background chitosan is a naturally occurring biopolymer which has been widely used in a variety of biomedical applications including local antibiotic delivery due to its excellent mechanical properties, biodegradability and biocompatibility. beads are spherical, porous carriers which are prepared from various materials including chitosan. objectives the current study aimed to fabricate a new co...

Objective: To develop in-situ gel formulations of Lornoxicam for sustained release to reduce the dosing frequency in treatment rheumatoid arthritis. Methods: The method ion-sensitive formation was used this study. situ were prepared by varying concentrations sodium alginate as a bio-degradable gel-forming polymer, CaCl2 cross-linking agent, and chitosan, HPMCK4, HPMCK15, guar gum, gellan xantha...

We have determined the absolute phosphate content of microtubule-associated proteins (MAPs) and established that phosphorylation inhibits the actin filament cross-linking activity of MAPs and both of the major MAP components, MAP-2 and tau. Similar results were obtained with actin from rabbit muscle, hog brain, and Acanthamoeba castellanii. We used the endogenous phosphatases and kinases in hog...

The present invention relates to a soybean-based adhesive resin including a soybean flour and a cross-linking agent. The cross-linking agent is reacted with the functional groups in the soybean flour to form an adhesive resin. The present invention also relates to a method of making a soybeanbased adhesive resin. This method involves providing an aqueous solution of soybean flour and adding a c...

In this article, borax was used as the prime agent, and organic boron that cross-linked agent synthesized using adding sodium tartrate. The synthesis response shapes were optimized unmarried factor way. temperature opposition crosslinking time of fracturing fluid appraisal standards to decide boron. cross-linking agent's optimal statuses measured, chemical forcible holdings after with polyvinyl...

Poly(meth)acrylates are well-known commodity polymers widely used for coating applications due to easy production, low cost and interesting properties such as their relatively high thermal stability, resistance breakage transparency. Some of these can be improved by cross-linking, therefore an additional functionalization is necessary. Carbonate group allowed reaction with amines generate a ure...

The objective of the present investigation was to prepare and evaluate ocular inserts of moxifloxacin. An ocular insert was made from an aqueous dispersion of moxifloxacin, sodium alginate, polyvinyl alcohol, and dibutyl phthalate by the film casting method. The ocular insert (5.5 mm diameter) was cross-linked by CaCl2 and was coated with Eudragit S-100, RL-100, RS-100, E-100 or L-100. The in v...
