Membrane fouling, which is a key obstacle in implementing membrane technology, has been studied extensively for aqueous feeds. With increasing interests organic solvent applications, corresponding effort on understanding fouling warranted. This study employs molecular dynamics simulations to unveil the mechanisms underlying different adsorption behaviors of dextran onto polyacrylonitrile (PAN) ...

To elucidate the mechanism by which activation of the contact system of blood coagulation leads to expression of fibrinolytic activity, we have determined the molecular characteristics of the plasminogen activators present in dextran sulfate-treated euglobulin fractions by electrophoretic-zymographic analysis and specific immunoadsorption. In addition to free and protease inhibitor-bound tissue...

A rapid technique for the determination of iron in serum, after the intravenous injection of iron-dextran, is presented. Dithionite is used for the reduction of ferric to ferrous iron. The use of a detergent solution enables protein precipitation to be omitted. The iron reagent, 4: 7-diphenyl-1: 10-phenanthroline, and its ferrous complex are both soluble in the dilute detergent solution. Lipaem...

Comparative investigations were carried out regarding the efficiency of introduction of exogenous genes into cultured cells using a cationic polysaccharide DEAE-dextran-MMA (methyl methacrylate ester) graft copolymer (2-diethylaminoethyl-dextran-methyl methacrylate graft copolymer; DDMC) as a nonviral carrier for gene introduction. The results confirmed that the gene introduction efficiency was...

The work demonstrates a judicious approach to achieve hepatocyte cell-targeted highly efficient gene delivery by utilizing a supramolecular complex of galactosylated cucurbituril and dextran-spermine conjugates.

Ischemic stroke causes the depletion of energy and induces excitotoxicity and neuroinflammation in the brain that results from thrombotic blockage. Cerebral ischemia leads to many types of memory loss, including impairment of working, spatial and object recognition memoreis. Curcumin shows strong anti-oxidoinflammatory activities but it terapathics limited by its low solubility in water and cor...

unsuitable as colloidal infusion solutions, for which reason they are depolymerized by acid hydrolysis to products of suitable molecular size (average molecular weight 7500). This book constitutes a review of the history of the development of dextran to its present place, and a review of most of the literature available on the subject. The author, Anders Gr6nwall, is Professor of Clinical Chemi...

The nature of the interaction between dextran sulfate and low density human plasma lipoproteins of the Sr 0 to 10 class (LDL) was investigated by modifying LDL with succinic anhydride or acetic anhydride. In the absence of divalent metal ions, the formation of insoluble and soluble dextran sulfate-LDL complexes was prevented by the acylation of approximately 16% and 25%, respectively, of the LD...
