Authors: Jahangiri Sasan , Poursattar Marjani Ahmad , Kafi‐Ahmadi Leila 
Published: December 2024

ABSTRACTThis study focuses on the synthesis and characterization of Mn₂Sb₂O₇ and MnSb₂O₆ nanocatalysts, which were analyzed using Fourier transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD), Brunauer‐Emmet‐Teller (BET) analysis, scanning electron microscopy with energy dispersive X‐ray (SEM‐EDS), and transmission electron microscopy (TEM). The results confirm that the catalysts have similar chemical compositions and structures, with small amounts of vanadium (V) or iron (Fe) dopants evenly distributed throughout the material. These nanocatalysts demonstrated high efficiency in the one‐pot synthesis of 2‐amino‐4H‐chromenes from malononitrile, dimedone, and aryl aldehydes, achieving yields of 66–90% under optimal conditions using 10 mg of catalyst in ethanol at room temperature. Due to their amphoteric nature, the catalysts enable reactions via acid‐mediated or base‐mediated Hann‐Lapworth mechanisms. Under optimal conditions, the catalysts exhibited turnover numbers (TON) ranging from 1.8 to 3.6 and turnover frequencies (TOF) between 0.0005 and 0.0009 s⁻¹. Moreover, the catalysts can be recovered and reused without losing activity, making them valuable for sustainable chemical synthesis applications.

ABSTRACTSubstituted hydrazones and dihydrazones, as polydenatate ligand, reported high coordination chemical behavior towards numerous transition metals of different oxidation states for alternated applicable interest. Therefore, with a facile condensed reaction of the salicylaldehyde with tartric dihydrazide, a chelated tartrato‐dihydrazone ligand (H2Ltz) was formed. The coordinated features of H2Ltz versus two divalent metal ions of Cu (II) and Ni (II) ions were assumed to form two new bimetallic‐organic framework complexes, assigning triagonal bipyramidal and tetrahedral geometries (CuLtz and NiLtz, respectively). Their structural elucidating was determined within the analytical tools spectroscopically. The effectiveness of the growth inhibition for H2Ltz, CuLtz, and NiLtz against six named bacterial and fungal series, and three human cancer cell lines were examined discovering the reactive role of two central M (II) ions in CuLtz and NiLtz, respectively. The binding character of H2Ltz, CuLtz, and NiLtz, with calf thymus DNA, that is, DNA, was estimated based on the variation in viscometric/spectrophotometric features. The two bimetallic‐chelates represented more distinguished inhibitive attitudes than the regarded one of H2Ltz assigning to the inhibitive zones (mm) and the half‐inhibited concentration (IC50, μM) of growth inhibition of the studied microbes and human tumor cells, respectively. The examination of the binding action of H2Ltz, CuLtz, and CuLtz with DNA was approved according to the enhanced viscosity and the electronic spectral changes. Also, binding constants (14.09, 15.09, and 16.12 107 mol−1 dm3), Gibb's free energy (−42.06, −45.23, and −46.41 kJ mol−1), and the chromism (mainly hypo modes) are assigned to estimate the binding modes. Rewardingly, the bimetallic‐chelates MLtz displayed modified binding action more than that of H2Ltz against DNA regarding their hydrophobicity/lipophilicity.

ABSTRACTBenzophenone is a versatile molecular scaffold that has been extensively explored in medicinal chemistry because of its propensity to exhibit a wide range of biological activities. This study represents a new azide (5) and triazole (6) compounds that were synthesized and well characterized by using FTIR, 1H and 13C NMR spectroscopy and mass spectrometry. UV‐vis and fluorescence spectroscopic studies identified the sensitivity of compound 6 towards Fe(III) with no substantial interference from other metal ions. LOD values for recognition of Fe(III) were found to be 7.94 × 10−5 and 3.67 × 10−7 M, respectively. The biological studies of the compounds (5 and 6) depicted the antibacterial activity against Bacillus subtilis, Staphylococcus aureus and Pseudomonas aeruginosa with the minimum inhibitory concentration range of antibiotics 0.12–6.2 mg/mL. Molecular docking experiments with various bacterial proteins demonstrated that compounds 5 and 6 possessed very low binding energies of −10.39 and −9.14 kcal mol−1 respectively. Both the compounds showed excellent cytotoxic activities against HeLa cells (cervical cell line). Further, the antioxidant quality of compound 6 has been analysed.
Transferability of the Surgical Attire Guideline Adherence Decision‐Making Theory Beyond New England
Authors: Mayes Carole G. , Adams Joanne 
Published: December 2024

ABSTRACTThe AORN surgical attire guideline promotes cleanliness in the perioperative environment to minimize patients’ risks of developing surgical site infections. In 2020, the surgical attire guideline adherence decision‐making model was published based on findings from a study involving New England intraoperative team members. To explore the model's transferability across the United States, we replicated the 2020 study with intraoperative personnel who did not live or work in New England. The study results included the same core category as the 2020 study (ie, critical thinking), and we confirmed that intraoperative team members across the United States weigh the influence of various factors when deciding to what extent they would adhere to the surgical attire guideline. The results showed transferability of the theoretical model to perioperative settings across the United States. This model can be used to enhance intraoperative team members’ surgical attire guideline adherence decisions.
Enhancing the Performance of Lignin/Acrylonitrile Butadiene Hybrid Materials Using Dicarboxylic Acids
Authors: Ghosh Arun 
Published: December 2024

ABSTRACTTo reduce our dependency on petrochemical feedstock, there is a growing interest in utilizing natural biomass to manufacture high‐performance and eco‐friendly materials. Forest‐derived woody biomass contains approximately 20% to 35% lignin by mass, which is mostly underutilized. In the present investigation, lignin feedstock, isolated from the hybrid poplar tree using an n‐butanol‐based solvent mixture, was compounded with acrylonitrile butadiene or nitrile rubber (NBR) at an equal mass ratio to produce hybrid materials under high shear mixing using IntelliTorque Plasticorder. The lignin/NBR blends were modified with several organic acids such as oxalic and malonic acids (0.01 mol of acid/30 g of polymer). The properties such as processing behavior, tensile stress–strain, solvent swelling, melt rheological, and thermal stability of the materials were analyzed. The studies showed that oxalic acid was an effective modifier or cross‐linker, which profoundly increased the thermomechanical properties of the materials. For example, the average tensile strength and modulus of the 50/50 blend of lignin/NBR were 10.9 and 11.8 MPa, respectively, which increased to 15.1 and 396 MPa, respectively, on treatment with oxalic acid. In brief, the mechanical performance revealed that these lignin‐based materials may have potential applications in several areas including building construction and auto‐part manufacturing.

Published: December 2024

ABSTRACTIn this study, we successfully prepared a composite hydrogel that integrates the superior conductivity of carbon nanotubes (CNTs) with the elasticity of hydrogels. This was achieved by depositing a layer of hydroxylated CNTs onto a polyacrylamide (PAM) hydrogel. The PAM hydrogel was immersed in a CNT dispersion at 50°C and subjected to ultrasonic treatment for 30 min, followed by a 50% dehydration process to achieve densification. This process enabled the adsorption of CNTs onto the PAM hydrogel surface, forming robust physical entanglements and hydrogen bonds with the PAM polymer chains. Consequently, this significantly strengthened the interfacial adhesion between the CNTs and the hydrogel, yielding a more durable and resilient composite material. Impressively, the adhesion strength between the CNT layer and the PAM‐CNT composite hydrogel surface reached a remarkable 61.75 J/m2, contributing to its good electrical conductivity (1.284 ± 0.034 S/m), stability, and mechanical properties. Additionally, our study explores the application of the composite material in wearable devices by quantifying its response to pressure, bending, and stretching through resistance change measurements. The findings indicate that this research introduces a new method for preparing conductive hydrogels and offers valuable insights for their use in electronics, biomedicine, and various other related domains.

Published: December 2024

ABSTRACTRural transformation is critical for supporting inclusive economic development. This study assessed the effect of infrastructure and education on the process of rural transformation in Bangladesh using data from four waves of Household Income and Expenditure Surveys between 2000 and 2016. This study employed the Fixed Effects Model, Moment‐Quantile Regression with Fixed Effects Model, and Feasible Generalised Least Squares for checking robustness. The results show that infrastructure and education positively affect rural transformation. The expansion of small‐scale farms, improved healthcare accessibility, and land rental arrangements are key factors that facilitate transformation, whereas the rise of large‐scale farming has a negative impact. Policy recommendations highlight investment in infrastructure and educational access, such as universal primary education, to enhance transformation. It also suggests encouraging land rentals, improving healthcare services, and supporting small‐scale farming while addressing the drawbacks of large‐scale farming to strengthen economic convergence between rural and urban areas.
Occupational therapy‐based rehabilitation of sciatic nerve pain
Authors: Thakur Sudha , Kumar Anoop , Dijkstra Anne , Thakur Abhimanyu 
Published: December 2024

AbstractSciatica is a severe form of pain caused by compression of the sciatic nerve that radiates from the back toward the hip and outer side of the leg. Conventional treatments for sciatica include pain medication, physical therapy, and surgery in severe cases. However, these approaches can be invasive and costly and may not provide long‐term relief. Occupational therapy refers to the intentional and strategic application of various activities associated with daily life, work, education, and leisure to address functional impairments. Focusing on targeted exercises, manual techniques, and ergonomic modifications to alleviate symptoms and improve function, it offers a promising alternative to medical treatments. Occupational therapy interventions for sciatica can reduce pain, increase mobility, and enhance the overall quality of life. As an empowering approach, such techniques aid symptom management and functional independence. This article explores occupational therapy‐based assessments, interventions, outcomes, progress tracking, pharmacotherapy, challenges owing to surgical approaches, and devices for sciatic pain rehabilitation, with assessments aimed at improving the overall quality of life for individuals affected by this condition. Future research should focus on developing and validating new assessment tools and outcome measures specific to sciatica, enabling more accurate evaluation and progress monitoring.

Published: December 2024

ABSTRACTThis study examines the impact of executive compensation (EC) and board sustainability integration index (BSII) on both greenhouse gas emissions (GHGE) and greenhouse gas management processes (GGMP). Additionally, it investigates the relationship between GGMP and GHGE to assess the effectiveness of process‐oriented measures in reducing actual emissions. Through the lens of legitimacy theory and incentive alignment theory, we harness an extensive dataset encompassing 15,876 firm‐year observations across 22 industrialised European countries from 2002 to 2022. First, the findings show that although EC positively correlates with enhanced GGMP, it has an insignificant effect on GHGE reduction. Second, the results suggest that although BSII independently bolster sustainability initiatives, the moderating effect of BSII on EC (EC*BSII) may lead to a legitimacy gap. This gap emerges when the relationship of EC and BSII falls short of societal expectations regarding environmental performance, potentially eroding organisational legitimacy. Third, the findings indicate that firms that engage in GGMP also tend to have higher levels of GHGE, pointing to the use of GGMP by firms as a means of symbolic legitimation.
Rethinking psychological interventions in autism: Toward a neurodiversity‐affirming approach
Authors: Graf‐Kurtulus Sandra , Gelo Omar C. G. 
Published: December 2024

AbstractBackgroundAutism is characterised by unique patterns of social interaction, communication and repetitive behaviours, often accompanied by comorbid conditions such as mood disorders and anxiety. Standard psychological interventions, such as applied behaviour analysis (ABA) and social skill training (SST), are commonly used but remain controversial due to their focus on aligning autistic individuals with societal norms.AimsThis paper critically evaluates standard approaches targeting core autistic traits and explores the therapeutic potential of prioritising comorbidities coherently with neurodiversity‐affirming strategies.Materials and MethodsA critical analysis of clinical and empirical literature was conducted to evaluate the efficacy, ethical issues and broader implications of interventions such as ABA and SST. Particular emphasis was placed on synthesising findings relevant to mental health outcomes, autistic identity formation and the potential of neurodiversity‐affirming interventions to reduce distress and promote well‐being.ResultsStandard approaches often contribute to adverse effects, such as social camouflaging and increased mental health challenges. Conversely, interventions addressing comorbid conditions such as depression and anxiety, combined with neurodiversity‐affirming strategies that support autistic identity and adapt the environment, demonstrate improved mental health outcomes and greater self‐acceptance.DiscussionWe highlight the importance of shifting the therapeutic focus from modifying core autistic traits to addressing comorbidities while fostering a coherent autistic identity. Such a dual approach aligns with the neurodiversity paradigm and emphasises the need for interventions that enhance well‐being by reducing distress caused by comorbid conditions without suppressing autistic characteristics.ConclusionPrioritising comorbid conditions while fostering autistic identity through neurodiversity‐affirming strategies offers a more ethical and effective approach to improving mental health and self‐acceptance in autistic individuals. This dual approach advocates for therapeutic practices that align with their well‐being and identity.

Published: December 2024

AbstractIn an era where renewable energy resources are pivotal yet plagued by variability, vanadium‐cerium (V‐Ce) redox flow batteries (RFBs) present a sophisticated solution to energy storage and grid stability. This study focuses into the electrochemical integration of cerium with vanadium to enhance traditional redox flow batteries′ energy density and cost‐effectiveness. Through an innovative design that allows scalability and addresses the challenges of the lower energy density inherent in vanadium RFBs, V‐Ce RFBs demonstrate the potential for more compact and efficient energy storage systems. In this work, we provide the open‐source design mono cell for RFBs research. Herein, the research spotlights the electrochemical characterization of Ce‐based electrolytes, employing mixed acid electrolytes to improve solubility. For improving the electrochemical performance of the V‐Ce RFBs including the diffusion coefficients and electron transfer rates, L–Leucine and L–Lysine have been used as organic additives. Obtained results have revealed that these additives not only influence the electrochemical stability and efficiency but also significantly affect to the charge‐discharge properties of the V‐Ce RFBs, in which, the L‐leucine showing superior performance over L‐lysine. These findings propose a new way for optimizing the stability of V‐Ce RFBs for large‐scale energy storage regarding efficiency, safety, and environmental impact.

Published: December 2024

AbstractZinc is an important physiological cation, and its misregulation is implicated in various diseases. It is therefore important to be able to image zinc by non‐invasive methods such as Magnetic Resonance Imaging (MRI). In this work, we have successfully synthesized a novel Gd3+‐based complex specifically for Zn2+ sensing by MRI. Using a combination of NMR, luminescence, potentiometric, and relaxivity experiments, completed with DFT calculations, we demonstrate that incorporating a short linker between the Zn2+ sensing unit and the Gd3+ complex leads to unique behavior of the system in the absence of Zn2+. A significant increase in efficacy of the system is observed upon Zn2+ binding, and importantly, the complex is highly selective for Zn2+ relative to other physiological cations. A comprehensive structural study reliably determines the microscopic parameters at the origin of the Zn2+ response, primarily an increase in the number of water molecules directly coordinated to Gd3+ upon Zn2+ binding. Crucially, the system maintains a strong response to Zn2+ binding in the presence of Human Serum Albumin, highlighting its potential for biological applications.

Published: December 2024

AbstractThe expression of Klebsiella pneumoniae carbapenemase (KPC), a type of carbapenem‐hydrolyzing β‐lactamase, in Gram‐negative bacteria has caused significant bacterial resistance to carbapenems, the antibiotic of last resort. Herein, we describe the discovery of 2‐carboxyquinoline boronic acids as inhibitor of KPC. We have identified fluoro‐substituted carboxyquinoline boronic acids 1 e as the most potent inhibitor, with an IC50 of 8.3 nM for KPC‐2, while this compound is significantly less efficient at reducing the activity of other β‐lactamases. This compound proved to have low cytotoxicity towards mammalian cells, as well as low haemolysis and antibacterial activity. However, 1 e potentiated the efficacy of β‐lactam antibiotics (e. g., meropenem and ceftazidime) against KPC‐2‐expressing resistant Klebsiella pneumonia by up to 256‐fold.

ABSTRACTBackground and ObjectivesScreening of rural women of Assam by careHPV test for high‐risk HPV (hr‐HPV) DNA and Papanicolaou (PAP) test for abnormal cytology.MethodThis prospective cross‐sectional study included 480 non‐pregnant women participants aged 20–70 years from Kamrup District, Assam. Two cervical scrap samples were obtained from eligible enrolled women. The Hr‐HPV DNA test by CareHPV was performed with one cervical scrap, and a second cervical scrap sample was used for the Papanicolaou (PAP) test. The statistical analysis was done using RStudio for variables. A p‐value < 0.05 was considered to be statistically significant.ResultsWomen having positive hr‐HPV DNA outcomes were 3.33% (16/480) and 7.7% (37/480) women had positive PAP. Tobacco chewing was significantly associated with positive hr‐HPV DNA (p = 0.04) and positive PAP (p = 0.03) status. Alcohol‐consuming women have a significantly higher risk of positive hr‐HPV DNA (p < 0.00001) and positive PAP (p‐0.04) outcomes. Irregular menstruation (p = 0.004) and urogenital tract infection (p = 0.008) also have significant risk for a positive hr‐HPV DNA status. The positive hr‐HPV DNA status was also significant in women having > 3 numbers of children birth (p = 0.003).ConclusionWe found that the positive hr‐HPV DNA status among rural women in Kamrup, Assam, was significantly associated with alcohol consumption, tobacco chewing, irregular menstruation, urogenital tract infection, and more than three children birth. The abnormal cytology outcome was also substantially associated with tobacco chewing and alcohol consumption.
