hemoglobin modified with maleimide - activated polyethylene glycol

We have recently described human hemoglobin surfacemodified with polyethylene glycol (MP4, registered trademark Hemospan) that does not possess the vasoconstrictive properties which have hampered development of some hemoglobin-based oxygen carriers. Based on in vitro studies, we postulated that this lack of vasoconstriction is due to decreased diffusive oxygen transfer in the plasma space as a ...

Preparation and characterization of gliclazide-polyethylene glycol 4000 solid dispersions.

The objective of the present investigation was to study the effect of polyethylene glycol 4000 (PEG 4000) on in vitro dissolution of gliclazide from solid dispersions. Initial studies were carried out using physical mixtures of the drug and carrier. Solid dispersions were prepared by the melting or fusion method.Phase and saturation solubility study, in vitro dissolution of pure drug, physical ...

Preparation and Characterization of Modified Soda Lignin with Polyethylene Glycol

Soda lignin does not have thermal flowing characteristics and it is impossible for it to be further thermally molded. To achieve the fusibility of soda lignin for fiber preparation by melt-spinning, an effective method for soda lignin modification was conducted by cooking it with polyethylene glycol (PEG) 400 at various ratios. The higher the ratio of PEG that was used, the more PEG molecular c...

Preparation of Fe3O4Spherical Nanoporous Particles Facilitated by Polyethylene Glycol 4000

Much interest has been attracted to the magnetic materials with porous structure because of their unique properties and potential applications. In this report, Fe3O4nanoporous particles assembled from small Fe3O4nanoparticles have been prepared by thermal decomposition of iron acetylacetonate in the presence of polyethylene glycol 4000. The size of the spherical nanoporous particles is 100-200 ...
