Hydrogel‐Based Systems in Neuro‐Vascularized Bone Regeneration: A Promising Therapeutic Strategy
Authors: Li Xiaojing , Cui Ya , He Xiaoya , Mao Lixia 
Published: January 2024

AbstractBlood vessels and nerve fibers are distributed throughout the skeletal tissue, which enhance the development and function of each other and have an irreplaceable role in bone formation and remodeling. Despite significant progress in bone tissue engineering, the inadequacy of nerve‐vascular network reconstruction remains a major limitation. This is partly due to the difficulty of integrating and regulating multiple tissue types with artificial materials. Thus, understanding the anatomy and underlying coupling mechanisms of blood vessels and nerve fibers within bone to further develop neuro‐vascularized bone implant biomaterials is an extremely critical aspect in the field of bone regeneration. Hydrogels have good biocompatibility, controllable mechanical characteristics, and osteoconductive and osteoinductive properties, making them important candidates for research related to neuro‐vascularized bone regeneration. This review reports the classification and physicochemical properties of hydrogels, with a focus on the application advantages and status of hydrogels for bone regeneration. The authors also highlight the effect of neurovascular coupling on bone repair and regeneration and the necessity of achieving neuro‐vascularized bone regeneration. Finally, the recent progress and design strategies of hydrogel‐based biomaterials for neuro‐vascularized bone regeneration are discussed.
The conceptualization of enablers and constraints of in‐store buying as part of the affordances flow funnel process through scan and go apps

Published: January 2024

AbstractThis study explores the affordances of “scan and go” apps and their influence on the flow experience of retail customers to provide a unique insight into user–technology interaction. Through a constructivist ethnographic approach, the research examines how users' socially constructed perceptions and interpretations shape these interactions, and it emphasizes the role of the material and social environment. The research innovatively conceptualizes affordances as a flow process; it introduces an affordances flow funnel that encompasses three distinct stages: perceived affordances, actualized affordances, and affordance dichotomy. By following this process, the study improves understanding of user emotions and behaviors that range from apathy to excitement, from gratification to provocation, and from abandonment to absorption. Findings underline the importance of equipping users with support to navigate technological and environmental constraints, thereby ensuring successful affordance actualization. The research contributes to the literature by revealing a new affordance type, namely affordance dichotomy, and offers valuable insights for marketers and developers to enhance user experiences and absorption behavior. Recognizing its focus on scan and go apps within supermarket contexts, the study invites future research to extend this understanding to different contexts and technologies.

Published: January 2024

AbstractAiming to investigate whether a fresh produce e‐tailer should implement the strategy of advance selling considering the behavior of consumers' risk aversion, we build a two‐stage newsvendor decision‐making model and further explore how the advance selling value is affected by factors, such as the freshness‐keeping cost and the effect of demand information updating on reducing demand uncertainty. The results indicate that adopting advance selling strategy benefits the e‐tailer or not depends on consumer risk aversion and the effect of demand information updating on reducing demand uncertainty. The increasing effect of demand information updating on reducing demand uncertainty is conducive to improving the value of advance selling, and the freshness‐keeping cost may increase or decrease the value of advance selling. Besides, adopting the strategy of advance selling may benefit both the e‐tailer and the consumers under certain conditions.

AbstractFormation of hetero‐contacts between particles of different materials in nanoparticle hetero‐aggregates can lead to new functional properties. Improvement of the functional behavior requires a detailed characterization of mixing between the two types of particles, in order to correlate different mixing with the performance of the material. Scanning transmission electron microscopy (STEM) is an option for this task. To obtain statistically relevant results, STEM‐images of many hetero‐aggregates have to be acquired and evaluated. This can be time‐consuming if it is done manually. In the present work, the applicability of convolutional neural networks for the automated analysis of STEM‐images acquired from TiO–WO nanoparticle hetero‐aggregates is investigated. Hetero‐aggregates are obtained in a double flame spray pyrolysis (DFSP) setup, in which a variation of setup parameters is expected to affect the mixing of TiO and WO. Mixing is investigated by a measurement of cluster sizes (the number of connected particles of the same material within an aggregate) and coordination numbers (the number of particle contacts with particles of the same or the different material). Results show that the distribution of measured values is wide for both quantities, rendering it challenging to correlate mixing with parameters varied in the DFSP setup.

AbstractPurposeThe study aimed to determine the anxiety levels of caregivers who performed clean intermittent catheterization (CIC) on their children and the factors affecting them.MethodsThis descriptive study was conducted between January 6, and May 29, 2023 with caregivers of 42 patients who were followed up by the pediatric nephrology outpatient clinic of a university for CIC. The study data were collected using the “Participant Information Form” and the “State and Trait Anxiety Scale.”ResultsAccording to the results, of the children included in the study, 73.8% were female, 64.3% were diagnosed with spina bifida (SB), and 76.2% received CIC applications 4–6 times a day. All the caregivers were mothers, and 76.2% received CIC training from a doctor. However, 78.6% of them found the training insufficient, leading them to rely on self‐experimentation when applying CIC to their own children. None of the caregivers received information or training on the CIC application from nurses, and there were no home visits or telephone counseling provided after the hospital discharge. The mean score for the state anxiety scale among the caregivers was 45.90 ± 10.57, while the mean score for the trait anxiety scale was 46.92 ± 8.43. Significantly higher mean trait anxiety scores were observed among caregivers with chronic diseases who did not receive training on the CIC application (p < 0.05). Additionally, caregivers of children who experienced 3–4 urinary tract infections (UTIs) within the last 3 months also had significantly higher mean trait anxiety scores (p < 0.05). The mean trait anxiety level scores of caregivers of children who had 3–4 UTIs in the last 3 months were significantly higher (p < 0.05).ConclusionsIt was concluded that caregivers' lack of training on CIC implementation, having chronic disease, and having frequent UTIs in their children were effective on anxiety levels.

AbstractWater pollution is growing at an alarming rate, particularly due to the colored wastewater released by the various industries into aquifers and fresh water sources, and in some extreme cases, they have reached the water table. Faisalabad, a city in Pakistan where there is an industrial cluster of textiles dyeing and manufacturers, water table has become undrinkable. The presence of hazardous dyes and chemicals imposes serious health issues on humans, animals, and plants. The treatment of such toxic dye effluents is crucial and could be done by efficient degradation methods such as photocatalysis. The current study presents synthesis of poly(o‐methylaniline)/zinc oxide/reduced graphene oxide nanocomposite (POMA/ZnO/rGO NC) using a chemical oxidative polymerization process and explores its properties as a photocatalyst by demonstrating degradation of three dyes. The composite was characterized using X‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), photoluminescence emission spectroscopy (PL), Brunauer Emmett–Teller analysis (BET), and UV–visible spectroscopy (UV–visible). Further, the photocatalytic activity of POMA/ZnO/rGO NC was evaluated and compared by degrading the direct yellow 12 (DY 12), congo red (CR), and malachite green (MG) dyes in aqueous media under UV irradiation. The results indicated that after 110 min, POMA/ZnO/rGO composite degraded the dyes by 92% (DY 12), 86.1% (CR), and 82.1% (MG), respectively. Moreover, kinetic studies of the photocatalyst were also performed along with reusability test, total organic carbon, chemical oxygen demand, and degradation mechanism.

AbstractIn order to develop a soft composite with high‐performance puncture resistance and self‐healing property property, herein, we introduced Pluronic F127 diacrylate (F127DA) into titania‐based nanocomposite hydrogels (PAMT) and then compounded hydrogel and aramid fabric to form gel‐matrix soft composites (GMSCs). The result shows that, with the addition of 5 wt% TiO2 nanoparticles, the hydrogels exhibited a fracture strain of 3898%, a toughness of 12.23 MJ/m3 and a self‐healing efficiency of 99.45% after healing at 100°C for 12 h, indicating multiple recycling feature. In addition, a series of mechanical tests had shown that the resultant GMSCs exhibited incredible spike puncture resistance and knife puncture resistance, 17.66 times and 13.78 times greater than that of pure fabrics, and could achieve 33.84% spike puncture self‐healing efficiency and 26.62% knife puncture self‐healing efficiency. The synergetic reinforcement mechanism of the hydrogel and fabrics was also analyzed. This study provides a valuable reference for designing a puncture resistant soft composite with rapid self‐healing and repeated recycling.

Published: January 2024

AbstractThe cationic water‐soluble polymers, which are widely used in many areas such as papermaking and separation process, are typically synthesized through polymerization of cationic monomers represented by quaternary ammonium salt. In this work, the polymerization reaction kinetics of three typical quaternary ammonium salt cationic monomers including acryloyl oxygen ethyl trimethyl ammonium chloride (DAC), methyl acryloyl oxygen ethyl trimethyl ammonium chloride (DMC), and methyl acrylamide propyl trimethyl ammonium chloride (MAPTAC) was examined by using the dilatometer method. The results showed that the polymerization rate of all three monomers increased with the increase of initiation temperature, monomer concentration, and initiator concentration. Under the same conditions, the polymerization activity of the three monomers followed the order: DAC > DMC > MAPTAC. The activation energies for the polymerization reaction under the specified conditions were EaDAC = 138.97 kJ/mol, EaDMC = 141.24 kJ/mol, and EaMAPTAC = 226.97 kJ/mol, respectively. The polymerization rate equations were RpDAC = k1[M]4.25[I]0.51, RpDMC = k2[M]3.77[I]0.50, and RpMAPTAC = k3[M]3.30[I]0.49. The polymerization activity of the monomers may be influenced by electronic effects and steric hindrance of the monomer structure. This work has provided a theoretical and experimental foundation for the actual work of structural design and preparation of cationic water‐soluble polymers.

AbstractFormation of stereocomplex crystals (SCs) in enantiomeric poly(L‐lactide) (PLLA) and poly(D‐lactide) (PDLA) blends is an effective way to improve the heat resistance and mechanical performance of polylactide (PLA) products. However, obtaining PLAs with high stereocomplex content is not straightforward as the homocrystal and SCs occur simultaneously and compete with one another. In this work, various amounts of epoxidized soybean oil (SO) or SO at 3%–20% by weight were added to equal amounts of the stereoisomers (PLLA/PDLA; 50/50). From differential scanning calorimetry, it was found that epoxidized SO increased the crystallization temperature, facilitated the SC crystallization, and suppressed the homecrystal formation, whereas SO did not affect the crystallization behavior for the racemic blends. Moreover, epoxidized SO reduced the glass transition temperature, cold crystallization temperature, and melting temperature of the racemic blends. We examined how epoxidized SO affected the crystallization of PLLA/PDLA at cooling rates from 2 to 20°C/min. We discovered that epoxidized SO still encouraged SC crystallization. The activation energy, calculated from Takhor and Kissinger equations, indicated that adding 5 wt% epoxidized SO effectively promoted the crystallization and facilitated the SC formation of the PLLA/PDLA blend.

AbstractTo synthesize colorless superheat‐resistant polyimide films, one of the valid approaches is the incorporation of the asymmetric and warped structures in the main chain. Applying this approach on 5(6)‐amino‐2‐(4‐aminobenzene)benzimidazole (PABZ) and changing its linearity, 6, 5′‐diamine‐2′‐methyl‐1‐methyl‐2‐phenylbenzimidazole (5a) and 6, 3′‐diamine‐2′‐methyl‐1‐methyl‐2‐phenylbenzimidazole (5b) were devised and synthesized successfully, then polymerized with 1,2,4,5‐cyclohexanetetracarboxylic dianhydride (HPMDA). The prepared poly(benzimidazole imide)s (PBIIs) with the rigid main chain and loose packing had the excellent heat‐resistant level (Tg > 400°C) and optical properties (T400 > 80%). Besides, the alterations resulting from various linearities were discussed comprehensively. This research is beneficial to the application of optical field, providing a promising candidate of heat‐resistant colorless materials.

Published: January 2024

AbstractPurposeThe primary objective of this investigation is to evaluate how morphological quality affects the pregnancy outcomes in euploid embryos determined by preimplantation genetic testing for aneuploidies (PGT‐A). Concurrently, as a secondary objective, we aim to identify which specific aspects of morphological evaluation exert the most significant impact on these outcomes.MethodsA retrospective analysis of 451 single euploid embryo transfer cycles at our clinic was conducted. Embryos were evaluated based on the degree of blastocyst expansion, inner cell mass (ICM), trophectoderm (TE) morphology, and the day of blastocyst vitrification. Outcomes between morphologically low‐grade and high‐grade embryos were compared. Additionally, the study analyzed which morphological factors most influenced pregnancy outcomes.ResultsPregnancy outcomes were significantly lower in morphologically low‐grade blastocysts compared to high‐grade ones. Among the morphological evaluations, the ICM assessment was significantly associated with the live birth rate.ConclusionOur study indicates that the morphological quality of euploid embryos, particularly the evaluation of the ICM, plays a crucial role in IVF‐ET success.
Exploring the past to discern the present: The role of historico‐geographical study in differentiating natural river channels from artificial canals
Authors: Das Balai C. 
Published: January 2024

AbstractThe historical background of a watercourse, whether it be a natural river or an artificial canal, holds great importance in understanding hydrological heritage, landscape evolution, planning processes, and making informed predictions for the future. This study focuses on the case study of the Churni River, which has been regarded as an artificial canal in the local literature, history, and geography research papers. The objective of this study is to investigate the authenticity of the claims and explore whether the Churni River is a natural river or an artificially constructed canal. Through an examination of existing literature and the present channel morphology, it becomes apparent that the alleged myths and rumors surrounding the origin of the Churni River, proposing its deliberate construction as a man‐made canal by Maharaja Krishnachandra, lack substantial evidence. Conversely, a more plausible scenario emerges, suggesting that the Maharaja's endeavors were likely focused on rejuvenating the degraded and silt‐laden course of an already existing river. Additionally, no evidence is found to support the claim that the name “Churni” was assigned by Maharaja Krishnachandra, and the alternative name “Kangkana” lacks substantiation as a name for the river. This research contributes to a comprehensive understanding of the historical and geographical context of the Churni River, shedding light on its origin and nature while emphasizing the significance of historical analysis in distinguishing natural river channels from artificial canals and will widen the avenue of future research on river heritage of like situation.
Lessons from a professional learning community: Navigating tensions while moving between theory and practice in teaching chemistry for social justice
Authors: Ribay Kathryn 
Published: January 2024

AbstractMaintaining a commitment to social justice teaching can be especially challenging when navigating the bureaucratic systems and ever‐spiraling responsibilities of the education system. To better understand how social‐justice‐oriented educators navigate these tensions, this paper uses qualitative methods to investigate the social justice problems of practice identified by five chemistry teachers in a year‐long professional learning community. By analyzing the challenges described in their problem‐posing segments, I identify seven major themes that represent key sources of tension and possibility as teachers move from theory to practice in teaching chemistry for social justice. These findings indicate that the practical considerations of day‐to‐day teaching practice create the most salient tensions when moving from theoretical ideas of social justice to a deeply integrated enactment of social justice teaching. Through a deeper analysis of two cases, I demonstrate the effects of discussing problems of practice with a group of teachers who had similar disciplinary backgrounds and ideological stances. These discussions shifted the tensions from potential barriers to areas of possibility in which they were able to enact new ideas within the confines of their context. Taken together, these findings indicate that developing social justice educators requires attention to navigating the practical details of teaching from a social justice lens.
Societal sustainable development and long‐run economic growth: How do we stand?
Authors: Dima Bogdan , Dima Ştefana Maria , Tudor Adriana Tiron 
Published: January 2024

AbstractThe United Nations' 2030 Agenda for Sustainable Development proposes the ambitious goal of an inclusive and sustainable economy. Thus, a realistic assessment of individual countries' possibilities to implement the Sustainable Development Goals might provide helpful insights. We seek to contribute to the existing literature by proposing a working framework for assessing, at the individual country level, the impact of long‐run economic growth on societal sustainable development. The framework is based on composite models from the Structural Equation Modeling‐SEM with a Partial Least Squares Path Modeling (PLS‐PM) estimator. In contrast, societal sustainable development is viewed as emerging from its various dimensions (environmental protection, human development and public health). Based on the analyses of an extended sample of 99 countries, including data for thirty years (from 1990 to 2019), we find that economic growth matters in explaining societal sustainable development, and different countries have benefited unequally from this situation. The key finding reveals that countries aiming to follow the SDGs should recognize their significant disparities and engage in profound structural, institutional, functional and cultural transformations. Thus, a more holistic approach to societal sustainable development is currently needed to enhance government effectiveness as a transmission channel for the impact of growth. In addition, governments need to adjust their economic mechanisms to internalize the costs of environmental degradation and negative externalities for human development and public health.
