Objective: This study aimed to investigate the prognostic significance of dynamic contrast-enhanced computed tomography in patients with stage IA non-small cell lung cancer (NSCLC).
Methods: We retrospectively enrolled 139 patients (77 men, 62 women; mean age, 59 years) with stage IA NSCLC who underwent dynamic contrast-enhanced computed tomography. Data on age, pathologic subtype, peak enhancement, and net enhancement of primary lung cancer were collected and correlated with 5-year survival.
Results: Peak enhancement had a significant correlation with overall survival in the univariable analysis (hazard ratio [HR], 1.18, confidence interval [CI], 1.01-1.38; P = 0.04) and in the multivariable analysis (HR, 1.19; CI, 1.01-1.39; P = 0.04). Patients with peak enhancement of 90 Hounsfield unit or higher had a significantly increased risk of death compared with patients with less enhancement after curative surgery (HR, 4.15; CI, 1.23-13.95; P = 0.02).
Conclusions: Our study confirmed the prognostic significance of peak enhancement as an indicator for the overall survival of stage IA NSCLC.

Dissolved organic matter (DOM) plays a key role in grassland carbon biogeochemistry and shows sensitivity to global climate change, particularly nitrogen (N) deposition. We investigated the soil DOM molecular composition by UV-Vis and fluorescence spectroscopy, and FT-ICR MS through a N addition experiment (CK, N5, N10, N20, and N40 [0, 5, 10, 20, and 40 g N m-2 year-1, respectively]) in a desert steppe of northwest China. Moderate N inputs (N5-N20) caused a dose-dependent increase in DOM content (9.

Carvacrol (CAR) is a naturally occurring bioactive compound that is chemically unstable, and microencapsulation technology effectively protects its active components. Casein (CS) and chitosan (CH) were used for the first time as carriers to encapsulate CAR, forming highly stable carvacrol microcapsules (CAR@CS-CH). Under conditions of a 1:1 mass ratio of CS to CH and a pH of 5.

Introduction: This study explores how destination image shapes international tourists' satisfaction and loyalty in a heritage tourism setting, focusing on Mount Taishan as a case study. It investigates direct and indirect pathways, including mediating roles and demographic controls.
Methods: One thousand eight hundred international tourists were initially surveyed at Mount Taishan during the 2023 peak season, with 1650 valid responses retained after data cleaning.

Optimizing the collection chamber structure is critical for improving the reliability of electrostatic radon detectors, which are key to environmental and health risk monitoring. This study used COMSOL simulations to explore polonium-218 (Po, a radon progeny) ion collection parameters: chamber geometry, voltage, base material and structure, detector configuration, and edge electrification. Results showed that an uncharged base, combined with a detector protruding 2 mm above the base, enhances collection efficiency (CE); charged metal edge shielding boosts CE by 4-10 % without increasing collection time (CT); ∼2000 V balances peak CE and electromagnetic interference suppression.

Cerebral small vessel disease (CSVD) is a major yet underappreciated driver of cognitive impairment and dementia, contributing to nearly half of all cases. Emerging evidence indicates that CSVD is not merely a coexisting vascular condition but an active amplifier of neurodegeneration, operating through a self-perpetuating cascade of microvascular injury, blood-brain barrier (BBB) breakdown, and glymphatic system dysfunction. In this hypothesis-driven review, we propose the Integrated Vascular-Neurodegenerative Continuum, a mechanistic model in which vascular pathology triggers and accelerates neurodegeneration via intersecting pathways, including chronic cerebral hypoperfusion, oxidative stress, and APOE ε4-associated endothelial vulnerability.
