BackgroundVoice disorders are a worldwide problem impacting human health, particularly for occupational voice users. Avoidance of surface dehydration is commonly prescribed as a protective factor against the development of dysphonia. The available literature inconclusively supports this practice and a biological mechanism for how surface dehydration of the laryngeal tissue affects voice has not been described. In this study, we used an in vivo male New Zealand white rabbit model to elucidate biological changes based on gene expression within the vocal folds from surface dehydration. Surface dehydration was induced by exposure to low humidity air (18.6% + 4.3%) for 8h. Exposure to moderate humidity (43.0% + 4.3%) served as the control condition. Ilumina-based RNA sequencing was performed and used for transcriptome analysis with validation by RT-qPCR.ResultsThere were 103 statistically significant differentially expressed genes identified through Cuffdiff with 61 genes meeting significance by both false discovery rate and fold change. Functional annotation enrichment and predicted protein interaction mapping showed enrichment of various loci, including cellular stress and inflammatory response, ciliary function, and keratinocyte development. Eight genes were selected for RT-qPCR validation. Matrix metalloproteinase 12 (MMP12) and macrophage cationic peptide 1 (MCP1) were significantly upregulated and an epithelial chloride channel protein (ECCP) was significantly downregulated after surface dehydration by RNA-Seq and RT-qPCR. Suprabasin (SPBN) and zinc activated cationic channel (ZACN) were marginally, but non-significantly down- and upregulated as evidenced by RT-qPCR, respectively.ConclusionsThe data together support the notion that surface dehydration induces physiological changes in the vocal folds and justifies targeted analysis to further explore the underlying biology of compensatory fluid/ion flux and inflammatory mediators in response to airway surface dehydration.

Resorcinarenes are cavity-containing compounds when in the crown conformation, from the calixarene family of concave compounds. These easy to synthesize macrocycles can be decorated at the upper rim through the eight hydroxyl groups and/or the 2-position of the aromatic ring. They are good synthons in supramolecular chemistry leading to appealing assemblies such as open-inclusion complexes, capsules and tubes through multiple weak interactions with various guests. Halogen bonding (XB) is a highly directional non-covalent interaction by an electron-deficient halogen atom as a donor that interacts with a Lewis base, the XB acceptor. This tutorial review provides an overview of recent advances in halogen-bonded assemblies based on resorcinarenes and their derivatives, specifically focusing on discrete and capsular assemblies.

Cardiovascular diseases are among the main causes of mortality in the world. There is evidence of cardiovascular harm after exposure to low lead or mercury concentrations, but the effects of chronic exposure to the association of low doses of these toxic metals are still unknown. This work evaluated after 4 weeks, the association effects of low concentrations of lead and mercury on blood pressure and vascular resistance reactivity. Wistar rats were exposed for 28 days to lead acetate (1st dose of 4 mu g/100 g and subsequent doses of 0.05 mu g /100 g/day to cover daily losses) and mercury chloride (1st dose of 2.17 mu g/kg and subsequent doses of 0.03 mu g/kg/day to cover daily losses) and the control group received saline, i.m. Results showed that treatment increased blood pressure and induced left ventricular hypertrophy. The mesenteric vascular reactivity to phenylephrine and the endothelium-dependent vasodilator response assessed by acetylcholine did not change. Additionally, reduced involvement of vasoconstrictor prostanoids derived from cyclooxygenase was observed in the PbHg group. By other regulatory routes, such as potassium channels, the vessel showed a greater participation of BKCa channels, and a reduction in the participation of K-v channels and SKCa channels. The endothelium-independent smooth muscle relaxation was significantly impaired by reducing cGMP, possibly through the hyperstimulation of Phosphodiesterase-5 (PDE5). Our results suggested that exposure to low doses of lead and mercury triggers this compensatory mechanism, in response to the augment of arterial pressure.

A colour changeable optical sensing membrane was prepared for quantitative detection of Cd(II), Zn(II) and Cu (II) by using polyvinyl chloride membrane containing bis(2-ethylhexyl) phosphate for chemical absorption of chromogenic reagent 1-(2-pyridylazo)-2-naphthol. Under the optimum conditions, the three ions were measured by UV-visible spectrophotometer at lambda max = 547, 554 and 560 nm, respectively. The linear ranges of 8.90 x 10(-9)-8.90 x 10(-4) mol.L-1 [Cd(II)], 1.78 x 10(-9)-1.78 x 10(-4) mol.L-1 [Zn(II)] and 1.78 x 10(-7)-1.78 x 10(-3) mol.L-1 [Cu(II)] and detection limits of 3.89 x 10(-9), 3.42 x 10(-10) and 1.20 x 10(-7) mol.L-1 were obtained, respectively. The response time was between 7 and 15 min. For common anions and cations, the sensing membrane exhibited good selectivity. Selective determination of Cd(II), Zn(II) and Cu(II) was achieved by adding a suitable masking agent. The sensing membrane was regenerated by soaking in nitric acid for 1-3 min and maintained a stable response after three times of reuse. The sensing membrane was successfully used for the determination of Cd(II), Zn(II) and Cu(II) in real samples.

Tin oxide (SnO2) is an emerging electron transport layer (ETL) material in halide perovskite solar cells (PSCs). Among current limitations, open-circuit voltage (V-OC) loss is one of the major factors to be addressed for further improvement. Here a bilayer ETL consisting of two SnO2 nanoparticle layers doped with different amounts of ammonium chloride is proposed. As demonstrated by photoelectron spectroscopy and photophysical studies, the main effect of the novel ETL is to modify the energy level alignment at the SnO2/perovskite interface, which leads to decreased carrier recombination, enhanced electron transfer, and reduced voltage loss. Moreover, X-ray diffraction reveals reduced strain in perovskite layers grown on bilayer ETLs with respect to single-layer ETLs, further contributing to a decrease of carrier recombination processes. Finally, the bilayer approach enables the more reproducible preparation of smooth and pinhole-free ETLs as compared to single-step deposition ETLs. PSCs with the doped bilayer SnO2 ETL demonstrate strongly increased V-OC values of up to 1.21 V with a power conversion efficiency of 21.75% while showing negligible hysteresis and enhanced stability. Moreover, the SnO2 bilayer can be processed at low temperature (70 degrees C), and has therefore a high potential for use in tandem devices or flexible PSCs.

Recent experiments have reported anomalously large screening lengths of interactions between charged surfaces confining concentrated electrolytes and ionic liquids. Termed underscreening, this effect was ascribed to bulk properties of dense ionic systems. Herein, we study bulk ionic screening with extremely large-scale molecular dynamics simulations, allowing us to assess the range of distances relevant to the experiments. Our results yield two screening lengths satisfying distinct scaling relations. However, with an accuracy of 10(-5)k(B)T in interionic potentials of mean force, we find no signs of underscreening, suggesting that other than bulk effects might be at play in the experiments.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 50-84-0, you can contact me at any time and look forward to more communication. Name: 2,4-Dichlorobenzoic acid.

In this paper the corrosion behavior of high temperature corrosion resistant alloys is investigated in a gas atmosphere containing HCl and H2S at 480 degrees C and 680 degrees C. By considering the vapor pressures of the metal chlorides and the water gas shift reaction, as well as the influence of H2S, the different corrosion behavior at 480 degrees C compared to 680 degrees C can be explained and a model of the course of corrosion is proposed. Corrosion tests were performed for 240 h with the austenitic stainless steels S31400 (20 wt% Ni) and N08811 (30.4 wt% Ni) and with the Ni-based alloy N06600 (72.5 wt% Ni). It could be shown that with increasing Ni-content in the alloy, the corrosion rate at high temperatures decreased, but this effect could no longer be observed at lower temperatures. While for N08811 and N06600 the mass loss was lower at 680 degrees C, it increased at temperatures of 480 degrees C. In the case of S31400 the mass loss increased with rising temperature.

The fruit wastes of Mangifera pajang were found to exhibit excellent antioxidant capacity. However, its application can be limited by its poor stability. Therefore, this study aims to improve its stability by solubilizing them in a novel choline chloride/ascorbic acid natural deep eutectic solvent (CHCL/AA NADES) system. The degradation of the antioxidant extracts in the aqueous and NADES system under effects of temperature (25 degrees C, 40 degrees C, 60 degrees Cand 80 degrees C) and pH (3.0-8.0) were studied by modeling the degradation kinetics. For both systems, the degradation process followed the first-order kinetics. Remarkably, a lower degradation rate constant was found for the antioxidant-CHCL/AA NADES system, suggesting the ability of CHCL/AA NADES in protecting the antioxidant against extreme temperature and pH. Moreover, the half-life values for the antioxidant-CHCL/AA NADES was higher by 4.17-25% as compared to the antioxidant-aqueous system, suggesting that the CHCL/AA NADES is feasible to improve the stability of antioxidants.

In order to extract lignin, a novel near-neutral deep eutectic solvent (DES) was developed to treat wheat straw which facilitated its subsequent enzymatic glycation. The DES, whose in situ complexation promotes lignin depolymerization, was composed of choline chloride (ChCl), boric acid (BA), and polyethylene glycol-200 (PEG-200). Our results showed that this kind of DES could dissolve a large amount of lignin and hemicellulose yet retained cellulose well. Under optimum conditions (DES ratio of 1 : 1 : 1.5, 120 degrees C, 4 h), the proportions of lignin and hemicellulose removed amounted to 88.39% and 84.38%, respectively, with enzymatic digestibility reaching 59.3% in the subsequent enzymatic saccharification with a limited timeframe (5 days) and low enzyme load (30 FPU g(-1)). The results also demonstrated that lignin’s removal rate was positively correlated with the amount of BA used in the DES. The 2D-HSQC NMR, FTIR and TG analyses showed the regenerated lignin to be a typical H-G-S type retaining its intact structure (e.g., beta-O-4, beta-beta, beta-5, etc.), whose carbon chain backbone is stable. GPC analysis revealed that this extracted lignin had low molecular weight and a narrower distribution range. Density functional theory showed that BA could bond with -OH similar to Cl-, and it occupied more effective sites than Cl- to break the hydrogen-bonding network between lignin and cellulose. Importantly, the DES can be used multiple times without significantly reducing its efficiency, and its structure and properties remain virtually unchanged throughout the use cycle.
