    Almost over ten years, environmental experts have concentrated on implementing risk-based management strategies for the remediation of sites contaminated with total petroleum hydrocarbons (TPHs), which can potentially have detrimental ecological impacts. Phytoremediation widely recognized as a green technology a plant-based and economically efficient technology, emerges as a promising method to offer an alternative to existing treatment technologies in TPH contaminated ecosystems. The utilization of Scirpus grossus, a perennial plant, has been proposed as a practical, safe, and cost-effective method for remediating soil contaminated with petroleum hydrocarbons. This study aimed to evaluate the efficacy of S. grossus in removing total petroleum hydrocarbons (TPH) in real crude-oil sludge. Employing a batch phytoremediation system with S. grossus, the experiment was conducted in crates within a greenhouse, maintaining ambient temperatures (30 °C-35 °C) for a duration of 28 days. Each crate was populated with 9-month-old plants of uniform size, initially cultivated in the greenhouse before being transplanted into crates containing 100 % crude-oil sludge with an initial TPH concentration of 37,554 mg/kg for the treatment phase. TPH removal rates were assessed after 14, 21, and 28 days of exposure, resulting in removal rates of 67 %, 74 %, and 75 %, respectively. The highest concentration of rhizobacteria recorded in both sample (with contaminants and without contaminants) were 5.56 × 104 and 5.72 × 104 CFU/mL respectively. Furthermore, TPH extraction from both stems and roots of S. grossus was analysed, revealing the highest TPH concentration of 15,319 mg/kg and about 8000 mg/kg of TPH at day 28 by roots and stem sample respectively. In conclusion, S. grossus demonstrated substantial potential in effectively mitigating the toxicity of TPH in real crude-oil sludge contamination scenarios.

    Inhalation of particulate matter (PM), one of the many components of air pollution, is associated with the development and exacerbation of chronic respiratory diseases, such as chronic obstructive pulmonary disease (COPD). COPD is one of the leading causes of global mortality and morbidity, with a paucity of therapeutic options and a significant contributor to global health expenditure. This review aims to provide a mechanistic understanding of the cellular and molecular pathways that lead to the development of COPD following chronic PM exposure. Our review describes how the inhalation of PM can lead to lung parenchymal destruction and cellular senescence due to chronic pulmonary inflammation and oxidative stress. Following inhalation of PM, significant increases in a range of pro-inflammatory cytokines, mediated by the nuclear factor kappa B pathway are reported. This review also highlights how the inhalation of PM can lead to deleterious chronic oxidative stress persisting in the lung post-exposure. Furthermore, our work summarises how PM inhalation can lead to airway remodelling, with increases in pro-fibrotic cytokines and collagen deposition, typical of COPD. This paper also accentuates the interconnection and possible synergism between the pathophysiological mechanisms leading to COPD. Our work emphasises the serious health consequences of PM exposure on respiratory health. Elucidation of the cellular and molecular mechanisms can provide insight into possible therapeutic options. Finally, this review should serve as a stark reminder of the need for genuine action on air pollution to decrease the associated health burden on our growing global population.

    Previous evidence suggests males and females differ with respect to interoception-the processing of internal bodily signals-with males typically outperforming females on tasks of interoceptive accuracy. However, interpretation of existing evidence in the cardiac domain is hindered by the limitations of existing tools. In this investigation, we pooled data from several samples to examine sex differences in cardiac interoceptive accuracy on the phase adjustment task, a new measure that overcomes several limitations of the existing tools. In a sample of 266 individuals, we observed that females outperformed males, indicative of better cardiac interoceptive accuracy, but had lower confidence than males. These results held after controlling for sex differences in demographic, physiological and engagement factors. Importantly, these results were specific to the measure of cardiac interoceptive accuracy. No sex differences were observed for individuals who completed the structurally identical screener task, although a similar pattern of results was observed in relation to confidence. These surprising data suggest the presence of a female advantage for cardiac interoceptive accuracy and potential differences in interoceptive awareness (metacognition). Possible reasons for mixed results in the literature, as well as implications for theory and future research, are discussed.

    With the widespread use of plastic products, microplastics and nanoplastics have emerged as prevalent pollutants in coastal aquatic ecosystems. Parasesarma pictum, a common estuarine crab species, was selected as a model organism. P. pictum was exposed to polystyrene (PS) particles of sizes 80 nm (80PS), 500 nm (500PS), and 1000 nm (1000PS), as well as to clean seawater (CK) for 21 days. Histological and fluorescent staining results showed that PS particles of all three sizes induced hepatopancreatic nuclear pyknosis, cell junction damage, and necrosis. The degree of damage was observed as 1000PS > 80PS > 500PS. Transcriptomic analysis revealed that major differentially expressed genes (DEGs) were associated with cellular processes, membrane components, and catalytic activity. The respiratory chain disruptions and immune exhaustion induced by 1000PS were notably stronger than those by 80PS and 500PS. Additionally, necrosis caused hepatopancreas injury in P. pictum rather than apoptosis or autophagy after long-term PS particle exposure. Furthermore, PS particles of all three sizes inhibited innate immunity, while the complement pathway was not significantly affected in the 80PS group. This study elucidated potential distinctions in how plastic particles of varying sizes (nanoplastics, microplastics, and micro/nanoplastics) impact P. pictum, providing a reference for toxicological mechanism research on microplastics and nanoplastics in aquatic organisms. Future research should focus on exploring long-term effects and potential mitigation strategies for microplastics and nanoplastics of more types and a wider range of particle size pollution in aquatic environments.

    The relationship between socioeconomic status (SES) and health outcomes has garnered significant attention. However, there is a limited amount of research exploring the association between SES and the risk of metabolic syndrome in Malaysian adults. This study aimed to determine the association between SES and risk of hypertension, diabetes and obesity. By using data from the National Health and Morbidity Survey (NHMS), SES was derived through principal component analysis involving six variables. Two different SES components were identified and labeled as "social status" and "wealth status." Among the participants, 36% were diagnosed with hypertension, 18% with obesity, and 21% with diabetes. Adults with high wealth and social status showed a significantly increased risk of obesity. Meanwhile, high social status was significantly associated with a reduction in the risk of hypertension and diabetes. A comprehensive understanding of the associations between SES and noncommunicable diseases could facilitate initiatives that promote healthy lifestyle behaviors, thereby enhancing the holistic well-being of Malaysians.

    Leptospirosis and enteric fever are prevalent tropical acute bacterial febrile illnesses in Kelantan, Malaysia, that exhibit overlapping features and shared transmission dynamics, yet their spatial relationship remains understudied. This study aimed to analyze their spatial distribution, investigating potential interactions and intersecting patterns. A total of 212 laboratory-confirmed cases of enteric fever and 1106 of leptospirosis between 2016 and 2022, were retrieved from the national e-Notifikasi registry. Point pattern analysis revealed clustering of both diseases in the northern region, but leptospirosis was predominant in the south, exhibiting higher spatial risk. Seven co-infection cases were identified in overlapping hotspot areas. Spatial dependence between the diseases was identified within 4 km distance on average, with varying patterns over time and regions. Recognizing spatial dependence has implications for accurate diagnosis, timely intervention, and tailored public health strategies. The findings underscore the need for multi-disease interventions to address shared risk factors and co-infections in similar geographical contexts.

    INTRODUCTION: Counterfeit medicines are a significant problem globally. In a developing country like Nepal, community pharmacists play an important role in dispensing medicines. The study was done to assess community pharmacists' perceived prevalence, awareness and attitude towards counterfeit medicines in Kathmandu valley.  Methods: A cross-sectional study design was used. Data was collected conveniently from Kathmandu, Bhaktapur, and Lalitpur districts in March 2022 after obtaining ethical clearance from Nepal Health Research Council (reference no. 2200) and taking written informed consent from Community Pharmacists.  Results: Among the 343 pharmacists who participated, 250 (72.89%) were from Kathmandu, 57 (16.62%) were from Lalitpur, and 36 (10.50%) from Bhaktapur. Most 252 (73.47%) were aged between 20 to 30 years, 222 (64.72%) were male, 239 (69.68%) had done a Diploma in Pharmacy, 201 (58.60%) had working experience of more than 5 years and 342 (99.71%) had done their education in Nepal. Their median perceived prevalence of counterfeit drugs was 10.00% but only 2.30% had clear knowledge of such practice. 332 (96.79%) believed that actions should be taken against community pharmacists dispensing counterfeit drugs, 325 (94.75%) believed that pharmacists who dispense counterfeit medicines are unprofessional; 338 (98.54%) stated that there should be strong law against counterfeit medicine sales.

    CONCLUSIONS: Median perceived prevalence of counterfeit medicines was 10.00% but only 2.30% were aware of counterfeit medicine dispensing. Out of 343 pharmacists, 332 (96.79%) mentioned that  action should be taken against those pharmacists knowingly dispensing counterfeit medicines and 338 (98.54%) stated that there should be strong law against counterfeit medicines.

    BACKGROUND: Preterm infants who are extubated following a period of invasive ventilation via an endotracheal tube are at risk of developing respiratory failure, leading to reintubation. This may be due to apnoea, respiratory acidosis, or hypoxia. Historically, preterm infants were extubated to head box oxygen or low-flow nasal cannulae. Support with non-invasive pressure might help improve rates of successful extubation in preterm infants by stabilising the upper airway, improving lung function, and reducing apnoea. This is an update of a review first published in 1997 and last updated in 2003.

    OBJECTIVES: To determine whether nasal continuous positive airway pressure (NCPAP), applied immediately after extubation of preterm infants, reduces the incidence of extubation failure and the need for additional ventilatory support, without clinically important adverse events.

    SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, and trial registries on 22 September 2023 using a revised strategy. We searched conference abstracts and the reference lists of included studies and relevant systematic reviews.

    SELECTION CRITERIA: Eligible trials employed random or quasi-random allocation of preterm infants undergoing extubation. Eligible comparisons were NCPAP (delivered by any device and interface) versus head box oxygen, extubation to room air, or any other form of low-pressure supplemental oxygen. We grouped the comparators under the term no continuous positive airway pressure (no CPAP).

    DATA COLLECTION AND ANALYSIS: Two review authors independently assessed the risk of bias and extracted data from the included studies. Where studies were sufficiently similar, we performed a meta-analysis, calculating risk ratios (RRs) with their 95% confidence intervals (CIs) for dichotomous data. For the primary outcomes that showed an effect, we calculated the number needed to treat for an additional beneficial outcome (NNTB). We used the GRADE approach to assess the certainty of the evidence for clinically important outcomes.

    MAIN RESULTS: We included nine trials (with 726 infants) in the quantitative synthesis of this updated review. Eight studies were conducted in high-income countries between 1982 and 2005. One study was conducted in Chile, which was classified as upper-middle income at the time of the study. All studies used head box oxygen in the control arm. Risk of bias was generally low. However, due to the inherent nature of the intervention, no studies incorporated blinding. Consequently, the neonatal intensive care unit staff were aware of the assigned group for each infant, and we judged all studies at high risk of performance bias. However, we assessed blinding of the outcome assessor (detection bias) as low risk for seven studies because they used objective criteria to define both primary outcomes. NCPAP compared with no CPAP may reduce the risk of extubation failure (RR 0.62, 95% CI 0.51 to 0.76; risk difference (RD) -0.17, 95% -0.23 to -0.10; NNTB 6, 95% CI 4 to 10; I2 = 55%; 9 studies, 726 infants; low-certainty evidence) and endotracheal reintubation (RR 0.79, 95% 0.64 to 0.98; RD -0.07, 95% CI -0.14 to -0.01; NNTB 15, 95% CI 8 to 100; I2 = 65%; 9 studies; 726 infants; very low-certainty evidence), though the evidence for endotracheal reintubation is very uncertain. NCPAP compared with no CPAP may have little or no effect on bronchopulmonary dysplasia, but the evidence is very uncertain (RR 0.89, 95% CI 0.47 to 1.68; RD -0.03, 95% CI -0.22 to 0.15; 1 study, 92 infants; very low-certainty evidence). No study reported neurodevelopmental outcomes.

    AUTHORS' CONCLUSIONS: NCPAP may be more effective than no CPAP in preventing extubation failure in preterm infants if applied immediately after extubation from invasive mechanical ventilation. We are uncertain whether it can reduce the risk of reintubation or bronchopulmonary dysplasia. We have no information on long-term neurodevelopmental outcomes. Although there is only low-certainty evidence for the effectiveness of NCPAP immediately after extubation in preterm infants, we consider there is no need for further research on this intervention, which has become standard practice.

    Lung inflammation involves the activation of immune cells and inflammatory mediators in response to injury and infection. When inflammation persists, fibroblasts, which are resident lung cells, become activated, leading to pulmonary fibrosis (PF), abnormal wound healing, and long-term damage to the alveolar epithelium. This persistent inflammation and fibrosis can also elevate the risk of lung cancer, emphasizing the need for innovative treatments. Current therapies, such as inhaled corticosteroids (ICS) and chemotherapy, have significant limitations. Although conventional nanoparticles (NPs) provide a promising avenue for treating lung disorders, they have limited selectivity and stability. Polyethylene glycol (PEG) grafting can prevent NP aggregation and phagocytosis, thus prolonging their circulation time. When combined with targeting ligands, PEGylated NPs can deliver drugs precisely to specific cells or tissues. Moreover, pH-sensitive NPs offer the advantage of selective drug delivery to inflammatory or tumor-acidic environments, reducing side effects. These NPs can change their size, shape, or surface charge in response to pH variations, improving drug delivery efficiency. This review examines the techniques of PEGylation, the polymers used in pH-sensitive NPs, and their therapeutic applications for lung inflammation, fibrosis, and cancer. By harnessing innovative NP technologies, researchers can develop effective therapies for respiratory conditions, addressing unmet medical needs and enhancing patient outcomes.

    Malaria continues to pose a significant threat to global health, which is exacerbated by the emergence of drug-resistant strains, necessitating the urgent development of new therapeutic options. Due to their substantial bioactivity in treating malaria, pyridine and pyrimidine have become the focal point of drug research. Hybrids of pyridine and pyrimidine offer a novel and promising avenue for developing effective antimalarial agents. The ability of these hybrids to overcome drug resistance is tinted, offering a potential solution to this critical obstacle in the treatment of malaria. By targeting multiple pathways, these hybrid compounds reduce the likelihood of resistance development, providing a promising strategy for combating drug-resistant strains of malaria. The review focuses on the most recent developments in 2018 in the structural optimization of pyridine and pyrimidine hybrid compounds, highlighting modifications that have been shown to improve antimalarial activity. Structure-activity studies have elucidated the essential characteristics required for potency, selectivity, and pharmacokinetics. Molecular docking and virtual screening expedite the identification of novel compounds with enhanced activity profiles. This analysis could aid in developing the most effective pyridine and pyrimidine hybrids as antimalarial agents.

    BACKGROUND: The COVID-19 pandemic has increased the level of anxiety among Indonesian senior high school teachers, who face challenges to treat their mental disorder symptoms that arise during their working hours, as mental health services in Indonesia are limited. Therefore, it is vital to equip schoolteachers in Indonesia with early interventions that are easily available, private, and affordable, and 1 feasible approach is to deploy a smartphone mobile app.

    OBJECTIVE: The objectives of this study are (1) to evaluate the feasibility of a brief mindfulness-based mobile app (BM-MA) for Indonesian senior high school teachers experiencing anxiety and stress and (2) to examine the effects of using the BM-MA on anxiety, stress, life satisfaction, self-efficacy, trait mindfulness, self-compassion, and physical and social dysfunction among the participants.

    METHODS: We followed the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) 2013 statement for this feasibility randomized controlled trial (RCT) protocol. A total of 60 Indonesian senior high school teachers were recruited for this study and randomly assigned to either the intervention group (BM-MA) or a wait-list control group (CG) in a 1:1 ratio. The BM-MA group was required to engage in mindfulness practices using the app for 10-20 minutes per day for 3 weeks. All participants were assessed with a battery of self-report measures at baseline, postintervention, and at 1-month follow-up. Validated scales used to measure the outcome variables of interest included the Satisfaction With Life Scale (SLS), the Teachers' Sense of Efficacy Scale (TSES), the Self-Compassion Scale-Short Form (SCS-SF), Generalized Anxiety Disorder-7 (GAD-7), General Health Questionnaire-12 (GHQ-12), and the Five Facet Mindfulness Questionnaire (FFMQ). The practicality and acceptability of the app will be evaluated using the Client Satisfaction Questionnaire-8 (CSQ-8) and structured qualitative interviews. Data from the interviews will be analyzed with the deductive thematic analysis framework as a process of qualitative inquiry. Repeated measures ANOVA with groups (intervention vs control) as a between-subject factor and time as a within-subject factor (baseline, postintervention, and 1-month follow-up) will be used to examine the effects of the BM-MA on the outcome variables. The data will be analyzed using an intent-to-treat approach and published in accordance with CONSORT (Consolidated Standards of Reporting Trials) recommendations.

    RESULTS: Participants were recruited in December 2023, and this pilot RCT was conducted from January through March 2024. Data analysis was conducted from March through May 2024. The results of this study are expected to be published in December 2024. The trial registration of this protocol was submitted to the Chinese Clinical Trial Registry.

    CONCLUSIONS: This study aims to determine the feasibility and efficacy of the BM-MA, a digital mental health intervention developed using an existing mindfulness-based app, and assess its potential for widespread use.

    The Extended matching Questions (EMQs), or R-type questions, are format of selected-response. The validity evidence for this format is crucial, but there have been reports of misunderstandings about validity. It is unclear what kinds of evidence should be presented and how to present them to support their educational impact. This review explores the pattern and quality of reporting the sources of validity evidence of EMQs in health professions education, encompassing content, response process, internal structure, relationship to other variables, and consequences. A systematic search in the electronic databases including MEDLINE via PubMed, Scopus, Web of Science, CINAHL, and ERIC was conducted to extract studies that utilize EMQs. The framework for a unitary concept of validity was applied to extract data. A total of 218 titles were initially selected, the final number of titles was 19. The most reported pieces of evidence were the reliability coefficient, followed by the relationship to another variable. Additionally, the adopted definition of validity is mostly the old tripartite concept. This study found that reporting and presenting validity evidence appeared to be deficient. The available evidence can hardly provide a strong validity argument that supports the educational impact of EMQs. This review calls for more work on developing a tool to measure the reporting and presenting validity evidence.

    This review aimed to systematically compare and pool the prevalence of all the known evidence on caregiver hesitancy and to describe the factors influencing vaccine hesitancy among caregiver worldwide such as COVID-19, MMR, Influenza, HPV and others. We searched article from few electronic databases (PubMed, CENTRAL, ProQuest, and Web of Science) from inception to August 2023 using specific keywords for example caregiver, parents, prevalence, factor, hesitancy, and others. We included population-based studies that reported the prevalence of caregiver hesitancy. We used random-effects meta-analyses for pool prevalence estimates of caregiver hesitancy. A total of 765 studies met our inclusion criteria, containing data on 38,210,589 caregivers from seven regions across the globe. Overall or pool prevalence of vaccine hesitancy among caregiver is 25.0% (95% CI: 0.22-0.27, I2 = 99.91%, p = 0.001). Based on the evidence gathered, vaccine hesitancy was found to be religious sentiments, personal beliefs, perceived safety concerns, and a desire for more information from healthcare providers, along with factors related to availability, accessibility, affordability, and acceptability of vaccinations. Vaccine safety and efficiency have been identified as the main factor for caregiver vaccine hesitancy globally with a prevalence of 91.4%.

    The WHO Classification of Tumours (WCT) guides cancer diagnosis, treatment, and research. However, research evidence in pathology continuously changes, and new evidence emerges. Correct assessment of evidence in the WCT 5th edition (WCT-5) and identification of high level of evidence (LOE) studies based on study design are needed to improve future editions. We aimed at producing exploratory evidence maps for WCT-5 Thoracic Tumours, specifically lung and thymus tumors. We extracted citations from WCT-5, and imported and coded them in EPPI-Reviewer. The maps were plotted using EPPI-Mapper. Maps displayed tumor types (columns), descriptors (rows), and LOE (bubbles using a four-color code). We included 1434 studies addressing 51 lung, and 677 studies addressing 25 thymus tumor types from WCT-5 thoracic tumours volume. Overall, 87.7% (n = 1257) and 80.8% (n = 547) references were low, and 4.1% (n = 59) and 2.2% (n = 15) high LOE for lung and thymus tumors, respectively. Invasive non-mucinous adenocarcinoma of the lung (n = 215; 15.0%) and squamous cell carcinoma of the thymus (n = 93; 13.7%) presented the highest number of references. High LOE was observed for colloid adenocarcinoma of the lung (n = 11; 18.2%) and type AB thymoma (n = 4; 1.4%). Tumor descriptors with the highest number of citations were prognosis and prediction (n = 273; 19.0%) for lung, and epidemiology (n = 186; 28.0%) for thymus tumors. LOE was generally low for lung and thymus tumors. This study represents an initial step in the WCT Evidence Gap Map (WCT-EVI-MAP) project for mapping references in WCT-5 for all tumor types to inform future WCT editions.

    G9P[8] has been the predominant rotavirus A (RVA) genotype in Malaysia since the 2000s. However, the overall genetic makeup and evolution of Malaysian G9P[8] strains are still unknown. Therefore, this study aimed to evaluate and characterize the complete genomes of three G9P[8] RVA strains isolated from diarrheic children under five years old in Sabah. Contrary to the classical Wa-like constellation, these strains contained a DS-1-like genotype. Two strains, namely L202 and L234, were genotype G9-P[8]-I1-R1-C1-M1-A1-N1-T1-E2-H1, while one (KN102) was genotype G9-P[8]-I1-R1-C1-M1-A2-N1-T1-E1-H1. Phylogenetic analysis revealed that the NSP4 genes of L202 and L234 strains were closer to that of G9P[8]-E2 strains from Japan, suggesting they might share a common ancestor. The findings from this study provide new insights into the genetic characteristics of circulating G9P[8] strains in Sabah, which are important for rotavirus surveillance and potential vaccine development in the region.

    BACKGROUND: The health care landscape is evolving rapidly due to rising costs, an aging population, and the increasing prevalence of diseases. To address these challenges, the Ministry of Health of Malaysia implemented transformation strategies such as the Casemix system and hospital information system to enhance health care quality, resource allocation, and cost-effectiveness. However, successful implementation relies not just on the technology itself but on the acceptance and engagement of the users involved.

    OBJECTIVE: This study aims to develop and refine items of a quantitative instrument measuring the critical success factors influencing acceptance of Casemix system implementation within the Ministry of Health's Total Hospital Information System (THIS).

    METHODS: A cross-sectional pilot study collected data from medical doctors at a hospital equipped with the THIS in the federal territory of Putrajaya, Malaysia. This pilot study's minimum sample size was 125, achieved through proportionate stratified random sampling. Data were collected using a web-based questionnaire adapted from the human, organization, and technology-fit evaluation framework and the technology acceptance model. The pilot data were analyzed using exploratory factor analysis (EFA), and the Cronbach α assessed internal reliability. Both analyses were conducted in SPSS (version 25.0; IBM Corp).

    RESULTS: This study obtained 106 valid responses, equivalent to an 84.8% (106/125) response rate. The Kaiser-Meyer-Olkin measure of sampling adequacy was 0.859, and the Bartlett test of sphericity yielded statistically significant results (P0.6, leading to the removal of 1 item for the final instrument for the field study. EFA ultimately identified 8 main constructs influencing Casemix implementation within the THIS: system quality, information quality, service quality, organizational characteristics, perceived ease of use, perceived usefulness, intention to use, and acceptance. Internal reliability measured using the Cronbach α ranged from 0.914 to 0.969, demonstrating high reliability.

    CONCLUSIONS: This study provides insights into the complexities of EFA and the distinct dimensions underlying the constructs that influence Casemix system acceptance in the THIS. While the findings align with extensive technology acceptance literature, the results accentuate the necessity for further research to develop a consensus regarding the most critical factors for successful Casemix adoption. The developed instrument is a substantial step toward better understanding the multidimensional challenges of health care system transformations in Malaysia, postulating an underpinning for future fieldwork and broader application across other hospitals.

    Biodiesel production from Calophyllum inophyllum oil in Indonesia produces significant biomass waste, including seed shells. This study explores the conversion of the seed shell of Calophyllum inophyllum into nanocrystalline cellulose (NCC) via consecutive alkalization, bleaching and hydrolysis using various organic acids. Scanning electron microscopy (SEM) analysis showed a reduction in the diameter of cellulose fibers from 21.7 μm to 9.6 μm after alkalinization and bleaching. The hydrolysis process using several organic acids was optimized to produce thermally stable nanocellulose while maintaining its crystallinity. The diameter of the resulting nanofibrous cellulose was 20.53 nm for citric acid, 21.69 nm for maleic acid, and 22.06 nm for formic acid hydrolysis. In particular, lactic acid-derived NCC (NCC-LA) showed the highest crystallinity of 64.22 % with an average diameter of ~13.69 nm. Optimization of hydrolysis parameters using Response Surface Methodology (RSM) suggested 74.79 % crystallinity could be achieved with 6.01 M lactic acid following 3.46 h of hydrolysis at 91.12 °C.

    The integration of flexible sensors into human-machine interfaces (HMIs) is in increasing demand for intuitive and effective manipulation. Traditional glove-based HMIs, constrained by nonconformal rigid structures or the need for bulky batteries, face limitations in continuous operation. Addressing this, we introduce yarn-based bend sensors in our smart glove, which are wirelessly powered and harvest energy from a fully textile 5.8 GHz WiFi-band antenna receiver. These sensors exhibit a gauge factor (GF) of 5.60 for strains ranging from 0 to 10%. They show a consistent performance regardless of the straining frequency when being stretched and released at frequencies between 0.1 and 0.7 Hz. This reliability ensures that the sensor output is solely dependent on the yarn's elongation. Accurately detecting finger-bending movements from 0° to 90° in a virtual environment, the sensors enable enhanced degrees of freedom for human finger interaction. When integrated with advanced machine-learning techniques, the system achieves a classification accuracy of 98.75% for object recognition, demonstrating its potential for precise and accurate HMI. Unlike conventional near-field energy transfer methods that rely on magnetic flux and are limited by power loss over distance, our fully textile design effectively harvests microwave energy, showing no voltage deterioration up to 1 m away. This minimalist microwave-powered smart glove represents a significant advancement, offering a viable and practical solution for developing intuitive and reliable HMIs.
