Modeling the continua in the outcomes of biotic interactions

open access: yesEcology, Volume 104, Issue 4, April 2023., 2023
Abstract The outcome of many ecological interactions lies somewhere along a continuum between pure positive and pure negative effects. Although the popularity of this idea has notoriously risen in the last decades, with the occurrence of continua in interaction outcomes invoked for a wide variety of interactions, the absence of a precise theoretical ...

Enhanced Gene Delivery Triggered by Dual pH/Redox Responsive Host‐Guest Dimerization of Cyclooligosaccharide Star Polycations

open access: yesMacromolecular Rapid Communications, Volume 43, Issue 11, June 2022., 2022
Star polycations consisting of a central trehalose‐based cyclooligosaccharide and radial tetraethyleneimine arms form supramolecular dimers with bis‐adamantane guests that are preorganized for pDNA condensation. The incorporation of a redox‐sensitive disulfide bridge on the guest structure enables a dual pH/redox‐sensitive regulation mechanism that ...
