The effect of sarpogrelate compared to aspirin in high- or very-high-risk diabetes for primary prevention.

The benefit of aspirin in primary prevention for atherosclerotic cardiovascular diseases (ASCVD) is questionable due to bleeding complications. We analyzed the Korean National Health Insurance data to compare the efficacy and overall bleeding of sarpogrelate, an antiplatelet agent with lower bleeding risk, versus aspirin in high-/very-high-risk diabetic populations without prior ASCVD. The primary endpoint was net adverse clinical events (NACE), defined as a composite of efficacy and overall bleeding.

A pediatric emergency prediction model using natural language process in the pediatric emergency department.

This study developed a predictive model using deep learning (DL) and natural language processing (NLP) to identify emergency cases in pediatric emergency departments.

Various NLP models, including four machine learning (ML) models with Term Frequency-Inverse Document Frequency (TF-IDF) and two DL models based on the KM-BERT framework, were trained to differentiate emergency cases using clinician transcripts.

Bilayer electrified-membrane with pair-atom tin catalysts for near-complete conversion of low concentration nitrate to dinitrogen.

Discharge of wastewater containing nitrate (NO) disrupts aquatic ecosystems even at low concentrations. However, selective and rapid reduction of NO at low concentration to dinitrogen (N) is technically challenging. Here, we present an electrified membrane (EM) loaded with Sn pair-atom catalysts for highly efficient NO reduction to N in a single-pass electrofiltration.

Single-cell transcriptomics of bronchoalveolar lavage during PRRSV infection with different virulence.

Porcine reproductive and respiratory syndrome virus (PRRSV) causes significant economic losses in the global swine industry due to its high genetic diversity and different virulence levels, which complicate disease management and vaccine development. This study evaluated longitudinal changes in the immune cell composition of bronchoalveolar lavage fluid and the clinical outcomes across PRRSV strains with varying virulence, using techniques including single-cell transcriptomics. In highly virulent infection, faster viral replication results in an earlier peak lung-damage time point, marked by significant interstitial pneumonia, a significant decrease in macrophages, and an influx of lymphocytes.

Internalization of Ionic Transport Ability of Polymer Semiconductors via Photochemical Cross-Linking.

In the field of organic electronics and optics, there is rapidly growing interest in enhancing both charge transport and the ion transport properties of semiconductors, particularly in light of recent emerging technologies such as organic electrochemical transistors (OECTs) and switchable organic nanoantennas. Herein, we propose a universal method for internalizing the ionic transport properties of conventional polymer semiconductors. The incorporation of a tetrafluorophenyl azide-based photochemical cross-linker with a tetraethylene glycol bridge into poly(3-hexylthiophene) (P3HT) significantly enhances the performance and operational stability of ion-gating devices.

Receptor-ligand interactions for optimized endocytosis in targeted therapies.

Receptor-mediated endocytosis plays a crucial role in the success of numerous therapies and remains central to advancing drug development. This process begins with ligand binding to specific receptors, triggering the internalization and intracellular trafficking of receptor-ligand complexes. These complexes are subsequently directed into distinct routes, either toward lysosomal degradation or recycling to the cell surface, with implications for therapeutic outcomes.

Mangiferin Protects Mesenchymal Stem Cells Against DNA Damage and Cellular Aging via SIRT1 Activation.

The protective effects of mangiferin (MAG) against etoposide- and high glucose (HG)-induced DNA damage and aging were investigated in human bone marrow-mesenchymal stem cells (hBM-MSCs). Etoposide, a topoisomerase II inhibitor, was used to induce double-strand breaks (DSBs) in hBM-MSCs, resulting in increased genotoxicity, elevated levels of the DNA damage sensor ATM and CDKN1A, and decreased levels of the aging markers H3 and H4. MAG activated AMPK and SIRT1, thus protecting against DSB-induced damage.

The potential of lazertinib and amivantamab combination therapy as a treatment strategy for uncommon EGFR-mutated NSCLC.

Uncommon epidermal growth factor receptor (EGFR) mutations in non-small cell lung cancer (NSCLC) pose therapeutic challenge due to limited response to EGFR tyrosine kinase inhibitors (TKIs). This study presents preclinical evidence and mechanistic insights into the combination of lazertinib, a third-generation EGFR-TKI; and amivantamab, an EGFR-MET bispecific antibody, for treating NSCLC with uncommon EGFR mutations. The lazertinib-amivantamab combination demonstrates significant antitumor activity in patient-derived models with uncommon EGFR mutations either before treatment or after progressing on EGFR-TKIs.

Spatiotemporal distribution of marine aerosols and gaseous species over the North Pacific Ocean.

Observational studies of marine aerosols are essential for understanding the global aerosol budget and its environmental impacts. This study presents simultaneous in-situ measurements of major ionic components (Cl, NO, SO, NH, K, Ca, Na, and Mg) in aerosols and gaseous species (HCl, HNO, HONO, SO, and NH) over the North Pacific Ocean from July 4 to 15 and September 19 to October 3, 2022. Using high temporal resolution instruments aboard the Republic of Korea's icebreaker research vessel Araon, this study aimed to (1) report the spatial and temporal distributions of aerosols and gaseous species, (2) estimate the source contributions of continental anthropogenic pollutants, and (3) assess the influence of aerosol chemical composition and gaseous species on aerosol acidity and water content.

Improving flood-prone areas mapping using geospatial artificial intelligence (GeoAI): A non-parametric algorithm enhanced by math-based metaheuristic algorithms.

Flooding presents substantial dangers to human lives and infrastructure, underscoring the need to map flood-prone areas to implement effective mitigation measures precisely. Although machine learning algorithms have made great strides, their accuracy in flood susceptibility mapping (FSM) remains limited due to data dependence, interpretability, and explainability issues, overfitting, generalization difficulties, and hyperparameter tuning. This study suggests combining the Decision Tree (DT) algorithm with advanced, math-based metaheuristic optimization algorithms to address these limitations.

Electrolyte reactivity on electrode surfaces for active species formation and Reactive Red X-3B degradation in electrochemical treatment of dyeing wastewater.

The pivotal role of electrolytes such as NaSO and NaCl in electrochemical treatment of dyeing wastewater was investigated by comparing recalcitrant Reactive Red X-3B (RRX-3B) degradation rates, active species formation and intermediates generation in a double-chamber cell. It was found that similar reactive oxygen species (ROS) formed in the anodic chamber are OH and O, in the cathodic chamber is O with different electrolytes, while this is not the case for ROS contribution, RRX-3B degradation kinetic and intermediates. NaCl favored the generation of O, faster decolorization (-N=N- cleavage), and organic intermediates degradation in the anodic chamber.
