Objective. Magnetic resonance elastography (MRE) is widely adopted as a biomarker of liver fibrosis. However, in vivo MRE accuracy is difficult to assess. Approach. Finite element model (FEM) simulation was employed to evaluate liver MRE accuracy and... Read More about In silico evaluation and optimisation of magnetic resonance elastography of the liver.

Comparison of continuous sampling with active noise cancellation and sparse sampling for cortical and subcortical auditory fMRI (2021)
Journal Article

Purpose
Detecting sound-related activity using functional MRI requires the auditory stimulus to be more salient than the intense background scanner acoustic noise. Various strategies can reduce the impact of scanner acoustic noise, including “sparse...

Muscle and tendon adaptations to moderate load eccentric vs. concentric resistance exercise in young and older males (2021)
Journal Article
Quinlan, J. I., Franchi, M. V., Gharahdaghi, N., Badiali, F., Francis, S., Hale, A., …Narici, M. V. (2021). Muscle and tendon adaptations to moderate load eccentric vs. concentric resistance exercise in young and older males. GeroScience, 43(4), 1567-1584. https://doi.org/10.1007/s11357-021-00396-0

Resistance exercise training (RET) is well-known to counteract negative age-related changes in both muscle and tendon tissue. Traditional RET consists of both concentric (CON) and eccentric (ECC) contractions; nevertheless, isolated ECC contractions...

Brain and Behavior, 11(7), Article e02126. https://doi.org/10.1002/brb3.2126

Introduction: Resting cerebral blood flow (CBF) and perfusion measures have been used to determine brain health. Studies showing variation in resting CBF with age and fitness level using different imaging approaches have produced mixed findings. We a...

Frontiers in Physiology, 12, Article 656746. https://doi.org/10.3389/fphys.2021.656746

Cerebrovascular reactivity (CVR) is used as an outcome measure of brain health. Traditionally, lower CVR is associated with ageing, poor fitness and brain-related conditions (e.g. stroke, dementia). Indeed, CVR is suggested as a biomarker for disease...
