Research on Optimal Width of Coal Pillars in Both Sides of Abandoned Mining Areas and Tunnel Control Technology

Energy Science &Engineering, EarlyView.
This study primarily investigates the optimal width for coal pillar retention in both sides of the worked‐out face section. Taking the 42201 haulage roadway of the 42201 working face at Shengxin Coal Mine as the primary research target, it analyses the optimum width for coal pillar retention through theoretical calculations, numerical simulations, and ...

Continuous positive airway pressure increases CSF flow and glymphatic transport

JCI Insight, 2023
Respiration can positively influence cerebrospinal fluid (CSF) flow in the brain, yet its effects on central nervous system (CNS) fluid homeostasis, including waste clearance function via glymphatic and meningeal lymphatic systems, remain unclear.

Analysis and Optimization of Early‐Warning Indicators for Impact Critical Stress in Deep Soft Coal Seams

Energy Science &Engineering, EarlyView.
This study determines the impact critical stress early‐warning indicators for deep soft coal seams: 18 MPa (shallow holes), 20 MPa (deep holes), and 3 MPa/d daily stress change rate, via theoretical, experimental and simulation methods. ABSTRACT The accurate determination of early‐warning indicators for critical impact stress in deep soft coal seams is

Cost‐effectiveness of a randomized controlled trial comparing low‐dose aspirin to placebo for the prevention of recurrent preterm birth

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 399-407, April 2025.
Abstract To assess the cost‐effectiveness of low‐dose aspirin compared to placebo for the prevention of recurrent preterm birth from a healthcare perspective. This was a cost‐effectiveness analysis alongside a multicenter, randomized, double‐blinded, placebo‐controlled trial.

Intertwin birth weight discordance, mode of delivery, and fetal and neonatal outcomes in twin pregnancies

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective The aim of the present study was to evaluate the association between intertwin birth weight discordance and fetal and neonatal outcomes in twin pregnancies, and to assess its relationship with mode of delivery. Methods This retrospective cohort study included twin pregnancies delivered at a tertiary referral center.

The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

Single‐Cell Profiling Identifies CLEC5A+ Macrophages as Key Drivers of Thoracic Aortic Aneurysm Via CCL5‐Mediated M1 Polarization

Journal of Clinical Laboratory Analysis, EarlyView.
Thoracic aortic aneurysm (TAA) is a life‐threatening cardiovascular disease with limited therapeutic options. Through single‐cell RNA sequencing of aortic tissues from healthy individuals and TAA patients (105,541 cells), we identified CLEC5A+macrophages as the predominant pathogenic cell population exhibiting the highest M1 polarization score.
