Functional anti-inflammatory mesoporous silica nanoplatform for Synergistic and Targeted abdominal aortic aneurysm treatment.

Abdominal aortic aneurysm (AAA) is a chronic inflammation-driven disease characterized by aortic wall destruction and expansion, leading to high morbidity and mortality. However, previous drug treatments for its common risk factors have not achieved favorable results, and the early prevention and treatment is still the main clinical dilemma. Anti-inflammation therapy is a promising therapeutical method targeting its pathogenesis mechanism, but it has not been explored in depth.

Relation of 91 Circulating Inflammatory Proteins to Nonalcoholic Fatty Liver Disease: A Two-Sample Mendelian Randomisation Study.

Increasingly, emerging research evidence has demonstrated that nonalcoholic fatty liver disease (NAFLD) is a disease closely associated with systemic inflammation. However, the specific upstream inflammatory factors engaged in the pathogenesis of NAFLD remain unclear.

Polyamines Protect Porcine Sperm from Lipopolysaccharide-induced Mitochondrial Dysfunction and Apoptosis via Casein Kinase 2 Activation.

Bacterial contamination is an inevitable issue during the processing of semen preservation in pigs. As a prototypical endotoxin from Gram-negative bacteria in semen, lipopolysaccharide (LPS) undermines sperm function during liquid preservation. Spermine and spermidine could protect cells against LPS-induced injury, and the content of spermine and spermidine in seminal plasma is positively correlated with sperm quality.

Identification of cepharanthine as an effective inhibitor of African swine fever virus replication.

African swine fever virus (ASFV) causes highly contagious swine disease, African swine fever (ASF), thereby posing a severe socioeconomic threat to the global pig industry and underscoring that effective antiviral therapies are urgently required. To identify safe and efficient anti-ASFV compounds, a natural compound library was screened by performing an established cell-based ELISA in an ASFV-infected porcine alveolar macrophage (PAM) model. In total, 6 effective anti-ASFV compounds with low cytotoxicity were identified.

Combating tumor PARP inhibitor resistance: Combination treatments, nanotechnology, and other potential strategies.

PARP (poly (ADP-ribose) polymerase) inhibitors (PARPi) have demonstrated significant potential in cancer treatment, particularly in tumors with breast cancer susceptibility gene (BRCA) mutations and other DNA repair deficiencies. However, the development of resistance to PARPi has become a major challenge in their clinical application. The emergence of drug resistance leads to reduced efficacy of the PARPi over time, impacting long-term treatment outcomes and survival rates.

Identification of host proteins that interact with African swine fever virus pE301R.

African swine fever virus (ASFV) infection poses enormous threats and challenges to the global pig industry; however, no effective vaccine is available against ASFV, attributing to the huge viral genome (approximately189 kb) and numerous encoding products (>150 genes) due to the limited understanding on the molecular mechanisms of viral pathogenesis. Elucidating the host-factor/viral-protein interaction network will reveal new targets for developing novel antiviral therapies. Using proteomic analysis, we identified 255 cellular proteins that interact with the ASFV-encoded pE301R protein when transiently expressed in HEK293T cells.

Unraveling the Multifunctional Mechanism of Fluoroethylene Carbonate in Enhancing High-Performance Room-Temperature Sodium-Sulfur Batteries.

Room-temperature sodium-sulfur (RT Na-S) batteries has attracted growing attentions in large-scale energy storage technology, while the serious shuttle effect and interface side reaction limit its practical application. Despite fluoroethylene carbonate (FEC) has been widely used as an electrolyte additive or co-solvent to facilitate the optimization of electrode-electrolyte interphase in RT Na-S batteries, its crucial influence and mechanism have not been clearly understood. Herein, we deeply reveal the two-steps cathode-electrolyte interphase (CEI) formation by using FEC as the exclusive electrolyte solvent.

CelloType: a unified model for segmentation and classification of tissue images.

Cell segmentation and classification are critical tasks in spatial omics data analysis. Here we introduce CelloType, an end-to-end model designed for cell segmentation and classification for image-based spatial omics data. Unlike the traditional two-stage approach of segmentation followed by classification, CelloType adopts a multitask learning strategy that integrates these tasks, simultaneously enhancing the performance of both.

Design towards recyclable micron-sized NaS cathode with self-refinement mechanism.

Sodium sulfide (NaS) as an initial cathode material in room-temperature sodium-sulfur batteries is conducive to get rid of the dependence on Na-metal anode. However, the micron-sized NaS that accords with the practical requirements is obstructed due to poor kinetics and severe shuttle effect. Herein, a subtle strategy is proposed via regulating NaS redeposition behaviours.

Efficacy of different traditional Chinese medicine decoctions in the treatment of ischemic stroke: a network meta-analysis.

Filtering-Assisted Airborne Point Cloud Semantic Segmentation for Transmission Lines.

Point cloud semantic segmentation is crucial for identifying and analyzing transmission lines. Due to the number of point clouds being huge, complex scenes, and unbalanced sample proportion, the mainstream machine learning methods of point cloud segmentation cannot provide high efficiency and accuracy when extending to transmission line scenes. This paper proposes a filter-assisted airborne point cloud semantic segmentation for transmission lines.

Electrocatalysts for the Formation of Hydrogen Peroxide by Oxygen Reduction Reaction.

Hydrogen peroxide (HO) is a widely used strong oxidant, and its traditional preparation methods, anthraquinone method, and direct synthesis method, have many drawbacks. The method of producing HO by two-electron oxygen reduction reaction (2e ORR) is considered an alternative strategy for the traditional anthraquinone method due to its high efficiency, energy saving, and environmental friendliness, but it remains a big challenge. In this review, we have described the mechanism of ORR and the principle of electrocatalytic performance testing, and have summarized the standard performance evaluation techniques for electrocatalysts to produce HO.

Urea/Thiourea Imine Linkages Provide Accessible Holes in Flexible Covalent Organic Frameworks and Dominates Self-Adaptivity and Exciton Dissociation.

Unraveling the robust self-adaptivity and minimal energy-dissipation of soft reticular materials for environmental catalysis presents a compelling yet unexplored avenue. Herein, a top-down strategy, tailoring from the unique linkage basis, flexibility degree, skeleton electronics to trace-guest adaptability, is proposed to fill the understanding gap between micro-soft covalent organic frameworks (COFs) and photocatalytic performance. The thio(urea)-basis-dominated linkage within benzotrithiophene-based COFs induce the framework contraction/swelling (intralayer micro-flexibility) in response to tetrahydrofuran or water.
