Cyclic pyrrole-imidazole polyamides targeted to the androgen response element [PDF]
, 2009 Hairpin pyrrole−imidazole (Py-Im) polyamides are a class of cell-permeable DNA-binding small molecules that can disrupt transcription factor−DNA binding and regulate endogenous gene expression.

Impact of E‐Beam Sterilization on Bioglass Composite Shape Memory Scaffolds
Macromolecular Materials and Engineering, EarlyView.Electron beam (E‐beam) sterilization is an attractive alternative to conventional methods (e.g., ethylene oxide) to sterilize medical devices such as scaffolds used to heal bone defects. Herein, the impact of E‐beam sterilization on the properties of “self‐fitting” shape memory polymer (SMP) scaffolds prepared from resorbable polyesters and a bioglass ...

Solution-phase synthesis of pyrrole-imidazole polyamides [PDF]
, 2009 Pyrrole−imidazole polyamides are DNA-binding molecules that are programmable for a large repertoire of DNA sequences. Typical syntheses of this class of heterocyclic oligomers rely on solid-phase methods. Solid-phase methodologies offer rapid assembly on

Macromolecular Rapid Communications, EarlyView.Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.

Lipidomic analysis and classification of Iberian dry‐cured hams with low field NMR
Food Frontiers, 2023 Iberian ham is a high‐quality food that is traditionally produced from black pigs that are native to the Iberian Peninsula. The taste and texture of Iberian ham are largely determined by its lipid content and composition.

Hyperpolarised benchtop NMR spectroscopy for analytical applications
Progress in Nuclear Magnetic Resonance SpectroscopyBenchtop NMR spectrometers, with moderate magnetic field strengths (B0=1-2.4T) and sub-ppm chemical shift resolution, are an affordable and portable alternative to standard laboratory NMR (B0≥7T). However, in moving to lower magnetic field instruments, sensitivity and chemical shift resolution are significantly reduced.
