AbstractInclusion in nasogastric tube feeds (NGTF) of acid-sensitive, seaweed-derived alginate, expected to form a reversible gel in the stomach, may create a more normal intragastric state and modified gastrointestinal responses. This may ameliorate... Read More about A comparative, randomised MRI study of the physiological and appetitive responses to gelling (alginate) and non-gelling nasogastric tube feeds in healthy men.

Chronic constipation is a prevalent disorder that affects patients’ quality of life and consumes resources in healthcare systems worldwide. In clinical practice, it is still considered a challenge as clinicians frequently are unsure as to which treat...

PLoS ONE, 15(11), e0241441. https://doi.org/10.1371/journal.pone.0241441

Objective The gastrointestinal environment in which drug products need to disintegrate before the drug can dissolve and be absorbed has not been studied in detail due to limitations, especially invasiveness of existing techniques. Minimal in vivo dat...

Background

Magnetic resonance imaging (MRI) of the colonic response to a macrogol challenge drink can be used to assess the mechanisms underlying severe constipation. We measured the intra-subject reproducibility of MRI measures of colonic funct... Read More about The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge.

European Journal of Pharmaceutical Sciences, 134, 31-59. https://doi.org/10.1016/j.ejps.2019.04.003

The simultaneous intake of food and drugs can have a strong impact on drug release, absorption, distribution, metabolism and/or elimination and consequently, on the efficacy and safety of pharmacotherapy. As such, food-drug interactions are one of th... Read More about The mechanisms of pharmacokinetic food-drug interactions: A perspective from the UNGAP group.

Will MRI of gastrointestinal function parallel the clinical success of cine cardiac MRI? (2018)
Journal Article
Hoad, C., Clarke, C., Marciani, L., Graves, M. J., & Corsetti, M. (2018). Will MRI of gastrointestinal function parallel the clinical success of cine cardiac MRI?. British Journal of Radiology, 92(1093), https://doi.org/10.1259/bjr.20180433

Cine cardiac MRI is generally accepted as the “gold-standard” for functional myocardial assessment. It only took a few years after the development of commercial MRI systems for functional cardiac imaging to be developed, with electrocardiogram (ECG)-...
