From overweight/obesity to metabolic syndrome: increased postoperative survival risk in gastric cancer

Overweight/obesity and metabolic syndrome (MetS) are recognized as potential risk factors for gastric cancer, but their impacts on postoperative morbidity and overall survival (OS) following radical gastrectomy remain controversial. We hypothesized that overweight/obesity and Met...

Clinical value of artificial intelligence ultrasound-assisted diagnostic system in the differential diagnosis of benign and malignant thyroid nodules

Accurately distinguishing the benign thyroid nodules (BTNs) and malignant thyroid nodules (MTNs) is crucial for treatment planning and prognosis. This study aims to explore the clinical value of artificial intelligence ultrasound-assisted diagnostic system (AI-UADS) in diagnosing...

Pan-retinal pathology detection in oct scans integrating natural language synthesis with diagnostic annotation

Abstract While OCT is pivotal for macular disease diagnosis, its adoption in primary care is limited by AI systems that cannot simultaneously analyze multi-sectional scans across the full spectrum of maculopathies or generate diagnostically integrated reports. Here we present iOC...

Causal association between air pollution and functional outcome after ischemic stroke: Evidence from 2-sample MR study

Observational studies have shown that air pollution may affect functional outcome following ischemic stroke. Our study aimed to explore the relationship between genetically predicted specific air pollutants and poststroke functional outcomes using the Mendelian randomization (MR)...

Ultralow Noise Orthogonal Fluxgates Enabling Weak Magnetic Field and Biomolecular Detection

Abstract Noninvasive detection of ultra-weak biomagnetic signals is crucial for modern biosensing, but conventional magnetic sensors are fundamentally limited by intrinsic noise. Orthogonal fluxgates (OFGs) enable high signal-to-noise-ratio detection of weak magnetic fields, yet...
