Personal exposure to static and time-varying magnetic fields during MRI procedures in clinical practice in the UK (2015)
Journal Article
Batistatou, E., Mölter, A., Kromhout, H., van Tongeren, M., Crozier, S., Schaap, K., …de Vocht, F. (in press). Personal exposure to static and time-varying magnetic fields during MRI procedures in clinical practice in the UK. Occupational and Environmental Medicine, 73, https://doi.org/10.1136/oemed-2015-103194

Background: MRI has developed into one of the most important medical diagnostic imaging modalities, but it exposes staff to static magnetic fields (SMF) when present in the vicinity of the MR system, and to radiofrequency and switched gradient electr...

Imaging gray matter with concomitant null point imaging from the phase sensitive inversion recovery sequence (2015)
Journal Article
Mougin, O., Abdel-Fahim, R., Dineen, R., Pitiot, A., Evangelou, N., & Gowland, P. (2016). Imaging gray matter with concomitant null point imaging from the phase sensitive inversion recovery sequence. Magnetic Resonance in Medicine, 76(5), 1512-1516. https://doi.org/10.1002/mrm.26061

Purpose

To present an improved three-dimensional (3D) interleaved phase sensitive inversion recovery (PSIR) sequence including a concomitantly acquired new contrast, null point imaging (NPI), to help detect and classify abnormalities in cortical g...

Association of Protein Phosphatase PPM1G With Alcohol Use Disorder and Brain Activity During Behavioral Control in a Genome-Wide Methylation Analysis (2015)
Journal Article
Ruggeri, B., Nymberg, C., Vuoksimaa, E., Lourdusamy, A., Wong, C. P., Carvalho, F. M., Jia, T., Cattrell, A., Macare, C., Banaschewski, T., Barker, G. J., Bokde, A. L., Bromberg, U., Büchel, C., Conrod, P. J., Fauth-Bühler, M., Flor, H., Frouin, V., Gallinat, J., Garavan, H., …Schumann, G. (2015). Association of Protein Phosphatase PPM1G With Alcohol Use Disorder and Brain Activity During Behavioral Control in a Genome-Wide Methylation Analysis. American Journal of Psychiatry, 172(6), 543-552. https://doi.org/10.1176/appi.ajp.2014.14030382

Objective: The genetic component of alcohol use disorder is substantial, but monozygotic twin discordance indicates a role for nonheritable differences that could be mediated by epigenetics. Despite growing evidence associating epigenetics and psychi...

Fat emulsion intragastric stability and droplet size modulate gastrointestinal responses and subsequent food intake in young adults (2015)
Journal Article

Background: Intragastric creaming and droplet size of fat emulsions may affect intragastric behavior and gastrointestinal and satiety responses.

Objectives: We tested the hypotheses that gastrointestinal physiologic responses and satiety will be i... Read More about Fat emulsion intragastric stability and droplet size modulate gastrointestinal responses and subsequent food intake in young adults.

Investigating the effects of an oral fructose challenge on hepatic ATP reserves in healthy volunteers: a 31P MRS study (2015)
Journal Article
Bawden, S., Stephenson, M., Ciampi, E., Hunter, K., Marciani, L., MacDonald, I. A., …Gowland, P. A. (in press). Investigating the effects of an oral fructose challenge on hepatic ATP reserves in healthy volunteers: a 31P MRS study. Clinical Nutrition, 35(3), https://doi.org/10.1016/j.clnu.2015.04.001

Background: Impaired homeostasis of hepatic ATP has been associated with NAFLD. An intravenous fructose infusion has been shown to be an effective challenge to monitor the depletion and subsequent recovery of hepatic ATP reserves using 31P MRS.
Aims... Read More about Investigating the effects of an oral fructose challenge on hepatic ATP reserves in healthy volunteers: a 31P MRS study.

Hemispheric asymmetry in cerebrovascular reactivity of the human primary motor cortex: an in vivo study at 7 T (2015)
Journal Article
Driver, I. D., Andoh, J., Blockley, N. P., Francis, S. T., Gowland, P. A., & Paus, T. (2015). Hemispheric asymmetry in cerebrovascular reactivity of the human primary motor cortex: an in vivo study at 7 T. NMR in Biomedicine, 28(5), 538-545. https://doi.org/10.1002/nbm.3282

Current functional MRI (fMRI) approaches assess underlying neuronal activity through monitoring the related local variations in cerebral blood oxygenation, blood volume and blood flow. This vascular response is likely to vary across brain regions and... Read More about Hemispheric asymmetry in cerebrovascular reactivity of the human primary motor cortex: an in vivo study at 7 T.

The effect of isocapnic hyperoxia on neurophysiology as measured with MRI and MEG (2015)
Journal Article
Croal, P. L., Hall, E. L., Driver, I. D., Brookes, M. J., Gowland, P. A., & Francis, S. T. (2015). The effect of isocapnic hyperoxia on neurophysiology as measured with MRI and MEG. NeuroImage, 105, https://doi.org/10.1016/j.neuroimage.2014.10.036

The physiological effect of hyperoxia has been poorly characterised, with studies reporting conflicting results on the role of hyperoxia as a vasoconstrictor. It is not clear whether hyperoxia is the primary contributor to vasoconstriction or whether... Read More about The effect of isocapnic hyperoxia on neurophysiology as measured with MRI and MEG.
