Lower alpha, higher beta, and similar gamma diversity of saproxylic beetles in unmanaged compared to managed Norway spruce stands.

open access: yesPLoS ONE, 2022
Strong anthropogenic pressures on global forests necessitate that managed forests be evaluated as habitat for biodiversity. The complex pattern of habitat types created in forestry systems is ideal for analyses through the theoretical framework of alpha (

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Spatial Analysis of a mixed Beech, Spruce and Fir stand in the Eastern Alps [PDF]

open access: yes, 2010
In a forest reserve, located in the Eastern Italian Alps, a 4 ha permanent plot has been set up in a beech-spruce-fir multilayered forest, left to natural evolution for more than 30 years, in order to detect stand structure and spatial patterns ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Establishment of Heterobasidion annosum s.l. infections in young Norway spruce dominated stands [PDF]

open access: yes, 2013
One of the worst pathogens on Norway spruce, Heterobasidion annosum s.l., can establish in previously healthy trees by spores landing on freshly made stumps from where mycelia can grow via root grafts and contacts to the adjacent tree.

Effect of felling season, storage and drying on colour of silver birch (Betula pendula) wood from four different growing sites

open access: yesSilva Fennica, 2009
Darkening of birch wood during artificial drying is a significant problem regarding the use of its timber as raw material by the mechanical wood industry. In the future, an increasing proportion of birch timber will be obtained from plantation forests,

Population genetic diversity in Quercus robur and Ulmus laevis in Southern Urals (Russia): a comparatively study of adults and progeny in localities with contrast forest cover

open access: yesCentral European Forestry Journal, 2022
Extensive forest areas decreased and fragmented during anthropogenic development of the zone of broad-leaved forest tree species in Russia. The pedunculate oak (Quercus robur L.) and the European white elm (Ulmus laevis Pall.), important key components ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Ecological drivers of root grafting in balsam fir natural stands

open access: yes, 2020
International audienceNatural root grafts (anastomoses) result from the fusion of the vascular systems of two roots and allow trees to share water, nutrients and photosynthesis products, affecting tree growth and physiology.
