Journal Article
Major, G., Pritchard, S. E., Murray, K., Alappadan, J. P., Hoad, C., Marciani, L., Gowland, P. A., & Spiller, R. C. (2017). Colon hypersensitivity to distension, rather than excessive gas production, produces carbohydrate-related symptoms in individuals with irritable bowel syndrome. Gastroenterology, 152(1), 124-133.e2. https://doi.org/10.1053/j.gastro.2016.09.062

Background & Aims: Poorly digested, fermentable carbohydrates may induce symptoms of irritable bowel syndrome (IBS), via unclear mechanisms. We performed a randomized trial with magnetic resonance imaging (MRI) analysis to investigate correlations be...

American Journal of Clinical Nutrition, 103(5), https://doi.org/10.3945/ajcn.115.125047

Background: Poorly absorbed, fermentable carbohydrates can provoke irritable bowel syndrome (IBS) symptoms by escaping absorption in the small bowel and being rapidly fermented in the colon in some susceptible subjects. IBS patients are often anxious... Read More about Corticotrophin releasing factor increases ascending colon volume after a fructose test meal in healthy humans: a randomised control trial.

Colonic response to laxative ingestion as assessed by MRI differs in constipated irritable bowel syndrome compared to functional constipation (2016)
Journal Article

Colonic response to laxative ingestion as assessed by MRI differs in constipated irritable bowel syndrome compared to functional constipation. Neurogastroenterology and Motility, 28(6), https://doi.org/10.1111/nmo.12784

Background

Functional constipation (FC) and irritable bowel syndrome with constipation (IBS-C) share many symptoms but underlying mechanisms may be different. We have developed a magnetic resonance imaging (MRI) technique to measure intestinal vol...

Magnetic resonance imaging biomarkers of gastrointestinal motor function and fluid distribution (2015)
Journal Article
Khalaf, A., Hoad, C., Spiller, R. C., Gowland, P. A., Moran, G. W., & Marciani, L. (2015). Magnetic resonance imaging biomarkers of gastrointestinal motor function and fluid distribution. World Journal of Gastrointestinal Pathophysiology, 6(4), https://doi.org/10.4291/wjgp.v6.i4.140

Magnetic resonance imaging (MRI) is a well established technique that has revolutionized diagnostic radiology. Until recently, the impact that MRI has had in the assessment of gastrointestinal motor function and bowel fluid distribution in health and...

Journal of Nutrition, 145(6), 1170-1177. https://doi.org/10.3945/jn.114.204339

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.

Effects of various food ingredients on gall bladder emptying (2013)
Journal Article
Marciani, L., Cox, E., Hoad, C., Totman, J. J., Costigan, C., Singh, G., Shepherd, V., Chalkley, L., Robinson, M., Ison, R., Gowland, P. A., & Spiller, R. C. (2013). Effects of various food ingredients on gall bladder emptying. European Journal of Clinical Nutrition, 67(11), https://doi.org/10.1038/ejcn.2013.168

Background/objectives: The emptying of the gall bladder in response to feeding is pivotal for the digestion of fat, but the role of various food ingredients in contracting the gall bladder postprandially is not well understood. We hypothesized that d... Read More about Effects of various food ingredients on gall bladder emptying.
