Hydrogels have become advantageous materials used in biomedical applications as catheter, soft contact lenses or drug carrying vehicle due to their features like biocompatibility, insoluble property aqueous solutions, resistance environmental conditions pH, temperature. Periodontitis is an inflammatory disease which leads the loss of tissue attachment, gingival recession, tooth periodontal pock...

In this study, the DNA sorption performance of diatomite-Zn(II) embedded supermacroporous monolithic p(HEMA) cryogels were investigated for the purpose of designing a novel adsorbent that can be utilized for DNA purification, separation and immunoadsorption studies such as removal of anti-dsDNA antibodies from systemic lupus erythematosus (SLE) patient plasma. Poly(2-hydroxyethyl methacrylate) ...

A series of polymers and copolymers of 2-hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA) were synthesized in order to find surfaces that would adsorb minimal amounts of protein. The adsorption of albumin, lysozyme and immunoglobulin G from a three-way mixture of these proteins in isotonic buffered saline to the polymers was measured using 125I-labeled proteins. Apparently high pr...

The present research work describes the synthesis and evaluation of new acrylic-type polymeric systems having degradable ester bonds linked to ibuprofen as materials for drug delivery. Ibuprofen was linked to 2-hydroxy-propyl methacrylate by an activated ester methodology in a one-pot procedure with a high yield. The resulting material was copolymerized with either 2-hydroxyethyl methacrylate o...

The efficacy of pretreatment on the dentin surface with an aqueous solution of glyceryl methacrylate (GM) was examined by measuring the wall-to-wall polymerization contraction of a light activated composite in a cylindrical dentin cavity, and by measuring the tensile bond strength to a flat dentin surface. All of the tested dentin surfaces were cleaned with neutralized 0.5 M EDTA and treated wi...

Adhesion of coagulase-negative staphylococci (CNS) was studied onto a homologous series of methacrylate polymers and copolymers. The materials varied in wettability (contact angles) and were either positively or negatively charged (zeta-potential). Bacterial adhesion experiments performed in a parallel-plate perfusion system showed that positively charged TMAEMA-Cl copolymers significantly prom...
