pH‐Responsive Ultrasmall Iron Oxide Nanoassemblies for Activatable T2/T1 Magnetic Resonance Imaging
This research reports a pH‐responsive ultrasmall iron oxide nanoparticle (USIONs)/polymer nanoassemblies for activatable magnetic resonance imaging. Amphiphilic diphosphonic acid block copolymers compactly encapsulate USIONs to generate T2‐weighted contrast at physiological pH, while acidic conditions trigger disassembly, activating T1‐weighted ...

Noncanonical Peloruside A Biosynthesis by an Uncultivated Verrucomicrobiota Symbiont
Noncanonical biochemistry of the peloruside PKS characterized in this work, comprising double bond generation by a noncanonical tridomain (blue), acetyl‐CoA recycling (orange), and proofreading systems (purple and yellow). The Z‐double bond is installed by TEB1 through O‐acetylation and acetate elimination. The acyl ligase PelB (AL, orange) selectively

Engineered endotoxin‐free Escherichia coli were used to assemble poly(3‐hydroxybutyrate) (PHB) biopolymer particles displaying multiple conserved Burkholderia pseudomallei antigens via PhaC‐mediated surface presentation. Following formulation with poly(I:C), the particulate vaccines induced antigen‐specific humoral and cellular immune responses ...

1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...
