Application of In Vivo MRI Imaging to Track a Coated Capsule and Its Disintegration in the Gastrointestinal Tract in Human Volunteers (2022)
Journal Article

Oral specially coated formulations have the potential to improve treatment outcomes of a range of diseases in distal intestinal tract whilst limiting systemic drug absorption and adverse effects. Their development is challenging, partly because of li...

Emergent SARS-CoV-2 variants: comparative replication dynamics and high sensitivity to thapsigargin (2021)
Journal Article

The struggle to control the COVID-19 pandemic is made challenging by the emergence of virulent SARS-CoV-2 variants. To gain insight into their replication dynamics, emergent Alpha (A), Beta (B) and Delta (D) SARS-CoV-2 variants were assessed for thei...

Assessing lymphatic uptake of lipids using magnetic resonance imaging: A feasibility study in healthy human volunteers with potential application for tracking lymph node delivery of drugs and formulation excipients (2021)
Journal Article

Dietary lipids and some pharmaceutical lipid excipients can facilitate the targeted delivery of drugs to the intestinal lymphatics. Here, the feasibility of magnetic resonance imaging (MRI) for imaging lipid uptake into the intestinal lymphatics was...
