Self-contracting, battery-free triboelectric wound healing strip with strong wet adhesion

Nature Communications
Conventional wound closure techniques, such as suturing and stapling, often cause infection, delayed healing, and tissue damage, particularly in fragile or compromised tissues.

Extended interface layer concept for higher stability and improvement of life time in bulk heterojunction solar cells

AIP Advances, 2015
Power conversion efficiency (PCE) of bulk heterojunction (BHJ) organic solar cells has reached above ∼10%. These BHJ cells have potential for flexible thin films at low processing temperatures using roll to roll printing on flexible substrates.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).
