Covalently Linked Peptides and Membrane Potential Enable CyaA Segment Translocation
Advanced Science, EarlyView.Using a newly developed Droplet Interface Bilayer‐Pipette assay, the authors show that two segments of the CyaA toxin cross membranes by distinct mechanisms. One segment translocates spontaneously, whereas the translocation of the other depends on membrane potential.

Identification of isomeric unsaturated medium-chain dicarboxylic acids in human urine.
Journal of Lipid Research, 1989 Dicarboxylic aciduria caused by enhanced or inhibited fatty acid metabolism is usually described as increased urinary excretion of saturated medium-chain dicarboxylic acids, such as adipic, suberic, and sebacic acids.

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges
Advanced Science, EarlyView.Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

Advanced Science, EarlyView.Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

Advanced Science, EarlyView.A concept of integrated O2 and H2 gas therapy is achieved using a gas‐producing material. PMP nanoparticles, fabricated from platinum, MIL‐101(Fe)‐NH2, and phosphotungstic acid, are integrated into bilayer gelatin methacryloyl microneedles for transdermal delivery. These microneedles enable integrated O2 and H2 gas therapy and promote wound healing via
