Polymer NMR spectroscopy. IX. Polyacrylamide

The NMR spectrum of polyacrylamide in aqueous solution exhibits a doublet resonance in the amide proton region, in contrast to the broad singlet shown by most smallmolecule amides. This is attributed to the relatively slow reorientation rate of the polymer segments, permitting effective coupling of the electric quadrupole moment of the N 14

Structure of the human PKD1-PKD2 complex | Science

Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disease that can lead to kidney failure. Mutations in the proteins PKD1 and PKD2 are linked to the disease, but the function of these proteins remains unclear, both in physiology and disease. PKD1 has been implicated in the sensing of chemical and mechanical force stimuli, and PKD2 is proposed to be a calcium ion channel.
