Authors: Li Kenan , Cheng Xiaoquan , Zhang Xianglin , Huang Wenjun 
Published: February 2024

AbstractCompressive performances of composite structures can be significantly decreased due to the lightning strike damage, so the structures with lightning frighten must be considered lightning protection design. In this study, compressive experiments after lightning strikes were conducted on non‐protected, 12‐layer interlaminar carbon nanotube film (CNF) protected, and traditional surface silver coating (TSSC)‐protected composite laminates. A numerical analysis procedure was established, incorporating a lightning strike ablation damage simulation (LSADS) module and compressive residual strength calculation (CRSC) module. The procedure's effectiveness was verified by the experiment results. Based on this procedure, the compressive performances and the possible failure mechanism of laminates after lightning strikes were analyzed. The results show that the laminates with TSSC protection and 12‐layer interlaminar CNF protection can increase compressive residual strength compared with non‐protected laminates. The predominant compressive damages of the laminates after lightning strikes are fiber‐matrix shear damage and fiber fracture damage. Optimized one‐layer interlaminar CNF protection with a thickness of 0.36 mm can increase the laminate compressive strength but decrease the structural weight. This study offers a reference and basis for the lightning strike protection design of composite structures.Highlights

AbstractIntroductionCitri Sarcodactylis Fructus (CSF), a common fruit and traditional Chinese medicine (TCM), has been hindered in its further development and research owing to the lack of comprehensive and specific quality evaluation standards.ObjectiveThis study aimed to establish clear TCM quality standards related to the therapeutic mechanisms of CSF and to provide a basis for subsequent research and development.MethodsUltra‐high performance liquid chromatography coupled with hybrid quadrupole‐orbitrap high‐resolution mass spectrometry (UPLC‐Q‐orbitrap HRMS) technology was used to comprehensively identify CSF components and explore their absorbance levels in rat serum. Network pharmacology research methods were employed to investigate the potential mechanisms of action of the identified components in the treatment of major clinical diseases. Subsequently, a combination of HPLC chromatographic fingerprinting for qualitative analysis and multi‐index content determination was used to evaluate the detectability of the identified quality markers (Q‐markers).ResultsTwenty‐six prototype components were tentatively characterized in rat serum. Network pharmacology analysis showed six effective components, namely 7‐hydroxycoumarin, isoscopoletin, diosmin, hesperidin, 5,7‐dimethoxycoumarin, and bergapten, which played important roles in the treatment of chronic gastritis, functional dyspepsia, peptic ulcer, and depression and were preliminarily identified as Q‐markers. The results of content determination in 15 batches of CSF indicated significant differences in the content of medicinal materials from different origins. However, compared with the preliminarily determined Q‐markers, all six components could be measured and were determined as Q‐markers of CSF.ConclusionThe chemical Q‐markers obtained in this study could be used for effective quality control of CSF.
Activation energy and molecular weight dependence of cooperative tracer chains diffusion in highly entangled polymer melts
Authors: Ngai K. L. 
Published: February 2024

AbstractThe generalized Langevin equation for cooperative dynamics of Guenza predicts the dynamics of chains in entangled polymers is cooperative with anomalous properties, and at variance with the tube‐reptation model. The center‐of‐mass mean‐square displacements at shorter times are subdiffusive with with β < 1, contradicting the common assumption of reptation within the tube. At some longer time the subdiffusive dynamics exhibits the crossover to free diffusion with . Moreover the subdiffusive dynamics is heterogeneous, non‐Gaussian, and cooperative. These predictions have been confirmed by using neutron spin echo spectroscopy in entangled polyethylene melts [M. Zamponi, et al. J. Phys. Chem. B 2008, 112, 16220], and in tracer diffusion of short polyethylene chains in a highly entangled polyethylene melt [M. Zamponi et al. Phys. Rev. Lett. 2021, 126, 187801]. The latter was confirmed in poly(ethylene oxide) tracer diffusion in highly entangled poly(ethylene oxide) melt [M. Kruteva et al. Macromolecules 2021, 54, 11384]. Notwithstanding, there are other important data sets obtained in the NSE experiments but were left unexplained. One set consists of the activation energies of the Arrhenius temperature dependence of D for each tracer. Another is the molecular weight dependence of D of the tracers determined at the same temperature. In this article the predictions of the Coupling Model are applied to these two sets of data. Good quantitative agreements of the CM predictions with experimental data provide additional support to the cooperativity dynamics of entangled polymers as concluded by others. Additionally, all the properties of cooperative diffusion of entangled polymer chains are shown to be isomorphic to those found in cooperative diffusions in totally different systems. Diffusion in all are governed by interaction between the diffusing units, and from which the universal properties originate.

Published: February 2024

AbstractObjectiveHematopoietic stem cell transplantation (HSCT) is considered an integral part of therapy in many hematological and non‐hematological malignancies. The procedure can be highly stressful for patients. The primary objective of this study was to compare stress assessments in HSCT patients, depending on their stress coping style (CS) and type of treatment (autologous vs. allogeneic HSCT).MethodsA short longitudinal study was conducted between May 2021 and June 2023 among patients with hematological cancers undergoing HSCT. The study involved four time points: the day of admission to hospital – T1, the day before HSCT – T2, 6 days after HSCT – T3, and the day of discharge – T4. Participants completed the Coping Inventory for Stressful Situations (CISS) on T1, and the Distress Thermometer (DT) on T1‐T4. Descriptive statistics and a repeated measures ANOVA were conducted.ResultsA total of 128 participants completed the study: 54.2% female, mean age 48.7 years. They were divided into: (1) five groups based on their CS: task‐oriented, emotion‐oriented, avoidance‐oriented, mix‐oriented, differential‐oriented; (2) two groups based on treatment type. The analyses showed significant differences in stress between the CS study groups (p = 0.001). The emotion‐oriented group had the highest stress levels during the hospitalization period. There was also a significant time effect (p < 0.001): stress levels increased during the hospitalization period, peaking 6 days after HSCT, and decreased at discharge.ConclusionsStress levels depend on coping styles and time points during the hospitalization period, which should be taken into account in planning psychological interventions for HSCT patients.

AbstractThis work presents a comparison between electrochemical (Echem), plasma glow, and arc discharge polymerizations of pyrrole doped with iodine to correlate the energy of synthesis, chemical structure, and electrical conductivity of the polymers. Plasma glow discharges were used in the gas phase, electrochemistry in liquid, and arc discharges in a hybrid gas–liquid combination. Polypyrroles had structure and conductivity that varied with the synthesis parameters; Echem produced polymers with high carbonization and without the C≡N triple bonds resulting from the other syntheses. Conductivity divided the polymers in two: those synthesized in liquid were in the 0.01–1.0 S/m range, and those synthesized in gas were in the 10–9–10–7 S/m range, with differences of up to eight orders of magnitude due to the dopants and electrolytes.

AbstractBackgroundCan physiotherapy with a positive expiratory pressure (PEP) mask improve peripheral ventilation inhomogeneity, a typical feature of children with cystic fibrosis (cwCF)? To answer this question, we used the nitrogen multiple‐breath washout (N2MBW) test to measure diffusion‐convection‐dependent inhomogeneity arising within the intracinar compartment (Sacin*VT).MethodsFor this randomized, sham‐controlled crossover trial, two N2MBW tests were performed near the hospital discharge date: one before and the other after PEP mask therapy (1 min of breathing through a flow‐dependent PEP device attached to a face mask, followed by three huffs and one cough repeated 10 times) by either a standard (10–15 cmH20) or a sham (<5 cmH20) procedure on two consecutive mornings. Deception entailed misinforming the subjects about the nature of the study; also the N2MBW operators were blinded to treatment allocation. Study outcomes were assessed with mixed‐effect models.ResultsThe study sample was 19 cwCF (ten girls), aged 11.4 (2.7) years. The adjusted Sacin*VT mean difference between the standard and the sham procedure was −0.015 (90% confidence interval [CI]: −∞ to 0.025) L−1. There was no statistically significant difference in Scond*VT and lung clearance index between the two procedures: −0.005 (95% CI: −0.019 to 0.01) L−1 and 0.49 (95% CI: −0.05 to 1.03) turnovers, respectively.ConclusionOur findings do not support evidence for an immediate effect of PEP mask physiotherapy on Sacin*VT with pressure range 10–15 cmH20. Measurement with the N2MBW and the crossover design were found to be time‐consuming and unsuitable for a short‐term study of airway clearance techniques.

AbstractBackgroundAndrogen deprivation therapy (ADT) is an effective treatment for advanced prostate cancer (PCa). Multiple studies have highlighted serious consequences this therapy poses to mental health, particularly depression. We aimed to review the incidence and association between ADT in men with PCa and the risk of depression.MethodsWe systematically searched multiple databases, including MEDLINE, Scopus till August 2023 for studies that compared ADT versus control for treating PCa reporting depression as outcome. Meta‐analysis was performed using random‐effects models and results presented as odds ratios (ORs) with 95% confidence interval (CI). Quality assessment of the included studies was conducted using Joanna Briggs Institute critical appraisal checklists.ResultsA total of 38 studies (17 retrospective studies, 16 prospective studies, two cross‐sectional studies and two randomized trials) with 360,650 subjects met the inclusion criteria and were included in this meta‐analysis. The estimated pooled incidence of depression among ADT patients is 209.5 (95% CI = 122.3; 312.2) per 1000 patients. There is statistically significant relationship between ADT treatment and depression (OR = 1.46, 95% CI = 1.28, 1.67; p = 0, I2 = 86.4%). The results remained consistent across various subgroups. No risk of publication bias was detected by funnel plot and Eggers's test (p > 0.05).ConclusionThere is a higher risk of depression for men receiving ADT. Further studies evaluating optimal treatments for depression in men on ADT are warranted
Remotely sensed land‐cover change and floodplain disturbance following upstream‐migrating river avulsions in tropical rainforests
Authors: Henson Riley T. , Edmonds Douglas A. , Lazarus Eli D. 
Published: February 2024

AbstractThe displacement of a river to a new position within its adjacent floodplain is called avulsion, and here we examine how a newly recognized style, called retrogradational avulsion, affects the surrounding floodplain in tropical rainforests using remote sensing. Retrogradational avulsions begin with a channel blockage that causes self‐propagating upstream dechannelization and flooding. While this flooding results in vegetation die‐off and floodplain sedimentation, few quantitative measurements of disturbance by retrogradational avulsions exist. Here, we first focus on land‐cover change following a single retrogradational avulsion in Papua New Guinea from 2012 to 2021. During the avulsion, the river dechannelized 892 m upstream, and the parent channel width doubled. Using maximum likelihood image classification, we observed healthy vegetation fluctuated around 4.3 km2, vegetation regrowth peaked in 2017 at 3.2 km2, dead vegetation peaked in 2013 at 2.1 km2, and visible extent of deposited sediment was greatest in 2015 at 0.44 km2. We also examined 19 other retrogradational avulsions in Papua New Guinea and South America using NDVI. The area of floodplain disturbance (i.e., vegetation die‐off and possible sedimentation) for each avulsion ranged from <1 to >13 km2 and scaled with the dechannelization area. Comparing our plan‐view disturbance results with FABDEM digital‐elevation data and ICESat‐2 surface elevation measurements, we hypothesize floodplain disturbance extent is a function of topographic relief. Our results also suggest that retrogradational avulsions, on average, perturb larger areas of forest compared to blowdowns, suggesting this might be an important disturbance regime that influences gap‐filling regeneration in tropical rainforests.

Published: February 2024

AbstractRecently, the globe has been facing several challenges, and environmental deterioration has become more prominent. Therefore, to deal with such environmental issues, the globe has tried to introduce several green initiatives via the Kyoto Protocol, the Paris Agreement, and the Sustainable Development Goals, but the problem remains intact. However, practitioners have no more choice but to exclude emerging economies from this race. For instance, to understand the response of emerging economies toward a sustainable environment, this study considers BRICS (Brazil, Russia, India, China and South Africa) economies. Similarly, the current empirical study utilizes innovative environmental determinants such as real income, urbanization, entrepreneurial activities, per capita renewable energy, financial innovation and environmental policy for selected regions from 2000 to 2021. However, the findings of the advanced estimators' series show the significant contribution of per capita green energy consumption, environmental policy and entrepreneurial activities toward environmental sustainability. In contrast, income, financial inclusion and urbanization contribute to environmental damage. Because of green energy supportive behavior, this study makes an additional step to investigate the mediating effect on financial inclusion, environmental policy and entrepreneurship. However, the mediating effect only supports environmental policy and entrepreneurship activities to reduce environmental pressure. From the policy perspective, the specified economies should allocate their financial resources to clean & green projects to attain the desired level of sustainability.

AbstractThe traditional lateral flow immunoassay (LFIA) with a single signal output mode may encounter challenges such as low sensitivity, poor detection range, and susceptibility to external interferences. These limitations hinder its ability to meet the growing demand for advanced LFIA. To address these issues, the rational development of multifunctional labels for multimodal LFIA emerges as a promising strategy. Herein, this study reports a multimodal LFIA using “four‐in‐one” multifunctional dandelion‐like gold@platinum nanoparticles (MDGP). The inherent properties of MDGP, such as the broad absorption spectrum, porous dandelion‐like nanostructure, and bimetallic composition with gold and platinum, endow them with capacities in dual spectral‐overlapped fluorescence quenching, optical readout, catalytic activity, and photothermal effect. Benefiting from their multifunctional properties, the MDGP‐LFIA enables multimodal outputs including fluorescent, colorimetric, and photothermal signals. This multimodal MDGP‐LFIA allows for the detection of acetamiprid at a range of 0.01–50 ng mL−1, with the lowest qualitative and quantitative detection results of 0.5 and 0.008 ng mL−1, respectively, significantly better than the traditional gold nanoparticles‐based LFIA. The diversity, complementarity, and synergistic effect of integrated output signals in this multimodal MDGP‐LFIA improve the flexibility, practicability, and accuracy of detection, holding great promise as a point‐of‐care testing platform in versatile application scenarios.

Published: February 2024

AbstractCell sheet technology has emerged as a novel scaffold‐free approach for cell‐based therapies in regenerative medicine. Techniques for harvesting cell sheets are essential to preserve the integrity of living cell sheets. This review provides an overview of fundamental technologies to fabricate cell sheets and recent advances in cell sheet‐based tissue engineering. In addition to the commonly used temperature‐responsive systems, we introduce alternative approaches, such as ROS‐induced, magnetic‐controlled, and light‐induced cell sheet technologies. Moreover, we discuss the modification of the cell sheet to improve its function, including stacking, genetic modification, and vascularization. With the significant advances in cell sheet technology, cell sheets have been widely applied in various tissues and organs, including but not limited to the lung, cornea, cartilage, periodontium, heart, and liver. This review further describes both the preclinical and clinical applications of cell sheets. We believe that the progress in cell sheet technology would further propel its biomedical applications.

Published: February 2024

AbstractDisposal of the concentrate of the reverse osmosis process (ROC) is a challenge arising from implementing reverse osmosis‐based treatments for water supply. Environmentally friendly management options are related to technological changes tending to dismiss the environmental damage and offer reuse of the concentrate. In this work, we study the efficiency of a widely available material (laterite) for arsenic removal from raw ROC belonging to a treatment water supply plant. Assays of laterite were performed under batch conditions, by suspending it in raw ROC solutions enriched with As(V). Results indicated that arsenic adsorption was complete after 6 h of contact. Kinetic adsorption followed a law of the pseudo‐second‐order, where the rate was 96 g mg−1 h−1. The maximum adsorption capacity and equilibrium constant, which were determined by fitting equilibrium data to the Langmuir model adequately, were 154 µg g−1 and 0.9 L µg−1, respectively. The interaction between arsenic and laterite has a physical nature. From the raw ROC with an arsenic concentration near 150 µg L−1, a reduction of 62% was determined. The final concentrations of the treated solutions resulted in adequate for several reuse purposes in agricultural activities, such as crop irrigation and supplementation of animal drinking water.

Published: February 2024

AbstractBackgroundForages are widely used in horse diets. Different in vitro techniques are being tried to determine the fermentation levels of forages in the horse digestive tract.ObjectivesThis study aimed to evaluate the digestion levels of four dry forages commonly used in horse nutrition: alfalfa herbage, meadow hay, wheat straw, and Italian ryegrass. In vitro total digestion (TDT), in vitro Sunvold–large intestine digestion (SDT) and in vitro Menke–large intestine digestion (MDT) techniques were compared.MethodsThe study determined in vitro true dry matter digestion (T‐DMD), in vitro true organic matter digestion (T‐OMD) and in vitro true neutral detergent fibre digestion (T‐NDFD). Additionally, concentrations of straight short‐chain fatty acids (SCFAs; acetic acid – AA, propionic acid , butyric acid, and valeric acid ) and branched short‐chain fatty acids (BSCFA) were assessed.ResultsThe highest in vitro T‐DMD, T‐OMD and T‐NDFD values were determined by the in vitro TDT for the four forages (p < 0.05). In vitro T‐DMD and T‐OMD values of alfalfa herbage were higher than those of Italian ryegrass, meadow hay and wheat straw in the in vitro TDT (p < 0.001). In addition, in vitro T‐DMD and T‐OMD values of alfalfa herbage in the in vitro SDT were higher than those of meadow hay and wheat straw (p < 0.001). In the in vitro TDT, the molarity of AA, total SCFA and BSCFA in the digestion fluid of alfalfa herbage was higher than those of other forages (p < 0.05).ConclusionThe in vitro total enzymatic + fermentative digestion technique for horse forages revealed higher values than the in vitro fermentative digestion techniques. In general, the higher the non‐structural carbohydrate and crude protein contents in the forage, the higher the results of the in vitro TDT compared to the other techniques.
