BACKGROUND Polyacrylamide hydrogel (PAAG) injection for breast augmentation can result in a variety of complications, including implant migration. The migrated PAAG can become colonized by pathogens, resulting in secondary infections which can be extremely difficult to treat. CASE REPORT We report the case of a 43-year-old female patient who underwent PAAG injection for breast augmentation. I...
A new hydrogel based on vinylsilane-chitosan and acrylamide was synthesized as VSi-CTS-g-PAAm used to remove methylene blue (MB) from aqueous solution using batch adsorption technique. The VSi-CTS-PAAm interacted with dye at different mass-liquid ratios, pH, temperature. amount of MB removal estimated a UV-Vis spectrophotometer an optical density λmax= 665 nm. most effective pH 12, about 98 % 5...
Polyacrylamide hydrogel (PAAG) has been used for several years as an injectable implant for augmentation mammoplasty in China. Although patients who received PAAG injections experienced a number of complications, breast cancer following PAAG injection has been reported only in two cases. In this report, we present a case of breast cancer following PAAG injection for breast augmentation. Our stu...
Successful regeneration of biological tissues in vitro requires the utilization of three-dimensional (3D) scaffolds that provide a near natural microenvironment for progenitor cells to grow, interact, replicate, and differentiate to form target tissues. In this work, a rapid aqueous photo-polymerization route was developed toward the fabrication of a variety of polymer hydrogel 3D inverted coll...
To gain insight into the fundamental processes determining the motion of macromolecules in polymeric matrices, the dynamical hindrance of polymeric dextran molecules diffusing as probe through a polyacrylamide hydrogel is systematically explored. Three complementary experimental methods combined with Brownian dynamics simulations are used to study a broad range of dextran molecular weights and ...
Physically crosslinked hydrogels consisting of polyacrylamide (Aam) and polyoctadecylacrylate (C18A) blocks, leading to hydrophilic hydrophobic domains respectively, are prepared by micellar polymerization. A multifunctional monomer (divinylbenzene, DVB), is also employed create branched chains. The effect the polymer composition amount branching agent on material characteristics evaluated. mel...
