2‐Hydroxyethyl methacrylate as an inhibitor of matrix metalloproteinase‐2
European Journal of Oral Sciences, 2009This study evaluated the effect of different concentrations of 2‐hydroxyethyl methacrylate (HEMA) on the inhibition of matrix metalloproteinase‐2 (MMP‐2) in vitro. Mouse gingival explants were cultured overnight in Dulbecco’s modified Eagle’s minimal essential medium, following which the expression of secreted enzymes was analyzed by gelatin zymography

Wettability of hydrogels I. Poly(2‐hydroxyethyl methacrylate)
Journal of Biomedical Materials Research, 1975AbstractThe wettability characteristics of the contact lens material, PHEMA, with respect to water have been determined by using the sessile drop, and the captive air bubble techniques of contact angle goniometry. It is concluded that on PHEMA gels water does not spread spontaneously.

Polymerisation and degradation of 2-hydroxyethyl methacrylate and 2-ethoxyethyl methacrylate
2023The real time bulk polymerisation of 2-hydroxyethyl methacrylate (HEMA) and 2-ethoxyethyl methacrylate (EEMA) initiated with benzoyl peroxide has been studied over a range of initiator concentrations and polymerisation temperatures with the purpose of evaluating the kinetic rate parameters for polymerisation across the entire range of conversion ...

Materials & Design, 2009
Abstract The influence of 2-hydroxyethyl methacrylate (HEMA) on the properties of HEMA-added dental glass ionomer (HAGI) should be determined systematically to develop a smart restorative material. The purposes of this study were to determine the influence of incrementally added HEMA in experimental HAGIs on the color, translucency, opalescence ...

Water transport in crosslinked 2‐hydroxyethyl methacrylate
Polymer Engineering & Science, 2000AbstractWater transport in crosslinked 2‐hydroxyethyl methacrylate (HEMA) was investigated. Crosslinked HEMA was irradiated by gamma ray in vacuum for this study. The sorption data of de‐ionized water transport in crosslinked HEMA subjected to various gamma ray dosages are in excellent agreement with Harmon's model which accounts for Case I, Case II ...

Journal of Applied Polymer Science, 1997
The elastic and swelling behavior of copolymers of 2-hydroxyethyl methacrylate, diethylene glycol methacrylate, and methacrylic acid crosslinked with ethylene glycol dimethacrylate has been studied. In the range of copolymer composition studied, Young's modulus of the swollen networks increases with the content of methacrylic acid, and its dependence ...

2‐Hydroxyethyl methacrylate inflammatory effects in human gingival fibroblasts
International Endodontic Journal, 2012AbstractAimTo investigate the inflammatory response in human gingival fibroblasts (HGFs) treated with a relatively low 2‐hydroxyethyl methacrylate (HEMA) concentration by studying reactive oxygen species (ROS) production, cyclooxygenase‐2 (COX‐2) and tumour necrosis factor‐alpha (TNF‐α) gene expression, and prostaglandin E2 (PGE2) release ...

The unperturbed dimensions of poly(2‐hydroxyethyl methacrylate)
Die Makromolekulare Chemie, 1977AbstractValues of the unperturbed dimensions of poly(2‐hydroxyethyl methacrylate) have been determined in five non‐ideal solvents using viscometric data and a number of different theoretical treatments. Values of the steric factor σ, the characteristic ratio C∞ and the expansion factor α were also calculated.
