First electroanalytical investigation and simple quantification of a thrombopoietin-receptor agonist drug eltrombopag in the presence of cationic surfactant at a non-modified boron-doped diamond electrode

The present study describes the first electroanalytical investigation and the development of a novel voltammetric method for a sensitive, simple, fast, cheap and eco-friendly determination of eltrombopag (ELT). At a borondoped diamond electrode pretreated electrochemically (anodic and subsequent cathodic), the compound presented one or two oxidation steps at relatively low positive potentials within the pH range 6.0-12.0 by employing square-wave voltammetry. The sensitivity of the measurements was significantly enhanced with the positive effect of cetyltrimethylammonium bromide (CTAB) under the accumulation condition. In Britton-Robinson buffer pH 12.0 containing 2 x 10(-4) mol L-1 CTAB (after 30 s accumulation at open-circuit condition), there was a linear dependence of peak current at +0.19 V (vs. Ag/AgCl) and ELT concentration in the range of 0.1-12.5 mu g mL(-1) (2.3 x 10(-7)-2.8 x 10(-5) mol L-1) with a detection limit of 0.0125 mu g mL(-1) (5.7 x 10(-8) mol L-1). The developed approach could be used for ELT determination in commercial tablet formulations.

High-temperature induced iodide and bromide ions filling lattice for high efficient all-inorganic perovskite solar cells

All inorganic CsPbX3 perovskites have gained great attentions owing to their excellent carrier transport property and thermal stability. However, the presence of X vacancy in the CsPbX3 lattice results in a high trap density within CsPbX3 films, and subsequently affects the photovoltaic performance of solar cells. Here, we use phenylethylammonium iodide (PEAL) and phenylethylammonium bromide (PEABr) to manipulate the film quality of inorganic perovskites, which significantly improve the moisture-resistance of the CsPbI2 Br film and photovoltaic performance. It is found that there is no so-called two-dimensional PEA(2)PbI(4) and PEA(2)PbBr(4) materials formed after a high temperature annealing, but iodine or bromide vacancies can be filled by external anions. The improved film quality with a low trap density renders the enhancement of the perovskite phase stability and the device efficiency of the CsPbI2Br solar cells. This work shows that filling vacancies by external anions can promote perovskite photovoltaic performance and stability. (C) 2020 Published by Elsevier B.V.

Phosphatidylethanolamine binding protein 1 enhances sensitivity of gastric cancer cell to 5-fluorouracil via inhibition of cell proliferation, migration and invasion

Purpose: To determine the association between phosphatidylethanolamine binding protein 1, which is an Raf kinase inhibitor protein (RKIP), and 5-fluorouracil (5-FU) via analysis of the association between RKIP and clinical responses in individuals treated using fluorouracil-based chemotherapy. Methods: Human gastric cancer cell lines MGC-803 and SGC-7901 were used in this study. Cell viability was measured using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Apoptosis and migration were determined with flow cytometry and Transwell chamber assays, respectively. The mRNA and protein expressions of apoptosis-related factors were assayed using real-time polymerase chain reaction (RT-PCR) and Western blotting, respectively, while the expression of RKIP was determined by immunohistochemical staining. Results: Chemotherapeutic drug (5-FU) treatment induced low RKIP expression levels in tumorigenic GC cells, thereby sensitizing the cells to apoptosis (8.57 vs 1.25 %, p < 0.01). The highest RKIP level correlated well with initiation of apoptosis (4.20 vs 1.25 %, p < 0.01). Following in vitro downregulation of RKIP, there was increase in the viability and proliferation of RKIP-inhibited cells over time, and these changes were linked to alterations in cell cycle phases and increased optical density in MTT proliferation assay (1.55 vs 1.18, p < 0.01). In vitro Transwell assay measurement revealed an association between RKIP downregulation and enhancement of cell migration potential (652 vs 436, p < 0.01). Ectopic RKIP expression restored the apoptotic sensitivity of resistant cells (14.30 vs 1.36 %, p < 0.01). This sensitization was annulled by upregulation of survival routes. Reduction of RKIP by expression of antisense and siRNA conferred resistance on cancer cells sensitive to 5-FU-mediated apoptosis (6.88 vs 2.13 %, p < 0.01). Conclusion: Thus, RKIP is a promising therapeutic strategy for improving the efficacy of clinically relevant chemotherapeutic drugs for GC.

Tiotropium bromide, a long acting muscarinic receptor antagonist triggers intracellular calcium signalling in the heart

Background and propose: Tiotropium bromide (TB) is a long acting muscarinic receptor antagonist used to manage chronic obstructive pulmonary disease (COPD). Recent meta-analyses suggest an increased risk of cardiovascular events with TB. Ca2+/calmodulin dependent kinase II (CaMKII) and L-type Ca-2+ channels regulate Ca2+ concentrations allowing management of Ca2+ across membranes. Pathological increases in Ca2+ are initially slow and progressive, however once the cytosolic concentration rises > 1-3 mu M from similar to 100 nM, calcium overload occurs and can lead to cell death. Ipratropium bromide, a short acting muscarinic receptor antagonist has previously been found to induce Ca2+ mediated eryptosis. The aim of this study was to investigate the role of Ca2+ in Tiotropium bromide mediated cardiotoxicity. Experimental approach: Isolated Sprague-Dawley rat hearts were perfused with TB (10-0.1 nM) +/- KN-93 (400 nM) or nifedipine (1 nM). Hearts were stained to determine infarct size (%) using triphenyltetrazolium chloride (TTC), or snap frozen to determine p-CaMKII (Thr(286)) expression. Cardiomyocytes were isolated using a modified Langendorff perfusion and enzymatic dissociation before preparation for Fluo 3-AM staining and flow cytometric analysis. Key results: TB increased infarct size compared to controls by 6.91-8.41%, with no effect on haemodynamic function. KN-93/nifedipine with TB showed a 5.90/7.38% decrease in infarct size compared to TB alone, the combined use of KN-93 with TB also showed a significant increase in left ventricular developed pressure whilst nifedipine with TB showed a significant decrease in coronary flow. TB showed a 42.73% increase in p-CaMKII (Thr(286)) versus control, and increased Ca2+ fluorescence by 30.63% in cardiomyocytes. Conclusions and implications: To our knowledge, this is the first pre-clinical study to show that Tiotropium bromide induces Ca2+ signalling via CaMKII and L-type Ca2+ channels to result in cell damage. This has significant clinical impact due to long term use of TB in COPD patients, and warrants assessment of cardiac drug safety.

LncRNA NEAT1 knockdown attenuates autophagy to elevate 5-FU sensitivity in colorectal cancer via targeting miR-34a

Backgrounds Colorectal carcinoma (CRC) is a common malignant tumor. Increasing evidences indicated that CRC showed a resistance to 5-fluorouracil (5-FU) and further resulted in a poor prognosis. In this study, we aim to investigate the effect of long noncoding RNA nuclear paraspeckle assembly transcript 1 (LncRNA NEAT1) on cell viability, sensitivity to 5-FU, and autophagy of CRC cell lines. Methods MTT (3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-Htetrazolium bromide) was used to detect cell viability, immunofluorescent staining was used to detect autophagy puncta, and luciferase reporter system was used to determine binding ability between miR-34a and NEAT1 or putative targets. Additionally, indicated mRNAs and protein expressions were determined by qRT-PCR or western blotting, respectively. Results We found that NEAT1 expression was increased in CRC tissues and cells, which showed a negative correlation with miR-34a expression. In addition, NEAT1 knockdown noticeably inhibited the proliferation of CRC cells and enhanced 5-FU sensitivity. It revealed that NEAT1 knockdown suppressed the LC3 puncta and the expressions of Beclin-1, ULK1, and ratio of LC3II/I. Overexpression of miR-34a showed similar trends with NEAT1 knockdown. miR-34a was validated to target the putative binding sites in 3 ‘-UTR of HMGB1, ATG9A, and ATG4B, which are involved in the activation of autophagy. Inhibition of miR-34a or overexpression of HMGB1 could effectively reverse elevated 5-FU sensitivity upon NEAT1 knockdown. In addition, 3-MA reversed NEAT1 overexpression-induced resistance in HT29 cells. Conclusion These findings indicate that LncRNA NEAT1 could target miR-34a and promote autophagy to facilitate 5-FU chemoresistance in CRC.

Synthesis of poly(phenylene methylenes) via a AlCl3-mediated Friedel-Craft alkylation of multi-substituted benzyl bromide with benzene

A facile AlCl3-mediated Friedel-Craft alkylation between a multi-substituted benzyl bromide and benzene is established, in which a wide set of poly(phenylene methylenes) (MMSs) are synthesized through a two-step strategy under metal-free conditions with high yields (slightly lower than theoretical yields). The resulting MMSs, characterized by Fourier transform infrared spectrometry, nuclear magnetic resonance spectrometry, thermogravimetric analysis, elemental analysis, gel permeation chromatography, UV-vis and fluorescence spectrometry, feature large molecular mass, outstanding fluorescence, and excellent thermal/chemical stabilities. Moreover, a gram-scale reaction was carried out under the standard conditions to produce MMSs, exhibiting a promising potential application in industrial practice. (c) 2019 Wiley Periodicals, Inc. J.

New Concentration Correlations of NaOH Aqueous Solutions for a Thermodynamic Process

Some processes such as air conditioning absorption systems have been developed as a feasible and economical alternative to help reduce the consumption of fossil fuels and prevent the impact of gas emission produced by electrical air conditioning. However, a main disadvantage of these systems is the absorbent’s crystallization phenomenon in the working mixture, which occurs when the absorbent concentration is higher than the saturation point. Among the aqueous working mixtures, NaOH solution shows several advantages for absorption system applications. The aim of this paper is to propose new mathematical correlations to predict or estimate the NaOH concentrations and refractive index in aqueous solutions (H2O NaOH) for an air conditioning absorption system application. The experimental measurements of NaOH concentration and refractive index were made in situ from aqueous solutions with concentrations from 20 to 50% (weight/weight %, with increases of 5%) and temperatures between 10 and 60 C (with increments of 1 C). Two correlations for predicting the concentration of NaOH and refractive index based on cubic regression models with R2 of 0.99704 and 0.99918, respectively, are presented for the first time. The normalized error for NaOH estimation using experimental data lies between 0.026 and 0.040, and for refractive index, the estimation lies between 0.002 and 0.001. Both correlations present a good fit to predict the NaOH concentration between 25 and 45% of concentration ratio.
