Microbial carbon use efficiency during plant residue decomposition: Integrating multi-enzyme stoichiometry and C balance approach

Accurate estimation of microbial carbon use efficiency (CUE) in soil is challenged by a high degree of genetic and environmental variability. Different methods vary in their estimates of soil microbial CUE giving the room to select the optimal method for a specific research task, while integrating different methods could improve our understanding of processes controlling CUE variability. Aiming to estimate CUE during plant residue decomposition in different soils, we applied the conventional C-balance method, single C-cycling enzymatic stoichiometry (SCE-STM) and newly proposed multi-C-cycling enzymatic stoichiometry (MCE-STM) methods. The STM approach derives CUE from elemental ratios of microbial biomass, substrate, and activities of C and nutrient (e.g. N) acquiring exoenzymes. The extended MCE-STM is a modification of the SCE-STM method, where we used the sum of three C-cycling enzymatic activities (beta-glucosidase (BGL), beta-D-cellobiohydrolase (BCL), beta-xylosidase (BXL)) as proxy for CUE calculation, instead of using a single C-acquiring enzyme (BGL). We hypothesized that MCE-STM provides a more reliable estimation of microbial CUE in soils amended with complex plant residues than the SCE-STM or the C balance approach. The comparison of methods was done in a laboratory incubation experiment, using two soils differing mainly in acidity level mixed with two specimen of plant residues differing in lignin (L) and polyphenol (PP) content. We anticipated a higher microbial CUE in less acidic (pH 5.1) soil amended with higher quality (lower (L + PP)/N) ratio)) plant residues than in more acidic (pH 4.3) soils amended with medium quality (higher (L + PP)/N ratio) plant residues, due to less energy investment in microbial metabolism in the former case. Microbial CUE estimations were completed at 7, 15, 30, 45 and 60 days. Lower CUE values (0.09-0.18) were recorded by MCE-STM as compare to those (0.24-0.47) obtained by C-balance and SCE-STM methods. Irrespective of applied CUE estimation methods, higher CUE was recorded in less acidic (pH 5.1) soil amended with residues of higher quality than the other three combinations. Microorganisms invested more energy to support growth in low pH soil in order to tolerate soil acidity, which, in turn, suppressed N-acquiring enzymatic activity and further decreased CUE. The modification of the MCE-STM method for CUE determination proposed in this work was capable to quantify the combined effect of soil pH and plant residue quality on efficiency of microbial metabolism. It, therefore, can be considered as viable alternative to the original stoichiometric modeling approach (SCE-STM).

Chondroitin sulfate as a green corrosion inhibitor for zinc in 26% ammonium chloride solution: Electrochemical and surface morphological analysis

In the present investigation, Chondroitin sulfate (CS) has been tested as green as a corrosion inhibitor for zinc carbon battery by using electrochemical impedance spectroscopy (EIS), electrochemical frequency trend modulation (EFTM) and potentiodynamic polarization (PDP) measurements. The calculated results suggest that inhibition efficiency is 98.9% at the optimum concentration (200 mg/L) in 26% NH4Cl solution at 308 K. The outcome of EIS indicates that the values of double-layer thickness increased as the CS concentration increased. EFTM suggests in the presence of CS corrosion rate and corrosion current decreased.PDP results reveal that the nature of CS adsorption is mixed with dominantly cathodic.CS adsorption on the zinc surface obeyed the ElA-wady adsorption isotherm model. The magnitude of Delta G(ads) supports the chemical nature of CS adsorption. The Scanning electron microscope (SEM), Energy dispersive X-ray spectroscopy (EDX), and X-ray photoelectron spectroscopy (XPS) study supports the presence of CS adsorbed film over the zinc surface.

Enhanced efficiency and stability in Sn-based perovskite solar cells with secondary crystallization growth

The conversion efficiencies reported for Tin (Sn) halide-based perovskite solar cells (PSCs) fall a large gap behind those of lead halide-based PSCs, mainly because of poor film quality of the former. Here we report an efficient strategy based on a simple secondary crystallization growth (SCG) technique to improve film quality for tin halide-based PSCs by applying a series of functional amine chlorides on the perovskite surface. They were discovered to enhance the film crystallinity and suppress the oxidation of Sn2+ remarkably, hence reduce trap state density and non-irradiative recombination in the absorber films. Furthermore, the SCG film holds the band levels matching better with carrier transport layers and herein favoring charge extraction at the device interfaces. Consequently, a champion device efficiency of 8.07% was achieved along with significant enhancements in V-oc and J(sc), in contrast to 5.35% of the control device value. Moreover, the SCG film-based devices also exhibit superior stability comparing with the control one. This work explicitly paves a novel and general strategy for developing high performance lead-free PSCs. (C) 2020 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.

Enhancement of curcumin solubility by some choline chloride-based deep eutectic solvents at different temperatures

Curcumin (CUR) is a biologically active substance and a natural antioxidant, but it is almost insoluble in water and has low bioavailability. A possible solution to this barrier could be to use solvents that exhibit low toxicity and are biodegradable. Choline chloride-based deep eutectic solvents (DESs) can be used as a co-solvent to increase the solubility of curcumin. The objectives of this study are to introduce and prepare DESs, to measure the solubility of CUR in water and DESs as well as in water-DES mixtures with different weight fractions. In this perspective, the solubility of CUR is measured in the mixtures of water with some DESs based on choline chloride (ChCl) and in pure solvents at T = 298.15 K to 318.15 K. The measured solubility data were correlated by the activity coefficients models e-NRTL and UNIQUAC. Finally, the apparent thermodynamic functions entropy, enthalpy, and Gibbs free energy were estimated for dissolution process using van’t Hoff equation. (C) 2020 Elsevier B.V. All rights reserved.

Co-orchestration of acute kidney injury and non-kidney organ failures in critically ill patients with cirrhosis

Background & Aims Little is known on the course of acute kidney injury (AKI) and its relation to non-kidney organ failures and mortality in critically ill patients with cirrhosis (CICs). Methods We conducted a large prospective, single-centre, observational study in which CICs were followed up daily, during the first 7 days of intensive care, collecting prespecified criteria for AKI, extrarenal extrahepatic organ failures (ERH-OFs) and systemic inflammatory response syndrome (SIRS). Results A total of 291 patients admitted to ICU were enrolled; 231 (79.4%) had at least one ERH-OFs, 168 (58%) had AKI at presentation, and 145 (49.8%) died by 28 days. At day seven relative to baseline, 151 (51.8%) patients had progressive or persistent AKI, while the rest remained free of AKI or had AKI improvement. The 28-day mortality rate was higher among patients with progressive/persistent AKI (74.2% vs 23.5%; P < .001) or maximum stage 3 of AKI in the first week. Two-level mixed logistic regression modelling identified independent baseline risk factors for progressive/persistent AKI, including 3 to 4 SIRS criteria, infections due to multidrug-resistant bacteria (MDR), elevated serum bilirubin, and number of ERH-OFs. Follow-up risk factors included increases in bilirubin and chloride levels, and new development of 2 or 3 ERH-OFs. Conclusions Our results show that among CICs admitted to the ICU, the stage and course of AKI in the first week determines outcomes. Strategies combating MDR infections, multiorgan failure, liver failure and intense systemic inflammation could prevent AKI progression or persistence in CICs. Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 85-54-1.

Design and synthesis of base-metal nickel(II) based catalysts: studies on nearly selective formation of 1-butene from ethylene

A new family of base-metal nickel complexes [Ni(L1-10)(2)] (1-10) were synthesized from tridentate meridional ligands (LH)-H-1 to (LH)-H-10 (where H stands for dissociable proton). Different spectroscopic studies were utilized for the characterization of these complexes [Ni(L1-10)(2)] (1-10). Molecular structures of complexes [Ni(L-1)(2)] (1), [Ni(L-3)(2)] (3) and [Ni(L-8)(2)] (8) were determined by X-ray crystallography. Electronic properties of complexes [Ni(L-1)(2)] (1) [Ni(L-3)(2)] (3) and [Ni(L-8)(2)] (8) were elucidated with the help of DFT and TD-DFT calculations. Complexes [Ni(L1-10)(2)] (1-10) were utilized as catalysts for the synthesis of 1-butene from ethylene using diethyl aluminium chloride as a co-catalyst. A nearly selective formation of 1-butene was observed and productivity up to 17.50 [kg (product/gm catalyst)] h(-1) bar(-1) was found after examining the catalytic activity of complexes 1-10 . A reaction pathway was also proposed for the conversion of ethylene to 1-butene. (C) 2020 Elsevier B.V. All rights reserved.

Pentoxifylline Sensitizes Cisplatin-Resistant Human Cervical Cancer Cells to Cisplatin Treatment: Involvement of Mitochondrial and NF-Kappa B Pathways

Background Cervical cancer continues to be a major public health problem worldwide, and Cisplatin is used as first-line chemotherapy for this cancer; however, malignant cells exposed to CISplatin (CIS) become insensitive to the effects of this drug. PenToXifylline (PTX) is a xanthine that sensitizes several types of tumor cells to apoptosis induced by antitumor drugs, such as Adriamycin, Carboplatin, and CIS. The effects of PTX on tumor cells have been related to the disruption of the NF-kappa B pathway, thus preventing the activation of cell survival mechanisms such as the expression of anti-apoptotic genes, the secretion of proinflammatory interleukins, and growth factors. Objective In this work, we studied the antitumor proprieties of PTX in human SiHa cervical carcinoma cells resistant to CIS. Materials and Methods SiHa and HeLa cervical cancer cells and their CIS-resistant derived cell lines (SiHaCIS-R and HeLaCIS-R, respectively) were used as in-vitro models. We studied the effects of PTX alone or in combination with CIS on cell viability, apoptosis, caspase-3, caspase-8, and caspase-9 activity, cleaved PARP-1, anti-apoptotic protein (Bcl-2 and Bcl-xL) levels, p65 phosphorylation, cadmium chloride (CdCl2) sensitivity, Platinum (Pt) accumulation, and glutathione (GSH) levels, as well as on the gene expression of GSH and drug transporters (influx and efflux). Results PTX sensitized SiHaCIS-R cells to the effects of CIS by inducing apoptosis, caspase activation, and PARP-1 cleavage. PTX treatment also decreased p65 phosphorylation, increased Pt levels, depleted GSH, and downregulated the expression of the ATP7A, ATP7B, GSR, and MGST1 genes. Conclusion PTX reverses the acquired phenotype of CIS resistance close to the sensitivity of parental SiHa cells.

Effect of Klotho protein during porcine oocyte maturation via Wnt signaling

Klotho protein is well-known as an anti-aging agent, however, several studies have suggested that Klotho protein also increases antioxidant activity and the reproductive system, as Klotho protein is closely associated with Wnt signaling. The objective of our study was to investigate the enhancement of porcine oocyte in vitro maturation via the Klotho protein-Wnt signaling pathway. Following immunohistochemistry and ELISA, we treated cells with Klotho protein during in vitro maturation. Lithium Chloride, a specific activator of Wnt signaling, was subsequently co-administered with Klotho protein. Mature oocytes subjected to treatments were used for the analysis of embryonic development, qRT-PCR, and immunocytochemistry. Treatment with 5pg/ml Klotho protein significantly increased cumulus cell expansion, blastocyst formation rates, and the total cell number of blastocysts. During cotreatment with 5mM Lithium Chloride and 5pg/ml Klotho protein, blastocyst formation rates were the highest in Klotho protein-treated oocytes and the lowest in Lithium Chloride-treated oocytes. Expression levels of Wnt signaling-related transcripts and proteins were significantly impacted by Klotho protein and Lithium Chloride. Moreover, cellular ATP levels and antioxidant activities were enhanced by Klotho protein treatment. These findings suggest a significant involvement of the Klotho proteinWnt signaling mechanism in porcine oocyte maturation.

Exogenous plant growth regulators/plant growth promoting bacteria roles in mitigating water-deficit stress on chicory (Cichorium pumilum Jacq.) at a physiological level

Plants respond differently to water-deficit stress conditions in the soil. In order to study different irrigation regimes and plant growth regulators/plant growth promoting bacteria effects on some physiological characteristics and inulin content in chicory plants, experiments were conducted as a factorial based on randomized complete block design with five replications at the greenhouse of Agricultural Faculty of Azarbaijan Shahid Madani University, Tabriz, Iran in 2017-2018. Experimental factors were different irrigation regimes: ((i) irrigation at the 55 %; (ii) irrigation at the 30 %; and (iii) irrigation at the 10 % of total available water capacity in the soil) and plant growth regulators including methyl jasmonate, uniconazole, chlormequat chloride and the solution containing plant growth promoting bacteria. Results indicated that the lowest relative water content, membrane stability index, chlorophyll a, b, total chlorophyll, carotenoids; soluble sugars and inulin in the roots; and the highest thiobarbituric acid reactive substances, proline, and soluble sugars in the leaves were related to severe water-deficit stress in the soil. Relative water content, membrane stability index, chlorophyll a, b, total chlorophyll, carotenoids, proline (except of plant growth promoting bacteria), soluble sugars and inulin increased, whereas thiobarbituric acid reactive substances decreased by the application of exogenous plant growth regulators/plant growth promoting bacteria compared with control plants. Interaction effects revealed that plant growth regulators/plant growth promoting bacteria could diminish water-deficit stress adverse effects in chicory plants at a physiological level by regulating endogenous phytohormones and antioxidant enzymes. In general, exogenous plant growth regulators especially uniconazole and plant growth promoting bacteria, improved inulin content in chicory plants compared with control plants.

In situ Fe3O4 nanoparticles coating of polymers for separating hazardous PVC from microplastic mixtures

Poly(vinyl chloride) (PVC) poses great challenges to the recycling of plastic wastes since it highly deteriorates the properties of other plastics and induces the formation of hazardous chlorinated dioxins and furans. For the first time, we developed a novel hydrophilization method of polymers, the in situ magnetite (Fe3O4) nanoparticles (NPs) coating, to facilitate the flotation separation of PVC from microplastic mixtures. A homogeneous Fe3O4 NPs layer was selectively fabricated on the surface of non-PVC microplastics via a facile in situ coprecipitation method. This obviously decreased the contact angle of non-PVC microplastics by approximately 30 degrees due to the plenty of hydroxyl groups on the surface of Fe3O4 NPs. However, the fabrication was not observed on the surface of PVC due to the weak interaction between Fe3+/Fe2+ and the surface of PVC. In this regard, the application of in situ Fe3O4 NPs coating in the flotation separation of PVC was systematically optimized using Box-Behnken design of response surface methodology. Quadratic models were generated to predict the floatability of microplastics, ascertain the effect of independent and interacted parameters, and numerically optimize the separation efficiency. Under optimum conditions, the Removal rate, Purity, and Recovery of PVC were 100.0%, 99.6%, and 100.0%, respectively. This study provides novel insights into the surface hydrophilization of polymers and shows promising prospects for facilitating the recycling of plastic wastes.
