hydrogel nanocomposites based on alginate polysaccharide were prepared by graft copolymerization of acrylamide and itaconic acid in the presence of carbon nanotube, using methylene bisacrylamide and ammonium persulfate as crosslinker and initiator, respectively. the synthesized samples were characterized by infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy. the ...

in order to determine outcome of pregnancy with lui in patients with unexplained recurrent miscarriage whose husbands have low hypo-osmotic swelling test scores, a prospective clinical intervention was performed at a university referral clinic of recurrent abortion. out of 56 patients whose husbands had abnormal hypo-osmotic swelling tests, 43 patients underwent lui, from which only 14 patients...

Microencapsulation has become a common technique in the production of controlled release dosage forms. Many results have been reported, concerning the use of alginate beads as controlled release drug formulations. Alginate has a unique gel-forming property in the presence of multivalent cations, in an aqueous medium. Ibuprofen is an excellent analgesic and antipyretic, non-steroidal anti-inflam...

There has been significant progress in the last few decades in addressing the biomedical applications of polymer hydrogels. Particularly, stimuli responsive hydrogels have been inspected as elegant drug delivery systems capable to deliver at the appropriate site of action within the specific time. The present work describes the synthesis of pH responsive semi-interpenetrating network (semi-IPN)...

gum was extracted and characterized by material, proximate pasting properties.Terminalia in combination with sodium alginate at varying concentrations(0-80 %w/v) used preparing the microbeads ionotropic gelation using zincchloride as chelating agent. The were evaluated shape,size, swelling, buoyancy, entrapment efficiency, drug release profiles andkinetic modelling. spherical to ovoid shape siz...

Four types of Shiraz inlay (Khatam) samples were impregnated with nano-silver solution via spraying (S), a vacuum desiccator (VD), and immersion/dipping (I/D) for 2 h 24 techniques. The decay resistance dimensional stability evaluated after each treatment. specimens exposed to white-rot fungus 10 weeks by the agar-plate method, weight loss was determined assess decay. soaking in water measured....

The in vitro swelling action of L-thyroxine on rat liver mitochondria as examined photometrically represents an acceleration of a process which the mitochondria are already inherently capable of undergoing spontaneously, as indicated by the identical kinetic characteristics and the extent of thyroxine-induced and spontaneous swelling, the nearly identical pH dependence, and the fact that sucros...
