Characterisation of illicit ecstasy and diazepam tablets by colorant identification. (2018)
Journal Article
SHARRENBROCH, L., TOUGH, A. and MATTHEWS, K.H. 2018. Characterisation of illicit ecstasy and diazepam tablets by colorant identification. Analytical methods [online], 10(17), pages 2048-2055. Available from: https://doi.org/10.1039/c7ay02921g

Ecstasy and diazepam are two commonly abused drugs with a high potential for dependence. They are typically available as oral tablets that contain both the drug and other bulk components (excipients). Compositional knowledge of individual tablets off...

Colistin causes profound morphological alteration but minimal cytoplasmic membrane perforation in populations of Escherichia coli and Pseudomonas aeruginosa. (2018)
Journal Article
O'DRISCOLL, N.H., CUSHNIE, T.P.T., MATTHEWS, K.H. and LAMB, A.J. 2018. Colistin causes profound morphological alteration but minimal cytoplasmic membrane perforation in populations of escherichia coli and pseudomonas aeruginosa. Archives of microbiology [online], 200(5), pages 793-802. Available from: https://doi.org/10.1007/s00203-018-1485-3

Whilst colistin (polymyxin E) represents the last mainstream treatment option for multi-drug resistant Gram-negative pathogens, details of its mechanism of action remain to be fully resolved. In this study, the effects of sub-inhibitory, inhibitory-b...

Preformulation of cysteamine gels for treatment of the ophthalmic complications in cystinosis. (2016)
Journal Article
MCKENZIE, B., KAY, G., MATTHEWS, K.H., KNOTT, R. and CAIRNS, D. 2016. Preformulation of cysteamine gels for treatment of the ophthalmic complications in cystinosis. International journal of pharmaceutics [online], 515(1-2), pages 575-582. Available from: https://doi.org/10.1016/j.ijpharm.2016.10.044

Nephropathic cystinosis is a rare autosomal recessive disease characterised by raised lysosomal levels of cystine in the cells of all organs. It is treated by regular administration of the aminothiol, cysteamine. Corneal crystal deposition is one of...

Journal Article
MCKENZIE, B., KAY, G., MATTHEWS, K.H., KNOTT, R.M. and CAIRNS, D. 2015. The hen’s egg chorioallantoic membrane (HET-CAM) test to predict the ophthalmic irritation potential of a cysteamine-containing gel: quantification using Photoshop® and ImageJ. International journal of pharmaceutics [online], 490(1-2), pages 1-8. Available from: https://doi.org/10.1016/j.ijpharm.2015.05.023

A modified hen’s egg chorioallantoic membrane (HET-CAM) test has been developed, combining ImageJ analysis with Adobe® Photoshop®. The irritation potential of an ophthalmic medicine can be quantified using this method, by monitoring damage to blood v...
