Tobramycin-Impregnated Methylmethacrylate for Mandible Reconstruction

Archives of Otolaryngology - Head and Neck Surgery, 1992
Reconstruction of the mandible to restore continuity following resection is described in four cases using a tobramycin-impregnated methylmethacrylate implant fabricated at the time of surgery. Methylmethacrylate has excellent biocompatibility and strength and has been used in surgery for over 20 years. The technique uses readily available materials and

Preparation and Characterization of Insulin Nanoparticles Employing Chitosan and Poly(methylmethacrylate/methylmethacrylic acid) Copolymer

Journal of Nanoscience and Nanotechnology, 2006
As most of polypeptides are marginally stable, a mild formulation procedure would be beneficial for the activities of these drugs. The objective of the present study was to develop a novel pH-sensitive nanoparticle system that was suitable for entrapment of hydrophilic insulin but without affecting its conformation.

Arterial Occlusion Secondary to Methylmethacrylate Use

Archives of Surgery, 1976
We are reporting a new complication of the use of methylmethacrylate, namely occlusion of the iliac artery with embolization. We believe that the occlusion is related to trauma to the intima by the heat of polymerization created by methylmethacrylate, with resultant thrombosis.

Posterior Spine Stabilization with Methylmethacrylate

Spine, 1977
This paper reports a biomechanical study of a surgical specimen consisting of a spine segment from C2 to T4 with fracture at C6–7, stabilized by wires and methylmethacrylate. Biomechanical testing involved rigidly fixing the specimen atT3–4 and applying increasing flexion load at C2.

Negative Charge Carrier Transport in Poly(methylmethacrylate-co-9-anthracenyl-methylmethacrylate) Thin Films

physica status solidi (b), 2000
We have investigated the current-voltage characteristics of devices made of poly(methylmethacrylate-co-9-anthracenyl-methylmethacrylate) (10:1) sandwiched between aluminium electrodes. We found that the negative charge carrier mobility in this copolymer is equal to 3 x 10 -11 cm 2 /Vs and that the negative charge carrier traps are distributed ...

Efficient removers for poly(methylmethacrylate)

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2002
As nanotechnology approaches molecular scales, issues of surface contamination by unremoved resists will play an important role in device fabrication. Electron beam lithography of polymethylmethacrylate (PMMA) resist is still among the most widely used nanofabrication techniques, so it is relevant to study its residual contamination on both exposed and

Physical adsorption on poly(methylmethacrylate)

Journal of Colloid Science, 1965
Abstract Isotherms for the adsorption of nitrogen and argon on poly(methylmethacrylate) were obtained at three temperatures over a pressure range from a few microns to the saturated vapor pressure of the adsorbing gas. Differential and integral enthalpies and entropies were calculated and indicate a heterogeneous surface with adsorption energies ...
