Abstract“Thermoreversible Structurally Recoverable Dual‐Network Elastomer Hydrogel,” Macromolecular Materials and Engineering 305, no. 1 (2020): 1900633, https://doi.org/10.1002/mame.201900633.The above article, published online on 03 December 2019 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor‐in‐Chief, David Huesmann; and Wiley‐VCH GmbH. The retraction has been agreed after an investigation took place when the authors requested a correction to the article, admitting they‐had accidentally reused an image they previously published. Upon further review, the Editor‐In‐Chief saw that this reused image was‐also clearly manipulated by the authors to create Figure 7b by rotation plus the removal of cells from the original image seen both in Figure 7a and also in the previous journal article figure. Upon questioning, the authors acknowledged they‐had edited the previously published image. As a result, the figures, data, and conclusions are considered unreliable and therefore the article must be retracted.

Authors: Nasr Lina I. , Mousavi Sahar , Michaelidou Nina 
Published: November 2024

ABSTRACTWhile there is pervasive research on virtual influencers (VIs) and their impacts on consumer behaviors, there is a lack of understanding of their effects on followers' wellbeing. Drawing on social comparison theory, in this study, we examine how followers self‐compare with VIs and what the effects of this process are on their wellbeing. Based on a qualitative study, involving 31 interviews with followers of VIs on Instagram, we found that they experience both upward and downward comparison. The upward comparison made them feel envious, jealous (i.e., contrastive), or inspired, optimistic, and admired (i.e., assimilative) while the downward assimilative comparison made the followers worry or feel sympathy with the VI they follow. Moreover, we found another set of emotions that can be triggered by the process of social comparison with a VI, such as feelings of shame due to the nature of the influencers not being human. Individuals cope with the negative effects of self‐comparing through emotional and behavioral regulations.
Physiological Effects of TolC‐Dependent Multidrug Efflux Pumps in Escherichia coli: Impact on Motility and Growth Under Stress Conditions
Authors: Di Maso Amanda M. , Ruiz Cristian 
Published: November 2024

ABSTRACTEnterobacteriaceae possess eight TolC‐dependent multidrug efflux pumps: AcrAB‐TolC, AcrAD‐TolC, AcrEF‐TolC, MdtEF‐TolC, MdtABC‐TolC, EmrAB‐TolC, EmrYK‐TolC, and MacAB‐TolC, which efflux bile salts, antibiotics, metabolites, or other compounds. However, our understanding of their physiological roles remains limited, especially for less‐studied pumps like EmrYK‐TolC. In this study, we tested the effects on swimming motility and growth under stress conditions of Escherichia coli mutants individually deleted for each inner‐membrane transporter component of all eight TolC‐dependent pumps, a mutant deleted for the AcrB‐accessory protein AcrZ, and a mutant simultaneously deleted for all eight pumps (ΔtolC). We found that all mutants tested, except the ΔemrY and ΔacrZ mutants, displayed increased swimming motility. Additionally, the loss of each individual TolC‐dependent pump or AcrZ did not reduce growth and sometimes even enhanced it compared to the parental strain under various growth conditions: temperature (LB at 25, 30, 37, and 42°C), pH (LB at pH 6.0, 7.4, and 9.0; and LB buffered to pH 6.0, 7.4, and 8.25), LB with limited air exchange, and nutritional stress (M9‐glucose or M9‐glycerol). In contrast, the ΔtolC mutant grew significantly slower than the parental strain under all conditions tested except in LB‐TRIS pH 7.4 and LB with limited air exchange. Overall, these findings indicate that while individual TolC‐dependent pumps are generally dispensable for growth under many stress conditions in the absence of antimicrobials, possibly due to their partially overlapping substrate profiles, TolC‐dependent efflux is required for maximal growth under most conditions.
The Nexus Between De‐Globalization and OFDI From Emerging Economies: Moderating Roles of Institution and Government
Authors: Yang Jinjuan , Zeng Yan , Li Rui 
Published: November 2024

ABSTRACTThe recent wave of de‐globalization has slowed the outward foreign direct investment (OFDI) process globally, with varying effects across countries. Using panel data from 25 emerging economies between 1980 and 2018, we examine the impact of de‐globalization on OFDI. Our findings show that higher de‐globalization pressure from developed countries drives emerging economies to invest more globally. Threshold regressions reveal that this positive effect is significant only when a minimum GDP threshold is met. Moreover, better institutional quality and increased government involvement strengthen the positive impact of de‐globalization on OFDI.
Blockchain Adoption and Collaborative Emission Reduction in Vertical‐Shareholding Supply Chain
Authors: Wu Xue‐Yan , Chi Xue , Pu Xujin 
Published: November 2024

ABSTRACTThis study investigates the role of blockchain technology in collaborative emission reduction in vertical‐shareholding supply chains. The collaborative emission reduction decisions of the manufacturer and retailer are examined for four scenarios of whether or not to adopt blockchain technology in the manufacturer‐ and retailer‐led supply chain. The results show that under the manufacturer‐led, they have incentive alignment to adopt blockchain technology when the unit cost of using blockchain technology is low and the retailer's misrepresentation factor is high, regardless of the manufacturer's shareholding ratio. However, under the retailer‐led, their incentive alignment is closely related to the manufacturer's shareholding ratio.

Published: November 2024

ABSTRACTBackgroundWhen the SRY gene is present in a 46,XX fetus, some degree of testicular development is expected. Our laboratory performed prenatal genetic testing for a fetus that had screened positive for Y chromosome material by noninvasive prenatal screening (NIPS) but that had apparently typical female development by ultrasound imaging. The aim of this study was to determine the clinical relevance of the NIPS results.MethodsWe analyzed fetal material obtained via amniocentesis procedure by G‐banding, microarray, and fluorescence in situ hybridization (FISH). Optical genome mapping (OGM) was also performed.ResultsG‐band analysis revealed a normal 46,XX karyotype. Microarray and FISH analyses together detected an SRY+ gain of 5.7 Mb from terminal Yp that was translocated to terminal Xq, with a loss of 1.6 Mb from terminal Xq. The final karyotype was 46,X,der(X)t(X;Y)(q28;p11.2). Prenatal ultrasound and postnatal physical examination revealed apparently typical female genitalia. The Xq deletion encompassed a gene, IKBKG, that is sensitive to loss of function, suggesting that preferential inactivation of the derivative X chromosome allowed for typical female development. OGM software did not directly identify this translocation.ConclusionThis case demonstrates how the SRY gene may be present in a 46,XX biological female without differences of sexual development.
Youth Mental Health: The Role of Culture & KTE Approaches in Expanding the Research Workforce
Authors: Anderson Brandi , Bloxom Quincy 
Published: November 2024

ABSTRACTDespite efforts to expand the youth mental health workforce, disparities continue to persist in service provision, the effectiveness of existing programs and practices, and in research. While there is no quick fix to rectify these issues, expanding the research workforce can serve as a preliminary step in reducing many of the disparities that exist. The current work highlights the necessity for increased efforts to recruit a population of experts (i.e., practitioners) into the research workforce that possesses a level of knowledge and expertise largely untapped by research producers. Furthermore, knowledge transfer and exchange (KTE) methodologies are offered as innovative approaches that can be harnessed to facilitate this change. To provide rationale for expanding not only the research workforce but reimagining historical notions of what research is, and who qualifies as belonging in this space, with examples of action steps that can be utilized by producers to attract practitioners. The use of KTE and related approaches to attract practitioners to research has positive implications including but not limited to expanding the youth mental health workforce.
Improving B1+$$ {B}_1^{+} $$‐inhomogeneity tolerance by resolving non‐bijection in MP2RAGE R1 mapping: A 2D look‐up table approach demonstrated at 3 T
Authors: Ruijters Lenno , Lund Torben Ellegaard , Vinding Mads Sloth 
Published: November 2024

AbstractPurposeRegarding in vivo, robust longitudinal relaxation rate (R1) mapping, the goal of the present paper is two‐fold. First, to verify that non‐bijective mapping in magnetization‐prepared 2 rapid gradient echo (MP2RAGE) imaging can be resolved through a two‐dimensional look‐up table approach. Second, that the expanded parameter space from this can be used to improve ‐inhomogeneity tolerance without other prerequisites.TheoryBy deriving a second contrast from the magnitude images of the MP2RAGE acquisition, ambiguities in the original MP2RAGE image resulting from non‐bijective transfer curves can be resolved. Such ambiguities may occur when protocols are optimized, such as for higher ‐inhomogeneity tolerance. A 2D look‐up table approach combines the available information to resolve these ambiguities during mapping.MethodsAt 3 T, we acquired MP2RAGE images with standard acquisition parameters and (non‐bijective) parameters optimized for ‐inhomogeneity tolerance. From 3 subjects across multiple sessions, we assessed the ‐inhomogeneity tolerance through excitation‐pulse amplitude scalings.ResultsThe R1 maps resulting from the ‐optimized protocols showed greatly reduced effects across images but without additional scanner time. Meanwhile, these maps could only successfully be derived by a 2D look‐up table approach.ConclusionWe show that it is possible to optimize for ‐inhomogeneity tolerance in MP2RAGE through sequence‐parameter settings, while still successfully estimating the R1 map with a two‐dimensional look‐up table approach. This without the need for an additional map. The increased parameter space enabled by the two‐dimensional look‐up table approach may further be used to adjust MP2RAGE acquisitions for improved scan times, signal‐to‐noise ratio, and/or contrast‐to‐noise ratio.

ABSTRACTBone tissue engineering (BTE) has emerged as a promising approach for the regeneration and repair of bone defects caused by trauma, disease, or aging. This review provides an overview of recent advancements in BTE, with a focus on the development and application of biomaterial‐based scaffolds, including natural (e.g., collagen, chitosan), synthetic (e.g., polylactic acid [PLA], polycaprolactone [PCL]), and composite materials (e.g., hydroxyapatite‐based composites). It discusses their properties, benefits, and limitations. Additionally, this review examines innovative fabrication strategies such as 3D printing, electrospinning, and freeze‐drying, which enhance scaffold customization and performance. This review aims to provide insights into future directions of BTE research and its potential applications in regenerative medicine. Functionalization strategies, including surface modifications, coating, and the incorporation of growth factors and cells, are reviewed for their roles in improving scaffold bioactivity. In vivo and in vitro research have demonstrated the therapeutic promise of these scaffolds, while current clinical trials offer insights into their translational use. Challenges facing the translation of these technologies into clinical practice are also highlighted.
Poly(Vinylidene Fluoride‐Hexafluoropropylene) Composites With Carbon Based Nanofillers for Electromagnetic Interference Shielding
Authors: Langrock Alex , Kareem Haval , Auletta Jeffrey T. 
Published: November 2024

ABSTRACTIn the current work, a series of flexible polymer matrix composites (PMCs) based on poly(vinylidene fluoride‐hexafluoropropylene) (PVDF‐HFP) as the polymer matrix and carbon nanofillers, namely single‐walled nanotubes (SWCNT) or carbon blacks (CB), were fabricated via a facile preparation method of blending and solution casting. The electrical conductivity, morphology, dielectric constant, mechanics, and electromagnetic interference (EMI) shielding properties of the composite films were adjusted by varying the carbon type (CB = Ketjenblack, Vulcan, or SWCNT = Tuball) and amount (0.1–15 wt%). The influence of the conductive nanofillers on the EMI shielding effectiveness (SE) and microwave absorbing properties in the X‐band frequency range (8–12 GHz) were investigated. By increasing the carbon content, the EMI shielding properties of the composite films were improved due to an increase in the magnitude of the electromagnetic properties. As the loading of these carbon fillers approach the percolation threshold, the dielectric constant of the composite can dramatically increase because of the construction of a microcapacitor network. However, these nanofillers/polymer composites generally have high dielectric loss near the percolation threshold due to the direct connection between carbon nanofillers. The PVDF‐HFP/Tuball composite particularly contributed low dielectric loss to the electromagnetic (EM) wave, resulting in excellent microwave absorption properties with a SE per unit thickness of 337.5 dB/mm and 2.5× less weight compared with conventional aluminum with the same SE, demonstrating the promise of using these materials as practical EMI shields.

Authors: Li Wenkai , Zeng Haodong , Xie Zhiyong 
Published: November 2024

ABSTRACTBipolar plates are an essential part of proton exchange membrane fuel cells, and due to the specificity of their functions, various properties are required. In this study, a composite bipolar plate with a “sandwich” structure was prepared to solve the problems of graphite/resin composite bipolar plate, which is challenging in balancing the electrical conductivity and mechanical properties, and the interface is not tightly bonded. Through the bidirectional modification between graphite‐carbon/nanotubes and resin, the graphite phase and resin phase are connected by chemical bonding, which enhances the direct interfacial bonding performance, effectively broadens the conductive pathway, and improves the mechanical properties. The prepared composite bipolar plate showed a conductivity of 244.01 S/cm, a hydrophobicity angle of 121.4°, a flexural strength of 53.38 MPa, a corrosion current density of 0.76 μA/cm2, and a corrosion voltage density of 0.354 V. The composite bipolar plate showed good performance, and it is expected to be one of the candidates for future graphite/resin composite bipolar plate materials.

ABSTRACTIn this study, 5, 10, and 15 wt% colemanite (Ca2B6O11‐5H2O) and 15 wt% Bi2O3 filled high‐density polyethylene (HDPE) composites were fabricated by conventional melt extrusion processing techniques in the form of a layered structure to absorb both neutron radiation and secondary radiation resulting from neutron‐induced reactions. In the layered structure, HDPE was used to slow down neutrons, while colemanite and Bi2O3 were used to trap thermal neutrons and secondary gamma radiation respectively. The properties of the colemanite/HDPE and Bi2O3/HDPE composites were investigated by scanning electron microscopy (SEM), x‐ray diffraction (XRD), and thermogravimetric analysis (TGA). The mechanical properties (tensile and hardness) of the composites were also investigated. The results showed that the addition of colemanite and Bi2O3 particles did not significantly alter the thermal and mechanical properties of the HDPE composites. The total macroscopic cross‐section of the composites was determined using a 239Pu‐Be (α,n) neutron source, while their linear and mass attenuation coefficients were determined using a 137Cs gamma‐ray source. The material with the best neutron absorption rate is 15 wt% colemanite‐filled HDPE (2.31 ± 003 cm−1), while the best gamma‐absorbing material is 15 wt% Bi2O3 filled HDPE (0.114 cm−1). The 15 wt% colemanite, 15 wt% Bi2O3 doped HDPE layered structure has 1.72 ± 0.05 cm−1 macroscopic cross‐sections and 0.098 linear attenuation coefficient. The results show that filled colemanite HDPE composites improve neutron shielding properties and Bi2O3 filled HDPE composites provide good shielding performance for gamma rays.

ABSTRACTObjectiveIron and other biologically important metals are essential to mitochondrial function but are not routinely evaluated. Their equilibrium is critical to the optimal performance of cells with high metabolic activity such as neurons, cardiomyocytes, and skeletal myocytes. Teenagers are at a high risk of iron deficiency even without anemia. Metal ion imbalances can cause cognitive impairments, muscle weakness, and sudden cardiac death. We aim to assess the current prevalence of iron deficiency among collegiate athletes in the Upper Midwest.MethodsOur study is a multicenter, retrospective chart review of outpatient clinics in a regional healthcare system between January 2012 and December 2023, and a national public database between 2017 and March 2020. We reviewed the ferritin concentrations of regional collegiate athletes having preparticipation sport evaluations and nationally in the NHANES database.ResultsWe identified 643 unique individuals aged 16–21 years with 253 having ferritin screening. Iron deficiency (ferritin <20 mcg/L) was present in 24.5% and hypoferritinemia (ferritin <50 mcg/L) was present in 66.7% of collegiate athletes. From the NHANES database, 12.7% of active sampled participants aged 16–21 years were iron deficient.ConclusionOur study findings suggest the need for universal screening for iron deficiency among collegiate athletes given the high prevalence of iron deficiency in both the retrospective chart review and NHANES database analysis. Given the critical role of metal ion homeostasis to optimal mitochondrial function, these findings may warrant the inclusion of ferritin testing in cardiac, neurological, and skeletal muscle evaluations.

Published: November 2024

AbstractCurrently, plastic waste, limited water resources, and water contamination are challenges of universal concerns. Recycling plastic waste as a membrane for water/wastewater treatment is of great significance from the perspective of environmental protection and safe drinking water supply. In this study, we used for the first time the puffed polystyrene beads waste (PPSBW) as a basic material for the fabrication of an ultrafiltration membrane and Pluronic F127 (PF127) as a plasticizer and hydrophilizing agent. Different ratios of PF127 were added to the casting solution, and the characteristics of the blank PPSBW and PF127‐modified membranes (PPSBW‐PF127) were evaluated in detail. The addition of PF127 increased the turbidity and viscosity of the casting solution, decreased the contact angle (increased the hydrophilicity), decreased the pure water flux, and increased the rejection of humic acid. The PPSBW membrane with 3 wt.% of PF127 showed the highest antifouling properties, the highest cleaning efficiency, and kept a satisfactory BSA and pure water flux for 4 runs. Overall, PF127 improved the hydrophilicity, organic matter separation, and enhanced the antifouling properties of the PPSBW‐derived membrane.Highlights
