Stomatal movements are enabled by changes in guard cell turgor facilitated via transient accumulation of inorganic and organic ions imported from the apoplast or biosynthesized within guard cells. Under salinity, excess salt ions accumulate within plant tissues resulting in osmotic and ionic stress. To elucidate whether (a) Na+ and Cl- concentrations increase in guard cells in response to long-term NaCl exposure and how (b) guard cell metabolism acclimates to the anticipated stress, we profiled the ions and primary metabolites of leaves, the apoplast and isolated guard cells at darkness and during light, that is, closed and fully opened stomata. In contrast to leaves, the primary metabolism of guard cell preparations remained predominantly unaffected by increased salt ion concentrations. Orchestrated reductions of stomatal aperture and guard cell osmolyte synthesis were found, but unlike in leaves, no increases of stress responsive metabolites or compatible solutes occurred. Diverging regulation of guard cell metabolism might be a prerequisite to facilitate the constant adjustment of turgor that affects aperture. Moreover, the photoperiod-dependent sucrose accumulation in the apoplast and guard cells changed to a permanently replete condition under NaCl, indicating that stress-related photosynthate accumulation in leaves contributes to the permanent closing response of stomata under stress.

Cadmium (Cd) is a toxic metal, which seems to be crucial during the prepubertal period. Cd can destroy the structural integrity of the blood-brain barrier (BBB) and enters into the brain. Although the brain is susceptible to neurotoxicity induced by Cd, the effects of Cd on the brain, particularly hypothalamic transcriptome, are still relatively poorly understood. Therefore, we investigated the molecular effects of Cd exposure on the hypothalamus by profiling the transcriptomic response of the hypothalamus to high dose of Cd (25 mg/kg bw/day cadmium chloride (CdCl2)) during the prepubertal period in Sprague-Dawley female rats. After sequencing and annotation, differential expression analysis revealed 1656 genes that were differentially expressed that 108 of them were classified into 37 transcription factor (TF) families. According to gene ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, these differentially expressed genes (DEGs) were involved in different biological processes and neurological disorders including Alzheimer’s disease (AD), Huntington’s disease (HD), and Parkinson’s disease (PD), prolactin signaling pathway, PI3K/Akt signaling, and dopaminergic synapse. Five transcripts were selected for further analyses with Real-time quantitative PCR (RT-qPCR). The RT-qPCR results were mostly consistent with those from the high throughput RNA sequencing (RNA-seq). Cresyl violet staining clearly showed an increased neuronal degeneration in the dorsomedial hypothalamus (DMH) and arcuate (Arc) nuclei of the CdCl2 group. Overall, this study demonstrates that prepubertal exposure to high doses of Cd induces hypothalamic injury through transcriptome profiling alteration in female rats, which reveals the new mechanisms of pathogenesis of Cd in the hypothalamus.

Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, Quality Control of 1,2-Bis(2-chloroethoxy)ethane, 112-26-5, Name is 1,2-Bis(2-chloroethoxy)ethane, SMILES is ClCCOCCOCCCl, belongs to chlorides-buliding-blocks compound.

Large disparities on micro- and macroplastic concentrations are to be expected between residential, industrial, natural and agricultural areas, since specific uses of plastic will determine the magnitude of the corresponding emissions. The aim of this work was to develop a method to regionalize emissions of macroplastic and microplastic for soil, freshwater and air using geographical datasets on land-use statistics, traffic and population densities, wastewater treatment plants and combined sewer overflows as proxies. High resolution maps of the emissions were then generated for micro- and macroplastic using emission data available for Switzerland for seven commonly used polymers (low-density-polyethylene, high-density-polyethylene (HDPE), polypropylene (PP), polystyrene, expanded polystyrene, polyvinyl-chloride and polyethylene-terephthalate). Most of the emissions can be found in areas with high human activity, but the influence of the different proxies varies for each polymer. The median emission rate of macroplastic on soil varies from 0.0006 to 0.06 kg/ha/year, whereas no emission flows are predicted for more than 50% of the raster cells for microplastic regardless of the polymer, but the maxima can reach up to 12.7 kg/ha/a in the case of HDPE. The average emission rate of macroplastic along river segments ranges between 0.062 kg/km/a and 1.5 kg/km/a. For microplastic, the average emission rate varies from 0.0025 kg/km/a to 0.11 kg/km/a. The analysis reveals that a significant deviation is expected if the population density is used as only proxy. The correlation between the population density and the predicted emissions is only r = 0.16-023 fora cell size of 100 x 100 m and goes up to r = 0.86-0.88 fora resolution of 10 km, however an r of only 056-0.68 is observed for those polymers used a lot in agriculture such as HDPE and PP. The emission maps obtained in this work can serve as input to regionalized fate models for macro- and microplastics. (C) 2020 The Authors. Published by Elsevier B.V.

Forward osmosis (FO) is an emerging low energy membrane-based technology and can be applied if the diluted draw solution (DS) is directly utilized without additional recovery/treatment. In this study, FO process was applied for the treatment of textile industry wastewater using fertilizer as DS. This paper focuses on modelling and optimisation of FO process using machine learning techniques like Response Surface Methodology (RSM), Artificial Neural Network (ANN) and Adaptive Neuro-Fuzzy Inference System (ANFIS). To model the FO process, central composite design was utilized to examine the effect of initial draw concentration, initial feed concentration, time, initial feed pH and temperature on the water flux and reverse salt flux. The optimum water flux (8.527 Lm(-2).h(-1) (LMH)) and reverse salt flux (7.246 g.m(-2).h(-1) (GMH)) was obtained using initial draw concentration of 1.625 M, initial feed concentration of 1090 mg/L, reaction time of 90 min, initial feed pH of 7.33 and temperature of 35 degrees C. Under these conditions, FO performance was carried out experimentally and validated with the models. The model developed for the FO process by ANN and RSM was considerably better than that of other models in terms of precision of predicting the water flux and the reverse salt flux, respectively. About six different chemical fertilizer solutions were screened and tested at optimum conditions to identify the best suitable fertilizer DS for FO process using textile wastewater. The results indicate that Diammonium Phosphate (DAP) along with Potassium Chloride (KCl) fertilizer as DS gave better performance with respect to water flux. (C) 2020 Elsevier Ltd.

Background: The availability of generic versions of bortezomib raises questions about the reliability of extrapolating stability data from one brand to another. Objective: To evaluate the stability of bortezomib formulations available from Janssen, Teva Canada, Actavis Pharma, Dr. Reddy’s Laboratories, Apotex, and MDA, reconstituted with 0.9% sodium chloride (normal saline) to produce solutions of either 1.0 or 2.5 mg/mL and stored over at least 21 days under refrigeration (4 degrees C) or at room temperature (either 23 degrees C or 25 degrees C) in the manufacturer’s original glass vials or in polypropylene syringes. Methods: On study day 0, solutions with concentration 1.0 mg/mL or 2.5 mg/mL of the Teva, Actavis, Dr. Reddy’s, Apotex, and MDA generic formulations were prepared. Three units of each type of container (glass vials and syringes) were stored at 4 degrees C and 3 units at room temperature. Concentration and physical inspection were completed on at least 8 study days (including day 0) over a 21- to 84-day study period. Bortezomib concentrations were determined by a validated stability-indicating liquid chromatographic method with ultraviolet detection. The end point of these studies was the time to reach 90% of the initial concentration (T-90) with 95% confidence, which is expressed as T-9095%CI, where CI refers to the confidence interval. In addition to estimating the T-9095%CI, differences in stability among products from all manufacturers were compared using multiple linear regression. Previously published data for the Janssen product were included in the overall comparisons. Results: In all of the studies, the analytical method separated degradation products from bortezomib, such that the concentration of bortezomib was measured specifically, accurately (deviations < 2.5%), and reproducibly (average replicate error 2.5%). During all studies, solutions retained more than 94% of the initial concentration at 4 degrees C. The T-9095% CI exceeded the study period for all formulations under all combinations of concentration, container, and temperature, except the 84-day study for the MDA product. Multiple linear regression showed no significant differences among manufacturers (p = 0.57). Conclusions: In this study, formulations of bortezomib currently marketed in Canada (by Janssen, Teva Canada, Actavis Pharma, Dr. Reddy's Laboratories, Apotex, and MDA) were pharmaceutically equivalent and interchangeable. Given that there was no difference in stability related to manufacturer, nominal concentration, or container, we conclude that these formulations are physically and chemically stable for at least 35 days under refrigeration and at least 25 days at room temperature.

Ionic liquid-based microwave-assisted extraction (MAE-IL) has been applied for the separation of essential oils (EOs) from Citrus sinensis var. Valencia peels. Two imidazolium ionic liquids, 1-ethyl-3-methyl imidazolium acetate ([C(2)mim]OAc) and 1-butyl-3-methyl imidazolium chloride ([C-4 mim]Cl), were investigated for extraction efficiency, thermal behavior of the process, and chemical composition of the EOs obtained. During extractions, two different concentrations of ionic liquids (ILs) were studied (5% or 10 %), and the proposed MAE-IL was evaluated in comparison with usual microwave-assisted extraction (MAE) using water as solvent. Results indicated that both concentrations of ILs influenced EO extraction, thermal behavior, and chemical composition. However, [C(2)mim]OAc was more efficient, increasing extraction velocity by 10 times, enhancing extraction efficiency of EOs (39 %), and increasing the presence of oxyterpene compounds in the EOs. However, the great ability of ILs to interact with microwaves had an impact on the thermal history of the sample, reaching almost 110 degrees C, promoting the presence of compounds related to thermal effect.

Assembly of the top-down graphene units mostly results in 3D porous structure with randomly organized pores. The direct bottom-up synthesis of macroscopic 2D graphene sheets with organized pores are long sought in materials chemistry field, but rarely achieved. Herein, we present a self-catalysis-assisted bottom-up route using L-glutamic acid and iron chloride as starting materials for the fabrication of the millimeter-sized few-layer graphene sheets with aligned porous channels parallel to the 2D direction. The amino- and carboxyl-functional groups in L-glutamic acid can coordinate with iron cations, thus allowing an atomic dispersion of iron cations. The pyrolysis thus initiated the growth of graphene catalyzed by in situ generated iron nanoparticles, and a dynamic flow of iron nanoparticles eventually led to the formation of millimeter-sized few-layer graphene sheets with aligned channels (60-85 nm in diameter). Used as anodes in lithium-ion batteries, these graphene sheets showed a good rate capability (142 mA h g(-1) at 2 A g(-1)) and high capacity retention of 93% at 2 A g(-1) after 1200 cycles. Kinetic analysis revealed that lithium ions storage was dominated by diffusion behavior and capacitive behavior together, in that graphene sheets with aligned channels could accelerate electron transfer and shorten lithium ions transport pathway. This work provides a novel approach to prepare unique porous graphene materials with specific structure for energy storage.

Despite the successful detection performance of electronic nose in laboratories, they face challenges for use in the industry due to their accuracy reduction resulted from variable ambient properties especially relative humidity (RH) variation which is studied here. Responses of a single temperature modulated metal oxide gas sensor have been analyzed by SVM and k-NN methods to achieve a detector for low concentration levels of acetone, ethanol, 1-propanol and 1-butanol in air. The classifier models were designed and tested under different train-test conditions which showed that studied gases can be detected by the classifier if only they were measured in the same train and test environmental conditions and deviation of humidity level from train condition, reduces the detection accuracy to less than 60%. The accuracy increases by expanding the training dataset and training the system with responses carried out for gas with various RH contents. It was also shown that by using CaCl2 at the rout of gas flow, the destructive effect of RH variation is reduced and the detection accuracy increases to above 90%, while to achieve this accuracy, it is not necessary to train the system in all humidity conditions. By this method, the number of required test for system training reduces drastically. The method can be generalized to other electronic nose and gas detectors which suffer from humidity variations.

Purpose of review This review focuses on recent efforts in identifying with-no-lysine kinase 4 (WNK4) as a physiological intracellular chloride sensor and exploring regulators of intracellular chloride concentration ([Cl-]i) in the distal convoluted tubule (DCT). Recent findings The discovery of WNK1’s chloride-binding site provides the mechanistic details of the chloride-sensing regulation of WNK kinases. The subsequent in-vitro studies reveal that the chloride sensitivities of WNK kinases were variable. Because of its highest chloride sensitivity and dominant expression, WNK4 emerges as the leading candidate of the chloride sensor in DCT. The presentation of hypertension and increased sodium-chloride cotransporter (NCC) activity in chloride-insensitive WNK4 mice proved that WNK4 is inhibitable by physiological [Cl-]i in DCT. The chloride-mediated WNK4 regulation is responsible for hypokalemia-induced NCC activation but unnecessary for hyperkalemia-induced NCC deactivation. This chloride-sensing mechanism requires basolateral potassium and chloride channels or cotransporters, including Kir4.1/5.1, ClC-Kb, and possibly KCCs, to modulate [Cl-]i in response to the changes of plasma potassium. WNK4 is both a master NCC stimulator and an in-vivo chloride sensor in DCT. The understanding of chloride-mediated regulation of WNK4 explains the inverse relationship between dietary potassium intake and NCC activity.

The present study reports the use of the O-3/H2O2 process in the pretreatment of the mother liquor of gas field wastewater (ML-GFW), obtained from the multi-effect distillation treatment of the gas field wastewater. The range of optimal operation conditions was obtained by single-factor experiments. Response surface methodology (RSM) based on the central composite design (CCD) was used for the optimization procedure. A regression model with Total organic carbon (TOC) removal efficiency as the response value was established (R-2 = 0.9865). The three key factors were arranged according to their significance as: pH>H2O2 dosage>ozone flow rate. The model predicted that the best operation conditions could be obtained at a pH of 10.9, an ozone flow rate of 0.8 L/min, and H2O2 dosage of 6.2 mL. The dosing ratio of ozone was calculated to be 9.84 mg O-3/mg TOC. The maximum removal efficiency predicted was 75.9%, while the measured value was 72.3%. The relative deviation was found to be in an acceptable range. The ozone utilization and free radical quenching experiments showed that the addition of H2O2 promoted the decomposition of ozone to produce hydroxyl radicals (center dot OH). This also improved the ozone utilization efficiency. Gas chromatography-mass spectrometry (GC-MS) analysis showed that most of the organic matters in ML-GFW were degraded, while some residuals needed further treatment. This study provided the data and the necessary technical supports for further research on the treatment of ML-GFW.
