Exosome-Mediated Lectin Pathway and Resistin-MIF-AA Metabolism Axis Drive Immune Dysfunction in Immune Thrombocytopenia.

Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by reduced platelet levels and heightened susceptibility to bleeding resulting from augmented autologous platelet destruction and diminished thrombopoiesis. Although antibody-mediated autoimmune reactions are widely recognized as primary factors, the precise etiological agents that trigger ITP remain unidentified. The pathogenesis of ITP remains unclear owing to the absence of comprehensive high-throughput data, except for the belated emergence of autoreactive antibodies.

METTL3-Mediated m6A Modification of ISG15 mRNA Regulates Doxorubicin-Induced Endothelial Cell Apoptosis.

N6-adenosine methylation (m6A) of RNA is involved in the regulation of various diseases. However, its role in chemotherapy-related vascular endothelial injury has not yet been elucidated. We found that methyltransferase-like 3 (METTL3) expression was significantly reduced during doxorubicin (DOX)-induced apoptosis of vascular endothelial cells both in vivo and in vitro, and that silencing of METTL3 further intensified this process.

Synthesis of a Bimetallic-Doped Phytate-Melamine Composite as an Efficient Additive for Epoxy Resins with High Fire Safety.

The issue of hazardous smoke and toxic gases released from epoxy resins (EP), which often causes casualties in real fires, has limited its application.

Reduced brain network segregation in alcohol use disorder: Associations with neurocognition.

The human brain consists of functionally segregated networks, characterized by strong connections among regions belonging to the same network and weak connections between those of different networks. Alcohol use disorder (AUD) is associated with premature brain aging and neurocognitive impairments. Given the link between decreased brain network segregation and age-related cognitive decline, we hypothesized lower brain segregation in patients with AUD than healthy controls (HCs).

BEEx Is an Open-Source Tool That Evaluates Batch Effects in Medical Images to Enable Multicenter Studies.

The batch effect is a nonbiological variation that arises from technical differences across different batches of data during the data generation process for acquisition-related reasons, such as collection of images at different sites or using different scanners. This phenomenon can affect the robustness and generalizability of computational pathology- or radiology-based cancer diagnostic models, especially in multicenter studies. To address this issue, we developed an open-source platform, Batch Effect Explorer (BEEx), that is designed to qualitatively and quantitatively determine whether batch effects exist among medical image datasets from different sites.

Cross-regulation of RNA methylation modifications and R-loops: from molecular mechanisms to clinical implications.

R-loops, RNA-DNA hybrid structures, are integral to key cellular processes such as transcriptional regulation, DNA replication, and repair. However, aberrant accumulation of R-loops can compromise genomic integrity, leading to the development of various diseases. Emerging evidence underscores the pivotal role of RNA methylation modifications, particularly N6-methyladenosine (mA) and 5-methylcytosine (mC), in orchestrating the formation, resolution, and stabilization of R-loops.

Association between dietary inflammatory index score and incident dementia.

Introduction: We evaluated whether higher Dietary Inflammatory Index (DII) scores were associated with increased incidence of all-cause dementia and Alzheimer's disease (AD) dementia over 22.3 years of follow-up in the community-based Framingham Heart Study Offspring cohort.

Methods: One thousand four hundred eighty-seven participants (mean ± standard deviation, age in years 69 ± 6) completed food frequency questionnaires (FFQs) and had incident all-cause dementia and AD surveillance data available.

YTHDF2-dependent mA modification of FOXO3 mRNA mediates TIMP1 expression and contributes to intervertebral disc degeneration following ROS stimulation.

The accumulation of reactive oxygen species (ROS) significantly contributes to intervertebral disc degeneration (IDD), but the mechanisms behind this phenomenon remain unclear. This study revealed elevated ROS levels in the intervertebral discs (IVDs) of aged mice compared to those of younger mice. The local application of hydrogen peroxide (HO) near lumbar discs also induced ROS accumulation and IDD.
