Polyethylenimine-graft-poly(ethylene glycol) copolymers: influence of copolymer block structure on DNA complexation and biological activities as gene delivery system.
For two series of polyethylenimine-graft-poly(ethylene glycol) (PEI-g-PEG) block copolymers, the influence of copolymer structure on DNA complexation was investigated and physicochemical properties… Expand

3D printing of five-in-one dose combination polypill with defined immediate and sustained release profiles.
We have used three dimensional (3D) extrusion printing to manufacture a multi-active solid dosage form or so called polypill. This contains five compartmentalised drugs with two independently… Expand

Different subcellular localization of Saccharomyces cerevisiae HMG-CoA reductase isozymes at elevated levels corresponds to distinct endoplasmic reticulum membrane proliferations.
In all eucaryotic cell types analyzed, proliferations of the endoplasmic reticulum (ER) can be induced by increasing the levels of certain integral ER proteins. One of the best characterized of these… Expand

Membrane protein retention in the yeast Golgi apparatus: dipeptidyl aminopeptidase A is retained by a cytoplasmic signal containing aromatic residues
The mechanism by which yeast dipeptidyl aminopeptidase (DPAP) A, type II integral membrane protein, is retained in the late Golgi apparatus has been investigated. Prior work demonstrated that the… Expand

Inkjet printing as a novel medicine formulation technique.
We demonstrate the viability of using an ink-jet printer to produce a formulation capable of controlling the release of a drug. This is shown for the drug felodipine, an antihypertensive, with… Expand
