Activation of notch signaling pathway is a potential mechanism for mucin2 reduction and intestinal mucosal barrier dysfunction in high-altitude hypoxia

open access: yesScientific Reports
High-altitude hypoxia can cause gastrointestinal issues and damage the intestinal mucosal barrier, which is crucial for digestion and nutrient absorption. The Notch signaling pathway affects this barrier’s integrity. This study explores the Notch pathway’

Origami‐Inspired Morphing Fuselage for Agile Fixed‐Wing Flight

open access: yesAdvanced Robotics Research, EarlyView.
Conventional aircraft steer with rigid control surfaces. SoAR instead replaces the fuselage itself with a cable‐driven origami continuum body that bends in 3D and compresses on demand. Whole‐fuselage morphing steers fixed‐wing flight: achieving sharp, near‐zero‐radius turns and rapid braking without ailerons, rudder, or elevator, while the same ...

China's Low‐Carbon Energy Transition Over the Past Two Decades: Experiences and Implications

open access: yesAdvanced Science, EarlyView.
China's low‐carbon energy transition features a brief decline and subsequent rebound in coal consumption, alongside the rapid expansion of renewable energy. This study develops a stage‐based analytical framework to explain this evolution from the perspectives of economic development, energy security, and environmental sustainability, revealing how ...

Remote ischemic preconditioning improves cognitive control in healthy adults: Evidence from an event-related potential study

open access: yesFrontiers in Neuroscience, 2022
It is suggested that remote ischemic preconditioning (RIPC) may be a promising treatment for improving healthy adults’ cognitive control. However, direct empirical evidence was absent. Therefore, this study aims to provide evidence for the impact of RIPC

Macrophage PABPC4‐SPP1 Axis Orchestrates Immunosuppression in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
In the CRC microenvironment, macrophage PABPC4 binds to the 3′UTR of SPP1 mRNA to stabilize its expression, thereby sustaining M2‐like immunosuppressive macrophage polarization. Concurrently, this axis suppresses CD8+ T cell effector functions via CD44 signaling, collectively fostering an immunosuppressive niche that drives tumor progression.
