Long-term spatiotemporal variations of atmospheric sulfur, nitrogen and particle pollutants in Chongqing, southwest China: implication of industrial transfer

Abstract

Industrial transfer has swept through in China. However, there is still a knowledge gap about its environmental effects. In this study, industrial transfer status was assessed and evaluated by industrial ratios (%; the gross product contributions of the secondary industry to the whole industry) and the impact of such transfer on atmospheric environment (SO2, NO2, PM10 (particles with aerodynamic diameter less than 10 μm), precipitations of SO42−, NO3, and NH4+) in the 38 districts and counties in Chongqing was analyzed and discussed for the period of 2006–2015. Results showed that industries were transferred obviously from the main urban region (MUR) into the 1-h economic region (OHER). Atmospheric sulfur and PM10 were efficiently put in control, but atmospheric nitrogen (NO2; precipitations of NO3 and NH4+) was increasing and posted a potential threat to air quality especially during 2011–2015. Correlations showed that industrial ratios had significantly positive relationships with concentrations of ambient SO2 and PM10 in the MUR and ambient NO2 in the OHER (p < 0.05) while a remarkably negative one with concentrations of ambient SO2 in the OHER (p < 0.05) during 2006–2015, implying that industrial transfer could be effective in transferring sulfur pollution but not as efficient in transferring atmospheric nitrogen and PM10 pollutions as SO2 between in the MUR and OHER. More measures should be taken to reduce nitrogen and PM10 emission and a regional monitoring network of ambient NH3 is in urgent need.

Development of biodegradable coatings for maize seeds and their application for Azospirillum brasilense immobilization

Abstract

The objective of this study was to develop biodegradable coatings for agriculture crop seeds based on starch, gelatin, and polyvinyl alcohol (PVA). Developed materials were characterized according to their microstructures, barrier properties, influence on germination of maize seeds, and ability to sustain Azospirillum brasilense Ab-V5 viability in coated maize seeds. The coatings were obtained employing different proportions of starch, gelatin, and PVA, ranging from 0 to 3.0 g/100 g of each material, respectively. Samples formulated with the pure polymers showed the highest values of water absorption capacity, solubility, and water vapor permeability, and the ternary mixtures showed the lowest values. Single polymer formulations and the binary starch-gelatin mixture (CS50GL50) favored maize seeds germination compared to the uncoated maize seeds. In addition, seed coating obtained from CS50GL50 formulation resulted in A. brasilense Ab-V5 viability in coated seeds up to 15 days after bacterial immobilization, being considered a promising low-cost, biodegradable, and renewable source material to be used in agriculture.

Comparative analysis of two non-specific nucleases of the phospholipase D family from the plant pathogen competitor bacterium Pantoea agglomerans

Abstract

Bacterial non-specific nucleases of the phospholipase D family are widely distributed among the members of the Enterobacteriaceae. Each genome mainly contains a single copy of a gene encoding a phospholipase D family protein. However, two distantly related isozymes (< 40% identity at the protein level) were identified by BLAST-analyses in the plant pathogenic competitor enterobacterium Pantoea agglomerans. The two nucleases PaNuc-1 and PaNuc-2 were produced in Escherichia coli. Identical gene constructs and expression conditions resulted in the production of PaNuc-1 in soluble form, while PaNuc-2 remained insoluble in inclusion bodies. PaNuc-2 was refolded and both proteins were purified by a combination of affinity and ion exchange chromatography. Proteolytic removal of the HIS-tag allowed the characterization of pure and mature tag-less proteins. Enzymatic properties of both isozymes revealed that they are non-specific nucleases, displaying activities against RNA, single- and double-stranded genomic DNA as well as circular plasmids. However, their biochemical activity profiles were clearly different, with PaNuc-1 being optimally active at 70 °C and pH 7.0, while PaNuc-2 was most active at 45 °C and pH 7.0. The enzymes retained > 90% nuclease activity at EDTA concentrations of 4 mM (PaNuc-2) and 20 mM (PaNuc-1), respectively. Different enzymatic properties suggest that the roles of PaNuc-1 and PaNuc-2 differ in the cell and might be the result of functional diversification after an ancient gene duplication event took place. The fact that both enzymes could be easily produced in recombinant form and their tolerance against metal ion chelators in combination with a broad substrate promiscuity might pave the way to versatile biotechnological applications.

Bovine colostrum-driven modulation of intestinal epithelial cells for increased commensal colonisation

Abstract

Nutritional intake may influence the intestinal epithelial glycome and in turn the available attachment sites for bacteria. In this study, we tested the hypothesis that bovine colostrum may influence the intestinal cell surface and in turn the attachment of commensal organisms. Human HT-29 intestinal cells were exposed to a bovine colostrum fraction (BCF) rich in free oligosaccharides. The adherence of several commensal bacteria, comprising mainly bifidobacteria, to the intestinal cells was significantly enhanced (up to 52-fold) for all strains tested which spanned species that are found across the human lifespan. Importantly, the changes to the HT-29 cell surface did not support enhanced adhesion of the enteric pathogens tested. The gene expression profile of the HT-29 cells following treatment with the BCF was evaluated by microarray analysis. Many so called "glyco-genes" (glycosyltransferases and genes involved in the complex biosynthetic pathways of glycans) were found to be differentially regulated suggesting modulation of the enzymatic addition of sugars to glycoconjugate proteins. The microarray data was further validated by means of real-time PCR. The current findings provide an insight into how commensal microorganisms colonise the human gut and highlight the potential of colostrum and milk components as functional ingredients that can potentially increase commensal numbers in individuals with lower counts of health-promoting bacteria.

Immobilization of cellulase in the non-natural ionic liquid environments to enhance cellulase activity and functional stability

Abstract

Ionic liquids (ILs) have been applied as an environmentally friendly solvent in the pretreatment of lignocellulosic biomass for more than a decade. The ILs involved pretreatment processes for cellulases mediated saccharification lead to both the breakdown of cellulose crystallinity and the decrease of lignin content, thereby improving the solubility of cellulose and the accessibility of cellulase. However, most cellulases are partially or completely inactivated in the presence of even low amount of ILs. Immobilized cellulases are found to perform improved stability and higher apparent activity in practical application compared with its free counterparts. Enzyme immobilization therefore has become a promising way to relieve the deactivation of cellulase in ILs. Various immobilization carriers and methods have been developed and achieved satisfactory results in improving the stability, activity, and recycling of cellulases in IL pretreatment systems. This review aims to provide detailed introduction of immobilization methods and carrier materials of cellulase, including natural polysaccharides, synthetic polymers, inorganic materials, magnetic materials, and newly developed composite materials, and illustrate key methodologies in improving the performance of cellulase in the presence of ILs. Especially, novel materials and concepts from the recently representative researches are focused and discussed comprehensively, and future trends in immobilization of cellulases in non-natural ILs environments are speculated in the end.

Agronomic and environmental factors affecting cultivation of the winter mushroom or Enokitake: achievements and prospects

Abstract

The global interest in production of the winter mushroom or Enokitake (Flammulina filiformis previously known as Flammulina velutipes) is increasing owing to its nutritional and medicinally important bioactive compounds along with a marketable texture and flavor. This review presents the state of knowledge on achievements in solid-state cultivation and submerged cultures of Enokitake and how they are influenced by environmental factors and agronomic characteristics. A wide range of basic lignocellulosic substrates and supplementations have been reviewed in order to formulate an efficient and locally available substrate. Domestication of wild types of Enokitake and its economic and research implications are also discussed. Besides, the influence of environmental and agronomic factors on production and efficacy of the most important biologically active metabolites of Enokitake in both solid-state cultivation and submerged cultures has been discussed. Some of shortcomings of studies reporting cultivation of Enokitake are described and their contribution to future prospects is also discussed in this review.

Neuroblastoma RAS Viral Oncogene Homolog (NRAS) Is a Novel Prognostic Marker and Contributes to Sorafenib Resistance in Hepatocellular Carcinoma

Publication date: March 2019

Source: Neoplasia, Volume 21, Issue 3

Author(s): Peter Dietrich, Anne Gaza, Laura Wormser, Valerie Fritz, Claus Hellerbrand, Anja Katrin Bosserhoff

Abstract

Inhibition of the RAS-RAF-ERK-pathway using sorafenib as a first-line and regorafenib as a second-line treatment approach is the only effective therapeutic strategy for advanced hepatocellular carcinoma (HCC). Recent studies suggest that wild-type KRAS and HRAS isoforms could majorly contribute to HCC progression and sorafenib resistance. In contrast, the role of neuroblastoma RAS viral oncogene homolog (NRAS) in HCC remained elusive. In this study, wild-type NRAS was found to be overexpressed in HCC cell lines, preclinical HCC models, and human HCC tissues. Moreover, NRAS overexpression correlated with poor survival and proliferation in vivo. However, si-RNA-pool–mediated NRAS knockdown showed only slight effects on HCC proliferation, clonogenicity, and AKT activity. We determined that KRAS upregulation served as a functional compensatory mechanism in the absence of NRAS, which was overcome by combined inhibition of NRAS and KRAS in HCC cells. Furthermore, NRAS expression was elevated in sorafenib-resistant compared to nonresistant HCC cells, and NRAS knockdown enhanced sorafenib efficacy in resistant cells. In summary, NRAS appears to be a prognostic marker in HCC and contributes to sorafenib resistance. Regarding potential therapeutic strategies, NRAS inhibition in HCC should be combined with KRAS inhibition to prevent KRAS-mediated rescue effects.

A new immunoassay of hybrid nanomater conjugated to aptamers for the detection of dengue virus

Publication date: 15 May 2019

Source: Talanta, Volume 197

Author(s): Caroline R. Basso, Bruno P. Crulhas, Massimiliano Magro, Fabio Vianello, Valber A. Pedrosa

Abstract

A new immunosensor using hybrid nanomaterials for the detection of dengue virus was demonstrated in this work. This immunosensor composed of nanoparticles of γ-Fe2O3(SAMN) modified with MPA- SAMN@MPA was characterized by FTIR spectroscopy, transmission electron microscopy,quartz crystal microbalance, UV–vis and LSPR technique. The binding of SAMN@MPA with AuNPs conjugated with aptamers(SAMN@MPA@AuNPs@aptamer) provides specific chemical bonds to four dengue serotypes. Colorimetric changes in the modification steps provided rapid visual detection of the virus without the use of equipment. Variations of aptamers concentrations 1.0-10.0 μM where the 3.0 μM aptamer concentration is sufficient to completely cover the surface of the modified AuNPs with an R2 value of> 0.99. This new proposed methodology presenting some advantages in relation to traditional detection methods such as time optimization and cost,can be used as a diagnostic method.

Environmentally friendly etching of stainless steel wire for plunger-in-needle liquid-phase microextraction of polycyclic aromatic hydrocarbons

Publication date: 15 May 2019

Source: Talanta, Volume 197

Author(s): Piyaluk Nurerk, Christina Shu Min Liew, Opas Bunkoed, Proespichaya Kanatharana, Hian Kee Lee

Abstract

An environmentally friendly method of etching a stainless steel plunger wire, to replace the conventional hydrofluoric acid approach, was developed for plunger-in-needle liquid phase-microextraction (PIN-LPME). The one-step etching procedure was performed by immersing the plunger wire in a ferric chloride-hydrochloric acid (FeCl3-HCl) solution. The etched wire was then used for LPME as the organic solvent holder. After solvent coating, the wire was directly exposed to a water sample for extraction of polycyclic aromatic hydrocarbons (PAHs), which were then subjected to thermal desorption in the injector of a gas chromatograph for gas chromatography-mass spectrometric (GC-MS) analysis. The parameters affecting PIN-LPME efficiencies (i.e., extraction solvent, solvent coating mode and time, stirring rate, extraction time and salting effect) were also investigated. Under the most favourable conditions, PIN-LPME-GC-MS exhibited high enrichment factors of between 70 and 349 for the 9 PAHs, low detection limits (between 0.006 and 0.058 ng mL−1), and good precision (with relative standard deviations ranging from 4.4% to 9.7%). The developed method was successfully applied for the extraction and determination of PAHs in tap, river and drain water samples. Good relative recoveries of the PAHs over the range of 84.3–101.9% were obtained with spiked genuine water samples.

A combined targeted/untargeted LC-MS/MS-based screening approach for mammalian cell lines treated with ionic liquids: Toxicity correlates with metabolic profile

Publication date: 15 May 2019

Source: Talanta, Volume 197

Author(s): Corinna Sanwald, Alexandra Robciuc, Suvi-Katriina Ruokonen, Susanne K. Wiedmer, Michael Lämmerhofer

Abstract

This work presents the development and validation of a quantitative HILIC UHPLC-ESI-QTOF-MS/MS method for amino acids combined with untargeted metabolic profiling of human corneal epithelial (HCE) cells after treatment with ionic liquids. The work included a preliminary metabotoxicity screening of 14 different ionic liquids, of which 9 carefully selected ionic liquids were chosen for a metabolomics study. This study is focused on the correlation between the toxicity of the ionic liquids and their metabolic profiles. The method development included the comparison of different MS/MS acquisition modes. A sequential window acquisition of all theoretical fragment ion mass spectra (SWATH) method with variable Q1 window widths and narrow Q1 target windows of 5 Da for most of the amino acids was selected as the optimal acquisition mode. Due to the absence of a true blank matrix, 13C,15N-isotopically labelled amino acids were utilized as surrogate calibrants, instead of proteinogenic amino acids. Partial least squares (PLS) analysis of the median effective concentrations (EC50) of 9 selected ionic liquids showed a correlation with their metabolic profile measured by the untargeted screening.

Intracerebral injection of R-(-)-Apomorphine into the nucleus accumbens decreased carbachol-induced 22-kHz ultrasonic vocalizations in rats

Publication date: Available online 26 January 2019

Source: Behavioural Brain Research

Author(s): Michael Silkstone, Stefan M. Brudzynski

Abstract

Rats can produce ultrasonic vocalizations (USVs) in a variety of different contexts that signal their emotional state to conspecifics. Under distress, rats can emit 22-kHz USVs, while during positive pro-social interactions rats can emit frequency-modulated (FM) 50-kHz USVs. It has been previously reported that rats with increasing emission of FM 50-kHz USVs in anticipation of rewarding electrical stimulation or positive pro-social interaction decrease the number of emitted 22-kHz USVs. The purpose of the present investigation was to determine, in a pharmacological-behavioural experiment, if the positive emotional arousal of the rat indexed by the number of emitted FM 50-kHz USVs can decrease the magnitude of a subsequent negative emotional state indexed by the emission of 22-kHz USVs. To induce the positive emotional arousal, an intracerebral injection of a known D1/D2 agonist R-(-)-apomorphine (3.0 µg/0.3 µl) into the medial nucleus accumbens shell was used, while the negative emotional arousal was induced by intracerebral injection of carbachol (1.0 µg/0.3 µl), a known broad-spectrum muscarinic agonist, into the anterior hypothalamic-medial preoptic area. Our results demonstrated that initiation of a positive emotional state was able to significantly decrease the magnitude of subsequently expressed negative emotional state measured by the number of emitted 22-kHz USVs. The results suggest the neurobiological substrates that initiate positive emotional state antagonize the brain regions that initiate negative emotional states.

Anorexia increases microglial density and cytokine expression in the hippocampus of young female rats

Publication date: Available online 25 January 2019

Source: Behavioural Brain Research

Author(s): Durairaj Ragu Varman, Mayra Macedo-Mendoza, Francisco Emmanuel Labrada-Moncada, Pamela Reyes-Ortega, Teresa Morales, Ataúlfo Martínez-Torres, Daniel Reyes-Haro

Abstract

Anorexia by osmotic dehydration is an adaptive response to hypernatremia and hyperosmolaemia induced by ingestion of a hypertonic solution. Dehydration-induced anorexia (DIA) reproduces weight loss and avoidance of food, despite its availability. By using this model, we previously showed increased reactive astrocyte density in the rat dorsal hippocampus, suggesting a pro-inflammatory environment where microglia may play an important role. However, whether such anorexic condition increases a pro-inflammatory response is unknown. The aim of this study was to test if DIA increases microglial density in the dorsal hippocampus, as well as the expression of pro-inflammatory cytokines tumor necrosis alpha (TNF-α), interleukin 6 (IL-6) and interleukin 1 beta (IL-1β) in the hippocampus of young female rats. Our results showed that DIA significantly increased microglial density in CA2-CA3 and dentate gyrus (DG) but not in CA1. However, forced food restriction (FFR) only increased microglial density in the DG. Accordingly, the activated/resting microglia ratio was significantly increased in CA2-CA3 and DG, in DIA and FFR groups. Finally, western blot analysis showed increased expression of IBA1, TNF-α, IL-6 and IL-1β in the hippocampus of both experimental groups. We conclude that anorexia triggers increased reactive microglial density and expression of TNF-α, IL-6 and IL-1β; this environment may result in hippocampal neuroinflammation.

ABSTRACT

Parkinson's disease (PD) exhibits sexual differences in susceptibility and pathogenesis in humans, with a high incidence in men and a high severity of motor symptoms in male rodents. Furthermore, studies showed that the administration of low dose of reserpine (RES) induces a progressive appearance of motor alterations similar with parkinsonism in male rodents. Here, we investigated sex differences in motor deficits and tyrosine hydroxylase (TH) immunoreactivity induced by a progressive model of parkinsonism. Gonadally intact male and female Wistar rats and ovariectomized female rats received 15 subcutaneous injections (s.c.) every other day of 0.1 mg / kg of RES or vehicle. The repeated administration of low doses of RES (0.1 mg/kg) produces sexually dimorphic impairments on motor performance (catalepsy and open field test). Intact and ovariectomized females were more resistant to the deleterious effect of repeated administration of reserpine in the early, but this resistance in intact female disappears over time. However, intact females showed a reduction of the TH immunoreactivity in substantia nigra pars compacta, but not in ventral tegmental area and dorsal striatum. These results suggest a possible application of this model in the study of sexual dimorphism throughout the progression of PD.

Tissue sodium concentration and sodium T1 mapping of the human brain at 3 T using a Variable Flip Angle method

Publication date: Available online 26 January 2019

Source: Magnetic Resonance Imaging

Author(s): Arthur Coste, Fawzi Boumezbeur, Alexandre Vignaud, Guillaume Madelin, Kathrin Reetz, Denis Le Bihan, Cécile Rabrait-Lerman, Sandro Romanzetti

Abstract
Purpose

The state-of-the-art method to quantify sodium concentrations in vivo consists in a fully relaxed 3D spin-density (SD) weighted acquisition. Nevertheless, most sodium MRI clinical studies use short-TR SD acquisitions to reduce acquisition durations. We present a clinically viable implementation of the Variable Flip Angle (VFA) method for robust and clinically viable quantification of total sodium concentration (TSC) and longitudinal relaxation rates in vivo in human brain at 3 T.

Methods

Two non-Cartesian steady-state spoiled ultrashort echo time (UTE) scans, performed at optimized flip angles, repetition time and pulse length determined under specific absorption rate constraints, are used to simultaneously compute T1 and total sodium concentration (TSC) maps using the VFA method. Images are reconstructed using the non-uniform Fast Fourier Transform algorithm and TSC maps are corrected for possible inhomogeneity of coil transmission and reception profiles. Fractioned acquisitions are used to correct for potential patient motion. TSC quantifications obtained using the VFA method are validated at first in comparison with a fully-relaxed SD acquisition in a calibration phantom. The robustness of similar VFA acquisitions are compared to the short-TR SD approach in vivo on seven healthy volunteers.

Results

The VFA method resulted in consistent TSC and T1 estimates across our cohort of healthy subjects, with mean TSC of 38.1 ± 5.0 mmol/L and T1 of 39.2 ± 4.4 ms. These results are in agreement with previously reported values in literature TSC estimations and with the predictions of a 2-compartment model. However, the short-TR SD acquisition systematically underestimated the sodium concentration with a mean TSC of 31 ± 4.5 mmol/L.

Conclusion

The VFA method can be applied successfully to image sodium at 3 T in about 20 min and provides robust and intrinsically T1-corrected TSC maps.

Eigenvector-based SPIRiT Parallel MR Imaging Reconstruction based on ℓp pseudo-norm Joint Total Variation

Publication date: Available online 25 January 2019

Source: Magnetic Resonance Imaging

Author(s): Jizhong Duan, Zhongwen Bao, Yu Liu

Abstract

Parallel Magnetic Resonance (MR) imaging is a well-established acceleration technique based on the spatial sensitivities of array receivers. Eigenvector-based SPIRiT (ESPIRiT) is a new parallel MR imaging reconstruction method that combines the advantages of the SENSE and GRAPPA methods. It estimates multiple sets of the sensitivity maps from the calibration matrix that is constructed from the auto-calibration data. To improve the quality of the reconstructed image, we introduced the Total Variation (TV) and p pseudo-norm Joint TV (pJTV) regularization terms to the ESPIRiT model for parallel MR imaging reconstruction, which were solved by using the Operator Splitting (OS) method. The resulting denoising problems with the TV and pJTV regularization terms were solved by exploiting the majorization minimization method. Simulation experiments on two in vivo data sets demonstrated that the proposed OS algorithm with the TV regularization term (OSTV) and OS algorithm with the pJTV regularization term (OSpJTV) outperformed the conventional method with the 1 regularization term in terms of SNR and NRMSE. And the OSpJTV algorithm was slightly superior to the OSTV algorithm with the TV regularization term.

Sonophotocatalytic treatment of rhodamine B using visible-light-driven CeO 2 /Ag 2 CrO 4 composite in a batch mode based on ribbon-like CeO 2 nanofibers via electrospinning

Abstract

CeO2/Ag2CrO4 composite photocatalyst was successfully fabricated using electrospinning and calcination and chemical precipitation method based on CeO2 ribbon-like fibers and characterized by field-emission scanning electron microscopy (FESEM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), UV–Vis diffuse reflectance spectroscopy (DRS) and Fourier-transform infrared spectroscopy (FT-IR). The as-obtained CeO2/Ag2CrO4 composite used photocatalytic performance in the sonophotodegradation of rhodamine B in aqueous solution under visible-light (LED) irradiation. DRS analysis illustrates that CeO2/Ag2CrO4 composite exhibited enhanced absorption in the visible region-attributed CeO2 nanofibers. The effect of four effective parameters including initial concentration of rhodamine B (RhB), photocatalyst dosage, pH, and irradiation time was studied and optimized using central composite design. The kinetic studies confirmed ability of pseudo first-order reaction based on the Langmuir–Hinshelwood model for fitting empirical data, while its rate constant (kobs), L–H rate constants (kr), and L–H adsorption constants (KA) were 0.0449 min−1, 11.66 mg L−1 min−1 and 1.09E−3 mg L−1, respectively. The enhanced photocatalytic activity could be ascribed to the ultrasound field and formation of a heterojunction system among CeO2 and Ag2CrO4, which lead to a better mass transfer and higher efficiency of charge electron–hole separation, respectively.

Chironomid genera distribution related to environmental characteristics of a highly impacted basin (Argentina, South America)

Abstract

The objective of the present study was to investigate the responses of the chironomid communities (Diptera: Chironomidae) to environmental variables in four moderately and highly disturbed rivers located in one of the most degraded watersheds in South America. Sampling campaigns were carried out during 2014–2016 in four sites of the Matanza-Riachuelo basin. The physical-chemical and hydrological variables were measured and, the ecological indices were calculated and evaluated by ANOVA. The responses of Chironomidae to the environmental variables were evaluated by redundancy analysis (RDA), and the sampling sites were grouped according to the populations of chironomids and the main environmental variables. Finally, the Spearman correlation was made to determine which of these variables were significant. In total, 13 chironomid taxa were found in 36 samples during the study period. The greatest density registered belongs to Rheotanytarsus and Cricotopus. The ANOVA detected the greatest Chironomidae density and taxonomic richness in the sites with agricultural-urban impact. The changes in the distribution of Rheotanytarsus, Thienemanniella, and Polypedilum were mainly explained by the increase in current velocity, organic matter, and hardness, and the decrease of NH3 and BOD. On the other hand, Goeldichironomus, Chironomus, Parachironomus, Dicrotendipes, and Cricotopus were explained by the increase in conductivity, dissolved oxygen, and temperature, and the decrease of the variables NO3, BOD, and Cu. In addition to this, the sites with urban-agricultural impact were clearly separated from sites with urban-industrial impact. The last one was more related to the increase in BOD, Cu, and NO3 that indicates moderate to poor water quality. In conclusion, we can infer that the physical and chemical variables are correlated with changes in the structure and distribution of the chironomid community and there are genera that respond differently at high and intermediate situations of disturbances. This knowledge contributes to the execution of strategies for the conservation and restoration of the lotic ecosystems.

Effects of fertilizer type and rate on summer maize grain yield and ammonia volatilization loss in northern China

Abstract

Purpose

In this study, we analyzed the effects of different maize varieties with nitrogen utilization efficiency, fertilizer type, and rate on the ammonia volatilization emission of farmland. Aimed to seek the best matching method to improve grain yield and fertilizer utilization efficiency of summer maize simultaneously.

Materials and methods

In field experiments, we choose two maize varieties with different nitrogen utilization efficiency (Zhengdan958, Z and Lainong14, L) as material. Set four different fertilizer treatments (200 kg N hm−2 inorganic fertilizer (U1), 100 kg N hm−2 inorganic fertilizer (U2), 200 kg N hm−2 organic fertilizer (M1), and 100 kg N hm−2 organic fertilizer (M2) to study their effect on NH3 emission and loss, maize grain yield, and nitrogen accumulation.

Results and discussion

Ammonia volatilization accounted for 8.61–21.68% of applied N. Under the same variety, ammonia volatilization accumulation after fertilization was as follows: U1 > U2 > M1 > M2. Ammonia volatilization rates increased first and then gradually decreased after the fertilization. The ammonia volatilization loss and cumulative loss increased due to increased nitrogen fertilizer application rate. The average nitrogen accumulation and harvest index of 200 kg N hm−2 N treatments were higher than 100 kg N hm−2 N treatments, and the difference between the inorganic fertilizer and organic fertilizer was not significant. In 2016 and 2017, the average yield of Zhengdan958 was 11,758.79 kg hm−2, which was 15.78% higher than that of Lainong14, and the difference between the two fertilizer types was not significant. The average yield of 200 kg N hm−2 N treatment was 11,959.42 kg hm−2, which was 20.13% higher than those of 100 kg N hm−2 N treatment.

Conclusions

By changing the type of fertilizer, replacing chemical fertilizers with organic fertilizer can reduce the loss of ammonia volatilization and promote the synergistic improvement to yield and resource utilization efficiency. Among them, using nitrogen-efficient varieties and using organic fertilizer instead of chemical fertilizer was beneficial to reduce the loss of ammonia volatilization, increase the accumulation of nitrogen, and promote the growth of maize to obtain high yield.

The role of unilateral nasal inspiratory peak flow in nasal obstruction‐ a study of seventy patients undergoing septorhinoplasty surgery

Abstract

Nasal Inspiratory Peak Flow (NIPF) poorly correlates with subjective patient reported outcomes (PROMs) following functional septorhinoplasty.

The aim of this study is to determine whether unilateral NIPF correlates with PROMs.

The study demonstrates significant improvement in objective and subjective measurements post septorhinoplasty surgery in seventy patients.

There was weak correlation between improvements in bilateral NIPF when compared with changes in the NOSE score.

Whilst unilateral NIPF does not correlate with subjective outcome scores, it is still a useful measure in assessing nasal patency and in patient education.

Association study of cell cycle proteins and human papillomavirus in laryngeal cancer in Chinese Population

Abstract

Objective

To investigate the role of human papillomavirus (HPV) in laryngeal squamous cell carcinoma (LSCC) and analyze the relationship between HPV and the expression of cell cycle‐related proteins.

Design

The study consisted of LSCC between 2005 and 2011 in Tongren Hospital. Clinical data such as age, sex, smoking/ alcohol consumption and TNM stage were collected. HPV DNA and cell cycle‐related proteins were assessed in terms of clinical features.

Setting

Single center study.

Participants

A total of 332 LSCC patients were included in the study.

Main outcome measures

The presence of genotype‐specific HPV DNA was evaluated using PCR‐RDB in formalin‐fixed paraffin‐embedded tissues. All samples were also evaluated for p16INK4A, p21WAF1/CIP1, P53, Cyclin D1, and Ki67 immunohistochemical staining by tissue microarray.

Results

HPV DNA was detected in 45 of 332 (13.55%) patients with LSCC, with HPV‐16 being the predominant genotype. The presence of HPV‐16 DNA was significantly associated with basaloid squamous cell carcinoma and cystic lymph node metastasis (P < 0.05). Of the 332 patients 36 (10.84%) were scored as p16INK4A positivity, and they were more likely to be female (P < 0.05). Cyclin D1‐positivity and p21WAF1/CIP1‐positivity were observed in 60.24% (200/332)and 40.66%(135/332), respectively. In 114 cases (34.33%), LSCCs had moderate‐ to ‐strong p53 accumulation, which was correlated with TNM stage (P < 0.05). HPV‐16 DNA was correlated with p16INK4A, and manifested a higher Ki‐67 labeling index and p21WAF1/CIP1 expression than HPV‐16‐negative tumors (P < 0.05). No relationship was observed between Cyclin D1or P53 expression and HPV‐16 infection (P > 0.05).

Conclusion

HPV DNA was detected in 13.55% patients with LSCC, with HPV‐16 being the predominant genotype and it was correlated with p16INK4A, and manifested a higher Ki‐67 labeling index and p21WAF1/CIP1 expression than HPV‐16‐negative tumors.

Evaluation and optimization of a methodology for the long-term cryogenic storage of Tetradesmus obliquus at − 80 °C

Abstract

Cryopreservation is a common methodology for long-term microalgae storage. Current cryopreservation methods are based on using diverse cryoprotectants and two-step cooling protocols, followed by sample storage at the temperature of liquid nitrogen (− 196 °C). However, the use of this methodology requires a continuous liquid N2 supply as well as facilities with dedicated equipment, which is not affordable for every laboratory. In our work, we report on the successful development of a simple and cost-effective method for the long-term cryogenic storage of Tetradesmus obliquus at temperatures (− 80 °C) used in commonly available deep freezers that are more readily accessible to laboratories. Two procedures were evaluated that were originally devised for other microalgae; this was followed by the optimization of critical parameters such as the sample's microalgal concentration and the cryoprotectant reagent's incubation time. Cell viability was monitored using the survival rates obtained by direct agar plating and the growth recovery times in liquid cultures. Viability-related variables were recorded following different storage times of up to 3 years. The main operational factors involved in the process (cell concentration, incubation time, and storage time) were statistically analyzed with regard to their influence on the survival rate. The statistical analysis showed interdependence (a two-factor interaction) between the cellular concentration and the cryoprotectant's incubation time, on the one hand, and between the incubation time and the storage time on the other. Survival rates above 70% were obtained under optimized conditions after 3 months of storage, along with 20–35% viabilities after 3 years. These results open up the possibility of extending this method to other Scenedesmaceae, or even other microalgal species, and for its use in resource-limited laboratories.

Modeling the effect of the cephalic phase of insulin secretion on glucose metabolism

Abstract

The nervous system has a significant impact in glucose homeostasis and endocrine pancreatic secretion in humans, especially during the cephalic phase of insulin release (CPIR); that is, before a meal is absorbed. However, the underlying mechanisms of this neural-pancreatic interaction are not well understood and therefore often neglected, despite their significance to achieving an optimal glucose control. As a result, the dynamics of insulin release from the pancreas are currently described by mathematical models that reproduce the behavior of the β cells using exclusively glucose levels and other hormones as inputs. To bridge this gap, we have combined, for the first time, metabolic and neural mathematical models in a unified system to reproduce to a great extent the ideal glucoregulation observed in healthy subjects. Our results satisfactorily replicate the CPIR and its impact during the post-absorptive phase. Furthermore, the proposed model gives insight into the physiological interaction between the brain and the pancreas in healthy people and suggests the potential of considering the neural information for restoring glucose control in people with diabetes.

Exact inter-discharge interval distribution of motor unit firing patterns with gamma model

Abstract

Inter-discharge interval distribution modeling of the motor unit firing pattern plays an important role in electromyographic decomposition and the statistical analysis of firing patterns. When modeling firing patterns obtained from automatic procedures, false positives and false negatives can be taken into account to enhance performance in estimating firing pattern statistics. Available models of this type, however, are only approximate and use Gaussian distributions, which are not strictly suitable for modeling renewal point processes. In this paper, the theory of point processes is used to derive an exact solution to the distribution when a gamma distribution is used to model the physiological firing pattern. Besides being exact, the solution provides a way to model the skewness of the inter-discharge distribution, and this may make it possible to obtain a better fit with available experimental data. In order to demonstrate potential applications of the model, we use it to obtain a maximum likelihood estimator of firing pattern statistics. Our tests found this estimator to be reliable over a wide range of firing conditions, whether dealing with real or simulated firing patterns, the proposed solution had better agreement than other models.

Self‐Assembled Gels formed in Deep Eutectic Solvents – Supramolecular Eutectogels with High Ionic Conductivities

This paper reports the ability of 1,3:2,4‐dibenzylidene‐D‐ sorbitol (DBS), a simple, commercially‐relevant compound, to self‐assemble as a result of intermolecular non‐covalent interactions into supramolecular gels in deep eutectic solvents (DESs). The DESs are based on choline chloride combined with alcohols/ureas – DBS forms gels at a loading of 5% wt/vol. Rheology confirms the gel‐like nature of the materials, electron microscopy indicates underpinning nanofibrillar DBS networks and differential scanning calorimetry shows the deep eutectic solvent nature of the liquid‐like phase is retained. The ionic conductivities of the gels are similar to those of the unmodified DESs proving the deep eutectic nature of the ionic liquid‐like phase. Gelation is tolerant of ionic additives Li+, Mg2+ and Ca2+, with the resulting gels having similar conductivities to electrolyte dissolved in the native DES. The low‐molecular‐weight gelator DBS is a low‐cost additive – forming gels in DESs from readily‐available constituents, with conductivity levels suitable for practical applications. We suggest supramolecular eutectogels have potential uses ranging from energy technology to synthesis and catalysis.

Active oxygen enhanced homogeneous nucleation of Li‐metal on ultrathin layered double hydroxide

The development of safe lithium (Li)‐metal anode is crucial for the next‐generation rechargeable batteries. To stabilize Li metal anode, preplanting Li nucleation seeds on lithiophilic substrates is an efficient strategy to regulate initial nucleation process of Li‐metal. Herein, we first reported the activated ultrathin layered double hydroxide (U‐LDHs) as a promising lithiophilic 2D material to realize the uniform deposition of Li metal. The experimental studies and DFT calculations reveal that the active oxygen on U‐LDHs provides abundent atomic‐scale active sites for Li homogeneous nucleation and plating. Moreover, the lithiophilic property of active oxygen is also related to its coordination environments. This work opens up an opportunity to more accurate regulation and understanding of Li nucleation from atomic‐scale based on 2D ultrathin materials.

A Photoresponsive Stiff‐Stilbene Ligand Fuels the Reversible Conformational Unfolding of G‐Quadruplex DNA

The polymorphic nature of G‐quadruplex (G4) DNA structures points to a range of potential applications in nanodevices and an opportunity to control G4 in biological settings. Light is an attractive means for the regulation of oligonucleotide structure as it can be delivered with high spatiotemporal precision. However, surprisingly little attention has been devoted towards the development of ligands for G4 that allow photoregulation of G4 folding. We report a novel G4‐binding chemotype derived from stiff‐stilbene. Surprisingly however, whilst the ligand induces high stabilization in the potassium form of human telomeric DNA, it causes the unfolding of the same G4 sequence in sodium buffer. This effect can be reversed on‐demand by irradiation with 400 nm light through deactivation of the ligand by photo‐oxidation. By fueling the system with the photolabile ligand, the conformation of G4 DNA was switched five times.

Promoting the Outgrowth of Neurites on Electrospun Microfibers by Functionalization with Electrosprayed Microparticles of Fatty Acids

Controlling the outgrowth of neurites is important for enhancing the repair of injured nerves and understanding the development of nervous systems. Here we report a simple strategy for enhancing the outgrowth of neurites through a unique integration of topographical guidance and chemical cue. We use electrospray to easily functionalize the surface of a substrate with microparticles of natural fatty acids at a controllable density. Through a synergistic effect from the surface roughness arising from the microparticles and the chemical cue offered by the fatty acids, the outgrowth of neurites from PC12 cells is greatly enhanced. We also functionalize the surfaces of uniaxially aligned, electrospun microfibers with the microparticles and further demonstrate that the substrates can guide and enhance directional outgrowth of neurites from both PC12 multicellular spheroids and chick embryonic dorsal root ganglia bodies. On the aligned microfibers decorated with an optimal density of the microparticles, the outgrowth of neurites is maximized. This work offers a simple and practical system to design substrates for controlling neurite outgrowth, holding promise for applications in enhancing neural tissue regeneration and understanding neuronal development.

The cyclic phosphoramidite reagent c‐PyPA enables iterative polyphosphorylations

An iterative polyphosphorylation approach is described, which is based on a phosphoramidite (P‐amidite) derived reagent (c‐PyPA) obtained from the cyclization of pyrophosphate with a reactive diisopropylamino dichlorophosphine. This type of reagent is unprecedented as it represents a reactive P‐amidite without protecting groups. The reagent proved to be stable in solution over several weeks. Its utility is described in the context of iterative monodirectional and bidirectional polyphosphorylations. The ensuing functionalized cyclotriphosphate can be opened with a variety of nucleophiles providing ready access to diverse functionalized polyphosphate chains of defined length with several tags, including both P‐N and P‐O labels. Their interaction with exo‐ and endopolyphosphatases is described.

Ni‐Catalyzed Asymmetric Reductive Diarylation of Vinylarenes

A Ni‐catalyzed asymmetric diarylation reaction of vinylarenes represents a compelling method for preparing chiral α,α,β‐triarylated ethane scaffolds, which exist in a number of biologically active molecules. The use of reducing conditions with aryl bromides as coupling partners avoids stoichiometric organometallic reagents and tolerates a broad range of functional groups. The application of an N‐oxyl radical as a ligand to Ni catalysts represents a novel approach to facilitate Ni‐catalyzed cross‐coupling reactions.

Predicting the limit of intramolecular H‐Bonding with classical molecular dynamics

The energetics of intramolecular recognition processes are governed by the balance of pre‐organization and flexibility that is often difficult to measure and hard to predict. Here, by using state‐of‐the‐art classical molecular dynamics simulations, we predict and quantify the effective strength of intramolecular interactions between H‐bond donor and acceptor sites separated by a variable alkyl linker—in a variety of solvents and including crowded solutions. The fine balance of entropic and enthalpic contributions posits a solvent‐dependent limit to the occurrence of intramolecular H‐bonding. Nevertheless, H‐bond free energies are rigidly shifted among different solvents with, for example, a systematic ~13 kJ/mol gap between water and chloroform. Molecular crowding shows little effects on thermodynamic equilibrium but it induces pronounced variations on H‐bond kinetics. The results are in quantitative agreement with available experimental measurement (in chloroform) and showcase a general strategy to interrogate molecular interactions in different environments, extending the limits of current experiments towards the prospective prediction of H‐bond interactions in pharmaceutical, agrochemical, and technological contexts.

Isolation and Synthesis of Novel Meroterpenoids from Rhodomyrtus tomentosa: Investigation of a Reactive Enetrione Intermediate

Rhodomyrtusials A–C (5–7), the first examples of triketone‐sesquiterpene meroterpenoids featuring a unique 6/5/5/9/4 fused pentacyclic ring system were isolated from Rhodomyrtus tomentosa, along with several biogenetically‐related dihydropyran isomers (8–11). Compounds 5, 6, and 10 showed acetylcholinesterase (AChE) inhibitory activity. Structures of the isolates were unambiguously established by a combination of spectroscopic data, ECD analysis, and total synthesis. Bioinspired total syntheses of 5, 7, and 8–11 were achieved in six steps utilizing a reactive enetrione intermediate generated in situ from a readily available hydroxy‐endoperoxide precursor.

Ethanol‐Precipitable, Silica‐Passivated Perovskite Nanocrystals Incorporated into Polystyrene Microspheres for Long‐Term Storage and Reusage

Angewandte Chemie International Edition Ethanol‐Precipitable, Silica‐Passivated Perovskite Nanocrystals Incorporated into Polystyrene Microspheres for Long‐Term Storage and Reusage

A new method for preparing silica‐passivated perovskite nanocrystals that are precipitable by polar solvents without destroying their surface chemistry or losing quantum yield, and can also be encapsulated into non‐crosslinked polystyrene microspheres for long‐term storage against moisture and reusage.


Abstract

Perovskite nanocrystals (PNCs) are emerging luminescent materials due to their fascinating physic‐optical properties. However, their sensitive surface chemistry with organic polar solvents, oxygen, and moisture greatly hinders their developments towards practical applications. Herein we promote silica‐passivated PNCs (SP‐PNCs) by in situ hydrolyzing the surface ligands of (3‐aminopropyl) triethoxysilane. The resultant SP‐PNCs possesses a high quantum yield (QY) of 80 % and are precipitable by polar solvents, such as ethanol and acetone, without destroying their surface chemistry or losing QY, which offers an eco‐friendly and efficient method for separation, purification, and phase transfer of PNCs. Moreover, we further promoted a swelling–deswelling encapsulation process to incorporate the as‐made SP‐PNCs into non‐crosslinked polystyrene microspheres (PMs), which can largely increase the stability of the SP‐PNCs against moisture for long‐term storage.

Organophosphorus‐Catalyzed Deoxygenation of Sulfonyl Chlorides: Electrophilic (Fluoroalkyl)sulfenylation by PIII/PV=O Redox Cycling

Angewandte Chemie International Edition Organophosphorus‐Catalyzed Deoxygenation of Sulfonyl Chlorides: Electrophilic (Fluoroalkyl)sulfenylation by PIII/PV=O Redox Cycling

Oat field: A method for electrophilic sulfenylation by organophosphorus‐catalyzed deoxygenative O‐atom transfer (OAT) from sulfonyl chlorides is reported. This C−S bond‐forming reaction is catalyzed by 1 (phosphetane) in conjunction with a hydrosilane terminal reductant to afford sulfenyl electrophiles, including valuable trifluoromethyl, perfluoroalkyl, and heteroaryl derivatives.


Abstract

A method for electrophilic sulfenylation by organophosphorus‐catalyzed deoxygenative O‐atom transfer from sulfonyl chlorides is reported. This C−S bond‐forming reaction is catalyzed by a readily available small‐ring phosphine (phosphetane) in conjunction with a hydrosilane terminal reductant to afford a general entry to sulfenyl electrophiles, including valuable trifluoromethyl, perfluoroalkyl, and heteroaryl derivatives that are otherwise difficult to access. Mechanistic investigations indicate that the twofold deoxygenation of the sulfonyl substrate proceeds by the intervention of an off‐cycle resting state thiophosphonium ion. The catalytic method represents an operationally simple protocol using a stable phosphine oxide as a precatalyst and exhibits broad functional‐group tolerance.

From Lead Iodide to a Radical Form Lead‐Iodide Superlattice: High Conductance Gain and Broader Band for Photoconductive Response

Angewandte Chemie International Edition From Lead Iodide to a Radical Form Lead‐Iodide Superlattice: High Conductance Gain and Broader Band for Photoconductive Response

Lead the way: The first lead‐iodide superlattice constructed from non‐ionic organic molecules and PbI2 through van der Waals interactions is a new type of inorganic–organic hybrid and has a radical and a non‐radical form. The radical form has an almost five orders of magnitude greater conductivity and broader band photoconductive response than that of the non‐radical form or pure PbI2.


Abstract

Superlattice materials offer new opportunities to modify optical and electrical properties of recently emerging 2D materials. The insertion of tetraethylbenzidine (EtDAB) into interlamination of the established 2D PbI2 semiconductor through a mild solution method yielded the first lead iodide superlattice, EtDAB⋅4PbI2 (EtDAB=tetraethylbenzidine), with radical and non‐radical forms. The non‐radical form has a non‐ionic structure that differs from the common ionic structures for inorganic–organic hybrid lead halides. The radical form shows five orders of magnitude greater conductance and broader photoconductive response range (UV/Vis → UV/Vis‐IR), than pure PbI2 and the non‐radical form of the superlattice.

Polybismuthide Anions as Ligands: The Homoleptic Complex [(Bi7)Cd(Bi7)]4− and the Ternary Cluster [(Bi6)Zn3(TlBi5)]4−

Angewandte Chemie International Edition Polybismuthide Anions as Ligands: The Homoleptic Complex [(Bi7)Cd(Bi7)]4− and the Ternary Cluster [(Bi6)Zn3(TlBi5)]4−

A coordination compound with intact Bi73− ligands, namely the homoleptic complex [(Bi7)Cd(Bi7)]4−, and the ternary cluster [(Bi6)Zn3(TlBi5)]4− were prepared through in situ degradation of the binary Zintl anion (TlBi3)2−. The compounds provide a glimpse into a possible formation pathway of the polycyclic polybismuthide, the follow‐up chemistry of which has been unprecedented to date. Both title compounds were further studied by means of DFT methods.


Abstract

We present the results from a reactivity study of the binary anion (TlBi3)2− towards Group 12 metal compounds MPh2 (M=Zn, Cd, Hg) to gain access to coordination compounds of polycyclic polypnictide molecules such as Bi73− or Bi113−. The coordination chemistry of these polybismuthide cages has been unprecedented to date, while it has been known for a long time for the lighter Group 15 anions Pn73− (Pn=P, As, Sb). The use of (TlBi3)2−, previously shown to release Tl under certain conditions in situ, resulted in the formation of the first heterometallic polyanion in which a nortricyclane‐type polybismuthide coordinates a transition‐metal atom, [(Bi7)Cd(Bi7)]4−. Reactions with the lighter Group 12 metal precursor yielded the uncommon ternary cluster [(Bi6)Zn3(TlBi5)]4−, most likely representing a reaction intermediate, and at the same time hinting at the formation of the nortricyclane‐shaped cage. Quantum‐chemical studies provide deeper insight into the stability trends of the [(E7)M(E7)]4− anion family and reveal a complex bonding situation in [(Bi6)Zn3(TlBi5)]4−, which features both localized and multi‐center bonding.

Photoredox‐Catalyzed Cyclobutane Synthesis via a Deboronative Radical Addition–Polar Cyclization Cascade

Photoredox‐catalyzed methylcyclobutanations of alkylboronic esters are described. The reactions proceed via single‐electron transfer induced deboronative radical addition to an electron‐deficient alkene followed by single‐electron reduction and polar 4‐exo‐tet cyclization with a pendant alkyl halide. Key to the success of the methodology was the use of easily oxidizable arylboronate complexes. Structurally diverse cyclobutanes are shown to be conveniently prepared from readily available alkylboronic esters and a range of haloalkyl alkenes. The mild reactions display excellent functional group tolerance, and the radical addition–polar cyclization cascade also enables the synthesis of 3‐, 5‐, 6‐, and 7‐membered rings.

A Stable Lithium–Oxygen Battery Electrolyte Based on Fully Methylated Cyclic Ether

Angewandte Chemie International Edition A Stable Lithium–Oxygen Battery Electrolyte Based on Fully Methylated Cyclic Ether

Full methyl jacket: A fully methylated cyclic ether 4,4,5,5‐hexamethyl‐1,3‐dioxolane is used as an electrolyte solvent for Li–O2 batteries. It exhibits excellent stability in the presence of superoxide or singlet oxygen because all the active α‐H atoms are substituted with methyl groups. The cycling performance is 4 times greater that of conventional ether electrolytes.


Abstract

Ether‐based electrolytes are commonly used in Li–O2 batteries (LOBs) because of their relatively high stability. But they are still prone to be attacked by superoxides or singlet oxygen via hydrogen abstract reactions, which leads to performance decaying during long‐term operation. Herein we propose a methylated cyclic ether, 2,2,4,4,5,5‐hexamethyl‐1,3‐dioxolane (HMD), as a stable electrolyte solvent for LOBs. Such a compound does not contain any hydrogen atoms on the alpha‐carbon of the ether, and thus avoids hydrogen abstraction reactions. As the result, this solvent exhibits excellent stability with the presence of superoxide or singlet oxygen. In addition the CO2 evolution during charge process is prohibited. The LOB with HMD‐based electrolyte was able to run up to 157 cycles, 4 times more than with 1,3‐dioxolane (DOL) or 1,2‐dimethoxyethane (DME) based electrolytes.
