A phytochemical study on the flowe r of Calotropis gigantea (Linn.) using silica gel column chromatography and preparative thin layer chromatography, led to the first time isolation of Di-(2-ethylhexyl) phthalate (compound 1) and anhydrosophoradiol-3-acetate (compound 2). The structures of these compounds were confirmed by spectroscopic analyses (IR, HRTOFMS and NMR). The antibacterial and anti...

Complement activation during exposure of plasma to cuprophan has been postulated to cause leukopenia and hypoxia in hemodialysis patients. To determine if hypoxia is related to leukopenia and if complement activation leads to a depletion of functional complement components, we dialyzed four patients three times sequentially against each of four types of membranes: cuprophan, regenerated cellulo...

COMPRESSION BEHAVIOUR AND ENTERIC FILM COATING PROPERTIES OF CELLULOSE ESTERS Guo, H. X., 2002, Dissertations Biocentri Viikki Universitatis Helsingiensis 19/2002 pp. 40 ISBN 952-10-0653-6 (print), ISBN 952-10-0654-4 (pdf), ISSN 1239-9469 The main purpose of this study was to investigate the phenomena related to the compression behaviour and enteric film coating properties of pharmaceutical cel...

I DENTIFICATION of the abnormal polypeptide chain of a hemoglobin ( Hb ) variant is often useful in connection with structural analyses and Chernoff and Pettit’ have recently improved on existing methods for this purpose by using starch gel electrophoresis of globin in urea barbital buffer. Izzo2 used this same buffer for electrophoresis of globin on cellulose acetate. Ohba et al.3 have propose...

Uniformly-sized porous cellulose beads functionalized with amidoxime groups were prepared for the first time using a microfluidic method N-methylmorpholine N-oxide (NMMO) monohydrate as solvent. The molten state dope in NMMO (cell/NMMO dope) disperse phase and hot mineral oil continuous used T-junction chip to produce uniformly-sized cell/NMMO droplets. Coagulation of droplet at high temperatur...

The objective of this work was to study the feasibility of preparing cellulose acetate (CA) nanofibrous membranes by electrospinning with single solvent and their potential applying as affinity membrane. CA solutions in dichloromethane (DCM), formic acid, acetic acid and trifluoroacetic acid (TFA) were electrospun into nonwoven fiber membranes, respectively. The scanning electron microscope (SE...
