An effective early diagnosis is important for rheumatoid arthritis (RA) management. This study reveals a novel RA detection method using bacteriorhodopsin as a photoelectric transducer, a light-driven proton pump in purple membranes (PMs). It was devised by covalently conjugating a PM monolayer-coated electrode with a citrullinated-inter-alpha-trypsin inhibitor heavy chain 3 (ITIH3)542–556 peptide that recognizes the serum RA-associated autoantibodies. The direct serum coating decreased the photocurrents in the biosensor, with the reduction in the photocurrent caused by coating with an RA-patient serum that is significantly larger than that with a healthy-control serum (38.1% vs. 20.2%). The difference in the reduction in the photocurrent between those two serum groups widened after the serum-coated biosensor was further labeled with gold nanoparticle (AuNP)-conjugated anti-IgA (anti-IgA-AuNP) (53.6% vs. 30.6%). Both atomic force microscopic (AFM) and Raman analyses confirmed the sequential peptide, serum, and anti-IgA-AuNP coatings on the PM-coated substrates. The reductions in the photocurrent measured in both the serum and anti-IgA-AuNPs coating steps correlated well with the results using commercial enzyme-linked immunosorbent assay kits (Spearman rho = 0.805 and 0.787, respectively), with both a sensitivity and specificity close to 100% in both steps. It was shown that an RA diagnosis can be performed in either a single- or two-step mode using the developed biosensor. © 2023 by the authors.

The nitrogen reduction reaction (NRR) is essential for sustainable ammonia synthesis but suffers from low selectivity and sluggish kinetics due to hydrogen evolution. Piezocatalysis offers a promising alternative by leveraging strain-induced polarization to enhance reaction specificity and efficiency. We develop a sulfur vacancy-engineered cadmium sulfide (CdS) piezoelectric catalytic system to optimize nitrogen activation. Sulfur vacancies improve nitrogen adsorption, enhance charge separation, and lower the hydrogenation energy barrier, overcoming limitations of traditional electrocatalysts. Through a systematic investigation of charge separation mechanisms, combining theoretical calculations and experimental validation, we demonstrate the crucial role of sulfur vacancies and surface morphology in optimizing catalytic performance. Finite element method (FEM) simulations reveal that the pyramid-like CdS surface generates a strong piezopotential under mechanical stress, enhancing charge transfer and redox reactions. density functional theory (dFT) calculations show sulfur vacancies increase electron availability near the Fermi level, facilitating dinitrogen activation and stabilizing intermediates. Therefore, the optimized CdS catalyst achieves an ammonia production rate of 1702 µg g −1 h −1 —four times higher than pristine CdS—demonstrating the effectiveness of defect engineering in piezoelectric catalysis. This study highlights the synergy between piezoelectric activation and defect engineering, offering insights into charge separation and advancing piezoelectric catalysis for sustainable ammonia synthesis.

BACKGROUNd ANd PURPOSE:Acute respiratory distress syndrome (ARdS) is a catastrophic pulmonary inflammatory dysfunction with a high mortality rate. An overwhelming immune response by neutrophils is a key feature in infective or sterile ARdS. The formyl peptide receptor 1 (FPR1) is a crucial damage-sensing receptor for inflammatory reactions in the initiation and progression of neutrophil-mediated ARdS. However, effective targets for controlling dysregulated neutrophilic inflammatory injuries in ARdS are limited. EXPERIMENTAL APPROACH:Human neutrophils were used to explore the anti-inflammatory effects of cyclic lipopeptide anteiso-C13-surfactin (IA-1) from marine Bacillus amyloliquefaciens. The lipopolysaccharide-induced model of ARdS in mice was used to determine the therapeutic potential of IA-1 in ARdS. Lung tissues were harvested for histology analyses. KEY RESULTS:The lipopeptide IA-1 inhibited immune responses of neutrophils, including respiratory burst, degranulation, and expression of adhesion molecules. IA-1 inhibited the binding of N-formyl peptides to FPR1 in human neutrophils and in hFPR1-transfected HEK293 cells. We identified IA-1 as a competitive FPR1 antagonist, thus diminishing the downstream signalling pathways involving calcium, mitogen-activated protein kinases and Akt. Furthermore, IA-1 ameliorated the inflammatory damage to lung tissue, by decreasing neutrophil infiltration, reducing elastase release and oxidative stress in endotoxemic mice. CONCLUSION ANd IMPLICATIONS:The lipopeptide IA-1 could serve as a therapeutic option for ARdS by inhibiting FPR1-mediated neutrophilic injury.

This study aimed to integrate magnetic resonance imaging (MRI) and related somatosensory evoked potential (SSEP) features to assist in the diagnosis of spinal cord compression (SCC). MRI scans were graded from 0 to 3 according to the changes in the subarachnoid space and scan signals to confirm differences in SCC levels. The amplitude, latency, and time–frequency analysis (TFA) power of preoperative SSEP features were extracted and the changes were used as standard judgments to detect neurological function changes. Then the patient distribution was quantified according to the SSEP feature changes under the same and different MRI compression grades. Significant differences were found in the amplitude and TFA power between MRI grades. We estimated three degrees of amplitude anomalies and power loss under each MRI grade and found the presence or absence of power loss occurs after abnormal changes in amplitude only. For SCC, few integrated approach combines the advantages of both MRI and evoked potentials. However, integrating the amplitude and TFA power changes of SSEP features with MRI grading can help in the diagnosis and speculate progression of SCC. © 2023, The Author(s).

Industrial wastewater pollution harms ecosystems and hinders sustainable development growth. Particularly, hydroquinone (HQ) has transitioned from a commercial chemical to an environmental hazard because of its extensive use in beauty products, pharmaceuticals, chemicals, and food industries. Therefore, developing electrochemical sensors for the detection of HQ is very important for environmental safety. Herein, the 7-ACA monomer was electropolymerized on the glassy carbon electrode (GCE) surface to examine the electrochemical oxidation of HQ utilizing CV (cyclic voltammetry) and dPV (differential pulse voltammetry) techniques. Scanning electron microscopy (SEM) characterization verified the deposition of the p-7-ACA on the glassy carbon electrode (GCE) surface. The designed p-7-ACA@GCE sensor exhibited better electrocatalytic properties. The acquired dPV observations for the p-7-ACA@GCE demonstrated excellent limit of detection (LOd) 8.86 nmol L−1 and broad linear range (0.33 μM to 955 μM) for the detection of HQ. The developed sensor exhibits excellent repeatability, reproducibility, selectivity and better cyclic stability. In addition, the fabricated p-7-ACA@GCE was used to determine the HQ in a different environmental water sample. © 2025

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and influenza A virus infect the respiratory tract through surface proteins, causing similar symptoms. Since the onset of the COVId-19 pandemic, both viruses have posed significant ongoing global health threats. Like the influenza virus, SARS-CoV-2 evolves into variants that can reduce vaccine efficacy. Thus, herbal medicines are being explored as supplementary options to enhance protection against these infections. This study aimed to investigate the therapeutic potential of chlorogenic acid (3-CQA) and related extracts from green coffee beans and Echinacea purpurea against SARS-CoV-2 variants and H1N1 infection. The methods employed included an ELISA-based trimeric spike protein binding assay, viral infection assays, plaque assays, and molecular docking studies. Results showed that 3-CQA blocked spike protein/angiotensin converting enzyme 2 (ACE2) binding for most SARS-CoV-2 variants of concern, except the delta variant. Extracts from Green coffee bean and E. purpurea effectively blocked all variants tested. Additionally, antibodies blocked spike protein binding up to Omicron BA.2. Molecular docking suggested that 3-CQA binding to Omicron BA.1, BA.2, and BA.4, though not to the delta spike protein, may lead to steric hindrance, preventing receptor-binding domain interactions with ACE2. Finally, both 3-CQA and E. purpurea extract showed preventive effects against H1N1 viral infection, though with lower potency compared to SARS-CoV-2. In conclusion, 3-CQA has potential as a phytoconstituent marker for herbs with bioactive properties against SARS-CoV-2 and H1N1 viral infections. © 2024 Center for Food and Biomolecules, National Taiwan University

Pathway analysis, including nontopology-based (non-TB) and topology-based (TB) methods, is widely used to interpret the biological phenomena underlying differences in expression data between two phenotypes. By considering dependencies and interactions between genes, TB methods usually perform better than non-TB methods in identifying pathways that include closely relevant or directly causative genes for a given phenotype. However, most TB methods may be limited by incomplete pathway data used as the reference network or by difficulties in selecting appropriate reference networks for different research topics. Here, we propose a gene set correlation enrichment analysis method, Gscore, based on an expression dataset-derived coexpression network to examine whether a differentially expressed gene (dEG) list (or each of its dEGs) is associated with a known gene set. Gscore is better able to identify target pathways in 89 human disease expression datasets than eight other state-of-the-art methods and offers insight into how disease-wide and pathway-wide associations reflect clinical outcomes. When applied to RNA-seq data from COVId-19-related cells and patient samples, Gscore provided a means for studying how dEGs are implicated in COVId-19-related pathways. In summary, Gscore offers a powerful analytical approach for annotating individual dEGs, dEG lists, and genome-wide expression profiles based on existing biological knowledge. © 2024 Oxford University Press.

In this study, we synthesized an amidoximated polyacrylonitrile nanofiber membrane (P-Oxime). Subsequently, we grafted reactive green 19 (RG19) dye onto its surface, resulting in the formation of the P-Oxime-RG19 membrane. Further enhancement was achieved by physically attaching poly(hexamethylene biguanide) hydrochloride (phMB) to the P-Oxime-RG19 membrane, leading to the formation of the P-Oxime-RG19-phMB membrane. Extensive characterization of the nanofiber membranes was conducted, focusing on crucial physical and mechanical properties such as functional group content, morphology, and thermostability. The optimization of various modification conditions, including initial dye and phMB concentrations, duration, temperature, and nitrile group conversion to oxime concentrations, played a pivotal role in achieving superior antibacterial performance in P-Oxime-RG19-phMB nanofiber membranes. In-depth analyses involved the application of kinetic and equilibrium thermodynamic models to unravel the modification processes of RG19 dye and phMB in the nanofiber membranes. Under the carefully tuned optimal modification conditions, the P-Oxime-RG19-phMB nanofiber membrane exhibited remarkable antibacterial efficacy, achieving nearly 100% disinfection of E. coli . In addition to exploring its antimicrobial capabilities, we thoroughly examined the repeatability and biocompatibility of the nanofiber membranes. The results indicated not only the P-Oxime-RG19-phMB nanofiber membrane was a highly promising antibacterial material but also highlighted its potential for diverse applications, particularly in food and textile fabrication, owing to its exceptional performance and suitability.
