This work deals with the computational modeling of passive myocardial tissue within the framework of mixed, non-linear finite element methods. We consider a recently proposed, convex, anisotropic hyperelastic model that accounts for the locally orthotropic micro-structure of cardiac muscle. A coordinate-free representation of anisotropy is incorporated(More)
Polymer coatings are essential for local delivery of drug from the stent platform. In designing a DES, it is critical to balance the hydrophilic and hydrophobic components of the polymer system to obtain optimal biocompatibility, while maintaining controlled drug elution. This study investigates the impact of polymer composition of the BioLinx polymer blend(More)
This study aimed to characterize inherent charge generated by micron-sized drug-only formulations of amorphous and crystalline salbutamol sulfate (SS). Amorphous SS was produced by spray-drying whilst crystalline SS was produced by conditioning spray-dried SS with supercritical CO2 and menthol. Electrostatic charge of the powders was characterized in two(More)
The development of stents has been a major advancement over balloon angioplasty, improving vessel revascularization in obstructive coronary artery disease. The development of drug-eluting stents (DES) was the next breakthrough, designed to prevent the development of neointimal hyperplasia (restenosis) following percutaneous coronary interventions (PCI).(More)
Inhaled pharmaceuticals are formulated and delivered differently according to the therapeutic indication. However, specific device-formulation coupling is often fickle, and new medications or indications also demand new strategies. The discontinuation of chlorofluorocarbon propellants has seen replacement of older metered dose inhalers with dry powder(More)
We present a simple, rapid method for detecting short DNA sequences that combines a novel isothermal amplification method (EXPAR) with visual, colorimetric readout based on aggregation of DNA-functionalized gold nanospheres. The reaction is initiated by a trigger oligonucleotide, synthetic in nature for this proof-of-principle study, which is exponentially(More)
Electrostatics continues to play an important role in pharmaceutical aerosols for inhalation. Despite its ubiquitous nature, the charging process is complex and not well understood. Nonetheless, significant advances in the past few years continue to improve understanding and lead to better control of electrostatics. The purpose of this critical review is to(More)
Dry powder inhalers have become increasingly attractive for pulmonary delivery of locally and systemically effective medications. In comparison to the liquid counterparts, such as nebulisation and pressurised metered dose inhalers, the powder form generally offers better chemical stability, improved portability and potentially superior patient adherence.(More)
