AbstractBackground and AimsIt is being increasingly reported that the Cranio Facial Development Protein 1 (CFDP1) plays a significant role in the onset and progression of tumors. Nonetheless, the underlying mechanisms associated with CFDP1 that contribute to hepatocellular carcinoma (HCC) and the specific biological role of CFDP1 remain vague.MethodsThe Gene Expression Omnibus (GEO) database was analyzed to obtain the gene expression profiles as well as the matching clinical data of HCC patients. The gene co‐expression network was developed by means of weighted gene co‐expression network analysis (WGCNA) to screen for possible biomarkers that could be used for the purpose of predicting prognosis. The Cancer Genome Atlas (TCGA) and Gene Expression Profile Interaction Analysis (GEPIA) databases were used to assess the relationship between survival and expression. In addition, we identified the underlying mechanism associated with CFDP1 by analyzing the KEGG pathway database, applying the GSEA and GeneCards analysis method. We performed a sequence of experiments (in vivo and in vitro) for the purpose of investigating the specific function of CFDP1 in liver cancer.ResultsThe obtained results revealed high expression of CFDP1 in HCC tissues and cell lines. A positive correlation between the overexpression of CFDP1 and the adverse clinicopathological features was observed. Moreover, we observed that the low recurrence‐free survival and overall survival were associated with CFDP1 overexpression. In addition, GeneCards and GSEA analysis showed that CFDP1 may interact with NEDD4 and participate in PTEN regulation. Meanwhile, CFDP1 can promote the malignant development of liver cancer in vivo and in vitro. The western blotting technique was also employed so as to examine the samples, and the findings demonstrated that CFDP1 enhanced the malignancy of HCC via the NEDD4‐mediated PTEN/PI3K/AKT pathway.ConclusionWe highlighted that CFDP1 played an oncogenic role in HCC and was identified as a possible clinical prognostic factor and a potential novel therapeutic target for HCC.

AbstractBackground and ObjectivesComposite flour (CF) from cereals and legumes has been used to formulate plant‐based and/or gluten‐free food products. Fundamental knowledge regarding the properties of CF is required to formulate food products with desirable qualities. This study aimed to investigate the pasting properties, thermal properties, and viscoelastic behavior of CF, containing rice flour (RF), mung bean flour (MF), and mung bean protein concentrate (MPC). The protein contents of the CF were 17.6%‐23.6% on a wet basis.FindingsThe CF containing the highest proportion of RF had the highest pasting temperature, peak viscosity, breakdown, setback, and melting enthalpy of retrograded amylopectin. The deconvoluted thermogram from differential scanning calorimetry (DSC) clearly distinguished the endotherms that arose from starch gelatinization, protein denaturation, and melting of the amylose−lipid complex. The gelatinization endotherm of CF was mainly governed by RF. CF containing a higher proportion of RF and MPC had stronger elastic behavior.ConclusionsThe type and composition of the flour greatly affected the physicochemical and viscoelastic properties of the CF. RF played an important role in the pasting and thermal properties of the CF samples. Combining RF and MPC could be used to enhance the elastic behavior of dough from CF systems.Significance and NoveltyDeconvoluted DSC peaks provided insight into the multiple thermal transitions that occurred during the processing of CF‐based foods. The overall results from this study could help in the formulation of food containing rice−mung bean CF in excess water or in a dough system.

AbstractIn oxidative esterification of methacrolein to methyl methacrylate, mass transfer of O2 and N2 in methanol is of vital importance for the determination of reaction kinetics and design of industrial units. The mass transfer coefficients kL of O2 and N2 in methanol were determined by the decreasing‐pressure method in a gas‐liquid stirred reactor at temperatures ranging from 298.15 to 333.15 K, pressures ranging from 0.5 to 1.2 MPa, and agitation speeds ranging from 100 to 200 rpm. It could be shown that kL‐O2 and kL‐N2 increased with increasing temperature and agitation speed, but did not change significantly with partial pressure. On the basis of the experimental results, theoretical and empirical equations were proposed. This work provides an example of a study on the mass transfer of gases in a liquid.

AbstractWe have shown solvent‐ and substrate‐dependent chiral inversion of a few glycoconjugate supramolecules. (Z)‐F‐Gluco, in which d‐glucosamine has been attached chemically to Cbz‐protected l‐phenylalanine at the C terminus, forms a self‐healing hydrogel through intertwining of the nanofibers wherein the gelators undergo lamellar packing in the β‐sheet secondary structures with a single chiral handedness. Dihybrid (Z)‐F‐gluco nanocomposite gel was prepared by in‐situ formation of silver nanoparticles AgNPs in the gel; this enhances the mechanical properties of the composite gel through physical crosslinking without altering the packing pattern. In contrast, (Z)‐L‐gluco bearing an l‐leucine moiety does not form a hydrogel but an organogel. Interestingly, the chiral handedness of the aggregates of (Z)‐L‐gluco can be reversed by choosing suitable solvents. In addition to self‐healing behavior, (Z)‐L‐gluco gel revealed shape persistency. Further, (Z)‐F‐gluco hydrogel is benign, nontoxic, non‐immunogenic, and non‐allergenic in animal cells. AgNP‐loaded (Z)‐F‐gluco hydrogel showed antibacterial activity against both Gram‐positive and Gram‐negative bacteria.

AbstractPeroxygenases selectively incorporate oxygen into organic molecules making use of the environmentally friendly oxidant H2O2 with water being the sole by‐product. These biocatalysts can provide ‘green’ routes for the synthesis of enantioenriched epoxides, which are fundamental intermediates in the production of pharmaceuticals. The peroxyzyme 4‐oxalocrotonate tautomerase (4‐OT), catalysing the epoxidation of a variety of α,β‐unsaturated aldehydes with H2O2, is outstanding because of its independence from any cost‐intensive cofactor. However, its low‐level peroxygenase activity and the decrease in the enantiomeric excess of the corresponding α,β‐epoxy‐aldehydes under preparative‐scale conditions is limiting the potential of 4‐OT. Herein we report the directed evolution of a tandem‐fused 4‐OT variant, which showed an ∼150‐fold enhanced peroxygenase activity compared to 4‐OT wild type, enabling the synthesis of α,β‐epoxy‐aldehydes in milligram‐ and gram‐scale with high enantiopurity (up to 98 % ee) and excellent conversions. This engineered cofactor‐independent peroxyzyme can provide new opportunities for the eco‐friendly and practical synthesis of enantioenriched epoxides at large scale.

Published: July 2022

AbstractThe Nazarov cyclization is investigated in solution and within K12[Ga4L6] supramolecular organometallic cage by means of computational methods. The reaction needs acidic condition in solution but works at neutral pH in the presence of the metallocage. The reaction steps for the process are analogous in both media: (a) protonation of the alcohol group, (b) water loss and (c) cyclization. The relative Gibbs energies of all the steps are affected by changing the environment from solvent to the metallocage. The first step in the mechanism, the alcohol protonation, turns out to be the most critical one for the acceleration of the reaction inside the metallocage. In order to calculate the relative stability of protonated alcohol inside the cavity, we propose a computational scheme for the calculation of basicity for species inside cavities and can be of general use. These results are in excellent agreement with the experiments, identifying key steps of catalysis and providing an in‐depth understanding of the impact of the metallocage on all the reaction steps.

AbstractIn this work, two monomeric magnesium alkyl complexes (1and2) were prepared using bis(phosphino)carbazole framework and among them1has been used as a catalyst for hydroboration of alkenes and alkynes with pinacolborane (HBpin). A broad variety of aromatic and aliphatic alkenes and alkynes were efficiently reduced. Anti‐Markovnikov regioselective hydroboration of alkenes and alkynes was achieved, which was confirmed by deuterium‐labelling experiments. The work represents the first example of the use of magnesium in homogeneous catalytic hydroboration of alkene with broad substrate scope. Experimental mechanistic investigations and DFT calculations provided insights into the reaction mechanism. Finally, the hydroboration protocol was extended to terpenes.

AbstractProteins are able to irreversibly assemble biologically active ligands from building blocks bearing complementary reactive functions due their spatial proximity, through a kinetic target‐guided synthetic process (also named in situ click chemistry). Although linkages thus formed are mostly passive, some of them have shown to significantly contribute to the protein binding through for instance hydrogen bonding and stacking interactions. Biocompatible reactions and click chemistry are a formidable source of inspiration for developing such new protein‐directed ligations. This study reports a proximity‐induced thiol‐yne synthesis of carbonic anhydrase inhibitors. Not only this example widens the arsenal of kinetic target‐guided synthesis (KTGS) eligible reactions, but the obtained product displayed unsuspected photophysical properties. The corresponding vinyl sulfide linkage conjugated to a coumarin core proved to be engaged in a monodirectional Z to E photoisomerization process. Further investigations guided by theoretical calculations showed that fine‐tuning of the nature of the substituents on the coumarin moiety allows to obtain a bidirectional photochemical process, thus discovering a new photoswitching moiety, displaying moreover fluorescence properties. Due to the spectral tunability of coumarin derivatives, this work should open new opportunities for the design of vinyl sulfide‐based photoswitch systems with modular photophysical properties.

AbstractBackgroundPediatric hepatocellular carcinoma (HCC) is a group of liver cancers whose mechanisms behind their pathogenesis and progression are poorly understood.AimWe aimed to identify alterations in the expression of miRNAs and their putative target mRNAs in not only tumor tissues of patients with pediatric HCC but also in corresponding non‐tumorous background livers by using liver tissues without underlying liver disease as a control.Methods and resultsWe performed a small‐scale miRNA and mRNA profiling of pediatric HCC (consisting of fibrolamellar carcinoma [FLC] and non‐FLC HCC) and paired liver tissues to identify miRNAs whose expression levels differed significantly from control livers without underlying liver disease. ToppMiR was used to prioritize both miRNAs and their putative target mRNAs in a gene‐annotation network, and the mRNA profile was used to refine the prioritization. Our analysis generated prioritized lists of miRNAs and mRNAs from the following three sets of analyses: (a) pediatric HCC versus control; (b) FLC versus control; and (c) corresponding non‐tumorous background liver tissues from the same patients with pediatric HCC versus control. No liver disease liver tissues were used as the control group for all analyses. Many miRNAs whose expressions were deregulated in pediatric HCC were consistent with their roles in adult HCC and/or other non‐hepatic cancers. Our gene ontology analysis of target mRNAs revealed enrichment of biological processes related to the sustenance and propagation of cancer and significant downregulation of metabolic processes.ConclusionOur pilot study indicates that alterations in miRNA–mRNA networks were detected in not only tumor tissues but also corresponding non‐tumorous liver tissues from patients with pediatric HCC, suggesting multi‐faceted roles of miRNAs in disease progression. Our results may lead to novel hypotheses for future large‐scale studies.
An efficient stable node selection based on Garson's pruned recurrent neural network and MSO model for multipath routing in MANET

Published: July 2022

AbstractIn mobile ad hoc network, the routing task is considered to be more complicated issue. In order to find efficient route in MANET, the positions of each stable node in the network is identified initially. The main contribution of this paper is to identify the locations of neighboring nodes in MANET for the establishment of multi path routing in diverse mobility patterns. It also handles packet scheduling to balance the load as well as data forwarding with less communication time. The proposed work explains four phases such as stable node prediction, stability determination, route exploration, and packet dissemination. At first, the stable nodes are identified using recurrent neural network along with modified seagull optimization approach. By means of Garson's pruning based recurrent neural network accompanied with modified sea gull optimization (RMSG) algorithm, the stable neighbors are chosen. The network routing is formed by interconnecting the stable nodes from the source to the destination. When a routing link failure happens, the route recovery process will be initiated. Thus, the data packets are broadcasted in multi‐paths without any intervention. The measures namely packet delivery ratio, throughput, end‐to‐end delay, routing overhead, optimal path selection, and energy consumption are utilized to evaluate the performance of proposed approach. The experimental analysis proved that the proposed approach well performed than other compared existing approaches.

Authors: Lambert Ethan C. , Smith Cameron L. , Compton Robert N. , Hammer Nathan I. 
Published: July 2022

AbstractGuest‐host Raman under liquid nitrogen spectroscopy (GHRUNS) is introduced whereby solid‐state guest molecules are isolated inside cage‐like host environments for the facile acquisition of their Raman spectra. This convenient method features reduced fluorescence, the analysis of populations in their ground states, and increased signal to noise ratios. Samples are also preserved through the reduction of thermal degradation and oxidation. To demonstrate the benefits of this new method, Raman spectra of the ubiquitous molecule C60 inside a cage of water ice are presented. Using this technique, a new normal mode of C60 is elucidated. The GHRUNS methodology is of interest to those seeking to acquire and characterize the vibrational spectra, structure, and properties of emissive, air‐sensitive molecules.
A novel fuzzy‐extended Kalman filter‐ampere‐hour (F‐EKF‐Ah) algorithm based on improved second‐order PNGV model to estimate state of charge of lithium‐ion batteries

Published: July 2022

AbstractAiming at the problem that it is difficult to accurately estimate the state of charge (SOC) of lithium‐ion batteries in the strongly nonlinear interval, a novel algorithm based on a fuzzy control strategy is proposed. It integrates extended Kalman filter (EKF) and ampere‐hour (Ah) integration accurately estimate the SOC of lithium‐ion batteries. First, the algorithm uses the advantage that the EKF algorithm has high estimation accuracy in the nonlinear interval and can solve the problem of the large error caused by the inaccurate initial value of the Ah integral algorithm. Then the fuzzy‐EKF‐Ah (F‐EKF‐Ah) is used to fuse the two algorithms of EKF and Ah integral. The fused algorithm can effectively solve the problems of the cumulative error caused by the sampling accuracy of the Ah integral algorithm and the large estimation error of the EKF algorithm in the strong nonlinear interval. Finally, the equivalent circuit model is used for analysis. The experimental results show that the improved algorithm can achieve high estimation accuracy under three experimental conditions.

Published: July 2022

AbstractThe aim of this study was to elucidate the mechanism underlying the effects of Kukoamine A (KuA) treatment on endotoxin‐induced lung injury/inflammation. The study was performed in lipopolysaccharide (LPS)‐exposed mouse models of lung injury and LPS‐induced alveolar epithelial cell model. Relevant kits were used to detect levels of inflammation‐related indicators, oxidative stress indicators, and mitochondrial function. Hematoxylin and eosin staining was to detect lung injury. Then, C‐C motif chemokine receptor 5 (CCR5) overexpression plasmid was transfected into alveolar epithelial cells to investigate the mechanism of KuA in lung injury. The results showed that LPS induction increased the expression of inflammatory factors, oxidative stress markers, and mitochondrial dysfunction in both animal and cellular models. In the mouse model, KuA treatment improved lung tissue injury, decreased wet‐to‐dry ratio and MPO levels, reduced the expression of inflammatory factors, and ameliorated oxidative stress and mitochondrial dysfunction. The protective effect of KuA in the cell model remained whereas was markedly reversed after CCR5 overexpression. Taken together, KuA might improve LPS‐induced lung injury by inhibiting CCR5. This might also provide a novel theory for KuA in the treatment of lung injury.

Published: July 2022

AbstractDespite significant effort, the complexity of europium(III) luminescence in general – and sample composition in particular – has precluded the publication of standard spectra of specific complexes in aqueous solution. Further, low spectral resolution, weighted averages with contributions from several species, as well as poor reproduction hampers the use of literature data, with the note that high quality data from e. g. Bünzli, Latva, Carnall, Parker, Heller, Balzani and Sabatini is from the pre‐electronic era. Here, luminescence spectra of Eu.DOTA, Eu.EDTA, Eu.DPA1, Eu.DPA2. Eu.DPA3, Eu.DTPA and the Eu(III) aqua ion was determined in samples with known pH and conductivity. The ligand concentrations were varied in a buffered medium (MES) with a significant salt background. In this manner, full complexation could be ensured, while pH and ionic strength were monitored. The spectra corresponding to the complexes were extracted, and the electronic structure of the ground state 7FJ manifold was investigated and contrasted to literature data. All spectroscopic data is made available and we suggest this becomes part of the standard procedure when investigating lanthanide(III) complexes.

AbstractA one‐dimensional (1D) coordination polymer [Co(btca)1/2(mbpy)]n (1, mbpy=4,4′‐Dimethyl‐2,2′‐bipyridyl, H4btca=1,2,4,5‐Benzenetetracarboxylic acid) constructed by a mixed tetracarboxylic‐dipyridyl ligand strategy with a ribbon topology was synthesized and magnetically characterized. Magnetic studies combined with theoretical calculations reveal large easy‐axis magnetic anisotropy of the central Co(II) ions in a highly distorted five‐coordination geometry. Interestingly, field‐induced single‐ion magnet (SIM) behavior was evidenced in the chain compound, making the cobalt(II) coordination ribbon to be the first five‐coordinate SIM chain.

Published: July 2022

AbstractA nanocomposite (Ho2O3NPs/BNT) was synthesized by decorating holmium(III)oxide nanoparticles (H2O3NPs) on bentonite (BNT) through a realizable sonochemical approach for the electrochemical detection of haloperidol (Hlp). A glassy carbon electrode was modified with this nanocomposite. The Ho2O3NPs/BNT modified electrode outperformed bare and other modified electrodes in terms of electrochemical performance for Hlp detection in a pH 8.0 phosphate buffer. The proposed electrochemical platform showed a wide linear range (0.01 μM–24 μM), low detection limit (2.4 nM), and high sensitivity by square wave voltammetry. In addition, the proposed electrochemical sensor met the clinical criteria in terms of stability, selectivity, and repeatability.
