Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

The microbiome in human skin aging
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Glycerol supplementation in dairy cows and calves [PDF]
The production of biodiesel from rapeseed oil methyl ester leaves glycerol (synonym: glycerine, 1,2,3-propanetriol) as a valuable by-product and a promising feed supplement for farm animals. This thesis provides information about the supplemental feeding

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Establishment of contaminant-free perennial plants in vitro
Perennial plant tissue cultures are established by disinfecting field or greenhouse-grown plant parts and transferring them to sterile medium in vitro. Typically, shoots harvested from field or greenhouse-grown plants are placed in water, either to force

Reconstruction of destruction – in vitro reconstitution methods in autophagy research [PDF]
International audienceAutophagy is one of the most elaborative membrane remodeling systems in eukaryotic cells. Its major function is to recycle cytoplasmic material by delivering it to lysosomes for degradation.

Can a fermentation gas mainly produced by rumen Isotrichidae ciliates be a potential source of biohydrogen and a fuel for a chemical fuel cell? [PDF]
Bacteria, fungi and protozoa inhabiting the rumen – the largest chamber of the ruminants’ stomach, release large quantities of hydrogen during the fermentation of carbohydrates.

In vitro fermentability of prebiotic oligosaccharides by lactobacilli [PDF]
Twelve strains of lactobacilli were tested for their growth and ability to utilise six prebiotics (pure substances and commercially available prebiotics) as a sole carbon source. All strains showed a considerable growth on all prebiotics tested. Inulin was the best carbohydrate source for lactobacilli, followed by lactulose and raffinose.

Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
