Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The effects of human disturbance on the activity of wild reindeer in different physical condition
Rangifer, 1988 We compared two Norwegian wild reindeer herds, Knutsho in excellent physical condition and Hardangervidda in poor physical condition, before and during disturbance by human hunters in order to test whether physical condition effected foraging strategy under stress.

FEBS Letters, EarlyView.Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.

Attention and Awareness: Visual Psychophysics and Aversive Conditioning in Humans [PDF]
, 2006 We studied the neuronal correlates of consciousness by characterizing the role of attention and awareness in three psychophysical experiments. First, we investigated the role of visual awareness in the formation of afterimages, phenomena believed to ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential
FEBS Letters, EarlyView.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.
