Impregnation of lumber due to the pressure of the impregnating liquid

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract Storage of the container is one of the most serious problems faced by the manufacturer. At temperatures above 5 °C, the fungus and blue stain affect the container board. Because of this, enterprises suffer losses, which most often occur due to the fact that customers reject wooden containers, since it is important to use wooden ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
