Alyami, J., Ladd, N., Pritchard, S. E., Hoad, C. L., Abdul Sultan, A., Spiller, R. C., Gowland, P. A., MacDonald, I. A., Aithal, G. P., Marciani, L., & Taylor, M. A. (2017). Glycaemic, gastrointestinal and appetite responses to breakfast porridges from ancient cereal grains: a MRI pilot study in healthy humans. Food Research International, https://doi.org/10.1016/j.foodres.2017.11.071

Cereal grain based porridges are commonly consumed throughout the world. Whilst some data are available for varieties that are popular in the Western world such as oats and rye, other ‘ancient’ grains used in the East and in Africa such as millets ar...

Mechanistic Fluid Transport Model to Estimate Gastrointestinal Fluid Volume and Its Dynamic Change Over Time (2017)
Journal Article
Yu, A., Jackson, T., Tsume, Y., Koenigsknecht, M., Wysocki, J., Marciani, L., …Sun, D. (2017). Mechanistic Fluid Transport Model to Estimate Gastrointestinal Fluid Volume and Its Dynamic Change Over Time. AAPS Journal, 19(6), 1682-1690. https://doi.org/10.1208/s12248-017-0145-x

Gastrointestinal (GI) fluid volume and its dynamic change are integral to study drug disintegration, dissolution, transit, and absorption. However, key questions regarding the local volume and its absorption, secretion, and transit remain unanswered....

MRI assessment of the postprandial gastrointestinal motility and peptide response in healthy humans (2017)
Journal Article
Khalaf, A., Hoad, C., Menys, A., Nowak, A., Taylor, S. A., Paparo, S., …Moran, G. W. (2018). MRI assessment of the postprandial gastrointestinal motility and peptide response in healthy humans. Neurogastroenterology and Motility, 30(1), Article e13182. https://doi.org/10.1111/nmo.13182

Background: Feeding triggers inter-related gastrointestinal (GI) motor, peptide and appetite responses. These are rarely studied together due to methodological limitations. Recent MRI advances allow pan-intestinal, non-invasive assessment of motility... Read More about MRI assessment of the postprandial gastrointestinal motility and peptide response in healthy humans.

Magnetic resonance imaging quantification of fasted state colonic liquid pockets in healthy humans (2017)
Journal Article
Murray, K., Hoad, C. L., Mudie, D. M., Wright, J., Heissam, K., Abrehart, N., …Marciani, L. (2017). Magnetic resonance imaging quantification of fasted state colonic liquid pockets in healthy humans. Molecular Pharmaceutics, 14(8), 2629-2638. https://doi.org/10.1021/acs.molpharmaceut.7b00095

The rate and extent of drug dissolution and absorption from solid oral dosage forms is highly dependent on the volume of liquid in the gastrointestinal tract (GIT). However, little is known about the time course of GIT liquid volumes after drinking a...

Clinical assessment of gastric emptying and sensory function utilizing gamma scintigraphy: Establishment of reference intervals for the liquid and solid components of the Nottingham test meal in healthy subjects (2017)
Journal Article
Parker, H. L., Tucker, E., Blackshaw, E., Hoad, C., Marciani, L., Perkins, A., …Fox, M. (2017). Clinical assessment of gastric emptying and sensory function utilizing gamma scintigraphy: Establishment of reference intervals for the liquid and solid components of the Nottingham test meal in healthy subjects. Neurogastroenterology and Motility, 29(11), e13122. https://doi.org/10.1111/nmo.13122

Background: Current investigations of stomach function are based on small test meals that do not reliably induce symptoms and analysis techniques that rarely detect clinically relevant dysfunction. This study presents the reference intervals of the m...

Assessment of motion of colonic contents in the human colon using MRI tagging (2017)
Journal Article
Pritchard, S. E., Paul, J., Major, G., Marciani, L., Gowland, P. A., Spiller, R. C., & Hoad, C. (2017). Assessment of motion of colonic contents in the human colon using MRI tagging. Neurogastroenterology and Motility, 29(9), Article e13091. https://doi.org/10.1111/nmo.13091

Background We have previously reported a non-invasive, semi-automated technique to assess motility of the wall of the ascending colon (AC) using Magnetic Resonance Imaging. This study investigated the feasibility of using a tagged MRI technique to vi... Read More about Assessment of motion of colonic contents in the human colon using MRI tagging.

Endotoxemia in peritoneal dialysis patients: a pilot study to examine the role of intestinal perfusion and congestion (2017)
Journal Article
Grant, C., Harrison, L., Hoad, C., Marciani, L., Cox, E., Buchanan, C., …McIntyre, C. (2017). Endotoxemia in peritoneal dialysis patients: a pilot study to examine the role of intestinal perfusion and congestion. Peritoneal Dialysis International, 37(1), 111-115. https://doi.org/10.3747/pdi.2016.00079

Endotoxemia is common in advanced chronic kidney disease and is particularly severe in those receiving dialysis. In hemodialysis patients, translocation from the bowel occurs as a consequence of recurrent circulatory stress leading to a reduction in...
