Imbalanced Value Perception Enhances Secondhand Luxury Purchase: Evidence From Chinese Consumers
Authors: Wang Chun‐Chieh , Chen Jie , Fan Wenjian 
Published: November 2024

ABSTRACTThe secondhand luxury market has experienced significant growth in the past few years. Unlike the well‐known knowledge on consumers' luxury consumption, the motivations for purchasing secondhand luxury items remain underexplored. To address this gap, the present study examines how and when Chinese consumers' perceived values affect their purchase intention of secondhand luxury products. We propose that the imbalanced luxury value perception is superior to the balanced one in boosting customer purchase. This hypothesis received convergent support from two studies adopting different methodologies. Specifically, Study 1 was a lab experiment that verified that the imbalance value perception, that is, either a salient financial or symbolic value of a secondhand luxury product, can increase consumers' purchase intention. However, when the two values are highlighted, purchase intention decreases instead. Furthermore, Study 2 adopted a questionnaire survey to test the moderating effects of product risks. Specifically, when the level of product quality (fit) risk is high, a financial‐focused (symbolic‐focused) imbalanced value perception is most effective in improving consumers' purchase intention. This study contributes to the literature on luxury value and risk perception and benefits the marketing practice of secondhand luxury.

Published: November 2024

AbstractBackground and ObjectivesIn the present study, the effect of a pH‐shifting method in combination with heat was investigated for its effects on the resulting surface and functional properties of a commercial pea protein isolate. The pH shifting process was performed at both acidic (pH 2) and alkaline (pH 10) pH and then adjusted back to neutrality. The heat‐treated samples were further subjected to heating and later neutralized at pH 7.FindingsThe results of these treatments indicated that an alkaline pH shifting, as well as its combination with heat, resulted in a significant increase in the solubility of the proteins, whereas an acidic pH shifting, and in combination with heat, reduced the stability of the proteins in solution. Additionally, some functional properties were enhanced by pH shifting, such as foaming capacity or emulsion stability, while other properties showed no alteration or were negatively impacted, such as foaming stability. Furthermore, analysis of the bubble structure of foams using a dynamic foam analyzer revealed that bubble sizes for samples shifted at pH 2 in combination with heat presented the biggest increase in bubble growth over time, creating a less stable foam.ConclusionsThe application of pH shifting and the use of heat can aid in the improvement of pea protein functionality and allow tailoring of these proteins for specific applications.Significance and NoveltyThis study utilized a simple method to achieve modifications in the protein structures, providing insights into the application of pea proteins into food products as emulsifying and foaming agents.
Emerging role of IRE1α in vascular diseases
Authors: Shi Jia , He Fan , Du Xiaogang 
Published: November 2024

AbstractA mounting body of evidence suggests that the endoplasmic reticulum stress and the unfolded protein response are involved in the underlying mechanisms responsible for vascular diseases. Inositol‐requiring protein 1α (IRE1α), the most ancient branch among the UPR‐related signaling pathways, can possess both serine/threonine kinase and endoribonuclease (RNase) activity and can perform physiological and pathological functions. The IRE1α‐signaling pathway plays a critical role in the pathology of various vascular diseases. In this review, we provide a general overview of the physiological function of IRE1α and its pathophysiological role in vascular diseases.

Published: November 2024

AbstractAlumina‐supported PtSn catalysts have been industrialized as the major catalysts for propane dehydrogenation, where Sn serves as an essential promoter. Herein, we synthesized a variety of Sn‐doped alumina supports by regulating the precipitation order of Sn and Al precursors as follows: Sn precursor precipitated before Al, coprecipitated with Al, precipitated immediately after Al, or precipitates after 2 h of Al. The effect of Sn promoter on the surface acidic properties of alumina and, ultimately, on propane dehydrogenation was further investigated. The Sn species introduced by coprecipitation in alumina created additional surface strong acid sites, attributed to more Sn4+ species on the surface, which are able to remain stable during the subsequent treatment. Consequently, the coprecipitated Sn species in the corresponding catalyst donate more electrons to Pt and reduce the metal particle size. As a result, the catalyst with Pt supported on the coprecipitated support (Sn+Al) exhibits superior initial propane conversion (43.2%) and stability (kd = 0.035 h−1). This study provides new insight into the interaction between the two key components, tin promoter and alumina support, of Pt/Sn‐Al2O3 catalysts.

AbstractSoybean [Glycine max (L.) Merr.] biomass and grain yield has increased over the past several decades in the mid‐southern United States. This is attributable to technological advances and improved management strategies. However, a better understanding of biomass accumulation and partitioning is needed to improve our knowledge base of varietal growth habits relative to yield, planting date, and harvest index (HI). Field experiments within a split plot arrangement in a randomized complete block design were established in 2017 and 2018 in Stoneville, MS. The study aimed to evaluate the effect of early (late‐April or mid‐May) and late (late‐May) planting on biomass, HI, and yield amongst eight soybean varieties. Soybean total biomass accumulation was collected at multiple development stages, including V4, R2, mid R5, mid R6, and R8, and partitioned into senesced leaves, pods, and seeds. Overall, the planting date had no effect on yield, HI, and biomass accumulation at any of the growth stages. Yet, the interaction between planting date and variety significantly affected biomass accumulation at the mid R5 stage. Contrarily, the variety selection significantly affected yield, HI, and biomass accumulation at all growth stages except mid R6. The total biomass accumulation at R8 was greatest for Asgrow 46X6, Asgrow 4632, Terral 4857X, Terral 48A76, and Credenz 4748, when pooled over planting dates. Averaged across two planting dates, the greatest yield was produced by Terral 48A76, Asgrow 4632, and Asgrow 46X6. Furthermore, averaged across site‐years, HI was greatest for Asgrow 4632 and Terral 48A76. Based on the results of this study, evaluating soybean HI rather than overall biomass accumulation may be more beneficial for variety selection decisions.
Crop sequence affects horseweed density and productivity in oats
Authors: Schmer Marty , Varvel Gary , Swanson Steve , Fann Ben 
Published: November 2024

Plain Language SummaryDiversified crop rotations can provide many benefits that include greater yield stability, better nutrient cycling, and improved pest management. In a long‐term experiment, we observed weed differences in oat that was the result of whether the previous crop was corn or grain sorghum. Horseweed, a common weed in North America, was more prevalent in oat when the previous crop was corn. We speculate that grain sorghum, considered to have allelopathic compounds, suppressed horseweed the following year better than corn. We show that crop sequence within diversified can result in distinct differences in weed presence and production.

Published: November 2024

AbstractBy virtue of the high reliability of click chemistry, polymers with clickable groups provide a useful platform for the rapid synthesis of polymer materials with diverse functionalities and architectures. However, the polymerization of clickable vinyl monomers with a concurrent regulation on tacticity remains underdeveloped. Herein, we report the successful development of a stereoselective cationic copolymerization of C−C triple bond‐containing vinyl ethers with simple alkyl vinyl ethers by employing confined Brønsted acid as catalyst, which allows for the synthesis of alkyne‐functionalized vinyl ether copolymers with high isotacticity (up to 90 % m), controlled molecular weight, and variable content of C−C triple bonds. Further transformation of the pendant clickable alkyne groups via thiol‐yne click reactions and copper(I)‐catalyzed alkyne‐azide cycloaddition reaction enables a modular access to isotactic polymers with various functional groups.

Published: November 2024

AbstractThe integration of multiple functions within a single fluorescent molecule provides a promising platform for developing versatile, efficient, and cost‐effective materials with enhanced performance across diverse applications. In this study, we introduce TPEC, an aggregation‐induced emission (AIE) molecule derived from tetraphenylethylene‐based tetracarboxylate, which demonstrates multifunctional capabilities, including metal ion sensing and self‐erasable writing. TPEC exhibits amphiphilicity in water, self‐assembling into single‐layer nanosheets with robust blue fluorescence. Notably, the aqueous solution of TPEC displays a fluorescence colorimetric response to Al3+ ions and fluorescence quenching in the presence of Fe3+ ions. Additionally, TPEC powders undergo fluorescence colorimetric changes under mechanical stimulation, enabling self‐erasable writing on prepared paper. This study presents a straightforward strategy for the development of multifunctional luminescent materials based on the self‐assembly of a single‐component fluorophore.

Published: November 2024

AbstractBesides the distinctive features and medicinal benefits of guanidine Schiff bases, the possibility of their use as a sorbent for radioactive contents of effluents was developed in the current study. A series of adsorption experiments were performed with 2,2‐benzene‐1,4‐dildiguanidine di‐salicylate synthesized sorbent from sulphate feed solutions containing UO22+ and ThSO42+ species each separately. Infrared studies demonstrated that the sorbent links to both actinides via the azomethine nitrogen atom and the hydroxyl groups on the sorbent. Thermal analyses were also performed. Using the greatest adsorption results, UO22+ and ThSO42+ were able to bind to modified guanidine Schiff base (MGSB) sorbent with uptake capacities of 98 and 54 mg/g respectively. The maximal uptake was achieved at pH 5.5 and 3.5 and 90 min contact time for UO22+ and ThSO42+, respectively. The equilibrium adsorption results for UO22+ and ThSO42+ were in good agreement with Langmuir isotherm and the pseudo‐second‐order reaction model and demonstrated the endothermic nature and kinetic improvement by increasing temperatures. All kinetic and isotherm results demonstrated the chemical adsorption of both UO22+ and ThSO42+ at the MGSB active sites. Positive ∆H (40.54 and 40.16 kJ/mol for UO22+ and ThSO42+, respectively) proved the endothermic nature of the adsorption process.

Published: November 2024

AbstractObjectiveWe aimed to test whether T‐wave alternans (TWA), which is a marker of susceptibility to ventricular fibrillation, is abnormal in children with Angelman syndrome (AS) compared with typically developing children (TDC), and whether it can be used as a biomarker of AS.Materials and MethodsUsing surface electrocardiogram (ECG), we calculated TWA in AS and compared it between AS and TDC (Wilcoxon rank sum test). We then performed logistic regression to test TWA ability to distinguish AS from TDC.ResultsWe observed higher TWA in AS than TDC (44 vs. 33 uV, p = 0.009), while heart rate did not differ (p = 0.26), nor its variability (p = 0.72). TWA values enabled discrimination between AS and TDC (p = 0.0008) with accuracy of 81%, positive predictive value of 72%, and negative predictive value of 100%.InterpretationOur findings suggest that ECG in children with AS contains evidence of acquired cardiac abnormality via pathologically increased TWA.

Published: November 2024

AbstractCharcot‐Marie‐Tooth (CMT) disease represents a diverse group of inherited neuropathies with a broad spectrum of symptoms. It is the most prevalent inherited neuropathy, with an estimated prevalence ranging from 9.7 to 82 cases per 100,000 individuals. Despite this, CMT comprises only 118 of 853 inherited neuropathy entries in the Online Mendelian Inheritance in Man (OMIM) database. This comprehensive review offers a thorough examination of CMT's clinical features, subtypes, genetic underpinnings, and pathomechanisms in pediatric cases. CMT typically manifests as progressively worsening muscle weakness and atrophy, primarily affecting the distal extremities. Patients may also experience foot and ankle deformities, hand atrophy, and other systemic issues. To accurately diagnose CMT, a detailed family history, comprehensive clinical evaluation, nerve conduction studies, and relevant genetic testing are essential. Importantly, establishing a differential diagnosis is crucial during evaluation to rule out other conditions with similar presentations. This review aims to provide clinicians with a valuable resource for diagnosing and managing CMT, emphasizing the need for a streamlined and standardized approach considering advancements in genetic testing and the identification of various subtypes.
The Analysis of Vibrational Spectra: Past, Present and Future
Authors: Parker Stewart F. 
Published: November 2024

AbstractVibrational spectroscopy can be said to have started with the seminal work of Coblentz in the 1900s, who recorded the first recognisable infrared spectra. Today, vibrational spectroscopy is ubiquitous and there are many ways to measure a vibrational spectrum. But this is usually only the first step, almost always there is a need to assign the resulting spectra: “what property of the system results in a feature at this energy”? How this question has been answered has changed over the last century, as our understanding of the fundamental physics of matter has evolved. In this Perspective, I will present my view of how the analysis of vibrational spectra has evolved over time. The article is divided into three sections: past, present and future. The “past” section consists of a very brief history of vibrational spectroscopy. The “present” is centered around ab initio studies, particularly with density functional theory (DFT) and I will describe how this has become almost routine. For the “future”, I will extrapolate current trends and also speculate as to what might come next.

ABSTRACTObjectivesParents are responsible for their children's oral health. This study evaluated parents' knowledge, attitudes, and performance on their children's oral health before and after an educational intervention and the impact of COVID‐19 on these variables.Material and MethodsThis quasi‐experimental study included 227 children aged 6–8 years who were referred to 11 Shiraz medical centers from July to December 2021. Data were collected from questionnaires and interviews. After completing the questionnaire, oral health education was provided immediately and then monthly thereafter using dental models and pamphlets. After 3 months, a questionnaire assessed the education's effectiveness. Data were analyzed using independent t‐tests, one‐way analysis of variance (ANOVA), paired t‐tests, and Pearson's correlation.ResultsA total of 163 participants (71.80%) completed all phases, including the second questionnaire. Participants showed moderate knowledge (77.30%), attitude (89.00%), and performance (80.40%). Neither knowledge nor attitude before the intervention had a significant association with demographic characteristics. Parents' education, number of children, and maternal employment were significantly associated with performance (p = 0.002, p = 0.040, p < 0.001, respectively). The intervention significantly enhanced these variables (p < 0.001). In terms of COVID‐19, 72.40% of participants expressed good knowledge about transmission, 52.80% showed moderate concern, and 54% had poor performance. Parental knowledge, attitude, and performance changed significantly following the intervention (p = 0.030, p < 0.001, p < 0.001, respectively).ConclusionsEducational intervention significantly improved parents' knowledge, attitudes, and performance toward children's oral health. Because of the poor performance of parents during the COVID‐19 pandemic, we recommend the implementation of continuing education and preventive oral health programs.

Authors: Singh Tanuja , Ghimire Tika R. , Dhungana Manoj 
Published: November 2024

ABSTRACTBackgroundPatients with high dental anxiety are found to visit dental offices less frequently and have a higher number of severely diseased teeth so they are at a greater need for intensive oral care and rehabilitation.ObjectivesThe aim of this study was to assess the prevalence of dental anxiety and its impact on the dental status of Nepali adult patients.Material and MethodsA semi‐structured questionnaire of the Modified Dental Anxiety Scale (MDAS) in the Nepali version was used for data collection. The data analysis was done using Statistical Package for Social Sciences (SPSS IBM, Chicago, IL, USA, version 24). Variables were calculated as frequency and percentage, while the comparisons of different factors were done using the ANOVA and t‐test. A difference with p < 0.05 was considered statistically significant.ResultsThe study population consisted of 446 subjects, among them 205 were male (45.96%), 241 were female (54.04%), 357 (80.04%) were married, and 222 (49.78%) were employed. The mean age of the patients was 41.24 years (ranging between 18 and 79 years). Only 41 subjects (9.19%) showed high dental anxiety (MDAS ≥ 19). The mean MDAS for the total study population was 10.81. The highest mean MDAS was seen in the age group 30–39 (11.78) and the lowest mean MDAS was seen in the age group 40–49 (9.64). While comparing dental anxiety among genders, dental anxiety was higher in females (mean MDAS = 11.78) compared to males (mean MDAS = 9.67). Patients having high dental anxiety had a significantly higher number of decayed teeth (p‐value = 0.001, t‐test).ConclusionOral health and dental status both are negatively affected by dental anxiety. It interferes with dental attendance, service delivery, prevention of dental diseases, and early diagnosis. Thus, dental practitioners have a major role to play in the management of dental anxiety.
Closing the Loop: Low‐Waste Phosphorus Functionalization Enabled by Simple Disulfides

Published: November 2024

AbstractUseful monophosphorus products are obtained from both white and red phosphorus via a simple strategy involving initial oxidation by aryl disulfides followed by quenching with nucleophiles. Direct transformations of elemental phosphorus are usually very challenging, forcing chemists to instead rely on inefficient and hazardous multi‐step methods. However, here they are achieved using inexpensive and easy‐to‐handle reagents, providing access to diverse P−C, P−N and P−O bonded products in good yields. By isolating the thiolate byproducts of these reactions, a simple, closed loop can be achieved that produces only minimal, benign waste byproducts, in contrast to other direct methods. This closed loop can even be elaborated into a true (electro)catalytic cycle, which is extremely rare in the field of elemental phosphorus functionalization.

Published: November 2024

ABSTRACTInhibition of SIRT3 triggered differentiation of multiple myeloma (MM) cells. In discovery of potent SIRT3 inhibitors for cancer differentiation therapy, structural modification was performed on the previously developed lead compound S27. A total of 49 compounds divided into two series were designed and synthesized. In the enzyme inhibitory assay, several molecules (A7, A13, B15, and B26) exhibited potent SIRT3 inhibitory activity and selectivity. Significantly, representative compounds, especially A7, promoted differentiation of MM cells from cancer phenotype to normal cells, accompanied by increased expression of antigen CD49e, human immunoglobulin light chain λ‐IgLG and κ‐IgLG. Additionally, molecule A7 reversed growth factor IL‐6 induced MM cell proliferation, improved the antiproliferative activity of Ixazomib and increased the apoptotic rate of MM cells treated with Ixazomib. Collectively, potent SIRT3 inhibitors with MM cell differentiation potency were developed for the cancer therapy used alone or in combination.
