A method of compensating for the excitability of spinal motoneurones when estimating the magnitude of potentials evoked in skeletal muscles

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend There is positive covariation in the amplitudes of motor evoked potentials (MEPs) in skeletal muscles generated by transcranial magnetic stimulation (TMS) of the motor cortex and in fluctuations in the excitability of spinal motoneurones – as indexed by electromyography (EMG), in the period (e.g. 100 ms) immediately preceding the

A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

open access: yesMagnetic Resonance in Chemistry, Volume 64, Issue 8, Page 711-728, August 2026.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

Study of prompt gamma and neutron emission for real‐time range verification in proton and carbon‐ion therapy

open access: yesMedical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...

Simulation‐Informed Evaluation of Microvascular Parameter Mapping for Diffusion MR Imaging of Solid Tumours

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 1, Page 387-402, July 2026.
ABSTRACT Purpose We aim to inform the design of new diffusion MRI (dMRI) approaches for microvasculature quantification that enhance the biological specificity of imaging towards cancer. Methods We adopted simulation‐informed modelling of the vascular dMRI signal. We synthesised signals from 1500 synthetic vascular networks, for a variety of protocols (
