PURPOSE The aim of this study was to appraise the some mechanical properties of polymethyl methacrylate based denture base resin polymerized by copolymerization mechanism, and to investigate the cytotoxic effect of these copolymer resins. MATERIALS AND METHODS 2-hydroxyethyl methacrylate (HEMA) and isobutyl methacrylate (IBMA) were added to monomers of conventional heat polymerized and inject...

Room-temperature vulcanizing silicone and homopolymers of 2-hydroxyethyl methacrylate (HEMA) have been used to permanently inflate detachable balloons [1] . HEMA is preferred over silicone because it is less viscous and is water soluble. Goto et al. [2] described a commercially available (HEMA A, lnterventional Therapeutics, S. San Francisco, CA) polymerizing substance that includes HEMA as the...

Medical titanium alloy Ti-6Al-4V (TC4) has been widely used in the medical field, especially human tissue repair. However, TC4 some shortcomings, which may cause problems with biocompatibility and mechanical compatibility direct contact body. To solve this problem, physical gels are formed on surface of TC4, storage modulus gel matches that soft tissue. 2-bromoisobutyryl bromide (BIBB) dopamine...

BACKGROUND Based on clinical medications and related studies, we established a Yang-Gan Jie-Du Sang-Jie (YGJDSJ) herbal formula for hepatocarcinoma treatment. In present study, we evaluated the anti-cancer potential of YGJDSJ on suspension-grown human hepatocellular carcinoma Bel-7402 cells. METHODS Bel-7402 cells were cultured in poly(2-hydroxyethyl methacrylate) (poly-HEMA) coated plates an...

The surface imprinted technique was utilized in creating the synthetic lysozyme receptors on poly(hydroxyethyl methacrylate) [p(HEMA)] cryogel membrane with assistance of polydopamine under alkaline conditions. Following design artificial receptors, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscope (SEM) and swelling test were used for characterization studies adsorpt...

for the purpose of increasing the permeability to oxygen and equilibrium water content in contact lenses, polar copolymers with nonionic monomers such as 2-hydroxyethle methacrylate(hema) is used. by adding the polar monomers to (hema), the permeability to oxygen and equilibrium with water content is increased and also the absorption of proteins on lens surface is changed. in this research, the...
