Published: November 2024

AbstractBackgroundPopularity in adolescence has been the subject of considerable empirical inquiry over the last two decades. As research on this dimension of social experience evolved, fundamental shifts occurred in the modalities through which adolescents communicate. Social networking platforms, instant messaging applications, and other forms of social media emerged as organizing features of adolescent peer groups.ObjectiveIn the current paper, we present a systematic review and meta‐analysis examining evidence that social media activity is associated with both popularity and goals for becoming popular.MethodsSyntheses were conducted based on 34 effect sizes from 12 studies (N = 7776; 4037 girls and 3739 boys) using three‐level Meta‐analytic techniques.ResultsAverage effect sizes across studies were of small to medium magnitude and were not influenced by Meta‐analytic moderators. Although the findings provide support for expected positive associations between social media activity and popularity, unresolved questions remain.

ABSTRACTType 2 diabetes mellitus is a global health problem, placing patients at a higher risk of developing cardiovascular diseases and cancer. This study investigates the antidiabetic potential of Cassia bakeriana bark extracts and fractions. We evaluate their ability to inhibit α‐amylase and α‐glucosidase enzymes and advanced glycation end‐products (AGEs). The antioxidant potential was also examined. Extracts were prepared through maceration with hexane (HE) and ethanol (EE), and the fractions were obtained via liquid–liquid extraction from EE. Anti‐enzymatic, anti‐glycation, antioxidant, and cytotoxic assays were conducted in 96‐well plates using different concentrations of samples to determine the half‐maximal inhibitory concentration (IC50). Active samples were further analyzed using HPLC‐(−)‐ESI‐MS/MS. The ethyl acetate fraction (EAF) demonstrated a high percentage of α‐amylase inhibition (94.0%) with a promising IC50 value of 1.05 μg mL−1. Additionally, EAF displayed 61.5% inhibition of α‐glucosidase, with an IC50 value of 537 μg mL−1. The EE, EAF, and n‐butanol fraction (BF) exhibited strong anti‐glycation capacities. Furthermore, the EE, EAF, BF, and dichloromethane fractions showed promising antioxidant activity using the DPPH and ORAC methodologies. Cytotoxic activity was also evaluated with Vero cells, revealing no adverse effects on cell viability (CC50 > 512.0 μg mL−1). Active samples predominantly comprised proanthocyanidins, flavonoids, and anthraquinone, representing the main constituents of C. bakeriana bark. This study provides the first assessment of the antidiabetic potential of C. bakeriana bark and a comprehensive analysis of the chemical composition of its active extracts and fractions, offering hope for future treatments.

AbstractObjectivesWe aimed to analyze the episodes of esophageal food bolus impaction (EFI) occurred over a time of 15 years in children admitted to a large pediatric emergency department (PED), documenting their clinical presentation, underlying pathology, management, biopsy rate, and follow‐up visits. Additionally, to combine our institutional experience with the existing literature, a comprehensive review was conducted.MethodsWe reviewed the medical records of all children presenting to our PED with EFI from 2010 to 2024. The comprehensive review was guided by the Preferred Reporting Items for Systematic Reviews and Meta‐Analysis statement for systematic reviews. Electronic databases including PubMed/Medline and EMBASE were screened. The data obtained was synthesized to map out the actual status and current literature on pediatric EFI.ResultsWe identified 54 cases of EFI. Overall, 22 patients (41%) had underlying pathology. Previous episodes were reported in 14 cases (26%). Urgent endoscopy was performed in 31 cases (57%). The presence of underlying pathology was associated with the need for endoscopic removal (p = 0.013), as well as the history of previous episodes (p = 0.016). Biopsies were performed in 14 cases (26%). Pediatric gastroenterologists showed a higher rate of performed biopsies compared to surgeons, as well as higher rate of follow‐up visits. An underlying disease was found during later clinical follow‐up in 5 out of 54 cases of EFI (9%). A comprehensive review of 16 studies revealed high rates of underlying pathology and low rates of biopsies and follow‐up visits among children with EFI.ConclusionIncreased vigilance in identifying underlying pathologies in children with EFI is crucial. The importance of performing biopsies, regardless of prior anatomical conditions, and the need for ongoing follow‐up to ensure timely and accurate diagnoses should be addressed through shared protocols.

Published: November 2024

ABSTRACTArene Candide Cave, a key site for Western Mediterranean prehistory, is famous for the discovery of the richly adorned Mid–Upper Palaeolithic burial of the ‘Young Prince’ and for its use as a burial site at the end of the Pleistocene (Late Epigravettian). In both contexts, red ochre was a conspicuous element of the burial practices. Unfortunately, few provenance studies and analytical data are available for the pigments recovered in the cave. Likewise, the geographical and geological origins of these colouring materials, which are naturally abundant in the Liguro‐Provençal Arc, have received little to no attention despite their technical and symbolic value. During the 2008–2013 archaeological excavation at Arene Candide Cave, micromorphological samples were collected from the Upper Palaeolithic portion of the 1940s stratigraphic profiles, permitting a first description of site formation processes during the Gravettian. This led to the recognition of a Late Gravettian layer characterized by poorly sorted sediment rich in very small ochre fragments. This study establishes the provenance of these ochre fragments through the combined use of optical microscopy, scanning electron microscopy and X‐ray diffraction. The results reveal a strong correspondence between the Arene Candide ochres and local ore sites, which were never considered before as potential sources. The mineralogical composition of the samples, characterized by the presence of barium sulphate and iron oxides, indicates that the Finalese area (NW Liguria) in which the site is located was the most likely source of the colouring pigments used by the Upper Palaeolithic hunter‐gatherers of the Arene Candide Cave.

Published: November 2024

AbstractCoherent wave control is of key importance across a broad range of fields such as electromagnetics, photonics, and acoustics. It enables us to amplify or suppress the outgoing waves via engineering amplitudes and phases of multiple incidences. However, within a purely spatially (temporally) engineered medium, coherent wave control requires the frequency of the associated incidences to be identical (opposite). In this work, this conventional constraint is broken by generalizing coherent wave control into a spatiotemporally engineered medium, i.e., the system featuring a dynamic interface. Owing to the broken translational symmetry in space and time, both the subluminal and superluminal interfaces allow interference between scattered waves regardless of their different frequencies and wavevectors. Hence, one can flexibly eliminate the backward‐ or forward‐propagating waves scattered from the dynamic interfaces by controlling the incident amplitudes and phases. The work not only presents a generalized way for reshaping arbitrary waveforms but also provides a promising paradigm to generate ultrafast pulses using low‐frequency signals. It has also implemented suppression of forward‐propagating waves in microstrip transmission lines with fast photodiode switches.

AbstractVolumetric imaging, which supports quantitative and comprehensive assessment of a 3D sample from an entire volume, has attracted tremendous attention in biomedical research. Fluorescence imaging techniques, such as optical sectioning and light sheet microscopy, enable to reconstruct the 3D distribution of chemicals within a sample. However, current methods rely on exogenous labels, from which considerable perturbation may be introduced in living systems. Raman imaging offers a feasible solution to visualize components in biological samples in a label‐free manner. Besides, the integration of Raman microscopy with 3D approaches will benefit the research of biomedical samples on novel devices, which is dominated by the strongly enhanced spatial resolution, imaging speed, and overall field of view as well as complemented more details of samples. In this overview, recent achievements in 3D visualization of biological samples from the Raman perspective, are explored including scanning mechanism, light sheet, tomography strategy, compressive sensing, holography, and tissue clearing. Importantly, these platforms are compatible with biomedical research, thus allowing the imaging of chemical constituents and the distribution of samples in a whole volume. As a unique volumetric imaging tool for biological discovery, these methods may provide a strategy to accelerate new discoveries across diverse fields of research.

Published: November 2024

AbstractCells coordinate their activity and regulate biological processes in response to chemical signals. Mimicking natural processes, control over the formation of artificial supramolecular materials is of high interest for their application in biology and medicine. Supramolecular material that can form in response to chemical signals is important for the development of autonomously responsive materials. Herein, a supramolecular hydrogel system is reported enabling in situ generation of hydrogelators in response to a specific chemical signal. Using self‐immolative chemistry, spatial control over the formation of supramolecular hydrogel material and structured free‐standing hydrogel objects via providing H2O2 locally is demonstrated. In addition, a hybrid system is developed enabling in situ generation of the H2O2 by the action of an enzyme and glucose, providing an extra handle for the development of an intelligent soft material. This generic design should enable the use of various (chemical)stimuli that can be obtained via coupling different stimuli and various chemical and/or biological markers and appears a versatile approach for the design of smart artificial soft materials that can find application in theranostic purposes.
Side‐Chain Engineering of Boron β‐Dialdiminate Homopolymer for Solvent‐Dependent Emission Properties
Authors: Ito Shunichiro , Sakai Yuki , Tanaka Kazuo 
Published: November 2024

AbstractLuminescent materials that respond to changes in microscopic chemical conditions are essential for visualizing and evaluating molecular environments. Boron complexes are often employed as robust scaffolds for constructing such responsive systems because of their inherent stimuli‐responsive properties. However, in the case of nonresponsive luminophores, the absence of these intrinsic features limits their range of applications. In this study, environment‐responsive luminescent homopolymers based on the boron β‐dialdiminate complex are developed, which is intrinsically less responsive, by introducing optimized side chains. As a key finding, the triethylene glycol‐decorated polymer exhibits more intense luminescence in chloroform but weaker luminescence in N,N‐dimethylformamide. Structural analyses using NMR and size‐exclusion chromatography suggest that this polymer forms larger aggregates in polar solvents because of the solvophobicity of its main chain, while the polar side chains assist in maintaining adequate dispersibility of these aggregates. Photophysical measurements indicate that interchromophore interactions within the aggregates should be responsible for the reduced luminescence in polar solvents. These findings suggest that side‐chain engineering should be an effective strategy for creating stimuli‐responsive polymers from otherwise nonresponsive luminophores.

AbstractNetwork approaches to psychopathology have become increasingly common in mental health research, with many theoretical and methodological developments quickly gaining traction. This article illustrates contemporary practices in applying network analytical tools, bridging the gap between network concepts and their empirical applications. We explain how we can use graphs to construct networks representing complex associations among observable psychological variables. We then discuss key network models, including dynamic networks, time‐varying networks, network models derived from panel data, network intervention analysis, latent networks, and moderated models. In addition, we discuss Bayesian networks and their role in causal inference with a focus on cross‐sectional data. After presenting the different methods, we discuss how network models and psychopathology theories can meaningfully inform each other. We conclude with a discussion that summarizes the insights each technique can provide in mental health research.

AbstractThe Stirling engine is a high‐efficiency externally heating piston engine. The self‐lubricating properties of polytetrafluoroethylene (PTFE) are crucial for the operation of Stirling engines. Three PTFE composites filled with different contents of carbon fiber (CF), polyimide (PI) and nano‐zirconia (nano‐ZrO2) were prepared and their mechanical, friction and wear properties were investigated. The results showed that the density of CF‐containing PTFE composites was significantly reduced by 1.46% to 6.9% compared to neat PTFE. Meanwhile, the incorporation of fillers greatly enhanced the hardness by more than 21.4% over the hardness of neat PTFE. In addition, the friction coefficients of three PTFE composites were lower than those of neat PTFE, and the wear rate of these composites was three orders of magnitude lower than that of neat PTFE. In particular, the wear rate of PTFE filled with CF and PI at high pressure (2 MPa) and high velocity (4 m/s) was only 1.24 × 10–6 mm3/Nm. The wear morphology was also analyzed by scanning electron microscopy and energy‐dispersive x‐ray spectroscopy. It was found that the addition of CF and PI in PTFE has the most pronounced improvement on tribological performances. The synergistic effect of CF's mechanical reinforcement and PI's adhesive properties reduces the wear of the matrix, resulting in excellent wear resistance of PTFE composites.Highlights
The compressive strength of PTFE was reinforced by CF and nano‐ZrO2.
CF can lower the density and significantly enhance hardness of PTFE.

Published: November 2024

AbstractTo achieve new current collector (pantograph strip, electric brush) with easy industrialization and high strength‐toughness, carbon fiber and copper fiber reinforced phenol‐formaldehyde (Cuf/Cf/PF) composite is fabricated by over‐lapping and hot‐pressing processes. Cuf/Cf/PF composite has compact structure and good interfacial bonding between fibers and resin matrix. Cuf/Cf/PF composite is superior to carbon skateboard in terms of electrical conductivity, mechanical strength, and friction behavior. As the carbon fiber content increases, fracture failure mechanism of Cuf/Cf/PF composite transforms from plastic failure into brittle fracture. Wear mechanism is studied by combining electrical contacting and sliding friction, and appropriate arc discharge (2.48%) is benefit for the resin‐based composite to form a smooth tribolayer, but high arc discharge rate (4.83%) rapidly deteriorates wear condition on the worn surface.Highlights
Carbon fiber and copper fiber mixing reinforce resin‐based composite.
Cuf/Cf/PF composite has high strength‐toughness and low friction.
Fracture failure mode changes to brittle fracture with increasing carbon fiber.
Wear mechanism includes electrical contacting and sliding friction.
Appropriate arc discharge improve friction performance of resin‐based composite.

ABSTRACTPurposeMYRF‐related cardiac‐urogenital syndrome (MYRF‐CUGS) is a rare condition associated with heterozygous MYRF variants. The description of MYRF‐CUGS phenotype is mostly based on postnatal cases and 36 affected individuals have been published so far. We aim now to delineate the prenatal phenotype of MYRF‐CUGS by reporting clinical data from fetuses and neonates with a pathogenic MYRF variant.MethodsDetailed radiographic, pathological, clinical, and molecular data from 12 prenatal cases were collected through an international collaborative study. Adding the five fetuses previously published, we were able to study a cohort of 17 cases.ResultsMain ultrasound‐accessible manifestations of MYRF‐CUGS include congenital heart defects (13/17, 76%), congenital diaphragmatic hernia (10/17, 59%) and disorders of sexual differentiation in 46, XY fetuses (7/14; 50%). Postnatal examination and/or autopsy data highlighted additional birth defects and neurological findings with a large spectrum of severity. Molecular results revealed ten previously unpublished variants, one missense and nine predicted truncating variants (three frameshift, three nonsense and three splice site variants).ConclusionWe report the first prenatal cohort of MYRF‐CUGS, allowing us to further characterize the variable expressivity of this rare disorder in fetuses. Severe congenital anomalies with a poor prognosis are more frequent than previously described in postnatal cases. Our data suggest that MYRF‐CUGS is characterized by a recurrent recognizable malformative association, accessible to prenatal diagnosis, with a significant intrafamilial phenotypic variability making genetic counseling challenging.

ABSTRACTEducators and school staff are critical to recognizing and supporting students' mental health, but frequently do not have the training to confidently bring mental health literacy into the classroom or assist students who experience distress. Moreover, few free, easily accessible trainings are available for this audience. Classroom Well‐being Information and Strategies for Educators (Classroom WISE) is a free, K‐12 mental health literacy training package that includes a self‐paced online course, video library, and resource collection. Using pre‐ and postcourse anonymous surveys from over 2000 educators, school mental health professionals, and school staff who completed Classroom WISE, this study found high levels of satisfaction, significant increases in mental health literacy knowledge, high perceived importance of mastering skills to promote student well‐being, and increased preparedness to implement mental health‐related strategies. Participants reported intentions to bring mental health literacy into the classroom, and identified barriers and facilitators to using Classroom WISE that leaders can respond to or employ when moving to implement Classroom WISE across a school or district. School district or school‐wide use of Classroom WISE can assist in building a safe and supportive school environment and help students in need to access mental health services.
