) laser pulses) under sustained excitation. This work represents a proof-of-concept laser device for practical use in various applications. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
