A relation between historical forest use and current dead woody material in a boreal protected old-growth forest in Finland

Silva Fennica, 2005
Assessing the human impact on the naturalness and vegetation characteristics of protected areas is one of the key issues when designing forest conservation networks in Fennoscandia.

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

Advanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Effects of Norway Spruce (Picea abies) Stump Debarking on Insect Colonization in the Polish Sudety Mountains

Mountain Research and Development, 2016
This study aimed to determine whether debarking of Norway spruce stumps influences the intensity of their colonization by insects. The observed stumps of Picea abies (L.) H Karst were located in the eastern Sudety Mountains at elevations between 600 and ...

β‐Elemene Rescues Radiation‐Induced Enteritis by Orchestrating a Host‐Microbiome Circuit That Fuels Epigenetic DNA Repair

Advanced Science, EarlyView.
This study elucidates that β‐elemene promotes cellular uptake of L. gasseri‐derived lactate by enhancing the membrane translocation of MCT1 in a CD147‐dependent manner. Intracellular lactate, through the lactylation of RBBP4 at the K26 site, recruits EP300 to the promoter regions of downstream genes (POLD1/POLD3), catalyzing H3K27ac modification.

Stumps as fuel [PDF]

, 2012
Wood fuels make a key contribution to renewable energy sources in the Nordic countries. The growing demand for forest biomass can be partly met by utilising energy-rich stumps left after clear cutting.

ATF3 upregulation in glia during Wallerian degeneration: differential expression in peripheral nerves and CNS white matter [PDF]

, 2004
Background: Many changes in gene expression occur in distal stumps of injured nerves but the transcriptional control of these events is poorly understood.

Cyclic Mechanical Loading of Cardiomyocytes via Pressure‐Driven Non‐Planar Membrane Deformation in a Bioreactor System

Advanced Science, EarlyView.
In this research article, Mansoor and coworkers present a novel device that applies controlled mechanical stimuli to cardiomyocytes using pressure‐driven membrane deformation. By exposing cells to physiologically and pathologically relevant loading conditions, the platform reproduces distinct structural, functional and molecular responses associated ...
