Published: April 2022

AbstractBackground and ObjectivesHarvest moisture content (HMC) and milling duration are important factors that influence milled rice quality. The goal of this study is to determine the effect of HMC and milling duration on the physicochemical properties of long grain and medium grain microwave‐dried rice. A long‐grain hybrid rice cultivar (XL753) and a medium‐grain rice cultivar (Titan) with initial HMCs of 16%, 18%, and 20% (wet basis) were sourced from rice farms in Arkansas, USA. The rice samples were dried with the 915 MHz industrial microwave at a specific energy of 525 kJ/[kg‐grain]. The control samples were dried with natural air in an equilibrium moisture content chamber set at 25°C and 56% relative humidity. Following drying, the samples were milled at milling durations of 30, 45, and 60 s, and physicochemical properties were determined.FindingsHMC had significant (p < .05) impacts on head rice yield, crude protein content, and final viscosity of microwave‐dried rice for both cultivars. There were strong positive correlations (Titan: 0.86, XL753: 0.88) between HMC and head rice yield and negative correlations (Titan: −0.85, XL753: −0.62) between HMC and final viscosity of microwave‐dried rice. Milling duration significantly influenced the surface lipid content and whiteness index of microwave‐dried rice for both cultivars. Furthermore, milling duration had significant impacts on the starch damage content and trough viscosity of microwave‐dried rice cultivar XL753 but no significant impact on cultivar Titan. Statistical models predicted HMC of 20% and milling duration of 45 and 42 s for processing microwave‐dried rice cultivars Titan and XL753 respectively, to obtain rice with superior characteristics.ConclusionsHMC and milling duration significantly influenced some physicochemical properties of microwave‐dried rice. We recommend that further studies should be conducted on the cooking, sensory, and storage properties of microwave‐dried rice, to provide information on end‐use and consumer acceptability.Significance and NoveltyThis study provides science‐based information that is vital for optimizing the harvesting and processing conditions of rice dried using the 915 MHz industrial microwave.

Published: April 2022

AbstractDual photoredox‐ and nickel‐catalyzed hydroalkylation of terminal alkynes with 4‐alkyl‐1,4‐dihydropyridines under visible light irradiation to afford Markovnikov‐ or anti‐Markovnikov‐type alkylated alkenes in good‐to‐high yields has been achieved, in which the regioselectivity of the products was effectively controlled by coordination ligands for nickel species. Using [NiCl2(dtbbpy)] as a catalyst led to the formation of Markovnikov‐type products, whereas using NiCl2 ⋅ 6 H2O led to the formation of anti‐Markovnikov‐type products.
Solubility of sodium oxalate in kraft black liquors below 100°C
Authors: Khafhafera Ahmed Naser , Kung Jo‐Wen Jasmine , DeMartini Nikolai 
Published: April 2022

AbstractPrecipitation of sodium salts from kraft black liquor leads to scale formation in the evaporation plants of kraft pulp mills. Sodium oxalate scaling is most prevalent in mills pulping tropical hardwoods such as eucalyptus and acacia, but it has also been found in the scales in high solids lines after the concentrators in mills pulping softwoods. There is very limited solubility data for sodium oxalate in black liquor, especially below 100°C. This study measures the solubility limit in four different black liquors from 14% to 47% dry solids between 50 and 90°C. The newly generated solubility data in black liquors enhance our understanding of sodium oxalate scale formation in low solids effects of the evaporation plant. An example of an application to a kraft pulp mill with sodium oxalate scaling in the seventh effect is given.

Published: April 2022

AbstractLigand‐based 19F NMR screening is a highly effective and well‐established hit‐finding approach. The high sensitivity to protein binding makes it particularly suitable for fragment screening. Different criteria can be considered for generating fluorinated fragment libraries. One common strategy is to assemble a large, diverse, well‐designed and characterized fragment library which is screened in mixtures, generated based on experimental 19F NMR chemical shifts. Here, we introduce a complementary knowledge‐based 19F NMR screening approach, named 19Focused screening, enabling the efficient screening of putative active molecules selected by computational hit finding methodologies, in mixtures assembled and on‐the‐fly deconvoluted based on predicted 19F NMR chemical shifts. In this study, we developed a novel approach, named LEFshift, for 19F NMR chemical shift prediction using rooted topological fluorine torsion fingerprints in combination with a random forest machine learning method. A demonstration of this approach to a real test case is reported.
MONA—A magnetic oriented nodal analysis for electric circuits
Authors: Shashkov Vsevolod , Cortes Garcia Idoia , Egger Herbert 
Published: April 2022

AbstractThe modified nodal analysis (MNA) is probably the most widely used formulation for the modeling and simulation of electric circuits. Its conventional form uses electric node potentials and currents across inductors and voltage sources as unknowns, thus taking an electric viewpoint. In this paper, we propose an alternative magnetic oriented nodal analysis (MONA) for electric circuits, which is based on magnetic node potentials and charges across capacitors and voltage sources as the primary degrees of freedom, thus giving direct access to these quantities. The resulting system has the structure of a generalized gradient system which immediately ensures passivity in the absence of sources. A complete index analysis is presented showing regularity of the magnetic oriented formulation under standard topological conditions on the network interconnection. In comparison to conventional MNA, the differential‐algebraic index of MONA is smaller by one in most cases which facilitates the numerical solution. Some preliminary numerical experiments are presented for illustration of the feasibility and stability of the new approach.
Forward single‐cell sequencing into clinical application: Understanding of cancer microenvironment at single‐cell solution
Authors: Liu Xuanqi , Powell Charles A , Wang Xiangdong 
Published: April 2022

AbstractSingle‐cell RNA sequencing (scRNA‐seq) is considered an important approach to understand the molecular mechanisms of cancer microenvironmental functions and has the potential for clinical and translational discovery and development. The recent concerns on the impact of scRNA‐seq for clinical practice are whether scRNA can be applied as a routine measurement of clinical biochemistry to assist in clinical decision‐making for diagnosis and therapy. Pushing single‐cell sequencing into clinical application is one of the important missions for clinical and translational medicine (CTM), although there still are a large number of challenges to be overcome. The present Editorial as one of serials aims at overviewing the history of scRNA‐seq publications in CTM, sharing the understanding and consideration of the cancer microenvironment at the single‐cell solution and emphasising the objective of translating scRNA‐seq into clinical application. The dynamic characteristics and patterns of single‐cell identity, regulatory networks, and intercellular communication play decisive roles in the properties of the microenvironment, malignancy and migrative capacity of cancer cells, and defensive capacity of immune cells. The microenvironmental single‐cell transcriptomic profiles and cell clusters defined by scRNA‐seq have great value for exploring the molecular mechanisms of diseases and predicting cell sensitivities to therapy and patient prognosis.

AbstractIn this study, for the first time an electrochemiluminescence sensor for ultra‐trace monitoring of lamotrigine is reported. The sensing probe was fabricated using silver prussian blue analogue as a new effective co‐reaction accelerator and carboxylated sulfur‐doped graphitic carbon nitride nanocomposite as a new green luminophore. Also potassium peroxydisulfate was utilized as a strong co‐reactant. The proposed ECL sensor exhibited excellent wide linear range (3.45×10−15 to 2.98×10−8 M), low detection limit (4.89×10−16 M), the relative standard deviation of 1.07 %, outstanding reproducibility and superior long‐term stability. The prominent advantages of the sensor showed that it can be used to determine LMT in clinical samples.

AbstractGraphite is the state‐of‐the‐art anode material for most commercial lithium‐ion batteries. Currently, graphite in the spent batteries is generally directly burned, which caused not only CO2 emission but also a waste of precious carbon resources. In this study, we regenerate graphite in lithium‐ion batteries at the end of life with excellent electrochemical properties using the fast, efficient, and green Flash Joule Heating method (FJH). Through our own developed equipment, under constant pressure and air atmosphere, graphite is rapidly regenerated in 0.1 s without pollutants emission. We perform a detailed analysis of graphite material before and after recovery by multiple means of characterization and find that the regenerated graphite displays electrochemical properties nearly the same as new graphite. FJH provides a large current for defect repair and crystal structure reconstruction in graphite, as well as allowing the SEI coating to be removed during ultra‐fast annealing. The electric field guide the conductive agent and binder pyrolysis products to form conductive sheet graphene and curly graphene covering the graphite surface, making the recycled graphite even better than new commercial graphite in terms of electrical conductivity. Regenerated graphite has excellent multiplier performance and cycle performance (350 mAh g−1 at 1 C with a capacity retention of 99% after 500 cycles). At cost, we get recycled graphite that displays the same performance as new graphite, costing just 77 CNY per ton. This FJH method is not only universal for the regeneration of spent graphite generated by various devices but also enables multiple use‐failure‐regeneration steps of graphite, showing great potential for commercial applications.image

Published: April 2022

AbstractObjectiveSociocultural influences, including an increasing pressure for fashion models to maintain a thin body frame may be crucial in the development of eating disorders. The present study aimed to establish whether fashion models are more likely than non‐models to develop eating disorders.MethodsFemale fashion models were selected by snowball sampling (n = 179, mean age: 25.9 SD = 4.70 years). They were compared with an age adjusted control group (n = 261, mean age: 25.0 SD = 4.97 years). Participants completed an online questionnaire containing the Eating Disorder Inventory.ResultsThe average BMI of the fashion models was in the underweight range (mean BMI = 18.1 SD = 1.68). The BMI of the control group was significantly higher (mean = 22.1 SD = 4.23, p < 0.001). The frequency of simulated anorexia nervosa was 3.9% among the fashion models and 1.1% in the control group (p = 0.057). 14.6% of the models showed subclinical anorexia nervosa symptoms versus 2.7% in the control group (p < 0.001). The ratio of bulimia nervosa and subclinical bulimia nervosa showed no significant difference between the two groups.ConclusionFemale fashion models showed no significant difference from the control group in the frequency of anorexia nervosa and bulimia nervosa but had a significantly higher frequency of the subclinical form of anorexia nervosa.

Published: April 2022

AbstractThis paper constructs a China petroleum market volatility (CPMV) tracker based on Chinese newspapers from March 2018 to July 2021 for the first time. Then, we use the Generalized AutoRegressive Conditional Heteroskedasticity mixed‐data sampling (GARCH‐MIDAS) model to explore the explanatory ability of the CPMV tracker, and the results show that compared with other volatility trackers, the CPMV tracker has a superior ability to explain the volatility of Shanghai crude oil futures (SC). Further, we conduct a more detailed analysis of the CPMV tracker, and find that the CPMV tracker can reflect the information and market sentiment of SC, and needs to be taken into consideration when explaining SC volatility.

AbstractThe price discovery in finance markets has been the focus of many researches. On the basis of 1‐min high‐frequency returns, this paper sets out to examine the dynamics of price discovery between the China Securities Index 300 index and its derivative products: the futures, the index exchange‐traded fund (ETF), and the ETF options. Nonparametric nonlinear method thermal optimal path method is adopted in this study. The empirical evidence shows a clear difference in price discovery ability concerning the three products under investigation, and their rank (sorted by strength) can be presented as options, futures, and ETF. In addition, the leading phenomenon has been verified by the regression method. Furthermore, we find that out‐of‐the‐money options have the strongest price discovery ability among different moneyness option contracts. On this basis, we find that leverage is an important factor affecting the ability of price discovery.

AbstractCD47 expressed on cancer cells enables macrophage immune evasion. Blocking CD47 using anti‐CD47 monoclonal antibodies (mAbs) is a promising strategy. The anti‐CD47 mAb TJC4 has anti‐tumor activity but lacks hematological toxicity. Venetoclax, a B‐cell lymphoma 2 (BCL‐2) inhibitor for B‐cell malignancy, induces phosphatidylserine (PS) extracellular exposure, representing an “eat‐me” signal for macrophages. The present study aimed to explore whether TJC4‐Venetoclax combined therapy exerts synergistic anti‐cancer properties in B‐cell lymphoma. In vitro, flow cytometry and microscopy assessed whether TJC4 monotherapy or combination treatment could promote macrophage‐mediated phagocytosis of tumor cells. Induced PS exposure on the cell membrane was measured using flow cytometry with Annexin V‐FITC staining. In vivo, Venetoclax and TJC4's synergistic anti‐tumor effects were evaluated. B cell lymphoma cell lines express high levels of CD47 and patients with diffuse large B cell lymphoma expressing CD47 have a worse clinical prognosis. TJC4 eliminates tumor cells via macrophage‐mediated phagocytosis. In vitro and in vivo, the TJC4‐Venetoclax combination increased phagocytosis significantly compared with either agent alone, showing synergistic phagocytosis, and displayed synergistic anti‐cancer properties in B‐cell lymphoma. Our results support the TJC4‐Venetoclax combination as a promising therapy, and suppressing BCL‐2 and CD47 simultaneously could represent a novel therapeutic paradigm for B‐cell lymphoma.

Published: April 2022

AbstractIn this study, two distinct nanoparticles: aluminum oxide (Al2O3) and copper (Cu) are chosen as nanomaterials to examine the effects of nonlinear electrically conducting magnetohydrodynamic radiation on the flow of tangential hyperbolic hybrid nanofluid across a nonlinearly stretched sheet with convective boundary conditions. The equations that regulate fluid flow are represented as partial differential equations. These equations are reduced to their equivalent ordinary differential equations, which are solved using the homotopy analysis approach with the help of similarity variables. The effect of essential physical factors on fluid velocity, temperature, skin friction coefficient, and local Nusselt number is investigated and discussed. Results ascertain that the heat transfer rate of Cu/H2O nanofluid becomes high when equated to Cu–Al2O3/H2O nanofluid. Furthermore, the temperature distribution enhances with the rise in solid volume fraction while it diminishes with improved magnetic field for both nanofluid and hybrid nanofluid.

Published: April 2022

AbstractIn this article, we investigate a transient magnetohydrodynamic convective micropolar fluid flow over a semi‐infinite vertical plate embedded in a porous medium in the presence of chemical reaction and thermal diffusion. The dimensionless governing equations are solved by adopting the regular perturbation technique. The impact of various parameters on the velocity, microrotation, temperature, concentration profiles, skin friction, Sherwood number, and Nusselt number over the boundary layer is analyzed using graphs. The fluid velocity and microrotation reduce under the effect of thermal diffusion and chemical reaction. Furthermore, concentration rises due to thermal diffusion (Soret) effect, but concentration falls under the effect of chemical reaction. It is found that the velocity and skin friction fall with enhancing value of magnetic parameter. But Sherwood number increases as the magnetic parameter increase.

IntroductionOwing to the complexity of their blood supply, renal tumors in horseshoe kidneys are sometimes technically challenging to resect through laparoscopic procedures.Case presentationA 75‐year‐old man presented with a 3‐cm lower‐pole mass in the right moiety of the horseshoe kidney. Indocyanine green administration allowed for the identification of the tumor's feeding artery, which was selectively clamped to perform laparoscopic partial nephrectomy. During the procedure, the patient was positioned in the modified supine position (30° semi‐lateral position), which enabled us to approach the branch of the left renal artery. Postoperative pathologic examination of the resected mass confirmed the diagnosis of pT1a clear cell renal cell carcinoma with negative surgical margins.ConclusionOur novel laparoscopic approach with indocyanine green fluorescence in the modified supine position facilitates the identification of and access to the tumor's feeding artery. This technique is advantageous for laparoscopic partial nephrectomy in patients with horseshoe kidney.

AbstractBACKGROUNDThe nutritional and functional potential of eicosapentaenoic acid (EPA)‐ and docosahexaenoic acid (DHA)‐rich oil from Antarctic krill has continued to attract attention worldwide. Therefore, a highly effective approach is essential for extracting Antarctic krill's DHA/EPA‐rich oil and proteins from wet biomass in the same system.RESULTSA cosolvent three‐phase partitioning system (TPPS) was developed to simultaneously extract DHA/EPA‐rich oil and separate proteins (PT) from wet Antarctic krill (Euphausia superba) biomass. The COSMO‐RS was used to screen cosolvents for the extraction of EPA and DHA. The TPPS parameters were optimized by response surface methodology using a central‐composite design, which consisted of 52% (w/w) of cosolvents (t‐butanol:n‐hexane (4:6)), 20% (w/w) of ammonium citrate, 500 rpm of stirring speed, 37 °C of temperature, and 60 min of extraction time. Under the optimized conditions, the extraction efficiency of EPA and DHA was 95.36 ± 0.94% and 93.85 ± 1.31% in the top cosolvents phase, respectively, as well as 86.57 ± 0.98% of proteins in the middle interface. Compared to supercritical CO2 (SCO2) and three‐liquid‐phase salting‐out extraction system (TLPSOES), the recovery rate of krill oil (KO) extracted by TPPS (96.48 ± 1.14%) was much higher than that of the SCO2 (67.8%) and of the TLPSOES method (91%).CONCLUSIONThis study demonstrates that cosolvent TPPSs can extract krill oil from wet krill biomass with higher extraction efficiency, and that the obtained krill oil showed potential antioxidant effects compared to commercial fish oil. Therefore, the cosolvent TPPS could be an alternative in the nutraceutical industry. © 2022 Society of Chemical Industry (SCI).
