Multi‐Omics Insights Into the Mechanisms of Early Muscle Fiber Difference and Transformation Between Lean‐Type and Chinese Indigenous Pigs

Advanced Science, EarlyView.
Multi‐omics analyses uncover breed‐specific cis‐regulatory landscapes and higher‐order chromatin architectural differences that underlie early postnatal muscle fiber divergence in pigs. A super‐enhancer upstream of PPP3CB recruits MEF2C to activate PPP3CB transcription, while the PPP3CB–MEF2C positive feedback loop promotes oxidative muscle fiber ...

Tropical forests and global atmospheric change: a synthesis [PDF]

, 2004
We present a personal perspective on the highlights of the Theme Issue 'Tropical forests and global atmospheric change'. We highlight the key findings on the contemporary rate of climatic change in the tropics, the evidence--gained from field studies--of

Erasable FAP Targeted Spray‐On Probe for Fluorescence‐Guided Surgery

Advanced Science, EarlyView.
We present the first erasable spray‐on probe for fluorescence‐guided surgery. Following topical delivery, FAP‐FLASH550 targets fibroblast activation protein–expressing stromal cells, delineating tumor margins with high tumor‐to‐background ratios. A 365 nm UV light pulse rapidly erases fluorescent signals through triazene photodegradation and subsequent

Variability and dynamics of old-growth forests in the circumboreal zone: implications for conservation, restoration and management

Silva Fennica, 2011
Due to the unprecedented loss of old-growth forests to harvesting throughout circumboreal regions an understanding of similarities and differences in old-growth dynamics is needed to design effective restoration, management and conservation efforts ...

Tropical forest degradation in the context of climate change: increasing role and research challenges. [K-2215-01] [PDF]

, 2015
While developed countries in temperate regions faced their forest transition about 100 years ago or more, “tropical forest rich” nations still largely depend on forest resources or land clearing for their development.

A Hydrogen‐Releasing Nanozyme Engineers a Mitochondrial ROS Amplifier for Self‐Sustaining Catalytic Immunotherapy

Advanced Science, EarlyView.
We developed a RhPd‐H nanozyme that integrates enhanced POD‐mimetic catalytic activity with thermally triggered H2 release. H2 shields and reprograms mitochondria to continuously leak endogenous ·O2−. This dual‐path ROS spatially and temporally disrupts redox homeostasis, inducing persistent oxidative stress for tumor suppression and antitumor immunity,

Are old-growth forests still able to accumulate carbon?

Forest@, 2006
A recent paper published in Science (Zhou et al. 2006) reports an unexpectedly high accumulation of carbon in the top 20-cm soil layer in a preserved old-growth forest in southern China during 24 years.

Living among Frequent-fire Forests: Human History and Cultural Perspectives

Ecology and Society, 2007
Ecological and social factors shaped old-growth forests of the western United States before Euro-American settlement, and will, in large part, determine their future.

Fragmentation Increases Impact of Wind Disturbance on Forest Structure and Carbon Stocks in a Western Amazonian Landscape [PDF]

Tropical second-growth forests could help mitigate climate change, but the degree to which their carbon potential is achieved will depend on exposure to disturbance.
