Increased sensitivity in electron–nuclear double resonance spectroscopy with chirped radiofrequency pulses [PDF]

Magnetic Resonance
Electron–nuclear double resonance (ENDOR) spectroscopy is an EPR technique to detect the nuclear frequency spectra of hyperfine coupled nuclei close to paramagnetic centers, which have interactions that are not resolved in continuous wave EPR spectra and

EPR spectroscopy reveals antioxidant manganese defenses in the Lyme disease pathogen Borrelia burgdorferi [PDF]

mBio
Oxidative stress defense in aerobic bacteria relies on Mn-superoxide dismutase (MnSOD) and antioxidant Mn-metabolite complexes (H-Mn) to quench superoxide radicals (O2•−).

High FOXA1 levels induce ER transcriptional reprogramming, a pro-metastatic secretome, and metastasis in endocrine-resistant breast cancer

Cell Reports, 2023
Summary: Aberrant activation of the forkhead protein FOXA1 is observed in advanced hormone-related cancers. However, the key mediators of high FOXA1 signaling remain elusive.

Reverse dynamic nuclear polarisation for indirect detection of nuclear spins close to unpaired electrons [PDF]

Magnetic Resonance, 2022
Polarisation transfer schemes and indirect detection are central to magnetic resonance. Using the trityl radical OX063 and a pulse electron paramagnetic resonance spectrometer operating in the Q-band (35 GHz, 1.2 T), we show here that it is possible to ...
