Gender differences in systemic inflammatory and nutritional index following radical surgery for advanced gastric cancer.

Objectives: Albumin-globulin ratio (AGR), prognostic nutritional index (PNI), and platelet-to-lymphocyte ratio (PLR) have been validated as prognostic factors for gastric cancer (GC). However, significant gender differences exist in albumin levels and inflammatory cell counts, and further research is required to understand how these differences influence GC prognosis. This study aims to investigate the prognostic impact of nutritional and inflammatory indicators on GC patients undergoing radical surgery, as well as the influence of gender on these indicators' prognostic value.

Background: Prostate cancer (PCa) is a multifactorial and heterogeneous disease, ranking among the most prevalent malignancies in men. In 2020, there were 1,414,259 new cases of PCa worldwide, accounting for 7.3% of all malignant tumors.

Impact of thrombocytopenia on failure of endoscopic variceal treatment in cirrhotic patients with acute variceal bleeding.

Background: Acute variceal bleeding (AVB), a life-threatening complication of liver cirrhosis, can be effectively treated by endoscopy, but there is a risk of early rebleeding after endoscopic variceal treatment (EVT). Thrombocytopenia is the most common hemostatic abnormality in liver cirrhosis. However, it is still unclear about whether thrombocytopenia increases the failure of EVT in cirrhotic patients with AVB.

Simultaneous Isolation and Preparation of Extracellular Vesicles by Circular Multicavity Electrophoresis.

Extracellular vesicles (EVs) play a crucial role in diagnosis and treatment, yet obtaining highly purified EVs from complex biological samples is often hindered by nanoscale contaminants. In this work, considering the charge-to-size characteristics of EVs, a circular multicavity electrophoresis (CME) with gradient pore size distribution was constructed in the gradient electric field to realize the isolation and preparation of EVs. By the gradient gel sieving effect, small cell debris, EVs, and proteins in biological samples were gradually separated.

NSUN2-Mediated RNA 5-Methylcytosine Modification of PTEN Regulates Cognitive Impairments of Mice with Sleep Deprivation and Autophagy Through PI3K/AKT Signaling.

Background: Approximately 70% of chronic obstructive pulmonary disease (COPD) is underdiagnosed worldwide. We aimed to develop and validate a COPD self-evaluation questionnaire (COPD-EQ) that is better suited for COPD screening in China.

Methods: We developed a primary version of COPD-EQ based on the Delphi method.

Counterintuitive DNA destabilization by monovalent salt at high concentrations due to overcharging.

Monovalent salts are generally believed to stabilize DNA duplex by weakening inter-strand electrostatic repulsion. Unexpectedly, our force-induced hairpin unzipping experiments and thermal melting experiments show that LiCl, NaCl, KCl, RbCl, and CsCl at concentrations beyond ~1 M destabilize DNA, RNA, and RNA-DNA duplexes. The two types of experiments yield different changes in free energy during melting, while the results that high concentration monovalent salts destabilize duplexes are common.

Determining the Optimal Age for Extracranial-Intracranial Bypass Surgery: A Post Hoc Analysis of the CMOSS Randomized Trial.

Background: Previous trials have failed to demonstrate the benefits of extracranial-intracranial (EC-IC) bypass surgery for patients with carotid or middle cerebral artery occlusion. However, little evidence has focused on the effect of age on prognosis. This study aimed to explore whether EC-IC bypass surgery can provide greater benefits than medical therapy alone in specific age groups.

Robust interpolation of EEG/MEG sensor time-series via electromagnetic source imaging.

Objective: Electroencephalography (EEG) and Magnetoencephalography (MEG) are widely used non-invasive techniques in clinical and cognitive neuroscience. However, low spatial resolution measurements, partial brain coverage by some sensor arrays, as well as noisy sensors could result in distorted sensor topographies resulting in inaccurate reconstructions of underlying brain dynamics. Solving these problems has been a challenging task, This paper proposes a robust framework based on electromagnetic source imaging for interpolation of unknown or poor quality EEG/MEG measurements.

Indobufen-based Dual Antiplatelet Therapy in Patients with Multivessel Coronary Disease Undergoing Drug-eluting Stent Implantation Insight From the OPTION Trial.

Background: It remains unclear whether indobufen-based dual antiplatelet therapy (DAPT) preserves ischemic protection while limiting bleeding risk in patients with multivessel coronary disease (MVD). This study aimed to investigate the efficacy and safety of indobufen-based DAPT in patients with MVD.

Methods: Patients in the OPTION trial were stratified based on the presence of MVD.

Macropinocytosis enhances foamy macrophage formation and cholesterol crystallization to activate NLRP3 inflammasome after spinal cord injury.

After spinal cord injury (SCI), phagocytes endocytose myelin debris to form foam cells, exacerbating the inflammatory response. It has been previously shown that macrophages become foam cells through the phagocytosis of myelin debris via receptor-dependent mechanisms after SCI. Blocking receptor-mediated endocytosis did not completely prevent foam cell formation, so we investigated receptor-independent endocytosis.

A two-stage model for precise identification and Gleason grading of clinically significant prostate cancer: a hybrid approach.

Introduction: Accurate identification and grading of clinically significant prostate cancer (csPCa, Gleason Score ≥ 7) without invasive procedures remains a significant clinical challenge. This study aims to develop and evaluate a two-stage model designed for precise Gleason grading. The model initially uses radiomics-based multiparametric MRI to identify csPCa and then refines the Gleason grading by integrating clinical indicators and radiomics features.
