Published: October 2024

AbstractRecycled polypropylene (rPP)/crystalline cellulose (rPP/CC) composites are promising alternatives for reducing the detrimental environmental consequences of virgin PP. However, the incompatibility of the rPP/CC composites hinders their widespread application. In this study, PP functionalized with maleinized hyperbranched polyol polyester (PP‐g‐MHBP) was used as a compatibilizing and plasticizing agent for the rPP/CC composites. Furthermore, the effect of PP‐g‐MHBP content on the rheological, thermal, morphological, and mechanical properties of the rPP/CC composites was evaluated. The composites were prepared at a mixing speed of 50 rpm for 7 min and the PP‐g‐MHBP content was varied between 0 and 20 wt%. The torque stabilization time was less than 1 min. The activation energy of flow () decreased with increasing PP‐g‐MHBP content, with its values ranging from 0.78 × 102 to 1.42 × 102 kcal.mol−1. The flow index () followed the opposite trend with values ranging from 0.55 ± 0.0030 to 0.85 ± 0.0010. PP‐g‐MHBP enhanced the processability, thermal stability and conductivity. The crystallinity, interactions between rPP and CC, and tensile modulus of the rPP/CC composites were also enhanced. Furthermore, it reduced the agglomeration of CC particles.Highlights
The torque stabilization was lowest for all composites.
The composites displayed low activation energy of flow.
Recycled polypropylene and crystalline cellulose exhibited good interaction.
The plasticizing effect was higher than that of compatibilization.
The thermal stability and mechanical properties of the composites improved.

AbstractWith the emergence of two‐dimensional (2D) materials analogous to graphene, transition metal carbides and carbonitrides with unique desirable characteristics known as MXenes have turned out to be a hot research topic. Recent studies increasingly focus on the structure–property relationships of MXenes and their hybrid formations with other materials. The exfoliation and delamination of MXenes using various agents is gaining attention, while their application in functional composites presents another exciting research direction. However, the exfoliation of multi‐layered MXene into few‐layered nanosheets using bio‐based agents remains underexplored. In this study, tannic acid (TA) is employed as a bio‐exfoliating agent to delaminate Ti3C2Tx MXene, while optimizing the ratio of TA to achieve efficient exfoliation and dye adsorption. The MXene/TA composites demonstrated a maximum adsorption capacity of 187.264 mg/g and a removal efficiency of 93.69% for methylene blue (MB) in water, in accordance with the Langmuir isotherm model. Furthermore, MB adsorption caused MXene to coagulate into floccules, enabling easy removal via filtration. The study highlights the trifold role of tannic acid in MXene as a delaminating, antimicrobial, and adsorption‐enhancing agent, creating a multifunctional MXene‐tannic acid system. It introduces a new class of hybrid materials with effective applications in water purification. Additionally, incorporating this hybrid material into polymers can fine‐tune their properties, leveraging the synergistic effects of the trio to develop high‐performance smart polymer composites for diverse applications.Highlights

AbstractThis study advances the creation of biocomposite materials and serves to reduce and utilize agricultural waste such as pineapple leaf fibers (PALF). In this study, PALF‐reinforced natural rubber (NR) composites with included multi‐walled carbon nanotubes (MWCNT) were analyzed and characterized at various fiber loadings. The PALF content was ranged from 0, 10, 20 to 30 parts per hundred rubber (phr) while the MWCNT content was maintained at 10 phr. A two‐roll mill mixing process followed by molding was employed to fabricate the NR composites. Based on the curing behavior, tribological properties, and morphological analysis, it was confirmed that the hybrid reinforcement of the MWCNT and PALF improved the curing behavior, wear resistance, and morphology of the composites. The wear and friction properties of the composites namely coefficient of friction (COF), frictional force and specific wear rate (SWR) are significantly influenced by the applied loads. The COF of NR/30PALF and NR/30PALF/MWCNT composites is reduced to 0.80 and 0.72 respectively under 15 N of load. Physical properties namely the cross‐link density and swelling behavior of the composites ranged from 3.70 × 10−4 to 5.71 × 10−4 mol/cm3 and 207.81 to 386.17%, respectively. According to the results obtained, the best cure and wear behavior followed by the morphological analysis are observed in NR/30PALF/MWCNT composite. Among the samples tested, NR/30PALF composite exhibited the best performance in both cross‐link density and swelling behavior. It is anticipated that the findings of this study are expected to provide theoretical data for the design and optimisation of high‐performance automotive and footwear applications.Highlights
NR/30PALF/MWCNT hybrid composite exhibited the shortest

The addition of MWCNT improved the wear resistance of the composites
The reinforcement of PALF at 30 phr possessed the lowest swelling ratio and the highest cross‐link density of the composites
The addition of MWCNT decreased cross‐link density of the composites

AbstractAimTo explore white matter (WM) tracts linked to impulsivity using the diffusion magnetic resonance imaging (DMRI) connectometry method.MethodsWe analyzed 218 healthy participants from the Leipzig Study for Mind‐Body‐Emotion Interactions database. Impulsivity correlations with DMRI‐derived WM changes were assessed using Urgency‐Premeditation‐Perseverance‐Sensation (UPPS) Impulsive Behavior Scale subscales: lack of perseverance (PE), lack of premeditation (PM), sensation seeking (SS), and negative urgency. DMRI data were processed using connectometry, adjusting for sex and age, to examine WM tract integrity via quantitative anisotropy (QA). Also, two additional interaction analyses were conducted to separately examine the interaction effect between WM QA, and sex and age in predicting impulsive behavior scores. The significance level in our statistical analyses was set at a false discovery rate (FDR) below 0.05.ResultsQA in the bilateral cerebellum and middle cerebellar peduncle showed a negative association with PE and PM severity (FDR = 0.0004). QA in the middle cerebellar peduncle, corpus callosum body, and forceps major demonstrated a positive association with SS (FDR = 0.0001). Conversely, QA in forceps minor had a positive association with PM (FDR = 0.004), and QA in forceps minor and bilateral cingulum showed a positive association with SS (FDR = 0.0005). Age and sex had no significant effects on the association between WM QA and UPPS subscale scores.ConclusionImpulsivity is linked to distinct WM integrity changes in various tracts, including the corpus callosum, cerebellum, and cingulum, offering insights into the pathophysiology of impulsivity and guiding future research.

Published: October 2024

ABSTRACTBackgroundThe accuracy of administrative codes to capture patients with both primary biliary cholangitis (PBC) and cirrhosis could be challenging because of the potential for incorrect coding due to the old nomenclature “Primary Biliary Cirrhosis.” Therefore, the aim of this study was to examine the positive predictive value (PPV) of International Classification of Diseases (ICD) codes for PBC and cirrhosis.MethodsThis was a retrospective cohort study using data from the VA Corporate Data Warehouse. Eligibility criteria included adult patients diagnosed to have PBC and cirrhosis based on one inpatient or two outpatient ICD 9 or 10 codes, and were validated against chart review of each participant.ResultsWe identified 1408 patients who were found to have ICD codes for both cirrhosis and PBC. The ICD 9/10 codes for PBC and cirrhosis had a PPV of 0.75 (95% CI 0.73–0.75) for cirrhosis, 0.75 for PBC (95% CI 0.73–0.78), and 0.52 (0.50–0.55) for PBC and cirrhosis. When portal hypertension was combined with ICD 9/10 codes, the PPV of cirrhosis improved to 0.92 (0.90–0.94), and that of PBC cirrhosis improved to 0.64 (0.60–0.67). By combining ICD 9/10 codes for portal hypertension and receipt of ursodeoxycholic acid (UDCA), the PPV for cirrhosis improved to 0.91 (0.88–0.94), PBC increased to 0.78 (0.74–0.82), and that for PBC cirrhosis to 0.69 (0.65–0.74).ConclusionsIn a large national cohort, the use of ICD 9/10 codes had modest reliability for identifying participants with PBC and cirrhosis. The PPV for cirrhosis can be improved by incorporating ICD 9/10 codes for portal hypertension with receipt of UDCA.

ABSTRACTPurposeThis study examined the prevalence of headache medicine use among Danish adolescents and explores the link between mental health, frequent headaches, and medicine use for headache. We hypothesized that poor mental health increases headache occurrence, leading to greater medicine use.MethodsThe 2022 Danish Health Behaviour in School‐aged Children (HBSC) study surveyed 5292 students aged 11, 13, and 15. Self‐reported data included headache frequency, medicine use for headache, and five mental health indicators: life satisfaction, emotional symptoms, loneliness, self‐efficacy, and self‐esteem. Multivariate logistic regression analyses assessed the association between mental health indicators and headache medicine use, adjusting for headache frequency.ResultsWeekly headaches were reported by 33.1%, and 43.6% used headache medicine in the past month. Poor mental health correlated with higher headache and medicine use rates. Analyses adjusted for sex, age group, and occupational social class found significantly increased odds ratios (95% confidence interval) for medicine use for headache among students with low life satisfaction (2.27; 1.88–2.75), among students with 2+ emotional symptoms (2.28; 1.92–2.69), students who often felt lonely (2.08; 1.69–2.55), students with low self‐efficacy (1.37; 1.16–1.61) and students with low self‐esteem (1.59; 1.36–1.85). When accounting for headache frequency, the association between poor mental health and medicine use diminished and became nonsignificant.ConclusionsPoor mental health was linked to increased medicine use for headache. The findings suggest that frequent headaches may explain the association between poor mental health and the use of headache medicine. Promoting rational medicine use and enhancing mental health among adolescents is essential.

Published: October 2024

AbstractSequence‐specific endonucleases have been key to the study of the mechanisms and control of DNA double‐strand break (DSB) repair and recombination, and the availability of CRISPR‐Cas nucleases over the last decade has driven rapid progress in the understanding and application of targeted recombination in many organisms, including plants. We present here an analysis of recombination at targeted chromosomal 5′ overhang DSB generated by the FnCas12a endonuclease in the plant, Arabidopsis thaliana. The much‐studied Cas9 nuclease cleaves DNA to generate blunt‐ended DSBs, but relatively less is known about the repair of other types of breaks, such as those with 5′‐overhanging ends. Sequencing the repaired breaks clearly shows that the majority of repaired DSB carry small deletions and are thus repaired locally by end‐joining recombination, confirmed by Nanopore sequencing of larger amplicons. Paired DSBs generate deletions at one or both cut‐sites, as well as deletions and reinsertions of the deleted segment between the two cuts, visible as inversions. While differences are seen in the details, overall the deletion patterns are similar between repair at single‐cut and double‐cut events, notwithstanding the fact that only the former involve cohesive DNA overhangs. A strikingly different repair pattern is however observed at breaks flanked by direct repeats. This change in sequence context results in the presence of a major alternative class of repair events, corresponding to highly efficient repair by single‐strand annealing recombination.

Published: October 2024

AbstractIn recent years, there has been a significant push toward using environment‐friendly composite materials derived from renewable resources. Areca nut husk and bagasse fibers are excellent examples of agricultural by‐products that possess valuable properties for various applications. In this work, three samples containing 23.06%, 28.54%, and 33.33% of areca nut husk and bagasse fibers‐reinforced epoxy matrix (ABFR) hybrid composites were prepared to assess their suitability for use as thermally insulated false ceilings in affordable housing, civil structures, and the automotive industry. The novel hybrid composites were characterized by tensile strength, flexural strength, morphology, thermal conductivity, thermogravimetric analysis (TGA), and percentage of water absorption. The composite containing 23.06% fiber exhibited the lowest thermal conductivity at 0.1631 W/m K and demonstrated excellent thermal insulating properties at 0.03629%. It achieved a maximum tensile strength of 30.05 MPa and a flexural strength of 19.72 MPa. The thermogravimetric analysis indicated that the composites undergo multiple degradation steps; however, they remain stable within the temperature range of 280–328°C. The scanning electron microscope (SEM) observations revealed effective interfacial bonding between the fibers and the epoxy matrix. These characteristics suggest that this hybrid composite could be a suitable option for thermally insulated false ceilings when compared to existing synthetic fiber alternatives.Highlights

Published: October 2024

AbstractOver the past 30 years, there has been an increasing number of documented human infections associated with the protozoan Lophomonas, specifically Lophomonas blattarum, which is considered a relatively rare infection. These infections are primarily associated with states of immune suppression, including those resulting from corticosteroid therapy. We report a 61‐year‐old female patient with a 20‐year medical history of Systemic lupus erythematosus (SLE) who was admitted due to persistent respiratory symptoms that were unresponsive to treatment. The patient was receiving immunosuppressive therapy for SLE. Upon hospitalization, computed tomography of the lungs revealed the presence of centrilobular nodules exhibiting tree‐in‐bud patterns, as well as bronchiectasis, predominantly in the middle and lower lobes. Subsequently, the patient underwent bronchoscopy, during which a BAL sample was obtained. Microscopic analysis of the sample indicated the presence of L. blattarum. Clinicians often focus on the primary symptoms of SLE, but they must also consider the risk of severe respiratory complications like lophomoniasis. This condition is critical to address in the management of SLE patients, who are immunosuppressed due to the disease's nature and its treatment.

AbstractThe development of simple, accurate, responsive, and selective antimicrobial drug analysis platforms is extremely important for biomedical research. Developing a novel electrode material that possesses low detection limit, high sensitivity, and stability continues to be a difficult undertaking. Here, vanadium tungstate nanostones (VWNs) were synthesized by utilizing facile sonochemical method with the aid of urea and ethylene glycol for application in electrochemical sensing of antibiotic drug nitrofurantoin (NFT). Using a distinct analytical methods, the structural and morphological characteristics of the as‐prepared transducer material were described. Further, electrochemical behaviour of modified electrode were analysed using cyclic voltammetry and liner sweep voltammetry. Under the optimal conditions VWNs/GCE electrode exhibited superior electrocatalytic activity towards NFT with linear range (20–160 μM), limit of detection (0.019 μM) with better sensitivity (0.69 μM−1 cm−2). The modified electrode demonstrated remarkable repeatability, reproducibility, and excellent stability, indicating its potential as an electrocatalyst. Ultimately, the suggested electrode was used to measure FLT in real samples like tap water and NFT capsule.
ESG as a nonmarket strategy to cope with geopolitical tension: Empirical evidence from multinationals' ESG performance

Published: October 2024

AbstractResearch SummaryAlthough rising geopolitical tension is critically affecting multinational enterprises (MNEs), our understanding of geopolitics and its effects on corporate strategy is surprisingly limited. This study sheds light on this underexplored topic by examining the environmental, social, and governance (ESG) strategy of foreign MNEs amid tension between their home and host countries. We argue that the media plays a critical role in shaping host‐country public perceptions of such tension. As media‐reported tension increases, foreign MNEs enhance their subsidiaries' ESG performance to alleviate potential institutional pressure from the host‐country public. We further show that historical conflicts positively moderate this relationship, whereas ongoing conflicts serve as a scope condition that diminishes this relationship. This manifests that MNEs attempt to maximize ESG's insurance‐like benefits in coping with geopolitics.Managerial SummaryRising geopolitical tension leading to a less stable global business environment highlights the growing importance of geopolitics and strategic responses of firms. This study explores how host‐country media coverage of geopolitical tension affects foreign MNEs. If host‐country news media reports more tense interactions between MNE's home and host countries, the MNE ex ante is likely to experience heightened pressure from the host‐country public. Thus, we argue and show that MNEs subject to pressure from the host‐country public intensify their ESG efforts to enjoy the insurance‐like benefits of ESG's prosocial initiatives. Our study also shows that both past and ongoing conflicts between home and host countries differentially influence MNE's ESG efforts because the anticipated effectiveness of their strategy is heterogeneous.
The paradox of transfers: Distribution and the Dutch disease
Authors: Behzadan Nazanin , Chisik Richard 
Published: October 2024

AbstractWe develop a new model of international trade with nonhomothetic preferences whereby within‐country income distribution affects the pattern of trade and economic growth. Alternative forms of foreign transfers, such as foreign aid and remittances, interact with the income distribution in dissimilar manners, which in turn generates differences in spending patterns, production patterns, and the pattern of international trade. In a three sector model with international trade and production we show that while remittances foster economic growth, foreign aid can cause economic stagnation. A production shift to the sector with less long‐run growth potential is known as the Dutch disease and in our model the disease is triggered by within‐country income differences and the form of the foreign transfer. We empirically verify these hypotheses with data from a panel covering the years 1991–2009 while controlling for the issues of omitted variable bias and the possible endogeneity of foreign aid and remittances.
H3K27 Acetylation‐Activated GLDC Accelerated the Advancement of Oral Squamous Cell Carcinoma by Suppressing the p53 Signaling Pathway
Authors: Xu Chen , Xu Qingfeng , Yang Haibing 
Published: October 2024

ABSTRACTGlycine decarboxylase (GLDC) has been identified to be dysregulated and plays pivotal roles in various cancers. Besides, studies have suggested that GLDC expression is elevated in oral squamous cell carcinoma (OSCC) and associated with a worse prognosis, but the precise role and molecular mechanism of GLDC in OSCC remain unexplored. The current study first confirmed the high expression of GLDC in OSCC and its correlation with worse survival in patients with OSCC. By knocking down GLDC, it was discovered that the growth and colony formation of OSCC cells, as well as the development of xenograft tumors, were effectively suppressed. In addition, GLDC deficiency inhibited the migration and invasion of OSCC cells in vitro through regulating EMT markers and attenuated lung metastasis in vivo. Mechanistically, GLDC was found to affect the activity of the p53 signaling pathway. GLDC depletion retarded the progression of OSCC by activating the p53 signaling pathway. Moreover, p300 co‐functioned with TFAP2A to induce acetylation of GLDC, which resulted in the upregulation of GLDC in OSCC. To conclude, acetylation‐induced GLDC upregulation facilitated the tumorigenesis and metastasis of OSCC by its inhibition of the activity of the p53 signaling pathway.
