in this study, porous scaffolds from poly(d,l-lactic acid) have been prepared via liquid- liquid phase separation method in ternary system of polymer-1,4-dioxane-water. polymer dissolved in dioxane in 1.5, 2.5 and 5 % wt/v and the solvent/non-solvent ratios were 13/87, 15/85 and 17/83. cloud point curves prepared by visual turbidometry. in order to obtain porous scaffolds with inter-connected p...
lysozyme, as a model protein, was precipitated through the formation of protein-zn complex to micronize for subsequent encapsulation within poly (lactic-co-glycolic acid) (plga) microspheres. various parameters, including ph, type and concentration of added salts and protein concentration, were modified to optimize the yield of protein complexation and precipitation. the resulting protein parti...
This article reports experimental data related to the research article entitled "Poly(malic acid-co-l-lactide) as a Superb Degradation Accelerator for Poly(l-lactic acid) at Physiological Conditions" (H.T. Oyama, D. Tanishima, S. Maekawa, 2016) [1]. Hydrolytic degradation of poly(l-lactic acid) (PLLA) blends with poly(aspartic acid-co-l-lactide) (PAL) and poly(malic acid-co-l-lactide) (PML) oli...
Poly(vinyl alcohol) and poly(vinyl pyrrolidone) were blended and films were obtained by casting method. Glutaraldehyde, hydrochloric acid and lactic acid were added to investigate their effect on mechanical properties, swelling and solubility of the blends with the aim to find a possible material candidate for medium or long term implants. Combination of all three additives (lactic acid, glutar...
Biocompatible graft copolymers from bacterial poly(γ-glutamic acid) and poly(lactic are realized using a “grafting to” approach combined with click chemistry.
