Methacrylic Acid is an organic acid used at concentrations between 50 and 88 percent to pretreat the nail and maximize the adhesion between the nail and artificial nail extender. Methacrylic Acid is readily absorbed through mucous membranes of the lungs, the gastrointestinal tract, and the skin; and
Polyacrylate films in the absence of added endotoxin caused rat peritoneal macrophages to secrete a small amount of TNFalpha. There was little difference, if any, among the materials, which included various co- or ter-polymers of hydroxyethyl methacrylate, dimethylaminoethyl methacrylate,
Toxicology and carcinogenesis studies of methyl methacrylate, a liquid chemical intermediate used in the plastics industry in the manufacture of plexiglass and other acrylic products, were conducted by exposing groups of F344/N rats and B6C3F1 mice by inhalation for 14 weeks and 2 years. In the
Iron-platinum nanoparticles embedded in a poly(methacrylic acid) (PMA) polymer shell and fluorescently labeled with the dye ATTO 590 (FePt-PMA-ATTO-2%) are investigated in terms of their intracellular localization in lung cells and potential to induce a proinflammatory response dependent on
Water-soluble chitosan having double bonds (CS-MA-LA) was synthesized by sequential grafting of methacrylic acid (MA) and lactic acid (LA) via the reaction between amino groups and carboxyl groups under the catalysis of carbodiimide. Its molecular structure was verified by FTIR and (1)H NMR
Bacterial microleakage along the tooth/composite resin dental restoration interface contributes to post-operative sensitivity, recurrent caries, pulp inflammation and necrosis. Studies have confirmed that saliva can catalyze the degradation of constitutive monomers in dental restorative composites,
Bacterial microleakage along the tooth/composite resin dental restoration interface contributes to postoperative sensitivity, recurrent caries, and necrosis. Studies have confirmed that enzymes in human saliva degrade composite resin monomers 2,2-bis [4-(2-hydroxy-3-methacryloxypropoxy) phenyl]
BACKGROUND
Bioresponsive nanogels with a crosslinked three-dimensional structure and an aqueous environment that undergo physical or chemical changes including swelling and dissociation in response to biological signals such as mild acidity, hyperthermia, enzymes, reducing agents, reactive oxygen
