Investigating transthyretin variants H88R and I107V in amyloid priming: From destabilization to complete dissociation

open access: yesThe FEBS Journal, EarlyView.
Investigated mutations in transthyretin (TTR) disrupt the F87‐centered hydrophobic core that stabilizes its tetrameric structure. The mild I107V mutation weakens inter‐chain packing, while H88R fully abolishes tetramer formation, yielding a monomeric, aggregation‐prone form. Structural, biophysical, and computational analyses reveal that both mutations

Hermit beetle (Osmoderma barnabita) habitat selection and movement are shaped by tree microhabitat availability in Eastern Romanian Carpathians

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted the first radio‐tracking study on Osmoderma barnabita to examine the movement ecology and habitat selection in the Eastern Carpathians. A female recorded the longest movement distance and had larger home ranges than males. It showed a preference for Quercus petraea, with wood mould cavities and DBH as key predictors.
