Gadad PC, Matthews KH, Knott RM.
PMID: 24055598
Int J Pharm. 2013 Nov 30;457(1):40-9. doi: 10.1016/j.ijpharm.2013.09.006. Epub 2013 Sep 18.

Reduced oxygen tension combined with high glucose concentration leads to chronic wounds in diabetic patients. Delayed wound healing is due in part to impaired angiogenesis as a result of reduced endothelial cell migration. Topical applications, in the form of...

Solvent-cast films from three polymers, carboxymethylcellulose (CMC), sodium alginate (SA), and xanthan gum, were prepared by drying the polymeric gels in air. Three methods, (a) passive hydration, (b) vortex hydration with heating, and (c) cold hydration, were investigated to...

In vitro efficacy of antimicrobial wafers against methicillin-resistant Staphylococcus aureus.

Therapeutic delivery

Labovitiadi O, Lamb AJ, Matthews KH.
PMID: 22834076
Ther Deliv. 2012 Apr;3(4):443-55. doi: 10.4155/tde.12.27.

BACKGROUND: Lyophilized wafers have been developed as vehicles for the storage and delivery of therapeutic compounds to exuding wounds. The primary objective of this study was to incorporate a selection of antimicrobial compounds in karaya wafers and measure their...

Synthesis and blood compatibility evaluation of segmented polyurethanes based on cholesterol and phosphatidylcholine analogous moieties.

Biomaterials

Li YJ, Yokawa T, Matthews KH, Chen TM, Wang YF, Kodama M, Nakaya T.
PMID: 8922604
Biomaterials. 1996 Nov;17(22):2179-89. doi: 10.1016/0142-9612(96)00048-8.

New segmented polyurethanes based on cholesterol and phosphatidylcholine analogous moieties were synthesized. The soft segments used in this study were the poly(butadiene), poly(isoprene) or hydrogenated poly(isoprene) glycols; the hard segments of these segmented polyurethanes were composed of 4,4'-methylenediphenyl diisocyanate,...
