Development and Validation of an AI-Based Multimodal Model for Pathological Staging of Gastric Cancer Using CT and Endoscopic Images.

Rationale And Objectives: Accurate preoperative pathological staging of gastric cancer is crucial for optimal treatment selection and improved patient outcomes. Traditional imaging methods such as CT and endoscopy have limitations in staging accuracy.

Methods: This retrospective study included 691 gastric cancer patients treated from March 2017 to March 2024.

Targeted LNPs deliver IL-15 superagonists mRNA for precision cancer therapy.

Interleukin-15 (IL-15) emerges as a promising immunotherapeutic candidate, but the therapeutic utility remains concern due to the unexpected systematic stress. Here, we propose that the mRNA lipid nanoparticle (mRNA-LNP) system can balance the issue through targeted delivery to increase IL-15 concentration in the tumor area and reduce leakage into the circulation. In the established Structure-driven TARgeting (STAR) platform, the LNP and LNP can effectively and selectively deliver optimized IL-15 superagonists mRNAs to local and lungs, respectively, in relevant tumor models.

Trivalent recombinant protein vaccine induces cross-neutralization against XBB lineage and JN.1 subvariants: preclinical and phase 1 clinical trials.

A Systematic Method to Detect Next-Generation Sequencing-Based Microsatellite Instability in Plasma Cell-Free DNA: plasmaMSI.

Microsatellite instability (MSI) detection using tumor tissue is a well-established prognostic and predictive biomarker for certain types of cancers. However, tumor tissue samples are less convenient to obtain than blood plasma samples. The main challenge facing next-generation sequencing-based MSI detection in blood plasma samples is the ultralow signal/noise ratio in plasma cell-free DNA (cfDNA).

Arthroscopic V-Shaped Double-Pulley Suture-Bridge Repair of Massive Rotator Cuff Tear.

At present, suture bridge is a feasible choice in the treatment of massive rotator cuff tears (MRCTs). However, high tension on the repair site and medial tension during suture tightening and after medial knotting are unavoidable problems in MRCT repair with a suture bridge. Arthroscopic V-shaped double-pulley suture-bridge repair is a pragmatic surgical technique for the repair of MRCTs.

Roseburia intestinalis-derived butyrate alleviates neuropathic pain.

Approximately 20% of patients with shingles develop postherpetic neuralgia (PHN). We investigated the role of gut microbiota in shingle- and PHN-related pain. Patients with shingles or PHN exhibited significant alterations in their gut microbiota with microbial markers predicting PHN development among patients with shingles.

METTL4-Mediated Mitochondrial DNA N6-Methyldeoxyadenosine Promoting Macrophage Inflammation and Atherosclerosis.

Background: Mitochondrial dysfunction is a key factor in the development of atherogenesis. METTL4 (methyltransferase-like protein 4) mediates N6- methyldeoxyadenosine (6mA) of mammalian mitochondrial DNA (mtDNA). However, the role of METTL4-mediated mitoepigenetic regulation in atherosclerosis is still unknown.

Effects of preimplantation genetic testing for aneuploidy on embryo transfer outcomes in women of advanced reproductive age with no more than three retrieved oocytes.

Objective: To evaluate whether preimplantation genetic testing for aneuploidy (PGT-A) benefits women of advanced reproductive age (≥38 years old) with a diminished ovarian reserve (not more than three retrieved oocytes).

Design: A retrospective analysis comparing two groups: (a) PGT-A group: women who chose PGT-A and subsequent single re-warmed embryo transfers and (b) non-PGT-A group: women who chose not to genetically test their embryos and underwent subsequent fresh or re-warmed embryo transfers of one to two embryos on days 3 or 5.

Subjects: Two hundred thirty patients underwent PGT-A therapy, with 49 of these individuals undergoing more than one PGT-A cycle.

Enforced activation of the CREB/KDM2B axis prevents alcohol-induced embryonic developmental delay.

Unintentional, early pregnancy alcohol consumption affects embryonic development. During the peri-implantation stage, coinciding with the transition from naive to primed pluripotency, the long isoform of KDM2B (KDM2BLF) underlies the de novo establishment of polycomb repressive complex (PRC) functions at promoters after fertilization. However, it remains unclear whether and how ethanol exposure affects this spatiotemporal chromatin setting.

Development and validation of a prognostic and drug sensitivity model for gastric cancer utilizing telomere-related genes.

Background: Gastric cancer (GC) poses a major global health challenge because of its unfavorable prognosis. Elevated telomerase activity has been linked to the rapid growth and invasiveness of GC tumors. Investigating the expression profiles of telomerase could improve our understanding of the mechanisms underlying telomere-related GC advancement and its applicability as potential targets for diverse therapeutic strategies for GC.

Covalent DNA-Encoded Library Workflow Drives Discovery of SARS-CoV-2 Nonstructural Protein Inhibitors.

The COVID-19 pandemic, exacerbated by persistent viral mutations, underscored the urgent need for diverse inhibitors targeting multiple viral proteins. In this study, we utilized covalent DNA-encoded libraries to discover innovative triazine-based covalent inhibitors for the 3-chymotrypsin-like protease (3CL, Nsp5) and the papain-like protease (PL) domains of Nsp3, as well as novel non-nucleoside covalent inhibitors for the nonstructural protein 12 (Nsp12, RdRp). Optimization through molecular docking and medicinal chemistry led to the development of , a nonpeptide 3CL inhibitor with an IC of 0.

Middle Meningeal Artery Embolization for Nonacute Subdural Hematoma.

Background: The effect of embolization of the middle meningeal artery in patients with subacute or chronic subdural hematoma is uncertain.

Methods: We performed a multicenter, open-label, randomized trial in China, involving patients with symptomatic nonacute subdural hematoma with mass effect. Patients were assigned to undergo burr-hole drainage or receive nonsurgical treatment at the surgeon's discretion, and patients in each group were then randomly assigned, in a 1:1 ratio, to undergo middle meningeal artery embolization with liquid embolic material or to receive usual care.
