Photoinitiator-free photopolymerisation of hydrogels for drug delivery including a cancer-tracing agent

open access: yes, 2005
Hydrogels were synthesised using the photoinitiator-free photopolymerisation technique for releasing drugs of different molar masses including a cancer-tracing agent (a porphyrin) in aqueous environments.

Controlled release of bovine serum albumin from electrospun fibrous membranes via an improved emulsion-core technique

open access: yes, 2011
Bovine serum albumin (BSA), entrapped in a water-in-oil emulsion as the core, was encapsulated in the shell polymer via emulsion-core (EC) coaxial electrospinning.

Haemocompatiblity of controlled release glass

open access: yesJournal of Materials Science: Materials in Medicine, 1998
There are many medical applications which benefit from the use of soluble biomaterials, including the sustained release of drugs over a precise period of time, or temporary conduits for controlling nerve regrowth. We have manufactured a series of phosphate-based controlled release glasses (CRGs) in which the solubility could be controlled by varying ...

Calcium Control of Neurotransmitter Release [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2011
Upon entering a presynaptic terminal, an action potential opens Ca(2+) channels, and transiently increases the local Ca(2+) concentration at the presynaptic active zone. Ca(2+) then triggers neurotransmitter release within a few hundred microseconds by activating synaptotagmins Ca(2+). Synaptotagmins bind Ca(2+) via two C2-domains, and transduce the Ca(

Development of Injection-Molded Swellable/Erodible Capsules for Oral Pulsatile Release

open access: yes, 2012
Swellable/erodible hydroxypropyl cellulose (HPC)-based capsular devices for pulsatile release were prepared by injection molding (IM) using a purposely-devised mold and a newly set up manufacturing process.

Zero-order drug release obtained with gradient matrix systems based on hydrophilic polymers

open access: yes, 2011
The use of powder layering technology was explored to prepare hydrophilic matrix systems aimed at a zero-order release of drugs. Systems with 5 layers with decreasing drug concentration from the inner to the outer one were prepared by applying powders ...
