Gas transport properties in thermally cured aromatic polyimide membranes
Aromatic polyimide derived from 2,2′-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride (6FDA) and 3,3′-diaminodiphenylsulfone (m-DDS) has been synthesized to facilitate the study of relationshipsExpand

Aligned electrospun nanofiber composite membranes for fuel cell electrolytes.
We have synthesized the novel composite membranes composed of sulfonated polyimide nanofibers and sulfonated polyimide for proton exchange membrane fuel cell. It was clear that the polyimides withinExpand

Preparation and properties of PLGA microspheres containing hydrophilic drugs by the SPG (shirasu porous glass) membrane emulsification technique.
In the present paper, monodisperse poly (lactide-co-glycolide) (PLGA) microspheres containing the hydrophilic model drug, blue dextran (BLD), were manufactured by the solvent evaporation method andExpand

Gas permeation stability of asymmetric polyimide membrane with thin skin layer: effect of molecular weight of polyimide
Abstract The gas permeation stability of an asymmetric polyimide membrane with a thin and defect-free skin layer has been investigated. The molecular weights of the polyimides used in this study wereExpand

Selective cell death by water-soluble Fe-porphyrins with superoxide dismutase (SOD) activity.
We investigated the effect on cell death of reactive oxygen species induced by [[5,10 (or 5,15)-bis(N-methyl-4-pyridyl)-15,20 (or 10,20) diphenyl]porphinato]iron (cis-FeMPy(2)P(2)P orExpand

Protective effects of the complex between manganese porphyrins and catalase-poly(ethylene glycol) conjugates against hepatic ischemia/reperfusion injury in vivo.
The complex between manganese (Mn) porphyrins and catalase-poly(ethylene glycol) (PEG) conjugates has been designed for the protective effect against hepatic ischemia/reperfusion injury in vivo. TheExpand

Superoxide dismutase as a target enzyme for Fe-porphyrin-induced cell death.
The cell viability of human cancer cell lines treated with [5,10-bis(N-methyl-4-pyridyl)-15,20-diphenyl]porphinatoiron(III) (cis-FeMPy(2)P(2)P) has been estimated. The cis-FeMPy(2)P(2)P is aExpand

Aminated poly(L-histidine) as new pH-sensitive DNA carrier.
The endosomal escape of the polyion complex between DNA and polycation is one of important factors for efficient gene expression. Here we have examined whether the poly(L-histidine) with severalExpand

Porphyrin-containing electrospun nanofibers: positional control of porphyrin molecules in nanofibers and their catalytic application.
Polyacrylonitrile nanofibers containing a series of porphyrin molecules were prepared by an electrospinning method. We first succeeded in controlling the position of porphyrin molecules in theExpand
