UHMWPE Modified Sodium Alginate

Materials Science Forum, 2015
Aim of our experiments was to modify prosthetic material UHMWPE powder using sodium alginate. The sodium alginate has an important property that the appropriate chemical reagent could exchange its Na+ions to Ca2+ions. The Ca has important role in the healing process, so modifying this substance the UHMWPE material helps patients healing.

Iron Binding by Sodium Alginate

Journal of Food Science, 1983
ABSTRACTSodium alginate was dispersed in iron chelate solutions and incubated for 10 min. The alginate was precipitated with acetone and the iron in the supernatant measured. Bound iron was calculated. The effects of pH, iron: alginate ratio, chelator, and competing cation on iron binding by alginate were determined.

Microencapsulation of oils using sodium alginate

Journal of Microencapsulation, 2000
The feasibility of encapsulating wheatgerm oil and evening primrose oil using sodium alginate by the emulsification method was explored in this study. It is based on the chemical reaction between the water-soluble sodium alginate and polyvalent cation, calcium, to form the water-insoluble alginate.

The depolymerization of sodium alginate by oxidative degradation

Pharmaceutical Development and Technology, 2011
Alginate has been extensively used as a carrier for macromolecules and as gene delivery vehicle. Both properties are molecular weight (Mw) dependent. Herein, we investigated factors affecting the oxidative depolymerization of alginate. The depolymerization process occurred mainly in the first 1 h.

Sodium Alginate Toughening of Gelatin Hydrogels

ACS Biomaterials Science & Engineering, 2017
Gelatin is a popular material for the creation of tissue phantoms due to its ease-of-use, safety, low relative cost, and its amenability to tuning physical properties through the use of additives. One difficulty that arises when using gelatin, especially in low concentrations, is the brittleness of the material.

Pharmacobezoar complicating treatment with sodium alginate

Journal of Gastroenterology, 2004
We encountered a gastric bezoar that had developed in a 9-year-old girl treated with sodium alginate (Alloid G) for acute gastritis associated with systemic lupus erythematosus. A hard mass palpated in the left upper abdomen proved, upon gastric endoscopy, to be an intragastric foreign body.

Metabolism and Calcium Antagonism of Sodium Alginate Oligosaccharides [PDF]

Bioscience, Biotechnology, and Biochemistry, 2007
Sodium alginate oligosaccharides (NaAOs) consisting of a mixture of eight oligosaccharides have previously been reported to lower blood pressure. We investigated in this study the excretion of NaAOs into the urine or feces, and attempted to elucidate the mechanism for lowering blood pressure by using isolated mesenteric arteries from the rabbit.

Controlled release of insecticide carbaryl from sodium alginate, sodium alginate/gelatin, and sodium alginate/sodium carboxymethyl cellulose blend beads crosslinked with glutaraldehyde

Journal of Applied Polymer Science, 2005
AbstractInterpenetrating network polymeric beads of sodium alginate (NaAlg) and its blend with gelatin (gels) or sodium carboxymethyl cellulose (NaCMC) have been prepared by crosslinking with a common crosslinking agent, glutaraldehyde (GA), for the release of insecticide carbaryl (Carb).

Dietary effects of sodium alginate in humans

Food Additives and Contaminants, 1991
Following a 7-day control period, five male volunteers consumed a weight of sodium alginate corresponding to 175 mg/kg body weight for 7 days, followed by 200 mg sodium alginate per kg body weight for a further 16 days. Measurements before and at the end of the 23-day period of dietary supplementation showed that sodium alginate acted as a faecal ...

Sodium alginate as a mould release agent

Biomaterials, 1985
The use of sodium alginate as a mould release agent during the casting of epoxy or polyester resins in plaster moulds is discussed. The optimal concentration of a retarder is determined, taking into consideration the setting behaviour and the adhesive bond strength.
