Oligomerization and Polymerization of Isoprene Catalyzed by Alkylaluminium with Different Structures

Alkylaluminium (AlR3), as co-catalyst component in Ziegler-Natta catalytic system, plays important roles in the alkylation, forming and changing the structure and concentration of active centers through the reduction and reversible adsorption-desorption reactions with the metal compound of the catalyst, acting as chain transfer agent, etc. However, the alkylaluminium itself do have the catalytic effect on the conjugated diene monomers. In this article, alkylaluminium with different structures such as triethylaluminium (AlEt3), triisobutylaluminium (Al(i-Bu)(3)), diisobutylaluminium hydride (AlH(i-Bu)(2)), diethylaluminium chloride (AlEt2Cl), ethylaluminium dichloride (AlEtCl2) were used to catalyze isoprene oligomerization and polymerization. The effects of the structure and concentration of alkylaluminiums (n(Al)/n(M)=7 x 10(-5), 35 x 10(-5), 350 x 10(-5), 1050 x 10(-5)) on the catalytic behaviors of isoprene were studied. The microstructure (trans-1,4 and cis-1,4), molecular weight and molecular weight distribution of the products were characterized by H-1 nuclear magnetic resonance spectroscopy (H-1 NMR), gel permeation chromatography (GPC) and gas chromatography-mass spectrometry (GC-MS). It was found that alkylaluminium could initiate oligomerization and cationic polymerization of isoprene under the minor incorporation of H2O, which were affected greatly by the structure and concentration of alkylaluminium. Using AIEtCl(2) led to the highest catalytic activity and produced products containing more linear polymers with mixed cis-1,4/trans-1,4 structures when n(Al)/n(M)=1050 x 10(-5). The Al(i-Bu)(3) and AlH(i-Bu)(2) didn’t have basically cation initiation ability, which led to isoprene oligomerization. The alkylaluminium with n(Al)/n(M)<= 350 x10(-5) had negligible influence on the isoprene polymerization and oligomerization. And lower or higher alkylaluminium concentration were not beneficial to obtain polyisoprene with high molecular weight. The catalytic mechanism of alkylaluminium on isoprene was discussed, which provided a further understanding on the catalytic behavior of alkylaluminium components in Ziegler-Natta catalyst and the effect of alkylaluminium on polymers.

Ecofriendly renewable hydrogels based on whey protein and for slow release of fertilizers and soil conditioning

Hydrogels show potential in agriculture for overcoming issues associated with conventional fertilizers and irrigation. A combination of hydrogels and fertilizers would limit the loss of fertilizer and curb environmental impact, especially for nitrogen-based compounds, in addition to diminishing the frequency of irrigation. A set of renewable hydrogels, based on a mixture of whey proteins and alginic acid were developed as a soil conditioner and for sustained release of the urea fertilizer. Four separate formulations were prepared from different proteins at a polysaccharide ratio of 1%-10% w/w (with respect to protein content). The hydrogels were prepared by a heat-set process, applying calcium chloride as the cross-linking agent. The fertilizer was loaded into the hydrogel during the preparation stage to heighten loading efficiency. Investigation was made into the impact of alginic acid content on morphology, swelling behaviour encompassing repeated swelling-drying cycles, and water retention in soil under different pH conditions. The loading capacity and release of urea from the hydrogels were studied, and the data processed in accordance with a mathematical model to discern any correlation between the structure of the hydrogel, the presence of alginic acid and the release mechanism. The results demonstrate how adding alginic acid promotes possible utilization of the whey protein hydrogel in agriculture. (c) 2020 Elsevier Ltd. All rights reserved.

Tiao Geng decoction inhibits tributyltin chloride-induced GT1-7 neuronal apoptosis through ASK1/MKK7/JNK signaling pathway

Ethnopharmacological relevance: Tiao Geng (TG) decoction is a Chinese herbal medicine extract that has been utilized for the treatment of menopausal symptoms for a history of over 30 years. In our previous study, we suggest that TG decoction possibly exerts an anti-apoptotic effect on hypothalamic neurons of ovariectomized rats via the ASK1/MKK7/JNK pathway. Tributyltin chloride (TBTC) causes oxidative damage and induces apoptosis of primary hypothalamic neurons in rats. Aim of the study: The present work aimed to explore the inhibition of TG decoction on TBTC-induced GT1-7 cell apoptosis and its possible molecular mechanism. Materials and methods: The GT1-7 cell line was exposed to TG decoction at diverse doses (31.25, 62.5, 125 mu g/mL) for 24 h and later with TBTC (1 mg/L) for 1 h, with 17 beta-E-2 (100 nM) treatment being the positive control. Then, CCK8 assay was conducted to evaluate cell viability, while flow cytometric analysis was conducted to examine the apoptosis level. Related pathways and differentially expressed proteins were identified by tandem mass tag (TMT)-based quantitative phosphoproteomics. qRT-PCR was carried out to examine mRNA levels of Bax and B-cell lymphoma-2 (Bcl-2). Western blotting was performed to detect the levels of Bax, Bcl-2, c-Jun, c-Jun N terminal kinase (JNK), Caspase-3 (Casp3), Mitogen-activated protein kinase kinase 7 (MKK7), and apoptosis signal-regulating kinase 1 (ASK1) . Finally, cells were pretreated with SP600125, an inhibitor of JNK, later the expression of JNK and Casp3 was measured. Results: Application of TG decoction mitigated the GT1-7 cell apoptosis and injury caused by TBTC; besides, it inhibited the activation of the ASK1/MKK7/JNK pathway. Moreover, Bcl-2/Bax ratio became higher, and the MKK7, ASK1, Casp3 and c-Jun levels were inhibited. Besides, TG decoction combined with SP600125 (the JNK inhibitor) more significantly inhibited GT1-7 cell apoptosis caused by TBTC. Conclusion: As discovered from the experiment in this study, TG decoction has a neuroprotective effect, which is achieved through inhibiting the ASK1/MKK7/JNK signal transduction pathway to reduce GT1-7 cell apoptosis.

Degradation of hydroxychloroquine by electrochemical advanced oxidation processes

In this work, the degradation of hydroxychloroquine (HCQ) drug in aqueous solution by electrochemical advanced oxidation processes including electrochemical oxidation (EO) using boron doped diamond (BDD) and its combination with UV irradiation (photo-assisted electrochemical oxidation, PEO) and sonication (sono-assisted electrochemical oxidation, SEO) was investigated. EO using BDD anode achieved the complete depletion of HCQ from aqueous solutions in regardless of HCQ concentration, current density, and initial pH value. The decay of HCQ was more rapid than total organic carbon (TOC) indicating that the degradation of HCQ by EO using BDD anode involves successive steps leading to the formation of organic intermediates that end to mineralize. Furthermore, the results demonstrated the release chloride (Cl-) ions at the first stages of HCQ degradation. In addition, the organic nitrogen was converted mainly into NO3- and NH4+ and small amounts of volatile nitrogen species (NH3 and NOx). Chromatography analysis confirmed the formation of 7-chloro-4-quinolinamine (CQLA), oxamic and oxalic acids as intermediates of HCQ degradation by EO using BDD anode. The combination of EO with UV irradiation or sonication enhances the kinetics and the efficacy of HCQ oxidation. PEO requires the lowest energy consumption (EC) of 63 kWh/m(3) showing its cost-effectiveness. PEO has the potential to be an excellent alternative method for the treatment of wastewaters contaminated with HCQ drug and its derivatives.

Effects of Saline Water Irrigation and Biochar Amendment on Okra Growth and Nutrient Leaching in Coastal Saline Soils

Excess soluble salts in the soil and irrigation water creates difficulties for plant growth and lowers nutrient availability in the soil. Organic ameliorants such as biochar are believed to be one of the effective treatments for soil improvement and salt stress alleviating. To access the response of different types of salt in irrigation water and bamboo biochar amendment on okra growth and nutrient leaching in coastal saline soils, both column and pot experiments were carried out from 2018 to 2019 in Nanjing, China. The experimental results suggested that okra growth and yield were reduced notably under the saline condition in contrast with the control treatment. Anthocyanin accumulation, which is a sign of growth stress, was decreased after the application of different types of salt. Furthermore, the application of different types of salt effectively increases malondialdehyde (MDA) content in sodium sulfate (Na2SO4) and sodium chloride (NaCl) treatments at both 2.0 and 4.0 dS/m. Meanwhile, MDA was reduced in CaCl2 and MgCl2 treatments at both 2.0 and 4.0 dS/m. Nevertheless, bamboo biochar remarkably ameliorated okra seed germination, growth process, and yield due to salt stress. Besides, the leaching of nitrate, total nitrogen and total phosphorus is significantly reduced in the case of biochar application. In conclusion, our study suggested that bamboo biochar is one of the alternatives of ameliorant to improve the productivity of plants in coastal saline soils.

Hyperchloremia in critically ill patients: association with outcomes and prediction using electronic health record data

Background Increased chloride in the context of intravenous fluid chloride load and serum chloride levels (hyperchloremia) have previously been associated with increased morbidity and mortality in select subpopulations of intensive care unit (ICU) patients (e.g patients with sepsis). Here, we study the general ICU population of the Medical Information Mart for Intensive Care III (MIMIC-III) database to corroborate these associations, and propose a supervised learning model for the prediction of hyperchloremia in ICU patients. Methods We assessed hyperchloremia and chloride load and their associations with several outcomes (ICU mortality, new acute kidney injury [AKI] by day 7, and multiple organ dysfunction syndrome [MODS] on day 7) using regression analysis. Four predictive supervised learning classifiers were trained to predict hyperchloremia using features representative of clinical records from the first 24h of adult ICU stays. Results Hyperchloremia was shown to have an independent association with increased odds of ICU mortality, new AKI by day 7, and MODS on day 7. High chloride load was also associated with increased odds of ICU mortality. Our best performing supervised learning model predicted second-day hyperchloremia with an AUC of 0.76 and a number needed to alert (NNA) of 7-a clinically-actionable rate. Conclusions Our results support the use of predictive models to aid clinicians in monitoring for and preventing hyperchloremia in high-risk patients and offers an opportunity to improve patient outcomes.

Synthesis and Coordination Behavior of a New Hybrid Bidentate Ligand with Phosphine and Silylene Donors

This work describes the synthesis and coordination behavior of a new mixed-donor ligand PhC(NtBu)(2)SiC6H4PPh2 (1) containing both silylene and phosphine donor sites. Ligand 1 was synthesized from a reaction of ortho-lithiated diphenylphosphinobenzene (LiC6H4PPh2) with chlorosilylene (PhC(NtBu)(2)SiCl). Treatment of 1 with Se and GeCl2 resulted in Si-IV compounds 2 and 3 by selective oxidation of the silylene donor. This strong sigma-donor ligand induces dissociation of CuCl and PhBCl2 leading to formation of ionic complexes 4 and 5 respectively. The reaction of 1 with ZnCl2 and AlCl3 resulted in the formation of chelate complexes 5 and 7, respectively, while treatment with EtAlCl2 and GaCl3 forms monodentate complexes 8 and 9. X-ray analysis of 4 showed that the copper is in the spiro center of the two five-membered rings. Moreover, the copper(I)chloride has not been oxidized but dissociates to Cu+ and [CuCl2](-). All the compounds are well characterized by mass spectrometry, elemental analysis, NMR spectroscopy, and single-crystal X-ray diffraction studies.
