Abstract Hepatitis B–associated hepatocellular carcinoma (HCC) is often accompanied by severe vascular invasion and portal vein tumor thrombus, leading to a poor prognosis. However, the underlying mechanism of this disease remains obscure. In study, we demonstrate that hepatitis B virus (HBV)–encoded gene HBx induces high IL8 production through MEK–ERK signal activation, enhanced endothelial permeability facilitate invasion. metastatic model using tail injection in transgenic mouse with...

This work proposes a new literature topic clustering analysis framework, based on which the topics of digital-economy-related studies are condensed. First, we calculated word vector keywords using FastText model, and then were merged according to semantic similarity. A hierarchical method Jaccard coefficient was employed cluster domain documents. Finally, information gain applied estimate high-gain feature words for each category topics. Based above 23 categories research formed. We divided...

Hazard perception refers to a driver’s ability identify potential hazards on the road. Although studies have shown that overconfidence affects drivers’ perceive hazards, neural processing of hazard in overconfident drivers under different types has rarely been investigated. A mixed experimental design 2 (hazard type: no hazards) × (driver group: driver, control group) was used. total 120 images (60 with and 60 without were presented 25 group. Reaction time, response accuracy, P200 (200–250...

Performance evaluation of green supply chains (GSC) is an important tool to improve their comprehensive management. Identifying critical indicators crucial evaluation. This study examines the in performance evaluations GPC and provides relevant suggestions for managers GSCs’ performances. Firstly, we summarized 24 from five dimensions—financial value, customer service-level, business processes, innovation development, so-called level. Secondly, Delphi method was used determine formal...

Coniopteris simplex is a common component in many Jurassic floras. However, due to morphological variations sterile fronds and incomplete preservation of reproductive organs, its classification has been controversial for long time. Here, we present new material collected from the Middle Yan'an Formation Ordos Basin, Inner Mongolia. The reveals important characters, including hemi-dimorphic fronds, two forms pinnae, short-stalked sori sporangia on fertile annulus sporangium composed about 30...

Purpose Poor sleep quality is closed related with driving accidents. However, due to the lack of a valid instrument for assessing drivers’ quality, few studies have examined and its associations behaviours traffic accidents in China. The aim this paper revise Sleep Quality Scale (SQS) assess reliability validity Chinese drivers. Methods 522 drivers aged from 18 56 years old agreed complete SQS, Daytime Sleepiness Perception version 4 (DSPS-4), Self-report Risky Driving Behavior (RD-SR)...
