Published: November 2023

AbstractIn this work, a number of urethane‐modified polyesteramide (UmPEA) films were developed from mahua and castor oils, which are renewable resources. Mahua oil and diethanolamine were reacted to form mahua fattyamide, which was then reacted with itaconic acid to prepare polyesteramide. In order to make the UmPEA films, different proportions of polyesteramide and castor oil as polyols were reacted with isophoronediisocyanate. The UmPEA films showed excellent chemical resistance against water, acid, alkali, salt, and organic solvents and were found insoluble in common organic solvents. The thermal stability of the UmPEA films was investigated through TGA and DSC analyses, and their Tg values are between 69.1°C and 56.1°C for UmPEA films, which indicated that a higher content of CO enhances the Tg, and it was also found that the films were highly stable up to 230°C. The Ea values [224 kJ mol−1 (Tp1) and 226 kJ mol−1 (Tp2)] indicate that the castor oil enhances the thermal stability of the films due to better cross‐linking density occurring through the high hydroxyl groups of CO as the polyol which also showed better flame retardancy in the synthesized UmPEA films. Our findings demonstrate that the newly developed UmPEA films can be potent coating materials.

AbstractEpoxy‐rich carbon‐based composites are well recognized materials in industries owing to their good mechanical properties and thermal stability. Here, dielectric properties of composites based on bisphenol‐A‐epoxy resin loaded with 5, 6, 10, and 15 wt% of graphite flakes (GF) have been studied. The frequency and temperature dependence of the dielectric permittivity, dielectric loss, and ac conductivity have been examined in temperature (−103 to 97°C) and frequency (20 Hz–200 kHz) range. Influence of the filler surface chemistry have been studied for composites loaded with 5 wt% GF obtained: (i) under wet milling, without or with adding Triton‐100x as a surfactant, or (ii) under dry milling in the presence of KOH. The composite made of epoxy loaded with 5 wt% exfoliated expanded graphite flakes (EEG), was also prepared. The surface treatment with KOH notably increased dielectric constant of the composite, keeping low dielectric loss, while treatment with Triton‐100x significantly increased tanδ. The composite loaded with exfoliated expanded graphite shows higher ac conductivity than those obtained with flaky graphite, GF. Possibility to change dielectric properties of the composites without changing the loading content can be used as an approach in tailoring one with desired dielectric properties.

Abstract

Historically, considerations of the carbon budget of bivalve shellfish have disproportionately focused on the cycling of carbon in shell alone, overlooking respiratory release and the potential role of bivalve shellfish habitats in the stabilization of sediment, and therefore of carbon.
Data on carbon cycling are key to providing essential evidence to inform evaluation of management strategies and the business case for restoration of European flat oyster (Ostrea edulis) habitats. The purpose of this study was to examine the flat oyster carbon budget at the scale of the individual and to set out a framework to enable future comparisons of carbon budgets between ecosystems.
Through the combination of previously established work with measurements of calcification and respiration both in situ and ex situ, a carbon budget at the scale of a single oyster was determined.
In consideration of the flat oyster carbon budget, the inclusion of the deposition of sedimentary carbon, as well as carbon stored in shell, balanced with the release of carbon through respiration and calcification suggests that these habitats are unlikely to be significant carbon sinks in the context of global climate change mitigation. However, the recovery of flat oyster beds is likely to facilitate the accretion of substantial carbon stocks that are nevertheless important in conservation management.

AbstractBackgroundThere is limited knowledge regarding the impact of perioperative critical care on frequency of neurological imaging findings following esophageal atresia (EA) repair.MethodsThis is a retrospective study of infants (n = 70) following EA repair at a single institution (2009–2020). Sex, gestational age at birth, type of surgical repair, underlying disease severity, and frequency of neurologic imaging findings were obtained. We quantified the length of postoperative pain/sedation treatment and anesthesia exposure in the first year of life. Data were presented as numerical sums and percentages, while associations were measured using Spearman's Rho.ResultsVertebral/spinal cord imaging was performed in all infants revealing abnormalities in 44% (31/70). Cranial/brain imaging findings were identified in 67% (22/33) of infants in the context of clinically indicated imaging (47%; 33/70). Long‐gap EA patients (n = 16) received 10 times longer postoperative pain/sedation treatment and twice the anesthesia exposure compared with short‐gap EA patients (n = 54). The frequency of neurologic imaging findings did not correlate with underlying disease severity scores, length of pain/sedation treatment, or cumulative anesthesia exposure. Lack of associations between clinical measures and imaging findings should be interpreted with caution given possible underestimation of cranial/brain findings.ConclusionsWe propose that all infants with EA undergo brain imaging in addition to routine spinal imaging given the high burden of abnormal brain/cranial findings in our cohort. Quantification of pain/sedation and anesthesia exposure in long‐gap EA patients could be used as indirect markers in future studies assessing the risk of neurological sequelae as evidenced by early abnormalities on brain imaging.

AbstractObjectiveTo investigate the predictive value of the systemic immune inflammation (SII) index on the occurrence of stroke‐associated pneumonia (SAP) in patients with acute stroke.MethodsData of patients with or without a previous history of pulmonary who visited the First Affiliated Hospital of Kunming Medical University within 24 h of the onset of stroke were collected between January 2017 and December 2019. Patient's demographic data, stroke type, past medical history, National Institutes of Health Stroke Scale score, Glasgow Coma score, and laboratory tests were collected. Logistic regression models and receiver‐operating characteristic (ROC) curves were used to investigate the predictive value of SII for the development of SAP in patients with stroke.ResultsWe included 395 patients with acute stroke, with a mean age of 63.89 ± 13.42 years, of whom 340 (86.1%) had ischemic stroke, and 55 (13.9%) had hemorrhagic stroke. Out of 395, 113 (28.6%) had SAP and 282 (71.4%) did not, and the SII level in the SAP group was higher than that of the non‐SAP group (p < .05). Logistic regression analysis of patients with stroke showed that higher SII was a risk factor for SAP in patients with stroke (per 100 units, HR = 1.081, 95% CI: 1.035–1.130, p < .001), and tertile grouping of SII showed that the risk of SAP was 5.059 times higher in the SIIQ3 group than in the SIIQ1 group (95% CI: 2.061–12.418, p < .001). ROC curve analysis indicated that the SII index had predictive value for the occurrence of SAP in patients with stroke, with an area under the curve of 0.752 (95% CI: 0.698–0.806). When the cutoff value was 861.01, the SII predicted SAP in patients with stroke with a sensitivity of 61.9% and a specificity of 76.2%.ConclusionHigher SII is an independent risk factor for the development of SAP in patients with stroke and has some predictive value for the development of SAP.
Saving the environment with indigenous directors: Evidence from Africa

Published: November 2023

AbstractWe build on and extend the literature on corporate governance and sustainability by examining whether indigenous directors (IDs, hereinafter) shape corporate environmental performance (CEP, hereinafter). Drawing insights from image motivation, resource dependence, and critical mass theories, we develop models that link IDs with CEP. Analyzing 1,372 firm‐year observations extracted from firms listed on the Johannesburg Securities Exchange (JSE, hereinafter), for the period spanning from 2015 to 2021, we provide robust evidence that IDs are positively associated with a firm's environmental performance and the association is driven primarily by non‐executive and female IDs. In additional analyses, we demonstrate that a token appointment of IDs to a firm's board would not have an impact on CEP, while the appointment of a “critical mass” of IDs promotes CEP. We also find that a higher percentage of IDs on a firm's board increases corporate financial performance (CFP, hereinafter) and reinforces the positive impact of CEP on CFP. Our findings suggest that appointing a higher proportion of IDs to a firm's board promotes both the financial as well as the environmental performance of the firm. Thus, companies could exploit the virtues of especially non‐executive and female IDs to promote corporate environmental sustainability.

Published: November 2023

AbstractEnvironmental challenges have led to a shift toward more sustainable consumption and production patterns. Understanding the factors that influence consumers' choices toward green products is crucial for achieving sustainable development. This study investigates the adoption process of a low‐involvement eco‐innovation, examining the influence of the level of green consumerism, the perception of its technological and symbolic dimensions, social pressure, and social conspicuousness. A sample of 268 observations was examined using the PLS‐SEM methodology. The results highlightthe indirect effect of the level of green consumption on low‐involvement eco‐innovation adoption through the perception of its technological and symbolic dimensions, as well as social pressure and social conspicuousness. These findings have important practical implications for the design of marketing strategies aimed at promoting low‐involvement eco‐innovations. By emphasizing the social benefits and the influence of others on adopting green behaviors, marketers can effectively target consumers and facilitate the transition toward more sustainable consumption patterns.

AbstractThe application of small organic molecules for sodium‐ion batteries is generally plagued by their high solubility, poor conductivity, and sluggish redox dynamics in organic electrolyte, thus developing efficient strategies to restrain solubilization while obtaining fast charge transfer becomes a challenge. Herein, a rational hybridization strategy through hydrogen bond between organic molecule and inorganic substrate has been proposed, employing the terminal –C═O of trisodium 1, 2, 4‐benzenetricarboxylate (TBC) molecule and –OH groups of inorganic Ti3C2Tx MXene, respectively. In general, such a design evidently mitigates the aggregation of both TBC molecules and Ti3C2Tx MXene. Furthermore, the robust hydrogen bonding significantly mitigates the dissolution of TBC and guarantees the robust coupling between them, thus contributing to the integrity of electrode and modifying the electrochemical sodium storage in both half and full cells. Moreover, the systematic kinetic analysis and mechanism detection reveal improved charge transportation and robust two‐electron electrochemical reversibility of the hybrid TBC/Ti3C2Tx. Taken together, this work demonstrates a potential novel strategy toward stable and practical organic battery chemistries through hydrogen bonding with inorganic compounds.
A novel fault detection scheme for a nonlinear dynamic process based on generalized non‐negative matrix projection‐maximum mean discrepancy: Application on the DAMADICS benchmark process

Published: November 2023

AbstractIn order to address the issue of minor fault detection in nonlinear dynamic processes, this paper proposes a fault detection method based on generalized non‐negative matrix projection‐maximum mean discrepancy (GNMP‐MMD). Firstly, the GNMP is employed to acquire the residual scores of the samples. Subsequently, a sliding window approach is integrated with MMD for real‐time monitoring of sample status within the residual subspace. In this study, GNMP is utilized to mitigate the impact of non‐Gaussianity in data distribution, while MMD serves to alleviate autocorrelation among samples. A numerical case and experimental data collected from the DAMADICS process are utilized to simulate and validate the proposed method. Compared to traditional principal component analysis (PCA), dynamic principal component analysis (DPCA), dynamic kernel principal component analysis (DKPCA), non‐negative matrix factorization (NMF), GNMP, and MMD, the experiment results clearly illustrate the feasibility of the proposed method.

Published: November 2023

AbstractBackgroundOmentin‐1 is a novel adipokine and is associated with chronic inflammation and cardiovascular diseases. However, it remains unclear whether omentin‐1 levels are associated with diagnostic significance in elderly patients with heart failure with preserved ejection fraction (HFpEF). This study aimed to investigate the correlation between omentin‐1 and HFpEF in Chinese elderly patients.HypothesisOmentin‐1 may be invovled in HFpEF and there may be a difference of omentin‐1 levels between HFpEF and control.Methods217 subjects were selected, including 115 patients with HFpEF and 102 control subjects. Enzyme‐linked immuno sorbent assay (ELISA) was used to detect plasma levels of omentin‐1, tumor necrosis factor‐α (TNF‐α) and interleukin‐6 (IL‐6). The receiver operating characteristics (ROC) curve was used to examine the diagnostic performance of omentin‐1 in HFpEF.ResultsThe levels of omentin‐1 decreased significantly in the HFpEF group (14.02 ± 8.35 vs. 19.74 ± 8.45 ng/mL, p < .001), while NT‐proBNP, IL‐6, and TNF‐α levels were significantly increased in the HFpEF group compared with the control group. Spearman correlation analysis showed that omentin‐1 levels were negatively correlated with E/e' (r = −.340, p < .001). The multivariate logistic regression analysis indicated that omentin‐1 was an independent protective factor for HFpEF (odd ratio = 0.948, 95% confidence interval [CI] 0.905–0.993, p = .025). Omentin‐1 levels were negatively correlated with NT‐proBNP (r = −.273, p < .001) and TNF‐α (r = −.221, p = .001). Diagnostic efficiency by ROC curve analysis in the patients with HFpEF showed that the area under the curve (AUC) for omentin‐1 was equivalent to NT‐proBNP (AUC: 0.734, 95%CI 0.667–0.802; AUC: 0.800, 95%CI 0.738–0.861). Subgroup analysis showed that in the patients between the age of 70 and 80, the predictive capability of omentin‐1 was stronger than NT‐proBNP (AUC: 0.809, 95%CI 0.680–0.937; AUC: 0.674, 95%CI 0.514–0.833).ConclusionsOmentin‐1 levels which were associated with inflammation, were decreased in the HFpEF patients. It could be regarded as a valuable biomarker for the occurrence and development of HFpEF in elderly patients.

Published: November 2023

AbstractIn this study, we have developed a novel approach for synergistic tumor treatment by utilizing degradable dendritic mesoporous silica nanoparticles loaded with doxorubicin and curcumin (Cur). These nanoparticles are equipped with polydopamine (PDA) for photothermal therapy and hyaluronic acid (HA) as a targeting ligand. The incorporation of PDA not only ensures the controlled release of therapeutic agents but also confers pH and photothermal responsiveness to the nanocarriers. Cur, a natural compound, serves as an antitumor sensitizer, elevating intracellular ROS levels to promote apoptosis. In addition, the excellent biocompatibility and targeting property of nanocarriers were enhanced by the HA‐modification, improving the effective accumulation in tumor cells. Comprehensive research including MTT assay, live/dead staining and ROS generation proved that the excellent antitumor capability of dual‐drug loaded nanocarriers was a result of chemo‐photothermal synergistic therapy and Cur‐induced cellular amplified ROS generation. The cellular uptake assays further demonstrated the efficiency of HA‐mediated intracellular accumulation, accelerated uptake driven by photothermal‐induced and a precise internalization pathway of nanocarriers. Furthermore, the results of in vivo biocompatibility revealed no significant blood and organ toxicity associated to the prepared nanocarriers. Our findings underscore the substantial potential of the proposed dual‐drug loaded nanocarriers for chemo‐photothermal synergistic therapy, offering a safe and promising strategy for effective tumor treatment.

AbstractBackgroundSignificant miss‐expressed gene indicators contributing to cisplatin resistance in ovarian cancer have not been completely understood. It seems that several regulatory genes and signaling pathways are associated with the emergence of the chemo‐resistant phenotype.AimsHere, a meta‐analysis approach was adopted to assess deregulated genes involved in relapse after the first line of chemotherapy (cisplatin).Methods and ResultsTo do so, six ovarian cancer libraries were gathered from GEO repository. Batch effect removal and quality assessment, and boxplots and PCA were performed using SVA and ggplot2 packages in R, respectively. Cisplatin‐resistant and ‐sensitive ovarian cancer groups were compared with find genes with significant expression changes using linear regression models in the LIMMA R package. The significance threshold for DEGs was taken as adj p‐value < .05 and − 1 > logFC > 1. A total of 261 genes were identified to have significant differential expression levels in the cisplatin‐resistant versus cisplatin‐sensitive group. Among the 10 top up‐regulated and down‐regulated genes, PITX2, SNCA, and EPHA7 (up), as well as TMEM98 (down) are indirect upstream regulators of PI3K/AKT signaling pathway, contributing greatly to the development of chemo‐resistance in cancer via promoting cell proliferation, survival, and cell cycle progression as well as inhibiting apoptosis. Moreover, a comprehensive assessment of DEGs revealed the dysregulation of not only membrane ion channels KCa1.1, Kv4, and CACNB4, affecting cell excitability, proliferation, and apoptosis but also cell adhesion proteins COL4A6, EPHA3, and CD9, affecting the attachment of normal cells to ECM and apoptosis, introducing good options to reverse cisplatin resistance.ConclusionOur results predict and suggest that upstream regulators of PI3K/AKT signaling pathway, ion channels, and cell adhesion proteins play important roles in cisplatin resistance development in ovarian cancer.
CIE color coordinates for the design of luminescent glass materials

Published: November 2023

AbstractNew photoluminescent materials have numerous possibilities in many different areas from technological applications to contemporary glass art and design, encouraging the development of new forms and products. Glass luminescent materials, known for their exceptional durability and recyclability, position glass as an ideal solution for fostering a more sustainable future. In recent years, white luminescence in glass and ceramics has been the subject of several investigations about its possible application in white light‐emitting diodes (WLED). Color coordinates and CIE chromaticity diagrams serve as valuable tools to represent and define the range of luminescent colors achievable in a particular composition. These aid in understanding wheter a composition can be used to produce white luminescence or various other colors. In this study, a soda‐lime silicate glass composition was doped with a mixture of different lanthanide oxides to increase the luminescence color palette. The same glass sample can also present different colors by changing the excitation light, allowing higher tunability of luminescent colors. It was effectively demonstrated the extensive spectrum of colors produced, which was represented through luminescence color coordinates for all synthesized glasses. Moreover, the possibility of detecting if an excited state process is occurring was studied by calculating the lanthanides factors and comparing them with those used in the glass synthesis. Nevertheless, it is shown that the energy transfer process has to be significant to influence the color coordinates and the calculation of the factors.
