in the past decade, electrospinning as a facile and effective means in producing nanofibers with diameters ranging from microns down to a few nanometers has been developed and considered important. in this work, electrospinning of an interesting natural biopolymer, sodium alginate, has been investigated. the results showed that water solution of sodium alginate cannot be electrospun into nanofi...

Oxidized sodium alginate is a handily modifiable polysaccharide owing to the pendant aldehyde groups which can form dynamic covalent bonds with amines, acylhydrazines, etc., providing oxidized sodium alginate-based hydrogels with stimuli-responsive properties. However, due to the stiffness and, in particular, the hydrophobicity of sodium alginate dialdehyde at low pH, the mechanical performance...

Department of Applied Physics, University of Fukui, Bunkyo 3-9-1, Fukui, 910-8507 Japan Abstract Sodium alginate solution, being viscous hydrocolloid, was examined voltammetrically in the context of viscous effects by use of a ferrocenyl compound as a redox probe. Voltammograms were almost independent of concentrations of sodium alginate even in a solid-like state. Diffusion coefficients of the...

Modification of polymers by covalent attachment of thiol bearing pendant groups is reported to impart many beneficial properties to them. Hence in the present study, sodium alginate-cysteine conjugate was synthesized by carbodiimide mediated coupling under varying reaction conditions and the derivatives characterized for thiol content. The thiolated alginate species synthesized had bound thiol ...

Recent advances in diagnostic technologies have revealed that nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious mucosal injury in the upper and lower gastrointestinal tract (including the small intestine). A drug to treat NSAID-induced small-intestinal injury (SII) is lacking. Sodium alginate is a soluble dietary fiber extracted from brown seaweed and its solution has been used as...

OBJECTIVE We investigated the mechanism of antihypertensive effects of sodium alginate oligosaccharides, which are enzymatic products of high-molecular-weight natural alginate from seaweeds, in Dahl salt-sensitive (Dahl S) rats. MATERIALS AND METHODS Dahl S rats fed a high-salt (4% NaCl) diet were subcutaneously administered sodium alginate oligosaccharides (60 mg/day using a continuous osmot...

OBJECTIVE Resveratrol has been shown to exert anti-inflammatory and antioxidant effects, while sodium alginate is a common pharmaceutic adjuvant with antioxidative and immunomodulatory properties. We performed an animal study to investigate the effect of sodium alginate addition to resveratrol on acute gouty arthritis. METHODS Twenty-four SPF Wistar mice were randomized to four groups receivi...
