Anaplastology ISSN: 2161-1173 Anaplastology, an open access journal Volume 3 • Issue 1 • 1000125 methacrylates are durable they are relatively hard whereas silicones are flexible and soft. Pigmentation to replicate hair and skin features can be easily incorporated. It has an ability of stretching to an extent that it can become transparent at the corners and therefore blends smoothly with the s...
Polymerization of ethylene by complexes [{(P^O)PdMe(L)}] (P^O = κ(2)-(P,O)-2-(2-MeOC(6)H(4))(2)PC(6)H(4)SO(3))) affords homopolyethylene free of any methyl methacrylate (MMA)-derived units, even in the presence of substantial concentrations of MMA. In stoichiometric studies, reactive {(P^O)Pd(Me)L} fragments generated by halide abstraction from [({(P^O)Pd(Me)Cl}μ-Na)(2)] insert MMA in a 1,2- as...
Thiol-ene systems demonstrate numerous advantageous polymerization properties in regards to rapid curing, high conversion, minimal oxygen inhibition, and reduced shrinkage stress. However, one of the drawbacks of thiol-ene systems is that commercially available monomers are not able to achieve the mechanical properties required for use as dental restorative materials. Methacrylate systems on th...
Does the conformation of adsorbed fibrinogen dictate platelet interactions with artificial surfaces?
Platelet activation by polymer surfaces is thought to require preliminary adsorption of fibrinogen and perhaps changes in fibrinogen conformation. We measured fibrinogen adsorption by a series of polymers by two methods, using either 125I-labeled fibrinogen or 125I-labeled antifibrinogen antibodies, and correlated the results with platelet reactivity (retention and secretion) in columns of bead...
