Countercurrent Fractionation of Cellulose Derivatives with Porous Charcoal. II.

Embolization with cellulose porous beads, II: Clinical trial.

PURPOSE To evaluate the clinical applicability of cellulose porous beads (CPBs) as an embolic material for permanent vascular occlusion. METHODS Embolization with CPBs was performed in 16 patients, six with meningioma of the sphenoid wing, two with meningioma of the falx, three with meningioma of the tentorium, two with dural arteriovenous fistula, one with paraganglioma, and two with spinal ...

Fractionation of xyloglucan fragments and their interaction with cellulose.

Tamarind seed xyloglucan was partially degraded with a purified endoglucanase (endoV) from Trichoderma viride. Analysis by high-performance anion-exchange chromatography showed that this digest was composed of fragments consisting of 1 to 10 repeating oligosaccharide units ([xg]1-[xg]10). To study the adsorption of xyloglucan fragments to cellulose in detail, this digest was fractionated on Bio...

Thyroglobulin fractionation on diethylaminoethyl cellulose columns.

Thyroglobulin may be defined as the iodine-containing protein of the thyroid gland which has a sedimentation coefficient of 4o.w = 19 S, an electrophoretic mobility at pH 8.6 of approximately 5 x 10F5 cm2 volt-l set-1, and a steep salting out curve at about 38% ammonium sulfate saturation at neutral pH (1). Although other iodoproteins, both soluble in neutral salt and attached to cell particles...

Functionalization of Cellulose: Synthesis of Water-soluble Cationic Cellulose Derivatives

One of the trends of modern cellulose chemistry is the functionalization of known cellulose derivatives in order to expand their application area. In this work, water-soluble cationic cellulose derivatives containing up to 4% coupled nitrogen were obtained by the amination of hydroxyethylcellulose (HEC) with two different etherification agents, diethylepoxypropylamine (DEEPA) and (2-chlorethyl)...
