infusion-based flow

The limited understanding of solute transport in brain white matter tissue has hindered optimisation of infusion-based drug delivery therapies. This paper describes the first direct measurement of hydraulic permeability in white matter subjected to infusion. Our experiments reveal the dependency of hydraulic permeability on the alignment between the flow direction and the orientation of the axonal fibres. This is particularly relevant for the successful development of infusion-based technologies for treatment of lethal tumours in brain, such as convection-enhanced delivery, which are based on the direct injection of drugs under positive pressure into the brain. read more
