Phocaeicola coprophilus‐Derived 6‐Methyluracil Attenuates Radiation‐Induced Intestinal Fibrosis by Suppressing the IDO1‐Kynurenine‐AHR Axis

Advanced Science, EarlyView.
IR‐induced dysbiosis depletes P. coprophilus and its metabolite 6‐methyluracil, leading to disinhibition of the IDO1‐Kyn‐AHR axis. This results in sustained fibroblast activation and collagen deposition, driving radiation induced intestinal fibrosis. ABSTRACT Therapeutic options for radiation‐induced intestinal fibrosis (RIF) remain limited. This study

Stochastic disturbance regimes alter patterns of ecosystem variability and recovery.

PLoS ONE, 2020
Altered ecosystem variability is an important ecological response to disturbance yet understanding of how various attributes of disturbance regimes affect ecosystem variability is limited. To improve the framework for understanding the disturbance regime

Self‐Sustaining Piezozyme Platform for Antifouling via Mechanically Triggered Enzymatic Cascade

Advanced Science, EarlyView.
Wave‐powered CeO2/g‐C3N4 piezozyme coating converts ocean motion into an enzymatic H2O2‐to‐ROS cascade, realizing 180‐day eco‐friendly marine antifouling. ABSTRACT Harnessing ubiquitous mechanical energy for catalytic activation offers an emerging pathway toward self‐sustaining environmental protection systems.

Dung beetle community and functions along a habitat-disturbance gradient in the Amazon: a rapid assessment of ecological functions associated to biodiversity.

PLoS ONE, 2013
Although there is increasing interest in the effects of habitat disturbance on community attributes and the potential consequences for ecosystem functioning, objective approaches linking biodiversity loss to functional loss are uncommon.

Macrophage Extracellular Traps in Immunity and Cancer

Advanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.

Effects of large herbivores on grassland arthropod diversity [PDF]

, 2015
Both arthropods and large grazing herbivores are important components and drivers of biodiversity in grassland ecosystems, but a synthesis of how arthropod diversity is affected by large herbivores has been largely missing. To fill this gap, we conducted
